If at any time  payment  under the  Agreement  is rescinded or must be otherwise
restored  or  returned  by  Counterparty  upon  the  insolvency,  bankruptcy  or
reorganization of MSCS or MSDW or otherwise,  MSDW's obligations  hereunder with

accrued  and  unpaid  interest  thereon  to the date of such  purchase,  without
premium,  but including any other amounts then due and payable to the Applicable
Certificateholders  under the Agreement, the Intercreditor Agreement, the Escrow
Agreement  or  any  Note  Document  or  on  or  in  respect  of  the  Applicable
Certificates;   PROVIDED,   HOWEVER,   that  no  such   purchase  of  Applicable
Certificates  shall be effective  unless the  purchaser(s)  shall certify to the
Trustee that  contemporaneously  with such purchase,  such purchaser(s) is (are)
purchasing, pursuant to the terms of the Agreement and the Other Agreements, (A)
in the case of any purchase of the  Applicable  Certificates  pursuant to clause

Applicable Certificates,  the Class A-2 Certificates,  the Class B Certificates,
the Class C-1 Certificates and the Class C-2 Certificates that are senior to the

Applicable  Certificates  referred to in the first sentence hereof shall be made
to an account or accounts designated by the Trustee and each such purchase shall
be   subject   to  the  terms  of  this   Section   4.01(b).   Each   Applicable

sell, assign, transfer and convey to the purchaser(s) thereof (without recourse,
representation  or  warranty  of any kind  except for its own acts),  all of the
right, title,  interest and obligation of such Applicable  Certificateholder  in
the Agreement,  the Escrow Agreement,  the Deposit Agreement,  the Intercreditor
Agreement,  the  Liquidity  Facility,  the  NPA,  the  Note  Documents  and  all
Applicable   Certificates   and  Escrow   Receipts   held  by  such   Applicable
Certificateholder  (excluding  all right,  title and  interest  under any of the
foregoing  to the extent  such right,  title or  interest is with  respect to an
obligation  not then due and payable as respects any action or inaction or state
of affairs  occurring prior to such sale) (and the purchaser shall assume all of
such Applicable Certificateholder's  obligations under the Agreement, the Escrow
Agreement,  the Deposit Agreement,  the Intercreditor  Agreement,  the Liquidity
Facility,  the NPA, the Note Documents and all such Applicable  Certificates and
Escrow Receipts),  (ii) if such purchase occurs after a record date specified in

such  distribution,  and  (iii) if such  purchase  occurs  after a  Record  Date
relating to any distribution and prior to or on the related  Distribution  Date,
forthwith  turn  over to the  purchaser(s)  of its  Applicable  Certificate  all
amounts, if any, received by it on account of such distribution.  The Applicable
Certificates  will be deemed to be purchased on the date payment of the purchase
price is made  notwithstanding the failure of the Applicable  Certificateholders
to deliver any Applicable  Certificates and, upon such a purchase,  (I) the only
rights of the  Applicable  Certificateholders  will be to deliver the Applicable
Certificates  to the  purchaser(s)  and  receive  the  purchase  price  for such
Applicable  Certificates  and (II) if the  purchaser(s)  shall so request,  such
Applicable Certificateholder will comply with all the provisions of Section 3.04
of the Basic Agreement to enable new Applicable Certificates to be issued to the
purchaser in such denominations as it shall request. All charges and expenses in
connection  with the issuance of any such new Applicable  Certificates  shall be
borne by the purchaser thereof.

                                  THE TRUSTEE

            Section 5.01. DELIVERY OF DOCUMENTS; DELIVERY DATES. (a) The Trustee
is hereby directed (i) to execute and deliver the Intercreditor  Agreement,  the
Escrow  Agreement and the NPA on or prior to the Issuance Date, each in the form
delivered  to the Trustee by the  Company,  and (ii)  subject to the  respective
terms  thereof,  to perform  its  obligations  thereunder.  Upon  request of the
Company and the  satisfaction or waiver of the closing  conditions  specified in
the Underwriting Agreement,  the Trustee shall execute,  deliver,  authenticate,
issue and sell Applicable  Certificates in authorized  denominations equaling in
the aggregate the amount set forth,  with respect to the  Applicable  Trust,  in
Schedule  I to  the  Underwriting  Agreement  evidencing  the  entire  ownership
interest in the  Applicable  Trust,  which amount  equals the maximum  aggregate
principal  amount of  Equipment  Notes  which may be  purchased  by the  Trustee
pursuant to the NPA. Except as provided in Sections 3.03, 3.04, 3.05 and 3.06 of
the Basic  Agreement,  the Trustee  shall not execute,  authenticate  or deliver
Applicable  Certificates  in excess of the  aggregate  amount  specified in this
paragraph.  The  provisions  of this Section  5.01(a)  supersede and replace the
first sentence of Section  3.02(a) of the Basic  Agreement,  with respect to the
Applicable Trust.

            (b) On or after the Issuance Date, the Company may deliver from time
      to time to the Trustee a Delivery Notice relating to one or more Equipment
      Notes.  After  receipt of a Delivery  Notice and in any case no later than
      one  Business  Day prior to a  Scheduled  Delivery  Date as to which  such
      Delivery  Notice relates (the  "APPLICABLE  DELIVERY  DATE"),  the Trustee
      shall (as and when specified in the Delivery  Notice)  instruct the Escrow
      Agent to  provide  a  Notice  of  Purchase  Withdrawal  to the  Depositary
      requesting  (A) the  withdrawal of one or more Deposits on the  Applicable
      Delivery Date in accordance with and to the extent  permitted by the terms
      of the Escrow  Agreement and the Deposit  Agreement and (B) the payment of
      all, or a portion,  of such  Deposit or Deposits in an amount equal in the
      aggregate to the purchase price of such Equipment Notes to or on behalf of
      the  Owner  Trustee  or the  Company,  as the  case may be,  issuing  such
      Equipment  Notes,  all as  shall  be  described  in the  Delivery  Notice;
      PROVIDED  that, if the Issuance Date is an Applicable  Delivery  Date, the
      Trustee shall not so instruct the Escrow Agent,  and the purchase price of
      such  Equipment  Notes shall be paid from a portion of the proceeds of the
      sale of the  Applicable  Certificates.  The  Trustee  shall  (as and  when
      specified in such Delivery Notice), subject to the conditions set forth in
      Section 2 of the NPA,  enter into and  perform its  obligations  under the
      Participation Agreement specified in such Delivery Notice (the "APPLICABLE
      PARTICIPATION AGREEMENT") and cause such certificates, documents and legal
      opinions  relating to the Trustee to be duly  delivered as required by the
      Applicable Participation Agreement. If at any time prior to the Applicable
      Delivery Date, the Trustee  receives a notice of postponement  pursuant to
      Section  1(e) or  1(f)  of the  NPA,  then  the  Trustee  shall  give  the
      Depositary  (with a copy to the Escrow Agent) a notice of  cancellation of
      such Notice of Purchase Withdrawal relating to such Deposit or Deposits on
      such  Applicable  Delivery  Date.  Upon  satisfaction  of  the  conditions
      specified  in the NPA  and the  Applicable  Participation  Agreement,  the
      Trustee shall purchase the applicable Equipment Notes with the proceeds of
      the  withdrawals of one or more Deposits made on the  Applicable  Delivery
      Date in accordance with the terms of the Deposit  Agreement and the Escrow

<PAGE>

      Agreement (or, if the Issuance Date is the  Applicable  Delivery Date with
      respect to such Applicable Participation Agreement,  from a portion of the
      proceeds of the sale of the Applicable  Certificates).  The purchase price
      of such Equipment Notes shall equal the principal amount of such Equipment
      Notes.  Amounts  withdrawn  from such Deposit or Deposits in excess of the
      purchase price of the Equipment  Notes or to the extent not applied on the
      Applicable  Delivery Date to the purchase  price of the  Equipment  Notes,
      shall be re-deposited by the Trustee with the Depositary on the Applicable
      Delivery Date in accordance with the terms of the Deposit  Agreement.  The
      provisions of this Section 5.01(b) supersede and replace the provisions of
      Section 2.02 of the Basic Agreement with respect to the Applicable  Trust,
      and all provisions of the Basic Agreement  relating to Postponed Notes and
      Section  2.02 of the Basic  Agreement  shall  not apply to the  Applicable
      Trust.

            (c) The Trustee  acknowledges its acceptance of all right, title and
      interest in and to the Trust  Property to be acquired  pursuant to Section
      5.01(b)  of  this   Trust   Supplement,   the  NPA  and  each   Applicable
      Participation  Agreement,  and  declares  that it holds and will hold such
      right,  title and  interest  for the  benefit  of all  present  and future
      Applicable   Certificateholders,   upon  the  trusts  set  forth  in  this
      Agreement.  By its acceptance of an Applicable  Certificate,  each initial
      Applicable Certificateholder,  as a grantor of the Applicable Trust, joins
      with the Trustee in the creation of the Applicable  Trust.  The provisions
      of this Section  5.01(c)  supersede and replace the  provisions of Section
      2.03 of the Basic Agreement, with respect to the Applicable Trust.

            Section  5.02.  WITHDRAWAL  OF  DEPOSITS.  If  any  Deposits  remain
outstanding  on the Business Day next  succeeding  the Cut-off Date, the Trustee
shall give the Escrow Agent  notice that the  Trustee's  obligation  to purchase
Equipment  Notes under the NPA has  terminated  and instruct the Escrow Agent to
provide a notice of Final Withdrawal to the Depositary substantially in the form
of Exhibit B to the Deposit Agreement (the "FINAL WITHDRAWAL NOTICE").

            Section 5.03. THE TRUSTEE. (a) Subject to Section 5.04 of this Trust
Supplement  and Section 7.15 of the Basic  Agreement,  the Trustee  shall not be
responsible  in any  manner  whatsoever  for or in respect  of the  validity  or
sufficiency  of this Trust  Supplement,  the Deposit  Agreement,  the NPA or the
Escrow  Agreement or the due  execution  hereof or thereof by the Company or the
other  parties  thereto  (other than the  Trustee),  or for or in respect of the
recitals and statements  contained herein or therein,  all of which recitals and
statements  are made  solely by the  Company,  except  that the  Trustee  hereby
represents and warrants that each of this Trust Supplement, the Basic Agreement,
each Applicable Certificate, the Intercreditor Agreement, the NPA and the Escrow
Agreement  has been  executed  and  delivered by one of its officers who is duly
authorized to execute and deliver such document on its behalf.

            (b)  Except as herein  otherwise  provided  and  except  during  the
      continuation  of an Event of Default in  respect of the  Applicable  Trust
      created hereby, no duties, responsibilities or liabilities are assumed, or
      shall be construed  to be assumed,  by the Trustee by reason of this Trust
      Supplement  other  than as set  forth in the  Agreement,  and  this  Trust
      Supplement  is executed and accepted on behalf of the Trustee,  subject to

      all the terms and conditions  set forth in the Agreement,  as fully to all
      intents as if the same were herein set forth at length.

      contemplated herein or therein;

            (c) the execution,  delivery and  performance by the Trustee of this

      Agreement, the NPA and the Note Documents to which it is or is to become a
      party have been, or will be, as applicable, duly executed and delivered by

                              TERMINATION OF TRUST

            Section  7.01.   TERMINATION  OF  THE  APPLICABLE   TRUST.  (a)  The
respective  obligations and responsibilities of the Company and the Trustee with
respect to the  Applicable  Trust  shall  terminate  upon the earlier of (A) the

immediately following sentence) to, and the Company shall direct the institution
that will serve as the Related  Trustee  under the Related  Pass  Through  Trust
Agreement  to,  execute and deliver the  Assignment  and  Assumption  Agreement,
pursuant  to which the Trustee  shall  assign,  transfer  and deliver all of the
Trustee's right, title and interest to the Trust Property to the Related Trustee
under the Related  Pass  Through  Trust  Agreement.  The Trustee and the Related
Trustee shall execute and deliver the Assignment  and Assumption  Agreement upon
the satisfaction of the following conditions:

            (i) The Trustee, the Related Trustee and each of the Rating Agencies
      then rating the Applicable  Certificates  shall have received an Officer's
      Certificate and an Opinion of Counsel dated the date of the Assignment and
      Assumption  Agreement and each satisfying the requirements of Section 1.02
      of the Basic Agreement, which Opinion of Counsel shall be substantially to
      the effect set forth below and may be relied upon by the Beneficiaries (as
      defined in the Assignment and Assumption Agreement):

            (I) Upon the execution and delivery  thereof by the parties  thereto
      in  accordance  with the  terms of this  Agreement  and the  Related  Pass
      Through Trust  Agreement,  the Assignment  and  Assumption  Agreement will
      constitute the valid and binding obligation of each of the parties thereto
      enforceable against each such party in accordance with its terms;

            (II)  Upon  the  execution  and  delivery  of  the   Assignment  and
      Assumption  Agreement in accordance  with the terms of this  Agreement and
      the  Related  Pass  Through  Trust  Agreement,   each  of  the  Applicable

      Related Pass Through Trust Agreement;

            (III) The  Related  Trust is not  required  to be  registered  as an
      investment company under the Investment Company Act of 1940, as amended;

<PAGE>

            (IV) The Related Pass Through Trust Agreement  constitutes the valid
      and binding obligation of the Company  enforceable  against the Company in
      accordance with its terms; and

            (V)  Neither  the  execution  and  delivery  of the  Assignment  and
      Assumption  Agreement in accordance  with the terms of this  Agreement and
      the Related Pass Through  Trust  Agreement,  nor the  consummation  by the
      parties  thereto  of  the  transactions  contemplated  to  be  consummated
      thereunder on the date thereof,  will violate any law or governmental rule
      or  regulation  of the State of New York or the  United  States of America
      known to such counsel to be applicable to the transactions contemplated by
      the Assignment and Assumption Agreement.

            (ii) The Trustee and the Company  shall have  received (x) a copy of
      the articles of incorporation  and bylaws of the Related Trustee certified
      as of the Transfer  Date by the  Secretary or Assistant  Secretary of such
      institution  and  (y) a copy  of the  filing  (including  all  attachments
      thereto) made by the  institution  serving as the Related Trustee with the
      Office of the Superintendent, State of New York Banking Department for the
      qualification  of the Related Trustee under Section 131(3) of the New York
      Banking Law.

Upon the execution of the  Assignment  and  Assumption  Agreement by the parties
thereto,   the   Applicable   Trust   shall  be   terminated,   the   Applicable
Certificateholders  shall receive  beneficial  interests in the Related Trust in
exchange for their interests in the Applicable  Trust equal to their  respective
beneficial  interests in the Applicable  Trust,  and the Outstanding  Applicable
Certificates representing Fractional Undivided Interests in the Applicable Trust
shall be deemed for all purposes of this  Agreement and the Related Pass Through
Trust Agreement,  without further signature or action of any party or Applicable
Certificateholder, to be certificates representing the same fractional undivided
interests in the Related  Trust and its trust  property.  By  acceptance  of its
Applicable  Certificate,  each  Applicable  Certificateholder  consents  to such
assignment,  transfer and  delivery of the Trust  Property to the trustee of the
Related Trust upon the execution and delivery of the  Assignment  and Assumption
Agreement.

            In connection  with the  occurrence of the event set forth in clause
(B) above,  notice of such  termination,  specifying the Distribution  Date upon
which  the  Applicable   Certificateholders   may  surrender  their   Applicable
Certificates  to  the  Trustee  for  payment  of  the  final   distribution  and
cancellation,   shall  be  mailed   promptly  by  the   Trustee  to   Applicable
Certificateholders not earlier than the 60th day and not later than the 15th day
next preceding such final Distribution Date specifying (A) the Distribution Date
upon which the proposed  final payment of the  Applicable  Certificates  will be
made upon presentation and surrender of Applicable Certificates at the office or
agency of the Trustee  therein  specified,  (B) the amount of any such  proposed
final  payment,  and (C) that  the  Record  Date  otherwise  applicable  to such
Distribution Date is not applicable,  payments being made only upon presentation
and  surrender  of the  Applicable  Certificates  at the office or agency of the
Trustee therein  specified.  The Trustee shall give such notice to the Registrar
at the  time  such  notice  is  given  to  Applicable  Certificateholders.  Upon
presentation  and surrender of the Applicable  Certificates  in accordance  with
such  notice,   the  Trustee  shall  cause  to  be   distributed  to  Applicable
Certificateholders such final payments.

<PAGE>

            In the event that all of the Applicable Certificateholders shall not
surrender their Applicable 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  Applicable  Certificateholders  to
surrender their  Applicable  Certificates for cancellation and receive the final
distribution  with respect thereto.  No additional  interest shall accrue on the
Applicable  Certificates  after the  Distribution  Date  specified  in the first
written notice.  In the event that any money held by the Trustee for the payment
of distributions on the Applicable  Certificates  shall remain unclaimed for two
years (or such lesser time as the Trustee shall be satisfied,  after sixty days'
notice from the 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, the Owner Participants and the Company.

            (b) The  provisions  of this Section 7.01  supersede and replace the
      provisions of Section 11.01 of the Basic  Agreement in its entirety,  with
      respect to the Applicable Trust.

                            MISCELLANEOUS PROVISIONS

            Section 8.01. BASIC AGREEMENT RATIFIED.  Except and so far as herein
expressly  provided,  all of the  provisions,  terms and conditions of the Basic
Agreement are in all respects  ratified and confirmed;  and the Basic  Agreement
and this Trust Supplement shall be taken, read and construed as one and the same
instrument.  All  replacements of provisions of, and other  modifications of the
Basic  Agreement set forth in this Trust  Supplement  are solely with respect to
the Applicable Trust.

            SECTION 8.02.  GOVERNING  LAW. THE AGREEMENT AND, UNTIL THE TRANSFER
DATE,  THE  APPLICABLE  CERTIFICATES  SHALL  BE  GOVERNED  BY AND  CONSTRUED  IN
ACCORDANCE WITH THE LAWS OF THE STATE OF DELAWARE.  THIS SECTION 8.02 SUPERSEDES
AND  REPLACES  SECTION  12.05  OF  THE  BASIC  AGREEMENT,  WITH  RESPECT  TO THE
APPLICABLE TRUST.

            SECTION 8.03.  EXECUTION IN COUNTERPARTS.  THIS TRUST SUPPLEMENT MAY
BE EXECUTED IN ANY NUMBER OF  COUNTERPARTS,  EACH OF WHICH SHALL BE AN ORIGINAL,
BUT SUCH COUNTERPARTS SHALL TOGETHER CONSTITUTE BUT ONE AND THE SAME INSTRUMENT.

            Section 8.04.  INTENTION OF PARTIES.  The parties hereto intend that
the  Applicable  Trust be classified  for U.S.  federal income tax purposes as a
grantor trust under  Subpart E, Part I of  Subchapter J of the Internal  Revenue
Code of  1986,  as  amended,  and not as a trust  or  association  taxable  as a
corporation or as a partnership. Each Applicable Certificateholder and Investor,
by its  acceptance  of  its  Applicable  Certificate  or a  beneficial  interest
therein,  agrees to treat the  Applicable  Trust as a grantor trust for all U.S.
federal, state and local income tax purposes. The powers granted and obligations

undertaken pursuant to the Agreement shall be so construed so as to further such
intent.

Agreement,  the "AGREEMENT"),  between the Trustee and the Company, a summary of
certain of the pertinent  provisions of which is set forth below.  To the extent
not  otherwise  defined  herein,  the  capitalized  terms used  herein  have the
meanings assigned to them in the Agreement.  This Certificate is one of the duly
authorized  Certificates designated as "8.048% Continental Airlines Pass Through
Certificates,  Series  2000-1A-1-O"  (herein  called the  "CERTIFICATES").  This
Certificate  is  issued  under  and is  subject  to the  terms,  provisions  and
conditions of the Agreement.  By virtue of its acceptance  hereof, the holder of
this Certificate (the  "CERTIFICATEHOLDER"  and, together with all other holders
of Certificates  issued by the Trust, the  "CERTIFICATEHOLDERS")  assents to and
agrees to be bound by the  provisions  of the  Agreement  and the  Intercreditor
Agreement.  The property of the Trust includes  certain  Equipment Notes and all
rights of the Trust to receive  payments under the  Intercreditor  Agreement and
the Liquidity Facility (the "TRUST PROPERTY"). Each issue of the Equipment Notes
is secured by, among other things, a security  interest in an Aircraft leased to
or owned by the Company.

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

            Subject to and in accordance with the terms of the Agreement and the
Intercreditor Agreement, from funds then available to the Trustee, there will be
distributed  on  each  May 1 and  November  1 (a  "REGULAR  DISTRIBUTION  Date")
commencing  May 1,  2000,  to the  Person  in whose  name  this  Certificate  is
registered  at the  close of  business  on the 15th day  preceding  the  Regular
Distribution  Date,  an amount  in  respect  of the  Scheduled  Payments  on the
Equipment Notes due on such Regular  Distribution Date, the receipt of which has
been confirmed by the Trustee,  equal to the product of the percentage  interest
in the Trust  evidenced  by this  Certificate  and an amount equal to the sum of
such  Scheduled  Payments.  Subject to and in  accordance  with the terms of the
Agreement and the Intercreditor Agreement, in the event that Special Payments on
the Equipment  Notes are received by the Trustee,  from funds then  available to
the Trustee,  there shall be distributed on the applicable Special  Distribution
Date, to the Person in whose name this Certificate is registered at the close of
business on the 15th day preceding the Special  Distribution  Date, an amount in
respect of such Special  Payments on the Equipment  Notes,  the receipt of which
has been  confirmed  by the  Trustee,  equal to the  product  of the  percentage
interest in the Trust  evidenced by this  Certificate and an amount equal to the
sum of such Special  Payments so  received.  If a Regular  Distribution  Date or
Special  Distribution Date is not a Business Day,  distribution shall be made on
the immediately following Business Day with the same force and effect as if made
on such Regular  Distribution Date or Special  Distribution Date and no interest
shall accrue  during the  intervening  period.  The Trustee shall mail notice of
each  Special  Payment  and  the  Special  Distribution  Date  therefor  to  the
Certificateholder of this Certificate.

            Distributions  on this  Certificate  will be made by the  Trustee by
check mailed to the Person entitled thereto,  without  presentation or surrender
of this  Certificate  or the making of any  notation  hereon,  except  that with
respect to Certificates  registered on the Record Date in the name of a Clearing
Agency  (or its  nominee),  such  distribution  shall be made by wire  transfer.
Except as otherwise provided in the Agreement and notwithstanding the above, the
final  distribution on this  Certificate will be made after notice mailed by the

<PAGE>

Trustee of the  pendency of such  distribution  and only upon  presentation  and
surrender of this  Certificate at the office or agency of the Trustee  specified
in such notice.

            The  Certificates  do not  represent a direct  obligation  of, or an
obligation  guaranteed  by, or an interest in, 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  Certificateholder  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,  privileges,  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
Company and the rights of the Certificateholders under the Agreement at any time
by the  Company  and the  Trustee  with the  consent  of the  Certificateholders
holding Certificates  evidencing  Fractional Undivided Interests aggregating not
less  than a  majority  in  interest  in the  Trust.  Any  such  consent  by the
Certificateholder  of this  Certificate  shall be conclusive and binding on such
Certificateholder and upon all future Certificateholders 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 set
forth therein,  the transfer of this  Certificate is registrable in the Register
upon surrender of this  Certificate for  registration of transfer at the offices
or agencies  maintained by the Trustee in its capacity as  Registrar,  or by any
successor  Registrar,  duly endorsed or accompanied  by a written  instrument of
transfer in form satisfactory to the Trustee and the Registrar, duly executed by
the  Certificateholder   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.

            Under certain  circumstances  set forth in Section 7.01 of the Trust
Supplement, all of the Trustee's right, title and interest to the Trust Property
may be assigned, transferred and delivered to the Related Trustee of the Related
Trust  pursuant  to  the  Assignment   and   Assumption   Agreement.   Upon  the
effectiveness of such Assignment and Assumption Agreement (the "Transfer"),  the
Trust shall be  terminated,  the  Certificateholders  shall  receive  beneficial

<PAGE>

interests  in the Related  Trust in exchange  for their  interests  in the Trust
equal to their  respective  beneficial  interests in the Trust, the Certificates
representing Fractional Undivided Interests in the Trust shall be deemed for all
purposes of the  Agreement  and the Related Pass Through  Trust  Agreement to be
certificates representing the same fractional undivided interests in the Related
Trust and its trust property. Each Certificateholder,  by its acceptance of this
Certificate  or a  beneficial  interest  herein,  agrees  to  be  bound  by  the
Assignment and Assumption Agreement and subject to the terms of the Related Pass
Through Trust Agreement as a  Certificateholder  thereunder.  From and after the
Transfer,  unless and to the extent the context otherwise  requires,  references
herein to the Trust, the Agreement and the Trustee shall  constitute  references
to the Related  Trust,  the Related Pass Through Trust  Agreement and trustee of
the Related Trust, respectively.

            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 issued in a
different  denomination.  As  provided in the  Agreement  and subject to certain
limitations  therein  set  forth,  the  Certificates  are  exchangeable  for new
Certificates   of  authorized   denominations   evidencing  the  same  aggregate
Fractional   Undivided   Interest   in   the   Trust,   as   requested   by  the
Certificateholder surrendering the same.

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

            Each  Certificateholder  and  Investor,  by its  acceptance  of this
Certificate  or a  beneficial  interest  herein,  agrees to treat the Trust as a
grantor trust for all U.S. federal, state and local income tax purposes.

            The  Trustee,  the  Registrar,  and any agent of the  Trustee or the
Registrar may treat the person in whose name this  Certificate  is registered as
the owner hereof for all purposes,  and neither 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.

            Any Person  acquiring or accepting  this  Certificate or an interest
herein will, by such  acquisition or acceptance,  be deemed to have  represented
and warranted to and for the benefit of each Owner  Participant  and the Company
that  either:  (i) the assets of an employee  benefit plan subject to Title I of
the Employee Retirement Income Security Act of 1974, as amended ("ERISA"), or of
a plan subject to Section 4975 of the Internal  Revenue Code of 1986, as amended
(the  "CODE"),  have not been used to purchase this  Certificate  or an interest
herein or (ii) the  purchase  and  holding of this  Certificate  or an  interest
herein are exempt from the prohibited transaction  restrictions of ERISA and the
Code pursuant to one or more prohibited  transaction statutory or administrative
exemptions.
