                    [FINANCIAL STATEMENTS FOR THE YEAR 2001]

To the Members
of the G.I.E. Mar Profundo Girassol:

We have audited the accompanying balance sheets of Mar Profundo Girassol as of
December 31, 2001 and December 31, 2000 and the related statements of income and
cash flows for each of the two years in the period ended December 31, 2001, all
expressed in Euros. These financial statements are the responsibility of the
company's management. Our responsibility is to express an opinion on this
financial statements based on our audits.

We conducted our audits in accordance with generally accepted auditing standards
in France and in the United States of America. 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
audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in
all material respects, the financial position of Mar Profundo Girassol as of
December 31, 2001 and December 31, 2000, and the results of its operations and
its cash flows for each of the two years in the period ended December 31, 2001
in conformity with generally accepted accounting principles in France.

Accounting practices used by the company in preparing the accompanying financial
statements conform with generally accepted accounting principles in France, but
do not conform in certain respects with accounting principles generally accepted
in the United States of America ("U.S. GAAP"). A description of these
differences and a complete reconciliation of net income to U.S. GAAP is set
forth in Note VIII.

NOTE I - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
--------------------------------------------------------------------------------

1.   FINANCIAL STATEMENTS PRESENTATION

     Financial statements are presented in Euros in compliance with generally
     accepted French accounting principles. These accounting principles have not
     changed since the incorporation of the G.I.E. Mar Profundo Girassol. The
     accounting period is : January 1st to December 31st.

2. USE OF ESTIMATES:

     In conformity with generally accepted accounting principles in France, the
     preparation of financial statements requires management to make estimates
     and assumptions based on current information and expectations. These may
     affect the amounts reported in financial statements and accompanying notes.
     The actual final results may differ from these estimates which may then
     impact subsequent financial statements.

3.   FOREIGN CURRENCY TRANSACTIONS

     A substantial portion of Mar Profundo Girassol's revenue is denominated in
     US Dollars. However, some of Mar Profundo Girassol's costs are denominated
     in other currencies, particularly in Euro.

     In order to shield Mar Profundo Girassol from future currency exchange rate
     variations, its policy is to hedge future forecasted outflows against
     future forecasted inflows using forward sales contracts. This applies only
     to unbalanced currency positions. Thus, US Dollar versus Euro forward sales
     contracts are settled only for the portion of US Dollar revenue that
     exceeds US Dollar expenditure or vice versa.

     Mar Profundo Girassol's exchange position is updated on a regular basis
     using all information available such as actual and forecasted sales and
     expenses, budget variations, management's best estimate, etc... Major
     variations in the use of a currency different from the currency initially
     forecasted result in an appropriate adjustment of the forward currency
     exchange contracts.

     It is not Mar Profundo Girassol's intent to hold derivative financial
     instruments for speculative purpose.

     Based on the forward exchange rates for all the forward currency exchange
     contracts, Mar Profundo Girassol determines an average exchange rate for
     each currency against Euro, in particular for US Dollars. Hedged
     transactions denominated in currencies other than Euro are recorded using
     the average exchange rate as described above. All US Dollar denominated
     transactions are recorded on a pre-determinated rate based on the forward
     exchange contracts as explained above. A variation in the currency position
     that impacts currency hedging, such as delays in cash collection or change
     in the currency of a forecasted cash-flows results in costs because of the
     mismatch. This is immediately evaluated for both current and subsequent
     impacts and reflected in the accounts in proportion of the overall progress
     of the contract.

ALL AMOUNTS ARE PRESENTED IN THOUSANDS OF EUROS UNLESS STATED OTHERWISE.

4.   INTANGIBLE AND TANGIBLE ASSETS

     INTANGIBLE ASSETS

     These consist of the software for the project. Software is valued at its
     acquisition cost and amortized on a straight-line basis over a period of
     one year. This has been fully amortized as of December 31, 1999.

     TANGIBLE ASSETS

     Tangible assets are recorded at acquisition cost and depreciated on the
     straight line method over 3 years.

     LONG TERM INVESTMENTS

     These consist of deposits associated with operating lease contracts and
     are valued at their historical cost. They are reversed when the leasing
     contract is terminated and the deposit is reimbursed.

5.   CONTRACT AND REVENUE RECOGNITION

     Contract revenues and related costs are recognized on the percentage of
     completion method, based on total project costs incurred to date, over the
     estimated total costs of contract at completion. Claims for extra-work or
     change in scope of work may be included in contract revenues when
     collection is probable.

     Contract price and cost estimates are reviewed periodically as the works
     progress and adjustments proportionate to the percentage of completion are
     reflected in the margin. Billings that exceed revenues recognized under
     percentage of completion are recorded as deferred revenue. Revenues
     recognized under percentage of completion method that exceed billings are
     booked as unbilled receivable.

     General and administrative costs supported by the members of the G.I.E are
     not charged to Mar Profundo Girassol.

6.   CASH AND CASH EQUIVALENTS

     Cash equivalents consist of highly liquid investments (marketable
     securities) with original maturity date of three months or less.
     Marketable securities are accounted for at their historical value and
     gains are recorded as financial income when sold.

7.   INCOME TAXES

     As a G.I.E, Mar Profundo Girassol shares its earnings between members in
     proportion to equity interest.

     As a consequence and in application of French fiscal and corporate laws,
     earnings of Mar Profundo Girassol taxable in France are subject to French
     income tax at the level of the members.

     Corporate income tax borne by Mar Profundo Girassol for its non French
     earnings are recognized, up to the percentage of completion of the project,
     in Mar Profundo Girassol accounts.

     personnel engaged on the project are either employees of a G.I.E. member or
     subcontracted. Any retirements benefits provisions, when necessary, are
     accounted by these external companies.

NOTE VIII - SIGNIFICANT DIFFERENCES BETWEEN ACCOUNTING PRINCIPLES FOLLOWED BY
            THE COMPANY AND THE US GAAP
--------------------------------------------------------------------------------

     The accompanying financial statements have been prepared in accordance with
     French GAAP, which differ in some respects from the accounting principles
     generally accepted in the United States of America ("US GAAP").

     The only significant difference that impacts the net equity and the net
     income of the Company corresponds to the accounting of foreign currency
     transactions in relation with hedging policy, as described hereafter.

1.   DESCRIPTION OF THE SIGNIFICANT DIFFERENCE BETWEEN ACCOUNTING PRINCIPLES
     FOLLOWED BY MAR PROFUNDO GIRASSOL AND THE US GAAP

     FRENCH GAAP ACCOUNTING PRINCIPLES RELATED TO FOREIGN CURRENCY TRANSACTIONS

     Under French GAAP, as disclosed in Note I.3 to the financial statements of
     Mar Profundo Girassol, hedged foreign currency transactions are recorded
     using the average guaranteed exchange rate resulting from the forward
     exchange contracts used as hedges, which includes the discount or premiums
     from those various contracts. Discount or premiums resulting from further
     rollovers of these contracts are recorded in proportion to the percentage
     of completion of the project.

     US GAAP ACCOUNTING PRINCIPLES RELATED TO FOREIGN CURRENCY TRANSACTIONS

     FOR THE YEAR 2000

     Under US GAAP, transactions denominated in foreign currencies are recorded
     using the exchange rate prevailing at the date of the transaction, except
     for the portion being hedged which is recorded using the spot rate of the
     forward exchange contract designated as a hedge. Discounts of premiums of
     the forward exchange contract are recorded over the period covered by the
     hedge.

ALL AMOUNTS ARE PRESENTED IN THOUSANDS OF EUROS UNLESS STATED OTHERWISE.

     At year-end, cash, receivables and payables to be received in foreign
     currency, are translated at year-end exchange rates, the translation
     difference is recorded in net earnings except for the portion being hedged
     which is deferred.

     FOR THE YEAR 2001

     For US GAAP reconciliation purposes, the Company has adopted as of January
     1, 2001, Statement of Financial Accounting Standards No. 133, Accounting
     for Derivative Instruments and Hedging Activities issued by the Financial
     Accounting Standards Board (FASB) in June 1998. In June 1999, the FASB
     issued Statement No. 137, Accounting for Derivative Instruments and Hedging
     Activities - Deferral of the Effective Date of FASB Statement No. 133. In
     June 2000, the FASB issued Statement 138, Accounting for Certain Derivative
     Instruments and Certain Hedging Activities, an amendment of FASB Statement
     No. 133. Statement 133, as amended, establishes accounting and reporting
     standards requiring that every derivative instrument (including certain
     derivative instruments embedded in other contracts) be recorded in the
     balance sheet as either an asset or liability measured at its fair value.
     The Statement requires that changes in the derivative instrument's fair
     value be recognized currently in earnings unless specific hedge accounting
     criteria are met. Special accounting for qualifying hedges allows a
     derivative instrument's gains and losses to offset related results on the
     hedged item in the income statement, to the extent effective, and requires
     that a company must formally document, designate, and assess the
     effectiveness of transactions that receive hedge accounting.

     Cash inflows generated by the sale contract with Elf Exploration Angola are
     denominated in U.S. Dollars, and are, as mentioned in note I.3 used to
     cover cash outflows denominated in the same currency. Additionally, the
     Company uses foreign currency forwards to hedge the foreign currency risks
     related to certain cash outflows not denominated in USD, and to finally
     exchange U.S dollars in its functional currency.

     As of January 1, 2001, the Company identified the foreign currency
     component of its sale contract as an embedded foreign exchange derivative.
     A portion of each monthly USD cash inflows generated according to the
     provisions of the sale contract was designated under SFAS 133 either:

     1.   as a fair value hedge of recognized liabilities and firm purchase
          commitments in USD or a cash-flow hedge of anticipated transactions
          denominated in such currency,

     2.   or, if associated with forward exchange contracts, as a fair value
          hedge of recognized liabilities and firm purchase commitments in
          currencies others than USD or Euros or a cash-flow hedge of
          anticipated transactions denominated in such currencies.

     All residual USD cash inflows were converted in Euro using forward exchange
     contracts. Such hedge relationship is considered as a natural hedge under
     SFAS 133.

     As of December 31, 2001, due to the percentage of completion of the
     contract with Elf Exploration Angola almost all anticipated inflows and
     outflows have been invoiced, and/or accrued for in the balance sheet. All
     amounts recorded in OCI as of January 1, 2001 (MEUR 2,3) have been
     reclassified in earnings over the period (symmetrically with the hedged
     cash flows). As of December 31, 2001 all hedging relationships are natural
     hedges consisting of foreign currency receivables or payables, residual
     embedded derivative and hedging forward contracts.

<Page>

ALL AMOUNTS ARE PRESENTED IN THOUSANDS OF EUROS UNLESS STATED OTHERWISE.

     Under French GAAP, all foreign currency transactions are recorded based on
     the average hedge rate and the derivative instruments are not recognized.
     Under US GAAP all revenues and expenses denominated in foreign currencies
     should be recorded using the exchange rate prevailing at the date of the
     transaction, except for those from which embedded derivatives were
     bifurcated which are recorded at the forward exchange rates prevailing as
     of the dates the contracts were signed. For US GAAP reconciliation
     purposes, all revenues and expenses were revalued accordingly which
     resulted in a reclassification of MEUR 33,8 from operating profit to
     financial profit. In addition, all receivables and payables were
     re-measured at closing spot rate and all outstanding derivatives (either
     embedded or freestanding) were recognized in the balance sheet. This
     adjustment resulted in a MEUR 3,3 net impact in earnings.

     Under French GAAP, gains and losses arising from the disposal of fixed
     assets are classified as extraordinary income. Under the US GAAP, such
     items would be a component of operating income/(expense). This
     difference would adjust operating income under US GAAP to the following:

         The net income of French "G.I.E." is immediately shared proportionately
