5 SCHEDULE A CAL DIVE INTERNATIONAL, INC. AND SUBSIDIARIES STATEMENT OF COMBINED REVENUES AND DIRECT OPERATING EXPENSES OF THE OIL AND GAS PROPERTY PURCHASED FROM SHELL OIL COMPANY (IN THOUSANDS)

Six Months For The Years Ended June 30, Ended December 31, 2002 2001 2001 2000 ---------------------------------------------------------------- (unaudited) Revenues ............................................ $ 14,701 $ 19,284 $ 32,621 $33,778 Direct operating expenses.............................. 3,252 5,775 8,054 6,426 ------------- -------------- ------------ ------------- Excess of revenues over direct operating expenses...... $11,449 $13,509 $24,567 $27,352 ============= ============== ============ ============= The accompanying notes are an integral part of this financial statement.

6 CAL DIVE INTERNATIONAL, INC. AND SUBSIDIARIES NOTES TO STATEMENT OF COMBINED REVENUES AND DIRECT OPERATING EXPENSES OF THE OIL AND GAS PROPERTY PURCHASED FROM SHELL OIL COMPANY (1) THE PROPERTY On August 30, 2002, Energy Resource Technology, Inc. ("ERT"), a wholly owned subsidiary of Cal Dive International, Inc. ("Cal Dive") acquired a 74.8% working interest in the South Marsh Island field from certain indirect subsidiaries of Shell Oil Company ("Shell"). This field ("SMI 130" or "the Acquisition") consists of two blocks: SMI 130 and SMI 131. ERT paid $10.3 million in cash and assumed Shell's pro-rata share of the related decommissioning liability. SMI 130 is located in approximately 215 feet of water, with approximately 155 wells on five 8-pile platforms. (2) BASIS FOR PRESENTATION The statement of combined revenues and direct operating expenses has been derived from Shell's historical financial records and is prepared on the accrual basis of accounting. Revenues and direct operating expenses as set forth in the accompanying statement include revenues from oil and gas production, net of royalties, and associated direct operating expenses related to the net revenue interest and net working interest, respectively. These revenues and expenses in SMI 130 represent ERT's acquired interest in SMI 130. During the periods presented, SMI 130 was not accounted for or operated as a separate division by Shell. Accordingly, full separate financial statements prepared in accordance with generally accepted accounting principles do not exist and are not practicable to obtain in these circumstances. This statement varies from an income statement in that it does not show certain expenses, which were incurred in connection with the ownership of SMI 130, such as general and administrative expenses, and income taxes. These costs were not separately allocated to SMI 130 in the Shell historical financial records and any pro forma allocation would be both time consuming and expensive and would not be a reliable estimate of what these costs would actually have been had SMI 130 been operated historically as a stand alone entity. In addition, these allocations, if made using historical Shell general and administrative structures and tax burdens, would not produce allocations that would be indicative of the historical performance of SMI 130 had they been assets of ERT, due to the greatly varying size, structure, and operations between ERT and Shell. This statement also does not include provisions for depreciation, depletion and amortization as such amounts would not be indicative of future costs and of those costs which would be incurred by ERT upon allocation of the purchase price. Accordingly, the financial statement and other information presented are not indicative of the financial condition or results of operations of SMI 130 going forward due to the changes in the business and the omission of various operating expenses. For the same reason, primarily the lack of segregated or easily obtainable reliable data on asset values and related liabilities, a balance sheet is not presented for SMI 130. At the end of the economic life of these fields, certain restoration and abandonment costs will be incurred by the respective owners of these fields. No accrual for these costs is included in the direct operating expenses. (3) RELATED PARTY TRANSACTIONS A portion of SMI 130's crude oil production was purchased by affiliates of Shell at market prices. Revenues in the accompanying statements include (in thousands) $10,818 and $5,380 for the six month periods ended June 30, 2002 and 2001, respectively, and $13,693 and $-0- for the years ended December 31, 2001 and 2000, respectively, related to such transactions. (4) COMMITMENTS AND CONTINGENCIES Pursuant to the terms of the Asset Purchase Agreements, Shell is obligated for any claims, litigation or disputes pending as of the effective date of July 1, 2002 or any matters arising in connection with ownership of SMI 130 prior to the effective date.

7 CAL DIVE INTERNATIONAL, INC. AND SUBSIDIARIES SUPPLEMENTAL OIL AND GAS INFORMATION OF THE OIL AND GAS PROPERTY PURCHASED FROM SHELL OIL COMPANY (UNAUDITED) OIL AND GAS RESERVE INFORMATION There are numerous uncertainties inherent in estimating quantities of proved reserves and projecting future rates of production. The following Cal Dive reserve data related to SMI 130 represent estimates only and should not be construed as being exact. The reliability of these estimates at any point in time depends on both the quality and quantity of the technical and economic data, the performance of the reservoirs, as well as extensive engineering judgment. Consequently, reserve estimates are subject to revision as additional data becomes available during the producing life of a reservoir. The evolution of technology may also result in the application of improved recovery techniques such as supplemental or enhanced recovery projects, which have the potential to increase reserves beyond those currently envisioned. Estimates of proved reserves are derived from quantities of crude oil and natural gas that geological and engineering data demonstrate with reasonable certainty to be recoverable in future years from known reservoirs under existing operating and economic conditions and rely upon a production plan and strategy.

8 STANDARDIZED MEASURE OF DISCOUNTED FUTURE NET CASH FLOWS RELATIING TO PROVED OIL AND GAS RESERVES The following disclosures concerning the standardized measure of future cash flows from proved oil and gas reserves are presented in accordance with the Statement of Financial Accounting Standards No. 69, Disclosures about Oil and Gas Producing Activities ("FAS 69"). As prescribed by FAS 69, the amounts shown are based on prices and costs at the end of each period and a 10 percent annual discount factor. Future cash flows are computed by applying fiscal year-end prices of natural gas and oil to year-end quantities of proved natural gas and oil reserves. Future operating expenses and development costs are computed primarily by Cal Dive's internal petroleum engineers by estimating the expenditures to be incurred in developing and producing the Acquisition's proved natural gas and oil reserves at the end of the year, based on year end costs and assuming continuation of existing economic conditions. Future income taxes are based on currently enacted statutory rates. The standardized measure of discounted future net cash flows is not intended to represent the replacement costs or fair value of SMI 130 natural gas and oil properties. An estimate of fair value would take into account, among other things, anticipated future changes in prices and costs, and a discount factor more representative of the time value of money and the risks inherent in reserve estimates of natural gas and oil producing operations. The Standardized Measure of Discounted Future Net Cash Flows relating to Proved Oil and Gas Reserves attributed to the Acquisition is as follows:

As of December 31, 2001 2000 --------------------- ------------------- Future cash inflows..................................................... $79,278 $192,908 Future operating expenses............................................... (35,829) (50,433) Future development and abandonment costs................................ (26,945) (26,945) Future income tax expense...............................................

15 CAL DIVE INTERNATIONAL, INC. AND SUBSIDIARIES PRO FORMA SUPPLEMENTAL OIL AND GAS DISCLOSURES - (CONTINUED) (UNAUDITED) The following is a summary of pro forma standardized measure of discounted future net cash flows from proved oil and gas reserves of Cal Dive as of December 31, 2001, net of income tax expense and includes the effects of the Acquisition. Future cash flows are computed by applying fiscal year-end prices of natural gas and oil to year-end quantities of proved natural gas and oil reserves. Future operating expenses and development costs are computed primarily by the Company's internal petroleum engineers by estimating the expenditures to be incurred in developing and producing the Acquisition's proved natural gas and oil reserves at the end of the year, based on year end costs and assuming continuation of existing economic conditions. Future income taxes are based on currently enacted statutory rates. The information should be viewed only as a form of standardized disclosure concerning possible future cash flows that would result under the assumptions used but should not be viewed as indicative of fair market value nor be considered indicative of any trends. Reference should be made to Cal Dive's financial statements for the fiscal year-ended December 31, 2001, and the Statement of Combined Revenues and Direct Operating Expenses of the Oil and Gas Property Purchased from Shell Oil Company included herein as Schedule A, for a discussion of the assumptions used in preparing the information presented.
