</TABLE>
- ----------
(1)   The maximum number of shares of Exxon common stock issuable in connection
      with the merger in exchange for shares of Mobil common stock, based on (i)
      the maximum number of shares of Mobil common stock exchangeable in the
      merger (833,000,000 shares) and (ii) the exchange ratio applicable in the
      merger (1.32015 shares of Exxon common stock for each share of Mobil
      common stock).

(2)   Estimated solely for the purpose of calculating the registration fee
      pursuant to Rule 457(f)(1) and Rule 457(c) of the Securities Act, based on
      the market value of the Mobil shares to be received by Exxon in the
      merger, as established by the average of the high and low sales prices of
      Mobil common stock on April 1, 1999 on the consolidated tape, which was
      $87.34375.

(3)   This fee has been calculated pursuant to Section 6(b) of the Securities
      Act, as .0278 of one percent of $72,757,343,750. In accordance with Rule
      457 under the Securities Act, the fee of $14,003,550 paid by the
      Registrant and Mobil pursuant to Rule 14a-6(i)(1) under the Securities
      Exchange Act upon the filing of their preliminary proxy material relating
      to the merger has been credited against the registration fee payable in
      connection with this filing. The balance of the fee payable with this
      filing is therefore $6,222,991.56.

                             -----------------------


   The Registrant hereby amends this Registration Statement on such date or
dates as may be necessary to delay its effective date until the Registrant shall
file a further amendment which specifically states that this Registration
Statement shall thereafter become effective in accordance with Section 8(a) of
the Securities Act of 1933 or until this Registration Statement shall become
effective on such date as the Commission, acting pursuant to said Section 8(a),
may determine.

      [PRELIMINARY DRAFT DATED APRIL 5, 1999, SUBJECT TO COMPLETION]

              MERGER PROPOSED -- YOUR VOTE IS VERY IMPORTANT

The Boards of Directors of Exxon Corporation and Mobil Corporation have
approved a merger agreement which provides for the combination of the two
companies.  We believe the combined company will be able to create
substantially more shareholder value than could be achieved by the companies
individually.

Our combined company would be named Exxon Mobil Corporation, with its
headquarters in Irving, Texas.  Sometimes in this booklet we will refer to the
combined company as "Exxon Mobil".

If the merger is completed, holders of Mobil common stock will receive, for
each Mobil share, 1.32015 shares of Exxon Mobil common stock, and each share
of Mobil ESOP preferred stock will be converted into an equivalent share of a
newly created class of Exxon Mobil preferred stock.  Exxon shareholders will
continue to own their existing shares after the merger.  Sometimes in this
booklet we refer to Exxon stock after the closing of the merger as "Exxon
Mobil stock".

Exxon Mobil will issue approximately 1.03 billion shares of Exxon Mobil common
stock to Mobil shareholders in the merger, based on outstanding shares on
March 1, 1999.  These shares will represent approximately 30% of the
outstanding Exxon Mobil common stock after the merger.  Exxon shares held by
Exxon shareholders before the merger will represent approximately 70% of the
outstanding Exxon Mobil shares after the merger.

We are asking shareholders of Exxon to approve the merger and related matters
and to vote on the election of Exxon directors and other Exxon annual meeting
matters described in this booklet.

We are asking shareholders of Mobil to approve the merger agreement and the
merger and to vote on the election of Mobil directors and other Mobil annual
meeting matters described in this booklet.  If the merger is completed, these
Mobil annual meeting matters will, as a result, be superseded.

We cannot complete the merger unless shareholders of both companies approve
it.  Approval of the other annual meeting matters is not a condition of the
merger.

The dates, times and places of the meetings are:

   For Exxon shareholders:

       Thursday, May 27, 1999
       10:00 a.m., Central Time
       Trinity Conference Center
       Wyndham Anatole Hotel

                                   CHAPTER ONE
                                   THE MERGER

                     QUESTIONS AND ANSWERS ABOUT THE MERGER

Q: When and where are the shareholder meetings?

A: Each company's meeting will take place on May 27, 1999 in Dallas, Texas.  The
address of each meeting is on page II-1.

Q: What do I need to do now?

A: Just mail your signed proxy card in the enclosed return envelope or vote by
telephone or the internet, as soon as possible, so that your shares may be
represented at your meeting. In order to assure that your vote is obtained,
please give your proxy as instructed on your proxy card even if you currently
plan to attend a meeting in person. The Board of Directors of each of Exxon and
Mobil recommends that its shareholders vote in favor of the merger.

Q: What do I do if I want to change my vote?

A: Just send in a later-dated, signed proxy card to your company's Secretary or
vote again by telephone or the internet before your meeting. Or, you can attend
your meeting in person and vote. You may also revoke your proxy by sending a
notice of revocation to your company's Secretary at the address under "The
Companies" on page I-2.

Q: If my shares are held in "street name" by my broker, will my broker vote
my shares for me?

A: If you do not provide your broker with instructions on how to vote your
"street name" shares, your broker will not be permitted to vote them on the
merger. You should therefore be sure to provide your broker with instructions on
how to vote your shares. Please check the voting form used by your broker to see
if it offers telephone or internet voting.

If you are an Exxon shareholder and do not give voting instructions to your
broker, you will not be counted as voting for purposes of the merger vote unless
you appear in person at the Exxon meeting.

If you are a Mobil shareholder and do not give voting instructions to your
broker, you will, in effect, be voting against the merger unless you appear in
person at the Mobil meeting and vote in favor of the merger.

Q: Should I send in my stock certificates now?

A: No. If the merger is completed, we will send Mobil shareholders written
instructions for exchanging their share certificates. Exxon shareholders will
keep their existing certificates.

Q: What happens to my future dividends?

A: We expect no changes in Exxon's or Mobil's dividend policies before the
merger. We expect that Exxon Mobil will continue to pay quarterly dividends on
Exxon Mobil common stock after the merger. The payment of dividends by Exxon
Mobil in the future, however, will depend on business conditions, Exxon Mobil's
financial condition and earnings, and other factors. To compare dividends paid
by each of Exxon and Mobil, see page I-30.

Q: When do you expect the merger to be completed?

A: We are working towards completing the merger as quickly as possible. In
addition to shareholder approvals, we must also obtain regulatory approvals. We
hope to complete the merger by mid-year, 1999.

Q: Who do I call if I have questions about the meetings or the merger?

A: Exxon shareholders may call 1-800-628-8536.
   Mobil shareholders may call 1-800-300-3610.

Chapter One - The Merger


                                     SUMMARY

This summary highlights selected information from this joint proxy
statement/prospectus and may not contain all of the information that is
important to you. To understand the merger fully and for a more complete
description of the legal terms of the merger, you should read this document and
the documents we have referred you to carefully. See "Where You Can Find More
Information" on page VI-1.

The Companies

Exxon Corporation
5959 Las Colinas Boulevard
Irving, Texas 75039-2298
(972) 444-1000

Exxon's principal business is energy, involving exploration for, and production
of, crude oil and natural gas, manufacturing of petroleum products and
transportation and sale of crude oil, natural gas and petroleum products. Exxon
is also a major manufacturer and marketer of petrochemicals, including olefins,
aromatics, polyethylene and polypropylene plastics, and a wide array of
specialty products. Exxon also engages in exploration for, and mining and sale
of, coal, copper and other minerals, and has interests in electric power
generation. Exxon affiliates support our businesses with extensive research
programs.

Mobil Corporation
3225 Gallows Road
Fairfax, Virginia 22307-0001
(703) 846-3000

Mobil's principal business involves crude oil, natural gas and petroleum
products. Mobil is also a manufacturer and marketer of petrochemicals, packaging
films and specialty chemical products. Mobil operates a worldwide oil and gas
exploration and producing business, a global marketing and refining complex, a
network of pipelines and tankers linking these worldwide oil and gas businesses,
a worldwide chemical business and a sophisticated research and engineering
operation.

Reasons for the Merger

We believe the combined Exxon Mobil can be run more efficiently and can use its
capital more profitably than either company on its own. As a result, we believe
the merger will create substantial long-term value for the shareholders of both
companies. Of course, these benefits depend on our ability to obtain the
necessary approvals for the merger, to integrate the businesses of Exxon and
Mobil successfully after the merger, and on other uncertainties described on
page I-12.

To review the reasons for the merger in greater detail, see pages I-19 through
I-26.

Merger Recommendations to Shareholders

To Exxon Shareholders:

The Exxon Board believes that the merger is fair to you and in your best
interest and recommends that you vote FOR the merger, including the related
issuance of common stock and the related amendments to Exxon's charter described
on page III-10.

To Mobil Shareholders:

The Mobil Board believes that the merger is fair to you and in your best
interest and recommends that you vote FOR the approval of the merger agreement
and the merger.

The Merger

The merger agreement is attached as Annex A to this joint proxy
statement/prospectus. We encourage you to read the merger agreement as it is the
legal document that governs the merger.

What Mobil Shareholders Will Receive (see page I-54)

As a result of the merger, Mobil shareholders will receive, for each share of
Mobil common stock, 1.32015 shares of Exxon Mobil common stock.

                                      I-2
<PAGE>


                                                      Chapter One - The Merger


Exxon Mobil will not issue any fractional shares. Mobil shareholders will
receive a check in the amount of the proceeds from the sale of their fractional
shares in the market.

Example:

  o   If you currently own 1,000 shares of
      Mobil common stock, then after the
      merger you will receive 1,320 shares
      of Exxon Mobil common stock and a
      check for the sale proceeds for .15 of
      one share of Exxon Mobil common
      stock, rounded to the nearest one cent.
      The value of the stock that you will
      receive will fluctuate as the price of
      Exxon Mobil common stock changes
      after the merger.

  o   On April 1, 1999 the last per share
      price of Exxon common stock on the
      Consolidated Tape was $70 1/8.
      Applying the 1.32015 exchange ratio
      to the Exxon last reported price on
      that date, each holder of Mobil
      common stock would be entitled to
      receive Exxon Mobil common stock
      with a market value of approximately
      $92.58 for each share of Mobil
      common stock.  However, the market
      prices for Mobil and Exxon common
      stock are likely to change between
      now and the merger.  You are urged
      to obtain current price quotes for
      Mobil and Exxon common stock.

Comparative Per Share Market Price Information

Exxon and Mobil common stock are both listed on the New York Stock
Exchange.  On November 25, 1998, the last full trading day before Exxon and
Mobil issued a joint release confirming that they were in discussions
concerning a possible combination, Exxon common stock closed at $72 11/16
and Mobil common stock closed at $78 3/8.  On November 30, 1998, the last
full trading day prior to the public announcement of the proposed merger,
Exxon closed at $75 and Mobil closed at $86.  On April 1, 1999, Exxon
closed at $70 1/8 and Mobil closed at $87 3/8.

Listing of Exxon Mobil Common Stock

The shares of Exxon Mobil common stock will be listed on the New York Stock
Exchange under the ticker symbol "XOM".

Ownership of Exxon Mobil After the Merger

Exxon Mobil will issue approximately 1.03 billion shares of Exxon Mobil common
stock to Mobil shareholders in the merger. The shares of Exxon Mobil common
stock to be issued to Mobil shareholders in the merger will represent
approximately 30% of the outstanding Exxon Mobil common stock after the merger.
This information is based on the number of Exxon and Mobil shares outstanding on
March 1, 1999 and does not take into account stock options or other equity-based
awards.

Shareholder Vote Required to Approve the Merger

For Exxon shareholders: Approval of the merger and related matters described on
page I-14 requires a majority of the votes cast by holders of Exxon common stock
and Exxon Class A preferred stock, voting as a single class.

For Mobil shareholders: Approval of the merger requires a majority of the total
votes represented by the outstanding shares of Mobil common stock and Mobil ESOP
preferred stock, voting as a single class.

Appraisal Rights (see page I-29)

The holders of Exxon and Mobil common stock do not have any right to an
appraisal of the value of their shares in connection with the merger. We provide
on page I-29 in the section captioned "The Merger Transaction--Appraisal Rights"
information regarding the appraisal rights available in connection with the
merger to the trustee of the Mobil ESOP, the sole record holder of Mobil ESOP
preferred stock.

Board of Directors of Exxon Mobil and Related Matters After the Merger

Following the merger, the board of directors of Exxon Mobil will have 19
members, including the 13 current Exxon directors plus six directors designated
by Mobil. These designees are named below (see page I-55). Mr. Lucio A. Noto,
Chairman of Mobil, will become the Vice-Chairman of Exxon Mobil. In addition,
one Mobil designee will be appointed to each of Exxon Mobil's Audit Committee
and Compensation Committee. (see page I-55.)

                                      I-3
<PAGE>


Chapter One - The Merger


Interest of Officers and Directors in the Merger

When you consider the Mobil Board's recommendation that Mobil shareholders vote
in favor of the merger, you should be aware that a number of Mobil officers and
directors may have interests in the merger that may be different from, or in
addition to, yours (see page I-49).

Accounting Treatment

We expect the merger to qualify as a pooling of interests, which means that we
will treat our companies as if they had always been combined for accounting and
financial reporting purposes. As described on page I-26, we have each received
letters from our independent accounting firms concurring with our conclusions
that the merger should be accounted for as a pooling of interests.

Material Federal Income Tax Consequences of the Merger (see page I-27)

The merger has been structured as a "tax-free reorganization" for federal income
tax purposes. Accordingly, holders of Mobil common stock or Mobil ESOP preferred
stock generally will not recognize any gain or loss for federal income tax
purposes on the exchange of their Mobil stock for Exxon Mobil stock in the
merger, except for any gain or loss recognized in connection with the receipt of
cash instead of a fractional share of Exxon Mobil common stock. The companies
themselves, as well as holders of Exxon stock, will not recognize gain or loss
as a result of the merger. It is a condition to the obligations of Mobil and
Exxon to complete the merger that each receive a legal opinion from its outside
counsel that the merger will be a tax-free reorganization for federal income tax
purposes.

The federal income tax consequences described above may not apply to some
holders of Mobil stock, including some types of holders specifically referred to
on page I-27. Your tax consequences will depend upon your personal situation.
You should consult your tax advisor for a full understanding of the tax
consequences of the merger to you.

Conditions to the Completion of the Merger (see page I-58)

The completion of the merger depends upon meeting a number of conditions,
including the following:

   o  approval of the shareholders of Exxon and Mobil;

   o  expiration or termination of the relevant waiting period under the
      Hart-Scott-Rodino Act;

   o  approval by the European Commission of the merger;

   o  absence of any law or court order prohibiting the merger;

   o  receipt of letters from the independent public accountants of Exxon and
      Mobil reconfirming their concurrence that "pooling of interests"
      accounting treatment for the merger is appropriate;

   o  receipt of opinions of Exxon's and Mobil's counsel that the merger will
      qualify as a tax-free reorganization;

   o  absence of a material adverse effect on Exxon or Mobil during the period
      from December 1, 1998 until the closing of the merger; and

   o  material accuracy as of closing of the representations and warranties made
      by the other party.

In addition, Exxon's obligation to complete the merger is subject to

 (1)  there being no proceeding seeking to limit Exxon's ownership of Mobil or
      to compel divestiture of assets, in either case to an extent that could
      reasonably be expected to result in a substantial detriment to Exxon and
      Mobil taken as a whole; and

 (2)  all regulatory approvals for the merger being obtained on terms that are
      not reasonably likely to result in such a substantial detriment.

                                      I-4

                                                      Chapter One - The Merger


Regulatory Approvals

Pursuant to the Hart-Scott-Rodino Act, the merger cannot be completed until
after we have given certain information and materials to the Federal Trade
Commission and a required waiting period has expired or been terminated. The
companies submitted pre-merger notification and report forms during the week of
December 14, 1998. On January 15, 1999, the FTC issued a request for additional
information and other materials to Exxon and Mobil. The merger may not be
completed until 20 days after both parties have substantially complied with this
request or unless the waiting period is terminated earlier. The FTC has the
authority to challenge the merger on antitrust grounds by seeking a federal
court order enjoining the transaction pending an administrative hearing.

The merger is also subject to review under the competition laws of the European
Union. We informally notified the European Commission of the merger on December
1, 1998, and expect to make the required formal pre-merger filing by the end of
April 1999.

The merger may also be subject to regulatory review in jurisdictions other than
the U.S. and the EU.

Exxon and Mobil are working to obtain the required regulatory approvals and
consents. However, we can give no assurance as to when or whether any of these
approvals and consents will be obtained or the terms and conditions that may be
imposed.

As described beginning on page I-58, Exxon and Mobil are not required to close
unless the regulatory conditions to completion of the merger are satisfied.

Termination of the Merger Agreement (see page I-59)

Either Exxon or Mobil can terminate the merger agreement if any of the following
occurs:

 (1)  we do not complete the merger by December 1, 1999 -- however, that date
      becomes June 30, 2000 if the reason for not closing by December 1, 1999 is
      that the regulatory conditions specified in the merger agreement have not
      been satisfied by that date;

 (2)  Exxon or Mobil shareholders do not give the required approvals;

 (3)  a law or court order permanently prohibits the merger; or

 (4)  the Mobil Board changes, in a manner adverse to Exxon, its recommendation
      of the merger. An adverse change would include the Mobil Board withdrawing
      or qualifying its recommendation or changing the recommendation to support
      another transaction. However, Mobil may not terminate for the reasons laid
      out in this paragraph (4) unless three conditions are met:

        o  Mobil has received an offer that is superior to the merger with Exxon
           and intends to enter into an agreement with respect to the superior
           offer,

        o  Exxon, within a specified time period, does not make an offer that is
           as favorable to Mobil's shareholders as the superior offer, and

        o  Mobil has, prior to termination, paid to Exxon the termination fee
           described below.

In addition, Mobil can terminate the merger agreement if the Exxon Board changes
its recommendation of the merger in a manner adverse to Mobil.

Neither Exxon nor Mobil can terminate the merger agreement for the reasons
described in paragraph (1) above if it is in material breach of its obligations
under the merger agreement.

Finally, Exxon and Mobil can mutually agree to terminate the merger agreement.

Termination Fees (see page I-60)

Mobil must pay Exxon a termination fee of $1.5 billion in cash if:

 (1)  the merger agreement is terminated as described in paragraph (4) above,
      unless Exxon is in material breach of the merger agreement, or

                                      I-5


<PAGE>


Chapter One - The Merger


 (2)  the merger agreement is terminated in circumstances where

        o   Mobil's shareholders do not vote
            in favor of the merger,

        o   a third party has made a proposal
            for an alternative transaction, and

       o    within twelve months of the
            termination of the merger
            agreement Mobil enters into an
            agreement for an alternative
            transaction with that third party,
            or with another third party at a
            value per Mobil share higher
            than $95.96.

Exxon must pay Mobil a termination fee of $1.5 billion in cash if the merger
agreement is terminated by Mobil because the Exxon Board changes, in a manner
adverse to Mobil, its recommendation in favor of the merger, unless Mobil is in
material breach of the merger agreement.

Stock Option Agreement

In connection with the merger agreement, Exxon and Mobil entered into a stock
option agreement under which Mobil granted to Exxon an option to purchase
approximately 14.9% of Mobil's outstanding common stock, at a price of $95.96
per share which is adjustable in certain events. The option is exercisable under
the same circumstances in which Mobil is required to pay to Exxon the $1.5
billion termination fee referred to above. The stock option agreement is
attached as Annex B. We encourage you to read this agreement.

Opinions of Financial Advisors (see pages I-39 and I-44)

In deciding to approve the merger, each Board considered the opinion of its
financial advisor. Exxon received an opinion from J.P. Morgan Securities Inc. as
to the fairness from a financial point of view of the consideration to be paid
by Exxon in the merger as of December 1, 1998, and Mobil received an opinion
from Goldman, Sachs & Co. as to the fairness from a financial point of view of
the exchange ratio as of December 1, 1998. These opinions were reaffirmed as of
April 2, 1999 and are attached as Annex C and Annex D. We encourage you to read
these opinions.

Other Exxon Annual Meeting Matters

At the Exxon meeting, Exxon is also asking its shareholders to:

   o   elect directors to the Exxon Board;

   o   ratify the appointment of Exxon's independent accountants;

   o   vote on four Exxon shareholder proposals; and

   o   conduct other business if properly presented.

Approval by Exxon shareholders of these other annual meeting proposals is not a
condition to completion of the merger. Approval of the merger is not a condition
to approval of these other annual meeting proposals.

The Exxon Board recommends that you vote FOR the election of directors and the
ratification of the appointment of Exxon's independent accountants, and that you
vote AGAINST the Exxon shareholder proposals.

Other Mobil Annual Meeting Matters

At the Mobil meeting, Mobil is also asking its shareholders to:

   o   elect directors to the Mobil Board;

   o   ratify the appointment of Mobil's independent auditors;

   o   vote on two Mobil shareholder proposals; and

   o   conduct other business if properly presented.

Approval by Mobil shareholders of these other annual meeting proposals is not a
condition to completion of the merger. Approval of the merger is not a condition
to approval of these other annual meeting proposals. If the merger is completed,
these other annual meeting proposals will, as a result, be superseded.

The Mobil Board recommends that you vote FOR the election of directors and the
ratification of the appointment of Mobil's independent auditors, and that you
vote AGAINST the Mobil shareholder proposals.

                SELECTED HISTORICAL AND PRO FORMA FINANCIAL DATA

   How We Prepared the Financial Statements

     We are providing the following information to aid you in your analysis of
the financial aspects of the merger. We derived this information from the
audited financial statements of Exxon for the years 1994 through 1998 and from
the audited financial statements of Mobil for the years 1994 through 1998. The
information is only a summary and you should read it together with our
historical financial statements and related notes contained in the annual
reports and other information that we have filed with the SEC and incorporated
by reference. See "Where You Can Find More Information" on page VI-1.

   Pooling of Interests Accounting Treatment

     We expect that the merger will be accounted for as a "pooling of
interests." This means that, for accounting and financial reporting purposes, we
will treat our companies as if they had always been combined. For a more
detailed description of pooling of interests accounting, see "The Merger
Transaction--Accounting Treatment" on page I-26.

     We have presented unaudited pro forma condensed combined financial
information that reflects the pooling of interests method of accounting to give
you a better picture of what our businesses might have looked like had they been
combined since January 1, 1996. We prepared the pro forma condensed combined
statements of income and pro forma condensed combined balance sheet by adding or
combining the historical amounts of each company. The accounting policies of
Exxon and Mobil are substantially comparable. Consequently, we did not make
adjustments to the unaudited pro forma condensed combined financial statements
to conform the accounting policies of the combining companies. The companies may
have performed differently had they always been combined. You should not rely on
the unaudited pro forma condensed combined financial information as being
indicative of the historical results that we would have had or the future
results that we will experience after the merger. See "Unaudited Pro Forma
Condensed Combined Financial Statements" on page I-32.

   Merger-Related Expenses

     We estimate that merger-related fees and expenses, consisting primarily of
SEC filing fees, fees and expenses of investment bankers, attorneys and
accountants, and financial printing and other related charges, will be
approximately $90 million. See note 5 on pages I-37 and I-38.

   Integration-Related Expenses

     We estimate that costs of approximately $2.0 billion 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. These costs will be charged to operations in the relevant
period and therefore are not reflected in the unaudited pro forma condensed
combined financial statements. See note 5 on pages I-37 and I-38.

   Periods Covered

     The unaudited pro forma condensed combined statements of income combine
Exxon's results for the years 1998, 1997 and 1996 with Mobil's results for the
years 1998, 1997 and 1996, giving effect to the merger as if it had occurred on
January 1, 1996. The unaudited pro forma condensed combined balance sheet
combines the balance sheets of Exxon and Mobil as of December 31, 1998, giving
effect to the merger as if it had occurred on December 31, 1998.

Comparative Per Share Data

     Set forth below are the net income, cash dividends and book value per
common share data separately for Exxon and Mobil on a historic basis, for Exxon
Mobil on a pro forma combined basis and on a pro forma combined basis per Mobil
equivalent share. The exchange ratio for the business combination is 1.32015
shares of Exxon Mobil common stock for each share of Mobil common stock.

     The Exxon Mobil pro forma data was derived by combining the historic
consolidated financial information of Exxon and Mobil using the pooling of
interests method of accounting for business combinations as described under
"Unaudited Pro Forma Condensed Combined Financial Statements" beginning on page
I-32.

     The Mobil equivalent share pro forma information shows the effect of the
merger from the perspective of an owner of Mobil common stock. The information
was computed by multiplying the Exxon Mobil pro forma information by the
exchange ratio of 1.32015.

     You should read the information below together with our historical
financial statements and related notes contained in the annual reports and other
information that we have filed with the SEC and incorporated by reference. See
"Where You Can Find More Information" on page VI-1. The unaudited pro forma
combined data below is for illustrative purposes only. The companies may have

                                 YEAR 2000 ISSUE

     Exxon and Mobil are each engaged in major company-wide efforts to address
the year 2000 issue. This issue relates to the inability of some computer
programs and computer chips embedded in operating equipment to properly
recognize dates in and after the year 2000. This could result in system failures
or miscalculations that could cause disruptions to various business activities
and operations. The efforts to address this issue generally include:

               (1) the identification and assessment from a year 2000 standpoint
          of all business-critical software systems and operating equipment and
          the remediation of those that are not year 2000 compliant;

               (2) the assessment of the year 2000 readiness of
          business-critical third parties such as suppliers, customers, joint
          venture companies and governments; and

               (3) the development of contingency plans for mitigating the
          impact of failures for year 2000 reasons of business-critical systems,
          operating equipment or relationships with third parties.

     Exxon and Mobil expect to complete their efforts to address the year 2000
issue in advance of December 31, 1999, and each is planning to take steps to
deal with possible year 2000 issues that may arise around that date. Each
company's effort is designed to address the company's unique systems, embedded
computer chips and third-party relationships, and each effort is well advanced.
Accordingly, irrespective of when the merger is completed, each company's effort
will continue as planned to completion. There will be no major integration of
the companies' computer systems that would delay either company's year 2000
compliance efforts.

Chapter One - The Merger


                             THE MERGER TRANSACTION

General

     Exxon's Board is using this joint proxy statement/prospectus to solicit
proxies from the holders of Exxon common stock and Exxon Class A preferred stock
for use at the Exxon meeting. Mobil's Board is also using this document to
solicit proxies from the holders of Mobil common stock and Mobil ESOP preferred
stock for use at the Mobil meeting.

     Exxon Proposals

     At the Exxon meeting, holders of Exxon common stock and Exxon Class A
preferred stock will be asked to vote upon:

               (1) approval of the proposed merger pursuant to an Agreement and
          Plan of Merger dated as of December 1, 1998 among Exxon, Mobil and a
          wholly owned Exxon subsidiary, including the related issuance of Exxon
          Mobil common stock,

               (2) approval of the amendment of Exxon's certificate of
          incorporation to increase the number of authorized shares of Exxon
          common stock to 4.5 billion, to change Exxon's name to "Exxon Mobil
          Corporation" and to eliminate Exxon's Class B preferred stock, none of
          which is outstanding, and

               (3) certain other Exxon annual meeting proposals described under
          "Other Exxon Annual Meeting Proposals" in Chapter Four of this
          booklet.

     The merger will not be completed and the Exxon charter amendments will not
be effected unless each is approved by Exxon shareholders. We sometimes refer to
(1) and (2) collectively as the "Exxon Merger Proposals".

     Mobil Proposals

     At the Mobil meeting, holders of Mobil common stock and Mobil ESOP
preferred stock will be asked to vote upon:

               (1)  approval and adoption of the merger agreement and the
          merger, and

               (2) certain other Mobil annual meeting proposals described under
          "Other Mobil Annual Meeting Proposals" in Chapter Five of this
          booklet.

Background of the Merger

     The management of each of Exxon and Mobil continually review their
company's respective positions in light of the changing competitive environment
of the oil and gas industry with the objective of determining what alternatives
are available to further enhance shareholder value. While both companies believe
they have positive future prospects on a stand-alone basis, in recent years, the
managements of both Exxon and Mobil have had conversations with a number of
other companies regarding a range of options to improve their competitive
positions, including acquisitions or dispositions of assets, possible
partnerships, alliances or other significant transactions.

     On June 16, 1998, Mr. Lee R. Raymond, Exxon's Chairman and Chief Executive
Officer, met with Mr. Lucio A. Noto, Mobil's Chairman and Chief Executive
Officer, at Mobil's headquarters in Fairfax, Virginia. At the meeting, among
other things, Mr. Raymond and Mr. Noto had preliminary discussions about the
possibility of a combination of the two companies and touched on what each
company could contribute to the combination in both

                                      I-14

                                                      Chapter One - The Merger


the near- and longer-term, including areas where the companies' businesses
are complementary or redundant, and on the possible allocation of
management responsibilities and Board composition.  They agreed that Mr.
Raymond would serve as sole CEO of any combined entity that might result
from the discussions.  They agreed to further consider separately the
possibility of such a transaction.  On June 23, 1998, Mr. Noto telephoned
Mr. Raymond to continue the discussions from their meeting the previous
week.  At the regular meeting of the Mobil Board on June 26, 1998, Mr.
Noto informed the Mobil Board of his meeting with Mr. Raymond.

     On July 1, 1998, Mr. Raymond and Mr. Charles W. Matthews, Exxon's general
counsel, met with Mr. Noto and Mr. Samuel H. Gillespie III, senior vice
president and general counsel of Mobil, at Exxon's headquarters in Irving, Texas
to continue the preliminary discussions concerning the possibility of a
transaction. The discussions focused on the need to identify, in the context of
the near- and longer-term benefits, a mutually acceptable range for the possible
relative ownerships by Exxon and Mobil shareholders of the combined company
after the merger, before proceeding to discuss other transaction terms or to
involve a significant number of other employees or outside advisors. Later that
day, Mr. Noto notified the Mobil Board of the discussions between Mobil and
Exxon. During the course of the month of July, Mr. Raymond and Mr. Noto had
several further telephone conversations in which they continued to discuss their
views on the benefits to shareholders of a possible combination transaction and
an acceptable relative ownership range.

     At the regular meeting of the Mobil Board on July 24, 1998, Mr. Noto
briefed the Mobil Board on the preliminary discussions with Exxon regarding a
possible combination transaction. Mr. Noto discussed with the Mobil Board recent
developments in the oil industry and the potential benefits of a combination
transaction between Exxon and Mobil. The Mobil Board indicated its support of
initiatives to enhance shareholder value and authorized Mr. Noto to continue to
pursue the possibility of a combination transaction between Mobil and Exxon.

     At the regular meeting of the Exxon Board on July 29, 1998, Mr. Raymond
briefed the Exxon Board on the preliminary discussions with Mr. Noto regarding
the possibility of a combination transaction between Exxon and Mobil. Mr.
Raymond reviewed with the Board recent developments in the oil industry and his
preliminary views on the potential near- and longer-term benefits and operating
and capital synergies of such a combination transaction and some of the terms on
which such a transaction might occur. The Exxon Board indicated its support for
the objectives and opportunities to further enhance shareholder value described
by Mr. Raymond and encouraged Mr. Raymond to continue to explore the possibility
of a transaction which would achieve these objectives.

     In early August 1998, Mr. Raymond and Mr. Noto continued telephone
discussions on a number of important aspects of a possible merger, including
possible relative ownership ranges. Not having identified a mutually acceptable
range, in a conversation on August 5, Messrs. Raymond and Noto mutually agreed
to discontinue discussions. On August 6, Mr. Noto notified the Mobil Board of
the discontinuation of discussions between Exxon and Mobil.

     On August 11, 1998, The British Petroleum Company p.l.c. and Amoco
Corporation announced the terms of their merger agreement. In any negotiation,
price information from recent, comparable deals helps the parties identify a
benchmark price range for their transaction. Before BP/Amoco was announced,
Exxon and Mobil could only compare their proposed transaction with recent deals
involving companies that were much smaller or in different industries. Pricing
in these other deals varied widely and did not help Exxon and Mobil identify an
appropriate range for their discussions. BP/Amoco, however, involved companies
operating on a similar scale to Exxon and Mobil within the same industry. The
transaction therefore provided Exxon and Mobil with a better reference point
from which to discuss price and other key terms.

     Shortly thereafter, Mr. Raymond and Mr. Noto resumed their discussions
taking into account this new pricing benchmark. They concluded that for
discussions to progress, the parties would need to develop a better
understanding of the potential near-term synergies and cost savings as well as
longer-term capital efficiencies and strategic benefits that could be
realized from a merger.  They agreed to meet again in New Orleans on
September 3, 1998.

Chapter One - The Merger


     In mid-August 1998, the management of Mobil asked Goldman Sachs to
undertake an analysis of strategic alternatives available to Mobil. In late
August and September 1998, Mobil management met with Goldman Sachs to discuss
Goldman Sachs' analyses, which included a preliminary analysis of a possible
merger with Exxon as well as other possible alternatives, including preliminary,
hypothetical analyses of possible combinations and joint venture transactions
with large publicly-traded oil companies other than Exxon. At that time, Mobil
had not advised Goldman Sachs that Mobil was engaged in discussions with Exxon
regarding a potential transaction.

     At the September 3 meeting, Messrs. Raymond and Matthews, together with Mr.
Rene Dahan and Mr. Harry J. Longwell, senior vice presidents and directors of
Exxon, met with Messrs. Noto and Gillespie and other senior executives of Mobil,
including Mr. Eugene A. Renna, President, Chief Operating Officer and a director
of Mobil. Discussions focused on Mobil's identification of potential near-term
savings and longer-term benefits achievable from a potential merger. Mobil
presented its preliminary analysis of the synergies which it believed would be
achievable by the third anniversary of the closing. The scope of synergies
discussed at this meeting included savings achievable through elimination of
duplicative overheads at the corporate and operating levels; focusing the
combined company's exploration and capital programs on high quality investments;
and efficiencies resulting from economies of scale and sharing of best practices
in, for example, refining operations, raw material purchasing, product
transportation and handling of inventory. In addition, Mobil and Exxon agreed
that achieving near-term cost reductions was not a sufficient reason to merge,
and that it was essential that they also expect to achieve long-term benefits in
order to justify merging. As examples of long-term benefits Exxon and Mobil
discussed the ability of the combined company to use its capital more profitably
than either company on its own and to compete more effectively with the scale
and cost structure of the largest international firms. Exxon and Mobil
acknowledged that these long-term benefits would be difficult to quantify.

     On September 14, 1998, Goldman Sachs presented to the Mobil Board its
analyses regarding the various possible transactions that might be considered by
Mobil, including a possible merger with Exxon. Following its presentation,
Goldman Sachs was requested to consider additional hypothetically possible
transactions with large publicly-traded oil companies. At that time, Mobil had
not advised Goldman Sachs that Mobil was engaged in discussions with Exxon
regarding a potential transaction. After Goldman Sachs was excused from the
meeting, Mr. Noto briefed the Mobil Board on the recent developments in
discussions between Mobil and Exxon.

     On September 16, 1998, Mr. Noto called Mr. Raymond to confirm that Mobil
had provided Exxon with sufficient information for Exxon to perform its analysis
regarding potential synergies. They discussed issues raised at the September 3
meeting, including the ability of the combined company to manage assets for a
greater return than each company could achieve individually, and agreed to a
further meeting at Exxon's headquarters on September 24. At this meeting,
Messrs. Raymond and Matthews continued discussions with Messrs. Noto and
Gillespie principally on mutually acceptable relative ownership ranges, and
near- and longer-term benefits of the merger. After this meeting, Mobil advised
Goldman Sachs that Mobil was engaged in discussions with Exxon regarding a
potential transaction.

     At a regular meeting of the Mobil Board on September 25, 1998 at which
Mobil's financial and legal advisors were present, Mr. Noto updated the Mobil
Board on the status of the discussions between Exxon and Mobil. The Mobil Board
discussed issues involving a possible merger with Exxon, including the two
companies' differing views on the relative ownership by Mobil and Exxon
shareholders of a combined company. The Mobil Board expressed its support for
Mr. Noto's views in this regard. In addition, Goldman Sachs reviewed additional
possible transactions with large publicly-traded oil companies that might be
considered by Mobil.

     On September 30, 1998, at the regular meeting of the Exxon Board, Mr.
Raymond updated the board on his discussions with Mr. Noto, including the
differing views on relative ownership ranges.  The Exxon Board expressed
its support for Mr. Raymond's views in this regard and encouraged Mr.
Raymond to continue the discussions.  Discussions on possible ownership
ranges continued between Messrs. Raymond and Noto over the next few weeks.

                                                      Chapter One - The Merger


     On October 15, 1998, Mr. Noto updated the Mobil Board on Mobil's strategic
alternatives, the advantages of a combination with Exxon and the status of
discussions between Mobil and Exxon regarding a possible merger. Other
alternatives discussed by Mr. Noto included the possibility of Mobil remaining
an independent company, the possibility of seeking an acquisition candidate, the
possibility of pursuing one or more joint ventures, and the possibility of
seeking to engage in a combination with a company other than Exxon. For the
reasons contained in "Factors Considered by, and Recommendation of, the Mobil
Board" beginning on page I-24 of this proxy statement/prospectus, including that
a transaction with Exxon was more feasible and was expected to yield greater
benefits than the potential alternatives reviewed by Mobil, the Mobil Board
viewed a combination with Exxon as sufficiently superior to other alternatives
to make it worthwhile to continue considering such a transaction. The Mobil
Board discussed the issues regarding a possible merger and authorized Mr. Noto
to continue to pursue discussions with Exxon.

     At a meeting on October 19, 1998 at Exxon's headquarters attended by
Messrs. Raymond, Matthews, Noto and Gillespie, the parties reviewed the possible
relative ownership ranges and expanded the discussions to include such issues as
the representation of current Mobil directors on the board of the combined
company; Mr. Noto's role in the management of the combined company; staffing and
employee issues; the name and principal office locations of the combined
company; and potential termination fees. Messrs. Raymond and Noto concluded that
discussions should be further expanded to cover other terms of a possible
transaction and should involve other senior employees and outside advisors.

     On October 27, 1998, at a regular meeting of the Exxon Board Compensation
Committee to which all non-employee members of the Exxon Board were invited, Mr.
Raymond updated the Exxon Board on the discussions with Mobil. On October 29,
1998, at the regular meeting of the Mobil Board, Mr. Noto updated the Mobil
Board on discussions with Exxon regarding a possible merger.

     On October 28, 1998, Skadden, Arps, Slate, Meagher & Flom LLP, counsel to
Mobil, provided a memorandum to Davis Polk & Wardwell, counsel to Exxon,
outlining certain merger agreement terms proposed by Mobil for the transaction.
The Mobil proposal outlined, among other things: a stock for stock merger in
which the parties would account for the transaction as a pooling of interests;
the representation of Mobil directors on the Exxon board after the merger;
matters relating to the benefits of Mobil employees following the merger;
mechanisms designed to address integration issues; provisions limiting the
conditions to the consummation of a possible transaction and providing for the
payment of termination fees if the merger agreement was terminated or the
transaction was not consummated.

       On November 4, 1998, Davis Polk provided a memorandum to Skadden
outlining Exxon's responses to the proposal submitted by Mobil. On November 5,
representatives of Exxon, Mobil and their counsel met in New York to discuss the
merger agreement and open issues. Significant issues addressed included
composition of the combined company's board and committees of such board,
location of the combined company's headquarters, use of the Mobil brand name,
the role of the transition committee, employee matters, conditions to closing,
circumstances under which a termination fee would be payable, whether Mobil
would grant a stock option to Exxon, and certain representations and warranties
to be included in the merger agreement.

     On October 16, 1998, Exxon informed J.P. Morgan that Exxon was interested
in engaging J.P. Morgan as its financial advisor if discussions with Mobil
regarding a possible transaction reached a more advanced stage. On November 9,
1998, Exxon entered into an engagement letter relating to the retention of J.P.
Morgan as Exxon's financial advisor for the proposed transaction with Mobil.

     During November 1998, Exxon and Mobil exchanged due diligence request lists
and representatives of both companies and their advisors participated in a video
conference and numerous telephone calls and meetings to conduct reciprocal
legal, business, accounting and financial due diligence.  A reciprocal
confidentiality agreement was entered into on November 12.

Chapter One - The Merger


     On November 12, 1998, Davis Polk delivered a first draft of the merger
agreement to Mobil and its counsel. On November 13, Mobil and its counsel
provided written comments on this draft to Exxon and its counsel and in the
following weeks, Exxon and Mobil and their counsel continued to negotiate the
provisions of this agreement. On November 17, a first draft of the stock option
agreement was provided to Mobil and its counsel.

     A meeting was held in Washington, D.C. on November 18, 1998, attended by
Messrs. Raymond and Noto and other senior Exxon and Mobil officers, as well as
outside counsel, to discuss regulatory issues as well as key open issues in the
merger agreement, including closing conditions, payment of termination fees,
employee matters, and the proposed grant by Mobil to Exxon of an option to buy
Mobil stock.

     On November 19, 1998, Messrs. Longwell and Dahan of Exxon met with Mr.
Renna of Mobil in Washington, D.C. to discuss organizational issues for the
combined company, including a proposal to organize the combined company along
functional business lines rather than on the basis of geography.

     Over the weekend of November 21, 1998, drafts of the merger agreement and
the stock option agreement were delivered to the Mobil and Exxon Boards.

     On November 22, 1998, Mobil formalized its retention of Goldman Sachs as
its financial advisor for the proposed transaction with Exxon by entering into
an engagement letter with Goldman Sachs.

     On November 22, 1998, the Mobil Board held a special meeting at which it
was briefed on the status of discussions between Exxon and Mobil and reviewed
the relevant financial, accounting and legal considerations of the proposed
transaction. At the meeting, Goldman Sachs made a preliminary financial
presentation that was similar to the final presentation made at the December 1,
1998 meeting of the Mobil Board. Skadden reviewed the terms and conditions of
the proposed merger agreement and stock option agreement, as well as remaining
open issues, and reviewed with the Mobil Board its fiduciary duties under
Delaware law. In addition, Hogan & Hartson and Linklaters & Alliance, Mobil's
regulatory counsel, presented their analyses of regulatory matters and discussed
related issues with the Mobil Board. Ernst & Young LLP also reviewed with the
Mobil Board accounting matters relating to the proposed merger and issued a
letter to the Mobil Board from E&Y concurring with Mobil's conclusion that the
merger should be accounted for as a pooling of interests. At the conclusion of
the November 22 meeting, the Mobil Board authorized Mobil management to continue
discussions with Exxon regarding a possible merger.

     On November 23, 1998, Mr. Noto telephoned Mr. Raymond to discuss, among
other things, open issues in the merger agreement and the stock option
agreement.

     At the regular meeting of the Exxon Board on November 25, 1998, at which
all of Exxon's directors were present, Exxon's directors were briefed on the
objectives and strategic benefits, both near- and longer-term, from a merger
with Mobil and the possibility of further enhancing shareholder value over what
could be achieved on a stand alone basis, as well as on the status of the
discussions with Mobil. J.P. Morgan presented its preliminary financial analysis
of the merger. PricewaterhouseCoopers LLP discussed accounting matters relating
to the merger and submitted to the Exxon Board a letter from PwC concurring with
Exxon's conclusion that the merger should be accounted for as a pooling of
interests. In addition, Covington & Burling, Exxon's regulatory counsel,
presented its analysis of regulatory matters. Davis Polk reviewed the terms and
conditions of the proposed merger agreement and stock option agreement as well
as remaining open issues, and reviewed the Exxon Board's legal duties and
responsibilities. The Exxon Board authorized Exxon management to continue
discussions with Mobil and to move toward finalizing a merger agreement to
achieve the objectives discussed.

     On November 26, 1998, Mr. Noto and Mr. Raymond spoke by telephone to
discuss reports that had appeared in the media about a possible transaction
between Exxon and Mobil. On November 27, 1998, prior to the opening of NYSE
trading, Exxon and Mobil issued a joint statement confirming that the two
companies were in discussions concerning a possible business combination.

<PAGE>


                                                      Chapter One - The Merger


     Over the course of the weekend of November 27, 1998, Exxon and Mobil
representatives and outside counsel continued discussions towards resolving open
issues. On the evening of November 30, Messrs. Raymond and Noto met and reached
agreement in principle, subject to Board approval, on the remaining unresolved
terms of the merger, including the exchange ratio and the resulting exercise
price in the stock option agreement.

     At a special meeting of the Exxon Board on December 1, 1998, Mr. Raymond
reviewed the near- and longer-term strategic benefits of a merger with Mobil and
the status of the transaction; J.P. Morgan delivered its fairness opinion to the
Exxon Board; and Davis Polk made a presentation on the terms and conditions of
the merger agreement and the stock option agreement and updated the Board on how
remaining open issues had been resolved. After due consideration, the Exxon
Board unanimously approved the merger agreement and the stock option agreement
and the related merger matters described in this document.

     At a special meeting of the Mobil Board held on December 1, 1998 to
consider the merger, the Mobil Board received a financial presentation from and
the fairness opinion of Goldman Sachs. Skadden then reviewed the changes in the
terms of the proposed merger agreement and stock option agreement since the
November 22 meeting. Following these presentations, and a discussion regarding
the strategic benefits of the proposed merger and of the terms and conditions of
the merger agreement and the stock option agreement, the Mobil Board, with one
director voting against, approved the merger agreement and the stock option
agreement and determined to recommend that the Mobil shareholders approve the
merger agreement and the merger.

     Following the approval of their Boards, Exxon and Mobil executed the merger
agreement and the stock option agreement, and issued a joint press release
immediately thereafter prior to the opening of NYSE trading.

Our Reasons for the Merger

     Exxon and Mobil each have a long history of being managed to enhance
shareholder value. Individually, both companies have positive prospects for the
future. However, we believe that by combining the two companies, we can create
substantially more shareholder value than could be achieved by the companies on
their own. This is the fundamental reason for the merger.

     Simply having a bigger company is not a reason for us to merge. To create
shareholder value, the new company must be better. As we explain in more detail
below, we believe that by combining the businesses of Exxon and Mobil we can
save money, increase profits and returns, and reduce risk. We will also have
greater financial, technological, and human resources. This will increase our
ability to handle large, complex, and costly international energy projects.

     The scale and cost structure of the combined company will help us compete
more effectively with the largest firms outside the U.S. These include other
multi-national oil companies which have recently combined or formed joint
ventures, as well as the very large state-owned oil companies which have been
rapidly expanding outside their traditional areas.

     The benefits of the merger fall broadly in two categories: near-term
operating synergies and capital productivity improvements. We believe these
benefits depend on the merger and are not available to the companies on their
own.

     Near-term Operating Synergies.  We believe we can run the combined company
     more efficiently than either company on its own.  Specifically, we expect
     the combined company to achieve about $2.8 billion in annual
     pre-tax benefits from operating synergies. By operating synergies we mean
     increases in production, sales, and efficiency, decreases in unit costs and
     overhead expense, and other benefits made possible by combining
     complementary operations.

                                      I-19

<PAGE>


Chapter One - The Merger


          About two-thirds of these benefits should come from:

            o Streamlining the combined organization, which we can run with less
              administrative and overhead cost than two separate organizations;
              and

            o Eliminating excess capacity, duplicate facilities, and redundant
              operations.

          Additional synergy benefits should come from:

            o Exploring for oil and gas more efficiently in regions where the
              companies operate separately today;

            o Applying each company's best business practices across the
              worldwide operations of the combined company; and

            o Coordinating purchases of raw materials across the two companies'
              extensive supply, refining and chemicals networks.

          We expect to realize the full $2.8 billion in annual pre-tax synergy
     benefits by the third year after the merger. During the first two years,
     the benefits should begin to be realized but will be partly offset by
     one-time costs we estimate at $2 billion. These are non-recurring costs
     that we expect to incur to integrate the businesses. On a net basis, the
     earnings impact should be neutral in the first year after the merger and
     positive by the second year.

     Capital Productivity Improvements. We also believe the combined company can
     use its capital more profitably than either company on its own. As
     discussed below, Exxon Mobil will, by combining complementary assets, have
     a stronger presence in those regions of the world with the best potential
     for future oil and gas discoveries and production. We will also have an
     improved and more balanced presence in high-growth markets and businesses.
     This will provide a broader menu of capital investment opportunities from
     which to choose the best projects to advance. As a result, we believe the
     combined company will be able to maintain or improve earnings while
     spending less on capital projects overall. Additionally, we believe that
     many of our existing assets will perform better when combined due to
     efficiencies of scale, cost savings, and sharing of best management
     practices.

     The businesses and assets of Exxon and Mobil are highly complementary in
key areas. As a result, the combined company should be a top competitor among
international energy companies in all three of its main businesses: exploration
and production, refining and marketing, and chemicals. In terms of both
geography and areas of business, the combined company will also have a more
diverse portfolio. Diversification helps us better spread and manage the risks
inherent in our volatile industry. This means that a downturn in a particular
country or business will have less impact on overall performance.

     Exploration and Production.  The combined company will have an improved
     portfolio in key exploration and production areas of the world today.
     For example:

        o  Exxon's leadership position in deepwater exploration in West Africa
           will combine with Mobil's existing production and exploration acreage
           in Nigeria and Equatorial Guinea;

        o  In the Caspian, Exxon's strong presence in Azerbaijan will combine
           with Mobil's similar position in Kazakhstan, including its
           significant interest in the Tengiz field, and its presence in
           Turkmenistan;

        o  Complementary exploration and production operations also exist in
           South America, Russia and Eastern Canada;

                                                      Chapter One - The Merger


        o  In the higher-growth natural gas business, the companies will combine
           their own leading technologies and large positions in several of the
           world's key markets, including North America, Europe and
           Asia-Pacific.

          On a worldwide basis, the combined company will have proved oil and
     natural gas reserves of 21 billion oil-equivalent barrels.

     Refining and Marketing. In refining operations, the combined company will
     have access to an expanded network of refineries for manufacturing high
     quality fuel products and feedstocks. Both companies have traditionally
     focused on maintaining highly efficient, technologically up-to-date
     refineries. These facilities have good locations and are integrated with
     lubricant or chemical manufacturing facilities, providing additional
     opportunities to improve efficiency.

          In retail marketing, the combined company will benefit from an
     expanded worldwide base of branded service stations, as well as Exxon's and
     Mobil's global brand recognition. By sharing expertise, we expect to
     enhance the combined company's offering of high-quality products and
     services and attractive, efficient store designs.

          In lubricants, Exxon's industry leading basestock manufacturing
     business will combine with Mobil's expertise in synthetic lubricants and
     leading position in worldwide finished product sales.

     Chemicals. On a worldwide basis, the combined company will have a greater
     olefin, polyolefin and paraxylene capacity. This will provide opportunities
     to save money through manufacturing efficiencies. We also believe that a
     common focus on efficiency, use of cost-effective raw materials, and
     further integration of fuels and chemicals operations at individual sites
     will improve overall performance.

     Proprietary Technologies. Exxon and Mobil have each invested in extensive
     research and development programs over the years. As a result, each company
     has its own exclusive patents on valuable technologies. The merger will let
     us share these proprietary technologies and apply them across the combined
     business. For example, in the exploration and production business, we will
     benefit from sharing deepwater, arctic, heavy oil and remote natural gas
     technologies. In the refining and marketing and chemicals businesses, we
     will benefit from sharing catalysis technologies and proprietary processes
     for manufacturing fuels, chemicals, and synthetic lubricants.

     Exxon and Mobil share a number of important long-term corporate values,
including:

        o   A commitment to enhancing shareholder value;

        o   An emphasis on efficiency, investment discipline and asset
            productivity;

        o   A focus on product quality and customer satisfaction; and

        o   A commitment to safety, health and environmental care.

     Both companies also benefit from talented and dedicated employees with a
long-standing commitment to excellence. We believe these shared values will
facilitate a relatively smooth integration of the two companies.

Chapter One - The Merger


Exxon Mobil's Senior Management Team

     Our senior management team is expected to consist of the six individuals
named below. This team reflects that Exxon Mobil will be organized along
business lines with three major business units: * exploration & production *
refining and marketing and * chemicals. A transition committee consisting of Mr.
Raymond and Mr. Noto is responsible for recommending to the Exxon Mobil Board
the other senior officers.

                    Lee R. Raymond                Chairman and CEO
                    Lucio A. Noto                 Vice Chairman
                    Harry J. Longwell             Senior Vice President
                    Rene Dahan                    Senior Vice President
                    Eugene A. Renna               Senior Vice President
                    Robert E. Wilhelm             Senior Vice President

     Mr. Longwell will be responsible for exploration and production. Mr. Dahan
will be responsible for chemicals. Mr. Renna will be responsible for refining
and marketing. All six individuals will be on the Exxon Mobil Board.

Factors Considered by, and Recommendation of, the Exxon Board

     At a meeting of the Exxon Board held on December 1, 1998, after due
consideration, the Exxon Board unanimously:

      (i)  determined that the merger agreement, the merger, the stock option
           agreement, the amendments to Exxon's charter and the related
           transactions are fair to and in the best interests of Exxon and its
           shareholders,

     (ii)  approved the merger agreement, the merger, the stock option
           agreement, the charter amendments and the related transactions, and

    (iii)  determined to recommend that the shareholders of Exxon approve the
           merger, including the issuance of Exxon common stock in the merger,
           and the charter amendments. Accordingly, the Exxon Board recommends
           that the Exxon shareholders vote "FOR" the approval of the merger,
           including the issuance of Exxon common stock in the merger, and the
           charter amendments.

     In approving the transaction and making these recommendations, the Exxon
Board consulted with Exxon's management as well as its outside legal counsel and
financial advisor, and considered the following material factors:

          (1) all the reasons described above under "Our Reasons for the
     Merger", including the near- and longer-term synergies and productivity
     improvements expected to be available to the combined company;

          (2) the possibility, as alternatives to the merger, of pursuing an
     acquisition of or a business combination or joint venture with an entity
     other than Mobil and the Exxon Board's conclusion that a transaction with
     Mobil is more feasible, and is expected to yield greater benefits, than the
     likely alternatives. The Exxon Board reached this conclusion for reasons
     including Mobil's interest in pursuing a transaction with Exxon, Exxon's
     view that the transaction could be acceptably completed from a timing and
     regulatory standpoint, and Exxon management's assessment of the
     alternatives and the expected benefits of the merger and compatibility of
     the companies as described under "Our Reasons for the Merger" above;

                                      I-22

                                                      Chapter One - The Merger


          (3) the fact that Exxon shareholders would hold approximately 70% of
     the outstanding stock of the combined company after the merger;

          (4) comparisons of historical financial measures for Exxon and Mobil,
     including earnings, return on capital employed and cash flow, and
     comparisons of historical operational measures for Exxon and Mobil,
     including hydrocarbon reserve replacement, hydrocarbon production and
     refinery runs;

          (5) current industry, economic and market conditions, including
     current low prices for crude oil and refined products. The Exxon Board
     considered that, when oil prices and refining margins fall, companies must
     improve the performance of their internal operations to maintain
     profitability. The Exxon Board considered it likely that low prices would
     lead to further consolidation in the oil and gas industry because, as
     explained under "Our Reasons for the Merger," combining operations can help
     companies save money and operate more efficiently;

          (6) the intended accounting of the merger as a pooling of interests
     which results in combined financial statements prepared on a basis
     consistent with the underlying view that shareholder interests in the two
     companies have simply been combined, and in the preservation of the
     historical cost approach for both Exxon and Mobil. This will facilitate
     future comparison and benchmarking of Exxon Mobil against our key
     international competitors;

          (7) the ability to complete the merger as a tax-free reorganization
     for U.S. federal income tax purposes;

          (8) the terms and conditions of the merger agreement, including the
     conditions to closing and the termination fees payable under certain
     circumstances (see "The Merger Agreement--Conditions to the Completion of
     the Merger" and "The Merger Agreement--Termination of the Merger
     Agreement");

          (9) the grant to Exxon of an option to acquire Mobil stock exercisable
     under certain circumstances pursuant to the stock option agreement (see
     "The Merger Agreement--Stock Option Agreement");

         (10) the analyses and presentations of J.P. Morgan, and J.P. Morgan's
     written opinion to the effect that, as of December 1, 1998, and based upon
     and subject to the various considerations set forth in its opinion, the
     consideration proposed to be paid by Exxon in the merger was fair from a
     financial point of view to Exxon;

         (11) the role that Exxon's current management would play in the
     management of the combined company and the composition of the combined
     company's Board of Directors;

         (12) the challenges of combining the businesses of two major
     corporations of this size and the attendant risk of not achieving the
     expected cost savings and other benefits, as discussed under "Cautionary
     Statement Concerning Forward-Looking Statements", and of diverting
     management focus and resources from other strategic opportunities and
     operational matters for an extended period of time; and

         (13) that while the merger is likely to be completed, there are risks
     associated with obtaining necessary approvals, and as a result of certain
     conditions to the completion of the merger, it is possible that the merger
     may not be completed even if approved by shareholders (see "The Merger
     Agreement--Conditions to the Completion of the Merger").

     In view of the wide variety of factors considered in connection with its
evaluation of the merger and the complexity of these matters, the Exxon Board
did not find it useful to and did not attempt to quantify, rank or otherwise
assign relative weights to these factors. The Exxon Board relied on the
experience and expertise of J.P. Morgan, its financial advisor, for
quantitative analysis of the financial terms of the merger.  See "Opinions of

                                      I-23

Chapter One - The Merger


Financial Advisors--Opinion of Exxon Financial Advisor".  In addition, the
Exxon Board did not undertake to make any specific determination as to
whether any particular factor, or any aspect of any particular factor, was
favorable or unfavorable to the Exxon Board's ultimate determination, but
rather the Exxon Board conducted an overall analysis of the factors
described above, including through discussions with and questioning of
Exxon's management and legal, financial and accounting advisors.  In
considering the factors described above, individual members of the Exxon
Board may have given different weight to different factors.

     The Exxon Board considered all these factors as a whole, and overall
considered the factors to be favorable to and to support its determination.
However, the general view of the Exxon Board was that factors 12 and 13 were
uncertainties or risks relating to the transaction, and that the other reasons
and factors described above were generally considered favorable.

Factors Considered by, and Recommendation of, the Mobil Board

     At its December 1, 1998 meeting, the Mobil Board, with one director voting
against, determined that the merger agreement and the related transactions,
including the merger, are fair to and in the best interests of Mobil and Mobil's
shareholders. Accordingly, the Mobil Board has adopted the merger agreement,
with one director voting against such adoption, and the Mobil Board recommends
that Mobil's shareholders vote "FOR" approval of the merger agreement and the
merger.

     In the course of reaching its decision to adopt the merger agreement, the
Mobil Board consulted with Mobil's management, as well as its outside legal
counsel and its financial advisor, and considered the following material
factors:

          (1) all the reasons described above under "Our Reasons for the
     Merger", including the near- and longer-term synergies and productivity
     improvements expected to be available to the combined company;

          (2) the risks and potential rewards associated with, as an alternative
     to the merger, continuing to execute Mobil's strategic plan as an
     independent entity. Such risks include, among others, the risks associated
     with remaining independent amidst industry-wide consolidation, and such
     rewards include, among others, the ability of existing Mobil shareholders
     to partake in the potential future growth and profitability of Mobil;

          (3) the possibility, as alternatives to the merger, of seeking to
     acquire another company, seeking to engage in one or more joint ventures or
     seeking to engage in a combination with a company other than Exxon and the
     Mobil Board's conclusion that a transaction with Exxon is more feasible,
     and is expected to yield greater benefits, than the likely alternatives.
     The Mobil Board concluded that a combination with Exxon was more feasible
     than the other alternatives it reviewed for reasons including the fact that
     Exxon was interested in pursuing a transaction with Mobil, and Mobil's view
     that the transaction could be acceptably completed from a timing and
     regulatory standpoint, and would yield greater benefits than the
     alternatives given Exxon's financial strength, and the ability of a
     combined company to fund a greater number of long-term growth projects and
     to compete effectively;

          (4) the value of the exchange ratio provided for in the merger
     agreement relative to the then-current market prices and historical trading
     prices of Mobil and Exxon shares over the past year and relative to the
     stock price premiums paid in mergers of comparable size as discussed in
     Goldman Sachs' selected transaction analysis, that the premium offered in
     the merger was within the range of premiums paid in comparable
     transactions, and that Mobil's shareholders would hold approximately 30% of
     the outstanding stock of the combined company after the merger;

          (5) comparisons of historical financial measures for Mobil and Exxon,
     including earnings, return on capital employed and cash flow, and
     comparisons of historical operational measures for Mobil and Exxon,
     including hydrocarbon reserve replacement, hydrocarbon production and
     refinery runs;

                                                      Chapter One - The Merger


          (6) the prospects of Mobil to compete effectively in the future, the
     prospects of Exxon based on Goldman Sachs' due diligence and its analysis
     of publicly available information including earnings estimates compiled by
     I/B/E/S and First Call, and Mobil management's view, based on its due
     diligence, of Exxon's prospects to compete effectively in the future;

          (7) current industry, economic and market conditions, including
     current low prices for crude oil and refined products. The Mobil Board
     considered that, when oil prices and refining margins fall, companies must
     improve the performance of their internal operations to maintain
     profitability. The Mobil Board considered it likely that low prices would
     lead to further consolidation in the oil and gas industry because, as
     explained under "Our Reasons for the Merger," combining operations can help
     companies save money and operate more efficiently;

          (8) the intended accounting of the merger as a pooling of interests
     which results in combined financial statements prepared on a basis
     consistent with the underlying view that shareholder interests in the two
     companies have simply been combined, and in the preservation of the
     historical cost approach for both Exxon and Mobil. This will facilitate
     future comparison and benchmarking of Exxon Mobil against our key
     international competitors;

          (9) the ability to complete the merger as a tax-free reorganization
     for U.S. federal income tax purposes;

         (10) the terms and conditions of the merger agreement, which include
     restrictions on the conduct of Mobil's business pending closing which
     permit Mobil generally to conduct its business in the ordinary course
     during that period (see "The Merger Agreement");

         (11) the potential effect of the terms of the merger agreement with
     respect to possible third-party proposals to acquire Mobil after execution
     of the merger agreement, including that if any third party made a superior
     proposal (as described under "The Merger Agreement--Termination of the
     Merger Agreement"), the Mobil Board could provide information to and engage
     in negotiations with such third party, subject to the terms and conditions
     of the merger agreement;

         (12) that while the termination payment provisions of the merger
     agreement could have the effect of discouraging alternative proposals for a
     business combination with Mobil and that the stock option agreement could
     prevent an alternative business combination with Mobil from being accounted
     for as a pooling of interests, these provisions would not preclude bona
     fide alternative proposals, and that the size of the termination fee was
     reasonable in light of the size and benefits of the transaction;

         (13) the analyses and presentations prepared by Goldman Sachs, and
     Goldman Sachs' written opinion to the effect that, as of December 1, 1998,
     and subject to the various considerations set forth in its opinion, the
     exchange ratio was fair from a financial point of view to Mobil's
     shareholders;

         (14) the role that Mobil's current management is expected to play in
     the management of the combined company, in particular Mobil management's
     participation in the transition and the intention of Exxon and Mobil to
     take advantage of the best management resources of both companies in Exxon
     Mobil;

         (15) that six of the Mobil Board's members would become directors of
     Exxon Mobil, as described under "The Merger Agreement--Exxon Mobil Board
     and Related Matters";

         (16) that while there would be the expected reduction of workforce
     affecting both Mobil and Exxon employees, Mobil employees would be given a
     fair opportunity to be considered for jobs in the combined company, and
     Mobil employees who were not offered positions in the combined company
     would be

Chapter One - The Merger


     entitled to receive severance benefits under the Mobil severance
     plan described under "Interests of Certain Persons in the Merger" that the
     Mobil Board believed to be fair;

         (17) the fact that while Exxon Mobil's corporate headquarters will be
     located in Irving, Texas, Exxon Mobil's downstream headquarters will be
     located in Fairfax, Virginia;

         (18) that while the merger is likely to be completed, there are risks
     associated with obtaining necessary approvals, and as a result of certain
     conditions to the completion of the merger, it is possible that the merger
     may not be completed even if approved by shareholders (see "The Merger
     Agreement--Conditions to the Completion of the Merger");

         (19) that although, pending completion of the proposed merger, Mobil's
     relationships with customers, governments and partners might be negatively
     affected because of uncertainty surrounding Mobil's future status and
     direction, the Mobil Board believed that any such effect would cease once
     the merger was completed; and

         (20) the interests that certain executive officers and directors of
     Mobil may have with respect to the merger in addition to their interests as
     shareholders of Mobil generally (see "Interests of Certain Persons in the
     Merger").

     In view of the wide variety of factors considered in connection with its
evaluation of the merger and the complexity of these matters, the Mobil Board
did not find it useful to and did not attempt to quantify, rank or otherwise
assign relative weights to these factors. The Mobil Board relied on the
experience and expertise of Goldman Sachs, its financial advisor, for
quantitative analysis of the financial terms of the merger. See "Opinions of
Financial Advisors--Opinion of Mobil Financial Advisor". In addition, the Mobil
Board did not undertake to make any specific determination as to whether any
particular factor, or any aspect of any particular factor, was favorable or
unfavorable to the Mobil Board's ultimate determination, but rather the Mobil
Board conducted an overall analysis of the factors described above, including
through discussions with and questioning of Mobil's management and legal,
financial and accounting advisors. In considering the factors described above,
individual members of the Mobil Board may have given different weight to
different factors.

     The Mobil Board considered all these factors as a whole, and overall
considered the factors to be favorable to and to support its determination.
However, the general view of the Mobil Board was that factor 20 was part of the
general mix of available information without being clearly favorable or
unfavorable, that factors 12, 16, 18 and 19 were uncertainties, risks or
drawbacks relating to the transaction, and that the other reasons and factors
described above were generally considered favorable.

Accounting Treatment

     Exxon and Mobil intend for the merger to be accounted for under the
"pooling of interests" method under the requirements of Opinion No. 16 (Business
Combinations) of the Accounting Principles Board of the American Institute of
Certified Public Accountants, the Financial Accounting Standards Board, and the
rules and regulations of the SEC.

     Exxon has received a letter regarding pooling dated November 25, 1998 from
PwC, its independent accounting firm. The letter states that, as of its date,
based on certain information provided to PwC by Exxon and based on the E&Y
letter described below, PwC concurred with Exxon's conclusion that no conditions
existed which would preclude Exxon from accounting for the merger as a pooling
of interests.

     Mobil has received a letter regarding pooling dated November 22, 1998 from
E&Y, its independent auditing firm. The letter states that, as of its date, E&Y
concurred with Mobil's conclusion that no conditions existed relating to Mobil
that would preclude Exxon from accounting for the merger as a pooling of
interests.

                                                      Chapter One - The Merger


     The receipt of letters from PwC and E&Y dated as of the closing date of the
merger reconfirming their concurrence with the conclusions of Exxon's and
Mobil's managements as to the appropriateness of pooling of interests accounting
treatment is a condition to the closing of the merger.

     Under the pooling of interests accounting method, the reported balance
sheet amounts and results of operations of the separate companies for prior
periods will be combined, reclassified and conformed, as appropriate, to reflect
the combined financial position and results of operations for Exxon Mobil. See
"Unaudited Pro Forma Condensed Combined Financial Statements".

Material Federal Income Tax Consequences of the Merger

     The following discussion summarizes the opinions of Davis Polk & Wardwell
and Skadden, Arps, Slate, Meagher & Flom LLP as to the material federal income
tax consequences of the merger. We have filed these opinions with the SEC as
exhibits to the registration statement related to this joint proxy
statement/prospectus. See "Where You Can Find More Information" on page VI-1.
This discussion is based upon the Internal Revenue Code of 1986, as amended, the
regulations promulgated under the Code, Internal Revenue Service rulings, and
judicial and administrative rulings in effect as of the date hereof, all of
which are subject to change, possibly with retroactive effect. This discussion
does not address all aspects of federal income taxation that may be relevant to
a shareholder in light of the shareholder's particular circumstances or to those
Mobil shareholders subject to special rules, such as shareholders who are not
citizens or residents of the United States, financial institutions, tax-exempt
organizations, insurance companies, dealers in securities, shareholders who
acquired their Mobil stock pursuant to the exercise of options or similar
derivative securities or otherwise as compensation or shareholders who hold
their Mobil stock as part of a straddle or conversion transaction. This
discussion assumes that Mobil shareholders hold their respective shares of Mobil
stock as capital assets within the meaning of Section 1221 of the Code.

     It is a condition to the obligations of Mobil and Exxon to complete the
merger that each receive a legal opinion from its counsel that the merger
constitutes a tax-free reorganization, within the meaning of Section 368 of the
Code, for federal income tax purposes. These legal opinions will assume the
absence of certain changes in the existing facts and may rely on assumptions,
representations and covenants made by Mobil, Exxon and others, including those
contained in certificates of officers of Mobil and Exxon. If any of these
factual assumptions is inaccurate, the tax consequences of the merger could
differ from those described here. The opinions regarding the tax-free nature of
the merger neither bind the IRS nor preclude the IRS from adopting a contrary
position. Neither Mobil nor Exxon intends to obtain a ruling from the IRS with
respect to the tax consequences of the merger.

     Federal Income Tax Consequences to Exxon Shareholders. Holders of Exxon
stock will not recognize any gain or loss for federal income tax purposes as a
result of the merger.

     Federal Income Tax Consequences to Mobil Shareholders. Except as provided
below, holders of shares of Mobil stock will (1) not recognize any gain or loss
for federal income tax purposes as a result of the exchange of their shares of
Mobil stock for Exxon Mobil stock in the merger except with respect to cash
received instead of a fractional share of Exxon Mobil common stock and (2) have
a tax basis in the Exxon Mobil stock received in the merger equal to the tax
basis of the Mobil stock surrendered in the merger less any tax basis of the
Mobil stock surrendered that is allocable to a fractional share of Exxon Mobil
common stock for which cash is received. The Mobil shareholders' holding period
with respect to the Exxon Mobil stock received in the merger will include the
holding period of the Mobil stock surrendered in the merger.

     To the extent that a holder of shares of Mobil common stock receives cash
instead of a fractional share of Exxon Mobil common stock, the holder will be
required to recognize gain or loss for federal income tax purposes,
measured by the difference between the amount of cash received and the portion
of the tax basis of the holder's shares of Mobil common stock allocable to such
fractional share of Exxon Mobil common stock. This gain or loss will be a
capital gain or loss and will be a long-term capital gain or loss if the share
of Mobil common stock exchanged for the fractional share of Exxon Mobil common
stock was held for more than one year at the effective time of the merger.

     Under the merger agreement, Mobil will pay any transfer taxes incurred as a
result of a change in ownership of Mobil, including transfer taxes that under
applicable law may be the primary liability of the holders of Mobil stock.
Although the matter is not free from doubt (because of the absence of
legislative, judicial or other authority directly on point), Mobil's payment of
transfer taxes for which the Mobil shareholders are primarily liable, if any,
may be taxable as a dividend to the Mobil shareholders for federal income tax
purposes.

     Federal Income Tax Consequences to Mobil, Exxon and the Merger Subsidiary.
None of Exxon, Mobil, or the merger subsidiary will recognize gain or loss for
federal income tax purposes as a result of the merger.

     WE INTEND THIS DISCUSSION TO PROVIDE ONLY A SUMMARY OF THE MATERIAL FEDERAL
INCOME TAX CONSEQUENCES OF THE MERGER. WE DO NOT INTEND THAT IT BE A COMPLETE
ANALYSIS OR DESCRIPTION OF ALL POTENTIAL FEDERAL INCOME TAX CONSEQUENCES OF THE
MERGER. IN ADDITION, WE DO NOT ADDRESS TAX CONSEQUENCES WHICH MAY VARY WITH, OR
ARE CONTINGENT UPON, INDIVIDUAL CIRCUMSTANCES. MOREOVER, EXCEPT FOR THE
DISCUSSION OF TRANSFER TAXES ABOVE, WE DO NOT ADDRESS ANY NON-INCOME TAX OR ANY
FOREIGN, STATE OR LOCAL TAX CONSEQUENCES OF THE MERGER. ACCORDINGLY, WE STRONGLY
URGE YOU TO CONSULT YOUR TAX ADVISOR TO DETERMINE YOUR PARTICULAR UNITED STATES
FEDERAL, STATE, LOCAL OR FOREIGN INCOME OR OTHER TAX CONSEQUENCES RESULTING FROM
THE MERGER, WITH RESPECT TO YOUR INDIVIDUAL CIRCUMSTANCES.

Regulatory Matters

     U.S. Antitrust. Under the Hart-Scott-Rodino Antitrust Improvements Act of
1976, as amended, and the related rules the merger may not be completed until
notifications have been given, certain information has been furnished to the FTC
and specified waiting period requirements have been satisfied. During the week
of December 14, 1998 Exxon and Mobil each filed the required notification and
report forms under the HSR Act with the FTC and the Antitrust Division of the
United States Department of Justice. On January 15, 1999, the FTC issued a
request for additional information and other documentary materials to Exxon and
Mobil relating to the merger. The merger may not be completed until 20 days
following substantial compliance with this request by both parties, unless the
waiting period is terminated earlier. If it believes that the merger would
violate the federal antitrust law by substantially lessening competition in any
line of commerce affecting U.S. consumers, the FTC has the authority to
challenge the merger on antitrust grounds by seeking a federal court order
temporarily enjoining the transaction pending conclusion of an administrative
hearing. The FTC may also proceed with an administrative proceeding if the
injunction is denied, and if the merger is found to be anticompetitive,
challenge it after the fact. We can give no assurance that a challenge to the
merger will not be made or, if such a challenge is made, that it would be
unsuccessful. In addition, a number of state attorneys general have indicated
their intent to review the proposed merger and to coordinate that review with
the FTC. Expiration or termination of the HSR Act waiting period is a condition
to the merger. See "The Merger Agreement--Conditions to the Completion of the
Merger" on page I-58.

     European Union. Under Council Regulation No. 4064/89 of the European
Commission and accompanying regulations, the merger is subject to review by the
European Commission. Exxon and Mobil informally notified the EC of the merger on
December 1, 1998 and expect to file formal notifications with the EC of the
merger agreement by the end of April 1999. Completion of review under the EC
merger regulation is a condition to the merger. See "The Merger
Agreement--Conditions to the Completion of the Merger" on page I-58.

     Other Laws. Exxon and Mobil conduct operations in a number of jurisdictions
where other regulatory filings or approvals may be required or advisable in
connection with the completion of the merger. Exxon and Mobil are currently in
the process of reviewing whether other filings or approvals may be required or
desirable in these other jurisdictions.  We recognize that some of these
filings may not be completed before the closing, and that some of these
approvals, which are not as a matter of practice required to be obtained
prior to effectiveness of a merger transaction, may not be obtained prior
to the closing.

     General. It is possible that governmental entities having jurisdiction over
Exxon and Mobil may seek regulatory concessions as conditions for granting
approval of the merger. If any regulatory body's approval contains terms or
imposes conditions or restrictions relating or applying to, or requiring changes
in or limitations

                                                      Chapter One - The Merger


on, the operation or ownership of any asset or business of Exxon, Mobil or
any of their subsidiaries, or on Exxon Mobil's ownership of Mobil or
requiring asset divestitures, which could reasonably be expected to result
in a substantial detriment to Exxon, Mobil and their subsidiaries, taken as
a whole, after the closing, Exxon can decline to close under the merger
agreement.  We can give no assurance that the required regulatory approvals
will be obtained on terms that satisfy the conditions to closing of the
merger or within the time frame contemplated by Exxon and Mobil.  See "The
Merger Agreement--Conditions to the Completion of the Merger" on page I-58.

Appraisal Rights

     Holders of Exxon common stock are not entitled to dissenters' appraisal
rights under New Jersey law in connection with the merger. Holders of Mobil
common stock do not have dissenters' appraisal rights under Delaware law in
connection with the merger because the shares of Exxon Mobil common stock that
such holders will be entitled to receive in the merger will be listed on the New
York Stock Exchange at the closing. See "Chapter Three--Comparison of
Shareholder Rights--Appraisal Rights". Dissenters' appraisal rights are
available in connection with the merger to the trustee of the Mobil ESOP, the
sole record holder of Mobil ESOP preferred stock, if the trustee complies with
the procedural requirements of the Delaware dissenters' rights statute.

Federal Securities Laws Consequences; Stock Transfer Restriction Agreements

     This joint proxy statement/prospectus does not cover any resales of the
Exxon Mobil common stock to be received by the shareholders of Mobil upon
completion of the merger, and no person is authorized to make any use of this
joint proxy statement/prospectus in connection with any such resale.

     All shares of Exxon Mobil common stock received by Mobil shareholders in
the merger will be freely transferable, except that shares of Exxon Mobil common
stock received by persons who are deemed to be "affiliates" of Mobil under the
Securities Act of 1933, as amended, at the time of the Mobil meeting may be
resold by them only in transactions permitted by Rule 145 under the 1933 Act or
as otherwise permitted under the 1933 Act. Persons who may be deemed to be
affiliates of Mobil for such purposes generally include individuals or entities
that control, are controlled by or are under common control with Mobil and
include directors and executive officers of Mobil. The merger agreement requires
Mobil to use its reasonable best efforts to cause each of such affiliates to
execute a written agreement to the effect that such persons will not offer, sell
or otherwise dispose of any of the shares of Exxon Mobil common stock issued to
them in the merger in violation of the 1933 Act or the related SEC rules.

     In addition, each of the directors and some of the executive officers of
Exxon and Mobil have executed written agreements prohibiting them from selling,
transferring or otherwise disposing of, or acquiring or selling any options or
other securities relating to, securities of Exxon or Mobil that would be
intended to reduce the individual's risk relative to, any shares of Exxon common
stock or Mobil common stock beneficially owned by him or her during the period
beginning 30 days prior to the closing and ending at such time as financial
results covering at least 30 days of combined operations of Exxon and Mobil have
been publicly released by Exxon Mobil after the merger.

     On November 25, 1998, the last full trading day before Exxon and Mobil
issued a joint press release confirming that they were in discussions concerning
a possible combination, the last reported per share closing price was $72.688
for Exxon common stock and $78.375 for Mobil common stock. On November 30, 1998,
the last full trading day before the public announcement of the proposed merger,
the last reported closing price was $75.000 for Exxon common stock and $86.000
for Mobil common stock. On April 1, 1999, the most recent practicable date prior
to the printing of this joint proxy statement/prospectus, the last reported

stock. We urge you to obtain current market quotations prior to making any
decision with respect to the merger.

     Following the merger, Exxon Mobil common stock will be traded on the NYSE
under the ticker symbol "XOM".

     The merger agreement permits Exxon and Mobil to pay, prior to the closing,
regular quarterly cash dividends to holders. The parties have agreed in the
merger agreement to coordinate declaring dividends and the related record dates
and payment dates so that Mobil shareholders do not receive two dividends, or
fail to receive one dividend, for any single calendar quarter with respect to
their Mobil shares and the Exxon Mobil shares to be received by them in the
merger.

                                                      Chapter One - The Merger


     Exxon Mobil expects to continue to pay quarterly dividends on Exxon Mobil
common stock after completion of the merger. The payment of dividends by Exxon
Mobil in the future, however, will depend on business conditions, Exxon Mobil's
financial condition and earnings and other factors.

Effect of Merger on Mobil Dividend Reinvestment Plan

     Upon completion of the merger, Mobil's Stock Purchase and Dividend
Reinvestment Plan (the "Mobil DRIP") will terminate and participants in the plan
will be automatically enrolled in Exxon Mobil's Shareholder Investment Program
(the "Exxon Mobil SIP"). Exxon Mobil shares issued in exchange for Mobil DRIP
shares will be held in book-entry form by the administrator of the Exxon Mobil
SIP and cash dividends paid by Exxon Mobil on those shares will be reinvested in
additional Exxon Mobil shares. Participants in the Exxon Mobil SIP can obtain
certificates for their plan shares, change dividend reinvestment levels, or
withdraw from the plan by following specified procedures. Mobil DRIP
participants will receive more information on the Exxon Mobil SIP as soon as
practicable after completion of the merger.

Chapter One - The Merger


           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.

     We are providing the following information to aid you in your analysis of
the financial aspects of the merger. We derived this information from the
audited financial statements of Exxon for the years 1998, 1997 and 1996 and from
the audited financial statements of Mobil for the years 1998, 1997 and 1996. The
information is only a summary and you should read it in conjunction with our
historical financial statements and related notes contained in the annual
reports and other information that we have filed with the SEC and incorporated
by reference. See "Where You Can Find More Information" on page VI-1.

     The unaudited pro forma condensed combined statements of income for the
years ended December 31, 1998, 1997 and 1996 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 December 31, 1998. The accounting
policies of Exxon and Mobil are substantially comparable. Consequently, we did
not make adjustments to the unaudited pro forma condensed combined financial
statements to conform 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. You should not rely on the pro forma combined financial information as
being indicative of the historical results that would have been achieved had the
companies always been combined or the future results that the combined company
will experience after the merger.

      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. The unaudited pro forma condensed combined
balance sheet is based on the consolidated financial statements of Exxon and
Mobil at December 31, 1998.

     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, we did not make adjustments to the unaudited pro forma condensed
combined financial statements to conform the accounting policies of the
combining companies.

     Certain revenues, costs and other deductions in the consolidated statements
of income for Mobil have been reclassified to conform to the line item
presentation in the pro forma condensed combined statements of income. Certain
assets and liabilities 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 Exxon Mobil 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 Exxon Mobil 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

     Merger-related fees and expenses, consisting primarily of SEC filing fees,
fees and expenses of investment bankers, attorneys and accountants, and
financial printing and other related charges, are estimated to be approximately
$90 million. These fees and expenses have been reflected in the unaudited pro
forma condensed combined balance sheet as of December 31, 1998. These charges
are not reflected in the unaudited pro forma condensed combined statements of
income or the pro forma combined per share data.

                                      I-37

Chapter One - The Merger


     We estimate that costs of approximately $2.0 billion ($1.3 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 the obligations occur.

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 Exxon Mobil common stock in exchange
   for all of the outstanding Mobil common stock (based on the exchange ratio
   of 1.32015). The actual number of shares of Exxon Mobil common stock to be
   issued in connection with the merger will be based on the number of shares
   of Mobil common stock issued and outstanding at the effective time.

                         OPINIONS OF FINANCIAL ADVISORS

     We each retained our own financial advisor to assist us and our Boards in
our consideration of valuation, financial and other matters relating to the
merger. Exxon retained J.P. Morgan Securities Inc. as its financial advisor and
Mobil retained Goldman, Sachs & Co. as its financial advisor.

Opinion of Exxon Financial Advisor

     At the December 1, 1998 meeting of the Exxon Board, J.P. Morgan gave its
opinion to the Exxon Board that, as of such date and based upon and subject to
the various considerations set forth in its opinion, the consideration to be
paid by Exxon in connection with the proposed merger was fair from a financial
point of view to Exxon. J.P. Morgan has reaffirmed its December 1, 1998 opinion
in its written opinion to the Exxon Board dated as of April 2, 1999.

     The full text of the updated opinion of J.P. Morgan, which sets forth among
other things the assumptions made, procedures followed, matters considered and
limitations on the scope of the review undertaken by J.P. Morgan in rendering
its opinion, is attached as Annex C and is incorporated by reference with the
consent of J.P. Morgan. This opinion should be read carefully and in its
entirety. J.P. Morgan's opinion is addressed to the Exxon Board, is directed
only to the fairness of the consideration to be paid in the merger, does not
address any other aspect of the merger and does not constitute a recommendation
to any Exxon shareholder as to how to vote with respect to the merger. The
summary of the opinion of J.P. Morgan set forth in this joint proxy
statement/prospectus is qualified in its entirety by reference to the full text
of such opinion.

     In rendering its opinions, J.P. Morgan reviewed:

        o  the merger agreement;

        o  in the case of its updated opinion, this document;

        o  certain publicly available information concerning the business of
           Mobil and of certain other companies engaged in businesses that J.P.
           Morgan deemed comparable to those of Mobil, and the reported market
           prices for the securities of certain other companies that J.P. Morgan
           deemed comparable;

        o  publicly available terms of certain transactions involving companies
           comparable to Mobil and the consideration received for such
           companies;

        o  current and historical market prices of the Exxon common stock and
           the Mobil common stock;

        o  the audited financial statements of Exxon and Mobil for the fiscal
           year ended December 31, 1997, and the unaudited condensed financial
           statements of Exxon and Mobil for the period ended September 30,
           1998;

        o  in the case of its updated opinion, the audited financial statements
           of Exxon and Mobil for the fiscal year ended December 31, 1998;

        o  certain presentations made by Exxon and Mobil in 1998 to equity
           analysts regarding the performance of their respective businesses;

        o  certain internal financial analyses of potential synergies that may
           be realized from the merger prepared by Exxon and Mobil and their
           respective managements; and

        o  the terms of other business combinations that J.P. Morgan deemed
           relevant.

Chapter One - The Merger


     In addition, J.P. Morgan participated in discussions with certain members
of the management of Exxon and Mobil with respect to certain aspects of the
merger, the past and current business operations of Exxon and Mobil, the
financial condition and future prospects and operations of Exxon and Mobil, and
certain other matters J.P. Morgan believed necessary or appropriate to its
inquiry. J.P. Morgan reviewed such other financial studies and analyses and
considered such other information as it deemed appropriate for the purposes of
its opinion.

     In giving its opinion, J.P. Morgan relied upon and assumed, without
independent verification, the accuracy and completeness of all information that
was publicly available or was furnished to it by Exxon and Mobil or otherwise
reviewed by J.P. Morgan, and J.P. Morgan has not assumed any responsibility or
liability therefor. J.P. Morgan has not conducted any evaluation or appraisal of
any assets or liabilities, nor have any such valuations or appraisals been
provided to J.P. Morgan. In relying on financial analyses provided to it of
potential synergies that may be realized from the merger, J.P. Morgan has
assumed that they have been reasonably prepared based on assumptions reflecting
the best currently available estimates and judgments by management of Exxon as
to such potential synergies. J.P. Morgan has also assumed that the merger will
have the tax consequences and pooling of interests accounting treatment
described in the merger agreement and this document, and that the transactions
contemplated by the merger agreement will be consummated as described in the
merger agreement and this document. J.P. Morgan relied as to all legal matters
relevant to rendering its opinion upon the advice of counsel.

     J.P. Morgan's opinion is necessarily based on economic, market and other
conditions as in effect on, and the information made available to J.P. Morgan as
of, the date of such opinion. Subsequent developments may affect its opinion,
and J.P. Morgan does not have any obligation to update, or revise or reaffirm
such opinion. J.P. Morgan expressed no opinion as to the price at which Exxon
common stock will trade at any future time.

     In accordance with customary investment banking practice, J.P. Morgan
employed generally accepted valuation methods in reaching its opinion. The
following is a summary of the material financial analyses utilized by J.P.
Morgan in connection with providing its December 1, 1998 opinion. J.P. Morgan
utilized substantially the same types of analyses in connection with providing
its updated opinion.

     The elements of J.P. Morgan's analyses included:

        o  assessing the potential value creation as a result of the merger
           (paragraphs 1-3);

        o  assessing the sharing of the combined pro forma entity given the
           historical and forecast contributions of each company, and the
           sharing of the potential value creation (paragraphs 4-6);

        o  testing the results on pro-forma Exxon earnings per share for the
           potential accretion/dilution of earnings for the next 3 years
           (paragraph 7); and

        o  checking the premium to be paid by Exxon in the merger against market
           precedent (paragraph 8).

       1.  Comparable Return on Capital Employed. J.P. Morgan reviewed and
analyzed the return on capital employed ("ROCE") of both Exxon and Mobil since
1993. J.P. Morgan observed that Exxon's ROCE has consistently been 2-3% above
that of Mobil. J.P. Morgan's analysis indicated that if Mobil were to be merged
with Exxon, the combined entity's capital productivity would eventually be
higher than the pro forma capital productivity of Exxon and Mobil. J.P. Morgan
indicated that it would be reasonable to assume that the benefits of this
capital productivity increase would occur within three years of the closing of
the merger. J.P. Morgan pointed out, however, that its views in this respect
were based on discussions with senior management at Exxon and that there could
be no assurance that this increase in capital productivity would be realized.

       2. Comparable P/E Analysis. J.P. Morgan performed an analysis comparing
Exxon's price to earnings multiples with Mobil's price to earnings multiples for
the past five years.  The source for these price to earnings multiples was
the one and two year prospective price to earnings multiple estimates by
I/B/E/S International Inc. and First Call, organizations which compile
brokers' earnings estimates on public companies.  Such analysis

                                      I-40

                                                      Chapter One - The Merger


indicated that Mobil has been trading in the recent past at an 8% to 15%
discount to Exxon.  J.P.  Morgan's analysis indicated that if Mobil were to
be valued at price to earnings multiples comparable to those of Exxon,
there would be an enhancement of value to its shareholders of approximately
$11 billion.  Finally, this analysis suggested that the combined company
might enjoy an overall increase in its price to earnings multiple due to
the potential for improved capital productivity and the expected strategic
benefits of the merger.  According to J.P.  Morgan's analysis, a price to
earnings multiple increase of 1 for Exxon Mobil would result in an
enhancement of value to shareholders of approximately $10 billion.  J.P.
Morgan pointed out, however, that there could be no assurance that these
values would be realized.

       3. Annual Pre-Tax Synergies. J.P. Morgan reviewed and analyzed the future
synergies expected to result from the merger, estimated by management at $2.8
billion annually on a pre-tax basis. J.P. Morgan also analyzed stock-for-stock
merger transactions over the past three years where the market capitalization of
the smaller entity pre-announcement was greater than $5 billion. The analysis
indicated that for industrially logical mergers, the market granted a
post-announcement value pick-up to the companies of 6-9 times the anticipated
synergy benefits identified by management on a pre-tax basis. In cases where
management also had a good track record of cost cutting, J.P. Morgan indicated
that the market might be expected to capitalize synergies at a multiple of 8-9
times on a pre-tax basis. Based on the estimated synergies of $2.8 billion
expected to result from the merger, this suggested a potential value creation in
the short term of approximately $22-25 billion.

     J.P. Morgan also indicated that the value of the potential synergies for
the combined company could be greater in the long term if management achieved
its stated objectives and the expected synergies were demonstrated to the
market. On this basis, J.P. Morgan estimated that as much as $11 billion in
value could be created in excess of the short term impact, in addition to the
potential enhancement of value described in paragraph 2 above.

     In addition to expressing no opinion as to the potential future trading
price of the Exxon common stock, J.P. Morgan also pointed out that there could
be no assurance that either these short-term or long-term values would be
realized.

       4. Sharing of Future Benefits of the Merger. J.P. Morgan reviewed the
elements of potential value creation, which were:

     o  immediate value pick-up based on estimated pre-tax synergies; and
     o  additional long-term value pick-up that could result from the possible
        o  realization of anticipated synergies,
        o  price to earnings multiple re-rating for Mobil, and
        o  price to earnings multiple re-rating for the combined company.

J.P. Morgan's review suggested that over the long term, the potential for value
creation from these elements could be as much as $47-57 billion. Since Exxon's
market capitalization is significantly larger than Mobil's, Exxon's shareholders
would enjoy a greater proportion of the value creation if no premium were paid
by Exxon in the merger. By offering a premium to Mobil's shareholders, this
potential value creation was instead shared in approximately equal proportions
between the companies' shareholders and such sharing was deemed to be a
reasonable allocation of value creation.

</TABLE>

     J.P. Morgan observed that the relative contribution by Exxon to a combined
Exxon Mobil entity in the most recent full year of Exxon would have been between
61% and 73% depending on the measure used. J.P. Morgan compared this range of
relative contribution with the approximately 70% continuing ownership stake that
Exxon's shareholders would have in the combined company following the merger.
Sources for the historical financial information used in connection with the
ratios were Exxon's and Mobil's annual reports for the years 1992-1997,
inclusive, and first nine months results of 1998 as announced by both companies.

       6. Forecast Contribution Analysis. J.P. Morgan reviewed and analyzed the
then most current First Call earnings and after-tax operating cash flow
forecasts for 1998, 1999 and 2000.  J.P.  Morgan observed that Exxon was
forecast to contribute between 70% and 73% of the future earnings and cash
flow of a combined Exxon Mobil

entity.  J.P.  Morgan compared this range of forecasted contribution with
the approximately 70% continuing ownership stake that Exxon's shareholders
would have in the combined company following the merger.

       7. Exxon Pro Forma Merger Analysis. J.P. Morgan analyzed the then-current
pro forma Exxon earnings per share forecasts for 1999, 2000 and 2001 based on
First Call estimates. The analysis showed, assuming $2.8 billion in synergies
phased in over three years, on an equivalent share basis, that the merger would
be accretive from 1999 to Exxon's shareholders, excluding non-recurring
integration-related costs.

       8. Analysis of Selected Comparable Transactions. J.P. Morgan reviewed 38
recently announced or closed large capitalization stock-for-stock transactions.
J.P. Morgan then compared the implied premiums resulting from the smaller
company's share of the pro forma combined company resulting from the transaction
as compared with the smaller company's market capitalization relative to the
combined market capitalization of the companies prior to announcement of the
transaction.

     J.P. Morgan's analysis showed that for transactions involving smaller
companies with a relative market capitalization comparable to that of Mobil
pre-announcement, a premium of 15% to 25% matched market precedent. The analysis
indicated that, based on the closing share prices on November 30, 1998, the day
prior to announcement of the merger, the implied premium paid to Mobil
shareholders would be approximately 10%. The analysis also indicated that, based
on closing share prices on November 24, 1998, two trading days before Exxon and
Mobil issued a joint press release confirming that they were in discussions
concerning a possible merger, the implied premium paid to Mobil shareholders
would be approximately 20%.

     The summary set forth above is not a complete description of the analyses
or data presented by J.P. Morgan. The preparation of a fairness opinion is a
complex process and is not necessarily susceptible to partial analysis or
summary description. In arriving at its opinion, J.P. Morgan considered the
results of all of its analyses as a whole and did not attribute any particular
weight to any analysis or factor considered by it. Furthermore, J.P. Morgan
believes that selecting any portion of its analyses, without considering all
analyses, would create an incomplete view of the process underlying its opinion.
In addition, J.P. Morgan may have given various analyses and factors more or
less weight than other analyses and factors, and may have deemed various
assumptions more or less probable than other assumptions, so that the ranges of
valuation resulting from any particular analysis described should not be taken
as J.P. Morgan's view of the actual value of Exxon or Mobil. In performing its
analyses, J.P. Morgan made numerous assumptions with respect to industry
performance, general business and economic conditions and other matters, many of
which are beyond the control of Exxon and Mobil. Any estimates contained in J.P.
Morgan's analyses are not necessarily indicative of future results or actual
values, which may be significantly more or less favorable than those suggested
by such estimates.

     As a part of its investment banking business, J.P. Morgan and its
affiliates are continually engaged in the valuation of businesses and their
securities in connection with mergers and acquisitions, investments for passive
and control purposes, negotiated underwritings, secondary distributions of
listed and unlisted securities, private placements, and valuations for estate,
corporate and other purposes. J.P. Morgan was selected to advise Exxon and to
deliver a fairness opinion with respect to the merger on the basis of such
experience and its familiarity with Exxon.

     Pursuant to a letter agreement dated November 9, 1998, Exxon engaged J.P.
Morgan as its exclusive financial advisor in connection with the merger.
Pursuant to the terms of the J.P. Morgan engagement letter, Exxon has agreed to
pay J.P. Morgan a fee equal to (i) $100,000 per month and (ii) $8,000,000
payable upon the consummation of the merger or acquisition of a majority of the
common stock or assets of Mobil by Exxon, with up to $2,400,000 of the fees paid
pursuant to clause (i) above to be creditable to any fees that become payable
pursuant to clause (ii) above. In addition, Exxon has agreed to reimburse J.P.
Morgan for its reasonable expenses incurred in connection with its services,
including the fees and disbursements of counsel, and will indemnify J.P. Morgan
against certain liabilities arising out of J.P. Morgan's engagement, including
liabilities under the federal securities laws.  The SEC has taken the
position that such indemnification under the federal securities laws may
not be enforceable if it is found to be against public policy.

Chapter One - The Merger


     J.P. Morgan has in the past provided financial advisory services to a
subsidiary of Exxon, and in the past has provided financial advisory and other
services to Mobil. In addition, Mr. Raymond has been a member of J.P. Morgan's
board of directors since 1987. As a result, a potential conflict of interest
could be deemed to exist. The Exxon Board did not consider this potential
conflict to be significant either to the selection of J.P. Morgan as financial
advisor or to relying on J.P. Morgan's opinion. In the ordinary course of their
businesses, J.P. Morgan and its affiliates may actively trade the debt and
equity securities of Exxon or Mobil for their own account or for the accounts of
customers and, accordingly, they may at any time hold long or short positions in
such securities.

Opinion of Mobil Financial Advisor

     On December 1, 1998, Goldman Sachs delivered its written opinion to the
Mobil Board that, as of the date of such opinion, the exchange ratio pursuant to
the merger agreement was fair from a financial point of view to the holders of
Mobil common stock. Goldman Sachs reconfirmed its December 1, 1998 opinion by
delivery of its written opinion dated as of April 2, 1999.

     The full text of the written opinion of Goldman Sachs, dated April 2, 1999,
which sets forth assumptions made, matters considered and limitations on the
review undertaken in connection with the opinion is attached as Annex D and is
incorporated by reference. Mobil shareholders are urged to, and should, read
such opinion in its entirety.

     In connection with its opinion, Goldman Sachs reviewed, among other things:

        o   the merger agreement;

        o   the stock option agreement;

        o   Annual Reports to Stockholders and Annual Reports on Form 10-K of
            Mobil and Exxon for the five years ended December 31, 1997 and, in
            the case of its reconfirmed opinion, the Annual Reports on Form 10-K
            of Mobil and Exxon for the year ended December 31, 1998 and this
            document;

        o   certain interim reports to shareholders and Quarterly Reports on
            Form 10-Q of Mobil and Exxon;

        o   certain other communications from Mobil and Exxon to their
            respective shareholders;

        o   certain internal financial analyses and forecasts for Mobil prepared
            by its management; and

        o  certain cost savings and operating synergies projected by the
           managements of Mobil and Exxon to result from the merger.

     Goldman Sachs also held discussions with members of the senior management
of Mobil regarding the strategic rationale for, and the potential benefits of,
the merger and Mobil's past and current business operations, financial condition
and future prospects. Goldman Sachs reviewed forecasts regarding selected
measures of future operating and financial performance of Exxon in summary form
prepared by management of Mobil based on its discussions with management of
Exxon. Internal financial analyses and forecasts prepared by Exxon were not
otherwise made available for review by Goldman Sachs. In addition, Goldman
Sachs:

        o  reviewed the reported price and trading activity for Mobil common
           stock and Exxon common stock;

        o  compared certain financial and stock market information for Mobil and
           Exxon with similar information for certain other companies the
           securities of which are publicly traded;

        o  reviewed the financial terms of certain recent business combinations;
           and

        o  performed such other studies and analyses as it considered
           appropriate.

     Goldman Sachs relied upon the accuracy and completeness of all of the
financial and other information reviewed by it and assumed such accuracy and
completeness for purposes of rendering its opinion. In that regard, Goldman
Sachs assumed, with the consent of the Mobil Board, that the synergies were
reasonably prepared on a basis reflecting the best available estimates and
judgments of Mobil and Exxon as of the date of its opinion. Goldman Sachs also
assumed, with the consent of the Mobil Board, that the merger will be accounted
for as a pooling of interests under generally accepted accounting principles.
Goldman Sachs also has assumed that all material governmental, regulatory or
other consents and approvals necessary for the completion of the merger will be
obtained without any meaningful adverse effect on Mobil or Exxon. In addition,
Goldman Sachs did not make an independent evaluation or appraisal of the assets
and liabilities of Mobil or Exxon or any of their subsidiaries and Goldman Sachs
was not furnished with any such evaluation or appraisal. The opinion of Goldman
Sachs was provided for the information and assistance of the Mobil Board in
connection with its consideration of the merger and is not a recommendation as
to how any holder of shares of Mobil common stock should vote.

     The following is a summary of the material financial analyses used by
Goldman Sachs in connection with providing its written opinion to the Mobil
Board on December 1, 1998. Goldman Sachs utilized substantially the same types
of financial analyses in connection with providing its opinion dated April 2,
1999.

       1. Historical Stock Trading Analysis. Goldman Sachs reviewed the average
historical trading prices for the shares of Mobil common stock. In addition,
Goldman Sachs analyzed the consideration to be received by holders of Mobil
common stock pursuant to the merger agreement in relation to the average per
share closing price of Mobil common stock for the one week, one month, three
month, six month, one year, three year, five year and ten year periods ended
November 24, 1998 and in relation to the closing price of Mobil common stock on
November 24, 1998 and November 30, 1998. November 24, 1998 was chosen as a
reference date because it was the last trading day prior to public reports that
Mobil and Exxon were discussing a potential business combination transaction.

     This analysis was based on the exchange ratio of 1.32015 and the per share
price of Exxon common stock of $75.00 on November 30, 1998, the last trading day
prior to the announcement of the execution of the merger agreement. The analysis
indicated that the consideration per share of Mobil common stock to be received
by holders of Mobil common stock pursuant to the merger agreement:

        o  in relation to the average closing price for the one week, one month,
           three month, six month and one year periods ending November 24, 1998,
           represented a premium of 33.4%, 33.6%, 31.5%, 32.5% and 33.4%,
           respectively;

        o  in relation to the closing price of Mobil common stock on November
           24, 1998 and November 30, 1998, represented a premium of 32.1% and
           15.1%, respectively; and

        o  in relation to the closing price of Mobil common stock on May 1,
           1998, the date of Mobil's all time high closing stock price prior to
           November 25, 1998, represented a premium of 19.9%.

       2. Exchange Ratio Analysis. Goldman Sachs calculated the average of the
historical daily exchange ratios of Exxon common stock to Mobil common stock
based on the closing prices of Exxon common stock and Mobil common stock for the
one week, one month, three month, six month and one year periods ended November
24, 1998. Such analysis indicated:

        o  that the average exchange ratios over such periods were 1.041, 1.035,
           1.064, 1.059 and 1.096, respectively, compared to the exchange ratio
           of 1.32015 pursuant to the merger agreement;

        o  that the average exchange ratio since the closing price of Mobil
           common stock on May 1, 1998, the date of Mobil's all time high
           closing price prior to November 25, 1998, was 1.092; and

Chapter One - The Merger


        o  an exchange ratio of 1.147 for the closing price of Exxon common
           stock to Mobil common stock on November 30, 1998, as compared to the
           exchange ratio of 1.32015 pursuant to the merger agreement.

       3. Contribution Analysis. Goldman Sachs reviewed certain historical and
estimated future operating and financial information, including, among other
things, equity market value, levered value, total assets, shareholders' equity,
earnings before interest, taxes, depreciation and amortization ("EBITDA"), net
income and discretionary cash flow for Exxon, Mobil and the pro forma combined
company resulting from the merger. Levered value is market value of equity plus
book value of debt less cash. Discretionary cash flow is net income plus
depreciation, depletion, amortization, deferred taxes and exploration expenses.
This analysis indicated that, excluding shares of Mobil common stock held in
trust pursuant to the Trust Agreement, dated June 29, 1992, as amended, between
Mobil and Bankers Trust (Delaware), holders of Mobil common stock would receive
30% of the outstanding common equity of the pro forma combined company after the
merger based on the exchange ratio of 1.32015 and contribute 25%, 26%, 31% and
34% of the equity market value, levered value, total assets and 1997 EBITDA of
the pro forma combined company, respectively.

     Goldman Sachs also analyzed the relative income statement contribution of
Mobil and Exxon to the pro forma combined company resulting from the merger,
before taking into account any of the possible benefits that may be realized
following the merger, for 1997 and estimated years 1998, 1999 and 2000, based on
I/B/E/S International Inc. estimates of earnings and cash flows.

     The results of these analyses are as follows:

Discretionary Cash Flow.................    32%      29%      31%       33%
</TABLE>

       4. Selected Companies Analysis. Goldman Sachs reviewed and compared
certain financial information, ratios and public market multiples relating to
Mobil to corresponding financial information, ratios and public market multiples
for the following six publicly traded companies:

        o   British Petroleum Company plc,

        o   Chevron Corporation,

        o   Exxon,

        o   Royal Dutch Petroleum Company,

        o   Shell Transport & Trading Co. plc, and

        o   Texaco Inc.

     The selected companies were chosen because they are publicly traded
companies that for purposes of analysis may be considered similar to Mobil.

     Goldman Sachs calculated and compared various financial multiples and
ratios. The multiples of Mobil were calculated using a price of $74.94 per
share, the closing price of Mobil common stock on November 24, 1998, the last
trading day prior to public reports that Mobil and Exxon were discussing a
potential business combination. The multiples and ratios for Mobil and for each
of the selected companies were based on the most recent publicly available
information.

</TABLE>

     The review also indicated that the dividend yield of the selected companies
ranged from 2.22% to 3.12%, compared to 3.04% for Mobil.

       5. Pro Forma Merger Analysis. Goldman Sachs prepared a pro forma analysis
of the financial impact of the merger. Using I/B/E/S International Inc. earnings
estimates for 1999 and 2000, Goldman Sachs compared the earnings per share of
Mobil common stock on a stand-alone basis and Exxon common stock on a
stand-alone basis, to the earnings per share of the common stock of the pro
forma combined company. Goldman Sachs performed this analysis based on the
exchange ratio of 1.32015 and under three scenarios reflecting cost savings and
operating synergies projected by the management of Mobil and Exxon to result
from the merger:

       o   Scenario I - assuming no synergies;

       o   Scenario II - assuming $950 million in pre-tax synergies are realized
           in 1999 and $1,820 million in pre-tax synergies are realized in 2000;
           and

       o   Scenario III - assuming $2,800 million in pre-tax synergies are
           realized in each of 1999 and 2000.

     This analysis indicated that:

        o  assuming Scenario I, the merger would be dilutive - that is, would
           represent a reduction - to both 1999 and 2000 earnings per share of
           Exxon common stock on a stand-alone basis and would be accretive-that
           is, would represent an addition - to 1999 and 2000 earnings per share
           of Mobil common stock on a stand-alone basis; and

        o  assuming Scenario II or Scenario III, the merger would be accretive
           in 1999 and 2000 to the earnings per share of Exxon common stock on a
           stand-alone basis and the earnings per share of Mobil common stock on
           a stand-alone basis.

       6. Selected Transactions Analysis. Goldman Sachs analyzed certain
information relating to the proposed transaction in relation to certain publicly
available information for 28 stock-for-stock transactions, substantially all of
which were in excess of $10 billion. Such analysis indicated that for the
selected transactions the premiums paid in such transactions as compared to:

        o  the target's price one day prior to the announcement of the
           transaction, ranged from a low of (5.8)% to a high of 58.8%, with a
           median of 12.1% and a mean of 17.0%, as compared to 15.1% for the
           proposed merger;

        o  the target's price one day prior to the date of any disclosure of the
           possible transaction (the "Disclosure Date"), ranged from a low of
           (5.2%) to a high of 70.5%, with a median of 20.7% and a mean of
           24.1%, as compared to 32.1% for the proposed transaction;

        o  the target's 30-day average price prior to the Disclosure Date,
           ranged from a low of (1.8)% to a high of 76.0%, with a median of
           18.6% and a mean of 28.1%, as compared to 33.6% for the proposed
           transaction;

                                      I-47


<PAGE>


Chapter One - The Merger


        o  the target's 90-day average price prior to the Disclosure Date,
           ranged from a low of (6.8)% to a high of 82.8%, with a median of
           21.9% and a mean of 28.7%, as compared to 31.5% for the proposed
           transaction; and

        o  the average of the daily exchange ratios for the 90-day period prior
           to the Disclosure Date, ranged from a low of (8.8)% to a high of
           53.6%, with a median of 16.9% and a mean of 18.6%, as compared to
           24.1% for the proposed transaction.

     The analysis further indicated that for the selected transactions, the
premium resulting from the target's share of the pro forma combined company
resulting from the transaction as compared with the target's market
capitalization relative to the combined market capitalization of the target and
the acquirer one day prior to the Disclosure Date ranged from a low of (4.4)% to
a high of 45.0%, with a median of 9.0% and a mean of 13.0%, as compared to 22.4%
for the proposed transaction.

     The preparation of a fairness opinion is a complex process and is not
necessarily susceptible to partial analysis or summary description. Selecting
portions of the analyses or of the summary set forth above, without considering
the analyses as a whole, could create an incomplete view of the processes
underlying Goldman Sachs' opinion. In arriving at its fairness determination,
Goldman Sachs considered the results of all such analyses. No company or
transaction used in the above analyses as a comparison is directly comparable to
Mobil or Exxon or the contemplated transaction.

     The analyses were prepared solely for purposes of Goldman Sachs' providing
its opinion to the Mobil Board as to the fairness from a financial point of view
of the exchange ratio to the holders, other than Exxon or any of its
subsidiaries or affiliates, of the outstanding shares of Mobil common stock and
do not purport to be appraisals or necessarily reflect the prices at which
businesses or securities actually may be sold. Analyses based upon forecasts of
future results are not necessarily indicative of actual future results, which
may be significantly more or less favorable than suggested by such analyses.
Because such analyses are inherently subject to uncertainty, being based upon
numerous factors or events beyond the control of the parties or their respective
advisors, none of Mobil, Exxon, Goldman Sachs nor any other person assumes
responsibility if future results are materially different from those forecast.

     As described above, Goldman Sachs' opinion to the Mobil Board was one of
many factors taken into consideration by the Mobil Board in making its
determination to approve the merger agreement. The foregoing summary does not
purport to be a complete description of the analysis performed by Goldman Sachs
in connection with such opinion and is qualified by reference to the written
opinion of Goldman Sachs set forth in Annex D.

     Goldman Sachs, as part of its investment banking business, is continually
engaged in the valuation of businesses and their securities in connection with
mergers and acquisitions, negotiated underwritings, competitive biddings,
secondary distributions of listed and unlisted securities, private placements
and valuations for estate, corporate and other purposes. Mobil selected Goldman
Sachs to render its opinion because it is a nationally recognized investment
banking firm that has substantial experience in transactions similar to the
merger. Goldman Sachs is familiar with Mobil having provided certain investment
banking services to Mobil from time to time, including having acted as dealer on
Mobil's commercial paper program; having acted as agent on Mobil's stock
repurchase program and medium term note program; and having acted as
lead-managing underwriter of a public offering of Mobil Corporation Pass Through
Certificates, Series 1997-A in May 1997. Goldman Sachs also has provided certain
investment banking services to Exxon from time to time, and may provide
investment banking services to Exxon in the future.

     Goldman Sachs provides a full range of financial advisory and securities
services and, in the course of its normal trading activities, may from time to
time effect transactions and hold securities, including derivative securities,
of Mobil or Exxon for its own account and for the accounts of customers.

                                                      Chapter One - The Merger


     Pursuant to a letter agreement dated November 22, 1998, Mobil engaged
Goldman Sachs to render its opinion in connection with the merger. Pursuant to
the terms of the Goldman Sachs engagement letter, Mobil has agreed to pay
Goldman Sachs a fee equal to (i) $100,000 per month beginning on November 30,
1998 and (ii) $8,000,000 payable upon the consummation of the merger or
acquisition of a majority of the common stock or assets of Mobil by Exxon, with
up to $2,400,000 of the fees paid pursuant to clause (i) above to be creditable
to any fees that become payable pursuant to clause (ii) above. From time to
time, Goldman Sachs has also provided other financial advisory services to
Mobil. Payment for certain of these services would be accelerated if the merger
is consummated. Mobil has also agreed to reimburse Goldman Sachs for its
reasonable out-of-pocket expenses, including attorney's fees, and to indemnify
Goldman Sachs against certain liabilities, including certain liabilities under
the federal securities laws. The SEC has taken the position that such
indemnification under the federal securities laws may not be enforceable if it
is found to be against public policy.


                   INTERESTS OF CERTAIN PERSONS IN THE MERGER

     In considering the recommendation of the Mobil Board with respect to the
merger agreement, shareholders should be aware that certain members of the
management of Mobil and the Mobil Board have interests in the merger that may be
different from, or in addition to, the interests of the other shareholders of
Mobil generally.

Board of Directors

     Exxon has agreed that, as of the closing, it will cause Mr. Noto and Mr.
Renna and four other persons who immediately prior to the closing were directors
but not employees of Mobil, to be elected to the Exxon Mobil Board. See "The
Merger Agreement--Exxon Mobil Board and Related Matters" on page I-55. It is
expected that Donald V. Fites, Charles A. Heimbold, Jr., Helene L. Kaplan and J.
Richard Munro will be the non-employee directors of Mobil who will be elected to
the Exxon Mobil Board as of the closing. For information about the benefits
received by Exxon directors, see "Chapter Four--Board of Directors Proposal:
Election of Directors--Director Compensation" on page IV-6.

Indemnification; Directors' and Officers' Insurance

     For seven years after the closing, Exxon has agreed to indemnify, to the
extent provided under Mobil's charter and by-laws in effect on December 1, 1998,
the individuals who on or before the closing were officers, directors and
employees of Mobil or its subsidiaries with respect to all acts or omissions
before the closing by these individuals in these capacities. Exxon has further
agreed to cause Mobil to honor all its indemnification agreements, including
under Mobil's by-laws, in effect on December 1, 1998. Exxon has also agreed to
provide, for seven years after the closing, directors' and officers' liability
insurance in respect of acts or omissions occurring before the closing covering
each person currently covered by Mobil's directors' and officers' liability
insurance policy. Exxon can discharge this obligation by providing an insurance
policy underwritten by a wholly-owned subsidiary of Exxon. See "The Merger
Agreement--Certain Covenants--Indemnification and Insurance of Mobil Directors
and Officers" on page I-57.

Employee Severance Plan

     On September 25, 1998, upon the recommendation of the Management
Compensation and Organization Committee of the Mobil Board (the "MCOC"), the
Mobil Board revoked Mobil's prior severance arrangements in the event of a
change in control of Mobil and adopted a cash-based employee severance plan.
Generally, all Mobil employees on the U.S. payroll who work a regular schedule
of at least 20 hours per week are eligible to participate in the severance plan.
However, temporary employees, employees represented by a collective bargaining
agent or subject to a collective bargaining agreement, leased employees,
employees of Mobil-owned and operated service stations and any person retained
pursuant to a written contract are not eligible to participate in the severance
plan.

Chapter One - The Merger


     Tier 1 employees comprising 19 senior executives, including Messrs. Noto,
Renna, Thomas C. DeLoach, Jr., Harold R. Cramer and Stephen D. Pryor and all
other executive officers of Mobil, as well as approximately 112 Tier 2
employees, approximately 1,329 Tier 3 employees and approximately 10,801 Tier 4
employees are eligible to receive severance benefits in the event of a
qualifying termination of their employment on or within two years following a
change in control, as such term is defined in the severance plan. In the
following discussion, we refer collectively to the employees listed in the
previous sentence as the covered employees and to Messrs. Noto, Renna, DeLoach,
Cramer and Pryor collectively as the Mobil named executive officers. A
qualifying termination of employment under the severance plan means (1) a
termination by the employer other than for "cause" (as defined in the severance
plan) or (2) a termination by the covered employee for "good reason" (as defined
in the severance plan). A termination by the covered employee for good reason
under the severance plan, in respect of a Tier 1, Tier 2 or Tier 3 employee
means:

        o  a reduction in the covered employee's base salary or incentive
           compensation opportunity in effect immediately prior to the change in
           control,

        o  the assignment to the covered employee of duties that in the
           aggregate are inconsistent with the covered employee's level of
           responsibility immediately before the change in control or any
           decline in the nature or status of the covered employee's
           responsibilities from those in effect immediately before the change
           in control and including, in the case of a Tier 1 or Tier 2 employee
           who was, immediately before the change in control, an executive
           officer, that employee ceasing to be an executive officer of a public
           company, or

        o  the relocation of the covered employee's principal place of
           employment to a location more than 50 miles from that employee's
           principal place of employment immediately before the change in
           control.

     A covered Tier 1, Tier 2 or Tier 3 employee who incurs a qualifying
termination of employment will be entitled to receive a cash lump sum severance
payment equal to:

        o  the sum of his or her annual base salary, plus the highest annual
           bonus received in the three years immediately before the change in
           control, plus the value of contributions or allocations made, as
           applicable, by Mobil on that employee's behalf to the employees
           savings plan of Mobil Oil Corporation and the supplemental savings
           benefit plan of Mobil Oil Corporation in the calendar year before the
           change in control,

       o   multiplied by 3 for Tier 1 employees, 2.5 for Tier 2 employees and
           2.0 for Tier 3 employees.

     A Tier 1, Tier 2 or Tier 3 employee who incurs a qualifying termination of
employment will also be provided with welfare benefits as if that employee had
continued to be employed by Mobil until the earlier to occur of:

        o  two years from the date of the qualifying termination of employment
           and

        o  that employee obtaining employment providing substantially similar
           welfare benefits.

     Under the severance plan, Mobil is required, if necessary, to make an
additional gross-up payment to any covered employee to offset fully the effect
of any excise tax imposed by Section 4999 of the Internal Revenue Code on any
excess parachute payment, whether made to that employee under the severance plan
or otherwise. In general, Section 4999 imposes an excise tax on the recipient of
any excess parachute payment equal to 20% of that payment. A parachute payment
is any payment that is contingent on a change in control. Excess parachute
payments consist of the excess of parachute payments over an individual's
average taxable compensation received by him from the employer during the five
taxable years preceding the year in which the change in control occurs. If the
individual has been employed for fewer than five taxable years, the individual's
entire period of employment will be used to calculate the excess parachute
payment.

<PAGE>


                                                      Chapter One - The Merger


     The merger will constitute a change in control under the severance plan. If
the closing had occurred on March 1, 1999 and if each of Messrs. Noto, Renna,
DeLoach, Cramer and Pryor had incurred a qualifying termination of employment
immediately following that date, the approximate amount of the cash severance
payment payable to each of the named executive officers would have been
$7,850,424 to Mr. Noto; $5,213,610 to Mr. Renna; $2,959,290 to Mr. DeLoach;
$2,352,000 to Mr. Cramer; and $2,342,190 to Mr. Pryor and the gross-up payment
payable would not be expected to exceed $5,712,767 to Mr. Noto; $3,413,624 to
Mr. Renna; $2,256,999 to Mr. DeLoach; $1,823,450 to Mr. Cramer; and $1,802,655
to Mr. Pryor.

Incentive Compensation and Stock Ownership Plans

     At the effective time, each outstanding option granted by Mobil to purchase
shares of Mobil common stock will be assumed by Exxon Mobil and will, after the
effective time, constitute an option to acquire, on the same terms and
conditions as applied to the Mobil stock option prior to the effective time, the
number, rounded down to the nearest whole number, of shares of Exxon Mobil
common stock determined by multiplying:

        o  the number of shares of Mobil common stock subject to the option
           immediately before the effective time by

        o  the exchange ratio.

The exercise price of each of these options will be a price per share of Exxon
Mobil common stock, rounded up to the nearest cent, equal to:

        o  the per share exercise price for Mobil common stock that otherwise
           could have been purchased under the Mobil stock option divided by

        o  the exchange ratio.

     Under the merger agreement, each other stock-based award granted by Mobil
under its employee or director plans or arrangements maintained as of December
1, 1998 will be converted, as of the effective time, into a similar Exxon Mobil
stock-based award, adjusted as appropriate to preserve the award's inherent
value.

     The other terms and conditions of these other stock-based awards, and the
plans or agreements under which they were issued, will continue to apply in
accordance with their terms and conditions as these terms and conditions have
been interpreted and applied by Mobil in accordance with its past practice.

     Upon a change in control, with respect to long-term conditional performance
shares previously granted to Mobil employees under Mobil's 1995 incentive
compensation and stock ownership plan and predecessor and successor plans, Exxon
Mobil will assume that all long-term incentive award performance factors have
been achieved at a 100% level. With respect to each employee and former employee
who has been granted performance shares relating to performance cycles in which
the change in control occurs, Exxon Mobil will calculate a prorated
number of the performance shares originally granted with respect to each
performance cycle. This number will be prorated for the number of months
completed in each performance cycle, to the date of the change in control. Exxon
Mobil will also calculate all notional dividends accrued to the date of the
change in control relating to all performance shares originally granted with
respect to each performance cycle. Similarly, Exxon Mobil will calculate any
notional dividends which are or may be accrued from the date of the change in
control relating to performance shares and notional dividends calculated as
provided above. Unless the employee, including a Mobil named executive officer,
before the end of the applicable performance cycle, is terminated for cause,
engages in willful misconduct, or voluntarily terminates his or her employment
to join a competitor, Exxon Mobil will pay the employee a cash amount in respect
of the performance shares and notional dividends calculated as provided above in
respect of the performance cycle at the same time and in the same manner as
would have been the case in the absence of a change in control. The merger will
constitute a change in control under the incentive plans.

                                      I-51


<PAGE>


Chapter One - The Merger


     In addition, upon a change in control, current and former Mobil employees,
including the Mobil named executive officers, who are eligible to receive annual
short-term incentive cash awards granted under incentive plans with respect to a
year in which a change in control occurs will receive an immediate payment of
that award for the year in which the change in control occurs, prorated for the
number of months completed in the year before the date of the change in control.
The award will be calculated by using the most current year information
available with respect to the attainment of applicable performance factors, or
where no current year information is available, using information from the full
preceding year.

     Since all long-term incentive award payments under the incentive plans will
be made on future dates, and because such payments will be based on the closing
prices of Exxon Mobil stock and the number of performance shares and notional
dividends in a participant's account on these future dates, it is impossible to
calculate what payments, if any, an employee, including a Mobil named executive
officer, with one or more outstanding conditional long-term incentive awards may
become entitled to receive.

     If the closing had occurred on March 1, 1999, each Mobil named executive
officer would have become entitled to a payment upon the closing of the merger
of a short-term incentive cash award for 1998, estimated to equal the following
amounts: $256,283 to Mr. Noto; $145,750 to Mr. Renna; $70,417 to Mr. DeLoach;
$56,250 to Mr. Cramer; and $56,250 to Mr. Pryor.

Management Retention Plan

     The management retention plan provides for conditional retention awards to
selected executives of Mobil, including all of the Mobil named executive
officers and eight other executive officers. Generally, payment under the
management retention plan is only made after normal retirement, an approved
early retirement, or the death or disability of a participant, provided that the
participant's performance was at a level satisfactory to Mobil over the period
the award remained conditional. Before the merger, the MCOC determined that all
current management retention plan participants had rendered long-term service to
Mobil at a level satisfactory to Mobil. In the merger agreement, Exxon
acknowledged that the MCOC had determined that all participants covered by the
management retention plan had performed at a level satisfactory to Mobil over
the period that the conditional retention awards were outstanding and,
accordingly, that all participants would be entitled to full payment under the
management retention plan were they to retire or otherwise terminate their
employment with Mobil. Exxon agreed to give considerable weight to such
determination in administering the management retention plan after the merger,
given the significant length of time that has elapsed since the award grants.

     If the closing had occurred on March 1, 1999, and if the employment of each
Mobil named executive officer had terminated immediately following that time,
the amount payable under the management retention plan in respect of retention
awards, based upon the per share closing price of Mobil stock on March 1, 1999
of $81 would have been $2,185,704 to Mr. Noto; $1,985,553 to Mr. Renna;
$1,385,019 to Mr. DeLoach; $923,238 to Mr. Cramer; and $461,538 to Mr. Pryor.

Rabbi Trust

     Mobil maintains an irrevocable "rabbi trust" which secures Mobil's
obligations under certain employee benefit and executive compensation programs,
including the management retention plan and the obligations under the severance
plan relating to employees, including all executive officers, in salary group 20
or higher. As of December 31, 1998, the rabbi trust held assets valued at
approximately $692,951,000. The rabbi trust will continue to hold assets
following the merger.

Application of Past Practices

     Exxon has agreed that the incentive plans, the management retention plan,
the supplemental pension annuity program of Mobil Oil Corporation, the executive
life insurance program of Mobil Oil Corporation and the severance plan, as well
as any award made under any of these executive arrangements, will be
administered in accordance with the past practices and interpretations of the
Mobil Board and the MCOC with respect to eligibility,

vesting, term and payment, among other matters.  Any question regarding the
past practices and interpretations of the Mobil Board and the MCOC and the
application of these past practices and interpretations to the type of
facts and circumstances in a given case will be referred to Mr. Noto or
his designee for a final decision.  This decision shall not be inconsistent
with the intention of the merger agreement and the merger.

Chapter One - The Merger

                              THE MERGER AGREEMENT

     The following summary of the merger agreement is qualified by reference to
the complete text of the merger agreement, which is incorporated by reference
and attached as Annex A.

Structure of the Merger

     Under the merger agreement, an Exxon subsidiary will merge into Mobil so
that Mobil becomes a wholly-owned subsidiary of Exxon Mobil.

Timing of Closing

     The closing will occur within three business days after the day on which
the last of the conditions set forth in the merger agreement has been satisfied
or waived, unless Exxon and Mobil agree to a different date. We expect that,
immediately upon the closing of the merger, we will file a merger certificate
with the Secretary of State of the State of Delaware, at which time the merger
will be effective.

Merger Consideration

     The merger agreement provides that each share of Mobil common stock
outstanding immediately prior to the effective time will, at the effective time,
be converted into the right to receive 1.32015 shares of Exxon Mobil common
stock. However, any shares of Mobil common stock held by Mobil as treasury stock
or owned by Exxon or any subsidiary of Exxon will be canceled without any
payment for those shares. Shares held in Mobil's rabbi trust will not be treated
as treasury stock for this purpose.

     In addition, each outstanding share of Mobil ESOP preferred stock held in
the leveraged ESOP portion of the Employees Savings Plan of Mobil Oil
Corporation will, at the effective time, be converted into the right to receive
one share of a new series of Exxon preferred stock (the "Exxon Mobil ESOP
preferred stock") having, to the extent possible, terms identical to those of
the Mobil ESOP preferred stock.

Treatment of Mobil Stock Options; Other Mobil Stock-Based Awards

     At the effective time, each outstanding option granted by Mobil to purchase
shares of Mobil common stock will be converted into an option to acquire Exxon
Mobil common stock having the same terms and conditions as the Mobil stock
option had before the effective time. The number of shares that the new Exxon
Mobil option will be exercisable for and the exercise price of the new Exxon
Mobil option will reflect the exchange ratio in the merger.

     Each other stock-based award granted by Mobil under its employee or
director plans or arrangements maintained as of December 1, 1998 will be
converted, as of the effective time, into a similar Exxon Mobil stock-based
award, adjusted as appropriate to preserve the award's inherent value. For
additional information on Mobil stock-based awards, see "Interests of Certain
Persons in the Merger" on page I-49.

Exchange of Shares

     We will appoint an exchange agent to handle the exchange of Mobil stock
certificates in the merger for Exxon Mobil stock and the payment of cash for
fractional shares of Mobil stock. Soon after the closing, the exchange agent
will send to each holder of Mobil stock a letter of transmittal for use in the
exchange and instructions explaining how to surrender Mobil stock certificates
to the exchange agent. Holders of Mobil stock that surrender their certificates
to the exchange agent, together with a properly completed letter of transmittal,
will receive the appropriate merger consideration. Holders of unexchanged shares
of Mobil stock will not be entitled to receive any dividends or other
distributions payable by Exxon Mobil after the closing until their certificates
are surrendered.

                                      I-54


<PAGE>


                                                      Chapter One - The Merger


     Exxon Mobil will not issue any fractional shares in the merger. Holders of
Mobil common stock will receive a cash payment in the amount of the proceeds
from the sale of their fractional shares in the market.

Exxon Mobil Board and Related Matters

     Exxon has agreed to take the necessary corporate action so that, as of the
closing:

        o  The Exxon Mobil Board size will be increased from 13 to 19.

        o  Two employee directors of Mobil will become directors of Exxon Mobil.
           They are expected to be Lucio A. Noto and Eugene A. Renna.

        o  Four non-employee directors of Mobil will become directors of Exxon
           Mobil.  They are expected to be Donald V. Fites, Charles A. Heimbold,
           Jr., Helene L. Kaplan and J. Richard Munro.

        o  Mr. Noto will become Vice-Chairman of the Exxon Mobil Board.

        o  At least one Mobil designee will become a member of each of the Exxon
           Mobil Audit Committee and the Exxon Mobil Compensation Committee.

     If the closing is within nine months of the next regularly scheduled
annual meeting of shareholders of Exxon Mobil, Exxon has agreed, in each
case as of such next annual meeting, * to nominate the Mobil designees to
the Exxon Mobil Board, * to elect Mr. Noto as Vice Chairman, and * to
have at least one Mobil designee on each of the Compensation Committee and
Audit Committee of Exxon Mobil.

Certain Covenants

     Each of Exxon and Mobil has undertaken certain covenants in the merger
agreement. The following summarizes the more significant of these covenants.

     No Solicitation by Mobil. Mobil has agreed that it and its subsidiaries and
their officers, directors, employees and advisers will not take action to
solicit or encourage an offer for an alternative acquisition transaction
involving Mobil of a nature defined in the merger agreement.

     Restricted actions include engaging in discussions or negotiations with any
potential bidder, or disclosing non-public information relating to Mobil or its
subsidiaries or affording access to their properties, books or records to a
potential bidder.  These actions are permitted in response to an
unsolicited bona fide offer so long as prior to doing so: * the Mobil
Board by a majority vote determines in its good faith judgment that it is
necessary to do so to comply with its fiduciary duty to shareholders, after
receiving the advice of outside legal counsel, and * Mobil receives from
such person an executed confidentiality agreement with terms no less
favorable to Mobil than those contained in the existing confidentiality
agreement between Exxon and Mobil.

     Mobil must keep Exxon informed of the identity of any potential bidder and
the terms and status of any offer. If its Board reaches the fiduciary duty
determination described in the previous paragraph that it is necessary to do so,
Mobil can withhold that information.

     Mobil Board's Covenant to Recommend. The Mobil Board has agreed to
recommend the approval and adoption of the merger agreement to Mobil's
shareholders.  However, the Mobil Board is permitted not to make, to
withdraw or to modify in a manner adverse to Exxon this recommendation if
* the Mobil Board by a majority vote determines in its good faith
judgment that it is necessary to do so to comply with its fiduciary duty to
shareholders under applicable law, after receiving the advice of outside
legal counsel, and * Mobil and the senior officers and directors of Mobil
have substantially complied with their obligations under the no-
solicitation covenant described above under "--No Solicitation by Mobil."

Chapter One - The Merger


     Exxon Board's Covenant to Recommend. The Exxon Board has agreed to
recommend the approval of the Exxon Merger Proposals to Exxon's shareholders.
However, the Exxon Board is permitted not to make, to withdraw or to modify in a
manner adverse to Mobil this recommendation if the Exxon Board by a majority
vote determines in its good faith judgment that it is necessary to do so to
comply with its fiduciary duty to shareholders under applicable law, after
receiving the advice of outside legal counsel.

     Interim Operations of Exxon and Mobil. Each of Exxon and Mobil has
undertaken a separate covenant that places restrictions on it and its
subsidiaries until either the effective time or the merger agreement is
terminated. In general, Exxon and its subsidiaries and Mobil and its
subsidiaries are required to conduct their business in the ordinary course
consistent with past practice and to use their reasonable best efforts to
preserve intact their business organizations and relationships with third
parties. The companies have also agreed to some specific restrictions which are
subject to exceptions described in the merger agreement. The following table
summarizes the more significant of these restrictions undertaken by each
company:

     Best Efforts Covenant. Exxon and Mobil have agreed to cooperate with each
other and use their best efforts to take all actions and do all things necessary
or advisable under the merger agreement and applicable laws to complete the
merger and the other transactions contemplated by the merger agreement. However,
neither Exxon

                                                      Chapter One - The Merger


nor Mobil is required to take any action if the result would give Exxon the
right to decline to close the merger because such action could reasonably
be expected to result in a substantial detriment to Exxon, Mobil and their
subsidiaries, taken as a whole.

     Certain Employee Benefits Matters. The merger agreement provides that Exxon
Mobil will cause Mobil to honor in accordance with their terms all obligations
under Mobil's executive benefit arrangements and under all other existing Mobil
employee and retiree arrangements and plans to the extent entitlements or rights
exist under those arrangements or plans as of the closing.

     Exxon has also agreed, following the closing, to provide Mobil employees
who were employed by Mobil or its subsidiaries at the closing and who continue
as employees of Exxon Mobil or its subsidiaries, for so long as they remain so
employed, employee benefits, other than salary or incentive compensation,
* pursuant to benefit plans and arrangements as provided to those employees
immediately prior to the closing, or * pursuant to benefit plans and
arrangements maintained by Exxon Mobil providing coverage and benefits
which, in the aggregate, are no less favorable than those provided to
employees of Exxon Mobil in positions comparable to the positions held by
the continuing Mobil employees.

     In addition, Exxon has agreed that, following the closing, Exxon Mobil
will continue to provide former employees of Mobil and its subsidiaries
(and to Mobil employees whose employment terminates prior to the closing)
post retirement benefits, other than pensions, * pursuant to benefit
plans and arrangements applicable to those retirees as in effect as of
December 1, 1998, or * pursuant to benefit plans or arrangements
maintained by Exxon Mobil or its subsidiaries providing post-retirement
coverage and benefits, other than pensions, which, in the aggregate, are no
less favorable than those provided to former employees of Exxon.

     Please see "Interests of Certain Persons in the Merger," beginning on page
I-49, for additional information on employee benefits matters covered in the
merger agreement.

     Indemnification and Insurance of Mobil Directors and Officers.  Exxon has
agreed that:

        o  For seven years after closing, it will indemnify former Mobil
           directors, officers and employees for liabilities from their acts or
           omissions in those capacities occurring prior to closing to the
           extent provided under Mobil's charter and by-laws as in effect on
           December 1, 1998.

        o  It will cause Mobil to honor all indemnification agreements with its
           former directors, officers and employees in effect as of December 1,
           1998.

        o  For seven years after closing, it will provide officers' and
           directors' liability insurance covering acts or omissions occurring
           prior to closing by each person currently covered by Mobil's
           officers' and directors' liability insurance policy. This Exxon Mobil
           policy must be no less favorable than the Mobil policy in effect on
           December 1, 1998, except that Exxon Mobil will only be obligated to
           pay up to 300% of the annual premium paid by Mobil for such insurance
           as of December 1, 1998. Exxon may provide this coverage through a
           policy underwritten by a wholly-owned Exxon subsidiary.

     Certain Other Covenants.  The merger agreement contains mutual covenants of
the parties, the most significant of which are that each party agrees:

        o  not to jeopardize the intended tax or accounting treatment of the
           merger, and

        o  to establish a transition committee to plan the integration of Exxon
           and Mobil after the closing.

matters, including the inapplicability of the Delaware anti-takeover statute and
Mobil's shareholder rights plan to the merger and the Mobil stock option. For
information about the anti-takeover statute and the rights plan, see "Chapter
Three--Certain Legal Information--Comparison of Shareholder Rights--Shareholder
Rights Plan" and "Certain Business Combinations" on pages III-4 and III-6.

     The representations and warranties in the merger agreement do not survive
the closing or termination of the merger agreement.

        o  approval by the European Commission of the contemplated transactions

        o  absence of legal prohibition on completion of the merger

        o  Exxon's registration statement on Form S-4, which includes this proxy

        o  receipt of opinions of Exxon's and Mobil's counsel that the merger
           will qualify as a tax-free reorganization

        o  absence of a material adverse effect or any reasonable expectation of

        o  accuracy as of closing of the representations and warranties made by
           the other party to the extent specified in the merger agreement

        o  performance in all material respects by the other party of the
           obligations required to be performed by it at or prior to closing

     Additional Closing Conditions for Exxon's Benefit.  Exxon's obligation to
complete the merger is subject to the following additional conditions:

        o  there being no proceeding seeking to limit Exxon's ownership of Mobil
           or to compel divestiture of assets, in either case to an extent that
           could reasonably be expected to result in a substantial detriment to
           Exxon and Mobil taken as a whole

        o  all regulatory approvals for the merger being obtained on terms that
           are not reasonably likely to result in such a substantial detriment

Termination of the Merger Agreement

     Right to Terminate.  The merger agreement may be terminated at any time
prior to the closing in any of the following ways:

      (a) The merger agreement may be terminated by mutual written consent of
   Exxon and Mobil.

      (b) The merger agreement may be terminated by either Exxon or Mobil if:

                    o    the merger has not been completed by December 1, 1999.
                         However, that date becomes June 30, 2000 if the reason
                         for not closing by December 1, 1999 is that the
                         regulatory conditions specified in the merger agreement
                         have not been satisfied by that date,

                    o    Exxon or Mobil shareholders fail to give the necessary
                         approval at a duly held meeting, or

                    o    there is a permanent legal prohibition to closing the
                         merger.

      (c) The merger agreement may be terminated by Exxon if the Mobil Board
   fails to recommend the merger or withdraws or modifies in a manner adverse
   to Exxon its approval or recommendation of the merger, breaches its
   agreement to call the Mobil meeting or recommends a superior offer.

      (d) The merger agreement may be terminated by Mobil if:

                    o    the Mobil Board authorizes Mobil, subject to complying
                         with the merger agreement, to enter into a binding
                         written agreement concerning an acquisition proposal
                         for at least a majority of the Mobil stock on terms the
                         Mobil Board determines, in good faith after
                         consultation with its financial advisors, are more
                         favorable to Mobil shareholders than the merger, and
                         Mobil notifies Exxon in writing that it intends to
                         enter into such an agreement, attaching the most
                         current version of the agreement or a description of
                         all its material terms and conditions,

                    o    Exxon does not make an offer, within three business
                         days after receiving the notice, that the Mobil Board
                         determines, in good faith after consultation

                         with its financial advisors, is at least as
                         favorable to the Mobil shareholders as the
                         superior proposal, and

                    o    Mobil has paid Exxon the cash termination fee described
                         under "--Termination Fees Payable by Mobil" below.

      (e) The merger agreement may be terminated by Mobil if the Exxon Board
   fails to recommend the merger or withdraws or modifies in a manner adverse
   to Mobil its approval or recommendation of the merger or breaches its
   agreement to call the Exxon meeting.

     Neither Exxon nor Mobil can terminate the merger agreement for the reasons
described in the first bullet under paragraph (b) above if its failure to
fulfill in any material respect its obligations under the merger agreement has
resulted in the failure to complete the merger.

     If the merger agreement is validly terminated, the agreement will become
void without any liability on the part of any party unless such party is in
willful breach thereof. However, the provisions of the merger agreement relating
to expenses and termination fees, as well as the confidentiality agreement and
the stock option agreement entered into between Exxon and Mobil, will continue
in effect notwithstanding termination of the merger agreement.

     Termination Fees Payable by Mobil.  Mobil has agreed to pay Exxon a cash
amount equal to $1.5 billion in any of the following circumstances:

        o  Mobil terminates the merger agreement as described in paragraph (d)
           under "--Right to Terminate" above

        o  Exxon terminates the merger agreement as described in paragraph (c)
           under "--Right to Terminate" above, unless at the relevant time Exxon
           is in material breach in the manner described in the merger agreement

        o  either Exxon or Mobil terminates the merger agreement in
           circumstances where the following three conditions are met:

           o  Mobil's shareholders do not vote in favor of the merger,

           o  a third party has made a proposal for an alternative transaction,
              and

           o  within twelve months of the termination of the merger agreement
              Mobil enters into an agreement for an alternative transaction with
              that third party, or with another third party at a value per Mobil
              share higher than $95.96.

     Termination Fees Payable by Exxon. Exxon has agreed to pay Mobil a cash
amount equal to $1.5 billion if Mobil terminates the merger agreement as
described in paragraph (e) under "--Right to Terminate" above, unless at the
relevant time Mobil is in material breach in the manner described in the merger
agreement.

Other Expenses

     Except as described above and subject to an exception relating to the
payment of transfer taxes, all costs and expenses incurred in connection with
the merger agreement and related transactions will be paid by the party
incurring such costs or expenses. We estimate that merger-related fees and
expenses, consisting primarily of SEC filing fees, fees and expenses of
investment bankers, attorneys and accountants, and financial printing and
other related charges, will total approximately $90 million assuming the
merger is completed.

Amendments; Waivers

     Any provision of the merger agreement may be amended or waived prior to
closing if the amendment or waiver is in writing and signed, in the case of an
amendment, by Mobil, Exxon and the merger subsidiary or, in the case of a
waiver, by the party against whom the waiver is to be effective. After the
approval of the merger agreement by the shareholders of Mobil, no amendment or
waiver that by law requires further approval by shareholders may be made without
the further approval of such shareholders.

Stock Option Agreement

     The following summary of the stock option agreement is qualified by
reference to the complete text of the agreement, which is incorporated by
reference and attached as Annex B.

     General. At the same time that Exxon and Mobil entered into the merger
agreement, they also entered into a stock option agreement. Under the stock
option agreement, Mobil granted Exxon an irrevocable option to purchase up to
136.5 million shares of Mobil common stock at a price per share of $95.96. The
option is exercisable in the circumstances described below.

     Exercise of the Stock Option. Exxon can exercise the option in whole or in
part at any time after the occurrence of any event, which we call a trigger
event in this section, entitling Exxon to receive the cash termination fee
payable by Mobil pursuant to the merger agreement (see "--Termination of the
Merger Agreement--Termination Fees Payable by Mobil") and prior to termination
of the option.

     The option terminates upon the earliest to occur of

      (1)  the closing of the merger,

      (2)  90 days after Mobil has paid the cash termination fee in full, or

      (3)  one day after termination of the merger agreement so long as, in the
     case of this clause (3), no trigger event has occurred or could still
     occur.

     If a third party makes an offer to acquire Mobil at a value per share of
Mobil common stock which is lower than the $95.96 exercise price specified
above, the exercise price with respect to 1,000 option shares will be adjusted
to be 90% of the per share value offered by the third party. The exercise price
and number of option shares are also subject to certain anti-dilution and other
adjustments specified in the stock option agreement.

     Any purchase of option shares is subject to specified closing conditions,
including receipt of applicable regulatory approvals. The closing of any
purchase of option shares may be postponed for up to nine months beyond the
termination of the option pending satisfaction of the conditions to purchase.

     Cash Election. The stock option agreement further provides that, so long as
the option is exercisable, Exxon may, instead of exercising the option, elect to
require Mobil to pay to Exxon in exchange for the cancellation of the relevant
portion of the option an amount in cash equal to the "spread" (as defined below)
multiplied by the number of option shares as to which this cash election is
made.

     "Spread" means the excess, if any, over the exercise price of the higher of
(1) the highest price per share of Mobil common stock paid or proposed to be
paid by any third party pursuant to an alternative acquisition proposal and (2)
the average of the closing price of the Mobil common stock on the NYSE at the
end of its regular session, as reported on the Consolidated Tape, for the
five consecutive trading days ending on and including the date immediately
preceding the date on which Exxon notifies Mobil of this cash election.

                                      I-61


<PAGE>


Chapter One - The Merger


     Listing and Registration Rights. Mobil has agreed to list the option shares
on the NYSE and to grant Exxon customary rights to require registration by Mobil
of option shares for sale by Exxon under the securities laws.

     Limitation on Total Profit. The stock option agreement provides that,
notwithstanding any other provision of that agreement or the merger agreement,
Exxon's Total Profit (as defined below) will not exceed $2 billion in the
aggregate. If Exxon's Total Profit otherwise would exceed such amount, Exxon, at
its sole election, may (a) pay cash to Mobil, (b) deliver to Mobil for
cancellation Option Shares previously acquired by Exxon or (c) any combination
thereof, so that Exxon's actually realized Total Profit does not exceed $2
billion after taking into account the foregoing actions.

     For purposes of the stock option agreement, "Total Profit" means the
aggregate amount, before taxes, of the following: (1) (x) the cash amount
actually received by Exxon in payment by Mobil of the termination fee under the
merger agreement, less (y) any repayment by Exxon as described in the preceding
paragraph; (2) the net cash amounts received by Exxon pursuant to the sale of
option shares (or of any other securities into or for which such option shares
are converted or exchanged), less Exxon's purchase price for such option shares
(or other securities), plus (3) the aggregate amount received by Exxon pursuant
to exercise of the cash election described under "--Cash Election" above.

     The stock option agreement also provides that, notwithstanding any other
provision of the agreement, the option may not be exercised for a number of
option shares that would, as of the date of exercise, result in a Notional Total
Profit (as described below) exceeding $2 billion. For purposes of the stock
option agreement, the "Notional Total Profit" with respect to the option shares
for which Exxon may propose to exercise the option means the Total Profit
determined as of the date Exxon notifies Mobil of its intent to exercise the
option and assuming that the applicable option shares, together with all other
option shares previously acquired upon exercise of the option and held by Exxon
or its affiliates as of such date, were sold for cash at the NYSE closing price
on the preceding trading day.

     Effect of Option. The option is intended to make it more likely that the
merger will be completed on the agreed terms and to compensate Exxon for its
efforts and costs in case the merger is not completed under circumstances
generally involving a third party proposal for a business combination with
Mobil. Among other effects, the option could prevent an alternative business
combination with Mobil from being accounted for as a "pooling of interests". The
option may therefore discourage proposals for alternative business combinations
with Mobil, even if a third party were prepared to offer Mobil shareholders
consideration with a higher market value than the value of the Exxon Mobil stock
to be exchanged for Mobil stock in the merger.

     Proxies for Participants in Exxon Plans. You may receive more than one
proxy or voting card depending on how you hold your shares. Shares registered in
your name and shares held in your Shareholder Investment Program (SIP) account
are covered by one card. Exxon employees receive a separate card for any shares
they hold in Exxon's Thrift Plan.

     Proxies for Participants in Mobil Plans. If you are a participant in
Mobil's Stock Purchase and Dividend Reinvestment Plan, Employees Savings Plan
and/or Employee Stock Ownership Plan, you will receive a single proxy card which
covers shares credited to your plan accounts plus shares held of record in the
same name. If your account in any such plan is not carried in the same name as
the shares, if any, you hold of record, you will receive separate proxy cards
for your individual and plan holdings. If you are a participant in Mobil's
Employees Savings Plan and you do not vote the shares credited to your plan
account, such shares will be voted by the plan's trustee FOR approval and
adoption of the merger agreement, FOR the election of the nominees for director,
FOR the ratification of the appointment of Mobil's independent auditors and
AGAINST the three proposals submitted by shareholders of Mobil. If you are a
participant in Mobil's Employee Stock Ownership Plan and you do not vote the
shares credited to your plan account, such shares will be voted by the plan's
trustee in the same proportion that the trustee votes all the shares allocated
to the accounts of regular Mobil employees as to which it has received timely
voting instructions.

     Voting in person. If you plan to attend a meeting and wish to vote in
person, we will give you a ballot at the meeting. However, if your shares are
held in the name of your broker, bank or other nominee, you must bring an
account statement or letter from the nominee indicating that you are the
beneficial owner of the shares on March 29, 1999, the record date for voting.

     People with disabilities. We can provide reasonable assistance to help you
participate in the meeting if you tell us about your disability and your plan to

     Proxy solicitation.  We will pay our own costs of soliciting proxies.

     In addition to this mailing, Exxon and Mobil employees may solicit proxies
personally, electronically or by telephone. Exxon is paying D. F. King & Co. a
fee of $25,000 plus expenses to help with the solicitation. Mobil is paying

                       Chapter Two - Information about the Meetings and Voting


     The extent to which these proxy soliciting efforts will be necessary
depends entirely upon how promptly proxies are submitted. You should send in
your proxy by mail, telephone or internet without delay. We also reimburse
brokers and other nominees for their expenses in sending these materials to you
and getting your voting instructions.

     Do not send in any stock certificates with your proxy cards. The exchange
agent will mail transmittal forms with instructions for the surrender of stock
certificates for Mobil common stock and Mobil ESOP preferred stock to former
Mobil shareholders as soon as practicable after the completion of the merger.

Other Business; Adjournments

     We are not currently aware of any other business to be acted upon at either
meeting. Under the laws of New Jersey, where Exxon is incorporated, no business
other than procedural matters may be raised at the Exxon meeting unless proper
notice to the shareholders has been given. If, however, other matters are
properly brought before either meeting, or any adjourned meeting, your proxies
will have discretion to vote or act on those matters according to their best
judgment, including to adjourn the meeting.

     Adjournments may be made for the purpose of, among other things, soliciting
additional proxies. Any adjournment may be made from time to time by approval of
the holders of shares representing a majority of the votes present in person or
by proxy at the meeting, whether or not a quorum exists, without further notice
other than by an announcement made at the meeting. Neither of us currently
intends to seek an adjournment of our meeting.

                    DESCRIPTION OF EXXON CAPITAL STOCK

               The following summary of the current terms of the capital stock
of Exxon and the terms of the capital stock of Exxon Mobil to be in effect
after completion of the merger is not meant to be complete and is qualified by
reference to the Exxon charter and Exxon by-laws.  Copies of the Exxon charter
and Exxon by-laws are incorporated by reference and will be sent to holders of
shares of Exxon common stock, Exxon Class A preferred stock, Mobil common
stock and Mobil ESOP preferred stock upon request.  See "Where You Can Find
More Information" on page VI-1.

Authorized Capital Stock

               Prior to Completion of the Merger.  Under the Exxon charter,
Exxon's authorized capital stock consists of three billion shares of Exxon
common stock, without par value, and 200 million shares of preferred stock,
without par value, of which 16.5 million shares are designated as Exxon Class
A preferred stock and 100 million are designated as Exxon Class B preferred
stock, each without par value.

               Following Completion of the Merger.  If the merger is
completed, the Exxon Mobil charter will be amended to increase the authorized
number of shares of Exxon Mobil common stock to 4.5 billion and to eliminate
the Exxon Class B preferred stock, none of which is outstanding.  See
"Amendment of Exxon Charter" beginning on page III-10.  In connection with the
merger, the Exxon Board has agreed to create the Exxon Mobil ESOP preferred
stock.  The Exxon Mobil ESOP preferred stock will have, to the extent
possible, terms that are identical to those of the Mobil ESOP preferred stock.

Exxon Common Stock

               Exxon Common Stock Outstanding.  The outstanding shares of
Exxon common stock are, and the shares of Exxon Mobil common stock issued
pursuant to the merger will be, duly authorized, validly issued, fully paid and
nonassessable.

               Voting Rights.  Each holder of Exxon common stock is entitled
to one vote for each share of Exxon common stock held of record on the
applicable record date on all matters submitted to a vote of shareholders.
See page II-2 for additional information on Exxon voting rights.

               Dividend Rights; Rights upon Liquidation.  The holders of Exxon
common stock are entitled to receive, from funds legally available for the
payment thereof, dividends when and as declared by resolution of the Exxon
Board, subject to any preferential dividend rights granted to the holders of
any outstanding Exxon preferred stock.  In the event of liquidation, each
share of Exxon common stock is entitled to share pro rata in any distribution
of Exxon's assets after payment or providing for the payment of liabilities
and the liquidation preference of any outstanding Exxon preferred stock.

               Preemptive Rights.  Holders of Exxon common stock have no
preemptive rights to purchase, subscribe for or otherwise acquire any unissued
or treasury shares or other securities.

Exxon Preferred Stock

               Exxon Preferred Stock Outstanding.  As of March 1, 1999, (1)
1,593,644 shares of Exxon Class A preferred stock were issued and outstanding
and (2) no other shares of preferred stock were issued or outstanding.

               As of March 1, 1999, approximately 163,383 shares of Mobil ESOP
preferred stock were issued and outstanding.

               Blank Check Preferred Stock.  Under the Exxon charter, the
Exxon Board has the authority, without shareholder approval, to create one or
more classes or series within a class of preferred stock, to issue shares of

                                   III-8
<PAGE>

                                     Chapter Three - Certain Legal Information

preferred stock in such class or series up to the maximum number of shares of
the relevant class or series of preferred stock authorized, and to determine
the preferences, rights, privileges and restrictions of any such class or
series, including the dividend rights, voting rights, the rights and terms of
redemption, the rights and terms of conversion, liquidation preferences, the
number of shares constituting any such class or series and the designation of
such class or series.  Acting under this authority, the Exxon Board could
create and issue a class or series of preferred stock with rights, privileges
or restrictions, and adopt a shareholder rights plan, having the effect of
discriminating against an existing or prospective holder of securities as a
result of such shareholder beneficially owning or commencing a tender offer
for a substantial amount of Exxon common stock.  One of the effects of
authorized but unissued and unreserved shares of capital stock may be to
render more difficult or discourage an attempt by a potential acquiror to
obtain control of Exxon by means of a merger, tender offer, proxy contest or
otherwise, and thereby protect the continuity of Exxon's management.  The
issuance of such shares of capital stock may have the effect of delaying,
deferring or preventing a change in control of Exxon without any further
action by the shareholders of Exxon.  Exxon has no present intention to adopt
a shareholder rights plan, but could do so without shareholder approval at any
future time.

               Voting Rights of Exxon Class A Preferred Stock and Exxon Mobil
ESOP Preferred Stock.  Each holder of Exxon Class A preferred stock is
entitled to vote on all matters submitted to a vote of Exxon common stock,
voting together with the Exxon common stock as a single class.  Each share of
Exxon Class A preferred stock is entitled to the number of votes equal to the
number of shares of Exxon common stock into which such share of Exxon Class
A preferred stock could be converted on the record date for the applicable
meeting, subject to adjustment in the case of certain dilutive events.

               Upon completion of the merger, holders of Exxon Mobil ESOP
preferred stock will be entitled to vote on all matters submitted to a vote of
holders of Exxon Mobil common stock, voting together with the Exxon Mobil
common stock and the Exxon Class A preferred stock, as a single class.  Each
share of Exxon Mobil ESOP preferred stock will be entitled to the number of
votes equal to the number of shares of Exxon Mobil common stock into which
such share of Exxon Mobil ESOP preferred stock could be converted on the
record date for the applicable meeting, subject to adjustment in the case of
certain dilutive events.

               Dividend Rights and Rights Upon Liquidation of Exxon Class A
Preferred Stock and Exxon Mobil ESOP Preferred Stock.  The holders of Exxon
Class A preferred stock are entitled to receive, from funds legally available
for the payment thereof, dividends when and as declared by resolution of the
Exxon Board at a per share rate of $4.68 per annum, subject to adjustment in
the case of certain dilutive events.  In the event of liquidation or
dissolution, after payment or providing for the payment of liabilities and the
liquidation preference of any class of stock ranking senior to the Exxon Class
A preferred stock, each share of Exxon Class A preferred stock will be
entitled to receive $61.50 per share of Exxon Class A preferred stock, subject
to adjustment, plus accrued and unpaid dividends.

               Upon completion of the merger, holders of Exxon Mobil ESOP
preferred stock will be entitled to dividends and liquidation preference on
terms that, to the extent possible, are identical to the terms of the Mobil
ESOP preferred stock.  Holders of Mobil ESOP preferred stock are entitled to
receive, from funds legally available for the payment thereof, dividends when
and as declared by resolution of the Mobil Board at a per share rate of $300
per annum, subject to adjustment in the case of certain dilutive events.  In
the event of liquidation or dissolution, after payment or providing for the
payment of liabilities and the liquidation preference of any class of stock
ranking senior to the Mobil ESOP preferred stock, each share of Mobil ESOP
preferred stock is entitled to receive $3,887.50 per share of Mobil ESOP
preferred stock, subject to adjustment, plus accrued and unpaid dividends.

               Redemption Rights.  Shares of Exxon Class A preferred stock are
redeemable at the option of Exxon at any time for $61.50 plus accrued and
unpaid dividends.  Shares of Exxon Mobil ESOP preferred stock will be
redeemable at the option of Exxon Mobil at any time after November 22, 1999 at
the liquidation price plus accrued and unpaid dividends.  These shares are
redeemable before November 22, 1999 for 100.775% of the liquidation price plus
accrued and unpaid dividends.

Chapter Three - Certain Legal Information

               Preemptive Rights.  Holders of Exxon Class A preferred stock
have no preemptive rights to purchase, subscribe for or otherwise acquire any
unissued or treasury shares or other securities.

               Upon completion of the merger, the holders of Exxon Mobil ESOP
preferred stock will have no preemptive rights to purchase, subscribe for or
otherwise acquire any unissued or treasury shares or other securities.

Amendment of Exxon Charter (Item 2 on Exxon's proxy card)

               At the Exxon meeting, holders of Exxon stock will be asked to
approve the amendment of Exxon's Restated Certificate of Incorporation.  The
amendment will increase the number of authorized shares of Exxon common stock
to 4.5 billion, change Exxon's name to "Exxon Mobil Corporation" and eliminate
Exxon's Class B preferred stock, none of which is outstanding.  Approval by
Exxon shareholders of the merger, including the related issuance of Exxon
Mobil common stock, as described under "The Merger Transaction--General" on
page I-14, is a condition to effecting the Exxon charter amendment, and
approval of the Exxon charter amendment is a condition to completing the
merger.

               Increase of Authorized Common Stock.  Exxon's charter currently
authorizes three billion shares of common stock and 200 million shares of
preferred stock.  On March 1, 1999, 2,427,925,038 shares of Exxon common stock
were issued and outstanding, not counting shares held in Exxon's treasury.

               To complete the merger, Exxon expects that approximately 1.03
billion Exxon Mobil shares will be required to be issued to holders of Mobil
common stock and that approximately 67.5 million Exxon Mobil shares will be
required to be reserved for issuance under Mobil employee stock options and
other stock-based awards and for similar purposes.

               As these numbers show, the three billion shares of common stock
currently authorized under Exxon's charter will not be sufficient to complete
the merger.  We therefore ask Exxon shareholders to approve the amendment,
which will change Article FOURTH of Exxon's charter to increase the number of
authorized shares of Exxon common stock from 3 billion to 4.5 billion.

               The increased number of authorized shares will give Exxon
sufficient shares to complete the merger.  At present, Exxon has no plans to
issue shares for any other purpose.  However, we believe it is desirable to
have additional shares available for other corporate purposes that might arise
in the future.  For example, although Exxon currently meets its obligations to
deliver shares under employee stock options and similar arrangements with
treasury shares (meaning previously issued shares that have been reacquired by
Exxon), it may become desirable in the future to use newly issued shares for
this purpose.  Shares could also be used for acquisitions or to raise capital.
Under some circumstances, it is also possible for a company to use unissued
shares for antitakeover purposes, but Exxon has no present intention to take
any such action.

               Whether or not any future issuance of shares unrelated to the
merger would be submitted for shareholder vote depends upon the nature of the
issuance, legal and stock exchange requirements, and the judgment of Exxon's
Board at the time.

               Name change.  The merger agreement provides that, when the
merger takes effect, Exxon's name will be changed from "Exxon Corporation" to
"Exxon Mobil Corporation".  The proposed amendment implements this change to
Article FIRST of Exxon's charter.

               Elimination of Class B Preferred Stock.  Exxon's charter
currently authorizes the issuance of 100 million shares of Class B preferred
stock.  This class of stock was created in connection with Exxon's ESOP but
has never been issued and is no longer useful.  The proposed amendment of
Exxon's charter will eliminate the Class B preferred stock.

Transfer Agent and Registrar

               BankBoston, N.A. is the transfer agent and registrar for the
Exxon common stock.

Stock Exchange Listing; Delisting and Deregistration of Mobil Common Stock

               It is a condition to the merger that the shares of Exxon Mobil
common stock issuable in the merger be approved for listing on the NYSE at or
prior to the closing, subject to official notice of issuance.  If the merger is
completed, Mobil common stock will cease to be listed.  The Exxon Mobil ESOP
preferred stock will not be listed on any stock exchange.


                               LEGAL MATTERS

               The validity of the Exxon Mobil common stock to be issued to
Mobil shareholders pursuant to the merger will be passed upon by Charles W.
Matthews, Jr., General Counsel of Exxon.  It is a condition to the completion
of the merger that Exxon and Mobil receive opinions from Davis Polk & Wardwell
and Skadden, Arps, Slate, Meagher & Flom LLP, respectively, with respect to
the tax treatment of the merger.  See "The Merger Agreement--Conditions to the
Merger" and "The Merger--Material Federal Income Tax Consequences of the
Merger."

                   OTHER EXXON ANNUAL MEETING PROPOSALS


BOARD OF DIRECTORS PROPOSAL: ELECTION OF DIRECTORS (Item 3 on Exxon's Proxy
Card)

     The Exxon Board has nominated the director candidates named below.
Personal information on each of our nominees is given below. All of our
nominees currently serve as Exxon directors. Each current director was elected
by shareholders at the last annual meeting except for Mr. Esrey, who was
elected by the Board in July 1998.

     The Board of Directors performs a number of services for Exxon and its
shareholders including:

       o overseeing the management of the company on your behalf,
       o reviewing Exxon's long-term strategic plans,
       o exercising direct decision-making authority in key areas, such as
         declaring dividends,
       o choosing the CEO, setting the scope of his authority to manage the
         company's business day to day and evaluating his performance, and
       o reviewing development and succession plans for Exxon's top executives.

     Most Exxon directors -- including nine of our 13 nominees -- are not Exxon
employees. Only nonemployee directors serve on Exxon's Audit, Board
Compensation, and Board Affairs committees. All Exxon directors are elected for
one-year terms. Nonemployee directors may not stand for election after age 70.
Employee directors usually leave the Board when they retire from Exxon.

     The Board was saddened by the death on July 8, 1998 of Mr. D. Wayne
Calloway, who served as a director since 1988. His wise counsel will be missed.

     The Board met 10 times during 1998. All of Exxon's current directors
attended 100% of Board and committee meetings during the period they were
directors.

     If a director nominee becomes unavailable before the election, your proxy
authorizes us to vote for a replacement nominee if the Board names one.

The Board recommends you vote FOR each of the following candidates:

Chapter Four - Other Exxon Annual Meeting Proposals


Director Compensation

      Exxon employees receive no extra pay for serving as directors.
   Nonemployee directors receive a base fee of $40,000 a year; $1,500 per
   Board and committee meeting attended; and reimbursement of meeting
   expenses. Except for the Executive Committee, nonemployee directors also
   receive $3,000 per committee membership and $5,000 per committee
   chairmanship.  Nonemployee directors may elect to defer all or part of
   these fees.  Deferred fees are payable after the director leaves the Board
   in one to five annual installments.  We credit deferred fees with interest
   at Citibank's prime rate.

      We also pay a portion of director compensation in stock. Each
   nonemployee director receives 4,000 shares of restricted stock when first
   elected to the Board and, if the director remains in office, an additional
   600 restricted shares each following year. While on the Board, the
   nonemployee director receives the same cash dividends on restricted shares
   as a holder of regular common stock, but the director is not allowed to sell
   the shares.

Board Committees

      The Board appoints committees to help carry out its duties. In
   particular, Board committees work on key issues in greater detail than
   would be possible at full Board meetings. Each committee reviews the
   results of its meetings with the full Board.

   Audit Committee

      Mr. Houghton (Chairperson)
      Mr. Esrey
      Mr. Howell
      Dr. King
      Mrs. Nelson

      The Audit Committee met three times during 1998.  The committee is
   responsible for accounting and internal control matters. Subject to
   shareholder approval, the committee chooses the independent public
   accountants to audit Exxon's financial statements. The committee consults
   with the independent accountants and reviews their audit and other work.
   The committee also consults with Exxon's Controller and General Auditor and
   reviews Exxon's internal controls and compliance with policies. In addition
   to its regular activities, the committee is available to meet on call of
   the independent accountants, Controller, or General Auditor whenever a
   special situation arises.

   Board Advisory Committee on Contributions

      Mr. Hay (Chairperson)
      Mr. Esrey
      Dr. King
      Mr. Lippincott
      Mrs. Nelson
      Mr. Wilhelm

      The Board Advisory Committee on Contributions met two times during 1998.
   The committee reviews the level of Exxon's support for education and other
   public service programs, including the company's contributions to the Exxon
   Education Foundation. The Foundation works to improve the quality of
   education in America at all levels, with special emphasis on math and
   science.

      Dr. Boskin
      Mr. Esrey
      Mr. Houghton
      Mr. Shipley

Chapter Four - Other Exxon Annual Meeting Proposals


Board Compensation Committee Report on Executive Compensation

   Overview

      Exxon's executive compensation program is designed to motivate, reward,
   and retain the management talent our company needs to achieve its business
   goals and maintain its leadership.  Our program makes a significant portion
   of senior executives' potential compensation dependent upon increases in
   shareholder value.

      Exxon's success depends on retaining and motivating executives who have
   developed the skills and expertise required to lead a global organization.
   We do this with:

       o   Competitive base salaries in keeping with a philosophy of career
           continuity
       o   Rewards for exceptional performance and accomplishments
       o   Incentives to meet short-term and long-term objectives

      The nature of the petroleum business requires long-term and
   capital-intensive investments.  These investments often take years to
   generate a return to shareholders.  Accordingly, we grant incentive awards
   with a view toward long-term corporate performance.  These awards may not
   fluctuate as much as year-to-year financial results.

      Exxon pays for performance based on an individual's level of
   responsibility.  For this purpose, performance means both individual and
   corporate performance.  We motivate performance by recognizing the past
   year's results and by providing incentives for further improvement in the
   future.

      Individual performance includes the ability to put Exxon's business
   plans into effect and to react to unanticipated events.  We base
   compensation decisions for all executives, including the Chief Executive
   Officer (CEO) and the other executives named in the Summary Compensation
   Table on page IV-14 on these criteria.

      The three major components of Exxon's compensation program are base
   salary, short term incentive awards, and long term incentive awards.

   Base Salary

      In keeping with the long-term and highly technical nature of Exxon's
   business, we take a long-term approach to management development.  This
   career-oriented philosophy requires a competitive base salary.

      Each year, we adjust Exxon's salary structure based on competitive
   positioning (comparing Exxon's salary structure with salaries paid by other
   companies); Exxon's own business performance; and general economic factors.
   Specific weights are not given to these factors, but competitive
   positioning is the most important factor.  Business and other economic
   factors, such as net income and estimates of inflation, are secondary
   considerations.

      We use a number of surveys to determine Exxon's competitive salary
   position.  Primarily, we compare our salary structure with the U.S.-based
   oil companies in the industry group used for comparing stock performance on
   page IV-18.  We do not consider salary data from the foreign-based oil
   companies in that group.  Their executive compensation structures are not
   considered comparable.

      Exxon's business, and the competition for executives, extend beyond the
   oil industry.  Therefore, we also compare our salary structure with other
   major U.S.-based corporations.

                                     IV-10
<PAGE>

                           Chapter Four - Other Exxon Annual Meeting Proposals


      Exxon is larger and more diverse than the other surveyed companies.
   Therefore, Exxon targets its salary ranges between the median and high end
   of the survey data.  Within these ranges, we determine individual executive
   salaries based on individual performance, level of responsibility, and
   experience.  The BCC recommends the CEO's salary to the Board of Directors,
   sets the salaries for Exxon's other elected officers, and reviews the
   salaries of other senior executives.

   Short Term Incentive Awards

      Short term incentive awards consist of cash bonuses and Earnings Bonus
   Units (EBUs).  See page IV-16 for a description of the terms of EBUs.  We
   grant short term awards to executives to reward their contributions to the
   business during the past year.  We also grant EBUs as incentives for
   strong, mid-term corporate performance.  EBUs help stress that decisions
   and contributions in any one year affect future years.  In 1998,
   approximately one half of executive bonuses were in the form of EBUs.   The
   cumulative earnings required for maximum payout of each EBU granted this
   year was the same as that for last year.

      Each year, the BCC establishes a ceiling for cash bonuses and EBUs.  The
   ceiling for 1998 was $60 million.  Almost all of that amount was granted in
   awards to approximately 1,000 employees.  The ceiling is based on Exxon's
   business performance, progress towards long-term goals, and competitive
   position.  No particular formula is used.  Some of the measures of
   performance considered by the BCC include net income, earnings per share,
   return on capital employed, return on equity, and dividends.  The BCC does
   not give specific weights to these measures.  The 1998 ceiling was reduced
   from the 1997 ceiling.  In reaching this decision, no formula was used.
   The BCC considered several factors, including Exxon's financial performance
   (which, while strong relative to its major competitors in a difficult
   business environment, was still down relative to last year's record level),
   its continued strengthening of its worldwide competitive position and its
   progress towards long-range strategic goals.

      The bonus an executive receives depends on the executive's individual
   performance and level of responsibility.  Each year, we assess relative
   performance based on factors including initiative, business judgment,
   technical expertise, and management skills.

   Long Term Incentive Awards

      Long term incentive awards are intended to develop and retain strong
   management through share ownership and incentive awards that recognize
   future performance.  Stock options were the primary long term incentive
   granted to executive officers and over 3,500 other key employees in 1998.
   The parameters, guidelines, and administration of the 1998 grants were the
   same as those used for the 1997 grants.  The BCC believes that a
   significant portion of senior executives' compensation should depend on
   value created for the shareholders.  Options are an excellent way to
   accomplish this because they tie the executives' interests directly to the
   shareholders' interests.  See page IV-15 for a description of the terms of
   options.

      The number of options granted to executive officers is based on
   individual performance and level of responsibility.  For this purpose, the
   Committee measures performance the same way as described above for short
   term awards.  Option grants must be sufficient in size to provide a strong
   incentive for executives to work for long-term business interests and
   become significant owners of the business.  The number of options held by
   an executive is not a factor in determining subsequent grants.  Granting
   options on that basis could create an incentive for executives to exercise
   options and sell their shares.

      The Company does not have required levels for equity holdings by senior
   management, but long-term awards are designed to encourage share ownership.
   The five officers named in the Summary Compensation Table on page IV-14
   have, on average, equity holdings of approximately 14 times salary as of
   year-end 1998.  In addition, other elected officers have holdings which
   exceed typical ownership guidelines used by some companies in industry.

Chapter Four - Other Exxon Annual Meeting Proposals


      Last year, the BCC granted Career Shares to a limited number of senior
   executives.  Career Shares are shares of Exxon common stock that normally
   may not be sold until after an executive reaches normal retirement age.
   The shares may be forfeited if an executive leaves before that time.  Given
   the size, complexity, and global scope of Exxon's business, it is essential
   to retain an experienced senior management team.  Career Shares help Exxon
   retain key strategic and operating executives for the long term.  These
   awards also provide an additional incentive for superior long-term
   corporate performance.  The number of Career Shares granted to senior
   executives also reflects the increased responsibility and complexity of
   senior positions.

      The Committee bases individual Career Share grants on the executive's
   personal contribution and level of responsibility.  The number of shares
   held by an executive is not a factor in determining individual grants since
   Career Shares are primarily designed to promote long-term retention.

   U.S. Income Tax Limits on Deductibility

      U.S. income tax law limits the amount Exxon can deduct for compensation
   paid to the CEO and the other four most highly paid executives.
   Performance-based compensation that meets IRS requirements is not subject
   to this limit.  The short term awards and stock option grants described
   above are designed to meet these requirements so that Exxon can continue to
   deduct the related expenses.  Specifically, the shareholders have approved
   broad performance measures for short term awards to the top executives.
   The shareholders also set limits on short term awards to these executives
   (0.2% of operating net income) and on individual option grants (0.2% of
   outstanding shares at year-end 1996, adjusted for stock splits).  These are
   not targets, only maximums established for deductibility purposes.  Actual
   award levels have been significantly less based on the factors and
   judgments described in the preceding sections of this report.

   CEO Compensation

      Within the framework described above, the BCC determines the CEO's
   compensation by judging his individual contributions to Exxon's business,
   level of responsibility, and career experience. The BCC does not think
   narrow quantitative measures or formulas are sufficient for determining Mr.
   Raymond's compensation.  The Committee does not give specific weights to
   the factors considered, but the primary factor is the CEO's individual
   contributions to the business.

      The Committee also considers Exxon's size, complexity, and business
   results as compared to its competitors in the industry and other major
   U.S.-based corporations outside the industry.  The BCC believes the
   combination of Mr. Raymond's base salary and short-term awards is
   appropriate compared to CEOs of Exxon's competitors.

      Mr. Raymond's long-term incentive awards reflect his level of
   responsibility, his leadership, and the BCC's judgment of his overall
   contribution as CEO.  In making this determination, the BCC considered the
   complex, highly technical, and long-term nature of Exxon's business.  The
   Career Share award granted to Mr. Raymond recognizes his outstanding
   contributions to Exxon's business performance, continued strengthening of
   the Corporation's worldwide competitive position, and its progress toward
   long-range strategic goals.  The restrictions on the award are designed to
   retain his leadership for the remainder of his career.

   Summary

      The BCC is made up of nonemployee directors who do not participate in
   any of the compensation plans they administer.  The BCC approves or
   endorses all the programs that involve compensation paid or awarded to
   senior executives.

      The BCC is responsible for seeing that Exxon's compensation program
   serves the best interest of its shareholders.  To help meet this
   responsibility, the BCC is guided by an independent analysis of the
   competitiveness of Exxon's executive compensation.  This analysis is
   prepared each year by a leading public accounting firm.  The BCC also
   considers the results of the salary surveys described above.

      In the opinion of the Committee, Exxon has an appropriate and
   competitive compensation program.  The combination of sound base salary,
   competitive short term bonuses, and emphasis on long term incentives
   provides a balanced and stable foundation for effective executive
   leadership.

  (1) Number of restricted shares times the market price of Exxon stock on
      the day of grant.  As of December 31, 1998, the total number and
      value of restricted shares held by these executives were:  Mr.
      Raymond: 280,000 shares ($20,475,000);  Mr. Dahan: 46,000 shares

      Wilhelm: 48,000 shares ($3,510,000); and Mr. Nesbitt: 18,000 shares
      ($1,316,250).  The values given do not reflect the fact that the
      shares are restricted.  The executives receive the same cash
      dividends on restricted shares as holders of regular common stock,
      but cannot sell the shares during the restricted period.  See page
      IV-12 for more information on these shares, which we call Career
      Shares.

  (2) Settlements of Earnings Bonus Units. See page IV-16 for more details.

   maximum settlement value of $4.50 per unit is reached, if earlier.
   SEC rules classify EBUs as long-term incentives, but because of the

*  For plan purposes, this means (1) average annual salary over the

   employment, plus (2) the average of the three highest cash bonus
   and EBU awards during the employee's last five years of employment.

      Employees who meet the age, service, and other requirements of Exxon's
   annuity plans are eligible for an annuity (or pension) after retirement.
   The table shows the approximate yearly annuity that would be paid to an

   the employee's Social Security benefits.

BOARD OF DIRECTORS PROPOSAL: RATIFICATION OF INDEPENDENT ACCOUNTANTS (Item 4
on Exxon's proxy card)

      The Audit Committee of the Board has appointed PricewaterhouseCoopers
   LLP (PwC) to audit our financial statements for 1999. We are asking you to
   ratify that appointment.

      PwC (as successor to Price Waterhouse LLP) has been Exxon's independent
   accounting firm for many years, and we believe they are well qualified for
   the job. A PwC representative will be at the annual meeting to answer
   appropriate questions and to make a statement if he desires.

      The Board recommends you vote FOR this proposal.

SHAREHOLDER PROPOSALS (Items 5 through 8 on Exxon's proxy card)

      We expect the following proposals to be presented by shareholders at the
   annual meeting. Following SEC rules, we are reprinting the proposals and
   supporting statements as they were submitted to us. We take no
   responsibility for them. On request to the address under "The Companies" on
   page I-2, the Secretary will provide information about the shareholdings of
   the proposal sponsors.

      The Board recommends you vote AGAINST these proposals for the reasons we
   give after each one.

Shareholder Proposal: Term Limit for Nonemployee Directors (Item 5 on Exxon's
proxy card)

      This proposal was submitted by Mrs. Evelyn Y. Davis, Watergate Office
   Building, 2600 Virginia Avenue, N.W., Suite 215, Washington, DC 20037.

      "RESOLVED, That the stockholders of Exxon recommend that the Board take
   the necessary steps so that future outside directors shall not serve for
   more than six years."

      REASONS:  "The President of the U.S.A. has a term limit, so do Governors
                of many states.

                Newer directors may bring in fresh outlooks and different
                approaches with benefits to all shareholders.

                No director should be able to feel that his or her
                directorship is until retirement.

                If you AGREE, please mark your proxy FOR this resolution."

      The Board recommends you vote AGAINST this proposal for the following
   reasons:

      The Board believes that its current practices and those of the Board
   Affairs Committee concerning the nomination and service of directors ensure
   a balanced Board where individuals with diverse backgrounds, knowledge, and
   experience function well as a unit.

      The Board Affairs Committee, which is comprised only of nonemployee
   directors, recommends candidates for Board membership to the full Board of
   Directors.  The Committee annually develops a proposed slate of nominees
   which the Board must approve to be voted on by all shareholders.
   Shareholders vote every year on each of the directors.  Historically, over
   99% of the shareholders voting have voted in favor of each of the directors
   standing for election for any given year.  In developing and recommending
   candidates, the Committee considers the overall needs of the Board, such as
   continuity and depth of knowledge and experience, as well as an
   individual's ability to contribute.

                                     IV-19
<PAGE>

Chapter Four - Other Exxon Annual Meeting Proposals


      Arbitrarily imposing a maximum of six years service for future
   nonemployee directors could result in the premature loss of directors who
   have acquired a great deal of knowledge and perspective about the company's
   operations and who may be in a position to make their most valuable
   contributions to Exxon's business.

      A similar proposal was submitted by this proponent for the 1985 Annual
   Meeting, and almost 97% of shareholders voting, voted AGAINST it.

Shareholder Proposal: Limitation on Shareholder Voting (Item 6 on Exxon's
proxy card)

      This proposal was submitted by Mr. J. F. Quilter, 500 Westridge Drive,
   Portola Valley, CA  94028-7721.

      "WHEREAS it is the usual practice for annual stockholders' meeting
   announcements to include a statement to the effect that if no direction is
   made the proxy will be voted for the nominations made or positions held by
   management.

      This clouds the voting results as to votes for directors and auditors,
   does not accurately reflect the desires of voting stockholders and skews
   the results.  In a political election it would be tantamount to counting
   votes of those who do not vote as being in favor of the incumbent.

      THEREFORE IT IS RESOLVED, That the shareholders recommend that the Board
   of Directors take the necessary action to cause proxy balloting on nominees
   and items contained in the notice of the annual meeting to be tabulated for
   each nominee and proposal as in favor, opposed, abstain and returned
   unmarked.  The decision shall be determined by the number of those voted in
   favor and opposed.

      Unmarked ballots shall be considered only for the demonstration of a
   quorum.

      For each nominee and proposal, stockholders shall be advised of the
   official results in the normal course of communication with stockholders."

      The Board recommends you vote AGAINST this proposal for the following
   reasons:

      Exxon uses the same proxy voting procedure as the vast majority of other
   public corporations.  For Exxon to use a different procedure could result
   in unnecessary confusion.

      The proposal would deprive shareholders of a simple, easily understood
   way to vote for all of the Board of Directors' recommendations.  It is
   based on the assumption that shareholders do not read or understand the
   clearly explained voting instructions.

      Exxon's proxy card provides shareholders the option to vote for,
   against, or to abstain on all items of business except the election of
   directors.  In the case of directors, the shareholders may vote for or
   against each director.  The proponent of this proposal assumes that
   shareholders who sign and return their proxy cards without marking specific
   items do not intend to cast their votes.  It seems more likely that
   individuals who wish to be counted for quorum purposes, but do not want to
   vote on specific items, would simply mark "abstain".

      The proxy card states in boldface letters that "If no other indication
   is made, the proxies shall vote (a) for the election of the director
   nominees and (b) in accordance with the recommendations of the Board of
   Directors on the other matters referred to on the reverse side."  The Board
   believes that shareholders read proxy card instructions, understand this
   long-time practice, and fully intend to cast their votes in accordance with
   the instructions by simply and conveniently signing and returning the card.

                           Chapter Four - Other Exxon Annual Meeting Proposals


Shareholder Proposal: Additional Report on Climate Change (Item 7 on Exxon's
proxy card)

      This proposal was submitted by The Province of St. Joseph of the
   Capuchin Order, 1015 North Ninth Street, Milwaukee, WI 53233 and twenty
   co-proponents.

      "WHEREAS, this resolution's proponents are convinced overwhelming
   scientific evidence demonstrates that fossil fuel burning contributes to
   global warming.

          -- Despite this evidence, Exxon's management has led efforts
             which, we believe, undermine national and international
             responses addressing the problem:

          1. At last year's annual meeting shareholders had the
             opportunity to vote on the same resolution contained on these
             pages.  However Lee R. Raymond stated (in regard to climate
             change): "What is perfectly clear is that 'nothing is clear.'
             There needs to be continuing public debate." On the one hand,
             management says it wants a debate; on the other, it has gone
             to the Securities and Exchange Commission trying to keep
             shareholders from voting on this resolution.

          2. The proponents of this resolution believe management's
             position is inaccurate, short-sighted and potentially damaging
             to the long-term financial interests of this company.

          3. Last year, management urged shareholders to vote against the
             resolution, claiming without substantiation that "cuts in
             fossil fuel use ... would severely damage economies, industry
             and jobs." Yet 2000 economists have stated "the United States
             would be able to reduce its emissions to slow global warming
             without damaging the economy" (WP 2/14/97).

          4. We believe that management is part of a large-scale and
             highly-funded effort which is attempting to undermine existing
             public policy attempts to address the issue of human causation
             of global warming.

          5. The top two U.S. automobile companies have begun to make
             changes in their products which recognize the need to have less
             emissions from the burning of fossil fuels.

          6. Two of the largest European fossil fuel companies, Royal
             Dutch Shell and British Petroleum, have already begun making
             decisions for their long-term growth which factor in the
             conclusions of the scientific community warning about the
             effect of fossil fuel combustion on climate change.  John
             Browne, Group Chief Executive of BP America has stated: "The
             time to consider the policy dimensions of climate change is
             ... when the possibility cannot be discounted. ...  We in BP
             have reached that point."

          -- Such an admission from an executive of a major competitor in
             the fossil fuel industry should have led Exxon's management to
             seriously re-examine the issue.  Despite this, management
             continues to share with concerned shareholders and others only
             those opinions of scientists that agree with management's
             position.  Many of these studies and/or scientists have been
             funded by management.  We know of no case where such
             "evidence" regarding the burning of fossil fuels and climate
             change being proffered by such scientists has been subject to
             peer review.

      RESOLVED, Shareholders request the Board to create a committee of
   outside directors to independently review and issue (at reasonable cost and
   omitting proprietary information) a full report to shareholders by August,
   1999 regarding the impact of climate change on our company's policies and
   practices.  We recommend the following issues to be included:  1) any
   anticipated liabilities Exxon may incur from its possible contribution to
   the problem;  2) what Exxon can do to reduce carbon dioxide emissions from
   our fossil fuels.

      If you agree, please vote 'yes' for this resolution."

Chapter Four - Other Exxon Annual Meeting Proposals


      The Board recommends you vote AGAINST this proposal for the following
   reasons:

      A similar proposal was presented by this same proponent at Exxon's 1998
   annual meeting and was rejected by shareholders owning more than 95 percent
   of the shares voted.

      The proposal calls for a new Board committee to study global climate
   change.  The Board believes such a committee would be an unwarranted
   duplication of effort since it is already kept well informed about this
   issue.  The proposal also calls for a special report despite extensive,
   ongoing communications on this subject.  Exxon already provides information
   to shareholders, employees, and the public through publications such as the
   annual report, The Lamp, Perspectives, special information booklets such as
   Global Climate Change:

   Everyone's Debate, and Exxon Initiatives Related to Global Climate, and
   executive speeches.  These and other sources of information are available
   on Exxon's website (www.exxon.com).

      Regrettably, in attempting to justify this proposal, the proponent has
   chosen to engage in personal allegations rather than address the major
   scientific, technical, economic, and social issues involved in the global
   climate change debate.  The fact that Exxon's views are different from the
   proponent's is not an appropriate basis to characterize Exxon as
   "undermining public policy."

      Contrary to the proponent's claim, there is a broad range of interested
   and informed parties such as business, labor, consumer, agriculture, and
   other groups that, along with Exxon, are participating in legitimate public
   debate on this issue.  This does not undermine public policy.  It is an
   important component of the democratic process.  Indeed, the views of most
   participants are similar to those of the U.S. Senate as expressed in Senate
   Resolution 98.  The Senate passed (by a vote of 95-0) a resolution that the
   United States should not agree to a treaty that does not include specific
   mandated commitments by all nations or that would result in serious harm to
   the economy of the United States.

      Similarly, statements by the proponent that scientific studies cited by
   Exxon are only those "funded by management" and have not been "subject to
   peer review" are incorrect.  This is particularly disappointing since we
   have offered the proponent an opportunity to talk with numerous technical
   and economic experts.  Had the proponent done so, it would have found that,
   contrary to the above assertion, the company has indeed cited numerous
   peer-reviewed studies in its communications regarding climate change.

      Earth's climate is affected by many complex variables.  Throughout
   history, climate has fluctuated between periods of cooling and periods of
   warming.  Some of those changes lasted hundreds of years, others hundreds
   of thousands.  Over the past century, there has been a slight warming trend
   of one-half degree Celsius (about one degree Fahrenheit).  This recent
   warming trend falls well within the range of the natural changes in the
   Earth's temperature over the past 250,000 years.  The debate about climate
   change concerns whether this recent warming is primarily connected with our
   use of fossil fuels - coal, oil, and natural gas.

      Scientists concerned about global warming point to the greenhouse
   effect, a proven natural phenomenon.  Water vapor and carbon dioxide
   (CO(2)) and other gases trap some of the sun's energy, creating a warming,
   or greenhouse effect.  Nearly all CO(2) emissions come from natural
   sources.  Only a small amount comes from burning fossil fuels.  Does the
   tiny portion of greenhouse gases caused by burning fossil fuels have a
   measurable effect on worldwide climate?  That is the crux of the debate.

      In December 1997, representatives from many governments attended
   meetings in Kyoto, Japan.  The outcome of the meetings was a treaty which,
   if ratified, would commit certain countries to reduce CO(2) and other
   greenhouse gas emissions.  The agreement would commit 38 developed
   countries, including the United States, to reduce their combined emissions
   an average of five percent below 1990 levels in the next 10 to 14 years.
   But the treaty excludes more than 130 developing countries from any
   commitments.  It also left many implementation questions unanswered and
   little progress has been made since then in resolving these questions or in
   meeting the standards established by the Senate resolution.

                           Chapter Four - Other Exxon Annual Meeting Proposals


      The published, peer-reviewed economic literature shows that the
   financial and social impact of these substantial, mandated fossil fuel
   reductions (through taxes, rationing, or other measures) would severely
   damage economies, industry, and jobs.  Independent economists project
   that the targeted reductions in fossil-fuel would require price
   increases such as 40 percent for gasoline, 50 percent for home heating
   oil, 25 percent for electricity, and 50 percent for natural gas.  These
   and other price hikes could cost the average American family of four
   about $2,700 a year.  This work was confirmed by a government analysis
   (U.S. Department of Energy's Energy Information Administration-October
   1998) which projects that meeting this target could increase U.S. energy
   prices by up to 83 percent and cost the economy over $300 billion
   annually.

      Excluding developing nations from such reductions, which renders the
   Kyoto targets largely ineffective, will not prevent those countries from
   being hurt.  Their exports will suffer as the economic growth of
   industrialized nations is impaired.  In developing nations, reducing
   economic growth would mean fewer financial resources available for
   meeting real and immediate social needs, such as reduced poverty, clean
   drinking water, health care, and education.

      The potential for climate change caused by elevated levels of CO(2) in
   the atmosphere is a legitimate concern, and reducing the scientific
   uncertainties is important.  The public should support additional research
   on this issue.  Industries should continue voluntary market-driven efforts
   to identify cost-effective ways to reduce energy use and emissions.  Exxon
   and others are already working in areas such as energy efficiency and fuel
   switching-which means, for example, changing from coal to cleaner-burning
   natural gas.  At Exxon, our refineries and chemical plants are 35 percent
   more energy-efficient today than they were 25 years ago.  In addition, we
   operate or have an interest in 26 cogeneration plants around the world.
   Cogeneration makes steam and electricity simultaneously, using 30 percent
   less energy than making them separately.

      Advanced technology is one of the main tools industry is applying to
   reduce energy use and, with it, CO(2) emissions.  Long-term research should
   continue to render substantial improvements - 50 percent to 100 percent--in
   energy efficiency.  For example, Exxon is involved in several partnerships
   to develop advanced technology for greatly improved efficiency in
   transportation.

      Fortunately, all indications are that climate change is a very long-term
   phenomenon.  The U.S. Congressional Office of Technology Assessment
   concluded, "Delaying the implementation of emissions controls for 10 to 20
   years will have little effect on atmospheric concentrations of greenhouse
   gas emissions."  We can make good use of that time.  Researchers will be
   able to gain a better understanding of climate science.  And there is a lot
   of research going on - about $2 billion worth a year in the U.S. alone.
   Exxon itself has funded studies by several major research organizations.

      Exxon believes that sound science and sound economics should light the
   way as society addresses climate change.  Patience is important as we allow
   facts to guide our course of action.  With such an approach, the world can
   resolve global climate change in a way that also keeps economies healthy
   and growing.  But the first step is an open and honest debate on the issue.
   Creating another Board committee and adding another special report are
   unnecessary, duplicative, and wasteful since the issue of global climate
   change is reviewed frequently with the full Board of Directors, the company
   has already produced extensive communications, and is committed to continue
   speaking out on this important matter.

Chapter Four - Other Exxon Annual Meeting Proposals


Shareholder Proposal: Sexual Orientation Principles (Item 8 on Exxon's proxy
card)

      This proposal was submitted by Ms. Marianne Weil, Box 341, Orient, New
   York 11957 and three co-proponents.

      "WHEREAS, our Company has pledged its commitment to principles of
   non-discrimination, but has not in written form explicitly barred
   discrimination based on sexual orientation;

      WHEREAS, employment discrimination and the denial of equal benefits on
   the basis of sexual orientation diminishes employee morale and productivity;

      WHEREAS, a National Gay and Lesbian Task Force study revealed that
   between 16% and 44% of gay men and lesbians in twenty cities nationwide
   have experienced some form of workplace harassment or discrimination
   related to their sexual orientation;

      WHEREAS, San Francisco, Atlanta and New York have adopted and other
   jurisdictions are considering adopting legislation restricting business
   with companies which do not guarantee equal treatment for lesbian and gay
   employees;

      WHEREAS, our company has operations in and makes sales to public
   institutions in states and cities which prohibit discrimination on the
   basis of sexual orientation;

      WHEREAS, stakeholders in our company have an interest in preventing
   discrimination and resolving complaints internally to avoid costly
   litigation or damage to our reputation as an equal opportunity employer;

      WHEREAS, numerous major companies in the petroleum and energy industries
   have written policy barring sexual orientation discrimination;

      WHEREAS, the hundreds of corporations that have adopted sexual
   orientation non-discrimination policies - including over 100
   publicly-traded companies also providing spousal benefits to same-sex
   partners of employees - place themselves in a more competitive position to
   recruit and retain employees from the widest available pool of talent;

      WHEREAS, national polls have consistently found more than three-quarters
   of Americans support equal rights in the workplace for gay men, lesbians
   and bisexuals;

      WHEREAS, prominent gay and lesbian political and community leaders have
   proposed "The Equality Principles on Sexual Orientation" to serve as
   guidelines for corporate policies:

   1. Explicit prohibitions against discrimination based on sexual
      orientation will be included in the company's written employment policy
      statement.

   2. Discrimination against HIV-positive employees or those with AIDS
      will be strictly prohibited.

   3. Employee groups, regardless of sexual orientation, will be given
      equal standing with other employee associations.

   4. Diversity training will include sexual orientation issues.

   5. Spousal benefits will be offered to domestic partners of employees,
      regardless of sexual orientation, on an equal basis with those
      granted to married employees.

                           Chapter Four - Other Exxon Annual Meeting Proposals


   6. Company advertising policy will bar negative sexual orientation
      stereotypes and will not discriminate against advertising in
      publications on the basis of sexual orientation.

   7. The Company will not discriminate in the sale of goods or services
      on the basis of sexual orientation.

   8. Written non-discrimination policies on sexual orientation must be
      disseminated throughout the company.  A senior company official will
      be appointed to monitor compliance corporate wide.

      RESOLVED, The Shareholders request the Board of Directors adopt and
   implement a written policy barring sexual orientation discrimination.

      SUPPORTING STATEMENT:  Sexual orientation discrimination is a morally
   wrong and self-defeating business practice.  By implementing an equitable
   policy, our Company will ensure a respectful and supportive atmosphere for
   all employees and enhance its competitive edge by joining the growing ranks
   of energy companies guaranteeing equal opportunity for all employees.

      The Board recommends you vote AGAINST this proposal for the following
   reasons:

      Exxon believes that its current policies on "Equal Employment
   Opportunity" and "Harassment in the Workplace" already meet the proponent's
   stated objective that the Corporation adopt a written policy barring
   discrimination based on the grounds of sexual orientation.

      When this issue was raised at last year's Annual Meeting of
   Shareholders, Mr. Lee Raymond, Chairman and Chief Executive Officer of the
   Corporation, stated that ". . .  we have a policy to not discriminate
   against anybody for any reason, period."

      It has been Exxon's long-standing policy and practice to not tolerate
   discrimination or harassment of any kind in the workplace.  Earlier this
   year, an updated "Harassment in the Workplace Policy" was issued to confirm
   and strengthen those underlying objectives.  It provides in part:

         "It is the policy of Exxon Corporation to prohibit any form of
         unlawful harassment based on race, color, sex, religion, national
         origin, citizenship status, age, physical or mental disability or
         veteran status.  In addition, the Corporation's harassment policy
         prohibits any other form of harassment.  Such conduct, while perhaps
         not unlawful is considered unacceptable in Exxon's workplace."

      It is Exxon's practice to list as forms of harassment in its policies
   only those which are specifically prohibited by federal law.  To name all
   possible examples of harassment could provide a long list which would only
   divert attention from the basic need for a harassment-free workplace.  The
   revised language in the Harassment Policy makes it clear that "any other
   form of harassment" is prohibited. The Harassment Policy goes on to broadly
   define harassment as follows:

      "Harassment is any inappropriate conduct which has the purpose or effect
   of:

      o   Creating an intimidating, hostile, or offensive work environment;
      o   Unreasonably interfering with an individual's work performance; or
      o   Affecting an individual's employment opportunity."

      This definition of "harassment" and the language prohibiting harassment
   of any kind provide for a broad anti-discrimination policy that clearly
   encompasses discrimination on the basis of sexual orientation in the
   workplace. The Harassment Policy also sets forth the procedures for
   individuals to follow in the event they believe that they have been
   subjected to harassment.  The Harassment Policy thus comprises a
   comprehensive

                                     IV-25
<PAGE>

Chapter Four - Other Exxon Annual Meeting Proposals


   anti-harassment policy that is applicable to individuals who have been
   subjected to harassment or discrimination on the basis of sexual
   orientation.

      In summary, the revised Harassment Policy makes it unequivocally clear
   that Exxon does not tolerate discrimination on any grounds, including
   sexual orientation.  Thus, the Corporation has already implemented a
   written policy barring sexual orientation discrimination, and there is no
   need to make the changes recommended by the proponent.


                               OTHER MATTERS

Section 16(a) Beneficial Ownership Reporting Compliance

      Section 16(a) of the Securities and Exchange Act of 1934 requires that
   our executive officers and directors file reports of their ownership and
   changes in ownership of Exxon stock on Forms 3, 4 and 5 with the SEC and
   the NYSE.  In 1998, Mr. Esrey's initial filing on Form 3 inadvertently
   failed to report ownership of 380 shares of Exxon common stock.  The error
   was corrected in a subsequent filing.

BOARD OF DIRECTORS PROPOSAL:  APPROVAL AND RATIFICATION OF APPOINTMENT OF
INDEPENDENT AUDITORS FOR FISCAL YEAR 1999 (Item 3 on Mobil's proxy card)

      The Mobil Board desires, in accordance with its established policy,
to obtain from you an indication of your approval or disapproval of the
Board's appointment of Ernst & Young LLP, Fairfax Square-Tower II, 8075
Leesburg Pike, Vienna, Virginia 22182-2709, as independent auditors of
Mobil and its subsidiaries for 1999.

      Ernst & Young LLP has been serving Mobil and its subsidiaries for
many years.  It has no direct financial interest or any material indirect
financial interest in Mobil or any of its subsidiaries.  While serving as
independent auditor, Ernst & Young LLP has had no connection with Mobil or
any of its subsidiaries as promoter, underwriter, voting trustee, director,
officer or employee.  During 1998, Ernst & Young LLP rendered audit
services amounting to $12.9 million.

      The Audit Committee recommended and the Mobil Board approved the
appointment of Ernst & Young LLP as independent auditors.  The Audit
Committee reviewed the performance of Ernst & Young LLP in prior years as well
as the firm's reputation for integrity and competence in the fields of
accounting and auditing, and the status of litigation involving the firm.  The
Audit Committee is satisfied with Ernst & Young LLP in these respects.

      Representatives of Ernst & Young LLP will be present at the Mobil
meeting to respond to appropriate questions from those of you attending the
meeting and to make such statements as they may desire.

                                      V-4
<PAGE>

                           Chapter Five - Other Mobil Annual Meeting Proposals


      The Mobil Board recommends you vote FOR the following
resolution which will be presented at the meeting:

            "RESOLVED, that the appointment, by the Board of Directors of
      the Corporation, of Ernst & Young LLP as independent auditors of the
      Corporation and its subsidiary companies, for fiscal year 1999, be
      and hereby is approved and ratified."

      If the resolution is defeated, the adverse vote will be considered a
direction to the Mobil Board to select other auditors for the following
year.  However, because of the difficulty and expense in making any
substitution of auditors so long after the beginning of the current year,
it is contemplated that the appointment for the year 1999 will be permitted
to stand unless the Mobil Board finds other good reasons for making a
change.

SHAREHOLDER PROPOSALS  (Items 4 and 5 on Mobil's proxy card)

      We expect the following proposals to be presented by shareholders at
the annual meeting.  Following SEC rules, we are reprinting the proposals
and supporting statements as they were submitted to us.  We take no
responsibility for them.

Shareholder Proposal: Voting of Signed but Unmarked Proxies  (Item 4 on
Mobil's proxy card)

      The following proposal was submitted by J.F. Quilter, 500
Westridge Drive, Portola Valley, California 94028, the owner of 1,352.6814
shares of Mobil common stock:

            WHEREAS, it is the usual practice for annual stockholders'
      meeting announcements to include a statement to the effect that if no
      direction is made the proxy will be voted for the nominations made or
      positions held by management.

            This clouds the voting results as to votes for directors and
      auditors, does not accurately reflect the desires of voting
      stockholders and skews the results.  In a political election it would
      be tantamount to counting votes of those who do not vote as being in
      favor of the incumbent.

            THEREFORE, it is RESOLVED that the shareholders recommend that
      the Board of Directors take the necessary action to cause proxy
      balloting on nominees and items contained in the notice of the annual
      meeting to be tabulated for each nominee and proposal as in favor,
      opposed, abstain and returned unmarked.  The decision shall be
      determined by the number of those voted in favor and opposed.

            Unmarked ballots shall be considered only for the demonstration
      of a quorum.

            For each nominee and proposal, stockholders shall be advised of
      the official results in the normal course of communication with
      stockholders.

      The Mobil Board recommends you vote AGAINST the adoption of
this proposal.

      As permitted by applicable laws and regulations, and consistent with the
practice of virtually all public corporations, Mobil advises shareholders
that if they sign, date and return their proxy cards without indicating how
they wish to vote, their proxies will be voted in accordance with the
Board's recommendations.  This entirely lawful and customary procedure
serves as a convenience to those shareholders who wish to vote on all
matters as management recommends.  The proponent asserts that the procedure
"clouds the voting results. . . , does not accurately reflect the desires
of voting stockholders and skews the results." However, it in no way
affects the rights of any shareholder to vote in opposition to management's
recommendations on any or all matters or to abstain from voting: a
shareholder need only mark the appropriate boxes on the proxy card to
record his or her votes.  Accordingly, the Mobil Board strongly disagrees
with the proponent's assertion.

Chapter Five - Other Mobil Annual Meeting Proposals


      For the foregoing reasons, the Mobil Board recommends you vote
AGAINST the adoption of the proposal.

Shareholder Proposal: Global Warming  (Item 5 on Mobil's proxy card)

      The following proposal was submitted by Friends of the Earth
Action, 1025 Vermont Avenue, NW #300, Washington, DC 20005-6303 and the
National Council of the Churches of Christ in the USA, 475 Riverside Drive,
New York, New York 10115-0050, which state that they are the holders of a
total of 5,858 shares of Mobil common stock, and six other shareholders who
state that they hold 60,900 shares of Mobil common stock in the aggregate and
whose names and addresses will be furnished on request:

            WHEREAS:

            The overwhelming majority of independent, peer-reviewed
      atmospheric scientists agree that global warming is not hypothetical
      but a real, existing problem posing serious challenges for modern
      civilization;

            The impacts of global warming on our public health and welfare
      include increased occurrence of extreme weather events, sea-level
      rise, increased spread of infectious diseases, and more frequent and
      deadly heat waves like the summer of 1998 which was linked to more
      than 150 deaths in Texas alone.

            British Petroleum and Royal Dutch Shell have already begun
      making decisions for their long-term growth which factor in the
      conclusions of the scientific community warning about the effect of
      fossil fuel combustion on climate change.  John Browne, Group Chief
      Executive of BP America has stated: "The time to consider the policy
      dimensions of climate change is...when the possibility cannot be
      discounted....  We in BP have reached that point."

            WE BELIEVE:

            It will cost U.S. taxpayers billions of dollars to combat the
      impacts of global warming.  So far, our company has not lived up to
      its responsibility as a producer of the pollution which causes global
      warming.  In order to leave the children of the world a safe and
      healthy environment, and protect threatened plants and animals, it is
      time for Mobil to catch up with other companies who are preparing for
      the future now by taking the concrete steps necessary to assess their
      opportunities for reducing the amount of carbon pollution they
      produce.  Failing to rise to the challenge set by industry leaders
      will hurt our company's competitiveness and cost our shareholders
      increasing amounts of money.

            RESOLVED: that the shareholders of Mobil request that the Board
      of Directors report (at reasonable costs and omitting proprietary
      information), to shareholders by August 1999, on the greenhouse gas
      emissions from our company's own operations and products, including
      (with dollar amounts where relevant)  (i) what our company is doing
      in research and/or action to reduce those emissions and ameliorate
      the problem, (ii) the financial exposure of our company and its
      shareholders due to the likely costs of reducing those emissions and
      potential liability for damages associated with climate change, and
      (iii) actions by our company, or by the industry associations to
      which it pays dues, promoting the view that the issue of climate
      change is exaggerated, not real, or that global warming may be
      beneficial.

      SUPPORTING STATEMENT

            We believe that Mobil is exposing its shareholders to financial
      risk by continuing to produce unnecessary amounts of the pollution
      which causes global warming, even as the problem of climate change
      becomes more severe, more widely understood, and more likely to lead
      to legislation that will penalize excessive carbon polluters.
      Furthermore, we believe that our company is incurring costs for
      advertising and lobbying to suggest that the problem of global
      warming is exaggerated, not real, or too costly to deal with; and
      thus using our prestige and influence to delay any lessening of
      climate change.

                           Chapter Five - Other Mobil Annual Meeting Proposals


      The Mobil Board recommends you vote AGAINST the adoption of this
proposal.

      Mobil has consistently communicated its view that all energy resources,
including our products, should be used wisely.  Furthermore, Mobil has
undertaken numerous energy-saving initiatives in the interest of maximizing
the efficiency of its operations.  Information on these measures, as well as
Mobil's position on global climate change, is already widely available in
publications such as Mobil's opinion-editorials appearing in major newspapers
and magazines worldwide, in Mobil's climate primer entitled, "Global Climate
Change:  Issues, Impacts and Solutions," in Mobil World, and in the special
global climate section of Mobil's web site which can be found at www.mobil.com.

      In addition, Mobil's Annual Environmental, Health and Safety Report will
include this year, for the first time, an inventory of carbon emissions
from Mobil's global operations in 1998.  These figures will also be
available on Mobil's web site.  Thus, the Mobil Board believes that Mobil
is fulfilling its obligations to the public and its shareholders by sharing
information on its views about, and its extensive activities relating to,
global warming.  Therefore, the Board recommends that you vote against this
proposal.

      Mobil has stated that it is concerned about the possible impacts of
human emissions of greenhouse gases on the world's climate.  However, Mobil
believes that a system of mandated emission targets as embodied in the
Kyoto Protocol is the wrong approach to addressing this issue.  The
magnitude and timing of potential climate change or the effectiveness of
proposed solutions and their impacts on the quality of life are not
understood.  Yet there are many voluntary steps that are being taken to use
our energy resources more wisely.  And there are promising technologies
that can make a sizeable difference in the future.

      We have also stated, "The choice at this time is not between action
and inaction, but between responsible actions and actions that put our
economy and business at risk." Mobil supports prudent voluntary cost-
effective actions now while learning more about climate change and the
possible responses to its effects.

      To enhance its learning about these issues, Mobil actively supports
climate change research programs at universities and leading institutions.
Mobil supports two efforts at the Massachusetts Institute of Technology:
the Joint Program on Science and Policy of Global Changes, and the Energy
Choices for a Greenhouse Constrained World.  Mobil also supports the
Battelle Northwest Study:  A Global Energy Technology Strategy to Address
Climate Change.  These are independent groups that share our desire to find
some common-sense answers to the questions asked in the climate change
debate.

      Contrary to the assertions in this resolution, Mobil is taking
"concrete steps" to assess opportunities for reducing greenhouse gases from
its operations.  While we seek to learn more about the science of climate
change, Mobil remains committed to research and development efforts that
assess technologies that reduce emissions of greenhouse gases.  In addition
to tracking emissions from Mobil facilities, we are implementing projects
to reduce flaring and venting in our operations in the North Sea and
offshore Nigeria.  Mobil is also supporting projects to counter emissions
through initiatives such as our reforestation projects with American
Forest.  Mobil's joint venture with Ford Motor Company, called "Let's Drive
for a Better Future," will develop new energy-efficient fuel and power-
train technologies as well as assess opportunities involving direct-
injection diesel, hydrocarbon processors for fuel-cell systems, and
alternative fuels.  These efforts will result in significant contributions
toward the efficient and low emissions use of Mobil products.

      Mobil also participates in the International Energy Agency's
Greenhouse Gas Research and Development Program, which includes technology
assessment, and research and development target-setting for the oil and
petrochemical industry.  Mobil has installed energy saving technologies at
refineries, undertaken energy management audits and worked to reduce gas
flaring in our offshore producing fields.  Mobil participates in government
programs to promote energy efficiency in office buildings and has been
recognized by the U.S.  EPA for a host of awards.  In addition, use of
Mobil's industry-leading synthetic lubricants has measurable energy
efficiency benefits in many applications.

Chapter Five - Other Mobil Annual Meeting Proposals


      Mobil has cut its carbon emissions by more than one million metric
tons in the past three years.  In addition to being effective, our
emissions reduction programs are economically logical and justified.

      With its continued support for scientific research, Mobil is taking a
leadership role in the effort to achieve an understanding of how man-made
emissions affect climate.  Mobil believes that while such an understanding
is being pursued, reasonable companies should take actions to reduce
greenhouse emissions within the framework of good economic sense.  Mobil is
doing just that.

      For the foregoing reasons, the Mobil Board recommends you vote
AGAINST the adoption of the proposal.

                              THE MOBIL BOARD

Directors' Meetings

            During 1998, the Mobil Board met 11 times and all current
      directors attended more than 75 percent of the meetings of the Mobil
      Board and their respective Board committees.

Directors' Compensation

            Mobil employees receive no extra pay for serving on the Mobil
      Board or its committees.  Each non-employee director receives an
      annual retainer comprised of $36,000 and 600 shares of Mobil common
      stock in the form of deferred common share equivalents.  Non-employee
      directors also receive a fee of $1,250 for each Board meeting and
      committee meeting attended, plus travel allowances where appropriate.
      Directors who chair committees receive additional annual fees of
      $8,000.  Non-employee directors may not participate in Mobil's
      incentive compensation or other employee benefit programs.  However,
      Mobil provides $100,000 of non-contributory group life insurance and
      $500,000 of accidental death insurance for accidents occurring while
      on Mobil business.

            Under the deferred fee plan, non-employee directors may defer,
      until retirement, receipt of all or a part of their fees and the cash
      portion of their annual retainers.  Deferred amounts may either be
      credited with notional interest or be represented by common share
      equivalents which earn notional dividends equal to dividends declared
      on Mobil common stock.  Notional interest on deferred cash accounts
      is credited at the average rate for 10-year U.S.  Treasury bonds over
      a six-month period, plus 1%, currently 6.08% per year.

Committees of the Mobil Board

            The Mobil Board appoints standing committees to help carry out
      its duties.  The functions and current membership of the five
      standing committees established by the Mobil Board are described
      below.  Each committee meets regularly during the year and promptly
      following each meeting advises the full Board of its actions and
      recommendations.  Each committee is composed entirely of non-employee
      directors.

            The Audit Committee, established in 1969, reviews with the
      independent auditors and Mobil's General Auditor the general scope of
      their respective audit coverages.  Such reviews include consideration
      of Mobil's accounting practices, procedures and system of internal
      accounting controls and any significant problems encountered.  The
      committee also recommends to the Board the appointment of Mobil's
      principal independent auditors.

            At least annually, the committee reviews the services performed
      and the fees charged by Mobil's independent auditors and determines
      that the non-audit services rendered by the independent auditors do
      not compromise their independence.

            The independent auditors and Mobil's General Auditor have
      direct access to the committee and may discuss with it any matters
      which may arise in connection with audits, the maintenance of
      internal accounting controls or any other matters relating to Mobil's
      financial affairs.  Furthermore, the committee may authorize the
      independent auditors to investigate any matters which the committee
      deems appropriate and may present its recommendations and conclusions
      to the Board.

            Iain D. T. Vallance

            Meetings last year: four.

            The Committee on Directors and Board Affairs, established in
      1977, reviews and makes recommendations to the Board regarding:
      corporate governance matters, including effectiveness of the Board,
      its committees and individual directors; procedures of the Board and
      its committees; and the composition, duties and responsibilities of
      the committees.  The committee also reviews and makes recommendations
      to the Board regarding compensation and meeting fees of non-employee
      directors.

            In addition, the committee proposes to the Board a slate of
      directors for election by the shareholders at the annual meeting and
      identifies and proposes to the Board candidates to fill Board
      vacancies.  The committee considers suggestions from many sources,
      including shareholders, regarding possible candidates for director.

            The committee will consider your suggestions for possible
      director candidates if you follow the procedure described below:

            You should send your nomination(s) to the Secretary of the
      Committee on Directors and Board Affairs, Mobil Corporation, 3225
      Gallows Road, Fairfax, Virginia 22037-0001.  Your nomination(s)
      should describe the qualifications of the candidate and should be
      accompanied by a written statement that the candidate is willing to
      serve and is committed to representing the interests of all the
      shareholders.  Candidates must be endorsed by a member of the
      Committee on Directors and Board Affairs or be supported by the
      holders of not less than 200 shares of common stock.  This number is
      subject to periodic review by the Committee on Directors and Board
      Affairs.

            You may also make your nomination(s) at an annual shareholders'
      meeting in the manner provided in the Mobil by-laws.  The Mobil by-
      laws require, among other things, that you provide written notice of
      your nomination(s) to Mobil at least 90 days before the anniversary
      date of the preceding annual meeting.  For a description of the full
      procedure governing these nominations, you should read the Mobil by-
      laws.  You may obtain a copy of the Mobil by-laws from the Secretary
      of Mobil.  At any meeting of shareholders, the presiding officer may
      refuse to acknowledge the nomination of any person not made in
      compliance with the procedure specified in the Mobil by-laws.

      The committee members are:

            Allen F. Jacobson (Chairman)
            Donald V. Fites
            Charles A. Heimbold, Jr.

                          EXECUTIVE COMPENSATION

Management Compensation and Organization Committee Report

            The Management Compensation and Organization Committee of the
      Mobil Board consists of directors who are neither employees nor
      officers of Mobil.  The committee regularly reviews Mobil's executive
      compensation policies and programs and determines the compensation of
      the senior executive officers.  Mobil's decisions on compensation of
      the chairman and chief executive officer and other employee directors
      are reviewed with and approved by all of the non-employee directors,
      who constitute a majority of the Board.

            The executive compensation program includes four elements
      which, in the committee's view, constitute a flexible and balanced
      method of establishing total compensation for senior management.  The
      four compensation elements, further discussed below, are base salary,
      short-term incentive awards, long-term incentive awards, and stock
      options.

            The committee's overall philosophy regarding the compensation
      of Mobil's executive officers is that these officers should receive
      total compensation that is equal to the average for comparable
      positions paid by the seven petroleum comparator or peer companies
      referred to in the following section when Mobil's performance is
      average compared to those companies; total compensation that is below
      the average for comparable positions when Mobil's comparative
      performance is below average; and total compensation that is above
      the average for comparable positions when Mobil's comparative
      performance is above average.

Base Salaries

            The committee annually reviews salary ranges for senior
      positions and approves adjustments necessary to align these ranges
      with the competitive rates of pay reported by seven major petroleum
      companies for similar positions.  These companies constitute Mobil's
      petroleum comparator group, and are named in the Performance Graph on
      page V-16, except that the salary data for the U.S. subsidiaries of
      British Petroleum Company p.l.c. and Royal Dutch Petroleum Company/
      "Shell" Transport and Trading Company p.l.c. are used because parent
      company data are not available.  The committee chose these seven
      companies as comparators because they are the major companies in
      direct competition with Mobil in most of its areas of business.

            The committee annually adopts guidelines for executive salary
      increases which are consistent with guidelines for all U.S. salaried
      employees.  These guidelines are generally based on the average
      salary increase budget within the comparator group.  Actual salaries
      within the established salary ranges are determined based on the
      individual executive's performance, position in the salary range and
      experience level.

            The committee's guidelines apply to annual periods beginning on
      July 1.  The guidelines adopted by the committee for the year
      beginning July 1, 1998 provided for base pay increases for employees
      whose salaries were below the competitive rate for their jobs, and
      lump sum payments instead of base pay increases for employees whose
      salaries were above the competitive rate for their jobs.  Mr. Noto's
      performance in 1998 was excellent.  Faced with deteriorating industry
      fundamentals and economic problems in some key markets, Mobil fared
      better than the average of the petroleum comparator group in several
      important performance measures, such as return on capital employed,
      earnings per share growth and total return to shareholders.  Benefits
      from expense reduction programs and other self-help initiatives
      offset significantly lower crude prices.  For this reason, and in
      view of the fact that Mr. Noto's salary is below the competitive
      rate for the job, the committee approved an increase in Mr. Noto's
      base salary to $980,000.

            Mr. Noto's salary continues to be below the average and median
      base salary paid for a comparable position by the companies in the
      petroleum comparator group.

Short-Term Incentive Program

            The goal of the short-term incentive program is to place a
      portion of executives' annual compensation at risk to encourage and
      reward sustained high performance each year.

            Under guidelines adopted by the committee for administering the
      1995 Mobil incentive compensation and stock ownership plan, under
      which short-term incentive awards for 1998 were made, a short-term
      incentive award target has been set for each eligible employee.  This
      target is the difference between the estimated total cash
      compensation (base salary plus short-term incentive award) for
      comparable positions at the petroleum comparator companies and the
      midpoint of the salary range for the employee's salary grade.  This
      target is then multiplied by a performance factor which, in the case
      of the chairman and chief executive officer and the other four
      executive officers identified in the Summary Compensation Table on
      page V-17, can range from 0 to 1.75 depending equally on Mobil's
      rankings in return on capital employed and earnings per share growth
      during the preceding year, in each case relative to that of the peer
      companies during the same year.

            Based on Mobil's performance during 1998, Mobil's ranking among
      its peers was third in return on capital employed and second in
      earnings per share growth, indicating an above average performance
      factor of 1.40.  Accordingly, the committee approved an award of
      $1,537,700 for Mr. Noto, which was the amount determined by
      multiplying Mr. Noto's incentive award target by the 1998
      performance factor.  The Committee notes that this award does not
      exceed the maximum award payable to Mr. Noto under the terms of the
      plan as approved by shareholders.

Long-Term Incentive Program

            The long-term incentive program links executive rewards to
      growth in long-term shareholder value.  The program is intended to
      focus executives' attention on Mobil's performance over a period of
      longer than one year.  The committee believes this program is a key
      tool in building value for Mobil shareholders, because it rewards the
      strategic decisions on capital investments which are necessary for
      success in the petroleum industry.  It is structured in four-year
      performance cycles during which achievement of longer-term financial,
      strategic and operational objectives is measured.

            The committee allots contingent stock equivalents, also known
      as performance shares, to key executives annually, at the beginning
      of each four-year performance cycle.  The committee allots a number
      of performance shares to each executive based on a dollar amount,
      calculated by multiplying the midpoint of the executive's salary
      grade by a percentage which varies with position level.  The
      committee then converts the amount determined in this manner into
      performance shares at the average market price of Mobil common stock
      over the 30 trading days immediately before the date of allotment.
      Over the four-year performance cycle, dividend equivalents are
      credited with respect to these allotments.  These dividend
      equivalents are immediately converted into additional performance
      shares.

            At the end of the four-year cycle, the committee determines the
      amount of the long-term award by multiplying the number of
      performance shares then-credited to an executive's account by (1) the
      average market price of Mobil common stock over the 30 trading days
      immediately before the end of the cycle and (2) a performance factor.
      The performance factor can range from between 0 and 150% depending on
      Mobil's performance over the cycle relative to its petroleum
      comparator group as measured by three criteria: return to
      shareholders (weighted 50%), earnings per share growth (weighted
      25%), and return on capital employed (weighted 25%).  The design of
      the plan provides for a performance factor of 100% when Mobil
      achieves average performance within the comparator group, with a
      higher or lower factor for higher than average or lower than average
      performance.

            For the 1995-1998 performance cycle, a special incentive was
      provided.  Prior to the start of the cycle, Mobil's chairman set
      three challenging goals for Mobil to achieve by the end of 1998:
      annual net income of $3.0 billion; annual return on capital employed
      of 12%; and a stock price of $125 prior to the two-for-one

Chapter Five - Other Mobil Annual Meeting Proposals


      stock split effective May 20, 1997. When the committee made the allotments
      of performance shares at the start of the 1995-1998 cycle, it determined
      that the awards otherwise payable at the end of the cycle would be
      increased by 5% if one of these goals was achieved by the end of 1998, 15%
      if two of these goals were achieved within that time or 30% if all three
      of these goals were achieved within that time.

            At the end of the 1995-1998 cycle, the committee compared
      Mobil's performance for the cycle with the performance of its
      petroleum comparator companies as measured by the three criteria
      described above.  Relative to the comparator group, Mobil's total
      return to shareholders ranked third, at 23.8%, its earnings per share
      growth ranked sixth, and its return on capital employed ranked
      fourth.  Taking all of these factors and their relative weightings
      into account, the committee determined that the performance factor
      for the cycle was 100%.

            Mr. Noto was allotted 23,320 performance shares at the start
      of the 1995-1998 cycle.  Based on the market price of Mobil common
      stock at the time of the allotment, $43.16 per share, the shares
      allotted to him had a nominal value at the time of grant equal to the
      midpoint of his salary group at Mobil at that time.  At the end of
      the 1995-1998 cycle, through the crediting of dividend equivalents to
      his account, there were 26,532 performance shares credited to his
      account.  The market price of Mobil common stock at the end of the
      cycle was $86.55.  Accordingly, applying the formula described above,
      his actual long-term incentive award was $2,296,234.  This reflected
      in part an increase in the price of Mobil common stock over the cycle
      of $43.39 per share.  In addition, because Mobil had, well before
      1998, achieved the three performance goals described above, each
      long-term incentive award otherwise payable was increased by 30%.  As
      a result, Mr. Noto's total award for the 1995-1998 cycle was
      $2,985,052.  Mr. Noto elected to defer 90% of this award and
      received 31,041 common share equivalents as a result of such
      deferral.

Stock Options

            Stock options are granted to emphasize the importance of
      increasing shareholder value over the long term, and to encourage and
      facilitate executives' personal ownership of Mobil stock.  The
      committee's policy is to grant options annually, at fair market
      value, to sustain executives' long-term perspective.  The committee
      has established stock ownership guidelines which provide a strong
      incentive for executives to strive for long-term results and to
      become significant Mobil shareholders.  These guidelines call for
      executives to own Mobil stock equal in value to a specified multiple
      of their respective annual salaries, with the multiple increasing
      with increases in executives' salary grades.  Executives moving to
      positions requiring higher levels of stock ownership are given five
      years to comply with these guidelines.

            The size of the stock option grant is related to the level of
      responsibility and individual performance of the executive and is
      intended, in conjunction with the long-term incentive program, to
      provide executives with the opportunity for total average long-term
      incentive compensation comparable to that afforded for similar
      positions by the petroleum comparator companies over time.  Because a
      number of Mobil's competitors have just one form of long-term
      compensation, generally stock options, the grant size is not targeted
      to the number of options granted by other companies.

            In 1998, the committee awarded Mr. Noto 200,000 stock
      options.  The committee believes the 1998 stock option grant
      level is competitively justified for the reasons described
      above.

Summary

            Each year, the Committee reviews the compensation program,
      giving particular attention to the program's linkage to increasing
      shareholder value while maintaining competitive total compensation within
      the petroleum comparator group. Since the competitive market for executive
      talent extends beyond the petroleum industry, the committee also makes
      cross checks each year against a broader comparator group. In 1997 and
      1998, an outside consultant reviewed for the committee the total
      compensation of the chairman and chief executive

      officer and other senior executives. This review was based on a survey of
      comparable positions at 18 other major corporations of similar size,
      complexity and quality from both the oil and other industries.

            The committee believes that the compensation program described
      above effectively links executive and shareholder interests and
      provides incentives that are consistent with the long-term strategies
      required for success in the petroleum industry.  Generally, a
      majority share of a senior executive's total compensation is
      structured in the form of incentives which reward the executive
      depending on corporate and individual performance.  Within the
      program's mix of performance-based incentives, an executive has an
      opportunity to earn above average total compensation for above
      average corporate and individual performance.

Executive Compensation Tax Deductibility

            U.S. income tax law limits the amount Mobil can deduct for
      compensation paid to named executive officers.  Performance-based
      compensation that meets IRS requirements is not subject to this limit.

            All awards made to the named executive officers under the 1995
      Mobil incentive compensation and stock ownership plan are designed to
      meet these requirements so that Mobil can deduct the related
      expenses.  Awards made under prior plans are deductible for Federal
      income tax purposes to the extent permitted by transitional rules
      provided by IRS regulations.

            The committee recognizes the possibility that at times, the
      amount of the base salary of a named executive officer, and other
      compensation not described in the preceding paragraph, may exceed the
      $1 million deduction limit allowed by the IRS and so may not be fully
      deductible for Federal income tax purposes.  The committee's policy
      is to make a determination at any such time whether to authorize the
      payment of these amounts without regard to deductibility or whether
      the terms of the payment should be modified so as to preserve any
      deduction otherwise available.

</TABLE>

- ---------------
(1) Number of shares covered by grants which may be exercised as stock
    options.  Options may be granted to employees as qualified stock options,
    which are defined as incentive stock options in the Internal Revenue Code,
    or options which are not qualified.  All options are granted at an option
    price equal to the fair market value of a share of Mobil common stock on
    the date of grant (but not less than the par value) for up to ten years
    after grant as determined by the Management Compensation and Organization
    Committee.  All options are 100% exercisable after three years.  Options
    are not transferable by the employee.  If the employee dies before
    exercising an option, it may be exercised on behalf of his or her estate
    or distributed to an heir or legatee.

(2) The figures shown are potential future undiscounted values and are
    unrelated to the grant date present values shown in the next column.

(3) Value based on modified Black-Scholes option pricing model which includes
    assumptions for variables such as interest rates, stock price volatility
    and future dividend yield.  Mobil's use of this model should not be
    construed as an endorsement of its accuracy.  Whether the model
    assumptions used will prove to be accurate cannot be known at the date
    of grant.  The Black-Scholes model produces a value based on freely
    tradeable securities.  Mobil employee stock options are not
    transferable, so the "present value" shown cannot be realized by the
    holder.  Recognizing the limitations of the model as described, the
    following assumptions were used to estimate the grant date present
    value: dividend yield of 3.20%, five-year zero-coupon risk-free
    interest rate of 5.66%, estimated volatility of 18% and estimated
    average expected option term of five years.  Mobil stock options are
    issued at the fair market value of its stock on the date of grant, and
    terminate if unexercised after ten years.  The holder can derive a
    benefit only to the extent the market value of Mobil common stock is
    higher than the exercise price at the date of the actual exercise.

(4) If the assumed annual rate of stock price appreciation of 0%, 5% or 10%
    per year should occur, the market value per share of Mobil common stock
    at the end of the ten-year option term would be $71.22, $116.01 or
    $184.72, as the case may be.

            Under this program, we determine allotments of contingent stock
      equivalents, also known as performance shares, for participants annually,
      at the start of a four-year performance period. We base these allotments
      on dollar amounts, determined by reference to the participants' level
      within Mobil and the midpoint of the participants' salary grade at the
      beginning of each period, which we then convert into performance shares at
      the average market price for Mobil common stock over the 30 trading days
      immediately preceding the allotment. Over the four-year cycle, we will
      credit dividend equivalents with respect to these allotments, which we
      will immediately convert into additional performance shares. After the end
      of the period, the Management

Chapter Five - Other Mobil Annual Meeting Proposals


      Compensation and Organization Committee of the Mobil Board determines the
      extent to which the contingent allotments should be converted into actual
      awards. The committee's policy in granting actual awards is based on
      Mobil's performance relative to its petroleum comparator group using three
      criteria: earnings per share growth, return on capital employed, and total
      shareholder return.

            Payouts under the program are based in part on the price of the
      Mobil common stock.  The price used for the estimates provided is
      $87.125 per share, which was the closing price of Mobil common stock
      on the New York Stock Exchange on December 31, 1998.  Actual payouts,
      if any, will be based on the mean of the high and low sales prices of
      Mobil common stock on the Exchange for a period of 30 trading days
      immediately before the determination of the committee referred to in
      the preceding paragraph.

Pension Table

            Mobil employees in the higher salary classifications receive
      pension benefits under two non-contributory plans: a retirement plan
      qualified under U.S. tax law, which is non-discriminatory, and a
      supplemental plan that provides benefits that cannot be provided
      under the qualified plan, due to the limitations imposed by U.S. tax
      law, plus certain additional benefits.  Employees who retire or
      terminate as vested participants are entitled to receive retirement
      benefits under these plans computed under a final average pay
      formula.  Benefits under the qualified plan are provided, at an
      employee's election, either in the form of a life annuity or in one
      of several alternative forms having an equivalent actuarial value.
      Benefits under the supplemental plan, which will constitute the
      majority of the benefits payable to Messrs.  Noto, Renna, DeLoach,
      Cramer and Pryor, are provided only in the form of an annuity for a
      fixed number of years equal to one-half the employee's life
      expectancy.  The table below shows the annual annuity amount that
      would be payable for life to employees in the higher salary
      classifications, commencing at age 60 or older, if they were to elect
      a life annuity under the qualified plan and if the benefits provided
      under the supplemental plan for one-half the employee's life
      expectancy were converted to a life annuity having an equivalent
      actuarial value.

Additional Retirement Compensation

            Under Mobil Oil Corporation's executive life insurance program,
      executives, including Mobil named executive officers, who retire
      after reaching age 55, or after age 50 with Mobil's consent, are
      entitled, in addition to term coverage to age 65, to a series of cash
      payments.  These payments commence once the executive attains age 65
      and continue for three to 15 years, according to the executive's
      advance election, and may be used to continue the policy or taken in
      cash.  The amounts of these payments are the amounts determined to be
      necessary, based on the insurance company's applicable mortality
      tables and an interest rate of 7.5%, to provide a fully paid up
      policy with a death benefit equal to two times the sum of the
      executive's final base pay and bonus.

       STOCK-BASED HOLDINGS OF DIRECTORS, NOMINEES AND EXECUTIVE OFFICERS

      The following table shows the shares of Mobil common stock, the shares
of such stock acquirable within 60 days pursuant to the exercise of employee
stock options, the units of interest in shares of Mobil's ESOP preferred
stock, the deferred common share equivalents, and the total Mobil stock-based
holdings, which are beneficially owned by each director and nominee for
director, each executive officer named in the Summary Compensation Table on
page V-17 who is not a director, and all directors and executive officers as a
group.  The table indicates the alignment of these individuals' personal
financial interests with the interests of Mobil's shareholders because the
value of their total holdings is dependent upon the price of Mobil common
stock.

</TABLE>


      The information in the table is as of March 1, 1999.  Shares of
Mobil common stock owned by directors and executive officers include 14,199
shares held by family members or family trusts of certain directors and
officers, as to which shares these persons disclaim beneficial ownership.
Shares of Mobil common stock owned by directors and executive officers also
include 62,000 shares of restricted stock held by certain officers as to which
shares these officers possess sole voting power, but no investment power,
during the restricted period.  The directors and executive officers have sole
discretion as to voting and investment power as to all remaining shares of
Mobil common stock which they presently hold.  Owners of units of  Mobil ESOP
preferred stock possess sole voting power, but no investment power, with
respect to these units.  Deferred common share equivalents are stock
equivalents equal in value to common stock which earn dividend equivalents
equal to dividends declared on common stock.  Executive officers are credited
with deferred common share equivalents under the supplemental employees
savings plan of Mobil Oil Corporation, and incentive awards to these officers
may be deferred and paid in equivalents under the 1995 Mobil incentive
compensation and stock ownership plan and its predecessors.  Non-employee
directors receive a portion of their annual retainers in equivalents
and may elect to receive all or part of their fees and the cash portion of
their annual retainers in equivalents under the deferred fee plan referred to on

                                      V-22

                           Chapter Five - Other Mobil Annual Meeting Proposals


page V-9.  In addition, when the retirement plan for non-employee directors
was terminated in January 1997, some directors elected to receive the
actuarial present values of their accrued benefits under that plan in such
equivalents.  Individuals credited with deferred common share equivalents do
not have voting power and may only exercise investment power in very limited
circumstances, in respect of these equivalents.

     No individual named above owns beneficially more than 1% of the outstanding
shares of either of Mobil's classes of voting securities, nor do all directors
and current executive officers as a group, including those named above.  As of
March 1, 1999, the trustee under the employees savings plan of Mobil Oil
Corporation held 28,015,387 shares of the common stock of Mobil in the plan,
which is approximately 3.59% of the total number of shares of Mobil common stock
outstanding at that date.  As of the same date, the trustee under the Mobil
ESOP, which is incorporated in the employees savings plan of Mobil Oil
Corporation, held all 163,469 outstanding shares of the Mobil ESOP preferred
stock.  The shares of common stock and preferred stock held by the trustees
together represented 5.57% of the votes which may be cast by the voting
securities of Mobil outstanding as of March 1, 1999.  All these shares of
common stock are beneficially owned by participants in the employees savings
plan of Mobil Oil Corporation; all these shares of Mobil ESOP preferred stock
which have been allocated to participants in the Mobil ESOP, numbering 90,260,
are beneficially owned by these participants, the balance being held for
allocation over the life of the plan.

Special Arrangements Relating to Possible Change of Control

           For a discussion of special arrangements affecting executive
     management which would result from a change of control, see "Interests
     of Certain Persons in the Merger" on page I-49.


                               OTHER MATTERS

Section 16(a) Beneficial Ownership Reporting Compliance

           Pursuant to Section 16(a) of the Securities and Exchange Act of
     1934, Mobil's directors and officers are required to file reports with
     the SEC and the NYSE, within specified monthly and annual due dates,
     relating to their ownership of and transactions in Mobil's equity
     securities.  Robert F. Amrhein, an officer of Mobil, inadvertently
     filed one monthly report relating to one transaction after the date by
     which it should have been filed.

                          FUTURE SHAREHOLDER PROPOSALS

Exxon

     Any shareholder proposal for Exxon's annual meeting in 2000 must be sent to

considered for inclusion in Exxon's proxy statement is December 11, 1999. The
deadline for notice of a proposal for which a shareholder will conduct his or
her own solicitation is February 23, 2000. On request, the Secretary will
provide detailed instructions for submitting proposals.

Mobil

     Mobil will hold an annual meeting in the year 2000 only if the merger has

will be eligible for consideration for inclusion in the proxy statement for the
2000 annual meeting pursuant to Rule 14a-8 under the Securities and Exchange Act
of 1934, as amended, if such proposals are received by Mobil before the close of

outside the processes of Rule 14a-8 will be considered timely, pursuant to the
advance notice requirement set forth in Article II, Section 1 of Mobil's
by-laws, if such notices are delivered to or mailed and received by Mobil during
the period beginning on February 25, 2000 and ending at the close of business on
March 27, 2000. Any such proposal or notice should be directed to the attention
of the Secretary, Mobil Corporation, 3225 Gallows Road, Fairfax, Virginia
22037-0001.

     SEC rules set forth standards for the exclusion of some shareholder
proposals from a proxy statement for an annual meeting.


                       WHERE YOU CAN FIND MORE INFORMATION

     Exxon and Mobil file annual, quarterly and special reports, proxy

the Exxon common stock to be issued to Mobil shareholders in the merger. This
joint proxy statement/prospectus is a part of that registration statement and
constitutes a prospectus of Exxon in addition to being a proxy statement of
Exxon and Mobil for the meetings. As allowed by SEC rules, this joint proxy
statement/prospectus does not contain all the information you can find in the
registration statement or the exhibits to the registration statement.

     The SEC allows us to "incorporate by reference" information into this joint
proxy statement/prospectus, which means that we can disclose important
information to you by referring you to another document filed separately with
the SEC. The information incorporated by reference is deemed to be part of this
joint proxy statement/prospectus, except for any information superseded by

                       AGREEMENT AND PLAN OF MERGER

     AGREEMENT AND PLAN OF MERGER dated as of December 1, 1998 among Mobil
Corporation, a Delaware corporation (the "Company"), Exxon Corporation, a New
Jersey corporation ("Acquiror"), and Lion Acquisition Subsidiary Corporation, a
newly-formed Delaware corporation and a wholly-owned first-tier subsidiary of
Acquiror ("Merger Subsidiary").

     WHEREAS, the respective Boards of Directors of Acquiror, Merger Subsidiary
and the Company have approved this Agreement, and deem it advisable and in the
best interests of their respective stockholders to consummate the merger of
Merger Subsidiary with and into the Company on the terms and conditions set
forth herein;

     WHEREAS, for United States federal income tax purposes, it is intended that
the Merger contemplated by this Agreement qualify as a "reorganization" within
the meaning of Section 368 of the Internal Revenue Code of 1986, as amended (the
"Code"), and the rules and regulations promulgated thereunder;

     WHEREAS, for accounting purposes, it is intended that the Merger be
accounted for as a pooling of interests under United States generally accepted
accounting principles ("GAAP"); and

     WHEREAS, as a condition and inducement to Acquiror entering into this
Agreement and incurring the obligations set forth herein, concurrently with the
execution and delivery of this Agreement, Acquiror and the Company are entering
into a Stock Option Agreement in the form of Exhibit A hereto (the "Option
Agreement") pursuant to which the Company has granted Acquiror an option,
exercisable under the circumstances specified therein, to purchase shares of
common stock, par value $1.00 per share, of the Company (the "Shares").

     NOW, THEREFORE, in consideration of the promises and the respective
representations, warranties, covenants, and agreements set forth herein, the
parties hereto agree as follows:


                                 ARTICLE 1
                                THE MERGER

     SECTION 1.01. The Merger. (a) At the Effective Time, Merger Subsidiary
shall be merged (the "Merger") with and into the Company in accordance with the
requirements of the General Corporation Law of the State of Delaware (the
"Delaware Law"), whereupon the separate existence of Merger Subsidiary shall
cease, and the Company shall be the surviving corporation in the Merger (the
"Surviving Corporation").

     (b) As soon as practicable after satisfaction or, to the extent permitted
hereunder, waiver of all conditions to the Merger, the Company and Merger
Subsidiary will file a certificate of merger with the Secretary of State of the
State of Delaware and make all other filings or recordings required by Delaware
Law in connection with the Merger. The Merger shall become effective at such
time as the certificate of merger is duly filed with the Secretary of State of
the State of Delaware or at such later time as is specified in the certificate
of merger (the "Effective Time").

     (c) From and after the Effective Time, the Surviving Corporation shall
possess all the rights, privileges, powers and franchises and be subject to all
of the restrictions, disabilities and duties of the Company and Merger
Subsidiary, all as provided under Delaware Law.

      (d) The closing of the Merger (the "Closing") shall take place (i) at the
offices of Davis Polk & Wardwell, 450 Lexington Avenue, New York, NY, as soon as
practicable, but in any event within three business days after the day on which
the last to be fulfilled or waived of the conditions set forth in Article 8
(other than those conditions that by their nature are to be fulfilled at the
Closing, but subject to the fulfillment or waiver of such conditions) shall be
fulfilled or waived in accordance with this Agreement or (ii) at such other
place and time or on such other date as the Company and Acquiror may agree
in writing (the "Closing Date").

Annex A -- Agreement and Plan of Merger


     SECTION 1.02.  Conversion of Shares.  (a)  At the Effective Time by
virtue of the Merger and without any action on the part of the holder
thereof:

          (i) each Share held by the Company as treasury stock or owned by
     Acquiror or any subsidiary of Acquiror (excluding Shares, if any, held in
     any "Rabbi trust" identified on Schedule 3.14, which may be accounted for
     as treasury stock ("Rabbi Trust Shares")) immediately prior to the
     Effective Time (together with the associated Company Right (as defined in
     Section 3.05), if any) shall be canceled, and no payment shall be made with
     respect thereto;

         (ii) each share of common stock of Merger Subsidiary outstanding
     immediately prior to the Effective Time shall be converted into and become
     one share of common stock of the Surviving Corporation with the same
     rights, powers and privileges as the shares so converted and shall
     constitute the only outstanding shares of capital stock of the Surviving
     Corporation;

        (iii) each Share (including each Rabbi Trust Share) (together with the
     associated Company Right) outstanding immediately prior to the Effective
     Time shall, except as otherwise provided in Section 1.02(a)(i), be
     converted into the right to receive 1.32015 (the "Exchange Ratio") shares
     of fully paid and nonassessable common stock, without par value, of
     Acquiror ("Acquiror Common Stock"); and

         (iv) Each issued and outstanding share of Series B ESOP Convertible
     Preferred Stock, par value $1.00 per share, of the Company (the "Series B
     Preferred Stock") held in the leveraged ESOP portion of the Company's
     Employee Savings Plan (the "Leveraged ESOP"), other than Dissenting Shares,
     shall be converted into the right to receive one validly issued, fully paid
     and nonassessable share of a new series of preferred stock to be issued by
     Acquiror (as a successor under Section 8(A) of the Certificate of
     Designation, Preferences and Rights establishing the Series B Preferred
     Stock) at the Effective Time (the "Acquiror Preferred Stock"). Each share
     of Acquiror Preferred Stock shall, to the extent possible, have terms that
     are identical to those of the Series B Preferred Stock immediately prior to
     the Effective Time, except that, (a) as a result of the Merger the issuer
     thereof shall be Acquiror rather than the Company, and (b) upon conversion
     thereof (at the same times and subject to the same terms and conditions
     under which Series B Preferred Stock is convertible into Shares) each share
     of Acquiror Preferred Stock shall be converted into that Merger
     Consideration (as defined below) which the holder thereof would have
     received had the Series B Preferred Stock of such holder been converted
     into Shares immediately prior to the Effective Time.

     (b) All Acquiror Common Stock issued as provided in this Section 1.02 shall
be of the same class and shall have the same terms as the currently outstanding
Acquiror Common Stock. Acquiror shall, following the Closing, except as provided
in Section 1.03(c), pay all stamp duties and stamp duty reserve tax, if any,
imposed in connection with the issuance or creation of the Acquiror Common Stock
and Acquiror Preferred Stock in connection with the Merger. The Company shall
have the right to approve the Certificate of Designations establishing the
Acquiror Preferred Stock, such approval not to be unreasonably withheld.

     (c) From and after the Effective Time, all Shares (together with the
associated Company Rights) converted in accordance with Section 1.02(a)(iii) and
all Series B Preferred Stock (other than Dissenting Shares) converted in
accordance with Section 1.02(a)(iv) shall no longer be outstanding and shall
automatically be canceled and retired and shall cease to exist, and each holder
of a certificate representing any such Shares or Series B Preferred Stock shall
cease to have any rights with respect thereto, except the right to receive the
Merger Consideration or Preferred Merger Consideration (each as defined below),
as applicable, and any dividends payable pursuant to Section 1.03(f). From and
after the Effective Time, all certificates representing the common stock of
Merger Subsidiary shall be deemed for all purposes to represent the number of
shares of common stock of the Surviving Corporation into which they were
converted in accordance with Section 1.02(a)(ii).

                                    A-2
<PAGE>

                                       Annex A -- Agreement and Plan of Merger


     (d) The Acquiror Common Stock to be received as consideration pursuant to
the Merger by each holder of Shares (together with cash in lieu of fractional
shares of Acquiror Common Stock as specified below) is referred to herein as the
"Merger Consideration". The Acquiror Preferred Stock to be received as
consideration pursuant to the Merger by each holder of Series B Preferred Stock
is referred to herein as the "Preferred Merger Consideration."

     (e) For purposes of this Agreement, the word "Subsidiary" when used with
respect to any Person means any other Person, whether incorporated or
unincorporated, of which (i) more than fifty percent of the securities or other
ownership interests or (ii) securities or other interests having by their terms
ordinary voting power to elect more than fifty percent of the board of directors
or others performing similar functions with respect to such corporation or other
organization, is directly owned or controlled by such Person or by any one or
more of its Subsidiaries. For purposes of this Agreement, "Person" means an
individual, a corporation, a limited liability company, a partnership, an
association, a trust or any other entity or organization, including a government
or political subdivision or any agency or instrumentality thereof.

     SECTION 1.03. Surrender and Payment. (a) Prior to the Effective Time,
Acquiror shall appoint an agent reasonably acceptable to the Company (the
"Exchange Agent") for the purpose of exchanging certificates representing Shares
or Series B Preferred Stock (the "Certificates") for the Merger Consideration or
Preferred Merger Consideration, as applicable. Acquiror will make available to
the Exchange Agent, as needed, the Merger Consideration and Preferred Merger
Consideration to be paid in respect of the Shares and the Series B Preferred
Stock, respectively. Promptly after the Effective Time, Acquiror will send, or
will cause the Exchange Agent to send, to each holder of record at the Effective
Time of Shares and Series B Preferred Stock a letter of transmittal for use in
such exchange (which shall specify that the delivery shall be effected, and risk
of loss and title shall pass, only upon proper delivery of the Certificates to
the Exchange Agent) in such form as the Company and Acquiror may reasonably
agree, for use in effecting delivery of Shares and Series B Preferred Stock to
the Exchange Agent.

     (b) Each holder of Shares that have been converted into a right to receive
the Merger Consideration, upon surrender to the Exchange Agent of a Certificate,
together with a properly completed letter of transmittal, will be entitled to
receive the Merger Consideration in respect of the Shares represented by such
Certificate. Until so surrendered, each such Certificate shall, after the
Effective Time, represent for all purposes only the right to receive such Merger
Consideration. Each holder of Series B Preferred Stock that has been converted
into a right to receive the Preferred Merger Consideration, upon surrender to
the Exchange Agent of a Certificate, together with a properly completed letter
of transmittal, will be entitled to receive the Preferred Merger Consideration
in respect of the Series B Preferred Stock represented by such Certificate.
Until so surrendered, each such Certificate shall, after the Effective Time,
represent for all purposes only the right to receive such Preferred Merger
Consideration.

     (c) If any portion of the Merger Consideration or the Preferred Merger
Consideration is to be paid to a Person other than the Person in whose name the
Certificate is registered, it shall be a condition to such payment that the
Certificate so surrendered shall be properly endorsed or otherwise be in proper
form for transfer and that the Person requesting such payment shall pay to the
Exchange Agent any transfer or other taxes required as a result of such payment
to a Person other than the registered holder of such Certificate or establish to
the satisfaction of the Exchange Agent that such tax has been paid or is not
payable.

     (d) After the Effective Time, there shall be no further registration of
transfers of Shares or Series B Preferred Stock. If, after the Effective Time,
Certificates are presented to the Surviving Corporation, they shall be canceled
and exchanged for the consideration provided for, and in accordance with the
procedures set forth, in this Article 1.

     (e) Any portion of the Merger Consideration or the Preferred Merger
Consideration made available to the Exchange Agent pursuant to Section 1.03(a)
that remains unclaimed by the holders of Shares or Series B Preferred Stock one
year after the Effective Time shall be returned to Acquiror, upon demand, and
any such holder who has not

                                    A-3

<PAGE>

Annex A -- Agreement and Plan of Merger


exchanged his Shares for the Merger Consideration or the Series B Preferred
Stock for the Preferred Merger Consideration, as applicable, in accordance
with this Section prior to that time shall thereafter look only to Acquiror
for payment of the Merger Consideration in respect of his Shares or the
Preferred Merger Consideration in respect of the Series B Preferred Stock.
Notwithstanding the foregoing, Acquiror shall not be liable to any holder
of Shares or Series B Preferred Stock for any amount paid to a public
official pursuant to applicable abandoned property laws.  Any amounts
remaining unclaimed by holders of Shares or Series B Preferred Stock three
years after the Effective Time (or such earlier date immediately prior to
such time as such amounts would otherwise escheat to or become property of
any governmental entity) shall, to the extent permitted by applicable law,
become the property of Acquiror free and clear of any claims or interest of
any Person previously entitled thereto.

     (f) No dividends or other distributions with respect to Acquiror Common
Stock or Acquiror Preferred Stock issued in the Merger shall be paid to the
holder of any unsurrendered Certificates until such Certificates are surrendered
as provided in this Section. Subject to the effect of applicable laws, following
such surrender, there shall be paid, without interest, to the record holder of
the Acquiror Common Stock or Acquiror Preferred Stock, as appropriate, issued in
exchange therefor (i) at the time of such surrender, all dividends and other
distributions payable in respect of such Acquiror Common Stock or Acquiror
Preferred Stock, as the case may be, with a record date after the Effective Time
and a payment date on or prior to the date of such surrender and not previously
paid and (ii) at the appropriate payment date, the dividends or other
distributions payable with respect to such Acquiror Common Stock or Acquiror
Preferred Stock, as the case may be, with a record date after the Effective Time
but with a payment date subsequent to such surrender. For purposes of dividends
or other distributions in respect of Acquiror Common Stock and Acquiror
Preferred Stock, all Acquiror Common Stock and Acquiror Preferred Stock to be
issued pursuant to the Merger (but not options therefor issued pursuant to
Section 1.04 unless actually exercised at the Effective Time) shall be entitled
to dividends pursuant to the immediately preceding sentence as if issued and
outstanding as of the Effective Time.

     SECTION 1.04. Stock Options. (a) At the Effective Time, each outstanding
option to purchase Shares (a "Company Stock Option") granted under the Company's
plans identified in Schedule 1.04 as being the only compensation or benefit
plans or agreements pursuant to which Shares may be issued (collectively, the
"Company Stock Option Plans"), whether vested or not vested, shall be deemed
assumed by Acquiror and shall thereafter be deemed to constitute an option to
acquire, on the same terms and conditions as were applicable under such Company
Stock Option prior to the Effective Time (in accordance with the past practice
of the Company with respect to interpretation and application of such terms and
conditions), the number (rounded down to the nearest whole number) of shares of
Acquiror Common Stock determined by multiplying (x) the number of Shares subject
to such Company Stock Option immediately prior to the Effective Time by (y) the
Exchange Ratio, at a price per share of Acquiror Common Stock (rounded up to the
nearest whole cent) equal to (A) the exercise price per Share otherwise
purchasable pursuant to such Company Stock Option divided by (B) the Exchange
Ratio. In addition, prior to the Effective Time, the Company will make any
amendments to the terms of such stock option or compensation plans or
arrangements that are necessary to give effect to the transactions contemplated
by this Section. The Company represents that no consents are necessary to give
effect to the transactions contemplated by this Section.

     (b) Acquiror shall take all corporate action necessary to reserve for
issuance a sufficient number of shares of Acquiror Common Stock and Acquiror
Preferred Stock for delivery pursuant to the terms set forth in this Section
1.04.

     (c) At the Effective Time, each award or account (including restricted
stock, stock equivalents and stock units, but excluding Company Stock Options)
outstanding as of the date hereof ("Company Award") that has been established,
made or granted under any employee incentive or benefit plans, programs or
arrangements and non-employee director plans maintained by the Company on
or prior to the date hereof which provide for grants of equity-based awards
or equity-based accounts shall be amended or converted into a similar
instrument of Acquiror, in each case with such adjustments to the terms and
conditions of such Company Awards as are appropriate to preserve the value
inherent in such Company Awards with no detrimental effects on the holders
thereof.  The other terms and conditions of each Company Award, and the
plans or agreements under which they were issued, shall continue to apply

                                    A-4
<PAGE>

                                       Annex A -- Agreement and Plan of Merger


in accordance with their terms and conditions, including any provisions for
acceleration (as such terms and conditions have been interpreted and
applied by the Company in accordance with its past practice).  The Company
represents that (i) there are no Company Awards or Company Stock Options
other than those reflected in Section 3.05 and (ii) all employee incentive
or benefit plans, programs or arrangements and non-employee director plans
under which any Company Award has been established, made or granted and all
Company Stock Option Plans are disclosed in Schedule 1.04.

     (d) At the Effective Time, Acquiror shall file with the Securities and
Exchange Commission (the "SEC") a registration statement on an appropriate form
or a post-effective amendment to a previously filed registration statement under
the Securities Act of 1933, as amended (the "1933 Act"), with respect to the
Acquiror Common Stock subject to options and other equity-based awards issued
pursuant to this Section 1.04, and shall use its reasonable best efforts to
maintain the current status of the prospectus contained therein, as well as
comply with any applicable state securities or "blue sky" laws, for so long as
such options or other equity-based awards remain outstanding.

     SECTION 1.05. Adjustments. If at any time during the period between the
date of this Agreement and the Effective Time, any change in the outstanding
shares of capital stock of Acquiror or the Company (other than as contemplated
in Section 3.05 or Section 4.05 or permitted under this Agreement) shall occur,
including, without limitation, by reason of any reclassification,
recapitalization, stock split or combination, exchange or readjustment of
shares, or any stock dividend thereon with a record date during such period, the
Merger Consideration and Preferred Merger Consideration shall be appropriately
adjusted.

     SECTION 1.06. Fractional Shares. (a) No fractional shares of Acquiror
Common Stock shall be issued in the Merger, but in lieu thereof each holder of
Shares otherwise entitled to a fractional share of Acquiror Common Stock will be
entitled to receive, from the Exchange Agent in accordance with the provisions
of this Section 1.06, a cash payment in lieu of such fractional shares of
Acquiror Common Stock representing such holder's proportionate interest, if any,
in the proceeds from the sale by the Exchange Agent in one or more transactions
of the number of shares of Acquiror Common Stock delivered to the Exchange Agent
by Acquiror pursuant to Section 1.03(a) over the aggregate number of whole
shares of Acquiror Common Stock to be distributed to the holders of the
certificates representing Shares pursuant to Section 1.03(b) (such excess being
herein called the "Excess Shares"). The parties acknowledge that payment of the
cash consideration in lieu of issuing fractional shares was not separately
bargained for consideration but merely represents a mechanical rounding off for
purposes of simplifying the corporate and accounting problems that would
otherwise be caused by the issuance of fractional shares. As soon as practicable
after the Effective Time, the Exchange Agent, as agent for the holders of the
certificates representing Shares, shall sell the Excess Shares at then
prevailing prices on the New York Stock Exchange (the "NYSE") in the manner
provided in the following paragraph.

     (b) The sale of the Excess Shares by the Exchange Agent, as agent for the
holders that would otherwise receive fractional shares, shall be executed on the
NYSE through one or more member firms of the NYSE and shall be executed in round
lots to the extent practicable. The compensation payable to the Exchange Agent
and the expenses incurred by the Exchange Agent, in each case, in connection
with such sale or sales of the Excess Shares, and all related commissions,
transfer taxes and other out-of-pocket transaction costs, will be paid by the
Surviving Corporation out of its own funds and will not be paid directly or
indirectly by Acquiror. Until the proceeds of such sale or sales have been
distributed to the holders of Shares, the Exchange Agent shall hold such
proceeds in trust for the holders of Shares (the "Common Shares Trust"). The
Exchange Agent shall determine the portion of the Common Shares Trust to which
each holder of Shares shall be entitled, if any, by multiplying the amount of
the aggregate proceeds comprising the Common Shares Trust by a fraction,
the numerator of which is the amount of the fractional share interest to
which such holder of Shares would otherwise be entitled and the denominator
of which is the aggregate amount of fractional share interests to which all
holders of Shares would otherwise be entitled.

                                    A-5
<PAGE>

Annex A -- Agreement and Plan of Merger


     (c) As soon as practicable after the determination of the amount of cash,
if any, to be paid to holders of Shares in lieu of any fractional shares of
Acquiror Common Stock, the Exchange Agent shall make available such amounts to
such holders of Shares without interest.

     SECTION 1.07. Withholding Rights. Each of the Surviving Corporation and
Acquiror shall be entitled to deduct and withhold from the consideration
otherwise payable to any person pursuant to this Article such amounts as it is
required to deduct and withhold with respect to the making of such payment under
any provision of federal, state, local or foreign tax law. To the extent that
amounts are so withheld by the Surviving Corporation or Acquiror, as the case
may be, such withheld amounts shall be treated for all purposes of this
Agreement as having been paid to the holder of the Shares in respect of which
such deduction and withholding was made by the Surviving Corporation or
Acquiror, as the case may be.

     SECTION 1.08. Lost Certificates. If any Certificate shall have been lost,
stolen or destroyed, upon the making of an affidavit of that fact by the person
claiming such Certificate to be lost, stolen or destroyed and, if required by
the Surviving Corporation, the posting by such person of a bond, in such
reasonable amount as the Surviving Corporation may direct, as indemnity against
any claim that may be made against it with respect to such Certificate, the
Exchange Agent will issue in exchange for such lost, stolen or destroyed
Certificate the Merger Consideration or Preferred Merger Consideration to be
paid in respect of the Shares or Series B Preferred Stock, as applicable,
represented by such Certificates as contemplated by this Article.

     SECTION 1.09. Shares Held by Company Affiliates. Anything to the contrary
herein notwithstanding, any shares of Acquiror Common Stock (or certificates
therefor) issued to affiliates of the Company pursuant to Section 1.03 shall be
subject to the restrictions described in Exhibit B-1 and Exhibit B-3, and such
shares (or certificates therefor) shall bear a legend describing such
restrictions.

     SECTION 1.10. Dissenter's Rights. Notwithstanding anything in this
Agreement to the contrary, any shares of Series B Preferred Stock outstanding
immediately prior to the Effective Time and held by a holder who has not voted
in favor of the Merger or consented thereto in writing and who has delivered a
written demand for appraisal of such shares in accordance with Section 262 of
the Delaware Law, if such Section 262 provides for appraisal rights for such
shares in the Merger ("Dissenting Shares"), shall not be converted into the
right to receive the Preferred Merger Consideration, unless and until such
holder fails to perfect or effectively withdraws or otherwise loses his right to
appraisal and payment under the Delaware Law. If, after the Effective Time, any
such holder fails to perfect or effectively withdraws or loses his right to
appraisal, such Dissenting Shares shall thereupon be treated as if they had been
converted as of the Effective Time into the right to receive the Preferred
Merger Consideration to which such holder is entitled, without interest or
dividends thereon. Any amounts paid to holders of Dissenting Shares in an
appraisal proceeding will be paid by the Surviving Corporation out of its own
funds and will not be paid, directly or indirectly, by Acquiror.

                        CERTAIN GOVERNANCE MATTERS

      SECTION 2.01. Acquiror Name. Acquiror shall take all such action as is

Effective Time, which action shall include, without limitation, seeking
stockholder approval to amend Acquiror's certificate of incorporation as
provided in Section 6.04.

      SECTION 2.02. Acquiror Board of Directors. (a) At the Effective Time,
Acquiror shall cause the Board of Directors of Acquiror to consist of not more

the Effective Time and six of whom shall be directors designated prior to the
Effective Time by the Company

officers of the Company and four shall be Persons who immediately prior to
the Effective Time were directors but not executive officers of the
Company)  (the "Company Board Designees").  Prior to the Effective Time,

Acquiror to not more than 19 and to elect the Company Board Designees to
the Board of Directors of Acquiror, in each case as of the Effective Time.

cause Mr. Lucio A. Noto to be elected as Vice Chairman of the Board of Directors

     (d) If the Effective Time occurs on a date which is less than nine months
before the next regularly scheduled annual meeting of stockholders of Acquiror,
Acquiror further agrees to use all reasonable efforts necessary to (i) nominate
the Company Board Designees for election as directors, (ii) elect Mr. Lucio A.
Noto as Vice Chairman of the Board of Directors of Acquiror, and (iii) cause at
least one Company Board Designee to be on each of the Audit Committee and
Compensation Committee of the Board of Directors of Acquiror, in each case in
connection with and as of such next regularly scheduled annual meeting.

      SECTION 2.03. Transition Committee. The parties agree to establish a
Transition Committee which will have a consultative role and which will be in
effect from the date hereof until the earlier of the termination hereof and the
Effective Time. The Transition Committee shall be comprised of Mr. Lee R.
Raymond and Mr. Lucio A. Noto. The Transition Committee will be concerned with
matters relating to planning the integration after the Effective Time of
Acquiror and the Company, including organization and staffing. The Transition
Committee will draw upon the resources of Acquiror and the Company as necessary
or appropriate.

      SECTION 2.04. Certificate of Incorporation of the Surviving Corporation.

the officers of the Surviving Corporation.


                                 ARTICLE 3
               REPRESENTATIONS AND WARRANTIES OF THE COMPANY

      The Company represents and warrants to Acquiror that:

     SECTION 3.01. Corporate Existence and Power. The Company is a corporation
duly incorporated, validly existing and in good standing under the laws of the
State of Delaware, and has all corporate powers and all governmental licenses,
authorizations, consents and approvals required to carry on its business as now
conducted, except for those the absence of which would not, individually or in
the aggregate, have a Material Adverse Effect on the Company. The

                                    A-7
<PAGE>

Annex A -- Agreement and Plan of Merger


Company is duly qualified to do business as a foreign corporation and is in
good standing in each jurisdiction where the character of the property
owned or leased by it or the nature of its activities makes such
qualification necessary, except for those jurisdictions where the failure
to be so qualified would not, individually or in the aggregate, have a
Material Adverse Effect on the Company.  For purposes of this Agreement, a
"Material Adverse Effect" with respect to any Person means a material
adverse effect on the financial condition, business, liabilities,
properties, assets or results of operations, taken as a whole, of such
Person and its Subsidiaries, taken as a whole, except to the extent
resulting from (w) any changes in general United States or global economic
conditions, (x) any changes affecting the oil and gas industry in general,
(y) matters whose significance or impact would reasonably be expected to be
primarily short term (i.e., under 18 months) or (z) matters disclosed on
Schedule 3.01.  The Company has heretofore delivered to Acquiror true and
complete copies of the Company's certificate of incorporation and by-laws
as currently in effect.

      SECTION 3.02. Corporate Authorization. (a) The execution, delivery and
performance by the Company of this Agreement and the Option Agreement and the
consummation by the Company of the transactions contemplated hereby and thereby
are within the Company's corporate powers and, except for any required approval
by the Company's stockholders in connection with the consummation of the Merger,
have been duly authorized by all necessary corporate action. The affirmative
vote of holders of the outstanding Shares and outstanding shares of Series B
Preferred Stock having votes representing a majority of the votes of all such
outstanding capital stock, voting together as a single class, is the only vote
of the holders of any of the Company's capital stock necessary in connection
with consummation of the Merger. Assuming due authorization, execution and
delivery of this Agreement and the Option Agreement by Acquiror and Merger
Subsidiary, as applicable, each of this Agreement and the Option Agreement
constitutes a valid and binding agreement of the Company enforceable against the
Company in accordance with its terms, subject to bankruptcy, insolvency,
fraudulent transfer, reorganization, moratorium and similar laws of general
applicability relating to or affecting creditors' rights and to general equity
principles.

     (b) The Company's Board of Directors, at a meeting duly called and held,
has (i) determined that this Agreement and the Option Agreement and the
transactions contemplated hereby and thereby (including the Merger) are fair to
and in the best interests of the Company's stockholders, (ii) approved and
adopted this Agreement and the Option Agreement and the transactions
contemplated hereby and thereby (including the Merger), and (iii) resolved
(subject to Section 5.02) to recommend approval and adoption of this Agreement
by its stockholders.

      SECTION 3.03. Governmental Authorization. The execution, delivery and
performance by the Company of this Agreement and the Option Agreement and the
consummation of the Merger by the Company require no action by or in respect of,
or filing with, any governmental body, agency, official or authority other than
(a) the filing of a certificate of merger in accordance with Delaware Law, (b)
compliance with any applicable requirements of the Hart-Scott-Rodino Antitrust
Improvements Act of 1976 (the "HSR Act"), (c) compliance with any applicable
requirements of Council Regulation No. 4064/89 of the European Community, as
amended (the "EC Merger Regulation"), (d) compliance with any applicable
requirements of Part IX of the Canadian Competition Act (the "Canadian Act"),
(e) compliance with any applicable requirements of the Securities Exchange Act
of 1934, as amended, and the rules and regulations promulgated thereunder (the
"Exchange Act"), (f) compliance with any applicable requirements of the
1933 Act and (g) other actions or filings which if not taken or made would
not, individually or in the aggregate, have a Material Adverse Effect on
the Company.

      SECTION 3.04. Non-Contravention. Except as set forth in Schedule 3.04, the
execution, delivery and performance by the Company of this Agreement and the
Option Agreement and the consummation by the Company of the transactions
contemplated hereby and thereby do not and will not (a) assuming compliance with
the matters referred to in Section 3.02, contravene or conflict with the
certificate of incorporation or by-laws of the Company, (b) assuming compliance
with the matters referred to in Section 3.03, contravene or conflict with or
constitute a violation of any provision of any law, regulation, judgment,
injunction, order or decree binding upon or applicable to the Company or any of
its Subsidiaries, (c) constitute a default under or give rise to a right of
termination, cancellation or acceleration of any right or obligation of the
Company or any of its Subsidiaries or to a loss of any benefit to which the
Company

                                    A-8
<PAGE>


                                       Annex A -- Agreement and Plan of Merger


or any of its Subsidiaries is entitled under any provision of any
agreement, contract or other instrument binding upon the Company or any of
its Subsidiaries or any license, franchise, permit or other similar
authorization held by the Company or any of its Subsidiaries, or (d) result
in the creation or imposition of any Lien on any asset of the Company or
any of its Subsidiaries, except for such contraventions, conflicts or
violations referred to in clause (b) or defaults, rights of termination,
cancellation or acceleration, or losses or Liens referred to in clause (c)
or (d) that would not, individually or in the aggregate, have a Material
Adverse Effect on the Company.  For purposes of this Agreement, "Lien"
means, with respect to any asset, any mortgage, lien, pledge, charge,
security interest or encumbrance of any kind in respect of such asset other
than any such mortgage, lien, pledge, charge, security interest or
encumbrance (i) for Taxes (as defined in Section 3.13) not yet due or being
contested in good faith (and for which adequate accruals or reserves have
been established on the Acquiror Balance Sheet or the Company Balance
Sheet, as the case may be) or (ii) which is a carriers', warehousemen's,
mechanics', materialmen's, repairmen's or other like lien arising in the
ordinary course of business.  Except as disclosed in Schedule 3.04, neither
the Company nor any Subsidiary of the Company is a party to any agreement
that expressly limits the ability of the Company or any Subsidiary of the
Company, or would limit Acquiror or any Subsidiary of Acquiror after the
Effective Time, to compete in or conduct any line of business or compete
with any Person or in any geographic area or during any period of time
except to the extent that any such limitation, individually or in the
aggregate, would not be reasonably likely to have a Material Adverse Effect
on Acquiror after the Effective Time.

      SECTION 3.05. Capitalization of the Company. The authorized capital stock
of the Company consists of 1,200,000,000 Shares and 30,000,000 shares of
preferred stock, par value $1.00 per share (of which 6,000,000 shares are
designated Series A Junior Participating Preferred Stock and 191,062 are
designated Series B Preferred Stock). As of the close of business on November
27, 1998, there were outstanding 779,934,096 Shares, no shares of Series A
Junior Participating Preferred Stock (all of which are reserved for issuance in
accordance with the Rights Agreement (the "Company Rights Agreement"), dated as
of December 15, 1995, between the Company and Mellon Bank, N.A., as Rights
Agent, pursuant to which the Company has issued rights ("Company Rights") to
purchase the Series A Junior Participating Preferred Stock) and 165,791.77
shares of Series B Preferred Stock, and employee stock options to purchase an
aggregate of 31,337,561 Shares (of which options to purchase an aggregate of
19,313,161 Shares were exercisable) and Company Awards (other than outstanding
restricted stock) with respect to an aggregate of 1,257,513.9444 Shares. All
outstanding shares of capital stock of the Company have been duly authorized and
validly issued and are fully paid and nonassessable. Except as set forth in this
Section and except for changes since the close of business on November 27, 1998
resulting from the exercise of employee stock options outstanding on such date
or options or stock-based awards granted as permitted by Section 5.01, there are
outstanding (a) no shares of capital stock or other voting securities of the
Company, (b) except for the Series B Preferred Stock, no securities of the
Company convertible into or exchangeable for shares of capital stock or voting
securities of the Company, and (c) except for the Series B Preferred Stock, and
except for the Option Agreement, no options, warrants or other rights to acquire
from the Company, and no preemptive or similar rights, subscription or other
rights, convertible securities, agreements, arrangements or commitments of any
character, relating to the capital stock of the Company, obligating the Company
to issue, transfer or sell, any capital stock, voting securities or securities
convertible into or exchangeable for capital stock or voting securities of
the Company or obligating the Company to grant, extend or enter into any
such option, warrant, subscription or other right, convertible security,
agreement, arrangement or commitment (the items in clauses 3.05(a), 3.05(b)
and 3.05(c) being referred to collectively as the "Company Securities").
Except for the Series B Preferred Stock, there are no outstanding
obligations of the Company or any of its Subsidiaries to repurchase, redeem
or otherwise acquire any Company Securities.

      SECTION 3.06. Subsidiaries. (a) Each Subsidiary of the Company is duly
organized, validly existing and in good standing under the laws of its
jurisdiction of organization, has all powers and all governmental licenses,
authorizations, consents and approvals required to carry on its business as now
conducted, except for those the absence of which would not, individually or in
the aggregate, reasonably be expected to have a Material Adverse Effect on the
Company. Each Subsidiary of the Company is duly qualified to do business and is
in good standing in each jurisdiction where the character of the property owned
or leased by it or the nature of its activities makes such qualification
necessary, except

                                    A-9
<PAGE>


Annex A -- Agreement and Plan of Merger


for those jurisdictions where failure to be so qualified would not,
individually or in the aggregate, have a Material Adverse Effect on the
Company.  All "significant subsidiaries", as such term is defined in
Section 1-02 of Regulation S-X under the Exchange Act (each, a "Significant
Subsidiary") of the Company and their respective jurisdictions of
incorporation are identified in the Company's annual report on Form 10-K
for the fiscal year ended December 31, 1997 (the "Company 10-K") or in
Schedule 3.06(a).

     (b) Except for directors' qualifying shares and except as set forth in the
Company 10-K, all of the outstanding capital stock of, or other ownership
interests in, each Significant Subsidiary of the Company is owned by the
Company, directly or indirectly, free and clear of any material Lien and free of
any other material limitation or restriction (including any restriction on the
right to vote, sell or otherwise dispose of such capital stock or other
ownership interests). There are no outstanding (i) securities of the Company or
any of its Subsidiaries convertible into or exchangeable for shares of capital
stock or other voting securities or ownership interests in any Significant
Subsidiary of the Company or (ii) options, warrants or other rights to acquire
from the Company or any of its Significant Subsidiaries, and no preemptive or
similar rights, subscription or other rights, convertible securities,
agreements, arrangements or commitments of any character, relating to the
capital stock of any Significant Subsidiary of the Company, obligating the
Company or any of its Significant Subsidiaries to issue, transfer or sell, any
capital stock, voting securities or other ownership interests in, or any
securities convertible into or exchangeable for any capital stock, voting
securities or ownership interests in, any Significant Subsidiary of the Company
or obligating the Company or any Significant Subsidiary of the Company to grant,
extend or enter into any such option, warrant, subscription or other right,
convertible security, agreement, arrangement or commitment except, in any such
case under clause (i) or (ii), to the extent relating to an insignificant equity
interest in any Significant Subsidiary (the items in clauses 3.06(b)(i) and
3.06(b)(ii) being referred to collectively as the "Company Subsidiary
Securities"). Except as set forth on Schedule 3.06(b), there are no outstanding
obligations of the Company or any of its Subsidiaries to repurchase, redeem or
otherwise acquire any outstanding Company Subsidiary Securities.

      SECTION 3.07. SEC Filings. (a) The Company has delivered to Acquiror (i)
its annual reports on Form 10-K for its fiscal years ended December 31, 1995,
1996 and 1997, (ii) its quarterly reports on Form 10-Q for its fiscal quarters
ended after December 31, 1997, (iii) its proxy or information statements
relating to meetings of, or actions taken without a meeting by, the stockholders
of the Company held since December 31, 1997, and (iv) all of its other reports,
statements, schedules and registration statements filed with the SEC since
December 31, 1997 (the documents referred to in this Section 3.07(a) being
referred to collectively as the "Company SEC Documents"). The Company's
quarterly report on Form 10-Q for its fiscal quarter ended September 30, 1998 is
referred to herein as the "Company 10-Q".

     (b) As of its filing date, each Company SEC Document complied as to form in
all material respects with the applicable requirements of the Exchange Act and
the 1933 Act.

     (c) As of its filing date, each Company SEC Document filed pursuant to the
Exchange Act did not contain any untrue statement of a material fact or omit to
state any material fact necessary in order to make the statements made therein,
in the light of the circumstances under which they were made, not misleading.

     (d) Each such registration statement, as amended or supplemented, if
applicable, filed pursuant to the 1933 Act as of the date such statement or
amendment became effective did not contain any untrue statement of a material
fact or omit to state any material fact required to be stated therein or
necessary to make the statements therein not misleading.

      SECTION 3.08. Financial Statements. The audited consolidated financial
statements and unaudited consolidated interim financial statements of the
Company (including any related notes and schedules) included in its annual
reports on Form 10-K and the quarterly reports on Form 10-Q referred to in
Section 3.07 fairly present in all material respects, in conformity with
generally accepted accounting principles applied on a consistent basis (except
as may be indicated in the notes thereto), the consolidated financial position
of the Company and its consolidated Subsidiaries as of the dates

thereof and their consolidated results of operations and changes in
financial position for the periods then ended (subject to normal year-end
adjustments and the absence of notes in the case of any unaudited interim
financial statements).  For purposes of this Agreement, "Company Balance
Sheet" means the consolidated balance sheet of the Company as of September
30, 1998 set forth in the Company 10-Q and "Company Balance Sheet Date"
means September 30, 1998.

      SECTION 3.09. Disclosure Documents. (a) Neither the proxy statement of the
Company (the "Company Proxy Statement") to be filed with the SEC in connection
with the Merger, nor any amendment or supplement thereto, will, at the date the
Company Proxy Statement or any such amendment or supplement is first mailed to
shareholders of the Company or at the time such shareholders vote on the
adoption and approval of this Agreement and the transactions contemplated
hereby, contain any untrue statement of a material fact or omit to state any
material fact necessary in order to make the statements therein, in light of the
circumstances under which they were made, not misleading. The Company Proxy
Statement will, when filed, comply as to form in all material respects with the
requirements of the Exchange Act. No representation or warranty is made by the
Company in this Section 3.09 with respect to statements made or incorporated by
reference therein based on information supplied by Acquiror or Merger Subsidiary
for inclusion or incorporation by reference in the Company Proxy Statement.

     (b) None of the information supplied or to be supplied by Company for
inclusion or incorporation by reference in the Acquiror Proxy Statement (as
defined in Section 4.09) or in the Form S-4 (as defined in Section 4.09) or any
amendment or supplement thereto will, at the time the Acquiror Proxy Statement
or any such supplement or amendment thereto is first mailed to the stockholders
of Acquiror or at the time such stockholders vote on the matters constituting
the Acquiror Stockholder Approval (as defined in Section 4.02) or at the time
the Form S-4 or any such amendment or supplement becomes effective under the
1933 Act or at the Effective Time, as the case may be, contain any untrue

Company nor any of its Subsidiaries is liable for any Tax imposed on any
entity other than such Person, except as the result of the application of
Treas.  Reg.  Section 1.1502-6 (and any comparable provision of the tax
laws of any state, local or foreign jurisdiction) to the affiliated group
of which the Company is the common parent.  For purposes of this Agreement,
"Taxes" shall mean any and all taxes, charges, fees, levies or other
assessments, including, without limitation, all net income, gross income,

      SECTION 3.14. Employee Benefit Plans. (a) Prior to the date hereof, the
Company has provided Acquiror with a list (set forth on Schedule 3.14)
identifying each material "employee benefit plan," as defined in Section 3(3) of
the Employee Retirement Income Security Act of 1974 ("ERISA"), each material
employment, severance or similar contract, plan, arrangement or policy
applicable to any director, former director, employee or former employee of the
Company and each material plan or arrangement (written or oral), providing for
compensation, bonuses, profit-sharing, stock option or other stock related
rights or other forms of incentive or deferred compensation, vacation benefits,
insurance coverage (including any self-insured arrangements), health or medical
benefits, disability benefits, workers' compensation, supplemental unemployment
benefits, severance benefits and post-employment or retirement benefits
(including compensation, pension, health, medical or life insurance benefits)
which is maintained, administered or contributed to by the Company and covers
any employee or director or former employee or director of the Company, or under
which the Company has any liability. Such material plans (excluding any such
plan that is a "multiemployer plan", as defined in Section 3(37) of ERISA) are
referred to collectively herein as the "Company Employee Plans".

     (b) Each Company Employee Plan has been maintained in compliance with its
terms and with the requirements prescribed by any and all statutes, orders,
rules and regulations (including but not limited to ERISA and the Code) which
are applicable to such Plan, except where failure to so comply would not,
individually or in the aggregate, have a Material Adverse Effect on the Company.

     (c) Neither the Company nor any affiliate of the Company has incurred a
liability under Title IV of ERISA that has not been satisfied in full, and no
condition exists that presents a material risk to the Company or any affiliate
of the Company of incurring any such liability other than liability for premiums
due the Pension Benefit Guaranty Corporation (which premiums have been paid when
due).

     (d) Each Company Employee Plan which is intended to be qualified under
Section 401(a) of the Code is so qualified and has been so qualified during the
period from its adoption to date, and each trust forming a part thereof is
exempt from federal income tax pursuant to Section 501(a) of the Code.

     (e) Except as set forth in Schedule 3.14, no director or officer or other
employee of the Company or any of its Subsidiaries will become entitled to any
retirement, severance or similar benefit or enhanced or accelerated benefit
(including any acceleration of vesting or lapse of repurchase rights or
obligations with respect to any employee stock option or other benefit under any
stock option plan or compensation plan or arrangement of the Company) solely as
a result of the transactions contemplated hereby.

     (f) Except as reflected in the Company SEC Documents filed prior to the
date hereof, no Company Employee Plan provides post-retirement health and
medical, life or other insurance benefits for retired employees of the Company
or any of its Subsidiaries.

Annex A -- Agreement and Plan of Merger


     (g) Except as set forth on Schedule 3.14, there has been no amendment to,
written interpretation or announcement (whether or not written) by the Company
or any of its affiliates relating to, or change in employee participation or
coverage under, any Company Employee Plan which would increase materially the
expense of maintaining such Company Employee Plan above the level of the expense
incurred in respect thereof for the 12 months ended on the Company Balance Sheet
Date.

      SECTION 3.15. Compliance with Laws. Neither the Company nor any of its
Subsidiaries is in violation of, or has since January 1, 1997 violated, any
applicable provisions of any laws, statutes, ordinances or regulations except
for any violations that, individually or in the aggregate, would not reasonably
be expected to have a Material Adverse Effect on the Company.

      SECTION 3.16. Finders' or Advisors' Fees. Except for Goldman, Sachs & Co.,
a copy of whose engagement agreement has been provided to Acquiror, there is no
investment banker, broker, finder or other intermediary which has been retained
by or is authorized to act on behalf of the Company or any of its Subsidiaries
who might be entitled to any fee or commission in connection with the
transactions contemplated by this Agreement.

      SECTION 3.17. Environmental Matters. (a) Except as set forth in the
Company SEC Documents filed prior to the date hereof and with such exceptions
as, individually or in the aggregate, have not had, and would not reasonably be
expected to have, a Material Adverse Effect on the Company, (i) no notice,
notification, demand, request for information, citation, summons, complaint or
order has been received by, and no investigation, action, claim, suit,
proceeding or review is pending or, to the knowledge of the Company or any of
its Subsidiaries, threatened by any Person against, the Company or any of its
Subsidiaries, and no penalty has been assessed against the Company or any of its
Subsidiaries, in each case, with respect to any matters relating to or arising
out of any Environmental Law; (ii) the Company and its Subsidiaries are and have
been in compliance with all Environmental Laws; (iii) there are no liabilities
of or relating to the Company or any of its Subsidiaries relating to or arising
out of any Environmental Law of any kind whatsoever, whether accrued,
contingent, absolute, determined, determinable or otherwise, and there is no
existing condition, situation or set of circumstances which could reasonably be
expected to result in such a liability; and (iv) there has been no environmental
investigation, study, audit, test, review or other analysis conducted of which
the Company has knowledge in relation to the current or prior business of the
Company or any of its Subsidiaries or any property or facility now or
previously owned, leased or operated by the Company or any of its
Subsidiaries which has not been delivered to Acquiror at least five days
prior to the date hereof.

     (b) For purposes of this Section 3.17 and Section 4.17, the term
"Environmental Laws" means any federal, state, local and foreign statutes, laws
(including, without limitation, common law), judicial decisions, regulations,
ordinances, rules, judgments, orders, codes, injunctions, permits, governmental
agreements or governmental restrictions relating to human health and safety, the
environment or to pollutants, contaminants, wastes, or chemicals.

      SECTION 3.18. Opinion of Financial Advisor. The Company has received the
opinion of Goldman, Sachs & Co. to the effect that, as of the date of such
opinion, the Exchange Ratio is fair from a financial point of view to the
holders of Shares (other than Acquiror or any of its Subsidiaries or
affiliates), and, as of the date hereof, such opinion has not been withdrawn.

      SECTION 3.19.  Pooling;  Tax Treatment.  (a)  The Company intends
that the Merger be accounted for under the "pooling of interests" method
under the requirements of Opinion No. 16 (Business Combinations) of the
Accounting Principles Board of the American Institute of Certified Public
Accountants, the Financial Accounting Standards Board, and the rules and
regulations of the SEC.

     (b)  Neither the Company nor any of its affiliates has taken or agreed
to take any action or is aware of any fact or circumstance that would
prevent the Merger from qualifying (i) for "pooling of interests"
accounting treatment as

                                   A-14
<PAGE>


                                       Annex A -- Agreement and Plan of Merger


described in (a) above or (ii) as a reorganization within the meaning of
Section 368 of the Code (a "368 Reorganization").

      SECTION 3.20. Pooling Letter. The Company has received a letter from Ernst
& Young LLP dated as of November 22, 1998 and addressed to the Company, a copy
of which has been delivered to Acquiror, in which Ernst & Young LLP concurs with
the Company management's conclusion that, as of November 22, 1998, no conditions
exist related to the Company that would preclude the Acquiror from accounting
for the Merger as a pooling of interests, and such letter has not been withdrawn
or modified in any material respect as of the date hereof.

      SECTION 3.21. Takeover Statutes. The Board of Directors of the Company has
taken the necessary action to make inapplicable the application of Section 203
of the Delaware Law, any other applicable antitakeover or similar statute or
regulation and the supermajority voting provisions of Article 6 of the Company's
certificate of incorporation to this Agreement and the Option Agreement and the
transactions contemplated hereby and thereby.

      SECTION 3.22. Rights Agreement. The Board of Directors of the Company has
resolved to, and the Company promptly after the execution hereof will, take all
action necessary to render the rights issued pursuant to the terms of the
Company Rights Agreement inapplicable to the Merger, this Agreement, the Option
Agreement and the other transactions contemplated hereby and thereby.


                                 ARTICLE 4
                REPRESENTATIONS AND WARRANTIES OF ACQUIROR

      Acquiror represents and warrants to the Company that:

      SECTION 4.01. Corporate Existence and Power. Each of Acquiror and Merger
Subsidiary is a corporation duly incorporated, validly existing and in good
standing under the laws of its jurisdiction of incorporation and has all
corporate powers and all governmental licenses, authorizations, consents and
approvals required to carry on its business as now conducted, except for
those the absence of which would not, individually or in the aggregate,
have a Material Adverse Effect on Acquiror.  Acquiror is duly qualified to
do business as a foreign corporation and is in good standing in each
jurisdiction where the character of the property owned or leased by it or
the nature of its activities makes such qualification necessary, except for
those jurisdictions where the failure to be so qualified would not,
individually or in the aggregate, have a Material Adverse Effect on
Acquiror.  Since the date of its incorporation, Merger Subsidiary has not
engaged in any activities other than in connection with or as contemplated
by this Agreement.  Acquiror has heretofore delivered to the Company true
and complete copies of Acquiror's and Merger Subsidiary's certificate of
incorporation and by-laws as currently in effect.

      SECTION 4.02. Corporate Authorization. (a) The execution, delivery and
performance by Acquiror and Merger Subsidiary of this Agreement, and by Acquiror
of the Option Agreement, and the consummation by Acquiror and Merger Subsidiary
of the transactions contemplated hereby and thereby are within the corporate
powers of Acquiror and Merger Subsidiary and have been duly authorized by all
necessary corporate action, except for any required approval by Acquiror's
stockholders of (i) the Merger, (ii) the amendment of Acquiror's certificate of
incorporation to increase the authorized shares of Acquiror Common Stock and to
change Acquiror's name in accordance with Section 2.01 and (iii) the issuance of
Acquiror Common Stock in connection with the Merger (clauses (i), (ii) and (iii)
being the "Acquiror Stockholder Approval") and except for the designation by the
Board of Directors of shares of the Acquiror's authorized preferred stock as
Acquiror Preferred Stock. The affirmative vote of the holders of shares of
Acquiror Common Stock and shares of Class A Preferred Stock having votes
representing a majority of the votes cast by all such shares, voting together as
a single class, is the only vote of the holders of any of Acquiror's capital
stock necessary in connection with obtaining the Acquiror Stockholder Approval.
Assuming due authorization, execution

                                   A-15

Annex A -- Agreement and Plan of Merger


and delivery of this Agreement and the Option Agreement by the Company,
this Agreement constitutes a valid and binding agreement of each of
Acquiror and Merger Subsidiary and the Option Agreement constitutes a valid
and binding agreement of Acquiror, in each case enforceable against such
party in accordance with its terms, subject to bankruptcy, insolvency,
fraudulent transfer, reorganization, moratorium and similar laws of general
applicability relating to or affecting creditors' rights and to general
equity principles.  The shares of Acquiror Common Stock and Acquiror
Preferred Stock issued pursuant to the Merger, when issued in accordance
with the terms hereof, will be duly authorized, validly issued, fully paid
and nonassessable and not subject to preemptive rights.

     (b) Acquiror's Board of Directors, at a meeting duly called and held, has
(i) approved this Agreement and the Option Agreement and the transactions
contemplated hereby and thereby (including the Merger), and (ii) resolved
(subject to Section 6.04) to recommend approval by its stockholders of the
matters constituting the Acquiror Stockholder Approval.

      SECTION 4.03. Governmental Authorization. The execution, delivery and
performance by Acquiror and Merger Subsidiary of this Agreement, and by Acquiror
of the Option Agreement, and the consummation by Acquiror and Merger Subsidiary
of the transactions contemplated hereby and thereby require no action by or in
respect of, or filing with, any governmental body, agency, official or authority
other than (a) the filing of a certificate of merger in accordance with Delaware
Law, (b) compliance with any applicable requirements of the HSR Act, (c)
compliance with any applicable requirements of the EC Merger Regulation, (d)
compliance with any applicable requirements of the Canadian Act, (e) compliance
with any applicable requirements of the Exchange Act, (f) compliance with any
applicable requirements of the 1933 Act and (g) other actions or filings which
if not taken or made would not, individually or in the aggregate, have a
Material Adverse Effect on Acquiror.

      SECTION 4.04. Non-Contravention. The execution, delivery and performance
by Acquiror and Merger Subsidiary of this Agreement, and by Acquiror of the
Option Agreement, and the consummation by Acquiror and Merger Subsidiary of the
transactions contemplated hereby and thereby do not and will not (a) assuming
compliance with the matters referred to in Section 4.02, contravene or conflict
with the certificate of incorporation or by-laws of Acquiror or Merger
Subsidiary, (b) assuming compliance with the matters referred to in Section
4.03, contravene or conflict with any provision of any law, regulation,
judgment, injunction, order or decree binding upon or applicable to
Acquiror or any of its Subsidiaries, (c) constitute a default under or give
rise to any right of termination, cancellation or acceleration of any right
or obligation of Acquiror or any of its Subsidiaries or to a loss of any
benefit to which Acquiror or any of its Subsidiaries is entitled under any
provision of any agreement, contract or other instrument binding upon
Acquiror or any of its Subsidiaries or any license, franchise, permit or
other similar authorization held by Acquiror or any of its Subsidiaries or
(d) result in the creation or imposition of any Lien on any asset of
Acquiror or any of its Subsidiaries, except for such contraventions,
conflicts or violations referred to in clause (b) or defaults, rights of
termination, cancellation or acceleration, or losses or Liens referred to
in clause (c) or (d) that would not, individually or in the aggregate, have
a Material Adverse Effect on Acquiror.  Neither Acquiror nor any Subsidiary
of Acquiror is a party to any agreement that expressly limits the ability
of Acquiror or any Subsidiary of Acquiror to compete in or conduct any line
of business or compete with any Person or in any geographic area or during
any period of time except to the extent that any such limitation,
individually or in the aggregate, would not be reasonably likely to have a
Material Adverse Effect on Acquiror after the Effective Time.

      SECTION 4.05. Capitalization. The authorized capital stock of Acquiror
consists of 3,000,000,000 shares of Acquiror Common Stock and 200,000,000 shares
of preferred stock, without par value (of which 16,500,000 are designated Class
A Preferred Stock and 100,000,000 are designated Class B Preferred Stock). As of
the close of business on November 27, 1998, there were outstanding 2,427,693,787
shares of Acquiror Common Stock, 1,884,638 shares of Class A Preferred Stock and
no shares of Class B Preferred Stock, and employee stock options to purchase an

exercisable). All outstanding shares of capital stock of Acquiror have been duly
authorized and validly issued and are fully paid and nonassessable. Except as
set forth in this Section

<PAGE>


                                       Annex A -- Agreement and Plan of Merger


and except for changes since the close of business on November 27, 1998
resulting from the exercise of employee stock options outstanding on such
date or options or other stock-based awards granted as permitted by Section
6.01 and except for the shares to be issued in connection with the Merger,
there are outstanding (a) no shares of capital stock or other voting
securities of Acquiror, (b) no securities of Acquiror convertible into or
exchangeable for shares of capital stock or voting securities of Acquiror,
and (c) no options, warrants or other rights to acquire from Acquiror, and
no preemptive or similar rights, subscription or other rights, convertible
securities, agreements, arrangements, or commitments of any character,
relating to the capital stock of Acquiror, obligating Acquiror to issue,
transfer or sell any capital stock, voting security or securities
convertible into or exchangeable for capital stock or voting securities of
Acquiror or obligating Acquiror to grant, extend or enter into any such
option, warrant, subscription or other right, convertible security,
agreement, arrangement or commitment (the items in clauses 4.05(a), 4.05(b)

There are no outstanding obligations of Acquiror or any of its Subsidiaries
to repurchase, redeem or otherwise acquire any Acquiror Securities.

      SECTION 4.06. Subsidiaries. (a) Each Subsidiary of Acquiror is duly
organized, validly existing and in good standing under the laws of its
jurisdiction of organization, has all powers and all governmental licenses,
authorizations, permits, consents and approvals required to carry on its
business as now conducted, except for those the absence of which would not,
individually or in the aggregate, reasonably be expected to have a Material
Adverse Effect on Acquiror. Each Subsidiary of Acquiror is duly qualified to do
business and is in good standing in each jurisdiction where the character of the
property owned or leased by it or the nature of its activities makes such
qualifications necessary, except for those jurisdictions where failure to be so
qualified would not, individually or in the aggregate, have a Material Adverse
Effect on Acquiror. All Significant Subsidiaries of Acquiror and their
respective jurisdictions of incorporation are identified in Acquiror's annual
report on Form 10-K for the fiscal year ended December 31, 1997 ("Acquiror
10-K").

     (b) Except for directors' qualifying shares and except as set forth in the
Acquiror 10-K, all of the outstanding capital stock of, or other ownership
interests in, each Significant Subsidiary of Acquiror is owned by Acquiror,
directly or indirectly, free and clear of any material Lien and free of any
other material limitation or restriction (including any restriction on the
right to vote, sell or otherwise dispose of such capital stock or other
ownership interests).  There are no outstanding (i) securities of Acquiror
or any of its Subsidiaries convertible into or exchangeable for shares of
capital stock or other voting securities or ownership interests in any
Significant Subsidiary of Acquiror, and (ii) options, warrants or other
rights to acquire from Acquiror or any of its Significant Subsidiaries, and
no preemptive or similar rights, subscriptions or other rights, convertible
securities, agreements, arrangements or commitments of any character,
relating to the capital stock of any Significant Subsidiary of Acquiror,
obligating Acquiror or any of its Significant Subsidiaries to issue,
transfer or sell, any capital stock, voting securities or other ownership
interests in, or any securities convertible into or exchangeable for any
capital stock, voting securities or ownership interests in, any Significant
Subsidiary of Acquiror or obligating Acquiror or any Significant Subsidiary
of Acquiror to grant, extend or enter into any such option, warrant,
subscription or other right, convertible security, agreement, arrangement
or commitment except, in any such case under clause (i) or (ii), to the
extent relating to an insignificant equity interest in any Significant
Subsidiary (items in clauses 4.06(b)(i) and 4.06(b)(ii) being referred to
collectively as the "Acquiror Subsidiary Securities").  There are no
outstanding obligations of Acquiror or any of its Subsidiaries to
repurchase, redeem or otherwise acquire any outstanding Acquiror Subsidiary
Securities.

      SECTION 4.07. SEC Filings. (a) Acquiror has delivered to the Company (i)
its annual reports on Form 10-K for its fiscal years ended December 31, 1995,

     (c) As of its filing date, each Acquiror SEC Document filed pursuant to the
Exchange Act did not contain any untrue statement of a material fact or omit to
state any material fact necessary in order to make the statements made therein,
in the light of the circumstances under which they were made, not misleading.

     (d) Each such registration statement as amended or supplemented, if
applicable, filed pursuant to the 1933 Act as of the date such statement or
amendment became effective did not contain any untrue statement of a material
fact or omit to state any material fact required to be stated therein or

consolidated Subsidiaries as of the dates thereof and their consolidated results
of operations and changes in financial position for the periods then ended

in the Merger, that may be required to be filed with the SEC in connection with
the issuance of shares of Acquiror Common Stock pursuant to the Merger and
any amendments or supplements thereto, will, when filed, subject to the
last sentence of Section 4.09(b), comply as to form in all material
respects with the applicable requirements of the 1933 Act.

     (b) Neither the Acquiror Proxy Statement nor any amendment or supplement
thereto, will, at the date the Acquiror Proxy Statement or any such amendment or
supplement is first mailed to shareholders of Acquiror or at the time such
shareholders vote on the matters constituting the Acquiror Stockholder Approval,
contain any untrue statement of a material fact or omit to state any material
fact necessary in order to make the statements therein, in light of the
circumstances under which they were made, not misleading. Neither the Form S-4
nor any amendment or supplement thereto will at the time it becomes effective
under the 1933 Act or at the Effective Time contain any untrue statement of a
material fact or omit to state a material fact required to be stated therein or
necessary to make the statements therein not misleading. No representation or
warranty is made by Acquiror in this Section 4.09 with respect to statements
made or incorporated by reference therein based on information supplied by the
Company for inclusion or incorporation by reference in the Acquiror Proxy
Statement or the Form S-4.

     (c) None of the information supplied or to be supplied by Acquiror for
inclusion or incorporation by reference in the Company Proxy Statement or any

status of Acquiror and its Subsidiaries (other than Taxes which are being
contested in good faith and for which adequate reserves are reflected on
the Acquiror Balance Sheet);  (iii)  Acquiror and its Subsidiaries have
made provision for all Taxes payable by Acquiror and its Subsidiaries for
which no Acquiror Tax Return has yet been filed;  (iv) the charges,
accruals and reserves for Taxes with respect to Acquiror and its

pending against or with respect to Acquiror or any of its Subsidiaries in

any entity other than such Person, except as the result of the application
of Treas.  Reg.  Section 1.1502-6 (and any comparable provision of the tax
laws of any state, local or foreign jurisdiction) to the affiliated group
of which Acquiror is the common parent.

      SECTION 4.14. Employee Benefit Plans. (a) Prior to the date hereof,
Acquiror has provided the Company with a list (set forth on Schedule 4.14)
identifying each material "employee benefit plan," as defined in Section 3(3) of
ERISA, each employment, severance or similar contract, plan, arrangement or
policy applicable to any director, former director, employee or former employee
of Acquiror and each material plan or arrangement (written or oral), providing
for compensation, bonuses, profit-sharing, stock option or other stock related
rights or other forms of incentive or deferred compensation, vacation benefits,
insurance coverage (including any self-insured arrangements), health or medical
benefits, disability benefits, workers' compensation, supplemental unemployment
benefits, severance benefits and post-employment or retirement benefits
(including compensation, pension, health, medical or life insurance benefits)
which is maintained, administered or contributed to by Acquiror and covers any
employee or director or former employee or director of Acquiror, or under which
Acquiror has any liability. Such material plans (excluding any such plan that is
a "multiemployer plan", as defined in Section 3(37) of ERISA) are referred to
collectively herein as the "Acquiror Employee Plans".

     (b) Each Acquiror Employee Plan has been maintained in compliance with its
terms and with the requirements prescribed by any and all statutes, orders,
rules and regulations (including but not limited to ERISA and the Code) which
are applicable to such Plan, except where failure to so comply would not,
individually or in the aggregate, have a Material Adverse Effect on Acquiror.

     (c) Neither Acquiror nor any affiliate of Acquiror has incurred a liability
under Title IV of ERISA that has not been satisfied in full, and no condition
exists that presents a material risk to Acquiror or any affiliate of Acquiror of
incurring any such liability other than liability for premiums due the Pension
Benefit Guaranty Corporation (which premiums have been paid when due).

     (d) Each Acquiror Employee Plan which is intended to be qualified under
Section 401(a) of the Code is so qualified and has been so qualified during the
period from its adoption to date, and each trust forming a part thereof is
exempt from federal income tax pursuant to Section 501(a) of the Code.

     (e) No director or officer or other employee of Acquiror or any of its
Subsidiaries will become entitled to any retirement, severance or similar
benefit or enhanced or accelerated benefit solely as a result of the
transactions contemplated hereby.

     (f) Except as reflected in the Acquiror SEC Documents filed prior to the
date hereof, no Acquiror Employee Plan provides post-retirement health and
medical, life or other insurance benefits for retired employees of Acquiror or
any of its Subsidiaries.

     (g) There has been no amendment to, written interpretation or announcement
(whether or not written) by Acquiror or any of its affiliates relating to, or
change in employee participation or coverage under, any Acquiror Employee Plan
which would increase materially the expense of maintaining such Acquiror
Employee Plan above the level of the expense incurred in respect thereof for the
12 months ended on the Acquiror Balance Sheet Date.

      SECTION 4.15. Compliance with Laws. Neither Acquiror nor any of its
Subsidiaries is in violation of, or has since January 1, 1997 violated, any
applicable provisions of any laws, statutes, ordinances or regulations except
for any violations that, individually or in the aggregate, would not reasonably
be expected to have a Material Adverse Effect on Acquiror.

      SECTION 4.16. Finders' or Advisors' Fees. Except for J.P. Morgan
Securities Inc., whose fees will be paid by Acquiror, there is no investment
banker, broker, finder or other intermediary which has been retained by or is
authorized to act on behalf of Acquiror or any of its Subsidiaries who might be
entitled to any fee or commission in connection with the transactions
contemplated by this Agreement.

      SECTION 4.17. Environmental Matters. Except as set forth in the Acquiror
SEC Documents filed prior to the date hereof and with such exceptions as,
individually or in the aggregate, have not had, and would not reasonably be
expected to have, a Material Adverse Effect on Acquiror, (i) no notice,
notification, demand, request for information, citation, summons, complaint or
order has been received by, and no investigation, action, claim, suit,
proceeding or review is pending or, to the knowledge of Acquiror or any of its
Subsidiaries, threatened by any Person against, Acquiror or any of its
Subsidiaries, and no penalty has been assessed against Acquiror or any of its
Subsidiaries, in each case, with respect to any matters relating to or arising
out of any Environmental Law; (ii) Acquiror and its Subsidiaries are and have
been in compliance with all Environmental Laws; (iii) there are no liabilities
of or relating to Acquiror or any of its Subsidiaries relating to or arising out
of any Environmental Law of any kind whatsoever, whether accrued, contingent,
absolute, determined, determinable or otherwise, and there is no existing
condition, situation or set of circumstances which could reasonably be expected
to result in such a liability; and (iv) there has been no environmental
investigation, study, audit, test, review or other analysis conducted of which
Acquiror has knowledge in relation to the current or prior business of Acquiror
or any of its Subsidiaries or any property or facility now or previously owned,
leased or operated by Acquiror or any of its Subsidiaries which has not been
delivered to the Company at least five days prior to the date hereof.

      SECTION 4.18.  Opinion of Financial Advisor.  Acquiror has received
the opinion of J.P.  Morgan Securities Inc. to the effect that, as of the
date of such opinion, the consideration to be paid by Acquiror in the
Merger is fair, from a financial point of view, to Acquiror, and, as of the
date hereof, such opinion has not been withdrawn.

      SECTION 4.19.  Pooling;  Tax Treatment.  (a)  Acquiror intends that
the Merger be accounted for as a "pooling of interests" as described in
Section 3.19(a).

     (b)  Neither Acquiror nor any of its affiliates has taken or agreed to
take any action or is aware of any fact or circumstance that would prevent
the Merger from qualifying (i) for "pooling of interests" accounting
treatment as described in Section 3.19(a) or (ii) as a 368 Reorganization.

      SECTION 4.20. Pooling Letter. Acquiror has received a letter from
PricewaterhouseCoopers LLP dated as of November 25, 1998 and addressed to
Acquiror, a copy of which has been delivered to the Company, stating that based
on the information furnished to PricewaterhouseCoopers LLP in the related
certificate of Acquiror's management and based on the letter from Ernst & Young
LLP referenced in Section 3.20, PricewaterhouseCoopers LLP concurs with Acquiror
management's conclusion that, as of November 25, 1998, no conditions exist that
would preclude Acquiror's accounting for the Merger as a pooling of interests,
and such letter has not been withdrawn or modified in any material respect as of
the date hereof.

(the "Company Stockholder Meeting") to be duly called and held as soon as
reasonably practicable, on a date reasonably acceptable to Acquiror, for the
purpose of voting on the approval and adoption of this Agreement and the Merger
(the "Company Stockholder Approval"). Except as provided in the next sentence,
the Board of Directors of the Company shall recommend approval and adoption of
this Agreement by the Company's stockholders. The Board of Directors of the
Company shall be permitted to (i) not recommend to the Company's shareholders
that they give the Company Stockholder Approval or (ii) withdraw or modify in a
manner adverse to Acquiror its recommendation to the Company's shareholders that
they give the Company Stockholder Approval, only (x) if the Board of Directors
of the Company by a majority vote determines in its good faith judgment that it

fiduciary duty to shareholders under applicable law, after receiving the advice
of outside legal counsel, and (y) if the Company and the senior officers and
directors of the Company have substantially complied with their obligations set
forth in Section 5.03. In connection with the Company Stockholder Meeting, the

the Company will use its reasonable best efforts to cause the officers,
directors, employees, investment bankers, consultants and other agents of the
Company and its Subsidiaries not to, directly or indirectly, take any action to
solicit, initiate, encourage or facilitate the making of any Acquisition
Proposal (including without limitation by amending, or granting any waiver
under, the Company Rights Agreement) or any inquiry with respect thereto or
engage in discussions or negotiations with any Person with respect thereto, or
disclose any non-public information relating to the Company or any Subsidiary of
the Company or afford access to the properties, books or records of the Company
or any Subsidiary of the Company to, any Person that has made, or to the
Company's knowledge, is considering making, any Acquisition Proposal; provided
that nothing contained in this Section 5.03 shall prevent the Company from
furnishing non-public information to, or entering into

                                   A-23
<PAGE>


Annex A -- Agreement and Plan of Merger


discussions or negotiations with, or affording access to the properties,
books or records of the Company or its Subsidiaries to, any Person in
connection with an unsolicited bona fide Acquisition Proposal received from
such Person so long as prior to furnishing non-public information to, or
entering into discussions or negotiations with, such Person, (i) the Board
of Directors of the Company by a majority vote determines in its good faith
judgment that it is necessary to do so to comply with its fiduciary duty to
shareholders under applicable law, after receiving the advice of outside
legal counsel, and (ii) the Company receives from such Person an executed
confidentiality agreement with terms no less favorable to the Company than
those contained in the Confidentiality Agreement (as defined in Section
7.03).  Nothing contained in this Agreement shall prevent the Board of
Directors of the Company from complying with Rule 14e-2 under the Exchange
Act with regard to an Acquisition Proposal; provided that the Board of
Directors of the Company shall not recommend that the shareholders of the
Company tender their shares in connection with a tender offer except to the
extent the Board of Directors of the Company by a majority vote determines
in its good faith judgment that such a recommendation is required to comply
with the fiduciary duties of the Board of Directors of the Company to
shareholders under applicable law, after receiving the advice of outside
legal counsel.  Unless the Board of Directors of the Company by a majority
vote determines in its good faith judgment that it is necessary not to do
so to comply with its fiduciary duty to shareholders under applicable law,
after receiving the advice of outside legal counsel, the Company will (a)
promptly (and in no event later than 48 hours after receipt of any
Acquisition Proposal) notify (which notice shall be provided orally and in
writing and shall identify the Person making such Acquisition Proposal and
set forth the material terms thereof)  Acquiror after receipt of any
Acquisition Proposal, any indication of which the Company has knowledge
that any Person is considering making an Acquisition Proposal or any
request for non-public information relating to the Company or any
Subsidiary of the Company or for access to the properties, books or records
of the Company or any Subsidiary of the Company by any Person that has
made, or to the Company's knowledge may be considering making, an
Acquisition Proposal, and (b) will keep Acquiror informed of the status and
material terms of any such Acquisition Proposal or request.  The Company
and its Subsidiaries will, and the Company will use its reasonable best
efforts to cause the officers, directors, employees, investment bankers,
consultants and other agents of the Company and its Subsidiaries to,
immediately cease and cause to be terminated all discussions and
negotiations, if any, that have taken place prior to the date hereof with
any parties with respect to any Acquisition Proposal.

      For purposes of this Agreement, "Acquisition Proposal" means any offer or
proposal for, or any indication of interest in, any (i) direct or indirect
acquisition or purchase of a business or assets that constitute 20% or more of
the net revenues, net income or the assets of the Company and its Subsidiaries,
taken as a whole, (ii) direct or indirect acquisition or purchase of 20% or more
of any class of equity securities of the Company or any of its Subsidiaries
whose business constitutes 20% or more of the net revenues, net income or assets
of the Company and its Subsidiaries, taken as a whole, (iii) tender offer or
exchange offer that if consummated would result in any person beneficially
owning 20% or more of any class of equity securities of the Company or any of
its Subsidiaries whose business constitutes 20% or more the net revenues, net
income or assets of the Company and its Subsidiaries, taken as a whole, or (iv)
merger, consolidation, business combination, recapitalization, liquidation,
dissolution or similar transaction involving the Company or any of its
Subsidiaries whose business constitutes 20% or more of the net revenue, net
income or assets of the Company and its Subsidiaries, taken as a whole, other
than the transactions contemplated by this Agreement. For purposes of this
Agreement, "Superior Proposal" means any bona fide Acquisition Proposal for or
in respect of at least a majority of the outstanding Shares on terms that the
Board of Directors of the Company determines in its good faith judgment (after
consultation with a financial advisor of nationally recognized reputation,
taking into account all the terms and conditions of the Acquisition Proposal,
including any break-up fees, expense reimbursement provisions and conditions to
consummation) are more favorable to all of the Company's stockholders than the
Merger.

Annex A -- Agreement and Plan of Merger


      SECTION 6.02. Obligations of Merger Subsidiary. Acquiror will take all
action necessary to cause Merger Subsidiary to perform its obligations under
this Agreement and to consummate the Merger on the terms and conditions set
forth in this Agreement.

      SECTION 6.03. Director and Officer Liability. (a) For seven years after
the Effective Time, Acquiror shall indemnify and hold harmless the individuals
who on or prior to the Effective Time were officers, directors and employees of
the Company or its Subsidiaries (collectively, the "Indemnitees") with respect
to all acts or omissions by them in their capacities as such or taken at the
request of the Company or any of its Subsidiaries at any time prior to the
Effective Time to the extent provided under the Company's certificate of
incorporation and by-laws in effect on the date hereof. Acquiror shall cause the
Surviving Corporation to honor all indemnification agreements with Indemnitees
(including under the Company's by-laws) in effect as of the date hereof in
accordance with the terms thereof. To the best knowledge of the Company, the
Company has disclosed to Acquiror all such indemnification agreements prior to
the date hereof.

     (b) For seven years after the Effective Time, Acquiror shall procure the
provision of officers' and directors' liability insurance in respect of acts or
omissions occurring prior to the Effective Time covering each such Person
currently covered by the Company's officers' and directors' liability insurance
policy on terms with respect to coverage and in amounts no less favorable than
those of such policy in effect on the date hereof (it being understood that
Acquiror may discharge its obligations pursuant to this paragraph by providing
an insurance policy underwritten by Ancon Insurance Company, Inc., a
wholly-owned Subsidiary of Acquiror); provided, that if the aggregate annual
premiums for such insurance at any time during such period shall exceed 300% of
the per annum rate of premium paid by the Company and its Subsidiaries as
of the date hereof for such insurance, then Acquiror shall, or shall cause
its Subsidiaries to, provide only such coverage as shall then be available
at an annual premium equal to 300% of such rate.

     (c) The obligations of Acquiror under this Section 6.03 shall not be
terminated or modified in such a manner as to adversely affect any Indemnitee to
whom this Section 6.03 applies without the consent of such affected Indemnitee
(it being expressly agreed that the Indemnitees to whom this Section 6.03
applies shall be third party beneficiaries of this Section 6.03).

      SECTION 6.04. Acquiror Stockholder Meeting; Form S-4. Unless the Board of
Directors of the Company shall take any action permitted by the third sentence
of Section 5.02, Acquiror shall cause a meeting of its stockholders (the
"Acquiror Stockholder Meeting") to be duly called and held as soon as reasonably
practicable, on a date reasonably acceptable to the Company, for the purpose of
approving the matters constituting the Acquiror Stockholder Approval. Except as
provided in the next sentence, the Board of Directors of Acquiror shall
recommend approval of the matters constituting the Acquiror Stockholder
Approval. The Board of Directors of Acquiror shall be permitted to (i) not
recommend to Acquiror's shareholders that they give the Acquiror Stockholder
Approval or (ii) withdraw or modify in a manner adverse to the Company its
recommendation to the Acquiror's shareholders that they give the Acquiror
Stockholder Approval, only if the Board of Directors of Acquiror by a majority
vote determines in its good faith judgment that it is necessary to so withdraw
or modify its recommendation to comply with its fiduciary duty to shareholders
under applicable law, after receiving the advice of outside legal counsel. In
connection with the Acquiror Stockholder Meeting, Acquiror (x) will promptly
prepare and file with the SEC, will use its reasonable best efforts to have
cleared by the SEC, and will thereafter mail to its stockholders as promptly as
practicable, the Acquiror Proxy Statement and all other proxy materials for such
meeting, (y) will use its reasonable best efforts, subject to the immediately
preceding sentence, to obtain the Acquiror Stockholder Approval, and (z) will
otherwise comply with all legal requirements applicable to the Acquiror
Stockholder Meeting. Subject to the terms and conditions of this Agreement and
unless the Board of Directors of the Company shall take any action permitted by
the third sentence of Section 5.02, Acquiror shall prepare and file with the SEC
under the 1933 Act the Form S-4, and shall use its reasonable best efforts to
cause the Form S-4 to be declared effective by the SEC as promptly as
practicable. Acquiror shall promptly take any action required to be taken under
foreign or state securities or Blue Sky laws in connection with the issuance of
Acquiror Common Stock in connection with the Merger. The parties acknowledge and
agree that

                                   A-26
<PAGE>


                                       Annex A -- Agreement and Plan of Merger


Acquiror may include in such proxy statement to be mailed to its
stockholders a proposal to amend Acquiror's certificate of incorporation to
eliminate the Class B Preferred Stock.

      SECTION 6.05. Stock Exchange Listing. Acquiror shall use its reasonable
best efforts to cause the shares of Acquiror Common Stock to be issued in
connection with the Merger to be listed on the NYSE, subject to official notice
of issuance.

      SECTION 6.06. Employee Benefits. (a) From and after the Effective Time,
Acquiror shall cause the Surviving Corporation to honor in accordance with their
terms all benefits and obligations under the Executive Arrangements (as defined
in Section 6.06(f)) and, subject to Section 6.06(b), the other Company Employee
Plans, each as in effect on the date hereof (or as amended with the prior
written consent of Acquiror), to the extent that entitlements or rights, actual
or contingent (whether such entitlements or rights are vested as of the
Effective Time or become vested or payable only upon the occurrence of a further
event, including a discretionary determination) exist in respect thereof as of
the Effective Time. Acquiror and the Company hereby agree that the consummation
of the Merger shall constitute a "Change in Control" for purpose of any employee
arrangement and all other Company Employee Plans, pursuant to the terms of such
plans in effect on the date hereof. No provision of this Section 6.06(a) shall
be construed as a limitation on the right of Acquiror to amend or terminate any
Company Employee Plans which the Company would otherwise have under the terms of
such Company Employee Plan, and no provision of this Section 6.06(a) shall be
construed to create a right in any employee or beneficiary of such employee
under a Company Employee Plan that such employee or beneficiary would not
otherwise have under the terms of such Company Employee Plan.

     (b) Following the Effective Time, Acquiror shall continue to provide to
individuals who are employed by the Company and its Subsidiaries as of the
Effective Time who remain employed with Acquiror or any Subsidiary of Acquiror
("Affected Employees"), for so long as such Affected Employees remain employed
by Acquiror or any Subsidiary of Acquiror, employee benefits (other than salary
or incentive compensation) (i) pursuant to the Company's or its Subsidiaries'
employee benefit plans, programs, policies and arrangements as provided to such
employees immediately prior to the Effective Time or (ii) pursuant to employee
benefit plans, programs, policies or arrangements maintained by Acquiror or any
Subsidiary of Acquiror providing coverage and benefits which, in the aggregate,
are no less favorable than those provided to employees of Acquiror in positions
comparable to positions held by Affected Employees with Acquiror or its
Subsidiaries from time to time after the Effective Time. Following the Effective
Time, Acquiror shall continue to provide to former employees of the Company or
its Subsidiaries (and to employees of the Company or its Subsidiaries whose
employment terminates prior to the Effective Time) ("Affected Retirees") post
retirement benefits (other than pensions) (i) pursuant to the Company Employee
Plans applicable to such Affected Retirees, each as in effect on the date
hereof, or (ii) pursuant to employee benefit plans, programs, policies or
arrangements maintained by Acquiror or any Subsidiary of Acquiror providing post
retirement coverage and benefits (other than pensions) which, in the aggregate,
are no less favorable than those provided to former employees of Acquiror.

     (c) Acquiror will, or will cause the Surviving Corporation to, give
Affected Employees full credit for purposes of eligibility, vesting, benefit
accrual (including benefit accrual under any defined benefit pension plans,
provided that a participant's benefit under any such defined benefit pension
plan may be offset by such participant's accrued benefit under the Company
defined benefit pension plan) and determination of the level of benefits under
any employee benefit plans or arrangements maintained by Acquiror or any
Subsidiary of Acquiror for such Affected Employees' service with the Company or
any Subsidiary of the Company to the same extent recognized by the Company
immediately prior to the Effective Time.

     (d) Acquiror will, or will cause the Surviving Corporation to, (i) waive
all limitations as to preexisting conditions, exclusions and waiting periods
with respect to participation and coverage requirements applicable to the
Affected Employees under any welfare benefit plans that such employees may be
eligible to participate in after the Effective Time, other than limitations or
waiting periods that are already in effect with respect to such employees and

                                   A-27

Annex A -- Agreement and Plan of Merger


that have not been satisfied as of the Effective Time under any welfare plan
maintained for the Affected Employees immediately prior to the Effective Time,
and (ii) provide each Affected Employee with credit for any co-payments and
deductibles paid prior to the Effective Time in satisfying any applicable
deductible or out-of-pocket requirements under any welfare plans that such
employees are eligible to participate in after the Effective Time.

     (e) Acquiror (i) acknowledges that the Company's Board and the Management
Compensation and Organization Committee (the "MCOC") of the Company's Board has
determined that all officers and employees covered by the Company Management
Retention Plan have performed at a level satisfactory to the Company over the
period that the conditional retention awards granted thereunder have been
outstanding and, accordingly, that all such individuals would be entitled to
full payment under the Company Management Retention Plan were they to retire or
otherwise terminate their employment with the Company or any of its Subsidiaries
and (ii) agrees to give considerable weight to such determination in
administering the Company Management Retention Plan after the Effective Time,
given the significant length of time that has elapsed since the award grants.

     (f) Acquiror agrees that the 1986, 1991 and 1995 Company Incentive
Compensation and Stock Ownership Plans, the Company Management Retention Plan,
the Supplemental Pension Annuity Program of Mobil Corporation, the Executive
Life Insurance Program of Mobil Corporation and the Company Employee Severance
Plan (collectively, the "Executive Arrangements"), as well as any award made
under any Executive Arrangement (including Company Stock Options and Company
Awards), shall be administered in accordance with the past practices and
interpretations of the Company's Board and the MCOC (including those past
practices and interpretations previously disclosed by the Company to
Acquiror) with respect to eligibility, vesting, term and payment, among
other matters.  Any question regarding the past practices and
interpretations of the Company's Board and the MCOC and the application
thereof to the type of facts and circumstances in a given case shall be
referred to Mr.  Lucio A.  Noto or his designee for a final decision with
respect thereto, which decision shall not be inconsistent with the
intention of this Agreement and the Merger.


                                 ARTICLE 7
                   COVENANTS OF ACQUIROR AND THE COMPANY

      have failed to recommend or withdrawn or modified or changed in a
      manner adverse to Acquiror its approval or recommendation of this
      Agreement or the Merger, or shall have failed to call the Company
      Stockholder Meeting in accordance with Section 5.02, or shall have
      recommended a Superior Proposal (or the Board of Directors of the

      authorizes the Company, subject to complying with the terms of this
      Agreement, to enter into a binding written agreement concerning a
      transaction that constitutes a Superior Proposal and the Company
      notifies Acquiror in writing that it intends to enter into such an
      agreement, attaching the most current version of such agreement (or a
      description of all material terms and conditions thereof) to such
      notice, (ii)  Acquiror does not make, within three business days of
      receipt of the Company's written notification of its intention to
      enter into a binding agreement for a Superior Proposal, an offer that
      the Board of Directors of the Company determines, in good faith after
      consultation with its financial advisors, is at least as favorable to
      the shareholders of the Company as the Superior Proposal, it being
      understood that the Company shall not enter into any such binding
      agreement during such three day period and (iii) the Company prior to
      such termination pursuant to this clause (e) pays to Acquiror in
      immediately available funds the fees required to be paid pursuant to

      intention to enter into a written agreement referred to in its
      notification shall change at any time after giving such notification;

      failed to call the Acquiror Stockholder Meeting in accordance with
      Section 6.04 (or the Board of Directors of Acquiror resolves to do
      any of the foregoing).

the Confidentiality Agreement shall survive the termination hereof and (b) no
such termination shall relieve any party of any liability or damages resulting
from any willful breach by that party of this Agreement.

Annex A -- Agreement and Plan of Merger


     (b)  If:

          (i) the Company shall terminate this Agreement pursuant to
     Section 9.01(e);

         (ii)  Acquiror shall terminate this Agreement pursuant to Section
     9.01(d), unless at the time of such failure to recommend, withdrawal
     or adverse modification or change, failure to call the Company
     Stockholder Meeting or recommendation of a Superior Proposal, any of
     the conditions set forth in Section 8.03(a) or 8.03(c) would not have
     been satisfied as of such date and would not be reasonably capable of
     being satisfied; or

        (iii) either the Company or Acquiror shall terminate this Agreement
      pursuant to Section 9.01(b)(ii) in circumstances where the Company
      Stockholder Approval has not been obtained and prior to the Company
      Stockholder Meeting an Acquisition Proposal is made by any Person and
      the Company enters into a definitive agreement within twelve months
      after termination of this Agreement either (1) in respect of any
      Acquisition Proposal with such Person or its affiliate or (2) in
      respect of any Acquisition Proposal with any other Person (other than
      Acquiror or any affiliate of Acquiror) providing, in the case of this
      clause (2), greater value per Share than the Exercise Price (as
      defined in the Option Agreement),

then in any case as described in clause (i), (ii) or (iii) (each such case of
termination being referred to as a "Trigger Event") the Company shall pay to
Acquiror (by wire transfer of immediately available funds not later than the
date of termination of this Agreement or, in the case of clause (iii), the date
of such definitive agreement) an amount equal to $1,500,000,000. Acceptance by
Acquiror of the payment referred to in the foregoing sentence shall constitute
conclusive evidence that this Agreement has been validly terminated and upon
acceptance of payment of such amount the Company shall be fully released and
discharged from any liability or obligation resulting from or under this
Agreement (but without limiting the Company's obligations under the Option
Agreement).

     (c) If the Company shall terminate this Agreement pursuant to Section
9.01(f) unless at the time of such failure to recommend, withdrawal or adverse
modification or change or failure to call the Acquiror Stockholder Meeting any
of the conditions set forth in Section 8.02(a) or 8.02(f) would not have been
satisfied as of such date and would not be reasonably capable of being
satisfied, then Acquiror shall pay to the Company (by wire transfer of
immediately available funds not later than the date of termination of this
Agreement) an amount equal to $1,500,000,000. Acceptance by the Company of the
payment referred to in the foregoing sentence shall constitute conclusive
evidence that this Agreement has been validly terminated and upon acceptance of
payment of such amount the Acquiror shall be fully released and discharged from
any liability or obligation resulting from or under this Agreement.

     SECTION 10.05. Successors and Assigns. The provisions of this Agreement
shall be binding upon and inure to the benefit of the parties hereto and their
respective successors and assigns; provided that no party may assign, delegate
or otherwise transfer any of its rights or obligations under this Agreement
without the consent of the other parties hereto except that Merger Subsidiary
may transfer or assign, in whole or from time to time in part, to one or more of
its affiliates, its rights under this Agreement, but any such transfer or
assignment will not relieve Merger Subsidiary of its obligations hereunder.

     SECTION 10.06.  Governing Law.  This Agreement shall be construed in
accordance with and governed by the law of the State of Delaware, without
regard to principles of conflicts of law.

     SECTION 10.07. Jurisdiction. Any suit, action or proceeding seeking to
enforce any provision of, or based on any matter arising out of or in connection
with, this Agreement or the transactions contemplated hereby may be brought in
any federal or state court located in the State of Delaware, and each of the
parties hereby consents to the jurisdiction of such courts (and of the
appropriate appellate courts therefrom) in any such suit, action or proceeding
and irrevocably waives, to the fullest extent permitted by law, any objection
which it may now or hereafter have to the laying of the venue of any such suit,
action or proceeding in any such court or that any such suit, action or
proceeding which is

brought in any such court has been brought in an inconvenient forum.
Process in any such suit, action or proceeding may be served on any party
anywhere in the world, whether within or without the jurisdiction of any
such court.  Without limiting the foregoing, each party agrees that service
of process on such party as provided in Section 10.01 shall be deemed
effective service of process on such party.

     SECTION 10.08. Waiver of Jury Trial. EACH OF THE PARTIES HERETO HEREBY
IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING
ARISING OUT OF OR RELATED TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED
HEREBY.

     SECTION 10.09. Counterparts; Effectiveness. This Agreement may be signed in
any number of counterparts, each of which shall be an original, with the same
effect as if the signatures thereto and hereto were upon the same instrument.
This Agreement shall become effective when each party hereto shall have received
counterparts hereof signed by all of the other parties hereto.

     SECTION 10.10. Entire Agreement. This Agreement (including the Exhibits and
Schedules hereto), the Option Agreement and the Confidentiality Agreement
constitute the entire agreement between the parties with respect to the subject
matter of this Agreement and supersede all prior agreements and understandings,
both oral and written, between the parties with respect to the subject matter
hereof and thereof. Except as provided in Section 6.03(c), no provision of this
Agreement or any other agreement contemplated hereby is intended to confer on
any Person other than the parties hereto any rights or remedies.

     SECTION 10.11.  Captions.  The captions herein are included for
convenience of reference only and shall be ignored in the construction or
interpretation hereof.

     SECTION 10.12. Severability. If any term, provision, covenant or
restriction of this Agreement is held by a court of competent jurisdiction or
other authority to be invalid, void or unenforceable, the remainder of the
terms, provisions, covenants and restrictions of this Agreement shall remain in
full force and effect and shall in no way be affected, impaired or invalidated
so long as the economic or legal substance of the transactions contemplated
hereby is not affected in any manner materially adverse to any party. Upon such
a determination, the parties shall negotiate in good faith to modify this
Agreement so as to effect the original intent of the parties as closely as
possible in an acceptable manner in order that the transactions contemplated
hereby be consummated as originally contemplated to the fullest extent possible.

Ladies and Gentlemen:

     The undersigned has been advised that as of the date of this letter the
undersigned may be deemed to be an "affiliate" of Mobil Corporation, a Delaware
corporation (the "Company"), as the term "affiliate" is defined for purposes of
paragraphs (c) and (d) of Rule 145 of the rules and regulations (the "Rules and
Regulations") of the Securities and Exchange Commission (the "Commission") under
the Securities Act of 1933, as amended (the "Act"). Pursuant to the terms of the
Agreement and Plan of Merger dated as of December 1, 1998 (the "Agreement")
among the Company, Exxon Corporation, a New Jersey corporation ("Exxon"), and
Lion Acquisition Subsidiary Corporation, a Delaware corporation and a
wholly-owned subsidiary of Exxon ("Merger Subsidiary"), Merger Subsidiary will
be merged with and into the Company with the Company to be the surviving
corporation in the merger (the "Merger").

     As a result of the Merger, the undersigned will receive shares of common
stock, no par value, of Exxon (the "Exxon Common Stock") in exchange for shares
owned by the undersigned of common stock, par value $1.00 per share, of the
Company (the "Company Common Stock").

     The undersigned represents, warrants and covenants to Exxon and the Company
that as of the date the undersigned receives any Exxon Common Stock as a result
of the Merger:

     A. The undersigned shall not make any sale, transfer or other disposition
of the Exxon Common Stock in violation of the Act or the Rules and Regulations.

     B. The undersigned has carefully read this letter and the Agreement and
discussed the requirements of such documents and other applicable limitations
upon the undersigned's ability to sell, transfer or otherwise dispose of the
Exxon Common Stock to the extent the undersigned felt necessary with the
undersigned's counsel or counsel for the Company.

     C. The undersigned has been advised that the issuance of Exxon Common Stock
to the undersigned pursuant to the Merger will be registered with the Commission
under the Act on a Registration Statement on Form S-4. However, the undersigned
has also been advised that, because at the time the Merger is submitted for a
vote of the stockholders of the Company, the undersigned may be deemed to be an
affiliate of the Company, the undersigned may not sell, transfer or
otherwise dispose of the Exxon Common Stock issued to the undersigned in

<PAGE>


                                       Annex A -- Agreement and Plan of Merger


the Merger unless (i) such sale, transfer or other disposition has been
registered under the Act, (ii) such sale, transfer or other disposition is
made in conformity with Rule 145 promulgated by the Commission under the
Act, or (iii) in the opinion of counsel reasonably acceptable to Exxon, or
pursuant to a "no action" letter obtained by the undersigned from the staff
of the Commission, such sale, transfer or other disposition is otherwise
exempt from registration under the Act.

     D. The undersigned understands that Exxon is under no obligation to
register the sale, transfer or other disposition of the Exxon Common Stock by
the undersigned or on the undersigned's behalf under the Act or to take any
other action necessary in order to enable such sale, transfer or other
disposition by the undersigned to be made in compliance with an exemption from
such registration.

     E. The undersigned also understands that there will be placed on any
certificates for the Exxon Common Stock issued to the undersigned a legend
stating in substance:

     "THE SECURITIES REPRESENTED BY THIS CERTIFICATE WERE ISSUED IN A
     TRANSACTION TO WHICH RULE 145 PROMULGATED UNDER THE SECURITIES ACT
     OF 1933 APPLIES. THE SECURITIES REPRESENTED BY THIS CERTIFICATE
     MAY BE SOLD, TRANSFERRED OR OTHERWISE DISPOSED OF ONLY IN
     ACCORDANCE WITH THE TERMS OF A LETTER AGREEMENT BETWEEN THE
     REGISTERED HOLDER HEREOF AND EXXON CORPORATION, A COPY OF WHICH
     AGREEMENT IS ON FILE AT THE PRINCIPAL OFFICES OF EXXON
     CORPORATION."

     F. The undersigned also understands that unless a sale or transfer by the
undersigned of the undersigned's Exxon Common Stock has been registered under
the Act or is a sale made in conformity with the provisions of Rule 145 under
the Act, Exxon reserves the right to put the following legend on the
certificates issued to the undersigned's transferee:

     "THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN
     REGISTERED UNDER THE SECURITIES ACT OF 1933 AND WERE ACQUIRED FROM
     A PERSON WHO RECEIVED SUCH SECURITIES IN A TRANSACTION TO WHICH
     RULE 145 PROMULGATED UNDER THE SECURITIES ACT OF 1933 APPLIES. THE
     SECURITIES HAVE NOT BEEN ACQUIRED BY THE HOLDER WITH A VIEW TO, OR
     FOR RESALE IN CONNECTION WITH, ANY DISTRIBUTION THEREOF WITHIN THE
     MEANING OF THE SECURITIES ACT OF 1933 AND MAY NOT BE SOLD,
     TRANSFERRED OR OTHERWISE DISPOSED OF EXCEPT PURSUANT TO AN
     EFFECTIVE REGISTRATION STATEMENT OR IN ACCORDANCE WITH AN
     EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT
     OF 1933."

     It is understood and agreed that the legends set forth in paragraphs E and
F above shall be removed by delivery of substitute certificates without such
legend if (i) the securities represented thereby have been registered for sale
by the undersigned under the Act or (ii) Exxon has received either an opinion of
counsel, which opinion and counsel shall be reasonably satisfactory to Exxon, or
a "no-action" letter obtained by the undersigned from the staff of the
Commission, to the effect that the restrictions imposed by Rule 145 under the
Act no longer apply to the undersigned.

     G. The undersigned further understands and agrees that the representations,
warranties, covenants and agreements of the undersigned set forth herein are for
the benefit of Exxon, the Company and the Surviving Corporation (as defined
in the Merger Agreement) and will be relied upon by such entities and their
respective counsel and accountants.

Ladies and Gentlemen:

     In connection with the opinions to be delivered pursuant to Sections
8.02(e) and 8.03(b) of the Agreement and Plan of Merger (the "Agreement")* dated
as of December 1, 1998, among Mobil, a Delaware corporation ("Company"), Exxon,
a New Jersey corporation ("Parent"), and Lion Acquisition Subsidiary
Corporation, a Delaware corporation and a wholly-owned subsidiary of Parent
("Merger Subsidiary"), and the opinions which, pursuant to the requirements of
Item 601(b)(8) of Regulation S-K under the Securities Act of 1933, as amended,
will be included in the Registration Statement on Form S-4, the undersigned
officers of Parent and Merger Subsidiary hereby certify and represent as to
Parent and Merger Subsidiary that the facts relating to the merger (the
"Merger") of Merger Subsidiary with and into Company pursuant to the Agreement,
and as described in the Joint Proxy Statement/Prospectus of Parent and Company
relating to the Merger (the "Proxy Statement") are true, correct and complete in
all respects as of the date hereof and will be true, correct and complete in all
respects at the Effective Time and that:

       1. The Merger Consideration and Preferred Merger Consideration to be
received in the Merger by holders of common stock of Company ("Company Stock")
and Series B Preferred Stock of Company ("Series B Preferred Stock"),
respectively, was determined by arm's length negotiations between the
managements of Parent and Company and will be approximately equal to the fair
market value of the Company Stock and Series B Preferred Stock, respectively,
surrendered in exchange. In connection with the Merger, no holder of Company
Stock will receive in exchange for such stock, directly or indirectly, any
consideration other than common stock of Parent ("Parent Stock") and, in lieu of
fractional shares of Parent Stock, cash. In connection with the Merger, no
holder of Series B Preferred Stock, other than any such holders who dissent in
the merger and perfect their right to appraisal and payment, will receive in
exchange for such stock, directly or indirectly, any consideration other than
preferred stock to be issued by Parent ("Parent Preferred Stock") at the
Effective Time.

       2. Other than cash paid in lieu of fractional shares of Parent Stock,
none of

Annex A -- Agreement and Plan of Merger


          (i)  Parent (or any successor corporation),

         (ii) a corporation that, immediately before or immediately after
      such purchase, exchange, redemption, or other acquisition, is a
      member of an Affiliated Group (as defined herein) of which Parent (or
      any successor corporation) is a member, or

        (iii) a corporation in which Parent (or any successor corporation)
      owns, or which owns with respect to Parent (or any successor
      corporation), directly or indirectly, immediately before or
      immediately after such purchase, exchange, redemption, or other
      acquisition, at least 50% of the total combined voting power of all
      classes of stock entitled to vote or at least 50% of the total value
      of shares of all classes of stock, taking into account for purposes
      of this clause (iii)

               o any stock owned by 5% or greater stockholders of Parent
                 (or any successor) or such corporation,

               o a proportionate share of the stock owned by entities in
                 which Parent (or any successor) or such corporation owns an
                 interest, and

               o any stock which may be acquired pursuant to the exercise
                 of options

(a "Parent Related Person") has any current plan or intention to redeem,
purchase, exchange or otherwise reacquire any of the Parent Stock or Parent
Preferred Stock to be issued in the Merger. Parent will implement its stock
repurchase plan consistent with the resolution adopted by the Board of Parent on
November 25, 1998. Parent intends that all stock repurchases made pursuant to
this stock repurchase plan, or any other stock repurchase plan adopted by
Parent,

          (a)  shall be undertaken for a corporate business purpose,

          (b) shall be made in the open market for stock of the Parent
      which is widely held and publicly traded, except that Parent may
      acquire stock in block trades made directly with an entity that is
      not known to Parent to have acquired such stock in the Merger, and
      any redemptions or repurchases of stock issued in the Merger that
      occur shall be incidental to the operation of such stock repurchase
      plan, and

           (c) shall be limited to, in the aggregate, a small percentage of
      each class of stock of Parent outstanding at the time of the
      redemption or repurchase.

     In addition, Parent will cause all Parent Related Persons and any person
acting as an agent of Parent not to redeem, purchase, exchange or otherwise
acquire (including by derivative transactions such as an equity swap which would
have the economic effect of an acquisition), directly or indirectly (including
through partnerships or through third parties in connection with a plan to so
acquire), a number of shares of Parent Stock and Parent Preferred Stock to be
received by Company shareholders in connection with the Merger that would reduce
the Company shareholders' ownership of Parent Stock and Parent Preferred Stock
to a number of shares having a value, as of the Effective Time, of less than 50%
of the total value of Company Stock and Series B Preferred Stock immediately
prior to the Effective Time.

     For purposes of this representation, shares of Company Stock exchanged for
cash in lieu of fractional shares of Parent Stock are treated as outstanding
shares of Company Stock at the Effective Time. Moreover, shares of
Company Stock and Series B Preferred Stock that are redeemed or sold or
otherwise transferred to Company,

                                       Annex A -- Agreement and Plan of Merger


Parent, or any person related to Company or Parent prior to the Merger and
in contemplation or as part of the Merger will be taken into account for
purposes of this representation.

     For purposes of this Certificate, "Affiliated Group" shall mean one or more
chains of corporations connected through stock ownership with a common parent
corporation, but only if

           (x) the common parent owns directly stock that possesses at
     least 80% of the total voting power, and has a value at least equal to
     80% of the total value, of the stock in at least one of the other
     corporations, and

           (y) stock possessing at least 80% of the total voting power, and
     having a value at least equal to 80% of the total value, of the stock
     in each corporation (except the common parent) is owned directly by
     one or more of the other corporations.

     For purposes of the preceding sentence, "stock" does not include any
     stock which

           (a) is not entitled to vote,

           (b) is limited and preferred as to dividends and does not
     participate in corporate growth to any significant extent,

           (c) has redemption and liquidation rights which do not exceed
     the issue price of such stock (except for a reasonable redemption or
     liquidation premium), and

           (d) is not convertible into another class of stock.

       3. After the Merger, Company will hold at least 90% of the fair market
value of the net assets and at least 70% of the fair market value of the gross
assets held by Merger Subsidiary immediately prior to the Merger, and at least
90% of the fair market value of the net assets and at least 70% of the fair
market value of the gross assets held by Company immediately prior to the
Merger. For purposes of this representation, assets of Merger Subsidiary or
Company held immediately prior to the Merger include amounts paid or incurred by
Merger Subsidiary or Company in connection with the Merger, including amounts
used to pay reorganization expenses or dissenting shareholders or to make
payments to shareholders who receive cash or other property (including cash in
lieu of fractional shares) and all payments, redemptions and distributions
(except for regular, normal dividends) made in contemplation or as part of the
Merger.

       4. Prior to and at the Effective Time of the Merger, Parent will be in
Control of Merger Subsidiary. Merger Subsidiary is wholly and directly owned by
Parent and has been newly formed solely in order to consummate the Merger, and
at no time has or will Merger Subsidiary conduct any business activities or
other operations of any kind other than the issuance of its stock to Parent
prior to the Effective Time. For purposes of this Certificate, "Control" with
respect to a corporation shall mean ownership of at least 80% of the total
combined voting power of all classes of stock entitled to vote and at least 80%
of the total number of shares of each other class of stock of the corporation.

       5. Following the Merger, Parent has no plan or intention to cause Company
to issue additional shares of stock, or any plan or intention to take any
action, that could result in Parent losing Control of Company.

       6. Parent has no plan or intention to liquidate Company, to merge Company
with or into another corporation, to sell, exchange, transfer or otherwise
dispose of any stock of Company or to cause Company to sell, exchange,
transfer or otherwise dispose of any of its assets or of any assets
acquired from Merger Subsidiary in the Merger, except for (i) dispositions
made in the ordinary course of business, (ii) transfers or successive
transfers if






                                  A-C-1-3
<PAGE>


Annex A -- Agreement and Plan of Merger


in each case the transferor is in Control of the transferee, or (iii) arm's
length dispositions to unrelated persons other than dispositions which
would result in Parent ceasing to use a significant portion of the
Company's historic business assets in a business.

       7. In the Merger, Merger Subsidiary will have no liabilities assumed by
Company and will not transfer to Company any assets subject to liabilities.

       8. Following the Merger, Parent will cause Company to continue its
historic business or use a significant portion of its historic business assets
in a business. For this purpose, Parent will be treated as holding all of the
businesses and assets of its Qualified Group and Parent will be treated as
owning its proportionate share of the Company business assets used in a business
of any partnership in which members of Parent's Qualified Group either own a
significant interest or have active and substantial management functions as a
partner with respect to that partnership business. A Qualified Group is one or
more chains of corporations connected through stock ownership with Parent but
only if Parent is in Control of at least one other corporation and each of the
corporations (other than Parent) is Controlled directly by one of the other
corporations.

       9. Except as provided below, Parent, Merger Subsidiary, Company and the
Company shareholders each will bear its or their own expenses, if any, incurred
in connection with or as part of the Merger or related transactions. However, to
the extent any expenses related to the Merger are to be funded directly or
indirectly by a party other than the incurring party, such expenses are solely
and directly related to the Merger, and do not include expenses incurred for
investment or estate planning advice, or expenses incurred by an individual
shareholder or group of shareholders for legal, accounting or investment advice
or counsel relating to the merger. Neither Parent nor Merger Subsidiary has paid
or will pay, directly or indirectly, any expenses (including transfer taxes)
incurred or to be incurred by any holder of Company Stock or Series B Preferred
Stock in connection with or as part of the Merger or any related transactions;
provided that any stamp duties and stamp duty reserve taxes in connection with
the issuance and creation of Parent Stock or Series B Preferred Stock of Parent
in the Merger will be paid by Parent. Neither Parent nor Merger Subsidiary has
agreed to assume, nor will it directly or indirectly assume, any other expense
or other liability, whether fixed or contingent, of any holder of Company Stock
or Series B Preferred Stock. To the extent that any transfer tax or other
expense is a liability of a shareholder of Company, such liability will be paid
by Company or such shareholder, but in no event by Parent.

      10. There is no intercorporate indebtedness existing between Parent and
Company or between Merger Subsidiary and Company that was issued, acquired or
will be settled at a discount.

      11. All shares of Parent Stock into which shares of Company Stock will be
converted pursuant to the Merger will be newly issued or treasury shares, and
will be issued by Parent directly to record holders of Company Stock pursuant to
the Merger. All shares of Parent Preferred Stock into which Series B Preferred
Stock will be converted will be newly issued and will be issued by Parent
directly to record holders of Series B Preferred Stock pursuant to the Merger.

      12. In the Merger, shares of Company Stock and Series B Preferred Stock
representing Control of Company will be exchanged solely for voting stock of
Parent and cash in lieu of fractional shares. Under the Agreement, all shares of
Company Stock and Series B Preferred Stock as to which dissenters' rights are
not perfected will be exchanged in the Merger for voting stock of Parent and
cash in lieu of fractional shares. For purposes of this representation, if any
stock of Company is exchanged for cash or other property originating with
Parent, such stock will be treated as outstanding stock of Company acquired by
Parent at the Effective Time. The payment of cash in lieu of fractional shares
of Parent Stock to holders of Company Stock is solely for the purpose of
avoiding the expense and inconvenience to Parent of issuing fractional
shares and does not represent separately bargained for consideration.  To
the best knowledge of the management of Parent, the total cash
consideration that will be paid in






                                  A-C-1-4
<PAGE>


                                       Annex A -- Agreement and Plan of Merger


the Merger to holders of Company Stock instead of issuing fractional shares
of Parent Stock will not exceed one percent of the total consideration that
will be issued to the holders of Company Stock in the Merger.

      13. In the Merger, no liabilities of shareholders of Company will be
assumed by Parent, and Parent will not assume any liabilities relating to any
Company Stock or Series B Preferred Stock acquired by Parent in the Merger.
Furthermore, there is no plan or intention for Parent to assume any liabilities
of Company.

      14. The Series B Preferred Stock is the only class of stock of Company
that grants its holders dissenters' rights. In the event that any holders of
Series B Preferred Stock of Company do not vote in favor of the Merger and
perfect their right to appraisal and payment, any amounts paid to such holders
in an appraisal proceeding will be paid by Company out of its own funds. No
funds will be supplied for such payments, directly or indirectly, by Parent, nor
will Parent directly or indirectly reimburse Company for any such payments.

      15. Neither Parent nor Merger Subsidiary is a regulated investment
company, a real estate investment trust, or a corporation fifty percent (50%) or
more of the value of whose assets are stock and securities and eighty percent
(80%) or more of the value of whose total assets are assets held for investment
(each, an "Investment Company"). For purposes of this representation, in making
the 50% and 80% determinations under the preceding sentence, (i) stock and
securities in any subsidiary corporation shall be disregarded and the parent
corporation shall be deemed to own its ratable share of the subsidiary's assets,
and (ii) a corporation shall be considered a subsidiary if the parent owns 50%
or more of the combined voting power of all classes of stock entitled to vote or
50% or more of the total value of shares of all classes of stock outstanding. In
determining total assets there shall be excluded cash and cash items (including
receivables), government securities, and assets acquired (through incurring
indebtedness or otherwise) for purposes of ceasing to be an Investment Company.

      16. None of the employee compensation received or to be received by any
shareholder-employees of Company is or will be separate consideration for, or
allocable to, any of their shares of Company Stock or Series B Preferred Stock
to be surrendered in the Merger. None of the shares of Parent Stock or Parent
Preferred Stock to be received by any shareholder-employee of Company in the
Merger is or will be separate consideration for, or allocable to, any
employment, consulting or similar arrangement. Any compensation paid or to be
paid to any shareholder of Company, who will be an employee of or perform
advisory services for Parent, Company, or any affiliate thereof after the
Merger, will be determined by bargaining at arm's length.

      17. At the Effective Time, neither Parent nor any Parent Related Person
will own any class of stock of Company or any securities of Company or any
instrument giving the holder the right to acquire any such stock or securities
except for the Option Agreement that appears as Exhibit A to the Agreement.

      18. The Merger is being effected for bona fide business reasons and will
be carried out strictly in accordance with the Agreement, and as described in
the Proxy Statement, and none of the material terms and conditions therein have
been or will be waived or modified.

      19. The Agreement and the documents described in the Agreement, the Proxy
Statement and the Form S-4 represent the entire understanding between or among
(i) Parent and its subsidiaries and (ii) Company and its subsidiaries and, to
the best knowledge of the management of Parent, between or among such entities
and the affiliates and shareholders of Parent and Company with respect to the
Merger and there are no written or oral agreements regarding the Merger other
than those expressly referred to in the Agreement, the Proxy Statement and the
Form S-4.

      20. None of Parent, Merger Subsidiary or, after the Merger, Company will
take any position on any Federal, state, or local income or franchise tax
return, or take any other tax reporting position, that is inconsistent with the
treatment of the Merger as a tax-free reorganization or any of the foregoing
representations, unless otherwise






                                  A-C-1-5

Annex A -- Agreement and Plan of Merger


required by a decision by the Tax Court or a judgment, decree, or other
order by any court of competent jurisdiction, which has become final, or by
applicable state or local income or franchise tax law.

      21. Except for cash in lieu of fractional shares, Parent will acquire the
Company Stock and the Series B Preferred Stock solely in exchange for voting
shares of Parent Stock and Parent Preferred Stock. For purposes of this
representation, stock of Company redeemed for cash or other property furnished
by Parent will be considered as acquired by Parent. Further, no liabilities of
Company or the Company shareholders will be assumed by Parent, and Parent will
not assume any liabilities relating to any Company Stock or Series B Preferred
Stock acquired by Parent in the Merger.

     We understand that Davis Polk & Wardwell and Skadden, Arps, Slate, Meagher
& Flom LLP will rely, without further inquiry, on this Certificate in rendering
their opinions as to certain United States Federal income tax consequences of
the Merger, and we will promptly and timely inform them if, after signing this
Certificate, we have reason to believe that any of the facts described herein or
in the Proxy Statement or any of the representations made in this Certificate
are or have become untrue, incorrect or incomplete in any respect.

Ladies and Gentlemen:

     In connection with the opinions to be delivered pursuant to Sections
8.02(e) and 8.03(b) of the Agreement and Plan of Merger (the "Agreement")* dated
as of December 1, 1998, among Mobil, a Delaware corporation ("Company"), Exxon,
a New Jersey corporation ("Parent"), and Lion Acquisition Subsidiary
Corporation, a Delaware corporation and a wholly-owned subsidiary of Parent
("Merger Subsidiary"), and the opinions which, pursuant to the requirements of
Item 601(b)(8) of Regulation S-K under the Securities Act of 1933, as amended,
will be included in the Registration Statement on Form S-4, the undersigned
officer of Company hereby certifies and represents as to Company that the facts
relating to the merger (the "Merger") of Merger Subsidiary with and into Company
pursuant to the Agreement and as described in the Joint Proxy
Statement/Prospectus of Parent and Company relating to the Merger (the "Proxy
Statement") are true, correct and complete in all respects as of the date hereof
and will be true correct and complete in all respects at the Effective Time and
that:

       1. The Merger Consideration and Preferred Merger Consideration to be
received in the Merger by holders of common stock of the Company ("Company
Stock") and Series B Preferred Stock of Company ("Series B Preferred Stock"),
respectively, was determined by arm's length negotiations between the
managements of Parent and Company and will be approximately equal to the fair
market value of the Company Stock and Series B Preferred Stock, respectively,
surrendered in exchange. In connection with the Merger, no holder of Company
Stock will receive in exchange for such stock, directly or indirectly, any
consideration other than common stock of Parent ("Parent Stock") and, in lieu of
fractional shares of Parent Stock, cash. In connection with the Merger, no
holder of Series B Preferred Stock of Company, other than any such holders who
dissent in the Merger and perfect their right to appraisal and payment, will
receive in exchange for such stock, directly or indirectly, any consideration
other than preferred stock to be issued by Parent ("Parent Preferred Stock") at
the Effective Time.

       2. To the best knowledge of the management of Company, there is no plan
or intention on the part of holders of Company Stock or Series B Preferred Stock
to sell, exchange or otherwise transfer ownership (including by derivative
transactions such as a an equity swap which would have the economic effect of a
transfer of ownership) to Parent, Company or any Related Person with
respect to either of them, directly or indirectly

- ------------
     *References contained in this Certificate to the Agreement include, unless
the context otherwise requires, each document attached as an exhibit or annex.
All defined terms used herein and not otherwise defined have the meaning
ascribed to them in the Agreement.

Annex A -- Agreement and Plan of Merger


(including through partnerships or through third parties in connection with
a plan to so transfer ownership), of a number of shares of Parent Stock or
Parent Preferred Stock to be received by Company shareholders in connection
with the Merger that would reduce the Company shareholders' ownership of
Parent Stock and Parent Preferred Stock to a number of shares having a
value, as of the Effective Time, of less than 50% of the total value of all
of the formerly outstanding stock of Company immediately prior to the
Effective Time.  For purposes of this representation, shares of Company
Stock exchanged for cash in lieu of fractional shares of Parent Stock and
Series B Preferred Stock redeemed pursuant to the perfection of the
holder's appraisal rights are treated as outstanding shares of Company
Stock or Series B Preferred Stock at the Effective Time.  Moreover, shares
of Company Stock and Parent Stock and Parent Preferred Stock held by
shareholders of Company that are redeemed or sold or otherwise transferred
to Company, Parent, or any person related to Company or Parent prior or
subsequent to the Merger and in contemplation or as part of the Merger will
be taken into account for purposes of this representation.

     For purposes of this Certificate, a Related Person with respect to either
Parent or Company shall mean

          (i) a corporation that, immediately before or immediately after
     such purchase, exchange, redemption, or other acquisition, is a member
     of an Affiliated Group (as defined herein) of which Parent or Company,
     as the case may be, (or any successor corporation) is a member, or

         (ii) a corporation in which Parent or Company, as the case may be,
     (or any successor corporation), owns, or which owns with respect to
     Parent or Company, as the case may be, (or any successor corporation)
     directly or indirectly, immediately before or immediately after such
     purchase, exchange, redemption, or other acquisition, at least 50% of
     the total combined voting power of all classes of stock entitled to
     vote or at least 50% of the total value of shares of all classes of
     stock, taking into account for purposes of this clause (ii) any stock
     owned by 5% or greater stockholders of Parent or Company, as the case
     may be, (or any successor) or such corporation, a proportionate share
     of the stock owned by entities in which Parent or Company, as the case
     may be, (or any successor) or such corporation owns an interest, and
     any stock which may be acquired pursuant to the exercise of options.

     For purposes of this Certificate, "Affiliated Group" shall mean one or more
chains of corporations connected through stock ownership with a common parent
corporation, but only if

          (x) the common parent owns directly stock that possesses at least
     80% of the total voting power, and has a value at least equal to 80%
     of the total value, of the stock in at least one of the other
     corporations, and

          (y) stock possessing at least 80% of the total voting power, and
     having a value at least equal to 80% of the total value, of the stock
     in each corporation (except the common parent) is owned directly by
     one or more of the other corporations.

For purposes of the preceding sentence, "stock" does not include any stock which
(a) is not entitled to vote, (b) is limited and preferred as to dividends and
does not participate in corporate growth to any significant extent, (c) has
redemption and liquidation rights which do not exceed the issue price of such
stock (except for a reasonable redemption or liquidation premium), and (d) is
not convertible into another class of stock.

       3. After the Merger, to the knowledge of the management of Company,
Company will hold at least 90% of the fair market value of the net assets and at
least 70% of the fair market value of the gross assets held by Merger Subsidiary
immediately prior to the Merger and at least 90% of the fair market value of the
net assets and at least 70% of the fair market value of the gross assets held by
Company immediately prior to the Merger. For purposes of this representation,
assets of Merger Subsidiary or Company held immediately prior to the Merger
include amounts paid or incurred by Merger Subsidiary or Company in
connection with the Merger, including amounts used to pay Company's
reorganization expenses or dissenting shareholders or to make payments to
shareholders who receive





                                  A-C-2-2
<PAGE>


                                       Annex A -- Agreement and Plan of Merger


cash or other property (including cash in lieu of fractional shares) and
all payments, redemptions and distributions (except for regular, normal
dividends, if any) made in contemplation or as part of the Merger.  Any
dispositions in contemplation or as part of the Merger of assets held by
Company prior to the Merger will be for fair market value, and the proceeds
thereof will be retained by the Company.

       4. The Company has no plan or intention to issue additional shares of its
stock that would result in Parent losing Control of the Company. For purposes of
this Certificate, "Control" with respect to a corporation shall mean ownership
of at least 80% of the total combined voting power of all classes of stock
entitled to vote and at least 80% of the total number of shares of each other
class of stock of the corporation.

       5. In the Merger, to the knowledge of the management of Company, Merger
Subsidiary will have no liabilities assumed by the Company and will not transfer
to Company any assets subject to liabilities.

       6. No assets of Company have been sold, transferred or otherwise disposed
of which would prevent Parent from continuing the historic business of Company
or from using a significant portion of Company's historic business assets in a
business following the merger, and Company intends to continue its historic
business or use a significant portion of its historic business assets in a
business.

       7. Except as specified below, Parent, Merger Subsidiary, Company and the
Company shareholders each will bear its or their own expenses, if any, incurred
in connection with or as part of the Merger or related transactions. However, to
the extent any expenses related to the Merger are to be funded directly or
indirectly by a party other than the incurring party, such expenses are solely
and directly related to the Merger, and do not include expenses incurred for
investment or estate planning advice, or expenses incurred by an individual
shareholder or group of shareholders for legal, accounting or investment advice
or counsel relating to the merger. Company has not paid or will not pay,
directly or indirectly, any expenses incurred by any shareholder of Company in
connection with or as part of the Merger or any related transactions; provided
that all liability for transfer taxes (except for stamp duties and stamp duty
reserve taxes to be paid by Parent in connection with the issuance and creation
of Parent Stock or Parent Preferred Stock in the Merger) incurred by the holders
of Company Stock or Series B Preferred Stock will be paid by Company or the
Company shareholders and in no event by Parent. Company has not agreed to
assume, nor will it directly or indirectly assume, any other expense or other
liability, whether fixed or contingent, of any holder of Company Stock or Series
B Preferred Stock.

       8. There is no intercorporate indebtedness existing between Parent and
Company or between Merger Subsidiary and Company that was issued, acquired or
will be settled at a discount.

       9. Company has no authorized stock other than common stock par value
$1.00 per share, and preferred stock, par value $1.00 per share. At the date
hereof, the only capital stock of Company issued and outstanding is Company
Stock and Series B Preferred Stock.

      10. In the Merger, Company Stock and Series B Preferred Stock representing
Control of Company will be exchanged solely for voting stock of Parent other
than cash in lieu of fractional shares. For purposes of this representation,
stock of Company exchanged for cash or other property originating with Parent,
if any, will be treated as outstanding stock of Company acquired by Parent at
the Effective Time. The payment of cash in lieu of fractional shares of Parent
stock to holders of Company Stock is solely for the purpose of avoiding the
expense and inconvenience to Parent of issuing fractional shares and does not
represent separately bargained for consideration. To the best knowledge of the
management of Company, the total cash consideration that will be paid in the
Merger to holders of Company Stock instead of issuing fractional shares of
Parent Stock will not exceed one percent of the total consideration that
will be issued to the holders of Company Stock in the Merger.  To the best
knowledge of the management of Company, the fractional share interest of
each Company shareholder will be aggregated, and no






                                  A-C-2-3
<PAGE>


Annex A -- Agreement and Plan of Merger


Company shareholder is intended to receive cash in an amount greater than
the value of one full share of Parent Stock.

      11. There exist no options, warrants, convertible securities,
equity-linked securities or other rights to acquire Company Stock or Series B
Preferred Stock (whether settled in stock or cash) other than rights pursuant to
the Company Rights, the Series B Preferred Stock, the Option Agreement, the
Company Awards and employee stock options and employee stock purchase plans in
existence as of the date of the Agreement (all as referred to in Section 3.05 of
the Agreement), and even if such rights were exercised or converted, it would
not affect the acquisition or retention of Control of Company. All such rights
will terminate at the Effective Time.

      12. To the knowledge of the management of Company, in the Merger, no
liabilities of shareholders of Company will be assumed by Parent, and Parent
will not assume any liabilities relating to any Company Stock or Series B
Preferred Stock acquired by Parent in the Merger. Furthermore, to the knowledge
of the management of Company, there is no plan or intention for Parent to assume
any liabilities of Company.

      13. The Series B Preferred Stock is the only class of stock of Company
that grants its holders dissenters' rights. In the event that any holders of
Series B Preferred Stock of Company do not vote in favor of the Merger and
perfect their right to appraisal and payment, any amounts paid to such holders
in an appraisal proceeding will be paid by Company out of its own funds. No
funds will be supplied for such payments, directly or indirectly, by Parent, nor
will Parent directly or indirectly reimburse Company for any such payments.

      14. Company is not a regulated investment company, a real estate
investment trust, or a corporation fifty percent (50%) or more of the value of
whose assets are stock and securities and eighty percent (80%) or more of the
value of whose total assets are assets held for investment (each, an "Investment
Company"). For purposes of this representation, in making the 50% and 80%
determinations under the preceding sentence, (i) stock and securities in any
subsidiary corporation shall be disregarded and the parent corporation shall be
deemed to own its ratable share of the subsidiary's assets, and (ii) a
corporation shall be considered a subsidiary if the parent owns 50% or more of
the combined voting power of all classes of stock entitled to vote or 50% or
more of the total value of shares of all classes of stock outstanding. In
determining total assets there shall be excluded cash and cash items (including
receivables), government securities, and assets acquired (through incurring
indebtedness or otherwise) for purposes of ceasing to be an Investment Company.

      15. None of the employee compensation received or to be received by any
shareholder-employees of Company is or will be separate consideration for, or
allocable to, any of their shares of Company Stock or Series B Preferred Stock
to be surrendered in the Merger. None of the shares of Parent Stock or Parent
Preferred Stock to be received by any shareholder-employee of Company in the
Merger is or will be separate consideration for, or allocable to, any
employment, consulting or similar arrangement. Any compensation paid or to be
paid to any shareholder of Company who will be an employee of or perform
advisory services for Parent, Company, or any affiliate thereof after the
Merger, will be determined by bargaining at arm's length.

      16. Since the date of the Agreement, except for the issuance of Company
Stock pursuant to the rights described in paragraph 11 hereof, Company has not
issued any additional shares of Company Stock.

      17. No holders of Company Stock have dissenters' rights with respect to
the Merger under applicable laws.

      18. Prior to and in connection with the Merger no Company Stock or Series
B Preferred Stock has been (i) redeemed by Company, (ii) acquired by a Related
Person with respect to Company (except that for the purposes of this
representation, clause (i) of the definition of Related Person shall not
apply) with consideration other than stock of Company or Parent or (iii)
the subject of any extraordinary distribution by Company.

                                       Annex A -- Agreement and Plan of Merger


     19. Except as disclosed in the Company's Schedule of Exceptions, Company
has not redeemed any of its stock, made any distributions with respect to its
stock, or disposed of any of its assets in contemplation or as part of the
Merger, excluding for purposes of this representation regular, normal dividends
and Company Stock acquired in the ordinary course of business in connection with
employee incentive and benefit programs, or other programs or arrangements in
existence on the date hereof.

      20. The Merger is being effected for bona fide business reasons and will
be carried out strictly in accordance with the Agreement, and as described in
the Proxy Statement, and none of the material terms and conditions therein has
been or will be waived or modified.

      21. The Agreement and the documents described in the Agreement, the Proxy
Statement and the Form S-4 represent the entire understanding between or among
(i) Parent and its subsidiaries and (ii) Company and its subsidiaries and, to
the best knowledge of the management of Company, between or among such entities
and the affiliates and shareholders of Parent and Company with respect to the
Merger and there are no other written or oral agreements regarding the Merger
other than those expressly referred to in the Agreement, the Proxy Statement and
the Form S-4.

      22. The fair market value of the assets of Company will exceed the sum of
its liabilities, plus the amount of liabilities, if any, to which those assets
are subject.

      23. Company will not be under the jurisdiction of a federal or state court
in a Title 11 case or in a receivership, foreclosure or similar proceeding.

      24. Except for cash in lieu of fractional shares, Parent will acquire the
Company Stock and the Series B Preferred Stock solely in exchange for voting
shares of Parent Stock and Parent Preferred Stock. For purposes of this
representation, stock of Company redeemed for cash or other property furnished
by Parent will be considered as acquired by Parent.

      25. None of Parent, Merger Subsidiary or, after the Merger, Company will
take any position on any Federal, state, or local income or franchise tax
return, or take any other tax reporting position, that is inconsistent with the
treatment of the Merger as a tax-free reorganization or any of the foregoing
representations, unless otherwise required by a decision by the Tax Court or a
judgment, decree, or other order by any court of competent jurisdiction, which
has become final, or by applicable state or local income or franchise tax law.

Meagher & Flom LLP rely, without further inquiry, on this Certificate in
rendering their opinions as to certain United States Federal income tax
consequences of the Merger, and we will promptly and timely inform them if,
after signing this Certificate, we have reason to believe that any of the
facts described herein or in the Proxy Statement or any of the
representations made in this Certificate are or have become untrue,
incorrect or incomplete in any respect.

                          STOCK OPTION AGREEMENT

     STOCK OPTION AGREEMENT dated as of December 1, 1998 (the "Agreement")
between Exxon Corporation, a New Jersey corporation ("Exxon"), and Mobil
Corporation, a Delaware corporation ("Mobil").

                           W I T N E S S E T H :

     WHEREAS, Exxon and Mobil are simultaneously with the execution and delivery
of this Agreement entering into an Agreement and Plan of Merger (the "Merger
Agreement") pursuant to which, among other things, Merger Subsidiary will merge
with and into Mobil on the terms and subject to the conditions stated therein;
and

     WHEREAS, in order to induce Exxon to enter into the Merger Agreement, Mobil
has granted to Exxon the Stock Option (as hereinafter defined), on the terms and
conditions set forth herein;

     NOW, THEREFORE, in consideration of the mutual covenants and agreements set
forth herein and in the Merger Agreement, and for other good and valuable
consideration, the adequacy of which is hereby acknowledged, the parties hereto
agree as follows:

     SECTION 1.  Definitions.  Capitalized terms used and not defined
herein have the respective meanings ascribed to them in the Merger
Agreement.

     SECTION 2. Grant of Stock Option. Mobil hereby grants to Exxon an
irrevocable option (the "Stock Option") to purchase, on the terms and subject to
the conditions hereof, for $95.96 per share (the "Exercise Price") in cash up to
136,500,000 fully paid and non-assessable shares (the "Option Shares") of
Mobil's common stock, $1.00 par value per share (the "Common Stock"). The
Exercise Price and number of Option Shares shall be subject to adjustment as
provided in Section 6 below. Notwithstanding the foregoing, if at any time that
this Stock Option is exercisable pursuant to the terms and conditions of this
Agreement an Acquisition Proposal has theretofore been made for a per Share
value (such value to be determined as of the close of the market on the trading
day immediately prior to the date of the Stock Exercise Notice or Cash Exercise
Notice, as applicable) below the Exercise Price, then Exxon's Exercise Price as
to 1,000 Option Shares (as such 1,000 shares may be adjusted pursuant to Section
6) will be adjusted to be 90% of such per Share value (it being understood that
such adjusted Exercise Price will not apply as to any other Option Shares).

     SECTION 3. Exercise of Stock Option. (a) Exxon may, subject to the
provisions of this Section, exercise the Stock Option, in whole or in part, at
any time or from time to time, after the occurrence of a Trigger Event and prior
to the Termination Date. "Termination Date" shall mean the earliest of (i) the
Effective Time of the Merger, (ii) 90 days after the date full payment is made
by Mobil to Exxon under Section 10.04(b) of the Merger Agreement or (iii) one
day after the date of the termination of the Merger Agreement so long as, in the
case of this clause (iii), no Trigger Event has occurred or could still occur
under Section 10.04(b) of the Merger Agreement. Subject to the proviso in the
last sentence of Section 3(c), notwithstanding the occurrence of the Termination
Date, Exxon shall be entitled to purchase Option Shares pursuant to any exercise
of the Stock Option, on the terms and subject to the conditions hereof, to the
extent Exxon exercised the Stock Option prior to the occurrence of the
Termination Date.

     (b) Exxon may purchase Option Shares pursuant to the Stock Option only if
all of the following conditions are satisfied: (i) no preliminary or permanent
injunction or other order issued by any federal or state court of competent
jurisdiction in the United States shall be in effect prohibiting delivery of the
Option Shares, (ii) any applicable waiting period under the HSR Act shall have
expired or been terminated, and (iii) any prior notification to or approval of
any other regulatory authority in the U.S. or elsewhere required in connection
with such purchase shall have been made or obtained other than those which if
not made or obtained would not reasonably be expected to result in a significant
detriment to Mobil and its Subsidiaries, taken as a whole.

Annex B -- Stock Option Agreement


     (c) If Exxon shall be entitled to and wishes to exercise the Stock Option,
it shall do so by giving Mobil written notice (the "Stock Exercise Notice") to
such effect, specifying the number of Option Shares to be purchased and a place
and closing date not earlier than three business days nor later than 10 business
days from the date of such Stock Exercise Notice. If the closing cannot be
consummated on such date because any condition to the purchase of Option Shares
has not been satisfied or as a result of any restriction arising under any
applicable law or regulation, the closing shall occur five days (or such earlier
time as Exxon may specify) after satisfaction of all such conditions and the
cessation of all such restrictions; provided that in no event shall the closing
of the purchase be postponed by more than nine months after the Termination Date
as a result of this clause (c).

     (d) So long as the Stock Option is exercisable pursuant to the terms of
Section 3(a) hereof, Exxon may elect, in lieu of exercising the Stock Option as
provided in Section 3(c) hereof, to send a written notice to Mobil (the "Cash
Exercise Notice") specifying a date not later than 20 business days and not
earlier than 10 business days following the date such notice is given on which
date Mobil shall pay to Exxon in exchange for the cancellation of the relevant
portion of the Stock Option an amount in cash equal to the Spread (as
hereinafter defined) multiplied by all or such portion of the Option Shares
subject to the Stock Option as Exxon shall specify. As used herein "Spread"
shall mean the excess, if any, over the Exercise Price of the higher of (x) if
applicable, the highest price per share of Common Stock paid or proposed to be
paid by any Person pursuant to any Acquisition Proposal (the "Alternative
Exercise Price") or (y) the average of the closing price of the shares of Common
Stock on the NYSE at the end of the regular session, as reported on the
Consolidated Tape, Network A (the "Closing Price") for the five consecutive
trading days ending on and including the trading date immediately preceding the
date of the Cash Exercise Notice. If the Alternative Exercise Price includes any
property other than cash, the Alternative Exercise Price shall be the sum of (i)
the fixed cash amount, if any, included in the Alternative Exercise Price plus
(ii) the fair market value of such other property. If such other property
consists of securities with an existing public trading market, the average of
the closing prices (or the average of the closing bid and asked prices if
closing prices are unavailable) for such securities in their principal public
trading market on the five trading days ending five days prior to the date of
the Cash Exercise Notice shall be deemed to equal the fair market value of such
property. If such other property consists of something other than cash or
securities with an existing public trading market and, as of the payment date
for the Spread, agreement on the value of such other property has not been
reached, the Alternative Exercise Price shall be deemed to equal such Closing
Price. Upon exercise of its right pursuant to this Section 3(d) and the receipt
by Exxon of the applicable cash amount with respect to the Option Shares or the
applicable portion thereof, the obligations of Mobil to deliver Option Shares
pursuant to Section 3(e) shall be terminated with respect to the number of
Option Shares for which Exxon shall have elected to be paid the Spread. The
Spread shall be appropriately adjusted, if applicable, to give effect to Section
6.

     (e) (i) At any closing pursuant to Section 3(c) hereof, Exxon shall make
payment to Mobil of the aggregate purchase price for the Option Shares to be
purchased and Mobil shall deliver to Exxon a certificate representing the
purchased Option Shares, registered in the name of Exxon or its designee and
(ii) at any closing pursuant to Section 3(d) hereof, Mobil will deliver to Exxon
cash in an amount determined pursuant to Section 3(d) hereof. Any payment made
by Exxon to Mobil, or by Mobil to Exxon, pursuant to this Agreement shall be
made by certified or official bank check or by wire transfer of federal funds to
a bank designated by the party receiving such funds.

     (f) Certificates for Common Stock delivered at the closing described in
Section 3(c) hereof shall be endorsed with a restrictive legend that shall read
substantially as follows:

     "The transfer of the shares represented by this certificate is subject to
resale restrictions arising under the Securities Act of 1933, as amended."

     It is understood and agreed that the above legend shall be removed by
delivery of substitute certificate(s) without such reference (i) if Exxon shall
have delivered to Mobil a copy of a no-action letter from the staff of the
Securities and Exchange Commission, or a written opinion of counsel, in
form and substance reasonably satisfactory to Mobil,

<PAGE>


                                             Annex B -- Stock Option Agreement


to the effect that such legend is not required for purposes of, or resale
may be effected pursuant to an exemption from registration under, the 1933
Act or (ii) in connection with any sale registered under the 1933 Act.  In
addition, such certificates shall bear any other legend as may be required
by applicable law.

     SECTION 4.  Representations and Warranties of Mobil.  Mobil hereby
represents and warrants to Exxon as follows:

     (a) Mobil is a corporation duly incorporated, validly existing and in good
standing under the laws of the State of Delaware. The execution, delivery and
performance by Mobil of this Agreement and the consummation of the transactions
contemplated hereby (i) are within Mobil's corporate powers, (ii) have been duly
authorized by all necessary corporate action, (iii) require no action by or in
respect of, or filing with, any governmental body, agency or official, except
for any filings required to be made under the HSR Act, the EC Merger Regulation,
the Canadian Act and the Exchange Act, (iv) do not contravene, or constitute a
violation of, any provision of applicable law or regulation or of the
certificate of incorporation or by-laws of Mobil or of any judgment, injunction,
order or decree binding upon Mobil or any of its Subsidiaries, (v) do not and
will not constitute a default under or give rise to a right of termination,
cancellation or acceleration of any right or obligation of Mobil or any of its
Subsidiaries or to a loss of any benefit to which Mobil or any of its
Subsidiaries is entitled under any provision of any agreement, contract or other
instrument binding upon Mobil or any of its Subsidiaries or any license,
franchise, permit or other similar authorization held by Mobil or any of its
Subsidiaries, and (vi) do not and will not result in the creation or imposition
of any Lien on any asset of Mobil or any of its Subsidiaries, except for such
contraventions, conflicts or violations referred to in clause (iv) or defaults,
rights of termination, cancellation or acceleration, or losses or Liens referred
to in clauses (v) and (vi) that would not, individually or in the aggregate,
have a Material Adverse Effect on Mobil. This Agreement has been duly executed
and delivered by Mobil and constitutes a valid and binding agreement of Mobil.

     (b) Mobil has taken all necessary corporate action to authorize and reserve
and to permit it to issue, and at all times from the date hereof until such time
as the obligation to deliver Option Shares upon the exercise of the Stock Option
terminates, will have reserved for issuance upon any exercise of the Stock
Option, the number of Option Shares subject to the Stock Option (less the number
of Option Shares previously issued upon any partial exercise of the Stock
Option). All of the Option Shares to be issued pursuant to the Stock Option have
been duly authorized and, upon issuance and delivery thereof pursuant to this
Agreement, will be duly authorized, validly issued, fully paid and
nonassessable, and shall be delivered free and clear of all claims, liens,
charges, encumbrances and security interests (other than those created by this
Agreement). Option Shares issued upon exercise of the Stock Option will not be
subject to any preemptive or similar rights. The Board of Directors of Mobil has
resolved to, and Mobil promptly after the execution hereof will, take all
necessary action to render the Company Rights Agreement inapplicable to the
grant or exercise of the Stock Option and the transactions contemplated hereby.

     (c) The Board of Directors of Mobil has taken the necessary action to make
inapplicable the application of Section 203 of the Delaware Law, or any other
applicable antitakeover statute or similar statute or regulation and the
supermajority voting provisions of Article 6 of Mobil's certificate of
incorporation to the acquisition of the Option Shares pursuant to this
Agreement.

     SECTION 5. Representations and Warranties of Exxon. Exxon hereby represents
and warrants to Mobil as follows: Exxon is a corporation duly incorporated,
validly existing and in good standing under the laws of the State of New Jersey.
The execution, delivery and performance by Exxon of this Agreement and the
consummation of the transactions contemplated hereby (i) are within Exxon's
corporate powers and (ii) have been duly authorized by all necessary corporate
action. The Option Shares acquired by Exxon upon the exercise of the Stock
Options will not be, and the Stock Option is not being, acquired by Exxon with
the intention of making a public distribution thereof. Neither the Stock Option
nor the Option Shares acquired upon exercise of the Stock Option will be sold or
otherwise disposed of by Exxon except in compliance with the 1933 Act.
This agreement has been duly executed and delivered by Exxon and
constitutes a valid and binding agreement of Exxon.

Annex B -- Stock Option Agreement


     SECTION 6. Adjustment upon Changes in Capitalization or Merger. (a) In the
event of any change in the outstanding shares of Common Stock by reason of a
stock dividend, stock split, split-up, merger, consolidation, recapitalization,
combination, conversion, exchange of shares, extraordinary or liquidating
dividend or similar transaction which would have the effect of diluting Exxon's
rights hereunder, the type and number of shares or securities purchasable upon
the exercise of the Stock Option and the Exercise Price shall be adjusted
appropriately, and proper provision will be made in the agreements governing
such transaction, so that Exxon will receive upon exercise of the Stock Option
the number and class of shares or other securities or property that Exxon would
have received in respect of the Option Shares had the Stock Option been
exercised immediately prior to such event or the record date therefor, as
applicable. In no event shall the number of shares of Common Stock subject to
the Stock Option exceed 14.9% of the number of shares of Common Stock issued and
outstanding at the time of exercise (treating as outstanding for this purpose
the shares subject to the Stock Option).

     (b) Without limiting the foregoing, whenever the number of Option Shares
purchasable upon exercise of the Stock Option is adjusted as provided in this
Section 6, the Exercise Price shall be adjusted by multiplying the Exercise
Price by a fraction, the numerator of which is equal to the number of Option
Shares purchasable prior to the adjustment and the denominator of which is equal
to the number of Option Shares purchasable after the adjustment.

     (c) Without limiting the parties' relative rights and obligations under the
Merger Agreement, in the event that Mobil enters into an agreement (i) to
consolidate with or merge into any person, other than Exxon or one of its
subsidiaries, and Mobil will not be the continuing or surviving corporation in
such consolidation or merger, (ii) to permit any person, other than Exxon or one
of its subsidiaries, to merge into Mobil and Mobil will be the continuing or
surviving corporation, but in connection with such merger, the shares of Common
Stock outstanding immediately prior to the consummation of such merger will be
changed into or exchanged for stock or other securities of Mobil or any other
person or cash or any other property, or the shares of Common Stock outstanding
immediately prior to the consummation of such merger will, after such merger,
represent less than 50% of the outstanding voting securities of the merged
company, or (iii) to sell or otherwise transfer all or substantially all of its
assets to any person, other than Exxon or one of its subsidiaries, then, and in
each such case, the agreement governing such transaction will make proper
provision so that the Stock Option will, upon the consummation of any such
transaction and upon the terms and conditions set forth herein, be converted
into, or exchanged for, an option with identical terms appropriately adjusted to
acquire the number and class of shares or other securities or property that
Exxon would have received in respect of Option Shares had the Stock Option been
exercised immediately prior to such consolidation, merger, sale or transfer or
the record date therefor, as applicable, and will make any other necessary
adjustments. Mobil shall take such steps in connection with such consolidation,
merger, liquidation or other such transaction as may be reasonably necessary to
assure that the provisions hereof shall thereafter apply as nearly as possible
to any securities or property thereafter deliverable upon exercise of the Stock
Option.

     SECTION 7. Further Assurances; Remedies. (a) Mobil agrees to maintain, free
from preemptive rights, sufficient authorized but unissued or treasury shares of
Common Stock so that the Stock Option may be fully exercised without additional
authorization of Common Stock after giving effect to all other options,
warrants, convertible securities and other rights of third parties to purchase
shares of Common Stock from Mobil, and to issue the appropriate number of shares
of Common Stock pursuant to the terms of this Agreement.

     (b) Mobil agrees not to avoid or seek to avoid (whether by charter
amendment or through reorganization, consolidation, merger, issuance of rights,
dissolution or sale of assets, or by any other voluntary act) the observance or
performance of any of the covenants, agreements or conditions to be observed or
performed hereunder by Mobil.

     (c) Mobil agrees that promptly after the date hereof it shall take all
actions as may from time to time be required (including (i) complying with all
applicable premerger notification, reporting and waiting period requirements
under the HSR Act and (ii) in the event that prior notification to or approval
of any other regulatory authority in the U.S. or elsewhere is necessary before
the Stock Option may be exercised, cooperating with Exxon in preparing and
processing

<PAGE>


                                             Annex B -- Stock Option Agreement


the required notices or applications) in order to permit Exxon to exercise
the Stock Option and purchase Option Shares pursuant to such exercise and
to take all reasonable action necessary to protect the rights of Exxon
against dilution.

     (d) The parties agree that Exxon would be irreparably damaged if for any
reason Mobil failed to issue any of the Option Shares (or other securities or
property deliverable pursuant to Section 6 hereof) upon exercise of the Stock
Option or to perform any of its other obligations under this Agreement, and that
Exxon would not have an adequate remedy at law for money damages in such event.
Accordingly, Exxon shall be entitled to specific performance and injunctive and
other equitable relief to enforce the performance of this Agreement by Mobil.
Accordingly, if Exxon should institute an action or proceeding seeking specific
enforcement of the provisions hereof, Mobil hereby waives the claim or defense
that Exxon has an adequate remedy at law and hereby agrees not to assert in any
such action or proceeding the claim or defense that such a remedy at law exists.
Mobil further agrees to waive any requirements for the securing or posting of
any bond in connection with obtaining any such equitable relief. This provision
is without prejudice to any other rights that Exxon may have against Mobil for
any failure to perform its obligations under this Agreement.

     SECTION 8. Listing of Option Shares. Promptly after the date hereof, and
from time to time thereafter if necessary, Mobil will apply to list all of the
Option Shares subject to the Stock Option on the New York Stock Exchange and
will use its reasonable best efforts to obtain approval of such listing as soon
as practicable.

     SECTION 9. Registration of the Option Shares. (a) If Exxon requests Mobil
in writing, within two years of the exercise of the Stock Option, to register
under the 1933 Act any of the Option Shares purchased by Exxon hereunder, Mobil
will use its reasonable best efforts to cause the offering of the Option Shares
so specified in such request to be registered as soon as practicable so as to
permit the sale or other distribution by Exxon of the Option Shares specified in
its request (and to keep such registration in effect for a period of at least 90
days), and in connection therewith Mobil will prepare and file as promptly as
reasonably possible (but in no event later than 60 days from receipt of Exxon's
request) a registration statement under the 1933 Act to effect such registration
on an appropriate form, which would permit the sale of the Option Shares by
Exxon in accordance with the plan of disposition specified by Exxon in its
request. Mobil shall not be obligated to make effective more than two
registration statements pursuant to the foregoing sentence; provided, however,
that Mobil may postpone the filing of a registration statement relating to a
registration request by Exxon under this Section 9 for a period of time (not in
excess of 90 days) if in Mobil's reasonable, good faith judgment such filing
would require the disclosure of material information that Mobil has a bonafide
business purpose for preserving as confidential (but in no event shall Mobil
exercise such postponement right more than once in any twelve-month period).

     (b) Mobil shall notify Exxon in writing not less than 10 days prior to
filing a registration statement under the 1933 Act (other than a filing on Form
S-4 or S-8 or any successor form) with respect to any Common Stock. If Exxon
wishes to have any portion of its Option Shares included in such registration
statement, it shall advise Mobil in writing to that effect within two business
days following receipt of such notice, and Mobil will thereupon include the
number of Option Shares indicated by Exxon under such Registration Statement;
provided that if the managing underwriter(s) of the offering pursuant to such
registration statement advise Mobil that in their opinion the number of shares
of Common Stock requested to be included in such registration exceeds the number
which can be sold in such offering, Mobil shall only include in such
registration such number or dollar amount of Option Shares which, in the good
faith opinion of the managing underwriter(s), can be sold without materially and
adversely affecting such offering.

     (c) All expenses relating to or in connection with any registration
contemplated under this Section 9 and the transactions contemplated thereby
(including all filing, printing, reasonable professional and other fees and
expenses relating thereto) will be at Mobil's expense except for underwriting
discounts or commissions and brokers' fees. Mobil and Exxon agree to enter into
a customary underwriting agreement with underwriters upon such terms and
conditions as are customarily contained in underwriting agreements with respect
to secondary distributions. Mobil shall indemnify Exxon, its officers,
directors, agents, other controlling persons and any underwriters retained by
Exxon in connection


                                    B-5
<PAGE>


Annex B -- Stock Option Agreement


with such sale of such Option Shares in the customary way, and shall agree
to customary contribution provisions with such persons, with respect to
claims, damages, losses and liabilities (and any expenses relating thereto)
arising (or to which Exxon, its officers, directors, agents, other
controlling persons or underwriters may be subject) in connection with any
such offer or sale under the federal securities laws or otherwise, except
for information furnished in writing by Exxon or its underwriters to Mobil.
Exxon and its underwriters, respectively, shall indemnify Mobil to the same
extent with respect to information furnished in writing to Mobil by Exxon
and such underwriters, respectively.

     SECTION 10.  Miscellaneous.  (a)  Extension of Exercise Periods.  The
periods for exercise of certain rights under Sections 3(d) and 3(e) hereof
shall be extended in each such case at the request of Exxon to the extent
necessary to avoid liability by Exxon under Section 16(b) of the Exchange
Act by reason of such exercise.

     (b) Amendments; Entire Agreement. This Agreement may not be modified,
amended, altered or supplemented, except upon the execution and delivery of a
written agreement executed by the parties hereto. This Agreement, together with
the Merger Agreement (including any exhibits and schedules thereto), contains
the entire agreement between the parties hereto with respect to the subject
matter hereof and supersedes all prior and contemporaneous agreements and
understandings, oral or written, with respect to such transactions.

required by applicable law or any listing agreement with any national
securities exchange, may be issued prior to such consultation, if the party
making such release or statement has used its reasonable efforts to consult
with the other party.

     SECTION 11. Profit Limitation. (a) Notwithstanding any other provision of
this Agreement or the Merger Agreement, in no event shall Exxon's Total Profit
(as defined below) exceed $2,000,000,000 (the "Maximum Amount") and, if it
otherwise would exceed such Maximum Amount, Exxon at its sole election may (i)
pay cash to Mobil, (ii) deliver to Mobil for cancellation Option Shares
previously purchased by Exxon, or (iii) any combination thereof, so that Exxon's
actually realized Total Profit (as defined below) shall not exceed the Maximum
Amount after taking into account the foregoing actions.

     (b) Notwithstanding any other provision of this Agreement, the Stock Option
may not be exercised for a number of Option Shares as would, as of the date of
the Stock Exercise Notice, result in a Notional Total Profit (as defined below)
of more than the Maximum Amount and, if exercise of the Stock Option otherwise
would result in the Notional Total Profit exceeding such amount, Exxon, at its
discretion, may (in addition to any of the actions specified in Section 11(a)
above) increase the Exercise Price for that number of Option Shares set forth in
the Stock Exercise Notice so that the Notional Total Profit shall not exceed the
Maximum Amount; provided, that nothing in this sentence shall restrict any
exercise of the Stock Option permitted hereby on any subsequent date at the
Exercise Price set forth in Section 3(d) hereof.

     (c) As used herein, the term "Total Profit" shall mean the aggregate amount
(before taxes) of the following: (i) the cash amount actually received by Exxon
pursuant to Section 10.04(b) of the Merger Agreement less any repayment by Exxon
to Mobil pursuant to Section 11(a)(i) hereof, (ii) (x) the net cash amounts or
the fair market value of any property received by Exxon pursuant to the sale of
Option Shares (or of any other securities into or for which such Option Shares
are converted or exchanged), less (y) Exxon's purchase price for such Option
Shares (or other securities) plus (iii) the aggregate amounts received by Exxon
pursuant to Section 3(d).

     (d) As used herein, the term "Notional Total Profit" with respect to any
number of Option Shares as to which Exxon may propose to exercise the Stock
Option shall be the Total Profit determined as of the date of the Stock Exercise
Notice assuming that the Stock Option was exercised on such date for such number
of Option Shares and assuming that such Option Shares, together with all other
Option Shares previously acquired upon exercise of the Stock Option and held by
Exxon and its affiliates as of such date, were sold for cash at the Closing
Price on the preceding trading day (less customary brokerage commissions).

     The Board of Directors
     Exxon Corporation
     5959 Las Colinas Boulevard
     Irving, Texas  75039-2298

     Ladies and Gentlemen:

          You have requested our opinion as to the fairness, from a
     financial point of view, to Exxon Corporation (the "Acquiror") of the
     consideration proposed to be paid by the Acquiror in connection with
     the proposed merger (the "Merger") of Lion Acquisition Subsidiary
     Corporation, a wholly-owned subsidiary of the Acquiror ("Merger
     Subsidiary"), with and into Mobil Corporation (the "Company").
     Pursuant to the Agreement and Plan of Merger, dated as of December 1,
     1998 (together with its exhibits, the "Agreement"), among the
     Acquiror, Merger Subsidiary and the Company, Merger Subsidiary will
     merge with and into the Company, the Company will continue as the
     surviving corporation and become a wholly-owned subsidiary of the
     Acquiror, and (i) each share of common stock, par value $1.00 per
     share, of the Company outstanding immediately prior to the effective
     time of the Merger (other than shares held by the Company as treasury
     stock (excluding certain such shares held in "Rabbi trusts") or owned
     by the Acquiror or any subsidiary of the Acquiror) shall be converted
     into the right to receive 1.32015 shares of fully-paid and non-
     assessable common stock, without par value, of the Acquiror (the
     "Acquiror's Common Stock") and (ii) each share of Series B ESOP
     Convertible Preferred Stock, par value $1.00 per share, of the Company
     shall be converted into the right to receive one fully-paid and non-
     assessable share of a new series of preferred stock to be issued by
     the Acquiror having terms and conditions that are, to the extent
     possible, identical to the terms and conditions of the Series B ESOP
     Convertible Preferred Stock immediately prior to the effective time of
     the Merger.

          In arriving at our opinion, we have reviewed (i) the Agreement;
     (ii) the Joint Proxy Statement/Prospectus of the Acquiror and the
     Company relating to the Merger (the "Proxy Statement);  (iii) certain
     publicly available information concerning the business of the Company
     and of certain other companies engaged in businesses comparable to
     those of the Company, and the reported market prices for certain other
     companies' securities deemed comparable;  (iv) publicly available
     terms of certain transactions involving companies comparable to the
     Company and the consideration received for such companies;  (v)
     current and historical market prices of the common stock of the
     Company and the Acquiror;  (vi) the audited financial statements of
     the Acquiror and the

<PAGE>

Annex C -- Opinion of J.P. Morgan Securities Inc.                     JPMORGAN


     Company for the fiscal year ended December 31, 1998;  (vii) certain
     internal financial analyses of potential synergies that may be
     realized from the Merger prepared by the Acquiror and the Company and
     their respective managements;  (viii) certain presentations made by
     the Acquiror and the Company in 1998 to equity analysts regarding the
     performance of their respective businesses; and (ix) the terms of
     other business combinations that we deemed relevant.

          In addition, we have participated in discussions with certain
     members of the management of the Acquiror and the Company with respect
     to certain aspects of the Merger, the past and current business
     operations of the Acquiror and the Company, the financial condition
     and future prospects and operations of the Acquiror and the Company,
     and certain other matters we believed necessary or appropriate to our
     inquiry.  We have reviewed such other financial studies and analyses
     and considered such other information as we deemed appropriate for the
     purposes of this opinion.

          In giving our opinion, we have relied upon and assumed, without
     independent verification, the accuracy and completeness of all
     information that was publicly available or was furnished to us by the
     Acquiror and the Company or otherwise reviewed by us, and we have not
     assumed any responsibility or liability therefor.  We have not
     conducted any valuation or appraisal of any assets or liabilities, nor
     have any such valuations or appraisals been provided to us.  In
     relying on financial analyses provided to us of potential synergies
     that may be realized from the Merger, we have assumed that they have
     been reasonably prepared based on assumptions reflecting the best
     currently available estimates and judgments by management as to such
     potential synergies.  We have also assumed that the Merger will have
     the tax consequences and pooling-of-interests accounting treatment
     described in the Agreement and the Proxy Statement, and that the
     transactions contemplated by the Agreement will be consummated as
     described in the Agreement and the Proxy Statement.  We have relied as
     to all legal matters relevant to rendering our opinion upon the advice
     of counsel.

          Our opinion is necessarily based on economic, market and other
     conditions as in effect on, and the information made available to us
     as of, the date hereof.  It should be understood that subsequent
     developments may affect this opinion and that we do not have any
     obligation to update, revise, or reaffirm this opinion.  We are
     expressing no opinion herein as to the price at which the Acquiror's
     Common Stock will trade at any future time.

          We have acted as financial advisor to the Acquiror with respect
     to the proposed Merger and will receive a fee from the Acquiror for
     our services.  We will also receive all additional fee if the proposed
     Merger is consummated.  As you are aware, in the past we have provided
     financial advisory services to a subsidiary of the Acquiror.  Please
     be advised that in the past we have provided financial advisory and
     other services to the Company.  In the ordinary course of their
     businesses, our affiliates may actively trade the debt and equity
     securities of the Acquiror or the Company for their own account or for
     the accounts of customers and, accordingly, they may at any time hold
     long or short positions in such securities.

          On the basis of and subject to the foregoing, it is our opinion
     as of the date hereof that the consideration to be paid by the
     Acquiror in the proposed Merger is fair, from a financial point of
     view, to the Acquiror.

          This letter is provided to the Board of Directors of the Acquiror
     in connection with and for the purposes of its evaluation of the
     Merger.  This opinion does not constitute a recommendation to any
     stockholder of the Acquiror as to how such stockholder should vote
     with respect to the Merger.

     Very truly yours,

Board of Directors
Mobil Corporation
3225 Gallows Road
Fairfax, Virginia 22037-0001

Ladies and Gentlemen:

You have requested our opinion as to the fairness from a financial point of
view to the holders (other than Exxon Corporation ("Acquiror") or any of its
subsidiaries or affiliates) (the "Holders") of the outstanding shares of
Common Stock, par value $1.00 per share (the "Shares"), of Mobil Corporation
(the "Company") of the exchange ratio of 1.32015 shares of Common Stock,
without par value ("Acquiror Shares"), of Acquiror to be received for each
Share (the "Exchange Ratio") pursuant to the Agreement and Plan of Merger,
dated as of December 1, 1998, among Acquiror, Lion Acquisition Subsidiary
Corporation, a wholly-owned subsidiary of Acquiror, and the Company (the
"Agreement").

Goldman, Sachs & Co., as part of its investment banking business, is
continually engaged in the valuation of businesses and their securities in
connection with mergers and acquisitions, negotiated underwritings,
competitive biddings, secondary distributions of listed and unlisted
securities, private placements and valuations for estate, corporate and other
purposes.  We are familiar with the Company having provided certain investment
banking services to the Company from time to time, including having acted as
dealer on the Company's commercial paper program; having acted as agent on the
Company's stock repurchase program and medium term note program; and having
acted as lead-managing underwriter of a public offering of Mobil
Corporation Pass Through Certificates, Series 1997-A in May 1997.  We also
have provided certain investment banking services to Acquiror from time to
time and may provide investment banking services to Acquiror in the future.
Goldman, Sachs & Co. provides a full range of financial advisory and
securities services and, in the course of its normal trading activities,
may from time to time effect transactions and hold securities, including
derivative securities, of the Company or Acquiror for its own account and
for the accounts of customers.  As of March 29, 1999, Goldman, Sachs & Co.
accumulated a net short position of 299,546 Shares.  As of March 29, 1999,
Goldman, Sachs & Co. accumulated a net short position of 71,699 Acquiror
Shares, a net short position of options to purchase 150,000 Acquiror Shares
and a net long position of warrants to purchase 4,175,795 Acquiror Shares.

In connection with this opinion, we have reviewed, among other things, the
Agreement; the Stock Option Agreement dated as of December 1, 1998 between
Acquiror and the Company; the Joint Proxy Statement/Prospectus relating to
the Annual Meetings of Stockholders of the Company and the

Acquiror to be held in connection with the Agreement;  Annual Reports to
Stockholders and Annual Reports on Form 10-K of the Company and Acquiror
for the five years ended December 31, 1998; certain interim reports to
stockholders and Quarterly Reports on Form 10-Q of the Company and
Acquiror; certain other communications from the Company and Acquiror to
their respective stockholders; certain internal financial analyses and
forecasts for the Company prepared by its management; and certain cost
savings and operating synergies projected by the managements of the Company
and Acquiror to result from the transaction contemplated by the Agreement
(the "Synergies").  We also have held discussions with members of the
senior management of the Company regarding the strategic rationale for, and
the potential benefits of, the transaction contemplated by the Agreement
and the Company's past and current business operations, financial condition
and future prospects.  We reviewed forecasts regarding selected measures of
future operating and financial performance of Acquiror in summary form
prepared by management of the Company based on their discussions with
management of Acquiror.  Internal financial analyses and forecasts prepared
by Acquiror were not otherwise made available for our review.  In addition,
we have reviewed the reported price and trading activity for the Shares and
Acquiror Shares, compared certain financial and stock market information
for the Company and Acquiror with similar information for certain other
companies the securities of which are publicly traded, reviewed the
financial terms of certain recent business combinations and performed such
other studies and analyses as we considered appropriate.

We have relied upon the accuracy and completeness of all of the financial and
other information reviewed by us and have assumed such accuracy and
completeness for purposes of rendering this opinion.  In that regard, we have
assumed with your consent that the Synergies have been reasonably prepared on
a basis reflecting the best currently available estimates and judgments of the
Company and Acquiror.  We have assumed with your consent that the transaction
contemplated by the Agreement will be accounted for as a pooling-of-interests
under generally accepted accounting principles.  We also have assumed that all
material governmental, regulatory or other consents and approvals necessary
for the consummation of the transaction contemplated by the Agreement will be
obtained without any meaningful adverse effect on the Company or Acquiror.  In
addition, we have not made an independent evaluation or appraisal of the
assets and liabilities of the Company or Acquiror or any of their subsidiaries
and we have not been furnished with any such evaluation or appraisal.  Our
advisory services and the opinion expressed herein are provided for the
information and assistance of the Board of Directors of the Company in
connection with its consideration of the transaction contemplated by the
Agreement and such opinion does not constitute a recommendation as to how any
holder of Shares should vote with respect to such transaction.

Based upon and subject to the foregoing and based upon such other matters as
we consider relevant, it is our opinion that as of the date hereof the
Exchange Ratio pursuant to the Agreement is fair from a financial point of
view to the Holders of Shares.

                                  PART II

                  INFORMATION NOT REQUIRED IN PROSPECTUS

Item 20.  Indemnification of Directors and Officers.

     Indemnification under Exxon By-Laws and New Jersey Law. Exxon Corporation
does not have any provisions for indemnification of directors or officers in its
charter. Article Ten of the By-laws of Exxon provides that Exxon shall indemnify
to the full extent permitted by law any director or officer made or threatened
to be made a party to any legal action by reason of the fact that such person is
or was a director, officer, employee or other corporate agent of Exxon or any
subsidiary or served any other enterprise at the request of Exxon against
expenses, judgments, fines, penalties, excise taxes and amounts paid in
settlement. The New Jersey Business Corporation Act provides for the
indemnification of directors and officers under certain conditions.

     Exxon D&O Insurance. The directors and officers of Exxon are insured under
a policy of directors' and officers' liability insurance issued by a
wholly-owned subsidiary of Exxon.

     Merger Agreement Provisions Relating To Mobil Directors and Officers. The
merger agreement provides that for seven years after the closing , Exxon will
indemnify and hold harmless each person who was a director or officer of Mobil
at or prior to the date of the merger agreement from their acts or omissions in
those capacities occurring prior to the closing to the extent provided under
Mobil's charter and by-laws as in effect on December 1, 1998.

     The merger agreement also provides that for a period of seven years after
the closing, Exxon will provide directors' and officers' liability insurance
covering acts or omissions occurring prior to closing by each person currently
covered by Mobil's officers' and directors' liability insurance policy. This
insurance policy must be no less favorable than the Mobil policy in effect on
December 1, 1998, except that Exxon will only be obligated to pay up to 300% of
the annual premium paid by Mobil for such insurance as of December 1, 1998.
Exxon may provide this coverage through a policy underwritten by a wholly-owned
subsidiary of Exxon.

Item 22.  Undertakings.

      (a)  The undersigned registrant hereby undertakes:

      (1) To file, during any period in which offers or sales are being made, a
   post-effective amendment to this registration statement:

                        (i) To include any prospectus required by Section
          10(a)(3) of the Securities Act of 1933;

                       (ii) To reflect in the prospectus any facts or events
          arising after the effective date of the registration statement (or the
          most recent post-effective amendment thereof) which, individually or
          in the aggregate, represent a fundamental change in the information
          set forth in the registration statement. Notwithstanding the
          foregoing, any increase or decrease in volume of securities offered
          (if the total dollar value of securities offered would not exceed that
          which was registered) and any deviation from the low or high end of
          the estimated maximum offering range may be reflected in the form of
          prospectus filed with the Commission pursuant to Rule 424(b) if, in
          the aggregate, the changes in volume and price represent no more than
          20 percent change in the maximum aggregate offering price set forth in
          the "Calculation of Registration Fee" table in the effective
          registration statement;

                      (iii) To include any material information with respect to
          the plan of distribution not previously disclosed in the registration
          statement or any material change to such information in the
          registration statement.

      (2) That, for the purpose of determining any liability under the
   Securities Act of 1933, each such post-effective amendment shall be deemed
   to be a new registration statement relating to the securities offered
   therein, and the offering of such securities at that time shall be deemed
   to be the initial bona fide offering thereof.

      (3) To remove from registration by means of a post-effective amendment any
   of the securities being registered which remain unsold at the termination
   of the offering.

      (4) That prior to any public reoffering of the securities registered
   hereunder through use of a prospectus which is a part of this registration
   statement, by any person or party who is deemed to be an underwriter within
   the meaning of Rule 145(c), such reoffering prospectus will contain the
   information called for by the applicable registration form with respect to
   reofferings by persons who may be deemed underwriters, in addition to the
   information called for by the other items of the applicable form.

      (5) That every prospectus (i) that is filed pursuant to paragraph (4)
   immediately preceding, or (ii) that purports to meet the requirements of
   Section 10(a)(3) of the Securities Act of 1933 and is used in connection
   with an offering of securities subject to Rule 415, will be filed as a part
   of an amendment to the registration statement and will not be used until
   such amendment is effective, and that, for purposes of determining any
   liability under the Securities Act of 1933, each such post-effective
   amendment shall be deemed to be a new registration statement relating to
   the securities offered therein, and the offering of such securities at that
   time shall be deemed to be the initial bona fide offering thereof.

      (6) That, for purposes of determining any liability under the Securities
   Act of 1933, each filing of the registrant's annual report pursuant to
   Section 13(a) or 15(d) of the Securities Exchange Act of 1934 (and, where
   applicable, each filing of an employee benefit plan's annual report
   pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is
   incorporated by reference in the registration statement shall be deemed to
   be a new registration statement relating to the securities offered therein,
   and the offering of such securities at that time shall be deemed to be the
   initial bona fide offering thereof.

      (7) To respond to requests for information that is incorporated by
   reference into the Joint Proxy Statement/Prospectus pursuant to Item 4,
   10(b), 11 or 13 of this form, within one business day of receipt of such
   request, and to send the incorporated documents by first class mail or
   other equally prompt means. This includes


                                  S4-II-3

<PAGE>


   information contained in documents filed subsequent to the effective
   date of the registration statement through the date of responding to the
   request.

      (8) To supply by means of a post-effective amendment all information
   concerning a transaction, and the company being acquired involved therein,
   that was not the subject of and included in the registration statement when
   it became effective.

      (b) Insofar as indemnification for liabilities arising under the
Securities Act of 1933 may be permitted to directors, officers and controlling
persons of the registrant pursuant to the foregoing provisions, or otherwise,
the registrant has been advised that in the opinion of the Securities and
Exchange Commission such indemnification is against public policy as expressed
in the Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
registrant of expenses incurred or paid by a director, officer or controlling
person of the registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Act and will
be governed by the final adjudication of such issue.

                                  S4-II-4

                               [Exxon Letterhead]

Securities and Exchange Commission
450 Fifth Street, N. W.
Washington, D. C.  20549

Ladies and Gentlemen:

     As General Counsel of Exxon Corporation, a New Jersey corporation
("Exxon"), I am familiar with its Restated Certificate of Incorporation and
By-laws, as amended to date. I have examined its corporate proceedings in
connection with the preparation and filing under the Securities Act of 1933, as
amended (the "Securities Act"), of a registration statement on Form S-4 of even
date herewith (the "Registration Statement"), covering shares (the "Shares") of
Exxon's common stock, no par value, to be issued in connection with the merger
of Mobil Corporation ("Mobil") and Lion Acquisition Subsidiary Corporation, a
wholly-owned subsidiary of Exxon, pursuant to the terms of the Agreement and
Plan of Merger dated as of December 1, 1998, among Exxon, Mobil, and Lion
Acquisition Subsidiary Corporation (the "Merger Agreement").

     I have also examined originals or copies, certified or otherwise
authenticated to my satisfaction, of all such documents and records and
conducted such other investigations of fact and law as I have deemed necessary
as a basis for this opinion. As to certain questions of fact, I have relied upon
statements of officers of Exxon and others.

     In rendering this opinion I have assumed that prior to the issuance of any
of the Shares (i) the Registration Statement, as then amended, will have become
effective under the Securities Act, (ii) the shareholders of Exxon will have
approved the Merger Agreement and the issuance of the Shares, (iii) the
shareholders of Mobil will have approved and adopted the Merger Agreement, and
(iv) the transactions contemplated by the Merger Agreement are consummated.

     On the basis of the foregoing, I am of the opinion that the Shares, when
issued and delivered in accordance with the terms and conditions of the Merger
Agreement, will be duly authorized, validly issued, fully paid, and
non-assessable.

     This opinion relates solely to the federal laws of the United States and
the corporate law of the State of New Jersey.

     I consent to the filing of this opinion as an exhibit to the Registration
Statement. In addition, I consent to the reference to me under the caption
"Legal Matters" in the Joint Proxy Statement/Prospectus constituting a part of
the Registration Statement. In giving this consent, I do not admit that I am in
the category of persons whose consent is required under Section 7 of the
Securities Act.

                                                Very truly yours,

                                                /s/ Charles W. Matthews

                    [Davis Polk & Wardwell letterhead]

Re:   Registration Statement on Form S-4

Exxon Corporation
5959 Las Colinas Blvd.
Irving, Texas 75039-2298

Ladies and Gentlemen:

         We have acted as counsel for Exxon Corporation ("Exxon"), a New
Jersey corporation, in connection with (i) the Merger, as defined and
described in the Agreement and Plan of Merger dated as of December 1, 1998
(the "Merger Agreement") among Mobil Corporation ("Mobil"), a Delaware
corporation, Lion Acquisition Subsidiary Corporation ("Merger Subsidiary"),
a Delaware corporation and newly formed, wholly owned subsidiary of Exxon,
and Exxon and (ii) the preparation and filing of the related Registration
Statement on Form S-4 (the "Registration Statement"), which includes the
Proxy Statement/Prospectus (the "Proxy Statement/Prospectus"), filed with
the Securities and Exchange Commission (the "Commission") under the
Securities Act of 1933, as amended (the "Securities Act") and the
Securities Exchange Act of 1934, as amended.  Unless otherwise indicated,
each capitalized term used herein has the meaning ascribed to it in the
Merger Agreement.

         In connection with this opinion, we have examined the Merger
Agreement, the Proxy Statement/Prospectus and such other documents as we
have deemed necessary or appropriate in order to enable us to render our
opinion.  For purposes of this opinion, we have assumed (i) the validity
and accuracy of the documents that we have examined, (ii) that the Merger
would be consummated in the manner described in Merger Agreement and the
Proxy Statement/Prospectus, and that the representations made and the
representations to be made by Exxon (together with Merger Subsidiary) and
Mobil pursuant to Section 8.02(e) of the Merger Agreement are and will be
accurate and complete.  In rendering our opinion, we have considered the
applicable provisions of the Internal Revenue Code of 1986, as amended (the
"Code"), Treasury Department regulations promulgated thereunder, pertinent
judicial authorities, interpretive rulings of the IRS and such other
authorities as we have considered relevant.  It should be noted that

<PAGE>


Exxon Corporation                       2                        April 2, 1999


statutes, regulations, judicial decisions and administrative
interpretations are subject to change at any time (possibly with
retroactive effect).  A change in the authorities or the inaccuracy of any
of the documents or assumptions on which our opinion is based could affect
our conclusions.

         Based upon the foregoing, in our opinion, the Merger will be
treated for Federal income tax purposes as a reorganization within the
meaning of Section 368(a) of the Code and Exxon, Mobil and Merger
Subsidiary will each be a party to that reorganization within the meaning
of Section 368(b) of the Code, and accordingly, for U.S. federal income tax
purposes:

         (i)   holders of Exxon stock will not recognize any gain or loss as
               a result of the Merger;

         (ii)  except in respect of cash received instead of fractional
               shares of Exxon Mobil common stock, holders of shares of
               Mobil stock will (1) not recognize any gain or loss as a
               result of the exchange of their shares of Mobil stock for
               Exxon Mobil stock, (2) have a tax basis in the Exxon Mobil
               stock received in the merger equal to the tax basis of the
               Mobil stock surrendered in the Merger, and (3) have a
               holding period with respect to the Exxon Mobil stock
               received in the Merger that includes the holding period of
               the Mobil stock surrendered in the Merger;

         (iii) a holder of Mobil common stock will be required to recognize
               gain or loss with respect to cash received instead of a
               fractional share of Exxon Mobil common stock, measured by
               the difference between the amount of cash received and the
               portion of the tax basis of the holder's shares of Mobil
               common stock allocable to the fractional share, which gain
               or loss will be capital gain or loss if the holder of Mobil
               common stock holds such stock as a capital asset within the
               meaning of Section 1221 of the Code and will be long-term
               capital gain or loss if the share of Mobil common stock
               exchanged for the fractional share was held for more than
               one year at the Effective Time;

               Mobil shareholders are primarily liable, if any, may be

         (v)  none of Exxon, Mobil or Merger Subsidiary will recognize gain
               or loss as a result of the Merger.

does not address any non-income tax or any foreign, state or local tax
consequences of the Merger.

Mobil Corporation
3225 Gallows Road
Fairfax, Virginia  22307

Ladies and Gentlemen:

     We have acted as counsel to Mobil Corporation, a Delaware corporation
("Mobil"), in connection with (i) the Merger, as defined and described in the
Agreement and Plan of Merger, dated as of December 1, 1998 (the "Merger
Agreement"), among Mobil, Exxon Corporation, a New Jersey corporation ("Exxon")
and Lion Acquisition Subsidiary Corporation, a Delaware corporation and a
newly-formed, wholly-owned subsidiary of Exxon ("Merger Subsidiary"), and (ii)
the preparation and filing of the Registration Statement on Form S-4 (the
"Registration Statement"), which includes the Proxy Statement/Prospectus (the
"Proxy Statement/Prospectus"), filed with the Securities and Exchange Commission
(the "Commission") under the Securities Act of 1933, as amended (the "Securities
Act") and the Securities Exchange Act of 1934, as amended. Unless otherwise
indicated, each capitalized term used herein has the meaning ascribed to it in
the Merger Agreement.

     In connection with this opinion, we have examined the Merger Agreement, the
Proxy Statement/Prospectus and such other documents and corporate records as we
have deemed necessary or appropriate in order to enable us to render the opinion
below. For purposes of this opinion, we have assumed (i) the validity and
accuracy of the documents and corporate records that we have examined, and the
facts and representations concerning the Merger that have come to our attention
during our engagement, and (ii) that the Merger will be consummated in the
manner described in the Merger Agreement and the Proxy Statement/Prospectus.

     Subject to the assumptions set forth above, the representations made to us
by Mobil, Exxon and Merger Subsidiary in their respective letters dated the date
hereof and the assumptions and qualifications set forth in the discussion in the
Proxy Statement/Prospectus under the heading "Material Federal Income Tax
Consequences of the Merger", in our opinion, the Merger will be treated for
federal income tax purposes as a reorganization qualifying under the provisions
of Section 368(a) of the Code and each of Exxon, Merger Subsidiary and Mobil
will be a party to the reorganization within the meaning of Section 368(b) of
the Code, and accordingly, for U.S. federal income tax purposes:

        (i) holders of Exxon stock will not recognize any gain or loss as a
     result of the Merger;

        (ii) except in respect of cash received instead of fractional shares of
     Exxon Mobil common stock, holders of shares of Mobil stock will (1) not
     recognize any gain or loss as a result of the exchange of their shares of
     Mobil stock for Exxon Mobil stock, (2) have a tax basis in the Exxon Mobil
     stock received in the Merger equal to the tax basis of the Mobil stock
     surrendered in the Merger, and (3) have a holding period with respect to
     the Exxon Mobil stock received in the Merger that includes the holding
     period of the Mobil stock surrendered in the Merger;

        (iii) a holder of Mobil common stock will be required to recognize gain
     or loss with respect to cash received instead of a fractional share of
     Exxon Mobil common stock, measured by the difference between the amount of
     cash received and the portion of the tax basis of the holder's shares of
     Mobil common stock allocable to the fractional share, which gain or loss
     will be capital gain or loss if the holder of Mobil common stock holds such
     stock as a capital asset within the meaning of Section 1221 of the Code and
     will be long-term capital gain or loss


<PAGE>



     if the share of Mobil common stock exchanged for the fractional share was
     held for more than one year at the Effective Time;

        (iv) although the matter is not free from doubt (because of the
     absence of legislative, judicial or other authority directly on
     point), Mobil's payment of transfer taxes for which the Mobil
     shareholders are primarily liable, if any, may be taxable as a
     dividend to the Mobil shareholders; and

        (v) none of Exxon, Mobil or Merger Subsidiary will recognize gain or
     loss as a result of the Merger.

     The preceding are all of the material U.S. federal income tax
consequences of the Merger.  However, our opinion does not address U.S.
federal income tax consequences which may vary with, or are contingent
upon, a shareholder's individual circumstances.  In addition, our opinion
does not address any non-income tax or any foreign, state or local tax
consequences of the Merger.

     This opinion is delivered in accordance with the requirements of Item
601(b)(8) of Regulation S-K under the Securities Act. In rendering our opinion,
we have considered the applicable provisions of the Code, Treasury Department
regulations promulgated thereunder, pertinent judicial authorities, interpretive
rulings of the IRS and such other authorities as we have considered relevant. It
should be noted that statutes, regulations, judicial decisions and
administrative interpretations are subject to change at any time (possibly with
retroactive effect). A change in the authorities or the accuracy or completeness
of any of the information, documents, corporate records, covenants, statements,
representations or assumptions on which our opinion is based could affect our
conclusions. This opinion is expressed as of the date hereof, and we are under
no obligation to supplement or revise our opinion to reflect any changes
(including changes that have retroactive effect) (i) in applicable law or (ii)
in any information, document, corporate record, covenant, statement,
representation or assumption stated herein which becomes untrue or incorrect.

     This letter is furnished to you solely for use in connection with the
Merger, as described in the Merger Agreement and the Proxy
Statement/Prospectus, and is not to be used, circulated, quoted, or
otherwise referred to for any other purpose without our express written
permission.  In accordance with the requirements of Item 601(b)(23) of
Regulation S-K under the Securities Act, we hereby consent to the
discussion of this opinion in the Proxy Statement/Prospectus, to the filing
of this opinion as an exhibit to the Proxy Statement/Prospectus and to the
reference to our firm under the headings "THE MERGER TRANSACTION--Material
Federal Income Tax Consequences of the Merger," "THE MERGER AGREEMENT--
Conditions to the Completion of the Merger" and "LEGAL MATTERS" in the

thereunder.

Re:  Registration Statement (File No. 333-     ) of
     Mobil Corporation and Exxon Corporation

Ladies and Gentlemen:

     Reference is made to our opinion letter dated April 2, 1999 with
respect to the fairness from a financial point of view to the holders
(other than Exxon Corporation ("Exxon") or any of its subsidiaries or
affiliates (the "Holders")) of the outstanding shares of Common Stock, par
value $1.00 per share (the "Shares"), of Mobil Corporation ("Mobil") of the
exchange ratio of 1.32015 shares of Common Stock, without par value ("Exxon
Shares"), of Exxon to be received for each Share (the "Exchange Ratio")
pursuant to the Agreement and Plan of Merger, dated as of December 1, 1998,
among Exxon, Lion Acquisition Subsidiary Corporation, a wholly-owned
subsidiary of Exxon, and Mobil.

     The foregoing opinion letter is provided for the information and assistance
of the Board of Directors of Mobil in connection with its consideration of the
transaction contemplated therein and is not to be used, circulated, quoted or
otherwise referred to for any other purpose, nor is it to be filed with,
included in or referred to in whole or in part in any registration statement,
proxy statement or any other document, except in accordance with our prior
written consent. We understand that the Company has determined to include our
opinion in the above-referenced Registration Statement.

     In that regard, we hereby consent to the reference to the opinion of our
Firm under the caption(s) "Summary", "The Merger Transaction" and "Opinions of
Financial Advisors" and to the inclusion of the foregoing opinion in the Joint
Proxy Statement/Prospectus included in the above-mentioned Registration
Statement, as amended. In giving such consent, we do not thereby admit that we
come within the category of persons whose consent is required under Section 7 of
the Securities Act of 1933 or the rules and regulations of the Securities and
Exchange Commission thereunder.
