-4- EXHIBIT 99.2 UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS The following unaudited pro forma condensed combined financial statements combine the historical consolidated balance sheets and statements of income of Exxon and Mobil giving effect to the merger using the pooling of interests method of accounting for a business combination. This information was derived from the audited financial statements of Exxon for the years 1998, 1997, and 1996 and its unaudited financial statements for the nine months ended September 30, 1999 and 1998 and from the audited financial statements of Mobil for the years 1998, 1997 and 1996 and its unaudited financial statements for the nine months ended September 30, 1999 and 1998. The information is only a summary and should be read in conjunction with the historical financial statements and related notes contained in the annual reports and other information filed with the SEC. The unaudited pro forma condensed combined statements of income for the years ended December 31, 1998, 1997 and 1996 and for the nine months ended September 30, 1999 and 1998 assume the merger was effected on January 1, 1996. The unaudited pro forma condensed combined balance sheet gives effect to the merger as if it had occurred on September 30, 1999. The accounting policies of Exxon and Mobil are substantially comparable. Consequently, no adjustments were made to the unaudited pro forma condensed combined financial statements to align the accounting policies of the combining companies. The unaudited pro forma combined financial information is for illustrative purposes only. The companies may have performed differently had they always been combined. The pro forma combined financial information may not be indicative of the historical results that would have been achieved had the companies always been combined or the future results that the merged companies will experience operating as a combined company.

-7- NOTES TO UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS Note 1. Basis of Presentation The unaudited pro forma condensed combined statements of income are based on the consolidated financial statements of Exxon and Mobil for the years ended December 31, 1998, 1997 and 1996 and for the nine months ended September 30, 1999 and 1998. The unaudited pro forma condensed combined balance sheet is based on the condensed consolidated financial statements of Exxon and Mobil at September 30, 1999. Exxon and Mobil consolidated financial statements are prepared in conformity with generally accepted accounting principles and require Exxon and Mobil management to make estimates that affect the reported amounts of assets, liabilities, revenues and expenses and the disclosure of contingent assets and liabilities. In the opinion of Exxon and Mobil, the unaudited pro forma condensed combined financial statements include all adjustments necessary to present fairly the results of the periods presented. Actual results are not expected to differ materially from these estimates. Note 2. Accounting Policies and Financial Statement Classifications The accounting policies of Exxon and Mobil are substantially comparable. Consequently, no adjustments were made to the unaudited pro forma condensed combined financial statements to align the accounting policies of the combining companies. Certain revenues, costs and other deductions in the consolidated statements of income for Exxon and Mobil have been reclassified to conform to the line item presentation in the pro forma condensed combined statements of income. Certain assets, liabilities and shareholders' equity balances in the consolidated balance sheets for Exxon and Mobil have been reclassified to conform to the line item presentation in the pro forma condensed combined balance sheet. Note 3. Pro Forma Earnings Per Share and Dividends Per Share The pro forma combined net income per common share is based on net income less preferred stock dividends and the weighted average number of outstanding common shares. Net income per common share-assuming dilution includes the dilutive effect of incentive program stock options and convertible preferred stock. The weighted average number of outstanding common shares has been adjusted to reflect the exchange ratio of 1.32015 shares of ExxonMobil common stock for each share of Mobil common stock. The pro forma combined dividends per share reflect the sum of the dividends paid by Exxon and Mobil divided by the number of shares that would have been outstanding for the periods, after adjusting the Mobil shares for the exchange ratio of 1.32015 shares of ExxonMobil common stock. Note 4. Intercompany Transactions Intercompany sales and purchase transactions have been eliminated in the unaudited pro forma condensed combined statements of income. Intercompany amounts receivable and payable have been eliminated in the unaudited pro forma condensed combined balance sheet. Note 5. Merger-Related and Integration-Related Expenses An additional liability for merger-related fees and expenses of approximately $100 million has been reflected in the unaudited pro forma condensed combined balance sheet as of September 30, 1999. These fees include SEC filing fees, fees and expenses of investment bankers, attorneys and accountants, and financial printing and other related charges. These charges are not reflected in the unaudited pro forma condensed combined statements of income or the pro forma combined per share data.

-8- NOTES TO UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS Estimated costs of approximately $2.5 billion ($1.5 billion after-tax) will be incurred for severance and other integration-related expenses, including the elimination of duplicate facilities and excess capacity, operational realignment and related workforce reductions. These expenditures are necessary to reduce costs and operate efficiently. The unaudited pro forma condensed combined financial statements reflect neither the impact of these charges nor the benefits from the expected synergies. The costs for severance and other integration-related expenses will be charged to operations in the periods in which the obligations are incurred. Note 6. Other Pro Forma Adjustments (A) A pro forma adjustment has been made to consolidate the accounts of certain refining, marketing and chemicals operations that are jointly controlled by the combining companies and which were accounted for by Exxon and Mobil as separate companies using the equity method. (B) A pro forma adjustment has been made to reflect the cancellation of Mobil common stock accounted for as treasury stock and the assumed issuance of approximately 1.0 billion shares of ExxonMobil common stock in exchange for all the outstanding Mobil common stock (based on the exchange ratio of 1.32015). The actual number of shares of ExxonMobil common stock issued in connection with the merger was on the number of shares of Mobil common stock issued and outstanding at the effective time. Note 7. Required Regulatory Asset Divestments As a condition for approval of the merger by the U.S. Federal Trade Commission and the European Commission, Exxon and Mobil must divest specified assets, including certain refining and marketing assets and pipeline interests in the U.S.; certain refining and marketing and natural gas distribution assets in Europe; and turbine oil assets worldwide. The carrying amount of the required regulatory asset divestments on the balance sheet is approximately $3 billion as of September 30, 1999, essentially all of which is reported as investments and advances and property, plant and equipment. The company expects the assets to be sold in the year 2000 and to realize proceeds of approximately $4-5 billion. A pro forma adjustment has been made to eliminate the estimated earnings for the required regulatory asset divestments in the unaudited pro forma condensed combined statements of income for the year ended December 31, 1998 and for the nine months ended September 30, 1999 and 1998. These adjustments assume the divestments occurred on January 1, 1998. The unaudited pro forma condensed combined statements of income do not reflect gains that may result from the required regulatory asset divestments.
