            (e) This Section 3.01 supersedes and replaces Section 4.03 of the

except as provided in Section 4.04 of the Basic Agreement. The Trustee shall
hold the Special Payments Account in trust for the benefit of the Applicable
Certificateholders and shall make or permit withdrawals therefrom only as
provided in the Agreement. On each day when one or more Special Payments are

receipt thereof, shall immediately deposit the aggregate amount of such Special
Payments in the Special Payments Account.

            (b) This Section 3.02 supersedes and replaces Section 4.01(b) of the

Section 7.01 of this Trust Supplement concerning the final distribution) by
check mailed to such Applicable Certificateholder, at the address appearing in
the Register, such Applicable Certificateholder's pro rata share (based on the
Fractional Undivided Interest in the Applicable Trust held by such Applicable
Certificateholder) of the total amount in the Special Payments Account on
account of such Special Payment, except that, with respect to Applicable
Certificates registered on the Record Date in the name of a Clearing Agency (or
its nominee), such distribution shall be made by wire transfer in immediately
available funds to the account designated by such Clearing Agency (or such
nominee).

            (b) The Trustee shall, at the expense of the Company, cause notice
of each Special Payment to be mailed to each Applicable Certificateholder at his
address as it appears in the Register. In the event of redemption or purchase of
Equipment Notes held in the Applicable Trust, such notice shall be mailed not
less than 15 days prior to the Special Distribution Date for the Special Payment
resulting from such redemption or purchase, which Special Distribution Date
shall be the date of such redemption or purchase. In the event of the payment of
a Deposit Make-Whole Premium by the Company to the Trustee under the NPA, such

<PAGE>

notice shall be mailed, together with the notice by the Escrow Paying Agent
under Section 2.07 of the Escrow Agreement, not less than 15 days prior to the
Special Distribution Date for such amount, which Special Distribution Date shall
be the date that the Depositary is obligated to pay the amount of the Partial
Withdrawal under the Deposit Agreement. 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, stating the
Special Distribution Date for such Special Payment which shall occur not less
than 15 days after the date of such notice and as soon as practicable
thereafter. Notices mailed by the Trustee shall set forth:

      (except as otherwise provided in Section 7.01 of this Trust Supplement),

            (ii) the amount of the Special Payment for each $1,000 face amount
      Applicable Certificate and the amount thereof constituting principal,
      premium, if any, and interest,

            (iii) the reason for the Special Payment, and

            (iv) if the Special Distribution Date is the same date as a Regular
      Distribution Date, the total amount to be received on such date for each
      $1,000 face amount Applicable Certificate.

If the amount of (i) premium, if any, payable upon the redemption or purchase of
an Equipment Note or (ii) the Deposit Make-Whole Premium, if any, 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 of the Equipment Notes held in the Trust is
canceled, the Trustee, as soon as possible after learning thereof, shall cause
notice thereof to be mailed to each Applicable Certificateholder at its address
as it appears on the Register.

            (b) This Section 3.03 supersedes and replaces Section 4.02(b) and
Section 4.02(c) of the Basic Agreement in their entirety, with respect to the
Applicable Trust.

            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

<PAGE>

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

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 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)

<PAGE>

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 the 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. (a) If the Company shall have
given the Partial Withdrawal Direction to the Trustee, the Trustee shall
instruct (as and when specified in the Partial Withdrawal Direction) the Escrow
Agent to provide a Notice of Partial Withdrawal to the Depositary substantially
in the form of Exhibit C to the Deposit Agreement requesting the withdrawal of a
portion of the Deposits (in the respective amounts and from the accounts as
shall be specified in the Partial Withdrawal Direction) and payment of accrued
interest thereon in accordance with and to the extent permitted by the terms of
the Escrow Agreement and the Deposit Agreement, all as shall be described in the
Partial Withdrawal Direction. On the date that the Depositary is obligated to
pay the amount of the Partial Withdrawal to the Escrow Paying Agent pursuant to
the Deposit Agreement, the Trustee will make a demand upon the Company under the
NPA for an amount equal to the Deposit Make-Whole Premium in respect of such
Partial Withdrawal.

            (b) 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").

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

      the effect set forth below and may be relied upon by the Beneficiaries (as
      defined in the Assignment and Assumption Agreement):

<PAGE>

                  (I) Upon the execution and delivery thereof by the parties
            thereto in accordance with the terms of the 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 the Agreement
            and the Related Pass Through Trust Agreement, each of the Applicable
            Certificates then Outstanding will be entitled to the benefits of
            the 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;

                  (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 the 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 the 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

<PAGE>

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.

            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.


                                  ARTICLE VIII
                            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

<PAGE>

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.

<PAGE>

            IN WITNESS WHEREOF, the Company and the Trustee have caused this
Trust Supplement to be duly executed by their respective officers thereto duly
authorized, as of the day and year first written above.

Continental Airlines, Inc., a Delaware corporation (the "COMPANY"), as
supplemented by Trust Supplement No. 2001-1B-O thereto, dated as of April 19,
2001 (the "TRUST SUPPLEMENT" and, together with the Basic 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 "7.373% Continental Airlines Pass Through
Certificates, Series 2001-1B-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 June 15 and December 15 (a "REGULAR DISTRIBUTION DATE")
commencing December 15, 2001, 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

<PAGE>

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
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.

<PAGE>

            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
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

<PAGE>

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.

            THE AGREEMENT AND, UNTIL THE TRANSFER, THIS CERTIFICATE SHALL BE
GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF DELAWARE
AND THE OBLIGATIONS, RIGHTS AND REMEDIES OF THE PARTIES HEREUNDER SHALL BE
