                                 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.

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 1999, 1998 and 1997, $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, but the Dutch affiliate is
    seeking to have the award set aside. 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 September 30, 1999 and 1998 were $2,059 million and $1,978 million,
    respectively. The total nonowner changes in shareholders' equity for the
    nine months ended September 30, 1999 and 1998 were $3,326 million and
    $5,113 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.

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. Substantially
    all cash expenditures anticipated in the restructuring provision have been
    paid as of September 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.

THIRD QUARTER 1999 COMPARED WITH THIRD QUARTER 1998

Exxon Corporation estimated third quarter 1999 net income of $1,500 million, up
7 percent from $1,400 million in the third quarter of 1998. On a per share
basis, quarterly net income was $0.61 per share compared to $0.58 per share in
last year's third quarter.

Exxon's net income of $1.5 billion increased $100 million from the third
quarter of 1998. The improvement was driven by higher crude prices, which were
up about $8 per barrel on average. Upstream earnings more than doubled compared
to last year's third quarter and represented the highest third quarter upstream
results in 15 years. Record chemicals sales volumes and reduced operating
expenses across the segments also benefited earnings. However, depressed
downstream margins in all geographic areas, weaker chemicals margins and lower
coal prices continued to negatively affect total results. Unfavorable foreign
exchange effects also lowered earnings. With the improvement in oil prices,
third quarter results exceeded the second quarter of 1999 by $295 million or 24
percent, in contrast to the seasonal earnings decline normally seen from the
second to the third quarter of each year.



                                  -12-





                                 EXXON CORPORATION


Third quarter crude oil prices were up about $5 per barrel from the second
quarter of this year. U.S. gas prices also improved almost $0.50 per kcf
(thousand cubic feet) from the second quarter. However, natural gas prices were
still depressed in Europe as the impact of rising crude and petroleum product
reference prices have not yet been reflected in contractual prices. As crude
prices increased rapidly during the quarter, downstream earnings decreased
substantially versus the same period last year, reflecting the inability to
raise product prices in line with rising crude prices. Downstream margins in
all markets were depressed. International downstream earnings were also
adversely affected by foreign exchange effects. As a result of these factors,
third quarter downstream earnings, excluding non-recurring items, were the
lowest quarterly results in over a decade. Chemicals earnings were up slightly,
as record quarterly sales volumes and lower operating expenses offset the
impact of higher feedstock costs which depressed margins. Earnings from other
operations also improved slightly due to higher copper prices and volumes and
lower operating expenses.

During the quarter, Exxon continued its active investment program, spending
nearly $2.0 billion on capital and exploration projects.

OTHER COMMENTS ON THIRD QUARTER COMPARISON

Exploration and production earnings benefited from rising crude oil prices,
which averaged about $8 per barrel more than the third quarter of 1998. Natural
gas prices were higher in the U.S., but were lower in Europe. Exploration and
producing expenses were reduced versus the prior year.

Liquids production decreased to 1,514 kbd (thousand barrels per day) compared
to 1,553 kbd in the third quarter of 1998, primarily due to lower liftings in
Alaska, Malaysia and Canada. The decline was partly offset by production from
new developments in the North Sea, the Gulf of Mexico and Azerbaijan. Fourth
quarter production is expected to increase due to the start-up of new
developments in Norway. Production from the Balder field began at the end of
September and the Jotun development started up at the end of October. Third
quarter natural gas production of 5,078 mcfd (million cubic feet per day) was
down 129 mcfd from the prior year.

Earnings from U.S. exploration and production were $451 million, an increase of
$240 million from last year. Outside the U.S., earnings from exploration and
production were $563 million, an increase of $289 million from the third
quarter of 1998.

Petroleum product sales of 5,431 kbd equaled last year's record third quarter
results. Downstream earnings declined as petroleum product prices were not
able to keep up with the steep increase in crude costs during the quarter.
Downstream earnings outside the U.S. were also adversely affected by
unfavorable foreign exchange effects.

In the U.S., refining and marketing earnings were $118 million, down $24
million from the prior year. Refining and marketing operations outside the U.S.
earned $19 million, a decrease of $420 million from 1998.

                                 EXXON CORPORATION

Chemicals earnings were $303 million compared with $301 million in the same
quarter a year ago. Margins were compressed as feedstock costs increased faster
than product prices. Prime product sales volumes of 4,596 kt (thousand metric
tons) established a quarterly record and were 6 percent higher than the same
period a year ago. Chemicals operating expenses were reduced from the prior
year.

Earnings from other operations, including coal, minerals and power, totaled
$108 million, compared to $102 million in the third quarter of 1998. Earnings
improved on higher copper prices and volumes and continued reductions in
operating expenses.

Corporate and financing expenses of $62 million compared with $69 million in
the third quarter of last year.

During the third quarter of 1999, Exxon purchased 1.0 million shares of its
common stock for the treasury at a cost of $84 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 of 1998.

FIRST NINE MONTHS 1999 COMPARED WITH FIRST NINE MONTHS 1998

Net income was $3,725 million for the first nine months of 1999, a decrease of
23 percent from the $4,840 million earned in 1998. Net income for the first
nine months 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, net income for
the first nine months of 1999 declined 22 percent to $3,845 million or $1.57
per share, compared to $4,910 million or $1.99 per share last year.

Exploration and production earnings have increased due to the improvement in
crude prices. Crude oil realizations were up almost $3 per barrel versus the
first nine months of 1998. However, European gas prices were about 20 percent
lower than the previous year. Liquids production of 1,544 kbd compared to 1,595
kbd in the same period of 1998, primarily due to natural field declines, steps
to curtail marginal volumes in the low price environment of the first half of
the year and lower liftings in Canada. Partly offsetting this was increased
production from new developments in the North Sea, the Gulf of Mexico and
Azerbaijan. Worldwide natural gas production of 6,008 mcfd was essentially
unchanged from the prior year. Exploration and producing expenses were reduced
from prior year levels.

Earnings from U.S. exploration and production operations for the first nine
months were $856 million, an increase of $231 million from 1998. Outside the
U.S., exploration and production earnings were $1,488 million, up $34 million
from last year.

Petroleum product sales of 5,443 kbd increased 30 kbd over last year,
principally due to volume growth in North America. Earnings from U.S. refining
and marketing operations were $214 million, down $254 million from 1998,
reflecting the inability to pass through higher crude costs to the marketplace.
Outside the U.S., refining and marketing earnings for the first nine months,
excluding non-recurring items, decreased $1,020 million to $327 million, driven
by much lower margins, higher planned maintenance activities and unfavorable
foreign exchange effects. Reduced operating expenses provided some offset to
these factors.

                                  -14-

                                  EXXON CORPORATION

Chemicals earnings totaled $882 million for the first nine months of 1999
compared with $970 million last year. Industry margins declined versus last
year due to lower product prices and higher feedstock costs. Prime product
sales volumes of 13,428 kt were a record for the first nine months and
increased 4 percent over last year. Chemicals earnings also benefited from
lower operating expenses.

Earnings from other operations totaled $290 million, a decrease of $4 million
from the first nine months of 1998, reflecting depressed copper and coal
prices, offset by reduced operating expenses and higher production volumes.
1999 year-to-date production volumes for copper and coal were at record levels.
Corporate and financing expenses decreased $36 million to $212 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 $2,650 million in the first
nine months of 1999 versus $3,803 million in the same period last year.
Operating activities provided net cash of $7,857 million, a decrease of $1,495
million from the prior year influenced by lower net income. Investing
activities used net cash of $5,207 million or $342 million less than a year
ago, reflecting higher proceeds from asset sales.

Net cash used in financing activities was $2,966 million in the first nine
months of 1999 versus $5,760 million in the same period last year, 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 nine months of 1999, Exxon purchased 7.5
million shares of its common stock for the treasury at a cost of $579 million,
representing a continuation of purchases to offset shares issued in conjunction
with the Company's benefit plans and programs. 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 of 1998.

Capital and exploration expenditures in this year's first nine months were
$6,602 million versus $7,079 million a year ago.

Total debt of $9.2 billion at September 30, 1999 increased $0.5 billion from
year-end 1998. The corporation's debt to total capital ratio was 16.8 percent
at the end of the third quarter of 1999, compared to 16.2 percent at year-end
1998.

Over the twelve months ended September 30, 1999, return on average
shareholders' equity was 12.0 percent. Return on average capital employed,
which includes debt, was 10.3 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.

                                  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 in identified
mission critical systems, are complete. The modification and testing phases
related to identified mission critical systems are essentially complete.
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 80 percent 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 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.

                                 EXXON CORPORATION

Through September 30, 1999, about $225 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 $230 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.
