           .00163% of the Trust per $1,000 Reference Principal Amount

          THIS CERTIFIES THAT CEDE & CO., as nominee of the Depository Trust
Company, for value received, is the registered owner of a Fractional Undivided
Interest in the amount of SIXTY-ONE MILLION FOUR HUNDRED THOUSAND DOLLARS
($61,400,000) (the "Reference Principal Amount") in the Mobil Corporation 1997-C
Pass Through Trust (the "Trust") created by State Street Bank and Trust Company,
as trustee (the "Trustee"), pursuant to a Pass Through Trust Agreement, dated as
of October 4, 1996 (the "Basic Agreement"), as supplemented by the Pass Through
Trust Supplement No. 1997-C thereto dated as of December 5, 1997 (collectively,
the "Agreement"), among the Trustee, Mobil Corporation, a Delaware corporation
(the "Guarantor") and Mobil Equipment Finance Company Inc., a Delaware
corporation (the "Company"), a summary of certain of the pertinent provisions of
which is set forth below.  To the extent not otherwise defined herein, the
capitalized terms used herein have the meanings assigned to them in the
Agreement.  This Certificate is one of the duly authorized Certificates
designated as "Pass Through Certificates, Series 1997-C" (herein called the
"Certificates").  This Certificate is issued under and is subject to the terms,
provisions, and conditions of the Agreement, to which Agreement the Holder of
this Certificate by virtue of the acceptance hereof assents and by which such
Certificateholder is bound.  The property of the Trust includes certain Secured
Notes (the "Trust Property").  Each issue of the Secured Notes is issued in
respect of a Vessel leased to the Company all of whose obligations are
guaranteed by the Guarantor.

 
                                       2

          The Certificates represent fractional undivided interests in the Trust
and the Trust Property, and have no rights, benefits or interest in respect of
any other separate trust established pursuant to the terms of the Basic
Agreement for any other series of certificates issued pursuant thereto.

          Subject to and in accordance with the terms of the Agreement, from
funds then available to the Trustee, there will be distributed on each January 2
and July 2 (a "Regular Distribution Date"), commencing on July 2, 2000, to the
Person in whose name this Certificate is registered at the close of business on
the 15th day preceding the applicable Regular Distribution Date, an amount in
respect of the Scheduled Payments on the Secured Notes due on such Regular
Distribution Date, the receipt of which has been confirmed by the Trustee, equal
to the product of the percentage interest in the Trust evidenced by this
Certificate and an amount equal to the sum of such Scheduled Payments.  Subject
to and in accordance with the terms of the Agreement, in the event that Special
Payments on the Secured Notes are received by the Trustee, from funds then
available to the Trustee, there shall be distributed on the applicable Special
Distribution Date, to the Person in whose name this Certificate is registered at
the close of business on the 15th day preceding such Special Distribution Date,
an amount in respect of such Special Payments on the Secured Notes, the receipt
of which has been confirmed by the Trustee, equal to the product of the
percentage interest in the Trust evidenced by this Certificate and an amount
equal to the sum of such Special Payments so received.  If a Regular
Distribution Date or Special Distribution Date is not a Business Day,
distribution shall be made on the immediately following Business Day with the
same force and effect as if made on such Regular Distribution Date or Special
Distribution Date and no interest shall accrue during the intervening period.
The Trustee shall mail notice of each Special Payment and the Special
Distribution Date therefor to the Certificateholder of this Certificate.

          Distributions on this Certificate will be made by the Trustee by check
mailed to the Person entitled thereto, without the presentation or surrender of
this Certificate or the making of any notation hereon.  Except as otherwise
provided in the Agreement and notwithstanding the above, the final distribution
on this Certificate will be made after notice mailed by the Trustee of the
pendency of such distribution and only upon presentation and surrender of this
Certificate at the office or agency of the Trustee specified in such notice.

          The Certificates do not represent an obligation of, or an obligation
guaranteed by, or an interest in, the Guarantor, the Company or the Trustee or
any affiliate thereof.  The Certificates are limited in right of payment, all as
more specifically set forth herein on the face hereof and in the Agreement.  All
payments or distributions made to Certificateholders under the Agreement shall
be made only from the Trust Property and only to the extent that the Trustee
shall have sufficient income or proceeds from the Trust Property to make such
payments in accordance with the terms of the Agreement.  Each Holder of this
Certificate, by its acceptance hereof, agrees that it will look solely to the
income and proceeds from the Trust Property to the extent available for
distribution to such Certificateholder as provided in the Agreement.  This
Certificate does not purport to

 
                                       3
 
summarize the Agreement and reference is made to the Agreement for information
with respect to the interests, rights, benefits, obligations, proceeds and
duties evidenced hereby.  A copy of the Agreement may be examined during normal
business hours at the principal office of the Trustee, and at such other places,
if any, designated by the Trustee, by any Certificateholder upon request.

          The Agreement permits, with certain exceptions therein provided, the
amendment thereof and the modification of the rights and obligations of the
Guarantor, the Company and the rights of the Certificateholders under the
Agreement at any time with the consent of the Holders holding Certificates
evidencing Fractional Undivided Interests aggregating not less than a majority
in interest in the Trust.  Any such consent by the Holder of this Certificate
shall be conclusive and binding on such Certificateholder and upon all future
Holders of this Certificate and of any Certificate issued upon the transfer
hereof or in exchange hereof or in lieu hereof whether or not notation of such
consent is made upon this Certificate.  The Agreement also permits the amendment
thereof, in certain limited circumstances, without the consent of the
Certificateholders of any of the Certificates.

          As provided in the Agreement and subject to certain limitations
therein set forth, the transfer of this Certificate is registrable in the
Register upon surrender of this Certificate for registration of transfer at the
offices or agencies maintained by the Trustee in its capacity as Registrar, or
by any successor Registrar, duly endorsed or accompanied by a written instrument
of transfer in form satisfactory to the Trustee and the Registrar duly executed
by the Holder hereof or such Certificateholder's attorney duly authorized in
writing, and thereupon one or more new Certificates of authorized denominations
evidencing the same aggregate Fractional Undivided Interest in the Trust will be
issued to the designated transferee or transferees.

          The Certificates are issuable only as registered Certificates without
coupons in minimum denominations of $1,000 Fractional Undivided Interest and
integral multiples thereof except that one Certificate may be in a denomination
of less than  $1,000.  As provided in the Agreement and subject to certain
limitations therein set forth, the Certificates are exchangeable for new
Certificates of authorized denominations evidencing the same aggregate
Fractional Undivided Interest in the Trust, as requested by the
Certificateholder surrendering the same.

          No service charge will be made for any such registration of transfer
or exchange, but the Trustee shall require payment of a sum sufficient to cover
any tax or governmental charge payable in connection therewith.

          The Guarantor, the Company, the Trustee, the Registrar and any agent
of the Trustee or the Registrar may treat the person in whose name this
Certificate is registered on the Register as the owner hereof for all purposes,
and neither the Guarantor, the Company, the Trustee, the Registrar nor any such
agent shall be affected by any notice to the contrary.

 
                                      4 

          The obligations and responsibilities created by the Agreement and the
Trust created thereby shall terminate upon the distribution to
Certificateholders of all amounts required to be distributed to them pursuant to
the Agreement and the disposition of all property held as part of the Trust
Property.


          THE AGREEMENT AND THIS CERTIFICATE SHALL BE GOVERNED BY AND CONSTRUED
IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.

          Reference is hereby made to the further provisions of this Certificate
set forth on the reverse hereof, which further provisions shall for all purposes
have the same effect as if set forth at this place.

          Unless the certificate of authentication hereon has been executed by
the Trustee by manual signature, this Certificate shall not be entitled to any
benefit under the Agreement or be valid for any purpose.

 
        IN WITNESS WHEREOF, the Trustee has caused this Certificate to be duly
executed.
