-5- EXXON CORPORATION NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS 1. Basis Of Financial Statement Preparation These unaudited condensed consolidated financial statements should be read in the context of the consolidated financial statements and notes thereto filed with the Securities and Exchange Commission in the corporation's 1998 Annual Report on Form 10-K. In the opinion of the corporation, the information furnished herein reflects all known accruals and adjustments necessary for a fair statement of the results for the periods reported herein. All such adjustments are of a normal recurring nature. The corporation's exploration and production activities are accounted for under the "successful efforts" method. During the fourth quarter of 1998, Exxon de-consolidated the majority owned power companies in Hong Kong and China. These financial statements reflect the de-consolidation of these companies retroactive to January 1, 1998. These affiliates are now accounted for as equity companies in compliance with the Financial Accounting Standards Board Emerging Issues Task Force ruling on Issue No. 96-16, which requires equity company reporting for a majority owned affiliate when minority shareholders possess the right to participate in significant management decisions. Exxon's 1998 net income was not affected by the de-consolidation. The effect on Exxon's January 1, 1998 consolidated balance sheet related to the de-consolidation was a decrease in total assets of $3.6 billion, including $4.2 billion of net property, plant and equipment and a decrease in total liabilities of $3.6 billion, including $2.5 billion of short and long-term debt. The American Institute of Certified Public Accountants' Statement of Position 98-5, "Reporting on the Costs of Start-up Activities", was implemented in the fourth quarter of 1998, effective as of January 1, 1998. This statement requires that costs of start-up activities and organizational costs be expensed as incurred. The cumulative effect of this accounting change on years prior to 1998 was a charge of $70 million (net of $70 million income tax effect), or $0.03 per common share, that was reflected in the first quarter of 1998. This new accounting requirement did not have a significant effect on 1998 income before the cumulative effect of the accounting change. 2. Recently Issued Statements of Financial Accounting Standards In June 1998, the Financial Accounting Standards Board released Statement No. 133, "Accounting for Derivative Instruments and Hedging Activities Information." This statement establishes accounting and reporting standards for derivative instruments. The statement requires that an entity recognize all derivatives as either assets or liabilities in the financial statements and measure those instruments at fair value, and it defines the accounting for changes in the fair value of the derivatives depending on the intended use of the derivative. As amended by Financial Accounting Standards Board Statement No. 137 issued in June 1999, Statement No. 133 must be adopted beginning no later than 2001. No decision has been made as to whether the corporation will adopt this standard before 2001. Adoption of this statement is not expected to have a material effect upon the corporation's operations or financial condition.

-6- EXXON CORPORATION NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS 3. Litigation and Other Contingencies A number of lawsuits, including class actions, were brought in various courts against Exxon Corporation and certain of its subsidiaries relating to the accidental release of crude oil from the tanker Exxon Valdez in 1989. Essentially all of these lawsuits have now been resolved or are subject to appeal. On September 24, 1996, the United States District Court for the District of Alaska entered a judgment in the amount of $5.058 billion in the Exxon Valdez civil trial that began in May 1994. The District Court awarded approximately $19.6 million in compensatory damages to fisher plaintiffs, $38 million in prejudgment interest on the compensatory damages and $5 billion in punitive damages to a class composed of all persons and entities who asserted claims for punitive damages from the corporation as a result of the Exxon Valdez grounding. The District Court also ordered that these awards shall bear interest from and after entry of the judgment. The District Court stayed execution on the judgment pending appeal based on a $6.75 billion letter of credit posted by the corporation. Exxon has appealed the judgment. Exxon has also appealed the District Court's denial of its renewed motion for a new trial. The Ninth Circuit heard oral arguments on the appeals on May 3, 1999. The corporation continues to believe that the punitive damages in this case are unwarranted and that the judgment should be set aside or substantially reduced by the appellate courts. On January 29, 1997, a settlement agreement was concluded resolving all remaining matters between Exxon and various insurers arising from the Valdez accident. Under terms of this settlement, Exxon received $480 million. Final income statement recognition of this settlement continues to be deferred in view of uncertainty regarding the ultimate cost to the corporation of the Valdez accident. The ultimate cost to the corporation from the lawsuits arising from the Exxon Valdez grounding is not possible to predict and may not be resolved for a number of years. In each of the years 1998, 1997 and 1996, $70 million in payments were made under the October 8, 1991 civil agreement and consent decree with the U.S. and Alaska governments. These payments were charged against the provision that was previously established to cover the costs of the settlement. German and Dutch affiliated companies are the concessionaires of a natural gas field subject to a treaty between the governments of Germany and the Netherlands under which the gas reserves in an undefined border or common area were to be shared equally. Entitlement to the reserves was to be determined by calculating the amount of gas which could be recovered from the area. Based on the final reserve determination, the German affiliate received more gas than its entitlement. Arbitration proceedings, as provided in the agreements, were conducted to resolve issues concerning the compensation for the overlifted gas.

-7- EXXON CORPORATION NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS By final award, dated July 2, 1999, preceded by an interim award in 1996, an arbitral tribunal established the full amount of the compensation for the excess gas. This amount has now been paid. While this final arbitral ruling on compensation is important, other substantive matters remain outstanding, including recovery of royalties paid on such excess gas and the taxes payable on the final compensation amount. The net financial impact on the corporation of these items is not possible to predict at this time. However, the ultimate outcome is not expected to have a materially adverse effect upon the corporation's operations or financial condition. The U.S. Tax Court has decided the issue with respect to the pricing of crude oil purchased from Saudi Arabia for the years 1979-1981 in favor of the corporation. This decision is subject to appeal. Certain other issues for the years 1979-1988 remain pending before the Tax Court. The ultimate resolution of these issues is not expected to have a materially adverse effect upon the corporation's operations or financial condition. Claims for substantial amounts have been made against Exxon and certain of its consolidated subsidiaries in other pending lawsuits, the outcome of which is not expected to have a materially adverse effect upon the corporation's operations or financial condition. The corporation and certain of its consolidated subsidiaries are directly and indirectly contingently liable for amounts similar to those at the prior year-end relating to guarantees for notes, loans and performance under contracts, including guarantees of non-U.S. excise taxes and customs duties of other companies, entered into as a normal business practice, under reciprocal arrangements. Additionally, the corporation and its affiliates have numerous long-term sales and purchase commitments in their various business activities, all of which are expected to be fulfilled with no adverse consequences material to the corporation's operations or financial condition. The operations and earnings of the corporation and its affiliates throughout the world have been, and may in the future be, affected from time to time in varying degree by political developments and laws and regulations, such as forced divestiture of assets; restrictions on production, imports and exports; price controls; tax increases and retroactive tax claims; expropriation of property; cancellation of contract rights and environmental regulations. Both the likelihood of such occurrences and their overall effect upon the corporation vary greatly from country to country and are not predictable. 4. Nonowner Changes in Shareholders' Equity The total nonowner changes in shareholders' equity for the three months ended June 30, 1999 and 1998 were $922 million and $1,344 million, respectively. The total nonowner changes in shareholders' equity for the six months ended June 30, 1999 and 1998 were $1,267 million and $3,135 million, respectively. Total nonowner changes in shareholders' equity include net income and the change in the cumulative foreign exchange translation adjustment and minimum pension liability adjustment components of shareholders' equity.

-10- EXXON CORPORATION 7. Restructuring Charge In the first quarter of 1999 the company recorded a $120 million after-tax charge for the restructuring of Japanese refining and marketing operations in its wholly owned Esso Sekiyu K.K. and 50.1 percent owned General Sekiyu K.K. affiliates. The restructuring resulted in the reduction of approximately 700 administrative, financial, logistics and marketing service employee positions during the quarter. The Japanese affiliates recorded a combined charge of $216 million (before tax) to selling, general and administrative expenses for the employee related costs. Cash outlays of $140 million were charged against this provision through June 30, 1999. General Sekiyu also recorded a $211 million (before tax) charge to depreciation and depletion for the write-off of costs associated with the cancellation of a power plant project at the Kawasaki terminal.

On a per share basis, second quarter 1999 net income declined 25 percent to $0.49. Exxon's net income of $1.2 billion was down $415 million from the second quarter of 1998. Depressed refining margins and weaker natural gas prices drove the decline in earnings. Weaker chemical margins, lower copper and coal prices, and unfavorable foreign exchange effects also lowered earnings. This year's second quarter results benefited from higher crude oil prices, increased chemical sales volumes and reduced operating expenses in all segments. Although second quarter results declined, Exxon's absolute level of net income has remained healthy over the last two years despite very weak industry conditions. With the improvement in oil prices, second quarter net income increased 18 percent from the first quarter of 1999, in contrast to the seasonal earnings decline that we usually see from the first to the second quarter of each year.

-12- EXXON CORPORATION Second quarter crude oil prices recovered over $4 per barrel from the 20-year lows experienced in the first quarter and were up about $2 per barrel from the second quarter of last year. Natural gas prices were lower in the U.S. and were much lower in Europe reflecting the impact and lag of declining petroleum product reference prices and weaker local currencies. Overall, gas prices outside of North America were 16 percent lower than the prior year and were at their lowest level in over a decade. Liquids production declined from the second quarter of 1998. As crude prices increased, downstream earnings decreased substantially versus the same period last year, reflecting the inability to raise product prices as rapidly as crude prices increased. Refining margins in all major markets were depressed and international downstream earnings were also adversely affected by weaker marketing margins and a stronger U.S. dollar. Chemicals earnings were down slightly, as lower prices and higher feedstock costs depressed commodity margins. Chemicals earnings benefited from record second quarter sales volumes and lower operating expenses. Earnings from other operations were down slightly as lower copper and coal prices were largely offset by reduced operating expenses. During the quarter, Exxon continued its active investment program, spending $2.5 billion on capital and exploration projects. OTHER COMMENTS ON SECOND QUARTER COMPARISON Exploration and production earnings benefited from rising crude oil prices, averaging about $2 per barrel more than the second quarter of 1998. Natural gas prices were lower in the U.S. and were much lower in Europe. Exploration and producing expenses were reduced versus the prior year. Liquids production decreased to 1,512 kbd (thousand barrels per day) compared to 1,609 kbd in the second quarter of 1998, primarily due to natural field declines and lower liftings in Alaska. The decline was partly offset by production from new developments in the North Sea and Azerbaijan. Natural gas production of 5,542 mcfd (million cubic feet per day) was essentially unchanged from the prior year. Earnings from U.S. exploration and production were $269 million compared with $187 million last year. Outside the U.S., earnings from exploration and production were $500 million, versus $497 million in the second quarter of 1998. Petroleum product sales of 5,406 kbd were essentially even with last year's record second quarter. Downstream earnings declined due to a significant drop in worldwide refining margins. Downstream earnings outside the U.S. were also adversely affected by higher scheduled maintenance, lower marketing margins and unfavorable foreign exchange effects. In the U.S., refining and marketing earnings were $124 million, down $102 million from the prior year. Refining and marketing operations outside the U.S. earned $34 million, a decrease of $378 million from 1998. Chemicals earnings were $274 million compared with $295 million in the same quarter a year ago. Margins were compressed by lower commodity prices and higher feedstock costs. Prime product sales volumes of 4,455 kt (thousand metric tons) established a quarterly record.

-13- EXXON CORPORATION Earnings from other operations, including coal, minerals and power, totaled $85 million, compared to $103 million in the second quarter 1998. Both copper and international coal prices were lower. Corporate and financing expenses of $81 million compared with $100 million in the second quarter of last year, reflecting lower tax-related charges. During the second quarter of 1999, Exxon purchased 4.1 million shares of Exxon common stock for the treasury at a cost of $325 million, representing a continuation of purchases to offset shares issued in conjunction with the company's benefit plans and programs. Purchases are made in open market and negotiated transactions and may be discontinued at any time. As a consequence of the proposed merger of Exxon and Mobil, the repurchase program to reduce the number of Exxon shares outstanding was discontinued in December 1998. FIRST SIX MONTHS 1999 COMPARED WITH FIRST SIX MONTHS 1998 Net income was $2,225 million in the first half of 1999, a decrease of 35 percent from the $3,440 million earned in 1998. Net income for the first half of 1999 included a $120 million charge for the restructuring of Japanese operations, while the prior year period included a $70 million charge relating to an accounting change. Excluding non-recurring items, first half 1999 net income declined 33 percent to $2,345 million or $0.96 per share, compared to $3,510 million or $1.41 per share last year. Exploration and production earnings declined due to the significant drop in gas prices in the U.S. and Europe. Crude oil realizations were up slightly versus the first half of 1998. Liquids production of 1,539 kbd compared to 1,616 kbd in the first half of 1998, primarily due to natural field declines and steps to curtail marginal volumes in the low price environment of the first quarter. Partly offsetting this was increased production from new developments in the North Sea and Azerbaijan. With the anticipated start-up of two North Sea developments in the second half of the year, full year liquids production levels for 1999 should be similar to 1998. Worldwide natural gas production of 6,527 mcfd was up 145 mcfd from 1998 due to colder European weather. Exploration and producing expenses were reduced from prior year levels. Earnings from U.S. exploration and production operations for the first six months were $405 million, a decrease of $9 million from 1998. Outside the U.S., exploration and production earnings were $925 million, down $255 million from last year, largely due to lower gas prices. Petroleum product sales of 5,449 kbd increased 44 kbd over last year, principally due to volume growth in North America. Earnings from U.S. refining and marketing operations were $96 million, down $230 million from 1998, reflecting the significant deterioration in industry refining margins and higher planned maintenance activities. Outside the U.S., first half 1999 refining and marketing earnings, excluding non-recurring items, decreased $600 million to $308 million, driven by much lower refining margins, weaker marketing margins and higher planned maintenance activities. Chemicals earnings totaled $579 million in the first half of 1999 compared with $669 million last year. Industry commodity prices and margins have declined from last year's levels. Prime product sales volumes of 8,832 kt were a first half record and increased 3 percent from last year.

-14- EXXON CORPORATION Earnings from other operations totaled $182 million, a decrease of $10 million from the first half of 1998, reflecting depressed copper and coal prices, offset by reduced operating expenses. Corporate and financing expenses decreased $29 million to $150 million, reflecting lower tax-related charges. During the period, the company's operating segments continued to benefit from the impact of lower effective tax rates and the favorable resolution of tax- related issues. Net cash generation before financing activities was $1,669 million in the first six months of 1999 versus $2,781 million in the same period last year. Operating activities provided net cash of $5,040 million, a decrease of $804 million from the prior year, influenced by lower net income. Investing activities used net cash of $3,371 million or $308 million more than a year ago, reflecting a higher level of capital investment. Net cash used in financing activities was $1,793 million in the first six months of 1999 versus $4,108 million for the year-ago period, the decrease due to lower purchases of shares of Exxon common stock and an increase in the debt level in the current year versus a reduction in the debt level in the prior year period. During the first half of 1999, Exxon purchased 6.4 million shares of its common stock for the treasury at a cost of $495 million, representing a continuation of purchases to offset shares issued in conjunction with the Company's benefit plans and programs. Capital and exploration expenditures in this year's first half were $4,620 million versus $4,526 million a year ago. Total debt of $9.3 billion at June 30, 1999 increased $0.5 billion from year- end 1998. The corporation's debt to total capital ratio was 17.2 percent at the end of the second quarter of 1999, compared to 16.2 percent at year-end 1998. Over the twelve months ended June 30, 1999, return on average shareholders' equity was 12.0 percent. Return on average capital employed, which includes debt, was 10.2 percent over the same time period. Although the corporation issues long-term debt from time to time and maintains a revolving commercial paper program, internally generated funds cover the majority of its financial requirements. Litigation and other contingencies are discussed in note 3 to the unaudited condensed consolidated financial statements. There are no events or uncertainties known to management beyond those already included in reported financial information that would indicate a material change in future operating results or future financial condition. The corporation, as part of its ongoing asset management program, continues to evaluate its mix of assets for potential upgrade. Because of the ongoing nature of this program, dispositions will continue to be made from time to time which will result in either gains or losses.

-15- EXXON CORPORATION YEAR 2000 ISSUE The Year 2000 Issue is the result of computer programs being written using two digits rather than four to define a specific year. Absent corrective actions, a computer program that has date-sensitive software may recognize a date using "00" as the year 1900 rather than the year 2000. This could result in system failures or miscalculations causing disruptions to various activities and operations. The corporation initiated assessments in prior years to identify the work efforts required to assure that systems supporting the business successfully operate beyond the turn of the century. The scope of this work effort encompasses business information systems, infrastructure, and technical and field systems, including systems utilizing embedded technology, such as microcontrollers. The program places particular emphasis on mission critical systems, defined as those which could have a significant safety, environmental or financial impact, should Year 2000 issues arise. Plans for achieving Year 2000 compliance were finalized during 1997, and implementation work has been underway since then. The initial phases of this work, an inventory and assessment of potential problem areas, have been essentially completed. Modification and testing phases continue, with more than 95 percent of required system modifications to mission critical systems completed. Some work is continuing into 1999, including final testing of some systems and scheduled implementation of new systems with Year 2000 impacts. Attention has also been focused on compliance attainment efforts of vendors and others, including key system interfaces with customers and suppliers. Most key suppliers and business partners have been contacted for clarification of their Year 2000 plans and over three-fourths have confirmed that compliance plans are in place. Follow-up discussions are being held with key suppliers when necessary to gain satisfaction on their state of readiness. These reviews will continue through 1999. Testing of critical third party products and services is underway, including such areas as process control systems, credit card processing, banking transactions and telecommunications. Notwithstanding the substantive work efforts described above, the corporation could potentially experience disruptions to some mission critical operations or deliveries to customers as a result of Year 2000 issues, particularly in the first few weeks of the year 2000. Such disruptions could include impacts from potentially non-compliant systems utilized by suppliers, customers, government entities or others. Given the diverse nature of Exxon's operations, the varying state of readiness of different countries and suppliers, and the interdependence of Year 2000 impacts, the potential financial impact or liability associated with such disruptions cannot be reasonably estimated. Exxon operating sites around the world, including those in developing countries, are working with key suppliers in their respective countries to address Year 2000 issues. In addition, Year 2000 Business Contingency Guidelines are being used by all operating organizations and affiliates, and include specific reference to areas such as transportation, telecommunications and utility services. Existing site contingency plans are being updated in order to attempt to mitigate the extent of potential disruption to business operations. This work is essentially complete with refinement of contingency plans continuing through 1999.

-16- EXXON CORPORATION Through June 30, 1999, about $210 million of costs had been incurred in the corporation's efforts to achieve Year 2000 compliant systems. The total cost to the corporation of achieving Year 2000 compliant systems is currently estimated to be $225 to $250 million, primarily over the 1997-1999 timeframe, and is not expected to be a material incremental cost impacting Exxon's operations, financial condition or liquidity. FORWARD-LOOKING STATEMENTS Statements in this report regarding future events or conditions are forward- looking statements. Actual results, including projections of liquids production levels and the impact of the Year 2000 Issue, could differ materially due to, among other things, factors discussed in this report and in Item 1 of the corporation's most recent Annual Report on Form 10-K.
