     If any Responsible Officer of the Pass Through Trustee who signs any of
the Pass Through Certificates subsequently ceases to be such officer or
authorized agent before the Pass Through Certificate so signed is authenticated
and delivered or disposed of by the Pass Through Trustee, such Pass Through
Certificate nevertheless may be authenticated and delivered or disposed of as
though the person who signed such Pass Through Certificate had not ceased to be
such officer or authorized agent of the Pass Through Trustee; and any Pass
Through Certificate may be signed on behalf of the Pass Through Trustee by such
person or persons as, at the actual date of the execution of such Pass Through
Certificate, are the proper officers or authorized agents of the Pass Through
Trustee, although at the date of the execution and delivery of the related
Series Supplement any such person was not such officer.

     Section 2.06. Certificate of Authentication. The Pass Through Trustee
shall duly authenticate and deliver Pass Through Certificates for each Series
in authorized denominations equaling the aggregate principal amount of the
Equipment Certificates to be purchased for the related Pass Through Trust by
the Pass Through Trustee pursuant to the related Participation Agreements, and
evidencing the entire ownership of the related Pass Through Trust. Only such
Pass Through Certificates of such Series as shall bear thereon a certificate of
authentication substantially in the form set forth in Exhibit A, executed by
the Pass Through Trustee by manual or facsimile signature of a Responsible
Officer, shall be entitled to the benefits of the related Pass Through Trust or
be valid or

                                       18

<PAGE>

obligatory for any purpose. Such certificate of authentication by the Pass
Through Trustee upon any Pass Through Certificate for such Series executed by
the Pass Through Trustee shall be conclusive evidence that the Pass Through
Certificate so authenticated has been duly authenticated and delivered
hereunder and that the Certificateholder, as evidenced on the Register for such
Series, is entitled to the benefits of the related Pass Through Trust.

     Section 2.07. Form and Denomination of Pass Through Certificates. The
Pass Through Certificates of each Series shall be substantially in the form set
forth in Exhibit A hereto. The Pass Through Certificates shall be issuable as
registered securities without coupons and shall be numbered, lettered, or
otherwise distinguished in such manner or in accordance with such plans as set
forth in the related Series Supplement. The Pass Through Certificates of each
Series shall be issued in minimum denominations of $1,000 and integral
multiples thereof and shall be dated the date of their authentication.

     The Pass Through Certificates of any Series may be issued with appropriate
insertions, omissions, substitutions and variations, and may have imprinted or
otherwise reproduced thereon such legend, not inconsistent with the provisions
of this Pass Through Agreement or the related Series Supplement, as may be
required to comply with any law or with any rules or regulations pursuant
thereto, or with the rules of the Depository or any securities market in which
such Pass Through Certificates are admitted to trading, or to conform to
general usage.

     Section 2.08. Registration, Transfer and Exchange. The Pass Through
Trustee will keep at each office or agency to be maintained for any Series for
the purpose as provided in Section 3.02 hereof a Register in which, subject to
such reasonable regulations as it may prescribe, it will register, and will
register the transfer of, Pass Through Certificates of the related Series as
provided in this Article II. Such Register shall be in written form in the
English language.

     Upon due presentation for registration of transfer of any Pass Through
Certificate of the related Series at any such office or agency, the Pass
Through Trustee shall execute, authenticate and deliver in the name of the
transferee or transferees a new Pass Through Certificate of such Series in
authorized denominations and for a like aggregate Fractional Undivided
Interest.

     Subject to the provisions of Section 2.12 hereof, any Pass Through
Certificate or Pass Through Certificates may be exchanged for a Pass Through
Certificate or Pass Through Certificates of the same Series in other authorized
denominations and for a like aggregate Fractional Undivided Interest. Pass
Through Certificates to be exchanged shall be surrendered at any office or
agency to be maintained by the Pass Through Trustee for the related Series for
the

                                       19

<PAGE>

purpose as provided in Section 3.02 hereof, and the Pass Through Trustee shall
execute, authenticate and deliver in exchange therefor the Pass Through
Certificate or Pass Through Certificates which the Certificateholder making the
exchange shall be entitled to receive, bearing numbers not contemporaneously or
previously outstanding.

     All Pass Through Certificates presented for registration of transfer,
exchange, redemption or payment shall (if so required by the Pass Through
Trustee) be duly endorsed by, or be accompanied by a written instrument or
instruments of transfer in form satisfactory to the Pass Through Trustee duly
executed by, the Certificateholder or such Person's attorney duly authorized in
writing.

     The Pass Through Trustee may require payment from the Certificateholder of
a sum sufficient to cover any tax or other governmental charge that may be
imposed in connection with any exchange or registration of transfer of Pass
Through Certificates. No service charge to the Certificateholder shall be made
for any such transaction.

     All Pass Through Certificates issued upon any transfer or exchange of Pass
Through Certificates shall evidence ownership in the same Pass Through Trust
and be entitled to the same benefits under this Pass Through Agreement and the
applicable Series Supplement, as the Pass Through Certificates surrendered upon
such transfer or exchange.

     Resales or other transfers of Pass Through Certificates represented by a
Registered Global Certificate will be conducted in accordance with the
provisions of this Pass Through Agreement, including without limitation Section
6.06 hereof, and the rules and procedures of the Depository applicable to U.S.
corporate pass through certificates and without notice to, or action by, the
Pass Through Trustee.

     Neither the Company nor the Pass Through Trustee will have any
responsibility or liability for any aspect of the records relating to, or
payments made on account of, beneficial ownership interests of a Registered
Global Certificate or for maintaining, supervising or reviewing any records
relating to such beneficial interests.

     Section 2.09. Mutilated, Defaced, Destroyed, Lost and Stolen Pass Through
Certificates. If any Pass Through Certificate becomes mutilated, defaced or is
apparently destroyed, lost or stolen, the Pass Through Trustee in its
discretion may execute, authenticate and deliver a new Pass Through Certificate
of like Fractional Undivided Interest in the related Pass Through Trust,
bearing a number not contemporaneously or previously outstanding, in exchange
and

                                       20

<PAGE>

substitution for the mutilated or defaced Pass Through Certificate, or in lieu
of and in substitution for the Pass Through Certificate so apparently
destroyed, lost or stolen. In every case the applicant for a substitute Pass
Through Certificate shall furnish to the Pass Through Trustee and any agent of
the Pass Through Trustee such security or indemnity as may be required by them
to indemnify and defend and to save each of them harmless from any such
substitution and, in every case of destruction, loss or theft, evidence to
their satisfaction of the apparent destruction, loss or theft of such Pass
Through Certificate and of the ownership thereof.

     Upon the issuance of any substitute Pass Through Certificate, the Pass
Through Trustee may require payment from the Certificateholder of a sum
sufficient to cover any tax or other governmental charge that may be imposed in
relation thereto and any other reasonable expenses (including the reasonable
fees and expenses of the Pass Through Trustee) connected therewith. If any Pass
Through Certificate of a Pass Through Trust for which a notice of termination
has been or is about to be given pursuant to Section 12.01 hereof becomes
mutilated or defaced or is apparently destroyed, lost or stolen, the Pass
Through Trustee may, instead of issuing a substitute Pass Through Certificate,
pay or authorize the payment of the same (without surrender thereof except in
the case of a mutilated or defaced Pass Through Certificate), if the applicant
for such payment furnishes to the Pass Through Trustee and any agent of the
Pass Through Trustee such security or indemnity as any of them may require to
save each of them harmless from all risks, however remote, resulting from such
payment and, in every case of apparent destruction, loss or theft, the
applicant shall also furnish to the Pass Through Trustee and any agent of the
Pass Through Trustee evidence to their satisfaction of the apparent
destruction, loss or theft of such Pass Through Certificate and of the
ownership thereof.

     Every substitute Pass Through Certificate issued pursuant to the
provisions of this Section 2.09 by virtue of the fact that any Pass Through
Certificate is apparently destroyed, lost or stolen will constitute conclusive
evidence of the Fractional Undivided Interest in the applicable Pass Through
Trust evidenced by the Pass Through Certificate that it replaces, whether or
not the apparently destroyed, lost or stolen Pass Through Certificate may be
enforceable at any time by anyone and will be entitled to all the benefits of
(but will be subject to all the limitations of rights set forth in) the
applicable Pass Through Trust equally and proportionately with any and all
other Pass Through Certificates duly authenticated and delivered therefor. All
Pass Through Certificates will be held and owned upon the express condition
that, to the extent permitted by law, the foregoing provisions are exclusive
with respect to the replacement or payment of mutilated, defaced, or apparently
destroyed, lost or stolen Pass Through Certificates and will preclude any and
all other rights or remedies notwithstanding

                                       21

<PAGE>

any law or statute existing or hereafter enacted to the contrary with respect
to the replacement or payment of negotiable instruments or other securities
without their surrender.

     Section 2.10. Cancellation of Pass Through Certificates; Destruction
Thereof. All Pass Through Certificates surrendered for payment, redemption,
registration of transfer or exchange, if surrendered to any agent of the Pass
Through Trustee, shall be delivered to the Pass Through Trustee for
cancellation or, if surrendered to the Pass Through Trustee, shall be cancelled
by it; and no Pass Through Certificates shall be issued in lieu thereof except
as expressly permitted by any of the provisions of this Pass Through Agreement
or the applicable Series Supplement. The Pass Through Trustee shall destroy
cancelled Pass Through Certificates held by it.

     Section 2.11. Temporary Pass Through Certificates. Pending the preparation
of definitive Pass Through Certificates of any Series, the Pass Through Trustee
may execute, authenticate and deliver temporary Pass Through Certificates for
such Series (produced in a form satisfactory to the executing officer or
authorized agent of the Pass Through Trustee, as evidenced by such officer's or
authorized agent's execution thereof). Such temporary Pass Through Certificates
shall be issuable as registered Pass Through Certificates without coupons, of
any authorized denomination, and substantially in the form of the definitive
Pass Through Certificates of such Series but with such omissions, insertions
and variations as may be appropriate for temporary Pass Through Certificates,
all as may be determined by the executing officer of the Pass Through Trustee,
as evidenced by such officer's or authorized agent's execution thereof.

     Temporary Pass Through Certificates may contain such reference to any
provisions of this Pass Through Agreement or the applicable Series Supplement
as may be appropriate. Every such temporary Pass Through Certificate shall be
executed and authenticated by the Pass Through Trustee upon the same conditions
and in substantially the same manner, and with like effect, as the definitive
Pass Through Certificates of such Series. Without unreasonable delay the
Company shall furnish definitive Pass Through Certificates for such Series and
thereupon temporary Pass Through Certificates shall be surrendered in exchange
therefor without charge at any office or agency to be maintained by the Pass
Through Trustee for the purpose pursuant to Section 3.02 hereof, and the Pass
Through Trustee shall execute, authenticate and deliver in exchange for such
temporary Pass Through Certificates such definitive Pass Through Certificates
evidencing a like aggregate Fractional Undivided Interest in the applicable
Pass Through Trust in authorized denominations. Until so exchanged, temporary
Pass Through Certificates shall be entitled to the same benefits under the
applicable Pass

                                       22

<PAGE>

Through Trust and this Pass Through Agreement as definitive Pass Through
Certificates of the applicable Series.

     Section 2.12. Pass Through Certificates Issuable in the Form of a
Registered Global Certificate. For any Series, at the sole option of the
Company as set forth in the related Series Supplement, this Section 2.12 shall
apply to such Series or may be amended with respect to any Series. To the
extent that the provisions of this Section 2.12 conflict with any other
provisions of this Pass Through Agreement, the provisions of this Section 2.12
shall control.

     (a) If the Company shall establish pursuant to Section 2.01(b)(9)
hereof that the Pass Through Certificates of a particular Series are to be
issued in whole in the form of a Registered Global Certificate, then the Pass
Through Trustee shall, in accordance with this Article II, execute,
authenticate and deliver, one or more Registered Global Certificates which (i)
shall represent, and shall be denominated in an amount equal to, the aggregate
Fractional Undivided Interests of all of the Pass Through Certificates in the
related Pass Through Trust, (ii) shall be registered in the name of the
Depository or its nominee, (iii) shall be delivered by the Pass Through Trustee
to the Depository or pursuant to the Depository's instruction, and (iv) shall
bear a legend substantially to the following effect: "Unless this Registered
Global Certificate is presented by an authorized representative of The
Depository Trust Company, a New York corporation ("DTC"), to the Pass Through
Trustee or its agent for registration of transfer, exchange or payment, and any
Registered Global Certificate issued is registered in the name of Cede & Co. or
in such other name as is requested by an authorized representative of DTC (and
any payment is made to Cede & Co. or to such other entity as is requested by an
authorized representative of DTC), ANY TRANSFER, PLEDGE, OR OTHER USE HEREOF
FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL inasmuch as the
registered owner hereof, Cede & Co., has an interest herein."

     No Person acquiring a beneficial interest in a Pass Through Certificate
will be entitled to receive a definitive Pass Through Certificate representing
such Person's interest in the Pass Through Trust, except as provided in
subsection (d) below.

     (b) Notwithstanding any other provision of this Section 2.12 or of Section
2.08 hereof, the Registered Global Certificate for any Series may be
transferred, in whole but not in part and in the manner provided in Section
2.08 hereof, by the Depository to a nominee of such Depository or by a nominee
of such Depository to such Depository or another nominee of such Depository or
by such Depository or any such nominee to a successor Depository selected or

                                       23

<PAGE>

approved by the Company upon notice to the Pass Through Trustee or to a nominee
of such successor Depository.

     (c) The Depository shall be an organization registered as a clearing
agency under the Exchange Act and any other applicable statute or regulation.

     (d) If at any time the Depository notifies the Company that it is
unwilling or unable to continue as Depository for such Series or if at any time
the Depository for such Series shall no longer be eligible under subsection (c)
above, and a successor Depository is not appointed by the Company within 90
days after the Company receives such notice or becomes aware of such condition,
as the case may be, this Section 2.12 shall no longer be applicable to the Pass
Through Certificates of such Series and the Pass Through Trustee will execute,
authenticate and deliver Pass Through Certificates of such Series in definitive
registered form without coupons, in authorized denominations, and in an
aggregate Fractional Undivided Interest in the related Pass Through Trust equal
to the Fractional Undivided Interest in the related Pass Through Trust of the
Registered Global Certificate then outstanding in exchange for such Registered
Global Certificate.

     The Company may at any time and in its sole discretion determine that the
Pass Through Certificates of any Series shall no longer be represented by a
Registered Global Certificate and that the provisions of this Section 2.12
shall no longer apply to such Pass Through Certificates. In such event the Pass
Through Trustee, upon receipt of an Officer's Certificate evidencing such
determination by the Company, will notify the Depository of the availability of
such Pass Through Certificates in definitive form and will execute,
authenticate and deliver, Pass Through Certificates of such Series in
definitive registered form without coupons, in authorized denominations and in
an aggregate Fractional Undivided Interest in the related Pass Through Trust
equal to the Fractional Undivided Interest in the related Pass Through Trust of
the Registered Global Certificate then outstanding in exchange for such
Registered Global Certificate. Upon the exchange of the Registered Global
Certificate for such Pass Through Certificates in definitive registered form,
such Registered Global Certificate shall be cancelled by the Pass Through
Trustee. Such Pass Through Certificates in definitive registered form issued in
exchange for the Registered Global Certificate pursuant to this subsection (d)
shall be registered in such names and in such authorized denominations as the
Depository shall instruct the Pass Through Trustee. The Pass Through Trustee
shall deliver such Pass Through Certificates to the Persons in whose names such
Pass Through Certificates are so registered. Upon the issuance of Pass Through
Certificates in definitive registered form without coupons, the Pass Through
Trustee shall recognize the Person in whose name such definitive Pass Through
Certificates are registered in the Register from time to time as
Certificateholders hereunder.

     (e) As long as the Pass Through Certificates of a Series are represented
by a Registered Global Certificate, all distributions for such Series shall be
made to the holder of such Registered Global Certificate as the
Certificateholder of such Series, or to such Persons as such holder may
designate, by wire transfer of immediately available funds on the date such
distributions are due, and the Company shall or shall cause the Pass Through
Trustee to provide to the Depository any notices referred to in the related
Letter of Representations in accordance with such Letter of Representations.

     Section 3.01. Covenants of the Company. (a) The Company will preserve and
maintain all of its rights, privileges and franchises necessary in the normal
conduct of its business; provided that the Company shall not be required to
preserve any right, privilege or franchise if the Company shall reasonably
determine that the loss thereof will not materially adversely affect the
Company's ability to perform its obligations hereunder or under any Series
Supplement.

     (b) The Company shall not (i) consolidate with or merge into any other
corporation under circumstances in which the Company is not the surviving
corporation or (ii) convey, transfer or lease all or substantially all of its
assets as an entirety to any Person, unless the corporation formed by such
consolidation or into which the Company is merged or the Person which acquired
by conveyance, transfer or lease substantially all of the assets of the Company
as an entirety shall be a corporation organized and existing under the laws of
the United States of America or any State or the District of Columbia, and
shall execute and deliver to the Pass Through Trustee an agreement reasonably
satisfactory in form and substance to the Pass Through Trustee containing an
effective assumption by such successor corporation of the due and punctual
performance and observance of each covenant and condition to be performed or
observed by the Company hereunder and under each Series Supplement.

     (c) Upon any consolidation or merger, or any conveyance, transfer or lease
of substantially all the assets of the Company as an entirety in accordance
with this Section 3.01, the successor corporation formed by such consolidation
or the Person 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 hereunder and under each Series
Supplement with the same effect as if such successor corporation or such
Person, as the case may be, had been named as the Company herein and therein.
No such

                                       25

<PAGE>

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 which shall theretofore have become such in the manner prescribed
in this Section 3.01 from its liability hereunder or under any Series
Supplement.

     (d) The Pass Through Trustee shall receive an Opinion of Counsel of
the Company as conclusive evidence that any consolidation, merger, sale, lease
or conveyance, and any assumption complies with the provisions of this Section
3.01 and the Pass Through Trustee shall be entitled to rely upon the same for
all purposes hereof.

     Section 3.02. Offices for Payments; Registrar. So long as any Pass Through
Certificates of a Series remain outstanding, the Pass Through Trustee will
maintain the following for such Series: (a) an office or agency where such Pass
Through Certificates may be presented for payment and (b) a facility or agency
in New York, New York where such Pass Through Certificates may be presented or
surrendered for registration of transfer and for exchange and for redemption as
provided in this Pass Through Agreement (the "Registrar"). Written notice of
the location of each such other office or agency and of any change of location
thereof shall be given by the Pass Through Trustee to the Company, any Owner
Trustees, the Indenture 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 Principal Corporate Trust Office
of the Pass Through Trustee. The Registrar shall keep a register ("Register")
with respect to the Pass Through Certificates of each Series and their transfer
and exchange. The Pass Through Trustee may appoint one or more co-registrars
("Co-Registrars") for any Series and may terminate any such appointment at any
time upon written notice. The term "Registrar" includes any Co-Registrar.

     Any Registrar shall be a bank or trust company organized and doing

Trust, all payments or distributions to be made to Certificateholders of any

Through Certificate agrees that it will look solely to the income and proceeds

Through Trustee shall distribute out of the applicable Certificate Account the
entire amount deposited therein pursuant to Section 5.01(a) hereof by paying to
each Certificateholder of the related Series of record at the close of business
on the Record Date for such Regular Distribution Date (except as provided in

such Certificateholder appearing in the related Register, such
Certificateholder's pro rata share (based on the aggregate Fractional Undivided

Special Payment is to be made pursuant to either of the last two paragraphs of
Section 2.02(b) hereof or if the Pass Through Trustee receives sufficient
notice of such Special Payment, such notice shall be mailed not less than 15
days prior to the date any such Special Payment is scheduled to be distributed.
For any other Special Payment, such notice shall be mailed as soon as
practicable after the Pass Through Trustee has received funds for or notice of
such Special Payment. Such notices of Special Payments shall set forth:

                                       32

     Distribution Date for such Series, the total amount to be received on
     such date for each $1,000 face amount Pass Through Certificate.

If the amount of premium, if any, payable upon the redemption or purchase in
whole of an Equipment Certificate has not been calculated at the time that the
Pass Through Trustee mails the notice of the related 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, for any Pass Through Trust, any cancelable redemption of the related
Equipment Certificates is cancelled, the Pass Through Trustee, as soon as
possible after learning thereof, shall notify by mail each Certificateholder of
the related Series at its address as it appears on the related Register.

     (d) At such time, if ever, as the Pass Through Certificates are issued in
certificated form, for each Pass Through Trust, any Scheduled Payment or
Special Payment to be distributed pursuant to this Article V shall be payable
at the Corporate Trust Office of the Pass Through Trustee or at any office or
agency maintained for such purpose for the related Series pursuant to Section
3.02 hereof, provided that any Scheduled Payment or Special Payment may be
payable at the option of the Pass Through Trustee or its Paying Agent for the
related Series by mailing checks for such Scheduled Payment or Special Payment
payable to or upon the written order of the related Certificateholders entitled
thereto as they appear on the related Register.

     (e) The Pass Through Trustee shall present any Equipment Certificate to
the applicable Related Indenture Trustee on the date of its stated final

redeemed or purchased in whole pursuant to the relevant Indenture.

     Section 5.03. Statements to Certificateholders. (a) On each Regular
Distribution Date and Special Distribution Date, the Pass Through Trustee shall

                                       33

mail to Certificateholders of the related Series a statement, giving effect to
such distribution to be made on such Regular Distribution Date or Special
Distribution Date, as the case may be, setting forth the following information
(as to (i) and (ii) below, for each $1,000 face amount Pass Through
Certificate):

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

         (ii) the amount of such distribution allocable to interest on the
     related Equipment Certificates; and

        (iii) the Pool Balance and the Pool Factor of the related Pass
     Through Trust.

     (b) For each Series, within a reasonable period of time after the end of
each calendar year but not later than the latest date permitted by law, the

calendar year was a Certificateholder of such Series a statement containing the
sum of the amounts determined pursuant to clauses (a)(i) and (a)(ii) of this
Section 5.03 for the related Pass Through Trust for such calendar year or, in
the event such Person was a Certificateholder of such Series during a portion
of such calendar year, for the applicable portion of such year.

     Section 5.04. Investment of Special Payment Moneys. Any money received by
the Pass Through Trustee pursuant to Section 5.01(b) hereof representing a
Special Payment that is not to be promptly distributed shall, to the extent
practicable, be invested by the Pass Through Trustee in Permitted Investments
selected by the Company by written notice to the Pass Through Trustee pending
distribution of such Special Payment pursuant to Section 5.02 hereof. Any
investment made pursuant to this Section 5.04 shall be in such Permitted
Investments having maturities not later than the date that such moneys are
required to be used to make the payment required under Section 5.02 hereof on
the applicable Special Distribution Date and the Pass Through Trustee shall
hold any such Permitted Investments until maturity. The proceeds upon maturity
of any Permitted Investment shall not be reinvested pending distribution. The
Pass Through Trustee shall have no liability with respect to any investment
made pursuant to this Section 5.04, other than by reason of the willful
misconduct or negligence of the Pass Through Trustee. All income and earnings
from such investments shall be distributed on such Special Distribution Date as
part of such Special Payment.

                                       34

     Section 5.05. Withholding Taxes. The Pass Through Trustee shall withhold
any taxes required to be withheld on payments to any Certificateholder of any
Series, except to the extent that such Certificateholder has furnished evidence
reasonably satisfactory to the Pass Through Trustee of any exemption from
withholding claimed by such Certificateholder, and under no circumstances shall
the failure of any such Certificateholder to receive any amounts so withheld
constitute an Event of Default. The Pass Through Trustee agrees to act as such
withholding agent and, in connection therewith, whenever any taxes or similar
charges are required to be withheld with respect to any amounts payable in
respect of the Pass Through Certificates of such Series, to withhold such
amounts and timely pay the same to the appropriate authority in the name of and
on behalf of the Certificateholders of such Series, that it will file any
necessary withholding tax returns or statements when due, and that, as promptly
as possible after the payment thereof, it will deliver to each such
Certificateholder appropriate documentation showing the payment thereof,
together with such additional documentary evidence as any such
Certificateholder of such Series may reasonably request from time to time. The
Pass Through Trustee agrees to file any other information reports as it may be
required to file under law.

     Notwithstanding any provision to the contrary herein, if the Company is
required to pay any withholding tax or any interest or penalty thereon, or to
indemnify an Owner Participant or Owner Trustee pursuant to Section 8.01(c) of
any related Participation Agreement with respect to the Pass Through Trustee's
failure to withhold with respect to any Certificateholder, the Pass Through
Trustee shall be entitled to retain any payments otherwise distributable to
such Certificateholder that was subject to such withholding until such amounts
shall have been recovered in full by the Pass Through Trustee.

                                   ARTICLE VI
                       Concerning the Certificateholders

     Section 6.01. Evidence of Action Taken by Certificateholders. (a) Any
request, demand, authorization, direction, notice, consent, waiver or other
action provided by this Pass Through Agreement to be given or taken by
Certificateholders of any Series may be embodied in and evidenced by one or
more substantially similar instruments signed by such Certificateholders in
person or by an agent duly appointed in writing, and, except as otherwise
expressly provided herein, such action shall become effective when such
instrument or instruments are delivered to the Pass Through Trustee. Proof of
execution of any instrument or of a writing appointing any such agent shall be
sufficient for any purpose of this Pass Through Agreement and (subject to
Sections 8.02 and 8.03

                                       35

<PAGE>

hereof) conclusive in favor of the Pass Through Trustee, if made in the manner
provided in this Article VI.

     (b) For the purpose of determining the Certificateholders of any Series
entitled to vote or consent to any direction, waiver or other action of such
Certificateholders under Section 7.10 or 7.11 hereof, the Company may set a
record date for such vote or consent by specifying such record date in an
Officer's Certificate delivered to the Pass Through Trustee. Notwithstanding
Section 316(c) of the Trust Indenture Act, such record date shall be a date not
more than 15 days prior to the first solicitation of such vote or consent.

     Section 6.02. Proof of Execution of Instruments and of Holding of
Certificates. Subject to Sections 8.02 and 8.03 hereof, the execution of any
instrument by a Certificateholder or its, his or her agent or proxy may be
proved in accordance with such reasonable rules and regulations as may be
prescribed by the Pass Through Trustee. The holding of Pass Through
Certificates shall be proved by the Register or by a certificate of the
Registrar.

     Section 6.03. Certificateholders to Be Treated as Owners. Prior to due
presentment for registration of transfer of any Pass Through Certificate, each
related Indenture Trustee, the Pass Through Trustee, any agent of any such
related Indenture Trustee or the Pass Through Trustee, the Paying Agent, if
any, the Registrar and the Company may deem and treat the Person in whose name
such Pass Through Certificate shall be registered upon the Register as the
absolute owner of such Pass Through Certificate (whether or not such Pass
Through Certificate shall be overdue and notwithstanding any notation of
ownership or other writing thereon) for the purpose of receiving payment on
account of the principal payable with respect to and, subject to the provisions
of this Pass Through Agreement, interest payable with respect to such Pass
Through Certificate and for all other purposes; and neither any such related
Indenture Trustee nor the Pass Through Trustee (nor any agent of any such
related Indenture Trustee or the Pass Through Trustee) nor the Paying Agent, if
any, nor the Registrar nor the Company shall be affected by any notice to the
contrary. All such payments so made to any such Person, or upon such Person's
order, shall be valid, and, to the extent of the sum or sums so paid, effectual
to satisfy and discharge the liability for moneys payable upon any such Pass
Through Certificate.

     Section 6.04. Pass Through Certificates Owned by the Company and Related
Owner Trustees Deemed Not Outstanding. In determining whether the
Certificateholders of the requisite aggregate Fractional Undivided Interest of
Pass Through Certificates of any Series have concurred in any direction,
consent or waiver under this Pass Through Agreement, Pass Through Certificates
of such

                                       36

<PAGE>

Series that are owned by the Company, any Related Owner Trustee or Related
Owner Participant or any obligor on such Pass Through Certificates or by any
Affiliate of the Company, any such Related Owner Trustee or Related Owner
Participant or any obligor on such Pass Through Certificates shall be
disregarded and deemed not to be Outstanding for the purpose of any such
determination; provided that for the purpose of determining whether the Pass
Through Trustee shall be protected in relying on any such direction, consent or
waiver, only if a Responsible Officer of the Pass Through Trustee has actual
knowledge that certain Pass Through Certificates are so owned shall such Pass
Through Certificates be so disregarded; and provided further that if all Pass
Through Certificates of such Series that would be deemed Outstanding in the
absence of the foregoing provision are owned by the Company, any Related Owner
Trustee or Related Owner Participant or any obligor on such Pass Through
Certificates or by any Affiliate of the Company, any such Related Owner Trustee
or Related Owner Participant or any obligor on such Pass Through Certificates,
then such Pass Through Certificates shall be deemed Outstanding for the purpose
of any such determination. Pass Through Certificates so owned that have been
pledged in good faith may be regarded as Outstanding if the pledgee establishes
to the satisfaction of the Pass Through Trustee the pledgee's right so to act
with respect to such Pass Through Certificates and that the pledgee is not the
Company, any Related Owner Trustee or Related Owner Participant or any obligor
upon the Pass Through Certificates or any Affiliate of the Company, any Related
Owner Trustee or Related Owner Participant or any obligor on such Pass Through
Certificates. In case of a dispute as to such right, the advice of counsel
shall be full protection in respect of any decision made by the Pass Through
Trustee in accordance with such advice.

     For any Series, upon request of the Pass Through Trustee, the Company, the
Related Owner Trustees and the Related Owner Participants promptly shall
furnish to the Pass Through Trustee an Officer's Certificate listing and
identifying all Pass Through Certificates of such Series, if any, known by the
Company or any such Related Owner Trustee or Related Owner Participant to be
owned or held by or for the account of any of the above-described persons; and
the Pass Through Trustee shall be entitled to accept such Officer's Certificate
as conclusive evidence of the facts set forth therein and of the fact that all
Pass Through Certificates of such Series not listed therein are Outstanding for
the purpose of any such determination. For the purpose of determining whether
Pass Through Certificates of a Series are Outstanding as described in this
Section 6.04, an "obligor" on such Pass Through Certificates shall include any
obligor or any Affiliate of any such obligor on any Equipment Certificates that
constitute Trust Property of the related Pass Through Trust.

     Section 6.05. Right of Revocation of Action Taken. For any Series, at any
time prior to (but not after) the evidencing to the Pass Through Trustee, as
provided in Section 6.01 hereof, of any action taken by the related
Certificateholders of the percentage in aggregate of Fractional Undivided
Interests in the related Pass Through Trust specified in this Pass Through
Agreement in connection with such action, any Certificateholder of a Pass
Through Certificate of such Series, the serial number of which is shown by the
evidence to be included among the outstanding serial numbers of the Pass
Through Certificates of such Series, the Certificateholders of which have
consented to such action, may, by filing written notice at the Corporate Trust
Office and upon proof of holding as provided in this Article VI, revoke such
action so far as concerns such Pass Through Certificate. Except as aforesaid,
any such action taken shall be conclusive and binding upon such
Certificateholder for such Pass Through Certificate and upon all future
Certificateholders and owners of such Pass Through Certificate and of any Pass
Through Certificates issued in exchange or substitution therefor, irrespective
of whether or not any notation in regard thereto is made upon any such Pass
Through Certificate or otherwise. Any action taken by such Certificateholders
of the percentage in aggregate of Fractional Undivided Interests in the related
Pass Through Trust specified in this Pass Through Agreement in connection with
such action shall be conclusively binding upon the Pass Through Trustee and all
the Certificateholders of such Series.

     Section 6.06. ERISA. Unless otherwise specified in the applicable Series
Supplement, no employee benefit plan subject to Title I of the Employee
Retirement Income Security Act of 1974, as amended ("ERISA"), or individual
retirement account or plan subject to Section 4975 of the Code (hereinafter
collectively referred to as an "ERISA Plan"), may acquire or hold any of the
Pass Through Certificates. If the Pass Through Certificates are not described
in the applicable Series Supplement as being eligible for purchase by ERISA
Plans, the purchase by any person of any Pass Through Certificate constitutes a
representation by such person to the Company, the Related Owner Participants,
the Related Owner Trustees, the Related Indenture Trustees and the Pass Through
Trustee that such person is not an ERISA Plan and that such person is not
acquiring, and has not acquired, such Pass Through Certificate with assets of
an ERISA Plan.

                                  ARTICLE VII
            Remedies of Pass Through Trustee and Certificateholders

     Section 7.01. Events of Default. (a) Exercise of Remedies. If, for any
Pass Through Trust, an Indenture Event of Default under an Indenture relating
to any Equipment Certificate that constitutes Trust Property of such Pass
Through Trust (an "Event of Default") shall occur and be continuing, then,
subject to the provisions of any Intercreditor Agreement, the Pass Through
Trustee may vote all of the Equipment Certificates under such Indenture held by
such Pass Through Trust, and upon the direction of the Majority In Interest of
Certificateholders of the related Series, the Pass Through Trustee shall vote a
corresponding majority of such Equipment Certificates in favor of directing the
applicable Related Indenture Trustee to declare the unpaid principal of such
Equipment Certificates then outstanding, together with interest accrued but
unpaid thereon and all other amounts due under such Equipment Certificates and
the related Indenture, to be due and payable under, and in accordance with the
provisions of, such Indenture. In addition, if such Event of Default shall have
occurred and be continuing, subject to the provisions of any Intercreditor
Agreement, the Pass Through Trustee may in accordance with such related
Indenture vote such Equipment Certificates to direct the applicable Related
Indenture Trustee regarding the exercise of remedies provided in such
Indenture.

     If, for any Pass Through Trust, an Event of Default shall have occurred
and be continuing, subject to the provisions of any Intercreditor Agreement,
the Pass Through Trustee may, and upon the direction of the Majority In
Interest of Certificateholders of the related Series shall, by such officer or
agent as it may appoint, sell, convey, transfer and deliver any Equipment
Certificates held in such Pass Through Trust that are subject to the
corresponding Indenture Event of Default, without recourse to or warranty by
the Pass Through Trustee or any Certificateholder of such Series, to any
Person. In any such case, the Pass Through Trustee shall sell, assign, contract
to sell or otherwise dispose of and deliver any such Equipment Certificates in
one or more parcels at public or private sale or sales, at any location or
locations at the option of the Pass Through Trustee, all upon such terms and
conditions as it may reasonably deem advisable and at such prices as it may
reasonably deem advisable, for cash.

     If the Pass Through Trustee so decides or is required to sell or otherwise
dispose of any Equipment Certificates pursuant to this Section 7.01, the Pass
Through Trustee shall take such of the actions described above as it may
reasonably deem most effective to complete the sale or other disposition of
such Equipment Certificates, so as to provide for the payment in full of all
amounts due on such Equipment Certificates with respect to the related Series.
Notwithstanding the foregoing, any action taken by the Pass Through Trustee

                                               39

<PAGE>

under this Section 7.01 shall not, in the reasonable judgment of the Pass
Through Trustee, be adverse to the best interests of the Certificateholders of
such Series.

     If an Intercreditor Agreement is applicable and the Pass Through Trustee
is the Controlling Party thereunder, the Pass Through Trustee upon the
occurrence of an Indenture Event of Default may direct the exercise of remedies
in connection therewith.

     (b) Purchase Rights of Certificateholders. If an Intercreditor Agreement
is applicable, by acceptance of its Pass Through Certificate, each
Certificateholder agrees that at any time after the occurrence and during the
continuation of a Triggering Event, with ten days' written notice to the Pass
Through Trustee and each other Certificateholder of the same class, each
Certificateholder of Pass Through Certificates of a Series will have certain
rights, the exercise of which will be specified in the applicable Series
Supplement, to purchase all, but not less than all, of the class of Pass
Through Certificates senior to the Pass Through Certificates held by the
purchasing Certificateholder. The purchase price with respect to the Pass
Through Certificates of any series shall be equal to the Pool Balance of the
Pass Through 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
Pass Through Agreement, any Intercreditor Agreement or any other Indenture
Document or on or in respect of the Pass Through Certificate of such Series;
provided, however, that no such purchase of Pass Through Certificates of such
Series shall be effective unless the purchaser shall certify to the Pass
Through Trustee that contemporaneously with such purchase, such purchaser is
purchasing, pursuant to the terms of this Pass Through Agreement and the other
Agreements, if any, relating to Pass Through Certificates of a series that are
subject to the same Intercreditor Agreement (such other Agreements, the "Other
Agreements"), the Pass Through Certificates of each such series that is senior
to the Pass Through Certificates held by such purchaser.

     If prior to the end of the ten-day period, any other Certificateholder
of the same class notifies the purchasing Certificateholder that the other
Certificateholder wants to participate in such purchase, then such other
Certificateholder may join with the purchasing Certificateholder to purchase
the Pass Through Certificates pro rata based on the interest in the Pass
Through Trust held by each Certificateholder.

     Each payment of the purchase price of the Pass Through Certificates of any
Series shall be made to an account or accounts designated by the Pass Through
Trustee and each such purchase shall be subject to the terms of this Section.
Each Certificateholder of any Series agrees by its acceptance of Pass

                                       40

<PAGE>

Through Certificates of such Series that it will, upon payment from any such
Certificateholders of Pass Through 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 Pass Through Agreement, any Intercreditor
Agreement, the Liquidity Facility, the Indenture Documents and all Pass Through
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 Pass Through Agreement, any Intercreditor Agreement, the
Liquidity Facility and the Indenture Documents. The Pass Through Certificates
of such Series will be deemed to be purchased on the date of payment of the
purchase price is made notwithstanding the failure of the Certificateholders to
deliver any Pass Through Certificates of such Series and, upon such a purchase,
(i) the only rights of the Certificateholders will be to deliver the Pass
Through Certificates to the purchaser and receive the purchase price for such
Pass Through Certificates of such series and (ii) if the purchaser shall so
request, such Certificateholder will comply with all of the provisions of
Section 2.08 hereof to enable new Pass Through 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 Pass
Through Certificates shall be borne by the purchaser thereof.

     Section 7.02. Incidents of Sale of Equipment Certificates. Upon any sale
of all or any part of the Equipment Certificates held in any Pass Through Trust
made either under the power of sale given under this Pass Through Agreement or
the related Series Supplement or otherwise for the enforcement of this Pass
Through Agreement and the related Series Supplement, the following shall be
applicable:

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

          (2) Receipt of Pass Through Trustee Shall Discharge Purchaser.
     The receipt of the Pass Through Trustee or of the officer making such sale
     shall be a sufficient discharge to any purchaser for its, his or her
     purchase

                                               41

<PAGE>

     money, and, after paying such purchase money and receiving such
     receipt, such purchaser or its, his or her 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 Pass Through Trustee upon any sale made either under the power of
     sale given by this Pass Through Agreement or the related Series
     Supplement or otherwise for the enforcement of the related Pass Through
     Trust, shall be deposited and distributed as a Special Payment as provided
     in Article V hereof.

     Section 7.03. Pass Through Trustee May Prove Debt. If any amount payable
under any Equipment Certificate held by any Pass Through Trust is not paid when
due and payable, the Pass Through Trustee, in its own name and as trustee of an
express trust, as holder of such Equipment Certificate shall be, to the extent
permitted by and in accordance with the terms of the related Indenture
Documents and any Intercreditor Agreement, entitled and empowered to institute
any action or proceedings at law or in equity for the collection of the sums so
due and unpaid, and may prosecute any such action or proceedings to judgment or
final decree, and may enforce any such judgment or final decree against the
applicable Owner Trustee, in the case of an Equipment Trust Certificate, or the
Company, in the case of an Equipment Purchase Certificate, or other obligor
upon such Equipment Certificate and collect in the manner provided by law out
of the property of such Owner Trustee, or the Company or such other obligor
upon such Equipment Certificate, as the case may be, wherever situated, the
moneys adjudged or decreed to be payable.

     All rights of action and of asserting claims under this Pass Through
Agreement, or under any of the Pass Through Certificates, may be prosecuted and
enforced by the Pass Through Trustee without the possession of any of such Pass
Through Certificates or the production thereof in any trial or other
proceedings relative thereto, and any such action or proceedings instituted by
the Pass Through Trustee shall be brought in its own name as trustee of an
express trust, and any recovery of judgment, subject to the payment of the
expenses, disbursements and compensation of the Pass Through Trustee, each
predecessor Pass Through Trustee and their respective agents and attorneys,
shall be for the ratable benefit of the Certificateholders of the related
Series.

     In any proceedings brought by the Pass Through Trustee (and also any
proceedings involving the interpretation of any provision of this Pass Through
Agreement, any Series Supplement or any Intercreditor Agreement to which the
Pass Through Trustee shall be a party) the Pass Through Trustee shall be held
to

                                       42

<PAGE>

represent all the Certificateholders of the related Series, and it shall not be
necessary to make any such Certificateholders parties to any such proceedings.

     Section 7.04. Remedies Cumulative. Each and every right, power and remedy
given to the Pass Through Trustee or to any of the Certificateholders of any
Series specifically or otherwise under any Pass Through Trust shall be
cumulative and shall be in addition to every other right, power and remedy
specifically given thereunder or now or hereafter existing at law, in equity or
by statute, and each and every right, power and remedy whether specifically
given thereunder or otherwise existing may be exercised from time to time and
as often and in such order as may be deemed expedient by the Pass Through
Trustee or the Certificateholders of the related Series, and the exercise or
the beginning of the exercise of any power or remedy shall not be construed to
be a waiver of the right to exercise at the same time or thereafter any other
right, power or remedy. No delay or omission by the Pass Through Trustee or of
any such Certificateholder in the exercise of any right, remedy or power or in
the pursuance of any remedy shall impair any such right, power or remedy or be
construed to be a waiver of any default on the part of the applicable Owner
Trustee, if any, or the Company, as the case may be, or to be an acquiescence
therein.

     Section 7.05. Suits for Enforcement. If an Indenture Event of Default has
occurred, has not been waived and is continuing, the Pass Through Trustee may
in its discretion and subject to its rights of appropriate indemnification
under Sections 7.07 and 8.03 and Article IX hereof, to the extent permitted by
and in accordance with any Intercreditor Agreement and the Indenture Documents,
proceed to protect and enforce its rights and rights of the Certificateholders
of the related Series by such appropriate judicial proceedings as the Pass
Through Trustee shall deem most effectual to protect and enforce any of such
rights, either at law or in equity or in bankruptcy or otherwise, whether for
the specific enforcement of any covenant or agreement under the related Pass
Through Trust or in aid of the exercise of any power granted thereunder or to
enforce any other legal or equitable right vested in the Pass Through Trustee
or the Certificateholders under such Pass Through Trust or by law; provided
that any sale of any portion of the related Trust Property shall be made in
accordance with Section 7.02 hereof.

     Section 7.06. Discontinuance of Proceedings. If the Pass Through Trustee
or any Certificateholder of any Series institutes any proceeding to enforce any
right, power or remedy under the related Pass Through Trust, and such
proceeding is discontinued or abandoned for any reason or is determined
adversely to the Pass Through Trustee or such Certificateholder, then and in
every such case the applicable Owner Trustee, if any, and the applicable
Indenture Trustee, the Pass Through Trustee, the Certificateholders of such
Series and the

                                       43

<PAGE>

Company shall, subject to any determination in such proceeding, be restored to
their former positions and rights under such Pass Through Trust with respect to
the Trust Property and all rights, remedies and powers of the Pass Through
Trustee and such Certificateholders shall continue as if no such proceeding had
been instituted.

     Section 7.07. Limitations on Suits by Certificateholders. No
Certificateholder of any Series shall have any right by virtue or by availing
of any provision of the related Pass Through Trust to institute any action or
proceeding at law or in equity or in bankruptcy or otherwise upon or under or
with respect to such Pass Through Trust, or for the appointment of a trustee,
receiver, liquidator, custodian or other similar official or for any other
remedy thereunder, unless such Certificateholder previously has notified the
Pass Through Trustee in writing of an Event of Default under such Pass Through
Trust and of the continuance thereof, as provided herein, and the
Certificateholders of the related Pass Through Certificates then Outstanding
(or the proxy therefor) representing in the aggregate not less than 50% of the
Fractional Undivided Interests of Pass Through Certificates then Outstanding
under such Pass Through Trust have requested in writing that the Pass Through
Trustee institute such action or proceedings in its own name as trustee under
such Pass Through Trust and have offered to the Pass Through Trustee such
reasonable indemnity as it may require against the costs, expenses and
liabilities to be incurred therein or thereby, and the Pass Through Trustee for
60 days after its receipt of such notice, request and offer of indemnity has
failed to institute any such action or proceedings and no direction
inconsistent with such written request has been given to the Pass Through
Trustee pursuant to Section 7.10 hereof; it being understood and intended, and
being expressly covenanted by such Certificateholder with every other
Certificateholder of such Series and the Pass Through Trustee, that no one or
more Certificateholders of such Series shall have any right in any manner
whatever to affect, disturb or prejudice the rights of any other
Certificateholder of such Series or to obtain or seek to obtain priority over
or preference to any other Certificateholder of such Series or to enforce any
right under the related Pass Through Trust, except in the manner provided
therein and for the equal, ratable and common benefit of all Certificateholders
of such Series. For the protection and enforcement of the provisions of this
Section 7.07, each and every Certificateholder of the related Series and the
Pass Through Trustee shall be entitled to such relief as can be given either at
law or in equity.

     Section 7.08. Unconditional Right of Certificateholders to Receive
Principal, Interest and Premium, and to Institute Certain Suits.
Notwithstanding any other provision in this Pass Through Agreement, any Series
Supplement or any Pass Through Certificate issued pursuant to such Series
Supplement, but subject to any Intercreditor Agreement, the right of any
Certificateholder of the

                                       44

<PAGE>

related Series to receive distributions on such Pass Through Certificate of
Scheduled Payments or Special Payments pursuant to Article V hereof on or after
the respective due dates set forth in such Series Supplement, or, subject to
Section 7.07 hereof, to institute suit for the enforcement of any such
distribution on or after such respective dates as provided herein or therein,
shall not be impaired or affected without the consent of such
Certificateholder. The purchase by any Certificateholder of any Pass Through
Certificate constitutes the consent of such Certificateholder to the retention
by the Pass Through Trustee of certain amounts otherwise distributable to such
Certificateholder in accordance with Section 5.05 hereof.

     Section 7.09. Control by Certificateholders. Subject to any Intercreditor
Agreement, a Majority In Interest of Certificateholders of any Series has the
right with respect to the related Pass Through Trust to direct the Pass Through
Trustee as to the time, method, and place of conducting any proceeding for any
remedy available to the Pass Through Trustee with respect to such Pass Through
Trust or pursuant to the terms of any Intercreditor Agreement, or exercising
any trust or power conferred on the Pass Through Trustee under this Pass
Through Agreement or any Intercreditor Agreement, including any right of the
Pass Through Trustee as Controlling Party under any Intercreditor Agreement or
as holder of the Equipment Certificates; provided that such direction is not
otherwise than in accordance with law and the provisions of such Pass Through
Trust and the Pass Through Trustee has received, to the extent provided in
Sections 7.07 and 8.03 and Article IX hereof, such reasonable indemnification
as it may require against the costs, expenses and liabilities to be incurred by
the Pass Through Trustee; and provided further that the Pass Through Trustee
has the right to decline to follow any such direction if the Pass Through
Trustee, being advised by counsel, determines that the action or proceeding so
directed may not lawfully be taken or if the Pass Through Trustee in good faith
by its board of directors, the executive committee, or a trust committee of
directors or Responsible Officers of the Pass Through Trustee determines that
the action or proceedings so directed would involve the Pass Through Trustee in
personal liability or if the Pass Through Trustee in good faith so determines
that the actions or forebearances specified in or pursuant to such direction
would be unduly prejudicial to the interests of the Certificateholders of such
Series not joining in the giving of said direction, it being understood that
the Pass Through Trustee shall have no duty to ascertain whether or not such
actions or forebearances are unduly prejudicial to such Certificateholders.

     Nothing in this Pass Through Agreement or any Series Supplement shall
impair the right of the Pass Through Trustee in its discretion to take any
action deemed proper by the Pass Through Trustee with respect to the related
Pass

                                       45

<PAGE>

Through Trust and which is not inconsistent with such direction by
Certificateholders of the related Series.

     Section 7.10. Waiver of Past Events of Default. Subject to any
Intercreditor Agreement, the Majority in Interest of Certificateholders of any
Series (i) may on behalf of all of the Certificateholders waive any past Event
of Default under the related Pass Through Trust or the related Series
Supplement and its consequences or (ii) if the Pass Through Trustee is the
Controlling Party, may direct the Pass Through Trustee to instruct the
applicable Indenture Trustee to waive, any past Indenture Default under any
Indenture and its consequences, and thereby annul any direction given by such
Certificateholders or the Pass Through Trustee to such Indenture Trustee with
respect thereto. Upon such waiver such Event of Default will cease to exist and
any Event of Default arising therefrom will be deemed to have been cured for
every purpose of such Pass Through Trust, but no such waiver will extend to any
subsequent or other Event of Default thereunder or impair any right consequent
thereon; provided that any such waiver will be effective to waive any such past
Event of Default and its consequences as described above if, but only if, the
correlative Indenture Event of Default has been waived under the related
Indenture by the requisite holders of the Equipment Certificates outstanding
thereunder; and provided further that in the absence of written instructions
from all Certificateholders of any Series (or the proxy therefor), the Pass
Through Trustee shall not waive any Event of Default (i) consisting of the
failure to pay any principal of, or premium (if any), or interest on, or other
amounts due under, any Equipment Certificate held by the related Pass Through
Trust and the consequent failure to distribute any related Scheduled Payment or
Special Payment pursuant to Article V hereof on or after the respective due
date therefor set forth in the related Series Supplement or (ii) in respect of
a covenant or provision under any Pass Through Trust that, under Article XI
hereof or the related Series Supplement, cannot be modified or amended without
the consent of each Certificateholder of the related Series (or the proxy
therefor).

     Section 7.11. Notice of Pass Through Defaults. The Pass Through Trustee
shall, in the manner and to the extent required by Section 313(c) of the Trust
Indenture Act, notify the Certificateholders of any Series of all Pass Through
Defaults under the related Pass Through Trust known to a Responsible Officer of
the Pass Through Trustee, unless such Pass Through Defaults have been cured
before the giving of such notice; provided that under no circumstances shall
the Pass Through Trustee give such notice until the earlier of the time at
which such Pass Through Default becomes an Event of Default or the expiration
of a period of 60 days from the occurrence of such Pass Through Default; and
provided further that, except in the case of the failure to pay any principal
of or interest on or any other amount due under any of the Equipment
Certificates held

                                       46

<PAGE>

by any Pass Through Trust and the consequent failure to distribute any related
Scheduled Payment or Special Payment pursuant to Article V hereof on or after
the respective due date therefor set forth in the related Series Supplement,
the Pass Through 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 or trustees or Responsible Officers of the Pass Through
Trustee in good faith determines that the withholding of such notice is in the
interests of the Certificateholders of the related Series.

                                  ARTICLE VIII
                      Concerning the Pass Through Trustee

     Section 8.01. Acceptance by Pass Through Trustee. The Pass Through
Trustee, upon the execution and delivery of a Series Supplement creating a Pass
Through Trust and providing for the issuance of a Series of Pass Through
Certificates, shall acknowledge its acceptance of all right, title and interest
in and to the Equipment Certificates to be acquired as Trust Property of such
Pass Through Trust pursuant to the applicable Participation Agreements and
Section 2.02 hereof, and shall declare that the Pass Through Trustee holds and
will hold such right, title, and interest, together with all other property
constituting the Trust Property of such Pass Through Trust, for the benefit of
all then present and future Certificateholders of such Series, upon the trusts
set forth in such Pass Through Trust.

     Section 8.02. Pass Through Trustee's Liens. The Pass Through Trustee
agrees that it will, in its individual capacity and at its own cost and expense
(without any right of indemnity in respect of any such cost or expense under
Article IX hereof) promptly take such action as may be necessary to duly
discharge all Liens on any part of the Trust Property of any Pass Through Trust
that result from claims (i) against it in its individual capacity not related
to the administration of such Trust Property or any other transaction pursuant
to this Pass Through Agreement, the related Series Supplement, the
Participation Agreement or any Intercreditor Agreement, or (ii) against it as
Pass Through Trustee hereunder or in its individual capacity which arise out of
the negligence or willful misconduct of the Pass Through Trustee as such
negligence or willful misconduct shall be determined by a final decision of a
court of competent jurisdiction.

     Section 8.03. Certain Rights of the Pass Through Trustee. Subject to the
Trust Indenture Act:

                                       47

<PAGE>

     (a) the Pass Through Trustee may rely and shall be protected in acting or
refraining from acting upon any resolution, Officer's Certificate or any other
certificate, statement, instrument, opinion, report, notice, request, consent,
order, bond, debenture, note, coupon, security or other paper or document
believed by it to be genuine and to have been signed or presented by the proper
party or parties;

     (b) any request of any Related Indenture Trustee or Related Owner Trustee
in connection with any Pass Through Trust shall be sufficiently evidenced by an
Officer's Certificate (unless other evidence in respect thereof is specifically
prescribed herein) upon which the Pass Through Trustee may rely to prove or
establish a matter set forth therein;

     (c) the Pass Through Trustee in the administration of this Pass Through
Agreement or any Intercreditor Agreement may consult with counsel and any
advice or Opinion of Counsel shall be full and complete authorization and
protection in respect of any action taken, suffered or omitted to be taken by
it hereunder in good faith and in accordance with such advice or Opinion of
Counsel;

     (d) the Pass Through Trustee shall not be obligated to exercise any of the
trusts or powers vested in it under any Pass Through Trust or any Intercreditor
Agreement at the request, order or direction of the Certificateholders of the
related Series in accordance with the provisions thereof, unless such
Certificateholders have offered to the Pass Through Trustee reasonable security
or indemnity against the costs, expenses and liabilities which might be
incurred therein or thereby;

     (e) the Pass Through Trustee shall not be liable for any action taken or
omitted by it in good faith and believed by it to be authorized or within the
discretion, rights or powers conferred upon it under any Pass Through Trust,
under this Pass Through Agreement or under any Intercreditor Agreement;

     (f) prior to the occurrence of an Event of Default under any Pass Through
Trust and after the curing or waiving of all Events of Default thereunder, the
Pass Through Trustee shall not be bound to make any investigation into the
facts or matters stated in any resolution, certificate, statement, instrument,
opinion, report, notice, request, consent, order, approval, appraisal, bond,
debenture, note, security, or other paper or document unless requested in
writing to do so by the Majority in Interest of Certificateholders of the
related Series; provided that if the payment within a reasonable time to the
Pass Through Trustee of the costs, expenses or liabilities likely to be
incurred by it in the making of such investigation is, in the opinion of the
Pass Through Trustee, not reasonably assured to the Pass Through Trustee by the
security afforded to it by the terms of such Pass Through Trust, the Pass
Through Trustee may require reasonable

                                       48

<PAGE>

indemnity from the Certificateholders against such expenses or liabilities as a
condition to proceeding; subject to (h) below, the reasonable expenses of every
such examination shall be paid by the Pass Through Trustee or any predecessor
trustee, and shall be repaid by the Company upon demand or indemnification by
the Certificateholders;

     (g) the Pass Through Trustee may execute any of the trusts or powers under
any Pass Through Trust or any Intercreditor Agreement or perform any duties
hereunder or thereunder either directly or by or through agents or attorneys
not regularly in its employ and the Pass Through Trustee shall not be
responsible for any misconduct or negligence on the part of any such agent or
attorney appointed by it with due care under this Pass Through Agreement or any
Intercreditor Agreement; and

     (h) the Pass Through Trustee shall not be required to expend or risk its
own funds or otherwise incur personal financial liability in the performance of
any of its duties or in the exercise of any of its rights or powers under any
Pass Through Trust, if the Pass Through Trustee has determined in good faith
that the repayment of such funds or adequate indemnity against such liability
is not reasonably assured to it.

     Section 8.04. Pass Through Trustee Not Responsible for Recitals. The
Pass Through Trustee assumes no responsibility for the correctness of the
recitals contained herein or in any Pass Through Certificates, except for the
execution and authentication of such Pass Through Certificates by the Pass
Through Trustee in accordance with Sections 2.05 and 2.06 hereof, respectively.

     Section 8.05. Pass Through Trustee and Agents May Hold Pass Through
Certificates; Collections. The Pass Through Trustee and any agent of the Pass
Through Trustee, in its individual or any other capacity, may become the owner
or pledgee of Pass Through Certificates with the same rights it would have if
it were not the Pass Through Trustee or such agent and, subject to the
applicable provisions of the Trust Indenture Act, may otherwise deal with the
Company, any Related Indenture Trustee or Related Owner Trustee and receive,
collect, hold and retain collections therefrom with the same rights it would
have if it were not the Pass Through Trustee or such agent.

     Section 8.06. Moneys Held by Pass Through Trustee. Subject to Sections
5.04 and 12.04 hereof, all moneys received by the Pass Through Trustee shall,
until used or applied as provided herein, be held in trust for the purposes for
which they were received, but need not be segregated from other funds except to
the extent required by mandatory provisions of law. Subject to Section 5.04

                                       49

<PAGE>

hereof, neither the Pass Through Trustee nor any agent thereof shall be under
any liability for interest on any moneys received by it hereunder.

     Section 8.07. Right of Pass Through Trustee to Rely on Officer's
Certificate. Subject to Section 8.03 hereof, whenever in the administration of
any Pass Through Trust the Pass Through Trustee shall deem it necessary or
desirable that a matter be proved or established prior to taking or suffering
or omitting any action thereunder, such matter (unless other evidence in
respect thereof is specifically prescribed herein) may, in the absence of bad
faith on the part of the Pass Through Trustee, be deemed to be conclusively
proved and established by an Officer's Certificate delivered to the Pass
Through Trustee by the Company, any Related Indenture Trustee or any Related
Owner Trustee, as the case may be, and such certificate, in the absence of bad
faith on the part of the Pass Through Trustee, shall be full warrant to the
Pass Through Trustee for any action taken, suffered or omitted by it under the
provisions of this Pass Through Agreement upon the faith thereof.

     Section 8.08. Compensation. The Company agrees to pay, and the Pass
Through Trustee shall be entitled to receive, reasonable compensation and
payment or reimbursement for its reasonable advances, expenses and
disbursements (including the reasonable compensation and expenses and
disbursements of its counsel, agents and other persons not regularly in its
employ) incurred in connection with its services rendered hereunder or in any
way relating to or arising out of the administration of any Pass Through Trust
or the related Trust Property, except any such advance, expense or disbursement
attributable to the Pass Through Trustee's negligence, willful misconduct or
bad faith or incurred as a result of the breach of its representation, warranty
or covenant set forth in Sections 3.03(iv) and 8.02 hereof, and shall have a
priority claim on such Trust Property for the payment of such compensation,
advances, expenses and disbursements to the extent that such compensation,
advances, expenses and disbursements shall not be paid by the Company.

     In addition, the Pass Through Trustee shall be entitled to reimbursement
from, and shall have a priority claim on, all property and funds held or
collected by the Pass Through Trustee with respect to any Series or the related
Pass Through Trust in its capacity as Pass Through Trustee 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 Pass Through
Trust (excluding any taxes payable by the Pass Through Trustee on or measured
by any compensation received by the Pass Through Trustee for its services under
this Pass Through Agreement), including any costs and expenses incurred in
contesting the imposition of any such tax. If the Pass Through Trustee
reimburses itself from the Trust Property of such Pass Through Trust for any
such tax it shall

                                       50

<PAGE>

within 20 days mail a brief report setting forth the circumstances thereof to
all Certificateholders of the related Series as their names and addresses
appear in the related Register.

                                   ARTICLE IX
             Indemnification of Pass Through Trustee by the Company

     The Company hereby agrees to assume liability for, and does hereby
indemnify, save and keep harmless the Pass Through Trustee, in its individual
capacity, and its successors, assigns, agents and servants, with respect to the
claims of the Pass Through Trustee for payment or reimbursement under Section
8.08 hereof and from and against any and all liabilities, losses, damages,
penalties, taxes (excluding any taxes payable by the Pass Through Trustee on or
measured by any compensation received by the Pass Through Trustee for its
services under this Pass Through Agreement), claims, actions, suits, costs,
expenses or disbursements (including legal fees and expenses) of any kind and
nature whatsoever which may be imposed on, or incurred by, the Pass Through
Trustee in its individual capacity in any way relating to or arising out of
this Pass Through Agreement, or any Series Supplement or the enforcement of any
of the terms of any thereof, or in any way relating to or arising out of the
administration of any Pass Through Trust or the related Trust Property or the
action or inaction of the Pass Through Trustee hereunder, except only (i) in
the case of negligence, willful misconduct or bad faith of the Pass Through
Trustee in the performance of its duties hereunder or under any Series
Supplement, (ii) as may result from the inaccuracy of any representation or
warranty of the Pass Through Trustee herein or in any Participation Agreement
or (iii) as otherwise provided in Section 8.02 hereof.

     The Pass Through Trustee in its individual capacity shall be entitled to
indemnification, from the related Trust Property, for any liability, loss,
damage, penalty, claim, action, suit, cost, expense or disbursement indemnified
against pursuant to this Article IX to the extent not reimbursed by the Company
or others, but without releasing any of them from their respective agreements
of reimbursement; and to secure the same the Pass Through Trustee shall have a
prior Lien on such Trust Property. The indemnities contained in this Article IX
shall survive the termination of this Pass Through Agreement or any Pass
Through Trust and the resignation or removal of the Pass Through Trustee
hereunder or thereunder.

                                       51

                               Successor Trustees

     Section 10.01. Resignation and Removal of Pass Through Trustee;
Appointment of Successor. (a) The Pass Through Trustee may resign at any time
as trustee of any Pass Through Trust without cause by giving at least 45 days
prior written notice to the Company, the Related Indenture Trustees and the
Related Owner Trustees, if any, such resignation to be effective upon the
acceptance of the trusteeship by a successor Pass Through Trustee. In addition,
a Majority in Interest of Certificateholders of any Series or the Company may
at any time remove the related Pass Through Trustee without cause by an
instrument in writing delivered to the Company (in the case of removal by a
Majority in Interest of Certificateholders of any Series), the Related Owner
Trustees, if any, the Related Indenture Trustees and the Pass Through Trustee,
and the Pass Through Trustee shall promptly notify each Certificateholder of
such Series of such removal in writing, such removal to be effective upon the
acceptance of the trusteeship by a successor Pass Through Trustee.

     In the case of the resignation or removal of the Pass Through Trustee, the
Company or a Majority in Interest of Certificateholders of the related Series
may appoint a successor Pass Through Trustee by an instrument signed by the
Company or such Certificateholders, as the case may be.

     If a successor Pass Through Trustee shall not have been appointed within
90 days after such notice of resignation or removal, the Pass Through Trustee,
the Company or any Certificateholder of the related Series may apply to any
court of competent jurisdiction to appoint a successor Pass Through Trustee to
act until such time, if any, as a successor shall have been appointed as
provided above. The successor Pass Through Trustee so appointed by such court
shall immediately and without further act be superseded by any successor Pass
Through Trustee appointed by the Company or a Majority in Interest of
Certificateholders as provided above within one year from the date of the
appointment by such court.

     (b) If at any time any of the following occurs with respect to any Pass
Through Trust:

          (i) the Pass Through Trustee fails to comply with the requirements of
     Section 310(G) of the Trust Indenture Act after written request for
     such compliance by any Certificateholder of the related Series who has
     been a bona fide Certificateholder of such Series for at least six
     months;

                                       52

<PAGE>

         (ii) the Pass Through Trustee ceases to be eligible in accordance with
     the provisions of Section 10.02 hereof to act as trustee for such Pass
     Through Trust and fails to resign after written request for such
     resignation by the Company or by any such bona fide Certificateholder;
     or

        (iii) the Pass Through Trustee becomes incapable of acting, or shall be
     adjudged a bankrupt or insolvent, or a receiver or liquidator of the
     Pass Through Trustee or of its property shall be appointed, or any
     public officer takes charge or control of the Pass Through Trustee or
     of its property or affairs for the purpose of rehabilitation,
     conservation or liquidation;

then the Company may remove the Pass Through Trustee and appoint a successor
trustee by written instrument, one copy of which instrument shall be delivered
to the Pass Through Trustee so removed and one copy to the successor trustee,
or, subject to the provisions of Section 315(e) of the Trust Indenture Act, any
Certificateholder of the related Series who has been a bona fide
Certificateholder of such Series for at least six months may, on behalf of
itself and all others similarly situated, petition any court of competent
jurisdiction for the removal of the Pass Through Trustee and the appointment of
a successor trustee. Such court may thereupon, after such notice, if any, as it
may deem proper and prescribe, remove the Pass Through Trustee and appoint a
successor trustee, which removal and appointment shall become effective upon
acceptance of appointment by the successor trustee as provided in Section 10.03
hereof. The successor Pass Through Trustee so appointed by such court shall
immediately and without further act be superseded by any successor Pass Through
Trustee appointed by the Company or the Certificateholders of the related
Series as provided in subsection (a) above within one year from the date of
appointment by such court.

     (c) If a Responsible Officer of the Pass Through Trustee shall obtain
actual knowledge of an Avoidable Tax (as hereinafter defined) in respect of any
Pass Through Trust which has been or is likely to be asserted, the Pass Through
Trustee shall promptly notify the Company and shall, within 30 days of such
notification, resign as Pass Through Trustee of such Pass Through Trust
hereunder unless within such 30-day period the Pass Through Trustee shall have
received notice that the Company has agreed to pay such tax. The Company shall
promptly appoint a successor Pass Through Trustee of such Pass Through Trust in
a jurisdiction where there are no Avoidable Taxes. As used herein, an
"Avoidable Tax" in respect of such Pass Through Trust means a state or local
tax: (i) upon (w) such Pass Through Trust, (x) such Trust Property, (y)
Certificateholders of such Pass Through Trust or (z) the Pass Through Trustee
for which the Pass Through Trustee is entitled to seek reimbursement from the
Trust Property of such Pass Through Trust, and (ii) which would be avoided if
the Pass

Through 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
Pass Through Trust if the Company or any Owner Trustee shall agree to pay, and
shall pay, such tax.

     Section 10.02. Persons Eligible for Appointment as Pass Through Trustee.
Each Pass Through Trust shall at all times have a Pass Through Trustee which
shall be a Person eligible to act as trustee under Section 310(a) of the Trust
Indenture Act and shall be a corporation organized and doing business under the
laws of the United States of America or of any State or the District of
Columbia having a combined capital and surplus of at least $100,000,000, or a
direct or indirect subsidiary of such a corporation, or a member of a bank
holding company group, having a combined capital and surplus of at least
$100,000,000 and such subsidiary or member itself having a capital and surplus
of at least $10,000,000, which corporate trustee shall be a citizen of the
United States of America as defined under Title 49 of the United States Code,
as amended, and which is authorized under such laws to exercise corporate trust
powers and is subject to supervision of examination by federal, State or
District of Columbia authority. If such corporation publishes reports of
condition at least annually, pursuant to law or to the requirements of the
aforesaid supervising or examining authority, then for the purposes of this
Section 10.02, 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 condition so published.

     If at any time the Pass Through Trustee ceases to be eligible in
accordance with the provisions of this Section 10.02 to act as trustee for any
Pass Through Trust, the Pass Through Trustee shall resign immediately as Pass
Through Trustee for such Pass Through Trust in the manner and with the effect
specified in Section 10.01 hereof.

     Section 10.03. Acceptance of Appointment by Successor Trustee. Any
successor trustee appointed as provided in Section 10.01 hereof for any Pass
Through Trust shall execute and deliver to the Company and to its predecessor
trustee an instrument accepting such appointment with respect to such Pass
Through Trust, and thereupon the resignation or removal of the predecessor
trustee shall become effective and such successor trustee, without any further
act, deed or conveyance, shall become vested with all rights, powers, duties
and obligations of its predecessor with respect to such Pass Through Trust, as
if such successor trustee was originally named as trustee of such Pass Through
Trust.

     Notwithstanding the foregoing, on the written request of the Company or
the successor trustee, the trustee ceasing to act shall, upon payment of its
charges then unpaid and subject to Section 12.04 hereof, pay over to the
successor trustee

                                       54

<PAGE>

all moneys at the time held by it with respect to such Pass Through Trust and
shall execute and deliver an instrument transferring to such successor trustee
all such rights, powers, duties and obligations. Upon request of any such
successor trustee, the Company shall execute any and all instruments in writing
for more fully and certainly vesting in and confirming to such successor
trustee all such rights and powers. Any trustee ceasing to act shall,
nevertheless, retain a prior claim upon all property or funds held or collected
by such trustee with respect to such Pass Through Trust to secure any amounts
then due it pursuant to the provisions of Article IX hereof.

     If a successor trustee is appointed with respect to one or more (but not
all) of the Pass Through Trusts created pursuant to this Pass Through
Agreement, the predecessor trustee and each successor trustee with respect to
such Pass Through Trusts shall execute and deliver a supplemental agreement
hereto which shall be sufficient with respect to each such Pass Through Trust
to effect the removal of any predecessor trustee retiring and to vest the
successor trustee with all rights, powers, duties and obligations of its
predecessor under each such Pass Through Trust as to which the predecessor Pass
Through Trustee is retiring, as if such successor trustee was originally named
as Pass Through Trustee hereunder or under the applicable Series Supplement,
and shall add to or change any of the provisions of this Pass Through Agreement
and the applicable Series Supplement as shall be necessary to provide for or
facilitate the administration of such Pass Through Trust hereunder by more than
one Pass Through Trustee.

     An institution satisfying the criteria specified in Section 10.02 hereof
may be appointed, including pursuant to the relevant Series Supplement, as the
Pass Through Trustee in respect of any Series issued or proposed to be issued
if such institution shall execute and deliver to the Company with respect to
the relevant Pass Through Trust an instrument (which may be the relevant Series
Supplement) accepting such appointment and shall thereupon become vested with
all the rights, powers, trusts and duties of the Pass Through Trustee in
respect of such Pass Through Trust.

     It is understood that except as provided in Section 10.05 hereof nothing
herein or in any supplemental agreement or Series Supplement shall constitute
any Pass Through Trustee a co-trustee of any Pass Through Trustee and that each
Pass Through Trustee may be the Pass Through Trustee of one or more separate
Pass Through Trusts.

     No institution shall accept appointment as a Pass Through Trustee as
provided in this Section 10.03 unless at the time of such acceptance such
institution shall be eligible under the provisions of Article X hereof to act
as trustee of the relevant Pass Through Trust.

                                       55

<PAGE>

     Upon acceptance of appointment by a successor trustee as provided in this
Section 10.03, the successor trustee shall notify the Certificateholders of the
related Series of such appointment by first-class mail at their last addresses
as they shall appear in the Register, and shall mail a copy of such notice to
the Company, the Related Indenture Trustees and the Related Owner Trustees, if
any. If the acceptance of appointment is substantially contemporaneous with the
resignation, then the notice called for by the preceding sentence may be
combined with the notice called for by Section 10.01 hereof.

     Section 10.04. Merger, Conversion, Consolidation or Succession to Business
of Pass Through Trustee. Any corporation into which the Pass Through 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
Pass Through Trustee is a party, or any corporation succeeding to the corporate
trust business of the Pass Through Trustee, shall be the successor to the Pass
Through Trustee hereunder, provided that, anything herein to the contrary
notwithstanding, such corporation shall be eligible under the provisions of
Section 10.02 hereof to act as trustee hereunder, without the execution or
filing of any paper or any further act on the part of any of the parties
hereto.

     If, with respect to any Pass Through Trusts at the time of such succession
to the Pass Through Trustee, any of the Pass Through Certificates of the
related Series have been authenticated but not delivered, such successor may
adopt the certificate of authentication of any such predecessor Pass Through
Trustee and deliver such Pass Through Certificates so authenticated; and, if at
that time any of such Pass Through Certificates have not been authenticated,
such successor may authenticate such Pass Through Certificates either in the
name of any of its predecessor or in its own name as the successor Pass Through
Trustee; and in all such cases such certificate of authentication shall have
the full force of the certificate of authentication of the Pass Through Trustee
set forth in Section 2.01 hereof; provided that the right to adopt the
certificate of authentication of any predecessor Pass Through Trustee or to
authenticate Pass Through Certificates in the name of any predecessor Pass
Through Trustee shall apply only to its successor or successors by merger,
conversion or consolidation.

     Section 10.05. Appointment of Separate Pass Through Trustees. (a) At any
time or times, for the purpose of meeting any legal requirements of any
jurisdiction in which any part of the Trust Property of any Pass Through Trust
may at the time be located or in which any action of the Pass Through Trustee
may be required to be performed or taken, the Pass Through Trustee, by an
instrument in writing signed by it, may appoint one or more individuals or
corporations to act as separate trustee or separate trustees or co-trustee,
acting jointly with the Pass Through Trustee, of all or any part of such Trust
Property, to

                                       56

<PAGE>

the full extent that local law makes it necessary for such separate trustee or
separate trustees or co-trustee, acting jointly with the Pass Through Trustee,
to act.

     (b) The Pass Through Trustee and, at the request of the Pass Through
Trustee, the Company, shall execute, acknowledge and deliver all such
instruments as may be required by the legal requirements of any jurisdiction or
by any such separate trustee or separate trustees or co-trustee for the purpose
of more fully confirming such title, rights or duties to such separate trustee
or separate trustees or co-trustee. Upon the acceptance in writing of such
appointment by any such separate trustee or separate trustees or co-trustee,
it, he, she or they shall be vested with such title to such Trust Property or
any part thereof, and with such rights, powers, duties and obligations, as
shall be specified in the instrument of appointment, and such rights, powers,
duties and obligations shall be conferred or imposed upon and exercised or
performed by the Pass Through Trustee, or the Pass Through Trustee and such
separate trustee or separate trustees or co-trustee jointly with the Pass
Through Trustee subject to all the terms of this Pass Through Agreement, except
to the extent that under any law of any jurisdiction in which any particular
act or acts are to be performed the Pass Through Trustee shall be incompetent
or unqualified to perform such act or acts, in which event such rights, powers,
duties and obligations shall be exercised and performed by such separate
trustee or separate trustees or co-trustee, as the case may be.

     Any separate trustee or separate trustees or co-trustee may, at any time
by an instrument in writing, constitute the Pass Through Trustee its, her or
his attorney-in-fact and agent with full power and authority to do all acts and
things and to exercise all discretion on its, her or his behalf and in its, her
or his name. In case any such separate trustee or co-trustee shall die, become
incapable of acting, resign or be removed, the title to any Trust Property and
all assets, property, rights, powers, duties and obligations and duties of such
separate trustee or co-trustee shall, so far as permitted by law, vest in and
be exercised by the Pass Through Trustee, without the appointment of a
successor to such separate trustee or co-trustee unless and until a successor
is appointed.

     (c) All provisions of this Pass Through Agreement which are for the
benefit of the Pass Through Trustee (including without limitation Article IX
hereof) shall extend to and apply to each separate trustee or co-trustee
appointed pursuant to the foregoing provisions of this Section 10.06.

     (d) For any Pass Through Trust, every additional trustee and separate
trustee hereunder shall, to the extent permitted by law, be appointed and act
and the Pass Through Trustee shall act, subject to the following provisions and
conditions:

                                       57

<PAGE>

          (i) all powers, duties, obligations and rights conferred upon the
     Pass Through Trustee in respect of the receipt, custody, investment
     and payment of moneys shall be exercised solely by the Pass Through
     Trustee;

         (ii) all other rights, powers, duties and obligations conferred or
     imposed upon the Pass Through Trustee shall be conferred or imposed
     and exercised or performed by the Pass Through Trustee and such
     additional trustee or trustees and separate trustee or trustees
     jointly except to the extent that under any law of any jurisdiction in
     which any particular act or acts are to be performed, the Pass Through
     Trustee shall be incompetent or unqualified to perform such act or
     acts, in which event such rights, powers, duties and obligations
     (including the holding of title to the Trust Property in any such
     jurisdiction) shall be exercised and performed by such additional
     trustee or trustees or separate trustee or trustees;

        (iii) no power hereby given to, or exercisable by, any such additional
     trustee or separate trustee shall be exercised hereunder by such
     additional trustee or separate trustee except jointly with, or with
     the consent of, the Pass Through Trustee; and

         (iv) no trustee hereunder shall be personally liable by reason of any
     act or omission of any other trustee hereunder.

         If at any time the Pass Through Trustee shall deem it no longer
necessary or prudent in order to conform to any such law, the Pass Through
Trustee shall execute and deliver all instruments and agreements necessary or
proper to remove any additional trustee or separate trustee.

     (e) Any request, approval or consent in writing by the Pass Through
Trustee to any additional trustee or separate trustee shall be sufficient
warrant to such additional trustee or separate trustee, as the case may be, to
take such action as may be so requested, approved or consented to.

     (f) Notwithstanding any other provision of this Section 10.06, the powers
of any additional trustee or separate trustee shall not exceed those of the
Pass Through Trustee hereunder.

     Section 10.06. Preferential Claims. Reference is made to Section 311 of
the Trust Indenture Act. For purposes of Section 311(b)(4) and (6) of such Act:

     (a) "cash transaction" means any transaction in which full payment for
goods or securities sold is made within seven days after delivery of the goods
or

                                       58

<PAGE>

securities in currency or in checks or other orders drawn upon banks or bankers
and payable upon demand; and

     (b) "self-liquidating paper" means any draft, bill of exchange, acceptance
or obligation which is made, drawn, negotiated or incurred by the Company for
the purpose of financing the purchase, processing, manufacturing, shipment,
storage or sale of goods, wares or merchandise and which is secured by
documents evidencing title to, possession of, or a lien upon, the goods, wares
or merchandise or the receivables or proceeds arising from the sale of the
goods, wares or merchandise previously constituting the security, provided the
security is received by the Trustee simultaneously with the creation of the
creditor relationship with the Company arising from the making, drawing,
negotiating or incurring of the draft, bill of exchange, acceptance or
obligation.

or immunities under this Pass Through Agreement, any Series Supplement or
otherwise, whether in its official or individual capacity.

executed without the consent of the Certificateholders of the Outstanding Pass
Through Certificates of any Series, notwithstanding any of the provisions of
Section 11.02 hereof.

changing in any manner or eliminating any of the provisions of this Pass

Section 6.01 hereof, the Pass Through Trustee shall join with the Company in
the execution of such supplemental agreement unless such supplemental agreement
affects the Pass Through Trustee's own rights, duties or immunities under this
Pass Through Agreement or the related Series Supplement or otherwise, in which
case the Pass Through Trustee may in its discretion, but shall not be obligated
to, enter into such supplemental agreement.

     It shall not be necessary for the consent of the Certificateholders of any
Series under this Section 11.02 to approve the particular form of any proposed
supplemental agreement, but it shall be sufficient if such consent shall
approve the substance thereof.

     Promptly after the execution by the Company and the Pass Through Trustee
of any supplemental agreement relating to any Pass Through Trust pursuant to
the provisions of this Section 11.02, the Pass Through Trustee shall mail a
notice thereof by first-class mail to the related Certificateholders at their
addresses as they shall appear on the related Register, setting forth in

thereafter be determined, exercised and enforced hereunder and thereunder
subject in all respects to such modifications and amendments, and all the terms
and conditions

                                       62

<PAGE>

of any such supplemental agreement shall be and be deemed to be part of the
terms and conditions of this Pass Through Agreement and such Pass Through Trust
for any and all purposes.

     Section 11.04. Documents to Be Given to Trustee. The Pass Through Trustee,
subject to the provisions of Sections 8.02 and 8.03 hereof, may receive and

Through Agreement and any applicable Series Supplement.

Supplemental Agreements. Pass Through Certificates of any Series authenticated
and delivered after the execution of any supplemental agreement relating to
such Series pursuant to the provisions of this Article XI may bear a notation

so determine, new Pass Through Certificates for such Series so modified as to
conform, in the opinion of the Company and the Pass Through Trustee, to any
modification of this Pass Through Agreement contained in any such supplemental
agreement may be provided by the Company, executed and authenticated by the
Pass Through Trustee and delivered in exchange for the Outstanding Pass Through

thereof conform to the provisions of the Trust Indenture Act as in force on
such date.

waiver becomes effective, a consent to it by a Certificateholder is a
continuing consent by such Certificateholder and every subsequent
Certificateholder of the related Pass Through Certificate, even if notation of
the consent is not made on such Pass Through Certificate. However, any such
Certificateholder or subsequent Certificateholder may revoke the consent as to
its, his or her Pass Through Certificate if the Pass Through Trustee receives
the notice of revocation before the date the amendment or waiver becomes
effective. After an amendment or waiver becomes effective, it shall bind every
Certificateholder affected by such amendment or waiver.

     Section 11.08. Amendments, Waivers, Etc. of Related Indenture Documents.
If the Pass Through Trustee, as holder of any Equipment Certificate in trust
for the benefit of the Certificateholders of any Series or as Controlling
Party, receives a request for a consent to any modification, amendment or

                                       63

give any consent, waiver, authorization or approval under such related
Indenture or such other related Indenture Documents, the Pass Through Trustee
shall forthwith notify each Certificateholder of such Series, as shown on the
related Register as of such date, of such request. Such notice shall request
instructions from such Certificateholders with respect to such request. Subject
to Section 7.10 hereof, the Pass Through Trustee shall, as the holder of such
Equipment Certificate, consent or vote with respect thereto in the same
proportion as so instructed by the respective Certificateholders of the related
Pass Through Certificates. Notwithstanding the foregoing, but subject to
Section 7.09 hereof and any Intercreditor Agreement, if an Event of Default
shall have occurred and be continuing, the Pass Through Trustee may, in its own
discretion and at its own direction, consent and notify the Related Indenture
Trustee of such consent to any modification, amendment, supplement or waiver
under any related Indenture Document.

                                       64

Through Trustee shall notify the related Registrar at the time such
Certificateholders are notified of such final distribution. Upon presentation
and surrender of the Pass Through Certificates of such Series, the Pass Through
Trustee shall distribute all amounts distributable on such Pass Through
Certificates on such Distribution Date pursuant to Section 5.02 hereof.

     Section 12.02. Application by Pass Through Trustee of Funds Deposited for

such moneys have been deposited with the Pass Through Trustee, of all sums due

funds except to the extent required by law.

     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 Pass Through Trustee shall
give a second written notice to the remaining Certificateholders of such Series
to surrender their Certificates for cancellation and to receive the final
distribution with respect thereto.

     Section 12.03. Repayment of Moneys Held by Paying Agent. In connection
with the satisfaction and discharge of any Pass Through Trust, all moneys then
held by any Paying Agent for such Pass Through Trust shall, upon demand of the
Pass Through Trustee, be repaid to it and thereupon such Paying Agent shall be
released from all further liability with respect to such moneys.

     Section 12.04. Transfer of Moneys Held by Pass Through Trustee and Paying
Agent Unclaimed for Two Years and Eleven Months. Any moneys deposited with or

                                 Miscellaneous

     Section 13.01. Capacity in Which Acting. The Pass Through Trustee acts
hereunder and under any Pass Through Trust not in its individual capacity but
solely as trustee except as expressly provided herein or in the related Series
Supplement.

     Section 13.02. No Legal Title to Trust Property in Certificateholders. No
Certificateholder of any Series shall have legal title to any part of the Trust
Property of the related Pass Through Trust. No transfer, by operation of law or
otherwise, of any Pass Through Certificate or other right, title and interest
of any Certificateholder in and to such Trust Property or under the related
Pass Through Trust shall operate to terminate such Pass Through Trust or
entitle such Certificateholder or any successor or transferee of such
Certificateholder to an accounting or to the transfer to it of legal title to
any part of such Trust Property.

     Section 13.03. Certificates Nonassessable and Fully Paid. No
Certificateholder of any Series shall be personally liable for obligations of
the related Pass Through Trust, the Fractional Undivided Interests represented
by the Pass Through Certificates of such Series shall be nonassessable for any
losses or expenses of such Pass Through Trust or for any reason whatsoever, and
upon authentication of such Pass Through Certificates by the Pass Through
Trustee pursuant to Section 3.02 hereof, such Pass Through Certificates will be
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 Pass Through Trust, or the obligations of the parties hereto, nor
shall anything set forth herein, in the related Series Supplement or in the
related Pass Through Certificates be construed so as to constitute the
Certificateholders of such Series from time to time as partners or members of
an association.

     Section 13.04. Pass Through Agreement for the Benefit of the Company, the
Pass Through Trustee and the Certificateholders. Nothing in this Pass Through
Agreement, in any Series Supplement or in any Pass Through Certificate, whether
express or implied, shall be construed to give to any person other than the
Company, the Pass Through Trustee, as trustee and in its individual capacity,
and the Certificateholders of the respective related Series any legal or
equitable right,

     66

<PAGE>

remedy or claim under or in respect of this Pass Through Agreement, any Pass
Through Trust or any such Pass Through Certificate.

     Section 13.05. Limitation on Rights of Certificateholders. The death or
incapacity of any Certificateholder of any Series shall not operate to
terminate this Pass Through Agreement or the related Pass Through 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 such Pass Through Trust, nor otherwise affect the
rights, obligations, and liabilities of the parties hereto or any of them. No
Certificateholder of any Series shall be entitled to revoke the related Pass
Through Trust.

     Section 13.06. Notices. Unless otherwise expressly specified or permitted
by the terms hereof or the applicable Series Supplement with respect to any
Pass Through Trust, all notices, requests, demands, authorizations, directions,
consents, waivers or documents provided or permitted by this Pass Through
Agreement or such Series Supplement to be made, given, furnished or filed with
respect to such Pass Through Trust shall be in writing, mailed by certified
mail, postage prepaid, or by confirmed facsimile, and (i) if to the Pass
Through Trustee, addressed to it at its Principal Corporate Trust Office,
telephone (801) 246-5053, facsimile (801) 246-5630 or (ii) if to the Company,
addressed to it at its office at 942 Shady Grove Road, Memphis, Tennessee
38120, Attention: Vice President and Treasurer, facsimile (901) 818-7246 with a
copy to Senior Vice President and General Counsel at 1980 Nonconnah Boulevard,
Memphis, Tennessee 38132, telephone (901) 395-3388, facsimile (901) 395-4758,
and as to any Series, as otherwise specified in the Series Supplement related
thereto. The Company or the Pass Through Trustee as to any Series, by notice to
the other, may designate additional or different addresses for subsequent
notices or communications. Any party hereto may change the address to which
notices to such party will be sent by giving notice of such change to the other
party to this Pass Through Agreement.

     Where this Pass Through Agreement or any Series Supplement provides for
notice to Certificateholders of any Series, such notice shall be sufficiently
given (unless otherwise expressly provided herein) if in writing and mailed,
first-class postage prepaid, to each such Certificateholder entitled thereto,
at his or her last address as it appears in the related Register. In any case
where notice to Certificateholders of any Series is given by mail, neither the
failure to mail such notice, nor any defect in any notice so mailed, to any
particular Certificateholder shall affect the sufficiency of such notice with
respect to other Certificateholders of such Series. Where this Pass Through
Agreement or any Series Supplement provides for notice in any manner, such
notice may be waived in writing by the person entitled to receive such notice,
either before or after the event, and such waiver shall be the equivalent of
such notice. Waivers of notice by

                                       67

<PAGE>

Certificateholders shall be filed with the Pass Through Trustee, but such
filing shall not be a condition precedent to the validity of any action taken
in reliance upon such waiver.

     In case, by reason of the suspension of or irregularities in regular mail
service, it shall be impracticable to mail notice to any Certificateholders
when such notice is required to be given pursuant to any provision of this Pass
Through Agreement or any related Series Supplement, then any manner of giving
such notice as shall be satisfactory to the Pass Through Trustee shall be
deemed to be a sufficient giving of such notice.

     Section 13.07. Officer's Certificate and Opinion of Counsel; Statements to
Be Contained Therein. Upon any application or demand by the Company to the Pass
Through Trustee to take any action, the Company shall furnish to the Pass
Through Trustee (i) an Officer's Certificate stating that all conditions
precedent, if any, provided for in this Pass Through Agreement and the
applicable Series Supplement relating to the proposed action have been complied
with and that the proposed action is in conformity with the requirements of
this Pass Through Agreement and such Series Supplement, or (ii) an Opinion of
Counsel stating that in the opinion of such counsel all such conditions
precedent, if any, have been complied with, except that in the case of any such
application or demand as to which the furnishing of such documents is
specifically required by any provision of this Pass Through Agreement or such
Series Supplement relating to such particular application or demand, no
additional certificate or opinion need be furnished.

     Each certificate or opinion required by this Pass Through Agreement or any
Series Supplement and delivered to the Pass Through Trustee with respect to
compliance with a condition or covenant provided for in this Pass Through
Agreement or such Series Supplement, except for the certificate required by
Section 4.03(d) hereof shall include (a) a statement that the person making
such certificate or opinion has read such covenant or condition, (b) a brief
statement as to the nature and scope of the examination or investigation upon
which the statements or opinions contained in such certificate or opinion are
based, (c) a statement that, in the opinion of such person, he or she has made
such examination or investigation as is necessary to enable him or her to
express an informed opinion as to whether or not such covenant or condition has
been complied with and (d) a statement as to whether or not, in the opinion of
such person, such condition or covenant has been complied with.

     Any certificate, statement or opinion of counsel may be based, insofar as
it relates to factual matters information with respect to which is in the
possession of the Company, upon the certificate, statement or opinion of or
representations by

                                       68

<PAGE>

an officer or officers of the Company unless such counsel knows that the
certificate, statement or opinion or representations with respect to the
matters upon which his or her certificate, statement or opinion may be based as
aforesaid are erroneous, or in the exercise of reasonable care should know that
the same are erroneous.

     Any certificate, statement or opinion of an officer of the Company or of
counsel thereto may be based, insofar as it relates to accounting matters, upon
a certificate or opinion of or representations by an accountant or firm of
accountants employed by the Company unless such officer or counsel, as the case
may be, knows that the certificate or opinion or representations with respect
to the accounting matters upon which such certificate, statement or opinion may
be based as aforesaid are erroneous, or in the exercise of reasonable care
should know that the same are erroneous.

     Any certificate or opinion of any independent firm of public accountants
filed with the Pass Through Trustee shall contain a statement that such firm is
independent.

     Section 13.08. Conflict of Any Provision of Pass Through Agreement with
the Trust Indenture Act. If and to the extent that any provision of this Pass
Through Agreement limits, qualifies or conflicts with another provision
included in this Pass Through Agreement by operation of Sections 310 to 317,
inclusive, of the Trust Indenture Act (an "incorporated provision"), such
incorporated provision shall control.

     Section 13.09. Severability. Any provision of this Pass Through Agreement
or any Series Supplement which is prohibited or unenforceable in any
jurisdiction shall, as to such jurisdiction, be ineffective to the extent of
such prohibition or unenforceability without invalidating the remaining
provisions hereof or thereof, and any such prohibition or unenforceability in
any jurisdiction shall not invalidate or render unenforceable such provision in
any other jurisdiction.

     Section 13.10. No Oral Modifications or Continuing Waivers. No terms or
provisions of this Pass Through Agreement, any Series Supplement, or any Pass
Through Certificates may be changed, waived, discharged or terminated orally,
but only by an instrument in writing signed by the party or other person
against whom enforcement of the change, waiver, discharge or termination is
sought; and any waiver of the terms hereof or thereof shall be effective only
in the specific instance and for the specific purpose given.

     Section 13.11. Successors and Assigns. All covenants and agreements
contained herein shall be binding upon, and inure to the benefit of, each of
the parties hereto and the successors and permitted assigns of each, all as
herein provided. Any request, notice, direction, consent, waiver or other
instrument or action by any Certificateholder shall bind the successors and
assigns of such Certificateholder.

     Section 13.12. Headings. The headings of the various Articles and Sections
herein and in the table of contents hereto are for the convenience of reference
only and shall not define or limit any of the terms or provisions hereof.

     Section 13.13. Normal Commercial Relations. Anything contained in this
Pass Through Agreement to the contrary notwithstanding, the Pass Through
Trustee and any Certificateholder, or any bank or other affiliate of any such
party, may conduct any banking or other financial transactions, and have
banking or other commercial relationships, with the Company fully to the same
extent as if this Pass Through Agreement were not in effect, including without
limitation the making of loans or other extensions of credit to the Company for
any purpose whatsoever, whether related to any of the transactions contemplated
hereby or otherwise.

     Section 13.14. Governing Law; Counterpart Form. THIS PASS THROUGH
AGREEMENT SHALL IN ALL RESPECTS BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE
WITH, THE LAW OF THE STATE OF NEW YORK, INCLUDING ALL MATTERS OF CONSTRUCTION,
VALIDITY AND PERFORMANCE. This Pass Through Agreement may be executed by the
parties hereto in separate counterparts, each of which when so executed and
delivered shall be an original, but all such counterparts shall together
constitute but one and the same instrument.

     Section 13.15. Distributions Due on Days Other than Business Days. If, for
any Pass Through Trust, any Distribution Date is not a Business Day, then such
distribution need not be made on such date, but may be made on the next
succeeding Business Day with the same force and effect as if made on the
applicable Distribution Date, and no interest shall accrue for the intervening
period.

     Section 13.16. Registration of Equipment Certificates in Name of
Subordination Agent. If a Pass Through Trust is party to an Intercreditor
Agreement, the Pass Through Trustee agrees that all Equipment Certificates to
be purchased by such Pass Through Trust shall be issued in the name of the
Subordination Agent under such Intercreditor Agreement or its nominee and held
by such Subordination Agent in trust for the benefit of the Certificateholders,
or, if

                                       70

not so held, such Subordination Agent or its nominee shall be reflected as the

                     [Reverse of Pass Through Certificate]

     The Pass Through Certificates do not represent a direct obligation of, or
an obligation guaranteed by, or an interest in, the Company or the Pass Through
Trustee or any affiliate thereof. The Pass Through Certificates are limited in
right of payment, all as more specifically set forth on the face hereof and in
the Pass Through Agreement, any Intercreditor Agreement, any Liquidity Facility
and the Series Supplement. Subject to the Intercreditor Agreement, all payments
or distributions made to Certificateholders under the Pass Through Agreement
shall be made only from the Trust Property and only to the extent that the Pass
Through Trustee shall have sufficient income or proceeds from the Trust
Property to make such payments in accordance with the terms of the Pass Through
Agreement and the Series Supplement. Each Certificateholder of this Pass
Through 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 Pass Through
Agreement, any Intercreditor Agreement, any Liquidity Facility and the Series
Supplement.

     In connection with withholding taxes, under certain circumstances the Pass
Through Trustee may retain certain amounts otherwise distributable to a
Certificateholder. The purchase by any Certificateholder of any Pass Through
Certificate constitutes the consent of such Certificateholder to such retention
in accordance with the terms of the Pass Through Agreement.

     This Pass Through Certificate does not purport to summarize the Pass
Through Agreement, any Intercreditor Agreement, any Liquidity Facility and the
Series Supplement and reference is made to the Pass Through Agreement, any
Intercreditor Agreement, any Liquidity Facility and the Series Supplement for
information with respect to the interests, rights, benefits, obligations,
proceeds and duties evidenced hereby. A copy of the Pass Through Agreement, any
Intercreditor Agreement, any Liquidity Facility and the Series Supplement may
be examined by any Certificateholder upon request during normal business hours
at the Principal Corporate Trust Office of the Pass Through Trustee, and at
such other places designated by the Pass Through Trustee.

     As of the date of issuance of this Pass Through Certificate, and assuming
that no prepayment or default in respect of payment on the Equipment

                     [Reverse of Pass Through Certificate]

     The Pass Through Certificates do not represent a direct obligation of, or
an obligation guaranteed by, or an interest in, the Company or the Pass Through
Trustee or any affiliate thereof. The Pass Through Certificates are limited in
right of payment, all as more specifically set forth on the face hereof and in
the Pass Through Agreement, any Intercreditor Agreement, any Liquidity Facility
and the Series Supplement. Subject to the Intercreditor Agreement, all payments
or distributions made to Certificateholders under the Pass Through Agreement
shall be made only from the Trust Property and only to the extent that the Pass
Through Trustee shall have sufficient income or proceeds from the Trust
Property to make such payments in accordance with the terms of the Pass Through
Agreement and the Series Supplement. Each Certificateholder of this Pass
Through 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 Pass Through
Agreement, any Intercreditor Agreement, any Liquidity Facility and the Series
Supplement.

     In connection with withholding taxes, under certain circumstances the Pass
Through Trustee may retain certain amounts otherwise distributable to a
Certificateholder. The purchase by any Certificateholder of any Pass Through
Certificate constitutes the consent of such Certificateholder to such retention
in accordance with the terms of the Pass Through Agreement.

     This Pass Through Certificate does not purport to summarize the Pass
Through Agreement, any Intercreditor Agreement, any Liquidity Facility and the
Series Supplement and reference is made to the Pass Through Agreement, any
Intercreditor Agreement, any Liquidity Facility and the Series Supplement for
information with respect to the interests, rights, benefits, obligations,
proceeds and duties evidenced hereby. A copy of the Pass Through Agreement, any
Intercreditor Agreement, any Liquidity Facility and the Series Supplement may
be examined by any Certificateholder upon request during normal business hours
at the Principal Corporate Trust Office of the Pass Through Trustee, and at
such other places designated by the Pass Through Trustee.

     As of the date of issuance of this Pass Through Certificate, and assuming
that no prepayment or default in respect of payment on the Equipment
Certificates shall occur and assuming there will be no change in the payment
terms of the Equipment Certificates, the aggregate scheduled repayments of
principal on the Equipment Certificates for the Pass Through Trust and the
resulting Pool Factors for the Pass Through Trust after taking into account
each such repayment are set forth below:

     The Pass Through Agreement, any Intercreditor Agreement, any Liquidity
Facility and the Series Supplement permit, with certain exceptions provided
therein, the amendment thereof and the modification of the rights and
obligations of the Company and the rights of the Certificateholders under the
Pass Through Trust at any time by the Company and the Pass Through Trustee with
the consent of the Majority In Interest of Certificateholders in the Pass
Through Trust. Any such consent by the Certificateholder of this Pass Through
Certificate shall be conclusive and binding on such Certificateholder and upon
all future Certificateholders of this Pass Through Certificate and of any Pass
Through 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 Pass
Through Certificate. The Pass Through Agreement, any Intercreditor Agreement,
any Liquidity Facility and the Series Supplement also permit the amendment
thereof, in certain limited circumstances, without the consent of the
Certificateholders of any of the Pass Through Certificates.

     As provided in the Pass Through Agreement and the Series Supplement and
subject to certain limitations set forth therein, the transfer of this Pass
Through Certificate is registrable in the Register upon surrender of this Pass
Through Certificate for registration of transfer to the Pass Through 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
Pass Through 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 Pass Through Certificates of authorized denominations
evidencing the same aggregate Fractional Undivided Interest in the Pass Through
Trust will be issued to the designated transferee or transferees.

     The Pass Through Certificates are issuable only as registered Pass Through
Certificates without coupons in minimum denominations of $1,000 fractional
undivided interests and integral multiples thereof. As provided in the Pass
Through Agreement and the Series Supplement and subject to certain limitations
set forth therein, the Pass Through Certificates are exchangeable for new Pass
Through Certificates of authorized denominations evidencing the same aggregate
Fractional Undivided Interest in the Pass Through Trust, as requested by the
Certificateholder surrendering the same.

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

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

     The obligations and responsibilities created by the Pass Through Agreement
and the Series Supplement and the Pass Through Trust created thereby shall
terminate upon the distribution to Certificateholders of all amounts required
to be distributed to them pursuant to the Pass Through Agreement, any
Intercreditor Agreement, any Liquidity Facility and the Series Supplement and
the disposition of all property held as part of the Trust Property.

                        1998 INCENTIVE STOCK OPTION PLAN

        Section 1.01 The purpose of this Incentive Stock Option Plan (the
"Plan") is to promote the growth and general prosperity of First Colonial
Securities Holding Corp. (the "Company") by permitting the Company to grant
options to purchase shares of its common stock (the "Common Stock"), to persons
whose contributions are important to the success of the Company. The Plan is
designed to help attract and retain superior personnel, and to offer them an
additional incentive to contribute to the success of the Company. The Company
intends that options granted to employees, directors, and consultants pursuant
to the provisions of the Plan will quality as "incentive stock options" within
the meaning of Section 422 of the Internal Revenue Code of 1986, as amended (the
"Code") and Treasury Regulations promulgated thereunder ("ISOs"), unless an
option, by its terms, would not qualify thereunder. As used in the Plan, the
terms "corporation" and "subsidiary" shall have the meanings set forth in
subsections (e) and (f), respectively, of Section 424 of the Code.

        Section 2.01 Administration. The Plan shall be administered by the
entire board of directors of the Company or by a committee of the board of
directors consisting of two or more directors to whom administration of the Plan
has been delegated by resolution of the board of directors. The members of the
board or that committee, as the case may be, are hereafter referred to as the
"Plan Administrators". Actions of the Plan Administrators shall be taken by a
majority vote or by unanimous written consent. In the event that the Company is
subject to Section 16 of the Securities Exchange Act of 1934, as amended
("Act"), all Plan Administrators shall be "Non-Employee Directors" within the
meaning of Rule 16b-3(b)(3) of the General Rules and Regulations under the Act,
if less than all the members of the Board are Plan Administrators. In the event
that the Company is the issuer of any common equity securities required to be
registered under Section 12 of the Act, all Plan Administrators shall be
"outside directors" within the meaning of the Regulations underlying Section
162(m) of the Code.

        Section 2.02 Authority of Plan Administrators. Subject to the provisions
of the Plan, and with a view to effecting its purpose, the Plan Administrators
shall have sole authority, in their absolute discretion, (a) to construe and
interpret the Plan, (b) to define the terms used herein, (c) to prescribe,
amend, and rescind rules and regulations relating to the Plan, (d) to determine
the individuals to whom options to purchase Common Stock shall be granted under
the Plan, (e) to determine the time or times at which options shall be granted
under the Plan, (f) to determine the number of shares of Common Stock subject to
each option, the option price, vesting schedule and the duration of each option
granted under the Plan, (g) to determine all of the other terms and conditions
of options granted under the Plan, and (h) to make all other determinations
necessary or advisable for the administration of the Plan and do everything
necessary or appropriate to administer the Plan. All decisions, determinations
and interpretations made by the Plan Administrators shall be binding and
conclusive on all participants in the Plan and on their legal representatives,
heirs and beneficiaries. The Plan Administrators shall endeavor to ensure that
option agreements entered into pursuant to the Plan which are intended to be

                                        1
<PAGE>

ISOs meet all the requirements for incentive stock options described in Section
422 of the Code.

        Section 2.03. Terms, Conditions and Method of Grant. The terms and
conditions of options granted under the Plan may differ from one another as the
Plan Administrators, in their absolute discretion, shall determine as long as
all options granted under the Plan satisfy the requirements of the Plan. All
options granted hereunder shall be evidenced by a written option agreement (with
a copy of the Plan attached) between the Company and the optionee. The option
agreement shall be in the form and shall contain such provisions consistent with
the Plan as the Plan Administrators, acting with the benefit of legal counsel,
shall deem advisable. No option under the Plan shall be granted, the exercise of
which shall be conditioned upon the exercise of any other option under the Plan
or any other plan.

        Section 3.01. Maximum Number of Shares of Common Stock Subject to the
Plan. Subject to the provisions of Section 12.01, the maximum aggregate number
of shares of Common Stock with respect to which options may be granted under the
Plan is one million, five hundred thousand (1,500,000). The maximum number of
shares subject to the Plan may be adjusted pursuant to the provisions of Section
12.02 of the Plan. If any of the options granted under the Plan expire or
terminate for any reason before they have been exercised in full, the
unpurchased Common Stock subject to those expired or terminated options shall
again be available for the purpose of the Plan.

        Section 4.01. Eligibility and Participation. Officers, employees,
directors and consultants of the Company and its subsidiaries shall be eligible
for selection by the Plan Administrators to participate in the Plan.

        Section 5.01. Effective Date and Term of Plan. The Plan shall become
effective upon its adoption by the board of directors of the Company, subject to
approval of the Plan by the stockholders of the Company, as provided in Section
14.01. The Plan shall continue in effect for a term of 10 years unless sooner
terminated under Section 13.01.

        Section 5.02. Duration of Options. Each option and all rights there
under granted pursuant to the terms of the Plan shall expire on the date
determined by the Plan Administrators, but in no event shall any option granted
under the Plan expire later than ten (10) years from the date on which the
option is granted. In addition, each option shall be subject to early
termination as provided in this Plan.

        Section 5.03. Exercise Price. The purchase price for shares of Common
Stock acquired pursuant to the exercise (in whole or in part) of any option (the
"Exercise Price") shall not be less than the fair market value per share of the
Company's Common Stock at the time of the grant of the option. Fair market value
shall be determined by the Plan Administrators on the basis of those factors
they deem appropriate; provided that the Plan Administrators shall make a good
faith effort to determine such fair market value in selecting such factors; and
provided further, that if at the time the determination is made

                                       2
<PAGE>

the Common Stock is admitted to trading on a national securities exchange, the
fair market value of the shares shall be not less than the greater of (i) the
mean between the high bid and low ask prices reported for the Common Stock on
that exchange on the day the option is granted or the most recent trading day
preceding the date on which the option is granted or (ii) the last reported sale
price reported for the Common Stock on that exchange on the day the option is
granted or most recent trading day preceding the date on which the option is
granted. The phrase "national securities exchange" shall include, but not be
limited to, the National Association of Securities Dealers Automated Quotation
System and the over-the-counter market.

        Section 5.04. Term and Exercise Price of Option Granted to More Than Ten
Percent Stockholder. Notwithstanding anything to the contrary in Sections 5.02
and 5.03, an option granted to an optionee who at the time the option is granted
owns (or under Section 424 (d) of the Code is deemed to own) more than 10
percent of the voting power or value of all classes of stock of the Company
shall not be an ISO unless the option, by its terms, shall not be exercisable
after the expiration of five years after the date that option is granted, and
(ii) the Exercise Price for that option shall be at least 110 percent of the
fair market value (as determined under Section 5.03) of the shares subject to
the option at the time the option granted.

        Section 5.05. Maximum Amount of Options to any Optionee. To the extent
that the aggregate fair market value of Common Stock, determined as of the date
of grant, with respect to which options under this Plan and all other such
option plans of the Company (or a parent or subsidiary as defined in Section 424
of the Code), and which would otherwise be ISOs, are exercisable for the first
time by an Optionee in any calendar year exceeds $100,000, such options shall
not be treated as ISOs. Subject to the provisions of Section 12.01, the maximum
aggregate number of shares which may be granted under the Plan to any individual
during any 12-month period is one-half of the number of shares set forth in
Section 3.01, above.

        Section 6.01. Exercise of Options by Optionee. Each option shall be
exercisable in one or more installments during its term, and the right to
exercise may be cumulative as determined by the Plan Administrators. No option
may be exercised for a fraction of a share of Company Stock. In addition, no
option may be exercised other than on a business day of the Company. The full
Exercise Price of any shares purchased shall be paid at the time of exercise in
cash or, if permitted by the terms of the option, any combination of cash or
shares of Common Stock. If any portion of the Exercise Price is paid in shares
of Common Stock, those shares shall be tendered at their then fair market value,
as determined by the Plan Administrators in accordance with Section 5.03 of the
Plan. In addition, if permitted by the terms of the option, the optionee may
purchase all or any portion of the shares subject to an option by directing the
Company to withhold from delivery to the optionee the number of shares having a
fair market value equal to the aggregate exercise price of the total number of
shares purchased. No option may be exercised on a date later than 10 years from
the date it is granted.

        Section 6.02. Exercise of Options by Estate or Beneficiaries. Subject to
the provisions of Section 11.01, if an option shall have been transferred to an
estate of an optionee, or any beneficiary thereof who shall have acquired such
option by bequest or inheritance by reason of the death of such optionee, the
option shall be exercisable in the same manner as if exercised by such optionee
pursuant to Section 6.01. Such options, if so exercised, shall be eligible for
treatment under Section 422 of the Code without regard to whether such executor,
administrator or beneficiary is then employed by the Company, provided the
optionee shall have met the employment requirements of Section 422 of the Code
on the date of his or her death. If an ISO had not been exercised by an optionee
prior to the expiration of the applicable holding period of Section 422(a)(1) of
the Code, the executor, administrator or beneficiary of the estate of such
optionee may exercise such option, and such option shall be treated as an ISO,
notwithstanding whether the shares of Common Stock acquired thereunder shall be
disposed of prior to the expiration of such applicable period.

        Section 6.03. Written Notice Required. Any option granted pursuant to
the terms of the Plan shall be considered exercised when written notice of that
exercise, together with the investment representations described in Section
7.01, if any, have been given to the Company at its principal office by the
person entitled to exercise the option and full payment for the shares with
respect to which the option is exercised has been received by the Company. Upon
receipt thereof, and in connection with the transfer of Common Stock pursuant to
the exercise of an ISO, the Company shall provide optionee with a written
statement containing the information required by Section 6039(a) of the Code.

        Section 7.01 Compliance with State and Federal Laws. Shares of Common
Stock shall not be issued with respect to any option granted under the Plan
unless the exercise of that option and the issuance and delivery of the Common
Stock pursuant to that exercise shall comply with all relevant provisions of
state and federal laws, rules and regulations, and the requirements of any stock
exchange upon which the Common Stock may then be listed, and shall be further
subject to the approval of counsel for the Company with respect to that
compliance. If any law or any regulation of any federal or state body having
jurisdiction shall require the Company or the optionee to take any action in
connection with the shares specified in the optionee' notice, then the date for
the delivery of the shares shall be postponed until the completion of the
necessary action. The Plan Administrators also shall require (to the extent
required by applicable laws, rules and regulations) an optionee to furnish
evidence satisfactory to the Company (including a written and signed
representation letter and a consent to be bound by any transfer restrictions
imposed by law, legend, condition, or otherwise) that the Common Stock is being
purchased only for investment and without any present intention to sell or
distribute the Common Stock in violation of any law, rule or regulation.
Further, each optionee shall consent to the imposition of a legend on the shares
of Common Stock

                                       4

subject to his or her option restricting their transferability as may be
required by applicable laws, rules and regulations.

        Section 8.01. Option Rights Upon Termination of Employment.

        (a) If an optionee's employment with the Company terminates for any
reason, other than as a result of the optionee's death or permanent and total
disability, any unexercised portion of his or her option shall immediately
terminate, unless an option agreement allows the option to be exercised at any
time within 3 months after the date of termination. For this purpose, the
employment in respect of which an option shall have been granted shall be deemed
to continue while the optionee to whom said option shall have been granted shall
be on military leave, leave on account of illness or other bona fide leave
determined in the discretion of the Plan Administrator, provided the period of
such leave shall not exceed 90 days, or if longer, so long as the right of an
optionee who is an employee to reemployment is not so guaranteed by operation of
law or contract, then such employment shall be deemed to terminate on the 91st
day of such leave.

        (b) Nothing in this Plan shall be deemed to obligate the Company to
continue an optionee's employment for any particular time.

        Section 9.01. Option Rights upon Death or Disability. Except as
otherwise limited by the Plan Administrators in the option agreement, if any
optionee dies or becomes permanently and totally dissolved within the meaning of
Section 22(e)(3) of the Code while in the employ of the Company or a subsidiary
thereof, or dies within 3 months following termination of employment, his or her
option shall expire one year after the date of death or the date of permanent
and total disability, unless in either case the option agreement or the Plan
otherwise provides for earlier termination. During that period, the unexercised
portion of the option may be exercised by the optionee, if living, or by the
person or persons to whom the optionee's rights under the option shall pass by
will or by the laws of descent and distribution, but only to the extent that the
optionee was entitled to exercise the option at the date of his or her death or
permanent and total disability, as the case may be.

        Section 10.01. Privileges of Stock Ownership. Notwithstanding the
exercise of any option granted pursuant to the Plan, no optionee shall have any
of the rights or privileges of a stockholder of the Company in respect of any
shares of Common Stock issuable upon the exercise of his or her option until the
optionee becomes a stockholder of record.

        Section 11.01. Options Not Transferable. Options granted pursuant to the
terms of the Plan may not be sold, pledged, assigned or transferred in any
manner other than by will or the laws of descent or distribution and may be
exercised during the lifetime of an optionee only by that optionee.

        Section 12.01. Adjustments for Changes in Capitalization or
Organization; Acceleration of Right to Exercise Option. All options granted
pursuant to this Plan shall be adjusted in the manner prescribed by this
section.

        (a) If the outstanding shares of the Common Stock of the Company are
increased, decreased, changed into, or exchanged for a different number or kind
of shares or securities through recapitalization, reclassification, stock
dividend, stock split or reverse stock split, an appropriate and proportionate
adjustment shall be made in the maximum number and kind of shares of Common
Stock as to which options may be granted under the Plan. A corresponding
adjustment changing the number or kind of shares of Common Stock allocated to
unexercised options or portions thereof, which shall have been granted prior to
any such change, shall likewise be made. Any such adjustment in outstanding
options shall be made without change in the aggregate purchase price applicable
to the unexercised portion of the option, but with a corresponding adjustment in
the price for each share of Common Stock or other unit of any security covered
by the option.

        (b) Upon the effective date of the dissolution or liquidation of the
Company, or of a reorganization, merger, combination or consolidation of the
Company with one or more other corporations in which the Company is not the
surviving corporation, or of the transfer of substantially all of the assets or
stock of the Company to another corporation, the Plan and any option theretofore
granted hereunder shall terminate unless provision is made in writing in
connection with that transaction for the continuance of the Plan and for the
assumption of options theretofore granted hereunder, or the substitution for
those options of new options covering the stock of the successor corporation, or
a parent or subsidiary thereof, with appropriate adjustments, as determined or
approved by the Plan Administrators, as to the number and kind of shares of
stock subject to the substituted options and Exercise Price with respect
thereto, in which event the Plan and the options theretofore granted, or the new
options substituted therefor, shall continue in the manner and under the terms
so provided. For the purposes of the preceding sentence, the excess of the
aggregate fair market value of the shares subject to the option immediately
after the substitution or assumption over the aggregate Exercise Price with
respect thereto shall not be more than the excess of the aggregate fair market
value of the shares subject to the option immediately before the substitution or
assumption over the aggregate Exercise Price with respect thereto, and the new
option or assumption of the old option shall not give the optionee additional
benefits which the optionee did not have under the old option.

In the event of such dissolution, liquidation, reorganization, merger,
combination, consolidation or sale or transfer of assets or stock (i) in which
provision is not made in

                                       6
<PAGE>

the transaction for the continuance of the Plan and for the assumption of
options theretofore granted or the substitution for those options of new options
covering the securities of a successor corporation or a parent or subsidiary
thereof or (ii) a difference between the excess of the aggregate fair market
value of the shares subject to the option immediately after the substitution or
assumption over the aggregate Exercise Price with respect thereto and the excess
of the aggregate fair market value of the shares subject to the option
immediately before the substitution or assumption over the aggregate Exercise
Price with respect thereto, each optionee (or that person's estate or a person
who acquired the right to exercise the option from the optionee by bequest or
inheritance) shall be entitled, prior to the effective date of the consummation
of any such transaction, to purchase, in whole or in part, the full number of
shares of Common Stock under the option or options granted to him or her which
he or she would otherwise have been entitled to purchase during the remaining
term of the option and without regard to any otherwise applicable exercise
restrictions or vesting schedules set forth in the option agreement. To the
extent that any such exercise relates to stock that is not otherwise available
for purchase through the exercise of the option by the optionee at that time,
the exercise shall be contingent upon the consummation of that dissolution,
liquidation, reorganization, merger, combination, consolidation, or sale or
transfer of assets or stock.

        Section 13.01. Termination and Amendment of Plan. The Plan shall
terminate 10 years after the earlier of its adoption by the Board of Directors
or its approval by the stockholders of the Company, and no options shall be
granted under the Plan after that date; provided, however, that termination of
the Plan shall not terminate any option granted prior thereto, and options
granted prior to termination of the Plan and existing at the time of termination
of the Plan shall continue to be subject to all the terms and conditions of the
Plan as if the Plan had not terminated. Subject to the limitation contained in
Section 14.02, the Plan Administrators may at any time amend or revise the terms
of the Plan (including the form and substance of the option agreements to be
used hereunder), provided that no amendment or revision shall (i) increase the
maximum aggregate number of share of Common Stock provided for in Section 3.01
that may be sold pursuant to options granted under the Plan, except with the
approval of the stockholders of the Company or except as required under the
provisions of Section 12.01(a), (ii) permit the granting of an option to anyone
other than as provided in Section 4.01, (iii) increase the maximum term provided
for in Sections 5.02 and 5.04 of any option, or (iv) reduce the Exercise Price
shares of Common Stock under Sections 5.03 and 5.04.

        Section 14.01. Approval of Stockholders. Within 12 months before or
after its adoption by the board of directors of the Company, as provided by
Section 5.01, the Plan must be approved by stockholders of the Company holding
at least a majority of the voting stock of the Company voting in person or by
proxy at a duly held stockholder's meeting. Options may be granted under the
Plan prior to obtaining approval, subject to the limitations of Section 13.01
concerning the period during which options may be

                                       7
<PAGE>

granted, but those options shall be contingent upon approval being obtained and
may not be exercised prior to the receipt of that approval.

        Section 14.02. Prior Rights and Obligations. No amendment, suspension or
termination of the Plan shall, without the consent of the optionee, alter or
impair any of that optionee's rights or obligations under any option granted
under the Plan prior to that amendment, suspension or termination.

        Section 15.01. Reservation of Shares of Common Stock. The Company,
during the term of the Plan, will at all times reserve and keep available a
sufficient number of shares of Common Stock to satisfy the requirements of the
Plan. In addition, the Company will from time to time, as is necessary to
accomplish the purposes of the Plan, seek to obtain from any regulatory agency
having jurisdiction any requisite authority in order to grant options under the
Plan and to issue and sell shares of Common Stock hereunder. The inability of
the Company to obtain from any regulatory agency having jurisdiction the
authority deemed by the Company's counsel to be necessary to the lawful issuance
and sale of Common Stock hereunder shall relieve the Company of any liability in
respect of the non-issuance or sale of the Common Stock as to which the
requisite authority shall not have been obtained.

        Section 16.01 Headings. The headings of the sections of the Plan are for
convenience only and shall not be considered or referred to in resolving
questions of interpretation.

        Section 17.01. Brokers' Commissions. No commission may be paid to
brokers on the sale by the Company to the optionee of Common Stock that is
optioned and sold under the Plan.

        Section 18.01. Adoption. The Plan has been adopted by a resolution duly
adopted by the board of directors of the Company.

        Section 19.01. Applicable Law. The Plan and Options granted hereunder
shall be governed by the laws of the State of Delaware, without regard to
principles of conflicts of law.
