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 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 such
Trust Supplement and conclusive in favor of the Trustee, the Company and the
related Loan Trustee, if made in the manner provided in this Section.

or administer oaths that the Person executing such instrument acknowledged to

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

given any direction, consent or waiver (a "Direction"), under this Agreement,
Certificates owned by the Company, the Guarantor, 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 which 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
Company, the Guarantor, any related Owner Trustee, any related Owner
Participant or any Affiliate of any such Person.

     (d) The 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 Act.
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 30 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 Act

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
Act, 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 Act by the
Certificateholders on such record date shall be deemed effective unless it
shall become effective pursuant to the provisions of this Basic Agreement not
later than one year after the record date.

     (e) Any direction, consent, waiver or other action by the
Certificateholder of any Certificate shall bind the Certificateholder of every
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 1.04(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.

any Intercreditor Agreement, will have no rights, benefits or interests in
respect of any other Trust or the Trust Property held therein. All

     (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 form delivered
to the Trustee by the 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 such Equipment Notes and, concurrently
therewith, the Trustee shall purchase, pursuant to the terms and conditions of
the Note Purchase Agreements, the Equipment Notes at a purchase price equal to
the amount of such consideration so received. Except as provided in Sections
3.03, 3.04 and 3.05 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 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 invested by the
Trustee at the written direction and risk of, and for the benefit of, the
Company in Specified Investments (i) maturing no later than any scheduled
Transfer Date relating to such series of Certificates or (ii) if no such
Transfer Date has been scheduled, maturing on the next Business Day, or (iii)
if the Company has given notice to the Trustee that any Postponed Notes will
not be issued, with respect to the portion of the Escrowed Funds relating to
such Postponed Notes, maturing on the next applicable Special Distribution
Date, if such investments are reasonably available for purchase. The Trustee
shall

                                                                            15

make withdrawals from the Escrow Account only as provided in this Agreement.
Upon request of the 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 purchase price shall equal the principal amount of such Postponed
Notes.

     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 written direction and risk of, and for the benefit of, the
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 promptly distributed to the Company. The Company shall pay to
the Trustee for deposit to the relevant Escrow Account an amount equal to any
losses on such Specified Investments as incurred. On the Initial Regular
Distribution Date in respect of the Certificates of any series, the Company
will pay (in immediately available funds) to the Trustee an amount equal to
the interest that would have accrued on any Postponed Notes, if any, purchased
after the Issuance Date 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.

     If, in respect of the Certificates of any series, the Company notifies
the Trustee prior to the Cut-off Date that any Postponed Notes will not be
issued on or prior to the 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 (i) the 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
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 that
amount of Escrowed Funds that would have been used to purchase the Postponed
Notes designated in such notice and the amount paid by the 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 (i) the 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 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 such unused Escrowed Funds and the amount paid by
the 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.

     Section 2.03. 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 Equipment Notes to be acquired pursuant to Section 2.02
hereof and the related 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 2.04. Limitation of Powers. Each Trust shall be constituted
solely for the purpose of making the investment in the Equipment Notes
provided for in the related Trust Supplement, and, except as set forth herein
or 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 the Aircraft (as defined in the respective related Indentures) by
bidding such Equipment Notes or otherwise, or taking any action with respect
to any such Aircraft once acquired).

                                 ARTICLE III

                               THE CERTIFICATES

     Section 3.01. Form, Denomination and Execution of Certificates. The
Certificates of each series shall be issued in fully registered form 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 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 3.09, the definitive Certificates of such
series shall be 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 the 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 such 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

<PAGE>
                                                                            17

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 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 3.02. 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
Equipment Notes to be purchased by the Trustee pursuant to the related Note
Purchase Agreements, and evidencing the entire ownership of the related Trust.

     Section 3.03. Temporary Certificates. Pending the preparation of
definitive Certificates of any series, the Trustee may execute, authenticate
and deliver temporary Certificates of such series which 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 its execution of
such temporary Certificates.

     If temporary Certificates of any series are issued, the Company 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 3.04. 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.

<PAGE>
                                                                            18

     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 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.

     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 and exchange
shall be cancelled and subsequently destroyed by the Trustee.

     Section 3.05. 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 3.05, 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 3.05 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 3.06. Persons Deemed Owners. Prior to due presentation of a
Certificate for registration of transfer, the Trustee, the Registrar, and any
Paying Agent of the Trustee may treat the person in whose name any Certificate
is registered as the owner of such Certificate for the purpose of receiving
distributions pursuant to Section 4.02 and for all other purposes whatsoever,
and neither the Trustee, the Registrar, nor any Paying Agent of the Trustee
shall be affected by any notice to the contrary.

     Section 3.07. Cancellation. All Certificates surrendered for payment or
transfer or exchange shall, if surrendered to any Person party hereto 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 3.08. Limitation of Liability for Payments. All payments or
distributions made to Certificateholders of any series under 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 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.

     Section 3.09. 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 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 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 (the "Definitive Certificates") have been issued
pursuant to Subsection (d) below:

          (i) the provisions of this Section 3.09 shall be in full force and
     effect;

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

          (iii) to the extent that the provisions of this Section 3.09
     conflict with any other provisions of this Agreement (other than the
     provisions of any Trust Supplement amending this Section 3.09 as
     permitted by this Basic Agreement), the provisions of this Section 3.09
     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 distributions of principal and interest and premium, if any,
     on the Certificates to such Clearing Agency Participants; and

          (v) 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

<PAGE>
                                                                            20

     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.

     (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 on such Record Date.

     (d) If with respect to the Certificates of any series (i) the 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
Company is unable to locate a qualified successor, (ii) the Company at its
option, advises the Trustee in writing that it elects to terminate the
book-entry system through the Clearing Agency 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, by Act of said Certificate Owners
delivered to the Company and the Trustee, advise the 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
Participants 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 any 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 registration instructions from the Clearing Agency Participants
for registration of Definitive Certificates in the names of Certificate Owners
of such series, the Trustee shall issue and deliver the Definitive
Certificates of such series in accordance with the instructions of the
Clearing Agency. Neither the 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 issuance of Definitive Certificates of such series, the
Trustee shall recognize the Person in whose name the Definitive Certificates
are registered in the Register as Certificateholders hereunder. Neither the
Company nor the Trustee shall be liable if the Trustee or the 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 3.09 may be made inapplicable to any
series or may be amended with respect to any series in the related Trust
Supplement.

                              CERTIFICATEHOLDERS

     Section 4.01. Certificate Account and Special Payments Account.

     (a) The Trustee shall establish and maintain on behalf of the
Certificateholders of each series a Certificate Account as one or more
non-interest-bearing accounts. The Trustee shall hold the Certificate Account
in trust for the benefit of the Certificateholders of such series, and shall
make or permit withdrawals therefrom only as provided in this Agreement. On
each day when a Scheduled Payment is made to the Trustee, the Trustee, upon
receipt thereof, shall immediately deposit the aggregate amount of such
Scheduled Payment into the Certificate Account.

     (b) The Trustee shall establish and maintain on behalf of the
Certificateholders of each series a Special Payments Account as one or more
accounts, which shall be non-interest bearing except as provided in Section
4.04. The Trustee shall hold the Special Payments Account in trust for the
benefit of the Certificateholders of such series, and shall make or permit
withdrawals therefrom only as provided in this Agreement. On each day when one
or more Special Payments are made to the Trustee, the Trustee, upon receipt
thereof, shall immediately deposit the aggregate amount of such Special
Payments into the Special Payments Account.

     (c) The Trustee shall present to the Loan Trustee to which an Equipment
Note relates such Equipment Note on the date of its stated final maturity or,
in the case of any Equipment Note which is to be redeemed in whole pursuant to
the relevant Indenture, on the applicable redemption date under such
Indenture.

     Section 4.02. Distributions from Certificate Account and Special Payments
Account.

     (a) On each Regular Distribution Date with respect to a series of
Certificates or as soon thereafter as the Trustee has confirmed receipt of the
payment of the Scheduled Payments due on the Equipment Notes held in the
related Trust on such date, the Trustee shall distribute out of the applicable
Certificate Account the entire amount deposited therein pursuant to Section
4.01(a). There shall be so distributed to each Certificateholder of record of
such series on the Record Date with respect to such Regular Distribution Date
(other than as provided in Section 11.01 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 Certificate
Account.

     (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 the Special Payments due on the Equipment Notes held
in the related Trust or realized upon the sale

<PAGE>
                                                                            22

of such Equipment Note, the Trustee shall distribute out of the applicable
Special Payments Account the entire amount deposited therein pursuant to
Section 4.01(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 11.01
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 Company, cause notice of
each Special Payment with respect to a series of Certificates to be mailed to
each Certificateholder of such series at his address as it appears in the
Register. In the event of redemption or purchase of Equipment Notes held in
the related Trust, such notice shall be mailed not less than 20 days prior to
the date any such Special Payment is scheduled to 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 11.01),

          (ii) the amount of the Special Payment for each $1,000 face amount
     Certificate (taking into account any payment to be made by the Company
     pursuant to Section 2.02(b)) 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 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 an Equipment 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 of the Equipment 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.

     Section 4.03. Statements to Certificateholders.

     (a) On each Regular Distribution Date and Special Distribution Date with
respect to a series of Certificates, the Trustee will include with each
distribution to Certificateholders of the related series a statement, giving
effect to such distribution to be made on such Regular

<PAGE>
                                                                            23

Distribution Date or Special Distribution Date, as the case may be, setting
forth the following information (per a $1,000 face amount Certificate 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 of the related Trust.

          With respect to the Certificates registered in the name of a
Clearing Agency or its nominee, on the record date prior to each Distribution
Date, the Trustee will request from the Clearing Agency a securities position
listing setting forth the names of all the Clearing Agency Participants
reflected on the Clearing Agency's books as holding interests in the
Certificates on such record date. On each Distribution Date, the applicable
Trustee will mail to each such Clearing Agency Participant the statement
described above and will make available additional copies as requested by such
Clearing Agency Participant for forwarding to holders of Certificates.

     (b) Within a reasonable period of time after the end of each calendar
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

cost and expense, will do or cause to be done all things necessary to preserve
and keep in full force and effect its corporate existence, rights and
franchises, except as otherwise specifically permitted in Section 5.02;
provided, however, that the Company shall not be required to preserve any
right or franchise if the Company shall determine that the preservation
thereof is no longer desirable in the conduct of the business of the Company.

     Section 5.02. Consolidation, Merger, etc. The Company shall not
consolidate with or merge into any other corporation or convey, transfer or
lease substantially all of its assets as an entirety to any Person unless:

     (a) the corporation formed by such consolidation or into which the
Company is merged or the Person which acquires by conveyance, transfer or
lease substantially all of the assets of the Company as an entirety shall be a
"citizen of the United States" (as defined in Section 40102(a)(15) of Title 49
of the United States Code) holding a carrier operating certificate issued by
the Secretary of Transportation pursuant to Chapter 447 of Title 49, United
States Code, for aircraft capable of carrying 10 or more individuals or 6,000
pounds or more of cargo and with respect to which there is in force an air
carrier operating certificate issued pursuant to Part 121 of the regulations
under the sections of Title 49, United States Code, relating to aviation;

     (b) the corporation formed by such consolidation or into which the
Company is merged or the Person which acquires by conveyance, transfer or
lease substantially all of the assets of the Company as an entirety shall
execute and deliver to the Trustee applicable to the Certificates of each
series a duly authorized, valid, binding and enforceable agreement in form and
substance reasonably satisfactory to the Trustee containing an assumption by
such successor corporation or Person of the due and punctual performance and
observance of each covenant and condition of the Note Documents and of this
Agreement applicable to the Certificates of each series to be performed or
observed by the Company;

     (c) immediately after giving effect to such transaction, no Event of
Default applicable to the Certificates of each series or event which is, or
after notice or passage of time, or both, would be, such an Event of Default
shall have occurred and be continuing; and (d) the Company shall have
delivered to the Trustee an Officers' Certificate of the Company and an
Opinion of Counsel of the Company (which may be the Company's General Counsel)
reasonably satisfactory to the Trustee, each stating that such consolidation,
merger, conveyance, transfer or lease and the assumption agreement mentioned
in clause (b) above comply with this Section 5.02 and that all conditions
precedent herein provided for relating to such transaction have been complied
with.

     Upon any consolidation or merger, or any conveyance, transfer or lease of
substantially all of the assets of the Company as an entirety in accordance
with this Section 5.02, the successor

corporation or Person formed by such consolidation or into which the Company
is merged or to which such conveyance, transfer or lease is made shall succeed
to, and be substituted for, and may exercise every right and power of, the
Company under this Agreement applicable to the Certificates of each series
with the same effect as if such successor corporation or Person had been named
as the Company herein. No such conveyance, transfer or lease of substantially
all of the assets of the Company as an entirety shall have the effect of
releasing the Company or any successor corporation or Person which shall
theretofore have become such in the manner prescribed in this Section 5.02
from its liability in respect of any Note Document and of this Agreement
applicable to the Certificates of such series to which it is a party.

                                  ARTICLE VI

                                    DEFAULT

     Section 6.01. Events of Default. (a) Exercise of Remedies: Upon the
occurrence and during the continuation of any Indenture Default under any
Indenture, the Trustee may, to the extent it is the Controlling Party at such
time, direct the exercise of remedies.

     (b) Purchase Rights of Certificateholders: By acceptance of its
Certificate, each Certificateholder agrees that at any time after the
occurrence and during the continuation of a Triggering Event, each
Certificateholder of Certificates of a series will have certain rights, the
exercise of which will be specified in the applicable Trust Supplement, to
purchase the class of Certificates with immediate seniority to the
Certificates held by the purchasing Certificateholder. The purchase price with
respect to the Certificates of any series shall be equal to the Pool Balance
of the Certificates of such series, together 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 Certificateholders under this Agreement,
any Intercreditor Agreement or any other Note Document or on or in respect of
the Certificates of such series; provided, however, that no such purchase of
Certificates of such series shall be effective unless the purchaser shall
certify to the Trustee that contemporaneously with such purchase, such
purchaser is purchasing, pursuant to the terms of this Agreement and the other
Agreements, if any, relating to Certificates of a series that are subject to
the same Intercreditor Agreement (such other Agreements, the "Other
Agreements"), the Certificates of each such series that is senior to the
Certificates held by such purchaser. Each payment of the purchase price of the
Certificates of any series 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. Each Certificateholder of any series agrees by its acceptance of
Certificates of such series that it will, upon payment from any such
Certificateholders of Certificates with a lower seniority of the purchase
price specified herein, forthwith sell, assign, transfer and convey to the
purchaser thereof (without recourse, representation or warranty of any kind
except for its own acts), all of the right, title, interest and obligation of
such Certificateholder in this Agreement, any Intercreditor Agreement, the
Liquidity Facility, the Note Documents and all Certificates of such series
held by such 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 Certificateholder's obligations under this Agreement,
any Intercreditor Agreement, the Liquidity Facility and the

                                                                            26

Note Documents. The Certificates of such series will be deemed to be purchased
on the date payment of the purchase price is made notwithstanding the failure
of the Certificateholders to deliver any Certificates of such series and, upon
such a purchase, (i) the only rights of the Certificateholders will be to
deliver the Certificates to the purchaser and receive the purchase price for
such Certificates of such series and (ii) if the purchaser shall so request,
such Certificateholder will comply with all of the provisions of Section 3.04
hereof to enable new Certificates of such series 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 Certificates shall be borne by
the purchaser thereof.

     Section 6.02. Incidents of Sale of Equipment Notes. Upon any sale of all
or any part of the Equipment Notes made either under the power of sale given
under this Agreement or otherwise for the enforcement of this Agreement, the
following shall be applicable:

          (1) Certificateholders and Trustee May Purchase Equipment Notes. Any
     Certificateholder, the Trustee in its individual or any other capacity or
     any other Person may bid for and purchase any of the Equipment Notes, and
     upon compliance with the terms of sale, may hold, retain, possess and
     dispose of such Equipment Notes in their own absolute right without
     further accountability.

          (2) Receipt of Trustee Shall Discharge Purchaser. The receipt of the
     Trustee or of the officer making such sale shall be a sufficient
     discharge to any purchaser for his purchase money, and, after paying such
     purchase money and receiving such receipt, such purchaser or its personal
     representative or assigns shall not be obliged to see to the application
     of such purchase money, or be in any way answerable for any loss,
     misapplication or non-application thereof.

          (3) Application of Moneys Received upon Sale. Any moneys collected
     by the Trustee upon any sale made either under the power of sale given by
     this Agreement or otherwise for the enforcement of this Agreement shall
     be applied as provided in Section 4.02.

     Section 6.03. Judicial Proceedings Instituted by Trustee; Trustee May
Bring Suit. If there shall be a failure to make payment of the principal of,
premium, if any, or interest on any Equipment Note, or if there shall be any
failure to pay Rent (as defined in the relevant Lease) under any Lease when
due and payable, then the Trustee, in its own name, and as trustee of an
express trust, as holder of such Equipment Notes, to the extent permitted by
and in accordance with the terms of any Intercreditor Agreement and any Note
Documents, shall be 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 Equipment Notes or under such Lease and may prosecute
any such claim or proceeding to judgment or final decree with respect to the
whole amount of any such sums so due and unpaid.

     Section 6.04. Control by Certificateholders. Subject to Section 6.03 and
any Intercreditor Agreement, the Certificateholders holding Certificates of a
series evidencing Fractional Undivided Interests aggregating not less than a
majority in interest in the related Trust shall have the right to direct the
time, method and place of conducting any proceeding for any

<PAGE>
                                                                            27

remedy available to the Trustee with respect to such Trust or pursuant to the
terms of any Intercreditor Agreement, or exercising any trust or power
conferred on the Trustee under this Agreement or any Intercreditor Agreement,
including any right of the Trustee as Controlling Party under any
Intercreditor Agreement or as holder of the Equipment Notes, provided that

          (1) such Direction shall not in the opinion of the Trustee be in
     conflict with any rule of law or with this Agreement 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, and

          (3) the Trustee may take any other action deemed proper by the
     Trustee which is not inconsistent with such Direction.

     Section 6.05. Waiver of Past Defaults. Subject to any Intercreditor
Agreement, the Certificateholders holding Certificates of a series evidencing
Fractional Undivided Interests aggregating not less than a majority in
interest in the Trust (i) may on behalf of all of the Certificateholders waive
any past Event of Default hereunder and its consequences or (ii) if the
Trustee is the Controlling Party, may direct the Trustee to instruct the
applicable Loan Trustee to waive, any past Indenture Default under any
Indenture and its consequences, and thereby annul any Direction given by such
Certificateholders or the Trustee to such Loan Trustee with respect thereto,
except a default:

          (1) in the deposit of any Scheduled Payment or Special Payment under
     Section 4.01 or in the distribution of any payment under Section 4.02 on
     the Certificates of a series, or

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

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

          Upon any such waiver, such default shall cease to exist with respect
to Certificates of such series and any Event of Default arising therefrom
shall be deemed to have been cured for every purpose 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 Equipment Notes issued under the relevant Indenture to waive the
corresponding Indenture Default.

Section 6.06. Right of Certificateholders to Receive Payments Not To Be
Impaired. Anything in this Agreement to the contrary notwithstanding,
including without limitation

<PAGE>
                                                                            28

Section 6.07 hereof, but subject to any Intercreditor Agreement, the right of
any Certificateholder to receive distributions of payments required pursuant
to Section 4.02 hereof on the applicable Certificates when due, or to
institute suit for the enforcement of any such payment on or after the
applicable Regular Distribution Date or Special Distribution Date, shall not
be impaired or affected without the consent of such Certificateholder.

     Section 6.07. Certificateholders May Not Bring Suit Except Under Certain
Conditions. A Certificateholder of any series shall not have the right to
institute any suit, action or proceeding at law or in equity or otherwise 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 have requested the Trustee in writing to
     institute such action, suit or proceeding and shall have offered to the
     Trustee indemnity as provided in Section 7.02(e);

          (3) the Trustee shall have refused or neglected to institute any
     such action, suit or proceeding for 60 days after receipt of such notice,
     request and offer of indemnity; and

          (4) no direction inconsistent with such written request has been
     given 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.

     It is understood and intended that no one or more of the
Certificateholders of any series shall have any right in any manner whatever
hereunder or under the related Trust Supplement or under the Certificates of
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 Equipment
Notes, (ii) obtain or seek to obtain priority over or preference to any other
such Certificateholder of such series or (iii) enforce any right under this
Agreement, except in the manner herein provided and for the equal, ratable and
common benefit of all the Certificateholders of such series subject to the
provisions of this Agreement.

     Section 6.08. Remedies Cumulative. Every remedy given hereunder to the
Trustee or to any of the Certificateholders of any series shall not be
exclusive of any other remedy or remedies, and every such remedy shall be
cumulative and in addition to every other remedy given hereunder or now or
hereafter given by statute, law, equity or otherwise.

     Section 6.09. Undertaking for Costs. In any suit for the enforcement of
any right or remedy under this Agreement, or in any suit against the Trustee
for any action taken, suffered or omitted by it as Trustee, a court may
require any party litigant in such suit to file an undertaking to pay the
costs of such suit, and may assess costs against any such party litigant, in
the manner

                                                                            29

and to the extent provided in the Trust Indenture Act; provided
that neither this Section nor the Trust Indenture Act shall be deemed to
authorize any court to require such an undertaking or to make such an
assessment in any suit instituted by the Company or the Guarantor.

                                  ARTICLE VII

accordance with Section 313(c) of the Trust Indenture Act, notice of such
default hereunder known to the Trustee, unless such default shall have been
cured or waived; provided, however, that, except in the case of a default in
the payment of the principal of (premium, if any) or interest on any Equipment
Note, the Trustee shall be protected in withholding such notice if and so long
as the board of directors, the executive committee or a trust committee of
directors and/or Responsible Officers of the Trustee in good faith determine
that the withholding of such notice is in the interests of the
Certificateholders of the related series. For the purpose of this Section in
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 that Trust.

absence of bad faith on its part, rely upon an Officers' Certificate of the
Company, any related Owner Trustee or any related Loan Trustee;

     (d) the Trustee may consult with counsel and the advice of such counsel
or any Opinion of Counsel shall be full and complete authorization and
protection in respect of any action taken, suffered or omitted by it hereunder
in good faith and in reliance thereon;

rights or powers vested in it by this Agreement or any Intercreditor Agreement

omitted to be taken by it in good faith in accordance with the direction of
the Certificateholders holding Certificates of any series evidencing
Fractional Undivided Interests aggregating not less than a majority in
interest in the related Trust relating to the time, method and place of
conducting any proceeding for any remedy available to the Trustee, or
exercising any trust or power conferred upon the Trustee, under this Agreement
or any Intercreditor Agreement; and

     (i) the Trustee shall not be required to expend or risk its own funds in
the performance of any of its duties under this Agreement, or in the exercise
of any of its rights or powers, if it shall have reasonable grounds for
believing that repayment of such funds or adequate indemnity 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 be
read into this Agreement or be enforceable against Trustee.

     Section 7.05. Money Held in Trust. Money held by the Trustee or the
Paying Agent in trust hereunder or under any Trust Supplement need not be
segregated from other funds except to the extent required herein or by law and
neither the Trustee nor the Paying Agent shall have any liability for interest
upon any such moneys except as provided for herein.

     Section 7.06. Compensation and Reimbursement. The Company agrees:

          (1) to pay, or cause to be paid, to the Trustee from time to time

     Supplement, to reimburse, or cause to be reimbursed, the Trustee upon its

     advances incurred or made by the Trustee in accordance with any provision
     of this Basic Agreement, any Trust Supplement or any Intercreditor
     Agreement (including the reasonable compensation and the expenses and
     disbursements of its agents and counsel), except any such expense,

     misconduct or bad faith or as may be incurred due to the Trustee's breach
     of its representations and warranties set forth in Section 7.14;

          (3) to indemnify, or cause to be indemnified, the Trustee for, and
     to hold it harmless against, any loss, liability or expense (other than
     for or with respect to any tax) incurred without negligence, willful
     misconduct or bad faith, on its part, arising out of or in connection
     with the acceptance or administration of this Trust, including the costs
     and expenses of defending itself against any claim or liability in
     connection with the exercise or performance of any of its powers or
     duties hereunder, except for any such loss, liability or expense incurred
     by reason of the Trustee's breach of its representations and warranties
     set forth in Section 7.14. The Trustee shall notify the Company and the
     Guarantor promptly of any claim for which it may seek indemnity. The
     Company and the Guarantor shall defend the claim and the Trustee shall
     cooperate in the defense. The Trustee may have separate counsel with the
     consent of the Company and the Guarantor and the Company and the

     administration of this Trust, including any costs and expenses incurred
     in contesting the imposition of any such tax. The Trustee, in its

     shall permit the Company and the Guarantor to contest the imposition of
     such tax

<PAGE>
                                                                            32

     and the Trustee, in its individual capacity, shall cooperate in the
     defense. The Trustee, in its individual capacity, may have separate
     counsel with the consent of the Company and the Guarantor and the Company
     and the Guarantor will pay the reasonable fees and expenses of such
     counsel. Neither the Company nor the Guarantor need pay for any taxes
     paid, in settlement or otherwise, without its consent.

     The Trustee shall be entitled to reimbursement from, and shall have a
lien prior to the Certificates of each series upon, all property and funds
held or collected by the Trustee in its capacity as Trustee with respect to
such series or the related Trust for any tax incurred without negligence, bad
faith or willful misconduct, on its part, arising out of or in connection with
the acceptance or administration of such Trust (other than any tax
attributable to the Trustee's compensation for serving as such), including any
costs and expenses incurred in contesting the imposition of any such tax. The
Trustee shall notify the Company of any claim for any tax for which it may
seek reimbursement. The Trustee shall cooperate in the contest by the Company
of any such claim. If the Trustee reimburses itself from the Trust Property of
such Trust for any such tax it will within 30 days mail a brief report setting
forth the amount of such tax and the circumstances thereof to all
Certificateholders of such series as their names and addresses appear in the
Register.

     As security for the performance of the obligations of the Company under
this Section with respect to each Trust the Trustee shall have a lien prior to
the Certificates of the related series upon all property and funds held or
collected by the Trustee in its capacity as Trustee with respect to such
Certificates and the related Trust.

     Section 7.07. Corporate Trustee Required; Eligibility. Each Trust shall
at all times have a Trustee which shall be eligible to act as a trustee under
Section 310(a) of the Trust Indenture Act and shall have a combined capital
and surplus of at least $75,000,000 (or a combined capital and surplus in
excess of $5,000,000 and the obligations of which, whether now in existence or
hereafter incurred, are fully and unconditionally guaranteed by a corporation
organized and doing business under the laws of the United States, any State or
Territory thereof or of the District of Columbia that has a combined capital
and surplus of at least $75,000,000). If such corporation publishes reports of
conditions at least annually, pursuant to law or to the requirements of
Federal, State, Territorial or District of Columbia supervising or examining
authority, then for the purposes of this Section 7.07, the combined capital
and surplus of such corporation shall be deemed to be its combined capital and
surplus as set forth in its most recent report of conditions so published.

     In case at any time the Trustee shall cease to be eligible in accordance
with the provisions of this Section 7.07 to act as Trustee of any Trust, the
Trustee shall resign immediately as Trustee of such Trust in the manner and
with the effect specified in Section 7.08.

     Section 7.08. Resignation and Removal; Appointment of Successor.

     (a) 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
7.09.

<PAGE>
                                                                            33

     (b) The Trustee may resign at any time as trustee of any or all Trusts by
giving written notice thereof to the Company, the Authorized Agents, the
related Owner Trustees and the related Loan Trustees. If an instrument of
acceptance by a successor Trustee shall not have been delivered to the
Company, the related Owner Trustees and the Trustee within 30 days after the
giving of such notice of resignation, 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
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 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 7.07 and
     shall fail to resign after written request therefor by the 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;

then, in any case, (i) the Company may remove the Trustee 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 which has
been or is likely to be asserted, the Trustee shall promptly notify the
Company and shall, within 30 days of such notification, resign as Trustee of
such Trust hereunder unless within such 30-day period the Trustee shall have
received notice that the Company has agreed to pay such tax. The 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 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

<PAGE>
                                                                            34

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 Company, the related Owner
Trustees, the related Loan Trustee and the retiring Trustee, the successor
Trustees so appointed shall, with the approval of the Company, which approval
shall not be unreasonably withheld, 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, the resigning Trustee or 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.

     Section 7.09. Acceptance of Appointment by Successor. Every successor
Trustee appointed hereunder shall execute, acknowledge and deliver to the
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 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 7.06. Upon request of any such successor Trustee, the
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 Company, the predecessor Trustee and each successor Trustee
with respect to any Trust shall execute and deliver a supplemental agreement
hereto which 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 constitute such

<PAGE>
                                                                            35

Trustees 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 to such
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, 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 the related Trust Supplement may be served. Such office or agency shall be
initially at 61 Broadway, New York, New York 10006. 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 Company, the Guarantor, 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 having a
combined capital and surplus in excess of $5,000,000 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 3.04, Registrar hereunder with respect to the Certificates of each
series. Each Registrar shall furnish to the Trustee, at stated intervals of
not more than six months, and at such other times as the Trustee may request
in writing, a copy of the Register maintained by such Registrar.

                                                                            36

     (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 Company, any related Owner Trustees and the
related Loan Trustees. The 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 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 Company shall promptly
appoint one or more qualified successor Authorized Agents, reasonably
satisfactory to the Trustee, to perform the functions of the Authorized Agent
which has resigned or whose agency has been terminated or who shall have
ceased to be eligible under this Section. The 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 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 Equipment Notes in Trustee's Name. Subject
to the provisions of any Intercreditor Agreement, the Trustee agrees that all
Equipment Notes, and Permitted Investments, if any, shall be issued in the

held by the Trustee, or, if not so held, the Trustee or its

<PAGE>
                                                                            37

Investments as the case may be, in the register of the issuer of such
Equipment Notes or Permitted Investments.

     any mortgage, indenture, contract, agreement or other undertaking to
     which it is a party, which violation, default or lien could reasonably be

     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.

Certificates of any series, the Trustee, as trustee of the related grantor

     provisions of this Agreement cannot be modified or waived without the
     consent of the Certificateholder of each Certificate or such series
     affected thereby.

     It shall not be necessary for any Act of such Certificateholders under
this Section to approve the particular form of any proposed supplemental

affects any interest, right, duty, immunity or indemnity in favor of the

its discretion decline to execute such document.

     Section 9.04. Execution of Supplemental Agreements. In executing, or

permitted by this Article or the modifications thereby of the trusts created

Agreement.

     Section 9.05. Effect of Supplemental Agreements. Upon the execution of

                                  ARTICLE X

                  AMENDMENTS TO INDENTURE AND NOTE DOCUMENTS

     Section 10.01. Amendments and Supplements to Indenture and Other Note
Documents. In the event that the Trustee, as holder of any Equipment Notes in
trust for the benefit of the Certificateholders of any series or as
Controlling Party, receives a request for a consent to any amendment,
modification, waiver or supplement under any Indenture or other Note Document
the Trustee shall forthwith send a notice of such proposed amendment,
modification, waiver or supplement to each Certificateholder of such series
registered on the Register as of the date of such notice. The Trustee shall
request from Certificateholders of such series a Direction as to (a) whether
or not to take or refrain from taking any action which a holder of such
Equipment Note has the option to direct, (b) whether or not to give or execute
any waivers, consents, amendments, modifications or supplements as a holder of
such Equipment Note and (c) how to vote any Equipment Note if a vote has been
called for with respect thereto. Provided such a request for Certificateholder
Direction shall have been made, in directing any action or casting any vote or
giving any consent as the holder of any Equipment Note, the Trustee shall vote
for or give consent to any such action with respect to such Equipment Note in
the same proportion as that of (i) the aggregate face amounts of all
Certificates of such series actually voted in favor of

<PAGE>
                                                                            43

or for giving consent to such action by Acts of Certificateholders to (ii) the
aggregate face amount of all Outstanding Certificates. For purposes of the
immediately preceding sentence, a Certificate shall have been "actually voted"
if the Holder of such Certificate has delivered to the Trustee an instrument
evidencing such Holder's consent to such Direction on or prior to the Business
Day before the Trustee directs such action or casts such vote or gives such
consent. Notwithstanding the foregoing, but subject to Section 6.04 and any
Intercreditor Agreement, the Trustee may, in its own discretion and at its own
direction consent and notify the relevant Loan Trustee of such consent to any
amendment, modification, waiver or supplement under the relevant Indenture,
Liquidity Facility, or any Note Document, if an Event of Default hereunder
shall have occurred and be continuing, or if such amendment, modification or
waiver will not adversely affect the interests of the Certificateholders.

                                  ARTICLE XI

                             TERMINATION OF TRUSTS

     Section 11.01. Termination of the Trusts. In respect of each Trust
created by the Basic Agreement as supplemented by a related Trust Supplement,
the respective obligations and responsibilities of the Company, the Guarantor
and the Trustee created under this Agreement and the Trust created hereby and
such Trust shall 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 pursuant to this Agreement and the
disposition of all property held as part of the Trust Property of the related
series of such Trust; provided, however, that in no event shall such Trust
continue beyond the final expiration date determined as provided in this
Agreement.

     Notice of any termination of a Trust, specifying the applicable Regular
Distribution Date (or applicable Special Distribution Date, as the case may
be) upon which the Certificateholders of any series 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 specifying (A) the Regular Distribution Date
(or Special Distribution Date, as the case may be) upon which the proposed
final payment of the Certificates of such series will be made upon
presentation and surrender of Certificates of such series 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
Regular Distribution Date (or Special Distribution Date, as the case may be)
is not applicable, payments being made only upon presentation and surrender of
the Certificates of such series 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 Certificateholders of such series. Upon presentation
and surrender of the 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 4.02.

     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

<PAGE>
                                                                            44

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 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 and the Company.

                                 ARTICLE XII

                           MISCELLANEOUS PROVISIONS

     Section 12.01. Limitation on Rights of Certificateholders. The death or
incapacity of any Certificateholder of any series shall not operate to
terminate this Agreement, or the related Trust, nor entitle such
Certificateholder's legal representatives or heirs to claim an accounting or
to take any action or commence any proceeding in any court for a partition or
winding up of the Trust, nor otherwise affect the rights, obligations, and
liabilities of the parties hereto or any of them.

     Section 12.02. Liabilities of Certificateholders. Neither the existence
of the Trust nor any provision in this Agreement is intended to or shall limit
the liability the Certificateholders would otherwise incur if the

obligations of the Trust, directly rather than through the Trust.

     Section 12.03. Certificates Nonassessable and Fully Paid.
Certificateholders of each series shall not be personally liable for

losses or expenses of such Trust or for any reason whatsoever, and
Certificates of such series upon authentication thereof by the Trustee
pursuant to Section 3.02 are and shall be deemed fully paid. No
Certificateholder of such series shall have any right (except as expressly
provided herein) to vote or in any manner otherwise control the operation and
management of the related Trust Property, the related Trust, or the
obligations of the parties hereto, nor shall anything set forth herein, or
contained in the terms of the Certificates of such series, be construed so as
to constitute the Certificateholders of such series from time to time as
partners or members of an association.

     Section 12.04. Registration of Equipment Notes in Name of Subordination
Agent. If a Trust is party to an Intercreditor Agreement, the Trustee agrees
that all Equipment Notes to be purchased by such Trust shall be issued in the

nominee and held by such Subordination Agent in trust for the benefit of the

Agreement for any other series of certificates issued pursuant thereto. [The
undivided percentage interest in the Trust represented by each of this

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,

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

Certificate. The Agreement also permits the amendment thereof, in certain
limited circumstances, without the consent of the Certificateholders of any of

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.

     The Certificates are issuable only as registered Certificates without
coupons in minimum denominations of $1,000 Fractional Undivided Interest and

     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.

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

Property.

Non-Issuance Withdrawal to the Depositary requesting (i) the withdrawal of
principal amounts from one or more Deposit Accounts in the amounts and on the
date specified in such Class D Notice (together with accrued interest to such

extent permitted by the terms of the Escrow Agreement and the Deposit
Agreement and (ii) the payment to the Paying Agent (for payment to the
Receiptholders in accordance with the Escrow Agreement) of the amounts so
withdrawn from such Deposit Account or Accounts. If at any time prior to the
Applicable Delivery Date the Trustee receives a notice of postponement
pursuant to Section 2(e) or 2(f) of the Note Purchase Agreement, then the
Trustee shall give the Depositary (with a copy to the Escrow Agent) a notice
of cancellation of such Notice of Series D Non-Issuance Withdrawal relating to
such Deposit Account or Accounts. Amounts withdrawn from such Deposit Account
or Accounts, to the extent not distributed to the Receiptholders on the date

Corporation, a Delaware corporation (the "Guarantor"), and Northwest Airlines,
Inc., a Minnesota corporation (the "Company"), as supplemented by Trust
Supplement No. 2002-1G-1 thereto, dated as of ______ __, 2002 (collectively,
the "Agreement"), by and among the Trustee, the Guarantor 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 "Pass Through Certificates,
Series 2002-1G-1" (herein called the "Certificates"). This Certificate is
issued under and is subject to the terms, provisions and conditions of the
Agreement and the Intercreditor Agreement, to which Agreement the
Certificateholder of this Certificate by virtue of the acceptance hereof
assents and by which such Certificateholder is bound. The property of the
Trust includes certain Equipment Notes and all rights of the Trust to receive
payments under the Intercreditor Agreement, the Primary Liquidity Facility,
the Above-Cap Liquidity Facility and the Policy (the "Trust Property"). Each
issue of the Equipment Notes is secured by a security interest in the related
Aircraft.

          Each of the Certificates represents a Fractional Undivided Interest
in the Trust and the Trust Property and has 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 February 20, May 20, August 20 and November 20 (a
"Regular Distribution Date"), commencing on August 20, 2002 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 and interest shall accrue during the intervening
period. The Trustee shall mail notice of each Special Payment and the Special
Distribution Date therefor to the Certificateholder of this Certificate.

          Distributions on this Certificate will be made by the Trustee by
check mailed to the Person entitled thereto, without the presentation or
surrender of this Certificate or the making of any notation hereon, except
that with respect to Certificates registered on the Record Date in the name of
DTC (or its nominees), 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

                                                                             3

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

          The Certificates do not represent an obligation of, or an obligation
guaranteed by, or an interest in, the Guarantor, the Company or the Trustee or
any affiliate thereof. The Certificates are limited in right or payment, all
as more specifically set forth herein 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, 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 or the Company and the rights of the Certificateholders under the
Agreement at any time by the Guarantor, 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, 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.

          The Certificates are issuable only as registered Certificates
without coupons in minimum denominations of $1,000 Fractional Undivided
Interests and integral multiples thereof. 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.

          So long as any of the Certificates are listed on the Luxembourg
Stock Exchange and the rules of that stock exchange so require, notices to the
Certificateholders shall be given by publication in a daily newspaper having
general circulation in Luxembourg (which is expected to be the Luxemburger
Wort).

          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 or beneficial owner of a Certificate, 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.

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

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

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