     1. The shares of common stock of Mobil Corporation (the "Issuer") covered
by this report are purchasable by Exxon Corporation ("Exxon") upon exercise of
an option (the "Option") granted to Exxon pursuant to the Stock Option Agreement
dated as of December 1, 1998 between the Issuer and Exxon (the "Stock Option
Agreement"), and described in Item 4 of this statement. Prior to the exercise of
the Option, Exxon is not entitled to any rights as a shareholder of the Issuer
as to the shares covered by the Option. The number of shares of common stock of
the Issuer purchasable by Exxon under the Option, which is initially set to
equal 136,500,000 shares, is subject to adjustment in certain circumstances,
provided that the aggregate number of shares purchasable by Exxon upon exercise
of the Option at the time of its exercise (together with prior purchases under
the Option) may not exceed 14.9% of the total outstanding shares of common stock
of the Issuer immediately prior to the time of such exercise (treating as
outstanding for this purpose the shares of common stock subject to the Option).
The Option may only be exercised upon the happening of certain events, none of
which has occurred as of the date hereof. Prior to such occurrence, Exxon
expressly disclaims beneficial ownership of the shares of common stock of the
Issuer which are purchasable by Exxon upon exercise of the Option.

     2. The number of shares indicated represents approximately 14.9% of the
total outstanding shares of common stock of the Issuer as of November 27, 1998
(treating as outstanding for this purpose the shares of common stock subject to
the Option).

     3. The number of shares indicated does not include shares which
may be held by any of Exxon's employee benefits plans.






                                     3 of 9



Item 1.  Security and Issuer

     This Schedule 13D relates to the common stock, par value $1.00 per share
(the "Common Stock," an individual share of which is a "Share"), of Mobil
Corporation, a Delaware corporation (the "Issuer"). The principal executive
offices of the Issuer are located at 3225 Gallows Road, Fairfax, Virginia
22307-0001.

Item 2.  Identity and Background

     This Schedule 13D is filed by Exxon Corporation ("Exxon"), a New Jersey
corporation. 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's principal offices are located at 5959 Las Colinas Boulevard,
Irving, Texas 75039-2298.

     During the last five years neither Exxon nor, to the best of Exxon's
knowledge, any of its executive officers or directors has been convicted in a
criminal proceeding (excluding traffic violations or similar misdemeanors) or
has been a party to a civil proceeding of a judicial or administrative body of
competent jurisdiction resulting in a judgment, decree or final order enjoining
future violations of, or prohibiting or mandating activities subject to, federal
or state securities laws, or finding any violation with respect to such laws.

     All executive officers and directors of Exxon are citizens of the United
States except for Rene Dahan and S.R. McGill, who are citizens of The
Netherlands and Australia, respectively. The name, business address and present
principal occupation (including the name and address of the corporation or
organization in which such employment is conducted) of each executive officer
and director is set forth in Schedule A to this Schedule 13D.

Item 3.  Source and Amount of Funds or Other Consideration

     This statement relates to an option granted to Exxon by the Issuer to
purchase shares of Common Stock from the Issuer as described in Item 4 below
(the "Option"). The Option entitles Exxon to purchase up to 136,500,000 Shares
(the "Option Shares") under the circumstances specified in the Stock Option
Agreement dated as of December 1, 1998 between Exxon and the Issuer (the "Stock
Option Agreement") and as described in Item 4 below, for a purchase price of
$95.96 per Share (the "Purchase Price") (with the purchase price per share as to
1,000 Option Shares being adjustable under certain specified circumstances). The
number of Option Shares and Purchase Price are subject to adjustment in certain
circumstances, provided that the aggregate number of Shares purchasable by Exxon
upon exercise of the Option at the time of its exercise (together with prior
purchases under the Option) may not exceed 14.9% of the total outstanding shares
of Common Stock of the Issuer immediately prior to the time of such exercise
(treating as outstanding for this purpose the shares of Common Stock subject to
the Option). Reference is hereby made to the Stock Option Agreement, which is
included as Exhibit 2.2 to the Current Report on Form 8-K filed by Exxon on
December 1, 1998 (the "Form 8-K"), for the full text of its terms, including the
conditions upon which it may be exercised. The Stock Option Agreement is
incorporated herein by reference in its entirety.

     The Option was granted by the Issuer as an inducement to Exxon to enter
into the Agreement and Plan of Merger (the "Merger Agreement") dated as of
December 1, 1998 among Exxon, Lion Acquisition Subsidiary Corporation ("Merger
Subsidiary") and the Issuer. Pursuant to the Merger Agreement and subject to the
terms and conditions set forth therein (including approval by the stockholders
of Exxon and the Issuer and various regulatory agencies), Merger Subsidiary will
merge with and into the Issuer (the "Merger") with the Issuer continuing as the
surviving corporation (the "Surviving Corporation") and becoming a wholly-owned
subsidiary of Exxon, and each issued and outstanding share of Common Stock of
the Issuer (other than those shares owned by the Issuer or Exxon) will be
converted into the right to receive 1.32015 shares of common stock, no par
value, of Exxon. If the Merger is consummated, the Option will not be exercised.
No monetary consideration was paid by Exxon to the Issuer for the Option.

     If Exxon elects to exercise the Option, it currently anticipates that the
funds to pay the Purchase Price will be generated by available working capital.

                                     4 of 9


Item 4.  Purpose of Transaction

     As stated above, the Option was granted to Exxon in connection with the
execution of the Merger Agreement as an inducement to Exxon to enter into the
Merger Agreement.

     The Option shall become exercisable upon the occurrence of certain "Trigger
Events" and in the circumstances described in the Stock Option Agreement and the
Merger Agreement, none of which has occurred at the time of this filing.

     If the Merger is consummated in accordance with the terms of the Merger
Agreement, the Board of Directors of the Surviving Corporation shall consist of
the directors of Merger Subsidiary at the effective time of the Merger (the
"Effective Time") and the officers of the Surviving Corporation shall be the
officers of Issuer at the Effective Time. The certificate of incorporation of
Issuer in effect at the Effective Time shall be the certificate of incorporation
of the Surviving Corporation. The bylaws of Merger Subsidiary in effect at the
Effective Time shall be the bylaws of the Surviving Corporation.

     In the event the Merger is consummated, the Common Stock of the Issuer will
be delisted from the New York Stock Exchange and any other exchange on which it
is listed, and will become eligible for termination of registration under the
Securities Exchange Act of 1934, as amended.

     The descriptions herein of the Stock Option Agreement and the Merger
Agreement are qualified in their entirety by reference to such agreements,
copies of which were filed as Exhibits 2.2 and 2.1, respectively, to the Form
8-K and which are incorporated herein by reference in their entirety.

     Other than as described above, Exxon has no plans or proposals which relate
to, or may result in, any of the matters listed in items 4(a)-(j) of Schedule
13D.

Item 5.  Interest in Securities of the Issuer

     As a result of the issuance of the Option and upon occurrence of certain
events described in the Stock Option Agreement, Exxon may be deemed to be the
beneficial owner of 136,500,000 Shares, which would represent approximately
14.9% of the Shares outstanding after exercise of the Option (based on the
number of Shares outstanding on November 27, 1998, as set forth in the Merger
Agreement, and treating as outstanding for this purpose the Shares of Common
Stock subject to the Option). Exxon would have sole voting and dispositive power
with respect to such Shares.

     The Option Shares described herein are subject to the Option, which may
only be exercised upon the happening of certain events, none of which has
occurred as of the date hereof. Nothing contained herein shall be deemed to be
an admission by Exxon as to the beneficial ownership of any Shares, and, prior
to the occurrence of any of such events, Exxon disclaims beneficial ownership of
all Option Shares.

     Except as described herein, neither Exxon nor, to the best of Exxon's
knowledge, any other person referred to in Schedule A attached hereto,
beneficially owns or has acquired or disposed of any Shares of the Issuer during
the past 60 days.

Item 6.  Contracts, Arrangements, Understandings or Relationships with Respect
to Securities of the Issuer

     Except for the Merger Agreement and the Stock Option Agreement, none of the
persons named in Item 2 has any contracts, arrangements, understandings or
relationships (legal or otherwise) with any persons with respect to any
securities of the Issuer, including, but not limited to, transfers or voting of
any securities, finder's fees, joint ventures, loan or option arrangements, puts
or calls, guarantees of profits, division of profits or loss, or the giving or
withholding of proxies.
