NOTES TO UNAUDITED PRO FORMA CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (in millions) Note 1: Basis of Presentation. The unaudited pro forma condensed consolidated balance sheet is based on the unaudited consolidated balance sheets of Amerada Hess Corporation (the Corporation) and Triton Energy Limited (Triton) at June 30, 2001. The unaudited pro forma condensed consolidated statements of income are based on the unaudited statements of income for the six-months ended June 30, 2001 and the audited statements of income for the year ended December 31, 2000 of the Corporation and Triton. The Corporation's and Triton's consolidated financial statements are prepared in conformity with generally accepted accounting principles and require estimates that affect the reported amounts of assets, liabilities, revenues and expenses and the disclosure of contingent assets and liabilities. The Corporation will account for the acquisition of Triton using the accounting standards established in Statement of Financial Accounting Standard Nos. 141, Business Combinations, and 142, Goodwill and Other Intangible Assets. FAS 141 requires use of the purchase method of accounting for business combinations. FAS 142 requires that goodwill not be amortized and that goodwill be reviewed for impairment at least annually. The unaudited pro forma financial statements are only illustrative. They are based on assumptions and do not purport to be indicative of the results of operations or the financial position that would have actually occurred if the combination had been consummated on the dates indicated or that may be expected in the future. Note 2: Accounting Policies and Financial Statement Classifications. The Corporation uses the successful efforts method of accounting for oil and gas exploration and production; Triton used the full cost method. The pro forma adjustments include entries that conform Triton's accounting to the successful efforts method. All other accounting policies of the combining companies are substantially comparable. Certain items in the consolidated financial statements of Triton have been reclassified to conform to the line-item presentation in the pro forma financial statements. 5

Note 3: Pro Forma Adjustments. The unaudited pro forma financial statements reflect the merger using the purchase method of accounting. Amerada Hess Corporation cash used at closing $ 190 Borrowings, mainly at fixed rates 2,623 Transaction costs accrued 30 ------ 2,843 ------ Allocation of purchase price Fair value of assets acquired 3,301 Less fair value of liabilities assumed 1,423 ------ 1,878 ------ Excess of purchase price over fair value of net assets acquired (goodwill) $ 965 ====== The following pro forma adjustments reflect estimates and assumptions made by the Corporation: Pro Forma Balance Sheet (a) To record Amerada Hess Corporation cash paid, debt incurred and transaction costs accrued to acquire Triton. (b) To record the exercise of outstanding Triton stock options at the closing date. (c) To reclassify and conform line item presentation. (d) To record assets acquired and liabilities assumed at fair market value, including property, plant and equipment, investment in an oil and gas corporate joint venture and debt. (e) To record goodwill (excess of purchase price over fair value of net assets acquired). (f) To accrue Triton transaction costs related to the acquisition. (g) To record additional deferred income taxes resulting from acquisition. (h) To record liability for purchase of remaining shares (approximately 2.7% of outstanding Triton stock). (i) To eliminate Triton's stockholder equity accounts. Pro Forma Income Statement (j) To record adjustments to convert Triton to the successful efforts method of accounting for oil and gas operations and to reclassify and conform line item presentation. (k) To record interest expense on debt used to finance the acquisition. The interest rate is approximately 6.2%. (l) To record capitalized interest on projects under development. (m) To record additional depreciation, depletion and amortization based on the units of production method. (n) To record income tax effects on the pro forma adjustments based on estimated tax rates. 6

Note 4: Pro Forma Earnings Per Share. The pro forma income per share is based on pro forma income and the weighted average number of outstanding common shares. Diluted income per share includes the effect of dilutive securities, including stock options. Note 5: Cost Savings and Integration Related Expenses. The unaudited pro forma financial statements do not reflect any anticipated cost savings or efficiencies resulting from combining operations. (c) Exhibits.
