PART I ITEM 1. BUSINESS. OVERVIEW We are an energy services company specializing in subsea construction and well operations as well as providing oil and gas companies with alternatives to traditional approaches of equity sharing in offshore properties. We operate primarily in the Gulf of Mexico, or Gulf, and recently in the North Sea with services that cover the lifecycle of an offshore oil and gas field. We believe we have a longstanding reputation for innovation in our subsea construction techniques, equipment design and methods of partnering with customers. Our diversified fleet of 23 vessels and 21 remotely operated vehicles (or ROVs) and trencher systems perform services that support drilling, well completion, intervention, construction and decommissioning projects involving pipelines, production platforms, risers and subsea production systems. We also have acquired significant interests in oil and gas properties and related production facilities as part of our Production Partnering business. Our customers include major and independent oil and gas producers, pipeline transmission companies and offshore engineering and construction firms. We have positioned ourselves for work in water depths greater than 1,000 feet, referred to as the Deepwater, by continuing to grow our technically advanced fleet of dynamically positioned, or DP, vessels, ROVs and the number of highly experienced support professionals we employ. In early 2002, we purchased our new ROV subsidiary, Canyon Offshore, Inc., that offers survey, engineering, repair, maintenance and international cable burial services in the Gulf, North Sea and Southeast Asia. Later in mid-2002, our Well Ops (U.K.) Limited subsidiary purchased the North Sea well operations business unit of Technip-Coflexip ("Technip") including one large DP vessel, work contracts and personnel. This fleet of DP vessels serves as advanced work platforms for the subsea solutions that we provide with our alliance partners, a group of internationally recognized contractors and manufacturers. Most notably, the Q4000, our Deepwater semi-submersible multi-service vessel, or MSV, incorporates patented technologies that can improve Deepwater well completion, intervention and construction economics for our customers. Availability of the Q4000, and four other large vessels that we recently purchased or upgraded, the Eclipse, Mystic Viking, Intrepid and Seawell, enables us to offer a diverse fleet of DP subsea construction and intervention vessels (four of which are based in the Gulf). On the Outer Continental Shelf, or OCS, in water depths up to 1,000 feet, we perform traditional subsea services, including air and saturation diving and salvage work. Our shallow operations division, Aquatica, provides a full complement of services in the shallow water market from the shore to a depth of 300 feet. Aquatica's eight vessels are permanently dedicated to performing traditional diving services. In depths from 300 feet to 1,000 feet, these services are provided by our two four-point saturation diving vessels, with another five DP vessels capable of providing such services, on the OCS. We provide marine construction services in the OCS "spot market" where projects are generally turnkey in nature, short in duration (two to thirty days), and require the availability of multiple vessels due to frequent rescheduling. The technical and operational experience of our personnel and the scheduling flexibility offered by our large fleet enable us to manage turnkey projects and to meet our customers' requirements. We have also established a presence in the salvage market by offering customers a number of options to address their decommissioning obligations in a cost-efficient manner, particularly 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., or ERT, acquires and produces mature, non-core offshore property interests, offering customers a cost-effective alternative to the decommissioning process required by law. Market conditions in 2002 allowed ERT to add significantly to its property base through large property acquisitions from Williams Production RMT Company (a subsidiary of the Williams Companies), Amerada Hess Corporation, subsidiaries of Shell Exploration and Production Company, and a venture consisting of Murphy Exploration & Production Company ("Murphy") and Callon Petroleum Operating Company ("Callon"), adding over 70 BCFe to ERT's reserves. In the acquisition from the Murphy/Callon joint venture, ERT acquired and successfully developed a "Stranded 1

Field" property, i.e., one where the exploratory well had encountered proven reserves yet the reserves were of a marginal size to Murphy while Callon was constrained by capital expenditure requirements. We also expanded our Production Partnering strategy through participation in the ownership of the TLP production facility for the Marco Polo field, a Deepwater Gulf oil and gas exploration project operated by Anadarko Petroleum Corporation. We expect that owning this tension-leg platform, or TLP, in a 50/50 joint venture with El Paso Energy Partners, L.P. will generate income for us in the future and also provide us with additional construction work for Cal Dive and farm-in opportunities for ERT. ERT's reservoir engineering and geophysical expertise enabled us in 2000 to acquire a working interest in Gunnison, a Deepwater Gulf oil and natural gas exploration project, in partnership with the operator, Kerr-McGee Corporation. We anticipate that these investments will generate income for us in the future and will also help secure utilization for our subsea assets. At both Gunnison and Marco Polo, we participate in field development planning and have been contracted to perform subsea construction work. Cal Dive was incorporated in Minnesota in 1983 as a successor to California Divers, Inc. a company originally incorporated in 1964. We make available through our website, www.caldive.com, our Annual Report on Form 10-K, quarterly reports on Form 10-Q, current reports on Form 8-K, and amendments to those reports filed or furnished pursuant to Section 13(a) or 15(d) of the Exchange Act as soon as reasonably practicable after we electronically file such material with, or furnish it to, the SEC. Our overall corporate goal is to increase shareholder value by strengthening our market position to provide a return that leads our Peer Group. We have been able to achieve our return on capital objective by focusing on the following business strengths and strategies. OUR STRENGTHS Fleet of DP Vessels. Our fleet of DP vessels and ROVs is one of the largest permanently deployed in the Gulf, with one of the most diverse and technically advanced collections of subsea intervention and construction capabilities. The comprehensive services provided by our DP vessels are both complementary and overlapping, enabling us to provide customers the redundancy essential for most projects, especially in the Deepwater. Formation of New Well Operations Subsidiary as a "First In" Advantage. In 2002 we formed a new wholly owned subsidiary, Well Ops Inc., to provide offshore oil and gas operators with the experience, expertise and technology for cost-effective subsea well operations. Establishment of the Well Ops group followed the construction of the purpose-built Q4000 and the acquisition of the Subsea Well Operations Business Unit of Technip in Aberdeen, Scotland. The mission of the new companies is to provide the industry with a single, comprehensive source for addressing current well operations needs and to engineer for future needs. Experienced Personnel and Turnkey Contracting. A key element of our successful growth has been our ability to attract and retain experienced personnel who are among 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 position in the Gulf for saturation diving services make us the largest supplier of marine construction services on the OCS. We expect the ongoing depletion of existing reserves, coupled with growing demand for natural gas, to require increased exploitation and development of OCS reservoirs. Production Partnering. The strategy of ERT's oil and gas production business differentiates us from our competitors and helps to offset the cyclical nature of our marine construction operations. Each of ERT's oil and gas investments is designed to secure utilization of CDI construction vessels. Our long-term goal is that 40% of all of our construction utilization is provided by ERT's ownership of offshore fields and production facilities. 2

Decommissioning Operations. Over the last decade, we have established a presence in decommissioning offshore facilities, particularly in the removal of the smaller structures and caissons that make up approximately half of the structures in the Gulf. 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 Gulf of Mexico, where we have provided marine construction services since 1975. We expect oil and gas exploration and development activity in the Gulf, particularly in the Deepwater, to increase over the next several years. Capturing a Leading Presence in the Deepwater Market. We have recently expanded our fleet to service Deepwater projects by purchasing the Mystic Viking, a 242 foot DP vessel; the Eclipse, a large mono-hull vessel with significant deck load capacity; and the Seawell, a purpose built DP well operations vessel. In addition, in 2002 we took delivery of the Q4000 and the Intrepid. Our fleet now includes nine world-class DP vessels, seven of which are based in the Gulf of Mexico. In addition, through Canyon we now own and operate 21 ROV and trencher systems. Canyon represents an integration that is consistent with our strategy of controlling all aspects along the critical path of significant projects. In addition, we are presently building a "T750" Super Trencher as well as 3 Triton XLS ROV systems to fulfill requirements under a Master Service Agreement entered into with Technip. Developing Well Operations Niche. It is estimated that over 2,000 subsea trees will be installed in the years 2002 through 2006. Currently there are few cost-effective solutions for subsea well operations to troubleshoot or enhance production, shift zones or perform recompletions, as all such work today must generally be done from drilling rigs. Our three purpose-built vessels serve as work platforms for well operations services at costs significantly less than drilling rigs. In the Gulf of Mexico, the new, multi-service semi-submersible Q4000 and the Uncle John have set a series of "firsts" in increasingly deep water without the use of a rig. In the North Sea, the Seawell has provided intervention and abandonment services for more than 400 North Sea wells since her commissioning in 1987. Competitive advantages of the CDI vessels stem from their lower operating costs, ability to mobilize quickly and to maximize productive time by performing a broad range of tasks for intervention, construction, inspection, repair and maintenance. Acquiring Mature Oil and Gas Properties. Through ERT we have been acquiring mature or sunset properties since 1992, thereby providing customers a cost effective alternative to the decommissioning process. In the last ten years we have acquired interests in 89 leases and currently are the operator of 42 of 63 active offshore leases. ERT has been able to achieve a significant return on capital by efficiently developing acquired reserves, lowering lease operating expenses and adding new reserves through well work. Our customers consider ERT a preferred buyer as ERT is a bonded offshore operator and has access to Cal Dive's decommissioning assets. As the industry wide leader of acquiring mature properties, ERT has a significant flow of potential acquisitions. At December 31, 2002, ERT's total proven reserves were 157.5 BCFe, including 73.8 BCFe of initial proved reserves assigned to our ownership position in Gunnison. Expanding Ownership in Deepwater Developments. Cal Dive has a 20% working interest position in the Deepwater Gunnison field and owns 50% of the tension leg production platform being constructed with El Paso Energy Partners for the Marco Polo field. Ownership of the TLP provides a transmission type return which does not entail any reservoir or commodity price risk. The Company plans to seek additional opportunities to invest in such production facilities. Expanding the Stranded Field Model. Drilling activity in the Gulf since 1998 has consistently exceeded 70 exploratory wells per year with approximately 30% resulting in new discoveries. Because of the smaller size of the reservoirs today, there are many commercial discoveries in the Deepwater Gulf of Mexico that have yet to be brought into production. In addition, many of the wells deemed non-commercial or those in non-core areas are attractive to the Company. During 2002, the Company acquired and successfully developed its first proved undeveloped reserve ("PUD") prospect, East Cameron 374, a field acquired from Murphy Exploration and Callon. The Eclipse and Cal Diver I assisted in the successful development of this field. Depending upon 3

the water depth, development of these fields may require state of the art equipment such as the Q4000, a more specialized asset such as the Intrepid, for pipelay or a combination of Cal Dive contracting assets. The Company is considering a number of alternatives that would provide outside investor funding to expand this market niche. THE INDUSTRY 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 oil and gas 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 subsea construction assets in the face of foreign dependency and increasing U.S. and world demand; - advances in exploration, extraction and production technology that have enabled industry participants to more cost-effectively enter the Deepwater Gulf; and - increased demand for decommissioning services as the offshore oil and gas industry continues to mature. In response to the oil and gas industry's ongoing 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 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. Defined below are certain terms and ideas helpful to understanding the services we perform in support of offshore development: BCFe: When describing oil and gas, the term converts oil volumes to their energy equivalent in natural gas and combines them in billions of cubic feet equivalent. Deepwater: Water depths beyond 1,000 feet. 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. EHS: Environment, Health and Safety programs to protect the environment, safeguard employee health and eliminate injuries. E&P: Companies involved in oil and gas exploration and production activities. 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. 4

Minerals Management Service (MMS): The federal 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 depth. Peer Group: Defined in this Annual 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). Production Partnering: Alternative approach (i) to equity sharing in offshore properties through the purchase of mature fields and those fields where exploratory drilling encountered less than expected reserves and (ii) to ownership of production facilities. Proved Undeveloped Reserve (PUD): Proved undeveloped oil and gas reserves that are expected to be recovered from a new well on undrilled acreage, or from existing wells where a relatively major expenditure is required for recompletion. 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. 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 sea bed 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. Stranded Field: Smaller reservoir that standing alone may not justify the economics of a host production facility and/or infrastructure connections. 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. Tension Leg Platform (TLP): A floating Deepwater compliant structure designed for offshore hydrocarbon production. Trencher or Trencher System: A subsea robotics system capable of providing post lay trenching, inspection and burial (PLIB) and maintenance of submarine cables and flowlines in water depths of 30 to 7,200 feet across a range of seabed and environmental conditions. Ultra-Deepwater: Water depths beyond 4,000 feet. 5

SUBSEA CONTRACTING We and our alliance partners provide a full range of subsea construction services in both the shallow water and Deepwater Gulf including: - 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. Today, our fleet consists of two semi-submersible DP MSVs, the Q4000 and the Uncle John; a dedicated well operations vessel, the Seawell; an umbilical and rigid pipelay vessel, the Intrepid; three construction DP DSVs, the Witch Queen, the Mystic Viking, and the Eclipse; and two ROV support vessels, the Merlin and the Northern Canyon. In 2001, we began vessel enhancements to the Q4000 (well completion) and the Intrepid (DP-2 capability and a 400-ton crane). The Q4000 and Intrepid were placed into service, respectively, in April and May 2002. We purchased the Eclipse in October of 2001 and the Seawell in July of 2002. In 2002, we increased our ROV and trenching fleet to 21 by acquiring Canyon Offshore, Inc. Canyon's ROVs and trenchers are designed for offshore construction, rather than drilling rig support, and its management team added 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 and will help to provide our customers with vessel availability and schedule flexibility to meet the technological challenges of Deepwater construction developments in the Gulf and internationally. Our ROVs operate in three regions: the Americas (8), Southeast Asia (5), and the North Sea (4). In addition to the ROVs, Canyon also has four trenchers that operate in Southeast Asia (2) and the North Sea (2). Furthermore, Canyon has ordered 3 new Triton XLS ROV systems and a state of the art 750 horsepower trenching unit to fulfill its future contract obligations under its agreement with Technip. We assist customers in solving the operational challenges encountered in Deepwater projects by 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 service while maintaining our low overhead base. These alliances are: - Fugro-McClelland Marine Geoscience, Inc. -- Geotechnical coring and survey - Horizon Offshore, Inc. -- Small diameter reeled pipelay equipment - Schlumberger Limited -- Deepwater downhole services 6

Utilization of 82% was very close to last year's record of 87% even though we added three new vessels and elected to take several vessels out of service in the third quarter for accelerated regulatory inspections. Major projects in 2001 and 2002 were:

In late 2002, we formed a new wholly owned subsidiary, Well Ops Inc., to provide offshore oil and gas operators with the industry's largest collection of experience, expertise and technology for cost-effective subsea well operations. Establishment of the Well Ops Group (Well Ops Inc. and Well Ops (U.K.) Limited) follows the construction of the purpose-built Q4000 and the acquisition of the subsea well operations business unit of CSO Ltd., a subsidiary of Technip. The mission of these new companies is to provide the industry with a single, comprehensive source for addressing current well operations needs and to engineer for future needs. Our purpose-built vessels serve as work platforms for well operations services at costs significantly less than drilling rigs. In the Gulf of Mexico, the Q4000 and the Uncle John have set a series of "firsts" in increasingly deep water without the use of a rig including: first "live subsea well" intervention; first through tubing subsea well decommission; first "live subsea well" intervention using wireline lubricator; first Deepwater full field decommission; first re-entry and decommission through horizontal tree; first removal and recovery of subsea well templates and horizontal trees; first use of test tree in open water as a lower riser package (LRP); first subsea transfer of tree from one well to another during decommissioning operations; first use of coil tubing drilling in subsea decommissioning; and first installation of a "storm choke" as replacement for subsurface safety control valve; all of which utilized a semi-submersible DP MSV instead of a drilling rig. The Seawell has provided intervention and abandonment services for more than 400 North Sea wells since her commissioning in 1987. Competitive advantages of our vessels stem from their lower operating costs and the ability to mobilize quickly and maximize productive time by performing a broad range of tasks for intervention, construction, inspection, repair and maintenance. Well Ops Inc. also collaborates with the leading downhole service providers to provide a superior, comprehensive solution. An alliance is currently in place with Schlumberger to provide these services. Shelf Contracting On the OCS in water depths up to 1,000 feet, we perform traditional subsea services including air and saturation diving in support of marine construction activities. Eleven of our vessels are permanently dedicated to performing traditional diving services, with another five DP vessels capable of providing such services, on the OCS. Seven of these vessels 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. We deliver our services in the shallow water market, from the beach to a depth of 300 feet, through our shallow operations division, Aquatica. In addition, our saturation diving vessels can deliver services in depths up to 1,000 feet. We also perform numerous projects on the OCS in an alliance with Horizon. In the late 1980s, we demonstrated that pipelay operations would be much more effective if the expensive barge spreads 7

simply laid the pipe, allowing our DSVs to follow along and perform the more time-consuming task of commissioning the line. Under the alliance, we have the exclusive right to provide DSV and diving services for Horizon pipelay barges, while Horizon supplies pipelay, derrick barge and heavy lift capacity to us. 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. Since 1989, we have undertaken a wide variety of decommissioning assignments, mostly on a turnkey basis. We have established a leading position in the removal of smaller structures, such as caissons and well protectors, which represent approximately half 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, to expand our off-season salvage and decommissioning activity, and to support full field production development projects. Through Production Partnering, we offer customers the option of selling mature offshore fields as an alternative to contracting and managing the many phases of the decommissioning process. The benefits of our Production Partnering strategy are fourfold. First, oil and gas revenues counteract the volatility in revenues we experience in offshore construction. Second, in periods of excess capacity, such as in 2002, we have the flexibility to stay out of the competitive bid market and instead focus on negotiated contracts. Third, our oil and gas operations generate significant cash flow that has partially funded construction and/or modification of assets such as the Q4000, Intrepid and Eclipse, enabling us to add technical talent to support our expansion into the new Deepwater frontier. Finally, a major objective of our investments in oil and gas properties is to secure the associated marine construction work. There are over 100 discoveries in the Deepwater Gulf 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 Gulf will be developed in a hub and satellite field concept that resembles the approach the airline industry has used with regional hub locations. We expect 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, our 50% ownership in the production facility will allow us to realize a return on investment consisting of both a fixed monthly demand charge and a volumetric tariff charge. In addition, we will assist with the installation of the TLP and work to develop the surrounding acreage that can be tied back to the platform by our construction vessels. Within ERT we have assembled a team of personnel with experience in geology, geophysics, reservoir engineering, drilling, production engineering, facilities management, lease operations and land. ERT generates income in three ways: lowering salvage costs by using our assets, operating the field more cost effectively, and extending reservoir life through well exploitation operations. When a company sells an OCS property, they retain the financial responsibility for plugging and decommissioning if their purchaser becomes financially unable to do so. Thus, it becomes important that a property be sold to a purchaser who has the financial wherewithal to perform their contractual obligations. Although there is significant competition in this mature field market, ERT's reputation, supported by Cal Dive's financial strength, have made it the purchaser of choice of many major independent oil and gas companies. Despite this competition we significantly expanded our property base in 2002 with four large acquisitions, including one successful completion of a "stranded" field. In June, ERT acquired a package of offshore properties from Williams Production RMT Company (a subsidiary of the Williams Companies). The blocks purchased represent an average 30% net working interest in 23 federal leases and three Texas leases with 23 wells that produce the equivalent of 7.5 MMcf per day. In August, ERT acquired the 74.8% working interest of subsidiaries of Shell Exploration & Production Company in the South Marsh Island 130 (SMI 130) field and completed the purchase of seven Gulf of Mexico fields from Amerada Hess Corporation, including Hess's 25% interest in SMI 130. Currently the SMI 130 Field, with approximately 155 wells on five 8-pile platforms, produces approximately 4,000 barrels of oil per day from 8

50 active wells. In August 2002, ERT completed the #1 well at East Cameron 374 in three zones using Cal Dive vessels. With production commingled from the lower two zones the well is currently producing at 15.5 MMCFD and 75 BOPD. The completion marked the first Gulf of Mexico application of Baker Oil Tools "Intelligent Well System". The "InForce(TM) Intelligent Well System" allows ERT to change zones via hydraulic controls on the production platform without requiring a rig re-enter the well. This type of completion also minimizes future well maintenance requirements. The table below sets forth information, as of December 31, 2002, with respect to estimates of net proved reserves and the present value of estimated future net cash flows at such date, prepared in accordance with guidelines established by the Securities and Exchange Commission. The Company's estimates of reserves at December 31, 2002, excluding Gunnison, have been reviewed by Miller and Lents, Ltd., independent petroleum engineers. These non-Gunnison reserves totaled (as of December 31, 2002) 43,323 MMcf of natural gas and 6,727 MBbls of oil with a standardized measure of discounted future net cash flows (pre-tax) of $161,565,600 (see note (2) in table below). Since the Company does not own a license to the geophysical data, reserves attributable to Gunnison (which total 47% of our proved reserves as of December 31, 2002) have been determined based on information provided by the operator. These reserve estimates were reviewed by our engineers, including an assessment of the operator's assumptions and their engineering, geologic and evaluation principles and techniques. All of the Company's reserves are located in the United States. Proved reserves cannot be measured exactly because the estimation of 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.

TOTAL PROVED ------------ Estimated Proved Reserves(1): Natural gas (MMcf).......................................... 85,224 Oil and condensate (MBbls).................................. 12,037 Standardized measure of discounted future net cash flows (pre-tax)(2).............................................. $291,705,010
- --------------- (1) Includes both Company's reserves reviewed by Miller & Lents (as noted above) and Gunnison reserves reviewed by Company's engineers. (2) 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, 2002, we owned an interest in 157 gross (105 net) natural gas wells and 302 gross (265 net) oil wells located in federal and state offshore waters in the Gulf of Mexico. CUSTOMERS Our customers include major and independent oil and gas 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: 2002 -- Horizon Offshore, Inc. (10%) and BP Trinidad & Tobago LLC (11%); 2001 -- Horizon Offshore, Inc. (18%) and Enron Corp. (10%) and 2000 -- Enron Corp. (13%). We estimate that in 2002 we provided subsea services to over 200 customers. Our projects are typically of short duration and are 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 acquire specialized vessels, to attract and retain skilled personnel, and to demonstrate a good safety record are also 9

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 Stolt Offshore S.A., Subsea 7, Technip-Coflexip and Torch. ERT encounters significant competition for the acquisition of mature oil and gas properties. 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 potential purchasers of oil and gas properties are well-established companies with substantially larger operating staffs and greater capital resources. TRAINING, SAFETY AND QUALITY ASSURANCE We have established a corporate culture in which safety is expected to be among the highest priorities. Our corporate goal, based on the belief that all accidents are preventable, is to provide an injury-free workplace by focusing on correct safety behavior. Our safety procedures and training programs were developed by management personnel who came into the industry as divers and who know first hand the physical challenges of the ocean work site. As a result, management believes that our safety programs are among the best in the industry. We have introduced a company-wide effort to enhance a behavioral safety process and training program that makes safety a constant focus of awareness through open communication with all offshore and yard employees. The process includes the documentation of all daily observations and the collection of this data. In addition, we initiated regular monthly visits by project managers to conduct "Hazard Hunts" on each vessel, providing a "safety audit" with a fresh perspective. Results from this program were evident as our safety performance improved significantly in 2001 and 2002. GOVERNMENT REGULATION Many aspects of the offshore marine construction industry are subject to extensive governmental regulations. We are subject to the jurisdiction of the Coast Guard, the Environmental Protection Agency, the MMS and the U.S. Customs Service, as well as private industry organizations such as the American Bureau of Shipping. In the North Sea, regulations govern working hours and a specified working environment, as well as standards for diving procedures, equipment and diver health. These North Sea standards are some of the most stringent worldwide. In the absence of any specific regulation, our North Sea branch adheres to standards set by the International Marine Contractors Association and the International Maritime Organisation. 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 oil and gas 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 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. 10

We acquire production rights to offshore mature oil and gas properties under federal oil and gas 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, or 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 OCSLA and the Federal Oil and Gas Royalty Management Act, 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 that are deductible for royalty valuation purposes when natural gas is sold off-lease. Among other matters, for purposes of computing royalties 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 enjoined substantial portions of this rule on March 28, 2000. The United States appealed the district court decision. On February 8, 2002, the Court of Appeals for the District of Columbia reversed the District Court and reinstated the regulations. The United States Supreme Court denied the trade associations' petition for review on January 13, 2003. 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, or NGPA, and the regulations promulgated thereunder by the Federal Energy Regulatory Commission, or FERC. In the past, the federal government has regulated the prices at which oil and gas 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. We cannot predict what further action the FERC will take on these matters, but we do not believe any such action will materially affect us differently than other companies with which we compete. Additional proposals and proceedings before various federal and state regulatory agencies and the courts could affect the oil and gas 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 11

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 national (including federal, state and local) and international 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. Some of the environmental laws and regulations that are applicable to our business operations are discussed in the following paragraphs, but the discussion does not cover all environmental laws and regulations that govern our operations. The Oil Pollution Act of 1990, as amended, or 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 12

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 that 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 oil and gas, 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 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, or 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. We operate in foreign jurisdictions that have various types of governmental laws and regulations relating to the discharge of oil or hazardous substances and the protection of the environment. Pursuant to these laws and regulations, we could be held liable for remediation of some types of pollution, including the release of oil, hazardous substances and debris from production, refining or industrial facilities, as well as other assets we own or operate or which are owned or operated by either our customers or our sub-contractors. Management believes that 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 December 31, 2002, we had 1,184 employees, 227 of which were salaried. As of that date we also utilized approximately 450 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. We believe that our relationship with our employees and foreign crew members is good. 13

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 for 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, but not limited to: - Worldwide economic activity, - Economic and political conditions in the Middle East and other oil-producing regions, - Coordination by the Organization of Petroleum Exporting Countries, or 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 regulations, and - Tax policies. The level of offshore construction activity did not increase despite higher commodity prices in 2002. We cannot assure you that activity levels will increase anytime soon. A sustained period of low drilling and production activity or the return of lower commodity 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 14

prudent, including Jones Act employee coverage, which is the maritime equivalent of workers' compensation, and hull 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 a result of market conditions, premiums and deductibles for certain of our insurance policies have increased substantially, and could escalate further. In some instances, certain insurance could become unavailable or available only for reduced amounts of coverage. For example, insurance carriers are now requiring broad exclusions for losses due to war risk and terrorist acts. As construction activity expands into deeper water in the Gulf, a greater percentage of our revenues may be from Deepwater construction projects that are larger and more complex, and thus riskier, than shallow water projects. As a result, our revenues and profits are increasingly dependent on our larger vessels. The current insurance on our vessels, in some cases, is in amounts approximating book value, which is less than replacement value. In the event of property loss due to a catastrophic marine disaster, mechanical failure or collision, insurance 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 were to lose any of our large vessels. OUR CONTRACTING BUSINESS DECLINES IN WINTER, AND BAD WEATHER IN THE GULF OR NORTH SEA CAN ADVERSELY AFFECT OUR OPERATIONS. Marine operations conducted in the Gulf and North Sea 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. We typically 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, our results in any one quarter are not necessarily indicative of annual results or continuing trends. IF WE BID TOO LOW ON A TURNKEY CONTRACT, WE SUFFER 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 billed 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 the 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 OIL AND GAS RESERVES, FUTURE CASH FLOWS AND ABANDONMENT COSTS MAY BE SIGNIFICANTLY INCORRECT. Our proved reserves at December 31, 2002, included the reserves assigned to our ownership position in the Gunnison project, a Deepwater Gulf of Mexico oil and gas field operated by Kerr-McGee Corporation. These reserves constitute 47% of our total proved reserves as of December 31, 2002. The reserves assigned to Gunnison were not generated by our reservoir engineers, as we do not own the seismic data for the three fields that comprise Gunnison. Instead, they were determined based on information provided by the operator, Kerr-McGee Oil & Gas Corporation. These reserve estimates were reviewed by our engineers, including an assessment of the operator's assumptions and their engineering, geologic and evaluation principles and techniques. This Annual Report also contains estimates of our other proved oil and gas reserves and the estimated future net cash flows therefrom based upon reports for the years ended December 31, 2000, 2001 and 2002, reviewed by Miller and Lents, Ltd., independent petroleum engineers. These reports rely upon various assumptions, including assumptions required by the Securities and Exchange Commission, as to oil and gas prices, drilling and operating expenses, capital expenditures, abandonment costs, taxes and availability of funds. The process of estimating oil and gas 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, 15

development expenditures, operating and abandonment expenses and quantities of recoverable oil and gas 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 prospectus is the current market value of our estimated oil and gas 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. THE GUNNISON PROJECT MAY NOT RESULT IN THE EXPECTED CASH FLOWS OR SUBSEA ASSET UTILIZATION WE ANTICIPATE AND COULD INVOLVE SIGNIFICANT FUTURE CAPITAL OUTLAYS. The Gunnison project 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 we have contracts for subsea construction work, the extent of utilization of our subsea assets for such work has not been fully determined. We have a $35.0 million loan facility to provide for the financing of part of our portion of the construction costs of the spar, of which we had drawn down $29.3 million as of December 31, 2002. See "Management's Discussion and Analysis of Financial Condition and Results of Operations -- Liquidity and Capital Resources." EXPECTED CASH FLOWS FROM THE Q4000, INTREPID AND SEAWELL, AS WELL AS CANYON, MAY NOT BE IMMEDIATE OR AS HIGH AS EXPECTED. The Q4000, Intrepid and the Seawell are vessels that were placed into service during 2002. In addition, during 2002 we acquired Canyon Offshore, Inc., a supplier of ROVs to the offshore construction and telecommunications industry. We will not receive any material increase in revenue or cash flow from their operation until there is significant utilization of these vessels and Canyon's services. We cannot assure you that customer demand for these vessels and Canyon's services will be as high as currently anticipated and, as a result, our future cash flows may be adversely affected. New vessels from third parties may also enter the market in the coming years and compete with the Q4000, Intrepid and the Seawell for contracts. OUR OIL AND GAS OPERATIONS INVOLVE SIGNIFICANT RISKS, AND WE DO NOT HAVE INSURANCE COVERAGE FOR ALL RISKS. Our oil and gas operations are subject to risks incident to the operation of oil and gas wells, including, but not limited to, uncontrollable flows of oil, 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. 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 or the North Sea, 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 AND RETAIN OTHER HIGHLY QUALIFIED PERSONNEL IN THE FUTURE, COULD DISRUPT OUR OPERATIONS AND ADVERSELY AFFECT OUR FINANCIAL RESULTS. Our industry has lost a significant number of experienced subsea people over the years due to, among other reasons, the volatility 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 16

success and continued growth are also dependent upon our ability to attract 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. IF WE FAIL TO EFFECTIVELY MANAGE OUR GROWTH, OUR RESULTS OF OPERATIONS COULD BE HARMED. We have a history of growing through acquisitions of large assets and acquisitions of companies. We must plan and manage our acquisitions effectively to achieve revenue growth and maintain profitability in our evolving market. If we fail to effectively manage current and future acquisitions, our results of operations could be adversely affected. Our growth has placed, and is expected to continue to place, significant demands on our personnel, management and other resources. We must continue to improve our operational, financial, management and legal/compliance information systems to keep pace with the growth of our business. WE MAY NEED TO CHANGE THE MANNER IN WHICH WE CONDUCT OUR BUSINESS IN RESPONSE TO CHANGES IN GOVERNMENT REGULATIONS. Our subsea construction, intervention, inspection, maintenance and decommissioning operations and our oil and gas 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 protection laws and regulations. These laws and regulations are becoming increasingly complex, stringent and expensive to comply with, and significant fines and penalties may be imposed for noncompliance. We cannot assure you that continued compliance with existing or future laws or regulations will not adversely affect our operations. CERTAIN PROVISIONS OF OUR CORPORATE DOCUMENTS AND MINNESOTA LAW MAY DISCOURAGE A THIRD PARTY FROM MAKING A TAKEOVER PROPOSAL. In addition to the 55,000 shares of preferred stock issued or issuable to Fletcher International, Ltd. under the First Amended and Restated Agreement dated January 17, 2003, but effective as of December 31, 2002, by and between Cal Dive and Fletcher International, Ltd., our board of directors has the authority, without any action by our shareholders, to fix the rights and preferences on up to 4,945,000 shares of undesignated preferred stock, including dividend, liquidation and voting rights. In addition, our by-laws 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 that 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 a fleet of 22 vessels and 21 ROVs and trenchers. We believe that the Gulf market requires specially designed and/or equipped vessels to competitively deliver subsea construction services. Nine of our vessels have DP capabilities specifically designed to respond to the Deepwater market requirements. Eight of our vessels (seven of which are based in the Gulf) have the capability to provide saturation diving services. Recent developments in our fleet include: Q4000: We began construction of our newest Ultra-Deepwater MSV, the Q4000, in 1999, and accepted her delivery in early 2002. The vessel cost $182 million and incorporates our latest semi-submersible technologies, including various patented elements such as the absence of lower hull cross bracing. A variable deck load of over 4,000 metric tons and upgraded well completions capability make 17

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. Intrepid: The Intrepid (formerly Sea Sorceress) offers customers a pipelay/construction vessel capable of carrying an 8,000 metric ton deck load. She began work in June of 2002. Eclipse: This large DP DSV is 370 feet long, 67 feet wide and has recently been refitted into a DSV by installing a saturation diving system, restoring the ballast system and upgrading to DP-2. The Eclipse began work in March 2002. Seawell: This purpose-built 364 foot mono-hull DP vessel, capable of supporting both manned diving and ROVs, was recently upgraded for coiled tubing deployment and well testing. The Seawell was purchased in July 2002. Northern Canyon: Canyon took delivery of this purpose-built, 270 foot state-of-the-art ROV support vessel in July 2002. The vessel, which is deployed in the North Sea, is leased from a third party. ROVs: To enable us to control critical path equipment involved in our deepwater projects, we acquired Canyon in January 2002. Canyon currently operates 17 ROVs and four trencher 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. The average age of the Canyon ROV fleet is approximately two years. Furthermore, Canyon has ordered three new Triton XLS ROV systems and a state of the art 750 horsepower trenching unit to fulfill its future contract obligations under its agreement with Technip. 18

- --------------- (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 American Bureau of Shipping, or ABS, Det Norske Veritas, or DNV, and the U.S. Coast Guard, or USCG. 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. (2) The Q4000 commenced work in April 2002. (3) This leased vessel became available in June 2002. (4) The Intrepid modifications were completed in May 2002 and the vessel began work in June 2002. 19

(5) The Eclipse was purchased in October 2001 and began work in March 2002. (6) The Seawell was purchased and began work in July 2002. (7) In March 2001, we acquired substantially all of the assets of Professional Divers including the Mr. Sonny (a 165-foot four-point moored DSV), three utility vessels and associated diving equipment including two saturation diving systems. (8) Average age of ROV fleet is two years. 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 that we believe 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 $70.0 million revolving credit facility, except the Northern Canyon (leased),and the Q4000 (subject to liens to secure the MARAD financing guarantees). SUMMARY OF NATURAL GAS AND OIL RESERVE DATA The table below sets forth information, as of December 31, 2002, with respect to estimates of net proved reserves and the present value of estimated future net cash flows at such date, prepared in accordance with guidelines established by the Securities and Exchange Commission. The Company's estimates of reserves at December 31, 2002, excluding Gunnison, have been reviewed by Miller and Lents, Ltd., independent petroleum engineers. These non-Gunnison reserves totaled (as of December 31, 2002) 43,323 MMcf of natural gas and 6,727 MBbls of oil with a standardized measure of discounted future net cash flows (pre-tax) of $161,565,600 (see note (2) in table below). Since the Company does not own a license to the geophysical data, reserves attributable to Gunnison (which total 47% of the proved reserves as of December 31, 2002) have been determined based on information provided by the operator. These reserve estimates were reviewed by our engineers, including an assessment of the operator's assumptions and their engineering, geologic and evaluation principles and techniques. All of the Company's reserves are located in the United States. Proved reserves cannot be measured exactly because the estimation of 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.

- --------------- (1) Includes both Company's reserves reviewed by Miller & Lents (as noted above) and Gunnison reserves reviewed by Company's engineers. (2) 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, 2002, we owned an interest in 157 gross (105 net) natural gas wells and 302 gross (265 net) oil wells located in federal and state offshore waters in the Gulf of Mexico. 20

ITEM 3. 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 our vessel, the Balmoral Sea, was fully 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, we believe 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, in 1998, one of our subsidiaries entered into a subcontract with Seacore Marine Contractors Limited ("Seacore") to provide the Sea Sorceress to a Coflexip subsidiary in Canada ("Coflexip"). Due to difficulties with respect to the sea states and soil conditions the contract was terminated and an arbitration to recover damages was commenced. A preliminary liability finding has been made by the arbitrator against Seacore and in favor of the Coflexip subsidiary. We were not a party to this arbitration proceeding. Seacore and Coflexip 21

settled this matter prior to the conclusion of the arbitration proceeding with Seacore paying Coflexip $6.95 million CDN. Seacore has now made demand on Cal Dive Offshore Ltd. ("CDO"), a subsidiary of Cal Dive, for one-half of this amount. Because only one of the grounds in the preliminary findings by the arbitrator is applicable to CDO, and because CDO holds substantial counterclaims against Seacore, management believes that in the event Seacore continues to seek contribution from our subsidiary, which would require another arbitration, it is anticipated that our subsidiary's exposure, if any, should be less than $500,000. During 2002, the Company engaged in a large construction project and, in late September, supports engineered by a subcontractor failed resulting in over a month of downtime for two of CDI's vessels. Management believes that under the terms of the contract the Company is entitled to the contractual stand-by rate for the vessels during their downtime. The customer is currently disputing these invoices along with certain other change orders. Of the amounts billed by CDI for this project, $12.1 million had not been collected as of February 18, 2003. Due to the size of the dispute, inherent uncertainties with respect to a mediation and relationship issues with the customer, CDI provided a reserve in the fourth quarter of 2002 resulting in a loss for the Company on the project as a whole. In another lengthy 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 had responded alleging EEX Corporation breached various provisions of the same contracts. EEX's acquisition by Newfield during the fourth quarter 2002 enabled CDI to enter meaningful settlement discussions prior to the trial date, which was set for February 2003. This resulted in a settlement including CDI making a cash payment, subsequent to yearend, and agreeing to provide work credits for its services over the next three years. The total value of the settlement was recorded in the Company's statement of operations for the year ended December 31, 2002. This settlement combined with the reserves on the project discussed above resulted in approximately $10 million of pre-tax charges recorded in the accompanying statement of operations. ITEM 4.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS OVERVIEW Oil and gas prices, the offshore mobile rig count, and Deepwater construction activity are three of the primary indicators we use 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 oil and gas prices. In the second quarter of 1999, oil prices reached their highest levels since the First Gulf War and natural gas prices reached $10.00 per Mcf in early 2001, pushing offshore mobile rig utilization rates back to virtually full utilization. However, a slowing world economy and record levels of natural gas in storage resulted in significantly lower offshore mobile rig utilization rates in the second half of 2001 and throughout 2002. Commodity prices have recently recovered to very robust levels; however, with the instability in the Middle East and a slow world economy, drilling activity has yet to respond. Our primary leading indicator, the number of offshore mobile rigs contracted, is currently at approximately 115 rigs employed in the Gulf of Mexico, compared to 182 during the first quarter of 2001. The Deepwater Gulf is principally being developed for oil, with the complexity of developing these reservoirs resulting in significant lead times to first production. Product prices impact our oil and gas operations in several respects. We seek to acquire producing oil and gas properties that are generally in the later stages of their economic life. The sellers' potential abandonment liabilities are 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. In contrast, lower natural gas prices, typically contribute to lower operating results for ERT and a general increase in the number of mature properties available for sale. We have expanded the scope of our gas and oil operations by taking a working interest in Gunnison, a Deepwater Gulf development of Kerr-McGee Oil & Gas Corporation which has discovered significant reserves, and participating 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 and the North Sea. 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 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. Operation of oil and gas 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. 26

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.

CRITICAL ACCOUNTING POLICIES Our results of operations and financial condition, as reflected in the accompanying financial statements and related footnotes, are subject to management's evaluation and interpretation of business conditions, changing capital market conditions and other factors which could affect the ongoing viability of our business segments and/or our customers. We believe 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. While these issues require us to make judgments that are somewhat subjective, they are generally based on a significant amount of historical data and current market data. Another area which requires us to make subjective judgments is that of revenue recognition. Our 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. We recognize 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 fair 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, we perform detailed estimating procedures, including engineering studies. We follow the successful efforts method of accounting for our interests in oil and gas 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. 27

The Company also considers the following accounting policies to be the most critical to the preparation of its financial statements: GOODWILL AND INDEFINITE-LIVED INTANGIBLES In accordance with SFAS No. 142, Goodwill and Indefinite-Lived Intangibles ("SFAS No. 142"), the Company tests for the impairment of goodwill and other intangible assets with indefinite lives on at least an annual basis. The Company's goodwill impairment test involves a comparison of the fair value of each of the Company's reporting units, as defined under SFAS No. 142, with its carrying amount. The Company's indefinite-lived asset impairment test involves a comparison of the fair value of the intangible and its carrying value. The fair value is determined using discounted cash flows and other market-related valuation models, such as earnings multiples and comparable asset market values. These tests are influenced significantly by management estimates of future cash flows and the related expected utilization of assets. Prior to the adoption of SFAS No. 142, goodwill was amortized on a straight line basis over 25 years. In conjunction with the adoption of this statement, the Company has discontinued the amortization of goodwill. PROPERTY AND EQUIPMENT Property and equipment, both owned and under capital leases, are recorded at cost. Depreciation is provided primarily on the straight-line method over the estimated useful lives of the assets. In accordance with Statement of Financial Accounting Standards ("SFAS") No. 144, Accounting for the Impairment or Disposal of Long-Lived Assets ("SFAS No. 144"), long-lived assets, excluding goodwill and indefinite-lived intangibles, to be held and used by the Company are reviewed to determine whether any events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable. SFAS No. 144 modifies SFAS No. 121, Accounting for the Impairment or Disposal of Long-Lived Assets to be Disposed of ("SFAS No. 121"). For long-lived assets to be held and used, the Company bases its evaluation on impairment indicators such as the nature of the assets, the future economic benefit of the assets, any historical or future profitability measurements and other external market conditions or factors that my be present. If such impairment indicators are present or other factors exist that indicate that the carrying amount of the asset may not be recoverable, the Company determines whether an impairment has occurred through the use of an undiscounted cash flows analysis of the asset at the lowest level for which identifiable cash flows exist. If an impairment has occurred, the Company recognizes a loss for the difference between the carrying amount and the fair value of the asset. The fair value of the asset is measured using quoted market prices or, in the absence of quoted market prices, is based on management's estimate of discounted cash flows. Assets are classified as held for sale when the Company has a plan for disposal of certain assets and those assets meet the held for sale criteria of SFAS No. 144. FOREIGN CURRENCY The functional currency for the Company's foreign subsidiary Well Ops (U.K.) Limited is the applicable local currency (British Pound). Results of operations for this subsidiary are translated into U.S. dollars using average exchange rates during the period. Assets and liabilities of this foreign subsidiary are translated into U.S. dollars using the exchange rate in effect at the balance sheet date and the resulting translation adjustment which was a gain of $2.5 million, net of taxes, in 2002 is accumulated as a component of shareholders' equity. All foreign currency transaction gains and losses are recognized currently in the statements of operations. Canyon Offshore, the Company's ROV subsidiary, has operations in the United Kingdom and Southeast Asia sectors. Canyon conducts the majority of its affairs in these regions in U.S. dollars which it considers the functional currency. When currencies other than the U.S. dollar are to be paid or received the resulting gain or loss from translation is recognized in the statements of operations. These amounts for the year ended December 31, 2002 were not material to the Company's results of operations or cash flows. 28

ACCOUNTING FOR PRICE RISK MANAGEMENT ACTIVITIES The Company's price risk management activities involve the use of derivative financial instruments to hedge the impact of market price risk exposures primarily related to our oil and gas production. Under SFAS No. 133, Accounting for Derivative Instruments and Hedging Activities, all derivatives are reflected in our balance sheet at their fair market value. Under SFAS No. 133 there are two types of hedging activities: hedges of cash flow exposure and hedges of fair value exposure. The Company engages primarily in cash flow hedges. Hedges of cash flow exposure are entered into to hedge a forecasted transaction or the variability of cash flows to be received or paid related to a recognized asset or liability. Changes in the derivative fair values that are designated as cash flow hedges are deferred to the extent that they are effective and are recorded as a component of accumulated other comprehensive income until the hedged transactions occur and are recognized in earnings. The ineffective portion of a cash flow hedge's change in value is recognized immediately in earnings in oil and gas production revenues. As required by SFAS No. 133, we formally document all relationships between hedging instruments and hedged items, as well as our risk management objectives, strategies for undertaking various hedge transactions and our methods for assessing and testing correlation and hedge ineffectiveness. All hedging instruments are linked to the hedged asset, liability, firm commitment or forecasted transaction. We also assess, both at the inception of the hedge and on an on-going basis, whether the derivatives that are used in our hedging transactions are highly effective in offsetting changes in cash flows of the hedged items. We discontinue hedge accounting prospectively if we determine that a derivative is no longer highly effective as a hedge. The market value of hedging instruments reflects our best estimate and is based upon exchange or over-the-counter quotations whenever they are available. Quoted valuations may not be available due to location differences or terms that extend beyond the period for which quotations are available. Where quotes are not available, we utilize other valuation techniques or models to estimate market values. These modeling techniques require us to make estimations of future prices, price correlation and market volatility and liquidity. Our actual results may differ from our estimates, and these differences can be positive or negative. During the second half of 2002, the Company entered into various cash flow hedging swap contracts to fix cash flows relating to a portion of the Company's oil and gas production. All of these qualified for hedge accounting and none extended beyond a year and a half. The aggregate fair market value of the swaps was a liability of $4.1 million as of December 31, 2002. The Company recorded $2.6 million of loss, net of taxes, in other comprehensive loss within shareholders' equity as these hedges were highly effective. NEW ACCOUNTING PRONOUNCEMENTS In July 2001, the Financial Accounting Standards Board ("FASB") released SFAS No. 143, Accounting for Asset Retirement Obligations, which is required to be adopted no later than January 1, 2003. SFAS 143 addresses the financial accounting and reporting obligations and retirement costs related to the retirement of tangible long-lived assets. Among other things, SFAS 143 will require oil and gas companies to reflect decommissioning liabilities on the face of the balance sheet at fair value on a discounted basis. Historically, ERT has reflected this liability on the balance sheet on an undiscounted basis. The Company will adopt this standard, as required, effective January 1, 2003. Management currently believes adoption of this standard will result in additional diluted earnings per share in the first quarter of 2003 of between $0.01 and $.03 and adjustments to certain balance sheet accounts including a decrease in Decommissioning Liabilities of approximately $30 million due to discounting. In November 2002, FASB interpretation ("FIN") No. 45, Guarantor's Accounting and Disclosure Requirements for Guarantees, Including Indirect Guarantees of Indebtedness of Others ("FIN No. 45") was issued. FIN No. 45 requires a guarantor to recognize at the inception of a guarantee a liability for the fair value of the obligation undertaken in issuing the guarantee. FIN No. 45 also expands the disclosures required to be made by a guarantor about its obligations under certain guarantees that it has issued. Initial recognition and measurement provisions of FIN No. 45 are applicable on a prospective basis to guarantees issued or 29

modified. The disclosure requirements are effective immediately. The Company does not expect FIN No. 45 to have a material effect on its consolidated financial statements. In January 2003, FIN No. 46, Consolidation of Variable Interest Entities was issued which requires that companies that control another entity through interests other than voting interests should consolidate the controlled entity. FIN No. 46 applies immediately to variable interest entities created after January 31, 2003, and applies in the first interim period beginning after June 15, 2003 to variable interest entities created before February 1, 2003. The related disclosure requirements are effective immediately. The Company does not believe that the adoption of this interpretation will have a material impact on its consolidated financial statements. RESULTS OF OPERATIONS COMPARISON OF YEARS ENDED 2002 AND 2001 Revenues. During the year ended December 31, 2002, the Company's revenues increased $75.6 million, or 33%, to $302.7 million compared to $227.1 million for the year ended December 31, 2001 with the Subsea and Salvage segment contributing all of the increase. Subsea and Salvage revenues increased to $239.9 million for the year ended December 31, 2002 as compared to $163.7 million in the prior year. Our acquisitions of Canyon Offshore and Well Ops UK Ltd added $37.5 million and $21.4 million, respectively. The remainder of the increase is due to the addition of three deepwater construction vessels: the Q4000, the Intrepid and the Eclipse. Oil and Gas Production revenue for the year ended December 31, 2002 decreased less than 1% to $62.8 million from $63.4 million during the prior year. An increase in production, lead by the significant Shell and Hess acquisitions made late in the third quarter of 2002, was offset by lower average realized commodity prices. Oil and gas production increased 19% to 16.6 Bcfe in 2002 from 13.9 Bcfe during 2001, while our average realized commodity price declined 15% to $3.71 per Mcfe ($3.39 per Mcf of natural gas and $25.54 per barrel of oil) in 2002 as compared to $4.37 per Mcfe ($4.44 per Mcf of natural gas and $24.54 per barrel of oil) in the prior year. Oil and condensate represented 38% of ERT revenue in 2002 compared to 30% in 2001. Gross Profit. Gross profit of $53.8 million for the year ended December 31, 2002 was $13.1 million, or 20%, below the $66.9 million gross profit recorded in the prior year with both segments contributing to the decline. Subsea and Salvage gross profit decreased $9.6 million, or 26%, to $27.0 million during the year ended December 31, 2002 compared to $36.7 million during 2001. Our DP vessels generated $8.6 million of gross profit, only 43% of the $20.1 million generated in the prior year, due in part to the charges recorded in the fourth quarter related to a contract dispute. Margins for this segment decreased to 11% for the year ended December 31, 2002 compared to 22% in 2001. While Aquatica margins held strong at 30% due to a large amount of shelf repair work following Hurricane Lili, the DP fleet only contributed 7% margins in 2002 compared to 25% in the prior year. Oil and Gas Production gross profit decreased $3.5 million from $30.2 million in the year ended December 31, 2001 to $26.7 million for the year ended December 31, 2002 due mainly to the aforementioned decrease in average realized commodity prices. Margins declined to 43% during 2002 from 48% during 2001 due to platform repairs and the time necessary for pipelines to return to full production following Hurricane Lili. Selling and Administrative Expenses. Selling and administrative expenses of $32.8 million in 2002 were $11.5 million, or 54%, higher than the $21.3 million incurred during 2001. The increase is primarily due to the acquisitions of Canyon and Well Ops UK Ltd. and a charge taken for the settlement of litigation in the fourth quarter of 2002. Net Interest (Income) Expense and Other. The Company reported net interest expense and other of $2.0 million for the year ended December 31, 2002 in contrast to $1.3 million for the prior year. This increase is due to the increase in debt from our capital program, which resulted in an additional $2.2 million in interest expense, offset by a $1.1 million gain on our foreign currency hedge related to the Well Ops (U.K.) Limited acquisition included in other income in the third quarter of 2002. 30

Income Taxes. Income taxes decreased to $6.7 million for the year ended December 31, 2002, compared to $15.5 million in the prior year due to decreased profitability. Federal income taxes were provided at the statutory rate of 35% in 2002. 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 2002 and 2001. Since the deduction of Q4000 construction costs affects financial and taxable income in different years, the entire 2002 and 2001 provisions for federal taxes were reflected as deferred income taxes. Net Income. Net income of $12.4 million for the year ended December 31, 2002 was $16.6 million, or 57%, less than the $28.9 million earned in 2001 as a result of factors described above. 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). Oil and Gas 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% greater than the $55.4 million gross profit recorded in the prior year with Subsea and Salvage contracting gross profit providing all of the increase and offsetting a $9.1 million decline in oil and gas 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. Oil and Gas 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 a $1.0 million charge for 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 as 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 31

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. LIQUIDITY AND CAPITAL RESOURCES During the three years following our initial public offering in 1997, internally generated cash flow funded approximately $164 million of capital expenditures and enabled us to remain essentially debt-free. In August 2000, we closed the long-term MARAD 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. We refer to this debt as 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. Through December 31, 2002, we have drawn $143.5 million on this facility. In January 2002, we acquired Canyon Offshore, Inc., in July 2002 we acquired the Well Operations Business Unit of Technip-Coflexip and in August 2002, ERT made two significant property acquisitions (see further discussion below). These acquisitions have significantly increased our debt to total book capitalization ratio from 31% at December 31, 2001 to 40% at December 31, 2002. Additionally, increased operations coupled with depressed market conditions have caused our working capital to decrease from $48.6 million at December 31, 2001 to $4.4 million at December 31, 2002. In order to reduce this leverage, on January 8, 2003, CDI completed the private placement of $25 million of a newly designated class of cumulated convertible preferred stock (Series A-1 Cumulative Convertible Preferred Stock, par value $0.01 per share) which is convertible into 833,334 shares of Cal Dive common stock at $30 per share. Operating Activities. Net cash provided by operating activities was $65.2 million during the year ended December 31, 2002, as compared to $89.1 million during 2001. This decrease was due mainly to decreased profitability and to last year's collection of a $10 million tax refund from the Internal Revenue Service relating to the deduction of Q4000 construction costs as research and development expenditures for federal tax purposes. Depreciation and amortization also increased $10.2 million to $44.8 million due to the depreciation of new vessels placed in service during 2002 and to increased depletion related to increased production levels from ERT. This was offset by an increase in funding required for accounts receivable collections during 2002 compared to 2001. 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 the $10 million tax refund from the Internal Revenue Service noted above. 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. Investing Activities. Capital expenditures have consisted principally of strategic asset acquisitions related to the purchase of DP vessels, the Eclipse and Mystic Viking; construction of the Q4000 and conversion of the Intrepid; acquisition of Aquatica, Professional Divers, Canyon Offshore, Inc. and Well Ops (U.K.) Limited; improvements to existing vessels and the acquisition of oil and gas properties. As a result of our anticipation of an acceleration in Deepwater demand over the next several years, we incurred $316.4 million of capital expenditures (including the acquisitions of Canyon and Well Ops (U.K.) Limited and investments in 32

the two Deepwater developments, Gunnison and Deepwater Gateway L.L.C.) during 2002, $151.3 million during 2001 and $95.1 million in 2000. We incurred $161.8 million of capital expenditures during the year ended December 31, 2002, compared to $151.3 million during the prior year. Included in the capital expenditures in 2002 is $29.1 million for the construction of the Q4000 and $20.8 million relating to the Intrepid DP conversion and Eclipse upgrade. Also included is over $25 million in ERT offshore property acquisitions (see discussion below) as well as approximately $53 million related to Gunnison development costs, including the spar. Included in the $151.3 million of capital expenditures in 2001 is $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 Professional Divers of New Orleans in exchange for $11.5 million. The assets purchased included the 165-foot four-point moored DSV 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 goodwill. On August 30, 2002, ERT acquired the 74.8% working interest of Shell Exploration & Production Company in the South Marsh Island 130 (SMI 130) field. ERT paid $10.3 million in cash and assumed Shell's pro-rata share of the related decommissioning liability. ERT also completed the purchase of interests in seven Gulf of Mexico fields from Amerada Hess including its 25% ownership position in SMI 130 for $9.3 million in cash and assumption of Amerada Hess' pro-rata share of the related decommissioning liability. As a result, ERT is the operator with an effective 100% working interest in that field. In July 2002, CDI purchased the Subsea Well Operations Business Unit of CSO Ltd., a wholly owned subsidiary of Technip-Coflexip, for approximately $72.0 million ($68.6 million cash and $3.4 million deferred tax liability assumption). Well Ops (U.K.) Limited performs life of field well operations and marine construction tasks primarily in the North Sea. The assets purchased include the Seawell, a 368-foot DPDSV capable of supporting manned diving, ROVs and well operations. The acquisition was accounted for as a business purchase with the acquisition price allocated to the assets acquired and liabilities assumed based upon their estimated fair values, with the excess being recorded as goodwill. During the fourth quarter of 2002 the Company completed its purchase price allocation, including obtaining an appraisal of the Seawell, resulting in $50 million allocated to this vessel, $1.5 million allocated to patented technology (to be amortized over 20 years) and goodwill of approximately $20.6 million as of December 31, 2002. The results of Well Ops (U.K.) Limited are included in the accompanying statements of operations since the date of the purchase, July 1, 2002. In January 2002, CDI purchased Canyon, a supplier of remotely operated vehicles (ROVs) and robotics to the offshore construction and telecommunications industries. CDI purchased Canyon for cash of $52.8 million, the assumption of $9.0 million of Canyon debt (offset by $3.1 million of cash acquired), 181,000 shares of our common stock (143,000 shares of which we purchased as treasury shares during the fourth quarter of 2001) and a commitment to purchase the redeemable stock in Canyon at a price to be determined by Canyon's performance during the years 2002 through 2004 from continuing employees at a minimum purchase price of $13.53 per share. As they are employees, amounts paid, if any, in excess of the $13.53 per share will be recorded as compensation expense. No such expense was recorded in 2002. These remaining shares have been classified as redeemable stock in subsidiary in the accompanying balance sheet and will be adjusted to their estimated redemption value at each reporting period based on Canyon's performance. The acquisition was accounted for as a purchase with the acquisition price allocated to the assets acquired and liabilities assumed based upon their estimated fair values, with the excess being recorded as goodwill. The allocation of the $70.5 million purchase price was as follows: ROVs and equipment ($22.9 million); net working capital assumed ($4.0 million) and goodwill ($43.6 million). The results of Canyon are included in the accompanying statements of operations since the date of the purchase, January 2, 2002. 33

In April 2002, ERT acquired a 100% interest in East Cameron Block 374, including existing wells, equipment and improvements. The property, located in 425 feet of water, was jointly owned by Murphy Exploration & Production Company and Callon Petroleum Operating Company. Terms included a cash payment of approximately $3 million to reimburse the owners for the inception-to-date cost of the subsea wellhead and umbilical and an overriding royalty interest in future production. Cal Dive completed the temporarily abandoned number one well and performed a subsea tie-back to host platform. The cost of completion and tie-back was approximately $7 million with first production occurring in August 2002. In June 2002, ERT acquired a package of offshore properties from Williams Exploration and Production. ERT paid $4.9 million and assumed the pro-rata share of the abandonment obligation for the acquired interests. The blocks purchased represent an average 30% net working interest in 26 Gulf of Mexico leases. In early 2002, CDI, along with El Paso Energy Partners, formed Deepwater Gateway L.L.C. (a 50/50 venture) to design, construct, install, own and operate a tension leg platform ("TLP") production hub primarily for Anadarko Petroleum Corporation's Marco Polo field discovery in the Deepwater Gulf of Mexico. Our share of the construction costs is estimated to be approximately $110 million (approximately $43 million of which had been incurred as of December 31, 2002). In August 2002, the Company along with El Paso, completed a non-recourse project financing for this venture, terms of which include a minimum equity investment for CDI of $33 million, all of which had been paid as of December 31, 2002 and is recorded as Investment in Deepwater Gateway L.L.C. in the accompanying consolidated balance sheet. Terms of the financing also require CDI to guarantee a balloon payment at the end of the financing term in 2008 (estimated to be $22.5 million). The Company has not recorded any liability for this guarantee as management does not believe performance is likely to occur. 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 of approximately $20 million was provided by an investment partnership (OKCD Investments, Ltd.), the investors of which are CDI senior management, in exchange for an overriding royalty interest of 25% of CDI's 20% working interest. CDI provided no guarantees to the investment partnership. 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. With the sanctioning of a commercial discovery, the Company is funding ongoing development and production costs. Cal Dive's share of such project development costs is estimated in a range of $100 million to $110 million ($63.3 million of which had been incurred by December 31, 2002) with over half of that for construction of the spar. See footnote 10 to the Company's Consolidated Financial Statements included herein for discussion of financing relating to the spar construction. 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, we closed a $138.5 million long-term financing for construction of the Q4000. 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. During 2001 and 2002, we borrowed $59.5 million and $43.9 million, respectively, on this facility bringing the total to $142.1 million at December 31, 2002. The MARAD debt is payable in equal semi-annual installments beginning in August 2002 and maturing 25 years from such date. It is collateralized by the Q4000, with Cal Dive 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 (approximately 2% as of December 31, 2002). For a period up to ten years from delivery of the vessel in April 2002, the Company has options to lock in a fixed rate. In accordance with the MARAD debt agreements, we are required to comply with certain covenants and restrictions, including the maintenance of minimum net worth, working capital and debt-to-equity requirements. As of December 31, 2002, we were in compliance with these covenants. 34

The Company has a revolving credit facility which was increased from $40 million to $70 million during 2002 and the term extended for 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 (approximately 4.2% as of December 31, 2002) and, among other restrictions, includes three financial covenants (cash flow leverage, minimum interest coverage and fixed charge coverage). As of December 31, 2002, the Company had drawn $52.6 million under this revolving credit facility and was in compliance with these covenants with the exception of the cash flow leverage covenant, for which the Company obtained a waiver. In November 2001, ERT entered into a five-year lease transaction with an entity owned by a third party to fund CDI's portion of the construction costs ($67 million) of the spar for the Gunnison field. As of December 31, 2001 and June 30, 2002, the entity had drawn down $5.6 million and $22.8 million, respectively, 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. In August 2002, CDI acquired 100% of the equity of the entity and converted the notes into a term loan ("Gunnison Term Loan"). The total commitment of the loan was reduced to $35 million and will be payable in quarterly installments of $1.75 million for three years after delivery of the spar with the remaining $15.75 million due at the end of the three years. The facility bears interest at LIBOR plus 225-300 basis points depending on CDI leverage ratios (approximately 4.4% as of December 31, 2002) 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, 2002 with the exception of the cash flow leverage covenant, for which the Company obtained a waiver. The debt ($29.3 million at December 31, 2002) and related asset have been reflected on CDI's balance sheet beginning in the third quarter of 2002. The purchase price was allocated entirely to construction in progress. In May 2002, CDI sold 3.4 million shares of primary common stock for $23.16 per share, along with 517,000 additional shares to cover over-allotments. Net proceeds to the Company of approximately $87.2 million were used for the Coflexip Well Operation acquisition, ERT acquisitions and to retire debt under the Company's revolving line of credit. During 2002, we made payments of $5.2 million on capital leases assumed in the Canyon acquisition. The only other financing activity during 2002, 2001 and 2000 involved the exercise of employee stock options. In January 2003, CDI completed the private placement of $25 million of preferred stock which is convertible into 833,334 shares of CDI common stock at $30 per share. The preferred stock was issued to a private investment firm. The preferred stock holder has the right to purchase as much as $30 million in additional preferred stock for a period of two years beginning in July, 2003. The conversion price of the additional preferred stock will equal 125% of the then prevailing price of Cal Dive common stock, subject to a minimum conversion price of $30 per common share. After the second anniversary, the holder may redeem the value of its original investments in the preferred shares to be settled in common stock or cash at the discretion of the Company. Under certain conditions, the holder could redeem its investment prior to the second anniversary. Prior to the conversion, shares will be included in the Company's fully diluted earnings per share under the if converted method based on the Company's average common share price during the applicable period. Subsequent to year-end the Company filed a registration statement registering approximately 7.5 million shares of common stock relating to this transaction, the maximum potential total number of shares of common stock redeemable under certain circumstances, subject to the Company's ability to redeem with cash, under the terms of the agreement. 35

The following table summarizes our contractual cash obligations as of December 31, 2002 and the scheduled years in which the obligation are contractually due:

LESS THAN (IN THOUSANDS) TOTAL 1 YEAR 2-3 YEARS 4-5 YEARS THEREAFTER - -------------- -------- --------- --------- --------- ---------- MARAD debt......................... $142,128 $ 2,766 $ 6,093 $ 6,925 $126,344 Gunnison term debt................. 29,270 -- 14,000 15,270 -- Revolving debt..................... 52,591 -- 52,591 -- -- Gunnison development............... 46,700 41,000 5,700 -- -- Investments in Deepwater Gateway L.L.C.(A)........................ -- -- -- -- -- Operating Leases................... 19,018 8,848 9,231 552 387 Redeemable stock in subsidiary..... 7,528 2,509 5,019 -- -- Canyon capital leases and other.... 3,788 1,435 1,967 386 -- -------- ------- ------- ------- -------- Total Cash Obligation.............. $301,023 $56,558 $94,601 $23,133 $126,731 ======== ======= ======= ======= ========
- --------------- (A) Excludes CDI guarantee of balloon payment due in 2008 on non-recourse project financing (estimated to be $22.5 million). In addition, in connection with our business strategy, we evaluate acquisition opportunities (including additional vessels as well as interest in offshore natural gas and oil properties). We believe 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 meet these obligations and achieve our planned growth. ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK The Company is currently exposed to market risk in two major areas: commodity prices and foreign currency. Because all of the Company's debt at December 31, 2002 was based on floating rates, changes in interest would, assuming all other things equal, have a minimal impact on the fair market value of the debt instruments. Assuming December 31, 2002 debt levels, every 100 basis points move in interest rates would result in $2.3 million of annualized interest expense or savings, as the case may be, to the Company. COMMODITY PRICE RISK The Company has utilized derivative financial instruments with respect to a portion of 2002 and 2003 oil and gas production to achieve a more predictable cash flow by reducing its exposure to price fluctuations. The Company does not enter into derivative or other financial instruments for trading purposes. As of December 31, 2002, the Company has the following volumes under derivative contracts related to its oil and gas producing activities:
INSTRUMENT AVERAGE MONTHLY WEIGHTED PRODUCTION PERIOD TYPE VOLUMES AVERAGE PRICE - ----------------- ---------- --------------- ------------- Crude Oil: January -- December 2003................ Swap 46 MBbl $26.50 January -- December 2003................ Swap 30 MBbl $26.82 Natural Gas: January -- March 2003................... Swap 800,000 MMBtu $ 4.21 April -- December 2003.................. Swap 400,000 MMBtu $ 4.02 April -- December 2003.................. Swap 200,000 MMBtu $ 4.21
Changes in NYMEX oil and gas strip prices would, assuming all other things being equal, cause the fair market value of these instruments to increase or decrease. 36

Subsequent to December 31, 2002, the Company entered into natural gas swaps for the period April through December 2003. The contracts cover 200,000 MMBtu per month at $4.97. FOREIGN CURRENCY EXCHANGE RATES Because we operate in various oil and gas exploration and production regions in the world, we conduct a portion of our business in currencies other than the U.S. dollar (primarily with respect to Well Ops (U.K.) Limited). The functional currency for Well Ops (U.K.) Limited is the applicable local currency. Although the revenues are denominated in the local currency, the effects of foreign currency fluctuations are partly mitigated because local expenses of such foreign operations also generally are denominated in the same currency. The impact of exchange rate fluctuations during the twelve months ended December 31, 2002 did not have a material effect on reported amounts of revenues or net income. Assets and liabilities of Well Ops (U.K.) Limited are translated using the exchange rates in effect at the balance sheet date, resulting in translation adjustments that are reflected in accumulated other comprehensive loss in the stockholders' equity section of our balance sheet. Approximately 12% of our net assets are impacted by changes in foreign currencies in relation to the U.S. dollar. We recorded a $2.5 million adjustment, net of taxes, to our equity account for the twelve months ended December 31, 2002 to reflect the net impact of the decline of the British Pound against the U.S. dollar. Canyon Offshore, the Company's ROV subsidiary, has operations in the United Kingdom and Southeast Asia sectors. Canyon conducts the majority of its affairs in these regions in U.S. dollars which it considers the functional currency. When currencies other than the U.S. dollar are to be paid or received the resulting gain or loss from translation is recognized in the statements of operations. These amounts for the year ended December 31, 2002 were not material to the Company's results of operations or cash flows. 37

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements based on our audit. The consolidated financial statements of Cal Dive International, Inc. as of December 31, 2001 and for each of the years in the two year period ended December 31, 2001 were audited by other auditors who have ceased operations. Those auditors expressed an unqualified opinion on those consolidated financial statements in their report dated February 18, 2002 before the reclassification adjustments and conforming disclosures described in Note 10. We conducted our audit in accordance with auditing standards generally accepted in the United States. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audit provides a reasonable basis for our opinion. In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial position of Cal Dive International, Inc. and Subsidiaries at December 31, 2002 and the consolidated results of their operations and their cash flows for the year then ended in conformity with accounting principles generally accepted in the United States. As discussed in Note 1 to the accompanying consolidated financial statements, the Company adopted Statement of Financial Accounting Standards No. 142, "Goodwill and Other Intangible Assets" in 2002. As described above, the consolidated financial statements of Cal Dive International, Inc. and Subsidiaries as of December 31, 2001 and 2000, and for the years then ended were audited by other auditors who have ceased operations. As described in Note 10, the consolidated financial statements as of and for the year ended December 31, 2001 have been revised. We audited the reclassification adjustments and conforming disclosures described in Note 10 applied to revise the 2001 financial statements. In our opinion, such reclassification adjustments and conforming disclosures are appropriate and have been properly applied. However, we were not engaged to audit, review or apply any procedures to the 2001 consolidated financial statements of the Company other than with respect to such reclassification adjustments and conforming disclosures and, accordingly, we do not express an opinion or any other form of assurance on the 2001 consolidated financial statements taken as a whole. /s/ ERNST & YOUNG LLP Houston, Texas February 17, 2003 39

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, is an energy services company specializing in subsea construction and well operation. CDI operates primarily in the Gulf of Mexico (Gulf), and recently in the North Sea, with services that cover the lifecycle of an offshore oil or gas field. CDI's current diversified fleet of 23 vessels and 21 remotely operated vehicles (ROVs) and trencher systems perform services that support drilling, well completion, intervention, construction and decommissioning projects involving pipelines, production platforms, risers and subsea production systems. The Company also has a significant investment in oil and gas properties and related production facilities as part of its Production Partnering business. CDI's customers include major and independent oil and gas producers, pipeline transmission companies and offshore engineering and construction firms. 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES PRINCIPLES OF CONSOLIDATION The accompanying consolidated financial statements include the accounts of the Company and its majority owned subsidiaries. All significant intercompany accounts and transactions have been eliminated. The Company accounts for its 50% interest in Deepwater Gateway L.L.C. using the equity method of accounting as the Company does not have voting or operational control of this entity. 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. On an ongoing basis the Company evaluates its estimates including those related to bad debts, investments, intangible assets and goodwill, property plant and equipment, income taxes, workers' insurance and contingent liabilities. The Company bases its estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results could differ from those estimates. GOODWILL AND INDEFINITE-LIVED INTANGIBLES In accordance with Statement of Financial Accounting Standards ("SFAS") No. 142, Goodwill and Indefinite-Lived Intangibles ("SFAS No. 142"), the Company tests for the impairment of goodwill and other intangible assets with indefinite lives on at least an annual basis. The Company's goodwill impairment test involves a comparison of the fair value of each of the Company's reporting units, as defined under SFAS No. 142, with its carrying amount. The Company's indefinite-lived asset impairment test involves a comparison of the fair value of the intangible and its carrying value. The fair value is determined using discounted cash flows and other market-related valuation models, such as earnings multiples and comparable asset market values. Prior to the adoption of SFAS No. 142, goodwill was amortized on a straight line basis over 25 years. In conjunction with the adoption of this statement, the Company has discontinued the amortization of goodwill. PROPERTY AND EQUIPMENT Property and equipment, both owned and under capital leases, are recorded at cost. Depreciation is provided primarily on the straight-line method over the estimated useful lives of the assets. 45

CAL DIVE INTERNATIONAL, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) All of the Company's interests in oil and gas properties are located offshore in United States waters. The Company follows the successful efforts method of accounting for its interests in oil and gas 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. Energy Resource Technology, Inc. ("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. The following is a summary of the components of property and equipment (dollars in thousands):

ESTIMATED USEFUL LIFE 2002 2001 ----------- -------- -------- Construction in progress............................. N/A $ 32,943 $221,916 Vessels.............................................. 15 to 30 465,158 103,929 Offshore leases and equipment........................ UOP 210,542 82,334 Machinery, equipment and leasehold improvements...... 5 18,235 15,563 -------- -------- Total property and equipment....................... $726,878 $423,742 ======== ========
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 were included in Construction in Progress as of December 31, 2001. Both of these vessels were placed in service during 2002 and are included in Vessels as of December 31, 2002. Construction in progress as of December 31, 2002 includes costs incurred relating to construction of the spar at Gunnison (see note 9). The Company capitalized interest totaling $4.4 million and $1.9 million during the years ended December 31, 2002 and 2001, respectively. During 2001, the Company acquired two additional DP marine construction vessels (the Mystic Viking and the Eclipse). The total cost of the two vessels acquired and related upgrades was approximately $40 million, the majority of which was expended and capitalized as of December 31, 2001. 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 $11,489,000, $8,501,000 and $4,343,000 for the years ended December 31, 2002, 2001 and 2000, respectively. In accordance with SFAS No. 144, Accounting for the Impairment or Disposal of Long-Lived Assets, long-lived assets, excluding goodwill and indefinite-lived intangibles, to be held and used by the Company are reviewed to determine whether any events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable. SFAS No. 144 modifies SFAS No. 121, Accounting for the Impairment or Disposal of Long-Lived Assets to be Disposed of. For long-lived assets to be held and used, the Company bases its evaluation on impairment indicators such as the nature of the assets, the future economic benefit of the assets, any historical or future profitability measurements and other external market conditions or factors that my be present. If such impairment indicators are present or other factors exist that indicate that the carrying amount of the asset may not be recoverable, the Company determines whether an impairment has occurred through the use of an undiscounted cash flows analysis of the asset at the lowest level for which identifiable cash flows exist. If an impairment has occurred, the Company recognizes a loss for the difference between the 46

CAL DIVE INTERNATIONAL, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) carrying amount and the fair value of the asset. The fair value of the asset is measured using quoted market prices or, in the absence of quoted market prices, is based on an estimate of discounted cash flows. Assets are classified as held for sale when the Company has a plan for disposal of certain assets and those assets meet the held for sale criteria of SFAS No. 144. FOREIGN CURRENCY The functional currency for the Company's foreign subsidiary Well Ops (U.K.) Limited is the applicable local currency (British Pound). Results of operations for this subsidiary are translated into U.S. dollars using average exchange rates during the period. Assets and liabilities of this foreign subsidiary are translated into U.S. dollars using the exchange rate in effect at the balance sheet date and the resulting translation adjustment, which was a gain of $2.5 million, net of taxes of $1.4 million, in 2002 is included as accumulated other comprehensive loss, as a component of shareholders' equity. All foreign currency transaction gains and losses are recognized currently in the statements of operations. These amounts for the year ended December 31, 2002 were not material to the Company's results of operations or cash flows. Canyon Offshore, the Company's ROV and robotics subsidiary, has operations in the United Kingdom and Southeast Asia sectors. Canyon conducts the majority of its affairs in these regions in U.S. dollars which it considers the functional currency. When currencies other than the U.S. dollar are to be paid or received the resulting gain or loss from translation is recognized in the statements of operations. These amounts for the year ended December 31, 2002 were not material to the Company's results of operations or cash flows. ACCOUNTING FOR PRICE RISK MANAGEMENT ACTIVITIES The Company's price risk management activities involve the use of derivative financial instruments to hedge the impact of market price risk exposures primarily related to our oil and gas production. Under SFAS No. 133, Accounting for Derivative Instruments and Hedging Activities, all derivatives are reflected in our balance sheet at their fair market value. Under SFAS No. 133 there are two types of hedging activities: hedges of cash flow exposure and hedges of fair value exposure. The Company engages primarily in cash flow hedges. Hedges of cash flow exposure are entered into to hedge a forecasted transaction or the variability of cash flows to be received or paid related to a recognized asset or liability. Changes in the derivative fair values that are designated as cash flow hedges are deferred to the extent that they are effective and are recorded as a component of accumulated other comprehensive income until the hedged transactions occur and are recognized in earnings. The ineffective portion of a cash flow hedge's change in value is recognized immediately in earnings in oil and gas production revenues. As required by SFAS No. 133, we formally document all relationships between hedging instruments and hedged items, as well as our risk management objectives, strategies for undertaking various hedge transactions and our methods for assessing and testing correlation and hedge ineffectiveness. All hedging instruments are linked to the hedged asset, liability, firm commitment or forecasted transaction. We also assess, both at the inception of the hedge and on an on-going basis, whether the derivatives that are used in our hedging transactions are highly effective in offsetting changes in cash flows of the hedged items. We discontinue hedge accounting prospectively if we determine that a derivative is no longer highly effective as a hedge. The market value of hedging instruments reflects our best estimate and is based upon exchange or over-the-counter quotations whenever they are available. Quoted valuations may not be available due to location differences or terms that extend beyond the period for which quotations are available. Where quotes are not available, we utilize other valuation techniques or models to estimate market values. These modeling techniques require us to make estimations of future prices, price correlation and market volatility and liquidity. Our actual results may differ from our estimates, and these differences can be positive or negative. 47

CAL DIVE INTERNATIONAL, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) During the second half of 2002, the Company entered into various cash flow hedging swap contracts to fix cash flows relating to a portion of the Company's oil and gas production. All of these qualified for hedge accounting and none extended beyond a year and a half. The aggregate fair value of the hedges was a liability of $4.1 million as of December 31, 2002. The Company recorded $2.6 million of loss, net of taxes of $1.4 million, in other comprehensive loss within shareholders' equity as these hedges were highly effective. As of December 31, 2002, the Company has the following volumes under derivative contracts related to its oil and gas producing activities:

INSTRUMENT AVERAGE WEIGHTED PRODUCTION PERIOD TYPE MONTHLY VOLUMES AVERAGE PRICE - ----------------- ---------- --------------- ------------- Crude Oil: January -- December 2003........................ Swap 46 MBbl $26.50 January -- December 2003........................ Swap 30 MBbl $26.82 Natural Gas: January -- March 2003........................... Swap 800,000 MMBtu $ 4.21 April -- December 2003.......................... Swap 400,000 MMBtu $ 4.02 April -- December 2003.......................... Swap 200,000 MMBtu $ 4.21
Subsequent to December 31, 2002, the Company entered into additional natural gas hedges for the period April through December 2003. The contracts cover 200,000 MMBtu per month at $4.97. In June 2002, CDI signed an agreement with Coflexip to acquire the Subsea Well Operations Business Unit for 44.8 million British pounds (which at the time equaled $67.5 million) which subsequently closed in July. CDI entered into a foreign currency forward contract to lock in the British pound to U.S. dollar exchange rate. Under SFAS No. 133, we accounted for this transaction with changes in its fair value reported in earnings. Accordingly, a $1.1 million gain was recorded in other income for the year ended December 31, 2002 as a result of the change in market value of the contract as of June 30, 2002. This contract settled in July 2002 for $1.1 million. 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. STOCK BASED COMPENSATION PLANS In December 2002, the Financial Accounting Standards Board ("FASB") issued SFAS No. 148, Accounting for Stock-Based Compensation Transition and Disclosure("SFAS No. 148") to provide alternative methods of transition for a voluntary change to the fair value based method of accounting for stock-based employee compensation. As permitted under SFAS No. 123, the Company continues to use the intrinsic value method of accounting established by Accounting Principles Board Opinion No. 25, Accounting for Stock Issued to Employees, to account for its stock-based compensation programs. Accordingly, no compensation expense is recognized when the exercise price of an employee stock option is equal to the Common Share market price on the grant date. If SFAS No. 123 had been used for the accounting of these plans, the Company's pro forma net income for 2002, 2001 and 2000 would have been $7.9 million, $25.9 million and $21.7 million, respectively, and the Company's pro forma diluted earnings per share would have been $0.22, 48

CAL DIVE INTERNATIONAL, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) $0.79 and $0.67, 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. For the purposes of pro forma disclosures, 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 5.0 percent in 2000, 4.5 percent in 2001 and 4.0 percent in 2002, and expected volatility to be 62 percent in 2000, 61 percent in 2001 and 59 percent in 2002. The fair value of shares issued under the Employee Stock Purchase Plan was based on the 15% discount received by the employees. The weighted average per share fair value of the options granted in 2002, 2001 and 2000 was $15.20, $14.47, and $8.05, respectively. The estimated fair value of the options is amortized to pro forma expense over the vesting period. 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, 2002 are expected to be billed and collected within one year. The Company records revenues from the sales of crude oil and natural gas when delivery to the customer has occurred and title has transferred. This occurs when production has been delivered to a pipeline or a barge lifting has occurred. The Company may have an interest with other producers in certain properties. In this case the Company used the entitlements method to account for sales of production. Under the entitlements method the Company may receive more or less than its entitled share of production. If the Company receives more than its entitled share of production, the imbalance is treated as a liability. If the Company receives less than its entitled share, the imbalance is recorded as an asset. 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 allowed under the terms of the related contract but 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 primarily 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: 2002 -- BP Trinidad & Tobago LLC (11%); Horizon Offshore, Inc. (10%); 2001 -- Horizon Offshore, Inc. (18%), Enron Corp. (10%); and 2000 -- Enron Corp. (13%). 49

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 and 2002 the Company also provided dynamically positioned vessels to support Horizon projects for Pemex in Mexican waters of the Gulf of Mexico. INCOME TAXES Deferred income taxes are based on the differences between financial reporting and the tax bases of assets and liabilities 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. Income taxes have been provided based upon the tax laws and rates in the countries in which operations are conducted and income is earned. A valuation allowance for deferred tax assets is recorded when it is more likely than not that some or all of the benefit from the deferred tax asset will not be realized. 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, 2002, 2001 and 2000, drydock amortization expense was $4.9 million, $3.1 million and $2.2 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). 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. The Company had $2.5 million of restricted cash as of December 31, 2002 representing amounts securing a performance bond which management believes will be released during 2003. During the years ended December 31, 2002, 2001 and 2000, the Company made cash payments for interest charges, net of interest capitalized, of $811,000, $662,000 and $-0-, respectively, and made cash payments for federal income taxes of approximately $-0-, $-0- and $1,800,000 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. NEW REPORTING REQUIREMENTS In July 2001, the FASB released SFAS No. 143, Accounting for Asset Retirement Obligations, which is required to be adopted no later than January 1, 2003. SFAS 143 addresses the financial accounting and reporting obligations and retirement costs related to the retirement of tangible long-lived assets. Among other things, SFAS 143 will require oil and gas companies to reflect decommissioning liabilities on the face of the balance sheet at fair market value on a discounted basis. Historically, ERT has reflected this liability on the balance sheet on an undiscounted basis. The Company will adopt this standard, as required, effective January 1, 2003. Management currently believes adoption of this standard will result in a cumulative effect adjustment in the first quarter of 2003 of between $0.01 and $0.03 per share and adjustments to certain balance sheet accounts including a decrease in Decommissioning Liabilities of approximately $30 million due to discounting. 50

CAL DIVE INTERNATIONAL, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) In November 2002, FASB interpretation ("FIN") No. 45, Guarantor's Accounting and Disclosure Requirements for Guarantees, Including Indirect Guarantees of Indebtedness of Others ("FIN No. 45") was issued. FIN No. 45 requires a guarantor to recognize at the inception of a guarantee a liability for the fair value of the obligation undertaken in issuing the guarantee. FIN No. 45 also expands the disclosures required to be made by a guarantor about its obligations under certain guarantees that it has issued. Initial recognition and measurement provisions of FIN No. 45 are applicable on a prospective basis to guarantees issued or modified. The disclosure requirements are effective immediately. Adoption of FIN No. 45 did not have a material effect on CDI's consolidated financial statements. In January 2003, FIN No. 46, Consolidation of Variable Interest Entities was issued. FIN No. 46 requires that companies that control another entity through interests other than voting interests should consolidate the controlled entity. FIN No. 46 applies immediately to variable interest entities created after January 31, 2003, and applies in the first interim period beginning after June 15, 2003 to variable interest entities created before February 1, 2003. The related disclosure requirements are effective immediately. The Company does not believe that the adoption of this interpretation will have a material impact on its consolidated financial statements. 3. OFFSHORE PROPERTY TRANSACTIONS In August 2002 ERT, a wholly owned subsidiary of Cal Dive International, Inc. acquired the 74.8% working interest of Shell Exploration & Production Company in the South Marsh Island 130 (SMI 130) field (Shell acquisition). ERT paid $10.3 million in cash and assumed Shell's pro-rata share of the related decommissioning liability. SMI 130 consists of two blocks, located in approximately 215 feet of water, with approximately 155 wells on five 8-pile platforms. Unaudited pro forma combined operating results of CDI and the Shell acquisition for the twelve months ended December 31, 2002 and 2001, respectively are summarized as follows (in thousands, except per share data):

2002 2001 -------- -------- (UNAUDITED) Net revenues................................................ $321,186 $259,762 Income before taxes......................................... 23,690 54,892 Net income.................................................. 15,399 35,828 Earnings per share: Basic..................................................... $ 0.43 $ 1.10 Diluted................................................... 0.43 1.08
In August 2002, ERT also completed the purchase of seven Gulf of Mexico fields from Amerada Hess (including its 25% ownership position in SMI 130) for $9.3 million in cash and assumption of Amerada Hess's pro-rata share of the related decommissioning liability. As a result, ERT took over as operator with an effective 100% working interest in that field. In June 2002, ERT acquired a package of offshore properties from Williams Exploration and Production. ERT paid $4.9 million and assumed the pro-rata share of the abandonment obligation for the acquired interests. The blocks purchased represent an average 30% net working interest in 26 Gulf of Mexico leases. In April 2002, ERT acquired a 100% interest in East Cameron Block 374, including existing wells, equipment and improvements. Terms included a cash payment of approximately $3 million to reimburse the owners for the inception-to-date cost of the subsea wellhead and umbilical, and an overriding royalty interest in future production. Cal Dive completed the temporarily abandoned number one well and performed a subsea tie-back to a host platform. The cost of completion and tie-back was approximately $7 million, with first production occurring in August 2002. 51

CAL DIVE INTERNATIONAL, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) 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 4). In the first quarter of 2000, ERT acquired interests in six offshore blocks with 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 the prorated share of the abandonment obligation for the acquired interests, and entered into a two-year contract to manage certain properties. Additionally, in April 2000, ERT acquired a 20% interest in Gunnison. See further discussion in footnote 4. In connection with 2002, 2001 and 2000 offshore property acquisitions, ERT assumed net abandonment liabilities estimated at approximately $63.6 million, $3.1 million and $4.2 million 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 $9.2 million, $15.2 million and $11.7 million for the years ended 2002, 2001 and 2000, 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 had no impact for the year ended December 31, 2002 and added two cents and four cents to diluted earnings per share for the years ending December 31, 2001 and 2000, 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 oil and gas properties. 4. 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 of approximately $20 million was provided by an investment partnership (OKCD Investments, Ltd.), the investors of which are CDI senior management, in exchange for an overriding royalty interest of 25% of CDI's 20% working interest. CDI provided no guarantees to the investment partnership. 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. With the sanctioning of a commercial discovery, the Company is funding ongoing development and production costs. Cal Dive's share of such project development costs is estimated in a range of $100 million to $110 million ($63.3 million of which had been incurred by December 31, 2002) with over half of that for construction of the spar. See footnote 9 for discussion of financing relating to the spar construction. 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 52

CAL DIVE INTERNATIONAL, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) with the guidelines and at least as favorable to the Company and ERT as could have been obtained from the third parties. During 2002 and 2001, the Company was paid fees of $200,000 and $500,000, respectively, by Ocean Energy, Inc. ("Ocean"), an oil and gas industry customer of subsea services. A member of the Company's board of directors, is a member of senior management of Ocean. 5. ACQUISITION OF BUSINESSES CANYON OFFSHORE, INC. In January 2002, CDI purchased Canyon, a supplier of remotely operated vehicles (ROVs) and robotics to the offshore construction and telecommunications industries. CDI purchased Canyon for cash of $52.8 million, the assumption of $9.0 million of Canyon debt (offset by $3.1 million of cash acquired), 181,000 shares of CDI common stock valued at $4.3 million (143,000 shares of which we purchased as treasury shares during the fourth quarter of 2001) and a commitment to purchase the redeemable stock in Canyon at a price to be determined by Canyon's performance during the years 2002 through 2004 from continuing employees at a minimum purchase price of $13.53 per share (or $7.5 million). As they are employees, amounts paid, if any, in excess of the $13.53 per share will be recorded as compensation expense. No such expense was recorded in 2002. These remaining shares have been classified as redeemable stock in subsidiary in the accompanying balance sheet and will be adjusted to their estimated redemption value at each reporting period based on Canyon's performance. The acquisition was accounted for as a purchase with the acquisition price allocated to the assets acquired and liabilities assumed based upon their estimated fair values, with the excess being recorded as goodwill. The allocation of the $70.5 million purchase price was as follows: ROVs and equipment ($22.9 million); net working capital assumed ($4.0 million) and goodwill ($43.6 million). The results of Canyon are included in the accompanying statements of operations since the date of the purchase, January 2, 2002. WELL OPS (U.K.) LIMITED In July 2002, CDI purchased the subsea well operations business unit of CSO Ltd., a wholly owned subsidiary of Technip-Coflexip, for approximately $72.0 million ($68.6 million cash and $3.4 million deferred tax liability assumption). Well Ops (U.K.) Limited performs life of field well operations and marine construction tasks primarily in the North Sea. The assets purchased include the Seawell (a 368-foot DPDSV capable of supporting manned diving, ROVs and well operations). The acquisition was accounted for as a business purchase with the acquisition price allocated to the assets acquired and liabilities assumed based upon their estimated fair values, with the excess being recorded as goodwill. During the fourth quarter of 2002 the Company completed its purchase price allocation, including obtaining an appraisal of the Seawell,resulting in $50 million allocated to this vessel $1.5 million allocated to patented technology (to be amortized over 20 years) and goodwill of approximately $20.6 million as of December 31, 2002. The results of Well Ops (U.K.) are included in the accompanying statements of operations since the date of the purchase, July 1, 2002. PROFESSIONAL DIVERS OF NEW ORLEANS, INC. (PDNO) 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 a 165-foot four-point moored DSV, 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 goodwill. Total goodwill relating to shallow water diving company acquisitions (i.e., PDNO and Aquatica) was $15 million as of December 31, 2002. 53

CAL DIVE INTERNATIONAL, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) The 2002 and 2001 acquisitions presented above are not material individually or in the aggregate with same year acquisitions, therefore pro forma information is not presented. 6. EQUITY INVESTMENT IN DEEPWATER GATEWAY L.L.C. In June 2002 CDI, along with El Paso Energy Partners, formed Deepwater Gateway L.L.C. (a 50/50 venture) to design, construct, install, own and operate a tension leg platform ("TLP") production hub primarily for Anadarko Petroleum Corporation's Marco Polo field discovery in the Deepwater Gulf of Mexico. CDI's share of the construction costs is estimated to be approximately $110 million. In August 2002 the Company, along with El Paso, completed a non-recourse project financing for this venture, terms of which include a minimum CDI equity investment of $33 million, all of which had been paid as of December 31, 2002. This is recorded as Investment in Deepwater Gateway L.L.C. in the accompanying consolidated balance sheet. Terms of the financing also require CDI to guarantee a balloon payment due at the end of the financing term in 2008 (estimated to be $22.5 million). The Company has not recorded any liability for this guarantee as management believes it is unlikely the Company will be required to pay the balloon payment. 7. GOODWILL In June 2001, the FASB issued SFAS No. 142, which provides for the non-amortization of goodwill and other intangible assets with indefinite lives and requires that such assets be tested for impairment at least on an annual basis. The impact of adopting SFAS No. 142 would have been immaterial to the Company's results of operations for the years ended December 31, 2001 and 2000, respectively. The Company adopted SFAS No. 142 effective January 1, 2002 and has applied the non-amortization provision. During the second quarter of 2002, the Company completed the transitional goodwill impairment test prescribed in SFAS No. 142 with respect to existing goodwill at the date of adoption. In addition, the Company completed its annual goodwill impairment test as of November 1, 2002. The Company's goodwill impairment test involves a comparison of the fair value of each of the Company's reporting units, as defined under SFAS No. 142, with its carrying amount. All of the Company's goodwill as of December 31, 2002 and 2001 related to its subsea and salvage segment. The fair value is determined using discounted cash flows and other market-related valuation models. As both calculations indicated that the fair value of each reporting unit exceeded its carrying amount, none of the Company's goodwill was impaired. The Company will continue to test its goodwill annually on a consistent measurement date unless events occur or circumstances change between annual tests that would more likely than not reduce the fair value of a reporting unit below its carrying amount. 8. ACCRUED LIABILITIES Accrued liabilities consisted of the following as of December 31, 2002 and 2001 (in thousands):

2002 2001 ------- ------- Accrued payroll and related benefits........................ $ 6,874 $ 6,880 Workers' compensation claims................................ 1,724 1,537 Workers' compensation claims to be reimbursed............... 5,534 6,276 Royalties payable........................................... 3,238 3,207 Hedging liability........................................... 4,064 -- Other....................................................... 13,356 3,111 ------- ------- Total accrued liabilities................................. $34,790 $21,011 ======= =======

CAL DIVE INTERNATIONAL, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) 9. 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. To date the Company has drawn $143.5 million on this facility, which approximates the maximum of qualified expenditures. The MARAD Debt is payable in equal semi-annual installments beginning in August 2002 and maturing 25 years from such date. It is collateralized by the Q4000, with CDI guaranteeing 50% of the debt, and bears interest at a rate which currently floats at a rate approximating AAA Commercial Paper yields plus 20 basis points (approximately 2% as of December 31, 2002). For a period up to ten years from delivery of the vessel in April 2002, 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, working capital and debt-to-equity requirements. As of December 31, 2002 the Company was in compliance with these covenants. The Company has a revolving credit facility ("Revolver") which was increased from $40 million to $70 million during 2002 and the term extended for 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 (approximately 4.2% as of December 31, 2002) and, among other restrictions, includes three financial covenants (cash flow leverage, minimum interest coverage and fixed charge coverage). As of December 31, 2002, the Company had drawn $52.6 million under this revolving credit facility and was in compliance with these covenants with the exception of the cash flow leverage covenant, for which the Company obtained a waiver. In November 2001, ERT entered into a five-year lease transaction with an entity owned by a third party to fund CDI's portion of the construction costs ($67 million) of the spar for the Gunnison field. As of December 31, 2001 and June 30, 2002, the entity had drawn down $5.6 million and $22.8 million, respectively, 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. In August 2002, CDI acquired 100% of the equity of the entity and converted the notes into a term loan ("Gunnison Term Loan"). The total commitment of the loan was reduced to $35 million and will be payable in quarterly installments of $1.75 million for three years after delivery of the spar with the remaining $15.75 million due at the end of the three years. The facility bears interest at LIBOR plus 225-300 basis points depending on CDI leverage ratios (approximately 4.4% as of December 31, 2002) 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, 2002 with the exception of the cash flow leverage covenant, for which the Company obtained a waiver. The debt ($29.3 million at December 31, 2002) and related asset have been reflected on CDI's balance sheet beginning in the third quarter of 2002. The purchase price was allocated entirely to construction in progress as the purchase price approximated the fair value of the spar. 55

10. INCOME TAXES CDI and its subsidiaries, including acquired companies from their respective dates of acquisition, file a consolidated U.S. federal income tax return. The Company conducts its international operations in a number of locations that have varying laws and regulations with regard to taxes. Management believes that adequate provisions have been made for all taxes that will ultimately be payable. $2.5 million of the Company's $19.0 million pre-tax income was derived from foreign operations. 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:
2002 2001 2000 ---- ---- ---- Statutory rate.............................................. 35% 35% 35% Foreign provision........................................... 4 -- -- Foreign tax credit..........................................

The detail of deferred tax balances as of December 31, 2001 described above contain reclassification adjustments totaling $21.2 million and conforming disclosures to provide a detail of deferred tax assets that were previously offset against deferred tax liabilities. The Company's consolidated balance sheet as of December 31, 2001 has been adjusted to conform with the above presentation. CDI effectively paid no federal income taxes in 2002 and 2001 due primarily 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. The Company has provided additional taxes for the anticipated repatriation of earnings of its foreign subsidiaries. At December 31, 2002, the Company had $81.1 million of net operating losses. Loss carryforwards, if not utilized, will expire at various dates from 2019 through 2022. 11. COMMITMENTS AND CONTINGENCIES: LEASE COMMITMENTS During 1999, CDI acquired an interest in Cal Dive Aker CAHT I, L.L.C. (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. 57

CAL DIVE INTERNATIONAL, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) The Company leases several facilities, ROVs and a vessel under noncancelable operating leases, with the more significant leases expiring in the years 2004 and 2005. Future minimum rentals under these leases are $19,018,000 at December 31, 2002 with $8,848,000 due in 2003, $7,033,000 in 2004, $2,198,000 in 2005, $276,000 in 2006, $276,000 in 2007 and $387,000 thereafter. Total rental expense under these operating leases was $6,885,000, $779,000 and $721,000 for the years ended December 31, 2002, 2001 and 2000, respectively. 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 $100,000 per occurrence plus a $1 million annual aggregate. In addition to the liability policies named above, the Company carries various layers of Umbrella Liability for total limits of $200,000,000 excess of primary for all vessels. The Company's self insured retention on its medical and health benefits program for employees is $100,000 per claim. In June 2000, the DP DSV Balmoral Sea caught fire while dockside in New Orleans, Louisiana 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 $5,534,000 and $6,276,000 as of December 31, 2002 and 2001, respectively. See related accrued liabilities at footnote 8. The Company has not incurred any significant losses as a result of claims denied by its insurance carriers. LITIGATION AND CLAIMS 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. During 2002, the Company engaged in a large construction project and, in late September, supports engineered by a subcontractor failed resulting in over a month of downtime for two of CDI's vessels. Management believes that under the terms of the contract the Company is entitled to the contractual stand-by rate for the vessels during their downtime. The customer is currently disputing these invoices along with certain other change orders. Of the amounts billed by CDI for this project, $12.1 million had not been collected as of February 18, 2003. Due to the size of the dispute, inherent uncertainties with respect to an arbitration and relationship issues with the customer, CDI provided a reserve in the fourth quarter of 2002 resulting in a loss for the Company on the project as a whole. In another lengthy 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 had responded alleging EEX Corporation breached various provisions of the same contracts. EEX's acquisition by Newfield during the fourth quarter 2002 enabled CDI to enter meaningful settlement discussions prior to the trial date, 58

CAL DIVE INTERNATIONAL, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) which was set for February 2003. This resulted in a settlement including CDI making a cash payment, subsequent to yearend, and agreeing to provide work credits for its services over the next three years. The total value of the settlement was recorded in the Company's statement of operations for the year ended December 31, 2002. This settlement combined with the reserves on the project discussed above resulted in approximately $10 million of pre-tax charges recorded in the accompanying statement of operations. In 1998, one of our subsidiaries entered into a subcontract with Seacore Marine Contractors Limited ("Seacore") to provide the Sea Sorceress to a Coflexip subsidiary in Canada ("Coflexip"). Due to difficulties with respect to the sea states and soil conditions the contract was terminated and an arbitration to recover damages was commenced. A preliminary liability finding has been made by the arbitrator against Seacore and in favor of the Coflexip subsidiary. We were not a party to this arbitration proceeding. Seacore and Coflexip settled this matter prior to the conclusion of the arbitration proceeding with Seacore paying Coflexip $6.95 million CDN. Seacore has now made demand on Cal Dive Offshore Ltd. ("CDO"), a subsidiary of Cal Dive, for one-half of this amount. Because only one of the grounds in the preliminary findings by the arbitrator is applicable to CDO, and because CDO holds substantial counterclaims against Seacore, management believes that in the event Seacore continues to seek contribution from our subsidiary, which would require another arbitration, it is anticipated that our subsidiary's exposure, if any, should be less than $500,000. Although the above discussed matters have the potential of significant additional liability, the Company believes that the outcome of all such matters and proceedings will not have a material adverse effect on its consolidated financial position, results of operations or cash flows. 12. 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 $811,000, $595,000 and $423,000 for the years ended December 31, 2002, 2001 and 2000, 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 2002, 2001 and 2000 resulting in a total of 105,000, 180,000 and 115,000 options being granted during 2002, 2001 and 2000, respectively (which includes bonuses earned under the annual incentive compensation program in 2001 and 2000). 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% 59

CAL DIVE INTERNATIONAL, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) 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 44,158, 38,849 and 25,391 shares of common stock were purchased in the open market at a weighted average share price of $21.86, $22.22 and $21.55 during 2002, 2001 and 2000, respectively. All of the options outstanding at December 31, 2002, have exercise prices as follows: 127,191 shares at $18.00, 111,596 at $18.06, 129,000 shares at $19.63, 100,000 shares at $21.38, 412,000 shares at $21.83, 283,004 shares at $21.88, 120,000 shares at $24.00, 80,000 shares at $26.75 and 627,955 shares ranging from $3.95 to $23.72 and a weighted average remaining contractual life of 6.11 years.

13. SHAREHOLDERS' EQUITY 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 and 5,000,000 shares of preferred stock in one or more series. In May 2002 CDI sold 3.4 million shares of primary common stock for $23.16 per share, along with 517,000 additional shares to cover over-allotments. 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 receiving net proceeds of $12.1 million. 60

ESTIMATED QUANTITIES OF PROVED OIL AND GAS RESERVES Proved 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, 2002, excluding Gunnison, have been reviewed by Miller and Lents, 62

CAL DIVE INTERNATIONAL, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) Ltd., independent petroleum engineers. Since the Company does not own a license to the geophysical data, reserves attributable to Gunnison (which total 47% of the proved reserves as of December 31, 2002) have been determined based on information provided by the operator. These reserve estimates were reviewed by our engineers, including an assessment of the operator's assumptions and their engineering, geologic and evaluation principles and techniques. All of the Company's reserves are located in the United States. Proved reserves cannot be measured exactly because the estimation of 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, 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. As of December 31, 2002 6,375,000 Bbls of oil and 51,807,000 Mcf of gas were undeveloped, 82% of which is attributable to Gunnison.

QUARTERLY FINANCIAL INFORMATION (UNAUDITED) The offshore marine construction industry in the Gulf of Mexico is highly seasonal as a result of weather conditions and the timing of capital expenditures by the oil and gas companies. Historically, a substantial portion of the Company's services has been performed during the summer and fall months. As a result, historically a disproportionate portion of the Company's revenues and net income is earned during such period. The following is a summary of consolidated quarterly financial information for 2002 and 2001.

18. SUBSEQUENT EVENTS SALE OF CONVERTIBLE PREFERRED STOCK On January 8, 2003, CDI completed the private placement of $25 million of a newly designated class of cumulative convertible preferred stock (Series A-1 Cumulative Convertible Preferred Stock, par value $0.01 per share) that is convertible into 833,334 shares of Cal Dive common stock at $30 per share. The preferred stock was issued to a private investment firm. The preferred stock holder has the right to purchase as much as $30 million in additional preferred stock for a period of two years beginning in July, 2003. The conversion price of the additional preferred stock will equal 125% of the then prevailing price of Cal Dive common stock, subject to a minimum conversion price of $30 per common share. 65

CAL DIVE INTERNATIONAL, INC. AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED) The preferred stock will have a minimum annual dividend rate of 4%, subject to adjustment, payable in cash or common shares at Cal Dive's option. After the second anniversary, the holder may redeem the value of its original investments in the preferred shares to be settled in common stock or cash at the discretion of the Company. Under certain conditions, the holder could redeem its investment prior to the second anniversary. The proceeds received from the sale of this stock, net of transaction costs, will be classified outside of shareholders' equity on the balance sheet below total liabilities. The transaction costs will be accreted through the statement of operations over two years. Prior to the conversion, shares will be included in the Company's fully diluted earnings per share under the if converted method based on the Company's average common share price during the applicable period. Subsequent to year-end, the Company filed a registration statement registering approximately 7.5 million shares of common stock relating to this transaction, the maximum potential total number of shares of common stock redeemable under certain circumstances, subject to the Company's ability to redeem with cash, under the terms of the agreement. 66

The Borrower may permanently reduce the Aggregate Commitment in whole, or in part ratably among the Lenders in integral multiples of $1,000,000, upon at least five Business Days' written notice to the Agent, which notice shall specify the amount of any such reduction, provided, however, that the amount of the Aggregate Commitment may not be reduced below the aggregate principal amount of the outstanding Advances. All accrued commitment fees shall be payable on the effective date of any termination of the obligations of the Lenders to make Loans hereunder. 2.6. Agency Fee. The Borrower will pay the Agency Fee as and when due from time to time pursuant to the Fee Letter. 2.7. Minimum Amount of Each Advance. Each Eurodollar Advance shall be in the minimum amount of $1,000,000 (and in multiples of $100,000 if in excess thereof), and each 24

Floating Rate Advance shall be in the minimum amount of $1,000,000 (and in multiples of $100,000 if in excess thereof), provided, however, that the final Advance may be in the amount of the unused Aggregate Commitment. 2.8. Optional Principal Payments. The Borrower may from time to time pay, without penalty or premium, all outstanding Floating Rate Advances, or, in a minimum aggregate amount of $1,000,000 or any integral multiple of $100,000 in excess thereof, any portion of the outstanding Floating Rate Advances upon two Business Days' prior notice to the Agent. The Borrower may from time to time pay, subject to the payment of any funding indemnification amounts required by Section 3.4 but without penalty or premium, all outstanding Eurodollar Advances, or, in a minimum aggregate amount of $1,000,000 or any integral multiple of $100,000 in excess thereof, any portion of the outstanding Eurodollar Advances upon three Business Days' prior notice to the Agent. Principal payments made after the Funding Period Termination Date shall be applied to the principal installments payable under Section 2.2 in the inverse order of maturity. No principal prepayments may be reborrowed hereunder. 2.9. Method of Selecting Types and Interest Periods for New Advances. The Borrower shall select the Type of Advance and, in the case of each Eurodollar Advance, the Interest Period applicable thereto from time to time. The Borrower shall give the Agent irrevocable notice (a "Borrowing Notice") not later than 10:00 a.m. (Chicago time) at least one Business Day before the Borrowing Date of each Floating Rate Advance and three Business Days before the Borrowing Date for each Eurodollar Advance, substantially in the form of Exhibit H, specifying: (i) the Borrowing Date, which shall be a Business Day, of such Advance, (ii) the aggregate amount of such Advance, (iii) the Type of Advance selected, and (iv) in the case of each Eurodollar Advance, the Interest Period applicable thereto. Not later than noon (Chicago time) on each Borrowing Date, each Lender shall make available its Loan or Loans in funds immediately available in Chicago to the Agent at its address specified pursuant to Article XIII. The Agent will make the funds so received from the Lenders available to the Borrower at the Agent's aforesaid address. 2.10. Conversion and Continuation of Outstanding Advances. Floating Rate Advances shall continue as Floating Rate Advances unless and until such Floating Rate Advances are converted into Eurodollar Advances pursuant to this Section 2.10 or are repaid in accordance with Section 2.7 or Section 2.8. Each Eurodollar Advance shall continue as a Eurodollar Advance until the end of the then applicable Interest Period therefor, at which time such Eurodollar Advance shall be automatically converted into a Floating Rate Advance unless (x) such Eurodollar Advance is or was repaid in accordance with Section 2.7 or Section 2.8 or (y) the Borrower shall have given the Agent a Conversion/Continuation Notice (as defined below) requesting that, at the end of such Interest Period, such Eurodollar Advance continue as a Eurodollar Advance for the same or another Interest Period. Subject to the terms of Section 2.6, the Borrower may elect from time to time to convert all or any part of a Floating Rate Advance 25

into a Eurodollar Advance. The Borrower shall give the Agent irrevocable notice (a "Conversion/Continuation Notice") of each conversion of a Floating Rate Advance into a Eurodollar Advance or continuation of a Eurodollar Advance not later than 10:00 a.m. (Chicago time) at least three Business Days prior to the date of the requested conversion or continuation, specifying: (i) the requested date, which shall be a Business Day, of such conversion or continuation, (ii) the aggregate amount and Type of the Advance which is to be converted or continued, and (iii) the amount of such Advance which is to be converted into or continued as a Eurodollar Advance and the duration of the Interest Period applicable thereto. There shall be only one (1) Eurodollar Advance at any one time outstanding. 2.11. Changes in Interest Rate, etc. Each Floating Rate Advance shall bear interest on the outstanding principal amount thereof, for each day from and including the date such Advance is made or is automatically converted from a Eurodollar Advance into a Floating Rate Advance pursuant to Section 2.9, to but excluding the date it is paid or is converted into a Eurodollar Advance pursuant to Section 2.9 hereof, at a rate per annum equal to the Floating Rate for such day. Changes in the rate of interest on that portion of any Advance maintained as a Floating Rate Advance will take effect simultaneously with each change in the Alternate Base Rate. Each Eurodollar Advance shall bear interest on the outstanding principal amount thereof from and including the first day of the Interest Period applicable thereto to (but not including) the last day of such Interest Period at the interest rate determined by the Agent as applicable to such Eurodollar Advance based upon the Borrower's selections under Sections 2.8 and 2.9 and otherwise in accordance with the terms hereof. No Interest Period may end after the Facility Termination Date. The Borrower shall select Interest Periods so that it is not necessary to repay any portion of a Eurodollar Advance prior to the last day of the applicable Interest Period in order to make a mandatory repayment required pursuant to Section 2.2. 2.12. Rates Applicable After Default. Notwithstanding anything to the contrary contained in Section 2.8, 2.9 or 2.10, during the continuance of a Default or Unmatured Default the Required Lenders may, at their option, by notice to the Borrower (which notice may be revoked at the option of the Required Lenders notwithstanding any provision of Section 8.2 requiring unanimous consent of the Lenders to changes in interest rates), declare that no Advance may be made as, converted into or continued as a Eurodollar Advance. During the continuance of a Default the Required Lenders may, at their option, by notice to the Borrower (which notice may be revoked at the option of the Required Lenders notwithstanding any provision of Section 8.2 requiring unanimous consent of the Lenders to changes in interest rates), declare that (i) each Eurodollar Advance shall bear interest for the remainder of the applicable Interest Period at the rate otherwise applicable to such Interest Period plus 2% per annum and (ii) each Floating Rate Advance shall bear interest at a rate per annum equal to the Floating Rate in effect from time to time plus 2% per annum, provided that, during the continuance of a Default 26

under Section 7.6 or 7.7, the interest rates set forth in clauses (i) and (ii) above shall be applicable to all Advances without any election or action on the part of the Agent or any Lender. 2.13. Method of Payment. All payments of the Obligations hereunder shall be made, without setoff, deduction, or counterclaim, in immediately available funds to the Agent at the Agent's address specified pursuant to Article XIII, or at any other Lending Installation of the Agent specified in writing by the Agent to the Borrower, by noon (local time) on the date when due and shall be applied ratably by the Agent among the Lenders. Each payment delivered to the Agent for the account of any Lender shall be delivered promptly by the Agent to such Lender in the same type of funds that the Agent received at its address specified pursuant to Article XIII or at any Lending Installation specified in a notice received by the Agent from such Lender. The Agent is hereby authorized to charge the account of the Borrower maintained with Bank One for each payment of principal, interest and fees as it becomes due hereunder. 2.14. Noteless Agreement; Evidence of Indebtedness. (i) Each Lender shall maintain in accordance with its usual practice an account or accounts evidencing the indebtedness of the Borrower to such Lender resulting from each Loan made by such Lender from time to time, including the amounts of principal and interest payable and paid to such Lender from time to time hereunder. (ii) The Agent shall also maintain accounts in which it will record (a) the amount of each Loan made hereunder, the Type thereof and the Interest Period with respect thereto, (b) the amount of any principal or interest due and payable or to become due and payable from the Borrower to each Lender hereunder and (c) the amount of any sum received by the Agent hereunder from the Borrower and each Lender's share thereof. (iii) The entries maintained in the accounts maintained pursuant to paragraphs (i) and (ii) above shall be prima facie evidence of the existence and amounts of the Obligations therein recorded; provided, however, that the failure of the Agent or any Lender to maintain such accounts or any error therein shall not in any manner affect the obligation of the Borrower to repay the Obligations in accordance with their terms. (iv) Any Lender may request that its Loans be evidenced by a promissory note in substantially the form of Exhibit E (a "Note"). In such event, the Borrower shall prepare, execute and deliver to such Lender such Note payable to the order of such Lender. Thereafter, the Loans evidenced by such Note and interest thereon shall at all times (prior to any assignment pursuant to Section 12.3) be represented by one or more Notes payable to the order of the payee named therein, except to the extent that any such Lender subsequently returns any such Note for cancellation and requests that such Loans once again be evidenced as described in paragraphs (i) and (ii) above. 2.15. Telephonic Notices. The Borrower hereby authorizes the Lenders and the Agent to extend, convert or continue Advances, effect selections of Types of Advances and to transfer funds based on telephonic notices made by any person or persons the Agent or any Lender in 27

good faith believes to be acting on behalf of the Borrower, it being understood that the foregoing authorization is specifically intended to allow Borrowing Notices and Conversion/Continuation Notices to be given telephonically. The Borrower agrees to deliver promptly to the Agent a written confirmation, if such confirmation is requested by the Agent or any Lender, of each telephonic notice signed by an Authorized Officer. If the written confirmation differs in any material respect from the action taken by the Agent and the Lenders, the records of the Agent and the Lenders shall govern absent manifest error. 2.16. Interest Payment Dates; Interest and Fee Basis. Interest accrued on each Floating Rate Advance shall be payable on each Payment Date, commencing with the first such date to occur after the date hereof, on any date on which the Floating Rate Advance is prepaid, whether due to acceleration or otherwise, and at maturity. Interest accrued on that portion of the outstanding principal amount of any Floating Rate Advance converted into a Eurodollar Advance on a day other than a Payment Date shall be payable on the date of conversion. Interest accrued on each Eurodollar Advance shall be payable on the last day of its applicable Interest Period, on any date on which the Eurodollar Advance is prepaid, whether by acceleration or otherwise, and at maturity. Interest accrued on each Eurodollar Advance having an Interest Period longer than three months shall also be payable on the last day of each three-month interval during such Interest Period. Interest and commitment fees shall be calculated for actual days elapsed on the basis of a 360-day year. Interest shall be payable for the day an Advance is made but not for the day of any payment on the amount paid if payment is received prior to noon (local time) at the place of payment. If any payment of principal of or interest on an Advance shall become due on a day which is not a Business Day, such payment shall be made on the next succeeding Business Day and, in the case of a principal payment, such extension of time shall be included in computing interest in connection with such payment. 2.17. Notification of Advances, Interest Rates, Prepayments and Commitment Reductions. Promptly after receipt thereof, the Agent will notify each Lender of the contents of each Aggregate Commitment reduction notice, Borrowing Notice, Conversion/Continuation Notice, and repayment notice received by it hereunder. The Agent will notify each Lender of the interest rate applicable to each Eurodollar Advance promptly upon determination of such interest rate and will give each Lender prompt notice of each change in the Alternate Base Rate. 2.18. Lending Installations. Each Lender may book its Loans at any Lending Installation selected by such Lender and may change its Lending Installation from time to time. All terms of this Agreement shall apply to any such Lending Installation and the Loans and any Notes issued hereunder shall be deemed held by each Lender for the benefit of any such Lending Installation. Each Lender may, by written notice to the Agent and the Borrower in accordance with Article XIII, designate replacement or additional Lending Installations through which Loans will be made by it and for whose account Loan payments are to be made. 2.19. Non-Receipt of Funds by the Agent. Unless the Borrower or a Lender, as the case may be, notifies the Agent prior to the date on which it is scheduled to make payment to the Agent of (i) in the case of a Lender, the proceeds of a Loan or (ii) in the case of the Borrower, a payment of principal, interest or fees to the Agent for the account of the Lenders, that it does not intend to make such payment, the Agent may assume that such payment has been made. The Agent may, but shall not be obligated to, make the amount of such payment available to the 28

intended recipient in reliance upon such assumption. If such Lender or the Borrower, as the case may be, has not in fact made such payment to the Agent, the recipient of such payment shall, on demand by the Agent, repay to the Agent the amount so made available together with interest thereon in respect of each day during the period commencing on the date such amount was so made available by the Agent until the date the Agent recovers such amount at a rate per annum equal to (x) in the case of payment by a Lender, the Federal Funds Effective Rate for such day for the first three days and, thereafter, the interest rate applicable to the relevant Loan or (y) in the case of payment by the Borrower, the interest rate applicable to the relevant Loan. 2.20. Replacement of Lender. If the Borrower is required pursuant to Section 3.1, 3.2 or 3.5 to make any additional payment to any Lender or if any Lender's obligation to make or continue, or to convert Floating Rate Advances into, Eurodollar Advances shall be suspended pursuant to Section 3.3 (any Lender so affected an "Affected Lender"), the Borrower may elect, if such amounts continue to be charged or such suspension is still effective, to replace such Affected Lender as a Lender party to this Agreement, provided that no Default or Unmatured Default shall have occurred and be continuing at the time of such replacement, and provided further that, concurrently with such replacement, (i) another bank or other entity which is reasonably satisfactory to the Borrower and the Agent shall agree, as of such date, to purchase for cash the Advances and other Obligations due to the Affected Lender pursuant to an assignment substantially in the form of Exhibit C and to become a Lender for all purposes under this Agreement and to assume all obligations of the Affected Lender to be terminated as of such date and to comply with the requirements of Section 12.3 applicable to assignments, and (ii) the Borrower shall pay to such Affected Lender in same day funds on the day of such replacement (A) all interest, fees and other amounts then accrued but unpaid to such Affected Lender by the Borrower hereunder to and including the date of termination, including without limitation payments due to such Affected Lender under Sections 3.1, 3.2 and 3.5, and (B) an amount, if any, equal to the payment which would have been due to such Lender on the day of such replacement under Section 3.4 had the Loans of such Affected Lender been prepaid on such date rather than sold to the replacement Lender. ARTICLE III YIELD PROTECTION; TAXES; GENERAL INDEMNITY 3.1. Yield Protection. If, on or after the date of this Agreement, the adoption of any law or any governmental or quasi-governmental rule, regulation, policy, guideline or directive (whether or not having the force of law), or any change in the interpretation or administration thereof by any governmental or quasi-governmental authority, central bank or comparable agency charged with the interpretation or administration thereof, or compliance by any Lender or applicable Lending Installation with any request or directive (whether or not having the force of law) of any such authority, central bank or comparable agency: (i) subjects any Lender or any applicable Lending Installation to any Taxes, or changes the basis of taxation of payments (other than with respect to Excluded Taxes) to any Lender in respect of its Eurodollar Loans, or 29

(ii) imposes or increases or deems applicable any reserve, assessment, insurance charge, special deposit or similar requirement against assets of, deposits with or for the account of, or credit extended by, any Lender or any applicable Lending Installation (other than reserves and assessments taken into account in determining the interest rate applicable to Eurodollar Advances), or (iii) imposes any other condition the result of which is to increase the cost to any Lender or any applicable Lending Installation of making, funding or maintaining its Eurodollar Loans or reduces any amount receivable by any Lender or any applicable Lending Installation in connection with its Eurodollar Loans, or requires any Lender or any applicable Lending Installation to make any payment calculated by reference to the amount of Eurodollar Loans held or interest received by it, by an amount deemed material by such Lender, and the result of any of the foregoing is to increase the cost to such Lender or applicable Lending Installation of making or maintaining its Eurodollar Loans or Commitment or to reduce the return received by such Lender or applicable Lending Installation in connection with such Eurodollar Loans or Commitment, then, within 15 days of demand by such Lender, the Borrower shall pay such Lender such additional amount or amounts as will compensate such Lender for such increased cost or reduction in amount received. 3.2. Changes in Capital Adequacy Regulations. If a Lender determines the amount of capital required or expected to be maintained by such Lender, any Lending Installation of such Lender or any corporation controlling such Lender is increased as a result of a Change, then, within 15 days of demand by such Lender, the Borrower shall pay such Lender the amount necessary to compensate for any shortfall in the rate of return on the portion of such increased capital which such Lender determines is attributable to this Agreement, its Loans or its Commitment to make Loans hereunder (after taking into account such Lender's policies as to capital adequacy). "Change" means (i) any change after the date of this Agreement in the Risk-Based Capital Guidelines, or (ii) any adoption of or change in any other law, governmental or quasi-governmental rule, regulation, policy, guideline, interpretation, or directive (whether or not having the force of law) after the date of this Agreement which affects the amount of capital required or expected to be maintained by any Lender or any Lending Installation or any corporation controlling any Lender. "Risk-Based Capital Guidelines" means (i) the risk-based capital guidelines in effect in the United States on the date of this Agreement, including transition rules, and (ii) the corresponding capital regulations promulgated by regulatory authorities outside the United States implementing the July 1988 report of the Basle Committee on Banking Regulation and Supervisory Practices Entitled "International Convergence of Capital Measurements and Capital Standards," including transition rules, and any amendments to such regulations adopted prior to the date of this Agreement. 3.3. Availability of Types of Advances. If any Lender determines that maintenance of its Eurodollar Loans at a suitable Lending Installation would violate any applicable law, rule, regulation, or directive, whether or not having the force of law, or if the Required Lenders determine that (i) deposits of a type and maturity appropriate to match fund Eurodollar Advances are not available or (ii) the interest rate applicable to Eurodollar Advances does not accurately reflect the cost of making or maintaining Eurodollar Advances, then the Agent shall suspend the 30

availability of Eurodollar Advances and require any affected Eurodollar Advances to be repaid or converted to Floating Rate Advances, subject to the payment of any funding indemnification amounts required by Section 3.4. 3.4. Funding Indemnification. If any payment of a Eurodollar Advance occurs on a date which is not the last day of the applicable Interest Period, whether because of acceleration, prepayment or otherwise, or a Eurodollar Advance is not made on the date specified by the Borrower for any reason other than default by the Lenders, the Borrower will indemnify each Lender for any loss or cost incurred by it resulting therefrom, including, without limitation, any loss or cost in liquidating or employing deposits acquired to fund or maintain such Eurodollar Advance. 3.5. Taxes. (i) All payments by the Borrower to or for the account of any Lender or the Agent hereunder or under any Note shall be made free and clear of and without deduction for any and all Taxes. If the Borrower shall be required by law to deduct any Taxes from or in respect of any sum payable hereunder to any Lender or the Agent, (a) the sum payable shall be increased as necessary so that after making all required deductions (including deductions applicable to additional sums payable under this Section 3.5) such Lender or the Agent (as the case may be) receives an amount equal to the sum it would have received had no such deductions been made, (b) the Borrower shall make such deductions, (c) the Borrower shall pay the full amount deducted to the relevant authority in accordance with applicable law and (d) the Borrower shall furnish to the Agent the original copy of a receipt evidencing payment thereof within 30 days after such payment is made. (ii) In addition, the Borrower hereby agrees to pay any present or future stamp or documentary taxes and any other excise or property taxes, charges or similar levies which arise from any payment made hereunder or under any Note or from the execution or delivery of, or otherwise with respect to, this Agreement or any Note ("Other Taxes"). (iii) The Borrower hereby agrees to indemnify the Agent and each Lender for the full amount of Taxes or Other Taxes (including, without limitation, any Taxes or Other Taxes imposed on amounts payable under this Section 3.5) paid by the Agent or such Lender as a result of its Commitment, any Loans made by it hereunder, or otherwise in connection with its participation in this Agreement and any liability (including penalties, interest and expenses, unless resulting from the gross negligence or willful misconduct of the applicable indemnitee) arising therefrom or with respect thereto. Payments due under this indemnification shall be made within 30 days of the date the Agent or such Lender makes demand therefor pursuant to Section 3.6. (iv) Each Lender that is not incorporated under the laws of the United States of America or a state thereof (each a "Non-U.S. Lender") agrees that it will, not more than ten Business Days after the date of this Agreement, (i) deliver to the Agent two duly completed copies of United States Internal Revenue Service Form W-8BEN or W-8ECI, certifying in either case that such Lender is entitled to receive payments under this Agreement without deduction or withholding of any 31

United States federal income taxes, and (ii) deliver to the Agent a United States Internal Revenue Form W-8 or W-9, as the case may be, and certify that it is entitled to an exemption from United States backup withholding tax. Each Non-U.S. Lender further undertakes to deliver to each of the Borrower and the Agent (x) renewals or additional copies of such form (or any successor form) on or before the date that such form expires or becomes obsolete, and (y) after the occurrence of any event requiring a change in the most recent forms so delivered by it, such additional forms or amendments thereto as may be reasonably requested by the Borrower or the Agent. All forms or amendments described in the preceding sentence shall certify that such Lender is entitled to receive payments under this Agreement without deduction or withholding of any United States federal income taxes, unless an event (including without limitation any change in treaty, law or regulation) has occurred prior to the date on which any such delivery would otherwise be required which renders all such forms inapplicable or which would prevent such Lender from duly completing and delivering any such form or amendment with respect to it and such Lender advises the Borrower and the Agent that it is not capable of receiving payments without any deduction or withholding of United States federal income tax. (v) For any period during which a Non-U.S. Lender has failed to provide the Borrower with an appropriate form pursuant to clause (iv), above (unless such failure is due to a change in treaty, law or regulation, or any change in the interpretation or administration thereof by any governmental authority, occurring subsequent to the date on which a form originally was required to be provided), such Non-U.S. Lender shall not be entitled to indemnification under this Section 3.5 with respect to Taxes imposed by the United States; provided that, should a Non-U.S. Lender which is otherwise exempt from or subject to a reduced rate of withholding tax become subject to Taxes because of its failure to deliver a form required under clause (iv), above, the Borrower shall take such steps as such Non-U.S. Lender shall reasonably request to assist such Non-U.S. Lender to recover such Taxes. (vi) Any Lender that is entitled to an exemption from or reduction of withholding tax with respect to payments under this Agreement or any Note pursuant to the law of any relevant jurisdiction or any treaty shall deliver to the Borrower (with a copy to the Agent), at the time or times prescribed by applicable law, such properly completed and executed documentation prescribed by applicable law as will permit such payments to be made without withholding or at a reduced rate. (vii) If the U.S. Internal Revenue Service or any other governmental authority of the United States or any other country or any political subdivision thereof asserts a claim that the Agent did not properly withhold tax from amounts paid to or for the account of any Lender (because the appropriate form was not delivered or properly completed, because such Lender failed to notify the Agent of a change in circumstances which rendered its exemption from withholding ineffective, or for any other reason), such Lender shall indemnify the Agent fully for all amounts paid, directly or indirectly, by the Agent as tax, withholding therefor, or 32

otherwise, including penalties and interest, and including taxes imposed by any jurisdiction on amounts payable to the Agent under this subsection, together with all costs and expenses related thereto (including attorneys fees and time charges of attorneys for the Agent, which attorneys may be employees of the Agent). The obligations of the Lenders under this Section 3.5(vii) shall survive the payment of the Obligations and termination of this Agreement. 3.6. Lender Statements; Survival of Indemnity. To the extent reasonably possible, each Lender shall designate an alternate Lending Installation with respect to its Eurodollar Loans to reduce any liability of the Borrower to such Lender under Sections 3.1, 3.2 and 3.5 or to avoid the unavailability of Eurodollar Advances under Section 3.3, so long as such designation is not, in the judgment of such Lender, disadvantageous to such Lender. Each Lender shall deliver a written statement of such Lender to the Borrower (with a copy to the Agent) as to the amount due, if any, under Section 3.1, 3.2, 3.4 or 3.5. Such written statement shall set forth in reasonable detail the calculations upon which such Lender determined such amount and shall be final, conclusive and binding on the Borrower in the absence of manifest error. Determination of amounts payable under such Sections in connection with a Eurodollar Loan shall be calculated as though each Lender funded its Eurodollar Loan through the purchase of a deposit of the type and maturity corresponding to the deposit used as a reference in determining the Eurodollar 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 of any Lender shall be payable on demand after receipt by the Borrower of such written statement. The obligations of the Borrower under Sections 3.1, 3.2, 3.4, 3.5 and 3.7 shall survive payment of the Obligations and termination of this Agreement. 3.7. General Indemnity. 3.7.1. Indemnification. The Borrower does hereby assume liability for, and does hereby agree to indemnify, defend, protect, save and keep harmless, on an After-Tax Basis, each Indemnified Person from and against any and all liabilities, obligations, losses, damages, penalties, claims (including, without limitation, claims involving strict or absolute liability in tort, warranty claims, claims based on negligence, products liability or statutory liability or claims for enforcement, cleanup, removal, response, remedial or other actions or damages, contribution, indemnification, cost recovery, compensation or injunctive relief pursuant to any Environmental Law or alleged injury or threat of injury, to health, safety, the environment or natural resources), actions, suits, costs, expenses and disbursements (including, without limitation, reasonable legal fees and expenses) of any kind and nature whatsoever (all of the foregoing being referred to as "Claims") which may be imposed on, incurred by or asserted against such Indemnified Person, whether or not such Indemnified Person shall also be indemnified as to any such Claim by any other Person, in any way relating to or arising out of: (1) this Agreement or any other Transaction Document, or any document contemplated hereby or thereby; or the execution, delivery or performance or non-performance or enforcement of any of the terms of this Agreement or any other Transaction Document by the Borrower, the Beneficiary, 33

the Parent Guarantor, the Owner Trustee, the Agent or the Lenders or any other Person; (2) the Platform, the Project or any part thereof or the purchase, manufacture, design, financing, refinancing, construction, acceptance, rejection, ownership, acquisition, delivery, non-delivery, occupancy, lease, ground lease, sublease, rental, preparation, installation, modification, substitution, possession, use, non-use, operation, maintenance, condition, registration, repair, transportation, transfer of title, any action taken by any Obligor in connection therewith, abandonment, rental, importation, exportation, sale, retirement, return, storage or other disposition of the Platform, the Project or any part thereof or any accident in connection therewith (including, without limitation, latent and other defects, whether or not discoverable, whether preexisting or not and any Claim for patent, trademark or copyright infringement) or the failure of the Platform to be located wholly within the Site; (3) the performance of any labor or services or the furnishing of any materials or other property in respect of the Platform or any part thereof by or on behalf of or with the knowledge of any Obligor or any Affiliate; (4) any negligence or tortious acts on the part of any Obligor or any Affiliate or any agents, contractors, sublessee, franchisees, licensees or invitees thereof; (5) any alterations, changes, modifications, new construction or demolition of the Platform or any part thereof; (6) any violation of law; or any breach of any covenant, warranty or representation in any Transaction Document or any certificate required to be delivered pursuant to any Transaction Document by any Obligor or any Affiliate; (7) the offer, issue, sale, purchase or delivery of any interest in the Trust Estate (including the trust certificates) or the Trust Agreement or any similar interest or in any way resulting from or arising out of the Trust Agreement and the Trust Estate (including Claims arising under or resulting from applicable Federal, state or foreign securities laws or common law); (8) the imposition of any Lien on the Platform or the Project (other than Permitted Project Liens or Trustee Liens) or the enforcement of any agreement, restriction or legal requirement affecting the Platform or the Project; (9) a disposition of the Project; (10) the transactions contemplated by the Transaction Documents, in respect of the application of Parts 4 and 5 of Subtitle B of Title I of ERISA and any prohibited transaction described in Section 4975(c) of the Code; 34

(11) the presence, Release or threat of Release into the environment of any Hazardous Substances; the presence on, under or around the Property, wherever located, of any Hazardous Substances, or any Releases, threats of Release or discharges of any Hazardous Substances on, under, around or from any Sites, irrespective of when such presence, Release, threat of Release or discharge of Hazardous Substances occurred or originated; any activity carried on or undertaken on or off the Platform in connection with the handling, treatment, removal, storage, decontamination, clean-up, transport or disposal of any Hazardous Substances (including, without limitation, from any corrective action plan and the development and implementation thereof); any residual contamination on, under, around or from the Platform and affecting any natural resources or any property of others; in any and all such circumstances irrespective of whether any of such activities were undertaken in accordance with Applicable Law, or whether claims with respect thereto are made pursuant to Environmental Law; or (12) the misapplication of insurance or condemnation proceeds by any Obligor or any other Person. 3.7.2. Survival. Unless otherwise expressly provided in the Loan Documents, the obligations, agreements, rights and liabilities of the Obligors, the Trustee and each Indemnified Person arising under this Section shall continue in full force and effect, notwithstanding the payment of the Obligations or other termination of this Agreement. Until all obligations have been met, all liabilities arising under this Section 3.7 shall be enforceable by the Obligors, the Trustee and each Indemnified Person and their successors, assigns and agents. The foregoing indemnification provisions shall not be limited during the Construction of the Platform. 3.7.3. Certain Exceptions. Notwithstanding the foregoing, the Obligors shall not assume liability for or indemnify, defend, protect, save and keep harmless pursuant to Section 3.7.1 hereof (i) any Indemnified Person for any Claim to the extent it results from the material incorrectness of, or any failure on the part of such Indemnified Person to comply with, any representation, warranty, agreement or covenant of such Indemnified Person in favor of the Beneficiary in any Transaction Document unless such failure to comply resulted in whole or in part from any default by any Obligor under any Transaction Document; provided, however, that the material incorrectness of, or the failure of any Indemnified Person to comply with, any such representation, warranty, agreement or covenant shall not affect the rights of any other Indemnified Person hereunder; (ii) any Indemnified Person for any Claim to the extent resulting from acts which would constitute the willful misconduct or gross negligence of such Indemnified Person or a related Indemnified Person; (it being agreed that for purposes of this clause (ii) the Trustee shall not be deemed a related Indemnified Person of the Certificate Holders) provided that: (A) gross negligence or willful misconduct will not be imputed to such Indemnified Person or any related Indemnified Person solely as a result of the Trustee's ownership the Property; (B) the willful misconduct or gross negligence of an Indemnified Person shall not affect the rights of any other Indemnified Person hereunder; and (C) with respect to the Trustee, it shall not constitute willful misconduct or gross 35

negligence of Wilmington Trust Company to rely on the written instructions of the Certificate Holders; and (iii) any Indemnified Person for any Claim to the extent resulting from the imposition of any Trustee Lien attributable to it. 3.7.4. Claims Procedure. An Indemnified Person shall, after obtaining actual knowledge thereof, promptly notify the Borrower of any Claim as to which indemnification is sought (unless any Obligor theretofore has notified such Indemnified Person of such Claim); provided, however, that the failure to give such notice shall not release the Borrower from any of its obligations under this Section 3.7, except to the extent that failure to give notice of any action, suit or proceeding against such Indemnified Person is shown to increase the Borrower's liability under such Claim from that which would have existed if the failure to give notice had not occurred. Subject to the following paragraph, the Borrower agrees to defend such Claim and shall at its sole cost and expense be entitled to control, and shall assume full responsibility for, the defense of such Claim; provided, however, that the Borrower shall keep the Indemnified Person that is the subject of such proceeding fully apprised of the status of such proceeding and shall provide such Indemnified Person with all information with respect to such proceeding as such Indemnified Person reasonably requests; and provided, further, that in the event the Borrower fails to defend such Claim, the Borrower shall pay the reasonable costs and expenses (including reasonable legal fees and expenses) of the Indemnified Person in defending such Claim. Notwithstanding any of the foregoing to the contrary, the Borrower shall not be entitled to control and assume responsibility for the defense of such Claim if (1) a Default or Unmatured Default exists, and the Indemnified Person notifies the Borrower that it is no longer permitted to control the defense of such Claim, (2) such proceeding involves any material danger of the sale, forfeiture or loss of, or the creation of any Lien (other than any Permitted Lien or bonded liens which would become liens under item (vi) of the definition of Permitted Project Liens) on, the Platform or the Project, (3) in the good faith opinion of such Indemnified Person, there exists an actual or potential conflict of interest such that it is advisable for such Indemnified Person to retain control of such proceeding or (4) such Claim or liability involves a risk of criminal actions or liability to such Indemnified Person. In the circumstances described in clauses (1) through (4), the Indemnified Person shall be entitled to control and assume responsibility for the defense of such Claim or liability at the expense of the Borrower. In addition, any Indemnified Person, at its own expense, may (A) participate in any proceeding controlled by the Borrower pursuant to this Section 3.7.4 and (B) employ separate counsel. The Borrower may in any event participate in all such proceedings at its own cost. Nothing contained in this Section 3.7 shall be deemed to require an Indemnified Person to contest any Claim or to assume responsibility for or control of any judicial proceeding with respect thereto. 3.7.5. Subrogation. If a Claim indemnified by the Borrower under this Section 3.7 is paid in full by the Borrower and/or an insurer under a policy of insurance maintained by the Borrower, or if payment of the Claim has otherwise been provided for in full in a manner reasonably satisfactory to the Indemnified Person, the Borrower 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 36

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 Default exists, if an Indemnified Person receives any refund, in whole or in part, with respect to any Claim paid by the Borrower hereunder, it shall promptly pay over the amount refunded (but not in excess of the amount the Borrower 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 the Borrower; provided, however, if any Default or Payment Default exists, any such refund shall be retained by, or paid over to, the Agent to be held and applied against amounts payable by the Borrower hereunder and under the other Loan Documents. 3.7.6. Insured Claims. In the case of any Claim indemnified by the Borrower hereunder which is covered by a policy of insurance maintained by or for the benefit of the Borrower, each Indemnified Person agrees to cooperate, at the expense of the Borrower, 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 Borrower of its obligation to indemnify such Indemnified Person except to the extent that the Borrower or its insurer is materially prejudiced as a result of such failure). 3.7.7. Waiver of Certain Claims. The Borrower hereby waives and releases any Claim now or hereafter existing against any Indemnified Person out of death or personal injury to personnel of any Obligor (including its directors, officers, employees, agents and servants), loss or damage to property of any Obligor or any Affiliates of any thereof, of the loss of use of any property of any Obligor or any Affiliates of any thereof, which may result from or arise out of the condition, use or operation of the Platform or the Project, including, without limitation, any latent or patent defect whether or not discoverable. 3.7.8. Consent. Unless a Default or Unmatured Default exists, the Borrower shall not be liable hereunder for any settlement of any loss, claim, damage, liability or action effected without its consent.

6.19.2. Reappraisal Upon Completion. Within sixty (60) days from the Completion Date for the Platform, the Agent shall obtain, at Borrower's sole cost and expense, a new Appraisal of the Property taking into account such Completion (the "Completion Appraisal") which Completion Appraisal shall be delivered to the Agent within sixty (60) days after the Completion Date. Such Completion Appraisal shall use methodology similar to that of the Appraisal delivered in connection with the initial lease financing in favor of the Beneficiary as of November 8, 2001, with appropriate changes in assumptions and taking into account the terms of Joint Operating Agreement, as amended. In the event such Completion Appraisal shall conclude that the Fair Market Sales Value of the Platform upon such Completion, multiplied by the Borrower's Percentage Undivided Interest, is less than the Funding Period Termination Balance (such amount, a "FMV Shortfall"), the Borrower shall make a special prepayment of the Funding Period Termination Balance to the Agent equal to such FMV Shortfall. 6.20. Closing Date Deliveries. Contemporaneously herewith, the Borrower, the Beneficiary and the Parent Guarantor shall deliver the documents referred to on Schedule 8 hereto, and the Beneficiary shall pay to BOLSC the Certificate Purchase Price for the Certificate by wire transfer of immediately available funds to the account specified by BOLSC. Contemporaneously therewith, the Agent shall cause the Notes issued under the Loan Agreement to be canceled, such Notes being replaced by the Note to be issued by the Borrower as described on Schedule 8 hereto. 6.21. Abandonment Costs. At no time will the Parent Guarantor incur or accrue or permit its Subsidiaries to incur or accrue, in the aggregate during the term of the Loans, in excess of $50,000,000 in plug and abandonment costs for its and their Properties ("Abandonment Costs") without the prior written consent of the Agent; provided that upon delivery by the Parent Guarantor to the Agent of a written amendment to the Revolving Credit Agreement which has been fully executed, together with a certification from the Parent Guarantor that such amendment is in full force and effect, if such amendment increases the maximum amount of Abandonment Costs permitted thereunder to an amount in excess of $50,000,000, the Agent will cause the foregoing covenant to be revised to increase the amount set forth in this Section 6.21 to the lesser of (x) such increased amount and (y) $100,000,000. 6.22. Notice of Transactions. Not less than 30 days prior to the consummation by the Parent Guarantor or any Subsidiary of any transaction which (i) requires consent under or waiver of the Revolving Credit Agreement, or (ii) is an acquisition with a transaction value of $20,000,000 or more, the Parent Guarantor will provide to the Agent notice of such transaction in reasonable detail. 6.23. Sale of Working Interest. Until the payment of the Obligations in full, the Beneficiary 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 the Beneficiary 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 3(g) of Schedule 6 of this Agreement (it being understood and agreed that Beneficiary 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). 53

ARTICLE VIII ACCELERATION, WAIVERS, AMENDMENTS AND REMEDIES 8.1. Acceleration. If any Default described in Section 7.6 or 7.7 occurs, the obligations of the Lenders to make Loans hereunder shall automatically terminate and the Obligations shall immediately become due and payable without any election or action on the part of the Agent or any Lender. If any other Default occurs, the Required Lenders (or the Agent with the consent of the Required Lenders) may terminate or suspend the obligations of the Lenders to make Loans hereunder, or declare the Obligations to be due and payable, or both, whereupon the Obligations shall become immediately due and payable, without presentment, demand, protest or notice of any kind, all of which each of the Obligors hereby expressly waives. If, within 30 days after acceleration of the maturity of the Obligations or termination of the obligations of the Lenders to make Loans hereunder as a result of any Default (other than any Default as described in Section 7.6 or 7.7) and before any judgment or decree for the payment of the Obligations due shall have been obtained or entered, the Required Lenders (in their sole 56

discretion) shall so direct, the Agent shall, by notice to the Borrower, rescind and annul such acceleration and/or termination. 8.2. Amendments. Subject to the provisions of this Section 8.2, the Required Lenders (or the Agent with the consent in writing of the Required Lenders) and the Borrower may enter into agreements supplemental hereto for the purpose of adding or modifying any provisions to the Loan Documents or changing in any manner the rights of the Lenders or the Borrower hereunder or waiving any Default hereunder; provided, however, that no such supplemental agreement shall, without the consent of all of the Lenders: (i) Extend the final maturity of any Loan or postpone any regularly scheduled payment of principal of any Loan or forgive all or any portion of the principal amount thereof, or reduce the rate or extend the time of payment of interest or fees thereon. (ii) Reduce the percentage specified in the definition of Required Lenders. (iii) Extend the Facility Termination Date pr the Funding Period Termination Date, or reduce the amount or extend the payment date for, the mandatory payments required under Section 2.2, or increase the amount of the Aggregate Commitment or of the Commitment of any Lender hereunder, or permit the Borrower to assign its rights under this Agreement. (iv) Amend this Section 8.2. (v) Release any guarantor of any Advance or, except as provided in the Collateral Documents, release, or agree to subordinate the Lenders' Liens with respect to, all or substantially all of the Collateral. No amendment of any provision of this Agreement relating to the Agent shall be effective without the written consent of the Agent. The Agent may waive payment of the fee required under Section 12.3.3 without obtaining the consent of any other party to this Agreement. 8.3. Preservation of Rights. No delay or omission of the Lenders or the Agent to exercise any right under the Loan Documents shall impair such right or be construed to be a waiver of any Default or an acquiescence therein, and the making of a Loan notwithstanding the existence of a Default or the inability of any Obligor to satisfy the conditions precedent to such Loan shall not constitute any waiver or acquiescence. Any single or partial exercise of any such right shall not preclude other or further exercise thereof or the exercise of any other right, and no waiver, amendment or other variation of the terms, conditions or provisions of the Loan Documents whatsoever shall be valid unless in writing signed by the Lenders required pursuant to Section 8.2, and then only to the extent in such writing specifically set forth. All remedies contained in the Loan Documents or by law afforded shall be cumulative and all shall be available to the Agent and the Lenders until the Obligations have been paid in full. ARTICLE IX GENERAL PROVISIONS 57

9.1. Survival of Representations and Covenants. All representations and warranties and covenants of the Obligors contained in this Agreement shall be joint and several and shall survive the making of the Loans herein contemplated until final and unconditional repayment in full of the Loans; provided, however, that all indemnities (and related defense and hold harmless obligations) shall survive any repayment of the Loans. 9.2. Governmental Regulation. Anything contained in this Agreement to the contrary notwithstanding, no Lender shall be obligated to extend credit to the Borrower in violation of any limitation or prohibition provided by any applicable statute or regulation. 9.3. Headings. Section headings in the Loan Documents are for convenience of reference only, and shall not govern the interpretation of any of the provisions of the Loan Documents. 9.4. Entire Agreement. The Loan Documents embody the entire agreement and understanding among the Obligors, the Agent and the Lenders and supersede all prior agreements and understandings among the Borrower, the Agent and the Lenders relating to the subject matter thereof other than those contained in the Fee Letter, which shall survive and remain in full force and effect during the term of this Agreement. 9.5. Several Obligations; Benefits of this Agreement. The respective obligations of the Lenders hereunder are several and not joint and no Lender shall be the partner or agent of any other (except to the extent to which the Agent is authorized to act as such). The failure of any Lender to perform any of its obligations hereunder shall not relieve any other Lender from any of its obligations hereunder. This Agreement shall not be construed so as to confer any right or benefit upon any Person other than the parties to this Agreement and their respective successors and assigns, provided, however, that the parties hereto expressly agree that the Arranger shall enjoy the benefits of the provisions of Sections 9.6, 9.10 and 10.11 to the extent specifically set forth therein and shall have the right to enforce such provisions on its own behalf and in its own name to the same extent as if it were a party to this Agreement. 9.6. Expenses; Indemnification. (i) The Obligors covenant, jointly and severally to reimburse the Agent and the Arranger for any costs, internal charges and out-of-pocket expenses (including attorneys' fees and time charges of attorneys for the Agent, which attorneys may be employees of the Agent) paid or incurred by the Agent or the Arranger in connection with any waiver, amendment or modification of the Loan Documents proposed by any Obligor (whether or not granted) or entered into by any Obligor. The Obligors shall not be liable for any legal fees of the Agent and the Arranger in connection with (x) the negotiation of this Agreement and the other Loan Documents or (y) any syndication of the Loans. The Obligors also agrees covenant, jointly and severally, to reimburse the Agent, the Arranger and the Lenders for any costs, internal charges and out-of-pocket expenses (including attorneys' fees and time charges of attorneys for the Agent, the Arranger and the Lenders, which attorneys may be employees of the Agent, the Arranger or the Lenders) paid or incurred by the Agent, the Arranger or any Lender in connection with the collection and enforcement of the Loan Documents. Expenses being reimbursed by the Obligors under this Section include, without limitation, the costs and expenses incurred in connection with the Reports described in the following sentence. The Obligors acknowledge that from time to time Bank One may prepare and may distribute to the Lenders 58

(but shall have no obligation or duty to prepare or to distribute to the Lenders) certain audit reports (the "Reports") pertaining to the Borrower's assets for internal use by Bank One from information furnished to it by or on behalf of the Borrower, after Bank One has exercised its rights of inspection pursuant to this Agreement. (ii) The Obligors hereby further jointly and severally agree to indemnify the Agent, the Arranger, each Lender, their respective affiliates, and each of their directors, officers and employees against all losses, claims, damages, penalties, judgments, liabilities and expenses (including, without limitation, all expenses of litigation or preparation therefor whether or not the Agent, the Arranger, any Lender or any affiliate is a party thereto) which any of them may pay or incur arising out of or relating to this Agreement, the other Loan Documents, the transactions contemplated hereby or the direct or indirect application or proposed application of the proceeds of any Loan hereunder except to the extent that they are determined in a final non-appealable judgment by a court of competent jurisdiction to have resulted from the gross negligence or willful misconduct of the party seeking indemnification. The obligations of the Obligors under this Section 9.6 shall survive the termination of this Agreement. 9.7. Numbers of Documents. All statements, notices, closing documents, and requests hereunder shall be furnished to the Agent with sufficient counterparts so that the Agent may furnish one to each of the Lenders. 9.8. Accounting. Except as provided to the contrary herein, all accounting terms used herein shall be interpreted and all accounting determinations hereunder shall be made in accordance with Agreement Accounting Principles[, except that any calculation or determination which is to be made on a consolidated basis shall be made for the Borrower and all its Subsidiaries, including those Subsidiaries, if any, which are unconsolidated on the Borrower's audited financial statements]. 9.9. Severability of Provisions. Any provision in any Loan Document that is held to be inoperative, unenforceable, or invalid in any jurisdiction shall, as to that jurisdiction, be inoperative, unenforceable, or invalid without affecting the remaining provisions in that jurisdiction or the operation, enforceability, or validity of that provision in any other jurisdiction, and to this end the provisions of all Loan Documents are declared to be severable. 9.10. Nonliability of Lenders. The relationship between the Obligors on the one hand and the Lenders and the Agent on the other hand shall be solely that of borrower and lender. Neither the Agent, the Arranger nor any Lender shall have any fiduciary responsibilities to the Obligors. Neither the Agent, the Arranger nor any Lender undertakes any responsibility to the Obligor to review or inform the Obligors of any matter in connection with any phase of any Obligor's business or operations. The Obligors agree that neither the Agent, the Arranger nor any Lender shall have liability to any Obligor (whether sounding in tort, contract or otherwise) for losses suffered by any Obligor in connection with, arising out of, or in any way related to, the transactions contemplated and the relationship established by the Loan Documents, or any act, omission or event occurring in connection therewith, unless it is determined in a final non-appealable judgment by a court of competent jurisdiction that such losses resulted from the 59

gross negligence or willful misconduct of the party from which recovery is sought. Neither the Agent, the Arranger nor any Lender shall have any liability with respect to, and the Obligors hereby waive, release and agree not to sue for, any special, indirect, consequential or punitive damages suffered by any Obligor in connection with, arising out of, or in any way related to the Loan Documents or the transactions contemplated thereby. 9.11. Confidentiality. Each Lender agrees to hold any confidential information which it may receive from the Obligors pursuant to this Agreement in confidence, except for disclosure (i) to its Affiliates and to other Lenders and their respective Affiliates, (ii) to legal counsel, accountants, and other professional advisors to such Lender or to a Transferee, (iii) to regulatory officials, (iv) to any Person as requested pursuant to or as required by law, regulation, or legal process, (v) to any Person in connection with any legal proceeding to which such Lender is a party, (vi) to such Lender's direct or indirect contractual counterparties in swap agreements or to legal counsel, accountants and other professional advisors to such counterparties, (vii) permitted by Section 12.4 and (viii) to rating agencies if requested or required by such agencies in connection with a rating relating to the Advances hereunder. 9.12. Nonreliance. Each Lender hereby represents that it is not relying on or looking to any margin stock (as defined in Regulation U of the Board of Governors of the Federal Reserve System) for the repayment of the Loans provided for herein. 9.13. Disclosure. Each Obligor and each Lender hereby acknowledge and agree that Bank One and/or its Affiliates from time to time may hold investments in, make other loans to or have other relationships with any Obligor and its Affiliates. ARTICLE X THE AGENT 10.1. Appointment; Nature of Relationship. Bank One, NA is hereby appointed by each of the Lenders as its contractual representative (herein referred to as the "Agent") hereunder and under each other Loan Document, and each of the Lenders irrevocably authorizes the Agent to act as the contractual representative of such Lender with the rights and duties expressly set forth herein and in the other Loan Documents. The Agent agrees to act as such contractual representative upon the express conditions contained in this Article X. Notwithstanding the use of the defined term "Agent," it is expressly understood and agreed that the Agent shall not have any fiduciary responsibilities to any Lender by reason of this Agreement or any other Loan Document and that the Agent is merely acting as the contractual representative of the Lenders with only those duties as are expressly set forth in this Agreement and the other Loan Documents. In its capacity as the Lenders' contractual representative, the Agent (i) does not hereby assume any fiduciary duties to any of the Lenders, (ii) is a "representative" of the Lenders within the meaning of the term "secured party" as defined in the Illinois Uniform Commercial Code and (iii) is acting as an independent contractor, the rights and duties of which are limited to those expressly set forth in this Agreement and the other Loan Documents. Each of the Lenders hereby agrees to assert no claim against the Agent on any agency theory or any other theory of liability for breach of fiduciary duty, all of which claims each Lender hereby waives. 60

10.2. Powers. The Agent shall have and may exercise such powers under the Loan Documents as are specifically delegated to the Agent by the terms of each thereof, together with such powers as are reasonably incidental thereto. The Agent shall have no implied duties to the Lenders, or any obligation to the Lenders to take any action thereunder except any action specifically provided by the Loan Documents to be taken by the Agent. 10.3. General Immunity. Neither the Agent nor any of its directors, officers, agents or employees shall be liable to the Borrower, the Lenders or any Lender for any action taken or omitted to be taken by it or them hereunder or under any other Loan Document or in connection herewith or therewith except to the extent such action or inaction is determined in a final non-appealable judgment by a court of competent jurisdiction to have arisen from the gross negligence or willful misconduct of such Person. 10.4. No Responsibility for Loans, Recitals, etc. Neither the Agent nor any of its directors, officers, agents or employees shall be responsible for or have any duty to ascertain, inquire into, or verify (a) any statement, warranty or representation made in connection with any Loan Document or any borrowing hereunder; (b) the performance or observance of any of the covenants or agreements of any obligor under any Loan Document, including, without limitation, any agreement by an obligor to furnish information directly to each Lender; (c) the satisfaction of any condition specified in Article IV, except receipt of items required to be delivered solely to the Agent; (d) the existence or possible existence of any Default or Unmatured Default; (e) the validity, enforceability, effectiveness, sufficiency or genuineness of any Loan Document or any other instrument or writing furnished in connection therewith; (f) the value, sufficiency, creation, perfection or priority of any Lien in any collateral security; or (g) the financial condition of any Obligor or any guarantor of any of the Obligations or of any of any Obligor's or any such guarantor's respective Subsidiaries. The Agent shall have no duty to disclose to the Lenders information that is not required to be furnished by any Obligor to the Agent at such time, but is voluntarily furnished by any Obligor to the Agent (either in its capacity as Agent or in its individual capacity). 10.5. Action on Instructions of Lenders. The Agent shall in all cases be fully protected in acting, or in refraining from acting, hereunder and under any other Loan Document in accordance with written instructions signed by the Required Lenders, and such instructions and any action taken or failure to act pursuant thereto shall be binding on all of the Lenders. The Lenders hereby acknowledge that the Agent shall be under no duty to take any discretionary action permitted to be taken by it pursuant to the provisions of this Agreement or any other Loan Document unless it shall be requested in writing to do so by the Required Lenders. The Agent shall be fully justified in failing or refusing to take any action hereunder and under any other Loan Document unless it shall first be indemnified to its satisfaction by the Lenders pro rata against any and all liability, cost and expense that it may incur by reason of taking or continuing to take any such action. 10.6. Employment of Agents and Counsel. The Agent may execute any of its duties as Agent hereunder and under any other Loan Document by or through employees, agents, and attorneys-in-fact and shall not be answerable to the Lenders, except as to money or securities received by it or its authorized agents, for the default or misconduct of any such agents or attorneys-in-fact selected by it with reasonable care. The Agent shall be entitled to advice of 61

counsel concerning the contractual arrangement between the Agent and the Lenders and all matters pertaining to the Agent's duties hereunder and under any other Loan Document. 10.7. Reliance on Documents; Counsel. The Agent shall be entitled to rely upon any Note, notice, consent, certificate, affidavit, letter, telegram, statement, paper or document believed by it to be genuine and correct and to have been signed or sent by the proper person or persons, and, in respect to legal matters, upon the opinion of counsel selected by the Agent, which counsel may be employees of the Agent. 10.8. Agent's Reimbursement and Indemnification. The Lenders agree to reimburse and indemnify the Agent ratably in proportion to their respective Commitments (or, if the Commitments have been terminated, in proportion to their Commitments immediately prior to such termination) (i) for any amounts not reimbursed by the Obligors for which the Agent is entitled to reimbursement by any Obligor under the Loan Documents, (ii) for any other expenses incurred by the Agent on behalf of the Lenders, in connection with the preparation, execution, delivery, administration and enforcement of the Loan Documents (including, without limitation, for any expenses incurred by the Agent in connection with any dispute between the Agent and any Lender or between two or more of the Lenders) and (iii) for any liabilities, obligations, losses, damages, penalties, actions, judgments, suits, costs, expenses or disbursements of any kind and nature whatsoever which may be imposed on, incurred by or asserted against the Agent in any way relating to or arising out of the Loan Documents or any other document delivered in connection therewith or the transactions contemplated thereby (including, without limitation, for any such amounts incurred by or asserted against the Agent in connection with any dispute between the Agent and any Lender or between two or more of the Lenders), or the enforcement of any of the terms of the Loan Documents or of any such other documents, provided that (i) no Lender shall be liable for any of the foregoing to the extent any of the foregoing is found in a final non-appealable judgment by a court of competent jurisdiction to have resulted from the gross negligence or willful misconduct of the Agent and (ii) any indemnification required pursuant to Section 3.5(vii) shall, notwithstanding the provisions of this Section 10.8, be paid by the relevant Lender in accordance with the provisions thereof. The obligations of the Lenders under this Section 10.8 shall survive payment of the Obligations and termination of this Agreement. 10.9. Notice of Default. The Agent shall not be deemed to have knowledge or notice of the occurrence of any Default or Unmatured Default hereunder unless the Agent has received written notice from a Lender or an Obligor referring to this Agreement describing such Default or Unmatured 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 Lenders. 10.10. Rights as a Lender. In the event the Agent is a Lender, the Agent shall have the same rights and powers hereunder and under any other Loan Document with respect to its Commitment and its Loans as any Lender and may exercise the same as though it were not the Agent, and the term "Lender" or "Lenders" shall, at any time when the Agent is a Lender, 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 Loan Document, with any Obligor or any of its Subsidiaries in which such Obligor or such 62

Subsidiary is not restricted hereby from engaging with any other Person. The Agent, in its individual capacity, is not obligated to remain a Lender. 10.11. Lender Credit Decision. Each Lender acknowledges that it has, independently and without reliance upon the Agent, the Arranger or any other Lender and based on the financial statements prepared by the Obligors and such other documents and information as it has deemed appropriate, made its own credit analysis and decision to enter into this Agreement and the other Loan Documents. Each Lender also acknowledges that it will, independently and without reliance upon the Agent, the Arranger 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 and the other Loan Documents. 10.12. Successor Agent. The Agent may resign at any time by giving written notice thereof to the Lenders and the Borrower, 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. The Agent may be removed at any time with or without cause by written notice received by the Agent from the Required Lenders, such removal to be effective on the date specified by the Required Lenders. Upon any such resignation or removal, the Required Lenders shall have the right to appoint, on behalf of the Borrower and the Lenders, a successor Agent. If no successor Agent shall have been so appointed by the Required Lenders 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 Borrower and the Lenders, a successor Agent. Notwithstanding the previous sentence, the Agent may at any time without the consent of the Borrower or any Lender, 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 Lenders may perform all the duties of the Agent hereunder and the Borrower shall make all payments in respect of the Obligations to the applicable Lender and for all other purposes shall deal directly with the Lenders. 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. Upon the effectiveness of the resignation or removal of the Agent, the resigning or removed Agent shall be discharged from its duties and obligations hereunder and under the Loan Documents. After the effectiveness of the resignation or removal of an Agent, the provisions of this Article X 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 Loan 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 10.12, 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. 10.13. Delegation to Affiliates. The Obligors and the Lenders agree that the Agent may delegate any of its duties under this 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 Articles IX and X. 63

10.14. Execution of Collateral Documents. The Lenders hereby empower and authorize the Agent to execute and deliver to the Obligors on their behalf the Security Agreement(s) and all related financing statements and any financing statements, agreements, documents or instruments as shall be necessary or appropriate to effect the purposes of the Security Agreement(s). 10.15. Collateral Releases. The Lenders hereby empower and authorize the Agent to execute and deliver to the Obligors on their behalf any agreements, documents or instruments as shall be necessary or appropriate to effect any releases of Collateral which shall be permitted by the terms hereof or of any other Loan Document or which shall otherwise have been approved by the Required Lenders (or, if required by the terms of Section 8.2, all of the Lenders) in writing. ARTICLE XI SETOFF; RATABLE PAYMENTS 11.1. Setoff. In addition to, and without limitation of, any rights of the Lenders under applicable law, if any Obligor becomes insolvent, however evidenced, or any Default occurs, any and all deposits (including all account balances, whether provisional or final and whether or not collected or available) and any other Indebtedness at any time held or owing by any Lender or any Affiliate of any Lender to or for the credit or account of any Obligor may be offset and applied toward the payment of the Obligations owing to such Lender, whether or not the Obligations, or any part thereof, shall then be due. 11.2. Ratable Payments. If any Lender, whether by setoff or otherwise, has payment made to it upon its Loans (other than payments received pursuant to Section 3.1, 3.2, 3.4 or 3.5) in a greater proportion than that received by any other Lender, such Lender agrees, promptly upon demand, to purchase a portion of the Loans held by the other Lenders so that after such purchase each Lender will hold its ratable proportion of Loans. If any Lender, whether in connection with setoff or amounts which might be subject to setoff or otherwise, receives collateral or other protection for its Obligations or such amounts which may be subject to setoff, such Lender agrees, promptly upon demand, to take such action necessary such that all Lenders share in the benefits of such collateral ratably in proportion to their Loans. In case any such payment is disturbed by legal process, or otherwise, appropriate further adjustments shall be made. ARTICLE XII BENEFIT OF AGREEMENT; ASSIGNMENTS; PARTICIPATIONS 12.1. Successors and Assigns. The terms and provisions of the Loan Documents shall be binding upon and inure to the benefit of the Obligors and the Lenders and their respective successors and assigns permitted hereby, except that (i) no Obligor shall have the right to assign its rights or obligations under the Loan Documents without the prior written consent of each Lender, (ii) any assignment by any Lender must be made in compliance with Section 12.3, and (iii) any transfer by Participation must be made in compliance with Section 12.2. Any attempted assignment or transfer by any party not made in compliance with this Section 12.1 shall be null 64

and void, unless such attempted assignment or transfer is treated as a participation in accordance with Section 12.3.2. The parties to this Agreement acknowledge that clause (ii) of this Section 12.1 relates only to absolute assignments and this Section 12.1 does not prohibit assignments creating security interests, including, without limitation, (x) any pledge or assignment by any Lender of all or any portion of its rights under this Agreement and any Note to a Federal Reserve Bank or (y) in the case of a Lender which is a Fund, any pledge or assignment of all or any portion of its rights under this Agreement and any Note to its trustee in support of its obligations to its trustee; provided, however, that no such pledge or assignment creating a security interest shall release the transferor Lender from its obligations hereunder unless and until the parties thereto have complied with the provisions of Section 12.3. The Agent may treat the Person which made any Loan or which holds any Note as the owner thereof for all purposes hereof unless and until such Person complies with Section 12.3; provided, however, that the Agent may in its discretion (but shall not be required to) follow instructions from the Person which made any Loan or which holds any Note to direct payments relating to such Loan or Note to another Person. Any assignee of the rights to any Loan or any Note agrees by acceptance of such assignment to be bound by all the terms and provisions of the Loan Documents. Any request, authority or consent of any Person, who at the time of making such request or giving such authority or consent is the owner of the rights to any Loan (whether or not a Note has been issued in evidence thereof), shall be conclusive and binding on any subsequent holder or assignee of the rights to such Loan. 12.2. Participations. 12.2.1. Permitted Participants; Effect. Any Lender may at any time sell to one or more banks or other entities ("Participants") participating interests in any Loan owing to such Lender, any Note held by such Lender, any Commitment of such Lender or any other interest of such Lender under the Loan Documents. In the event of any such sale by a Lender of participating interests to a Participant, such Lender's obligations under the Loan Documents shall remain unchanged, such Lender shall remain solely responsible to the other parties hereto for the performance of such obligations, such Lender shall remain the owner of its Loans and the holder of any Note issued to it in evidence thereof for all purposes under the Loan Documents, all amounts payable by the Borrower under this Agreement shall be determined as if such Lender had not sold such participating interests, and the Borrower and the Agent shall continue to deal solely and directly with such Lender in connection with such Lender's rights and obligations under the Loan Documents. 12.2.2. Voting Rights. Each Lender shall retain the sole right to approve, without the consent of any Participant, any amendment, modification or waiver of any provision of the Loan Documents other than any amendment, modification or waiver with respect to any Loan or Commitment in which such Participant has an interest which would require consent of all of the Lenders pursuant to the terms of Section 8.2 or of any other Loan Document. 12.2.3. Benefit of Certain Provisions. The Obligors agree that each Participant shall be deemed to have the right of setoff provided in Section 11.1 in respect of its participating interest in amounts owing under the Loan Documents to the same extent as 65

if the amount of its participating interest were owing directly to it as a Lender under the Loan Documents, provided that each Lender shall retain the right of setoff provided in Section 11.1 with respect to the amount of participating interests sold to each Participant. The Lenders agree to share with each Participant, and each Participant, by exercising the right of setoff provided in Section 11.1, agrees to share with each Lender, any amount received pursuant to the exercise of its right of setoff, such amounts to be shared in accordance with Section 11.2 as if each Participant were a Lender. The Obligors further agree that each Participant shall be entitled to the benefits of Sections 3.1, 3.2, 3.4 and 3.5 to the same extent as if it were a Lender and had acquired its interest by assignment pursuant to Section 12.3, provided that (i) a Participant shall not be entitled to receive any greater payment under Section 3.1, 3.2 or 3.5 than the Lender who sold the participating interest to such Participant would have received had it retained such interest for its own account, unless the sale of such interest to such Participant is made with the prior written consent of the Borrower, and (ii) any Participant not incorporated under the laws of the United States of America or any State thereof agrees to comply with the provisions of Section 3.5 to the same extent as if it were a Lender. 12.3. Assignments. 12.3.1. Permitted Assignments. Any Lender may at any time assign to one or more banks or other entities ("Purchasers") all or any part of its rights and obligations under the Loan Documents. Such assignment shall be substantially in the form of Exhibit C or in such other form as may be agreed to by the parties thereto. Each such assignment with respect to a Purchaser which is not a Lender or an Affiliate of a Lender or an Approved Fund shall either be in an amount equal to the entire applicable Commitment and Loans of the assigning Lender or (unless each of the Borrower and the Agent otherwise consents) be in an aggregate amount not less than $5,000,000. The amount of the assignment shall be based on the Commitment or outstanding Loans (if the Commitment has been terminated) subject to the assignment, determined as of the date of such assignment or as of the "Trade Date," if the "Trade Date" is specified in the assignment. 12.3.2. Consents. The consent of the Borrower shall be required prior to an assignment becoming effective unless the Purchaser is a Lender, an Affiliate of a Lender or an Approved Fund, provided that the consent of the Borrower shall not be required if a Default has occurred and is continuing. The consent of the Agent shall be required prior to an assignment becoming effective unless the Purchaser is a Lender, an Affiliate of a Lender or an Approved Fund. Any consent required under this Section 12.3.2 shall not be unreasonably withheld or delayed. 12.3.3. Effect; Effective Date. Upon (i) delivery to the Agent of an assignment, together with any consents required by Sections 12.3.1 and 12.3.2, and (ii) payment of a $4,000 fee to the Agent for processing such assignment (unless such fee is waived by the Agent), such assignment shall become effective on the effective date specified in such assignment. The assignment shall contain a representation by the Purchaser to the effect that none of the consideration used to make the purchase of the Commitment and Loans under the applicable assignment agreement constitutes "plan assets" as defined under 66

ERISA and that the rights and interests of the Purchaser in and under the Loan Documents will not be "plan assets" under ERISA. On and after the effective date of such assignment, such Purchaser shall for all purposes be a Lender party to this Agreement and any other Loan Document executed by or on behalf of the Lenders and shall have all the rights and obligations of a Lender under the Loan Documents, to the same extent as if it were an original party thereto, and the transferor Lender shall be released with respect to the Commitment and Loans assigned to such Purchaser without any further consent or action by the Borrower, the Lenders or the Agent. In the case of an assignment covering all of the assigning Lender's rights and obligations under this Agreement, such Lender shall cease to be a Lender hereunder but shall continue to be entitled to the benefits of, and subject to, those provisions of this Agreement and the other Loan Documents which survive payment of the Obligations and termination of the applicable agreement. Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not comply with this Section 12.3 shall be treated for purposes of this Agreement as a sale by such Lender of a participation in such rights and obligations in accordance with Section 12.2. Upon the consummation of any assignment to a Purchaser pursuant to this Section 12.3.3, the transferor Lender, the Agent and the Borrower shall, if the transferor Lender or the Purchaser desires that its Loans be evidenced by Notes, make appropriate arrangements so that new Notes or, as appropriate, replacement Notes are issued to such transferor Lender and new Notes or, as appropriate, replacement Notes, are issued to such Purchaser, in each case in principal amounts reflecting their respective Commitments, as adjusted pursuant to such assignment. 12.3.4. Register. The Agent, acting solely for this purpose as an agent of the Borrower, shall maintain at one of its offices in Chicago, Illinois a copy of each Assignment and Assumption delivered to it and a register for the recordation of the names and addresses of the Lenders, and the Commitments of, and principal amounts of the Loans owing to, each Lender pursuant to the terms hereof from time to time (the "Register"). The entries in the Register shall be conclusive, and the Obligors, the Agent and the Lenders may treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Lender hereunder for all purposes of this Agreement, notwithstanding notice to the contrary. The Register shall be available for inspection by the Borrower and any Lender, at any reasonable time and from time to time upon reasonable prior notice. 12.4. Dissemination of Information. The Obligors authorize each Lender to disclose to any Participant or Purchaser or any other Person acquiring an interest in the Loan Documents by operation of law (each a "Transferee") and any prospective Transferee any and all information in such Lender's possession concerning the creditworthiness of the Parent Guarantor and its Subsidiaries, including without limitation any information contained in any Reports; provided that each Transferee and prospective Transferee agrees to be bound by Section 9.11 of this Agreement. 12.5. Tax Treatment. If any interest in any Loan Document is transferred to any Transferee which is not incorporated under the laws of the United States or any State thereof, the transferor Lender shall cause such Transferee, concurrently with the effectiveness of such transfer, to comply with the provisions of Section 3.5(iv). 67

ARTICLE XIII NOTICES 13.1. Notices. Except as otherwise permitted by Section 2.14 with respect to borrowing notices, all notices, requests and other communications to any party hereunder shall be in writing (including electronic transmission, facsimile transmission or similar writing) and shall be given to such party: (x) in the case of any Obligor or the Agent, at its address or facsimile number set forth on Schedule 7 hereto, (y) in the case of any Lender, at its address or facsimile number set forth on Schedule 7 hereto (in the case of Bank One) or in its administrative questionnaire (in the case of any other Lender) or (z) in the case of any party, at such other address or facsimile number as such party may hereafter specify for the purpose by notice to the Agent and the Borrower in accordance with the provisions of this Section 13.1. Each such notice, request or other communication shall be effective (i) if given by facsimile transmission, when transmitted to the facsimile number specified in this Section and confirmation of receipt is received, (ii) if given by mail, 72 hours after such communication is deposited in the mails with first class postage prepaid, addressed as aforesaid, or (iii) if given by any other means, when delivered (or, in the case of electronic transmission, received) at the address specified in this Section; provided that notices to the Agent under Article II shall not be effective until received. 13.2. Change of Address. Each Obligor, the Agent and any Lender may each change the address for service of notice upon it by a notice in writing to the other parties hereto. ARTICLE XIV COUNTERPARTS This Agreement may be executed in any number of counterparts, all of which taken together shall constitute one agreement, and any of the parties hereto may execute this Agreement by signing any such counterpart. This Agreement shall be effective when it has been executed by the Obligors, the Agent and the Lenders and each party has notified the Agent by facsimile transmission or telephone that it has taken such action. ARTICLE XV CHOICE OF LAW; CONSENT TO JURISDICTION; WAIVER OF JURY TRIAL 15.1. CHOICE OF LAW. THE LOAN DOCUMENTS (OTHER THAN THOSE CONTAINING A CONTRARY EXPRESS CHOICE OF LAW PROVISION) SHALL BE CONSTRUED IN ACCORDANCE WITH THE INTERNAL LAWS (INCLUDING, WITHOUT LIMITATION, 735 ILCS SECTION 105/5-1 ET SEQ, BUT OTHERWISE WITHOUT REGARD TO THE CONFLICT OF LAWS PROVISIONS) OF THE STATE OF ILLINOIS, BUT GIVING EFFECT TO FEDERAL LAWS APPLICABLE TO NATIONAL BANKS. 15.2. CONSENT TO JURISDICTION. THE OBLIGORS HEREBY IRREVOCABLY SUBMIT TO THE NON-EXCLUSIVE JURISDICTION OF ANY 68

UNITED STATES FEDERAL OR ILLINOIS STATE COURT SITTING IN CHICAGO, ILLINOIS IN ANY ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO ANY LOAN DOCUMENTS AND THE BORROWER HEREBY IRREVOCABLY AGREES THAT ALL CLAIMS IN RESPECT OF SUCH ACTION OR PROCEEDING MAY BE HEARD AND DETERMINED IN ANY SUCH COURT AND IRREVOCABLY WAIVES ANY OBJECTION IT MAY NOW OR HEREAFTER HAVE AS TO THE VENUE OF ANY SUCH SUIT, ACTION OR PROCEEDING BROUGHT IN SUCH A COURT OR THAT SUCH COURT IS AN INCONVENIENT FORUM. NOTHING HEREIN SHALL LIMIT THE RIGHT OF THE AGENT OR ANY LENDER TO BRING PROCEEDINGS AGAINST ANY OBLIGOR IN THE COURTS OF ANY OTHER JURISDICTION. ANY JUDICIAL PROCEEDING BY ANY OBLIGOR AGAINST THE AGENT OR ANY LENDER OR ANY AFFILIATE OF THE AGENT OR ANY LENDER INVOLVING, DIRECTLY OR INDIRECTLY, ANY MATTER IN ANY WAY ARISING OUT OF, RELATED TO, OR CONNECTED WITH ANY LOAN DOCUMENT SHALL BE BROUGHT ONLY IN A COURT IN CHICAGO, ILLINOIS. 15.3. WAIVER OF JURY TRIAL. EACH OBLIGOR, THE AGENT AND EACH LENDER HEREBY WAIVE TRIAL BY JURY IN ANY JUDICIAL PROCEEDING INVOLVING, DIRECTLY OR INDIRECTLY, ANY MATTER (WHETHER SOUNDING IN TORT, CONTRACT OR OTHERWISE) IN ANY WAY ARISING OUT OF, RELATED TO, OR CONNECTED WITH ANY LOAN DOCUMENT OR THE RELATIONSHIP ESTABLISHED THEREUNDER. 15.4. LIMITATION OF LIABILITY OF OWNER TRUSTEE. It is expressly understood and agreed by and among the parties hereto that, except as otherwise expressly provided herein or therein, each of this Loan Agreement and the other Loan Documents is executed by Wilmington Trust Company, not individually or personally but solely as Trustee under the Trust Agreement in the exercise of the power and authority conferred and vested in it as such Trustee, that each and all of the representations, undertakings and agreements herein or therein made on the part of the Trustee or the Borrower are intended not as personal representations, undertakings and agreements by Wilmington Trust Company, or for the purpose or with the intention of binding Wilmington Trust Company, personally, but are made and intended for the purpose of binding only the Trust Estate, that nothing herein contained shall be construed as creating any liability of Wilmington Trust Company, or any incorporator or any past, present or future subscriber to the capital stock of, or stockholder, officer or director of Wilmington Trust Company, to perform any covenant either express or implied contained herein or in the other Loan Documents to which the Trustee or the Borrower is a party, and that so far as Wilmington Trust Company is concerned, any Person shall look solely to the Trust Estate for the performance of any obligation hereunder or thereunder or under any of the instruments referred to herein or therein; provided, however, that nothing contained in this Section shall be construed to limit in scope or substance the general corporate liability of Wilmington Trust Company, expressly provided (i) to the Certificate Holders under the Trust Agreement, (ii) in respect of those representations, warranties, agreements and covenants of Wilmington Trust Company expressly set forth in Section 7(a) hereof or in any Loan Document to which it is a party or (iii) pursuant to the Trust Agreement, for the gross negligence or willful misconduct of Wilmington Trust Company or to exercise the same degree of care and skill as is customarily 69

SCHEDULE 9 DESCRIPTION OF PLATFORM PLANS AND SPECIFICATIONS The Gunnison spar production platform is a 98-foot diameter cylinder, approximately 549 feet in length, with a draft of about 499 feet and freeboard of 50 feet. It is a floating structure, which supports topsides with a capacity of 40,000 BOPD and 200 MMCFD. It is securely moored in place with a 9-leg mooring system consisting of wire and chain elements and anchor piles permanently installed in the sea floor. GUNNISON SPAR PRINCIPAL CHARACTERISTICS are shown in Table 1. The estimated time to design, construct, install and hook up the spar production facility is 24-27 months. Engineering design, which occupies the first 2 months of this period, was initiated during September 2001. Thus it is anticipated that the spar can be installed in August/September of 2003 with first production by January 2004. The upper portion of the spar hull consists of watertight compartments designed to withstand hydrostatic pressure which provide the buoyancy to support the structure. Double hull construction is used for 50 feet above and 20 feet below the waterline. The middle section of the hull is a truss structure constructed of tubular steel members. The bottom portion or keel of the hull contains the soft ballast tank. This tank provides the necessary buoyancy for the horizontal towout. Once installed the soft tank is filled with a slurry of magnetite (fixed ballast) to provide the necessary weight distribution for optimum stability of the spar. The square centerwell is 42 feet by 42 feet and runs through the length of the hull. Production risers are installed on 11-foot centers in the centerwell and are supported by individual cylindrical buoyancy modules called air cans, located within the production riser guide frames. These air cans include stem sections that protect the riser for the full length of the hull. The production risers consist of 9-5/8" diameter pipe from the seafloor to the buoyancy cans. They are secured to the wellhead with tieback connectors. In addition to providing for the production risers, the centerwell provides the space for the subsea risers and the export pipeline risers. The risers are brought through the keel of the hull and up through the truss and tanks via guides that are installed in the structure. Either flexible pipe or Steel Catenary Risers (SCR'S) will be installed. Current design configuration provides for risers as follows: 16" or 18" oil export line 16" or 18" gas export line 8 - 6" or 8" risers with 4 umbilicals 2 - 12" import risers or an 8" subsea pair with umbilical. Current plans call for the initial installation of the two export lines, four 6" risers and two umbilicals. The two 12" risers provide the capability for accepting future large volume production imports from others while the remaining four 6" or 8" risers will be used for tieback of nearby future subsea wells. S-IX-1

The hull supports a three-level deck. The top deck measures 112 feet by 159 feet and is designed to support a 1,500 HP workover rig. This rig will be used for completion and well workover activity. Any equipment installed on the top deck will have to be removed during rig activity. The mid-level Production Deck measure 127 feet by 162 feet while the lower level Cellar Deck measures 127 feet by 176 feet. These two lower decks contain all the equipment necessary to process well fluids to pipeline quality. The major production equipment have been designed and will be fabricated to sit atop the spar hull on the cellar and production decks. The equipment will consist of modular and skid mounted equipment as necessary to process the produced fluids. A Preliminary Gunnison Equipment List is attached as Table 2. The facility will include a 20-man permanent living quarters to house operations personnel and provide office space for workers and visiting personnel. The anticipated manning level at this time is approximately 13 individuals. The operational base is anticipated to be located in Galveston, Texas. During workover or construction activities, four 12-man temporary sleeper buildings may be added to the top deck to sustain 68 total people on board. Two 80-man survival craft are a permanent part of the production facility as mandated by the United States Coast Guard rules. An 8-man rescue boat and life rafts to accommodate 80 people are also included on the facility. The helideck is 52-feet square and rated for a large Bell ST214 helicopter with a take-off weight of 26,250 pounds including a 50% impact loading. Wellheads are at about the production deck level and are connected to the production manifolds with flexible jumper lines. The spar hull will be classed as a Floating Offshore Installation (FOI) by the American Bureau of Shipping (ABS). This classification process assures that the structural and mechanical systems are fit for their intended service. This is accomplished by ABS review of the design and inspection during the fabrication process. ABS and industry standards are used as the basis for the design and inspection. ABS will also function as the Certified Verification Agency (CVA) for the permits required by the Minerals Management Service (MMS) and US Coast Guard. The topsides will not be classed. Environmental criteria have been established for use in the design of the hull, mooring and riser systems. These criteria were developed from available industry and Joint Industry Project databases with the assistance of a consultant. The Platform includes the entire floating facility including the spar hull, topsides, quarters, machinery, equipment, production systems, flare, pedestal cranes, hoists, generators, pumps, compressors, control systems, appliances, furniture, spare and replacement parts and the complete mooring system including the suction piles installed in the sea floor. The Platform also includes the dry tree risers and associated jumpers beginning at the UWD-15 wellhead at the sea floor, but not including the subsea wellhead. S-IX-2

The Platform does not include the subsea oil and gas wells, the subsea wellheads, the subsea tiebacks, the workover rig, any import or export pipeline on the sea floor, the import risers below the keel joint receptacle, the steel catenary export risers below the keel joint hang-off basket, the subsea umbilicals below the topside umbilical termination assembly, and the flowlines below the flexible flowline hang-off assembly.

(ii) The definition of "Fixed Charge Coverage Ratio" set forth in Article I of the Agreement is hereby amended by deleting it in its entirety and substituting in lieu thereof the following new definition of "Fixed Charge Coverage Ratio":

"'Fixed Charge Coverage Ratio' means, with reference to the periods referred to below, on a consolidated basis for the Parent Guarantor and its Consolidated Subsidiaries, the ratio of Income from Operations to Interest Expense plus scheduled payments of principal plus the aggregate amount of cash dividends declared or paid on any preferred stock of the Parent Guarantor, for the three-month period ending March 31, 2002, the six-month period ending June 30, 2002, the nine-month period ending September 30, 2002, and thereafter on a rolling four-quarter basis, calculated as of the last day of each such period; provided, however, that for the three-month period being March 31, 2002 up to $3,000,000 of capitalized interest for the MARAD Debt shall not be included in calculating Interest Expense. For purposes of this definition, the interest expense on the liabilities described in Section 1(l) of Schedule 6 shall be excluded." (iii) The definition of "Interest Coverage Ratio" set forth in Article I of the Agreement is hereby amended by deleting it in its entirety and substituting in lieu thereof the following new definition of "Interest Coverage Ratio": "'Interest Coverage Ratio' means, on any day, the ratio of (a) EBIT to (b) Interest Expense plus the aggregate amount of cash dividends declared or paid on any preferred stock of the Parent Guarantor for the period of four consecutive fiscal quarters of the Parent Guarantor ending on the last day of the most recent fiscal quarter of the Parent Guarantor. For purposes of this definition, the interest expense on the liabilities described in Section 1(l) of Schedule 6 shall be excluded." (iv) Section 6.10 is hereby amended by deleting it in its entirety and substituting in lieu thereof the following new Section 6.10: "6.10. Dividends and Redemptions. The Parent Guarantor will not, nor will it permit any of its Subsidiaries to, declare or pay any dividends or make any distributions on its capital stock or redeem, repurchase or otherwise acquire or retire any of its capital stock at any time outstanding, except the following: (a) any Subsidiary of the Parent Guarantor may declare and pay dividends or make distributions to the Parent Guarantor or to a Wholly-Owned Subsidiary of the Parent Guarantor; (b) the Parent Guarantor may declare and pay dividends on the Approved Preferred Stock by issuing shares of its common stock; (c) the Parent Guarantor may redeem, repurchase, acquire or retire shares of the Approved Preferred Stock in exchange for shares of its common stock; and (d) the Parent Guarantor may declare and pay cash dividends on the Approved Preferred Stock provided that (i) both the declaration and Page 2

payment of any such dividend occur within the same fiscal quarter of the Parent Guarantor, (ii) no Default or Unmatured Default shall exist before or after giving effect to any such declaration for payment or be created as a result thereof, and (iii) the aggregate amount of cash dividends declared on the Approved Preferred Stock during any fiscal quarter of the Parent Guarantor does not exceed the maximum amount of cash dividends which could have been declared paid on the Approved Preferred Stock during the immediately preceding fiscal quarter of the Parent Guarantor (calculated without taking into account any of the cash dividends actually paid on the Approved Preferred Stock during such fiscal quarter) without violating either Section 11 or Section 12 of Schedule 6." (v) Section 6 of Schedule 6 is hereby amended by deleting it in its entirety and substituting in lieu thereof the following new Section 6: "Section 6. INTENTIONALLY DELETED." (vi) Section 8 of Schedule 6 is hereby amended by deleting it in its entirety and substituting in lieu thereof the following new Section 8: "Section 8. Agreements Restricting Liens and Distributions. The Parent Guarantor will not, nor will it permit any of its Subsidiaries to, enter into any agreement which (a) except with respect to specific Cal Dive Property encumbered to secure payment of Indebtedness related to such Cal Dive Property which encumbrance and Indebtedness are permitted under Section 1 and Section 2, respectively, of this Schedule IV, imposes restrictions greater than those under the Loan Documents upon the creation or assumption of any Lien upon such Cal Dive Property, revenues or assets, whether now owned or hereafter acquired, (b) limits the declaration or payment of dividends or any other distribution on any of the capital stock of, or any redemption, repurchase or other acquisition or retirement of any of the capital stock of, any of the Parent Guarantor's Subsidiaries, or (c) limits any loan or advance by any of the Parent Guarantor's Subsidiaries to the Parent Guarantor."
