PART I ITEM 1. BUSINESS. OVERVIEW We are a leading energy services company involved in projects from the shallowest to the deepest waters of the Gulf of Mexico. We have a reputation for innovation in our subsea construction techniques, equipment design and methods of partnering with customers. Our diversified fleet of 23 vessels and 19 remotely operated vehicles (ROVs) performs services that support drilling, well completion, construction and decommissioning projects involving pipelines, production platforms, risers and subsea production systems. We also acquire interests in natural gas and oil properties and related production facilities as part of our Production Partnering business. Our customers include major and independent natural gas and oil producers, pipeline transmission companies and offshore engineering and construction firms. We have positioned for work in water depths greater than 1,000 feet (the "Deepwater") by assembling a technically advanced fleet of dynamically positioned (DP) vessels and ROVs and a highly experienced group of support professionals. Our DP vessels serve as work platforms for subsea solutions provided by us working with our alliance partners, a team of internationally recognized contractors and manufacturers. Our new ROV subsidiary, Canyon Offshore, Inc., offers survey, engineering, repair, maintenance and international cable burial services. We are also a leader in solving the challenges encountered in Deepwater construction, with many of our projects using methods we have developed. Most notably, our newest and most advanced Deepwater semi-submersible multi-service vessel ("MSV"), the Q4000, incorporates our latest patented technologies. We anticipate that the Q4000 will improve Deepwater completion and construction economics for our customers. Availability of our Q4000, Eclipse and Mystic Viking, together with the soon to be completed Intrepid (formerly Sea Sorceress), will result in CDI offering the largest permanently deployed fleet of DP vessels in the Gulf of Mexico (GOM). On the Outer Continental Shelf (OCS) in water depths up to 1,000 feet, we perform traditional subsea services, including air and saturation diving and salvage work. Our subsidiary, Aquatica, Inc., provides full compliment services in the shallow water market from the shore to 300 fsw. The acquisition of the assets of Professional Divers of New Orleans, Inc. early in 2001 added important vessel and offshore personnel capacity. In the OCS "spot market", projects are generally turnkey in nature, short in duration (two to thirty days) and require constant rescheduling and availability of multiple vessels. Fifteen of our vessels perform traditional diving services and six of them support saturation diving. The technical and operational experience of our personnel and the scheduling flexibility offered by our large fleet enables us to manage turnkey projects to satisfy customers' requirements and achieve our targeted profitability. We have also established a leading position in the salvage market by offering customers a number of options to address decommissioning obligations in a cost-efficient manner, particularly in the removal of smaller structures. Our alliance with Horizon Offshore, Inc. provides derrick barge and heavy lift capacity for the removal of larger structures. In our Production Partnering business, our subsidiary Energy Resource Technology, Inc. ("ERT") is one of a few companies with the skills required to profitably acquire and operate mature natural gas and oil properties in the Gulf. The reservoir engineering and geophysical disciplines of ERT also enabled us to acquire a working interest in the Gunnison prospect, a Gulf Deepwater oil and natural gas exploration project in partnership with the operator Kerr-McGee Oil & Gas Corporation. We anticipate that this investment will both generate significant income in the future and will also help secure utilization for our subsea assets. As this project has now been sanctioned, we are already participating in field development planning and will collaborate with the other working interest owners in executing subsea construction work. We plan to again expand our Partnering strategy through our recent Letter of Intent to participate in the ownership of the Marco Polo production facility. Owning 50% of this proposed tension-leg platform in a joint venture with El Paso Energy Partners, when financed, would be designed to generate good returns and also have upside potential for both our construction work and ERT farm-in opportunities. Our overall corporate goal has been to increase shareholder value by focusing on strengthening our market position to provide a return which leads our peer group. Our return on capital employed (ROCE) in 2

2001 was 12% in contrast to the 4% average of our peer group; we have averaged an ROCE of 16% over the past five years versus the 6% average of our peers. We have been able to achieve our ROCE objective by focusing on the following business strengths and strategies: OUR STRENGTHS Diversified Fleet of Vessels and ROVs: Our fleet is the largest permanently deployed in the GOM and has one of the most diverse and technically advanced collections of subsea construction, maintenance and decommissioning project capabilities. These comprehensive services provided by our vessels are both complementary and overlapping, enabling us to assure customers the redundancy essential for most projects but especially in the Deepwater. Our new ROV based remote systems capabilities are critical to Deepwater construction and well intervention operations and Canyon's submarine cable burial business provides a platform for international operations and revenue diversification. Experienced Personnel and Turnkey Contracting: A key element of our growth strategy has been our ability to hire, attract and retain experienced personnel who we believe are the best in the industry at providing turnkey contracting. We believe the recognized skill of our personnel and our successful operating history uniquely position us to capitalize on the trend in the oil and gas industry of increased outsourcing to contractors and suppliers. Major Provider of Marine Construction Services on the OCS: We believe that our expansion of Aquatica, our alliance with Horizon and our dominant position in the GOM for saturation diving services makes us the largest supplier of such services on the OCS. Depletion of existing reserves, coupled with increased demand for natural gas, should require exploitation and development of OCS reservoirs. Production Partnering: The strategy of ERT's gas production business differentiates us from our competitors and helps to offset the cyclical nature of our marine construction operations. ERT's acquisition, sale and exploitation programs for mature properties on the OCS will be greatly expanded by the ownership of Deepwater assets such as the Gunnison project and the Marco Polo facility prospect. Leader in Decommissioning Operations: Over the last decade, we have established a leading position in decommissioning offshore facilities, particularly in the removal of the smaller structures and caissons which make up 52% of the market. We expect demand for decommissioning services to increase due to the significant backlog of platforms and caissons that must be removed in accordance with government regulations. OUR STRATEGIES Focusing on the Gulf: We will continue to focus on the GOM basin, where we have provided marine construction services since 1975. We expect natural gas and oil exploration and development activity in the Gulf, particularly in the Deepwater regions, to increase significantly in the next several years. Capturing a Significant Share of the Deepwater Market: We expect to benefit from the anticipated increase in Deepwater Gulf activity through our expanded fleet of seven DP vessels, the most any company has permanently deployed in the Gulf. Together with our alliance partners, we provide customers integrated solutions which minimize project duration and cost. Develop Well Operations Niche: We are employing more Deepwater assets, construction techniques and technologies focused upon servicing upstream market niches, such as pre-drilling services, well operations and vessels that offer cost-effective alternatives to services generally provided by drilling rigs. Examples include: the enhanced well intervention and completion design of the Q4000 and Uncle John and; the pipelay and platform support capability of the Eclipse and Intrepid. GOM well operations is a new niche for us. We believe the modification of the Q4000 will prove economically advantageous to our customers needing this service. Building Alliances to Expand the Scope of Our Services and Technology: We have alliance agreements with a team of domestic and internationally recognized contractors and manufacturers. These alliances enable us to offer state-of-the-art products and services while maintaining our low overhead base. 3

Maximizing the Value of Mature Natural Gas and Oil Properties: Through ERT, we acquire and produce mature, non-core offshore property interests, offering customers a cost-effective alternative for customers to the decommissioning process. Since its inception in 1992, ERT has delivered a 30% average annual return on its invested capital. Partnering with Customers: In 2000, we expanded the ERT business strategy to Deepwater prospects through a 15% equity participation in the Gunnison prospect. Total Proven reserves at 2001 year-end grew to 100 BCFe with initial reserves of 76.5 BCFe assigned to our ownership position in Gunnison. Our recently announced Letter of Intent to own 50% of the tension-leg platform at Anadarko's Marco Polo field, when financed, could extend the concept of acquiring oil and gas assets to earn a return while also securing the associated marine construction work. SUMMARY OF 2001 DEVELOPMENTS THIS "SUMMARY OF 2001 DEVELOPMENTS" IS INCOMPLETE BY IT NATURE, MAY OMIT MATERIAL INFORMATION, AND IS QUALIFIED IN ITS ENTIRETY BY MORE DETAILED INFORMATION CONTAINED ELSEWHERE IN THIS FORM 10-K, INCLUDING THE FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA. By most measures, 2001 was an outstanding year for us even though commodity prices plummeted and a significant increase in offshore construction activity failed to materialize. As a result, we were able to achieve most of our stated 2001 goals, including: i. Financial: Delivered ROCE of 12%. ii. Deepwater Contracting: Purchased additional Deepwater assets. iii. Well Operations: Undertook Q4000 enhancements. iv. Production Contracting: Gunnison sanctioned and identified our Marco Polo prospect. v. OCS: Acquired additional assets and extended the Horizon Alliance. vi. Safety: Implemented an enhanced EHS management system. In 2001, for a second time, Forbes magazine named us one of America's 200 best small companies. Our ranking was 109th overall, and we were one of only two oilfield service companies to qualify for this year's list. Articles accompanying the October 29 issue note that the sliding economy reshaped what it meant to be among the best small companies. Rankings were based on six equally weighted metrics: return on equity, sales and earnings-per-share growth, each measured over the past five years and the most recent four quarters. As a result, fewer than 1% of eligible companies made this list. We believe our ability to grow sales and earnings through a decline in the market for offshore services, while delivering a five-year average return on capital of 16%, highlights the value of our counter-cyclical strategy. This counter-cyclical strategy, whereby we acquire interests in oil and gas properties to secure the related marine contracting work, provides a natural hedge in energy industry downturns. HIGHLIGHTS OF 2001 OPERATING DEVELOPMENTS: 2001 was a roller-coaster year in our market for many reasons, including commodity prices. We believe, however, that three basic factors work in favor of our long-term business model: (i) the Deepwater GOM is an oil play with many large projects "on-course" despite the prices; (ii) the decline in natural gas prices should provide ERT and our Production Partnering strategy with more opportunities; and (iii) Gunnison will provide subsea construction work and then production related cash to fund growth. DEEPWATER CONTRACTING In anticipation of developments relating to our long-term business plan in the Deepwater, we had success in four areas in 2001: expansion of non-U.S. markets; acquiring more Deepwater vessels; acquiring our ROV 4

subsidiary, Canyon, and; implementing our Well Operations Group. Overall revenues in this segment were just under $80 million or 35% of our consolidated total revenue (up from 28% in 2000). Our decision to accelerate regulatory inspections in 2000 proved useful in achieving 87% utilization (vs 56% in 2000) for our deepwater vessels, particularly the Witch Queen and the Uncle John. The Witch Queen worked in Mexican waters for Horizon/Pemex for 14 consecutive months through the third quarter, then mobilized to Trinidad for BP and other customers. The Merlin provided ROV support to the Allseas Lorelay pipelay vessel for its summer campaign and then was involved in the large Nansen/Boomvang project. After her May acquisition, the Mystic Viking was deployed in Mexican waters for the second half of the year. All work was performed well and represents the potential of future growth in these non-U.S. markets. With GOM work for our vessels available but world construction activity low, we took the opportunity to grow our fleet to service Deepwater projects. The Mystic Viking purchase replaced the Balmoral Sea with more capacity. In October, we announced the purchase of the Eclipse, a large mono-hull with significant deck load capacity. These vessels together with our exiting fleet provide seven world class DP vessels to help assure scheduling flexibility for the technological challenges of Deepwater. As another part of our Deepwater puzzle, we purchased the ROV business of our new subsidiary, Canyon. Canyon represents an integration which is consistent with our policy of directly controlling all aspects on the critical path of significant projects. As marine construction support in the Gulf of Mexico moves to deeper waters, ROV systems will play an increasingly important role. Canyon currently owns 18 ROV systems and operates seven others in three regions: United States (13), Southeast Asia (8), and the North Sea (4). It also operates eight trenching systems internationally, including four customer-owned units. In the second and third quarters, our newly assembled team of well operation specialists, working in tandem with Alliance partner Schlumberger from the Uncle John work platform, tackled intervention projects at three subsea wells. Each job involved through-tubing, subsea well decommissioning operations employing slickline, E-line, cementing, coiled tubing and fluid handling services. The Uncle John worked every available day during the year (93% utility) because of her flexibility to perform both well intervention and marine construction operations. We believe this highlights potential market demand for well operations work by the Q4000. Other major well operations projects completed during 2001 include: Conoco -- world's first use of the Schlumberger Sen Tree 3 system as an open water riser system from a DP vessel in a shallow water live well intervention; and FMC -- jointly developed the world's first 15,000 psi intervention riser for operations to 10,000 fsw. In addition, the 2001 Deepwater geotechnical coring campaign with Alliance partner Fugro involved work at Gunnison, Thunderhorse (formerly Crazy Horse), Holstein and Devil's Tower among others. SHELF CONTRACTING In our OCS business, Aquatica delivers our services in the shallow water market (from the beach to 300 fsw). In March 2001, Aquatica acquired substantially all of the assets of Professional Divers which included three utility vessels and a four-point moored DSV. OCS revenues increased at a rapid pace during 2001 in response to both a spike in drilling activity and the doubling of our DSV fleet for a second year in a row -- this time from five vessels to ten. The call-out nature of this business allows us to adjust rates quickly as market conditions develop. These factors combined to generate $37 million of 2001 revenues, an 80% improvement over the prior year. In early 2001, our OCS Alliance with Horizon Offshore was extended for three years. Under the Alliance, we provide DSVs to support Horizon pipelay barges while Horizon supplies, derrick barge and heavy lift capacity to us. In addition, we took over all Horizon barge diving effective May 1, a low-margin activity we view as a contribution to the success of the alliance. Three of our DSVs work the Outer Continental Shelf virtually all in support of Horizon pipelay activity. This alliance and our work together in Mexico resulted in Horizon becoming our largest customer, accounting for 18% of revenues in 2001. For the second consecutive year OCS salvage revenues and margins were disappointing. In part, this is a result of high commodity prices in 2000 that led producers to push the last possible production out of their older properties. Because of the decline in commodity prices during 2001, these properties are now appearing 5

on the market with negative asset values. As a result, we expect that many will go directly to decommissioning, a development that suggests increased salvage demand in 2002 and 2003. Finally, we introduced a company-wide effort to enhance our behavioral safety process (BSP) and training that makes safety a constant focus of awareness through open communication with all offshore and yard employees. First year results from this program were impressive as our safety rating improved dramatically in 2001. PRODUCTION PARTNERING This segment which differentiates us from our Peer Group, was part of the 2001 commodity based roller-coaster. In the first part of the year, ERT contributed significantly to our earnings due to high production and realized gas prices before prices collapsed in the second half. Gas and oil revenues of $63.4 million declined by 10% with virtually all of that attributable to production of 13.9 BCFe versus 15.5 BCFe the prior year. Fortunately, production was at the high end of our expectation (14BCFe) without the benefit of significant acquisitions. ERT's management team did an outstanding job conducting an aggressive and successful exploitation program resulting in near replacement of reserves. 2001 closed with 24.5 BCFe of proven reserves in contrast to 28.2 BCFe a year earlier. Also in 2001, our Deepwater ERT plan succeeded as initial reserves of 76.5 BCFe were assigned to our ownership position in Gunnison. This figure represents 15% of the reserves reported by the operator, Kerr-McGee Oil & Gas Corporation, at December 31, 2001. The affiliated limited partnership that assumed the exploratory risk funded $21.5 million of drilling costs, considerably above the initial $15 million estimate. Our share of the ensuing project development costs is estimated in a range of $100 million to $110 million with over half of that for construction of the spar. The full potential of the three Gunnison blocks will be better defined a year from now as the operator plans an extensive development program in 2002. The development timetable schedules our marine construction activities for 2003 with first production anticipated early in 2004. The field is now expected to begin production in 2004. During 2001 we took another step to expanding our Production Partnering concept by signing a Letter of Intent to own 50% of the Marco Polo production facility at 4300 fsw. When financed, we would assist with the installation of the tension-leg platform which would be operated with El Paso Energy Partners on a fixed-fee-plus-tariff basis. INTRODUCTION TO SUBSEA CONSTRUCTION The offshore oilfield services industry in the Gulf originated in the early 1950s to assist companies as they began to explore and develop offshore fields. The industry has grown significantly since the early 1970s as the domestic natural gas and oil industry has increasingly relied upon these fields for new production. The oilfield services industry benefits from a number of trends including the following: - Lack of growth in natural gas production and failure to construct new assets in the face of foreign dependency and increasing demand. - Advances in exploration, extraction and production technology that have enabled industry participants to more cost-effectively enter the Gulf Deepwater. - Increased demand for decommissioning services as the offshore natural gas and oil continues to mature. In response to the natural gas and oil industry's migration to the Deepwater, equipment and vessel requirements have changed. Most vessels currently operating in the Deepwater Gulf were designed in the 1970s and 1980s for work in a maximum depth of approximately 1,000 feet. These vessels have been modified to take advantage of new technologies and now operate in depths up to 4,000 feet. We believe there is unmet demand in the Gulf for new generation vessels, such as the Q4000 and Intrepid, that are specifically designed to work in water depths up to 10,000 feet. 6

Defined below are certain terms and ideas helpful to understanding the services we perform in support of offshore development: BCFe: When describing oil and natural gas, the term converts oil volumes to their energy equivalent in natural gas and combines them in billions of cubic feet equivalent (BCFe). Deepwater: Water depths beyond 1,000 feet fsw. Dive Support Vessel (DSV): Specially equipped vessel which performs services and acts as an operational base for divers, ROVs and specialized equipment. Dynamic Positioning (DP): Computer-directed thruster systems that use satellite-based positioning and other positioning technologies to ensure the proper counteraction to wind, current and wave forces enable the vessel to maintain its position without the use of anchors. Two DP systems (DP-2) are necessary to provide the redundancy required to support safe deployment of divers, while only a single DP system is necessary to support ROV operations. DP-2: Redundancy allows the vessel to maintain position even with failure of one DP system. Required for vessels which support both manned diving and robotics, and for those working in close proximity to platforms. EBITDA: Earnings before interest, taxes, depreciation and amortization is a supplemental financial measure of cash flow used in the evaluation of the marine construction industry. EHS: Environment, Health and Safety programs that protect the environment, safeguard employee health and eliminate injuries. E&P: Companies involved in oil and gas exploration and production activities. Full Field Development: The ability to offer to oil and gas companies a range of services from subcontracting to complete field development solutions. These include procurement and installation of flowlines, wellheads, control systems, umbilicals and manifolds, as well as installation and commissioning of the complete production system. Many oil and gas companies prefer to contract with a company capable of undertaking the entire field development project or major portions of it. Full field development services can relieve a customer of substantial management burdens. Life of Field Services: Includes services performed on facilities, trees and pipelines from the beginning to the economic end of the life of an oil field, including installation, inspection, maintenance, repair, contract operations, well intervention, recompletion and abandonment. MBbl: When describing oil, refers to 1,000 barrels containing 42 gallons each. Minerals Management Service (MMS): The government regulatory body having responsibility for United States waters in the Gulf. MMcf: When describing natural gas, refers to 1 million cubic feet. Moonpool: An opening in the center of a vessel through which a saturation diving system or ROV may be deployed, allowing safe deployment in adverse weather conditions. Outer Continental Shelf (OCS): For purposes of our industry, areas in the Gulf from the shore to 1,000 feet of water. Peer Group: Defined in this report as comprising Global Industries, Ltd. (Nasdaq: GLBL), Horizon Offshore, Inc. (Nasdaq: HOFF), McDermott International, Inc. (NYSE: MDR), Oceaneering International, Inc. (NYSE: OII), Stolt Offshore SA (Nasdaq: SOSA), Technip-Coflexip (NYSE: TKP), and Torch Offshore, Inc. (Nasdaq: TORC). Remotely Operated Vehicle (ROV): Robotic vehicles used to complement, support and increase the efficiency of diving and subsea operations and for tasks beyond the capability of manned diving operations. 7

ROCE: Return on Capital Employed is the amount, expressed as a percentage, earned on a company's total capital (shareholders' equity plus long-term debt). It is calculated by dividing earnings before interest and dividends by total capital. Saturation Diving: Saturation diving, required for work in water depths between 300 and 1,000 feet, involves divers working from special chambers for extended periods at a pressure equivalent to the pressure at the work site. Spar: Floating production facility anchored to the seabed with catenary mooring lines. Spot Market: Prevalent market for subsea contracting in the Gulf, characterized by projects generally short in duration and often of a turnkey nature. These projects often require constant rescheduling and the availability or interchangeability of multiple vessels. Subsea Construction Vessels: Subsea services are typically performed with the use of specialized construction vessels which provide an above-water platform that functions as an operational base for divers and ROVs. Distinguishing characteristics of subsea construction vessels include DP systems, saturation diving capabilities, deck space, deck load, craneage and moonpool launching. Deck space, deck load and craneage are important features of the vessel's ability to transport and fabricate hardware, supplies and equipment necessary to complete subsea projects. Ultra-Deepwater: Water depths beyond 4,000 fsw. SUBSEA CONTRACTING We and our alliance partners provide a full range of subsea construction services, including the following, in both the OCS and Deepwater Gulf: - Exploration. Pre-installation surveys; rig positioning and installation assistance; drilling inspection; subsea equipment maintenance; well completion; search and recovery operations. - Development. Installation of production platforms; installation of subsea production systems; pipelay support including connecting pipelines to risers and subsea assemblies; pipeline stabilization, testing and inspection; cable and umbilical lay and connection. - Production. Inspection, maintenance and repair of production structures, risers and pipelines and subsea equipment; well intervention; life of field support. - Decommissioning. Decommissioning and remediation services; plugging and abandonment services; platform salvage and removal; pipeline abandonment; site inspections. Deepwater Contracting and Well Operations In 1994, we began to assemble a fleet of DP vessels in order to deliver subsea services in the Deepwater and Ultra-Deepwater. Our fleet consists of: two (2) semi-submersible DP MSVs (the Q4000 and Uncle John); two (2) construction DP DSVs (the Witch Queen and Mystic Viking); two (2) larger mono-hull pipelay and constructions vessels (the Intrepid and the Eclipse) and two (2) ROV support vessels (the Merlin and the Northern Canyon). In 2001, vessel enhancements included the Q4000 (well completions) and the Intrepid (DP-2 capability and a 400-ton crane). The Q4000 has recently been completed, and both vessels are expected to be working in the second quarter of 2002. When all of our DP vessels begin work, we will have seven world class vessels permanently deployed in the Gulf of Mexico. With the acquisition of our new subsidiary, Canyon, we have increased our operated ROV and trenching fleet to 26. Our new subsidiary's 18 ROVs are designed for offshore construction (rather than drilling rig support) and its management team adds industry experience in a setting where our vessels can add value in support of its ROVs. As marine construction support in the Gulf of Mexico moves to deeper waters, ROV systems will play an increasingly important role. Canyon currently owns 18 ROV systems and operates seven others in three regions: United States (13), Southeast Asia (8), and the North Sea (4). Canyon's assets will 8

help to assure our customers of vessel availability and schedule flexibility to meet the technological challenges of Deepwater construction developments in the Gulf and internationally. With its experienced personnel, our Well Operations Group is intended to support downhole operations of the Uncle John and Q4000. Both vessels provide cost-effective alternatives for Deepwater operations. This business line involves drilling support (which includes pre-setting casings, setting trees and commissioning wells), life-of-field services (which include well intervention), decommissioning and abandonment. Previously there were few cost-effective solutions for subsea well operations to troubleshoot or enhance production, shift zones or perform recompletions, as most all of such work has been done from drill rigs. We are a leader in solving the operational challenges encountered in the Deepwater projects using methods or technologies we have developed. To enhance our ability to provide both full field development and life of field services, we have alliances with other offshore service and equipment providers. These alliances enable us to offer state-of-the-art products and services while maintaining our low overhead base. These alliances include: - FMC Corp. -- Well intervention hardware and risers - Fugro-McClelland Marine Geoscience, Inc. -- Geotechnical coring and survey - Horizon Offshore, Inc. -- Small diameter reeled pipelay equipment - Schlumberger Limited -- Deepwater downhole services - Shell Offshore, Inc. -- Vessels for well intervention While the DP market remained soft, the significant increase in utilization (87% versus 56% a year ago) reflects improved market share and an expansion in the scope of GOM deepwater installations. Major projects in 2001 were:

Shelf Contracting In water depths up to 1,000 feet (the OCS), we perform traditional subsea services including air and saturation diving in support of marine construction activities. Fifteen of our vessels perform traditional subsea services, and six support saturation diving. In addition, our highly qualified personnel have the technical and operational experience to manage turnkey projects to satisfy customers' requirements and achieve our targeted profitability. Aquatica delivers our services in the shallow water market (from the beach to 300 fsw). In March 2001, Aquatica acquired substantially all of the four vessels and business of Professional Divers and doubled the size of our DSV fleet. We also perform numerous projects on the OCS in an alliance with Horizon Offshore, Inc. In the late 1980's we demonstrated that pipelay operations would be much more effective if the expensive barge spreads simply laid the pipe, allowing our DSVs to follow along and perform the more time-consuming task of commissioning the line. Principal features of the Alliance are that we have the exclusive right to provide DSV services behind Horizon pipelay barges while Horizon supplies pipelay, derrick barge and heavy lift capacity to Cal Dive. The recent expansion of the Alliance also resulted in our providing the diving personnel working from Horizon barges, a service Horizon handled internally last year. Our interaction with Horizon is multi-faceted, including operations in addition to those that flow from the formal alliance to provide services on the OCS. For example, much of our work in Mexican waters has been subcontracted from Horizon. 9

Since 1989, we have undertaken a wide variety of decommissioning assignments, mostly on a turnkey basis. A recently revised study by the MMS estimates that the total cost of the GOM abandonment market is $8.0 billion. Cal Dive has established a leading position in the removal of smaller structures, such as caissons and well protectors, which represent 52% of the structures in the Gulf. PRODUCTION PARTNERING We formed ERT in 1992 to exploit a market opportunity to provide a more efficient solution to offshore abandonment. Its business plan has evolved into the concept of Production Partnering, the business segment that differentiates us from our competitors. Production Partnering offers customers the option of selling mature offshore fields and also expands our off-season salvage and decommissioning activity to enable us to support full field production development projects. The business advantages of our production business are fourfold. First, the financial smoothing of oil and gas revenues counteracts the lumpiness and the extreme volatility in the revenues and income which most offshore construction companies have reported in the past three years. In periods of excess capacity such as 2001, we have the flexibility to stay out of the competitive bid market, focusing instead upon negotiated contracts. Third, our oil and gas operations generate significant cash flow that has funded construction of assets such as the Q4000, Intrepid and Eclipse while enabling us to add technical talent to support our expansion into the new Deepwater frontier. Finally, the primary objective of each CDI investment in oil and gas properties is to secure the associated marine construction work. Within ERT, we have assembled a team of personnel with experience in geology, geophysics, reservoir engineering, drilling, production engineering, facilities management and lease operations. ERT makes its money in three ways: lowering salvage costs by using our assets, operating the field more cost effectively and extending reservoir life through well exploitation operations. The periodic collapses of commodity prices in the last few years removed some of the small companies which buy mature properties. In the past two years, however, two competitors have captured significant market share. In the face of this competition, our disciplined strategy resulted in completing only three small mature property acquisitions in 2001, as high commodity prices made such purchases difficult. Rather than chase the upcycle and pay too much for properties, our emphasis turned internally to extracting more value from the existing property base. ERT designed and executed a significant well enhancement program that resulted in adding 8.2 BCFe to proved reserves at a cost of $1.06 per Mcf. There are 142 announced commercial discoveries in the deepwater GOM that have yet to be brought into production. Many of these are smaller reservoirs that standing alone cannot justify the economics of a host production facility. As a result we expect that the Deepwater GOM will be developed in a hub and satellite field concept that resembles the approach the airline industry has used with regional hub locations. We see significant opportunities as this occurs. For example, Gunnison, our first Deepwater field development project, is a hub location where we will provide infrastructure and tie-back marine construction services. At the Marco Polo field, although final agreements and financing have not been agreed, our 50% ownership in the production facility would allow Cal Dive to realize a transmission return. In addition we seek to assist with the installation of the TLP and then work to develop the surrounding acreage which can be tied back to the platform by CDI construction vessels. CUSTOMERS Our customers include major and independent natural gas and oil producers, pipeline transmission companies and offshore engineering and construction firms. The level of construction services required by any particular customer depends on the size of that customer's capital expenditure budget devoted to construction plans in a particular year. Consequently, customers that account for a significant portion of contract revenues in one fiscal year may represent an immaterial portion of contract revenues in subsequent fiscal years. The percent of consolidated revenue of major customers was as follows: 2001-Horizon Offshore, Inc. (18%), Enron Corporation (10%); 2000-Enron Corporation (13%); and 1999-EEX Corporation (13%). We estimate that in 2001 we provided subsea services to over 211 customers. Our projects are typically of short duration and are 10

generally awarded shortly before mobilization. Accordingly, we believe backlog is not a meaningful indicator of future business results. COMPETITION The subsea services industry is highly competitive. While price is a factor, the ability to utilize specialized vessels, to attract and retain skilled personnel and to demonstrate a good safety record are also important. Our competitors on the OCS include Global Industries Ltd., Oceaneering International, Inc., Stolt Offshore S.A., Torch Offshore, Inc., and a number of smaller companies, some of which only operate a single vessel and often compete solely on price. For Deepwater projects, our principal competitors include Global Industries Ltd., Oceaneering International, Inc., Stolt Offshore S.A., and Technip-Coflexip. Other foreign-based subsea contractors, including DSND Ltd., Rockwater, Ltd. and Saipem S.p.A., may periodically perform services in the Gulf. ERT encounters significant competition for the acquisition of mature natural gas and oil properties. Two such competitors are Tetra Technologies, Inc. and Offshore Specialty Fabricators. Our ability to acquire additional properties depends upon our ability to evaluate and select suitable properties and to consummate transactions in a highly competitive environment. Many of our competitors are well-established companies with substantially larger operating staffs and greater capital resources. TRAINING, SAFETY AND QUALITY ASSURANCE As work levels increase on the OCS, safety, our single most important objective, will be even more important because the projects in these water depths are more personnel-intensive. Over 35 years Cal Dive has continuously upgraded and revitalized so that environment, health and safety (EHS) at work are embraced as core business values. Our Executive EHS Steering Committee, chaired by the President and Vice Presidents, meets monthly to decide on strategy and action plans for improvements. Our behavioral safety process (BSP) empowers employees to take control of their own safety at work using proven techniques of employees observing each other for correct and safe behavior. During 2001, we introduced a company-wide program to enhance the BSP and training that makes safety a constant focus of awareness through open communication with all offshore and yard employees. Management believes that our safety programs are among the best in the industry. GOVERNMENT REGULATION Many aspects of the offshore marine construction industry are subject to extensive governmental regulation. We are subject to the jurisdiction of the Coast Guard, the Environmental Protection Agency, MMS and the U.S. Customs Service, as well as private industry organizations such as the American Bureau of Shipping. We support and voluntarily comply with standards of the Association of Diving Contractors International. The Coast Guard sets safety standards and is authorized to investigate vessel and diving accidents, and to recommend improved safety standards. The Coast Guard also is authorized to inspect vessels at will. We are required by various governmental and quasi-governmental agencies to obtain various permits, licenses and certificates with respect to our operations. We believe that we have obtained or can obtain all permits, licenses and certificates necessary for the conduct of our business. In addition, we depend on the demand for our services from the oil and gas industry and, therefore, our business is affected by laws and regulations, as well as changing taxes and policies relating to the oil and gas industry generally. In particular, the development and operation of natural gas and oil properties located on the OCS of the United States is regulated primarily by the MMS. The MMS requires lessees of OCS properties to post bonds in connection with the plugging and abandonment of wells located offshore and the removal of all production facilities. Operators on the OCS are currently required to post an area-wide bond of $3.0 million, or $500,000 per producing lease. We currently 11

have bonded our offshore leases as required by the MMS. Under certain circumstances, the MMS has the authority to suspend or terminate operations on federal leases. Any such suspensions or terminations of our operations could have a material adverse effect on our financial condition and results of operations. We acquire production rights to offshore mature natural gas and oil properties under federal natural gas and oil leases, which the MMS administers. These leases contain relatively standardized terms and require compliance with detailed MMS regulations and orders pursuant to the Outer Continental Shelf Lands Act (OCSLA). These MMS directives are subject to change. The MMS has promulgated regulations requiring offshore production facilities located on the OCS to meet stringent engineering and construction specifications. The MMS also has issued regulations restricting the flaring or venting of natural gas and prohibiting the burning of liquid hydrocarbons without prior authorization. Similarly, the MMS has promulgated other regulations governing the plugging and abandonment of wells located offshore and the removal of all production facilities. Finally, under certain circumstances, the MMS may require any operations on federal leases to be suspended or terminated. In December 1999, the MMS issued regulations that would allow it to expel unsafe operators from existing OCS platforms and bar them from obtaining future leases. Under the OCSLA, MMS also administers oil and gas leases and establishes regulations that set the basis for royalties on oil and gas produced from the leases. The MMS amends these regulations from time to time. For example, on March 15, 2000, the MMS issued a final rule governing the calculation of royalties and the valuation of crude oil produced from federal leases. The rule modifies the valuation procedures for both arm's length and non-arm's length crude oil transactions to decrease reliance on oil posted prices and assign a value to crude oil that better reflects market value. The rule has been challenged by two industry trade associations and is currently under judicial review in the United States District Court for the District of Columbia. In addition, the MMS recently issued a final rule amending its regulations regarding costs for natural gas transportation which are deductible for royalty valuation purposes when natural gas is sold off-lease. Among other matters, for purposes of computing royalty owed, the rule disallows as deductions certain costs, such as aggregator/marketer fees and transportation imbalance charges and associated penalties. A United States District Court, however, enjoined substantial portions of this rule on March 28, 2000. The United States appealed the district court decision and the case is pending before the Court of Appeals for the District of Columbia Circuit. Historically, the transportation and sale for resale of natural gas in interstate commerce has been regulated pursuant to the Natural Gas Act of 1938, the Natural Gas Policy Act of 1978 (NGPA) and the regulations promulgated thereunder by the Federal Energy Regulatory Commission (FERC). In the past, the federal government has regulated the prices at which natural gas and oil could be sold. While sales by producers of natural gas, and all sales of crude oil, condensate and natural gas liquids currently can be made at uncontrolled market prices, Congress could reenact price controls in the future. Deregulation of wellhead sales in the natural gas industry began with the enactment of the NGPA. In 1989, the Natural Gas Wellhead Decontrol Act was enacted. This act amended the NGPA to remove both price and non-price controls from natural gas sold in "first sales" no later than January 1, 1993. Sales of natural gas are affected by the availability, terms and cost of transportation. The price and terms for access to pipeline transportation remain subject to extensive federal and state regulation. Several major regulatory changes have been implemented by Congress and the FERC from 1985 to the present that affect the economics of natural gas production, transportation and sales. In addition, the FERC continues to promulgate revisions to various aspects of the rules and regulations affecting those segments of the natural gas industry, most notably interstate natural gas transmission companies that remain subject to FERC jurisdiction. These initiatives may also affect the intrastate transportation of natural gas under certain circumstances. The stated purpose of many of these regulatory changes is to promote competition among the various sectors of the natural gas industry. The ultimate impact of the complex rules and regulations issued by the FERC since 1985 cannot be predicted. In addition, many aspects of these regulatory developments have not become final but are still pending judicial and FERC final decisions. We cannot predict what further action the FERC will take on these matters but we do not believe any such action will materially affect CDI differently than other companies with which we compete. 12

Additional proposals and proceedings before various federal and state regulatory agencies and the courts could affect the natural gas and oil industry. We cannot predict when or whether any such proposals may become effective. In the past, the natural gas industry has been heavily regulated. There is no assurance that the regulatory approach currently pursued by the FERC will continue indefinitely. Notwithstanding the foregoing, we do not anticipate that compliance with existing federal, state and local laws, rules and regulations will have a material effect upon our capital expenditures, earnings or competitive position. ENVIRONMENTAL REGULATION Our operations are subject to a variety of federal, state and local laws and regulations governing the discharge of materials into the environment or otherwise relating to environmental protection. Numerous governmental departments issue rules and regulations to implement and enforce such laws that are often complex and costly to comply with and that carry substantial administrative, civil and possibly criminal penalties for failure to comply. Under these laws and regulations, we may be liable for remediation or removal costs, damages and other costs associated with releases of hazardous materials including oil into the environment, and such liability may be imposed on us even if the acts that resulted in the releases were in compliance with all applicable laws at the time such acts were performed. The Oil Pollution Act of 1990, as amended (OPA) imposes a variety of requirements on "responsible parties" related to the prevention of oil spills and liability for damages resulting from such spills in waters of the United States. A "responsible party" includes the owner or operator of an onshore facility, a vessel or a pipeline, and the lessee or permittee of the area in which an offshore facility is located. OPA imposes liability on each responsible party for oil spill removal costs and for other public and private damages from oil spills. Failure to comply with OPA may result in the assessment of civil and criminal penalties. OPA establishes liability limits of $350 million for onshore facilities, all removal costs plus $75 million for offshore facilities and the greater of $500,000 or $600 per gross ton for vessels other than tank vessels. The liability limits are not applicable, however, if the spill is caused by gross negligence or willful misconduct, if the spill results from violation of a federal safety, construction, or operating regulation, or if a party fails to report a spill or fails to cooperate fully in the cleanup. Few defenses exist to the liability imposed under OPA. Management is currently unaware of any oil spills for which we have been designated as a responsible party under OPA that will have a material adverse impact on us or our operations. OPA also imposes ongoing requirements on a responsible party, including preparation of an oil spill contingency plan and maintaining proof of financial responsibility to cover a majority of the costs in a potential spill. We believe we have appropriate spill contingency plans in place. With respect to financial responsibility, OPA requires the responsible party for certain offshore facilities to demonstrate financial responsibility of not less than $35 million, with the financial responsibility requirement potentially increasing up to $150 million if the risk posed by the quantity or quality of oil that is explored for or produced indicates that a greater amount is required. The MMS has promulgated regulations implementing these financial responsibility requirements for covered offshore facilities. Under the MMS regulations, the amount of financial responsibility required for an offshore facility is increased above the minimum amounts if the "worst case" oil spill volume calculated for the facility exceeds certain limits established in the regulations. We believe that we currently have established adequate proof of financial responsibility for our onshore and offshore facilities and that we satisfy the MMS requirements for financial responsibility under OPA and applicable regulations. OPA also requires owners and operators of vessels over 300 gross tons to provide the Coast Guard with evidence of financial responsibility to cover the cost of cleaning up oil spills from such vessels. We currently own and operate six vessels over 300 gross tons. Satisfactory evidence of financial responsibility has been provided to the Coast Guard for all of our vessels. The Clean Water Act imposes strict controls on the discharge of pollutants into the navigable waters of the U.S. and imposes potential liability for the costs of remediating releases of petroleum and other substances. The controls and restrictions imposed under the Clean Water Act have become more stringent over time, and it is possible that additional restrictions will be imposed in the future. Permits must be obtained to discharge pollutants into state and federal waters. Certain state regulations and the general permits issued 13

under the Federal National Pollutant Discharge Elimination System program prohibit the discharge of produced waters and sand, drilling fluids, drill cuttings and certain other substances related to the exploration for and production of oil and gas into certain coastal and offshore waters. The Clean Water Act provides for civil, criminal and administrative penalties for any unauthorized discharge of oil and other hazardous substances and imposes liability on responsible parties for the costs of cleaning up any environmental contamination caused by the release of a hazardous substance and for natural resource damages resulting from the release. Many states have laws which are analogous to the Clean Water Act and also require remediation of releases of petroleum and other hazardous substances in state waters. Our vessels routinely transport diesel fuel to offshore rigs and platforms and also carry diesel fuel for their own use. Our supply boats transport bulk chemical materials used in drilling activities and also transport liquid mud which contains oil and oil by- products. Offshore facilities and vessels operated by us have facility and vessel response plans to deal with potential spills of oil or its derivatives. We believe that our operations comply in all material respects with the requirements of the Clean Water Act and state statutes enacted to control water pollution. OCSLA provides the federal government with broad discretion in regulating the production of offshore resources of natural gas and oil, including authority to impose safety and environmental protection requirements applicable to lessees and permittees operating in the OCS. Specific design and operational standards may apply to OCS vessels, rigs, platforms, vehicles and structures. Violations of lease conditions or regulations issued pursuant to OCSLA can result in substantial civil and criminal penalties, as well as potential court injunctions curtailing operations and cancellation of leases. Because our operations rely on offshore oil and gas exploration and production, if the government were to exercise its authority under OCSLA to restrict the availability of offshore oil and gas leases, such action could have a material adverse effect on our financial condition and the results of operations. As of this date, we believe we are not the subject of any civil or criminal enforcement actions under OCSLA. The Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) contains provisions requiring the remediation of releases of hazardous substances into the environment and imposes liability, without regard to fault or the legality of the original conduct, on certain classes of persons including owners and operators of contaminated sites where the release occurred and those companies who transport, dispose of or who arrange for disposal of hazardous substances released at the sites. Under CERCLA, such persons may be subject to joint and several liability for the costs of cleaning up the hazardous substances that have been released into the environment, for damages to natural resources and for the costs of certain health studies. Third parties may also file claims for personal injury and property damage allegedly caused by the release of hazardous substances. Although we handle hazardous substances in the ordinary course of business, we are not aware of any hazardous substance contamination for which we may be liable. Management believes we are in compliance in all material respects with all applicable environmental laws and regulations to which we are subject. We do not anticipate that compliance with existing environmental laws and regulations will have a material effect upon our capital expenditures, earnings or competitive position. However, changes in the environmental laws and regulations, or claims for damages to persons, property, natural resources or the environment, could result in substantial costs and liabilities, and thus there can be no assurance that we will not incur significant environmental compliance costs in the future. EMPLOYEES We rely on the high quality of our workforce. As of March 26, 2002, we had 835 employees, 230 of which were salaried. As of that date we also utilized approximately 111 non-U.S. citizens to crew our foreign flag vessels under a crewing contract with C-MAR Services (UK), Ltd. of Aberdeen, Scotland. None of our employees belong to a union or are employed pursuant to any collective bargaining agreement or any similar arrangement. Management believes that our relationship with our employees and foreign crew members is good. 14

FACTORS INFLUENCING FUTURE RESULTS AND ACCURACY OF FORWARD-LOOKING STATEMENTS Shareholders should carefully consider the following risk factors in addition to the other information contained herein. This Annual Report on Form 10-K includes certain statements that may be deemed "forward-looking statements" within the meaning of Section 27A of the Securities Act and Section 21E of the Exchange Act. You can identify these statements by forward-looking words such as "anticipate," "believe," "budget," "could," "estimate," "expect," "forecast," "intend," "may," "plan," "potential," "should," "will" and "would" or similar words. You should read statements that contain these words carefully because they discuss our future expectations, contain projections of our future financial position or results of operations or state other forward-looking information. We believe that it is important to communicate our future expectations to our investors. However, there may be events in the future that we are not able to predict or control accurately. The factors listed below in this section, captioned "Factors Influencing Future Results And Accuracy of Forward-Looking Statements," as well as any cautionary language in this Annual Report, provide examples of risks, uncertainties and events that may cause our actual results to differ materially from the expectations we describe in our forward-looking statements. You should be aware that the occurrence of the events described in these risk factors and elsewhere in this Annual Report could have a material adverse effect on our business, results of operations and financial position. OUR BUSINESS IS ADVERSELY AFFECTED BY LOW OIL AND GAS PRICES AND BY THE CYCLICALITY OF THE OIL AND GAS INDUSTRY. Our business is substantially dependent upon the condition of the oil and gas industry and, in particular, the willingness of oil and gas companies to make capital expenditures on offshore exploration, drilling and production operations. The level of capital expenditures generally depends on the prevailing view of future oil and gas prices, which are influenced by numerous factors affecting the supply and demand for oil and gas, including: - Worldwide economic activity - Coordination by the Organization of Petroleum Exporting Countries (OPEC) - The cost of exploring for and producing oil and gas - The sale and expiration dates of offshore leases in the United States and overseas - The discovery rate of new oil and gas reserves in offshore areas - Technological advances - Interest rates and the cost of capital - Environmental regulation - Tax policies The level of offshore development and production activity did not increase materially in 2001 despite high commodity prices in the first half of the year. We cannot assure you that activity levels will increase anytime soon. A sustained period of low drilling and production activity or a return of low hydrocarbon prices would likely have a material adverse effect on our financial position and results of operations. THE OPERATION OF MARINE VESSELS IS RISKY, AND WE DO NOT HAVE INSURANCE COVERAGE FOR ALL RISKS. Marine construction involves a high degree of operational risk. Hazards, such as vessels sinking, grounding, colliding and sustaining damage from severe weather conditions, are inherent in marine operations. These hazards can cause personal injury or loss of life, severe damage to and destruction of property and equipment, pollution or environmental damage and suspension of operations. Damage arising from such occurrences may result in lawsuits asserting large claims. We maintain such insurance protection as we deem prudent, including Jones Act employee coverage (the maritime equivalent of workers' compensation) and hull 15

insurance on our vessels. We cannot assure you that any such insurance will be sufficient or effective under all circumstances or against all hazards to which we may be subject. A successful claim for which we are not fully insured could have a material adverse effect on us. Moreover, we cannot assure you that we will be able to maintain adequate insurance in the future at rates that we consider reasonable. As construction activity moves into deeper water in the Gulf, construction projects tend to be larger and more complex than shallow water projects. As a result, our revenues and profits are increasingly dependent on our larger vessels. While the loss of the Balmoral Sea was covered by insurance, the current insurance on our vessels (in some cases, in amounts approximating book value, which is less than replacement value) against property loss due to a catastrophic marine disaster, mechanical failure or collision may not cover a substantial loss of revenues, increased costs and other liabilities, and could have a material adverse effect on our operating performance if we lost any of our large vessels. OUR CONTRACTING BUSINESS DECLINES IN WINTER, AND BAD WEATHER IN THE GULF CAN ADVERSELY AFFECT OUR OPERATIONS. Marine operations conducted in the Gulf are seasonal and depend, in part, on weather conditions. Historically, we have enjoyed our highest vessel utilization rates during the summer and fall when weather conditions are favorable for offshore exploration, development and construction activities, and we have experienced our lowest utilization rates in the first quarter. As is common in the industry, we typically bear the risk of delays caused by some but not all adverse weather conditions. Accordingly, the results of any one quarter are not necessarily indicative of annual results or continuing trends. IF WE BID TOO LOW ON A TURNKEY CONTRACT WE SUFFER THE CONSEQUENCES. A majority of our projects are performed on a qualified turnkey basis where described work is delivered for a fixed price and extra work, which is subject to customer approval, is charged separately. The revenue, cost and gross profit realized on a turnkey contract can vary from the estimated amount because of changes in offshore job conditions, variations in labor and equipment productivity from the original estimates, and performance of others such as alliance partners. These variations and risks inherent in the marine construction industry may result in our experiencing reduced profitability or losses on projects. ESTIMATES OF OUR NATURAL GAS AND OIL RESERVES, FUTURE CASH FLOWS AND ABANDONMENT COSTS MAY BE SIGNIFICANTLY INCORRECT. This Annual Report contains estimates of our proved natural gas and oil reserves and the estimated future net cash flows therefrom based upon reports prepared for the years ended December 31, 2001, 2000 and 1999. Excluding the Gunnison reserves for the year ended December 31, 2001, these reports were reviewed by Miller and Lents, Ltd. This report relies upon various assumptions, including assumptions required by the Securities and Exchange Commission as to natural gas and oil prices, drilling and operating expenses, capital expenditures, abandonment costs, taxes and availability of funds. The process of estimating natural gas and oil reserves is complex, requiring significant decisions and assumptions in the evaluation of available geological, geophysical, engineering and economic data for each reservoir. As a result, these estimates are inherently imprecise. Actual future production, cash flows, development expenditures, operating and abandonment expenses and quantities of recoverable natural gas and oil reserves may vary substantially from those estimated in these reports. Any significant variance in these assumptions could materially affect the estimated quantity and value of our proved reserves. You should not assume that the present value of future net cash flows from our proved reserves referred to in this Form 10-K is the current market value of our estimated natural gas and oil reserves. In accordance with Securities and Exchange Commission requirements, we base the estimated discounted future net cash flows from our proved reserves on prices and costs on the date of the estimate. Actual future prices and costs may differ materially from those used in the net present value estimate. In addition, if costs of abandonment are materially greater than our estimates, they could have an adverse effect on earnings. Proved reserves at December 31, 2001 also included the initial reserves assigned to our ownership position in Gunnison. Since we do not own the seismic data for the three fields this figure represents 15% of the reserves reported by the operator, Kerr-McGee Oil & Gas Corporation. 16

THE GUNNISON PROSPECT MAY NOT RESULT IN THE EXPECTED CASH FLOWS OR SUBSEA ASSET UTILIZATION WE ANTICIPATE AND COULD INVOLVE SIGNIFICANT FUTURE CAPITAL OUTLAYS. The Gunnison prospect is subject to a number of assumptions and uncertainties, including estimates of the capital outlays necessary to develop the prospect and the cash flows that we may ultimately derive. We cannot assure you that we will be able to fund all required capital outlays or that these outlays will be profitable. Moreover, although our working interest entitles us to participate in field development and planning and to collaborate with the other working interest owners in executing subsea construction work, the extent of utilization of our subsea assets for such work has not been determined. EXPECTED CASH FLOWS FROM THE Q4000 AND INTREPID UPON COMPLETION MAY NOT BE IMMEDIATE OR AS HIGH AS EXPECTED. These vessels are scheduled to be placed into service in the second quarter of 2002. Additionally delays could also have a material adverse effect on expected utilization for these vessels and our future revenues and cash flows. We will not receive any material increase in revenue or cash flow from either vessel until placed in service. Furthermore, we cannot assure you of customer demand for the Q4000 as that vessel targets the well operations market and, as a result, our future cash flows may be adversely affected. While elements of this vessel design have been patented, new vessels from third parties may also enter the market in the coming years and compete with us for contracts. OUR NATURAL GAS AND OIL OPERATIONS INVOLVE SIGNIFICANT RISKS, AND WE DO NOT HAVE INSURANCE COVERAGE FOR ALL RISKS. Our natural gas and oil operations are subject to the usual risks incident to the operation of natural gas and oil wells, including, but not limited to, uncontrollable flows of oil, natural gas, brine or well fluids into the environment, blowouts, cratering, mechanical difficulties, fires, explosions, pollution and other risks, any of which could result in substantial losses to us. In accordance with industry practice, we maintain insurance against some, but not all, of the risks described above. WE MAY NOT BE ABLE TO COMPETE SUCCESSFULLY AGAINST CURRENT AND FUTURE COMPETITORS. The business in which we operate is highly competitive. Several of our competitors are substantially larger and have greater financial and other resources than we have. If other companies relocate or acquire vessels for operations in the Gulf, levels of competition may increase and our business could be adversely affected. THE LOSS OF THE SERVICES OF ONE OR MORE OF OUR KEY EMPLOYEES, OR OUR FAILURE TO ATTRACT, ASSIMILATE AND RETAIN OTHER HIGHLY QUALIFIED PERSONNEL IN THE FUTURE, COULD DISRUPT OUR OPERATIONS AND ADVERSELY AFFECT OUR FINANCIAL RESULTS. The industry has lost a significant number of experienced subsea people over the years due to, among other reasons, the decrease in commodity prices. Our continued success depends on the active participation of our key employees. The loss of our key people could adversely affect our operations. We believe that our success and continued growth are also dependent upon our ability to employ and retain skilled personnel. We believe that our wage rates are competitive; however, unionization or a significant increase in the wages paid by other employers could result in a reduction in our workforce, increases in the wage rates we pay, or both. If either of these events occurs for any significant period of time, our revenues and profitability could be diminished and our growth potential could be impaired. WE MAY NEED TO CHANGE THE MANNER IN WHICH WE CONDUCT OUR BUSINESS IN RESPONSE TO CHANGES IN GOVERNMENT REGULATIONS. Our subsea construction, inspection, maintenance and decommissioning operations and our natural gas and oil production from offshore properties (including decommissioning of such properties) are subject to and affected by various types of government regulation, including numerous federal, state and local environmental 17

protection laws and regulations. These laws and regulations are becoming increasingly complex, stringent and expensive. We cannot assure you that continued compliance with existing or future laws or regulations will not adversely affect our operations. Significant fines and penalties may be imposed for noncompliance. CERTAIN PROVISIONS OF OUR CORPORATE DOCUMENTS AND MINNESOTA LAW MAY DISCOURAGE A THIRD PARTY FROM MAKING A TAKEOVER PROPOSAL. Our Board of Directors has the authority, without any action by our shareholders, to fix the rights and preferences on up to 5,000,000 shares of undesignated preferred stock, including dividend, liquidation and voting rights. In addition, our Bylaws divide the Board of Directors into three classes. We are also subject to certain anti-takeover provisions of the Minnesota Business Corporation Act. We also have employment contracts with all of our senior officers which require cash payments in the event of a "change of control." Any or all of the provisions or factors described above may have the effect of discouraging a takeover proposal or tender offer not approved by management and the board of directors and could result in shareholders who may wish to participate in such a proposal or tender offer receiving less for their shares than otherwise might be available in the event of a takeover attempt. ITEM 2. PROPERTIES OUR VESSELS We own and operate a fleet of 23 vessels and 19 ROVs. Management believes that the GOM market requires specially designed and/or equipped vessels to competitively deliver subsea construction services. Seven of our vessels have DP capabilities specifically designed to respond to the Deepwater market requirements. Six of our vessels have the capability to provide saturation diving services. Recent developments in our fleet include: Q4000: In September 1999, we began construction of our newest Deepwater MSV, the Q4000. The vessel has been constructed at an estimated cost of $180 million and incorporates our latest semi-submersible technologies, including various patented elements such as the absence of lower hull cross bracing. Variable deck load of 3,400 metric tons upgraded well completions capability make the vessel particularly well suited for large offshore construction projects in the Ultra-Deepwater. Its Huisman-Itrec multi-purpose tower has an open face which allows free access from three sides, an advantage for a construction and intervention vessel. Another important feature of the Q4000 will be the new intervention riser system we are developing and jointly funding with FMC Corporation. This system will be the first in the industry rated for working pressures to 15,000 pounds per square inch in 10,000 fsw. The Q4000 will be in service in the second quarter of 2002. Intrepid: CDI is currently in the final stages of converting the former Sea Sorceress. While we refer to this as a conversion, the work constitutes the construction of new DP-2 pipelay vessel into the hull of our ice class vessel acquired three years ago. She will offer customers a construction vessel capable of carrying an 8,000 metric ton deckload. We expect her to be available for work the second quarter of 2002. Mystic Viking: The DPDSV is 240 feet long and 52 feet wide. Her class is similar to the Witch Queen with DP-2 redundancy, 500 ton load, 2 cranes and a 12 foot x 12 foot moonpool. This vessel was acquired in May of 2002. Eclipse: This large DPDSV is 370 feet long and 67 feet wide. She has recently been outfitted with her original marine construction features by installing a SAT diving system, restoring the ballast system and upgrading to DP-2. The Eclipse began work in March 2002. Northern Canyon: Canyon Offshore will take delivery of this purpose built, 270 foot state-of-the-art ROV support vessel which will be deployed initially in the North Sea. Robotics: To enable us to control critical path equipment involved in our deepwater projects, we acquired Canyon at the end of 2001. Canyon Offshore currently owns 18 ROVs and operates 7 trenching 18

systems. In 2001, Canyon introduced the next-generation work-class ROV, the Quest. Advantages of the Quest include: electric instead of hydraulic systems, 50% smaller footprint, fewer moving parts (i.e. lower operating costs), a dynamic positioning system and improved depth rating.

- --------------- (1) Under government regulations and our insurance policies, we are required to maintain our vessels in accordance with standards of seaworthiness and safety set by government regulations and classification organizations. We maintain our fleet to the standards for seaworthiness, safety and health set by the ABS, Det Norske Veritas ("DNV") and the Coast Guard. The ABS is one of several classification societies used by ship owners to certify that their vessels meet certain structural, mechanical and safety equipment standards, including Lloyd's Register, Bureau Veritas and DNV among others. 19

(2) In March 2001, CDI acquired substantially all of the assets of Professional Divers of New Orleans, Inc. including the Mr. Sonny (a 165-foot four-point moored DSV), three utility vessels and associated diving equipment including two saturation diving systems. (3) This leased vessel is under construction and should be available June 15, 2002. We incur routine drydock inspection, maintenance and repair costs pursuant to Coast Guard regulations and in order to maintain ABS or DNV classification for our vessels. In addition to complying with these requirements, we have our own vessel maintenance program which management believes permits us to continue to provide our customers with well maintained, reliable vessels. In the normal course of business, we charter other vessels on a short-term basis, such as tugboats, cargo barges, utility boats and dive support vessels. All of our vessels are subject to ship mortgages to secure our $60.0 million revolving credit facility with Fleet Credit Corporation, except the Northern Canyon (which will be leased) and the Q4000 (which is subject to liens to secure the MARAD financing). SUMMARY OF NATURAL GAS AND OIL RESERVE DATA The table below sets forth information, as of December 31, 2001, with respect to estimates of net proved reserves and the present value of estimated future net cash flows at such date for ERT (not including Gunnison), prepared by Company engineers in accordance with guidelines established by the Securities and Exchange Commission. Our estimates have been reviewed by Miller and Lents, Ltd., independent petroleum engineers.

TOTAL PROVED(2) --------------- (DOLLARS IN THOUSANDS) Estimated Proved Reserves: Natural Gas (MMcf)........................................ 18,410 Oil and Condensate (MBbls)................................ 1,029 Standardized measure of discounted future net cash flows (pre-tax)................................................. $16,439(1)
- --------------- (1) The standardized measure of discounted future net cash flows attributable to our reserves was prepared using constant prices as of the calculation date, discounted at 10% per annum. As of December 31, 2001, ERT owned (not including Gunnison) an interest in 122 gross (102 net) natural gas wells and 104 gross (79 net) oil wells located in federal offshore waters in the Gulf of Mexico. (2) Total proven reserves at year-end grew to 100 BCFe with initial reserves of 76.5 BCFe assigned to our ownership position in Gunnison. This figure represents 15% of the reserves reported by the operator, Kerr-McGee Oil & Gas Corporation, at December 31, 2001. FACILITIES Our headquarters is 400 N. Sam Houston Parkway E., Houston, Texas. Our primary subsea and marine services operations are based in Morgan City, Louisiana. All of our facilities are leased. 20

LEGAL PROCEEDINGS INSURANCE AND LITIGATION Our operations are subject to the inherent risks of offshore marine activity, including accidents resulting in personal injury and the loss of life or property, environmental mishaps, mechanical failures, fires and collisions. We insure against these risks at levels consistent with industry standards. We also carry workers' compensation, maritime employer's liability, general liability and other insurance customary in our business. All insurance is carried at levels of coverage and deductibles that we consider financially prudent. Our services are provided in hazardous environments where accidents involving catastrophic damage or loss of life could occur, and litigation arising from such an event may result in our being named a defendant in lawsuits asserting large claims. To date, we have been involved in only one such claim, where the cost of the Balmoral Sea was covered by insurance. Although there can be no assurance that the amount of insurance we carry is sufficient to protect us fully in all events (or that such insurance will continue to be available at current levels of cost or coverage), management believes that our insurance protection is adequate for our business operations. A successful liability claim for which we are underinsured or uninsured could have a material adverse effect on our business. We are involved in various legal proceedings, primarily involving claims for personal injury under the General Maritime Laws of the United States and the Jones Act as a result of alleged negligence. In addition, we from time to time incur other claims, such as contract disputes, in the normal course of business. In that regard, we entered into a subcontract with Seacore Marine Contractors Limited to provide the Sea Sorceress for subsea excavation in Canada. Seacore was in turn contracted by Coflexip Stena Offshore Newfoundland Limited, a subsidiary of Coflexip (CSO Nfl), as representative of the consortium of companies contracted to perform services on the project. Due to difficulties with respect to the sea states and soil conditions the contract was terminated. Cal Dive provided Seacore a performance bond of $5 million with respect to the subcontract. No call has been made on this bond. Although CSO Nfl has alleged that the Sea Sorceress was unable to adequately perform the excavation work required under the subcontract, Seacore and we believe the contract was wrongfully terminated and are vigorously defending this claim and seeking damages in arbitration. In another commercial dispute, EEX Corporation sued us and others alleging breach of fiduciary duty by a former EEX employee and damages resulting from certain construction and property acquisition agreements. We have responded alleging EEX Corporation breached various provisions of the same contracts and are seeking a declaratory judgment that the defendants are not liable. Although such litigation has the potential of significant liability, we believe that the outcomes of all such proceedings are not likely to have a material adverse effect on our consolidated financial position, results of operations or cash flows. 21

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS OVERVIEW Natural gas and oil prices, the offshore mobile rig count, and Deepwater construction activity are three of the primary indicators management uses to forecast the future performance of our business. Our construction services generally follow successful drilling activities by six to eighteen months on the OCS and twelve months or longer in the Deepwater arena. The level of drilling activity is related to both short- and long-term trends in natural gas and oil prices. Commodity prices declined significantly in the last half of 1998 and early 1999, resulting in the offshore mobile rig utilization rates dropping to approximately 70% in contrast to almost full utilization in 1997 and the first half of 1998. This trend began reversing in the second quarter of 1999 as oil prices reached their highest levels since the Gulf War and in early 2001 natural gas prices reached $10.00 per thousand cubic feet (Mcf), pushing the offshore mobile rig utilization rates back to virtually full utilization. However, a slowing world economy and record levels of natural gas in storage drove oil and gas prices down throughout 2001 with natural gas plunging to $2.00 per Mcf by the end of the year. Our primary leading indicator, the number of offshore mobile rigs contracted, is currently running at around 120 rigs employed in the Gulf of Mexico, compared to 180 last year at this time. The Deepwater GOM is principally an oil play with the size of the reservoirs resulting in significant lead times to first production. We are currently tracking 30 fields that will come into our service market, completion and production, principally in the years 2003 and 2004. We have aggressively moved to assemble a world-class fleet of seven DP vessels as we do not believe that there will be enough marine construction capacity to handle this demand. Product prices impact our natural gas and oil operations in several respects. We seek to acquire producing natural gas and oil properties that are generally in the later stages of their economic life. The potential abandonment liability is a significant consideration with respect to the offshore properties we have purchased to date. Although higher natural gas prices tend to reduce the number of mature properties available for sale, these higher prices typically contribute to improved operating results for ERT, such as in 2000 and the first half of 2001. In contrast, lower natural gas prices, as experienced in early 1999 and late 2001, typically contribute to lower operating results for ERT and a general increase in the number of mature properties available, as occurred during those periods. We have expanded the scope of our gas and oil operations by taking a working interest in Gunnison, a Deepwater development of Kerr-McGee Oil & Gas Corporation which has encountered significant reserves. We are also expanding our Deepwater Hub strategy by agreeing to participate in the ownership of the Marco Polo production facility. Vessel utilization is historically lower during the first quarter due to winter weather conditions in the Gulf. Accordingly, we plan our drydock inspections and other routine and preventive maintenance programs during this period. During the first quarter, a substantial number of our customers finalize capital budgets and solicit bids for construction projects. The bid and award process during the first two quarters typically leads to the commencement of construction activities during the second and third quarters. As a result, we have historically generated more than 50% (up to 65%) of our marine contracting revenues in the last six months of the year. Our operations can also be severely impacted by weather during the fourth quarter. Our salvage barge, which has a shallow draft, is particularly sensitive to adverse weather conditions, and its utilization rate tends to be lower during such periods. To minimize the impact of weather conditions on our operations and financial condition, we began operating DP vessels and expanded into the acquisition of oil and gas properties. The unique station-keeping ability offered by DP enables these vessels to operate throughout the winter months and in rough seas. Operation of natural gas and oil properties and production facilities tends to offset the impact of weather since the first and fourth quarters are typically periods of high demand and strong prices for natural gas. Due to this seasonality, full year results are not likely to be a direct multiple of any particular quarter or combination of quarters. CRITICAL ACCOUNTING POLICIES The results of operations and financial condition of the Company, as reflected in the accompanying financial statements and related footnotes, are subject to management's evaluation and interpretation of 25

business conditions, changing capital market conditions and other factors which could affect the ongoing viability of the Company's business segments and/or its customers. Management believes the most critical accounting policies in this regard are the estimation of revenue allowance on gross amounts billed and evaluation of recoverability of property and equipment and goodwill balances. These issues require management to make judgments that are subjective in nature, however, management is able to consider and assess a significant amount of historical data and current market data in arriving at reasonable estimates. Another area which requires management to make subjective judgments is that of revenue recognition. CDI's revenues are derived from billings under contracts (which are typically of short duration) that provide for either lump-sum turnkey charges or specific time, material and equipment charges which are billed in accordance with the terms of such contracts. The Company recognizes revenue as it is earned at estimated collectible amounts. Revenue on significant turnkey contracts is recognized on the percentage-of-completion method based on the ratio of costs incurred to total estimated costs at completion. Contract price and cost estimates are reviewed periodically as work progresses and adjustments are reflected in the period in which such estimates are revised. Provisions for estimated losses on such contracts are made in the period such losses are determined. ERT acquisitions of producing offshore properties are recorded at the value exchanged at closing together with an estimate of its proportionate share of the undiscounted decommissioning liability assumed in the purchase based upon its working interest ownership percentage. In estimating the decommissioning liability assumed in offshore property acquisitions, the Company performs detailed estimating procedures, including engineering studies. The Company follows the successful efforts method of accounting for its interests in natural gas and oil properties. Under the successful efforts method, the costs of successful wells and leases containing productive reserves are capitalized. Costs incurred to drill and equip development wells, including unsuccessful development wells, are capitalized. NEW ACCOUNTING PRONOUNCEMENTS In July 2001, the Financial Accounting Standards Board (FASB) issued Statement of Financial Accounting Standards (SFAS) No. 141, Business Combinations, which supersedes Accounting Principles Board (APB) Opinion No. 16, Business Combinations. SFAS 141 eliminates the pooling-of-interests method of accounting for business combinations and modifies the application of the purchase accounting method. The provisions of SFAS 141 were effective for transactions accounted for using the purchase method completed after June 30, 2001. The Company completed no business combination between June 30, 2001 and December 31, 2001. The Company did acquire 85% of Canyon Offshore, Inc. in January 2002 and accounted for the acquisition using the purchase method in accordance with SFAS 141. See further discussion below. In July 2001, the FASB also issued SFAS No. 142, Goodwill and Intangible Assets, which supersedes APB Opinion No. 17, Intangible Assets. SFAS 142 eliminates the current requirement to amortize goodwill and indefinite-lived intangible assets, addresses the amortization of intangible assets with a defined life and addresses the impairment testing and recognition for goodwill and intangible assets. SFAS 142, which is effective for 2002, will apply to goodwill and intangible assets arising from transactions completed before and after the statement's effective date. We believe adoption of this standard will have an immaterial effect on CDI's financial position and results of operations. In July 2001, the FASB released SFAS No. 143, Accounting for Asset Retirement Obligations, which is required to be adopted by the Company no later than January 1, 2003. SFAS No. 143 addresses the financial accounting and reporting obligations and retirement costs related to the retirement of tangible long-lived assets. The Company is currently reviewing the provisions of SFAS No. 143 to determine the standard's impact, if any, on its financial statements upon adoption. Among other things SFAS No. 143 will require oil and gas companies to reflect decommissioning liabilities on the face of the balance sheet, something ERT has done since inception on an undiscounted basis. In August 2001, the FASB issued SFAS No. 144, Accounting for the Impairment or Disposal of Long-Lived Assets, which is effective for the Company beginning January 1, 2002. SFAS No. 144 supersedes SFAS No. 121, Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of, and the accounting and reporting provisions relating to the disposal of a segment of a business of APB Opinion 26

No. 30. The Company believes that the adoption of SFAS No. 144 will not have a material impact on its financial position or results of operations. The following table sets forth for the periods presented average U.S. natural gas prices, our equivalent natural gas production, the average number of offshore rigs under contract in the Gulf, the number of platforms installed and removed in the Gulf and the vessel utilization rates for each of the major categories of our fleet.

During the second quarter of 1999, the Uncle John spent 30 days in drydock undergoing thruster work and inspections. During the second quarter of 2000, the Uncle John spent 47 days in drydock for engine replacement and inspections and the Witch Queen spent 41 days in drydock undergoing regulatory inspections. During the third quarter of 2000, these vessels were out for a combined 105 days for the same reasons. ITEM 7. RESULTS OF OPERATIONS COMPARISON OF YEAR ENDED DECEMBER 31, 2001 AND 2000 Revenues. During the year ended December 31, 2001, the Company's revenues increased 25% to $227.1 million compared to $181.0 million for the year ended December 31, 2000 with the Subsea and Salvage segment contributing all of the increase. Aquatica revenues increased 80% to $37.0 million for 2001 from $20.6 million in the prior year due, in part, to added capacity as a result of our acquisition of Professional Divers of New Orleans, Inc. in February 2001 and improved OCS activity. Revenues generated from our DP fleet increased 54% to $79.3 million during 2001 compared to $51.4 million in 2000 due mainly to vessel utilization improving from 56% during 2000 to 87%. This increased utility reflects improved CDI market share, an expansion in the scope of Deepwater services provided and expansion into other regions (Mexico and Trinidad). Natural Gas and Oil Production revenue for the year ended December 31, 2001 decreased 10% to $63.4 million from $70.8 million during the prior year due to a 10% decrease in production from 15.5 Bcfe in 2000 compared to 13.9 Bcfe during 2001. ERT received an average of $4.44 per Mcf for natural gas and $24.54 per Bbl for oil during 2001 compared to $4.04 per Mcf and $28.91 per Bbl in 2000. Oil and condensate represented 30% of ERT's revenues in 2001 versus 27% in 2000. Gross Profit. Gross profit of $66.9 million for the year ended December 31, 2001 was 21% better than the $55.4 million gross profit recorded in the prior year with Subsea and Salvage contracting gross profit 27

providing all of the increase and offsetting a $9.1 million decline in Natural Gas & Oil Production gross profit. Subsea and Salvage margins improved from 15% for the year ended December 31, 2000 to 22% during the year ended December 31, 2001 due mainly to the increase in utilization due to increased marine construction activity, even though we earned only 5% margins on $15 million of Nansen/Boomvang volume that was mostly pass-through revenue. Natural Gas and Oil Production gross profit decreased $9.1 million from $39.3 million in the year ended December 31, 2000 to $30.2 million for the year ended December 31, 2001 due mainly to the aforementioned 10% decline in production, higher amortization rates in 2001 than 2000 and $1.0 million of accounts receivable exposure related to the Enron bankruptcy. Selling and Administrative Expenses. Selling and administrative expenses were $21.3 million in 2001, which is relatively flat (3% increase) with the $20.8 million incurred during 2000. Given the increased revenues, this tight cost control provided a two point margin improvement (i.e., 9% margin for the year ended December 31, 2001 compared to 11% for the year ended December 31, 2000). Net Interest (Income) Expense and Other. The Company reported net interest expense and other of $1.3 million for the year ended December 31, 2001 in contrast to $554,000 for the prior year as average cash balances (net of MARAD financing) declined during 2001 as compared to 2000 due mainly to costs associated with construction of the Q4000 and the Intrepid conversion. Income Taxes. Income taxes increased to $15.5 million for the year ended December 31, 2001, compared to $11.6 million in the prior year due to increased profitability. Federal income taxes were provided at the statutory rate of 35% in 2001. However, our deduction of Q4000 construction costs as Research and Development expenditures for federal tax purposes resulted in CDI paying no federal income taxes in 2001 and 2000. Since the deduction of Q4000 construction costs affects financial and taxable income in different years, the entire 2001 and 2000 provisions for federal taxes were reflected as deferred income taxes. In addition, the balance sheet includes a $10.0 million income tax receivable as of December 31, 2000 which reflects our amending prior year tax returns to reflect the deduction of such costs (these tax refunds were received in January 2001). Net Income. Net income of $28.9 million for the year ended December 31, 2001 was $5.6 million, or 24%, more than 2000 as a result of factors described above. COMPARISON OF YEAR ENDED DECEMBER 31, 2000 AND 1999 Revenues. During the year ended December 31, 2000, our revenues increased 12% to $181.0 million compared to $161.0 million for the year ended December 31, 1999, with Natural Gas and Oil Production contributing all of the increase. Revenue for Subsea and Salvage decreased from $128.4 million to $110.2 million. Subsea and Salvage contracting revenues include almost $17.1 million of revenues from the addition of the DP vessel Cal Dive Aker Dove and the acquisition of the 55% of Aquatica not previously owned. Exclusive of these new assets, Subsea and Salvage contributed $35.3 million less in 2000 than it did in 1999, due primarily to the weak GOM construction market in 2000 and eight vessels being out of service during the first half of 2000 for a combined 416 days for U.S. Coast Guard (the Coast Guard or USCG) and American Bureau of Shipping (ABS) inspections and two major DP vessels being out of service a combined total of 105 days during the third quarter of 2000. This compares to three vessels being out of service for a combined 113 days during 1999. In addition, the 2000 salvage market was slower than anticipated as producers retained ownership to milk the last production out of mature fields and to take advantage of the high commodity prices. As a result, revenues from our barge operations (which include the subcontract of Horizon derrick and pipelay barges) were only $12.5 million during 2000 or two-thirds of the prior year. Margins also suffered as too many salvage contractors chased too little work. Natural Gas and Oil Production revenue for 2000 increased 118% to $70.8 million from $32.5 million during the prior year due to a 74% increase in production from 8.9 Bcfe to 15.5 Bcfe. Production grew as a result of the acquisition of interests in six offshore blocks from EEX Corporation during the first quarter as 28

well as additional production derived from 1999 property acquisitions (involving a total of 20 offshore blocks) and the 1999 well exploitation program. In addition, we realized an average gas price of $4.03 per Mcf equivalent in 2000, an increase of $1.68, or 71%, over 1999. Oil prices averaged over $29 per barrel and represented 27% of gas and oil revenues in 2000. Gross Profit. Gross profit of $55.4 million for 2000 was 49% better than the $37.3 million gross profit recorded in the comparable prior year period due mainly to the revenue improvement as well as an eight point improvement in margins (31% in 2000 versus 23% in the prior year). Subsea and Salvage margins declined from 20% for 1999 to 15% for 2000 due partly to the weak market and the additional vessels out of service for regulatory inspections and upgrades. While Aquatica margins remained at roughly the consolidated average of 30%, those of the larger vessels that work from 300 feet out into the Deepwater declined by seven percentage points from the prior year. The newly added Cal Dive Aker Dove represented more than half of the year-over-year decline in the gross profit generated by our DP fleet. The operating loss of this vessel was due to the low level of utilization in 2000 and to the sale/leaseback structure whereby financing cost was reported above the line as a charter cost. Natural Gas and Oil Production gross profit increased $27.4 million from $11.9 million in 1999 to $39.3 million for 2000 (and margins improved from 37% to 55%) due to the aforementioned production and commodity pricing improvements. Selling and Administrative Expenses. Selling and administrative expenses were $20.8 million in 2000, a 57% increase over the $13.2 million incurred in 1999 due mainly to improved operating results for ERT, whose incentive plan tracks its operating results ($3.1 million increase), and to the consolidation of Aquatica ($1.4 million increase). The remainder of the increase is due to the addition of personnel to the newly formed Well Operations Group to meet the anticipated demand for our services in the Deepwater market. Net Interest (Income) Expense and Other. We reported net interest expense and other of $554,000 for 2000 in contrast to $849,000 of net interest income for 1999 as average cash balances declined during 2000 as compared to 1999. This decrease was due mainly to the Company's capital program (Q4000 vessel construction) combined with the recording of goodwill amortization expense beginning in August 1999 upon acquiring the 55% of Aquatica, Inc. that we did not already own. Minority interest added back $866,000 in 2000 compared to $109,000 reduction in 1999 due to the losses recorded in 2000 by the Cal Dive Aker Dove, a vessel which was jointly owned with Aker Maritime. Income Taxes. Income taxes increased to $11.6 million for 2000, compared to $8.5 million in the prior year due to increased profitability. Federal income taxes were provided at 34% in 2000, slightly below the statutory rate of 35%. Net Income. Net income of $23.3 million for 2000 was $6.4 million, or 38% more than 1999 as a result of factors described above. Diluted earnings per share increased only 31% reflecting the additional shares issued to acquire Aquatica in the third quarter of 1999 and the shares sold in conjunction with the Secondary Offering (Green Shoe). LIQUIDITY AND CAPITAL RESOURCES The Company completed an initial public offering of common stock on July 7, 1997, with the net proceeds of approximately $39.5 million resulting in $15 million of cash on hand after paying off all debt outstanding. The following three years internally generated cash flow funded approximately $164 million of capital expenditures while enabling the Company to remain essentially debt free. During the third quarter of 2000 we closed the long-term MARAD financing for construction of the Q4000 and have drawn $99.5 million on this facility through December 31, 2001. In January 2002, the Maritime Administration agreed to expand the facility to $160 million to include the modifications to the vessel which had been approved during 2001. Through December 31, 2001, we have funded over $137 million of the newbuild vessel's $182 million budgeted construction costs. Significant internally generated cash flow during 2001, coupled with the collection of a $10 million tax refund enabled us to acquire the Mystic Viking (a 240 foot DP vessel), the Eclipse (a 370 foot DP vessel) and Professional Divers of New Orleans, Inc. (PDNO) while maintaining cash 29

balances of $37.1 million as of December 31, 2001. In January 2002, we acquired approximately 85% of Canyon Offshore, Inc. for cash of $51 million, the assumption of $5 million of net debt and 181,000 shares of CDI common stock (143,000 shares of which were purchased by the Company during the fourth quarter of 2001). As of February 28, 2001, we had $114.4 million of debt outstanding under the MARAD facility and $25.2 million of debt outstanding under our $60 million revolving credit facility. In addition, as of February 28, 2001, we (through a special purpose entity) had drawn $11.3 million on a project financing facility covering CDI's share of costs for the construction of the spar at Gunnison. The Company believes that internally-generated cash flow, borrowings under existing credit facilities and use of project financings along with other debt and equity alternatives will provide the necessary capital to achieve our planned growth. Operating Activities. Net cash provided by operating activities was $89.1 million during the year ended December 31, 2001, as compared to $53.7 million during 2000. This increase was due mainly to increased profitability and collection of a $10 million tax refund from the Internal Revenue Service (reflected in Changes in Income Taxes Receivable) relating to the deduction of Q4000 construction costs as research and development expenditures for federal tax purposes. Timing of accounts payable payments provided $22.3 million of the increase due mainly to expenses accrued at December 31, 2001 on the Nansen/Boomvang project which carries a large component of pass-through costs. This project also accounted for the significant increase in unbilled revenue at December 31, 2001 ($10.7 million versus $1.9 million at December 31, 2000), as the next scheduled invoicing milestone was achieved in January 2002. This was offset by a $20.3 million decrease in funding from accounts receivable collections during 2001 compared to 2000 as we have extended payment terms to Horizon Offshore. In addition, depreciation and amortization increased $3.8 million to $34.5 million for 2001 due mainly to the depreciation of newly acquired vessels in service. Net cash provided by operating activities was $53.7 million in 2000, as compared to $25.5 million in 1999. This increase was mainly due to increased profitability as well as $23.6 million of funding from the collection of accounts receivable during 2000 as we collected all amounts due on the EEX Cooper abandonment project (the largest contract in our history) during the first quarter. In addition, depreciation and amortization increased $10.1 million to $30.7 million for 2000 due mainly to ERT depletion associated with increased production levels. These increases, along with the aforementioned deferred tax increase, were partially offset by a $22.2 million reduction in the level of funding from accounts payable and accrued liabilities in 2000 compared to 1999. The 1999 levels increased primarily as a result of year-end accruals with respect to the Q4000 construction project and the EEX project. Investing Activities. Capital expenditures have consisted principally of strategic asset acquisitions related to the assembly of a fleet of DP vessels, construction of the Q4000, acquisition of Aquatica and PDNO, improvements to existing vessels and the acquisition of offshore natural gas and oil properties. We have consistently targeted the years 2002/2003 as the time when we expect to see a significant acceleration in Deepwater demand. As a result, we incurred $151.3 million of capital expenditures during 2001 compared to $95.1 million during 2000 and $77.4 million during 1999, a level which was over five times the prior year. Included in the $151.3 million of capital expenditures in 2001 was $53 million for the construction of the Q4000, $33 million for the conversion of the Intrepid, $40 million relating to the purchase of two DP vessels (the 240 foot by 52 foot Mystic Viking and the 370 foot by 67 foot Eclipse), and production partnering expenditures of $20 million for initial Gunnison development costs and the ERT 2001 Well Enhancement Program. In addition, in March 2001, CDI acquired substantially all of the assets of PDNO in exchange for $11.5 million. The assets purchased included the Sea Level 21 (a 165-foot four-point moored DSV renamed the Mr. Sonny), three utility vessels and associated diving equipment including two saturation diving systems. This acquisition was accounted for as a purchase with the acquisition price of $11.5 million being allocated to the assets acquired and liabilities assumed based upon their estimated fair values with the balance of the purchase price ($2.8 million) being recorded as excess of cost over net assets acquired (goodwill). Included in the $95.1 million of capital expenditures in 2000 was $61.0 million for the construction of the Q4000 and $8.5 million relating to the conversion of the Intrepid. ERT purchased working interests of 3% to 75% in four offshore blocks during 2001 in exchange for assumption of the pro-rata share of the decommissioning obligations. In addition, during the first quarter of 2001 ERT purchased a working interest of 55% in Vermilion 201 for $2.5 million from an investment 30

partnership composed of Company management and industry sources which had funded the drilling of a deep exploratory well. Also, during the first half of 2000, ERT acquired interests in six offshore blocks from EEX Corporation and agreed to operate the remaining EEX properties on the OCS. The acquired offshore blocks include working interests from 40% to 75% in five platforms, one caisson and 13 wells. ERT agreed to a purchase price of $4.9 million, assumed EEX Corporation's pro rata share of the abandonment obligation for the acquired interests and entered into a two-year contract to manage the remaining EEX operated properties. During the first four months of 1999, in four separate transactions, ERT acquired interests in 20 blocks in exchange for cash consideration, as well as assumption of the pro rata share of the related decommissioning liabilities. In connection with 2001, 2000 and 1999 offshore property acquisitions, ERT assumed net abandonment liabilities of approximately $3,100,000, $4,200,000 and $19,500,000, respectively. ERT production activities are regulated by the Federal government and require significant third-party involvement, such as refinery processing and pipeline transportation. We record revenue from our offshore properties net of royalties paid to the Minerals Management Service (MMS). Royalty fees paid totaled approximately $15.2 million, $11.7 million and $4 million for the years ended 2001, 2000 and 1999, respectively. In accordance with Federal regulations that require operators in the Gulf of Mexico to post an area wide bond of $3 million, the MMS has allowed the Company to fulfill such bonding requirements through an insurance policy. In April 2000, ERT acquired a 20% working interest in Gunnison, a Deepwater Gulf of Mexico prospect of Kerr-McGee Oil & Gas Corporation. Consistent with CDI's philosophy of avoiding exploratory risk, financing for the exploratory costs (initially estimated at $15 million) was provided by an investment partnership (OKCD Investments, Ltd.), the investors of which are CDI senior management, in exchange for a 25% revenue override of CDI's 20% working interest. CDI provided no guarantees to the investment partnership. At that time, the Board of Directors established three criteria to determine a commercial discovery and the commitment of Cal Dive funds: 75 million barrels (gross) of reserves, total development costs of $500 million consistent with 75 MBOE, and a CDI estimated shareholder return of no less than 12%. Kerr-McGee, the operator, drilled several exploration wells and sidetracks in 3,200 feet of water at Garden Banks 667, 668 and 669 (the Gunnison prospect) and encountered significant potential reserves resulting in the three criteria being achieved during 2001. The exploratory phase was expanded to ensure field delineation resulting in the investment partnership which assumed the exploratory risk funding $20 million of exploratory drilling costs, considerably above the initial $15 million estimate. With the sanctioning of a commercial discovery, the Company will fund its share of ongoing development and production costs estimated in a range of $100 million to $110 million ($15.8 million of which had been incurred by December 31, 2001) with over half of that for construction of the spar. CDI has received a commitment from a financial institution to provide construction funding for the spar, including an option for CDI to convert this loan facility into a long-term (20 year) leveraged lease after the spar is placed in service. See further discussion below. As part of the process of obtaining funding for the exploratory costs of the Gunnison prospect and Vermilion 201, several outside third parties were solicited. Management believes that the fund structure of these transactions was both consistent with the guidelines and at least as favorable to the Company and ERT as could have been obtained from the third parties. During each of the past three years ERT has sold its interests in certain fields as well as the platforms and a pipeline. An ERT operating policy provides for the sale of assets when the expected future revenue stream can be accelerated in a single transaction. The net result of these sales was to add two cents, four cents and seven cents to diluted earnings per share in the years 2001, 2000 and 1999, respectively. These sales were structured as Section 1031 "Like Kind" exchanges for tax purposes. Accordingly, the cash received was restricted to use for subsequent acquisitions of additional natural gas and oil properties. In June 2000, the DP DSV Balmoral Sea caught fire while dockside in New Orleans, LA as the vessel was being prepared to enter drydock for an extended period. The vessel was deemed a total loss by insurance underwriters. Her book value (approximately $7 million) was fully insured as were all salvage and removal costs. Payments from the insurance companies were received during the fourth quarter of 2000. 31

In December 1999, a Cal Dive-affiliated company (CAHT I) entered into a sale-leaseback of the Cal Dive Aker Dove. Our portion of the proceeds received totaled $20.0 million. The lease was accounted for as an operating lease. Effective April 1, 2001, Coflexip's acquisition of Aker enabled CDI to "put" its interest in CAHT I back to Aker in return for Aker assuming all of CDI's obligations and guarantees under the sale-leaseback. Financing Activities. We have financed seasonal operating requirements and capital expenditures with internally generated funds, borrowings under credit facilities, the sale of common stock and project financings. In August 2000, the Company closed a $138.5 million long-term financing for construction of the Q4000. This U.S. Government guaranteed financing is pursuant to Title XI of the Merchant Marine Act of 1936 which is administered by the Maritime Administration (MARAD Debt). In January 2002, the Maritime Administration agreed to expand the facility to $160 million to include the modifications to the vessel which had been approved during 2001. At the time the financing closed in 2000, the Company made an initial draw of $40.1 million toward construction costs. During 2001, the Company borrowed $59.5 million on this facility and expects to draw the remaining commitment during 2002. The MARAD Debt will be payable in equal semi- annual installments beginning six months after delivery of the newbuild Q4000 and maturing 25 years from such date. It is collateralized by the Q4000, with CDI guaranteeing 50% of the debt, and bears an interest rate which currently floats at a rate approximating AAA Commercial Paper yields plus 20 basis points (2.25% as of December 31, 2001). For a period up to two years from delivery of the vessel CDI has options to lock in a fixed rate. In accordance with the MARAD Debt agreements, CDI is required to comply with certain covenants and restrictions, including the maintenance of minimum net worth and debt-to-equity requirements. As of December 31, 2001, the Company was in compliance with these covenants. Since April 1997, the Company has had a revolving credit facility of $40 million available. The Company drew upon this facility only 134 days during the four years ended December 31, 2001 with maximum borrowing of $11.9 million. The Company had no outstanding balance under this facility as of December 31, 2001. In February 2002, the Company amended this facility, expanding the amount available to $60 million and extending the term three years. This facility is collateralized by accounts receivable and most of the remaining vessel fleet, bears interest at LIBOR plus 125-250 basis points depending on CDI leverage ratios and, among other restrictions, includes three financial covenants (cash flow leverage, minimum interest coverage and fixed charge coverage). In November 2001, ERT (with a corporate guarantee by CDI) entered into a five-year lease transaction with a special purpose entity owned by a third party to fund CDI's portion of the construction costs ($67 million) of the spar for the Gunnison field. This lease is expected to be accounted for as an operating lease upon completion of the construction, and includes an option for the Company to convert the lease into a long-term (20 year) leveraged lease after construction is completed. As of December 31, 2001, the special purpose entity had drawn down $5.6 million on this facility. Accrued interest cost on the outstanding balance is capitalized to the cost of the facility during construction and is payable monthly thereafter. The principal balance of $67 million is due at the end of five years if the long-term leverage lease option is not taken. The facility bears interest at LIBOR plus 225-300 basis points depending on CDI leverage ratios and includes, among other restrictions, three financial covenants (cash flow leverage, minimum interest coverage and debt to total book capitalization). The Company was in compliance with these covenants as of December 31, 2001. 32

The following table summarizes the Company's contractual cash obligations as of December 31, 2001 and the scheduled years in which the obligations are contractually due (in thousands):

In January 2002, CDI acquired approximately 85% of Canyon Offshore, Inc. (Canyon), a supplier of remotely operated vehicles (ROVs) and robotics to the offshore construction and telecommunications industries, in exchange for cash of $51 million, the assumption of $5 million of Canyon net debt and 181,000 shares of CDI common stock (143,000 shares of which were purchased by the Company during the fourth quarter of 2001 for $2.6 million). Cal Dive will purchase the remaining 15% at a price to be determined by Canyon's performance during the years 2002 through 2004, a portion of which could be compensation expense. The total purchase price is estimated to range from $66 million to $74 million. The acquisition will be accounted for as a purchase with the acquisition price being allocated to the assets acquired and liabilities assumed based upon their estimated fair values, with the excess being recorded as goodwill, which is initially estimated at approximately $40 million. In September 2000, CDI completed a Secondary stock offering with Coflexip selling its 7.4 million shares of common stock at $26.31 per share. The over-allotment option was exercised resulting in the Company issuing 609,936 shares of common stock and receiving net proceeds of $14.8 million. In October 2000, our Board of Directors declared a two-for-one split of CDI's common stock in the form of a 100% stock distribution on November 13, 2000 to all holders of record at the close of business on October 30, 2000. All share and per share data in these financial statements have been restated to reflect the stock split. The only other financing activity during 2001, 2000 and 1999 represents the exercise of employee stock options. Capital Commitments. Our Board of Directors has approved a capital budget for 2002 which includes $50 million for the completion of the Q4000 and Intrepid, $65 million for the purchase of Canyon Offshore and the addition of three new Quest ROV units, and approximately $30 million as the equity portion of the construction of the Marco Polo production facility. In addition, it is estimated that CDI will be required to fund $19 million for Gunnison development expenditures in addition to an estimated $34 million which will be funded by the project financing established for the construction of the spar. In December 2001, CDI signed a letter of intent to form a 50-50 venture with El Paso Energy Partners to construct, install and own a Deepwater production hub platform and associated facilities primarily for Anadarko Petroleum Corporation's Marco Polo field discovery at Green Canyon 608 in the Gulf of Mexico. CDI's share of the construction costs is estimated to be $100 million. CDI, along with El Paso, is currently negotiating project financing for this venture, terms of which would include a 30% equity component for CDI. In connection with our business strategy, we evaluate acquisition opportunities (including additional vessels as well as interests in offshore natural gas and oil properties). No such acquisitions are currently pending. ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK A variety of quantitative and qualitative factors affect the operations of the Company.

CAL DIVE INTERNATIONAL, INC., AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 1. ORGANIZATION Cal Dive International, Inc. (Cal Dive, CDI or the Company), headquartered in Houston, Texas, owns, staffs and operates twenty-two marine construction vessels and a derrick barge in the Gulf of Mexico. The Company provides a full range of services to offshore oil and gas exploration and production and pipeline companies, including underwater construction, well operations, maintenance and repair of pipelines and platforms, and salvage operations. Diving and vessel support services in the shallow water market are provided by Aquatica, Inc., a wholly-owned subsidiary based in Lafayette, Louisiana. In January 2002, the Company expanded its Deepwater services through acquisition of Canyon Offshore, Inc. See footnote 17. In September 1992, Cal Dive formed a wholly-owned subsidiary, Energy Resource Technology, Inc. (ERT), to purchase non-core producing offshore oil and gas properties and those which are in the later stages of their economic lives. ERT is a fully bonded offshore operator and, in conjunction with the acquisition of properties, assumes the responsibility to decommission the property in full compliance with all governmental regulations. CDI has expanded the scope of its gas and oil operations by taking a working interest in Gunnison, a Deepwater development of Kerr-McGee Oil & Gas Corporation which has encountered significant reserves. The company is expanding its Deepwater Hub strategy by agreeing to participate in the ownership of the Marco Polo production facility. 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES PRINCIPLES OF CONSOLIDATION The accompanying consolidated financial statements include the accounts of the Company and its subsidiaries. All significant intercompany accounts and transactions have been eliminated. GOODWILL Through the end of 2001, goodwill was amortized on the straight-line method over its estimated useful life. Accumulated amortization as of December 31, 2001 and 2000 was $1.9 million and $1.2 million, respectively. The Company continually evaluated whether subsequent events or circumstances had occurred which indicated that the remaining useful life of goodwill might warrant revision or that the remaining balance of goodwill might not be recoverable. Management believes that there have been no events or circumstances which warrant revision to the remaining useful life or which affect recoverability of goodwill. In July 2001, the Financial Accounting Standards Board (FASB) issued Statement of Financial Accounting Standards (SFAS) No. 141, Business Combinations, which supersedes Accounting Principles Board (APB) Opinion No. 16, Business Combinations. SFAS 141 eliminates the pooling-of-interests method of accounting for business combinations and modifies the application of the purchase accounting method. The provisions of SFAS 141 were effective for transactions accounted for using the purchase method completed after June 30, 2001. The Company had no business combination completed between June 30, 2001 and December 31, 2001. In July 2001, the FASB also issued SFAS No. 142, Goodwill and Intangible Assets, which supersedes APB Opinion No. 17, Intangible Assets. SFAS 142 eliminates the current requirement to amortize goodwill and indefinite-lived intangible assets, addresses the amortization of intangible assets with a defined life and addresses the impairment testing and recognition for goodwill and intangible assets. SFAS 142, which is effective for 2002, will apply to goodwill and intangible assets arising from transactions completed before and after the statement's effective date. The Company believes adoption of this standard will have an immaterial effect on CDI's financial position and results of operations. 40

CAL DIVE INTERNATIONAL, INC., AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) PROPERTY AND EQUIPMENT Property and equipment are recorded at cost. Depreciation is provided primarily on the straight-line method over the estimated useful lives of the assets. All of the Company's interests in natural gas and oil properties are located offshore in United States waters. The Company follows the successful efforts method of accounting for its interests in natural gas and oil properties. Under the successful efforts method, the costs of successful wells and leases containing productive reserves are capitalized. Costs incurred to drill and equip development wells, including unsuccessful development wells, are capitalized. ERT acquisitions of producing offshore properties are recorded at the value exchanged at closing together with an estimate of its proportionate share of the undiscounted decommissioning liability assumed in the purchase based upon its working interest ownership percentage. In estimating the decommissioning liability assumed in offshore property acquisitions, the Company performs detailed estimating procedures, including engineering studies. All capitalized costs are amortized on a unit-of-production basis (UOP) based on the estimated remaining oil and gas reserves. Properties are periodically assessed for impairment in value, with any impairment charged to expense. In July 2001, the FASB released SFAS No. 143, Accounting for Asset Retirement Obligations, which is required to be adopted by the Company no later than January 1, 2003. SFAS No. 143 addresses the financial accounting and reporting obligations and retirement costs related to the retirement of tangible long-lived assets. The Company is currently reviewing the provisions of SFAS No. 143 to determine the standard's impact, if any, on its financial statements upon adoption. Among other things SFAS No. 143 will require oil and gas companies to reflect decommissioning liabilities on the face of the balance sheet, something ERT has done since inception on an undiscounted basis. The following is a summary of the components of property and equipment (dollars in thousands):

ESTIMATED USEFUL LIFE 2001 2000 ----------- -------- -------- Construction in progress............................. N/A $221,916 $111,250 Vessels.............................................. 15 103,929 78,776 Offshore leases and equipment........................ UOP 72,157 60,679 Gunnison property under development.................. N/A 10,177 -- Machinery, equipment and leasehold improvements...... 5 15,563 15,397 -------- -------- Total property and equipment....................... $423,742 $266,102 ======== ========
In July 1999, the CDI Board of Directors approved the construction of the Q4000, a newbuild, ultra-deepwater multi-purpose vessel, for a total estimated cost of $150 million and, in June 2001, approved modification to the original construction contract increasing the total estimated costs to $182 million. Amounts incurred on this project and the conversion of the Intrepid pipelay vessel are included in Construction in Progress ($1.9 million of which is capitalized interest). The cost of repairs and maintenance of vessels and equipment is charged to operations as incurred, while the cost of improvements is capitalized. Total repair and maintenance charges were $8,501,000, $4,343,000 and $6,031,000 for the years ended December 31, 2001, 2000 and 1999, respectively. In August 2001, the FASB issued SFAS No. 144, Accounting for the Impairment or Disposal of Long-Lived Assets, which is effective for the Company beginning January 1, 2002. SFAS No. 144 supersedes SFAS No. 121, Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to Be Disposed Of, and the accounting and reporting provisions relating to the disposal of a segment of a business of APB Opinion 41

CAL DIVE INTERNATIONAL, INC., AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) No. 30. The Company believes that the adoption of SFAS No. 144 will not have a material impact on its financial position or results of operations. USE OF ESTIMATES The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. EARNINGS PER SHARE The Company computes and presents earnings per share in accordance with SFAS No. 128, Earnings Per Share. SFAS 128 requires the presentation of "basic" EPS and "diluted" EPS on the face of the statement of operations. Basic EPS is computed by dividing the net income available to common shareholders by the weighted-average shares of outstanding common stock. The calculation of diluted EPS is similar to basic EPS except that the denominator includes dilutive common stock equivalents, which were stock options, less the number of treasury shares assumed to be purchased from the proceeds with the exercise of stock options. REVENUE RECOGNITION The Company earns the majority of its subsea service and salvage contracting revenues during the summer and fall months. Revenues are derived from billings under contracts (which are typically of short duration) that provide for either lump-sum turnkey charges or specific time, material and equipment charges which are billed in accordance with the terms of such contracts. The Company recognizes revenue as it is earned at estimated collectible amounts. Revenue on significant turnkey contracts is recognized on the percentage-of-completion method based on the ratio of costs incurred to total estimated costs at completion. Contract price and cost estimates are reviewed periodically as work progresses and adjustments are reflected in the period in which such estimates are revised. Provisions for estimated losses on such contracts are made in the period such losses are determined. Unbilled revenue represents revenue attributable to work completed prior to year-end which has not yet been invoiced. All amounts included in unbilled revenue at December 31, 2001 are expected to be billed and collected within one year. REVENUE ALLOWANCE ON GROSS AMOUNTS BILLED The Company bills for work performed in accordance with the terms of the applicable contract. The gross amount of revenue billed will include not only the billing for the original amount quoted for a project but also include billings for services provided which the Company believes are outside the scope of the original quote. The Company establishes a revenue allowance for these additional billings based on its collections history if conditions warrant such a reserve. MAJOR CUSTOMERS AND CONCENTRATION OF CREDIT RISK The market for the Company's products and services is the offshore oil and gas industry. Oil and gas companies make capital expenditures on exploration, drilling and production operations offshore, the level of which is generally dependent on the prevailing view of the future oil and gas prices, which have been characterized by significant volatility in recent years. The Company's customers consist primarily of major, well-established oil and pipeline companies and independent oil and gas producers. The Company performs ongoing credit evaluations of its customers and provides allowances for probable credit losses when necessary. The percent of consolidated revenue of major customers was as follows: 2001 -- Horizon Offshore, Inc. (18%), Enron Corporation (10%); 2000 -- Enron Corporation (13%); and 1999 -- EEX Corporation (13%). 42

CAL DIVE INTERNATIONAL, INC., AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) In March 2001, CDI and Horizon Offshore, Inc. announced that the Alliance Agreement covering operation on the Outer Continental Shelf was extended for a three-year period. Principal features of the Alliance are that CDI provides Dive Support Vessel services behind Horizon pipelay barges while Horizon supplies pipelay, derrick barge and heavy lift capacity to Cal Dive. The Alliance was also expanded to include CDI providing the diving personnel working from Horizon barges, a service Horizon handled internally in 2000. During 2001 the Company also provided dynamically positioned vessels to support Horizon projects for Pemex in Mexican waters of the Gulf of Mexico. INCOME TAXES Deferred taxes are recognized for revenues and expenses reported in different years for financial statement purposes and income tax purposes in accordance with SFAS No. 109, Accounting for Income Taxes. The statement requires, among other things, the use of the liability method of computing deferred income taxes. The liability method is based on the amount of current and future taxes payable using tax rates and laws in effect at the balance sheet date. DEFERRED DRYDOCK CHARGES The Company accounts for regulatory (U.S. Coast Guard, American Bureau of Shipping and Det Norske Veritas) related drydock inspection and certification expenditures by capitalizing the related costs and amortizing them over the 30-month period between regulatory mandated drydock inspections and certification. During the years ended December 31, 2001, 2000 and 1999, drydock amortization expense was $3.1 million, $2.2 million and $1.7 million, respectively. This predominant industry practice provides appropriate matching of expenses with the period benefitted (i.e., certification to operate the vessel for a 30-month period between required drydock inspections). STATEMENT OF CASH FLOW INFORMATION The Company defines cash and cash equivalents as cash and all highly liquid financial instruments with original maturities of less than three months. During the years ended December 31, 2001, 2000 and 1999, the Company made cash payments for interest charges, net of interest capitalized, of $662,000, $-0- and $-0-, respectively, and made cash payments for federal income taxes of approximately $-0-, $1,800,000 and $4,075,000, respectively. RECLASSIFICATIONS Certain reclassifications were made to previously reported amounts in the consolidated financial statements and notes to make them consistent with the current presentation format. 3. ACQUISITION OF DEEPWATER VESSELS In May 2001, Cal Dive acquired a dynamically positioned (DP) marine construction vessel, the Mystic Viking (formerly the Bergen Viking). The 240 foot by 52 foot vessel is DP-2 class, similar to the Witch Queen. The Mystic Viking replaces the Balmoral Sea (lost during 2000) and the Cal Dive Aker Dove (Cal Dive's ownership was transferred to Aker effective April 1, 2001). In October 2001, Cal Dive announced the acquisition of another DP marine construction vessel, the Eclipse (formerly the C.S. Seaspread). The 370 foot by 67 foot vessel is a sister ship to Coflexip Stena Offshore's Constructor and EMC's Bar Protector. She was sold out of the energy services industry into the telecom cable sector in the early 1990s. Following delivery in the first quarter of 2002, her original marine construction features will be restored by installing a saturation diving system (salvaged from the Balmoral Sea), restoring the ballast system, and upgrading the DP system to DP-2 standards. The total cost of the two 43

CAL DIVE INTERNATIONAL, INC., AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) vessels acquired and related upgrades will approximate $40 million, the majority of which has been expended as of December 31, 2001. 4. OFFSHORE PROPERTY TRANSACTIONS ERT purchased working interests of 3% to 75% in four offshore blocks during 2001 in exchange for assumption of the pro-rata share of the decommissioning obligations. In addition, during 2001 ERT purchased a working interest of 55% in Vermilion 201 for $2.5 million (see footnote 5). In the first quarter of 2000, ERT acquired interests in six offshore blocks from EEX Corporation and agreed to operate the remaining EEX properties on the Outer Continental Shelf (OCS). The acquired offshore blocks include working interests from 40% to 75% in five platforms, one caisson and 13 wells. ERT agreed to a purchase price of $4.9 million and assumed EEX's prorated share of the abandonment obligation for the acquired interests, and entered into a two-year contract to manage the remaining EEX operated properties. Additionally, in April 2000, ERT acquired a 20% interest in Gunnison. See further discussion in footnote 5. During the first four months of 1999, in four separate transactions, ERT acquired interests in 20 blocks and interests in six blocks involving two separate fields in exchange for cash as well as assumption of the pro-rata share of the related decommissioning liabilities. In connection with 2001, 2000 and 1999 offshore property acquisitions, ERT assumed net abandonment liabilities estimated at approximately $3,100,000, $4,200,000, and $19,500,000 respectively. ERT production activities are regulated by the federal government and require significant third-party involvement, such as refinery processing and pipeline transportation. The Company records revenue from its offshore properties net of royalties paid to the Minerals Management Service (MMS). Royalty fees paid totaled approximately $15.2 million, $11.7 million and $4 million for the years ended 2001, 2000 and 1999, respectively. In accordance with federal regulations that require operators in the Gulf of Mexico to post an area wide bond of $3 million, the MMS has allowed the Company to fulfill such bonding requirements through an insurance policy. During each of the past three years ERT has sold its interests in certain fields as well as the platforms and a pipeline. An ERT operating policy provides for the sale of assets when the expected future revenue stream can be accelerated in a single transaction. The net result of these sales was to add two cents, four cents and seven cents to diluted earnings per share for the years ending December 31, 2001, 2000 and 1999, respectively. These sales were structured as Section 1031 "Like Kind" exchanges for tax purposes. Accordingly, the cash received was restricted to use for subsequent acquisitions of additional natural gas and oil properties. 5. RELATED PARTY TRANSACTIONS In April 2000, ERT acquired a 20% working interest in Gunnison, a Deepwater Gulf of Mexico prospect of Kerr-McGee Oil & Gas Corporation. Consistent with CDI's philosophy of avoiding exploratory risk, financing for the exploratory costs (initially estimated at $15 million) was provided by an investment partnership (OKCD Investments, Ltd.), the investors of which are CDI senior management, in exchange for a 25% revenue override of CDI's 20% working interest. CDI provided no guarantees to the investment partnership. At this time, the Board of Directors established three criteria to determine a commercial discovery and the commitment of Cal Dive funds: 75 million barrels (gross) of reserves, total development costs of $500 million consistent with 75 MBOE, and a CDI estimated shareholder return of no less than 12%. Kerr-McGee, the operator, drilled several exploration wells and sidetracks in 3,200 feet of water at Garden Banks 667, 668 and 669 (the Gunnison prospect) and encountered significant potential reserves resulting in the three criteria being achieved during 2001. The exploratory phase was expanded to ensure field delineation resulting in the investment partnership which assumed the exploratory risk funding over $20 million of exploratory drilling costs, considerably above the initial $15 million estimate. With the sanctioning of a commercial discovery, the Company will fund ongoing development and production costs. Cal Dive's share of 44

CAL DIVE INTERNATIONAL, INC., AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) such project development costs is estimated in a range of $100 million to $110 million ($15.8 million of which had been incurred by December 31, 2001) with over half of that for construction of the spar. CDI has received a commitment from a financial institution to provide a construction funding for the spar, including an option for CDI to convert this loan facility into a long-term (20 year) leveraged lease after the spar is placed in service. See footnote 10. During the fourth quarter of 2000 another investment partnership composed of Company management and industry sources funded the drilling of a deep exploratory well at ERT's Vermilion 201 field. Effective January 1, 2001, ERT acquired approximately 55% of this investment partnership's interest in the reserves discovered for $2.5 million. As part of the process of obtaining funding for the exploratory costs of the above projects, several outside third parties were solicited. Management believes that the structure of these transactions was both consistent with the guidelines and at least as favorable to the Company and ERT as could have been obtained from the third parties. 6. ACQUISITION OF PROFESSIONAL DIVERS OF NEW ORLEANS, INC. (PDNO) AND AQUATICA, INC. In March 2001, CDI acquired substantially all of the assets of Professional Divers of New Orleans, Inc. (PDNO) in exchange for $11.5 million. The assets purchased included the Sea Level 21 (a 165-foot four-point moored DSV renamed the Mr. Sonny), three utility vessels and associated diving equipment including two saturation diving systems. This acquisition was accounted for as a purchase with the acquisition price of $11.5 million being allocated to the assets acquired and liabilities assumed based upon their estimated fair values with the balance of the purchase price ($2.8 million) being recorded as excess of cost over net assets acquired (goodwill). In February 1998, CDI purchased a significant minority equity interest in Aquatica, Inc., a shallow water diving company. CDI accounted for this investment on the equity basis of accounting for financial reporting purposes. The related Shareholder Agreement provided that the remaining shares of Aquatica, Inc. could be converted into Cal Dive shares based on a formula which, among other things, valued the shares of Aquatica, Inc. Effective August 1, 1999, 1.4 million shares of common stock of Cal Dive were issued for all of the remaining common stock of Aquatica, Inc. pursuant to these terms. This acquisition was accounted for as a purchase with the acquisition price of $16.2 million being allocated to the assets acquired and liabilities assumed based upon their estimated fair values. The fair value of tangible assets acquired and liabilities assumed was $6.4 million and $2.2 million, respectively. The balance of the purchase price ($12 million) was recorded as excess of cost over net assets acquired (goodwill). Results of operations for Aquatica, Inc. are consolidated with those of Cal Dive for periods subsequent to August 1, 1999. 7. ACCRUED LIABILITIES Accrued liabilities consisted of the following (in thousands):

LONG-TERM DEBT In August 2000, the Company closed a $138.5 million long-term financing for construction of the Q4000. This U.S. Government guaranteed financing is pursuant to Title XI of the Merchant Marine Act of 1936 which is administered by the Maritime Administration ("MARAD Debt"). In January 2002, the Maritime Administration agreed to expand the facility to $160 million to include the modifications to the vessel which had been approved during 2001. At the time the financing closed in 2000, the Company made an initial draw of $40.1 million toward construction costs. During 2001, the Company borrowed $59.5 million on this facility and expects to draw the remaining commitment during 2002. The MARAD Debt will be payable in equal semi-annual installments beginning six months after delivery of the newbuild Q4000 and maturing 25 years from such date. It is collateralized by the Q4000, with CDI guaranteeing 50% of the debt, and bears an interest rate which currently floats at a rate approximating AAA Commercial Paper yields plus 20 basis points (2.25% as of December 31, 2001). For a period up to two years from delivery of the vessel CDI has options to lock in a fixed rate. In accordance with the MARAD Debt agreements, CDI is required to comply with certain covenants and restrictions, including the maintenance of minimum net worth and debt-to-equity requirements. As of December 31, 2001, the Company was in compliance with these covenants. Since April 1997, the Company has had a revolving credit facility of $40 million available. The Company drew upon this facility only 134 days during the past four years with maximum borrowing of $11.9 million. The Company had no outstanding balance under this facility as of December 31, 2001. In February 2002, the Company amended this facility, expanding the amount available to $60 million and extending the term three years. This facility is collateralized by accounts receivable and most of the remaining vessel fleet, bears interest at LIBOR plus 125-250 basis points depending on CDI leverage ratios and, among other restrictions, includes three financial covenants (cash flow leverage, minimum interest coverage and fixed charge coverage). As of February 18, 2002, the Company had drawn $22 million under this revolving credit facility. See project financing of Gunnison spar at footnote 10. 9. FEDERAL INCOME TAXES Federal income taxes have been provided based on the statutory rate of 35 percent adjusted for items which are allowed as deductions for federal income tax reporting purposes, but not for book purposes. The primary differences between the statutory rate and the Company's effective rate are as follows:

CDI effectively paid no federal income taxes in 2001 and 2000 due to the deduction of Q4000 construction costs as research and development for federal tax purposes. The Company paid $1.8 million of federal income taxes during 2000, but the amount was refunded in January 2001 upon completing our research and development analysis and filing for the refund. In addition, we filed amended tax returns for 1998 and 1999, deducting such costs, resulting in refunds of $8.2 million which were collected in January 2001. These amounts were reflected as Income Tax Receivable in the accompanying consolidated balance sheets as of December 31, 2000. 10. COMMITMENTS AND CONTINGENCIES: LEASE COMMITMENTS During 1999, CDI acquired an interest in Cal Dive Aker CAHT I, LLC (CAHT I), the company which owned the Cal Dive Aker Dove (a newbuild DP anchor handling and subsea construction vessel which commenced operations in September 1999) for a total of $18.9 million. CDI effectively owned 56% of CAHT I and, accordingly, results of operations of this company were consolidated in the accompanying financial statements with Aker's share being reflected as minority interest. In December, 1999 CAHT I entered into a sale-leaseback of the Cal Dive Aker Dove. Cal Dive's portion of the sale proceeds received totaled $20 million. The lease was accounted for as an operating lease. Effective April 1, 2001, Coflexip's acquisition of Aker enabled CDI to "put" its interest in CAHT I back to Aker in return for Aker assuming all of CDI's obligations and guarantees under the sale-leaseback. In November 2001, ERT (with a corporate guarantee by CDI) entered into a five-year lease transaction with a special purpose entity owned by a third party to fund CDI's portion of the construction costs ($67 million) of the spar for the Gunnison field. This lease is expected to be accounted for as an operating lease upon completion of the construction and includes an option for the Company to convert the lease into a long-term (20 year) leveraged lease after construction is completed. As of December 31, 2001, the special purpose entity had drawn down $5.6 million on this facility. Accrued interest cost on the outstanding balance is capitalized to the cost of the facility during construction and are payable monthly thereafter. The principal balance of $67 million is due at the end of five years if the long-term leverage lease option is not taken. The facility bears interest at LIBOR plus 225-300 basis points depending on CDI leverage ratios and includes, among other restrictions, three financial covenants (cash flow leverage, minimum interest coverage and debt to total book capitalization). The Company was in compliance with these covenants as of December 31, 2001. The Company occupies several facilities under noncancelable operating leases, with the more significant leases expiring in the years 2004 and 2007. Future minimum rentals under these leases are $2,380,000 at December 31, 2001 with $701,000 due in 2002, $669,000 in 2003, $605,000 in 2004, $135,000 in 2005, 47

CAL DIVE INTERNATIONAL, INC., AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) $135,000 in 2006 and $135,000 thereafter. Total rental expense under these operating leases was $779,000, $721,000 and $673,000 for the years ended December 31, 2001, 2000 and 1999, respectively. In December 2001, CDI signed a letter of intent to form a 50-50 venture with El Paso Energy Partners to construct, install and own a Deepwater production hub platform and associated facilities primarily for Anadarko Petroleum Corporation's Marco Polo field discovery at Green Canyon 608 in the Gulf of Mexico. CDI's share of the construction costs is estimated to be $100 million. CDI, along with El Paso, is currently negotiating project financing for this venture, terms of which would include a 30% equity component for CDI. INSURANCE The Company carries Hull and Increased Value insurance which provides coverage for physical damage to an agreed amount for each vessel. The deductibles are based on the value of the vessel with a maximum deductible of $500,000 on the Q4000. Other vessels carry deductibles between $100,000 and $350,000. The Company also carries Protection and Indemnity insurance which covers liabilities arising from the operation of the vessel and General Liability insurance which covers liabilities arising from construction operations. The deductible on both the P&I and General Liability is $100,000 per occurrence. Onshore employees are covered by Workers' Compensation. Offshore employees, including divers and tenders and marine crews, are covered by an Excess Maritime Employers Liability insurance policy which covers Jones Act exposures and includes a deductible of $50,000 per occurrence. In excess of the liability policies named above, the Company carries various layers of Umbrella Liability for total limits of $135,000,000 excess of primary for all vessels except the Q4000. Total limits on the Q4000 are $160,000,000 excess of primary. The Company's self insured retention on its medical and health benefits program for employees is $50,000 per claim. In June 2000, the DP DSV Balmoral Sea caught fire while dockside in New Orleans, LA as the vessel was being prepared to enter drydock for an extended period. The vessel was deemed a total loss by insurance underwriters. Her book value (approximately $7 million) was fully insured as were all salvage and removal costs. Payments from the insurance companies were received during the fourth quarter of 2000. The Company incurs workers' compensation claims in the normal course of business, which management believes are covered by insurance. The Company, its insurers and legal counsel analyze each claim for potential exposure and estimate the ultimate liability of each claim. Amounts accrued and receivable from insurance companies, above the applicable deductible limits, are reflected in other current assets in the consolidated balance sheet. Such amounts were $6,276,000 and $6,133,000 as of December 31, 2001 and 2000, respectively. See related accrued liabilities at footnote 7. The Company has not incurred any significant losses as a result of claims denied by its insurance carriers. LITIGATION The Company is involved in various routine legal proceedings primarily involving claims for personal injury under the General Maritime Laws of the United States and Jones Act as a result of alleged negligence. In addition, the Company from time to time incurs other claims, such as contract disputes, in the normal course of business. The Company believes that the outcome of all such proceedings would not have a material adverse effect on its consolidated financial position, results of operations or net cash flows. In 1998, the Company entered into a subcontract with Seacore Marine Contractors Limited to provide the Sea Sorceress for subsea excavation in Canada. Seacore was in turn contracted by Coflexip Stena Offshore Newfoundland Limited, a subsidiary of Coflexip ("CSO Nfl"), as representative of the consortium of companies contracted to perform services on the project. Due to difficulties with respect to the sea states and soil conditions the contract was terminated. Cal Dive provided Seacore a performance bond of $5 million with respect to the subcontract. No call has been made on this bond. Although CSO Nfl has alleged that the Sea Sorceress was unable to adequately perform the excavation work required under the subcontract, Seacore and 48

CAL DIVE INTERNATIONAL, INC., AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) the Company believe the contract was wrongfully terminated and are vigorously defending this claim and seeking damages in arbitration. In another commercial dispute, EEX Corporation sued Cal Dive and others alleging breach of fiduciary duty by a former EEX employee and damages resulting from certain construction and property acquisition agreements. Cal Dive has responded alleging EEX Corporation breached various provisions of the same contracts and is seeking a declaratory judgment that the defendants are not liable. Although such litigation has the potential of significant liability, the Company believes that the outcome of all such proceedings is not likely to have a material adverse effect on its consolidated financial position, results of operations or net cash flows. 11. EMPLOYEE BENEFIT PLANS DEFINED CONTRIBUTION PLAN The Company sponsors a defined contribution 401(k) retirement plan covering substantially all of its employees. The Company's contributions are in the form of cash and are determined annually as 50 percent of each employee's contribution up to 5 percent of the employee's salary. The Company's costs related to this plan totaled $595,000, $423,000 and $375,000 for the years ended December 31, 2001, 2000 and 1999, respectively. STOCK-BASED COMPENSATION PLANS During 2000, the Board of Directors approved a "Stock Option in Lieu of Salary Program" for the Company's Chief Executive Officer. Under the terms of the program, the participant may annually elect to receive non-qualified stock options (with an exercise price equal to the closing stock price on the date of grant) in lieu of cash compensation with respect to his base salary and any bonus earned under the annual incentive compensation program. The number of options granted is determined utilizing the Black-Scholes valuation model as of the date of grant with a risk premium included. The participant made such election for 2001 and 2000 resulting in a total of 180,000 and 115,000 options being granted during 2001 and 2000, respectively (which includes bonuses earned under the annual incentive compensation program in both years). During 1995, the Board of Directors and shareholders approved the 1995 Long-Term Incentive Plan (the Incentive Plan). Under the Incentive Plan, a maximum of 10% of the total shares of Common Stock issued and outstanding may be granted to key executives and selected employees who are likely to make a significant positive impact on the reported net income of the Company. The Incentive Plan is administered by a committee which determines, subject to approval of the Compensation Committee of the Board of Directors, the type of award to be made to each participant and sets forth in the related award agreement the terms, conditions and limitations applicable to each award. The committee may grant stock options, stock appreciation rights, or stock and cash awards. Options granted to employees under the Incentive Plan vest 20% per year for a five year period or 33% per year for a three year period, have a maximum exercise life of three, five or ten years and, subject to certain exceptions, are not transferable. Effective May 12, 1998, the Company adopted a qualified, non-compensatory Employee Stock Purchase Plan ("ESPP"), which allows employees to acquire shares of common stock through payroll deductions over a six month period. The purchase price is equal to 85 percent of the fair market value of the common stock on either the first or last day of the subscription period, whichever is lower. Purchases under the plan are limited to 10 percent of an employee's base salary. Under this plan 38,849, 25,391 and 22,476 shares of common stock were purchased in the open market at a weighted average share price of $22.22, $21.55 and $12.19 during 2001, 2000 and 1999, respectively. The above plans are accounted for using APB Opinion No. 25, and therefore no compensation expense is recorded. If SFAS Statement No. 123 had been used for the accounting of these plans, the Company's pro forma net income for 2001, 2000 and 1999 would have been $25,879,000, $21,665,000 and $16,218,000, 49

CAL DIVE INTERNATIONAL, INC., AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) respectively, and the Company's pro forma diluted earnings per share would have been $0.79, $0.67 and $0.53, respectively. These pro forma results exclude consideration of options granted prior to January 1, 1995, and therefore may not be representative of that to be expected in future years. The fair value of each option grant is estimated on the date of grant using the Black-Scholes option pricing model with the following weighted average assumptions used: expected dividend yields of 0 percent; expected lives ranging from three to ten years, risk-free interest rate assumed to be 5.5 percent in 1999, 5.0 percent in 2000 and 4.5 percent in 2001, and expected volatility to be 59 percent in 1999, 62 percent in 2000 and 61 percent in 2001. The fair value of shares issued under the ESPP was based on the 15% discount received by the employees. All of the options outstanding at December 31, 2001, have exercise prices as follows: 97,554 shares at $3.95, 579,000 at $4.75, 108,520 shares at $10.28, 211,668 shares at $18.00, 119,508 shares at $18.06, 129,000 shares at $19.63, 297,000 shares at $21.88 and 636,996 shares ranging from $6.50 to $26.75 and a weighted average remaining contractual life of 3.98 years. Options granted in 1999 include 287,278 shares issued in connection with the August 1, 1999 acquisition of Aquatica, Inc., which provided for conversion of Aquatica employee stock options into Cal Dive stock options at the same ratio which Aquatica common shares were converted into Cal Dive common shares. Options outstanding are as follows:

12. COMMON STOCK The Company's amended and restated Articles of Incorporation provide for authorized Common Stock of 120,000,000 shares with no par value per share. During the fourth quarter of 2001, CDI purchased 143,000 shares of its common stock for $2.6 million. In October 2000, the Board of Directors declared a two-for-one split of CDI's common stock in the form of a 100% stock distribution on November 13, 2000 to all holders of record at the close of business on October 30, 2000. All share and per share data in these financial statements have been restated to reflect the stock split. In September 2000, CDI completed a Secondary Stock Offering with Coflexip selling its 7.4 million shares of common stock at $26.31 per share. The over-allotment option was exercised resulting in the Company issuing 609,936 shares of common stock and receiving net proceeds of $14.8 million, and the Chief Executive Officer, selling 500,000 shares. 50

ESTIMATED QUANTITIES OF PROVED OIL AND GAS RESERVES Proved developed oil and gas reserve quantities are based on estimates prepared by Company engineers in accordance with guidelines established by the Securities and Exchange Commission. The Company's estimates of reserves at December 31, 2001, excluding Gunnison, have been reviewed by Miller and Lents, Ltd., independent petroleum engineers. Reserves attributable to Gunnison rely on the operator's estimate of proved reserves. The Company does not own a license to the geophysical data necessary for assessment of reserves and therefore, must rely on the operator's estimate of proved reserves. All of the Company's reserves are located in the United States. Proved reserves cannot be measured exactly because the estimation of 52

CAL DIVE INTERNATIONAL, INC., AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) reserves involves numerous judgmental determinations. Accordingly, reserve estimates must be continually revised as a result of new information obtained from drilling and production history, new geological and geophysical data and changes in economic conditions. As of December 31, 1999, 337,500 Bbls. of oil and 284,800 Mcf. of gas were undeveloped. As of December 31, 2000, -0- Bbls. of oil and -0- Mcf. of gas of the Company's proven reserves were undeveloped. As of December 31, 2001, 6,829,000 Bbls. of oil and 35,525,000 Mcf. of gas were undeveloped, all of which is attributable to Gunnison.

(a) Subject to all of the terms and conditions of this Agreement, Lenders agree, for so long as no Event of Default exists, to make Revolving Loans to Borrower from time to time, as requested by Borrower in accordance with the terms of Section 2.4, up to a maximum principal amount at any time outstanding equal to the Borrowing Base at such time.

maximum ceiling on Revolving Loans outstanding to Borrower at any time, subject to the provisions of Section 2.3. If the unpaid balance of the Revolving Loans should exceed the Borrowing Base or any other limitation set forth in this Agreement, such Revolving Loans shall nevertheless constitute Obligations that are secured by the Collateral and entitled to all the benefits thereof; provided, however, if such an overadvance occurs, Borrower shall immediately repay, without premium or penalty, Revolving Loans in an amount equal to such excess, along with accrued unpaid interest on the amount so repaid to the date of such repayment.

Insofar as Borrower may request and Fleet may be willing in its sole and absolute discretion to make Revolving Loans to Borrower at a time when the unpaid balance of Revolving Loans exceeds, or would exceed with the making of any such Revolving Loan, the Borrowing Base (any such Loan or Loans being herein referred to individually as an "Overadvance" and collectively as "Overadvances"), Fleet may make such Overadvances in amount not to exceed USD 1,000,000 at any time outstanding, and the Agent shall enter such Overadvances as debits in the Loan Account. All Overadvances shall be repaid on demand, shall be secured by the Collateral and shall bear interest as provided in this Agreement for Revolving Loans generally, and shall be subject to the terms of Section 2.9(d) hereof with respect to Agent Advances.

Section 2.8 Joint and Several Liability: Rights of Contribution. (a) Each Borrower states and acknowledges that: (i) pursuant to this Agreement, Borrowers desire to utilize their borrowing potential on a consolidated basis to the same extent possible if they were merged into a single corporate entity; (ii) it has determined that it will benefit specifically and materially from the advances of credit contemplated by this Agreement; (iii) it is both a condition precedent to the obligations of Lenders hereunder and a desire of the Borrowers that each Borrower execute and deliver to Agent and Lenders this Agreement; and (iv) Borrowers have requested and bargained for the structure and terms of and security for the advances contemplated by this Agreement. (b) Each Borrower hereby irrevocably and unconditionally: (i) agrees that it is jointly and severally liable to Lenders for the full and prompt payment of the Obligations and the performance by each Borrower of its obligations hereunder in accordance with the terms hereof; (ii) agrees to fully and promptly perform all of its obligations hereunder with respect to each advance of credit hereunder as if such advance had been made directly to it; and (iii) agrees as a primary obligation to indemnify Lenders on demand for and against any loss incurred by Lenders as a result of any of the obligations of any Borrower being or becoming void, voidable, unenforceable or ineffective for any reason whatsoever, whether or not known to Agent, Lenders or any Person, the amount of such loss being the amount which Lenders would otherwise have been entitled to recover from Borrower. It is the intent of each Borrower that the indebtedness, obligations and liability hereunder of no one of them be subject to challenge on any basis. Accordingly, as of the date hereof, the liability 29

of each Borrower under this Section 2.8, together with all of its other liabilities to all Persons as of the date hereof and as of any other date on which a transfer is deemed to occur by virtue of this Agreement, calculated in amount sufficient to pay its probable net liabilities on its existing Indebtedness as the same become absolute and matured ("Dated Liabilities") is, and is to be, less than the amount of the aggregate of a fair valuation of its property as of such corresponding date ("Dated Assets"). To this end, each Borrower under this Section 2.8, (i) grants to and recognizes in each other Borrower, ratably, rights of subrogation and contribution in the amount, if any, by which the Dated Assets of such Borrower, but for the aggregate of subrogation and contribution in its favor recognized herein, would exceed the Dated Liabilities of such Borrower or, as the case may be, (ii) acknowledges receipt of and recognizes its right to subrogation and contribution ratably from the other Borrower in the amount, if any, by which the Dated Liabilities of such Borrower, but for the aggregate of subrogation and contribution in its favor recognized herein, would exceed the Dated Assets of such Borrower under this Section 2.8. In recognizing the value of the Dated Assets and the Dated Liabilities, it is understood that Borrowers will recognize, to at least the same extent of their aggregate recognition of liabilities hereunder, their rights to subrogation and contribution hereunder. It is a material objective of this Section 2.8 that each Borrower recognizes rights to subrogation and contribution rather than be deemed to be insolvent (or in contemplation thereof) by reason of an arbitrary interpretation of its joint and several obligations hereunder. Section 2.9 Contribution of Lenders; Non-Ratable Loans (a) Agent's Election. Promptly after receipt of a Borrowing Notice pursuant to Section 2.4, the Agent shall elect, in its discretion, (i) to have the terms of Section 2.9(b) apply to such requested Borrowing, or (ii) to request Fleet to make a Non-Ratable Loan pursuant to the terms of Section 2.9(c) in the amount of the requested Borrowing; provided, however that if Fleet declines in its sole discretion to make a Non-Ratable Loan pursuant to Section 2.9(c) the Agent shall elect to have the terms of Section 2.9(b) apply to such requested Borrowing. (b) Making of Revolving Loans. (i) In the event that the Agent shall elect to have the terms of this Section 2.9(b) apply to a requested Borrowing as described in Section 2.4, then promptly after receipt of a Borrowing Notice, the Agent shall notify the Lenders by telecopy, telephone, or other similar form of transmission, of the requested Borrowing. Each Lender shall make the amount of such Lender's Pro Rata Share of the requested Borrowing available to the Agent in immediately available funds, to such account of the Agent as the Agent may designate, not later than 2:00 p.m., (Dallas, Texas time) on the Funding Date applicable thereto. After the Agent's receipt of the proceeds of such Revolving Loans, upon satisfaction of the applicable conditions precedent set forth in Article 9, the Agent shall make the proceeds of such Revolving Loans available to the Borrower on the applicable Funding Date by transferring same day funds equal to the proceeds of such Revolving Loans received by the Agent to the account designated pursuant 30

to Section 2.4 or disbursing such funds in such other manner as the Borrower may direct to the Agent. (ii) Unless the Agent receives notice from a Lender at least one Business Day prior to the date of a requested Borrowing, that such Lender will not make available its Pro Rata Share of such Borrowing, the Agent may assume that each Lender has made such amount available to the Agent in immediately available funds on the Funding Date and the Agent may (but shall not be required) to make available to the Borrower on such date a corresponding amount. If and to the extent a Lender has not made such amounts available to the Agent, and the Agent has made the Borrowing available to the Borrower, such Lender shall on the Business Day following such Funding Date make such amount available to the Agent, together with interest at the Base Rate for each day during such period. A notice by the Agent submitted to any Lender with respect to such amounts owing under this subsection shall be conclusive, absent manifest error. If such amount is not made available to the Agent on the Business Day following the Funding Date, the Agent will notify the Borrower of such failure and, upon demand by the Agent, the Borrower will pay such amount to the Agent for Agent's account, together with interest for each day elapsed since the Funding Date at the interest rate then applicable to Revolving Loans. The failure of a Lender to make its Pro Rata Share of a Borrowing available on a Funding Date (a "Defaulting Lender") shall not relieve any other Lender of its obligation to make its Pro Rata Share of such Borrowing on the Funding Date, but neither the Agent nor any Lender shall be responsible for the failure of any other Lender to make its Pro Rata Share of such Borrowing available on such Funding Date. (iii) The Agent shall not be obligated to transfer to a Defaulting Lender any payments made by any Borrower to the Agent for the Defaulting Lender's benefit; nor shall a Defaulting Lender be entitled to the sharing of any payments hereunder. Amounts payable to a Defaulting Lender shall instead be paid to or retained by the Agent. The Agent may hold and, in its discretion, re-lend to the Borrower the amount of all such payments received or retained by it for the account of the Defaulting Lender. Any amounts so re-lent to the Borrower shall bear interest at the rate applicable to Base Rate Loans and for all other purposes of this Agreement shall be treated as Revolving Loans; provided, however, that for purposes of voting or consenting to matters with respect to the Loan Documents and determining a Lender's Pro Rata Share, such Defaulting Lender shall be deemed not to be a "Lender". Until a Defaulting Lender cures its failure to fund its Pro Rata Share of any Borrowing (A) such Defaulting Lender shall not be entitled to any portion of the unused commitment fee set forth in Section 3.1(f) and (B) such fee shall accrue in favor of the Lenders which have funded their respective Pro Rata Shares of such requested Borrowing land shall be allocated among such performing Lenders ratably based upon their relative Commitments. This Section shall remain 31

effective with respect to such Lender until such time as the Defaulting Lender shall no longer be in default of any of its obligations under this Agreement. The terms of this Section shall not be construed to increase or otherwise affect the Commitment of any Lender, or relieve or excuse the performance by Borrower of its duties and obligations hereunder. (c) Making of Non-Ratable Loans. (i) In the event the Agent shall elect, with the consent of Fleet, to have the terms of this Section 2.9(c) apply to a requested Borrowing, Fleet shall make a Revolving Loan in the amount of such Borrowing (any such Revolving Loan made solely by Fleet pursuant to this Section 2.9(c) being referred to as a "Non-Ratable Loan" and such Revolving Loans being referred to collectively as "Non-Ratable Loan") available to the Borrower on the Funding Date applicable thereto by transferring same day funds to the account of such Borrower, designated pursuant to Section 2.4. Each Non-Ratable Loan is a Revolving Loan hereunder and shall be subject to all the terms and conditions applicable to other Revolving Loans except that all payments thereon shall be payable to Fleet solely for its own account (and for the account of the holder of any participation interest with respect to such Revolving Loan). The Agent shall not request Fleet to make any Non-Ratable Loan if (A) the Agent shall have received written notice from any Lender that one or more of the applicable conditions precedent set forth in Article 9 will not be satisfied on the requested Funding Date for the applicable Borrowing, or (B) the requested Borrowing would exceed the Revolving Credit Commitment on such Funding Date. Fleet shall not otherwise be required to determine whether the applicable conditions precedent set forth in Article 9 have been satisfied or the requested Borrowing would exceed the Revolving Credit Commitment on the Funding Date applicable thereto prior to making, in its sole discretion, any Non-Ratable Loan. (ii) The Non-Ratable Loans shall be secured by the Collateral, shall constitute Revolving Loans and Obligations hereunder, and shall bear interest at the rate applicable to the Revolving Loans from time to time. (d) Agent Advances. (i) Subject to the limitations set forth in the provisos contained in this Section 2.9(d), the Agent is hereby authorized by the Borrowers and the Lenders, from time to time in the Agent's sole discretion, (A) after the occurrence of a Default or an Event of Default, or (B) at any time that any of the other applicable conditions precedent set forth in Article 9 have not been satisfied, to make Base Rate Loans to the Borrower on behalf of the Lenders which the Agent, in its reasonable business judgment, deems necessary or desirable (1) to preserve or protect the Collateral or any portion thereof, (2) to enhance the likelihood of, or maximize the amount 32

of, repayment of the Loans and other Obligations, or (3) to pay any other amount chargeable to the Borrower pursuant to the terms of this Agreement, including costs, fees, and expenses as described in Section 12.4 (any of the advances described in this Section 2.9(d) being hereinafter referred to as "Agent Advances"); provided that the Majority Lenders may at any time revoke the Agent's authorization contained in this Section 2.9(d) to make Agent Advances, any such revocation to be in writing and to become effective prospectively upon the Agent's receipt thereof; (ii) The Agent Advances shall be repayable on demand and secured by the Collateral, shall constitute Revolving Loans and Obligations hereunder, and shall bear interest at the rate applicable to Base Rate Loans from time to time. The Agent shall notify the Borrower and each Lender in writing of each such Agent Advance; provided that the failure of the Agent to provide any such notice to the Borrower or any Lender shall not affect the Borrower's liability for or obligation to repay such Agent Advances or result in any liability or constitute the breach of any duty or obligation of the Agent hereunder. (e) Settlement. Except as may be specifically provided otherwise by this Section 2.9, it is agreed that each Lender's funded portion of the Revolving Loans is intended by the Lenders to be equal at all times to such Lender's Pro Rata Share of the outstanding Revolving Loans. Notwithstanding such agreement, the Agent, Fleet, and the other Lenders agree (which agreement shall not be for the benefit of or enforceable by the Borrowers) that in order to facilitate the administration of this Agreement and the other Loan Documents, settlement among them as to the Revolving Loans, the Non-Ratable, Loans, and the Agent Advances shall take place on a periodic basis in accordance with the following provisions: (i) The Agent shall request settlement (a "Settlement") with the Lenders on at least a weekly basis, or on a more frequent basis if so determined by the Agent, (A) on behalf of Fleet, with respect to each outstanding Non-Ratable Loan, (B) for itself, with respect to each Agent Advance, and (C) with respect to collections received, in each case, by notifying the Lenders of such requested Settlement by telecopy, telephone, or other similar form of transmission, of such requested Settlement, no later than 11:00 a.m. (Dallas, Texas time) on the date of such requested Settlement (the "Settlement Date"), each Lender (other than Fleet, in the case of Non-Ratable Loans, and the Agent, in the case of Agent Advances) shall make the amount of such Lender's Pro Rata Share of the outstanding principal amount of the Non-Ratable Loans and Agent Advances with respect to which Settlement is requested available to the Agent, to such account of the Agent as the Agent may designate, not later than 2:00 p.m. (Dallas, Texas time), on the Settlement Date applicable thereto, which may occur before or after the occurrence or during the continuation of a Default or an Event of Default and whether or not the applicable conditions precedent 33

set forth in Article 9 have then been satisfied. Such amounts made available to the Agent shall be applied against the amounts of the applicable Non-Ratable Loan or Agent Advance and, together with the portion of such Non-Ratable Loan or Agent Advance representing Fleet's Pro Rata Share thereof, shall constitute Revolving Loans of the Lenders, respectively. If any such amount is not made available to the Agent by any Lender on the Settlement Date applicable thereto, the Agent shall be entitled to recover such amount on demand from such Lender together with interest thereon at the Base Rate for the first three (3) days from and after the Settlement Date and thereafter at the Interest Rate then applicable to the Revolving Loans. (ii) Notwithstanding the foregoing, not more than one (1) Business Day after demand is made by the Agent (whether before or after the occurrence of a Default or an Event of Default and regardless of whether the Agent has requested a Settlement with respect to a Non-Ratable Loan or Agent Advance), each other Lender (A) shall irrevocably and unconditionally purchase and receive from Fleet or the Agent, as applicable, without recourse or warranty, an undivided interest and participation in such Non-Ratable Loan or Agent Advance equal to such Lender's Pro Rata Share of such Non-Ratable Loan or Agent Advance and (B) if Settlement has not previously occurred with respect to such Non-Ratable Loans or Agent Advances, upon demand by Fleet or the Agent, as applicable, shall pay to Fleet or the Agent, as applicable, as the purchase price of such participation an amount equal to one-hundred percent (100%) of such Lender's Pro Rata Share of such Non-Ratable Loans or Agent Advances. If such amount is not in fact made available to the Agent by any Lender, the Agent shall be entitled to recover such amount on demand from such Lender together with interest thereon at the interest rate then applicable to Base Rate Loans. (iii) From and after the date, if any, on which any Lender purchases an undivided interest and participation in any Non-Ratable Loan or Agent Advance pursuant to clause (ii) preceding, the Agent shall promptly distribute to such Lender at such address as such Lender may request in writing, such Lender's Pro Rata Share of all payments of principal and interest and all proceeds of Collateral received by the Agent in respect of such Non-Ratable Loan or Agent Advance. (iv) Between Settlement Dates, the Agent, to the extent no Agent Advances or Non-Ratable Loans are outstanding, may pay over to Fleet any payments received by the Agent, which in accordance with the terms of this Agreement would be applied to the reduction of the Revolving Loans, for application to Fleet's Revolving Loans. If, as of any Settlement Date, collections received since the then immediately preceding Settlement Date have been applied to Fleet's Revolving Loans (other than to Non-Ratable Loans or Agent Advances in which such Lender has not yet funded its 34

purchase of a participation pursuant to Section 2.9(d)(ii)), as provided for in the previous sentence, Fleet shall pay to the Agent for the accounts of the Lenders, to be applied to the outstanding Revolving Loans of such Lenders, an amount such that each Lender shall, upon receipt of such amount, have, as of such Settlement Date, its Pro Rata Share of the Revolving Loans. During the period between Settlement Dates, Fleet with respect to Non-Ratable Loans, the Agent with respect to Agent Advances, and each Lender with respect to the Revolving Loans other than Non-Ratable Loans and Agent Advances, shall be entitled to interest at the applicable rate or rates payable under this Agreement on the actual average daily amount of funds employed by Fleet, the Agent and the other Lenders. (f) Notation. The Agent shall record on its books the principal amount of the Revolving Loans owing to each Lender, including the Non-Ratable Loans owing to Fleet, and the Agent Advances owing to the Agent, from time to time. In addition, each Lender is authorized, at such Lender's option, to note the date and amount of each repayment or prepayment of principal of such Lender's Revolving Loans in its books and records, including computer records, such books and records constituting presumptive evidence, absent manifest error, of the accuracy of the information contained therein. (g) Lenders' Failure to Perform. All Revolving Loans (other than Non-Ratable Loans and Agent Advances) shall be made by the Lenders simultaneously and in accordance with their Pro Rata Shares. It is understood that (i) no Lender shall be responsible for any failure by any other Lender to perform its obligation to make any Revolving Loans hereunder, nor shall any commitment of any Lender be increased or decreased as a result of any failure by any other Lender to perform its obligation to make any Revolving Loans hereunder, (ii) no failure by any Lender to perform its obligation to make any Revolving Loans hereunder shall excuse any other Lender from its obligation to make any Revolving Loans hereunder, and (iii) the obligations of each Lender hereunder shall be several, not joint and several. ARTICLE 3. INTEREST, FEES, TERM, REDUCTION AND REPAYMENT Section 3.1 Interest, Fees and Charges. (a) Interest. Outstanding principal on the Loans shall bear interest at the option of Borrower (subject to the terms and conditions herein) at either the Base Rate or LIBOR Rate, calculated daily, at the following rates per annum (individually called, as applicable, an "Applicable Annual Rate"): (i) Existing LIBOR Loans. Each LIBOR Loan outstanding on the date of this Agreement shall bear interest at a rate per annum equal to the existing Applicable Annual Rate. 35

(ii) New LIBOR Loans. Each LIBOR Loan drawn after the Closing Date shall bear interest at a rate per annum equal to the LIBOR Rate plus the Applicable Margin Amount. (iii) Base Rate Loans. The Base Rate Loans shall bear interest at a fluctuating rate per annum equal to the Base Rate plus the Applicable Margin Amount. The interest rate applicable to Base Rate Loans shall be increased or decreased, as the case may be, by an amount equal to any increase or decrease in the Base Rate, with such adjustments to be effective as of the opening of business on the day that any such change in the Base Rate becomes effective. The Base Rate in effect on the date hereof shall be the Base Rate effective as of the opening of business on the date hereof, but if this Agreement is executed on a day that is not a Business Day, the Base Rate in effect on the date hereof shall be the Base Rate effective as of the opening of business on the last Business Day immediately preceding the date hereof. Interest on the Loans shall be calculated daily, based on the actual days elapsed over a three hundred-sixty (360) day year. Further, for the purpose of computing interest, all items of payment received by Lenders shall be applied by Lenders (subject to final payment of all drafts and other items received in form other than immediately available funds) against the Obligations on the day of receipt. The determination of when a payment is received by Lenders will be made in accordance with Section 3.6. (b) Default Rate of Interest. Upon and after the occurrence of an Event of Default, and during the continuation thereof, the principal amount of the Loans and other Obligations shall bear interest, calculated daily (computed on the actual days elapsed over a three hundred-sixty (360) day year), at two percent (2.00%) above the Base Rate or other applicable rate of interest (a "Default Rate"). (c) Maximum Rate of Interest. Notwithstanding anything to the contrary in this Agreement or otherwise, (i) if at any time the amount of interest computed on the basis of an Applicable Annual Rate or a Default Rate would exceed the amount of such interest computed upon the basis of the maximum rate of interest permitted by applicable state or federal law in effect from time to time hereafter (the "Maximum Legal Rate"), the interest payable under this Agreement shall be computed upon the basis of the Maximum Legal Rate, but any subsequent reduction in such Applicable Annual Rate or Default Rate, as applicable, shall not reduce such interest thereafter payable hereunder below the amount computed on the basis of the Maximum Legal Rate until the aggregate amount of such interest accrued and payable under this Agreement equals the total amount of interest which would have accrued if such interest had been at all times computed solely on the basis of an Applicable Annual Rate or Default Rate, as applicable; and (ii) unless preempted by federal law, an Applicable Annual Rate or Default Rate, as applicable, from time to time in effect hereunder may not exceed the applicable indicated rate ceiling as defined in the Texas Finance Code, (and as the same may be incorporated by reference in other Texas statutes), but otherwise without limitation, that rate based upon the "weekly rate ceiling" and calculated after taking into account any and all relevant fees, payments, and other charges in 36

respect of the Loan which are deemed to be interest under applicable law. If the applicable state or federal law is amended in the future to allow a greater rate of interest to be charged under this Agreement than is presently allowed by applicable state or federal law, then the limitation of interest hereunder shall be increased to the maximum rate of interest allowed by applicable state or federal law as amended, which increase shall be effective hereunder on the effective date of such amendment, and all interest charges owing to Lender by reason thereof shall be payable upon demand. (d) Excess Interest. No agreements, conditions, provisions or stipulations contained in this Agreement or any other instrument, document or agreement between Borrower, Agent and Lenders or default of Borrower, or the exercise by Agent or Lenders of the right to accelerate the payment of the maturity of principal and interest, or to exercise any option whatsoever contained in this Agreement or any other Loan Document, or the arising of any contingency whatsoever, shall entitle Lenders to contract for, charge, or receive, in any event, interest exceeding the Maximum Legal Rate. In no event shall Borrower be obligated to pay interest exceeding such Maximum Legal Rate and all agreements, conditions or stipulations, if any, which may in any event or contingency whatsoever operate to bind, obligate or compel Borrower to pay a rate of interest exceeding the Maximum Legal Rate, shall be without binding force or effect, at law or in equity, to the extent only of the excess of interest over such Maximum Legal Rate. In the event any interest is contracted for, charged or received in excess of the Maximum Legal Rate ("Excess"), Borrower acknowledges and stipulates that any such contract, charge, or receipt shall be the result of an accident and bona fide error, and that any Excess received by Lenders shall be applied, first, to reduce the principal then unpaid hereunder; second, to reduce the other Obligations; and third, returned to Borrower, it being the intention of the parties hereto not to enter at any time into a usurious or otherwise illegal relationship. Borrower recognizes that, with fluctuations in the Base Rate or the LIBOR Rate and the Maximum Legal Rate, such a result could inadvertently occur. By the execution of this Agreement, Borrower covenants that (i) the credit or return of any Excess shall constitute the acceptance by Borrower of such Excess, and (ii) Borrower shall not seek or pursue any other remedy, legal or equitable, against Lenders, based in whole or in part upon contracting for, charging or receiving of any interest in excess of the maximum authorized by applicable law. For the purpose of determining whether or not any Excess has been contracted for, charged or received by Lenders, all interest at any time contracted for, charged or received by Lenders in connection with this Agreement shall be amortized, prorated, allocated and spread in equal parts during the entire term of this Agreement. (e) Incorporation by this Reference. The provisions of Section 3.1(d) shall be deemed to be incorporated into every document or communication relating to the Obligations which sets forth or prescribes any account, right or claim or alleged account, right or claim of Lenders with respect to Borrower (or any other obligor in respect of Obligations), whether or not any provision of this Section 3.1 is referred to therein. All such documents and communications and all figures set 37

forth therein shall, for the sole purpose of computing the extent of the Obligations and obligations of the Borrowers (or other obligor) asserted by Agent or Lenders thereunder, be automatically re-computed by any Borrower or obligor, and by any court considering the same, to give effect to the adjustments or credits required by Section 3.1(d). (f) Unused Commitment Fee. Borrower agrees to pay to Agent for distribution to Lenders a monthly unused commitment fee equal to 0.375% per annum multiplied by the amount by which the Total Commitment exceeds the Average Monthly Loan Balance; provided, however, that if the Total Commitment exceeds the Average Monthly Loan Balance by $50,000,000 or more at any time during the first two (2) years following the Closing Date the fee shall be increased to 0.50% per annum for such period. Such unused commitment fee shall be payable (i) on the Closing Date, and (ii) monthly in arrears on the first day of each calendar month after the Closing Date. (g) Closing Fees. Borrower shall pay to Agent on the Closing Date for distribution to the Lenders a closing fee of $225,000 and an underwriting fee to the Agent as provided in the letter agreement between Borrower and Agent dated February ___, 2002. (h) Agency Fee. Borrower shall pay to Agent on the Closing Date and on each anniversary of the Closing Date during the term of this Agreement an agency fee of Twenty Thousand Dollars ($20,000). (i) Capital Adequacy Charge. In the event that a Lender shall have determined in good faith that the adoption of any law, rule or regulation regarding capital adequacy, or any change therein or in the interpretation or application thereof or compliance by such Lender with any request or directive regarding capital adequacy (whether or not having the force of law) from any central bank or governmental authority, does or shall have the effect of reducing the rate of return on such Lender's capital as a consequence of its obligations hereunder to a level below that which such Lender could have achieved but for such adoption, change or compliance (taking into consideration such Lender's policies with respect to capital adequacy) by an amount deemed- by such Lender, in its sole discretion, to be material, then from time to time, after submission by such Lender to Borrower of a certificate certifying the amount by which such rate of return is actually reduced with respect to this transaction, together with the calculation and a written demand therefor, Borrower shall promptly pay to such Lender such additional amount or amounts as will compensate such Lender for such reduction; provided, that, such Lender's other debtors are required to reimburse such Lender for the same type of reduction. The certificate of such Lender claiming entitlement to payment as set forth above shall be conclusive in the absence of manifest error. Such certificate shall set forth the nature of the occurrence giving rise to such payment, the additional amount or amounts to be paid to such Lender, and the method by which such amounts were determined. In determining such amount, a Lender may use any reasonable averaging and attribution method, so 38

long as it accurately reflects the reduction. A Lender claiming amounts under this Section 3.1(i) agrees to provide Borrower such additional information with respect thereto upon request. (j) Letter of Credit: LC Guaranty Fees. As additional consideration for the Issuing Bank's issuing its Letters of Credit for Borrower's account or for issuing its LC Guaranties at Borrower's request pursuant to Section 2.4, Borrower agrees to pay to the Issuing Bank, in addition to the Issuing Bank's costs and expenses incurred in issuing such Letters of Credit and LC Guaranties, fees equal to the Applicable Margin for LIBOR Loans (equal to the face amount of each Letter of Credit and LC Guaranty) times the face amount of each Letter of Credit and LC Guaranty, which fee shall be deemed fully earned upon issuance of each such Letter of Credit or LC Guaranty, and shall be due and payable in equal monthly installments beginning on the first Business Day of the month following the date of issuance of such Letter of Credit or LC Guaranty and continuing on the first Business Day of each month thereafter during the term thereof. No fee payable by Borrower to the Issuing Bank under this Section 3.1(j) shall be subject to rebate or proration upon the termination of this Agreement for any reason. Section 3.2 Additional Provisions Regarding LIBOR Loans. (a) Borrower may select a LIBOR Rate with respect to all or any portion of the Loans as provided in this Section 3.2; provided, however, that (i) each LIBOR Loan shall be in a principal amount of not less than One Million Dollars ($1,000,000) (and, if greater than One Million Dollars ($1,000,000), in integral multiples of One Hundred Thousand Dollars ($100,000)), (ii) no more than five (5) LIBOR Periods may be in existence at any one time, and (iii) Borrower may not select a LIBOR Rate for a Loan if there exists a Default or Event of Default. Borrower shall select LIBOR Periods with respect to LIBOR Loans so that no LIBOR Period expires after the end of the Original Term, or if extended pursuant to Section 3.3, any Renewal Term. With respect to a LIBOR Loan, the Borrowing Notice shall be delivered to Agent not later than two (2) Business Days before the proposed borrowing date referenced therein. An outstanding Base Rate Loan may be converted to a LIBOR Loan at any time subject to the provisions of this Section 3.2. (b) Each LIBOR Loan shall bear interest from and including the first day of the LIBOR Period applicable thereto (but not including the last day of such LIBOR Period) at the interest rate determined as applicable to such LIBOR Loan, but interest on such LIBOR Loan shall be payable as provided in Section 3.6. If at the end of an LIBOR Period for an outstanding LIBOR Loan, Borrower has failed to deliver to Lender a new Borrowing Notice with respect to such LIBOR Loan or to pay such LIBOR Loan, then such LIBOR Loan shall be converted to a Base Rate Loan on and after the last day of such LIBOR Period and shall remain a Base Rate Loan until paid or until the effective date of a new Borrowing Notice with respect thereto. 39

(c) If a Lender determines that maintenance of any of its portion of LIBOR Loans would violate any applicable law, rule, regulation or directive, whether or not having the force of law, such Lender shall suspend the availability of its portion of LIBOR Loans (the "Affected Portion") and require the Affected Portion of any LIBOR Loans outstanding to be repaid; or if such Lender determines that (i) deposits of a type or maturity appropriate to match fund the Affected Portion of LIBOR Loans are not available, or (ii) the LIBOR Rate does not accurately reflect the cost of making the Affected Portion of a LIBOR Loan, then such Lender shall promptly provide notice to Borrower of its decision to suspend Borrower's ability to make the Affected Portion of LIBOR Loans and/or require Borrower to repay the Affected Portion of LIBOR Loans and shall suspend the availability of the Affected Portion of LIBOR Loans after the date of any such determination. (d) If any payment of a LIBOR Loan occurs on a date which is not the last day of the applicable LIBOR Period, whether because of acceleration, prepayment or otherwise, or a LIBOR Loan is not made on the date specified by Borrower because Borrower has not satisfied the conditions precedent to such LIBOR Loan contained in this Agreement or a Default or Event of Default has occurred and is continuing, Borrower will indemnify Lenders for any loss or cost incurred by it resulting therefrom, including without limitation any loss or cost in liquidating or employing deposits required to fund or maintain the LIBOR Loan. (e) Agent shall deliver a written statement as to the amount due, if any, under Sections 3.2(c) or (d). Such written statement shall set forth in reasonable detail the calculations upon which Agent determined such amount and shall be final, conclusive and binding on Borrower in the absence of manifest error. Determination of amounts payable under such Sections in connection with a LIBOR Loan shall be calculated as though the affected Lender funded its portion of LIBOR Loan through the purchase of a deposit of the type and maturity corresponding to the deposit used as a reference in determining the LIBOR Rate applicable to such Loan whether in fact that is the case or not. Unless otherwise provided herein, the amount specified in the written statement shall be payable on demand after receipt by Borrower of the written statement. (f) Borrower may prepay a LIBOR Loan only upon at least three (3) Business Days prior written notice to Agent (which notice shall be irrevocable). Borrower shall pay to Agent, upon request of Agent, such amount or amounts as shall be sufficient (in the reasonable opinion of Agent) to compensate Lenders for any loss, cost, or expense incurred as a result of: (i) any payment of a LIBOR Loan on a date other than the last day of the LIBOR Period for such LIBOR Loan; (ii) any failure by Borrower to borrow a LIBOR Loan on the date specified by Borrower's written notice; or (iii) any failure by Borrower to pay a LIBOR Loan on the date for payment specified in Borrower's written notice. Without limiting the foregoing, Borrower shall pay to Agent for the benefit of Lenders a "yield maintenance fee" in an amount computed as follows: the current rate for United States Treasury securities (bills on a discounted basis shall be converted to a bond equivalent) with a maturity date closest to the LIBOR Period chosen pursuant to 40

the LIBOR Loan as to which the prepayment is made, shall be subtracted from the LIBOR Rate in effect at the time of prepayment. If the result is zero or a negative number, there shall be no yield maintenance fee. If the result is a positive number, then the resulting percentage shall be multiplied by the amount of the principal balance being prepaid. The resulting amount shall be divided by 360 and multiplied by the number of days remaining in the LIBOR Period chosen pursuant to the LIBOR Loan as to which the prepayment is made. Said amount shall be reduced to present value calculated by using the above referenced United States Treasury securities rate and the number of days remaining in the term chosen pursuant to the LIBOR Loan as to which prepayment is made. The resulting amount shall be the yield maintenance fee due to Agent for the benefit of Lenders upon the prepayment of a LIBOR Loan. If by reason of an Event of Default, Agent or the Majority Lenders elect to declare the Obligations to be immediately due and payable, then any yield maintenance fee with respect to a LIBOR Loan shall become due and payable in the same manner as though the Borrower had exercised such right of prepayment. Section 3.3 Term of Agreement. Subject to the terms hereof and to Lenders' right to cease making Loans to Borrower at any time upon or after the occurrence of an Event of Default, this Agreement shall be in effect for (a) a period of three (3) years from the date hereof, through and including February ___, 2005 (the "Term"). Upon written request by Borrower, Lenders may, in their sole and absolute discretion, renew this Agreement for any number of successive one year periods thereafter (each such successive one year period, a "Renewal Term"), but Lenders shall have no obligation to do so. Notwithstanding anything contained herein to the contrary, Lenders may terminate this Agreement without notice upon or after the occurrence of an Event of Default. Section 3.4 Early Termination by Borrower. Borrower may terminate the Revolving Credit Commitment hereunder at any time during the term of this Agreement by repaying all outstanding Loans and the interest thereon, plus a premium as follows: (i) if such prepayment occurs on or before the first anniversary of the Closing Date, a premium of 2% of the then existing Revolving Credit Commitment; (ii) if such prepayment occurs after the first anniversary of the Closing Date and on or before the second anniversary of the Closing Date a premium of 1.5% of the then existing Revolving Credit Commitment; and (iii) if such prepayment occurs after the second anniversary of the Closing Date and on or before the third anniversary of the Closing Date a premium of .5% of the then existing Revolving Credit Commitment. Section 3.5 Effect of Termination. All of the Obligations shall be forthwith due and payable upon any termination of this Agreement in accordance with Section 3.4. Except as otherwise expressly provided for in this Agreement or the other Loan Documents, no termination or cancellation (regardless of cause or procedure) of this Agreement or any of the other Loan Documents shall in any way affect or impair the rights, powers or privileges of Lenders or the obligations, duties or liabilities of Borrower or Lenders in any way relating to (a) any transaction or event occurring prior to such termination or cancellation or (b) any of the undertakings, agreements, covenants, warranties or representations of Borrower contained in this Agreement or any of the other Loan Documents. All such undertakings, agreements, covenants, warranties and representations of Borrower shall survive such termination or cancellation and Agent shall retain 41

its Liens in the Collateral and all of its rights and remedies under this Agreement and the other Loan Documents notwithstanding such termination or cancellation until all of the Obligations known existing, threatened or claimed which can be given a monetary value have been paid in full, in immediately available funds. Section 3.6 Payments. Principal and interest on the Loans shall be payable as follows: (a) principal payable on account of Loans shall be payable by Borrower to Lenders immediately upon the earliest of (i) the receipt by Agent, a Lender or Borrower of any proceeds of any of the Collateral, to the extent of said proceeds, (ii) the occurrence of an Event of Default in consequence of which Agent elects to accelerate the maturity and payment of such Loans, or (iii) termination of this Agreement. (b) interest accrued on the Loans shall be due on the earliest of (i) the first day of each month (for the immediately preceding month), computed through the last calendar day of the preceding month, (ii) the occurrence of an Event of Default in consequence of which Agent elects to accelerate the maturity and payment of the Obligations, or (iii) termination of this Agreement. (c) reasonable and itemized costs, fees and expenses payable pursuant to this Agreement shall be promptly payable by Borrower to Agent or to any other Person designated by Agent in writing. (d) the balance of the Obligations requiring the payment of money, if any, shall be payable by Borrower to Agent as and when provided in this Agreement, the Other Agreements or the Security Documents, or, if not otherwise provided, then on demand. Borrower hereby irrevocably authorizes Agent, in Agent's good faith discretion, to advance to Borrower and to charge to the Loan Account as a Revolving Loan, sums sufficient to pay all amounts due and payable under Sections 3.6(b), (c) and (d) above whether or not any such advance would cause the outstanding Revolving Loans to exceed the Borrowing Base. Section 3.7 Application of Payments and Collections. (a) Except as otherwise provided in this Section 3.7, Borrower irrevocably waives the right to direct the application of any and all payments and collections at any time or times hereafter received by Agent or Lenders from or on behalf of Borrower, and Borrower does hereby irrevocably agree that Agent shall have the continuing exclusive right to apply and reapply any and all such payments and collections received at any time or times hereafter by Agent or its agent against the Obligations, in such manner as Agent may deem advisable, notwithstanding any entry by Agent upon any of its books and records. If as the result of collections of Accounts as authorized by Section 5.2 a credit balance exists in the Loan Account with respect to the Revolving Credit Commitment, such credit balance shall not accrue interest in favor of Borrower, but shall be returned to Borrower within one (1) Business Day for so long as no Default or Event of Default exists. 42

Agent may offset any credit balance against the Obligations upon or after the occurrence of an Event of Default. Payments and collections received by Agent from the Dominion Account or otherwise in Houston, Texas (a) before 2:00 p.m. Central Standard Time on a Business Day shall be deemed received on such Business Day, and (b) after 2:00 p.m. Central Standard Time on a Business Day shall be deemed received on the next succeeding Business Day, in each case for purposes of determining the amount of Revolving Loans available for borrowing hereunder and for purposes of computing interest on the Loans (subject in each case to final payment of all items and collections received in form other than immediately available funds). For so long as no Event of Default has occurred, all payments and collections deposited into the Dominion Account shall be transferred to a bank account specified by Borrower, and upon the occurrence of an Event of Default, Agent may, in its sole discretion, direct all such payments and collections to be transferred to a bank account specified by Agent. (a) All monies to be applied to the Obligations, other than as expressly provided for elsewhere in this Agreement, whether such monies represent voluntary payments by the Borrower or are received pursuant to demand for payment or realized from any disposition of Collateral, shall be allocated among the Agent and such of the Lenders and other holders of the Obligations as are entitled thereto (and, with respect to monies allocated to the Lenders, on a ratable basis unless otherwise provided in this Section 3.7): (i) to pay principal and accrued interest on any Overadvance; (ii) second, to the Agent to pay the amount of expenses that have not been reimbursed to the Agent by the Borrower or the Lenders, together with interest accrued thereon; (iii) third, to the Agent to pay any indemnified amount that has not been paid to the Agent by the Borrower or the Lenders, together with interest accrued thereon; (iv) fourth, to the Agent to pay any fees due and payable to the Agent under this Agreement; (v) fifth, to the Lenders for any indemnified amount that they have paid to the Agent and for any expenses that they have reimbursed to the Agent; (vi) sixth, to the Lenders to pay any fees due and payable to the Lenders under this Agreement; (vii) seventh, in payment of the unpaid principal and accrued interest in respect of the Loans and (viii) eighth, any other Obligations then outstanding and held by any Lender to be shared among the Lenders on a ratable basis, or on such other basis as may be agreed upon in writing by all of the Lenders (which agreement or agreements may be entered into without notice to or the consent or approval of the Borrower). The allocations set forth in this Section 3.7 are solely to determine the rights and priorities of the Agent and the Lenders as among themselves and may be changed by the Agent and the Lenders without notice to or the consent or approval of the Borrower or any other Person. Section 3.8 Statements of Account. Agent will account to Borrower monthly with a statement of Loans, charges and payments made pursuant to this Agreement, and such account rendered by Agent, absent manifest error, shall be deemed final, binding and conclusive upon Borrower unless Agent is notified by Borrower in writing to the contrary within seventy-five (75) days after the date each account is mailed to Borrower. Such notice shall only be deemed an objection to those items specifically objected to therein. 43

Section 3.9 Increased Costs. If any law or any governmental or quasi-governmental rule, regulation, policy, guideline or directive (whether or not having the force of law) adopted after the date of this Agreement and having general applicability to all banks within the jurisdiction in which any Lender operates (excluding, for the avoidance of doubt, the effect of and phasing in of capital requirements or other regulations or guidelines passed prior to the date of this Agreement), or any interpretation or application thereof by any governmental authority charged with the interpretation or application thereof, or the compliance of any Lender therewith, shall: (a) (i) subject any Lender to any tax with respect to this Agreement (other than (A) any tax based on or measured by net income or otherwise in the nature of a net income tax, including, without limitation, any franchise tax or any similar tax based on capital, net worth or comparable basis for measurement and (B) any tax collected by a withholding on payments and which neither is computed by reference to the net income of the payee nor is in the nature of an advance collection of a tax based on or measured by the net income of the payee) or (ii) change the basis of taxation of payments to any Lender of principal, fees, interest or any other amount payable hereunder or under any Loan Documents (other than in respect of (A) any tax based on or measured by net income or otherwise in the nature of a net income tax, including, without limitation, any franchise tax or any similar tax based on capital, net worth or comparable basis for measurement and (B) any tax collected by a withholding on payments and which neither is computed by reference to the net income of the payee nor is in the nature of an advance collection of a tax based on or measured by the net income of the payee); (b) impose, modify or hold applicable any reserve (except any reserve taken into account in the determination of the applicable LIBOR Rate), special deposit, assessment or similar requirement against assets held by, or deposits in or for the account of, advances or loans by, or other credit extended by, any office of any Lender, including (without limitation) pursuant to Regulation D of the Board of Governors of the Federal Reserve System; or (c) impose on any Lender or the London interbank market any other condition with respect to any Loan Document; and the result of any of the foregoing is to increase the cost to any Lender of making, renewing or maintaining Loans hereunder by an amount that any Lender deems to be material or to reduce the amount of any payment (whether of principal, interest or otherwise) in respect of any of the Loans by an amount that any Lender deems to be material, then, in any such case, Borrower shall pay such Lender, upon demand and certification not later than sixty (60) days following its receipt of notice of the imposition of such increased costs, such additional amount as will compensate such Lender for such additional cost or such reduction, as the case may be, to the extent such Lender has not otherwise been compensated, with respect to a particular Loan, for such increased cost as a result of an increase in the Base Rate or the LIBOR Rate. An officer of such Lender shall determine the amount of such additional cost or reduced amount using reasonable averaging and attribution methods and shall certify the amount of such additional cost or reduced amount to Borrower, which certification shall include a written explanation of such 44

additional cost or reduction to Borrower and a statement that such costs affect other borrowers with similar LIBOR loans. Such certification shall be conclusive absent manifest error. If such Lender claims any additional cost or reduced amount pursuant to this Section 3.8, then such Lender shall use reasonable efforts (consistent with legal and regulatory restrictions) to designate a different lending office or to file any certificate or document reasonably requested by Borrower if the making of such designation or filing would avoid the need for, or reduce the amount of, any such additional cost or reduced amount and would not, in the sole discretion of such Lender, be otherwise disadvantageous to such Lender. Section 3.10 Basis for Determining Interest Rate Inadequate or Unfair. In the event that Agent shall have determined that: (a) reasonable means do not exist for ascertaining the LIBOR Rate for any LIBOR Period; or (b) Dollar deposits in the relevant amount and for the relevant maturity are not available in the London interbank market with respect to a proposed LIBOR Loan, or a proposed conversion of a Base Rate Loan into a LIBOR Loan; then Agent shall give Borrower prompt written, telephonic or electronic notice of the determination of such effect. If such notice is given, (i) any such requested LIBOR Loan shall be made as a Base Rate Loan, unless Borrower shall notify Agent no later than 10:00 A.M. (Dallas, Texas Time) two (2) Business Days prior to the date of such proposed borrowing that the request for such borrowing shall be canceled or made as an unaffected type of LIBOR Loan, and (ii) any Base Rate Loan which was to have been converted to an affected type of LIBOR Loan shall be continued as or converted into a Base Rate Loan, or, if Borrower shall notify Agent, no later than 10:00 A.M. (Dallas, Texas Time) two (2) Business Days prior to the proposed conversion, shall be maintained as an unaffected type of LIBOR Loan. ARTICLE 4. COLLATERAL: GENERAL TERMS Section 4.1 Security Interest in Collateral. To secure the prompt payment and performance to Lenders of the Obligations, Borrower hereby grants to Agent on behalf of the Lenders a continuing security interest in and Lien upon all the following Property and interests in Property of Borrower, whether now owned or existing or hereafter created, acquired or arising and wheresoever located: (a) Accounts; (b) Certificated Securities; (c) Chattel Paper (including Electronic Chattel Paper); (d) Computer Hardware and Software and all rights with respect thereto, including, any and all licenses, options, warranties, service contracts, program services, test rights, maintenance rights, support rights, improvement rights, renewal rights and indemnifications, and any substitutions, replacements, additions or model conversions of any of the foregoing; 45

therein, Agent will not enforce its security interest in Borrower's rights under such lease or license (other than in respect of the Proceeds thereof) for so long as such prohibition continues, it being understood that upon request of Agent, Borrower will in good faith use reasonable efforts to obtain consent for the creation of a security interest in favor of Agent (and to Agent's enforcement of such security interest) in such Agent's rights under such lease or license. Section 4.2 Other Collateral. (a) Commercial Tort Claims. Borrower shall promptly notify Agent in writing upon incurring or otherwise obtaining a Commercial Tort Claim after the Closing Date against any third party and, upon request of Agent, promptly enter into an amendment to this Agreement and do such other acts or things deemed appropriate by Agent to give Agent a security interest in any such Commercial Tort Claim. (b) Other Collateral. Borrower shall promptly notify Agent in writing upon acquiring or otherwise obtaining any Collateral after the date hereof consisting of Deposit Accounts, Investment Property, Letter-of-Credit Rights or Electronic Chattel Paper and, upon the request of Agent, promptly execute such other documents, and do such other acts or things deemed appropriate by Agent to deliver to Agent control with respect to such Collateral; promptly notify Agent in writing upon acquiring or otherwise obtaining any Collateral after the date hereof consisting of Documents or Instruments and, upon the request of Agent, will promptly execute such other documents, and do such other acts or things deemed appropriate by Agent to deliver to Agent possession of such Documents which are negotiable and Instruments, and, with respect to nonnegotiable Documents, to have such nonnegotiable Documents issued in the name of Agent; and with respect to Collateral in the possession of a third party, other than Certificated Securities and Goods covered by a Document and obtain an acknowledgement from the third party that it is holding the Collateral for the benefit of Agent. The security interests in the Collateral granted to Agent by Borrower are given in renewal, extension and modification of the security interests previously granted to Fleet by Cal Dive and ERT in the Amended Loan Documents; such prior security interests are not extinguished hereby; and the making, perfection and priority of such prior security interests shall continue in full force and effect. Section 4.3 Lien on Vessels. (a) The due and punctual payment and performance of the Obligations shall be secured by the Lien created by the Ship Mortgages upon the Vessels. Except as otherwise permitted herein, if Borrower shall acquire at any time or times hereafter any interest in other vessels, Borrower hereby agrees to promptly execute and deliver to Agent, as additional security and Collateral for the Obligations, Ship Mortgages or other collateral documents satisfactory in form and substance to Agent and its counsel (herein collectively referred to as "New Ship Mortgages") covering such new vessels. The Ship Mortgages and each New Ship Mortgage shall be duly recorded in each office where such recording is required to constitute a valid and perfected Lien on the vessels covered by such Mortgage. Borrower shall 47

deliver to Agent such other documents as Agent and its counsel may reasonably request relating to the Property subject to the Ship Mortgage and any New Ship Mortgages. (b) Upon demand by Agent, Borrower shall execute and deliver to Agent the Construction Contract Assignment and shall do all such other things deemed appropriate by Agent to perfect such assignment as a first preferred security interest on the collateral described in it. Section 4.4 Negative Pledge. Borrower agrees that for so long as any Obligations remain outstanding, it will not, without the prior written consent of Agent create or permit any Lien (other than Permitted Liens) or its interests in the Offshore Platforms and its other oil and gas Properties. Section 4.5 Representations, Warranties and Covenants. To induce Lenders to enter into this Agreement, Borrower represents, warrants, and covenants to Agent and Lender: (a) The Collateral is now and, so long as any of the Obligations are outstanding, will continue to be owned solely by Borrower, and no other Person has or will have any right, title, interest, claim, or Lien therein, thereon or thereto other than a Permitted Lien. (b) Except for Permitted Liens or as specifically consented to in writing by Agent the Liens granted to Agent shall be first and prior on the Collateral and as to the Accounts and proceeds, including insurance proceeds, resulting from the sale, disposition, or loss thereof. No further action need be taken to perfect the Liens granted to Lender, other than the filing of continuation statements under the Code or other applicable law, continued possession by Agent of that portion of the Collateral constituting instruments or documents, the recording of the Ship Mortgage and each New Ship Mortgage as required by applicable law. (c) All goods evidenced by the Collateral constituting chattel paper, documents or instruments, the possession of which has been given to Agent, are owned by Borrower and the same are free and clear of any prior Lien, except for Statutory Liens contested by Borrower as required by Section 8.2(h). Borrower further warrants and guarantees the value, quantities, adequate condition, grades and qualities of the goods and services described therein. Borrower shall pay and discharge when due all taxes, levies, and other charges upon said Collateral and upon the goods evidenced by any documents constituting Collateral, except and to the extent only that such taxes, levies and other charges are being actively contested in good faith and by appropriate lawful proceedings, and Borrower has established adequate reserves therefor, which are properly reflected on the Consolidated Financial Statements, and the nonpayment of such taxes, levies and charges does not result in a lien upon any Collateral other than a Permitted Lien. Borrower shall defend Agent against and save it harmless from all claims of any Person with respect to the Collateral. This indemnity shall include reasonable attorneys' fees and legal expenses. 48

Section 4.6 Lien Perfection. Borrower agrees to execute the UCC-1 financing statements provided for by the Code or otherwise together with any and all other instruments, assignments or documents and shall take such other action as may be required to perfect or to continue the perfection of Agent's security interest in the Collateral. Unless prohibited by applicable law, Borrower hereby authorizes Agent to execute and file any such financing statement on Borrower's behalf, including without limitation financing statements that indicate the Collateral (i) as all assets of Cal Dive, ERT, Aquatica or Canyon or words of similar effect, or (ii) as being equal or lesser in scope or with greater or lesser detail, than as set forth in Section 4.1 on Borrower's behalf. Borrower also hereby ratifies its authorization for the Agent to have filed in any jurisdiction any like financial statements or amendments thereto if filed prior to the date hereof. The parties agree that a carbon, photographic or other reproduction of this Agreement shall be sufficient as a financing statement and may be filed in any appropriate office in lieu thereof. Section 4.7 Location of Collateral. All Collateral, other than Inventory in transit, motor vehicles, Vessels and diving equipment, will at all times be kept by Borrower at one or more of the business locations set forth in Exhibit C attached hereto and shall not, without the prior written approval of Agent, be moved therefrom except, prior to an Event of Default, for (a) sales of Inventory and the providing of services in the ordinary course of business; (b) the storage of Inventory at locations within the continental United States other than those shown on Exhibit C attached hereto if (i) Borrower gives Agent written notice of the new storage location at least sixty (60) days prior to storing Inventory at such location, (ii) except for Statutory Liens contested by Borrower as required by Section 8.2(h), Agent's security interest in such Inventory is and continues to be a duly perfected, first priority Lien thereon, (iii) neither Borrower's nor Agent's right of entry upon the premises where such Inventory is stored, or its right to remove the Inventory therefrom, is in any way restricted, (iv) the owner of such premises agrees with Agent not to assert any landlord's, bailee's or other Lien in respect of the Inventory for unpaid rent or storage charges, and (v) all negotiable documents and receipts in respect of any Collateral maintained at such premises are promptly delivered to Agent; (c) temporary transfers (for period not to exceed three months in any event) of Equipment from a location set forth on Exhibit C attached hereto to another location if done for the limited purpose of repairing, refurbishing or overhauling such Equipment in the ordinary course of Borrower's business; and (d) removals in connection with dispositions of Equipment that are authorized by Section 6.4. Section 4.8 Insurance of Collateral. Borrower agrees to maintain and pay for insurance upon all Collateral (other than Offshore Platforms) wherever located, in storage or in transit, including goods evidenced by documents, covering casualty, hazard, public liability and such other risks and in such amounts and with insurance companies acceptable to Agent. Borrower shall deliver to Agent certificates regarding such insurance and the originals of such policies when available, with satisfactory endorsements naming Agent as loss payee or co-insured and as mortgagee pursuant to a standard mortgagee clause without liability for premiums, club calls or assessments. Each policy of insurance or endorsement shall contain a clause requiring the insurer to give not less than thirty (30) days prior written notice to Agent in the event of cancellation of the policy for any reason whatsoever and a clause that the interest of Agent shall not be impaired or invalidated by any act or neglect of Borrower or owner of the Property nor by the occupation of the premises for purposes more hazardous than are permitted by said policy. If Borrower fails to provide and pay for such insurance, Agent may, at 49

Borrower's expense, procure the same, but shall not be required to do so. Borrower agrees to deliver to Agent, promptly as rendered, true copies of all reports made in any reporting forms to insurance companies. Borrower will maintain, with financially sound and reputable insurers, insurance with respect to its Properties and business against such casualties and contingencies of such type (including public liability, product liability, larceny, embezzlement, or other criminal misappropriation insurance) and in such amounts as is customary in the business or as otherwise required by Agent. Section 4.9 Protection of Collateral. All insurance expenses and all expenses of protecting, storing, warehousing, insuring, handling, maintaining and shipping the Collateral, any and all excise, property, sales, and use taxes imposed by any state, federal, or local authority on any of the Collateral or in respect of the sale thereof shall be bome and paid by Borrower. If Borrower fails to promptly pay any portion thereof when due or is not actively contesting such taxes in good faith and by appropriate proceedings and has not established adequate reserves, which are properly reflected on the Consolidated Financial Statements, Agent may, at its option, but shall not be required to, pay the same and charge the Loan Account therefor. Borrower agrees to reimburse Agent promptly therefor with interest accruing thereon daily at the Applicable Annual Rate for Base Rate Loans. All sums so paid or incurred by Agent for any of the foregoing and all costs and expenses (including reasonable attorneys' fees, legal expenses, and court costs) which Agent may incur in enforcing or protecting its Lien on or rights and interest in the Collateral or any of its rights or remedies under any Loan Document or in respect of any of the transactions to be had hereunto, together with interest at the Default Rate applicable to Base Rate Loans, shall be considered Obligations hereunder secured by all Collateral. Agent shall not be liable or responsible in any way for the safekeeping of any of the Collateral or for any loss or damage thereto (except for reasonable care in the custody thereof while any Collateral is in Agent's actual possession) or for any diminution in the value thereof, or for any act or default of any warehouseman, carrier, forwarding agency, or other person whomsoever, but the same shall be at Borrower's sole risk. ARTICLE 5. PROVISIONS RELATING TO ACCOUNTS Section 5.1 Representations, Warranties and Covenants. With respect to all Accounts, Borrower represents and warrants to Agent and Lenders that Agent may rely, in determining which Accounts are Eligible Accounts, on all statements and representations made by Borrower with respect to any Account or Accounts, and, unless otherwise indicated in writing to Agent, that with respect to each Account: (a) it is genuine and in all respects what it purports to be, and it is not evidenced by a judgment; (b) it arises out of a completed, bona fide sale and delivery of goods or rendition of services by Borrower in the ordinary course of its business and in accordance with the terms and conditions of all purchase orders, contracts or other documents relating thereto and forming a part of the contract between Borrower and the Account Debtor; 50

(c) it has been generated in compliance with Borrower's normal credit policies as historically in effect (or as modified from time to time on prior written notice to Agent) or on such other reasonable terms disclosed in writing to Agent in advance of the creation of such Account, and such terms are expressly set forth on the face of the invoice covering such sale or rendition of services; (d) it is for a liquidated amount maturing as stated in the duplicate invoice covering such sale or rendition of services, a copy of which has been furnished or is available to Agent; (e) Borrower has made no agreement with any Account Debtor thereunder for any deduction therefrom, except discounts or allowances which are granted by Borrower in the ordinary course of its business and which are disclosed to Agent; (f) to the best of Borrower's knowledge, there are no facts, events or occurrences which have not been disclosed to Agent which in any way impair the validity or enforceability thereof or tend to reduce the amount payable thereunder from the face amount of the invoice and statements delivered to Agent with respect thereto; (g) to the best of Borrower's knowledge, the Account Debtor thereunder (i) is Solvent and (ii) had the capacity to contract at the time any contract or other document giving rise to the Account was executed; and (h) Borrower has no knowledge of any fact or circumstance which would impair the validity or collectability of the Account, and to the best of Borrower's knowledge there are no proceedings or actions which are threatened or pending against any Account Debtor thereunder which might result in any material adverse change in such Account Debtor's financial condition or the collectability of such Account. Section 5.2 Assignments, Records and Schedules of Accounts. If so requested by Agent, Borrower shall execute and deliver to Agent formal written assignments of all of its Accounts on a weekly or more frequent basis, which shall include all Accounts that have been created since the date of the last assignment, together with copies of invoices or invoice registers related thereto. Borrower shall keep accurate and complete records of its Accounts and all payments and collections thereon and shall submit to Agent on a weekly basis, unless requested on a more frequent basis by Agent, a sales and collections report for the preceding week, in form satisfactory to Agent. On or before the last day of each week from and after the date hereof, Borrower shall deliver to Agent, in form satisfactory to Agent, a detailed listing of all Unbilled Accounts existing as of the last day of the preceding week, a detailed aged trial balance of all Accounts existing as of the last day of the preceding week, specifying the names, face value, dates of invoices and due dates for each Account Debtor obligated on an Account so listed and a listing of all disputed amounts due and owing (a "Schedule of Accounts"), and upon Agent's request therefor, the reason for any disputed amounts, all claims related thereto and the amount in controversy, and addresses, copies of proof of delivery and the original copy of all documents, including, without limitation, repayment histories and present status reports relating to the Accounts so scheduled, and such other matters and information relating to the status of then existing Accounts as Agent shall reasonably request. 51

Section 5.3 Administration of Accounts. (a) Borrower shall report discounts, allowances or credits granted by Borrower that are not shown on the face of the invoice for the Account involved to Agent at the time of its submission to Agent of the next Schedule of Accounts as provided in Section 5.2 or more frequently upon the request of Agent. Upon and after the occurrence of an Event of Default, Agent shall have the right to settle or adjust all disputes and claims directly with the Account Debtor and to compromise the amount or extend the time for payment of the Accounts upon such terms and conditions as Agent may deem advisable, and to charge the deficiencies, costs and expenses thereof, including reasonable attorney's fees, to Borrower. (b) If an Account includes a charge for any tax payable to any governmental taxing authority, Agent is authorized, in its sole discretion, to pay the amount thereof to the proper taxing authority for the account of Borrower and to charge the Loan Account therefor. Borrower shall notify Agent if any Account includes any tax due to any govenunental taxing authority and, in the absence of such notice, Agent shall have the right to retain the full proceeds of the Account and shall not be liable for any taxes to any governmental taxing authority that may be due by Borrower by reason of the sale and delivery creating the Account. (c) Whether or not an Event of Default has occurred, any of Agent's officers, employees or agents shall have the right, at any time or times hereafter, in the name of Agent, any designee of Agent or Borrower, to verify the validity, amount or any other matter relating to any Accounts by mail, telephone, telegraph or otherwise. Borrower shall cooperate fully with Agent in an effort to facilitate and promptly conclude any such verification process. Section 5.4 Collection of Accounts. (a) To expedite collection, Borrower shall endeavor in the first instance to make collection of its Accounts for Agent. All remittances received by Borrower on account of Accounts shall be held as Agent's property by Borrower as trustee of an express trust for Agent's benefit and Borrower shall immediately deposit same in the Dominion Account. Agent shall have the right at any time after the occurrence of an Event of Default to notify Account Debtors that Accounts have been assigned to Agent and to collect Accounts directly in its own name and to charge the collection costs and expenses, including reasonable attorneys' fees, to Borrower. Agent has no duty to protect, insure, collect or realize upon the Accounts or preserve rights in them. (b) Borrower shall deposit all proceeds of the Collateral, other than receipts for the sale of Property held by third parties as reserves for like/kind exchanges, or cause the same to be deposited in kind in a Dominion Account pursuant to a lockbox arrangement with such banks as may be selected by Borrower and be acceptable to Agent. Borrower shall issue to any such bank, an irrevocable letter of instruction directing such banks to deposit all payments or other remittances 52

received in the lockbox to the Dominion Account for application on account of the Obligations. All funds deposited in the Dominion Account shall immediately become the property of Agent and Borrower shall obtain the agreement by such banks to waive any offset rights against the funds so deposited. Agent assumes no responsibility for such lockbox arrangement, including, without limitation, any claim of accord and satisfaction or release with respect to deposits accepted by any bank thereunder. ARTICLE 6. PROVISIONS RELATING TO EQUIPMENT, VESSELS AND OFFSHORE PLATFORMS Section 6.1 Representations, Warranties and Covenants. With respect to the Equipment, Vessels and the Offshore Platforms, Borrower represents, warrants and covenants to and with Agent that: (a) substantially all of the Equipment and the Vessels are in adequate operating condition and repair, and all necessary replacements of and repairs thereto shall be made so that the value and operating efficiency of the Equipment and the Vessels shall be maintained and preserved, reasonable wear and tear excepted; and (b) except for Equipment affixed to Offshore Platforms in the ordinary course of ERT's business, Borrower will not permit any of the Equipment to become affixed to any Real Property leased to Borrower so that an interest arises therein under the real estate laws of the applicable jurisdiction unless the landlord of such Real Property has executed a landlord waiver or leasehold mortgage in favor of Agent, and Borrower will not permit any of the Equipment to become an accession to any personal Property other than Equipment subject to first priority Liens in favor of Agent or subject to Permitted Liens. Section 6.2 Evidence of Ownership of Equipment and Vessels. Immediately on request therefor by Agent, Borrower shall deliver to Agent any and all evidence of ownership, if any, of any of the Equipment and the Vessels. Section 6.3 Records and Schedules of Equipment and the Vessels. Borrower shall maintain accurate records itemizing and describing the kind, type, quality, quantity, location and value of its Equipment and Vessels and all dispositions made in accordance with Section 6.4, and shall furnish Agent with a current schedule, in form and substance satisfactory to Agent, containing the foregoing information on at least an annual basis and more often if requested by Agent. Section 6.4 Dispositions. Borrower will not sell, lease or otherwise dispose of or transfer any of the Equipment, any Vessel, any Offshore Platform, or any oil or gas Properties, or any part thereof without the prior written consent of Agent; provided, however, that the foregoing restriction shall not apply to dispositions required by the United States government, or, for so long as no Event of Default exists, to the following: 53

(a) dispositions of Offshore Platforms and related Equipment and oil and gas Properties by ERT and vessels owned by Borrower and not mortgaged to Agent in the ordinary course of business; provided, that, all proceeds thereof, other than receipts for the sale of Property held by third parties as reserves for like/kind exchanges, are delivered to Agent for application to the Obligations in accordance with the terms of this Agreement; or (b) replacement of Equipment and Vessels that are substantially worn, damaged or obsolete with Equipment or Vessels of substantially like kind and function and with a value not less than the Equipment or Vessels being replaced; which replacement Equipment and Vessels shall be acceptable to Agent; provided, that, (i) the replacement Equipment or Vessels shall be acquired prior to concurrently with or within six (6) months of any disposition of the Equipment or Vessel that is to be replaced, (ii) the replacement Equipment or Vessels shall be free and clear of Liens other than Permitted Liens, (iii) Borrower shall give Agent at least five (5) days prior written notice of such disposition, and (iv) Borrower shall deliver to Agent all proceeds realized from any such disposition for application to the Obligations. (c) None of the provisos or other exceptions to the restriction against dispositions of Equipment, Vessels or Offshore Platforms set forth in this Section 6.4 shall be construed to allow any disposition, whether by Borrower of a Vessel on which Agent has been granted a Lien, without the prior written consent of Agent. ARTICLE 7. REPRESENTATIONS AND WARRANTIES Section 7.1 General Representations and Warranties.

(iv) In the event the Borrower obtains, gives or receives notice of any Release or threat of Release of a reportable quantity of any Hazardous Substances at the Real Property or on board the Vessels (any such event being hereinafter referred to as a "Hazardous Discharge") or receives any notice of violation, request for information or notification that it is potentially responsible for investigation or cleanup of environmental conditions, demand letter or complaint, order, citation, or other written notice alleging liability on the part of Borrower or any Subsidiary with regard to any Hazardous Discharge or violation of Environmental Laws (any of the foregoing is referred to herein as an "Environmental Complaint") from any Person or entity, including any state or local agency responsible in whole or in part for environmental matters in the state in which the Real Property is located , the United States Coast Guard, the United States Environmental Protection Agency or any similar agency of a foreign government where a Vessel is operating (any such person or entity hereinafter the "Authority"), then the Borrower shall, within ten (10) Business Days, give written notice of same to the Agent and furnish the Agent a copy of the Environmental Complaint.

The Borrower shall promptly forward to the Agent copies of all documents and reports concerning a Hazardous Discharge that the Borrower is required to file under any Environmental Laws.

(vi) Respond promptly to any Hazardous Discharge or Environmental Complaint and take all necessary action in order to safeguard the health of any Person and to avoid subjecting the Collateral or Real Property to any 67

If Borrower shall fail to so respond to any Hazardous Discharge or Environmental Complaint or Borrower shall fail to comply with any of the requirements of any Environmental Laws where the failure to do so would have a material adverse effect on its business, condition (financial or otherwise), operations, prospects or Properties, Agent may, but without the obligation to do so, for the sole purpose of protecting Agent's interest in Collateral after giving Borrower prior written notice: (a) give such notices or (b) enter onto the Real Property or Vessels (or authorize third parties to enter onto the Real Property or Vessels) and take such actions as Agent(or such third parties as directed by the Agent) deem reasonably necessary or advisable, to clean up, remove, or mitigate any such Hazardous Discharge or Environmental Complaint. All reasonable costs and expenses incurred by Agent (or such third parties) in the exercise of any such rights, including any sums paid in connection with any judicial or administrative investigation or proceedings, fines and penalties, together with interest thereon from the date expended at the Applicable Annual Rate for Base Rate Loans shall be paid upon demand by the Borrower, and until paid shall be added to and become a part of the Obligations secured by the Liens created by the terms of this Agreement or any other agreement between Agent or Lenders and Borrower. (vii) Promptly upon the written request of the Agent, in connection with any Hazardous Discharge or Environmental Complaint as described in clause (vi) immediately preceding, provide to Agent, at the Borrower's expense, with an environmental site assessment or environmental audit report prepared by an environmental engineering firm acceptable to Agent to assess with a reasonable degree of certainty the existence of a Hazardous Discharge and the potential costs in connection with abatement, cleanup and removal of any Hazardous Substances required as a result of the Hazardous Discharge or Environmental Complaint. Any investigation of or response to such Hazardous Discharge proposed and acceptable to an appropriate Authority that is charged to oversee the clean-up of such Hazardous Discharge shall be acceptable to the Agent. (viii) Defend and indemnify Agent and Lenders and hold Agent and Lenders, and their respective employees, agents, directors and officers harmless from and against all loss, liability, damage and expense, claims, costs, 68

fines and penalties, including attorney's fees, suffered or incurred by Agent or Lenders under or on account of any Environmental Laws, including, without limitation, the assertion of any Lien thereunder, with respect to any Hazardous Discharge, the presence of any Hazardous Substances affecting its business and operations, the Real Property or the Vessels, whether or not the same originates or emerges from the Real Property or any contiguous real estate or the Vessels, including any loss of value of the Real Property as a result of the foregoing. Borrower's obligations under this Section 8.1(u) shall arise upon the discovery of the presence of any Hazardous Substances at the Real Property or on board the Vessels that would have a material adverse effect on Borrower's business, condition (financial or otherwise), operations, prospects or Properties, or Borrower's use of Hazardous Substances in its business and operations in a manner that would have a material adverse effect on its business, condition (financial or otherwise), operations, prospects or Properties, whether or not any federal, state, or local environmental agency has taken or threatened any action in connection with the presence of any Hazardous Substances. Borrower's obligation and the indemnification hereunder shall survive the termination of this Agreement. (ix) For purposes of Section 7.1(aa), 8.1(u) and 8.2(aa), all references to "Real Property" shall be deemed to be all of Borrower's right, title and interest in and to all leased and owned premises, including, without limitation, the Offshore Platforms.

Upon and after the occurrence of an Event of Default, Agent shall have and may exercise from time to time the following rights and remedies: (a) All of the rights and remedies of a secured party under the Code, or under other applicable law, and all other legal and equitable rights to which Agent may be entitled, all of which rights and remedies shall be cumulative, and none of which shall be exclusive, and shall be in addition to any other rights or remedies contained in this Agreement or any of the other Loan Documents. (b) The right to take immediate possession of the Collateral, and (i) to require Borrower to assemble the Collateral, at Borrower's expense, and make it available to Agent at a place designated by Agent which is reasonably convenient to both parties, and (ii) to enter any of the premises of Borrower or wherever any of the Collateral shall be located, and to keep and store the same on said premises until sold (and if said premises be the Property of Borrower, Borrower agrees not to charge Agent for storage thereof). (c) The right to sell or otherwise dispose of all or any Inventory or Equipment in its then condition, or after any further manufacturing or processing thereof, at public or private sale or sales, with such notice as may be required by law, in lots or in bulk, for cash or on credit, all as Agent, in its discretion, may deem advisable. Borrower agrees that ten days written notice to Borrower of any public or private sale or other disposition of such Collateral shall be reasonable notice thereof, and such sale shall be at such locations as Agent may designate in said notice. Agent shall have the right to conduct such sales on Borrower's premises, without charge therefor, and such sales may be adjourned from time to time in accordance with applicable law. Agent shall have the right to sell, lease or otherwise dispose of such Collateral, or any part thereof, for cash, credit or any combination thereof, and Agent and Lenders may purchase all or any part of such Collateral at public or, if permitted by law, private sale and, in lieu of actual payment of such purchase price, may set off the amount of such price against the Obligations. 80

(d) Agent is hereby granted a license or other right to use, without charge, Borrower's labels, patents, copyrights, rights of use of any name, trade secrets, trade names, trademarks and advertising matter, or any Property of a similar nature, as it pertains to the Collateral, in advertising for sale and selling any Collateral and Borrower's rights under all licenses and all franchise agreements shall inure to Agent's benefit. (e) The proceeds realized from the sale of any Collateral may be applied, after allowing two Business Days for collection, first to the costs, expenses and reasonable attorneys' fees incurred by Agent in collecting the Obligations, in enforcing the rights of Agent and Lenders under the Loan Documents and in collecting, retaking, completing, protecting, removing, storing, advertising for sale, selling and delivery any of the Collateral; secondly, to interest due upon any of the Obligations; and thirdly, to the principal of the Obligations. (f) With respect to the face amount of all LC Guaranties and Letters of Credit issued by Agent may, at its option, require Borrower to deposit with Lender funds equal to such face amount, and if Borrower fails to promptly make such deposit, Lenders may advance such amount as a Revolving Loan (whether or not such advance would cause the outstanding balance of Revolving Loans to exceed the Borrowing Base). Any such deposit or advance shall be held by Agent as a reserve to fund future payments on such LC Guaranties and future drawings against such Letters of Credit. At such time as all LC Guaranties have been paid or terminated and all Letters of Credit issued by Issuing Bank have been drawn upon or expired, any amounts remaining in such reserve shall be applied against any outstanding Obligations, or to the extent all Obligations have been indefeasibly paid in full, returned to Borrower. Section 10.4 Remedies Cumulative: No Waiver. All covenants, conditions, provisions, warranties, guaranties, indemnities, and other undertakings of Borrower contained in this Agreement and the other Loan Documents, or in any document referred to herein or contained in any agreement supplementary hereto or in any schedule or contained in any other agreement between Agent or Lenders, or and Borrower, heretofore, concurrently, or hereafter entered into, shall be deemed cumulative to and not in derogation or substitution of any of the terms, covenants, conditions, or agreements of Borrower herein contained or of any of the other rights or remedies of Agent or Lenders as provided by any applicable law or in equity. The failure or delay of Agent or Lenders to exercise or enforce any rights, Liens, powers, or remedies hereunder or under any of the aforesaid agreements or other documents or security or Collateral or other rights or remedies shall not operate as a waiver of such Liens, rights, powers and remedies, but all such Liens, rights, powers, and remedies shall continue in full force and effect until all Loans and all other Obligations owing or to become owing from Borrower to Agent or Lenders shall have been fully satisfied, and all Liens, rights, powers, and remedies herein provided for are cumulative and none are exclusive. 81

ARTICLE 11. THE AGENT Section 11.1 Authorization and Action. Each Lender hereby appoints and authorizes Agent to take such action on its behalf and to exercise such powers under this Agreement, and the other Loan Documents as are delegated to Agent by the terms hereof and thereof, together with such powers as are reasonably incidental thereto. As to any matters not expressly provided for by this Agreement and the other Loan Documents (including, without limitations enforcement or collection of the Notes), Agent shall not be required to exercise any discretion or take any action, but shall be required to act or to refrain from acting (and shall be fully protected in so acting or refraining from acting) upon the instructions of the Majority Lenders, and such instructions shall be binding upon all Lenders; provided, however, that Agent shall not be required to take any action which exposes Agent to personal liability or which is contrary to this Agreement or the other Loan Documents or applicable law. To the extent the Lenders do not receive such materials directly from Borrower, Agent agrees to give each Lender promptly a copy of each notice, financial statement or report given to it by Borrower pursuant to the terms of this Agreement and the other Loan Documents. Section 11.2 Agent's Reliance, Etc. Neither Agent nor any of its directors, officers, agents or employees shall be liable for any action taken or omitted to be taken by it or them under or in connection with this Agreement or the other Loan Documents, except for its or their own gross negligence or willful misconduct. Without limitation of the generality of the foregoing, Agent: (a) may treat the payee of any Note as the holder thereof until Agent receives written notice of the assignment or transfer thereof signed by such payee and in form satisfactory to Agent; (b) may consult with legal counsel, independent public accountants and other experts selected by it and shall not be liable for any action taken or omitted to be taken in good faith by it in accordance with the advice of such counsel, accountants or experts; (c) makes no warranty or representations to any Lender and shall not be responsible to any Lender for any statements, warranties or representations made in or in connection with this Agreement or the other Loan Documents; (d) shall not have any duty beyond Agent's customary practices to ascertain or to inquire as to the performance or observance of any of the terms, covenants or conditions of this Agreement or the other Loan Documents on the part of any Loan Party or to inspect the property (including the books and records) of any Loan Party; (e) shall not be responsible to any Lender for the due execution, legality, validity, enforceability, genuineness, sufficiency or value of this Agreement or the other Loan Documents or any other instrument or document furnished pursuant hereto or thereto; and (f) shall incur no liability under or in respect of this Agreement or the other Loan Documents by acting upon any notice, consent, certificate or other instrument or writing (which may be by telecopy, telegram, cable or telex) believed in good faith by it to be genuine and signed or sent by the proper party or parties. Section 11.3 Fleet and Affiliates. With respect to its commitment hereunder to make Revolving Credit Loans, Fleet shall have the same rights and powers under this Agreement and the other Loan Documents as any other Lender and may exercise the same as though it were not Agent; and the term "Lender" or "Lenders" shall, unless otherwise expressly indicated, include Fleet in its individual capacity. Fleet and its Affiliates may lend money to, and generally engage in any kind of business with, Borrower or any of its Subsidiaries and any Person who may do business with or own Securities of Borrower or any such Subsidiary, all as if Fleet were not Agent and without any duty to account therefor to Lenders. 82

Section 11.4 Lender Credit Decision. Each Lender acknowledges that it has, independently and without reliance upon Agent or any other Lender and based on the financial statements referred to in Section 8.3 and such other documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement. Each Lender also acknowledges that it will, independently and without reliance upon Agent or any other Lender and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking action under this Agreement. Section 11.5 Indemnification. Lenders agree to indemnify Agent (to the extent not reimbursed by Borrower), ratably according to the respective principal amounts of the Notes then held by each of them, from and against any and all liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind or nature whatsoever which may be imposed on, incurred by, or asserted against Agent in any way relating to or arising out of this Agreement or any other Loan Document or any action taken or omitted by Agent under this Agreement, provided that no Lender shall be liable for any portion of such liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements resulting from Agent's gross negligence or willful misconduct. Without limitation of the foregoing, each Lender agrees to reimburse Agent promptly upon demand for its ratable shares of any out-of-pocket expenses (including counsel fees) incurred by Agent in connection with the preparation, execution, delivery, administration, modification, amendment or enforcement (whether through negotiations, legal proceedings or otherwise) of, or legal advice in respect of rights or responsibilities under, this Agreement and each other Loan Document, to the extent that Agent is not reimbursed for such expenses by Borrower. Section 11.6 Successor Agent. Agent may resign at any time by giving written notice thereof to Lenders and Borrower. Upon any such resignation, the Required Lenders shall have the right to appoint a successor Agent which shall be reasonably acceptable to Borrower. If no successor Agent shall have been so appointed by the Majority Lenders, and shall have accepted such appointment, within 30 days after the retiring Agent's giving notice of resignation, then the retiring Agent may, on behalf of the Lenders, appoint a successor Agent, which shall be a commercial bank or financial institution organized under the laws of the United States of America or of any State thereof and having a combined capital and surplus of at least Five Hundred Million Dollars ($500,000,000). Upon the acceptance of any appointment as Agent hereunder by a successor Agent, such successor Agent shall thereupon succeed to and become vested with all the rights, powers, privileges and duties of the retiring Agent, and the retiring Agent shall be discharged from its duties and obligations under this Agreement and the other Loan Documents. After any retiring Agent's resignation hereunder as Agent, the provisions of this Section 11 shall inure to its benefit as to any actions taken or omitted to be taken by it while it was Agent under this Agreement and the other Loan Documents. Section 11.7 Communications to and from Agent. When any notice, approval, consent, waiver or other communication or action is required or may be delivered by the Lenders hereunder or the other Loan Documents, action by the Agent shall be effective for all purposes hereunder; provided, that upon any occasion requiring or permitting an approval, consent, waiver, election or other action on the part of the Lenders, unless action by the Agent alone, or only upon instruction of all of the Lenders, is expressly 83

permitted or required hereunder, action shall be taken by the Agent for and on behalf of or for the benefit of all the Lenders as provided in Section 11.1above. The Borrowers may rely on any communication from the Agent hereunder or the other Loan Documents, and need not inquire into the propriety of or authorization for such communication. Upon receipt by the Agent from the Borrower or any Lender of any communication it will, in turn, promptly forward such communication to the Lenders; provided, however, that the Agent shall not be liable for any costs, expenses or losses arising from any failure to so forward any such communication. Section 11.8 Limitations of Agency. Notwithstanding anything in the Loan Documents, expressed or implied, it is agreed by the parties hereto, that the Agent will act under the Loan Documents as Agent solely for the Lenders and only to the extent specifically set forth herein, and will, under no circumstances, be considered to be an agent or fiduciary of any nature whatsoever in respect to any other person. Section 11.9 No Representations or Warranty. (a) No Lender (including the Agent) makes to any other Lender any representation or any warranty, expressed or implied, or assumes any responsibility with respect to the Loan or the execution, construction or enforceability of the Loan Documents or any instrument or agreement executed by the Borrower or any other Person in connection therewith. (b) The Agent takes no responsibility for the accuracy or completeness of any information concerning the Borrower distributed by the Agent in connection with the Loan nor for the truth of any representation or warranty given or made herein, nor for the validity, effectiveness, adequacy or enforceability of this Agreement or any of the other Loan Documents. Section 11.10 Distribution. The Agent shall be responsible for promptly distributing each Lender's share of all net amounts received by the Agent under any of the Loan Documents pursuant to the terms of the Loan Documents. Each Lender shall be responsible for designating by written notice to the Agent the account to which such distribution shall be deposited. Section 11.11 Limitation of Suits. All rights of action and claims under this Agreement and the other Loan Documents of the Lenders shall be prosecuted and enforced only by the Agent. The Lenders agree that they shall not independently institute any proceedings, judicial or otherwise, to enforce their rights against the Borrowers under this Agreement and the other Loan Documents. However, notwithstanding anything contained in this Section 11.11, the Lenders shall always retain their ability to retain independent counsel and to protect their rights under this Agreement and the other Loan Documents. Section 11.12 Right of Setoff. 84

Upon the occurrence and during the continuation of any Event of Default, the Lenders each are hereby authorized at any time and from time to time, without notice to the Borrower (any such notice being expressly waived by the Borrower), to setoff and apply any and all deposits (general or special, time or demand, provisional or final, whether or not such setoff results in any loss of interest or other penalty, and including without limitation all certificates of deposit) at any time held by the Lenders and all of the indebtedness arising in connection with this Agreement irrespective of whether or not such Lender will have made any demand under this Agreement, the Note or any other Loan Document. The Borrower also hereby grants to each of the Lenders a security interest in and hereby transfers, assigns, sets over and conveys to each of the Lenders, as security for payment of the Loan, all such deposits, funds or property of the Borrower or indebtedness of any Lender to the Borrower. Should the right of any Lender to realize funds in any manner set forth hereinabove be challenged and any application of such funds be reversed, whether by court order or otherwise, the Lenders shall make restitution or refund to the Borrower pro rata in accordance with their respective portions of the Loan. Each Lender agrees to promptly notify the Borrower and the Agent after any such setoff and application, provided that the failure to give such notice will not affect the validity of such setoff and application. The rights of the Agent and the Lenders under this Section 11.12 are in addition to other rights and remedies (including without limitation other rights of setoff) which the Agent or the Lenders may have. Nothing contained herein shall affect the right of any Lender to exercise, and retain the benefits of exercising, any such right with respect to any other indebtedness or obligation of the Borrower to such Lender. ARTICLE 12. MISCELLANEOUS Section 12.1 Power of Attorney. Borrower hereby irrevocably designates, makes, constitutes and appoints Agent (and all Persons designated by Agent) as Borrower's true and lawful attorney (and agent-in-fact) and Agent, or Agent's agent, may, in either Borrower's or Agent's name, but at the cost and expense of Borrower: (a) At such time or times hereafter as Agent or said agent may determine and after notice to Borrower, endorse Borrower's name on any checks, notes, acceptances, drafts, money orders or any other evidence of payment or proceeds of the Collateral which come into the possession of Agent or under Agent's control; and (b) At such time or times upon or after the occurrence of an Event of Default as Agent or its agent may determine: (i) demand payment of the Accounts from the Account Debtors, enforce payment of the Accounts by legal proceedings or otherwise, and generally exercise all of Borrower's rights and remedies with respect to the collection of the Accounts; (ii) settle, adjust, compromise, discharge or release any of the Accounts or other Collateral or any legal proceedings brought to collect any of the Accounts or other Collateral; (iii) sell or assign any of the Accounts and other Collateral upon such terms, for such amounts and at such time or times as Agent deems advisable; (iv) take control, in any manner, of any item of payment or proceeds relating to any Collateral; (v) prepare, file and sign Borrower's name to a proof of claim in bankruptcy or similar document against any Account Debtor or to any notice of lien, assignment or satisfaction of lien or similar document in connection with any of the Collateral; (vi) receive, 85

open and dispose of all mail addressed to Borrower and to notify postal authorities to change the address for delivery thereof to such address as Agent may designate; (vii) endorse the name of Borrower upon any of the items of payment or proceeds relating to any Collateral and deposit the same to the account of Agent on account of the Obligations; (viii) endorse the name of Borrower upon any chattel paper, document, instrument, invoice, freight bill, bill of lading or similar document or agreement relating to the Accounts, Inventory, and any other Collateral; (ix) use Borrower's stationery and sign the name of Borrower to verifications of the Accounts and notices thereof to Account Debtors; (x) use the information recorded on or contained in any data processing equipment and computer hardware and software relating to the Accounts, Inventory, Vessels, Equipment and any other Collateral and to which Borrower has access; (xi) make and adjust claims under policies of insurance; and (xii) do all other acts and things necessary, in Agent's determination, to fulfill Borrower's obligations under this Agreement. Section 12.2 Indemnity. Borrower hereby indemnifies, holds harmless, and shall defend Agent and Lenders and their directors, officers, agents, counsel and employees ("Indemnified Persons") from and against any and all losses, liabilities, damages, costs, expenses, suits, actions and proceedings ("Losses") ever suffered or incurred by any Indemnified Person arising out of or relating to this Agreement or any other transaction contemplated hereby, including, without limitation, any Losses caused by the negligence of such Indemnified Person, but not including any Losses caused by the gross negligence or willful misconduct of such Indemnified Person, and Borrower shall reimburse Agent and Lenders and each other Indemnified Person for any expenses (including in connection with the investigation of, preparation for or defense of any actual or threatened claim, action or proceeding arising therefrom, including any such costs of responding to discovery requests or subpoenas, regardless of whether Agent and Lenders or such other Indemnified Person is a party thereto). Without limiting the generality of the foregoing, this indemnity shall extend to any claims asserted against Agent and Lenders or any other Indemnified Person by any Person under any Environmental Laws or similar laws by reason of Borrower's or any other Person's failure to comply with laws applicable to solid or hazardous waste materials or other toxic substances. Borrower may select counsel with respect to any Losses; provided, however, each Indemnified Person shall have the right to monitor the progress of any claims, suits and administrative proceedings defended by Borrower hereunder with counsel of such Indemnified Person's choice, or conduct its defense through counsel of such Indemnified Person's choice, in the event that (i) such Indemnified Person determines in good faith that the conduct of its defense by Borrower could be materially prejudicial to such Indemnified Person's interests or that other reasonable grounds exist which demonstrate a lack of effectiveness or high level of quality in the conduct of such defense by Borrower, and (ii) prior to retaining such counsel for such purpose, such Indemnified Person shall consult with Borrower and shall attempt in good faith to agree upon counsel to conduct the defense on behalf of Borrower and such Indemnified Person, and in each case the fees and disbursements of such counsel shall be paid by Borrower; provided, however, that if such mutual agreement is not reached within a reasonable time on selecting counsel, then such Indemnified Person may retain its own counsel at Borrower's expense. Notwithstanding any contrary provision of this Agreement, the obligation of Borrower under this Section 12.2 shall survive the payment in full of the Obligations and the termination of this Agreement. 86

Section 12.3 Reimbursement of Expenses. Without limiting Borrower's obligations for payment of expenses as provided elsewhere in this Agreement or in any other Loan Document, if, at any time or times prior or subsequent to the date hereof, regardless of whether or not an Event of Default then exists or any of the transactions contemplated hereunder are concluded, Agent or Lenders incur any out-of-pocket expenses (including, without limitation, the fees and expenses of Agent or Lenders' attorneys if Agent or Lenders retain legal counsel) in connection with: (a) the negotiation and preparation of the Loan Documents, any amendment or modification of any Loan Documents; or (b) the administration of the Loan Documents and the transactions contemplated thereby; (c) any litigation, contest, dispute, suit, proceeding or action (whether instituted by Agent, Lenders, Borrower or any other Person) in any way relating to the Collateral, any Loan Documents, Agent's, Lenders' and Borrower's relationship, or Borrower's affairs; (d) any attempt to enforce any rights of Agent or Lenders against Borrower or any other Person which may be obligated to Agent or Lenders by virtue of any Loan Documents, including, without limitation, the Account Debtors; (e) the exercise or enforcement of any rights, remedies or privileges of Lender under the Loan Documents or applicable law; (f) the analysis of information received in connection with any Loan Documents; (g) the audit or appraisal of any Collateral or Borrower's books and records; (h) the granting of any consents or waivers requested in connection with the Loan Documents; (i) the collection of any Obligations; or (j) any attempt to inspect, verify, protect, preserve, restore, collect, sell, liquidate or otherwise dispose of or realize upon the Collateral; then, in any such event, all expenses, costs, charges and other fees incurred by Agent, Lender or their attorneys or relating to any of the events or actions described in this Section 12.4 shall be payable, on demand, by Borrower to Agent, and shall be additional Obligations hereunder secured by the Collateral. Without limiting the generality of the foregoing, such expenses, costs, charges and fees may include: recording costs; appraisal costs; accountants' fees, costs and expenses; court costs and expenses; photocopying and duplicating expenses; court reporter fees, costs and expenses; attorney and paralegal fees, costs and expenses; long distance telephone charges; air express charges; telegram and facsimile charges; wire transfer fees; secretarial overtime charges; and expenses for travel, lodging and food. Additionally, if any taxes (excluding taxes imposed upon or measured by the net income of Agent or Lenders) shall be payable on account of the execution or delivery of any of the Loan Documents, or the creation of any of the Obligations hereunder, by reason of any existing or hereafter enacted federal or state statute, Borrower will pay all such taxes, including, but not limited to, any interest and penalties thereon, and will indemnify and hold Lender harmless from and against liability in connection therewith. Notwithstanding anything else contained in this Agreement, Borrower shall have no obligation to reimburse or indemnify any Lender for its costs, expenses or losses if they arise out of an action by Borrower to enforce such Lender's several obligations under this Agreement and Borrower is successful in such an action. Section 12.4 Indulgences Not Waivers. Agent's failure, at any time or times hereafter, to require strict performance by Borrower of any provision of this Agreement shall not waive, affect or diminish any right of Agent thereafter to demand strict compliance and performance therewith. Any suspension or waiver by Agent of an Event of Default by Borrower under this Agreement or any of the other Loan Documents shall not suspend, waive or affect any other Event of Default by Borrower under this Agreement or any of the other Loan Documents, whether the same is prior or subsequent thereto and whether of the same or of a different type. None of the undertakings, agreements, warranties, covenants and representations of Borrower contained in this Agreement or any of the other Loan Documents and no Event of Default by 87

Borrower under this Agreement or any of the other Loan Documents shall be deemed to have been suspended or waived by Agent, unless such suspension or waiver is by an instrument in writing specifying such suspension or waiver and is signed by a duly authorized representative of Agent and sent to Borrower. Section 12.5 Severability. Wherever possible, each provision of this Agreement shall be interpreted in such manner as to be effective and valid under applicable law, but if any provision of this Agreement shall be prohibited by or invalid under applicable law, such provision shall be ineffective only to the extent of such prohibition or invalidity, without invalidating the remainder of such provision or the remaining provisions of this Agreement. Section 12.6 Modification of Agreement; Sale of Interest. (a) The Loan Documents constitute the complete agreement between the parties with respect to the subject matter hereof and may not be modified, altered or amended except by an agreement in writing signed by Borrower, Majority Lenders and, if required by the terms hereof, Agent. No Borrower may sell, assign or transfer any of the Loan Documents, or any of the Obligations, or any portion thereof, including without limitation, any Borrower's rights, title, interests, remedies, powers and duties hereunder or thereunder. Each Borrower hereby consents to Agent's and any Lender's sale of participation, assignment, transfer or other disposition in accordance with the terms of this Section 12.6, at any time or times, of any of the Loan Documents or of any portion thereof or interest therein, including, without limitation, Agent's and any Lender's rights, title, interests, remedies, powers or duties thereunder, whether evidenced in writing or not; Each Borrower agrees that it will use its best efforts to assist and cooperate with Agent and any Lender in any manner reasonably requested by Agent or such Lender to effect the sale of participation in or assignment of any of the Loan Documents or of any portion thereof or interest therein, including, without limitation, assistance in the preparation of appropriate disclosure documents or placement memoranda and executing appropriate amendments to the signature pages hereto to reflect the addition of any Lenders and such Lender's respective commitments. The foregoing notwithstanding, except with respect to sales, assignments or transfers to Affiliates under common control pursuant to which the selling, assigning or transferring Lender retains its voting rights, no Lender shall sell participate or assign, transfer or otherwise dispose of any of the Loan Documents or any portion thereof or interest therein, without the prior written consent of Agent, which shall not be unreasonably withheld. (b) In respect to any assignment by a Lender of its rights and obligations under this Agreement (including, without limitation, all or a portion of its Revolving Credit Commitments, the Revolving Loans owed to it and the Note held by it (i) each such assignment shall be of a uniform, and not a varying, percentage of all rights and obligations, (ii) except in the case of an assignment of all of a Lender's rights and obligations under this Agreement, (A) the aggregate amount of the Revolving Credit Commitments of the assigning Lender being assigned pursuant to each such assignment (determined as of the date of the Assignment and Acceptance 88

with respect to such assignment) shall in no event be less than $2,000,000, and in integral multiples of $1,000,000 thereafter, or such lesser amount as to which Borrower and the Agent may consent to and (B) after giving effect to each such assignment in the amount of the Revolving Credit Commitments of the Assigning Lender shall in no event be less than $2,000,000, (iii) the parties to each such assignment shall execute and deliver to the Agent, for its acceptance, an Assignment and Acceptance in the form of Exhibit Y hereto (an "Assignment and Acceptance"), together with any Note subject to such assignment and a processing and recordation fee of $3,500, and (iv) any Lender may without the consent of Borrower or the Agent, and without paying any fee, assign to any Affiliate of such Lender that is a bank or financial institution all of its rights and obligations under this Agreement. The foregoing notwithstanding, no Person may become a Lender or a Participating Lender hereunder, unless such Person is a financial institution having stockholders' equity (or the equivalent) of at least One Hundred Million Dollars ($100,000,000). Upon such execution, delivery, acceptance and recording, from and after the effective date specified in such Assignment and Acceptance (x) the assignee thereunder shall be a party hereto and, to the extent that rights and obligations hereunder have been assigned to it pursuant to such Assignment and Acceptance, have the rights and obligations of a Lender hereunder and (y) the Lender assignor thereunder shall, to the extent that rights and obligations hereunder have been assigned by it pursuant to such Assignment and Acceptance, relinquish its rights and be released from its obligations under this Agreement (and, in the case of an Assignment and Acceptance covering all of the remaining portion of an assigning Lender's rights and obligations under this Agreement, such Lender shall cease to be a party hereto). If, pursuant to this Section 12.6, any interest in this Agreement or any Revolving Credit Loan or any Note is transferred to any transferee which is organized under the laws of any jurisdiction other than the United States or any state thereof, the transferor Lender shall cause such transferee (other than any Participating Lender), and may cause any Participating Lender concurrently with the effectiveness of such transfer, (a) to represent to the transferor Lender (for the benefit of the transferor Lender, Agent and Borrower) that under applicable law and treaties no Taxes will be required to be withheld by Agent, Borrower or the transferor Lender with respect to any payments to be made to such transferee in respect of the Revolving Credit Loans, or the Notes, (b) to furnish to the transferor Lender, Agent or Borrower either U.S. Internal Revenue Service Form 4224 or U.S. Internal Revenue Service Form 1001 (wherein such transfer claims entitlement to complete exemption form U.S. federal withholding tax on all interest payments hereunder), and (c) to agree (for the benefit of the transferor Lender, Agent and Borrower) to provide the transferor Lender, Agent and Borrower a new Form 4224 or Form 1001 upon the obsolescence of any previously delivered form and comparable statements in accordance with applicable U.S. laws and regulations and amendments duly executed and completed by such transferee, and to comply from time to time with all applicable U.S. laws and regulations with regard to such withholding tax exemption. 89

(c) In addition to, and not in limitation of the foregoing, Borrower acknowledges that if Fleet intends to sell, assign or participate any of its Revolving Credit Commitments, Borrower agrees to use its best efforts to assist Fleet in any respect to any such sale, assignment or participation. (i) In the event any Lender assigns or otherwise transfers all or any part of its Note any such Lender shall so notify Borrower and Borrower shall, upon the request of such Lender, issue new Notes in exchange for the old Notes. (ii) Any Lender may at any time sell to one or more commercial banks, financial institutions, or other Persons not Affiliates of Borrower (a "Participating Lender") participating interests in any Loans, the Revolving Credit Commitments of that Lender and the other interests of that Lender (the "Originating Lender") hereunder and under the other Loan Documents; provided, however, that (i) the Originating Lender's obligations under this Agreement shall remain unchanged, (ii) the Originating Lender shall remain solely responsible for the performance of such obligations, (iii) Borrower and the Agent shall continue to deal solely and directly with the Originating Lender in connection with the Originating Lender's rights and obligations under this Agreement and the other Loan Documents, and (iv) no Lender shall grant any participation under which the Participating Lender shall have rights to approve any amendment to or waiver of this Agreement or the Loan Documents, except to the extent such amendment or waiver would: (A) extend the final maturity date for payment of the Loans in which such Participating Lender is participating; (B) reduce the interest rate or the amount of principal or fees applicable to the Loans in which such Participating Lender is participating; or (C) release all or substantially all of the Collateral, except as expressly provided herein. In those cases in which an Originating Lender grants rights to a Participating Lender to approve any amendment to or waiver of this Agreement or the other Loan Documents respecting the matters described in clauses (A) through (C) of the preceding sentence, the relevant participation agreements shall provide for a voting mechanism whereby a majority of the amount of such Lender's portion of the Loans (irrespective of whether held by such Lender or participated) shall control the vote for all of such Lender's portion of the Loans. In the case of any participation, the Participating Lender shall not have any rights under this Agreement or any of the other Loan Documents entered into in connection herewith (the Participating Lender's right against such Lender in respect of such participation to be those set forth in the participation or other agreement executed by such Lender and the Participating Lender relating thereto). In no event shall any Participating Lender grant a participation in its participation interest in the Loans without the prior written consent of Agent, which approval shall not be unreasonably withheld. All amounts payable by Borrower hereunder shall be determined as if the Originating Lender had not sold any such participation, except that, if amounts outstanding under this Agreement are due and unpaid, or shall have been 90

declared or shall have become due and payable upon the occurrence of an Event of Default, each Participating Lender shall be deemed to have the right of set-off in respect of its participating interest in amounts owing under this Agreement to the same extent as if the amount of its participating interest were owing directly to it as a Lender under this Agreement.

Notwithstanding any other provision hereof, the Lessor shall not be obligated to make any Advance with respect to the Platform if, after giving effect thereto, (i) the aggregate outstanding amounts of the Tranche A Loans, Tranche B Loans and the Equity Amounts would exceed the aggregate Commitments of the Tranche A Lenders, the Tranche B Lenders and the Certificate Holders, or (ii) the remaining Allocated Estimated Construction Costs at such time exceed the remaining aggregate amount of undisbursed Commitments. (ii) Subject to the conditions and terms hereof, each Certificate Holder severally agrees that it shall personally make available at the request of the Lessee from time to time during the Commitment Period, on each Funding Date an amount (each an "EQUITY AMOUNT") in immediately available funds equal to such Certificate Holder's applicable Commitment Percentage of the amount of the Advance being funded on such Funding Date. Notwithstanding any other provision hereof, no Certificate Holder shall be obligated to make available any Equity Amount if, after giving effect to the proposed Equity Amount, the outstanding aggregate amount of such Certificate Holder's Equity Amounts would exceed such Certificate Holder's Commitment. (b) LENDERS' COMMITMENT.

Notwithstanding any other provision hereof, no Lender shall be obligated to make any Loan if, after giving effect to the proposed Loan, the outstanding aggregate amount of such Lender's Loans would exceed such Lender's Commitment. (c) PROCEDURES FOR ADVANCES. (i) With respect to each funding of an Advance, the Lessee shall give the Lessor and the Agent prior written notice not later than 10:00 a.m., Chicago time, three (3) Business Days (unless waived) prior to the proposed Funding Date and, in the case of the first Funding Date two (2) Business Days prior to such Funding Date pursuant to an irrevocable Funding Request substantially in the form of Exhibit I (a "FUNDING REQUEST"), specifying the proposed Funding Date, the amount of Advance requested and such other information and documents as required pursuant to the terms of this Agreement. Except for the final Funding Request, each Funding Request shall be in an amount at least equal to $1,000,000 and in multiples of $100,000 if in excess of such amount. Lessee shall request one (1) Funding Participation Agreement 4

Date per month and be allowed a maximum of 2 separate LIBOR tranches at any one time. The proceeds of each funding will be used to pay the Construction Agent for accrued but unpaid Allocated Construction Costs (including, without limitation, Construction Period Interest, Construction Period Yield, Construction Period Fees, Construction Period Indemnity Amounts and Transaction Expenses); and the Funding Date therefor shall be a date on or before the applicable Scheduled Payment Date; provided, however, that if the Lessee fails to duly and timely submit a Funding Request which provides for the payment of Construction Period Interest, Construction Period Yield, Construction Period Fees, Construction Period Indemnity Amounts or Transaction Expenses on the applicable Scheduled Payment Date, the Lessee hereby irrevocably authorizes and directs the Agent (at its option) to cause the Participants to fund to the Participants such amounts as may be necessary to pay in full all such amounts. (i) Upon satisfaction or waiver of the conditions precedent to such Advance set forth in Section 9(c), the Lessee, as Construction Agent, shall pay (or cause the Operator to pay) Allocated Construction Costs with the funds provided by the Certificate Holders and the Lenders for such Advance. The transfer by any Participant of its portion of an Advance shall evidence such Participant's satisfaction that the conditions precedent to such Advance have been met or waived. Except as set forth above and as the parties may otherwise agree in writing, Advances shall be made solely to provide the Lessee or the Construction Agent with funds with which to pay Allocated Construction Costs. (ii) All remittances made by the Participants for the funding of any Advance shall be made on the applicable Funding Date in immediately available Federal funds by wire transfer to the accounts specified in the applicable Funding Request. Subject to the prior satisfaction of all of the applicable conditions set forth in Section 9, the Participants will use reasonable efforts to fund the applicable Advance prior to 2:00 p.m., Chicago time, on such Funding Date. (iii) In no event will the total Property Balance at any time exceed (i) the Construction Cost as set forth in the Approved Budget, in the aggregate whether under construction or completed and still subject to the Lease, or (ii) the Fair Market Sales Value of the Platform expected upon Completion, as set forth in the Appraisal. (iv) In no event shall the Lenders or Certificate Holders be required to make, and the Lenders and the Certificate Holders shall have no obligation to, fund any Advance or portion thereof which is to be allocated to Cost Overruns. (d) CAPITALIZATION OF CERTAIN AMOUNTS DURING CONSTRUCTION PERIOD. During the Construction Period, on each date which is three (3) Business Days prior to any Payment Date, Lessee shall be deemed to have requested in Advance in an amount equal to the applicable Construction Period Interest, Construction Period Yield, Construction Period Fees and Construction Period Indemnity and Supplemental Rent Amounts which have accrued or are due, as the case may be. The Funding Date with respect to each such Advance for such Construction Period Interest, Construction Period Yield, Construction Period Fees and Construction Period Indemnity and Supplemental Rent Amounts shall be the relevant Payment Date (subject to the terms and conditions for an Advance set forth in this Participation Agreement) and the proceeds of such Advance shall be applied to pay such amounts (and will be deemed to satisfy any Participation Agreement 5

corresponding Rent payment obligation). On each such Funding Date as to which such an Advance is being made, the Construction Costs shall be increased by an amount equal to the Construction Period Interest, the Construction Period Yield, the Construction Period Fees and Construction Period Indemnity and Supplemental Rent Amounts so funded; provided, however, that if any such Advance hereunder would exceed the Available Commitment of a Participant, such Participant shall not have any obligation to make any such Advance. (e) NON-FUNDING LENDER. In the event that any Lender (a "DEFAULTING LENDER") fails to make available on a Funding Date an amount equal to such Lender's applicable Commitment Percentage of the amount of the Advance required by the terms hereof to be funded on such Funding Date (a "DEFAULTED AMOUNT"), or Agent determines that a Lender will become a Defaulting Lender on the applicable Funding Date, Agent shall promptly notify Lessee thereof and Lessee shall have the option, except in respect of any Advance pursuant to the preceding paragraph (d) and without in any way waiving the occurrence of any Default, to postpone the funding of the entire Advance or the portion thereof representing the Defaulted Amount (provided, however, that such postponement shall in no event relieve Lessee of its obligation to pay as Rent any Break Costs suffered or incurred by any Participant, but Lessee may offset any such costs against amounts otherwise payable by it, under the Operative Documents or otherwise, to the Defaulting Lender). Whether or not such option is exercised, the Agent may elect to have the Defaulting Lender replaced with a new Lender reasonably acceptable to Lessee, and Agent and the Defaulting Lender shall cooperate (at the cost of the Defaulting Lender) in replacing such Defaulting Lender. Notwithstanding the existence of any Defaulting Lender, each other Lender (each, a "NON-DEFAULTING LENDER") shall timely fund its respective portion of the applicable Advance as required. (f) NON-FUNDING CERTIFICATE HOLDER. In the event that any Certificate Holder (a "DEFAULTING CERTIFICATE HOLDER") fails to make available on a Funding Date an amount equal to such Certificate Holder's applicable Commitment Percentage (also a "DEFAULTED AMOUNT"), or Agent determines that a Certificate Holder will become a Defaulting Certificate Holder on the applicable Funding Date, Agent shall promptly notify Lessee thereof and Lessee shall have the option, except in respect of any Advance pursuant to the preceding paragraph (d) and without in any way waiving the occurrence of any Default, to postpone the funding of the entire Advance or the portion thereof representing the Defaulted Amount (provided, however, that such postponement shall in no event relieve Lessee of its obligation to pay as Supplemental Rent any Break Costs suffered or incurred by any Participant, but Lessee may offset any such costs against amounts otherwise payable by it, under the Operative Documents or otherwise, to the Defaulting Certificate Holder). Whether or not such option is exercised, Lessor or Agent may elect to have the Defaulting Certificate Holder replaced with a new Certificate Holder reasonably acceptable to Lessee and Agent and the Defaulting Certificate Holder shall cooperate (at the cost of the Defaulting Certificate Holder), in replacing such Defaulting Certificate Holder. Notwithstanding the existence of any Defaulting Certificate Holder, each other Certificate Holder (each, "NON-DEFAULTING CERTIFICATE HOLDER") shall timely fund its portion of the applicable Advance. (g) ADDITIONAL RIGHTS OF LESSEE. In the case of any Defaulted Amounts Lessee shall have the additional rights provided under Section 22. Participation Agreement 6

SECTION 4. YIELD; INTEREST; FACILITY FEES (a) YIELD. (i) The amount of the Equity Amounts outstanding from time to time shall accrue yield ("YIELD") at the Yield Rate, calculated using the actual number of days elapsed and, when the Yield Rate is determined by reference to the LIBO Rate (Reserve Adjusted) or the Alternate Base Rate not based upon the Prime Rate, a 360-day year basis and, when the Yield Rate is determined by reference to the Alternate Base Rate based upon the Prime Rate, a 365- (or, if applicable, 366-) day year basis. If all or any portion of the Equity Amounts, any Yield payable thereon or any other amount payable to any Certificate Holders, Lessor or Owner Trustee hereunder shall not be paid when due (whether at stated maturity, acceleration thereof or otherwise), such overdue amount shall bear interest at a rate per annum which is equal to the Overdue Rate. (i) The Lessee shall, pursuant to the Assignment of Leases and Rents, deposit in the Account the Equity Basic Rent (determined on the basis of accrued Yield due in accordance with clause (i) above) and all other amounts due with respect to the Equity Amounts payable by the Lessee under the Lease from time to time. (ii) During the Construction Period, subject to Section 4(c) and the terms and conditions set forth in this Participation Agreement with respect to Advances, Yield shall accrue on outstanding Equity Amounts and shall be funded monthly by the Lenders and the Certificate Holders pursuant to Section 3(a) and (b).

If all or any portion of the Loans, any interest payable thereon or any other amount payable to any Lender, or the Agent hereunder shall not be paid when due (whether at stated maturity, acceleration thereof or otherwise), such overdue amount shall bear interest at a rate per annum which is equal to the Overdue Rate. (ii) The Lessee shall, pursuant to the Assignment of Leases and Rents, deposit in the Account the Lender Basic Rent (determined on the basis of amounts due in accordance with clause (i) above) and all other amounts due with respect to the Loans payable by the Lessee under the Lease from time to time. (iii) During the Construction Period, subject to Section 4(c) and the terms and conditions set forth in this Participation Agreement with respect to Advances, interest shall accrue on outstanding Loans and shall be paid as an Advance in accordance with the Approved Budget.

(c) PREPAYMENTS OF LOANS AND EQUITY AMOUNTS. In the event that the Lessee pays the Property Balance to the Lessor in connection with the Lessee's purchase of the Property in accordance with Sections 6, 11 or 16 of the Lease, the Lessor will prepay the entire outstanding principal amount of the Loans and Equity Amounts (or portion thereof so paid in the case of Section 11 or 6(e) of the Lease). Each of the Participants and the Lessor hereby acknowledge that its Loans or Equity Amounts, as the case may be, may be so prepaid without any prepayment premium other than Break Costs and other amounts pursuant to Section 4(e)(iii). (d) FACILITY FEES; OTHER FEES. The Lessee agrees to pay the fees set forth in this Section 4(d); provided that during the Construction Period such fees shall be paid only out of the proceeds of an Advance in accordance with the Approved Budget, and shall not represent direct recourse obligations of the Lessee (except to the extent the Lessee is obligated to pay the Property Balance). (i) COMMITMENT FEES. The Lessee agrees to pay to each Tranche A Lender, each Tranche B Lender and each Certificate Holder for the Construction Period (including any portion of such Construction Period when any Participant's Commitment is suspended by reason of the Lessee's inability to satisfy any condition of Section 9), a facility fee (collectively, the "COMMITMENT FEES") at a per annum rate equal to the Applicable Facility Fee Percentage on each Participant's Available Commitment. The Commitment Fees shall be payable by the Lessee in arrears with respect to each monthly period (or portion thereof, for the first and last such periods) following the Documentation Date on the first day of each month (provided, however, that if such day is not a Business Day, such payment shall be due on the immediately preceding Business Day in the full amount due on such first day), commencing December 1, 2001 through and including the first day immediately following the expiration of the Construction Period, and shall be determined on the basis of the daily average Available Commitments during each such monthly period. The Commitment Fees shall be computed on the basis of the actual number of days (including the first day but excluding the last day) occurring during the period for which such Commitment Fees are payable over a year of 360 days. (ii) OTHER FEES. The Lessee agrees to pay the following fees in the amounts and at the times as provided in the Fee Letter and in accordance with the Approved Budget: (x) to the Agent, for its own account, the Annual Administration Fees, (y) to the Arranger, for its own account, the Arrangement Fee, and (z) to the Arranger, for its own account, the Structuring Fee; provided, that, during the Construction Period, such fees shall be paid from the proceeds of Advances. (e) INTEREST AND YIELD PROTECTION. (i) Alternate Rate of Interest. If prior to the commencement of any Interest Period for an Advance with interest or Yield determined by reference to the LIBO Rate (Reserve Adjusted): (1) the Agent determines (which determination shall be conclusive absent manifest error) that adequate and reasonable means do not exist for Participation Agreement 8

ascertaining the LIBO Rate (Reserve Adjusted) or the LIBO Rate, as applicable, for such Interest Period; or (2) the Agent is advised by any Participant or Participants that because of a change in circumstances affecting the eurocurrency market generally the LIBO Rate (Reserve Adjusted) or the LIBO Rate, as applicable, for such Interest Period will not adequately and fairly reflect the cost to such Participants (or Participant) of making or maintaining their Loans or Equity Amounts (or its Loan or Equity Amount) for such Interest Period; then the Agent shall give notice thereof to the Lessee and the Participants by telephone or telecopy as promptly as practicable thereafter and, until the Agent notifies the Lessee and the Participants that the circumstances giving rise to such notice no longer exist, (i) any Funding Request that requests the conversion or continuation of an Advance with interest determined by reference to the LIBO Rate (Reserve Adjusted) shall be ineffective, (ii) if any Funding Request requests an Advance with interest determined by reference to the LIBO Rate (Reserve Adjusted), such Advance shall be made as an Alternate Base Rate Advance and (iii) any Funding Request by the Lessee for an Advance with interest determined by reference to the LIBO Rate (Reserve Adjusted) shall be ineffective; provided, however, that if the circumstances giving rise to such notice do not affect all the Participants, then requests by the Lessee for an Advance with interest determined by reference to the LIBO Rate (Reserve Adjusted) may be made to Participants that are not affected thereby. (ii) Increased Costs. (1) If any Change in Law shall: (a) impose, modify or deem applicable any reserve, special deposit or similar requirement against assets of, deposits with or for the account of, or credit extended by, any Participant (except any such reserve requirement reflected in the LIBO Rate (Reserve Adjusted)); or (b) impose on any Participant or the London interbank market any other condition affecting this Agreement or Advances made by such Participant under this Agreement and the result of any of the foregoing shall be to increase the cost to such Participant of making, funding or maintaining any such Loan or Equity Amount (or of maintaining its obligation to make any such Loan or Equity Amount) or to reduce the amount of any sum received or receivable by such Participant hereunder (whether of principal, interest, Equity Amount, Yield or otherwise), then the Lessee will pay to such Participant such additional amount or amounts as will compensate such Participant for such additional costs incurred or reduction suffered. (2) If any Participant determines that any Change in Law regarding capital requirements has or would have the effect of reducing the rate of return on such Participant's capital or on the capital of such Participant's holding company, Participation Agreement 9

if any, as a consequence of this Agreement or the Loans or Equity Amounts made, funded or created by, such Participant, to a level below that which such Participant or such Participant's holding company could have achieved but for such Change in Law (taking into consideration such Participant's policies and the policies of such Participant's holding company with respect to capital adequacy), then from time to time the Lessee will pay to such Participant such additional amount or amounts as will compensate such Participant or such Participant's holding company for any such reduction suffered. (3) A certificate of a Participant setting forth the amount or amounts necessary to compensate such Participant or its holding company, as the case may be, as specified in paragraph (1) or (2) of this Subsection shall be delivered to the Lessee and shall be conclusive absent manifest error. The Lessee shall pay such Participant the amount shown as due on any such certificate within 10 days after receipt thereof. (4) Failure or delay on the part of any Participant to demand compensation pursuant to this Subsection shall not constitute a waiver of such Participant's right to demand such compensation; provided, however, that the Lessee shall not be required to compensate a Participant pursuant to this Subsection for any increased costs or reductions incurred more than three months prior to the date that such Participant notifies the Lessee of the Change in Law giving rise to such increased costs or reductions and of such Participant's intention to claim compensation therefor; provided further that, if the Change in Law giving rise to such increased costs or reductions is retroactive, then the three-month period referred to above shall be extended to include the period of retroactive effect thereof. (iii) Break Funding Payments. In the event of (1) the payment of any principal of any Loan or Equity Amount other than on the last day of an Interest Period applicable thereto (including as result of an Event of Default), (2) the conversion of any Loan or Equity Amount other than on the last day of the Interest Period applicable thereto, (3) the failure to borrow, convert, continue or prepay any Loan or Equity Amount on the date specified in any notice delivered pursuant hereto (regardless of whether such notice is permitted to be revocable and is revoked in accordance herewith), or (4) the assignment of any Loan or Equity Amount other than on the last day of the Interest Period applicable thereto as a result of a request by Lessee then, in any such event, the Lessee shall compensate each Participant for the loss, costs and expense attributable to such event, including, without limitation, Break Costs and any costs associated with the termination by any Participant of any foreign currency exchange arrangements. The loss to any Participant attributable to any such event shall be deemed to include an amount determined by such Participant to be equal to the excess, if any, of (i) the amount of interest that such Participant would pay for a deposit equal to the principal amount of such Loan or Equity Amount for the period from the date of such payment, conversion, failure or assignment to the last day of the then current Interest Period for such Loan (or, in the case of a failure to borrow, convert or continue, the duration of the Interest Period that would have resulted from such borrowing, conversion or continuation) if the interest Participation Agreement 10

rate payable on such deposit were equal to the LIBO Rate (Reserve Adjusted) for such Interest Period, over (ii) the amount of interest that such Participant would earn on such principal amount for such period if such Participant were to invest such principal amount for such period at the interest rate that would be bid by such Participant (or an Affiliate of such Participant) for dollar deposits from other banks in an eurodollar market at the commencement of such period. A certificate of any Participant setting forth any amount or amounts that such Participant is entitled to receive pursuant to this Subsection shall be delivered to the Lessee and shall be conclusive absent manifest error. The Lessee shall pay such Participant the amount shown as due on any such certificate within 10 days after receipt thereof. (1) Mitigation Obligations; Replacement of Participants. (1) If any Participant requests compensation under Section 4(e)(ii)(1), or if the Lessee is required to pay any additional amount thereunder to any Participant, then such Participant shall use reasonable efforts to designate a different lending office for funding or booking its Loans or Equity Amounts hereunder or to assign its rights and obligations hereunder to another of its offices, branches or affiliates, if, in the judgment of such Participant, such designation or assignment (i) would eliminate or reduce amounts payable pursuant to Section 4(e)(ii)(1) in the future and (ii) would not subject such Participant to any unreimbursed cost or expense and would not otherwise be disadvantageous to such Participant. The Lessee hereby agrees to pay all reasonable costs and expenses incurred by any Participant in connection with any such designation or assignment. (2) If any Participant requests compensation under Section 4(e)(ii) or if any Participant defaults in its obligation to fund Loans or Equity Amounts hereunder, then the Lessee may, at its sole expense and effort, upon notice to such Participant and the Agent, require such Participant to assign and delegate, without recourse, all its interests, rights and obligations under this Agreement to an assignee that shall assume such obligations (which assignee may be another Participant, if a Participant accepts such assignment); provided, however, that (i) the Lessee shall have received the prior written consent of the Agent, which consent shall not unreasonably be withheld, (ii) such Participant shall have received payment of an amount equal to the outstanding principal of its Loans or outstanding Equity Balance (as applicable), accrued interest or Yield thereon, accrued fees and all other amounts payable to it hereunder (including Break Costs), from the assignee (to the extent of such outstanding principal or Equity Balance and accrued interest or Yield and fees) or the Lessee (in the case of all other amounts) and (iii) in the case of any such assignment resulting from a claim for compensation under Section 4(e)(ii), such assignment will result in a reduction in such compensation or payments. A Participant shall not be required to make any such assignment and delegation if, prior thereto, as a result of a waiver by such Participant or otherwise, the circumstances entitling the Lessee to require such assignment and delegation cease to apply. (iv) If it becomes illegal for any Participant to continue its participation in the transaction contemplated by the Operative Documents (the "OVERALL TRANSACTION"), the Participation Agreement 11

Participant shall give notice promptly to the Agent, Certificate Holders, Owner Trustee, each other Participant and the Lessee (including in such notice reasonable details as to the basis of such illegality). Each Participant agrees for the benefit of the Lessee and (in the case of a Lender) the Certificate Holders, if so required by the Lessee, to consult in good faith with the Lessee and such other parties and to use its reasonable best efforts to avoid such illegality (including by assigning its rights hereunder and under the other Operative Documents to an Affiliate or branch of the Participant, and providing that such Affiliate or branch shall assume its obligations hereunder and thereunder); provided, however, that such Participant shall not in this connection be obligated to take any action which would be materially prejudicial to the operations of the Participant; provided further, however, that the portion of the Loan or Equity Amount held by such Participant shall be prepaid on or prior to the date (the "ILLEGALITY PREPAYMENT DATE") which is the earlier of the 180th day subsequent to the giving by such Participant of such notice and the date upon which the Participant is obligated under Applicable Law to terminate its participation in the Overall Transaction if such illegality has not been avoided or the portion of the Loan or Equity Amount held by such Participant has not been prepaid prior to the Illegality Prepayment Date. (v) During the Construction Period, any amounts payable pursuant to this Section 4(e) will be paid only from proceeds of the Advances in accordance with the Approved Budget; provided, that, in accordance with Section 14(a)(12) hereof, the Construction Agent has indemnified Lessor with respect to any such amounts or costs. (f) NOTICE OF YIELD AND INTEREST. (i) The Agent shall deliver to the Lessee from time to time written notice of the amount of Basic Rent and the due date therefor (i) promptly (and in any event within three (3) Business Days) after the commencement of each LIBO period, and (ii) promptly (and in any event within three (3) Business Days) after determination of Accrued Interest and Yield determined by reference to the Alternate Base Rate. (ii) During the Basic Term, subject to Section 4(e) hereof, on or before 10:00 a.m., Chicago time, on the date that is three (3) Business Days prior to the expiration of any Interest Period, Lessee shall, from time to time, upon written notice to the Lessor and the Agent, select whether or not interest and Yield will accrue at the Alternate Base Rate or the LIBO Rate. If Lessee's selects the LIBO Rate, Lessee shall also select the term of the next succeeding Interest Period. If Lessee does not specify the length of any Interest Period as set forth in the immediately preceding sentence, then Lessee shall be deemed to have a selected the then expiring Interest Period. During the Construction Period, the Lessee shall be allowed to maintain a maximum of two (2) separate LIBOR tranches at any time; provided, that only (1) LIBOR tranche shall exist upon the expiration of the Construction Period. During the Basic Term, the Lessee shall be allowed to maintain only one (1) LIBOR tranche. Participation Agreement 12

(1) If any Tax Indemnitee or any Affiliate of any Tax Indemnitee actually shall realize a Tax benefit (whether by way of deduction, credit, allocation or apportionment or otherwise) with respect to a Tax not indemnifiable hereunder which would not have been realized but for any Tax, Claim or other cost or expense with respect to which Lessee has reimbursed or indemnified such Tax Indemnitee on an After-Tax Basis pursuant to the Operative Documents, which benefit was not previously taken into account in determining the amount of the Lessee's payment to such Tax Indemnitee, such Tax Indemnitee shall pay to the Lessee, on an After-Tax Basis, an amount equal to the amount of such Tax benefit; provided, however, that no payment shall be made as long as a Payment Default or a Lease Event of Default is continuing; provided further, however, that no Tax Indemnitee shall be required to pay to the Lessee any Tax benefit to the extent such payment is greater than the amount of such Taxes, Claims, costs or expenses in respect of which the reimbursement or indemnification was paid by Lessee, reduced by all prior payments by such Tax Indemnitee under this Section 13(d) in respect of such amount; any payment to the Lessee which is so limited shall, to the extent of such unpaid excess, be carried over and shall be available to offset any future obligations of the Lessee under this Section 13). If such repaid Tax benefit is thereafter lost, the additional Tax payable shall be treated as a Tax indemnifiable hereunder without regard to the exclusions set forth in Section 13 (other than clause (c)(7)). (2) Upon receipt by a Tax Indemnitee of a refund or credit of all or part of any Taxes paid or indemnified against by the Lessee, which refund or credit was not previously taken into account in determining the amount of the Lessee's payment to such Tax Indemnitee, such Tax Indemnitee shall pay to the Lessee, on an After-Tax Basis, an amount equal to the amount of such refund, plus any interest received by or credited to such Tax Indemnitee with respect to such refund; provided, however, that no such payment shall be made as long as a Payment Default or a Lease Event of Default is continuing. (3) The Tax Indemnitee will, at the Lessee's expense, pursue refunds and tax benefits that would result in any such payments to the Lessee, but only if the Tax Indemnitee has been notified in writing by the Lessee that such refunds or tax benefits are available. (e) PROCEDURES. Any amount payable to a Tax Indemnitee pursuant to paragraph 13(b) shall be paid within thirty (30) days after receipt of a written demand therefor from such Tax Indemnitee accompanied by a written statement describing in reasonable detail the basis for such indemnity and the computation of the amount so payable, provided, however, that such amount need not be paid prior to the later of (i) the date on which such Taxes are due or (ii) in the case of amounts which are being contested pursuant to paragraph 13(f) hereof, the time Participation Agreement 56

such contest (including all appeals permitted hereunder) is finally resolved; provided, further, that with respect to Taxes of a recurring nature, the Tax Indemnitee shall only be required to provide one such written notice. Any amount payable to the Lessee pursuant to paragraph 13(d) shall be paid within twenty (20) days of the day on which a return (including estimated tax returns) is filed reflecting such Tax benefit or promptly after the Tax Indemnitee actually receives a refund giving rise to a payment under paragraph 13(d), and shall be accompanied by a written statement by the Tax Indemnitee setting forth in reasonable detail the basis for computing the amount of such payment. Within thirty (30) days following the Lessee's receipt of any computation from the Tax Indemnitee, the Lessee may request that an accounting firm reasonably acceptable to the Lessee determine whether such computations of the Tax Indemnitee are correct. Such accounting firm shall be requested to make the determination contemplated by this paragraph 13(e) within thirty (30) days of its selection. In the event such accounting firm shall determine that such computations are incorrect, such firm shall determine what it believes to be the correct computations. The Tax Indemnitee shall cooperate with such accounting firm and supply it with all information necessary to permit it to accomplish such determination. The computations of such accounting firm shall be final, binding and conclusive upon the parties and the Lessee shall have no right to inspect the books, records or tax returns of the Tax Indemnitee to verify such computation or for any other purpose. All fees and expenses of the accounting firm payable under this Section 13(e) shall be borne by the Lessee, except that if such accounting firm's computation shall result in a decrease in the amount due from, or an increase in the amount payable to, the Lessee by more than the greater of 5% of the amount claimed by the Tax Indemnitee or $10,000, then the Tax Indemnitee shall bear the cost of such accounting firm. (f) CONTEST. If any claim shall be made against any Tax Indemnitee or if any proceeding shall be commenced against any Tax Indemnitee (including a written notice of such proceeding) for any Tax as to which the Lessee may have an indemnity obligation, or if any Tax Indemnitee shall determine that any Tax as to which the Lessee may have an indemnity obligation may be payable, such Tax Indemnitee shall promptly notify the Lessee in writing and shall not take any action with respect to such claim, proceeding or Tax without the consent of the Lessee for thirty (30) days after receipt of such notice by the Lessee unless the failure to take action could result in the imposition of penalties or fines or material danger of sale, forfeiture or loss of, or the creation of any Lien on, the Platform or the Property or any portion thereof or interest therein; provided, however, that any failure to provide such notice shall not relieve the Lessee of any obligation to indemnify any Tax Indemnitee hereunder unless the Lessee is materially adversely affected as a result of such failure and such failure arises out of or is caused by the misconduct or negligence (excluding imputed negligence) of such Tax Indemnitee; provided, further, however, that if such Tax Indemnitee shall be required by law or regulation to take action with respect to any such claim, proceeding or Tax prior to the end of such thirty (30) day period such Tax Indemnitee shall, in such notice to the Lessee, so inform the Lessee and such Tax Indemnitee shall not take any action with respect to such claim, proceeding or Tax without the consent of the Lessee before the date on which such Tax Indemnitee shall be required to take action. If, within thirty (30) days after its receipt of such notice (or such shorter period referred to in the preceding sentence), the Lessee shall request in writing that such Tax Indemnitee contest the imposition of such Tax, the Tax Indemnitee shall, at the expense of the Lessee, in good faith contest (including by pursuit of appeals, excluding any requirement to appeal to the U.S. Supreme Court), and shall not settle without the Lessee's consent, or if such contest can be pursued independently from any other proceeding involving a Tax liability of such Participation Agreement 57

The party in control of any contest shall consult in good faith and cooperate with the other party regarding the conduct of any contest and the Tax Indemnitee shall allow the Lessee to attend all hearings at which unrelated issues are not discussed and to comment upon all related submissions in such Tax Indemnitee-controlled contests and vice versa. Notwithstanding the above, a Tax Indemnitee may settle and will not be required to contest the imposition of any Taxes if such Tax Indemnitee shall waive its right to indemnity with respect to such Taxes and all future related Taxes and shall have paid to the Lessee any and all funds paid by the Lessee to such Tax Indemnitee with regard to such contested amount (other than those described in clause (x) of this Section 13(f)) plus any Participation Agreement 58

interest which the Lessee paid on such funds. Any contest by the Lessee or at the Lessee's request shall be subject to the following requirements: (i) such contest shall be conducted in good faith by appropriate proceedings which have the effect of staying the enforcement of the lien for such Taxes and the sale, forfeiture or other loss of the Platform during the pendency of such contest, (ii) none of the Lessor, the Owner Trustee, the Agent and the Participants shall be subject to any risk of criminal liability or material civil liability by virtue of the matters being contested or such proceedings, and (iii) the Lessee, in accordance with prudent practice, has set aside adequate reserves for the payment thereof and has provided evidence reasonably acceptable to the Agent, the Lessor and the Participants of such reserves. (g) REPORTS. In the event any report, return or statement or any certification or procedure (a "FILING") with respect to Taxes is required to be made with respect to any Tax that may be subject to indemnification under this Section 13, the Lessee will, at the Lessee's expense, either prepare and file such Filing or, if it shall not be permitted to file the same, it will notify each Tax Indemnitee of such reporting requirements, prepare such Filing in such manner as shall be reasonably satisfactory to each Tax Indemnitee and deliver the same to each Tax Indemnitee within a reasonable period prior to the date the same is to be filed; provided, however, that the relevant Tax Indemnitees shall have furnished the Lessee, at the Lessee's request and expense, within a reasonable time, with such information, not within the control of (nor reasonably available to) the Lessee, in such Tax Indemnitee's control (or which is reasonably available to such Tax Indemnitee) and is necessary to complete such Filing. (h) NON-PARTIES. If a Tax Indemnitee is not a party to this Agreement, Lessee may require the Tax Indemnitee to agree in writing, in a form reasonably acceptable to Lessee, to the terms of this Section 13 prior to making any payment to such Tax Indemnitee under this Section 13. (i) SURVIVAL. The provisions of this Section 13 shall continue in full force and effect, notwithstanding the expiration or termination of any Operative Document, until all obligations hereunder have been met and all liabilities hereunder paid in full. (j) CONSTRUCTION PERIOD. Notwithstanding the foregoing, during the Construction Period, (i) the Lessor, in lieu of the Lessee, shall indemnify all Lender Indemnitees under this Section 13, to the same extent that the Lessee is obligated to so indemnify such parties absent the provisions of this subsection (j), (ii) the Lessee will indemnify the Lessor for all obligations of the Lessor under this subsection (j), and (iii) the Lessor hereby assigns to each of the Lender Indemnitees the Lessor's right to indemnification by the Lessee under this subsection (j) to the extent of any claim by the respective Lender Indemnitee under this Section 13. Any indemnification by the Lessor shall be subject to all of the provisions of this Section 13 to the same extent as applicable to indemnification by the Lessee under this Section 13. SECTION 14.

If a Claim indemnified by Lessee under this Section 14 is paid in full by Lessee and/or an insurer under a policy of insurance maintained by Lessee, or if payment of the Claim has otherwise been provided for in full in a manner reasonably satisfactory to the Indemnified Person, Lessee and/or such insurer, as the case may be, shall be subrogated to the extent of such payment (or provision) to the rights and remedies of the Indemnified Person (other than under insurance policies maintained by such Indemnified Person) on whose behalf such Claim was paid (or provided for) with respect to the act or event giving rise to such Claim. So long as no Payment Default and no Lease Event of Default exists, if an Indemnified Person receives any refund, in whole or in part, with respect to any Claim paid by Lessee hereunder, it shall promptly pay over the amount refunded (but not in excess of the amount Lessee or any of its insurers has paid in respect of such Claim paid or payable by such Indemnified Person on account of such refund) to Lessee; provided, however, if any Payment Default or Lease Event of Default exists, any such refund shall be retained by, or paid over to, the Lessor to be held and applied against amounts payable by the Lessee hereunder and under the other Operative Documents. (f) INSURED CLAIMS. In the case of any Claim indemnified by the Lessee hereunder which is covered by a policy of insurance maintained by or for the benefit of the Lessee, each Indemnified Person agrees to cooperate, at the expense of the Lessee, with the insurers in the exercise of their rights to investigate, defend or compromise such Claim as may be required to retain the benefits of such insurance with respect to such Claim (but the failure to do so shall not relieve the Lessee of its obligation to indemnify such Indemnified Person except to the extent that the Lessee or its insurer is materially prejudiced as a result of such failure). (g) WAIVER OF CERTAIN CLAIMS. Lessee hereby waives and releases any Claim now or hereafter existing against any Indemnified Person out of death or personal injury to personnel of Lessee (including its directors, officers, employees, agents and servants), loss or damage to property of Lessee or its Affiliates, of the loss of use of any property of Lessee or its Affiliates, which may result from or arise out of the condition, use or operation of the Platform or the Property during the Lease Term and the Renewal Term, if any, including, without limitation, any latent or patent defect whether or not discoverable.

The obligations of the Participants under this Section 21(h) shall survive payment of the Obligations and termination of this Participation Agreement. (i) NOTICE OF DEFAULT. The Agent shall not be deemed to have knowledge or notice of the occurrence of any Default or Event of Default hereunder unless the Agent has received written notice from a Participant or the Lessee referring to this Agreement describing such Default or Event of Default and stating that such notice is a "notice of default". In the event that the Agent receives such a notice, the Agent shall give prompt notice thereof to the Participants. (j) RIGHTS AS A PARTICIPANT. In the event the Agent is a Participant, the Agent shall have the same rights and powers hereunder and under any other Operative Document with respect to its Commitment and its Loans as any Participant and may exercise the same as though it were not the Agent, and the term "Participant" or "Participants" shall, at any time when the Agent is a Participant, unless the context otherwise indicates, include the Agent in its individual capacity. The Agent and its Affiliates may accept deposits from, lend money to, and generally engage in any kind of trust, debt, equity or other transaction, in addition to those contemplated by this Agreement or any other Operative Document, with the Lessee or any of its Subsidiaries in which the Lessee or such Subsidiary is not restricted hereby from engaging with any other Person. The Agent, in its individual capacity, is not obligated to remain a Participant. (k) PARTICIPANT CREDIT DECISION. Each Participant acknowledges that it has, independently and without reliance upon the Agent, the Arranger or any other Participant and based on the financial statements prepared by the Lessee and such other documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Participation Agreement and the other Operative Documents. Each Participant also acknowledges that it will, independently and without reliance upon the Agent, the Arranger or any other Participant and based on such documents and information as it shall deem appropriate at the time, continue to make its own credit decisions in taking or not taking action under this Participation Agreement and the other Operative Documents. (l) SUCCESSOR AGENT. The Agent may resign at any time by giving written notice thereof to the Participants and the Lessee, such resignation to be effective upon the appointment of a successor Agent or, if no successor Agent has been appointed, forty-five days after the retiring Agent gives notice of its intention to resign (subject, during the Construction Period, to the consent of the Lessee unless a Lease Event of Default or Payment or Bankruptcy Default shall have occurred and be continuing). The Agent may be removed at any time with or without cause by written notice received by the Agent from the Required Participants, such removal to be effective on the date specified by the Required Participants. Upon any such resignation or removal, the Required Participants shall have the right to appoint, on behalf of the Lessee and the Participants, a successor Agent. If no successor Agent shall have been so appointed by the Participation Agreement 71

Required Participants within thirty days after the resigning Agent's giving notice of its intention to resign, then the resigning Agent may appoint, on behalf of the Lessee and the Participants, a successor Agent. Notwithstanding the previous sentence, the Agent may at any time without the consent of the Lessee or any Participant, appoint any of its Affiliates which is a commercial bank as a successor Agent hereunder. If the Agent has resigned or been removed and no successor Agent has been appointed, the Participants may perform all the duties of the Agent hereunder and the Lessee shall make all payments in respect of the Obligations to the applicable Participant and for all other purposes shall deal directly with the Participants. No successor Agent shall be deemed to be appointed hereunder until such successor Agent has accepted the appointment. Any such successor Agent shall be a commercial bank having capital and retained earnings of at least $100,000,000. Upon the acceptance of any appointment as Agent hereunder by a successor Agent, such successor Agent shall thereupon succeed to and become vested with all the rights, powers, privileges and duties of the resigning or removed Agent.

After the effectiveness of the resignation or removal of an Agent, the provisions of this Section 21 shall continue in effect for the benefit of such Agent in respect of any actions taken or omitted to be taken by it while it was acting as the Agent hereunder and under the other Operative Documents. In the event that there is a successor to the Agent by merger, or the Agent assigns its duties and obligations to an Affiliate pursuant to this Section 21(l), then the term "Prime Rate" as used in this Agreement shall mean the prime rate, base rate or other analogous rate of the new Agent. (m) AGENT'S FEE. The Lessee agrees to pay to the Agent, for its own account, the fees agreed to by the Lessee and the Agent pursuant to the Fee Letter and the Agent's reasonable fees, costs and expenses for the performance of Agent's obligations hereunder; provided, that during the Construction Period such fees, costs and expenses shall be paid only out of proceeds of an Advance in accordance with the Approved Budget and such amounts shall not, during the Construction Period, represent direct recourse obligations of the Lessee. (n) DELEGATION TO AFFILIATES. The Lessee and the Participants agree that the Agent may delegate any of its duties under this Participation Agreement to any of its Affiliates. Any such Affiliate (and such Affiliate's directors, officers, agents and employees) which performs duties in connection with this Agreement shall be entitled to the same benefits of the indemnification, waiver and other protective provisions to which the Agent is entitled under Section 13 and 14. (o) EXECUTION OF COLLATERAL DOCUMENTS.

(i) HIGHEST LAWFUL RATE. (i) It is the intention of the parties hereto to conform strictly to applicable usury laws and, anything herein to the contrary notwithstanding, the obligations of (x) Lessee to Certificate Holders under this Agreement and the Lease, (y) Owner Trustee to the Certificate Holders under the Trust Agreement and the Certificates and to the Lenders under the Loan Agreement and the Notes and (z) either Lessee, Lessor or Owner Trustee or any other party under any other Operative Documents, shall be subject to the limitation that payments of interest or of other amounts constituting interest under applicable law shall not be required to the extent that receipt thereof would be in excess of the Highest Lawful Rate (as defined below), or otherwise contrary to provisions of law applicable to the recipient limiting rates of interest which may be charged or collected by the recipient. Accordingly, if the transactions or the amount paid or otherwise agreed to be paid for the use, forbearance or detention of money under this Participation Agreement, the Lease, the Trust Agreement, the Certificates, the Loan Agreement, the Notes or any other Operative Document would exceed the Highest Lawful Rate or otherwise be usurious under Applicable Law (including without limitation the federal and state laws of the United States of America, or of any other jurisdiction whose laws may be mandatorily applicable) with respect to the recipient of any such amount, then, in the event, notwithstanding anything to the contrary in this Participation Agreement, the Lease, the Trust Agreement, the Certificates, the Loan Agreement, the Notes or any other Operative Document, it is agreed at followings as to the recipient of any such amount: (ii) the provisions of this Section 23(l) shall govern and control over any other provision in this Participation Agreement, the Lease, the Trust Agreement, the Certificates, the Loan Agreement, the Notes or any other Operative Document and each provision set forth therein is hereby so limited; (iii) the aggregate of all consideration which constitutes interest under Applicable Law that is contracted for, charged or received under this Participation Agreement, the Lease, the Trust Agreement, the Certificates, the Loan Agreement, the Notes or any other Operative Documents shall under no circumstances exceed the maximum amount of interest allowed by Applicable Law (such maximum lawful interest rate, if any, with respect to such recipient herein called the "HIGHEST LAWFUL RATE"), and all amounts owed under this Participation Agreement, the Lease, the Trust Agreement, the Certificates, the Loan Agreement, the Notes or any other Operative Document shall be held subject to reduction and (i) the amount of interest which would otherwise be payable to the recipient hereunder and under the Lease, the Trust Agreements, the Certificates, the Loan Agreement, the Notes and any other Operative Documents, shall be automatically reduced to the amount allowed under Applicable Law and (ii) any unearned Participation Agreement 76

interest paid in excess of the Highest Lawful Rate shall be credited to the payor by the recipient (or, if such consideration shall have been paid in full, refunded to the payor); (iv) all sums paid, or agreed to be paid for the use, forbearance and detention of the money under this Participation Agreement, the Lease, the Trust Agreement, the Certificates, the Loan Agreement, the Notes or any other Operative Documents shall, to the extent permitted by Applicable Law, be amortized, prorated, allocated and spread throughout the full term of such indebtedness until payment in fill so that the actual rate of interest is uniform throughout the full term thereof; (v) if at any time the interest, together with any fees, late charges and other sums payable pursuant to or in connection with this Participation Agreement, the Lease, the Trust Agreement, the Certificates, the Loan Agreement, the Notes or any other Operative Document, and deemed interest under Applicable Law, exceeds that amount which would have accrued at the Highest Lawful Rate, the amount of interest any such fees, charges and sums to accrue to the recipient of such interest, fees, charges and sums pursuant to the Operative Documents shall be limited, notwithstanding anything to the contrary in the Operative Documents to that amount which would have accrued at the Highest Lawful Rate for the recipient, but any subsequent reductions, as applicable, shall not reduce the interest to accrue pursuant to the Operative Documents below the recipient's Highest Lawful Rate until the total amount of interest payable to the recipient (including all considerations which constitute interest) equals the amount of interest which would have been payable to the recipient (including all consideration which constitutes interest) plus the amount of fees which would have been received but for the effect of this Section 23(l). (l) ACCOUNTING CHANGES. Although neither Lessor, the Agent, any Certificate Holder, nor any Lender makes any representation or warranty with respect to the Lessee's accounting treatment of this transaction, in the event that Lessee shall determine that any change in the applicable rules and interpretations of the Financial Accounting Standards Board and/or the Securities Exchange Commission (the "LEASE ACCOUNTING RULES") will preclude the Lessee (or raise a substantial question as to whether the Lessee is precluded) from continuing to account for this Lease as an operating lease with substantially the same financial accounting benefits as before the change in Lease Accounting Rules, then the Lessee shall so notify the Lessor and the Agent in writing of such determination; and (i) Lessee may attempt to renegotiate the structure of the transaction contemplated by the Operative Documents (provided that nothing contained in this Section 23(m) shall require any Person to agree to any new structure); or (ii) Lessee may elect (by delivery of irrevocable written notice of such election to the Lessor and the Agent) to purchase all of the Property or to cause all of the Property to be transferred to a third party transferee designated by Lessee (such purchase or transfer to be consummated on a date (the "ACCOUNTING CHANGE TRANSFER DATE") specified by Lessee in such notice and in any event within sixty (60) days after the date of such notice). On the Accounting Change Transfer Date (whether the Property is to be purchased by Lessee or transferred to a third party), Lessee shall pay or cause to be paid to Lessor an amount equal to the Property Balance. Upon receipt of such amount, Lessor shall transfer to Lessee (or to the third party designated by Lessee) all of Lessor's right, title and interest in and to the Property in accordance with the Transfer Protocol and the Expiration Date shall be deemed to have occurred on the date of such transfer. Participation Agreement 77

Notwithstanding any other provision to the contrary contained in the Operative Documents and subject to the fulfillment of each of the conditions set forth in Section 24(a) below, Lessee shall have the one (1) time option (the "Partial Purchase Option") to cause to be purchased by a third party purchaser which is not an Affiliate of the Lessee (the "Partial Option Purchaser") up to (but not more than) 50% of the Property for an amount equal to the portion (expressed as a percentage of the Property) (the "Partial Option Percentage") of the Property that Lessee has elected to purchase pursuant to the Partial Purchase Option (the "Partial Option Property") multiplied by the Property Balance as of Partial Option Closing Date (the "Partial Option Purchase Price"). (a) The Lessee's effective exercise and consummation of the Partial Purchase Option shall be subject to the due and timely fulfillment of each of the following conditions: (i) The Lessee shall provide the Agent with a written notice of its election to exercise the Partial Purchase Option which notice shall specify (x) the date (the "Partial Option Closing Date") upon which the Partial Purchase Option is expected to be consummated (the "Partial Option Closing"); (y) the identity of the Partial Option Purchaser; and (z) the Partial Option Property; provided, that (i) the Partial Purchase Option must be consummated prior to the date that is 365 days prior to the Lease Termination Date; and (ii) the Partial Option Closing Date shall not be less than thirty (30) days nor more than ninety (90) days after the date that Agent receives Lessee's written notice of its election to exercise the Partial Purchase Option; (ii) No Event of Default or Default shall exist on the date of the exercise of the Partial Purchase Option, and no Default or Event of Default shall exist at any time between the date of such exercise and the Partial Option Closing; (iii) The Lessee shall have provided to the Agent a true, correct and complete copy of the agreement of purchase and sale (the "Partial Option Purchase Agreement"), pursuant to which Lessee has agreed to cause to be sold to the Partial Option Purchaser and such Partial Option Purchaser has agreed to purchase, the Partial Option Property; (iv) The Lessee shall have provided the Agent with evidence that Kerr-McGee and Nexen Petroleum Offshore U.S.A., Inc. have each consented to (i) the Partial Option Purchase Agreement and the transaction contemplated by the Partial Option Purchase Agreement and (ii) the admission of the Partial Option Purchaser as a party to the Joint Operating Agreement; (v) The Lessee shall have paid or caused to be paid to the Agent (for distribution pursuant to Section 5(d)(xi)), out of Lessee's or the Partial Option Purchaser's funds (and not from Advances), the sum of (x) the Partial Option Purchase Price, (y) all Excluded Amounts and (z) all costs and expenses incurred by the Agent, the Lessor, the Owner Trustee and the Participants in connection with the Partial Option Closing and the preparation, execution and delivery of the documents evidencing Partial Purchase Option transaction (including the matters described in Section 24(a)(vi) and Section 24(b), including, all reasonable attorneys' fees and expenses incurred in connection with such transaction; and Participation Agreement 78

(vi) The Lessee shall have provided the Agent with such other documents, instruments, information, agreements, consents, opinions of counsel and assurances, including, without limitation, any amendments to the Joint Operating Agreement or any of the Construction Documents, as may from time to time be reasonably requested by the Agent in connection with the Partial Purchase Option. (b) Subject to the satisfaction of each of the conditions set forth in Section 24(a), at the Closing, the Lessor shall transfer to the Partial Option Purchaser by a quitclaim bill of sale, all of the Lessor's right, title and interest in and to the Partial Option Property on an "as is" "where is" and "with all faults" basis, without representation or warranty. Lessor and the Agent, as appropriate, shall also execute and deliver any appropriate and required partial releases of the Liens of (v) the Assignment of Leases and Rents, (w) the Lender Mortgage, (x) the Memorandum of Lease, (y) related UCC Financing Statements and (z) such other Operative Documents as Lessee shall reasonably require. Each of the foregoing documents and instruments shall be acceptable, in form and substance, to the Lessor and the Agent. (c) Lessee acknowledges and agrees that if for any reason the Partial Purchase Option Closing is not consummated on the Partial Option Closing Date then, the portion of the Property Balance equal to the Partial Option Purchase Price will accrue interest or Yield, as the case may be, at the Alternate Base Rate until such time as Lessee elects or is otherwise able to convert such rate of interest or Yield to the LIBO Rate pursuant to the Operative Documents. SECTION 25. SALE OF WORKING INTEREST. Lessee covenants and agrees that it shall not directly or indirectly sell, convey, assign, transfer, encumber, or alienate all or any portion of its Working Interest (as defined in the Joint Operating Agreement); provided, that: (a) Lessee may sell a portion of its Working Interest to the Partial Option Purchaser in conjunction with the consummation of the Partial Purchase Option under Section 24 of this Participation Agreement (it being understood and agreed that Lessee shall only be entitled to sell to the Partial Option Purchaser a percentage of its Working Interest that is equal to and in the same proportion as the Partial Option Percentage); and (b) Lessee may sell its Working Interest contemporaneously with its purchase of the Property pursuant to Section 6(e) of the Lease.

THIS CREDIT AGREEMENT, dated as of August __, 2000 is made by and among CAL DIVE I - TITLE XI, INC., a Texas corporation (the "Shipowner"), GOVCO INCORPORATED, a Delaware corporation (the "Primary Lender"), CITIBANK, N.A., a national banking association (the "Alternate Lender"), CITIBANK INTERNATIONAL plc, a bank organized and existing under the laws of England, as facility agent for both the Primary Lender and the Alternate Lender (and their respective successors and assigns) with respect to the Floating Rate Note, and its permitted successors and assigns (in such capacity, the "Facility Agent"), and CITICORP NORTH AMERICA, INC., a Delaware corporation, as administrative agent for the Primary Lender and the commercial paper holders of the Primary Lender (and their respective successors and assigns) (in such capacity, together with its permitted successors and assigns, the "Administrative Agent," and together with the Facility Agent, the "Agents"). As used herein, the term "Lender" shall mean either the Primary Lender or the Alternate Lender, as the case may be, depending on which of the two parties made or will make the relevant disbursement of funds under this Agreement; provided, however, that if the Primary Lender assigns its rights under this Agreement to the Alternate Lender, the term "Lender," as used herein, shall mean only the Alternate Lender. The term "Lenders," as used herein, shall mean collectively the Primary Lender and the Alternate Lender. BACKGROUND WHEREAS: (A) by this Agreement, the Lenders have established a credit facility (the "Credit Facility") in the amount of $138,478,000, pursuant to which the Primary Lender may, in its discretion, subject to the terms and conditions hereof, extend financing to the Shipowner (i) for the manufacture, construction, fabrication, financing and purchase by the Shipowner of the Vessel; (ii) for the payment of the related Construction Period Interest; and (iii) for the payment of the Guarantee Fees; (B) the establishment of the Credit Facility is in reliance upon the commitment of the United States to guarantee the payment of the unpaid interest on, and the unpaid balance of the principal of, the Floating Rate Note, including interest accruing between the date of an Indenture Default under the Floating Rate Note and the payment in full of the Guarantee; (C) a condition to the Lenders' extension of the Credit Facility under this Agreement is the Facility Agent's timely receipt of Certificates Authorizing Disbursement and issuance of the Guarantee of the Floating Rate Note; (D) the Facility Agent will serve as facility agent for the benefit, and on behalf, of each of the Lenders in connection with the Credit Facility, this Agreement and the other related documents and the Administrative

Agent will act as an administrative agent for the Primary Lender and the Primary Lender's commercial paper holders; and (E) the Credit Facility may be utilized by the Shipowner in accordance with the terms and conditions of this Agreement. NOW, THEREFORE, in consideration of the premises and the mutual covenants herein contained, the parties hereto agree as follows: SECTION 1. DEFINITIONS AND PRINCIPLES OF CONSTRUCTION 1.01 Defined Terms. For the purposes of this Agreement, unless otherwise defined herein, defined terms shall have the meanings specified in Exhibit 1 hereto. 1.02 Principles of Construction. (a) The meanings set forth for defined terms in this Agreement shall be equally applicable to both the singular and plural forms of the terms defined. (b) Unless otherwise specified, all references in this Agreement to Annexes or Exhibits are to Annexes or Exhibits in or to this Agreement. (c) The headings of the Sections in this Agreement are included for convenience only and shall not in any way affect the meaning or construction of any provision of this Agreement. SECTION 2. THE CREDIT FACILITY 2.01 Amount. The Lenders hereby establish the Credit Facility, upon the terms and conditions set forth in this Agreement, in favor of the Shipowner in the maximum amount of $138,478,000 (the "Credit Facility Amount"), to enable the Shipowner to finance: (i) the manufacture, construction, fabrication, financing and purchase of the Vessel; (ii) Construction Period Interest; and (iii) the Guarantee Fees; all as set forth in Certificates Authorizing Disbursements submitted in accordance with this Agreement. The Primary Lender intends (but is not obligated) to fund the Credit Facility through the issuance and sale of Commercial Paper to investors which is exempt from the registration requirements of the United States Securities Act of 1933, as amended. The Primary Lender may, at its option, elect at any time not to fund the Credit Facility or the undisbursed portion thereof, in which case the Alternate Lender shall, subject to the terms and conditions provided herein, fund the Credit Facility in the amount (the "Available Amount") which is equal to the excess, if any, of the Credit Facility Amount over the outstanding principal amount evidenced by the Floating Rate Note, plus the aggregate outstanding principal amount evidenced by Fixed Rate Bonds ("Outstanding Principal"). 2

2.02 Availability. Disbursements under the Credit Facility may be made once a calendar month and up to and including the Final Disbursement Date. "Final Disbursement Date" shall mean the earliest of (x) January 28, 2002, (y) the date upon which the Trigger Event (as defined in Section 2.05) shall occur or, (z) the date on which the Available Amount under the Credit Facility is canceled in accordance with Section 9.01 or reduced to zero. 2.03 Disbursements and Minimum Amount of Utilizations. Upon satisfaction of Sections 3.01, 5.01 and 5.02, disbursements shall be made by advances from the Primary Lender or the Alternate Lender to the Shipowner ("Disbursements") in accordance with Section 3.01. Notwithstanding anything in this Agreement to the contrary, the Shipowner may not request a Disbursement under the Credit Facility for an amount (a) less than the smaller of (i) $1,000,000 or (ii) the Available Amount or (b) more than the Available Amount. 2.04 Relationship of Floating Rate Note and Fixed Rate Bond(s). Disbursements from the Credit Facility shall become the indebtedness of the Shipowner to the Lenders under the Floating Rate Note. The Shipowner shall redeem the Floating Rate Note in full by causing to be issued one or more Fixed Rate Bonds and using the proceeds thereof to repay the Floating Rate Note in full no later than the earliest of (i) the Payment Date next preceding four years from the Delivery Date, (ii) January 28, 2006, or (iii) the date upon which the Trigger Event shall occur. At its option, and from time to time, the Shipowner may redeem all or any portion of the indebtedness under the Floating Rate Note by causing a Fixed Rate Bond or series of Fixed Rate Bonds to be issued at any time during or after the construction of the Vessel, so long as such redemption of the Floating Rate Note does not occur later than the earliest of (i) the Payment Date next preceding four years after the Delivery Date, (ii) January 28, 2006, or (iii) the date upon which the Trigger Event shall occur, and except for the final redemption or in the case of the Trigger Event, each redemption is in a minimum amount of $50,000,000; and the Shipowner shall have paid any amount payable under Section 4.04(a)(iv) or any other provision hereof in connection therewith. 2.05 Trigger Event. (a) The Shipowner shall redeem the Floating Rate Note in full by causing to be issued one or more Fixed Rate Bonds with a Maturity date no later than (i) January 28, 2027, or (ii) the twenty fifth anniversary of the Delivery Date upon the occurrence of a Trigger Event. A "Trigger Event" shall mean (x) three hundred and sixty five (365) days from the date when the ten (10) year Treasury constant maturity rate as reported by the Federal Reserve Board in statistical release H.15 (519) (the "Treasury Rate") first equals or exceeds eleven percent (11%) per annum, or (y) fifteen (15) Business Days from the date at any time during said three hundred and sixty five (365) day period when the Treasury Rate first equals or exceeds twelve percent (12%) per annum; provided however, that in the event interest rates have improved at the end of said three hundred and sixty five (365) day period, the Shipowner may request the Secretary, at that 3

time, to extend the three hundred and sixty five (365) day period, and the Secretary, in his sole discretion, may grant or deny such request. If a Trigger Event should occur, the Shipowner shall redeem the Floating Rate Note in full by causing to be issued one or more Fixed Rate Bonds and using the proceeds thereof to repay the Floating Rate Note in full. (b) Nothing in this Section 2.05 shall prevent the Shipowner from redeeming the Floating Rate Note by issuance of a fixed-rate obligation at any time prior to maturity, including without limitation, the three hundred and sixty five (365) day period referred to in Section 2.05(a). (c) The failure of the Shipowner to redeem the Floating Rate Note and to borrow the Available Amount by issuance of a fixed-rate obligation pursuant to this Section 2.05, unless subsequently waived in writing by the Secretary, shall constitute an Indenture Default without further notice to the Shipowner or the Lenders being required under the Indenture or this Agreement. (d) The Shipowner covenants for the benefit of the Secretary that it shall arrange for an independent reporting service or bank acceptable to the Secretary to send the Secretary, the Facility Agent, and the Shipowner a written interest rate report once a month on the first business day of every month (until such time as the Floating Rate Note is prepaid in full by a fixed rate obligation). This interest rate report shall specify the Treasury Rate as of the date of the report. SECTION 3. DISBURSEMENT REQUIREMENTS 3.01 Disbursement Procedures. Upon receipt by the Facility Agent of each Certificate Authorizing Disbursement at least five (5) Business Days prior to the proposed disbursement date, the Primary Lender may, and if the Primary Lender elects not to, the Alternate Lender shall, disburse funds in accordance with the terms of such Certificate Authorizing Disbursement to the Shipowner, or the Shipowner's designee, subject to the terms of this Agreement and such Certificate Authorizing Disbursement; provided that, if the Certificate Authorizing Disbursement and the request for disbursement referred to therein do not specify a disbursement date, then the disbursement date shall be the fifth Business Day (or such earlier or later Business Day as is requested by the Shipowner and is acceptable to the disbursing Lender) following the Facility Agent's receipt of such Certificate Authorizing Disbursement. Promptly following each Disbursement, the Facility Agent shall transmit to the Indenture Trustee and the Shipowner a copy of the Certificate Authorizing Disbursement, a confirmation that the Disbursement was made, and a copy of Exhibit A to the Floating Rate Note, updated to reflect such Disbursement and other intervening, related events. 4

SECTION 4. TERMS OF THE CREDIT 4.01 Principal Repayment. The Shipowner shall repay the Outstanding Principal of the Floating Rate Note as follows: (i) in installments in the principal amounts set forth in the Amortization Schedule, Attachment 1 to the Indenture, on each Payment Date commencing with the Payment Date occurring on the earlier of the Payment Date next succeeding the Delivery Date of the Vessel or January 28, 2002, and continuing until the Payment Date before the earlier of (x) the Payment Date next preceding four years from the Delivery Date, or (y) January 28, 2006, and (ii) the full amount of remaining Outstanding Principal, on the earliest of (x) the Payment Date next preceding four years from the Delivery Date, (y) January 28, 2006, or (x) the date upon which the Trigger Event shall occur. 4.02 Interest Payment. (a) On each Interest Payment Date, the Shipowner shall pay to the Indenture Trustee, on behalf of the Person(s) entitled thereto, interest on the Outstanding Principal in arrears, calculated at an interest rate per annum equal to the Applicable Interest Rate therefor, as determined for each successive Interest Period. The Indenture Trustee shall calculate the Applicable Interest Rate based on information provided (i) by the Administrative Agent to the Facility Agent if the Primary Lender is the Lender, or (ii) by the Facility Agent if the Alternate Lender is the Lender. From time to time, the Administrative Agent or Facility Agent will confirm CP Rate, LIBOR, Base Rate, and Applicable Interest Rate to the Indenture Trustee. In the event that the Primary Lender assigns the financing of all or any portion of the amount outstanding under the Credit Facility (whether or not evidenced by a Note) to the Alternate Lender or other assignee permitted by the terms of this Agreement, the interest rate on such amount shall be determined by the Facility Agent (and the Facility Agent shall notify the Indenture Trustee thereof and the Indenture Trustee shall confirm such interest rate based on information provided by the Facility Agent) pursuant to clause (i) of the definition of Applicable Interest Rate for the period prior to the effective date of such assignment and pursuant to clause (ii) of such definition for all periods after such date. (b) The Shipowner shall pay to the Facility Agent, on behalf of the Person(s) entitled to any Unpaid Amount, on demand, interest on such Unpaid Amount (to the extent permitted by applicable law) for each Post Maturity Period at an interest rate per annum equal to the sum (the "Post Maturity Interest Rate") of (1) two percent (2%), plus (2) the Applicable Interest Rate; provided, that if such Unpaid Amount consists of principal on the Floating Rate Note as to which guaranteed interest continues to accrue, the Post-Maturity Interest Rate on such Unpaid Amount shall be limited to 5

the incremental amount of additional interest required to be paid under this Section 4.02(b) and shall equal two percent (2.0%) per annum. In the absence of an Indenture Default, any interest which shall have accrued under this Section 4.02(b) in respect of an Unpaid Amount shall be due and payable and shall be paid by the Shipowner on demand on such dates as the Person to whom such Unpaid Amount is owed may specify by written notice to the Shipowner, or if there is an Indenture Default, any interest which shall have accrued under this Section 4.02(b) in respect of an Unpaid Amount shall be due and payable immediately and shall be paid by the Shipowner without demand and any payment by, or on behalf of, the Shipowner hereunder shall be governed by Section 7.02 and the provisions of the last paragraph of Section 9.02. As used herein, "Unpaid Amount" means all or any part of principal, accrued interest, fees or other amounts owing to the Agents or the Lenders under this Agreement or the Floating Rate Note which is not paid in full when and as due and payable, whether at Stated Maturity, by acceleration or otherwise, or any sum due and payable by the Shipowner to the Agents or the Lenders under any judgment of any court or arbitral tribunal in connection with this Agreement which is not paid on the date of such judgment. "LIBOR" shall mean, in relation to any Post Maturity Period (other than the first Post Maturity Period contemplated by clause (iii) of Section 4.02(b)), an interest rate per annum equal to (i) the rate of interest per annum (rounded upward, if necessary, to the nearest 1/16 of 1%) last quoted by the principal London office of CITIBANK, N.A., prior to the close of business at such London office on the Quotation Date for the offering to leading banks in the London interbank market of U.S. Dollar deposits on an overnight basis and in an amount comparable to the Unpaid Amount to which LIBOR is to apply divided by (ii) one hundred percent (100%) minus the Eurodollar Reserve Percentage. "Accelerated Repayment" shall mean any part of the principal of the Floating Rate Note that became due and payable on a day other than its Payment Date. "Post Maturity Period" shall mean with respect to the period from the date an Unpaid Amount was due until such amount shall have been paid in full, each successive period, the first of which shall start on the date such Unpaid Amount was due (or the date of any such judgment or arbitral award, if earlier) and each other of which shall start on the last day of the preceding such period, and the duration of each of which shall be one day, or if LIBOR applies, then from and including the Quotation Date for such Post Maturity Period to but excluding the next Quotation Date or such other duration selected by the Person to whom such Unpaid Amount is due; provided, however, that in the case of any Accelerated Repayment, the first such Post Maturity Period applicable thereto shall be of a duration equal to the unexpired portion of its then applicable Interest Period. "Quotation Date" in relation to any Post Maturity Period means the day on which quotations would ordinarily be given by CITIBANK, N.A. in the London interbank market for dollar deposits for delivery on the first day of that period; provided, however, that if, for any such Post Maturity Period, quotations would ordinarily be given on more than one date, the Quotation Date for that period shall be the last of those dates. 6

4.03 Prepayment. (a) The Shipowner may from time to time prepay on any Interest Payment Date all or any part of the Outstanding Principal evidenced by the Floating Rate Note, provided that: (i) any partial prepayment shall be in a minimum principal amount of $10,000,000, unless otherwise required by the Indenture; (ii) the Shipowner shall have given the Facility Agent and the Indenture Trustee prior written notice of such prepayment (which shall be not less than 40 nor more than 60 days); (iii) the Shipowner shall have paid in full all amounts due under this Agreement as of the date of such prepayment, including, without limitation, interest which has accrued to the date of prepayment on the amount prepaid and all other amounts payable hereunder relating to such prepayment; (iv) any amount prepaid hereunder (other than the Outstanding Principal amount thereof prepaid through the issuance of Fixed Rate Bonds, the Outstanding Principal amount of which is subtracted from the Credit Facility pursuant to the last sentence of Section 2.01) shall not be considered part of the Available Amount; and (v) subject to Section 4.03(c), if the Lender is the Primary Lender, the Shipowner shall pay to the Facility Agent, for the benefit of the Primary Lender an amount equal to (x) the amount of yield that the Primary Lender is required to pay to holders of its Commercial Paper during the Liquidation Period (as defined below) on an amount of Commercial Paper having an aggregate issue price equal to the amount of the Shipowner's prepayment less (y) the amount of the estimated investment earnings, as reasonably determined by the Facility Agent, on the prepayment amount during the Liquidation Period. The "Liquidation Period" means the period from the date on which a prepayment is made to the earliest date on which the Primary Lender's total amount of Commercial Paper related to the funding of the Disbursements can be reduced (without prepayment thereof) by an amount equal to the amount of the Shipowner's prepayment. Prepayments shall be applied to the installments of principal of the Credit Facility in the inverse order of their maturity, and, in cases where more than one Note is outstanding, pro rata to each Note. (b) Upon delivery to the Shipowner and the Secretary of the instrument satisfying and discharging the Indenture contemplated by Section 12.01 of the Exhibit 1 to the Indenture, all of the Shipowner's indebtedness, liabilities and obligations under this Agreement and the Fee Letter shall become immediately due and payable without demand upon, or notice to, the Shipowner. (c) Notwithstanding any other provision to the contrary herein, the Shipowner or the Secretary (after the Secretary's assumption of the Floating Rate Note pursuant to Section 6.09 of Exhibit 1 to the Indenture) may from time to time prepay all or any part of the principal amount of the Floating Rate Note without any prepayment penalty or premium in accordance with Article III of Exhibit 1 to the Indenture. (d) Notwithstanding any other provision to the contrary herein, the Shipowner shall have the right to prepay any portion of the Floating Rate Note and redeem the Floating Rate Note by issuing one or more Fixed Rate 7

Bonds and using the proceeds thereof to prepay the Floating Rate Note so long as it first obtains the Secretary's consent to the interest rate applicable to the Fixed Rate Bond and, except for the final disbursement, such redemption equals or exceeds $50,000,000 principal; and the Shipowner shall have paid any amount payable under Section 4.04(a)(iv) or any other provision hereof in connection therewith. 4.04 Recapture. (a) Upon the written request of the Facility Agent, the Shipowner shall pay to the Facility Agent for the benefit of the applicable Lender, such amounts as shall be sufficient (in the reasonable judgment of such Lender) to compensate such Lender for any loss, expense or liability (including, without limitation, any loss, expense or liability incurred by reason of the liquidation or redeployment of deposits from third parties or in connection with obtaining funds to make or maintain any Disbursement) which such Lender reasonably determines is attributable to: (i) any failure by the Shipowner to make scheduled payments on a Payment Date or any payment due in connection with any Redemption; or (ii) any failure by the Shipowner to borrow any advance for which a Certificate Authorizing Disbursement has been issued; or (iii) any revocation of a notice of prepayment given pursuant to Section 4.03(a); or (iv) subject to the provisions of Section 4.03(c), any prepayment of the Floating Rate Note (including, without limitation, due to the issuance of any fixed rate bonds) other than on an Interest Payment Date after giving five (5) Business Days' prior written notice to such Lender, the Facility Agent, and the Indenture Trustee. (b) Without prejudice to any other provision hereof (and at the Shipowner's expense), such Lender shall use such reasonable efforts as it shall determine in its sole discretion to minimize any loss, expense or liability to the extent possible; provided that no Lender shall be obligated to take any actions under this Section 4.04 if such Lender has determined, that such actions would cause it to incur any material costs or expenses or would otherwise be disadvantageous to it in any material respect. (c) With respect to the Shipowner's obligations under Section 4.04(a)(iv), if the Shipowner shall at any time notify the Facility Agent and the applicable Lender of its intention to pursue any such prepayment, the Facility Agent and the applicable Lender shall reasonably cooperate with the Shipowner in assessing and quantifying any loss, expense or liability the Lender may incur pursuant to Section 4.04(a)(iv), so that the Shipowner may make an informed decision as to the cost to it of any such prepayment. 4.05 Evidence of Debt. The Shipowner agrees that to evidence further its obligation to repay all amounts disbursed under the Credit Facility, with interest accrued thereon, it shall issue and deliver to the 8

Facility Agent, in accordance with the written instructions of the Facility Agent, the Floating Rate Note. The Floating Rate Note shall (i) be in the form of Exhibit 2 to the Indenture; (ii) bear the Secretary's Guarantee, and (iii) be valid and enforceable as to its principal amount at any time only to the extent of the aggregate amounts then disbursed and outstanding thereunder, and, as to interest, only to the extent of the interest accrued thereon at the rate guaranteed by the Secretary, with any interest in excess thereof being evidenced by this Agreement. 4.06 Limit of United States Guarantee.

(b) The Shipowner further agrees: (i) that, if the Shipowner is prevented by operation of law from paying any such Taxes or Other Taxes, or if any such Taxes or Other Taxes are required to be deducted or withheld, then the fees or expenses required to be paid under this Agreement shall, on an after-tax basis, be increased by the amount necessary to yield to the Lenders fees or expenses in the amounts provided for in this Agreement after the provision for the payment of all such Taxes and Other Taxes; (ii) that the Shipowner shall, at the request of any Lender or any Agent, execute and deliver to such Lender or Agent, as the case may be, such further instruments as may be necessary or desirable to effect the payment of the increased amounts as provided for in subsection (i) above; provided, however, that the Shipowner may not amend the Floating Rate Note without the prior written consent of the Secretary; (iii) that the Shipowner shall hold the Lenders and the Agents harmless from and against the full amount of Taxes and Other Taxes (including, without limitation, any Taxes or Other Taxes imposed by any jurisdiction on amounts payable under this Section 6.02) and any and all liabilities (including, without limitation, penalties, interest and expenses) arising from, or with respect to, any Taxes or Other Taxes (whether or not properly or legally asserted) and whether paid, or payable, by the Shipowner, the Lenders, or any other Person; (iv) that, at the request of any Lender or any Agent, the Shipowner shall provide such Lender or Agent within the later of thirty (30) calendar days after such request or thirty (30) calendar days after the payment of such Taxes or Other Taxes, a copy evidencing the payment of any Taxes or Other Taxes by the Shipowner; and (v) that each payment under this Section 6.02 shall be made within thirty (30) days from the date the Facility Agent on behalf of the applicable Lender makes written demand therefor. Each demand for payment by such Lender under Section 6.02(b)(v) for amounts paid or incurred by the Lenders or itself shall be accompanied by a certificate (with accompanying documentation supporting the demand) showing in reasonable detail the basis for the calculation of the amounts demanded, which certificate, in the absence of manifest error, shall be conclusive and binding for all purposes. (c) Notwithstanding anything to the contrary contained herein, the agreements in this Section 6.02 shall survive the termination of this Agreement and the payment of the Floating Rate Note and all other amounts due hereunder. 6.03 Expenses.

The Shipowner shall also pay all of the costs and expenses (including, without limitation, the fees and expenses of counsel) incurred by or charged to the Agents or the Lenders in connection with the amendment or enforcement of this Agreement, the Floating Rate Note or the Indenture or the protection or preservation of any right or claim of the Agents or the Lenders arising out of this Agreement, the Floating Rate Note or the Indenture. 6.04 Additional or Increased Costs. (a) If, due to either (i) the introduction of or any change in or in the interpretation of any law or regulation, or (ii) the compliance with any guideline or request from any central bank or other governmental authority (whether or not having the force of law), there shall be any increase in the cost to any Lender of agreeing to make or making, funding or maintaining the Disbursements or the Credit Facility, then the Shipowner shall from time to time, upon demand by such Lender, pay to such Lender additional amounts sufficient to compensate such Lender for such increased cost. (b) If any Lender determines that compliance with any law or regulation or any guideline or request from any central bank or other governmental authority (whether or not having the force of law) affects or would affect the amount of capital required to be maintained by such Lender or any corporation controlling such Lender and that the amount of such capital is increased by or based upon the existence of such Lender's commitment to lend hereunder and other commitments of this type, then, upon demand by such Lender, the Shipowner shall immediately pay to the Facility Agent (for the benefit of such Lender), from time to time as specified by the Facility Agent (on behalf of such Lender), additional amounts sufficient to compensate such Lender or such corporation in the light of such circumstances, to the extent that such Lender reasonably determines such increase in capital to be allocable to the existence of its commitment to lend hereunder. (c) Each Lender shall take such reasonable steps as it shall determine to minimize amounts demanded under this Section 6.04; provided that no Lender shall be obligated to take any actions under this Section 6.04 if such Lender has determined, that such actions would cause it to incur any material costs or expenses or would otherwise be disadvantageous to it in any material respect. In the event that a Lender transfers the booking office of the Credit Facility or the Floating Rate Note to minimize amounts demanded under this Section 6.04, any costs and expenses incurred in such transfer shall be paid by the Shipowner on demand by such Lender, provided, however, that any requirements imposed by this Section 6.04 on the Shipowner shall be no more burdensome than those imposed by the Lender on its highest rated and most favored customers who are subject to similar requirements. 13

(d) Each demand for payment by the Facility Agent (on behalf of any Lender) under this Section 6.04 shall be accompanied by a certificate showing in reasonable detail the basis for the calculation of the amounts demanded, which certificate, in the absence of manifest error, shall be conclusive and binding for all purposes. (e) The Facility Agent on behalf of each Lender shall notify the Shipowner of any event occurring after the date of this Agreement which entitles such Lender to compensation pursuant to this Section 6.04, as promptly as practicable, and in any event within ninety (90) days after it has knowledge of such event and has determined that a request for compensation hereunder shall be made. The Shipowner shall not be obligated to reimburse any Lender for any loss or cost incurred more than ninety (90) days prior to delivery of notice to the Shipowner by the Lender requesting compensation under this Section 6.04.

(c) Whenever a sum is required to be paid to the Facility Agent under this Agreement for the account of another Person, the Facility Agent shall not be obligated to make such sum available to such other Person unless and until the Facility Agent shall have established to its satisfaction that it has actually received payment of such sum. Notwithstanding the foregoing, unless it has received actual notice to the contrary, the Facility Agent may (but shall not be obligated to) assume on the date of any Disbursement or any other payment required to be made by any Lender hereunder that such Lender has made available to the Facility Agent such Disbursement or other payment and the Facility Agent may (but shall not be required to) make available to the Shipowner on such date a corresponding amount in reliance upon such assumption. Additionally, the Facility Agent may (but shall not be obligated to) assume on the date of any payment required to be made by the Shipowner hereunder that the Shipowner has made available to the Facility Agent such payment and the Facility Agent may (but shall not be required to) make available to the Lenders on such date a corresponding amount in reliance upon such assumption. If and to the extent that either (i) the Lender shall not in fact have made such Disbursement or other payment available to the Facility Agent and the Facility Agent has made available a corresponding amount to the Shipowner in reliance on the above-described assumptions or (ii) the Shipowner has not in fact made such payment and the Facility Agent has made available a corresponding amount to the Lender in reliance on the above-described assumptions, then, in either such case, such Lender agrees to repay to the Facility Agent forthwith on demand such corresponding amount together with an amount sufficient to indemnify the Facility Agent against any cost or loss it may have suffered or incurred by reason of its having paid out such sum prior to receipt thereof. 7.02 Application of Payments. In the absence of an Indenture Default, the Lenders shall each apply payments received by them under this Agreement and the Floating Rate Note (whether at Stated Maturity, by reason of acceleration, prepayment or otherwise), in the following order of priority: (i) interest due pursuant to Section 4.02(a); (ii) installments of principal due; (iii) interest due pursuant to Section 4.02(b) other than the amount described in clause (i) above; (iv) all amounts due under the Fee Letter; and (v) all other amounts due under this Agreement and not otherwise provided for in this Section 7.02. Upon the occurrence of an Indenture Default, the Lenders shall each hold any payments they receive after an Indenture Default from, or on behalf of, the Shipowner under this Agreement, the Fee Letter and any related agreement (excluding the Floating Rate Note) and shall promptly deliver such payments to the Secretary if the Secretary has been required to honor a Guarantee as a result of said Indenture Default. All such amounts received during an Indenture Default and delivered to the Secretary in accordance with 15

the preceding sentence shall be applied first to pay, satisfy and discharge all amounts owed by the Shipowner to the Secretary under the Secretary's Note and the Mortgage and then to pay, satisfy and discharge any and all amounts owed to the Lenders or the Agents.

Except as fully reflected in the Shipowner Financial Statements, there are no liabilities or obligations with respect to the Shipowner of any nature whatsoever (whether absolute, accrued, contingent or otherwise and whether or not due) for the period to which the Shipowner Financial Statements relate that, either individually or in the aggregate, would be material to the Shipowner. Since the date of the most recent Shipowner 17

Financial Statements, there has been no material adverse change in the financial condition, business prospects or operations of the Shipowner. "Shipowner Financial Statements" shall mean the financial statements of the Shipowner furnished to the Facility Agent prior to the date of this Agreement. (i) No Taxes. There is no Tax imposed on or in connection with: (i) the execution, delivery or performance of this Agreement, the Indenture or the Floating Rate Note; (ii) the enforcement of this Agreement, the Indenture or the Floating Rate Note; or (iii) on any payment to be made to any Lender under this Agreement or the Floating Rate Note. (j) Laws. None of the Indenture, the Floating Rate Note, the transactions contemplated thereunder nor any Person party to the Indenture or the Floating Rate Note is required to qualify under the Trust Indenture Act or register or qualify under any federal securities law. Neither this Agreement, nor the transactions contemplated hereunder, to the extent the same relate to the Shipowner's obligation and duties hereunder, is required to qualify under the Trust Indenture Act or register or qualify under any federal securities law. (k) Defaults. No Event of Default has occurred and is continuing and no event or circumstance has occurred and is continuing which with the passage of time, the giving of notice or both would constitute an Event of Default. 8.02 Agreements of the Shipowner. The Shipowner agrees that until all amounts owing under this Agreement and the Floating Rate Note have been paid in full, the Shipowner will, unless the Agents and the Lenders shall have consented in writing: (a) Notice of Defaults. Promptly, but in no event later than ten (10) days after the occurrence of an Indenture Default or an Event of Default of which the Shipowner has knowledge, notify the Facility Agent and the Indenture Trustee of any report required by the Shipowner Documents (or any other document entered into by the Shipowner in connection therewith), and send a copy thereof to the Facility Agent, in each case by facsimile or hand delivery. (b) Financial Reports. Beginning with the fiscal year in which this Agreement is executed and continuing until all amounts owing under this Agreement and the Floating Rate Note have been paid in full, the Shipowner shall furnish to the Facility Agent (and the Facility Agent, upon receipt thereof, shall furnish to each Lender and the Administrative Agent) a copy of all financial reports furnished to the Secretary pursuant to the Title XI Reserve Fund and Financial Agreement. (c) Other Acts. From time to time, do and perform any and all acts and execute any and all documents as may be necessary or as reasonably requested by the Facility Agent or the Indenture Trustee in order to effect the purposes of this Agreement and to protect the interests of the 18

Lenders in the Floating Rate Note and the interests of the Lenders in the Guarantees. (d) Use of Proceeds. Use proceeds from each Disbursement solely to finance: (i) the manufacture, construction, fabrication, financing and purchase of the Vessel; (ii) Construction Period Interest; and (iii) the Guarantee Fees. Use the proceeds from the issuance of any Fixed Rate Bonds to repay amounts owed under the Floating Rate Note or to finance: (i) the manufacture, construction, fabrication, financing and purchase of the Vessel; (ii) Construction Period Interest; and (iii) the Guarantee Fees. (e) Successors. Require that any successor to all or substantially all of its business as a result of any merger or consolidation with any other entity, dissolution or termination of legal existence, sale, lease, transfer or other disposal of any substantial part of its properties or any of its properties essential to the conduct of its business or operations, as now or hereafter conducted, any change in control, any agreement to do any of, or any combination of, the foregoing, to assume all of the Shipowner's indebtedness, liabilities and obligations under this Agreement, the Indenture and the Floating Rate Note. SECTION 9. CANCELLATION, SUSPENSION AND EVENTS OF DEFAULT 9.01 Cancellation. The Shipowner may cancel at any time all or any part of the Available Amount of the Credit Facility, provided that (i) thirty (30) days' prior irrevocable written notice is given to the Agents, the Indenture Trustee, and the Secretary and (ii) the Shipowner shall have paid to the Lenders any commitment fees accrued and unpaid under Section 6.01 and all other amounts due and payable under this Agreement and the Floating Rate Note as of the proposed date of cancellation. In the absence of an Indenture Default, the Lenders may not for any reason cancel at any time any part of the Available Amount of the Credit Facility, and in the event of an Indenture Default, the Lenders shall be governed by the provisions of Section 9.02 hereof with respect to the Available Amount. 9.02 Events of Default. Upon the occurrence of any of the following events or conditions (each, an "Event of Default"): (a) any failure by the Shipowner to pay when and as due any amount owing under this Agreement, but which is not guaranteed by the Secretary; or (b) any failure by the Shipowner to comply with its obligations under Section 8.02(a) or 8.02(d); or any failure by the Shipowner to perform or comply with any of its agreements set forth in this Agreement (exclusive of any events specified as an Event of Default in any other subsection of this Section 9.02 , which failure, if capable of being cured, remains uncured for a period of thirty (30) days after written notice thereof has been given to the Shipowner by the Facility Agent; or 19

(c) the Shipowner shall be unable to pay its debts when and as they fall due or shall admit in writing its inability to pay its debts as they fall due or shall become insolvent; or the Shipowner shall apply for or consent to the appointment of any liquidator, receiver, trustee or administrator for all or a substantial part of its business, properties, assets or revenues; or a liquidator, receiver, trustee or administrator shall be appointed for the Shipowner and such appointment shall continue undismissed, undischarged or unstayed for a period of thirty (30) days, or the Shipowner shall institute (by petition, application, answer, consent or otherwise) any bankruptcy, arrangement, readjustment of debt, dissolution, liquidation or similar executory or judicial proceeding; or a bankruptcy, arrangement, readjustment of debt, dissolution, liquidation or similar executory or judicial proceeding shall be instituted against the Shipowner and shall remain undismissed, undischarged or unstayed for a period of thirty (30) days; or (d) an Indenture Default has occurred; then, and in any such event, and at any time thereafter, if such event is continuing, and if there is no Indenture Default (or if there is an Indenture Default, only after the Secretary has received all payments due under the Secretary's Note and the Mortgage), any Agent or any Lender (by written notice to the Shipowner), shall have the right to institute any judicial or other proceedings under this Agreement to recover all amounts owing under this Agreement. The Lenders agree that so long as an Indenture Default exists, all amounts received during such period from, or on behalf of, the Shipowner shall be applied in the manner set forth in Section 7.02. Notwithstanding an Event of Default, the Lenders may not terminate the Available Amount of the Credit Facility without the Secretary's consent; provided, however, that the Shipowner's use of the Available Amount of the Credit Facility shall remain subject to the requirements of Sections 2.02, 3.01, and 5.02. Except as expressly provided above in this Section 9.02, presentment, demand, protest and all other notices of any kind are hereby expressly waived. Notwithstanding any other provision of this Agreement, if Section 9.02(c) is applicable, the Lender may file appropriate claims in connection therewith, but shall apply any funds collected as a consequence of said filings in accordance with the provisions of Section 7.02 of this Agreement. SECTION 10. GOVERNING LAW AND JURISDICTION 10.01 Governing Law. THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK. 10.02 Submission to Jurisdiction. Each of the Shipowner and the Lenders hereby irrevocably agrees that any legal suit, action or proceeding arising out of or relating to this Agreement, or any of the transactions contemplated hereby, may be instituted by the other parties hereto in the 20

Courts of the State of New York or the Federal Courts sitting in the Borough of Manhattan, City of New York, State of New York. Each of the Shipowner and the Lenders hereby irrevocably waives, to the fullest extent permitted by law, any objection which it may have now or hereafter to the laying of the venue or any objection based on forum non conveniens, or based on the grounds of jurisdiction with respect to any such legal suit, action or proceeding and irrevocably submits generally and unconditionally to the jurisdiction of any such court in any such suit, action or proceeding. Each of the Shipowner and the Lenders agrees that a judgment, after exhaustion of all available appeals, in any such action or proceeding shall be conclusive and binding upon it and may be enforced in any other jurisdiction by suit upon such judgment, a certified copy of which shall be conclusive evidence of the judgment. Each of the Shipowner and the Lenders waives personal service of any summons, complaint, or other process, which service may be made by such or any other means permitted by New York law. 10.03 Waiver of Security Requirements. To the extent the Shipowner may, in any action or proceeding arising out of or relating to this Agreement be entitled under applicable law to require or claim that the Agents or the Lenders post security for costs or take similar action, the Shipowner hereby irrevocably waives and agrees not to claim the benefit of such entitlement. 10.04 No Limitation. Nothing in this Section 10 shall affect the right of the Agents or any Lender to serve process in any manner permitted by law or to commence legal proceedings or otherwise proceed against the Shipowner in any jurisdiction; provided, however, that except as provided in Section 9.02, in the event of an Indenture Default, the Agents and the Lenders may not proceed against the Shipowner without the Secretary's consent unless the Secretary has received full payment under the Secretary's Note. SECTION 11. MISCELLANEOUS 11.01 Computations. Except for interest rates determined by the Indenture Trustee as provided in the Indenture, each determination of an interest rate by the Administrative Agent or the Facility Agent, or any other Person pursuant to any provision of this Agreement, the Fee Letter or the Floating Rate Note, in the absence of error, shall be conclusive and binding on the Shipowner. Each determination of a fee or other amounts (excluding interest rates) by the Facility Agent, any Lender, or any other Person pursuant to any provision of this Agreement, the Fee Letter or the Floating Rate Note, in the absence of manifest error, shall be conclusive and binding on the Shipowner. All computations of interest and fees hereunder and under the Floating Rate Note shall be made on the basis of a year of three hundred sixty (360) days and actual days elapsed. The Secretary and Indenture Trustee may request supporting documentation for the information provided by the Facility Agent or the Administrative Agent to the Indenture Trustee. 11.02 Notices.

Once the Shipowner has completely drawn down on the Credit Facility and the Available Amount is zero, each Lender may sell, assign, transfer, negotiate, or otherwise dispose of all or any part of its interest in all or any part of the Shipowner's indebtedness under this Agreement and the Floating Rate Note to any party (collectively, a "Disposition of Indebtedness"), and any such party shall enjoy all the rights and privileges of such Lender under this Agreement and the Floating Rate Note; provided, however, that each Disposition of Indebtedness to any Person other than another Lender or a domestic Affiliate of a Lender shall require the prior written consent of the Shipowner (which consent shall not be unreasonably withheld or delayed); provided, further, however, that each Lender may pledge or grant participation in all or any part of its interest in all or any part of the Shipowner's indebtedness under this Agreement and the Floating Rate Note to any party at any time so long as such Lender's commitment to lend the Available Amount under this Agreement is not affected thereby. The Shipowner shall, at the request of the Facility Agent, execute and deliver to the Facility Agent or to any party that the Facility Agent may designate, any such further instruments as may be necessary or desirable to give full force and effect to a Disposition of Indebtedness by the applicable Lender. 11.04 Disclaimer. Neither the Agents nor the Lenders shall be responsible in any way for the performance of the Construction Contract or any other Shipowner Document, and no claim against the Shipbuilder or any other Person with respect to the performance of the Construction Contract will affect the obligations of the Shipowner under this Agreement or the Floating Rate Note. 23

11.05 No Waiver; Remedies Cumulative. No failure or delay on the part of any Agent or any Lender in exercising any right, power or privilege under this Agreement, the Floating Rate Note or the Indenture and no course of dealing between or among the Shipowner and any Agent or any Lender shall operate as a waiver of the rights of the Shipowner and such Lenders against each other under this Agreement; nor shall any single or partial exercise of any right, power or privilege hereunder or under the Floating Rate Note or the Indenture preclude the Shipowner, the Agents, or the Lenders from exercising against each other any other right, power or privilege hereunder. The rights and remedies expressly provided herein are cumulative and not exclusive of any rights or remedies that the Agents or the Lenders would otherwise have. No notice to or demand on the Shipowner in any case shall entitle the Shipowner to any other or further notice or demand in similar or other circumstances or constitute a waiver of the rights of any Agent or any Lender under this Agreement to any other or further action in any circumstances without notice or demand. Notwithstanding any other provision to the contrary herein, no provision in this Agreement or any other related agreement preserves any rights in favor of the parties against the Secretary in the event that either party fails or delays to exercise any rights, powers, or privileges under this Agreement, the Floating Rate Note or the Indenture or engages in any particular course of dealing. 11.06 Currency. All payments of principal, interest, fees or other amounts due hereunder and under the Floating Rate Note shall be made in Dollars, regardless of any law, rule, regulation or statute, whether now or hereafter in existence or in effect in any jurisdiction, which affects or purports to affect such obligations. 11.07 Severability. To the extent permitted by applicable law, the illegality or unenforceability of any provision of this Agreement shall not in any way affect or impair the legality or enforceability of the remaining provisions of this Agreement. 11.08 Amendment or Waiver. This Agreement may not be changed, discharged or terminated without the written consent of the parties hereto, and no provision hereof may be waived without the written consent of the party to be bound thereby. There may be no change, discharge, termination or claim of waiver of the terms of this Agreement without the prior written consent of the Secretary, who is entitled to enforce his rights under this Agreement as an intended third party beneficiary to this Agreement. The parties hereto acknowledge, however, that nothing in this Agreement creates in either the Shipowner or the Lenders any right whatsoever against the Secretary. 11.09 Indemnification. Without limiting any other rights that any Agent or any Lender may have hereunder or under applicable law, the Shipowner hereby agrees to indemnify each of the Agents and the Lenders (each, an "Indemnified Party") from and against any and all damages, losses, claims, liabilities and related costs and expenses, including reasonable attorneys' fees and disbursements (all the foregoing being collectively referred to as "Indemnified Amounts") awarded against or incurred by such Indemnified 24

Party arising out of or as a result of this Agreement or the Floating Rate Note excluding, however, Indemnified Amounts to the extent resulting from gross negligence or willful misconduct on the part of such Indemnified Party. In the event of an Indenture Default, all amounts received by such Indemnified Party pursuant to such indemnification after an Indenture Default shall be held and paid in the manner required by Section 7.02. 11.10 Benefit of Agreement. This Agreement shall be binding upon and inure to the benefit of and be enforceable by the respective successors and assigns of the parties hereto; provided, however, that the Shipowner may not assign any of its rights or obligations hereunder without the prior written consent of the Lenders, and, to the extent set forth in paragraph 11.03 hereof, the Secretary. 11.11 Waiver of Jury Trial. Each of the Shipowner and the Lenders waives its respective rights to a trial by jury of any claim or cause of action based upon or arising out of or related to this Agreement, any assignment or the transactions contemplated hereby, in any action, proceeding or other litigation of any type brought by any party against the other parties, whether with respect to contract claims, tort claims, or otherwise. Each of the Shipowner and the Lenders agrees that any such claim or cause of action shall be tried by a court trial without a jury. Without limiting the foregoing, the parties further agree that their respective right to a trial by jury is waived by operation of this section as to any action, counterclaim or other proceeding which seeks, in whole or in part, to challenge the validity or enforceability of this Agreement, any assignment or any provision hereof or thereof. This waiver shall apply to any subsequent amendments, renewals, supplements or modifications to this Agreement or any assignment. 11.12 Execution in Counterparts. This Agreement may be executed in any number of counterparts, each of which when so executed shall be deemed to be an original and all of which when taken together shall constitute one and the same Agreement. Delivery of an executed counterpart of a signature page to this Agreement by facsimile shall be effective as delivery of a manually executed counterpart of this Agreement. 11.13 Shipowner Documents. Notwithstanding the provisions of this Agreement, in any conflict between this Agreement and the provisions of the Shipowner Documents, the Shipowner Documents shall govern the agreement between the parties hereto, but only with respect to the subject matter thereof. Notwithstanding the previous sentence, any provision in the Indenture (or any other agreement the Shipowner has entered into with any other Person) purporting to release the Shipowner of any indebtedness, liability or obligation shall not apply to any indebtedness, liability or obligation of the Shipowner hereunder and no termination of the Indenture (or any other agreement the Shipowner has entered into with any other Person) shall affect the continued effectiveness of this Agreement, which shall continue in full force and effect until the Credit Facility has been terminated and all indebtedness, liabilities and obligations of the Shipowner have been fully discharged and satisfied, the Floating Rate Note have been paid, satisfied and discharged in full, and there 25

has elapsed a year and a day from the last payment received from, or on behalf, of the Shipowner. However, this Section 11.13 shall have no affect on the relationships established and the agreements entered into by the parties to the Shipowner Documents (and such other agreements the Shipowner has entered into with any other Person), in each case to which the Lenders are not parties in their capacities as the Lenders hereunder. 11.14 Entire Agreement. This Agreement, the Fee Letter and the Floating Rate Note contain the entire agreement among the parties hereto regarding the Credit Facility. 11.15 No Proceedings. Each of the Shipowner, the Alternate Lender and the Agents hereby agrees that it will not institute against, or join any other Person in instituting against, the Primary Lender any bankruptcy, reorganization, arrangement, insolvency or liquidation proceeding, or any other proceeding under any federal or state bankruptcy or similar law, so long as any Commercial Paper issued by the Primary Lender shall be outstanding or there shall not have elapsed one year plus one day since the last day on which any such Commercial Paper shall have been outstanding. SECTION 12. ARRANGEMENTS AMONG THE AGENTS AND THE LENDERS 12.01 Appointment. Each Lender hereby appoints the Facility Agent to act as its agent in connection herewith and in connection with the Floating Rate Note and the Indenture and authorizes the Facility Agent to exercise such rights, powers and discretions as are specifically delegated to the Facility Agent by the terms hereof and thereof, together with all such rights, powers and discretions as are reasonably incidental thereto. Without limiting the foregoing, all notices to be delivered to, and approvals to be given by, a Lender under the disbursement procedures described in Section 3.01 hereof shall be delivered to and given by the Facility Agent on behalf of such Lender. 12.02 Rights of Facility Agent. The Lenders and the Facility Agent agree that the Facility Agent may: (i) assume that (a) any representation made by the Shipowner in connection herewith is true; (b) no event which is or may become an Event of Default has occurred; (c) the Shipowner is not in breach of or default under its obligations hereunder; (d) any right, power, authority or discretion vested herein upon the Lenders or any other person or group of persons has not been exercised; unless it has, in its capacity as Facility Agent, notice or actual knowledge to the contrary; (ii) engage and pay for the advice or services of any lawyers, accountants, surveyors or other experts whose advice or services may to it seem necessary, expedient or desirable and rely upon any advice so obtained; (iii) rely as to any matters of fact that might reasonably be expected to be within the knowledge of the Shipowner upon a certificate signed by or on behalf of the Shipowner; 26

(iv) rely upon any communication or document believed by it to be genuine; (v) refrain from exercising any right, power or discretion vested in it as facility agent hereunder unless and until instructed by a Lender as to whether or not such right, power or discretion is to be exercised and, if it is to be exercised, as to the manner in which it should be exercised; and (vi) refrain from acting in accordance with any instructions of any Lender to begin any legal action or proceeding arising out of or in connection with this Agreement until it shall have received such security as it may require (whether by way of payment in advance or otherwise) for all costs, claims, expenses (including legal fees) and liabilities which it will or may expend or incur in complying with such instructions. 12.03 Duties. The Facility Agent shall: (i) promptly inform each Lender of the contents of any notice or document received by it from the Shipowner hereunder; (ii) promptly notify each Lender of the occurrence of any Event of Default or any default by the Shipowner in the due performance of or compliance with its obligations under this Agreement of which the Facility Agent has notice from any other party hereto; (iii) save as otherwise provided herein, act as facility agent hereunder in accordance with any instructions given to it by any Lender, which instructions shall be binding on all of the Lenders; and (iv) if so instructed by any Lender, refrain from exercising any right, power or discretion vested in it as facility agent hereunder. 12.04 Limitation on Obligations of Facility Agent. Notwithstanding anything to the contrary expressed or implied herein, the Lenders and the Facility Agent agree that the Facility Agent shall not: (i) be bound to inquire as to: (a) whether or not any representation made by the Shipowner in connection herewith is true; (b) the occurrence or otherwise of any event which is or may become an Event of Default; 27

(c) the performance by the Shipowner of its obligations hereunder; or (d) any breach of or default by the Shipowner or under its obligations hereunder; (ii) be bound to account to any Lender for any sum or the profit element of any sum received by it for its own account; (iii) be bound to disclose to any other person any information relating to the Shipowner or any of its agencies if such disclosure would or might in its opinion constitute a breach of any law or regulation or be otherwise actionable at the suit of any person; or (iv) be under any obligations other than those for which express provision is made herein. 12.05 Indemnification by Lenders. The Alternate Lender shall, from time to time on demand by the Facility Agent, indemnify the Facility Agent, against any and all costs, claims, expenses (including legal fees) and liabilities (collectively, "Liabilities") together with any tax thereon which the Facility Agent may incur, otherwise than by reason of its own gross negligence or willful misconduct, in acting in its capacity as facility agent hereunder (including, without limitation, any Liabilities in anyway relating to or arising out of certifications made with respect to either (a) the due authorization, execution or delivery of a Floating Rate Note, or (b) laws and/or regulations of any Governmental Authority, in each case in connection with any request by the Facility Agent to the Indenture Trustee or the Secretary for the Secretary to endorse its guarantee on a Floating Rate Note or for the Indenture Trustee to authenticate a Floating Rate Note). 12.06 Limitation on Responsibility. The Facility Agent accepts no responsibility to the Lenders for the accuracy and/or completeness of any information supplied by the Shipowner in connection herewith or for the legality, validity, effectiveness, adequacy or enforceability of this Agreement, and the Facility Agent shall be under no liability to the Lenders as a result of taking or omitting to take any action in relation to this Agreement, save in the case of its own negligence or willful misconduct. 12.07 No Claims on Employees of Facility Agent. Each Lender agrees that it will not assert or seek to assert against any director, officer or employee of the Facility Agent any claim that it might have against it in respect of the matters referred to in Clause 12.06. 12.08 Banking Business. The Lenders agree that the Facility Agent may accept deposits from, lend money to and generally engage in any kind of banking or other business with the Shipowner. 28

12.09 Resignation or Termination of Facility Agent. (i) The Facility Agent may (after consultation with the Shipowner and the Lenders) resign its appointment hereunder at any time without assigning any reason therefor by giving not less than thirty (30) days' prior written notice to that effect to each of the other parties hereto; provided, that no such resignation shall be effective until a successor for the Facility Agent is appointed in accordance with the succeeding provisions of this Section 12; (ii) The Lenders and the Shipowner may jointly seek the termination of the appointment of the Facility Agent hereunder at any time by giving not less than thirty (30) days prior written notice to that effect to the Facility Agent; provided that no such termination shall be effective until a successor for the Facility Agent is appointed in accordance with the succeeding provisions of this Section 12; provided, further that any such notice of termination must be signed by all of the Lenders and the Shipowner; and (iii) For the avoidance of doubt, the parties hereto agree that the provisions of this Section 12.09 shall at no time apply to or restrict the ability of the Administrative Agent to resign its position of Administrative Agent. 12.10 Successor to Facility Agent. If the Facility Agent gives notice of its resignation pursuant to Section 12.09(i) or receives notice of termination pursuant to Section 12.09(ii), then any reputable and experienced bank or other financial institution may be appointed as a successor to the Facility Agent by the Lenders with the consent of the Secretary and Shipowner (which consent of the Shipowner shall not be unreasonably withheld or delayed) during the period of such notice but, if no such successor is so appointed, the Facility Agent may appoint such a successor itself with the consent of the Secretary and Shipowner (which consent of the Shipowner shall not be unreasonably withheld or delayed). 12.11 Discharge of Obligations. If a successor to the Facility Agent is appointed under the provisions of Section 12.10, then (i) the retiring Facility Agent shall be discharged from any further obligation hereunder but shall remain entitled to the benefits of the provisions of this Section 12 and (ii) its successor and each of the other parties hereto shall have the same rights and obligations amongst themselves as they would have had if such successor had been a party hereto. 12.12 Responsibilities of Lenders. It is understood and agreed by each Lender that it is, and will continue to be, solely responsible for making its own independent appraisal of and investigations into the financial condition, creditworthiness, condition, affairs, status and nature of the Shipowner, the Secretary and the United States of America and, accordingly, each Lender warrants to the Facility Agent that it has not relied and will not hereafter rely on the Facility Agent: (i) to check or inquire on its behalf into the adequacy, accuracy or completeness of any information provided by 29

the Shipowner in connection with this Agreement or the transaction herein contemplated (whether or not such information has been or is hereafter circulated to such Lender by the Facility Agent); or (ii) to assess or keep under review on its behalf the financial condition, creditworthiness, condition, affairs, status or nature of the Shipowner. 12.13 Agency Division. In acting as Facility Agent for the Lenders, the Facility Agent's agency division shall be treated as a separate entity from any other of its divisions or departments and, notwithstanding the foregoing provisions of this Section 12, in the event that the Facility Agent should act for the Shipowner in any capacity in relation to any other matter, any information given by the Shipowner to the Facility Agent in such other capacity may be treated as confidential by the Facility Agent. 12.14 Administrative Agent. Each party hereto (other than the Administrative Agent) acknowledges that the Administrative Agent is a party hereto only in its capacity as administrative agent of the Primary Lender and the Primary Lender's commercial paper holders. 12.15 Facility Agent Only Agent for the Lenders. The Facility Agent is not authorized to, nor shall it, act as the agent for the Secretary, the Indenture Trustee, the Shipowner or any of their successors in interest or assigns in any of the capacities provided for herein. 30

EXHIBIT 10.2 SUBSEA GROUP 2002 ANNUAL INCENTIVE COMPENSATION PROGRAM ================================================================================ 1. INTRODUCTION CDI Incentive Compensation Plans were originally designed in 1993 to align the interests of employees with those of Cal Dive shareholders to the maximum extent possible. Employees share in the superior performance of the company recognizing that the shareholders are entitled to a threshold level of performance in exchange for base salaries. The threshold level is based on the Annual Budget established by management and approved by the Board of Directors. Incentives based upon performance above that threshold level can result in total cash compensation to CDI employees well above competitive levels for the industry. For the subsea group there are two plans: one for onshore operational personnel - the Operations Plan; and one for executive management, accounting and administrative personnel - the Administrative Plan, The general conditions of both plans are: (i) ELIGIBILITY FOR PARTICIPATION Participants must be on the payroll no later than June 30, 2002. Participants who are not on the payroll as of January 1, 2002, will have their opportunity prorated by their months of service. Incentive compensation awards will be granted to those participants who have met the performance criteria set forth in this policy and who are on the payroll December 31, 2002, for incentive compensation under this plan. This plan is not to be construed in any way as a guarantee of employment or an employment contract. (ii) METHOD OF PAYMENT Any cash components of the two plans will be paid by March 15, 2003. (iii) CLARIFICATION/INTERPRETATION/MODFICATION OF THE PLANS The Compensation Committee of the Cal Dive Board of Directors shall have the right and the sole authority at any time and without restriction to clarify, interpret and/or modify plan. 400-0164 March 27, 2002

2. OPERATIONS PLAN The 2001 Operations Plan is designed to reward key Vice Presidents, Project Managers and Project Support personnel for the contribution made towards achieving the company's growth and profitability targets. Potential bonuses under this program are limited only by the success and cost effectiveness of COMBINED effort. As last year cash incentive compensation will be linked to exceeding a threshold above the budgeted expectation for earnings. Stock options will be awarded during the first quarter of 2002 to compensate participants for accepting this higher hurdle. * THRESHOLD PERFORMANCE: Cash incentive compensation is earned, when financial performance exceeds 110% of the subsea contribution to the budgeted earnings estimate. * BONUS POOL: The bonus pool of the Operations pool is in addition to a bonus pool for the Administrative Group. * SG&A: Operations pool is increased or decreased by variances to budgeted SG&A expenses. This year SG&A cost targets are set for each Vice President. * DISCRETIONARY COMPONENT: 40% of the allocated incentive award is based upon discretion of Senior management and achievement of individual goals. * SUPPORT STAFF: Each Group may use a portion of their bonus pool or incentives not awarded in the discretionary component to make bonus payments to support staff. * STOCKOPTIONS: As in 2001, stock options plus cash will be used in payment of potential bonuses earned. The proposed plan is in keeping with the authorized 10% level allocated for employee stock options. Each eligible participant's incentive compensation OPPORTUNITY will be based on the following: 1. Attaining 2001 "Subsea Division" (exclusive of Canyon and ERT) gross profit of $45,000,000 will result in an OPPORTUNITY equal to 10% of the eligible participants base salary. 2. Variances to budgeted Subsea SG&A (as defined) will be added to (or deducted from) gross profit in determining 1 above. 3. A bonus pool will be established equal to 20% of all dollars of gross profit (as adjusted) in excess of $45,000,000. 400-0164 March 27, 2002

The bonus pool will be divided into four weighted tiers and will be available as an incentive compensation OPPORTUNITY for each eligible participant within a tier in direct proportion to the ratio of the eligible participant base salaries. TIER GROUP DESIGNATIONS: Group 1 - Vice Presidents Group 2 - Personnel in direct control of: o Significant direct authorization control responsibility of costs, or o Significant direct negotiation or contracting responsibility of costs or receivables. Group 3 - Personnel in key roles of execution, operations with impact to the bottom line. Group 4 - Personnel in supporting roles with impact on cost control. Each participant's OPPORTUNITY will be awarded based as follows: 1. 60% of the total opportunity will be awarded based on achieving the financial goals. 2. From 0 to 40% of the total opportunity will be awarded based on an evaluation by Executive Management regarding the individual's efforts, contribution and success in achieving specific goals established by the President and appropriate Vice President. Any portion of the opportunity that is not awarded may be reallocated to other plan participants. 3. In 2002 the discretionary part of the bonus will be directly linked to: Safety Management performance, teamwork efforts, cost management effectiveness and other specific individual/departmental goals. In particular 10% of the bonus opportunity will be based on beating the safety incident rate target of 1.5. 4. Also for 2002, 20% of the bonus opportunity for Vice Presidents will be linked to achieving the attached SG&A targets. 5. Discretionary bonuses may be paid to support staff from the bonus pool or incentives not awarded in the discretionary component. Stock options will also be used as a component of the incentive plan to compensate subsea operations personnel for accepting a higher than budgeted gross profit target. 400-0164 March 27, 2002

STOCK OPTION POOL: o 300,000 options shall be set aside for use in the incentive compensation plan. o The options will be issued in lieu of a cash bonus for achieving budgeted gross profit, as in previous plans. o Distribution of options: Stock options will be awarded to individuals depending on their bonus grouping. o All options awards to vest over three (3) years with a total life of ten (10) years. o Exercise price to be the market price on the date they are granted during the first quarter. The gross profit goal reflects management's assessment of revenue producing assets on hand or expected to be acquired at the time the Business Plan is prepared. The goal shall NOT be adjusted should any of these assets be sold or not acquired subsequent to the Business Plan being approved by the Board of Directors. However, if the company subsequently purchases or otherwise acquires new assets with the expectation of increasing the gross profit of the Subsea Division, the gross profit levels will be adjusted to allow for a reasonable return to the company. This adjustment will be based on the economics presented to the Board of Directors as justification for the new equipment or service (the approved AFE) and will be prorated for months in service. In addition, the gross profit goal established in the approved budget will not be adjusted for changes in accounting policy made during a fiscal year. 400-0164 March 27, 2002

2002 SG&A COST TARGETS 40% of bonus awards are discretionary. Half of this, or 20%, will be based on an individual manager's ability to manage SG&A costs for their respective group to a target % of relevant revenues in accordance with the following: (See budget and management guidelines (SG&A) for more detail). - -------------------------------------------------------------------------------- GROUP MANAGER TARGET % OF REVENUE - -------------------------------------------------------------------------------- Scott Naughton 1.96% - -------------------------------------------------------------------------------- Steve Brazda 8.50% - -------------------------------------------------------------------------------- Mike Ambrose 2.20% - -------------------------------------------------------------------------------- Wayne Bywater 1.46% - -------------------------------------------------------------------------------- Ian Collie 0.60% - -------------------------------------------------------------------------------- Mark McWatters 4.20% - -------------------------------------------------------------------------------- Wade Pursell 2.00% - -------------------------------------------------------------------------------- Jim Connor 2.00% - -------------------------------------------------------------------------------- 400-0164 March 27, 2002

A bonus pool will be established based upon (a) 4% of the first $2 million of consolidated net income in excess of targeted net income, plus (b) 6% of any consolidated net income in excess of targeted net income plus $2 million. The bonus pool will be available for each eligible participant in direct proportion to the ratio of eligible participant base salaries. Each participant's opportunity will be awarded based as follows: 1. 70% of the total opportunity will be awarded based upon achieving financial goals. 2. From 0 to 30% of the total opportunity will be awarded based upon a subjective evaluation by the Compensation Committee and Executive management regarding the individual's efforts, contribution and success in achieving specific goals established by the Group Vice President and Board of Directors.

(f) Gross-Up Payments - Certain Additional Payments by the Company. (i) Anything in this Agreement to the contrary notwithstanding, in the event it shall be determined that any payment or distribution by the Company or any of its affiliates (as that term is defined in the regulations promulgated under the Securities Exchange Act of 1934, as amended) under this Agreement to or for the benefit of Employee (any such payments or distributions being individually referred to herein as a "PAYMENT," and any two or more of such payments or distributions being referred to herein as "PAYMENTS"), would be subject to the excise tax imposed by Section 4999 of the Code (such excise tax, together with any interest thereon, any penalties, additions to tax, or additional amounts with respect to such excise tax, and any interest in respect of such penalties, additions to tax or additional amounts, being collectively referred herein to as the "EXCISE TAX"), then Employee shall be entitled to receive an additional payment or payments (individually referred to herein as a "GROSS-UP PAYMENT" and any two or more of such additional payments being referred to herein as "GROSS-UP Payments") in an amount such that after payment by Employee of all taxes (as defined in Section 7(f)(xi) imposed upon the Gross-Up Payment, Employee retains an amount of such Gross-Up Payment equal to the Excise Tax imposed upon the Payments. (ii) Subject to the provisions of Section 7(f)(iii) through 7(f)(ix), any determination (individually, a "DETERMINATION") required to be made under this Section 7(f)(ii), including whether a Gross-Up Payment is required and the amount of such Gross-Up Payment, shall initially be made, at the Company's expense, by nationally recognized tax counsel mutually acceptable to the Company and Employee ("TAX COUNSEL"). Tax Counsel shall provide detailed supporting legal authorities, calculations, and documentation both to the Company and Employee within 15 business days of the termination of Employee's employment, if applicable, or such other time or times as is reasonably requested by the Company or Employee. If Tax Counsel makes the initial Determination that no Excise Tax is payable by Employee with respect to a Payment or Payments, it shall furnish Employee with an opinion reasonably acceptable to Employee that no Excise Tax will be imposed with respect to any such Payment or Payments. Employee shall have the right to dispute any Determination (a "DISPUTE") within 15 business days after delivery of Tax Counsel's opinion with respect to such Determination. The Gross-Up Payment, if any, as determined pursuant to such Determination shall, at the Company's expense, be paid by the Company to Employee within five business days of Employee's receipt of such Determination. The existence of a Dispute shall not in any way affect Employee's right to receive the Gross-Up Payment in accordance with such Determination. If there is no Dispute, such Determination shall be binding, final and conclusive upon the Company and Employee, subject in all respects, however, to the provisions of Section 7(f)(iii) through 7(f)(ix) below. As a result of the uncertainty in the application of Sections 4999 and 280G of the Code, it is possible that Gross-Up Payments (or portions thereof) which will -6-

not have been made by the Company should have been made ("UNDERPAYMENT"), and if upon any reasonable written request from Employee or the Company to Tax Counsel, or upon Tax Counsel's own initiative, Tax Counsel, at the Company's expense, thereafter determines that Employee is required to make a payment of any Excise Tax or any additional Excise Tax, as the case may be, Tax Counsel shall, at the Company's expense, determine the amount of the Underpayment that has occurred and any such Underpayment shall be promptly paid by the Company to Employee.
