                               MOBIL CORPORATION

          Up to $650,000,000 aggregate public offering price of Pass Through
       Certificates (the "Certificates") (or its equivalent (based on the
       applicable exchange rate at the time of sale) in one or more foreign
       currencies or units based on or related to currencies, including European
       Currency Units) may be offered for sale from time to time pursuant to
       this Prospectus and related Prospectus Supplements (as defined below).
       Certificates may be issued in one or more series in amounts, at prices
       and on terms to be determined at the time of the offering.  In respect of
       each offering of Certificates, a separate Mobil Pass Through Trust for
       each series of Certificates being offered (each, a "Pass Through Trust")
       will be formed pursuant to a Pass Through Trust Agreement (the "Basic
       Agreement"), among Mobil Marine Finance Company I Inc., Mobil Marine
       Finance Company II Inc., Mobil Lease Finance Company Inc., Mobil Chemical
       Finance (Texas) Inc., Mobil Chemical Finance (Louisiana) Inc., Mobil
       Petrorail Finance Inc., Mobil Transport Finance Company Inc., Mobil
       Equipment Finance Company Inc. (each, a "Lessee"), Mobil Corporation
       ("Mobil") and State Street Bank and Trust Company (the "Trustee"), as
       trustee under each Pass Through Trust, and a supplement thereto (each, a
       "Trust Supplement") relating to such Pass Through Trust to be entered
       into among one or more of the Lessees, Mobil and the Trustee.  Each
       Certificate in a series will represent a fractional undivided interest in
       the related Pass Through Trust and will have no rights, benefits or
       interests in respect
<PAGE>
 
       of any other Pass Through Trust.  The property of each Pass Through Trust
       will consist of notes (the "Secured Notes") issued on a nonrecourse basis
       by one or more owner trustees (each, an "Owner Trustee") of one or more
       separate owner trusts (each, an "Owner Trust") in connection with one or
       more separate leveraged lease transactions to finance or refinance all or
       a portion of the cost of certain real or personal property to be
       specified in a Prospectus Supplement, which property may consist of title
       to, an estate for years or a leasehold or similar interest in equipment,
       manufacturing, drilling or production facilities, marine tankers, rail
       cars, corporate aircraft (including engines), drilling platforms,
       refineries, pipelines, chemical plants, and other real or personal
       property or undivided interests therein (each such specified property,
       "Leased Property").  Each Leased Property has been or will be leased or
       chartered to a Lessee pursuant to separate lease agreements, sublease
       agreements, charters or similar agreements (each, a "Lease").  Although
       neither the Certificates nor the Secured Notes will be obligations of, or
       guaranteed by, any Lessee or Mobil, the amounts unconditionally payable
       under the Lease or Leases related to a Pass Through Trust will be at
       least sufficient to pay in full when due all payments of principal and
       interest and, except in the limited circumstances set forth in the
       applicable Prospectus Supplement, premium, if any, due in respect of the
       Secured Notes held in that Pass Through Trust.  Mobil will fully and
       unconditionally guarantee (in each case pursuant to a "Parent Guaranty")
       to the holders of Certificates from time to time the full and prompt
       payment of amounts payable by the Lessee under a related Lease when and
       as the same shall become due and payable.

          The specific terms of the particular Certificates in respect of which
       this Prospectus is being delivered will be set forth in a supplement to
       this Prospectus (each, a "Prospectus Supplement") which will be delivered
       together with this Prospectus, and which will include, where applicable,
       the specific designation, form, aggregate principal amount, initial
       public offering price and distribution dates relating to such
       Certificates, the currency in which such Certificates will be payable,
       and the use of the net proceeds from the offering of such Certificates.
       The Prospectus Supplement will also describe the Pass Through Trust or
       Pass Through Trusts relating to such Certificates, the Secured Notes to
       be purchased by such Pass Through Trust or Pass Through Trusts, each
       Leased Property relating to such Secured Notes, the leveraged lease
       transactions relating to such Secured Notes and other special terms
       relating to such Certificates.

          If so specified in a Prospectus Supplement related to an offering of
       Certificates, the Trust Property (as defined below) of a Pass Through
       Trust will consist of Secured Notes related to Leased Property which are
       subordinated in right of payment to other Secured Notes related to the
       same Leased Property.  In respect of such offering, only Secured Notes
       having the same priority of payment may be held in the same Pass Through
       Trust.  In addition, the related Prospectus Supplement may provide that
       the Trustees on behalf of the applicable Pass Through Trusts may enter
       into an intercreditor or subordination agreement establishing priorities
       among series of Certificates or that one or more payments of interest on
       the related Secured Notes of one or more series or distributions made by
       the Trustee of the related Pass Through Trust will be supported by a
       liquidity facility issued by an institution identified in the related
       Prospectus Supplement.

                                       2
<PAGE>
 
          Secured Notes may be issued in respect of one or more items of Leased
       Property.  Secured Notes in respect of a particular item of Leased
       Property may be issued in one or more series, each of which may have a
       different interest rate and different final maturity dates.  For each
       series of Certificates, the Trustee will purchase one or more Secured
       Notes issued with respect to one or more items of Leased Property such
       that all of the Secured Notes held in the related Pass Through Trust will
       have identical interest rates (in each case equal to the rate applicable
       to the Certificates issued by such Pass Through Trust), and such that the
       latest maturity date for such Secured Notes will occur on or before the
       final distribution date for such Certificates. Interest paid on the
       Secured Notes held in each Pass Through Trust will be passed through to
       the holders of the Certificates relating to such Pass Through Trust on
       the dates and at the rate per annum set forth in the Prospectus
       Supplement relating to such Certificates until the final distribution
       date for such Pass Through Trust.  Principal paid on the Secured Notes
       held in each Pass Through Trust will be passed through to the holders of
       the Certificates relating to such Pass Through Trust in scheduled amounts
       on the dates set forth in the Prospectus Supplement relating to such
       Certificates until the final distribution date for such Pass Through
       Trust.  The Secured Notes to be held in a Pass Through Trust will be
       secured by (i) an assignment of certain of the issuing Owner Trustee's
       rights as lessor or charterer under the Lease relating to the Leased
       Property to which such Secured Notes relate, including the right to
       receive rentals and certain other payments from the Lessee, (ii) an
       assignment of certain of such Owner Trustee's rights under the Parent
       Guaranty relating to such Leased Property and (iii) to the extent
       specified in the applicable Prospectus Supplement, a mortgage or other
       security interest in such Leased Property or in construction contracts or
       other agreements, collateral accounts or other security, in each case
       subject to the rights of the Lessee under the related Lease and other
       rights, if any, described in the applicable Prospectus Supplement.

          The Certificates may be sold to or through underwriters, through
       dealers or agents or directly to purchasers.  See "Plan of Distribution."
       Each Prospectus Supplement will set forth the names of any underwriters,
       dealers or agents involved in the sale of the Certificates in respect of
       which that Prospectus Supplement is being delivered, the proposed
       amounts, if any, to be purchased by underwriters and the compensation, if
       any, of such underwriters or agents. See "Plan of Distribution" for
       information concerning secondary trading of the Certificates.

          THIS PROSPECTUS MAY NOT BE USED TO CONSUMMATE SALES OF CERTIFICATES
       UNLESS ACCOMPANIED BY A PROSPECTUS SUPPLEMENT.



         THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE

                             AVAILABLE INFORMATION

          Mobil and the Lessees have filed with the Securities and Exchange
       Commission (the "Commission") a registration statement on Form S-3
       (together with any amendments thereto, the "Registration Statement")
       under the Securities and Exchange Act of 1933, as amended (the
       "Securities Act"), with respect to Certificates offered hereby.  This
       Prospectus, which constitutes a part of the Registration Statement, omits
       certain information contained in the Registration Statement as permitted
       by the rules and regulations of the Commission.  For further information
       with respect to Mobil, the Lessees or the Certificates offered hereby,
       reference is made to the Registration Statement, exhibits, financial
       statements, notes and schedules filed as part thereof, which may be
       inspected at the public reference facilities of the Commission at the
       addresses set forth below.  Statements made in this Prospectus as to the
       contents of any contract, agreement or other document referred to are not
       necessarily complete.  With respect to each such contract, agreement or
       other document filed as an exhibit to the Registration Statement,
       reference is made to the exhibit for a more complete description of the
       document or matter involved, and each such statement made herein with
       respect to such contract, agreement or document shall be deemed qualified
       in its entirety by such reference.

          Mobil is subject to the reporting requirements of the Securities
       Exchange Act of 1934, as amended (the "Exchange Act"), and in accordance
       therewith files reports and other information with the Commission.  The
       Registration Statement, as well as such reports and other information
       filed by Mobil pursuant to the Exchange Act, may be inspected and copied
       (at prescribed rates) at the public reference facilities maintained by
       the Commission at Room 1024, 450 Fifth Street, N.W., Washington, D.C.
       20549, and at the Regional Offices of the Commission at 7 World Trade
       Center, Suite 1300, New York, New York 10048 and at 500 West Madison
       Street, Suite 1400, Chicago, Illinois 60661.  The Commission also
       maintains a site on the World Wide Web at http://www.sec.gov that
       contains reports, proxy and information statements and other information
       filed electronically by Mobil.  In addition, such reports, proxy
       statements and other information may be inspected at the offices of the
       New York Stock Exchange, 20 Broad Street, New York, New York 10005, upon
       which the common stock of Mobil is traded.

          No separate financial statements of any of the Lessees have been
       included or incorporated by reference herein.  Mobil and the Lessees do
       not consider that such financial statements would be material to holders
       of the Certificates because (i) all of the voting securities of each
       Lessee will be owned, directly or indirectly, by Mobil, a reporting
       company under the Exchange Act, (ii) each of the Lessees is a newly-
       formed special purpose entity, has no independent operations and will not
       engage in any activity other than leasing Leased Property and (iii) the
       obligations of each of the Lessees are fully and unconditionally
       guaranteed by Mobil as and to the extent described herein.  See "The
       Lessees," "Description of the Certificates," and "Parent Guaranties."

                            FORMATION OF THE TRUSTS
    
          In respect of each offering of Certificates, a separate Pass Through
       Trust for each series of Certificates being offered will be formed
       pursuant to the Basic Agreement and a Trust Supplement to be entered into
       among Mobil, the Trustee and one or more Lessees (each Lessee that is
       liable under one or more related Leases, an "Applicable Lessee").
       Following the execution and delivery of a Trust Supplement, the Trustee,
       on behalf of the related Pass Through Trust, will purchase the Secured
       Notes to be held in such Pass Through Trust having an interest rate (or,
       in the case of Secured Notes with a zero coupon, accrual rate) equal to 
       the interest rate (or accrual rate) applicable to the Certificates 
       evidencing interests in such Pass Through Trust. The maturity date of the
       Secured Notes acquired by a Pass Through Trust will occur not later than
       the final scheduled distribution date applicable to the Certificates
       evidencing an interest in such Pass Through Trust. The Trustee will
       distribute all payments of principal, premium, if any, and interest
       received by it as holder of such Secured Notes to the holders of
       Certificates evidencing an interest in the Pass Through Trust in which
       such Secured Notes are held. See "Description of the Certificates."    

                    OUTLINE OF THE LEVERAGED LEASE STRUCTURE

          Unless otherwise specified in the applicable Prospectus Supplement,
       the Certificates offered pursuant to any Prospectus Supplement will be
       issued to facilitate the acquisition by one or more Owner Trustees, each
       acting not in its individual capacity (except as expressly set forth in
       such Prospectus Supplement) but solely as trustee under a separate trust
       agreement (each, an "Owner Trust Agreement") for one or more equity
       investors (each, an "Owner Participant"), of certain items of Leased
       Property. Owner Participants may include affiliates of Mobil.  Not later
       than the delivery date of the applicable Leased Property to an Owner
       Trustee, such Owner Trustee will lease or charter such Leased Property to
       a Lessee pursuant to a separate Lease.  Such Lessee may initially
       sublease or subcharter such Leased Property to an affiliate of Mobil.

          The Owner Trustees will obtain a portion of the funding for the Leased
       Property from the equity investments of the related Owner Participants,
       which will be the beneficiaries of the related Owner Trusts, and will
       obtain the remainder of the funding from the issuance on a non-recourse
       basis of the Secured Notes to be held in the related Pass Through Trusts
       and, to the extent set forth in the applicable Prospectus Supplement,
       additional debt secured by such Leased Property or other sources. The
       Secured Notes to be held in the Pass Through Trusts will be acquired by
       the Trustee with the proceeds from the sale of Certificates.

          Secured Notes relating to a particular Leased Property will be issued
       under a separate indenture and security agreement or a similar agreement
       (each, an "Indenture") with respect to such Leased Property.  Each
       Indenture will be entered into by and among a financial institution (the
       "Corporate Indenture Trustee") and, where required by applicable law, an
       individual who may be an officer or employee of the Corporate Indenture
       Trustee (the "Individual Indenture Trustee"), as trustees thereunder (the
       Corporate Indenture Trustee and the Individual Indenture Trustee, in such
       capacities, the "Indenture Trustees"), and the issuing Owner Trustee.  No

                                       8
<PAGE>
 
       Owner Trustee or Owner Participant will be personally liable for any
       amount payable under the related Indenture or the Secured Notes issued
       thereunder.

          The Secured Notes issued under each Indenture and held in each Pass
       Through Trust will be secured by (i) an assignment of certain of the
       related Owner Trustee's rights as lessor or charterer under the Lease
       with respect to the applicable Leased Property, including the right to
       receive certain rentals and other payments from the Applicable Lessee,
       (ii) an assignment of certain of such Owner Trustee's rights under the
       Parent Guaranty relating to such Leased Property, and (iii) to the
       extent specified in the applicable Prospectus Supplement, a mortgage or
       other security interest in such Leased Property, or in construction
       contracts or other agreements, collateral accounts or other security, in
       each case subject to the rights of the Applicable Lessee under the
       related Lease and other rights, if any, described in the applicable
       Prospectus Supplement.  (Such security with respect to each Indenture
       shall be referred to as the "Indenture Estate.")  Unless otherwise set
       forth in the applicable Prospectus Supplement, the Secured Notes issued
       under an Indenture will not be secured by any of the Leased Properties
       securing the Secured Notes issued under any other Indenture (including
       any other Leased Properties acquired by the related Owner Trustee) and
       will not be cross-defaulted with Secured Notes issued under any other
       Indenture (including any other Indenture entered into by such Owner
       Trustee).

          The rents and other amounts payable by the Applicable Lessee under the
       related Lease will be sufficient to pay in full when due all payments of
       principal and interest  and, except in the limited circumstances set
       forth in the applicable Prospectus Supplement, premium, if any, due in
       respect of the Secured Notes issued under the Indenture.  The Secured
       Notes will not be recourse obligations of any Owner Participant or
       issuing Owner Trustee, but will be payable solely from the rents or
       charter hire and other amounts payable under the Lease of the Leased
       Property securing such Secured Notes and amounts realized from the
       exercise of the Indenture Trustee's remedies under the Indenture against
       the related Indenture Estate.  Pursuant to a Parent Guaranty, Mobil will
       fully and unconditionally guarantee the full and prompt payments payable
       by the Applicable Lessee under the related Lease when and as the same
       shall become due and payable.  See "Description of the Secured Notes."

                                USE OF PROCEEDS

          The Certificates offered pursuant to this Prospectus and a related
       Prospectus Supplement will be issued in order to facilitate the financing
       or refinancing of all or a portion of the cost of certain Leased Property
       specified in such Prospectus Supplement.  The proceeds from the sale of
       Certificates in respect of such Leased Property is not expected to exceed
       90% of the value of such Leased Property at the time of financing or
       refinancing, which may be established by appraisal or by reference to its
       original cost.  Except as set forth in a Prospectus Supplement for a
       specific offering of Certificates, the proceeds from the sale of the
       Certificates will be used by the Trustee or Trustees on behalf of the
       applicable Pass Through Trust or Pass Through Trusts to purchase Secured
       Notes.  See "Description of the Certificates" and "Description of the
       Secured Notes."  In the event that, at the time Certificates are issued,
       the Secured Notes to be

                                       9
<PAGE>
 
       purchased by the applicable Pass Through Trust or Pass Through Trusts are
       not available for purchase, the proceeds of the sale of such Certificates
       may be used by the Trustee to purchase certain limited investments on an
       interim basis, as described in the applicable Prospectus Supplement.  In
       such event, any portion of the proceeds of the sale of such Certificates
       not used for the purchase of Secured Notes on or prior to the date set
       forth in such Prospectus Supplement will be distributed on a Special
       Distribution Date (as defined below) to the applicable
       Certificateholders, together with interest, but without premium.  See
       "Description of the Certificates--Delayed Purchase."

                        DESCRIPTION OF THE CERTIFICATES

         In connection with each offering of Certificates, one or more separate
       Pass Through Trusts will be formed and one or more series of Certificates
       will be issued pursuant to the Basic Agreement and one or more separate
       Trust Supplements to be entered into among Mobil, the Applicable Lessee
       or Applicable Lessees and the Trustee on behalf of the related Pass
       Through Trust.  The statements made under this caption are summaries and
       do not purport to be complete. Reference is made to, and the summaries
       are qualified in their entirety by reference to, the detailed provisions
       of the Basic Agreement, the form of which has been filed as an exhibit to
       the Registration Statement of which this Prospectus is a part and which
       will be qualified under the Trust Indenture Act of 1939, as amended (the
       "Trust Indenture Act").  The summaries relate to the Basic Agreement to
       be entered into and each of the Trust Supplements, the Pass Through
       Trusts to be formed thereby and the Certificates to be issued by each
       Pass Through Trust except to the extent, if any, described in the
       applicable Prospectus Supplement. Reference is also made to, and the
       summaries are qualified in their entirety by reference to, the detailed
       provisions of the form of Parent Guaranty, which has been filed as an
       exhibit to the Registration Statement of which this Prospectus is a part.
       The Trust Supplement relating to each series of Certificates and the
       forms of the related Indenture, Lease, Participation Agreement or similar
       agreements will be filed as exhibits to a post-effective amendment to the
       Registration Statement of which this Prospectus is a part, a Current
       Report on Form 8-K, a Quarterly Report on Form 10-Q or an Annual Report
       on Form 10-K, as applicable, to be filed by Mobil with the Commission.

         The Certificates offered pursuant to this Prospectus will be limited to
       $650,000,000 aggregate public offering price (or its equivalent (based on
       the applicable exchange rate at the time of sale) in one or more foreign
       currencies or units based on or related to currencies, including European
       Currency Units).

         Certain provisions of the description of the Certificates in this
       Prospectus do not necessarily apply to one Certificate of each Pass
       Through Trust which may be issued in a denomination of less than $1,000.

         To the extent that any provision in any Prospectus Supplement is
       inconsistent with any provision in this summary, the provision of such
       Prospectus Supplement will control.

       GENERAL

         Each Certificate will represent a fractional undivided interest in the
       Pass Through Trust created by the Trust Supplement pursuant to which such
       Certificate was issued and all payments and distributions shall be made
       only from the related Trust Property (as defined below).  The property of
       each Pass Through Trust (the "Trust Property") will include the Secured
       Notes held

                                       11
<PAGE>
 
       in such Pass Through Trust, all monies at any time paid thereon and all
       monies due and to become due thereunder and funds from time to time
       deposited with the Trustee in accounts relating to such Pass Through
       Trust.  Each Certificate will represent a pro rata share of the
       outstanding principal amount of the Secured Notes held in the related
       Pass Through Trust and, unless otherwise specified in the applicable
       Prospectus Supplement, will be issued in minimum denominations of $1,000
       or any integral multiple thereof.  The Certificates do not represent an
       interest in or obligation of Mobil, any Lessee, the Trustee, any of the
       Indenture Trustees or Owner Trustees in their individual capacities, any
       Owner Participant, or any of their respective affiliates.  Each
       Certificateholder by its acceptance of a Certificate agrees to look
       solely to the income and proceeds from the Trust Property as provided in
       the Basic Agreement and the applicable Trust Supplement.

         No holder of a Certificate issued with respect to a Pass Through Trust
       will have any rights, benefits or interests in respect of any other Pass
       Through Trust or in the property held by any other Pass Through Trust.
       All payments and distributions on the Certificates will be made only from
       the related Trust Property, or pursuant to intercreditor, subordination
       or similar agreements to which the related Trustee may be a party.

         Secured Notes issued under an Indenture may be held in more than one
       Pass Through Trust and one Pass Through Trust may hold Secured Notes
       issued under more than one Indenture.

         Interest will be passed through to Certificateholders of each Pass
       Through Trust at the rate per annum payable on the Secured Notes held in
       such Pass Through Trust, as set forth for such Pass Through Trust on the
       cover page of the applicable Prospectus Supplement.

         None of the Basic Agreement, the Indentures nor the Leases will include
       financial covenants or "event risk" provisions that would afford
       Certificateholders protection in the event of a highly leveraged or other
       transaction involving Mobil or the Lessees.  The Certificateholders will
       have the benefit of a lien on the Leased Property and the other property
       in each Indenture Estate securing the Secured Notes held in the related
       Pass Through Trust, as discussed under "Description of the Secured Notes-
       -Security."

         Reference is made to the Prospectus Supplement that accompanies this
       Prospectus for a description of the specific series of Certificates being
       offered thereby, including: (1) the specific designation and title of
       such Certificates; (2) the Regular Distribution Dates (as defined below)

       Secured Notes to be purchased by the related Pass Through Trust,
       including the period or periods within which, the price or prices at
       which, and the terms and conditions upon which such Secured Notes may or
       must be redeemed, purchased or defeased in whole or in part, by the
       Applicable Lessee or the related Owner Trustee or Owner Participant, (6)
       a description of the related Leased Property and the rights and interests

<PAGE>
 
       Applicable Lessee and others therein; (7) a description of the related
       Indenture, including a description of the events of default under the
       related Indenture, the remedies exercisable upon the occurrence of such
       events of default and any limitations on the exercise of such remedies

       of the Applicable Lessee to pay rent under the related Lease; (9) the

       holders of a specified percentage of aggregate principal amount of, such
       Secured Notes; (10) the terms of the related Parent Guaranty; (11) the
       terms of any intercreditor, subordination or similar agreement relating
       to the Certificates or Secured Notes or of any liquidity or credit
       facility and (12) any other special terms pertaining to such Certificates
       or Secured Notes, including any modification of the terms set forth
       herein.

         If any Certificates are denominated in one or more foreign currencies
       or currency units, the restrictions, certain United States federal income
       tax considerations, specific terms and other information with respect to
       such Certificates and such foreign currency or currency units will be set
       forth in the applicable Prospectus Supplement.
    
         If any Certificates relate to Secured Notes that were sold at a
       substantial discount below the stated principal amount of such Secured
       Notes, certain United States federal income tax considerations, specific
       terms and other information with respect to such Certificates will be set
       forth in the applicable Prospectus Supplement.      

       BOOK-ENTRY REGISTRATION

       GENERAL

         If specified in the applicable Prospectus Supplement, the Certificates
       issued thereunder will be subject to the provisions described below and
       under the caption "--Definitive Certificates." Upon issuance, each series
       of Certificates will be represented by one fully registered global
       certificate.  Each global certificate will be deposited with, or on
       behalf of, The Depository Trust Company ("DTC") and registered in the
       name of Cede & Co. ("Cede"), or its nominee.  No person acquiring an
       interest in such Certificates ("Certificate Owner") will be entitled to
       receive a certificate representing such person's interest in such
       Certificates, except as set forth below under "--Definitive
       Certificates." Unless and until Definitive Certificates (as defined
       below) are issued under the limited circumstances described herein and in
       the applicable Prospectus Supplement, all references to actions by
       Certificateholders shall refer to actions taken by DTC upon instructions
       from DTC Participants (as defined below), and all references herein to
       distributions, notices, reports and statements to Certificateholders
       shall refer, as the case may be, to distributions, notices, reports and
       statements to DTC or Cede, as the registered holder of such Certificates,
       or to DTC Participants for distribution to Certificate Owners in
       accordance with DTC procedures.

         DTC is a limited purpose trust company organized under the laws of the
       State of New York, a member of the Federal Reserve System, a "clearing
       corporation" within the meaning of the

                                       13

       New York Uniform Commercial Code and a "clearing agency" registered
       pursuant to section 17A of the Exchange Act.  DTC holds securities for
       its participants ("DTC Participants") and facilitates the clearance and
       settlement of securities transactions between DTC Participants through
       electronic computerized book-entries in DTC Participants' accounts,
       thereby eliminating the need for physical movement of certificates.  DTC
       Participants include securities brokers and dealers, banks, trust
       companies and clearing corporations.  Indirect access to the DTC system
       also is available to others such as banks, brokers, dealers and trust
       companies that clear through or maintain a custodial relationship with a
       DTC Participant either directly or indirectly ("Indirect Participants").

         Certificate Owners that are not DTC Participants or Indirect
       Participants but desire to purchase, sell or otherwise transfer ownership
       of, or other interests in, the Certificates may do so only through DTC
       Participants and Indirect Participants.  In addition, Certificate Owners
       will receive all distributions of principal and interest from the Trustee
       through DTC Participants or Indirect Participants, as the case may be.
       Under a book-entry format, Certificate Owners may experience some delay
       in their receipt of payments, because such payments will be forwarded by
       the Trustee to Cede, as nominee for DTC.  DTC will forward such payments
       in same-day funds to DTC Participants who are credited with ownership of
       the Certificates in amounts proportionate to the principal amount of each
       such DTC Participant's respective holdings of beneficial interests in the
       Certificates.  DTC Participants will thereafter forward payments to
       Indirect Participants or Certificate Owners, as the case may be, in
       accordance with customary industry practices.  The forwarding of such
       distributions to the Certificate Owners will be the responsibility of
       such DTC Participants.  Unless and until the Definitive Certificates are
       issued under the limited circumstances described herein, the only
       "Certificateholder" will be Cede, as nominee of DTC.  Certificate Owners
       will not be recognized by the Trustee as Certificateholders, as such term
       is used in the Basic Agreement, and Certificate Owners will be permitted
       to exercise the rights of Certificateholders only indirectly through DTC
       and DTC Participants.

         Under the rules, regulations and procedures creating and affecting DTC
       and its operations (the "Rules"), DTC is required to make book-entry
       transfers of the Certificates among DTC Participants on whose behalf it
       acts with respect to the Certificates and to receive and transmit to DTC
       Participants distributions of principal, premium, if any, and interest
       with respect to the Certificates.  DTC Participants and Indirect
       Participants with which Certificate Owners have accounts with respect to
       the Certificates similarly are required to make book-entry transfers and
       receive and transmit such payments on behalf of their respective
       customers.  Accordingly, although Certificate Owners will not possess the
       Certificates, the Rules provide a mechanism by which Certificate Owners
       will receive payments and will be able to transfer their interests.

         Because DTC can only act on behalf of DTC Participants, who in turn act
       on behalf of Indirect Participants, the ability of a Certificate Owner to
       pledge the Certificates to persons or entities that do not participate in
       the DTC system, or to otherwise act with respect to such Certificates,
       may be limited due to the lack of a physical certificate for such
       Certificates.

                                       14

         DTC will take any action permitted to be taken by a Certificateholder
       under the Basic Agreement only at the direction of one or more DTC
       Participants to whose accounts with DTC the Certificates are credited.
       Additionally, in the event any action requires approval by
       Certificateholders of a certain percentage of beneficial interest in each
       Pass Through Trust, DTC will take such action only at the direction of
       and on behalf of DTC Participants whose holders include undivided
       interests that satisfy any such percentage.  DTC may take conflicting
       actions with respect to other undivided interests to the extent that such
       actions are taken on behalf of DTC Participants whose holders include
       such undivided interests.

         None of Mobil, the Lessees or the Trustee will have any liability for
       any aspect of the records relating to or payments made on account of
       beneficial ownership interests in the Certificates held by Cede, as
       nominee for DTC, or for maintaining, supervising or reviewing any records
       relating to such beneficial ownership interests.

         The applicable Prospectus Supplement will specify any additional book-
       entry registration procedures applicable to Certificates denominated in a
       currency other than United States dollars.

         The information in this section concerning DTC and DTC's book-entry
       system has been attained from sources that Mobil believes to be reliable,
       but neither Mobil nor any Lessee has independently verified such
       information or takes responsibility for its accuracy.

       DEFINITIVE CERTIFICATES

         Certificates will be issued in fully registered certificated form
       ("Definitive Certificates") to Certificate Owners or their nominees,
       rather than to DTC or its nominee, only if (i) the Applicable Lessee
       advises the Trustee in writing that DTC is no longer willing or able to
       discharge properly its responsibilities as depository with respect to
       such Certificates and the Trustee or such Lessee is unable to locate a
       qualified successor, (ii) the Applicable Lessee, at its option, elects to
       terminate the book-entry system through DTC or (iii) after the occurrence
       of certain events of default or other events specified in the related
       Prospectus Supplement, Certificate Owners of Certificates evidencing
       fractional undivided interests aggregating not less than a majority in
       interest in the related Pass Through Trust advise the Trustee, the
       Applicable Lessee and DTC through DTC Participants in writing that the
       continuation of a book-entry system through DTC (or a successor thereto)
       is no longer in the Certificate Owners' best interest.

         Upon the occurrence of any event described in the immediately preceding
       paragraph, the Trustee will be required to notify all Certificate Owners
       through DTC Participants of the availability of Definitive Certificates.
       Upon surrender by DTC of the global certificates representing the
       Certificates and receipt of instructions for re-registration, the Trustee
       will reissue the Certificates as Definitive Certificates to Certificate
       Owners.

         Distributions of principal, premium, if any, and interest with respect
       to Certificates will thereafter be made by the Trustee directly in
       accordance with the procedures set forth in the

                                       15
<PAGE>
 
       Basic Agreement and the applicable Trust Supplements, to holders in whose
       names the Definitive Certificates were registered at the close of
       business on the applicable record date.  Such distributions will be made
       by check mailed to the address of such holder as it appears on the
       register maintained by the Trustee.  The final payment on any
       Certificate, however, will be made only upon presentation and surrender
       of such Certificate at the office or agency specified in the notice of
       final distribution to Certificateholders.

         Definitive Certificates will be freely transferable and exchangeable at
       the office of the Trustee upon compliance with the requirements set forth
       in the Basic Agreement and the applicable Trust Supplements.  No service
       charge will be imposed for any registration of transfer or exchange, but
       payment of a sum sufficient to cover any tax or other governmental charge
       shall be required.

       PAYMENTS AND DISTRIBUTIONS

         Payments of principal, premium, if any, and interest with respect to
       the Secured Notes held in each Pass Through Trust will be distributed by
       the Trustee, upon receipt, to Certificateholders of such Pass Through
       Trust on the dates and in the currency specified in the applicable
       Prospectus Supplement, except in certain cases when some or all of such
       Secured Notes are in default as described in the applicable Prospectus
       Supplement.  Payments of principal of, and interest on, the Secured Notes
       held in each Pass Through Trust will be scheduled to be received by the
       Trustee on the dates specified in the applicable Prospectus Supplement
       (such scheduled payments of interest and principal on the Secured Notes
       to the Trustee are herein referred to as "Scheduled Payments," and the
       dates specified in the applicable Prospectus Supplement for distribution
       of Scheduled Payments by the Trustee are herein referred to as "Regular
       Distribution Dates").  Each Certificateholder of each Pass Through Trust
       will be entitled to receive a pro rata share of any distribution in
       respect of Scheduled Payments of principal and interest made on the
       Secured Notes held in such Pass Through Trust.  The Regular Distribution
       Dates on which, and the amounts in which, Scheduled Payments of principal
       on the Secured Notes held in each Pass Through Trust are payable will be
       set forth in the accompanying Prospectus Supplement.

         Payments of principal, premium, if any, and interest received by the
       Trustee on account of the redemption or purchase, if any, of any of the
       Secured Notes held in a Pass Through Trust, and payments received by the
       Trustee following an Event of Default (as defined below) in respect of
       any of the Secured Notes held in a Pass Through Trust (including payments
       received by the Trustee on account of the purchase by the related Owner
       Trustees or Owner Participants of such Secured Notes or payments received
       on account of the sale of such Secured Notes by the Trustee) ("Special
       Payments") will be distributed on a date or dates described in the
       accompanying Prospectus Supplement (each, a "Special Distribution Date").
       The Trustee will mail notice to the Certificateholders of record of the
       related Pass Through Trust not less than 20 days prior to the Special
       Distribution Date on which any Special Payment is scheduled to be
       distributed by the Trustee in the event the Secured Notes are to be
       redeemed or purchased prior to their maturity and, in all other
       instances, as soon as practicable after the Trustee has received the
       Special Payment.  The notice will specify the anticipated Special
       Distribution Date, the

                                       16
<PAGE>
 
       amount of such anticipated Special Payment, the reason for the Special
       Payment and the total amount to be distributed if such Special
       Distribution Date is the same date as a Regular Distribution Date.  Each
       distribution of a Special Payment, other than a final distribution, on a
       Special Distribution Date for a Pass Through Trust will be made by the
       Trustee to the Certificateholders of such Pass Through Trust on the
       record date prior to such Special Distribution Date.

         The Basic Agreement requires that the Trustee establish and maintain,
       for the benefit of the Certificateholders of each Pass Through Trust, one
       or more non-interest bearing accounts (with respect to each such Pass
       Through Trust, the "Certificate Account") for the deposit of payments
       representing Scheduled Payments on the Secured Notes held in the related
       Pass Through Trust. The Basic Agreement also requires that the Trustee
       establish and maintain, for the benefit of the Certificateholders of each
       Pass Through Trust, one or more non-interest bearing accounts (with
       respect to each such Pass Through Trust, the "Special Payments Account")
       for the deposit of payments representing Special Payments.  Pursuant to
       the terms of the Basic Agreement, the Trustee is required to deposit any
       Scheduled Payments on the Secured Notes held in the applicable Pass
       Through Trust received by it in the Certificate Account for such Pass
       Through Trust and to deposit any Special Payments so received by it in
       the Special Payments Account for such Pass Through Trust.  All amounts so
       deposited will be distributed by the Trustee on a Regular Distribution
       Date or a Special Distribution Date, as the case may be, to the
       Certificateholders of such Pass Through Trust.

         If any Regular Distribution Date or Special Distribution Date is not a
       business day, distributions scheduled to be made on such Regular
       Distribution Date or Special Distribution Date may be made on the next
       succeeding business day without interest.

       POOL FACTORS

         Unless there has been an early redemption, or a purchase of one or more
       of the Secured Notes held in a Pass Through Trust by the related Owner
       Trustee or Owner Participant after an Indenture Event of Default (as
       defined below), a default in the payment of principal in respect of one
       or more issues of the Secured Notes held in a Pass Through Trust or
       certain actions have been taken following a default thereon, as described
       in the applicable Prospectus Supplement, the Pool Factor (as defined
       below) for each Pass Through Trust will decline in proportion to the
       scheduled repayments of principal on the Secured Notes held in such Pass
       Through Trust as described in the applicable Prospectus Supplement.  In
       the event of such redemption, purchase or default, the Pool Factor and
       the Pool Balance (as defined below) of each Pass Through Trust so
       affected will be recomputed after giving effect thereto and notice
       thereof will be mailed to the Certificateholders of such Pass Through
       Trust.  Each Pass Through Trust will have a separate Pool Factor.

         Unless otherwise described in the applicable Prospectus Supplement, the
       "Pool Balance" for each Pass Through Trust indicates, as of any Regular
       Distribution Date or Special Distribution Date, the aggregate unpaid
       principal amount of the Secured Notes held in such Pass Through

                                       17
<PAGE>
 
       Trust on such date plus any amounts in respect of principal on such
       Secured Notes held by the Trustee and not yet distributed.  The Pool
       Balance for each Pass Through Trust as of any Regular Distribution Date
       or Special Distribution Date shall be computed after giving effect to the
       payment of principal, if any, on the Secured Notes held in such Pass
       Through Trust and the distribution thereof to be made on that date.

         Unless otherwise described in the applicable Prospectus Supplement, the
       "Pool Factor" for each Pass Through Trust as of any Regular Distribution
       Date or Special Distribution Date is the quotient (rounded to the seventh
       decimal place) computed by dividing (i) the then outstanding Pool Balance
       by (ii) the aggregate original principal amount of the Certificates
       issued by such Pass Through Trust.  The Pool Factor for each Pass Through
       Trust as of any Regular Distribution Date or Special Distribution Date
       shall be computed after giving effect to the payment of principal, if
       any, on the Secured Notes held in such Pass Through Trust and
       distribution thereof to be made on that date.  The Pool Factor for each
       Pass Through Trust will initially be 1.0000000; thereafter, the Pool
       Factor for each Pass Through Trust will decline as described above to
       reflect reductions in the Pool Balance of such Pass Through Trust.  The
       amount of a Certificateholder's pro rata share of the Pool Balance of a
       Pass Through Trust can be determined by multiplying the original
       denomination of the holder's Certificate of such Pass Through Trust by
       the Pool Factor for such Pass Through Trust as of the applicable Regular
       Distribution Date or Special Distribution Date.  The Pool Factor and the
       Pool Balance for each Pass Through Trust will be mailed to
       Certificateholders of such Pass Through Trust on each Regular
       Distribution Date and Special Distribution Date.

       REPORTS TO CERTIFICATEHOLDERS

         On each Regular Distribution Date and Special Distribution Date, the
       Trustee will include with each distribution of a Scheduled Payment or
       Special Payment to Certificateholders of the related Pass Through Trust a
       statement, giving effect to such distribution to be made on such Regular
       Distribution Date or Special Distribution Date, as the case may be,
       setting forth the following information (per $1,000 aggregate principal
       amount of Certificate for such Pass Through Trust, as to (i) and (ii)
       below):

         (i)  the amount of such distribution allocable to principal and the
       amount allocable to premium, if any;

         (ii)  the amount of such distribution allocable to interest; and

         (iii)  the Pool Balance and the Pool Factor for such Pass Through
       Trust.

         So long as the Certificates are registered in the name of Cede, as
       nominee for DTC, on the record date prior to each Regular Distribution
       Date and Special Distribution Date, the Trustee will request from DTC a
       Securities Position Listing setting forth the names of all DTC
       Participants reflected on DTC's books as holding interests in the
       Certificates on such record date.  On each Regular Distribution Date and
       Special Distribution Date, the Trustee will mail

                                       18
<PAGE>
 
       to each such DTC Participant the statement described above and will make
       available additional copies as requested by such DTC Participant for
       forwarding to Certificate Owners.

         In addition, after the end of each calendar year, the Trustee will
       prepare for each Certificateholder of each Pass Through Trust at any time
       during the preceding calendar year a report containing the sum of the
       amounts determined pursuant to clauses (i) and (ii) above with respect to
       the Pass Through Trust for such calendar year or, in the event such
       person was a Certificateholder during only a portion of such calendar
       year, for the applicable portion of such calendar year, and such other
       items as are readily available to the Trustee and which a
       Certificateholder shall reasonably request as necessary for the purpose
       of such Certificateholder's preparation of its federal income tax
       returns.  Such report and such other items shall be prepared on the basis
       of information supplied to the Trustee by the DTC Participants and shall
       be delivered by the Trustee to such DTC Participants to be available for
       forwarding by such DTC Participants to Certificate Owners in the manner
       described above.

         At such time, if any, as the Certificates are issued in the form of
       Definitive Certificates, the Trustee will prepare and deliver the
       information described above to each Certificateholder of record of each
       Pass Through Trust as the name and period of beneficial ownership of such
       Certificateholder appears on the records of the registrar of the
       Certificates.

       VOTING OF SECURED NOTES

         The Trustee, as holder of the Secured Notes held in a Pass Through
       Trust, will have the right to vote and give consents and waivers with
       respect to such Secured Notes under the related Indenture.  The Basic
       Agreement and related Trust Supplement will set forth (i) the
       circumstances in which a Trustee may direct any action or cast any vote,
       as the holder of the Secured Notes held in the applicable Pass Through
       Trust, in its own discretion, (ii) the circumstances in which such
       Trustee shall seek instructions from the Certificateholders of such Pass
       Through Trust and (iii) the percentage of Certificateholders required to
       direct such Trustee to take any such action.

       EVENTS OF DEFAULT AND CERTAIN RIGHTS UPON AN EVENT OF DEFAULT
    
         The Basic Agreement defines an event of default with respect to a Trust
       (an "Event of Default") as the occurrence and continuance of an event of
       default under one or more of the related Indentures (an "Indenture Event
       of Default"). The Prospectus Supplement for a series of Certificates will
       specify the Indenture Events of Default under the related Indentures.
       Certain of the Indenture Events of Default will arise with reference to
       events of default under the relevant Lease (a "Lease Event of Default").
       Since the Secured Notes issued under an Indenture may be held in more
       than one Pass Through Trust, a continuing Indenture Event of Default
       under such Indenture would result in an Event of Default under each Pass
       Through Trust holding such Secured Notes. Unless otherwise provided in a
       Prospectus Supplement, all of the Secured Notes issued under the same
       Indenture will relate only to specified Leased Property, there will be no
       cross-collateralization or cross-default provisions in the Indentures,
       and events resulting in an Indenture Event of Default under any
       particular Indenture will not necessarily result in an Indenture Event of
       Default occurring under any other     

                                       19
<PAGE>
 
       Indentures.  If an Indenture Event of Default occurs in fewer than all of
       the Indentures related to a Pass Through Trust, notwithstanding the
       treatment of Secured Notes issued under any related Indenture under which
       an Indenture Event of Default has occurred, payments of principal and
       interest on the Secured Notes issued pursuant to any related Indenture
       with respect to which an Indenture Event of Default has not occurred will
       continue to be made as originally scheduled.

         The ability of the applicable Owner Trustee or Owner Participant under
       the related Indenture to cure Indenture Events of Default, including
       Indenture Events of Default that result from the occurrence of a Lease
       Event of Default under the related Lease, will be described in the
       applicable Prospectus Supplement.

         The ability of the Certificateholders with respect to any one Pass
       Through Trust to cause the Indenture Trustee with respect to any Secured
       Notes held in such Pass Through Trust to accelerate the Secured Notes
       under the related Indenture or to direct the exercise of remedies by the
       Indenture Trustee under the related Indenture will depend, in part, upon
       the proportion between the aggregate principal amount of the Secured
       Notes outstanding under such Indenture and held in such Pass Through
       Trust and the aggregate principal amount of all Secured Notes outstanding
       under such Indenture.  If Secured Notes outstanding under an Indenture
       are held by more than one Pass Through Trust, then each Pass Through
       Trust will hold Secured Notes with different terms from the Secured Notes
       held in the other Pass Through Trusts and therefore the
       Certificateholders of a Pass Through Trust may have divergent or
       conflicting interests from those of the Certificateholders of the other
       Pass Through Trusts holding Secured Notes relating to the same Indenture.
       In addition, so long as the same institution acts as Trustee of each Pass
       Through Trust, in the absence of instructions from the Certificateholders
       of any such Pass Through Trust, the Trustee for such Pass Through Trust
       could for the same reason be faced with a potential conflict of interest
       upon an Indenture Event of Default.  In such event, the Basic Agreement
       will provide that the Trustee will resign as trustee of one or all such
       Pass Through Trusts, and a successor trustee will be appointed in
       accordance with the terms of the Basic Agreement.
    
         As an additional remedy, if an Indenture Event of Default under an
       Indenture shall have occurred and be continuing, the Basic Agreement
       provides that the Trustee of a Pass Through Trust holding Secured Notes
       issued under such Indenture may, and upon the direction of the holders of
       Certificates evidencing fractional undivided interests aggregating not
       less than a majority in interest of such Pass Through Trust shall, sell
       all or part of such Secured Notes for cash to any person. Any proceeds
       received by the Trustee upon any such sale shall be deposited in the
       Special Payments Account for the Certificateholders of such series and
       shall be distributed to the Certificateholders of the related Pass
       Through Trust on a Special Distribution Date. The market for Secured
       Notes in default may be very limited, and there can be no assurance that
       they could be sold for a reasonable price. Furthermore, so long as the
       same institution acts as Trustee of multiple Pass Through Trusts, it may
       be faced with a conflict in deciding from which Pass Through Trust to
       sell Secured Notes to available buyers. If the Trustee sells any such
       Secured Notes with respect to which an Indenture Event of Default exists
       for less than their outstanding principal amount, the Certificateholders
       of such Pass Through Trust will receive a smaller amount of principal
       distributions than anticipated and will not have any claim for the
       shortfall against Mobil, any Lessee, any Owner Trustee, any Owner
       Participant or the Trustee. Furthermore, neither the Trustee nor the
       Certificateholders of such     

                                       20
<PAGE>
 
       Pass Through Trust could take any action with respect to any remaining
       Secured Notes held in such Pass Through Trust so long as no Indenture
       Events of Default exist with respect thereto.

         Any amount, other than Scheduled Payments received on a Regular
       Distribution Date, distributed to the Trustee of any Pass Through Trust
       by the Indenture Trustee under any Indenture on account of the Secured
       Notes held in such Pass Through Trust following an Indenture Event of
       Default under such Indenture shall be deposited in the Special Payments
       Account for such Pass Through Trust and shall be distributed to the
       Certificateholders of such Pass Through Trust on a Special Distribution
       Date.  In addition, if a Prospectus Supplement provides that the
       applicable Owner Trustee or Owner Participant may, under circumstances
       specified therein, redeem or purchase the outstanding Secured Notes
       issued under the related Indenture, the price paid by such Owner Trustee
       or Owner Participant to the Trustee of any Pass Through Trust for the
       Secured Notes issued under such Indenture and held in such Pass Through
       Trust shall be deposited in the Special Payments Account for such Pass
       Through Trust and shall be distributed to the Certificateholders of such
       Pass Through Trust on a Special Distribution Date.
    
         Any funds representing payments received with respect to any Secured
       Notes in default held in a Pass Through Trust, or the proceeds from the
       sale by the Trustee of any such Secured Notes, held by the Trustee in the
       Special Payments Account for such Pass Through Trust shall, to the extent
       practicable, be invested and reinvested by the Trustee in Permitted
       Investments pending the distribution of such funds on a Special
       Distribution Date. "Permitted Investments" are obligations of the United
       States maturing in not more than 60 days or such lesser time as is
       required for the distribution of any such funds on a Special Distribution
       Date.      

         The Basic Agreement will provide that the Trustee of a Pass Through
       Trust shall, within 90 days after the occurrence of a default in respect
       of such Pass Through Trust, give to the Certificateholders of such Pass
       Through Trust notice, transmitted by mail, of all uncured or unwaived
       defaults with respect to such Pass Through Trust known to it, provided
       that, except in the case of default in the payment of principal, premium,
       if any, or interest on any of the Secured Notes held in such Pass Through
       Trust, the Trustee shall be protected in withholding such notice if it in
       good faith determines that the withholding of such notice is in the
       interests of such Certificateholders.  The term "default" as used in this
       paragraph only means the occurrence of an Event of Default with respect
       to a Pass Through Trust as described above, except that in determining
       whether any such Event of Default has occurred, any grace period or
       notice in connection therewith shall be disregarded.

         The Basic Agreement contains a provision entitling the Trustee of each
       Pass Through Trust, subject to the duty of the Trustee during a default
       to act with the required standard of care, to be offered reasonable
       security or indemnity by the Certificateholders of such Pass Through
       Trust before proceeding to exercise any right or power under the Basic
       Agreement at the request of such Certificateholders.
             
         In certain cases, the holders of Certificates of a Pass Through Trust
       evidencing fractional undivided lnterests aggregating not less than a
       majority in interest of such Pass Through Trust may on behalf of the
       holders of all Certificates of such Pass Through Trust waive any past
       default or Event of Default with respect to such Pass Through Trust and
       its consequences, except (i) a default in payment of the principal of,
       premium, if any, or interest on any of the Secured Notes held in such
       Pass Through Trust and (ii) a default in respect of any covenant or
       provision of the Basic Agreement or the related Trust Supplement that
       cannot be modified or amended without the consent of each
       Certificateholder of such Pass Through Trust affected thereby.  Each
       Indenture will provide that, with certain exceptions, the holders of a
       majority in aggregate unpaid principal amount of the Secured Notes issued
       thereunder and held in a related Pass Through Trust may on behalf of all
       such holders waive any past default or Indenture Event of Default
       thereunder. In the event of a waiver with respect to a Pass Through Trust
       as described above, the principal amount of the Secured Notes issued
       under the related Indenture held in such Pass Through Trust shall be
       counted as waived in the determination of the majority in aggregate
       unpaid principal amount of Secured Notes required to waive a default or
       an Indenture Event of Default under such Indenture.  Therefore, if the
       Certificateholders of a Pass Through Trust or Pass Through Trusts waive a
       past default or Event of Default such that the principal amount of the
       Secured Notes held either individually in such Pass Through Trust or in
       the aggregate in such Pass Through Trusts constitutes the required
       majority in aggregate unpaid principal amount under the applicable
       Indenture, such past default or Indenture Event of Default under such
       Indenture shall be waived.

       MODIFICATIONS OF THE BASIC AGREEMENT
    
         The Basic Agreement contains provisions permitting Mobil, the
       Applicable Lessee or Applicable Lessees and the Trustee of each Pass
       Through Trust to enter into a supplemental trust agreement, without the
       consent of the holders of any of the Certificates of such Pass Through
       Trust, (i) to provide for the formation of such Pass Through Trust and
       the issuance of a series of Certificates, (ii) to evidence the succession
       of another corporation to Mobil or a Lessee and the assumption by such
       corporation of Mobil's or such Lessee's obligations with respect to one
       or more series of Certificates under the Basic Agreement and the
       applicable Trust Supplement, (iii) to add to the covenants of Mobil or a
       Lessee for the benefit of holders of such Certificates, or to surrender
       any right or power in the Basic Agreement conferred upon Mobil or a
       Lessee, (iv) to cure any ambiguity or correct or supplement any defective
       or inconsistent provision of the Basic Agreement or the applicable Trust
       Supplement or to make any other provisions with respect to matters or
       questions arising under the Basic Agreement as may be necessary or
       desirable, provided such action shall not adversely affect the interests
       of the holders of such Certificates, or to correct any mistake, (v) to
       modify, eliminate or add to the provisions of the Basic Agreement or the
       applicable Trust Supplement to the extent as shall be necessary to
       continue the qualification of the Basic Agreement (including any
       supplemental agreement) under the Trust Indenture Act and to add to the
       Basic Agreement such other provisions as may be expressly permitted by
       the Trust Indenture Act, (vi) to provide for a successor Trustee or to
       add to or change any provision of the Basic Agreement or the applicable
       Trust Supplement as shall be necessary to facilitate the administration
       of the Pass Through Trusts thereunder by more than one Trustee, (vii) to
       correct or supplement the description of any property constituting
       property of such Pass Through Trust and (viii) to make any other
       amendments or modifications to the Basic Agreement or applicable Trust
       Supplement, provided such amendments or modifications shall only apply to
       Certificates issued thereafter.    

         The Basic Agreement also contains provisions permitting Mobil, the
       Applicable Lessee or Applicable Lessees and the Trustee of a related Pass
       Through Trust, with the consent of the Certificateholders of such Pass
       Through Trust evidencing fractional undivided interests aggregating not
       less than a majority in interest of such Pass Through Trust, and, with
       respect to any Leased Property, with the consent of the applicable Owner
       Trustee (such consent not to be unreasonably withheld), to execute
       supplemental trust agreements adding any provisions to or changing or
       eliminating any of the provisions of the Basic Agreement, to the extent
       relating to such Pass Through Trust and the applicable Trust Supplement,
       or modifying the rights of the Certificateholders, except that no such
       supplemental trust agreement may, without the consent

                                       22
<PAGE>
 
       of each Certificateholder so affected thereby, (a) reduce in any manner
       the amount of, or delay the timing of, any receipt by the Trustee of
       payments on the Secured Notes held in such Pass Through Trust or
       distributions in respect of any Certificate related to such Pass Through
       Trust, or change the date or place of any payment in respect of any such
       Certificate, or make distributions payable in coin or currency other than
       that provided for in such Certificates, or impair the right of any
       Certificateholder of such Pass Through Trust to institute suit for the
       enforcement of any such payment when due, (b) permit the disposition of
       any Secured Note held in such Pass Through Trust, except as provided in
       the Basic Agreement or the applicable Trust Supplement, or otherwise
       deprive any Certificateholder of the benefit of the ownership of the
       applicable Secured Notes, (c) reduce the percentage of the aggregate
       fractional undivided interests of such Pass Through Trust provided for in
       the Basic Agreement or the applicable Trust Supplement, the consent of
       the holders of which is required for any such supplemental trust
       agreement or for any waiver provided for in the Basic Agreement or such
       Trust Supplement, or (d) modify any of the provisions relating to the
       rights of the Certificateholders in respect of the waiver of events of
       default or receipt of payment except to increase the percentage of the
       aggregate fractional undivided interests of such Pass Through Trust
       required for such a waiver.

       MODIFICATION OF INDENTURE AND RELATED AGREEMENTS
             
         In the event that the Trustee, as the holder of any Secured Notes held
       in a Pass Through Trust, receives a request for its consent to any
       amendment, modification or waiver under the Lease or other document
       relating to such Secured Notes, the Trustee shall mail a notice of such
       proposed amendment, modification or waiver to each Certificateholder of
       such Pass Through Trust as of the date of such notice. The Trustee shall
       request instructions from the Certificateholders of such Pass Through
       Trust as to whether or not to consent to such amendment, modification or
       waiver.  The Trustee shall vote or consent with respect to such Secured
       Notes in such Past Through Trust in the same proportion as the
       Certificates of such Pass Through Trust were actually voted by the
       holders thereof by a certain date.  Notwithstanding the foregoing, if an
       Event of Default in respect of such Pass Through Trust shall have
       occurred and be continuing, the Trustee may in its own discretion consent
       to such amendment, modification or waiver, and may so notify the
       Indenture Trustee to which such consent relates.     

       TERMINATION OF THE PASS THROUGH TRUSTS

         The obligations of Mobil, the Applicable Lessee and the Trustee with
       respect to a Pass Through Trust will terminate upon the distribution to
       the Certificateholders of such Pass Through Trust of all amounts required
       to be distributed to them pursuant to the Basic Agreement and the
       applicable Trust Supplement and the disposition of all property held in
       such Pass Through Trust.  The Trustee will send to each Certificateholder
       of record of such Pass Through Trust notice of the termination of such
       Pass Through Trust, the amount of the proposed final payment and the
       proposed date for the distribution of such final payment for such Pass
       Through Trust.  The final distribution to any Certificateholder of such
       Pass Through Trust will be made only upon surrender of such
       Certificateholder's Certificates at the office or agency of the Trustee
       specified in such notice of termination.

       DELAYED PURCHASE

         A Prospectus Supplement may specify that, pending availability of some
       or all of the Secured Notes intended to be purchased with the proceeds of
       an issuance of Certificates, such proceeds may, as more fully described
       in such Prospectus Supplement, be (a) invested by the Trustee in United
       States government obligations or certain other limited investments
       described in such Prospectus

                                       23
<PAGE>
 
       Supplement ("Specified Investments"), in which event Mobil or the
       Applicable Lessee would be responsible for paying to the Trustee amounts
       equal to any loss on such investments and any deficiency in the earnings
       of such investments under the amount scheduled to be distributed on such
       Certificates in respect of interest and would be entitled to receive any
       earnings on such investments in excess of the amount so needed for
       distribution on the Certificates, or (b) used by the Trustee to acquire
       debt instruments issued on an interim basis by Mobil or by one or more of
       the Applicable Lessees and guaranteed by Mobil, in each case having an
       interest rate and payment provisions corresponding to the interest rate
       and payment provisions of the Secured Notes intended to be purchased with
       such proceeds and requiring repayment to the Trustee at the time the
       Trustee is to purchase such Secured Notes.  Any such debt instruments
       will be secured by a collateral account that may be invested in Specified
       Investments or by other security described in the applicable Prospectus
       Supplement.

         To the extent that the full amount of the proceeds from the sale of any
       Certificates is not used to purchase Secured Notes on or prior to the
       date set forth in the applicable Prospectus Supplement, an amount equal
       to the unused proceeds will be distributed by the Trustee to the holders
       of record of such Certificates on a pro rata basis on a Special
       Distribution Date, together with interest thereon at a rate equal to the
       rate applicable to such Certificates, but without premium.

       THE TRUSTEE

         Except as otherwise provided in the Prospectus Supplement, State Street
       Bank and Trust Company will be the Trustee for each of the Pass Through
       Trusts.  With certain exceptions, the Trustee will make no
       representations as to the validity or sufficiency of the Basic Agreement,
       the Trust Supplements, the Certificates, the Secured Notes, the
       Indentures, the Leases or other related documents.  The Trustee shall not
       be liable with respect to any series of Certificates for any action taken
       or omitted to be taken by it in good faith in accordance with the
       direction of the holders of a majority in principal amount of outstanding
       Certificates of such series.  Subject to such provisions, such Trustee
       shall be under no obligation to exercise any of its rights or powers
       under the Basic Agreement at the request of any holders of Certificates
       issued thereunder unless they shall have offered to the Trustee indemnity
       satisfactory to it.  The Basic Agreement provides that the Trustee in its
       individual or any other capacity may acquire and hold Certificates issued
       thereunder and, subject to certain conditions, may otherwise deal with
       Mobil and the Lessees and, with respect to the Leased Property, with any
       Owner Trustee and Owner Participant with the same rights it would have if
       it were not the Trustee.

         The Trustee may resign with respect to any or all of the Pass Through
       Trusts at any time, in which event Mobil and the Applicable Lessee will
       be obligated to appoint a successor trustee. If the Trustee ceases to be
       eligible to continue as Trustee with respect to a Pass Through Trust or
       becomes incapable of acting as Trustee or becomes insolvent, Mobil and
       the Applicable Lessee may remove such Trustee, or any Certificateholder
       of such Pass Through Trust for at least six months may, on behalf of
       himself and all others similarly situated, petition any court of
       competent jurisdiction for the removal of such Trustee and the
       appointment of a successor

                                       24
<PAGE>
 
       trustee.  Any resignation or removal of the Trustee with respect to a
       Pass Through Trust and appointment of a successor trustee for such Pass
       Through Trust does not become effective until acceptance of the
       appointment by the successor trustee.  Pursuant to such resignation and
       successor trustee provisions, it is possible that a different trustee
       could be appointed to act as the successor trustee with respect to each
       Pass Through Trust related to a single offering of Certificates.  All
       references in this Prospectus to the Trustee should be read to take into
       account the possibility that the Pass Through Trusts could have different
       successor trustees in the event of such a resignation or removal.

         The Basic Agreement provides that Mobil or the Applicable Lessee will
       pay the Trustee's fees and expenses and indemnify the Trustee against
       certain liabilities.


                        DESCRIPTION OF THE SECURED NOTES

         The statements made under this caption are summaries and do not purport
       to be complete. Such statements are qualified in their entirety by, and
       reference is made to, the entire Prospectus and detailed information
       appearing in the applicable Prospectus Supplement.

         To the extent that any provision in any Prospectus Supplement is
       inconsistent with any provision in this summary, the provision of such
       Prospectus Supplement will control.

       GENERAL

         All Secured Notes related to a Leased Property and held in a Pass
       Through Trust will be issued under a separate Indenture between the
       related Owner Trustee of an Owner Trust for the benefit of the related
       Owner Participant, and the related Indenture Trustee.  Such Secured Notes
       will be nonrecourse obligations of the applicable Owner Trust.  Each such
       Secured Note will be authenticated under an Indenture by the Indenture
       Trustee.

         With respect to each Leased Property, the related Owner Trustee has
       acquired or will acquire such Leased Property and, unless otherwise
       provided in the Prospectus Supplement, has granted or will grant a lien
       on and a security interest in such Leased Property to the related
       Indenture Trustee as security for the payments of the related Secured
       Notes, and has leased or will lease such Leased Property to the
       Applicable Lessee pursuant to the related Lease which has been or will be
       assigned to the related Indenture Trustee.  Pursuant to each such Lease,
       the Applicable Lessee will be obligated to make or cause to be made
       rental and other payments to the related Indenture Trustee on behalf of
       the related Owner Trustee in amounts that will be sufficient to make
       payments of the principal and interest and, except in the limited
       circumstances set forth in the applicable Prospectus Supplement, premium,
       if any, due in respect of such Secured Notes when and as due and payable.

                                       25
<PAGE>
 
       PRINCIPAL AND INTEREST PAYMENTS

         Interest received by the Trustee on the Secured Notes held in each Pass
       Through Trust will be passed through to the Certificateholders of such
       Pass Through Trust on the dates and at the rate per annum set forth in
       the applicable Prospectus Supplement until the final distribution date
       for such Pass Through Trust.  Principal received by the Trustee on the
       Secured Notes held in each Pass Through Trust will be passed through to
       the Certificateholders of such Pass Through Trust in scheduled amounts on
       the dates set forth in the applicable Prospectus Supplement until the
       final distribution date for such Pass Through Trust.

         If any date scheduled for any payment of principal, premium, if any, or
       interest with respect to the Secured Notes is not a business day, such
       payment will be made on the next succeeding business day without any
       additional interest.

       REDEMPTION

         The applicable Prospectus Supplement will describe the circumstances,
       whether voluntary or involuntary, under which the Secured Notes may be
       redeemed or purchased prior to the stated maturity date thereof, in whole
       or in part, the premium, if any, applicable upon certain redemptions or
       purchases and other terms applying to the redemptions or purchases of
       such Secured Notes.

       SECURITY

         The Secured Notes to be held in the Pass Through Trusts will be secured
       by (i) an assignment by the related Owner Trustee to the related
       Indenture Trustee of such Owner Trustee's rights (except for certain
       rights, including those described below) under the Lease or Leases with
       respect to the related Leased Property including the right to receive
       payments of rent thereunder, (ii) an assignment of certain of such Owner
       Trustee's rights under the Parent Guaranty relating to such Leased
       Property, and (iii)  to the extent provided in the applicable Prospectus
       Supplement, a mortgage or other security interest in such Leased Property
       or in construction contracts or other agreements,  collateral accounts or
       other security, in each case subject to the rights of the Lessee under
       the Lease related thereto and other rights, if any, described in the
       applicable Prospectus Supplement.

         Under the terms of each Lease, the Applicable Lessee's obligations in
       respect of the related Leased Property will be those of a lessee under a
       "net lease." Accordingly, such Lessee will be obligated, among other
       things, to pay all costs and expenses of operating and maintaining the
       Leased Property.  With respect to the Leased Property, the assignment by
       the related Owner Trustee to the related Indenture Trustee of its rights
       under the related Lease will exclude, among other things, rights of such
       Owner Trustee and the related Owner Participant relating to
       indemnification by such Lessee for certain matters, insurance proceeds
       payable to such Owner Trustee in its individual capacity and to such
       Owner Participant under liability insurance maintained by such Lessee
       pursuant to such Lease or by such Owner Trustee or such Owner

                                       26
<PAGE>
 
       Participant, insurance proceeds payable to such Owner Trustee in its
       individual capacity or to such Owner Participant under certain casualty
       insurance maintained by such Owner Trustee or such Owner Participant
       pursuant to such Lease and any rights of such Owner Participant or such
       Owner Trustee to enforce payment of the foregoing amounts and their
       respective rights to the proceeds of the foregoing.  Such rights excluded
       from the assignment shall be referred to as "Excepted Payments."

         The applicable Prospectus Supplement will specify the required
       insurance coverage, if any, with respect to the Leased Property.

         Unless otherwise specified in the applicable Prospectus Supplement, the
       Secured Notes will not be cross-collateralized and consequently the
       Secured Notes issued in respect of any Leased Property will not be
       secured by any other Leased Property or the Lease related thereto.
       Unless and until an Indenture Event of Default with respect to a Leased
       Property has occurred and is continuing, the related Indenture Trustee
       may exercise only limited rights of the related Owner Trustee under the
       related Lease.

         Funds, if any, held from time to time by the Indenture Trustee with
       respect to any Leased Property, prior to the distribution thereof, will
       be invested and reinvested by such Indenture Trustee.  Such investment
       and reinvestment will be at the direction of the Applicable Lessee, as
       agent for the related Owner Trustee (except in the case of a related
       Lease Event of Default under the applicable Lease) in certain investments
       described in the related Indenture.  The net amount of any loss resulting
       from any such investments will be paid by such Lessee, as agent for such
       Owner Trustee.

       ADDITIONAL NOTES

         Under certain circumstances and conditions as described in the
       applicable Prospectus Supplement, for the purpose of providing funds to
       finance the cost of certain modifications, alterations, additions,
       improvements or replacement parts to any particular item of Leased
       Property, a Lessee may cause the financing of such additional costs
       through the issuance and sale by the Owner Trustee of additional Secured
       Notes (the "Additional Notes").

         The terms, conditions and designations of such Additional Notes will be
       set forth in a supplement to the related Indenture.  All rent and other
       amounts payable by the Applicable Lessee under the related Lease will be
       adjusted to the extent necessary to provide for rent and other amounts
       sufficient to provide for the payment, when due, of all scheduled
       payments of principal of, premium (except for those instances where such
       Lessee shall not be responsible for such premium), if any, and interest
       on the Secured Notes, including the Additional Notes so issued.

                                       27
<PAGE>
 
       PAYMENTS AND LIMITATION OF LIABILITY

         Each Leased Property will be leased by the applicable Owner Trustee to
       the Applicable Lessee pursuant to a Lease for a term commencing not later
       than the delivery date thereof to such Owner Trustee and expiring on a
       date not earlier than the latest maturity date of the related Secured
       Notes, unless previously terminated as permitted by the terms of such
       Lease.  The basic rent or hire and other payments under each such Lease
       will be payable by the Applicable Lessee in accordance with the terms
       specified in such Lease and will be described in the applicable
       Prospectus Supplement, and (other than Excepted Payments) will be
       assigned by the applicable Owner Trustee under the applicable Indenture
       to an Indenture Trustee to provide the funds necessary to pay principal
       and interest  and, except in the limited circumstances set forth in the
       applicable Prospectus Supplement, premium, if any, due in respect of the
       Secured Notes issued under such Indenture.  In certain cases, the basic
       rent payments under a Lease may be adjusted, but each Lease will provide
       that under no circumstances will the rental payments which the Applicable
       Lessee is obligated to make or cause to be made be less than the
       scheduled payments of principal and interest on the related Secured
       Notes.  The balance of any basic rent payment under each Lease, after
       payment of amounts due on the Secured Notes issued under the Indenture
       corresponding to such Lease, will be paid over to the applicable Owner
       Trustee.  The Applicable Lessee's obligation to pay rent and to cause
       other payments to be made under each Lease will be general obligations of
       such Lessee.

         Except in certain circumstances involving a Lessee's purchase of
       Leased Property and the assumption of the Secured Notes related thereto,
       the Secured Notes will not be obligations of, or guaranteed by, any
       Lessee or Mobil.  None of the Owner Trustees, the Owner Participants or
       the Indenture Trustees shall be personally liable to any holder of such
       Secured Notes for amounts payable under such Secured Notes, or, except as
       provided in the Indentures relating thereto in the case of the Owner
       Trustees and the Indenture Trustees, for any liability under such
       Indentures.  Except in the circumstances referred to above, all amounts
       payable under any Secured Notes (other than payments made in connection
       with an optional redemption or purchase by the related Owner Trustee or
       the related Owner Participant) will be made only from the assets subject
       to the lien of the related Indenture with respect to such Leased Property
       or the income and proceeds received by the related Indenture Trustee
       therefrom (including rent payable by the Applicable Lessee under the
       related Lease).

         Except as otherwise provided in the related Indentures, no Owner
       Trustee shall be personally liable for any amount payable or for any
       statements, representations, warranties, agreements or obligations under
       such Indentures or under the Secured Notes except for its own willful
       misconduct or gross negligence.  None of the Owner Participants shall
       have any duty or responsibility under the Indentures or under such
       Secured Notes to the related Indenture Trustee or to any holder of any
       such Secured Note.

       MERGER, CONSOLIDATION AND TRANSFER OF ASSETS

                                       28

         Each Lessee and Mobil is prohibited from consolidating with or merging
       into any other corporation or transferring substantially all of its
       assets to another corporation unless such Lessee or Mobil, as the case
       may be, is the continuing corporation or, among other things, (a) the
       successor corporation shall be a corporation organized and existing under
       the laws of the United States or any State or the District of Columbia
       or, in the case of Mobil, any other jurisdiction, and (b) the successor
       corporation shall expressly assume the due and punctual performance and
       observance of all the covenants and conditions of the operative documents
       to which such Lessee or Mobil, as the case may be, is a party and which
       are to be performed thereby.

       DEFEASANCE OF THE INDENTURES AND THE SECURED NOTES IN CERTAIN
       CIRCUMSTANCES

         Unless otherwise specified in the applicable Prospectus Supplement, the
       applicable Indenture will provide that the obligations of the related
       Indenture Trustee and the related Owner Trustee in respect of any series
       of Secured Notes issued in accordance with the terms of such Indenture
       shall be deemed to have been discharged and paid in full (except for
       certain obligations, including the obligations to register the transfer
       or exchange of Secured Notes, to replace stolen, lost, destroyed or
       mutilated Secured Notes and to maintain paying agencies and hold money
       for payment in trust) upon the irrevocable deposit with the related
       Indenture Trustee of money or certain obligations of the United States or
       any agency or instrumentality thereof the payment of which is backed by
       the full faith and credit of the United States which, through the payment
       of principal and interest in respect thereof in accordance with their
       terms, will provide money in an aggregate amount sufficient to pay when
       due (including as a consequence of redemption in respect of which notice
       is given on or prior to the date of such deposit) principal of, premium,
       if any, and interest on such Secured Notes.  Such discharge may occur
       only if, among other things, there has been published by the Internal
       Revenue Service a ruling to the effect that holders of such Secured Notes
       will not recognize income, gain or loss for federal income tax purposes
       as a result of such deposit, defeasance and discharge and will be subject
       to federal income tax on the same amount and in the same manner and at
       the same time as would have been the case if such deposit, defeasance and
       discharge had not occurred.

         Upon such defeasance, or upon payment in full of the principal of,
       premium, if any, and interest on all Secured Notes issued under any
       Indenture on the maturity date therefor or deposit with the applicable
       Indenture Trustee of money sufficient therefor no earlier than one year
       prior to the date of such maturity, the holders of such Secured Notes
       will have no beneficial interest in or other rights with respect to the
       related Leased Property or other assets subject to the lien of such
       Indenture (other than amounts or obligations deposited to effect such
       discharge) and such lien shall terminate.

       ASSUMPTION OF OBLIGATIONS BY LESSEE

         A Prospectus Supplement may specify that, with respect to any Leased
       Property and subject to the satisfaction of the conditions described in
       such Prospectus Supplement, the Applicable Lessee may, upon the exercise
       of any purchase and certain other termination options it may have under
       the related Lease, assume on a full recourse basis all of the obligations
       of the related

                                       29
<PAGE>
 
       Owner Trustee under the Indenture with respect to such Leased Property,
       including the obligations to make payments in respect of the related
       Secured Notes.  In such event, such Lessee shall execute a supplemental
       indenture to the related Indenture (such supplemental indenture, together
       with the related Indenture, a "Company Indenture").  The Parent Guaranty
       will continue to apply to such Lessee's obligations.  Unless otherwise
       specified in the applicable Prospectus Supplement, the Leased Property
       will continue to be subject to the lien of the Company Indenture, and the
       Company Indenture will incorporate certain relevant provisions of the
       Lease so terminated, including (among others) provisions relating to
       maintenance, possession and use of the related Leased Property, liens,
       insurance, possession and events of default.

       THE PARENT GUARANTIES

         As described in the applicable Prospectus Supplement, Mobil will
       unconditionally guarantee the full and prompt payment of all amounts
       payable by the Applicable Lessee under the related Lease when and as the
       same shall become due and payable.  Each Parent Guaranty will be
       enforceable without any need first to enforce any Lease against the
       Applicable Lessee.  Each Parent Guaranty will be an unsecured obligation
       of Mobil.


                        FEDERAL INCOME TAX CONSEQUENCES

         The following is a general discussion of the anticipated material
       federal income tax consequences of the purchase, ownership and
       disposition of the Certificates by a Certificate Owner purchasing
       Certificates in the initial offering thereof and should be read in
       conjunction with any additional discussion of federal income tax
       consequences included in the applicable Prospectus Supplement.  This
       summary is based on laws, regulations, rulings and decisions now in
       effect, all of which are subject to change by legislative, administrative
       or judicial action.  The discussion below does not purport to address
       federal income tax consequences applicable to particular categories of
       investors, some of which (for example, insurance companies or foreign
       investors) may be subject to special rules.  The Pass Through Trusts are
       not indemnified for any federal income taxes that may be imposed upon
       them, and the imposition of any such taxes could result in a reduction in
       the amounts available for distribution to the Certificate Owners of a
       Pass Through Trust. In connection with each offering of Certificates,
       Mobil and the Applicable Lessee will receive an opinion from Debevoise &
       Plimpton, or other counsel specified in the applicable Prospectus
       Supplement, that, based upon the applicable law then in effect, the
       following discussion, as amended or supplemented by the applicable
       Prospectus Supplement, properly describes in general the anticipated
       principal United States federal income tax consequences of acquiring,
       holding and disposing of the Certificates.

         INVESTORS SHOULD CONSULT THEIR OWN TAX ADVISORS AS TO THE FEDERAL,
       STATE, LOCAL, FOREIGN AND ANY OTHER TAX CONSEQUENCES TO THEM OF THE
       PURCHASE, OWNERSHIP AND DISPOSITION OF THE CERTIFICATES, INCLUDING THE
       ADVISABILITY OF MAKING ANY ELECTION

                                       30
<PAGE>
 
       DISCUSSED BELOW, IN LIGHT OF THEIR OWN PARTICULAR CIRCUMSTANCES.

       GENERAL

         Based upon an interpretation of analogous authorities under currently
       applicable law, each Pass Through Trust will be classified as a grantor
       trust (and not as an association taxable as a corporation) and each
       Certificate Owner will be treated as the owner of a pro rata undivided
       interest in the Secured Notes or any other property held in the
       applicable Pass Through Trust. Each Certificate Owner will be required to
       report on its federal income tax return its pro rata share of the entire
       income from the Secured Notes and any other property in the applicable
       Pass Through Trust, in accordance with such Certificate Owner's method of
       accounting.  Thus, a Certificate Owner using the cash method of
       accounting will take into account its pro rata share of income as and
       when received by the Trustee in respect of the applicable Pass Through
       Trust, and a Certificate Owner using an accrual method of accounting will
       take into account its pro rata share of income as it accrues or is
       received by the Trustee in respect of the applicable Pass Through Trust,
       whichever is earlier.

         If a Pass Through Trust will hold more than one Secured Note, a
       purchaser of a Certificate will be treated as purchasing an interest in
       each Secured Note and any other property in the related Pass Through
       Trust at a price determined by allocating the purchase price paid for the
       Certificate among such Secured Notes and other property in proportion to
       their fair market values at the time of purchase of the Certificate.

       SALES OF CERTIFICATES

         A Certificate Owner that sells a Certificate will recognize gain or
       loss (in the aggregate) equal to the difference between the amount
       realized on the sale (except to the extent attributable to accrued
       interest, which will be taxable as interest income) and the Certificate
       Owner's adjusted tax basis in the Certificate.  Subject to the market
       discount provisions of the Internal Revenue Code of 1986, as amended (the
       "Code") (described below), any such gain or loss will be capital gain or
       loss if the Certificate was held as a capital asset and, if the
       Certificate was held for more than one year, will be long-term capital
       gain or loss.  Any long-term capital gains realized will be taxable to
       corporate taxpayers at the rates applicable to ordinary income and to
       individual taxpayers at a maximum marginal rate of 28%.  Any capital
       losses realized will be deductible by a corporate taxpayer only to the
       extent of capital gains and by an individual taxpayer only to the extent
       of capital gains plus $3,000 of other income.

       MARKET DISCOUNT

         A purchaser of a Certificate (other than an original purchaser of a
       Certificate at the offering price set forth in the applicable Prospectus
       Supplement) will be considered to have acquired an interest in a Secured
       Note held in the applicable Pass Through Trust at a "market discount" to
       the extent the remaining principal amount of such Secured Note allocable
       to such Certificate exceeds the purchaser's tax basis allocable to such
       Secured Note, unless the excess does not

                                       31
<PAGE>
 
       exceed a prescribed de minimis amount.  In the event such excess exceeds
       the de minimis amount, the Certificate Owner will be subject to the
       market discount rules with regard to its interest in the Secured Note.

         In the case of a sale or other disposition of indebtedness subject to
       the market discount rules, gain, if any, from such sale or disposition
       must be treated as ordinary income to the extent such gain represents
       market discount that has accrued during the period in which the
       indebtedness was held.  If such indebtedness is disposed of in a
       nontaxable transaction, the accrued market discount (subject to certain
       exceptions) will be includible in ordinary income as if the Certificate
       Owner had sold the Certificate at its then market value.

         In the case of a partial principal payment on indebtedness subject to
       the market discount rules, such payment must be included in gross income
       as ordinary income to the extent such payment does not exceed the market
       discount that has accrued during the period such indebtedness was held.
       The amount of any accrued market discount later required to be included
       in income upon a disposition or subsequent partial principal payment will
       be reduced by the amount of accrued market discount previously included
       in income.

         Generally, market discount accrues under a straight line method, or, at
       the election of the taxpayer, under a constant interest method.  However,
       in the case of amortizing obligations, until Treasury regulations are
       issued, the explanatory Conference Committee Report to the Tax Reform Act
       of 1986 (the "Conference Report") indicates that holders of amortizing
       obligations with market discount (that do not also have original issue
       discount) may elect to accrue market discount either on the basis of a
       constant interest rate or as follows: the amount of market discount that
       is deemed to accrue is the amount of market discount that bears the same
       ratio to the total amount of remaining market discount that the amount of
       stated interest paid in the accrual period bears to the total amount of
       stated interest remaining to be paid on the amortizing obligation as of
       the beginning of such period.

         If in any taxable year interest paid or accrued on a loan incurred or
       continued to purchase or carry indebtedness subject to the market
       discount rules exceeds the interest currently includible in income with
       respect to such indebtedness, deduction of the excess interest must be
       deferred to the extent of the market discount allocable to the taxable
       year.  The deferred portion of any interest expense will generally be
       deductible when such market discount is included in income upon the sale
       or other disposition (including repayment) of the indebtedness.

         A taxpayer may elect to include market discount in its gross income
       currently.  If such election is made, the rules described above regarding
       the treatment of certain gain as ordinary income and the deferral of
       interest expense will not apply to the taxpayer.

                                       32
<PAGE>
 
       PREMIUM

         A Certificate Owner generally will be considered to have acquired an
       interest in a Secured Note held in the applicable Pass Through Trust at a
       premium to the extent the Certificate Owner's tax basis allocable to such
       Secured Note exceeds the remaining principal amount of the Secured Note
       allocable to such Certificate Owner's Certificate.  In that event, a
       Certificate Owner who holds such Certificate as a capital asset may elect
       to amortize that premium as an offset to interest income with
       corresponding reductions in the Certificate Owner's tax basis in its
       interest in the Secured Note.  This election is made by claiming the bond
       premium on the Certificate Owner's tax return.  Generally, if the
       foregoing election is made such amortization is taken on a constant yield
       basis.  However, in the case of amortizing obligations, the Conference
       Report indicates a Congressional intent that amortization should be in
       accordance with the same rules that apply to the accrual of market
       discount on amortizing obligations.  See "Market Discount."

         Under current Treasury regulations, in the case of Secured Notes that
       may be called at a premium prior to maturity, amortizable bond premium
       may be determined by reference to an early call date.  Under proposed
       Treasury regulations issued in June 1996, a holder of an obligation that
       may be called at a premium prior to maturity generally would not be
       entitled to determine the amount of amortizable bond premium by reference
       to an early call date, but may be allowed, if an early call occurred, to
       deduct all or part of any unamortized bond premium in the year of such
       call.  The proposed regulations provide that they will apply with respect
       to debt instruments issued on or after 60 days following the date final
       regulations are published in the Federal Register.  Any Prospectus
       Supplement to which such final regulations may apply will so indicate.

         Due to the complexities of the amortizable premium rules, particularly
       if there is more than one possible call date and the amount of any
       premium is uncertain, Certificate Owners are urged to consult their own
       tax advisors as to the amount of any such amortizable premium and the
       advisability of making an amortization election.

       ORIGINAL ISSUE DISCOUNT

         Unless otherwise specified in the applicable Prospectus Supplement,
       subject to the aggregation rules discussed below, the Secured Notes will
       not be issued with original issue discount. Under the aggregation rules
       set forth in the current Treasury Regulations, if one investor purchases
       Certificates issued by more than one Pass Through Trust, certain of that
       investor's interests in the Secured Notes in those Trusts must in certain
       circumstances be treated together as a single debt instrument, which, for
       purposes of calculating and amortizing any original issue discount, has a
       single issue price, maturity date, stated redemption price at maturity,
       and yield to maturity. If such aggregation  rules were applicable to an
       investor, such Secured Notes could be treated with respect to such
       investor as having been issued with original issue discount. Generally, a
       holder of a debt instrument issued with original issue discount that is
       not de minimis must include such original issue discount in income for
       federal income tax

                                       33
<PAGE>
 
       purposes as it accrues, in advance of the receipt of the cash
       attributable to such income, under a method that takes into account the
       compounding of interest. Certificate Owners are urged to consult their
       own tax advisors regarding the application of the aggregation rules.

       BACKUP WITHHOLDING

         Payments made on the Certificates, and proceeds from the sale of the
       Certificates to or through certain brokers, may be subject to a "backup"
       withholding tax of 31% unless the Certificate Owner complies with certain
       reporting procedures or is exempt from such requirements.  Any such
       withheld amounts are allowed as a credit against the Certificate Owner's
       federal income tax and may entitle such Certificate Owner to a refund,
       provided the required information is furnished to the Internal Revenue
       Service ("the IRS").  Furthermore, certain penalties may be imposed by
       the IRS on a Certificate Owner who is required to supply information but
       who does not do so in the proper manner.


                          CERTAIN MASSACHUSETTS TAXES

            The Trustee is a Massachusetts trust company with its corporate
       trust office at Two International Place, Boston, Massachusetts 02110.
       Bingham, Dana & Gould LLP, counsel to the Trustee, has advised Mobil
       that, in its opinion, under currently applicable law, assuming that each
       Pass Through Trust will not be taxable as a corporation, but, rather,
       will be classified as a grantor trust for federal income tax purposes,
       (i) the Pass Through Trusts will not be subject to any tax (including,
       without limitation, net or gross income, tangible or intangible property,
       net worth, capital, franchise or doing business tax), fee or other
       governmental charge under the laws of the Commonwealth of Massachusetts
       or any political subdivision thereof, and (ii) Certificate Owners who are
       not residents of or otherwise subject to tax in Massachusetts will not be
       subject to any tax (including, without limitation, net or gross income,
       tangible or intangible property, net worth, capital franchise or doing
       business tax), fee or other governmental charge under the laws of the
       Commonwealth of Massachusetts or any political subdivision thereof as a
       result of purchasing, holding (including receiving payments with respect
       to) or selling a Certificate.  Neither the Pass Through Trusts nor the
       Certificate Owners will be indemnified for any state or local taxes
       imposed on them, and the imposition of any such taxes on any Pass Through
       Trust could result in a reduction in the amounts available for
       distribution to the Certificate Owners of such Pass Through Trust.  In
       general, should a Certificate Owner or a Pass Through Trust be subject to
       any state or local tax which would not be imposed if the Trustee were
       located in a different jurisdiction in the United States, the Trustee
       will resign and a new trustee in such other jurisdiction will be
       appointed.

                             ERISA CONSIDERATIONS

            Unless otherwise indicated in the applicable Prospectus Supplement,
       the Certificates may, subject to certain legal restrictions, be purchased
       and held by an employee benefit plan (a "Plan") subject to Title I of the
       Employee Retirement Income Security Act of 1974, as amended ("ERISA"), or
       an individual retirement account or an employee benefit plan subject to
       section 4975 of the Code.  A fiduciary of a Plan must determine that the
       purchase and holding of a Certificate is consistent with its fiduciary
       duties under ERISA and does not result in a non-exempt prohibited
       transaction as defined in section 406 of ERISA or section 4975 of the
       Code. Employee benefit plans which are governmental plans (as defined in
       section 3(32) of ERISA) and certain church plans (as defined in section
       3(33) of ERISA) are not subject to Title I of ERISA or section 4975 of
       the Code.  The Certificates may, subject to certain legal restrictions,
       be purchased and held by such plans.


                              PLAN OF DISTRIBUTION

         Certificates may be sold to one or more underwriters for public
       offering and sale by them or to investors or other persons directly or
       through one or more dealers or agents.  Any such underwriter, dealer or
       agent involved in the offer and sale of the Certificates will be named in
       the applicable Prospectus Supplement.

         The Certificates may be sold at a fixed price or prices, which may be
       changed, or from time to time at market prices prevailing at the time of
       sale, at prices related to such prevailing market prices or at negotiated
       prices.  Dealer trading may take place in certain of the Certificates,
       including Certificates not listed on any securities exchange.  Neither
       Mobil nor the Lessees intend to apply for listing of the Certificates on
       a national securities exchange.  Mobil and the Lessees also may, from
       time to time, authorize underwriters acting as their agents to offer and
       sell the Certificates upon the terms and conditions as shall be set forth
       in any Prospectus Supplement.  In connection with the sale of
       Certificates, underwriters may be deemed to have received compensation
       from Mobil and the Applicable Lessee in the form of underwriting
       discounts or commissions and may also receive commissions from purchasers
       of Certificates for whom they may act as agent.  Underwriters may sell
       Certificates to or through dealers, and such dealers may receive
       compensation in the form of discounts, concessions or commissions from
       the underwriters and/or commissions (which may be changed from time to
       time) from the purchasers for whom they may act as agent.

         If a dealer is used directly by Mobil or a Lessee in the sale of
       Certificates in respect of which this Prospectus is delivered, such
       Certificates will be sold to the dealer, as principal.  The dealer may
       then resell such Certificates to the public at varying prices to be
       determined by such dealer at the time of resale.  Any such dealer and the
       terms of any such sale will be set forth in the Prospectus Supplement
       relating thereto.

                                       35
<PAGE>
 
         Certificates may be offered and sold through agents designated by Mobil
       and the Applicable Lessee from time to time.  Any such agent involved in
       the offer or sale of the Certificates in respect of which this Prospectus
       is delivered will be named in, and any commissions payable by Mobil and
       such Lessee to such agent will be set forth in, the applicable Prospectus
       Supplement. Unless otherwise indicated in the applicable Prospectus
       Supplement, any such agent will be acting on a best efforts basis for the
       period of its appointment.

         Offers to purchase Certificates may be solicited directly by Mobil and
       the Applicable Lessees and sales thereof may be made by Mobil and the
       Applicable Lessees directly to institutional investors or others who may
       be deemed to be underwriters within the meaning of the Securities Act
       with respect to any resale thereof.  The terms of any such sales will be
       described in the Prospectus Supplement relating thereto.  Except as set
       forth in the applicable Prospectus Supplement, no director, officer or
       employee of Mobil or the Lessees will solicit or receive a commission in
       connection with direct sales by Mobil or the Lessees of the Certificates,
       although such persons may respond to inquiries by potential purchasers
       and perform ministerial and clerical work in connection with any such
       direct sales.

         Any underwriting compensation paid by Mobil and the Applicable Lessee
       to underwriters, dealers or agents in connection with the offering of
       Certificates, and any discounts, concessions or commissions allowed by
       underwriters to participating dealers, will be set forth in an applicable
       Prospectus Supplement.  Underwriters, dealers and agents participating in
       the distribution of the Certificates may be deemed to be underwriters,
       and any discounts and commissions received by them and any profit
       realized by them on resale of the Certificates may be deemed to be
       underwriting discounts and commissions under the Securities Act.
       Underwriters, dealers and agents may be entitled, under agreements with
       Mobil and the Applicable Lessee, to indemnification against and
       contribution toward certain civil liabilities, including liabilities
       under the Securities Act, and to reimbursement by Mobil and such Lessee
       for certain expenses.

         Underwriters, dealers and agents and their affiliates may engage in
       transactions with, or perform services for, Mobil and its subsidiaries
       from time to time.

         If so indicated in an applicable Prospectus Supplement and subject to
       existing market conditions, Mobil and the Applicable Lessee will
       authorize dealers acting as Mobil's and such Lessee's agents to solicit
       offers by certain institutions to purchase Certificates at the public
       offering price set forth in such Prospectus Supplement pursuant to
       Delayed Delivery Contracts ("Contracts") providing for payment and
       delivery on the date or dates stated in such Prospectus Supplement.  Each
       Contract will be for an amount not less than, and the aggregate principal
       amount of Certificates sold pursuant to Contracts shall not be less nor
       more than, the respective amounts stated in such Prospectus Supplement.
       Institutions with whom Contracts, when authorized, may be made include
       commercial and savings banks, insurance companies, pension funds,
       investment companies, educational and charitable institutions and other
       institutions, but will in all cases be subject to the approval of Mobil
       and the Applicable Lessee.  Contracts will not be subject to any
       conditions except the purchase by an institution of the Certificates
       covered

                                       36

       by its Contracts shall not at the time of delivery be prohibited under
       the laws of any jurisdiction in the United States to which such
       institution is subject.  A commission indicated in the applicable
       Prospectus Supplement will be granted to underwriters and agents
       soliciting purchases of Certificates pursuant to Contracts accepted by
       Mobil and the Applicable Lessee.  Agents and underwriters will have no
       responsibility in respect of the delivery or performance of Contracts.

         If an underwriter or underwriters are utilized in the sale of any
       Certificates, the applicable Prospectus Supplement will contain a
       statement as to the intention, if any, of such underwriters at the date
       of such Prospectus Supplement to make a market in the Certificates.  No
       assurances can be given that there will be a market for the Certificates.

         The place and time of delivery for the Certificates in respect of which
       this Prospectus is delivered will be set forth in the applicable
       Prospectus Supplement.


                                 LEGAL OPINIONS

         Unless otherwise indicated in the applicable Prospectus Supplement, the

       ITEM 15.   INDEMNIFICATION OF DIRECTORS AND OFFICERS.

         Reference is made to the provisions of Article VI of Mobil's By-Laws,
       as amended to June 14, 1995, incorporated by reference to Exhibit 3(ii)
       to Mobil's Form 8-K, dated as of July 6, 1995.

         Section 145 of the General Corporation Law of Delaware (the "Delaware
       Law"), to which reference is hereby made, contains provisions for the
       indemnification of directors and officers on terms substantially
       identical to those contained in Mobil's By-Laws.  Article V of each
       Lessee's By-Laws provides for indemnification of the directors and
       certain officers of such Lessee to the full extent permitted by Section
       145 of the Delaware Law.

         Mobil has obtained a Directors and Officers liability insurance policy,
       effective November 1, 1995, issued by National Union Fire Insurance
       Company, and excess insurance policies issued by various commercial
       underwriters and mutual insurers effective the same date, pursuant to
       which the directors and certain officers of Mobil and the directors and
       officers of the Lessees are insured against certain liabilities they may
       incur in their respective capacities.

       ITEM 17.  UNDERTAKINGS.

         (A)  The undersigned registrants hereby undertake:

         (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
       posteffective 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 a 20% change in the maximum
       aggregate offering price set forth in the "Calculation of Registration
       Fee" table in the effective registration statement;

                                      II-3
<PAGE>
 
         (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;

         provided, however, that paragraphs (A)(1)(i) and (A)(1)(ii) do not
       apply if the registration statement is on Form S-3, Form S-8 and the
       information required to be included in a post-effective amendment by
       those paragraphs is contained in periodic reports filed by Mobil pursuant
       to Section 13 or Section 15(d) of the Securities Exchange Act of 1934, as
       amended (the "Exchange Act"), that are incorporated by reference in the
       registration statement.

         (2)  That, for the purpose of determining any liability under the
       Securities Act, 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.

         (B)  Each of the undersigned registrants hereby undertakes that, for
       purposes of determining any liability under the Securities Act, each
       filing of Mobil's annual report pursuant to section 13(a) or section
       15(d) of the Exchange Act 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.

         (C) Each of the undersigned registrants hereby undertakes, if
       securities are to be offered pursuant to competitive bidding, (1) to use
       its best efforts to distribute prior to the opening of bids, to
       prospective bidders, underwriters and dealers, a reasonable number of
       copies of a prospectus which at that time meets the requirements of
       section 10(a) of the Securities Act, and relating to the securities
       offered at competitive bidding, as contained in this registration
       statement, together with any supplements thereto, and (2) to file an
       amendment to this registration statement reflecting the results of
       bidding, the terms of the reoffering and related matters to the extent
       required by the applicable form, not later than the first use, authorized
       by the issuer after the opening of bids, of a prospectus relating to the
       securities offered at competitive bidding, unless no further public
       offering of such securities by the issuer and no reoffering of such
       securities by purchasers is proposed to be made.

         (D) Insofar as indemnification for liabilities arising under the
       Securities Act may be permitted to directors, officers and controlling
       persons of the registrants pursuant to the foregoing provisions, or
       otherwise, the registrants have been advised that in the opinion of the
       Securities and Exchange Commission such indemnification is against public
       policy as expressed in the Securities Act, and is, therefore,
       unenforceable.  In the event that a claim for indemnification against
       such liabilities (other than the payment by a registrant of expenses
       incurred or paid by a director, officer or controlling person of such
       registrant in the successful

                                      II-4
<PAGE>
 
       defense of any action, suit or proceeding) is asserted by such director,
       officer or controlling person in connection with the securities being
       registered, the applicable 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
       Securities Act and will be governed by the final adjudication of such
       issue.

                        ------------------------------------           
application or request by any Company, the Guarantor, any Owner Trustee or any
Loan Trustee to the Trustee to take any action under any provision of this Basic
Agreement or, in respect of the Certificates of any series, this Agreement, such
Company, the Guarantor, such Owner Trustee or such Loan Trustee, as the case may
be, shall furnish to the Trustee an Officer's Certificate stating that, in the
opinion of the signers, all conditions precedent (including any covenants
compliance with which constitutes a condition precedent), if any, provided for
in this Basic Agreement or, in respect of any Series, this Agreement relating to
the proposed action have been complied with and an Opinion of Counsel stating
that in the opinion of such counsel all such conditions precedent (including any
covenants compliance with which constitutes a condition precedent), if any, have
been complied with, except that in the case of any such application or request
as to which the furnishing of such documents is specifically required by any
provision of this Basic Agreement or, in respect of any Series, this Agreement
relating to such particular application or request, no additional certificate or
opinion need be furnished.

          Every certificate or opinion with respect to compliance with a
condition or covenant provided for in this Basic Agreement or, in respect of the
Certificates of any series, this Agreement (other than a certificate provided
pursuant to Section 8.4(d)) shall include:

          (1) a statement that each individual signing such certificate or
     opinion has read such covenant or condition and the definitions in this
     Basic Agreement or this Agreement relating thereto;

          (2) a brief statement as to the nature and scope of the examination or
     investigation upon which the statements or opinions contained in such
     certificate or opinion are based;

          (3) a statement that, in the opinion of each such individual, he has
     made such examination or investigation as is necessary to enable him to
     express an informed opinion as to whether or not such covenant or condition
     has been complied with; and

                                       11
<PAGE>
 
          (4) a statement as to whether, in the opinion of each such individual,
     such condition or covenant has been complied with.

          Section 1.3.  Form of Documents Delivered to Trustee.  In any case
                        --------------------------------------              
where several matters are required to be certified by, or covered by an opinion
of, any specified Person, it is not necessary that all such matters be certified
by, or covered by the opinion of, only one such Person, or that they be so
certified or covered by only one document, but one such Person may certify or
give an opinion with respect to some matters and one or more other such Persons
as to other matters and any such Person may certify or give an opinion as to
such matters in one or several documents.

          Any Opinion of Counsel stated to be based on the opinion of other
counsel shall be accompanied by a copy of such other opinion.  Any certificate
or opinion of an officer of the Guarantor or any Company may be based, insofar
as it relates to legal matters, upon a certificate or opinion of, or
representations by, counsel, unless such officer knows, or in the exercise of
reasonable care should know, that the certificate or opinion or representations
with respect to the matters upon which his certificate or opinion is based are
erroneous.  Any such certificate or opinion of counsel may be based, insofar as
it relates to factual matters, upon a certificate or opinion of, or
representations by, an officer or officers of the Guarantor or Applicable
Company stating that the information with respect to such factual matters is in
the possession of such Company unless such counsel knows, or in the exercise of
reasonable care should know, that the certificate or opinion or representations
as to such matters are erroneous.

          Where any Person is required to make, give or execute two or more
applications, requests, consents, certificates, statements, opinions or other
instruments under this Basic Agreement or, in respect of the Certificates of any
series, this Agreement, they may, but need not, be consolidated and form one
instrument.

          Section 1.4.  Acts of Certificateholders.  (a)  Any direction,
                        --------------------------                      
consent, waiver or other action provided by this Agreement in respect of the
Certificates of any series to be given or taken by Certificateholders may be
embodied in and evidenced by one or more instruments of substantially similar
tenor signed by such Certificateholders in person or by an agent or proxy duly
appointed in writing; and, except as herein otherwise expressly provided, such
action shall become effective when such instrument or instruments are delivered
to the Trustee and, where it is hereby expressly required pursuant to this
Agreement, to the Applicable Company or any Loan Trustee. Such instrument or
instruments (and the action embodied therein and evidenced thereby) are herein
sometimes referred to as the "Act" of the Certificateholders signing such
instrument or instruments.  Proof of execution of any such instrument or of a
writing appointing any such agent shall be sufficient for any purpose of this
Agreement and conclusive in favor of the Trustee, the Guarantor, the Applicable
Company and the related Loan Trustee, if made in the manner provided in this
Section.

          (b) The fact and date of the execution by any Person of any such
instrument or writing may be proved by the certificate of any notary public or
other officer of any

                                       12
<PAGE>
 
jurisdiction authorized to take acknowledgments of deeds or administer oaths
that the Person executing such instrument acknowledged to him the execution
thereof, or by an affidavit of a witness to such execution sworn to before any
such notary or such other officer and where such execution is by an officer of a
corporation or association or a member of a partnership, on behalf of such
corporation, association or partnership, such certificate or affidavit shall
also constitute sufficient proof of his authority.  The fact and date of the
execution of any such instrument or writing, or the authority of the Person
executing the same, may also be proved in any other reasonable manner which the
Trustee deems sufficient.

          (c) In determining whether the Certificateholders of the requisite
Fractional Undivided Interests of Certificates of any series Outstanding have
given any direction, consent or waiver (a "Direction"), under this Agreement,
Certificates owned by the Guarantor, any  Company, any related Owner Trustee,
any related Owner Participant or any Affiliate of any such Person shall be
disregarded and deemed not to be Outstanding for purposes of any such
determination.  In determining whether the Trustee shall be protected in relying
upon any such Direction, only Certificates that the Trustee knows to be so owned
shall be so disregarded.  Notwithstanding the foregoing, (i) if any such Person
owns 100% of the Certificates of any series Outstanding, such Certificates shall
not be so disregarded as aforesaid, and (ii) if any amount of Certificates of
such series so owned by any such Person have been pledged in good faith, such
Certificates shall not be disregarded as aforesaid if the pledgee establishes to
the satisfaction of the Trustee the pledgee's right so to act with respect to
such Certificates and that the pledgee is not the Guarantor, or a Company, any
related Owner Trustee, any related Owner Participant or any Affiliate of any
such Person.

          (d) The Applicable Company may at its option by delivery of an
Officer's Certificate to the Trustee set a record date to determine the
Certificateholders in respect of the Certificates of any series entitled to give
any consent, request, demand, authorization, direction, notice, waiver or other
action.  Notwithstanding Section 316(c) of the Trust Indenture Act, such record
date shall be the record date specified in such Officer's Certificate, which
shall be a date not more than 15 days prior to the first solicitation of
Certificateholders in connection therewith.  If such a record date is fixed,
such consent, request, demand, authorization, direction, notice, waiver or other
action may be given before or after such record date, but only the
Certificateholders of record of the applicable series at the close of business
on such record date shall be deemed to be Certificateholders for the purposes of
determining whether Certificateholders of the requisite proportion of
Outstanding Certificates of such series have authorized or agreed or consented
to such consent, request, demand, authorization, direction, notice, waiver or
other action, and for that purpose the Outstanding Certificates of such series
shall be computed as of such record date; provided that no such consent,
                                          --------                      
request, demand, authorization, direction, notice, waiver or other action by the
Certificateholders on such record date shall be deemed effective unless it shall
become effective pursuant to the provisions of this Agreement not later than one
year after the record date.

          (e) Any request, demand, authorization, notice, direction, consent,
waiver or other action by the Certificateholder of any Certificate shall bind
the Certificateholder of every

                                       13
<PAGE>
 
Certificate issued upon the transfer thereof or in exchange therefor or in lieu
thereof, whether or not notation of such action is made upon such Certificate.

          (f) Except as otherwise provided in Section 1.4(c), Certificates of
any series owned by or pledged to any Person shall have an equal and
proportionate benefit under the provisions of this Agreement, without
preference, priority, or distinction as among all of the Certificates of such
series.


                                   ARTICLE II

                       ORIGINAL ISSUANCE OF CERTIFICATES;

                        ------------------------------------           
aggregate principal amount of Certificates that may be authenticated and
delivered under this Basic Agreement is unlimited.  The Certificates may be
issued from time to time in one or more series and shall be designated generally
as the "Pass Through Certificates", with such further designations added or
incorporated in such title for the Certificates of each series as specified in
the related Trust Supplement.  Each Certificate shall bear upon its face the
designation so selected for the series to which it belongs.  All Certificates of
the same series shall be substantially identical except that the Certificates of
a series may differ as to denomination and as may otherwise be provided in the
Trust Supplement establishing the Certificates of such series.  Each series of
Certificates issued pursuant to this Agreement will evidence Fractional
Undivided Interests in the related Trust and will have no rights, benefits or
interests in respect of any other Trust or the Trust Property held therein.  All
Certificates of the same series shall be in all respects equally and ratably
entitled to the benefits of this Agreement without preference, priority or
distinction on account of the actual time or times of authentication and
delivery, all in accordance with the terms and provisions of this Agreement.

          (b) The following matters shall be established with respect to the
Certificates of each series issued hereunder by a Trust Supplement executed and
delivered by and among the Guarantor, the Applicable Company and the Trustee:

          (1) the formation of the Trust as to which the Certificates of such
     series represent Fractional Undivided Interests and its designation (which
     designation shall distinguish such Trust from each other Trust created
     under this Basic Agreement and a Trust Supplement);

          (2) the specific designation and title of the Certificates of such
     series (which title shall distinguish the Certificates of such series from
     each other series of Certificates created under this Basic Agreement and a
     Trust Supplement);

                                       14
<PAGE>
 
          (3) any limit upon the aggregate principal amount of the Certificates
     of such series that may be authenticated and delivered (which limit shall
     not pertain to Certificates authenticated and delivered upon registration
     of transfer of, or in exchange for, or in lieu of, other Certificates of
     the series pursuant to Sections 3.3, 3.4 and 3.5);

          (4) the Cut-off Date with respect to the Certificates of such series
     and the related Trust;

          (5) the Regular Distribution Dates applicable to the Certificates  of
     such  series and the related Trust;

          (6) the Special Distribution Dates applicable to the  Certificates  of
     such  series and the related Trust;

          (7) if other than as provided in  Section 3.4 or 7.11(b),  the
     Registrar  or  the  Paying Agent for the Certificates of such series,
     including  any  Co-Registrar  or  additional  Paying Agent;

          (8) if other than as provided in Section 3.1, the denominations in
     which the Certificates of such series shall be issuable and, if other than
     United States dollars, the currency or currencies (including currency
     units) thereof;

          (9) the specific form of the Certificates of such series (including
     the interest rate applicable thereto) and whether or not Certificates of
     such series are to be issued as Book-Entry Certificates and, if such
     Certificates are to be Book-Entry Certificates, the form of Letter of
     Representations, if any;

          (10) a description of the related Secured Notes to be acquired and
     held in the related Trust and of the related Property and the related Note
     Documents, including whether or not such Secured Notes are senior or
     subordinate to any other Secured Notes and if so, the terms and conditions
     pursuant to which such Secured Notes are senior to or subordinate to other
     Secured Notes or other debt secured by the Property;

          (11) provisions with respect to the terms for which the definitions
     set forth in Article I hereof or the terms of Section 9.1 hereof permit or
     require further specification in the related Trust Supplement;

          (12) any restrictions (including legends) in respect of ERISA;

          (13) whether such series will be subject to any intercreditor
     agreement, liquidity or credit facility or other agreement or instrument;

          (14) any other terms of the Certificates of such series (which terms
     shall not be inconsistent with the provisions of the Trust Indenture Act),
     including any terms that

                                       15
<PAGE>
 
     may be required or advisable under United States laws or regulations or
     advisable in connection with the marketing of Certificates of such series;

          (15) the extent, if any, to which the Guarantor or the Applicable
     Company may acquire Certificates and deliver such Certificates or cash to
     the respective Trusts and obtain the release of Secured Notes held by such
     Trusts; and

          (16) whether the Certificates are issuable as bearer instead of
     registered Certificates or both, and the terms upon which bearer
     Certificates may be exchanged for registered Certificates.

          (c) At any time and from time to time after the execution and delivery
of this Basic Agreement and a Trust Supplement forming a Trust and establishing
the terms of Certificates of a series, Certificates of such series shall be
executed, authenticated and delivered by the Trustee to the Person or Persons
specified by the Applicable Company upon request of the Applicable Company and
upon satisfaction of any conditions precedent set forth in such Trust Supplement
or in any other document to which a Trustee is a party relating to the issuance
of the Certificates of such series.

          Section 2.2.  Acquisition of Secured Notes.  (a)  Unless otherwise
                        ----------------------------                        
specified in the related Trust Supplement, on or prior to the Issuance Date of
the Certificates of a series, the Trustee shall execute and deliver the related
Note Purchase Agreements in the forms delivered to the Trustee by the Applicable
Company.  The Trustee shall issue and sell such Certificates, in authorized
denominations and in such Fractional Undivided Interests, so as to result in the
receipt of consideration in an amount equal to the aggregate purchase price of
Secured Notes to be held in the applicable Trust as specified in the related
Note Purchase Agreements and, concurrently therewith, the Trustee shall
purchase, pursuant to the terms and conditions of such Note Purchase Agreements,
the Secured Notes (except Postponed Notes, if any) at a purchase price equal to
the amount of such consideration so received.  Except as provided in Sections
3.3, 3.4 and 3.5 hereof, the Trustee shall not execute, authenticate or deliver
Certificates of such series in excess of the aggregate amount specified in this
paragraph.  The provisions of this Subsection (a) are subject to the provisions
of Subsection (b) below.

           (b) If on or prior to the Issuance Date with respect to a series of
Certificates the Applicable Company shall deliver to the Trustee a Postponement
Notice relating to one or more Postponed Notes, the Trustee shall postpone the
purchase of such Postponed Notes and shall deposit into an escrow account (as to
such Trust, the "Escrow Account") to be maintained as a part of the related
Trust an amount equal to the purchase price of such Postponed Notes (the
"Escrowed Funds").  The Escrowed Funds so deposited shall be (i) invested by the
Trustee at the direction and risk of the Applicable Company in Specified
Investments or (ii) if provided in the Trust Supplement relating to such series
of Certificates and subject to the terms and conditions set forth therein,
invested in debt instruments of the Guarantor or the Applicable Company (and
guaranteed by the Guarantor), in each case (x) maturing no later than any
scheduled Transfer Date relating to such series of Certificates, or (y) if no
such Transfer Date

                                       16
<PAGE>
 
has been scheduled, maturing on the next Business Day, or (z) if subsequent to
the giving of the applicable Postponement Notice the Applicable Company has
given notice to the Trustee that any Postponed Notes will not be issued,
thereafter with respect to the portion of the Escrowed Funds relating to such
Postponed Notes, maturing on or before the next applicable Special Distribution
Date, if such investments are reasonably available for purchase.  The Trustee
shall make withdrawals from the Escrow Account only as provided in this
Agreement.  Upon request of the Applicable Company on one or more occasions and
the satisfaction of the closing conditions specified in the applicable Note
Purchase Agreements on or prior to the related Cut-off Date, the Trustee shall
purchase the applicable Postponed Notes with the Escrowed Funds withdrawn from
the Escrow Account.

          The Trustee shall hold all Specified Investments until the maturity
thereof and will not sell or otherwise transfer Specified Investments.  If
Specified Investments held in an Escrow Account mature prior to any applicable
Transfer Date, any proceeds received on the maturity of such Specified
Investments (other than any earnings thereon) shall be reinvested by the Trustee
at the direction and risk of, and for the benefit of, the Applicable Company in
Specified Investments maturing as provided in the preceding paragraph.
    
          Any earnings on Specified Investments received from time to time by
the Trustee shall be distributed to the Applicable Company periodically upon its
demand, or if not so distributed, reinvested by the Trustee in Specified
Investments maturing as provided in the applicable Trust Supplement or in the
second preceding paragraph.  The Applicable Company shall pay to the Trustee for
deposit to the relevant Escrow Account an amount equal to any losses incurred on
such Specified Investments made at the direction and risk of such Applicable
Company.  On the Initial Regular Distribution Date in respect of the
Certificates of any series, the Applicable Company will pay (in immediately
available funds) to the Trustee an amount equal to the interest that would have
accrued on those Postponed Notes related to such Applicable Company, if any,
purchased after the Issuance Date as if such Postponed Notes had been purchased
on the Issuance Date, from the Issuance Date to, but not including, the date of
the purchase of such Postponed Notes by the Trustee, but only to the extent such
accrued interest would be payable on the next succeeding payment date, unless
otherwise specified in the related Trust Supplement.      

          If, in respect of the Certificates of any series, the Applicable
Company notifies the Trustee prior to the applicable Cut-off Date that any
Postponed Notes will not be issued on or prior to such Cut-off Date for any
reason, on the next Special Distribution Date for such Certificates occurring
more than 20 days following the date of such notice, unless otherwise specified
in the related Trust Supplement, (i) the Applicable Company shall pay to the
Trustee for deposit in the related Special Payments Account, in immediately
available funds, an amount equal to the interest that would have accrued on the
Postponed Notes related to such Applicable Company designated in such notice at
a rate equal to the interest rate applicable to such Certificates from the
Issuance Date to, but not including, such Special Distribution Date and (ii) the
Trustee shall transfer an amount equal to the sum of that amount of Escrowed
Funds that would have been used to purchase the Postponed Notes designated in
such notice plus the

                                       17
<PAGE>
 
amount paid by such Applicable Company pursuant to the immediately preceding
clause (i) to the related Special Payments Account for distribution as a Special
Payment in accordance with the provisions hereof.

          If, on such Cut-off Date, an amount equal to less than all of the
Escrowed Funds (other than Escrowed Funds referred to in the immediately
preceding paragraph) has been used to purchase Postponed Notes, on the next such
Special Distribution Date occurring more than 20 days following such Cut-off
Date, unless otherwise specified in the related Trust Supplement,  (i) the
Applicable Company shall pay to the Trustee for deposit in such Special Payments
Account, in immediately available funds, an amount equal to the interest that
would have accrued on such Postponed Notes related to such Applicable Company
contemplated to be purchased with such unused Escrowed Funds (other than
Escrowed Funds referred to in the immediately preceding paragraph) but not so
purchased at a rate equal to the interest rate applicable to such Certificates
from the Issuance Date to, but not including, such Special Distribution Date and
(ii) the Trustee shall transfer the sum of such unused Escrowed Funds plus the
amount paid by such Applicable Company pursuant to the immediately preceding
clause (i) to such Special Payments Account for distribution as a Special
Payment in accordance with the provisions hereof.

          If the Applicable Company shall fail to make any payment due under
this Section 2.2, the Guarantor agrees to make such payment in its place.

          Section 2.3.  Acceptance by Trustee.  The Trustee, upon the execution
                        ---------------------                                  
and delivery of a Trust Supplement creating a Trust and establishing a series of
Certificates, shall acknowledge its acceptance of all right, title, and interest
in and to the Secured Notes to be acquired pursuant to Section 2.2 hereof and
the Note Purchase Agreements and shall declare that the Trustee holds and will
hold such right, title, and interest, together with all other property
constituting the Trust Property of such Trust, for the benefit of all then
present and future Certificateholders of such series, upon the trusts herein and
in such Trust Supplement set forth.  By its payment for and acceptance of each
Certificate of such series issued to it under this Agreement, each initial
Certificateholder of such series as grantor of such Trust shall thereby join in
the creation and declaration of such Trust.

          Section 2.4.  Limitation of Powers.  Each Trust shall be constituted
                        --------------------                                  
solely for the purpose of making the investment in the Secured Notes provided
for in the related Trust Supplement, and, except as set forth in Section 2.2(b)
or otherwise in this Agreement, the Trustee shall not be authorized or empowered
to acquire any other investments or engage in any other activities and, in
particular, the Trustee shall not be authorized or empowered to do anything that
would cause such Trust to fail to qualify as a "grantor trust" for federal
income tax purposes (including as subject to this restriction, acquiring any
Property by bidding such Secured Notes or otherwise, or taking any action with
respect to any such Property once acquired).

                               THE CERTIFICATES

          Section 3.1.  Form, Denomination and Execution of Certificates.  The
                        ------------------------------------------------      
Certificates of each series shall be issued in registered form (except as
otherwise specified in the relevant Trust Supplement) without coupons and shall
be substantially in the form attached hereto as Exhibit A, with such omissions,
variations and insertions as are permitted by this Agreement, and may have such
letters, numbers or other marks of identification and such legends or
endorsements typed, printed, lithographed or engraved thereon, as may be
required to comply with the rules of any securities exchange on which such
Certificates may be listed or to conform to any usage in respect thereof, or as
may, consistently herewith, be prescribed by the Trustee or by the officer
executing such Certificates, such determination by said officer to be evidenced
by his signing the Certificates.

          Except as provided in Section 3.9, the definitive Certificates of such
series shall be typed, printed, lithographed or engraved or produced by any
combination of these methods or may be produced in any other manner permitted by
the rules of any securities exchange on which such Certificates may be listed,
all as determined by the officer executing such Certificates, as evidenced by
his execution of such Certificates.

          Except as otherwise provided in the related Trust Supplement, the
Certificates of each series shall be issued in minimum denominations of $1,000
or integral multiples thereof, except that one Certificate of such series may be
issued in a denomination of less than $1,000.

          The Certificates of each series shall be executed on behalf of the
Trustee by manual or facsimile signature of a Responsible Officer of the
Trustee.  Certificates of any series bearing the manual or facsimile signature
of an individual who was, at the time when such signature was affixed,
authorized to sign on behalf of the Trustee shall be valid and binding
obligations of the Trustee, notwithstanding that such individual has ceased to
be so authorized prior to the authentication and delivery of such Certificates
or did not hold such office at the date of such Certificates.  No Certificate of
any series shall be entitled to any benefit under this Agreement, or be valid
for any purpose unless there appears on such Certificate a certificate of
authentication substantially in the form set forth in Exhibit A hereto executed
by or on behalf of the Trustee by manual signature, and such certificate of
authentication upon any Certificate shall be conclusive evidence, and the only
evidence, that such Certificate has been duly authenticated and delivered
hereunder.  All Certificates of any series shall be dated on the date of their
authentication.

          Section 3.2. Authentication of Certificates.  The Trustee shall duly
                       ------------------------------                         
authenticate and deliver Certificates of each series in authorized denominations
equalling in the aggregate the aggregate principal amount of the Secured Notes
to be purchased by the Trustee pursuant to the related Note Purchase Agreements,
and evidencing the entire ownership of the related Trust.

          Section 3.3. Temporary Certificates.  Pending the preparation of
                       ----------------------                             
definitive Certificates of any series, the Trustee may execute, authenticate and
deliver temporary Certificates of such series that are printed, lithographed,
typewritten or otherwise produced, in any denomination, containing substantially
the same terms and provisions as set forth in Exhibit A hereto, except for such
appropriate insertions, omissions, substitutions and other variations relating
to their temporary nature as the officer executing such temporary Certificates
may determine, as evidenced by such officer's execution of such temporary
Certificates.

          If temporary Certificates of any series are issued, the Trustee will
cause definitive Certificates of such series to be prepared without unreasonable
delay.  After the preparation of definitive Certificates of such series, the
temporary Certificates shall be exchangeable for definitive Certificates upon
surrender of such temporary Certificates at the Corporate Trust Office of the
Trustee, or at the office or agency of the Trustee maintained in accordance with
Section 7.11, without charge to the Holder.  Upon surrender for cancellation of
any one or more temporary Certificates, the Trustee shall execute, authenticate
and deliver in exchange therefor definitive Certificates of like series, in
authorized denominations and of a like aggregate Fractional Undivided Interest.
Until so exchanged, such temporary Certificates shall in all respects be
entitled to the same benefits under this Agreement as definitive Certificates.

          Section 3.4.  Registration of Transfer and Exchange of Certificates.
                        -----------------------------------------------------  
The Trustee shall cause to be kept at the office or agency to be maintained by
it in accordance with the provisions of Section 7.11 a register (the "Register")
for each series of Certificates in which, subject to such reasonable regulations
as it may prescribe, the Trustee shall provide for the registration of
Certificates of such series and of transfers and exchanges of such Certificates
as herein provided.  The Trustee shall initially be the registrar (the
"Registrar") for the purpose of registering Certificates of each series and
transfers and exchanges of such Certificates as herein provided.

          Upon surrender for registration of transfer of any Certificate at the
Corporate Trust Office or such other office or agency, the Trustee shall
execute, authenticate and deliver, in the name of the designated transferee or
transferees, one or more new Certificates of like series, in authorized
denominations of a like aggregate Fractional Undivided Interest.

          At the option of a Certificateholder, Certificates may be exchanged
for other Certificates of like series, in authorized denominations and of a like
aggregate Fractional Undivided Interest, upon surrender of the Certificates to
be exchanged at the Corporate Trust Office or at any such office or agency.
Whenever any Certificates are so surrendered for exchange, the Trustee shall
execute, authenticate and deliver the Certificates that the Certificateholder
making the exchange is entitled to receive.  Every Certificate presented or
surrendered for registration of transfer or exchange shall be duly endorsed or
accompanied by a written instrument of transfer in form satisfactory to the
Trustee and the Registrar duly executed by the Certificateholder thereof or its
attorney duly authorized in writing.

                                       20

          No service charge shall be made to a Certificateholder for any
registration of transfer or exchange of Certificates, but the Trustee shall
require payment of a sum sufficient to cover any tax or governmental charge that
may be imposed in connection with any transfer or exchange of Certificates.

          All Certificates surrendered for registration of transfer or exchange
shall be cancelled and subsequently destroyed by the Trustee.

          Section 3.5.  Mutilated, Destroyed, Lost or Stolen Certificates.  If
                        -------------------------------------------------     
(a) any mutilated Certificate is surrendered to the Registrar, or the Registrar
receives evidence to its satisfaction of the destruction, loss or theft of any
Certificate, and (b) there is delivered to the Registrar and the Trustee such
security, indemnity or bond as may be required by them to save each of them
harmless, then, in the absence of notice to the Registrar or the Trustee that
such Certificate has been acquired by a bona fide purchaser, the Trustee shall
execute, authenticate and deliver, in exchange for or in lieu of any such
mutilated, destroyed, lost or stolen Certificate, a new Certificate or
Certificates of like series, in authorized denominations and of like Fractional
Undivided Interest.  In connection with the issuance of any new Certificate
under this Section 3.5, the Trustee shall require the payment of a sum
sufficient to cover any tax or other governmental charge that may be imposed in
relation thereto and any other expenses (including the fees and expenses of the
Trustee and the Registrar) connected therewith.  Any duplicate Certificate
issued pursuant to this Section 3.5 shall constitute conclusive evidence of the
appropriate Fractional Undivided Interest in the related Trust, as if originally
issued, whether or not the lost, stolen or destroyed Certificate shall be found
at any time.

          Section 3.6.  Persons Deemed Owners.  Prior to due presentation of a
                        ---------------------                                 
Certificate for registration of transfer, the Guarantor, the Applicable Company,
the Trustee, the Registrar, and any Paying Agent of the Trustee may treat the
Person in whose name any Certificate is registered on the Register as the owner
of such Certificate for the purpose of receiving distributions pursuant to
Section 4.2 and for all other purposes whatsoever, and neither the Guarantor,
the Applicable Company, the Trustee, the Registrar, nor any Paying Agent of the
Trustee shall be affected by any notice to the contrary.

          Section 3.7.  Cancellation.  All Certificates surrendered for payment
                        ------------                                           
or registration of transfer or exchange shall, if surrendered to any Person
party hereto or any agent of the Trustee other than the Registrar, be delivered
to the Registrar for cancellation.  No Certificates shall be authenticated in
lieu of or in exchange for any Certificates cancelled as provided in this
Section, except as expressly permitted by this Agreement.  All cancelled
Certificates held by the Registrar shall be destroyed and a certification of
their destruction delivered to the Trustee.

          Section 3.8.  Limitation of Liability.  All payments or distributions
                        -----------------------                                
made to Certificateholders of any series under this Basic Agreement and the
related Trust Supplement shall be made only from the Trust Property of the
related Trust and only to the extent that the Trustee shall have sufficient
income or proceeds from such Trust Property to make such

                                       21
<PAGE>
 
payments in accordance with the terms of Article IV of this Agreement.  Each
Certificateholder, by its acceptance of a Certificate, agrees that it will look
solely to the income and proceeds from the Trust Property of the related Trust
to the extent available for distribution to such Certificateholder as provided
in this Agreement.

          Nothing in this Agreement shall be construed as an agreement, or
otherwise creating an obligation, of the Guarantor or any Applicable Company to
pay any of the principal, premium, if any, and interest due from time to time
under the Secured Notes or in respect of the Certificates.  The Guarantor and
each Company are parties to this Agreement solely for purposes of meeting the
requirements of the Trust Indenture Act, and therefore shall not be liable
hereunder (except as otherwise expressly provided herein).

          Section 3.9.  Book-Entry and Definitive Certificates.  (a)  Except for
                        --------------------------------------                  
one Certificate of each series that may be issued in a denomination of less than
$1,000, the Certificates of any series may, at the sole option of the Applicable
Company, be issued in the form of one or more typewritten Certificates
representing the Book-Entry Certificates of such series, to be delivered to The
Depository Trust Company, the initial Clearing Agency, by, or on behalf of, the
Applicable Company.  In such case, the Certificates of such series delivered to
The Depository Trust Company shall initially be registered on the Register in
the name of CEDE & Co., the nominee of the initial Clearing Agency, and no
Certificate Owner will receive a definitive certificate representing such
Certificate Owner's interest in the Certificates of such series, except as
provided above and in Subsection (d) below.  As to the Certificates of any
series, except with respect to the one Certificate of such series that may be
issued in a denomination of less than $1,000, unless and until definitive, fully
registered Certificates of such series (the "Definitive Certificates") have been
issued pursuant to Subsection (d) below:

          (i) the provisions of this Section 3.9 shall be in full force and
     effect;

          (ii) the Guarantor, the Applicable Company, the Paying Agent, the
     Registrar and the Trustee may deal with the Clearing Agency for all
     purposes (including the making of distributions on the Certificates) as the
     authorized representative of the Certificate Owners;

          (iii)  to the extent that the provisions of this Section 3.9 conflict
     with any other provisions of this Agreement (other than the provisions of
     any Trust Supplement amending this Section 3.9 as permitted by this Basic
     Agreement), the provisions of this Section 3.9 shall control;

          (iv) the rights of Certificate Owners shall be exercised only through
     the Clearing Agency and shall be limited to those established by law and
     agreements between such Certificate Owners and the Clearing Agency
     Participants; and until Definitive Certificates are issued pursuant to
     Subsection (d) below, the Clearing Agency will make book-entry transfers
     among the Clearing Agency Participants and receive and transmit

                                       22
<PAGE>
 
     distributions of principal and interest and premium, if any, on the
     Certificates to such Clearing Agency Participants;

          (v) such Certificates of such series may be transferred in whole, but
     not in part, and in the manner provided in Section 3.4 by the Clearing
     Agency holding such Certificates to a nominee of such Clearing Agency or by
     such Clearing Agency to a successor Clearing Agency selected or approved by
     the Applicable Company upon notice to the Trustee or to a nominee of such
     successor Clearing Agency; and

          (vi) whenever this Agreement requires or permits actions to be taken
     based upon instructions or directions of Certificateholders of such series
     holding Certificates of such series evidencing a specified percentage of
     the Fractional Undivided Interests in the related Trust, the Clearing
     Agency shall be deemed to represent such percentage only to the extent that
     it has received instructions to such effect from Certificate Owners and/or
     Clearing Agency Participants owning or representing, respectively, such
     required percentage of the beneficial interest in Certificates of such
     series and has delivered such instructions to the Trustee.  The Trustee
     shall have no obligation to determine whether the Clearing Agency has in
     fact received any such instructions.

          (b) Except with respect to the one Certificate of each series that may
be issued in a denomination of less than $1,000, whenever notice or other
communication to the Certificateholders of such series is required under this
Agreement, unless and until Definitive Certificates shall have been issued
pursuant to Subsection (d) below, the Trustee shall give all such notices and
communications specified herein to be given to Certificateholders of such series
to the Clearing Agency and/or the Clearing Agency Participants, and shall make
available additional copies as requested by such Clearing Agency Participants.

          (c) Unless and until Definitive Certificates of a series are issued
pursuant to Subsection (d) below, on the Record Date prior to each applicable
Regular Distribution Date and Special Distribution Date, the Trustee will
request from the Clearing Agency a securities position listing setting forth the
names of all Clearing Agency Participants reflected on the Clearing Agency's
books as holding interests in the Certificates of such series on such Record
Date.  The Trustee shall mail to each such Clearing Agency Participant the
statements described in Section 4.3 hereof and will make available additional
copies as requested by such Clearing Agency Participant for forwarding by such
Clearing Agency Participant to Certificate Owners.

          (d) If with respect to the Book-Entry Certificates of any series (i)
the Applicable Company advises the Trustee in writing that the Clearing Agency
is no longer willing or able to properly discharge its responsibilities and the
Trustee or the Applicable Company is unable to locate a qualified successor or
(ii) the Applicable Company, at its option, advises the Trustee in writing of
its election to terminate the book-entry system through the Clearing Agency in
respect of the Certificates or (iii) after the occurrence of an Event of
Default, Certificate Owners of Book-Entry Certificates of such series evidencing
Fractional Undivided Interests aggregating not less than a majority in interest
in the related Trust advise the Applicable

                                       23
<PAGE>
 
Company, the Trustee and the Clearing Agency through the Clearing Agency
Participants in writing that the continuation of a book-entry system through the
Clearing Agency is no longer in the best interests of the Certificate Owners of
such series, then the Trustee shall notify all Certificate Owners of such
series, through the Clearing Agency, of the occurrence of such event and of the
availability of Definitive Certificates.  Upon surrender to the Trustee of all
the Certificates of such series held by the Clearing Agency, accompanied by
written registration instructions from the Clearing Agency for registration of
Definitive Certificates in the names of Certificate Owners of such series, the
Trustee shall execute, authenticate and deliver the Definitive Certificates of
such series pursuant to Section 3.4 in accordance with the instructions of the
Clearing Agency.  Neither the Guarantor, any Company, the Registrar, the Paying
Agent nor the Trustee shall be liable for any delay in delivery of such
instructions and may conclusively rely on, and shall be protected in relying on,
such registration instructions.  Upon the authentication and delivery of
Definitive Certificates of such series, the Trustee shall recognize the Persons
in whose name the Definitive Certificates are registered in the Register as
Certificateholders hereunder.  None of the Applicable Company, the Guarantor and
the Trustee shall be liable if the Trustee or the Applicable Company is unable
to locate a qualified successor Clearing Agency.

          (e) Except as otherwise provided in the related Trust Supplement, the
Trustee shall enter into the applicable Letter of Representations with respect
to such series of Certificates and fulfill its responsibilities thereunder.

          (f) The provisions of this Section 3.9 may be made inapplicable to any
series or may be amended with respect to any series in the related Trust
Supplement.

The Trustee shall hold the Certificate Account in trust for the benefit of the
Certificateholders of such series, and shall make or permit withdrawals

receipt of the payment of the Scheduled Payments due on the Secured Notes held

record of such series on the Record Date with respect to such Regular
Distribution Date (other than as provided in Section 11.1 concerning the final

          (b) On each Special Distribution Date with respect to any Special
Payment with respect to a series of Certificates or as soon thereafter as the
Trustee has confirmed receipt of such Special Payment due on the Secured Notes
held in the related Trust or realized upon the sale of any such Secured Notes,
the Trustee shall distribute out of the applicable Special Payments Account the
entire amount deposited therein pursuant to Section 4.1(b) of such Special
Payment.  There shall be so distributed to each Certificateholder of record of
such series on the Record Date with respect to such Special Distribution Date
(other than as provided in Section 11.1 concerning the final distribution) by
check mailed to such Certificateholder at the address appearing in the Register
such Certificateholder's pro rata share (based on the aggregate Fractional
Undivided Interest in the related Trust held by such Certificateholder) of the
aggregate amount in the applicable Special Payments Account on account of such
Special Payment.

          (c) The Trustee shall, at the expense of the Applicable Company, cause
notice of each Special Payment with respect to a series of Certificates to be
mailed to each Certificateholder of such series at its address as it appears in
the Register.  In the event of redemption or purchase of Secured Notes held in
the related Trust, such notice shall be mailed

                                       25

be distributed.  In the case of any other Special Payments, such notice shall be
mailed as soon as practicable after the Trustee has confirmed that it has
received funds for such Special Payment.  Notices mailed by the Trustee shall
set forth:

          (i) the Special Distribution Date and the Record Date therefor (except
     as otherwise provided in Section 11.1),

          (ii) the amount of the Special Payment for each $1,000 face amount

     Distribution Date for the Certificates of such series, the total amount to
     be received on such date for each $1,000 face amount Certificate.

If the amount of premium, if any, payable upon the redemption or purchase of a
Secured Note has not been calculated at the time that the Trustee mails notice
of a Special Payment, it shall be sufficient if the notice sets forth the other
amounts to be distributed and states that any premium received will also be
distributed.

          If any redemption or purchase of the Secured Notes held in any Trust
is cancelled, the Trustee, as soon as possible after learning thereof, shall
cause notice thereof to be mailed to each Certificateholder of the related
series at its address as it appears on the Register.

Certificateholders of record of the related series on the Record Date with
respect to such Regular Distribution Date or Special Distribution Date a

year but not later than the latest date permitted by law, the Trustee shall
furnish to each Person who at any time during such calendar year was a
Certificateholder of record a statement containing the sum of the amounts
determined pursuant to clauses (a)(i) and (a)(ii) with respect to the related
Trust for such calendar year or, in the event such Person was a
Certificateholder of record during a portion of such calendar year, for the
applicable portion of such year, and such other items as are readily available
to the Trustee and that a Certificateholder shall reasonably request as
necessary for the purpose of such Certificateholder's preparation of its Federal
income tax returns.

applicable Special Distribution Date and the Trustee shall hold any such
Permitted Investments until maturity.  The Trustee shall have no liability with
respect to any investment made pursuant to this Section 4.4, other than by
reason of the willful misconduct or negligence of the Trustee.  All income and
earnings from such investments shall be distributed on such Special Distribution
Date as part of such Special Payment.

the reasonable judgment of the Trustee, such action shall not be adverse to the
best interests of the Certificateholders of the applicable series.

premium, if any, or interest on any Secured Note held in a Trust when due and
payable, then the Trustee, in its own name, and as trustee of an express trust,
as holder of such Secured Notes, shall be, to the extent permitted by and in
accordance with the terms of the applicable Note Documents, entitled and
empowered to institute any suits, actions or proceedings at law, in equity or
otherwise, for the collection of the sums so due and unpaid on such Secured
Notes and may prosecute any such claim or proceeding to judgment or final decree

                        -----------------------------                          
the Certificateholders holding Certificates evidencing Fractional Undivided

proceeding for any remedy available to the Trustee with respect to such Trust,
or exercising any trust or power conferred on the Trustee under this Agreement,
including any right of the Trustee as holder of the related Secured Notes held
in such Trust, provided that:
               --------      

          (1) such direction shall not be in conflict with any rule of law or
     with this Agreement or the terms of the applicable Note Documents and would
     not involve the Trustee in personal liability or expense,

          (2) the Trustee shall not determine that the action so directed would
     be unjustly prejudicial to the Certificateholders of such series not taking
     part in such direction,

          (3) the Trustee may take any other action permitted by this Agreement
     deemed proper by the Trustee that is not inconsistent with such direction,
     and

          (4) if an Indenture Event of Default under a related Indenture shall
     have occurred and be continuing, such direction shall not obligate the
     Trustee to vote more than a corresponding majority of the related Secured
     Notes held by the Trust in favor of directing any action by the related
     Loan Trustee with respect to such Indenture Event of Default.

          Section 6.5.  Waiver of Past Defaults.  The Certificateholders holding

Trust Supplement with respect to such series and its consequences, except a
default:

          (1) in the deposit of any Scheduled Payment or Special Payment under
     Section 4.1 or in the distribution of any payment under Section 4.2 on the
     Certificates of such series, or

          (2) in the payment of the principal of (premium, if  any) or interest
     on the Secured Notes, or

          (3) in respect of a covenant or provision hereof that under Article IX
     hereof cannot be modified or amended without the consent of each
     Certificateholder holding an Outstanding Certificate of such series
     affected.

          Upon any such waiver, such default shall cease to exist with respect
to the Certificates of such series and any Event of Default arising therefrom
shall be deemed to have been cured for every purpose in respect of such series
and any direction given by the Trustee on behalf of the Certificateholders of
such series to the relevant Loan Trustee shall be annulled with respect thereto;
but no such waiver shall extend to any subsequent or other default or Event of
Default or impair any right consequent thereon.  Upon any such waiver, the
Trustee shall vote the Secured Notes issued under the relevant Indenture held in
the applicable Trust to waive the corresponding Indenture Event of Default (and,
if applicable, the corresponding Lease default).

Distribution Date, shall not be impaired or affected without the consent of such
Certificateholder.

Certain Conditions.  A Certificateholder of any series shall not have the right

with respect to this Agreement, for the appointment of a receiver or for the
enforcement of any other remedy under this Agreement, unless:

          (1) such Certificateholder previously shall have given written notice
     to the Trustee of a continuing Event of Default;

          (2) the Certificateholders holding Certificates of such series
     evidencing Fractional Undivided Interests aggregating not less than 25% of
     the related Trust shall

     to the Trustee during such 60-day period by the Certificateholders holding
     Certificates of such series evidencing Fractional Undivided Interests
     aggregating not less than a majority in interest in the related Trust.

such series to (i) surrender, impair, waive, affect, disturb or prejudice any
property in the Trust Property of the related Trust or the lien of any related
Indenture on any property subject thereto, or the rights of the
Certificateholders of such series or the holders of the related Secured Notes,

Agreement, or in any suit, action or proceeding against the Trustee for any
action taken or omitted by it as Trustee hereunder, the filing by any party
litigant in such suit, action or proceeding of an undertaking to pay the costs
of such suit, action or proceeding, and that such court may, in its discretion,
assess reasonable costs, including reasonable attorneys' fees, against any party
litigant in such suit, action or proceeding, having due regard to the merits and
good faith of the claims or defenses made by such party litigant; provided,
                                                                  --------

Applicable Company, the Guarantor, any related Owner Trustees, the related Loan
Trustees and the Certificateholders holding Certificates of the related series
in accordance with Section 313(c) of the Trust Indenture Act, notice of such

payment of money, the Trustee shall not give such notice until the earlier of
the time at which such default becomes an Event of Default and the expiration of
60 days from the occurrence of such default; provided, however, that, except in
                                             --------  -------

interest on any Secured Note, the Trustee shall be protected in withholding such
notice if and so long as the board of directors, the executive committee or a

respect of any Trust, the term "default" means any event that is, or after
notice or lapse of time or both would become, an Event of Default in respect of

     Fractional Undivided Interests aggregating not less than a majority in
     interest in the related Trust relating to the time, method and place of

     against such risk is not reasonably assured to it;

          (j) except during the continuance of an Event of Default, the Trustee
     undertakes and shall be responsible to perform only such duties as are
     specifically set forth herein and no implied covenants or obligations shall

     reasonable compensation for all services rendered by it hereunder (which
     compensation shall not be limited by any provision of law with regard to
     the compensation of a trustee of an express trust);

          (2) except as otherwise expressly provided herein or in any Trust
     Supplement, to reimburse, or cause to be reimbursed, the Trustee upon its
     request for all reasonable out-of-pocket expenses, disbursements and

     imposition of any such tax.  The Trustee, in its individual capacity, shall
     notify the Guarantor and the Applicable Company promptly of any tax for
     which it may seek indemnity.  The Guarantor or the Applicable Company
     shall, if it so elects, defend against the imposition of such tax and the
     Trustee, in its individual capacity, shall cooperate in the defense.  The
     Trustee, in its individual capacity, may have separate counsel with the

No resignation or removal of the Trustee and no appointment of a successor
Trustee of any Trust pursuant to this Article shall become effective until the
acceptance of appointment by the successor Trustee under Section 7.9.

          (b) The Trustee may resign at any time as trustee of any or all Trusts
by giving written notice thereof to the Guarantor, each Company, the Authorized
Agents, the related Owner Trustees, if any, and the related Loan Trustees.  If
an instrument of acceptance by a successor Trustee shall not have been delivered
to the Guarantor, each Company, the related Owner Trustees, if any, the related
Loan Trustees and the Trustee within 30 days after the giving of such notice of
resignation, the Guarantor, any Company or the resigning Trustee may petition
any court of competent jurisdiction for the appointment of a successor Trustee.

          (c) The Trustee may be removed at any time as trustee of any Trust by
Act of the Certificateholders of the related series holding Certificates of such
series evidencing Fractional Undivided Interests aggregating not less than a
majority in interest in such Trust delivered to the Trustee and to the
Guarantor, each Company, the related Owner Trustees and the related Loan
Trustees.

          (d) If at any time in respect of any Trust:

          (1) the Trustee shall fail to comply with Section 310 of the Trust
     Indenture Act after written request therefor by the Guarantor, any Company
     or by any Certificateholder of the related series who has been a bona fide
     Certificateholder for at least six months; or

          (2) the Trustee shall cease to be eligible under Section 7.7 and shall
     fail to resign after written request therefor by the Guarantor, any Company
     or by any such Certificateholder; or

          (3) the Trustee shall become incapable of acting or shall be adjudged
     a bankrupt or insolvent or a receiver of the Trustee or of its property
     shall be appointed or any public officer shall take charge or control of
     the Trustee or of its property or affairs for the purpose of
     rehabilitation, conservation or liquidation;

                                       37
<PAGE>
 
then, in any such case, (i) the Guarantor or any Company may remove the Trustee
of such Trust or (ii) any Certificateholder of the related series who has been a
bona fide Certificateholder for at least six months may, on behalf of himself
and all others similarly situated, petition any court of competent jurisdiction
for the removal of the Trustee and the appointment of a successor Trustee of
such Trust.

          (e) If a Responsible Officer of the Trustee shall obtain actual
knowledge of an Avoidable Tax (as hereinafter defined) in respect of any Trust
that has been or is likely to be asserted, the Trustee shall promptly notify the
Guarantor and the Applicable Company and any related Owner Trustees and shall,
within 30 days of such notification, resign as Trustee of such Trust unless
within such 30-day period the Trustee shall have received notice that the
Guarantor or Applicable Company in its sole discretion has agreed to pay such
tax.  Provided that there is a corporation in a jurisdiction where there are no
Avoidable Taxes that is willing to act as Trustee and is eligible under Section
7.7, the Applicable Company shall promptly appoint a successor Trustee of such
Trust in a jurisdiction where there are no Avoidable Taxes.  As used herein, an
"Avoidable Tax" in respect of such Trust means a state or local tax:  (i) upon
(w) such Trust, (x) such Trust Property, (y) Certificateholders of such Trust or
(z) the Trustee for which the Trustee is entitled to seek reimbursement from the
Trust Property of such Trust, and (ii) which would be avoided if the Trustee
were located in another state, or jurisdiction within a state, within the United
States.  A tax shall not be an Avoidable Tax in respect of any Trust if the
Guarantor or any Applicable Company or any Owner Trustee shall agree to pay, and
shall pay, such tax.

          (f) If the Trustee shall resign, be removed or become incapable of
acting as trustee of any Trust, or if a vacancy shall occur in the office of the
Trustee of any Trust for any cause, the Applicable Company shall promptly
appoint a successor Trustee of such Trust.  If, within one year after such
resignation, removal or incapability, or other occurrence of such vacancy, a
successor Trustee of such Trust shall be appointed by Act of the
Certificateholders of the related series holding Certificates of such series
evidencing Fractional Undivided Interests aggregating not less than a majority
in interest in such Trust delivered to the Guarantor, the Applicable Company,
the related Owner Trustees, if any, the related Loan Trustee and the retiring
Trustee, the successor Trustee so appointed shall forthwith upon its acceptance
of such appointment, become the successor Trustee of such Trust and supersede
the successor Trustee of such Trust appointed as provided above.  If no
successor Trustee shall have been so appointed as provided above and accepted
appointment in the manner hereinafter provided, any Certificateholder who has
been a bona fide Certificateholder of the related series for at least six months
may, on behalf of himself and all others similarly situated, petition any court
of competent jurisdiction for the appointment of a successor Trustee of such
Trust.

          (g) The successor Trustee of a Trust shall give notice of the
resignation and removal of the Trustee and appointment of the successor Trustee
by mailing written notice of such event by first-class mail, postage prepaid, to
the Certificateholders of the related series as their names and addresses appear
in the Register.  Each notice shall include the name of such successor Trustee
and the address of its Corporate Trust office.

                        --------------------------------------                  
Trustee appointed hereunder shall execute, acknowledge and deliver to the
Guarantor and the Applicable Company and to the retiring Trustee with respect to
any or all Trusts an instrument accepting such appointment, and thereupon the
resignation or removal of the retiring Trustee with respect to such Trusts shall
become effective and such successor Trustee, without any further act, deed or
conveyance, shall become vested with all the rights, powers, trusts and duties
of the retiring Trustee; but, on request of the Guarantor, the Applicable
Company or the successor Trustee, such retiring Trustee shall execute and
deliver an instrument transferring to such successor Trustee all such rights,
powers and trusts of the retiring Trustee and shall duly assign, transfer and
deliver to such successor Trustee all property and money held by such retiring
Trustee in respect of such Trusts hereunder, subject nevertheless to its lien,
if any, provided for in Section 7.6 and all books and records, or true, correct
and complete copies thereof, held by such retiring Trustee in respect of such
Trusts hereunder.  Upon request of any such successor Trustee, the Guarantor,
the Applicable Company, the retiring Trustee and such successor Trustee shall
execute and deliver any and all instruments containing such provisions as shall
be necessary or desirable to transfer and confirm to, and for more fully and
certainly vesting in, such successor Trustee all such rights, powers and trusts.

          If a successor Trustee is appointed with respect to one or more (but
not all) Trusts, the Guarantor, the Applicable Companies, the predecessor
Trustee and each successor Trustee with respect to any Trust shall execute and
deliver a supplemental agreement hereto that shall contain such provisions as
shall be deemed necessary or desirable to confirm that all the rights, powers,
trusts and duties of the predecessor Trustee with respect to the Trusts as to
which the predecessor Trustee is not retiring shall continue to be vested in the
predecessor Trustee, and shall add to or change any of the provisions of this
Basic Agreement and the applicable Trust Supplements as shall be necessary to
provide for or facilitate the administration of the Trusts hereunder by more
than one Trustee, it being understood that nothing herein or in such
supplemental agreement shall be construed as an appointment or constitution of
such Trustees as co-Trustees of the same Trust and that each such Trustee shall
be Trustee of separate Trusts.

          No successor Trustee shall accept its appointment unless at the time
of such acceptance such successor Trustee shall be qualified and eligible under
this Article.

          Section 7.10.  Merger, Conversion, Consolidation or Succession to
                         --------------------------------------------------
Business.  Any corporation into which the Trustee may be merged or converted or
- --------                                                                       
with which it may be consolidated, or any corporation resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any
corporation succeeding to all or substantially all of the corporate trust
business of the Trustee, shall be the successor of the Trustee hereunder,
provided such corporation shall be otherwise qualified and eligible under this
Article, without the execution or filing of any paper or any further act on the
part of any of the parties hereto.

          In case any Certificates shall have been executed or authenticated,
but not delivered, by the Trustee then in office, any successor by merger,
conversion or consolidation

                                       39
<PAGE>
 
to such executing or authenticating Trustee may adopt such execution or
authentication and deliver the Certificates so executed or authenticated with
the same effect as if such successor Trustee had itself executed or
authenticated such Certificates.

          Section 7.11.  Maintenance of Agencies.  (a) With respect to each
                         -----------------------                           
series of Certificates unless otherwise provided in the applicable Trust
Supplement, there shall at all times be maintained in the Borough of Manhattan,
The City of New York, an office or agency where Certificates of such series may
be presented or surrendered for registration of transfer or for exchange, and
for payment thereof and where notices and demands to or upon the Trustee in
respect of such Certificates or of this Basic Agreement or the related Trust
Supplement may be served.  Such office or agency shall be initially at State
Street Bank and Trust Company, National Association, 61 Broadway, Concourse
Level, New York, New York.  Written notice of the location of each such other
office or agency and of any change of location thereof shall be given by the
Trustee to the Guarantor, each Applicable Company, any Owner Trustees, the Loan
Trustees and the Certificateholders of such series.  In the event that no such
office or agency shall be maintained or no such notice of location or of change
of location shall be given, presentations and demands may be made and notices
may be served at the Corporate Trust Office of the Trustee.

          (b) There shall at all times be a Registrar and a Paying Agent
hereunder with respect to the Certificates of each series.  Each such Authorized
Agent shall be a bank or trust company, shall be a corporation organized and
doing business under the laws of the United States or any state, with a combined
capital and surplus of at least $75,000,000, or a corporation the obligations of
which are guaranteed by a corporation organized and doing business under the
laws of the United States or any state, with a combined capital and surplus of
at least $75,000,000, and shall be authorized under such laws to exercise
corporate trust powers, subject to supervision by Federal or state authorities.
The Trustee shall initially be the Paying Agent and, as provided in Section 3.4,
Registrar hereunder with respect to the Certificates of each series.  Each
Registrar shall furnish to the Trustee and each Applicable Company, at stated
intervals of not more than six months, and at such other times as the Trustee or
such Applicable Company may request in writing, a copy of the Register
maintained by such Registrar.

          (c) Any corporation into which any Authorized Agent may be merged or
converted or with which it may be consolidated or any corporation resulting from
any merger, consolidation or conversion to which any Authorized Agent shall be a
party, or any corporation succeeding to the corporate trust business of any
Authorized Agent, shall be the successor of such Authorized Agent hereunder, if
such successor corporation is otherwise eligible under this Section, without the
execution or filing of any paper or any further act on the part of the parties
hereto or such Authorized Agent or such successor corporation.

          (d) Any Authorized Agent may at any time resign by giving written
notice of resignation to the Trustee, the Guarantor, each Applicable Company,
any related Owner Trustees and the related Loan Trustees.  The Applicable
Company may, and at the request of the Trustee shall, at any time terminate the
agency of any Authorized Agent by giving written notice of

                                       40
<PAGE>
 
termination to such Authorized Agent and to the Trustee.  Upon the resignation
or termination of an Authorized Agent or in case at any time any such Authorized
Agent shall cease to be eligible under this Section (when, in either case, no
other Authorized Agent performing the functions of such Authorized Agent shall
have been appointed), the Applicable Company shall promptly appoint one or more
qualified successor Authorized Agents, reasonably satisfactory to the Trustee,
to perform the functions of the Authorized Agent that has resigned or whose
agency has been terminated or who shall have ceased to be eligible under this
Section.  The Applicable Company shall give written notice of any such
appointment made by it to the Trustee, any related Owner Trustees and the
related Loan Trustees; and in each case the Trustee shall mail notice of such
appointment to all Certificateholders of the related series as their names and
addresses appear on the Register for such series.

          (e) The Guarantor and each Applicable Company agrees to pay, or cause
to be paid, from time to time to each Authorized Agent reasonable compensation
for its services and to reimburse it for its reasonable expenses.

          Section 7.12.  Money for Certificate Payments to Be Held in Trust.
                         --------------------------------------------------  
All moneys deposited with any Paying Agent for the purpose of any payment on
Certificates shall be deposited and held in trust for the benefit of the
Certificateholders entitled to such payment, subject to the provisions of this
Section.  Moneys so deposited and held in trust shall constitute a separate
trust fund for the benefit of the Certificateholders with respect to which such
money was deposited.

          The Trustee may at any time, for the purpose of obtaining the
satisfaction and discharge of this Agreement or for any other purpose, direct
any Paying Agent to pay to the Trustee all sums held in trust by such Paying
Agent, such sums to be held by the Trustee upon the same trusts as those upon
which such sums were held by such Paying Agent; and, upon such payment by any
Paying Agent to the Trustee, such Paying Agent shall be released from all
further liability with respect to such money.

          Section 7.13.  Registration of Secured Notes in Trustee's Name.  The
                         -----------------------------------------------      
Trustee agrees that all Secured Notes to be held in a Trust and Permitted
Investments, if any, shall be issued in the name of the Trustee as trustee for
the applicable Trust or its nominee and held by the Trustee, or, if not so held,
the Trustee or its nominee shall be reflected as the owner of such Secured Notes
or Permitted Investments, as the case may be, in the register of the issuer of
such Secured Notes or Permitted Investments.  In no event shall the Trustee
invest in, or hold, such Secured Notes or Permitted Investments in a manner that
would cause the Trustee not to have the ownership interest in such Secured Notes
or Permitted Investments under the applicable provisions of the Uniform
Commercial Code in effect where the Trustee holds such Secured Notes or
Permitted Investments or other applicable law then in effect.

          Section 7.14.  Representations and Warranties of Trustee.  The Trustee

          (ii) the Trustee has full power, authority and legal right to execute,
     deliver, and perform this Basic Agreement and has taken all necessary
     action to authorize the execution, delivery, and performance by it of this
     Basic Agreement;

          (iii)  the execution, delivery and performance by the Trustee of this
     Basic Agreement (a) will not violate any provision of any United States or
     Massachusetts law  or regulation governing the banking and trust powers of
     the Trustee or any order, writ, judgment or decree of any court, arbitrator
     or governmental authority applicable to the Trustee or any of its assets,
     (b) will not violate any provision of the Charter Documents or by-laws of
     the Trustee, and (c) will not violate any provision of, or constitute, with

     creation or imposition of any lien on any properties included in the Trust
     Property of any Trust pursuant to the provisions of any mortgage,
     indenture, contract, agreement or other undertaking to which it is a party,
     which violation, default or lien could reasonably be expected to have an
     adverse effect on the Trustee's performance or ability to perform its
     duties hereunder or thereunder or on the transactions contemplated herein
     or therein;

          (iv) the execution, delivery and performance by the Trustee of this
     Basic Agreement will not require the authorization, consent or approval of,
     the giving of notice to, the filing or registration with, or the taking of
     any other action in respect of, any United States or Massachusetts
     governmental authority or agency regulating the banking and corporate trust
     activities of the Trustee; and

          (v) this Basic Agreement has been duly executed and delivered by the
     Trustee and constitute the legal, valid, and binding agreements of the
     Trustee, enforceable against it in accordance with their terms, provided
     that enforceability may be limited by (i) applicable bankruptcy,
     insolvency, reorganization, moratorium or similar laws affecting the rights
     of creditors generally and (ii) general principles of equity.

          Section 7.15.  Withholding Taxes, Information Reporting. As to the
                         ----------------------------------------           
Certificates of any series, the Trustee, as trustee of the related grantor trust
created by this Agreement, shall exclude and withhold from each distribution of
principal, premium, if any, and interest and other amounts due under this
Agreement or under the Certificates of such series any and all withholding taxes
applicable thereto as required by law.  The Trustee agrees to act as such
withholding agent and, in connection therewith, whenever any present or future
taxes or similar charges are required to be withheld with respect to any amounts
payable in respect of the Certificates of such series, to withhold such amounts
and timely pay the same to the appropriate authority in the name of and on
behalf of the Certificateholders of such series, that it will file any necessary
withholding tax returns or statements when due, and that, as promptly as
possible after the payment thereof, it will deliver to each such
Certificateholder appropriate documentation showing the payment thereof,

time.  The Trustee agrees to file any other information reports as it may be
required to file under United States law.

capacity agrees that it will, in respect of each Trust created by this
Agreement, at its own cost and expense (and without right of indemnity
hereunder, including Section 7.6), promptly take any action as may be necessary
to duly discharge and satisfy in full any mortgage, pledge, lien, charge,
encumbrance, security interest or claim ("Trustee's Liens") on or with respect
to the Trust Property of such Trust that is attributable to the Trustee either
(i) in its individual capacity and that is unrelated to the transactions
contemplated by this Agreement, the related Note Purchase Agreements or the
related Note Documents, or (ii) as Trustee hereunder or in its individual
capacity and that arises out of acts or omissions that are not contemplated by
this Agreement.

terminate upon the distribution to all Holders of the Certificates of the series
of such Trust and the Trustee of all amounts required to be distributed to them

such Trust may surrender their Certificates to the Trustee for payment of the
final distribution and cancellation, shall be mailed promptly by the Trustee to
Certificateholders of such series not earlier than the minimum number of days
and not more than the maximum number of days specified therefor in the related
Trust Supplement preceding such final distribution.  Such notice in addition
shall specify (A) the Regular Distribution Date (or Special Distribution Date,
as the case may be) upon which the proposed final payment of the Certificates of

Certificates of such series, the Trustee shall cause to be distributed to
Certificateholders of such series amounts distributable on such Regular
Distribution Date (or Special Distribution Date, as the case may be) pursuant to
Section 4.2.

          In the event that all of the Certificateholders of such series shall
not surrender their Certificates for cancellation within six months after the
date specified in the above-mentioned written notice, the Trustee shall give a
second written notice to the remaining Certificateholders of such series to
surrender their Certificates for cancellation and receive the final distribution
with respect thereto.  In the event that any money held by the Trustee for the
payment of distributions on the Certificates of such series shall remain
unclaimed for two years (or such lesser time as the Trustee shall be satisfied,
after sixty days' notice from the Applicable Company, is one month prior to the
escheat period provided under applicable law) after the final distribution date
with respect thereto, the Trustee shall pay to each Loan Trustee the appropriate
amount of money relating to such Loan Trustee and shall give written notice
thereof to the related Owner Trustees, if any, the Guarantor and the Applicable
Company.

          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 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 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, in the [Borough of Manhattan, the City of New York],
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


                                      A-5
<PAGE>
 
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.

          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.

as conformed, photostat or other copies.

                Based upon the foregoing and subject to the matters hereinafter 
set forth, I am of the opinion that:

                1.      The Guarantor has been duly incorporated and is validly 
existing as a corporation in good standing under the laws of the State of 
Delaware.

                2.      Each Company has been duly incorporated and is validly 
existing as a corporation in good standing under the laws of the State of 
Delaware.

                3.      With respect to the Pass Through Certificates of each 
series, (i) each of the Guarantor and the applicable Company has full corporate 
power and authority to execute, deliver and perform its obligations under the 
Pass Through Trust Agreement and the Trust Supplement establishing the terms of 
the Pass Through Certificates of such series and forming the related trust, and 
(ii) the Pass Through Trust Agreement and such Trust Supplement have been duly 
authorized by the Guarantor and such Company, and when the Pass Through Trust 
Agreement and such Trust Supplement have been duly executed and delivered by the
Guarantor and such Company will



<PAGE>
 
constitute the legal, valid and binding obligations of the Guarantor and such 
Company enforceable in accordance with their respective terms.
 
                4.      With respect to each Guaranty, (i) the Guarantor has
full corporate power and authority to execute, deliver and perform its
obligations under such Guaranty, (ii) such Guaranty has been duly authorized by
the Guarantor, and (iii) when such Guaranty is duly executed and delivered by
the Guarantor the Guaranty will constitute the legal, valid and binding
obligation of the Guarantor enforceable in accordance with its terms. 

                5.       The Guarantor has duly authorized the taking of any and
all action necessary to carry out and give effect to the transactions
contemplated to be performed on its part by each Guaranty, the Pass Through
Trust Agreement and each Trust Supplement.

                6.       Each Company has duly authorized the taking of any and
all action necessary to carry out and give effect to the transactions
contemplated to be performed on its part by the Pass Through Trust Agreement and
each Trust Supplement.

                The opinions expressed in paragraph 3 and 4 above are qualified
to the extent that the enforceability of the rights and remedies set forth in 
each Guaranty, the Pass Through Trust Agreement and each Trust Supplement may be
limited by bankruptcy, insolvency or other similar laws affecting creditor's 
rights generally or by principles of equity.

                I am a member of the bars of the State of New York and The
Commonwealth of Virginia and am not an expert in and express no opinion as to
the laws of other jurisdictions other than the federal law of the United States
and the corporte law of the State of Delaware.
 
                I hereby consent to the filing of this opinion as an Exhibit to 
the Registration Statement and to the reference to my name in the Prospectus 
constituting a part of such Registration Statement under the heading "Legal
Opinions." In giving such consent, I do not thereby admit that I come within the
category of persons whose consent is required under Section 7 of the Securities

                RE: MOBIL CORPORATION
                    PASS THROUGH CERTIFICATES
                    --------------------------

Ladies and Gentlemen:
          
        We are acting as special counsel to State Street Bank and Trust Company,
individually ("SSB"), and as Pass Through Trustee (the "Pass Through Trustee")
under the Pass Through Trust Agreement (the "Agreement"), between Mobil
Corporation, Mobil Marine Finance Company I Inc., Mobil Marine Finance Company
II Inc., Mobil Lease Finance Company Inc., Mobil Chemical Finance (Texas) Inc.,
Mobil Chemical Finance (Louisiana) Inc., Mobil Petrorail Finance Inc., Mobil
Transport Finance Company Inc., Mobil Equipment Finance Company Inc.
(collectively, the "Mobil Affiliates") and the Pass Through Trustee. Pursuant to
the Agreement and as supplemented by a Trust Supplement, the Pass Through
Trustee will issue Pass Through Certificates, in an aggregate principal amount
of up to $650,000,000 ("Pass Through Certificates"), registered with the
Securities and Exchange Commission under the Securities Act of 1933, as amended
(the "1933 Act"), by a Registration Statement on Form S-3 (File No 333-13457),
as amended (the "Registration Statement"). Except as otherwise defined herein,
terms used herein shall have the meanings set forth in the Agreement. 

        Our representation of the Pass Through Trustee has been as special
counsel for the purposes stated above. As to all matters of fact (including
factual conclusions and characterizations and descriptions of purpose, intention
or other state of mind), we have relied entirely upon (i) the representations of
the parties set forth in the Operative Documents and (ii) certificates delivered
to us by the man-
<PAGE>
 
Mobil Corporation                       2                      November 12, 1996
 
agement of SSB and have assumed, without independent inquiry, the accuracy of
those representations and certificates.

  We have examined the Agreement, the Pass Through Certificates, the discussion
in the Prospectus, dated November 12, 1996, applicable to the issuance of the
Pass Through Certificates constituting part of the Registration Statement (the
"Prospectus") entitled "Certain Massachusetts Taxes," and originals or copies
certified or otherwise identified to our satisfaction, of other such records,
documents, certificates, or other instruments as we have deemed necessary or
advisable for the purposes of this opinion.

  We have assumed the genuineness of all signatures (other than those on behalf
of SSB and the Pass Through Trustee), the conformity to the originals of all
documents reviewed by us as copies, the authenticity and completeness of all
original documents reviewed by us in original or copy form and the legal
competence of each individual executing any document (other than on behalf of
SSB and the Pass Through Trustee).

  Each opinion set forth below relating to the enforceability of any agreement
or instrument against the Pass Through Trustee, is subject to the following
general qualifications:

          (i) as to any agreement to which the Pass Through Trustee, as
applicable, is a party, we assume that such agreement is the legal, valid and
binding obligation of each party (other than the Pass Through Trustee) thereto;

        (ii) the enforceability of any obligation of the Pass Through Trustee
may be limited by bankruptcy, insolvency, fraudulent conveyance, reorganization,
moratorium, marshalling and other similar laws and rules of law affecting the
enforcement generally of creditors
<PAGE>

Mobil Corporation                       3                    November 12, 1996


        rights and remedies (including such as may deny giving effect to
        waivers of debtors' or guarantors' rights); and

                (iii) the enforcement of any rights and the
        availability of any specific or equitable relief of any kind may in all
        cases be subject to an implied duty of good faith and to general
        principles of equity (regardless of whether such enforceability or
        relief is considered in a proceeding at law or in equity).

                Subject to the limitation set forth below, we have made such
        examination of law as we have deemed necessary for the purposes of this
        opinion. The opinions set forth in paragraphs 1 and 2 below are based on
        and limited to the Federal laws of the United States and the internal
        substantive laws of the States of New York and Massachusetts. The
        opinion set forth in paragraph 3 below is based on and limited to the
        internal substantive laws of the Commonwealth of Massachusetts. Insofar
        as the matters referred to herein relate to the laws of the State of New
        York, we have relied entirely upon the opinion of even date herewith of
        Debevoise & Plimpton and the opinions set forth herein are subject to
        each of the qualifications and assumptions contained in said opinion. No
        opinion is expressed herein as to the application or effect of federal
        securities laws or as to the securities or so-called "Blue Sky" laws of
        any state or other jurisdiction. In addition, no opinion is expressed as
        to matters governed by any law, statute, rule or regulation of the
        United States relating to the acquisition, ownership, registration, use,
        operation, maintenance, repair, replacement or sale of or the nature of
        the Leased Property.

                Based on and subject to the foregoing, we are of the
                opinion that:

                1. The execution, authentication, delivery and performance by
        the Pass Through Trustee of the Pass Through
<PAGE>

Mobil Corporation                       4                     November 12, 1996

Certificates and the Agreement have been duly authorized by SSB.      

        2.  With respect to the Pass Through Certificates, when (a) a Trust
Supplement shall have been duly authorized, executed and delivered by the Mobil
Affiliates and the Pass Through Trustee in accordance with the terms and
conditions of the Agreement, and (b) the Pass Through Certificates shall have
been duly executed, authenticated, issued and delivered by the Trustee and sold
as contemplated by each of the Registration Statement, a Prospectus, a
Prospectus Supplement, the Agreement and a Trust Supplement, assuming that the
terms of the Pass Through Certificates are in compliance with then applicable
law, (i) the Agreement as supplemented by said Trust Supplement will constitute
a valid and binding obligation of the Trustee enforceable against the Trustee in
accordance with its terms, and (ii) the Pass Through Certificates will be
validly issued and will be entitled to the benefits of the Agreement and said
Trust Supplement.

        3  The discussion in the Prospectus Supplement entitled "Certain
Massachusetts Taxes," insofar as it relates to statements of law or legal
conclusions, is correct in all material respects.

        We hereby consent to the filing of this opinion as an Exhibit to the
Registration Statement, to the use of our name in the second sentence of the
first paragraph under the caption "Certain Massachusetts Taxes" in the
Prospectus and to the reference to us under the caption "Legal Opinions" in the
Prospectus. In giving this consent, we do not thereby admit that we are in the
category of person whose consent is required under Section 7 of the 1933 Act or
the Rules and Regulations of the Securities and Exchange Commission.

                                              Very truly yours,
