capitalized terms used herein without definition having the respective
meanings specified in the Basic Agreement) which may be issued thereunder,
has heretofore been executed and delivered;

            WHEREAS, the Company obtained commitments from AVSA for the

            WHEREAS, the Company intends to finance the acquisition of each

            WHEREAS, in the case of each Leased Aircraft, each Owner

            WHEREAS, in the case of each Owned Aircraft, the Company will

Trust created hereby. The Applicable Certificates shall be the only
instruments evidencing a fractional undivided interest in the Applicable
Trust.

            The terms and conditions applicable to the Applicable
Certificates are as follows:

            (a) The aggregate principal amount of the Applicable
      Certificates that shall be authenticated under the Agreement (except

            (b) The Regular Distribution Dates with respect to any payment
      of Scheduled Payments means February 20 and August 20 of each year,

            (d) At the Escrow Agent's request under the Escrow Agreement,
      the Trustee shall affix the corresponding Escrow Receipt to each
      Applicable Certificate. In any event, any transfer or exchange of any
      Applicable Certificate shall also effect a transfer or exchange of
      the related Escrow Receipt. Prior to the Final Withdrawal Date, no
      transfer or exchange of any Applicable Certificate shall be permitted
      unless the corresponding Escrow Receipt is attached thereto and also
      is so transferred or exchanged. By acceptance of any Applicable
      Certificate to which an Escrow Receipt is attached, each Holder of
      such an Applicable Certificate acknowledges and accepts the
      restrictions on transfer of the Escrow Receipt set forth herein and
      in the Escrow Agreement.

            (e) (i) The Applicable Certificates shall be in the form
      attached hereto as Exhibit A. Any Person acquiring or accepting an
      Applicable Certificate or an interest therein will, by such
      acquisition or acceptance, be deemed to represent and warrant that

      of the Employee Retirement Income Security Act of 1974, as amended
      ("ERISA"), or of a plan subject to Section 4975 of the Internal
      Revenue Code of 1986, as amended (the "Code"), have not been used to
      purchase Applicable Certificates or an interest therein or (ii) the
      purchase and holding of Applicable Certificates is exempt from the
      prohibited transaction restrictions of ERISA and the Code pursuant to
      one or more prohibited transaction statutory or administrative
      exemptions.

            (ii) The Applicable Certificates shall be Book-Entry
      Certificates and shall be subject to the conditions set forth in the
      Letter of Representations between the Company and the Clearing Agency
      attached hereto as Exhibit B.

            (f)   The Applicable Certificates are subject to the Intercreditor
      Agreement, the Deposit Agreement and the Escrow Agreement.

            (g)   The Applicable Certificates will have the benefit of the
      Liquidity Facility and the Policy.

            (h)   The Responsible Party is the Company.

            Applicable Certificates pursuant to this Section 4.01(a); and

            (ii) whether or not any Class C Certificates have been issued
            and whether or not any Class C Certificateholder exercises its
            right to purchase pursuant to clause (a)(i) above, the Policy
            Provider, if it is then the Controlling Party and 180 days have

without premium, but including any other amounts then due and payable to
the Applicable Certificateholders under this Agreement, the Intercreditor

the Applicable Certificates; provided, however, that (i) if such purchase
occurs after the record date specified in Section 2.03(b) of the Escrow
Agreement relating to the distribution of unused Deposits and accrued and
unpaid interest thereunder, such purchase price shall be reduced by the
aggregate amount of unused Deposits and interest to be distributed under
the Escrow Agreement (which deducted amounts shall remain distributable to,
and may be retained by, the Applicable Certificateholder as of such Record
Date) and (ii) if such purchase occurs after a Record Date, such purchase
price shall be reduced by the amount to be distributed hereunder on the
related Distribution Date (which deducted amounts shall remain
distributable to, and may be retained by, the Applicable Certificateholder
as of such Record Date); provided further that no such purchase of
Applicable Certificates shall be effective unless the purchaser(s) shall
certify to the Trustee that contemporaneously with such purchase, such
purchaser(s) is purchasing the Applicable Certificates pursuant to the
terms of this Agreement and the trust supplement entered into with respect
to the Class C Trust (if any). Each payment of the purchase price of the

obligation of such Applicable Certificateholder in this Agreement, the
Escrow Agreement, the Deposit Agreement, the Intercreditor Agreement, the
Liquidity Facility, the Policy, the Note Documents and all Applicable

(excluding all right, title and interest under any of the foregoing to the
extent such right, title or interest is with respect to an obligation not
then due and payable as respects any action or inaction or state of affairs
occurring prior to such sale) and the purchaser shall assume all of such
Applicable Certificateholder's obligations under this Agreement, the Escrow
Agreement, the Deposit Agreement, the Intercreditor Agreement, the
Liquidity Facility, the Policy, the Note Documents and all such Applicable
Certificates and Escrow Receipts. The Applicable Certificates will be
deemed to be purchased on the date payment of the purchase price is made
notwithstanding the failure of the Applicable Certificateholders to deliver

of the Applicable Certificateholders will be to deliver the Applicable
Certificates to the purchaser(s) and receive the purchase price for such
Applicable Certificates and (ii) if the purchaser(s) shall so request, such
Applicable Certificateholder will comply with all the provisions of Section

Trustee is hereby directed (i) to execute and deliver the Intercreditor
Agreement, the Escrow Agreement and the Note Purchase Agreement, each in
the form delivered to the Trustee by the Company and (ii) subject to the

request of the Company and the satisfaction or waiver of the closing
conditions specified in the Underwriting Agreement, the Trustee shall
execute, deliver, authenticate, issue and sell Applicable Certificates in
authorized denominations equaling in the aggregate the amount set forth,
with respect to the Applicable Trust, in Schedule I to the Underwriting
Agreement evidencing the entire ownership interest in the Applicable Trust,
which amount equals the maximum aggregate principal amount of Equipment
Notes which may be purchased by the Trustee pursuant to the Note Purchase
Agreement. Except as provided in Sections 3.03, 3.04, 3.05 and 3.06 of the
Basic Agreement, the Trustee shall not execute, authenticate or deliver
Applicable Certificates in excess of the aggregate amount specified in this
paragraph.

            (b) On or after the Issuance Date the Company may deliver from
time to time to the Trustee a Closing Notice relating to one or more
Equipment Notes. After receipt of a Closing Notice and in any case no later
than one Business Day prior to a Delivery Date as to which such Closing
Notice relates (the "Applicable Delivery Date"), the Trustee shall (as and
when specified in the Closing Notice) instruct the Escrow Agent to provide
a Notice of Purchase Withdrawal to the Depositary requesting (A) the
withdrawal of one or more Deposits on the Applicable Delivery Date in
accordance with and to the extent permitted by the terms of the Escrow
Agreement and the Deposit Agreement and (B) the payment of all, or a
portion, of such Deposit or Deposits in an amount equal in the aggregate to
the purchase price of such Equipment Notes to or on behalf of the Owner
Trustee or the Company, as the case may be, issuing such Equipment Notes,

when specified in such Closing Notice), subject to the conditions set forth

obligations under the Participation Agreement specified in such Closing
Notice (the "Applicable Participation Agreement") and cause such
certificates, documents and legal opinions relating to the Trustee to be
duly delivered as required by the Applicable Participation Agreement. If at
any time prior to the Applicable Delivery Date, the Trustee receives a
notice of postponement pursuant to Section 2(e), 2(f), or 2(g) of the Note
Purchase Agreement, then the Trustee shall give the Depositary (with a copy
to the Escrow Agent) a notice of cancellation of such Notice of Purchase
Withdrawal relating to such Deposit or Deposits on such Applicable Delivery
Date. Upon satisfaction of the conditions specified in the Note Purchase
Agreement and the Applicable Participation Agreement, the Trustee shall
purchase the applicable Equipment Notes with the proceeds of the
withdrawals of one or more Deposits made on the Applicable Delivery Date in
accordance with the terms of the Deposit Agreement and the Escrow
Agreement. The purchase price of such Equipment Notes shall equal the
principal amount of such Equipment Notes. Amounts withdrawn from such

or to the extent not applied on the Applicable Delivery Date to the

the Depositary substantially in the form of Exhibit B to the Deposit
Agreement (the "Final Withdrawal Notice") and (ii) the Trustee will make a
demand upon the Company under the Note Purchase Agreement for an amount
equal to the Special Redemption Premium, such payment to be made on the
Final Withdrawal Date.

            Section 5.03The Trustee. (a) Subject to Section 5.04 of this
Trust Supplement and Section 7.15 of the Basic Agreement, the Trustee shall
not be responsible in any manner whatsoever for or in respect of the

the Escrow Agreement or the due execution hereof or thereof by the Company
or the other parties thereto (other than the Trustee), or for or in respect
of the recitals and statements contained herein or therein, all of which
recitals and statements are made solely by the Company.

            (b) Except as herein otherwise provided, no duties,
responsibilities or liabilities are assumed, or shall be construed to be
assumed by the Trustee by reason of this Trust Supplement other than as set
forth in the Basic Agreement, and this Trust Supplement is executed and
accepted on behalf of the Trustee, subject to all the terms and conditions
set forth in the Basic Agreement, upon the effectiveness thereof, as fully
to all intents as if the same were herein set forth at length.

            Section 5.04. Representations and Warranties of the Trustee.

(i) applicable bankruptcy, insolvency, reorganization, moratorium or
similar laws affecting the rights of creditors generally and (ii) general
principles of equity.

            Section 5.05. Trustee Liens. The Trustee in its individual
capacity agrees, in addition to the agreements contained in Section 7.17 of
the Basic Agreement, that it will at its own cost and expense promptly take
any action as may be necessary to duly discharge and satisfy in full any
Trustee's Liens on or with respect to the Trust Property which is
attributable to the Trustee in its individual capacity and which is
unrelated to the transactions contemplated by the Intercreditor Agreement
or the Note Purchase Agreement.

from time to time, enter into one or more agreements supplemental to the
Escrow Agreement, the Note Purchase Agreement, the Policy Provider
Agreement or the Deposit Agreement, for any of the purposes set forth in
clauses (1) through (9) of such Section 9.01, except that (a) clause (3) of

powers conferred by the Note Purchase Agreement and (b) clause (4) of such
Section 9.01 shall be deemed to include corrections or supplements to
provisions of the Escrow Agreement or the Deposit Agreement which may be
defective or inconsistent with any other provision of this Agreement or
contained in any agreement referred to in such clause (4) and the curing of
any ambiguity or the modification of any other provision with respect to
matters or questions arising under the Escrow Agreement or the Deposit
Agreement.

            Section 6.02. Supplemental Agreements with Consent of
Applicable Certificateholders. The provisions of Section 9.02 of the Basic
Agreement shall apply to agreements or amendments for the purpose of adding
any provisions to or changing in any manner or eliminating any of the

Policy Provider Agreement or the Note Purchase Agreement; provided that the
provisions of Section 9.02(1) of the Basic Agreement shall be deemed to

            Section 9.02 shall also be amended to strike the second

                                 ARTICLE VII
                             TERMINATION OF TRUST

            Section 7.01. Termination of the Trust. The respective
obligations and responsibilities of the Company and the Trustee with
respect to the Applicable Trust shall terminate upon the distribution to
all Applicable Certificateholders and the Trustee of all amounts required
to be distributed to them pursuant to this Agreement and the disposition of
all property held as part of the Trust Property; provided, however, that in
no event shall the Applicable Trust continue beyond 21 years less one day
following the death of the last survivor of all descendants living on the
date hereof of Joseph P. Kennedy, Sr., unless applicable law shall permit a
longer term, in which case such longer term shall apply.

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

            In the event that all of the Applicable Certificateholders
shall not surrender their Applicable Certificates for cancellation within
six months after the date specified in the above-mentioned written notice,
the Trustee shall give a second written notice to the remaining Applicable
Certificateholders to surrender their Applicable Certificates for
cancellation and receive the final distribution with respect thereto. No
additional interest shall accrue on the Applicable Certificates after the
Distribution Date specified in the first written notice. In the event that
any money held by the Trustee for the payment of distributions on the
Applicable Certificates shall remain unclaimed for two years (or such
lesser time as the Trustee shall be satisfied, after sixty days' notice
from the Company, is one month prior to the escheat period provided under
applicable law) after the final distribution date with respect thereto, the
Trustee shall pay to each Loan Trustee the appropriate amount of money
relating to such Loan Trustee and shall give written notice thereof to the
related Owner Trustees, the Owner Participants and the Company.


                                ARTICLE VIII
                                THE COMPANY

            Section 8.01. Consolidation, Mergers, Etc. Section 5.02 of the
Basic Agreement is hereby amended with respect to the Applicable Trust by
deleting the word "and" at the end of clause (b) thereof, renumbering
clause (c) as clause "(d)" and inserting a new clause (c) as follows:

            "(c) immediately after giving effect to such transaction, no
      Indenture Event of Default (in the case of an Owned Aircraft) or, in
      the case of a Leased Aircraft, Lease Event of Default (as defined in
      the related Indenture) shall have occurred and be continuing; and"


                                 ARTICLE IX
                          MISCELLANEOUS PROVISIONS

            Section 9.01. Basic Agreement Ratified. Except and so far as
herein expressly provided, all of the provisions, terms and conditions of
the Basic Agreement are in all respects ratified and confirmed; and the
Basic Agreement and this Trust Supplement shall be taken, read and
construed as one and the same instrument.

            Section 9.02. GOVERNING LAW. THIS AGREEMENT AND THE APPLICABLE
CERTIFICATES SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS
OF THE STATE OF NEW YORK.

            Section 9.03. Execution in Counterparts. This Trust Supplement
may be executed in any number of counterparts, each of which shall be an
original, but such counterparts shall together constitute but one and the
same instrument.

            Section 9.04. Intention of Parties. The parties hereto intend
that the Applicable Trust be classified for U.S. federal income tax
purposes as a grantor trust under Subpart E, Part I of Subchapter J of the
Internal Revenue Code of 1986, as amended, and not as a trust or
association taxable as a corporation or as a partnership. Each Applicable
Certificateholder and Investor, by its acceptance of its Applicable
Certificate or a beneficial interest therein, agrees to treat the
Applicable Trust as a grantor trust for all U.S. federal, state and local
income tax purposes. The powers granted and obligations undertaken pursuant
to the Agreement shall be so construed so as to further such intent.

            Section 9.05. Third Party Beneficiary. For purposes of
enforcement, the Policy Provider shall be an express third party
beneficiary of this Agreement.

            Section 9.06. Benefits of Agreement. (a) Nothing in this
Agreement or in the Certificates of any series, express or implied, shall
give to any person, other than the parties hereto and their successors
hereunder, the Certificateholders of each series and the Policy Provider
(as third party beneficiary), any benefit or any legal or equitable right,
remedy or claim under this Agreement.

            (b) This Section 9.06 supercedes and replaces Section 12.10 of
the Basic Agreement.


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

*This legend to appear on Book-Entry Certificates to be deposited with The
Depository Trust Company.


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

            Subject to and in accordance with the terms of the Agreement
and any related Intercreditor Agreement, from funds then available to the
Trustee, there will be distributed on each February 20 and August 20 (a
"Regular Distribution Date"), commencing on February 20, 2001, to the
Person in whose name this Certificate is registered at the close of
business on the 15th day preceding the Regular Distribution Date, an amount
in respect of the Scheduled Payments on the Equipment Notes due on such
Regular Distribution Date, the receipt of which has been confirmed by the
Trustee, equal to the product of the percentage interest in the Trust
evidenced by this Certificate and an amount equal to the sum of such
Scheduled Payments. Subject to and in accordance with the terms of the
Agreement and any related Intercreditor Agreement, in the event that
Special Payments on the Equipment Notes are received by the Trustee, from
funds then available to the Trustee, there shall be distributed on the
applicable Special Distribution Date, to the Person in whose name this
Certificate is registered at the close of business on the 15th day
preceding the Special Distribution Date, an amount in respect of such
Special Payments on the Equipment Notes, the receipt of which has been
confirmed by the Trustee, equal to the product of the percentage interest
in the Trust evidenced by this Certificate and an amount equal to the sum
of such Special Payments so received. If a Regular Distribution Date or
Special Distribution Date is not a Business Day, distribution shall be made
on the immediately following Business Day with the same force and effect as
if made on such Regular Distribution Date or Special Distribution Date and
no interest shall accrue during the intervening period. The Trustee shall
mail notice of each Special Payment and the Special Distribution Date
therefor to the Certificateholder of this Certificate.

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

            The Certificates do not represent a direct obligation of, or an
obligation guaranteed by, or an interest in, the Company or the Trustee or
any affiliate thereof. The Certificates are limited in right of payment,
all as more specifically set forth on the face hereof and in the Agreement.
All payments or distributions made to Certificateholders under the
Agreement shall be made only from the Trust Property and only to the extent
that the Trustee shall have sufficient income or proceeds from the Trust
Property to make such payments in accordance with the terms of the
Agreement. Each Certificateholder of this Certificate, by its acceptance
hereof, agrees that it will look solely to the income and proceeds from the
Trust Property to the extent available for distribution to such
Certificateholder as provided in the Agreement. This Certificate does not
purport to summarize the Agreement and reference is made to the Agreement
for information with respect to the interests, rights, benefits,
obligations, proceeds, and duties evidenced hereby. A copy of the Agreement
may be examined during normal business hours at the principal office of the
Trustee, and at such other places, if any, designated by the Trustee, by
any Certificateholder upon request.

            The Agreement permits, with certain exceptions therein
provided, the amendment thereof and the modification of the rights and
obligations of the Company and the rights of the Certificateholders under
the Agreement at any time by the Company and the Trustee with the consent
of the Certificateholders holding Certificates evidencing Fractional
Undivided Interests aggregating not less than a majority in interest in the
Trust. Any such consent by the Certificateholder of this Certificate shall
be conclusive and binding on such Certificateholder and upon all future
Certificateholders of this Certificate and of any Certificate issued upon
the transfer hereof or in exchange hereof or in lieu hereof whether or not
notation of such consent is made upon this Certificate. The Agreement also
permits the amendment thereof, in certain limited circumstances, without
the consent of the Certificateholders of any of the Certificates.

            As provided in the Agreement and subject to certain limitations
set forth, the transfer of this Certificate is registrable in the Register
upon surrender of this Certificate for registration of transfer at the
offices or agencies maintained by the Trustee in its capacity as Registrar,
or by any successor Registrar duly endorsed or accompanied by a written
instrument of transfer in form satisfactory to the Trustee and the
Registrar, duly executed by the Certificateholder hereof or such
Certificateholder's attorney duly authorized in writing, and thereupon one
or more new Certificates of authorized denominations evidencing the same
aggregate Fractional Undivided Interest in the Trust will be issued to the
designated transferee or transferees.

            The Certificates are issuable only as registered Certificates
without coupons in minimum denominations of $1,000 Fractional Undivided
Interest and integral multiples thereof except that one Certificate may be
issued in a different denomination. As provided in the Agreement and
subject to certain limitations therein set forth, the Certificates are
exchangeable for new Certificates of authorized denominations evidencing
the same aggregate Fractional Undivided Interest in the Trust, as requested
by the Certificateholder surrendering the same.

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

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

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

            The obligations and responsibilities created by the Agreement
and the Trust created thereby shall terminate upon the distribution to
Certificateholders of all amounts required to be distributed to them
pursuant to the Agreement and the disposition of all property held as part
of the Trust Property.

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

            THE AGREEMENT AND THIS CERTIFICATE SHALL BE GOVERNED BY AND
CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK AND THE
OBLIGATIONS, RIGHTS AND REMEDIES OF THE PARTIES HEREUNDER SHALL BE
DETERMINED IN ACCORDANCE WITH SUCH LAWS.

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

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

Final Legal Distribution Date, any shortfall in amounts available to the
Subordination Agent (or, in the case of Escrow Receipts, the Paying Agent
(as defined in the Escrow and Paying Agent Agreement for the Class G

Agreement and to the application of any amounts available to the Escrow
Agent in the Class G Paying Agent Account in respect of accrued interest at
the Stated Interest Rate on the Class G Deposits, any drawing paid under
the Class G Liquidity Facility in respect of interest due on the Class G

for the payment of accrued and unpaid interest on the Class G Certificates
and, without duplication, accrued and unpaid interest on any Deposit

and Paying Agent Agreement for the Class G Trust), in each case at the
Stated Interest Rate for the Class G Certificates on the Pool Balance of
the Class G Certificates on such Distribution Date;

         (ii) with respect to any Special Distribution Date (other than an
Election Distribution Date or a Special Distribution Date established
pursuant to the succeeding clause (iv) below) established by reason of
receipt of a Special Payment constituting the proceeds of any Series G
Equipment Notes (as to which there has been a default in the payment of
principal thereof or that has been accelerated) or the related Trust
Indenture Estate or Indenture Estate, as the case may be, any shortfall in
the amounts available to the Subordination Agent after giving effect to the
subordination provisions of the Agreement and to the application of any
amounts available to the Escrow Agent in the Class G Paying Agent Account

under the Class G Liquidity Facility in respect of interest due on the
Class G Certificates on such Distribution Date and any withdrawal from the
Class G Cash Collateral Account in respect of interest due on such
Distribution Date in accordance with the Agreement, required to reduce the
Pool Balance of the Class G Certificates by an amount equal to the
outstanding principal amount of such Series G Equipment Note (determined
immediately prior to the receipt of such proceeds) plus accrued and unpaid
interest on the amount of such reduction at the Stated Interest Rate for
the Class G Certificates from the period from the immediately preceding
Regular Distribution Date to such Special Distribution Date;

         (iii) with respect to the Special Distribution Date established by
reason of the failure of the Subordination Agent to have received a Special
Payment constituting the proceeds of any Series G Equipment Note or the
related Trust Indenture Estate or Indenture Estate, as the case may be,
during the eighteen (18) month period beginning on the last date on which
full payment was made on such Series G Equipment Note (the date of such
payment in full, the "Last Payment Date") as to which there has been a
failure to pay principal or that has been accelerated subsequent to the
Last Payment Date, the amount equal to the outstanding principal amount of
such Series G Equipment Note plus accrued and unpaid interest thereon at
the Stated Interest Rate for the Class G Certificates from the immediately
preceding Regular Distribution Date to such Special Distribution Date;
provided, however, if MBIA shall have duly given a Policy Provider Election
(as defined below) with respect to such Series G Equipment Note at the end
of such eighteen (18) month period and at least five (5) days prior to such
Special Distribution Date, the Deficiency Amount shall be an amount equal
to (A) with respect to such Special Distribution Date the scheduled
principal and interest payable but not paid on such Series G Equipment Note
(without regard to the acceleration thereof) during such eighteen (18)
month period (after giving effect to the application of any drawing paid
under the Class G Liquidity Facility and any withdrawal from the Class G
Cash Collateral Account attributable to such interest on such Series G
Equipment Note) and (B) thereafter, on each Regular Distribution Date
following such Special Distribution Date as to which a Policy Provider
Election has been given in respect of such Series G Equipment Note, and
prior to the establishment of an Election Distribution Date or a Special
Distribution Date pursuant to the immediately succeeding clause (iv) with
respect to such Series G Equipment Note, an amount equal to the scheduled
principal (without regard to the acceleration thereof) and interest payable
on such Series G Equipment Note on the related payment date;

         (iv) following the giving of any Policy Provider Election, with
respect to any Business Day elected by MBIA upon twenty (20) days prior
notice (which shall be a Special Distribution Date) and upon request by
MBIA to the Subordination Agent to make a drawing under this Policy, an
amount equal to the then outstanding principal balance of the Series G
Equipment Note as to which the Policy Provider Election was given (less any
drawings previously paid by MBIA in respect of principal on such Series G
Equipment Note) and accrued and unpaid interest thereon at the Stated
Interest Rate for the Class G Certificates from the immediately preceding
Regular Distribution Date to such Special Distribution Date;

         (v) with respect to any Special Distribution Date which is an
Election Distribution Date, an amount equal to the then outstanding
principal balance of the Series G Equipment Note as to which such Election
Distribution Date relates (less any drawing previously paid by MBIA in
respect of principal of such Series G Equipment Note) and accrued and
unpaid interest thereon at the Stated Interest Rate for the Class G
Certificates from the immediately preceding Regular Distribution Date to
such Election Distribution Date; and

         (vi) with respect to the Final Legal Distribution Date, any
shortfall in amounts available to the Subordination Agent after giving
effect to the subordination provisions of the Agreement and to the
application of any amounts available to the Escrow Agent in the Class G
Paying Agent Account in respect of accrued interest on the Class G
Deposits, any drawing paid under the Class G Liquidity Facility in respect
of interest included in the Final Distribution and any withdrawal from the
Class G Cash Collateral Account in respect of interest included in the
Final Distribution in accordance with the Agreement, for the payment in
full of the Final Distribution (calculated as of such date but excluding
any accrued and unpaid premium) on the Class G Certificates.

         For the avoidance of doubt, no Deficiency Amount described in
clauses (i)-(vi) above or payment to be made in respect of an Avoided
Payment described below shall constitute an accelerated or acceleration
payment.

         If any amount paid or required to be paid in respect of the Class
G Certificates made to a Class G Certificateholder is voided (an "Avoidance
Event") under any applicable bankruptcy, insolvency, receivership or
similar law in an Insolvency Proceeding, and, as a result of such an
Avoidance Event, the Beneficiary, the Class G Trustee or any Class G
Certificateholder is required to return such voided payment, or any portion
of such voided payment made or to be made in respect of the Class G
Certificates (including any disgorgement from the Class G
Certificateholders resulting from any such Insolvency Proceeding, whether
such disgorgement is determined on a theory of preferential conveyance or
otherwise) (an "Avoided Payment"), MBIA will pay an amount equal to each
such Avoided Payment, irrevocably, absolutely and unconditionally and
without the assertion of any defenses to payment, including fraud in
inducement or fact or any other circumstances that would have the effect of
discharging a surety in law or in equity, upon receipt by MBIA from the
Beneficiary, the Class G Trustee or such Class G Certificateholder of (x) a
certified copy of a final (nonappealable) order of a court exercising
jurisdiction in such Insolvency Proceeding to the effect that the
Beneficiary, the Class G Trustee or such Class G Certificateholder is
required to return any such payment or portion thereof because such payment
was voided under applicable law, with respect to which order the appeal
period has expired without an appeal having been filed (the "Final Order"),
(y) an assignment, in the form of Exhibit D hereto, irrevocably assigning
to MBIA all rights and claims of such Beneficiary, Class G Trustee or Class
G Certificateholder relating to or arising under such Avoided Payment and
(z) a Notice of Avoided Payment in the form of Exhibit B hereto
appropriately completed and executed by the Beneficiary, Class G Trustee or
such Class G Certificateholder. Such payment shall be disbursed to the
receiver, conservator, debtor-in-possession or trustee in bankruptcy named
in the Final Order and not to the Beneficiary, Class G Trustee or such
Class G Certificateholder directly unless such Class G Certificateholder,
the Class G Trustee or the Beneficiary has returned such payment to such
receiver, conservator, debtor-in-possession or trustee in bankruptcy, in
which case such payment shall be disbursed to such Class G
Certificateholder, the Class G Trustee or the Beneficiary, as the case may
be.

         Notwithstanding the foregoing, in no event shall MBIA be obligated
to make any payment in respect of any Avoided Payment, which payment
represents a payment of the principal amount of the Class G Certificates,
prior to the time MBIA would have been required to make a payment in
respect of such principal pursuant to sub-paragraphs (ii-vi) of this
Policy; provided, further, that no payment of principal under this Policy
on any Distribution Date, other than with respect to an Avoided Payment,
shall exceed the Net Principal Policy Amount (as defined below) for such
Distribution Date; provided, further, that no payment, other than with
respect to an Avoided Payment, of a Deficiency Amount shall be in excess of
the then outstanding Pool Balance of the Class G Certificates and accrued
and unpaid interest thereon at the Stated Interest Rate on the Class G
Certificates. This Policy does not cover (i) any premium, prepayment
penalty or other accelerated payment, which at any time may become due on
or with respect to any Class G Certificate, (ii) shortfalls, if any,
attributable to the liability of the Subordination Agent, the Paying Agent,
the Class G Trust or the Class G Trustee for withholding taxes, if any
(including interest and penalties in respect of any such liability), or
(iii) any failure of the Escrow Agent, the Subordination Agent or the Class
G Trustee to make any payment due to the Class G Certificateholders or, if
applicable, the Escrow Receiptholders from funds received.

the extent of any payment hereunder.

         This Policy is neither transferable nor assignable, in whole or in
part, except to a successor Subordination Agent duly appointed and
qualified under the Agreement. Such transfer and assignment shall be
effective upon receipt by MBIA of a copy of the instrument effecting such
transfer and assignment signed by the transferor and by the transferee, and
a certificate, properly completed and signed by the transferor and the
transferee, in the form of Exhibit C hereto (which shall be conclusive

and shall not be modified, altered or affected by any other agreement or
instrument, including any modification or amendment to any other agreement

Airways, Inc. or any other Person and may not be canceled or revoked by
MBIA prior to the time it is terminated in accordance with the express
terms hereof. The Premium on this Policy is not refundable for any reason.

         This Policy shall be returned to MBIA upon termination.

         THIS POLICY SHALL BE CONSTRUED, AND THE OBLIGATIONS, RIGHTS AND
REMEDIES OF THE PARTIES HEREUNDER SHALL BE DETERMINED, IN ACCORDANCE WITH
THE LAWS OF THE STATE OF NEW YORK, WITHOUT REGARD TO CONFLICT OF LAWS
PRINCIPLES OR THE APPLICATION OF THE LAWS OF ANY OTHER JURISDICTION.


         IN WITNESS WHEREOF, MBIA has caused this Policy to be duly
executed on the date first written above.

Illinois, Pittsburgh, Pennsylvania, Hartford, Connecticut or Salt Lake
City, Utah.

            The Depositary reserves the right, upon at least 14 days' prior
written notice to US Airways, the Escrow Agent and the Pass Through
Trustee, to require seven days' notice for any withdrawal.

            (b) (i) The Escrow Agent may, by providing at least fifteen
(15) days' prior notice of withdrawal to the Depositary substantially in
the form of Exhibit B hereto (a "Notice of Final Withdrawal"), withdraw the
entire amount of all of the remaining Deposits together with the payment by
the Depositary of all accrued and unpaid interest on such Deposits to but
excluding the specified date of withdrawal (a "Final Withdrawal"), on such
date as shall be specified in such Notice of Final Withdrawal. If a Notice
of Final Withdrawal has not been given to the Depositary on or before
February 8, 2001 (or June 8, 2001 if all the Equipment Notes under the Note
Purchase Agreement have not been purchased by February 7, 2001 on account
of manufacturing delays that occur for reasons beyond the control of US
Airways and that are not occasioned by US Airways' fault or negligence) and
there are unwithdrawn Deposits on such date, the Depositary shall pay the
amount of the Final Withdrawal to the Paying Agent on February 23, 2001 (or
June 25, 2001 if all the Equipment Notes under the Note Purchase Agreement
have not been purchased by February 7, 2001 on account of manufacturing
delays that occur for reasons beyond the control of US Airways and that are
not occasioned by US Airways' fault or negligence).

            (ii) The Escrow Agent may, by providing at least 15 days' prior
notice of withdrawal to the Depositary in the form of Exhibit C hereto (a
"Notice of Replacement Withdrawal"), request withdrawal of the entire
amount of all Deposits then held by the Depositary together with, if
specified in such Notice of Replacement Withdrawal, the payment by the
Depositary of all accrued and unpaid interest on such Deposits to but
excluding the specified date of withdrawal (a "Replacement Withdrawal"), on
such date as shall be specified in such Notice of Replacement Withdrawal.

            (c) If the Depositary receives a duly completed Notice of
Purchase Withdrawal or Notice of Final Withdrawal or Notice of Replacement
Withdrawal (each a "Withdrawal Notice") complying on its face with the
provisions of this Agreement, it shall make the payments specified therein
in accordance with the provisions of this Agreement.

            If such complying Withdrawal Notice is received by the
Depositary no later than 3:00 p.m. on a Business Day, the Depositary shall
make the payments requested in such Withdrawal Notice no later than 11:00
a.m. on the next succeeding Business Day or such later day specified in
such Withdrawal Notice, and if such complying Withdrawal Notice is received
by the Depositary after 3:00 p.m. on a Business Day, the Depositary shall
make the payments requested in such Withdrawal Notice no later than 11:00
a.m. on the second Business Day next following such Business Day.

            Section 2.4 Other Accounts.

            On the date of withdrawal of any Deposit pursuant to a Notice
of Purchase Withdrawal, the Escrow Agent, or the Pass Through Trustee on
behalf of the Escrow Agent, shall be entitled to re-deposit with the
Depositary any portion thereof and the Depositary shall accept the same for
deposit hereunder. Any sums so received for deposit shall be established as
a new Deposit and credited to a new Account, all as more fully provided in
Section 2.1 hereof, and thereafter the provisions of this Agreement shall
apply thereto as fully and with the same force and effect as if such
Deposit had been established on the Deposit Date except that (i) such
Deposit may not be withdrawn prior to the date seven days after the
establishment thereof and (ii) such Deposit shall mature on June 25, 2001
and bear interest as provided in Section 2.2. The Depositary shall promptly
give notice to the Escrow Agent of receipt of each such re-deposit and the
account number assigned thereto.

                            ARTICLE III  TERMINATION

            (a) This Agreement shall terminate on the fifth (5th) Business
Day after the later of the date on which (i) all of the Deposits shall have
been withdrawn and paid as provided herein without any re-deposit and (ii)
all accrued and unpaid interest on the Deposits shall have been paid as
provided herein, but in no event prior to the date on which the Depositary
shall have performed in full its obligations hereunder.

            (b) For the avoidance of doubt, the obligations of the
Depositary under the last sentence of Section 2.2 hereof shall remain in
full force and effect notwithstanding the execution and delivery of a
replacement Deposit Agreement in accordance with Section 5(a)(vii) of the
Note Purchase Agreement.


                            ARTICLE IV PAYMENTS

            All payments (including, without limitation, those payments
made in respect of Taxes (as defined and provided for below)) made by the
Depositary hereunder shall be paid in United States Dollars and immediately
available funds by wire transfer (i) in the case of accrued interest on the
Deposits payable under Section 2.2 hereof or any Final Withdrawal, directly
to the Paying Agent at State Street Bank and Trust Company of Connecticut,
National Association, c/o State Street Bank and Trust Company, 2
International Place, 4th Floor, Boston, MA 02110, ABA# 011-0000-28, Account
# 9903-9901 RE: US Air EETC 2000-1 (include tail number for the related
Deposit), Attention: Sandra Thomson, Reference: US Airways 2000-1G EETC, or
to such other account as the Paying Agent may direct from time to time in
writing to the Depositary and the Escrow Agent and (ii) in the case of any
withdrawal of one or more Deposits pursuant to a Notice of Purchase
Withdrawal or all the then remaining Deposits pursuant to a Notice of
Replacement Withdrawal, directly to or as directed by the Pass Through
Trustee as specified and in the manner provided in such Notice of Purchase
Withdrawal or Notice of Replacement Withdrawal. The Depositary hereby
waives any and all rights of set-off, combination of accounts, right of
retention or similar right (whether arising under applicable law, contract
or otherwise) it may have against the Deposits howsoever arising. All
payments on or in respect of each Deposit shall be made free and clear of
and without reduction for or on account of any and all taxes, levies or
other impositions or charges (collectively, "Taxes"). However, if the
Depositary or the Paying Agent (pursuant to Section 2.4 of the Escrow and
Paying Agent Agreement) shall be required by law to deduct or withhold any
Taxes from or in respect of any sum payable hereunder, the Depositary
shall: (i) make such deductions or withholding; (ii) pay the full amount
deducted or withheld (including in respect of such additional amounts) to
the competent taxation authority; and (iii) if the Taxes required to be
deducted or withheld are imposed by The Netherlands or any political
subdivision thereof, pay such additional amounts as may be necessary in
order that the actual amount received by the designated recipient of such
sum under this Agreement or the Escrow and Paying Agent Agreement after
such deduction or withholding equals the sum it would have received had no
such deduction or withholding been required. If the date on which any
payment due on any Deposit would otherwise fall on a day which is not a
Business Day, such payment shall be made on the next succeeding Business
Day with the same force and effect as if made on such scheduled date, and
no additional interest shall accrue in respect of such extension.


                   ARTICLE V  REPRESENTATIONS AND WARRANTIES

            The Depositary hereby represents and warrants to US Airways,

and conditions hereinafter set forth, to make Advances to the Borrower from
time to time on any Business Day during the period from the Effective Date
until 1:00 p.m. (New York City time) on the Expiry Date (unless the

accordance with the terms of Section 2.04(b)) in an aggregate amount at any
time outstanding not to exceed the Maximum Commitment.

            Section 2.02  Making the Advances

            (a) Interest Advances shall be made in one or more Borrowings

this Agreement shall have been delivered to the Borrower as contemplated by
said Section 3.6(d) within the time period specified in such Section) by
delivery to the Liquidity Provider of a written and completed Notice of
Borrowing in substantially the form of Annex II attached hereto, signed by
a Responsible Officer of the Borrower, in an amount equal to the Maximum
Available Commitment at such time, and shall be used to fund the Class G
Cash Collateral Account in accordance with said Section 3.6(d) and Section
3.6(f) of the Intercreditor Agreement.

            (c) A Downgrade Advance shall be made in a single Borrowing
upon a downgrading of the Liquidity Provider's short-term unsecured debt
rating issued by either Rating Agency below the applicable Threshold Rating
(as provided for in Section 3.6(c) of the Intercreditor Agreement) unless a
Replacement Liquidity Facility to replace this Agreement shall have been
previously delivered to the Borrower in accordance with said Section 3.6(c)
and within the time period specified in such Section, by delivery to the
Liquidity Provider of a written and completed Notice of Borrowing in
substantially the form of Annex III attached hereto, signed by a
Responsible Officer of the Borrower, in an amount equal to the Maximum
Available Commitment at such time, and shall be used to fund the Class G
Cash Collateral Account in accordance with said Section 3.6(c) and Section
3.6(f) of the Intercreditor Agreement.

            (d) A Final Advance shall be made in a single Borrowing upon
the receipt by the Borrower of a Termination Notice from the Liquidity
Provider pursuant to Section 6.01 hereof by delivery to the Liquidity
Provider of a written and completed Notice of Borrowing in substantially
the form of Annex IV attached hereto, signed by a Responsible Officer of
the Borrower, in an amount equal to the Maximum Available Commitment at
such time, and shall be used to fund the Class G Cash Collateral Account in
accordance with Section 3.6(i) and Section 3.6(f) of the Intercreditor
Agreement.

            (e) Each Borrowing shall be made on notice in writing (a
"Notice of Borrowing") in substantially the form required by Section
2.02(a), 2.02(b), 2.02(c) or 2.02(d), as the case may be, given by the
Borrower to the Liquidity Provider. If a Notice of Borrowing is delivered
by the Borrower in respect of any Borrowing no later than 1:00 p.m. (New
York City time) on a Business Day, upon satisfaction of the conditions
precedent set forth in Section 4.02 with respect to a requested Borrowing,
the Liquidity Provider shall make available to the Borrower, in accordance
with its payment instructions, the amount of such Borrowing in U.S. dollars
and immediately available funds, before 4:00 p.m. (New York City time) on
such Business Day or on such later Business Day specified in such Notice of
Borrowing. If a Notice of Borrowing is delivered by the Borrower in respect
of any Borrowing after 1:00 p.m. (New York City time) on a Business Day,
upon satisfaction of the conditions precedent set forth in Section 4.02
with respect to a requested Borrowing, the Liquidity Provider shall make
available to the Borrower, in accordance with its payment instructions, the
amount of such Borrowing in U.S. dollars and in immediately available
funds, before 12:00 noon (New York City time) on the first Business Day
next following the day of receipt of such Notice of Borrowing or on such
later Business Day specified by the Borrower in such Notice of Borrowing.
Payments of proceeds of a Borrowing shall be made by wire transfer of
immediately available funds to the Borrower in accordance with such wire
transfer instructions as the Borrower shall furnish from time to time to
the Liquidity Provider for such purpose. Each Notice of Borrowing shall be
irrevocable and binding on the Borrower. Each Notice of Borrowing shall be
effective upon delivery of a copy thereof to the Liquidity Provider's New
York Branch at the address specified in Section 7.02. (f) Upon the making
of any Advance requested pursuant to a Notice of Borrowing, in accordance
with the Borrower's payment instructions, the Liquidity Provider shall be
fully discharged of its obligation hereunder with respect to such Notice of
Borrowing, and the Liquidity Provider shall not thereafter be obligated to
make any further Advances hereunder in respect of such Notice of Borrowing
to the Borrower or to any other Person. If the Liquidity Provider makes an
Advance requested pursuant to a Notice of Borrowing before 12:00 noon (New
York City time) on the second Business Day after the date of payment
specified in said Section 2.02(e), the Liquidity Provider shall have fully
discharged its obligations hereunder with respect to such Advance and an
event of default shall not have occurred hereunder. Following the making of
any Advance pursuant to Section 2.02(b), (c) or (d) hereof to fund the
Class G Cash Collateral Account, the Liquidity Provider shall have no
interest in or rights to the Class G Cash Collateral Account, such Advance
or any other amounts from time to time on deposit in the Class G Cash
Collateral Account; provided that the foregoing shall not affect or impair
the obligations of the Subordination Agent to make the distributions
contemplated by Section 3.6(e) or (f) of the Intercreditor Agreement. By
paying to the Borrower proceeds of Advances requested by the Borrower in
accordance with the provisions of this Agreement, the Liquidity Provider
makes no representation as to, and assumes no responsibility for, the
correctness or sufficiency for any purpose of the amount of the Advances so
made and requested. Section 2.03Fees

            The Borrower agrees to pay to the Liquidity Provider the fees
set forth in the Fee Letter applicable to this Agreement.

            Section 2.04  Reductions or Termination of the Maximum
Commitment.

            (a) Automatic Reduction. Promptly following each date on which
the Required Amount is reduced as a result of a reduction in the Pool
Balance of the Class G Certificates or otherwise, the Maximum Commitment
shall automatically be reduced to an amount equal to such reduced Required
Amount (as calculated by the Borrower). The Borrower shall give notice of
any such automatic reduction of the Maximum Commitment to the Liquidity
Provider within two Business Days thereof. The failure by the Borrower to
furnish any such notice shall not affect such automatic reduction of the
Maximum Commitment.

            (b) Termination. Upon the making of any Provider Advance or
Final Advance hereunder or the occurrence of the Termination Date, the
obligation of the Liquidity Provider to make further Advances hereunder
shall automatically and irrevocably terminate, and the Borrower shall not
be entitled to request any further Borrowing hereunder.

            Section 2.05  Repayments of Interest Advances or the Final Advance

            Subject to Sections 2.06, 2.07 and 2.09 hereof, the Borrower
hereby agrees, without notice of an Advance or demand for repayment from
the Liquidity Provider (which notice and demand are hereby waived by the
Borrower), to pay, or to cause to be paid, to the Liquidity Provider on
each date on which the Liquidity Provider shall make an Interest Advance or
the Final Advance, an amount equal to (a) the amount of such Advance (any
such Advance, until repaid, is referred to herein as an "Unpaid Advance"),
plus (b) interest on the amount of each such Unpaid Advance as provided in
Section 3.07 hereof; provided that if (i) the Liquidity Provider shall make
a Provider Advance at any time after making one or more Interest Advances
which shall not have been repaid in accordance with this Section 2.05 or
(ii) this Liquidity Facility shall become a Downgraded Facility or
Non-Extended Facility at any time when unreimbursed Interest Advances have
reduced the Maximum Available Commitment to zero, then such Interest
Advances shall cease to constitute Unpaid Advances and shall be deemed to
have been changed into an Applied Downgrade Advance or an Applied
Non-Extension Advance, as the case may be, for all purposes of this
Agreement (including, without limitation, for the purpose of determining
when such Interest Advance is required to be repaid to the Liquidity
Provider in accordance with Section 2.06 and for the purposes of Section
2.06(b)). The Borrower and the Liquidity Provider agree that the repayment
in full of each Interest Advance and Final Advance on the date such Advance
is made is intended to be a contemporaneous exchange for new value given to
the Borrower by the Liquidity Provider.

            Section 2.06  Repayments of Provider Advances

            (a) Amounts advanced hereunder in respect of a Provider Advance
shall be deposited in the Class G Cash Collateral Account, invested and
withdrawn from the Class G Cash Collateral Account as set forth in Sections
3.6(c), (d) and (f) of the Intercreditor Agreement. The Borrower agrees to
pay to the Liquidity Provider, on each Regular Distribution Date,
commencing on the first Regular Distribution Date after the making of a
Provider Advance, interest on the principal amount of any such Provider
Advance as provided in Section 3.07 hereof; provided, however, that amounts
in respect of a Provider Advance withdrawn from the Class G Cash Collateral
Account for the purpose of paying interest on the Class G Certificates in
accordance with Section 3.6(f) of the Intercreditor Agreement (the amount
of any such withdrawal being (y) in the case of a Downgrade Advance, an
"Applied Downgrade Advance" and (z) in the case of a Non-Extension Advance,
an "Applied Non-Extension Advance" and, together with an Applied Downgrade
Advance, an "Applied Provider Advance") shall thereafter (subject to
Section 2.06(b)) be treated as an Interest Advance under this Agreement for
purposes of determining the Applicable Liquidity Rate for interest payable
thereon; provided further, however, that if, following the making of a
Provider Advance, the Liquidity Provider delivers a Termination Notice to
the Borrower pursuant to Section 6.01 hereof, such Provider Advance shall
thereafter be treated as a Final Advance under this Agreement for purposes
of determining the Applicable Liquidity Rate for interest payable thereon.
Subject to Sections 2.07 and 2.09 hereof, immediately upon the withdrawal
of any amounts from the Class G Cash Collateral Account on account of a
reduction in the Required Amount, the Borrower shall repay to the Liquidity
Provider a portion of the Provider Advances in a principal amount equal to
such reduction, plus interest on the principal amount prepaid as provided
in Section 3.07 hereof.

            (b) At any time when an Applied Provider Advance (or any
portion thereof) is outstanding, upon the deposit in the Class G Cash
Collateral Account of any amount pursuant to clause "third" of Section
2.4(b) of the Intercreditor Agreement, clause "third" of Section 3.2 of the
Intercreditor Agreement or clause "fourth" of Section 3.3 of the
Intercreditor Agreement (any such amount being a "Replenishment Amount")
for the purpose of replenishing or increasing the balance thereof up to the
Required Amount at such time, (i) the aggregate outstanding principal
amount of all Applied Provider Advances (and of Provider Advances treated
as an Interest Advance for purposes of determining the Applicable Liquidity
Rate for interest payable thereon) shall be automatically reduced by the
amount of such Replenishment Amount and (ii) the aggregate outstanding
principal amount of all Unapplied Provider Advances shall be automatically
increased by the amount of such Replenishment Amount.

            (c) Upon the provision of a Replacement Liquidity Facility in
replacement of this Agreement in accordance with Section 3.6(e) of the
Intercreditor Agreement, amounts remaining on deposit in the Class G Cash
Collateral Account after giving effect to any Applied Provider Advance on
the date of such replacement shall be reimbursed to the Liquidity Provider,
but only to the extent such amounts are necessary to repay in full to the
Liquidity Provider all amounts owing to it hereunder.

            Section 2.07 Payments to the Liquidity Provider Under the
Intercreditor Agreement

            In order to provide for payment or repayment to the Liquidity
Provider of any amounts hereunder, the Intercreditor Agreement provides
that amounts available and referred to in Articles II and III of the
Intercreditor Agreement, to the extent payable to the Liquidity Provider
pursuant to the terms of the Intercreditor Agreement (including, without
limitation, Section 3.6(f) of the Intercreditor Agreement), shall be paid
to the Liquidity Provider in accordance with the terms thereof. Amounts so
paid to the Liquidity Provider shall be applied by the Liquidity Provider
to Liquidity Obligations then due and payable in accordance with the
Intercreditor Agreement or, if not provided for in the Intercreditor
Agreement, then in such manner as the Liquidity Provider shall deem
appropriate.

            Section 2.08  Book Entries

            The Liquidity Provider shall maintain in accordance with its
usual practice an account or accounts evidencing the indebtedness of the
Borrower resulting from Advances made from time to time and the amounts of
principal and interest payable hereunder and paid from time to time in
respect thereof; provided, however, that the failure by the Liquidity
Provider to maintain such account or accounts shall not affect the
obligations of the Borrower in respect of Advances.

            Section 2.09  Payments from Available Funds Only

            All payments to be made by the Borrower under this Agreement
shall be made only from the amounts that constitute Scheduled Payments,
Special Payments or payments under Section 6(c) or 6(b), as the case may
be, of the Participation Agreements and Section 7 of the Note Purchase
Agreement and only to the extent that the Borrower shall have sufficient
income or proceeds therefrom to enable the Borrower to make payments in
accordance with the terms hereof after giving effect to the priority of
payments provisions set forth in the Intercreditor Agreement. The Liquidity
Provider agrees that it will look solely to such amounts to the extent
available for distribution to it as provided in the Intercreditor Agreement
and this Agreement and that the Borrower, in its individual capacity, is
not personally liable to it for any amounts payable or liability under this
Agreement except as expressly provided in this Agreement, the Intercreditor
Agreement or any Participation Agreement. Amounts on deposit in the Class G
Cash Collateral Account shall be available to the Borrower to make payments
under this Agreement only to the extent and for the purposes expressly
contemplated in Section 3.6(f) of the Intercreditor Agreement.

            Section 2.10  Extension of the Expiry Date; Non-Extension Advance

            The Borrower may, from time to time, by notice to the Liquidity
Provider (each such notice being an "Extension Notice") given no later than
the 40th day and no earlier than the 60th day prior to the then applicable
Expiry Date, request an extension of the Expiry Date to the earlier of (i)
the date which is 15 days after the Final Legal Distribution Date for the
Class G Certificates and (ii) the date that is the day immediately
preceding the 364th day occurring after the last day of the Consent Period
(as hereinafter defined). Whether or not the Liquidity Provider has
received a request from the Borrower, such Liquidity Provider may, but
shall not be obligated to, by a notice (a "Consent Notice") to the
Borrower, given during the period commencing on the date that is 60 days
prior to the Expiry Date then in effect and ending on the date that is 25
days prior to the Expiry Date then in effect for such Liquidity Facility
(such period, with respect to such Liquidity Facility, the "Consent
Period"), consent to such extension of the Expiry Date, which consent may
be given or withheld by the Liquidity Provider in its absolute and sole
discretion; provided, however, that such extension shall not be effective
with respect to the Liquidity Provider if by a notice (a "Withdrawal
Notice") to the Borrower during the Consent Period the Liquidity Provider
revokes its Consent Notice. If a Withdrawal Notice has been given during
the applicable Consent Period or if the Liquidity Provider shall not have
delivered a Consent Notice within the Consent Period (and, in each case, if
the Liquidity Provider shall not have been replaced in accordance with
Section 3.6(e) of the Intercreditor Agreement), the Borrower shall be
entitled on and after the date on which the Consent Period ends (but prior
to the then effective Expiry Date) to request a Non-Extension Advance in
accordance with Section 2.02(b) hereof and Section 3.6(d) of the
Intercreditor Agreement; provided, however, that if (a) the Borrower
delivers a Notice of Borrowing for a Non-Extension Advance after the
expiration of the Consent Period and the Liquidity Provider shall not have
received a request for an extension of the Expiry Date during the Consent
Period, or (b) if the Liquidity Provider shall not have received any
request for such an extension prior to the Expiry Date, the Liquidity
Provider may elect in writing, in the case of clause (a) until the earlier
of (x) the Expiry Date and (y) seven Business Days after receiving such
Notice of Borrowing and in the case of clause (b) at any time prior to the
Expiry Date (if the Expiry Date is not a Business Day, the immediately
preceding Business Day), to extend the Expiry Date to the earlier of (i)
the date which is 15 days after the Final Legal Distribution Date for the
Class G Certificates and (ii) the date that is the day immediately
preceding the 364th day after the date of such election, and, in the case
of clause (a), the obligation of the Liquidity Provider to make such
Non-Extension Advance shall be deferred until the earlier of (x) the Expiry
Date and (y) the next Business Day after such seven Business Day period. If
a Non-Extension Advance shall have been made and the Liquidity Provider
shall not have been replaced within 30 days after the date of such
Non-Extension Advance, or such Non-Extension Advance shall have been made
under the circumstances described in the proviso to the preceding sentence,
the Liquidity Provider may elect in writing to renew the Liquidity Facility
on the terms hereof but with a new Expiry Date which shall be the earlier
of (i) the date which is 15 days after the Final Legal Maturity Date for
the Class G Certificates and (ii) the date that is the day immediately
preceding the 364th day occurring after the date on which such election is
made, and any such renewal shall become effective upon the execution and
delivery of a Replacement Liquidity Facility in accordance with the
provisions of Section 3.6(e) of the Intercreditor Agreement.


                                ARTICLE III
                        OBLIGATIONS OF THE BORROWER

            Section 3.01  Increased Costs.

            The Borrower shall pay to the Liquidity Provider from time to
time such amounts as may be necessary to compensate the Liquidity Provider
for any increased costs incurred by the Liquidity Provider which are
attributable to its making or maintaining any LIBOR Advances hereunder or
its obligation to make any such Advances hereunder, or any reduction in any
amount receivable by the Liquidity Provider under this Agreement or the
Intercreditor Agreement in respect of any such Advances or such obligation
(such increases in costs and reductions in amounts receivable being herein
called "Additional Costs"), resulting from any change after the date of
this Agreement in U.S. federal, state, municipal, or foreign laws or
regulations (including Regulation D of the Board of Governors of the
Federal Reserve System), or the adoption or making after the date of this
Agreement of any interpretations, directives, or requirements applying to a
class of banks including the Liquidity Provider under any U.S. federal,
state, municipal, or any foreign laws or regulations (whether or not having
the force of law) by any court, central bank or monetary authority charged
with the interpretation or administration thereof (a <-1- 34>Regulatory
Change"), which: (1) changes the basis of taxation of any amounts payable
to the Liquidity Provider under this Agreement in respect of any such
Advances (other than Excluded Taxes); or (2) imposes or modifies any
reserve, special deposit, compulsory loan or similar requirements relating
to any extensions of credit or other assets of, or any deposits with other
liabilities of, the Liquidity Provider (including any such Advances or any
deposits referred to in the definition of LIBOR Rate or related
definitions). The Liquidity Provider agrees to use reasonable efforts
(consistent with applicable legal and regulatory restrictions) to change
the jurisdiction of its Facility Office if making such change would avoid
the need for, or reduce the amount of, any amount payable under this
Section that may thereafter accrue and would not, in the reasonable
judgment of the Liquidity Provider, be otherwise disadvantageous to the
Liquidity Provider.

            The Liquidity Provider will notify the Borrower of any event
occurring after the date of this Agreement that will entitle the Liquidity
Provider to compensation pursuant to this Section 3.01 as promptly as
practicable after it obtains knowledge thereof and determines to request
such compensation, which notice shall describe in reasonable detail the
calculation of the amounts owed under this Section. Determinations by the
Liquidity Provider for purposes of this Section 3.01 of the effect of any
Regulatory Change on its costs of making or maintaining Advances or on
amounts receivable by it in respect of Advances, and of the additional
amounts required to compensate the Liquidity Provider in respect of any
Additional Costs, shall be prima facie evidence of the amount owed under
this Section.

            Notwithstanding the preceding two paragraphs, the Liquidity
Provider and the Subordination Agent agree that any permitted assignee or
participant of the initial Liquidity Provider which is not a bank shall not
be entitled to the benefits of the preceding two paragraphs (but without
limiting the provisions of Section 7.08 hereof).

            Section 3.02  Capital Adequacy

            If (1) the adoption, after the date hereof, of any applicable
governmental law, rule or regulation regarding capital adequacy, (2) any
change, after the date hereof, in the interpretation or administration of
any such law, rule or regulation by any central bank or other governmental
authority charged with the interpretation or administration thereof or (3)
compliance by the Liquidity Provider or any corporation controlling the
Liquidity Provider with any applicable guideline or request of general
applicability, issued after the date hereof, by any central bank or other
governmental authority (whether or not having the force of law) that
constitutes a change of the nature described in clause (2), has the effect
of requiring an increase in the amount of capital required to be maintained
by the Liquidity Provider or any corporation controlling the Liquidity
Provider, and such increase is based upon the Liquidity Provider's
obligations hereunder and other similar obligations, the Borrower shall pay
to the Liquidity Provider from time to time such additional amount or
amounts as are necessary to compensate the Liquidity Provider for such
portion of such increase as shall be reasonably allocable to the Liquidity
Provider's obligations to the Borrower hereunder. The Liquidity Provider
agrees to use reasonable efforts (consistent with applicable legal and
regulatory restrictions) to change the jurisdiction of its Facility Office
if making such change would avoid the need for, or reduce the amount of,
any amount payable under this Section that may thereafter accrue and would
not, in the reasonable judgment of the Liquidity Provider, be otherwise
materially disadvantageous to the Liquidity Provider.

            The Liquidity Provider will notify the Borrower of any event
occurring after the date of this Agreement that will entitle the Liquidity
Provider to compensation pursuant to this Section 3.02 as promptly as
practicable after it obtains knowledge thereof and determines to request
such compensation, which notice shall describe in reasonable detail the
calculation of the amounts owed under this Section. Determinations by the
Liquidity Provider for purposes of this Section 3.02 of the effect of any
increase in the amount of capital required to be maintained by the
Liquidity Provider and of the amount allocable to the Liquidity Provider's
obligations to the Borrower hereunder shall be prima facie evidence of the
amounts owed under this Section.

            Notwithstanding the preceding two paragraphs, the Liquidity
Provider and the Subordination Agent agree that any permitted assignee or
participant of the initial Liquidity Provider which is not a bank shall not
be entitled to the benefits of the preceding two paragraphs (but without
limiting the provisions of Section 7.08 hereof).

            Section 3.03  Payments Free of Deductions

            (a) All payments made by the Borrower under this Agreement
shall be made free and clear of, and without reduction for or on account
of, any present or future stamp or other taxes, levies, imposts, duties,
charges, fees, deductions, withholdings, restrictions or conditions of any
nature whatsoever now or hereafter imposed, levied, collected, withheld or
assessed, excluding Excluded Taxes (such non-excluded taxes being referred
to herein, collectively, as "Non-Excluded Taxes" and, individually, as a
"Non-Excluded Tax"). If any Non-Excluded Taxes are required to be withheld
from any amounts payable to the Liquidity Provider under this Agreement,
the amounts so payable to the Liquidity Provider shall be increased to the
extent necessary to yield to the Liquidity Provider (after payment of all
Non-Excluded Taxes) interest or any other such amounts payable under this
Agreement at the rates or in the amounts specified in this Agreement. The
Liquidity Provider agrees to use reasonable efforts (consistent with its
internal policy and legal and regulatory restrictions) to change the
jurisdiction of its Facility Office if making such change would avoid the
need for, or reduce the amount of, any such additional amounts that may
thereafter accrue and would not, in the reasonable judgment of the
Liquidity Provider, be otherwise disadvantageous to the Liquidity Provider.
From time to time upon the reasonable request of the Borrower, the
Liquidity Provider agrees to provide to the Borrower two original Internal
Revenue Service Form W-8BEN or W-8ECI, as appropriate, or any successor or
other form prescribed by the Internal Revenue Service, certifying that the
Liquidity Provider is exempt from or entitled to a reduced rate of United
States withholding tax on payments pursuant to this Agreement.

            (b) All payments (including, without limitation, Advances) made
by the Liquidity Provider under this Agreement shall be made free and clear
of, and without reduction for or on account of, any Taxes. If any Taxes are
required to be withheld or deducted from any amounts payable to the
Borrower under this Agreement, the Liquidity Provider shall (i) within the
time prescribed therefor by applicable law pay to the appropriate
governmental or taxing authority the full amount of any such Taxes (and any
additional Taxes in respect of the additional amounts payable under clause
(ii) hereof) and make such reports or returns in connection therewith at
the time or times and in the manner prescribed by applicable law, and (ii)
pay to the Borrower an additional amount which (after deduction of all such
Taxes) will be sufficient to yield to the Borrower the full amount which
would have been received by it had no such withholding or deduction been
made. Within 30 days after the date of each payment hereunder, the
Liquidity Provider shall furnish to the Borrower the original or a
certified copy of (or other documentary evidence of) the payment of the
Taxes applicable to such payment.

            (c) If any exemption from, or reduction in the rate of, any
Taxes is reasonably available to the Borrower to establish that payments
under this Agreement are exempt from (or entitled to a reduced rate of)
Tax, the Borrower shall deliver to the Liquidity Provider such form or
forms and such other evidence of the eligibility of the Borrower for such
exemption or reduction as the Liquidity Provider may reasonably identify to
the Borrower as being required as a condition to exemption from, or
reduction in the rate of, any Taxes.

            Section 3.04  Payments

            The Borrower shall make or cause to be made each payment to the
Liquidity Provider under this Agreement so as to cause the same to be
received by the Liquidity Provider not later than 1:00 p.m. (New York City
time) on the day when due. The Borrower shall make all such payments in
lawful money of the United States of America, to the Liquidity Provider in
immediately available funds, by wire transfer to First Union Bank
International, Swift/BIC - Code PNBPUS3N NYC (Fedwire 0260 0509 2/CHIPS/ABA
0509) in favor of acount number 2000 193534 122, Bayerische Landesbank
Girozentrale, Munich, Swift/BIC - Code BYLADEMM, Reference Dept. - 7650 -
US Airways Liquidity Facility 2000 1G.

            Section 3.05  Computations

            All computations of interest based on the Base Rate shall be
made on the basis of a year of 365 or 366 days, as the case may be, and all
computations of interest based on the LIBOR Rate shall be made on the basis
of a year of 360 days, in each case for the actual number of days
(including the first day but excluding the last day) occurring in the
period for which such interest is payable.

            Section 3.06  Payment on Non-Business Days

            Whenever any payment to be made hereunder shall be stated to be
due on a day other than a Business Day, such payment shall be made on the
next succeeding Business Day and no additional interest shall be due as a
result (and if so made, shall be deemed to have been made when due). If any
payment in respect of interest on an Advance is so deferred to the next
succeeding Business Day, such deferral shall not delay the commencement of
the next Interest Period for such Advance (if such Advance is a LIBOR
Advance) or reduce the number of days for which interest will be payable on
such Advance on the next interest payment date for such Advance.

            Section 3.07  Interest

            (a) Subject to Section 2.09, the Borrower shall pay, or shall
cause to be paid, without duplication, interest on (i) the unpaid principal
amount of each Advance from and including the date of such Advance (or, in
the case of an Applied Provider Advance, from and including the date on
which the amount thereof was withdrawn from the Class G Cash Collateral
Account to pay interest on the Class G Certificates) to but excluding the
date such principal amount shall be paid in full (or, in the case of an
Applied Provider Advance, the date on which the Class G Cash Collateral
Account is fully replenished in respect of such Advance) and (ii) any other
amount due hereunder (whether fees, commissions, expenses or other amounts
or, to the extent permitted by law, installments of interest on Advances or
any such other amount) which is not paid when due (whether at stated
maturity, by acceleration or otherwise) from and including the due date
thereof to but excluding the date such amount is paid in full, in each such
case, at a fluctuating interest rate per annum for each day equal to the
Applicable Liquidity Rate (as defined below) for such Advance or such other
amount as in effect for such day, but in no event at a rate per annum
greater than the maximum rate permitted by applicable law; provided,
however, that, if at any time the otherwise applicable interest rate as set
forth in this Section 3.07 shall exceed the maximum rate permitted by
applicable law, then any subsequent reduction in such interest rate will
not reduce the rate of interest payable pursuant to this Section 3.07 below
the maximum rate permitted by applicable law until the total amount of
interest accrued equals the amount of interest that would have accrued if
such otherwise applicable interest rate as set forth in this Section 3.07
had at all times been in effect.

            (b) Each Advance will be either a Base Rate Advance or a LIBOR
Advance as provided in this Section. Each such Advance will be a Base Rate
Advance for the period from the date of its borrowing to (but excluding)
the third Business Day following the Liquidity Provider's receipt of the
Notice of Borrowing for such Advance. Thereafter, such Advance shall be a
LIBOR Advance; provided that the Borrower (at the direction of the
Controlling Party, so long as the Liquidity Provider is not the Controlling
Party) may (x) convert the Final Advance into a Base Rate Advance on the
last day of an Interest Period for such Advance by giving the Liquidity
Provider no less than four Business Days' prior written notice of such
election or (y) elect to maintain the Final Advance as a Base Rate Advance
by not requesting a conversion of the Final Advance to a LIBOR Advance
under Clause (5) of the applicable Notice of Borrowing (or, if such Final
Advance is deemed to have been made, without delivery of a Notice of
Borrowing pursuant to Section 2.06, by requesting, prior to 11:00 a.m. on
the first Business Day immediately following the Borrower's receipt of the
applicable Termination Notice, that such Final Advance not be converted
from a Base Rate Advance to a LIBOR Advance).

            (c) Each LIBOR Advance shall bear interest during each Interest
Period at a rate per annum equal to the LIBOR Rate for such Interest Period
plus the Applicable Margin for such LIBOR Advance, payable in arrears on
the last day of such Interest Period and, in the event of the payment of
principal of such LIBOR Advance on a day other than such last day, on the
date of such payment (to the extent of interest accrued on the amount of
principal repaid).

            (d) Each Base Rate Advance shall bear interest at a rate per
annum equal to the Base Rate plus the Applicable Margin for such Base Rate
Advance, payable in arrears on each Regular Distribution Date and, in the
event of the payment of principal of such Base Rate Advance on a day other
than a Regular Distribution Date, on the date of such payment (to the
extent of interest accrued on the amount of principal repaid).

            (e) Each amount not paid when due hereunder (whether fees,
commissions, expenses or other amounts or, to the extent permitted by
applicable law, installments of interest on Advances but excluding
Advances) shall bear interest at a rate per annum equal to the Base Rate
plus 2.00% until paid.

            (f) Each change in the Base Rate shall become effective
immediately. The rates of interest specified in this Section 3.07 with
respect to any Advance or other amount shall be referred to as the <-1-
34>Applicable Liquidity Rate".

            Section 3.08  Replacement of Borrower

            From time to time and subject to the successor Borrower's
meeting the eligibility requirements set forth in Section 6.9 of the
Intercreditor Agreement applicable to the Subordination Agent, upon the
effective date and time specified in a written and completed Notice of
Replacement Subordination Agent in substantially the form of Annex VI
attached hereto (a "Notice of Replacement Subordination Agent<-1-
34>) delivered to the Liquidity Provider by the then Borrower, the
successor Borrower designated therein shall be substituted for as the
Borrower for all purposes hereunder.

            Section 3.09  Funding Loss Indemnification

            The Borrower shall pay to the Liquidity Provider, upon the
request of the Liquidity Provider, such amount or amounts as shall be
sufficient (in the reasonable opinion of the Liquidity Provider) to
compensate it for any loss, cost, or expense incurred by reason of the
liquidation or redeployment of deposits or other funds acquired by the
Liquidity Provider to fund or maintain any LIBOR Advance (but excluding
loss of anticipated profits) incurred as a result of:

            (1) Any repayment of a LIBOR Advance on a date other than the
last day of the Interest Period for such Advance; or

            (2) Any failure by the Borrower to borrow a LIBOR Advance on
the date for borrowing specified in the relevant notice under Section 2.02.

            Section 3.10  Illegality

            Notwithstanding any other provision in this Agreement, if any
change in any applicable law, rule or regulation, or any change in the
interpretation or administration thereof by any governmental authority,
central bank or comparable agency charged with the interpretation or
administration thereof, or compliance by the Liquidity Provider (or its
Facility Office) with any request or directive (whether or not having the
force of law) of any such authority, central bank or comparable agency
shall make it unlawful or impossible for the Liquidity Provider (or its
Facility Office) to maintain or fund its LIBOR Advances, then upon notice
to the Borrower by the Liquidity Provider, the outstanding principal amount
of the LIBOR Advances shall be converted to Base Rate Advances (a)
immediately upon demand of the Liquidity Provider, if such change or
compliance with such request, in the judgment of the Liquidity Provider,
requires immediate repayment; or (b) at the expiration of the last Interest
Period to expire before the effective date of any such change or request.

                  pertaining to the transactions contemplated hereby or by
                  the other Operative Agreements as the Liquidity Provider

this Agreement (regardless of whether indemnified against pursuant to said
Sections or in such Fee Letter)), that may be imposed, incurred by or
asserted against any Liquidity Indemnitee, in any way relating to,
resulting from, or arising out of or in connection with any action, suit or
proceeding by any third party against such Liquidity Indemnitee and
relating to this Agreement, the Fee Letter applicable to this Agreement,
the Intercreditor Agreement or any Financing Agreement; provided, however,
that the Borrower shall not be required to indemnify, protect, defend and
hold harmless any Liquidity Indemnitee in respect of any Expense of such
Liquidity Indemnitee to the extent such Expense is (i) attributable to the
gross negligence or willful misconduct of such Liquidity Indemnitee or any
other Liquidity Indemnitee, (ii) ordinary and usual operating overhead
expense, or (iii) attributable to the failure by such Liquidity Indemnitee
or any other Liquidity Indemnitee to perform or observe any agreement,

            Section 7.06  Liability of the Liquidity Provider

            (a) Neither the Liquidity Provider nor any of its officers,
employees, directors or Affiliates shall be liable or responsible for: (i)
the use which may be made of the Advances or any acts or omissions of the
Borrower or any beneficiary or transferee in connection therewith; (ii) the
validity, sufficiency or genuineness of documents, or of any endorsement
thereon, even if such documents should prove to be in any or all respects
invalid, insufficient, fraudulent or forged; or (iii) the making of
Advances by the Liquidity Provider against delivery of a Notice of
Borrowing and other documents which do not comply with the terms hereof;
provided, however, that the Borrower shall have a claim against the
Liquidity Provider, and the Liquidity Provider shall be liable to the
Borrower, to the extent of any damages suffered by the Borrower which were
the result of (A) the Liquidity Provider's willful misconduct or negligence
in determining whether documents presented hereunder comply with the terms
hereof, or (B) any breach by the Liquidity Provider of any of the terms of
this Agreement, including, but not limited to, the Liquidity Provider's
failure to make lawful payment hereunder after the delivery to it by the
Borrower of a Notice of Borrowing strictly complying with the terms and
conditions hereof.

            (b) Neither the Liquidity Provider nor any of its officers,
employees, directors or Affiliates shall be liable or responsible in any
respect for (i) any error, omission, interruption or delay in transmission,
dispatch or delivery of any message or advice, however transmitted, in
connection with this Agreement or any Notice of Borrowing delivered
hereunder, or (ii) any action, inaction or omission which may be taken by
it in good faith, absent willful misconduct or negligence (in which event
the extent of the Liquidity Provider's potential liability to the Borrower
shall be limited as set forth in the immediately preceding paragraph), in
connection with this Agreement or any Notice of Borrowing.

            Section 7.07 Costs, Expenses and Taxes

            The Borrower agrees to pay, or cause to be paid (A) on the
Effective Date and on such later date or dates on which the Liquidity
Provider shall make demand, all reasonable out-of-pocket costs and expenses
(including, without limitation, the reasonable fees and expenses of outside
counsel for the Liquidity Provider) of the Liquidity Provider in connection
with the preparation, negotiation, execution, delivery, filing and
recording of this Agreement, any other Operative Agreement and any other
documents which may be delivered in connection with this Agreement and (B)
on demand, all reasonable costs and expenses (including reasonable counsel
fees and expenses) of the Liquidity Provider in connection with (i) the
enforcement of this Agreement or any other Operative Agreement, (ii) the
modification or amendment of, or supplement to, this Agreement or any other
Operative Agreement or such other documents which may be delivered in
connection herewith or therewith (whether or not the same shall become
effective) or (iii) any action or proceeding relating to any order,
injunction, or other process or decree restraining or seeking to restrain
the Liquidity Provider from paying any amount under this Agreement, the
Intercreditor Agreement or any other Operative Agreement or otherwise
affecting the application of funds in the Class G Cash Collateral Account.
In addition, the Borrower shall pay any and all recording, stamp and other
similar taxes and fees payable or determined to be payable in connection
with the execution, delivery, filing and recording of this Agreement, any
other Operative Agreement and such other documents, and agrees to save the
Liquidity Provider harmless from and against any and all liabilities with
respect to or resulting from any delay in paying or omission to pay such
taxes or fees.

            Section 7.08 Binding Effect; Participations

            (a) This Agreement shall be binding upon and inure to the
benefit of the Borrower and the Liquidity Provider and their respective
successors and assigns, except that neither the Liquidity Provider (except
as otherwise provided in this Section 7.08) nor (except as contemplated by
Section 3.08) the Borrower shall have the right to assign its rights or
obligations hereunder or any interest herein without the prior written
consent of the other party, subject to the requirements of Section 7.08(b).
The Liquidity Provider may grant participations herein or in any of its
rights hereunder (including, without limitation, funded participations and
participations in rights to receive interest payments hereunder) and under
the other Operative Agreements to such Persons (other than US Airways or
any of its affiliates) as the Liquidity Provider may in its sole discretion
select, subject to the requirements of Section 7.08(b). No such
participation by the Liquidity Provider, however, will relieve the
Liquidity Provider of its obligations hereunder. In connection with any
participation or any proposed participation, the Liquidity Provider may
disclose to the participant or the proposed participant any information
that the Borrower is required to deliver or to disclose to the Liquidity
Provider pursuant to this Agreement. The Borrower acknowledges and agrees
that the Liquidity Provider's source of funds may derive in part from its
participants. Accordingly, references in this Agreement and the other
Operative Agreements to determinations, reserve and capital adequacy
requirements, increased costs, reduced receipts, additional amounts due
pursuant to Section 3.03(a) and the like as they pertain to the Liquidity
Provider shall be deemed also to include those of each of its participants
that are banks (subject, in each case, to the maximum amount that would
have been incurred by or attributable to the Liquidity Provider directly if
the Liquidity Provider, rather than the participant, had held the interest
participated).

            (b) If, pursuant to subsection (a) above, the Liquidity
Provider sells any participation in this Agreement to any bank or other
entity (each, a "Transferee"), then, concurrently with the effectiveness of
such participation, the Transferee shall (i) represent to the Liquidity
Provider (for the benefit of the Liquidity Provider and the Borrower)
either (A) that it is incorporated under the laws of the United States or a
state thereof or (B) that under applicable law and treaties, no taxes will
be required to be withheld with respect to any payments to be made to such
Transferee in respect of this Agreement, (ii) furnish to the Liquidity
Provider and the Borrower either (x) a statement that it is incorporated
under the laws of the United States or a state thereof or (y) if it is not
so incorporated, two copies of a properly completed United States Internal
Revenue Service Form W-8ECI or Form W-8BEN, as appropriate, or other
applicable form, certificate or document prescribed by the Internal Revenue
Service certifying, in each case, such Transferee's entitlement to a
complete exemption from United States federal withholding tax in respect to
any and all payments to be made hereunder, and (iii) agree (for the benefit
of the Liquidity Provider and the Borrower) to provide the Liquidity
Provider and the Borrower a new Form W-8ECI or Form W-8BEN, as appropriate,
(A) on or before the date that any such form expires or becomes obsolete or
(B) after the occurrence of any event requiring a change in the most recent
form previously delivered by it and prior to the immediately following due
date of any payment by the Borrower hereunder, certifying in the case of a
Form W-8BEN or Form W-8ECI that such Transferee is entitled to a complete
exemption from United States federal withholding tax on payments under this
Agreement. Unless the Borrower has received forms or other documents
reasonably satisfactory to it (and required by applicable law) indicating
that payments hereunder are not subject to United States federal
withholding tax, the Borrower will withhold taxes as required by law from
such payments at the applicable statutory rate.

            (c) Notwithstanding the other provisions of this Section 7.08,
the Liquidity Provider may assign and pledge all or any portion of the
Advances owing to it to any Federal Reserve Bank or the United States
Treasury as collateral security pursuant to Regulation A of the Board of
Governors of the Federal Reserve System and any Operating Circular issued
by such Federal Reserve Bank, provided that any payment in respect of such

          (A) the difference between (x) the Pool Balance of such

     occurring after the initial issuance of the Certificates of such
     Trust), and

     the product of (x) the aggregate amount of all accrued and unpaid
     interest on such Policy Drawings not in arrears to such Special

     the applicable Liquidity Facility, the product of (x) the amount of
     such payment made to such Liquidity Provider attributable to interest
     accrued on such Drawings multiplied by (y) the Section 2.4(b)
     Fraction, shall be distributed to the Liquidity Providers and the
     Policy Provider pro rata on the basis of the amount of such Liquidity
     Obligations owed to each Liquidity Provider and the amount of
     unreimbursed Policy Provider Obligations payable under this clause
     "second" to the Policy Provider;

     Facility shall become a Downgraded Facility or a Non-Extended Facility
     at a time when unreimbursed Interest Drawings under such Liquidity
     Facility have reduced the Available Amount thereunder to zero, to

     Liquidity Provider with respect to the principal of any Interest
     Drawing under such Liquidity Facility) under such Liquidity Facility
     and (ii) if the Policy Provider has elected pursuant to the proviso to

     of Drawings under such Liquidity Facility multiplied by (y)the Section
     2.4(b) Fraction, shall be distributed to such Liquidity Provider and
     the Policy Provider, pro rata on the basis of the amounts of all such
     deficiencies and/or unreimbursed Interest Drawings in respect of each
     Liquidity Provider and the amount of unreimbursed Policy Provider
     Obligations payable under this clause "third" to the Policy Provider;

     respect to such Liquidity Facility shall be paid the excess of (x) the
     aggregate outstanding amount of unreimbursed Advances (whether or not
     then due) under such Liquidity Facility over (y) the Required Amount
     for the relevant Class, pro rata on the basis of such amounts in
     respect of each Liquidity Provider;

     fifth, such amount as shall be required to pay in full Expected
     Distributions to the holders of Class G Certificates on such Special
     Distribution Date shall be distributed to the Class G Trustee;

     sixth, such amount as shall be required to pay the Policy Provider all
     Policy Provider Obligations then due to the Policy Provider under the
     Policy Provider Agreement (other than amounts payable pursuant to
     clauses "first", "second" and "third" of this Section 2.4(b)(i) and
     any Excess Reimbursement Obligations) shall be paid to the Policy
     Provider;

due and unpaid interest on such Certificates together with (without
duplication) accrued and unpaid interest on a portion of such Certificates

Payee, directly to the Payee entitled thereto.

     SECTION 2.5. Designated Representatives. (a) With the delivery of
this Agreement, the Subordination Agent shall furnish to each Liquidity
Provider, the Policy Provider and each Trustee, and from time to time
thereafter may furnish to each Liquidity Provider, the Policy Provider and

Responsible Officer of the Subordination Agent certifying as to the
incumbency and specimen signatures of the officers of the Subordination

Provider, the Policy Provider and Trustee receives a subsequent
Subordination Agent Incumbency Certificate, it shall be entitled to rely on
the last Subordination Agent Incumbency Certificate delivered to it
hereunder.

     (b) With the delivery of this Agreement, each Trustee shall furnish to

Provider or Policy Provider certifying as to the incumbency and specimen

Agent receives a subsequent Provider Incumbency Certificate, it shall be
entitled to rely on the last Provider Incumbency Certificate delivered to

     SECTION 2.6. Controlling Party. (a) The Trustees, the Liquidity
Providers and the Policy Provider hereby agree that, with respect to any
Indenture at any given time, the Loan Trustee thereunder will be directed
(i) in taking, or refraining from taking, any action under such Indenture
or with respect to the Equipment Notes issued thereunder, so long as no
Indenture Default has occurred and is continuing thereunder, by the holders
of at least a majority of the outstanding principal amount of such
Equipment Notes (provided that, for so long as the Subordination Agent is
the registered holder of the Equipment Notes, the Subordination Agent shall
act with respect to this clause(i) in accordance with the directions of the
Trustees (in the case of each such Trustee, with respect to the Equipment
Notes issued under such Indenture and held as Trust Property of such Trust)
constituting, in the aggregate, directions with respect to such principal
amount of Equipment Notes) except as provided in Section 9.1(b) hereof, and
(ii) after the occurrence and during the continuance of an Indenture
Default thereunder (which, in the case of an Indenture pertaining to a
Leased Aircraft, has not been cured by the applicable Owner Trustee or the
applicable Owner Participant, if applicable, pursuant to Section4.03 of
such Indenture), in taking, or refraining from taking, any action under
such Indenture or with respect to such Equipment Notes, including
exercising remedies thereunder (including Accelerating the Equipment Notes
issued thereunder or foreclosing the Lien on the Aircraft securing such
Equipment Notes), by the Controlling Party.

     (b) The Person who shall be the "Controlling Party" with respect to
any Indenture upon the occurrence of an Indenture Default thereunder shall
be: (y) the Policy Provider until the Final Distributions on the Class G
Certificates have been made and no Policy Provider Obligations remain
outstanding, or, if any Policy Provider Default shall have occurred and be
continuing or the Policy Provider is required to but has failed to endorse
the Policy under and in accordance with the provisions of Section 3.7(c)
hereof, the Class G Trustee until the payment of the Final Distribution to
the holders of the Class G Certificates; and thereafter, (z) the Class C
Trustee. For purposes of giving effect to the foregoing, the Trustees
(other than the Controlling Party) irrevocably agree (and the
Certificateholders (other than the Certificateholders represented by the
Controlling Party) shall be deemed to agree by virtue of their purchase of
Certificates) that the Subordination Agent, as record holder of the
Equipment Notes, shall exercise its voting rights in respect of the
Equipment Notes as directed by the Controlling Party and any vote so
exercised shall be binding upon the Trustees and all Certificateholders.

     The Subordination Agent shall give written notice to all of the other
parties to this Agreement promptly upon a change in the identity of the
Controlling Party. Each of the parties hereto agrees that it shall not
exercise any of the rights of the Controlling Party at such time as it is
not the Controlling Party hereunder; provided, however, that nothing herein
contained shall prevent or prohibit any Non-Controlling Party from
exercising such rights as shall be specifically granted to such
Non-Controlling Party hereunder and under the other Operative Agreements.

     (c) Notwithstanding the foregoing, at any time after 18 months from
the earliest to occur of (i) the date on which the entire Available Amount
under any Liquidity Facility shall have been drawn (for any reason other
than a Downgrade Drawing or a Non-Extension Drawing) and remain
unreimbursed, (ii) the date on which the entire amount of any Downgrade
Drawing or Non-Extension Drawing under any Liquidity Facility shall have
become and remain "Applied Downgrade Advances" or "Applied Non-Extension
Advances", as the case may be, under and as defined in such Liquidity
Facility and (iii) the date on which all Equipment Notes shall have been
Accelerated (provided that with respect to the period prior to the Delivery
Period Expiry Date, such Equipment Notes have an aggregate outstanding
principal balance in excess of $250,000,000), the Liquidity Provider, if
any, with the highest outstanding amount of Liquidity Obligations then owed
to it and not then in default in its obligations to make any Advance under
any Liquidity Facility shall have the right to elect, by Written Notice to
the Subordination Agent, the Policy Provider and each of the Trustees, to
become the Controlling Party hereunder with respect to any Indenture at any
time from and including the last day of such 18-month period; provided,
however, that if within 15 Business Days after its receipt of any such
written notice from such Liquidity Provider (A) (i) the Policy Provider
then meets the Policy Provider Threshold Rating and (ii) the Policy
Provider delivers to the Subordination Agent (with a copy to each of the
Trustees and each Liquidity Provider) (a) an endorsement to the Policy (x)
extending the benefits of the Policy to and covering in full all Drawings
under each Liquidity Facility together with accrued interest thereon
(determined without regard to the availability of funds for the payment
thereof by the Subordination Agent) in respect of such Liquidity Facility,
(y) permitting each Liquidity Provider when and as such Liquidity
Obligations become due under the applicable Liquidity Facility to demand a
payment thereof under such endorsed Policy directly from the Policy
Provider and (z) prohibiting any amendment or modification of such endorsed
Policy without the prior written consent of each Liquidity Provider and
otherwise in form and substance reasonably satisfactory to each Liquidity
Provider, (b) a legal opinion addressed to the Liquidity Providers to the
effect that the Policy as endorsed constitutes an enforceable obligation of
the Policy Provider and (c) a Ratings Confirmation issued by each Rating
Agency with respect thereto or (B) the Policy Provider pays to the
Liquidity Provider all outstanding Drawings under each Liquidity Facility
together with accrued interest thereon (as so determined) in respect of
such Liquidity Facility, then, in either case, the Policy Provider rather
than such Liquidity Provider shall be the Controlling Party so long as no
Policy Provider Default has occurred and is continuing (in which case such
Liquidity Provider, if it so elects and if Liquidity Obligations owing to
it remain outstanding, or, if it does not so elect or if no such Liquidity
Obligations remain outstanding, the Class G Trustee, shall become the
Controlling Party). In connection with the delivery of any such endorsement
to the Policy, the parties hereto agree to enter into an amendment to this
Agreement and the Subordination Agent agrees to enter into an amendment to
the Policy Provider Agreement, in each instance, to make such changes
thereto as may be necessary to give effect to the foregoing (any such
amendment to this Agreement to be subject to delivery to each of the
Trustees and the Subordination Agent of a Ratings Confirmation issued by
each Rating Agency with respect thereto and each such amendment to be in
form and substance reasonably satisfactory to each party thereto). In
addition, each Liquidity Provider agrees to request the Policy Drawings
permitted by such endorsed Policy and that the proceeds thereof shall be
applied to reduce, pro tanto, the Liquidity Obligations owing to it in the
following order: first, to accrued and unpaid Liquidity Expenses; second,
to interest accrued and unpaid on Liquidity Obligations; and third, to all
other Liquidity Obligations.

     (d) The exercise of remedies by the Controlling Party under this
Agreement shall be expressly limited by Section 4.1(a)(ii) hereof.

     (e) The Controlling Party shall not be entitled to require or obligate
any Non-Controlling Party to provide funds necessary to exercise any right
or remedy hereunder.

     may be, shall be distributed to the Subordination Agent and such
     Trustee; and

          tenth, the balance, if any, of any such amount remaining
     thereafter shall be held in the Collection Account for later
     distribution in accordance with this Article III.

     SECTION 3.3. Distribution of Amounts on Deposit Following a Triggering

3.6(k) hereof, upon the occurrence of a Triggering Event and at all times

     the Subordination Agent in reimbursement of such costs and expenses,
     (ii) each Trustee for any amounts of the nature described in clause

     shortfall attributable to a failure by any Liquidity Provider to honor
     any Interest Drawing (as more fully provided in the definition of
     "Policy Provider Obligations"), and (iii) if the Policy Provider has
     elected pursuant to the proviso to Section 2.6(c) to pay to each
     Liquidity Provider all outstanding Drawings and interest thereon owing
     to such Liquidity Provider under the applicable Liquidity Facility,
     the amount of such payment made to such Liquidity Provider
     attributable to interest accrued on such Drawings, shall be
     distributed to the Liquidity Providers and the Policy Provider pro
     rata on the basis of the amount of such Liquidity Obligations owed to
     each Liquidity Provider and the amount of such Policy Provider
     Obligations payable under this clause "third" to the Policy Provider;

            fourth, such amount remaining as shall be required (I) (A) if
      any Cash Collateral Account had been previously funded as provided in
      Section 3.6(f), unless (i) a Performing Note Deficiency exists and a
      Liquidity Event of Default shall have occurred and be continuing with
      respect to the relevant Liquidity Facility or (ii) a Final Drawing
      shall have occurred with respect to such Liquidity Facility, to fund
      such Cash Collateral Account up to its Required Amount (less the

      deposited in such Cash Collateral Account, (B) if any Liquidity
      Facility shall become a Downgraded Facility or a Non-Extended
      Facility at a time when unreimbursed Interest Drawings under such
      Liquidity Facility have reduced the Available Amount thereunder to
      zero, unless (i) a Performing Note Deficiency exists and a Liquidity
      Event of Default shall have occurred and be continuing with respect
      to the relevant Liquidity Facility or (ii) a Final Drawing shall have
      occurred with respect to such Liquidity Facility, to deposit into the
      related Cash Collateral Account an amount equal to such Cash
      Collateral Account's Required Amount (less the amount of any
      repayments of Interest Drawings under such Liquidity Facility while
      subclause (B)(i) above is applicable) shall be deposited in such Cash
      Collateral Account, and (C) if, with respect to any particular
      Liquidity Facility, neither subclause (I)(A) nor subclause (I)(B) of
      this clause "fourth" are applicable, to pay in full the outstanding
      amount of all Liquidity Obligations (net of any and all payments made
      by the Policy Provider to the applicable Liquidity Provider) then due
      under such Liquidity Facility (other than amounts payable pursuant to
      clause "second" or "third" of this Section 3.3), and (II) if the
      Policy Provider has elected pursuant to the proviso to Section 2.6(c)
      to pay to each Liquidity Provider all outstanding Drawings and
      interest thereon owing to such Liquidity Provider under the
      applicable Liquidity Facility, the amount of such payment made to
      such Liquidity Provider in respect of principal of Drawings under
      such Liquidity Facility, shall be distributed to such Liquidity
      Provider and the Policy Provider, pro rata on the basis of the
      amounts of all such deficiencies and/or unreimbursed Liquidity
      Obligations in respect of each Liquidity Provider and the amount of
      unreimbursed Policy Provider Obligations payable under this clause

      respect to such Liquidity Facility shall be paid the excess of (x)
      the aggregate outstanding amount of unreimbursed Advances (whether or
      not then due) under such Liquidity Facility over (y) the Required
      Amount for the relevant Class (less the amount of any repayments of
      Interest Drawings under such Liquidity Facility while subclause
      (I)(A)(i) or (I)(B)(i), as the case may be, of clause "fourth" above
      is applicable), pro rata on the basis of such amounts in respect of
      each Liquidity Provider;

            sixth, such amount as shall be required to reimburse or pay (i)
      the Subordination Agent for any Tax (other than Taxes imposed on
      compensation paid hereunder), expense, fee, charge or other loss
      incurred by or any other amount payable to the Subordination Agent in
      connection with the transactions contemplated hereby (to the extent
      not previously reimbursed), shall be applied by the Subordination
      Agent in reimbursement of such amount, (ii) each Trustee for any Tax
      (other than Taxes imposed on compensation paid under the applicable
      Trust Agreement), expense, fee, charge, loss or any other amount
      payable to such Trustee under the applicable Trust Agreements (to the
      extent not previously reimbursed), shall be distributed to such
      Trustee, and (iii) each Certificateholder for payments, if any, made
      by it pursuant to Section 5.2 hereof in respect of amounts described
      in clause (i) above, shall be distributed to the applicable Trustee

      rata on the basis of all amounts described in clauses (i) through
      (iii) above;

            seventh, such amount remaining as shall be required to pay in

      Provider all Policy Provider Obligations then due to the Policy
      Provider under the Policy Provider Agreement (other than amounts

      of this Section 3.3 and Excess Reimbursement Obligations) shall be
      paid to the Policy Provider;

            ninth, such amount remaining as shall be required to pay in
      full Adjusted Expected Distributions on the Class C Certificates
      shall be distributed to the Class C Trustee; and

            tenth, such amount remaining as shall be required to pay in
      full any Excess Reimbursement Obligations shall be distributed to the
      Policy Provider.

            SECTION 3.4. Other Payments. (a) Any payments received by the
Subordination Agent for which no provision as to the application thereof is
made in this Agreement shall be distributed by the Subordination Agent (i)
in the order of priority specified in Section 3.3 hereof and (ii) to the
extent received or realized at any time after the Final Distributions for
each Class of Certificates have been made, in the manner provided in clause
"first" of Section 3.3 hereof.

            (b) On any Interest Payment Date under each Liquidity Facility
which is not a Distribution Date, the Subordination Agent shall pay to the
Liquidity Provider under such Liquidity Facility from, and to the extent
of, amounts on deposit in the Collection Account, an amount equal to the
amount of interest then due and payable to such Liquidity Provider under
such Liquidity Facility.

            (c) Except as otherwise provided in Section 3.3 hereof, if the
Subordination Agent receives any Scheduled Payment after the Scheduled
Payment Date relating thereto, but prior to such payment becoming an
Overdue Scheduled Payment, then the Subordination Agent shall deposit such
Scheduled Payment in the Collection Account and promptly distribute such
Scheduled Payment in accordance with the priority of distributions set
forth in Section 3.2 hereof; provided that, for the purposes of this
Section 3.4(c) only, each reference in clause "ninth" of Section 3.2 to
"Distribution Date" shall be deemed to mean the actual date of payment of
such Scheduled Payment and each reference in clause "fifth" or "seventh" of
Section 3.2 to "Distribution Date" shall be deemed to refer to such
Scheduled Payment Date.

            SECTION 3.5. Payments to the Trustees, the Liquidity Providers
and the Policy Provider. Any amounts distributed hereunder to any Liquidity
Provider or the Policy Provider shall be paid to such Liquidity Provider or
Policy Provider by wire transfer of funds to the address such Liquidity
Provider or Policy Provider shall provide to the Subordination Agent. The
Subordination Agent shall provide a Written Notice of any such transfer to
the applicable Liquidity Provider or Policy Provider, as the case may be,
at the time of such transfer. Any amounts distributed hereunder by the
Subordination Agent to any Trustee which shall not be the same institution
as the Subordination Agent shall be paid to such Trustee by wire transfer
funds at the address such Trustee shall provide to the Subordination Agent.
The Policy Provider shall not have any claim against the Trust Property for
any Trust in respect of any amounts that the Policy Provider is entitled to
receive by virtue of the subrogation rights of the Policy Provider under
the Escrow and Paying Agent Agreement for the Class G Trust, including,
without limitation, fees and expenses incurred in connection with the
enforcement of such rights.

            SECTION 3.6.  Liquidity Facilities.  (a)  Interest
Drawings.  If on any Distribution Date, after giving effect to the
subordination provisions of this Agreement, the Subordination Agent
shall not have sufficient funds for the payment of any amounts due
and owing in respect of accrued interest on the Class G
Certificates or the Class C Certificates (at the Stated Interest
Rate for such Class of Certificates), then, prior to 1:00 p.m.(New
York City time) on such Distribution Date, the Subordination Agent
shall request a drawing (each such drawing, an "Interest Drawing")
under the Liquidity Facility with respect to such Class of
Certificates (and concurrently with the making of such request, the
Subordination Agent shall give notice to the Policy Provider of
such insufficiency of funds) in an amount equal to the lesser of
(i) an amount sufficient to pay the amount of such accrued interest
(at the Stated Interest Rate for such Class of Certificates) and
(ii) the Available Amount under such Liquidity Facility, and shall
pay such amount to the Trustee with respect to such Class of
Certificates in payment of such accrued interest.

            (b) Application of Interest Drawings. Notwithstanding anything
to the contrary contained in this Agreement, (i) all payments received by
the Subordination Agent in respect of an Interest Drawing under the Class G
Liquidity Facility and all amounts withdrawn by the Subordination Agent
from the Class G Cash Collateral Account, and payable in each case to the
Class G Trustee on behalf of the Class G Certificateholders, shall be
promptly distributed to the Class G Trustee and (ii) all payments received
by the Subordination Agent in respect of an Interest Drawing under the
Class C Liquidity Facility and all amounts withdrawn by the Subordination
Agent from the Class C Cash Collateral Account, and payable in each case to
the Class C Trustee on behalf of the Class C Certificateholders, shall be
promptly distributed to the Class C Trustee, except that if after any
Distribution Date the Subordination Agent shall receive any amount in
respect of an Interest Drawing under the Class G Liquidity Facility or a
withdrawal from the Class G Cash Collateral Account to pay Accrued Class G
Interest, after such Accrued Class G Interest has been fully paid by a
Policy Drawing under the Policy, such amounts shall be paid directly to the
Policy Provider as reimbursement of such Policy Drawing rather than to the
Class G Trustee on behalf of the Class G Certificateholders and shall
constitute an Interest Drawing under the Class G Liquidity Facility
hereunder.

            (c) Downgrade Drawings. If at any time the short-term unsecured
debt rating of any Liquidity Provider issued by either Rating Agency is
lower than the applicable Threshold Rating, within 10 days after receiving
notice of such downgrading (but not later than the expiration date of the
Liquidity Facility issued by the downgraded Liquidity Provider (the
"Downgraded Facility")), such Liquidity Provider or US Airways may arrange
for a Replacement Liquidity Provider to issue and deliver a Replacement
Liquidity Facility to the Subordination Agent. If a Downgraded Facility has
not been replaced in accordance with the terms of this paragraph, the
Subordination Agent shall, on such 10th day (or if such 10th day is not a
Business Day, on the next succeeding Business Day) (or, if earlier, the
expiration date of such Downgraded Facility), request a drawing in
accordance with and to the extent permitted by such Downgraded Facility
(such drawing, a "Downgrade Drawing") of all available and undrawn amounts
thereunder. Amounts drawn pursuant to a Downgrade Drawing shall be
maintained and invested as provided in Section 3.6(f) hereof. The
applicable Liquidity Provider may also arrange for a Replacement Liquidity
Provider to issue and deliver a Replacement Liquidity Facility at any time
after such Downgrade Drawing so long as such Downgrade Drawing has not been
reimbursed in full to such Liquidity Provider.

            (d) Non-Extension Drawings. If any Liquidity Facility with
respect to any Class of Certificates is scheduled to expire on a date (the
"Stated Expiration Date") prior to the date that is 15 days after the Final
Legal Distribution Date for such Class of Certificates, then, no earlier
than the 60th day and no later than the 40th day prior to the then Stated
Expiration Date, the Subordination Agent shall request that such Liquidity
Provider extend the Stated Expiration Date until the earlier of (i) the
date which is 15 days after such Final Legal Distribution Date and (ii) the
date that is the day immediately preceding the 364th day occurring after
the last day of the applicable Consent Period (as hereinafter defined)
(unless the obligations of such Liquidity Provider thereunder are earlier
terminated in accordance with such Liquidity Facility). Whether or not such
Liquidity Provider has received a request from the Subordination Agent,
such Liquidity Provider may, but shall not be obligated to, by a notice (a
"Consent Notice") to the Subordination Agent, given during the period
commencing on the date that is 60 days prior to the stated Expiration Date
then in effect and ending on the date that is 25 days prior to the Stated
Expiration Date then in effect for such Liquidity Facility (such period,
with respect to such Liquidity Facility, the "Consent Period"), consent to
such extension of such Stated Expiration Date, which consent may be given
or withheld by such Liquidity Provider in its absolute and sole discretion;
provided, however, that such extension shall not be effective with respect
to such Liquidity Provider if by a notice (a "Withdrawal Notice") to the
Subordination Agent during the applicable Consent Period such Liquidity
Provider revokes its Consent Notice. If (A) on or before such 25th day,
such Liquidity Facility shall not have been replaced in accordance with
Section 3.6(e), and (B) a Withdrawal Notice has been given with respect to
such Liquidity Facility during the applicable Consent Period or the
applicable Liquidity Provider shall not have delivered a Consent Notice
with respect to such Liquidity Facility within the applicable Consent
Period, the Subordination Agent shall, on such 25th day (or as soon as
possible thereafter), in accordance with the terms of the expiring
Liquidity Facility (a "Non-Extended Facility"), request a drawing under
such expiring Liquidity Facility (such drawing, a "Non-Extension Drawing")
of all available and undrawn amounts thereunder; provided, however, that if
(a) the Subordination Agent delivers a Notice of Borrowing for a
Non-Extension Drawing after the expiration of the Consent Period and the
Liquidity Provider shall not have received a request for an extension of
the Stated Expiration Date during the Consent Period, or (b) if the
Liquidity Provider shall not have received any request for such an
extension prior to the Stated Expiration Date, the Liquidity Provider may
elect in writing, in the case of clause (a) until the earlier of (x) the
Stated Expiration Date and (y) seven Business Days after receiving such
Notice of Borrowing and in the case of clause (b) at any time prior to the
Stated Expiration Date (and if the Stated Expiration Date is not a Business
Day, the immediately preceding Business Day), to extend the Stated
Expiration Date to the earlier of (i) the date which is 15 days after the
Final Legal Distribution Date for the applicable Class of Certificates and
(ii) the date that is the day immediately preceding the 364th day after the
date of such election, and, in the case of clause (a), the obligation of
the Liquidity Provider to make such Non-Extension Drawing shall be deferred
until the earlier of (x) the Stated Expiration Date and (y) the next
Business Day after such seven Business Day period. Amounts drawn pursuant
to a Non-Extension Drawing shall be maintained and invested in accordance
with Section 3.6(f) hereof. If a Non-Extension Drawing shall have been made
and the applicable Liquidity Provider shall not have been replaced within
30 days after the date of such Non-Extension Drawing or such Non-Extension
Drawing shall have been made under the circumstances described in the
proviso to the second immediately preceding sentence, the applicable
Liquidity Provider may elect in writing to renew the applicable Liquidity
Facility on the terms hereof but with a new Stated Expiration Date which
shall be the earlier of (i) the date which is 15 days after the Final Legal
Distribution Date for the applicable Class of Certificates to which such
Liquidity Facility relates and (ii) the date that is the day immediately
preceding the 364th day occurring after the date on which such election is
made, and any such renewal shall become effective upon the execution and
delivery of a Replacement Liquidity Facility in accordance with the
provisions of Section 3.6(e).

            (e) Issuance of Replacement Liquidity Facility. (i) At any
time, US Airways may, at its option, with cause or without cause, arrange
for a Replacement Liquidity Facility to replace any Liquidity Facility for
any Class of Certificates (including any Replacement Liquidity Facility
provided pursuant to Section 3.6(e)(ii) hereof); provided, however, that if
the initial Liquidity Provider is replaced for one or more Liquidity
Facilities it must be replaced for all remaining Liquidity Facilities and
the initial Liquidity Provider for any Liquidity Facility shall not be
replaced by US Airways as a Liquidity Provider with respect to such
Liquidity Facility prior to the ninth anniversary of the Closing Date
unless (A) there shall have become due to such initial Liquidity Provider,
or such initial Liquidity Provider shall have demanded, amounts pursuant to
Section 3.01, 3.02 or 3.03 of any applicable Liquidity Facility or pursuant
to the Tax Letter(s) and the replacement of such initial Liquidity Provider
would reduce or eliminate the obligation to pay such amounts or US Airways
determines in good faith that there is a substantial likelihood that such
initial Liquidity Provider will have the right to claim any such amounts
within 180 days after the date of such determination (unless such initial
Liquidity Provider waives, in writing, any right it may have to claim such
amounts), which determination shall be set forth in a certificate delivered
by US Airways to such initial Liquidity Provider setting forth the basis
for such determination and accompanied by an opinion of outside counsel
selected by US Airways and reasonably acceptable to such initial Liquidity
Provider verifying the legal conclusions, if any, of such certificate
relating to such basis, provided that, in the case of any likely claim for
such amounts based upon any proposed, or proposed change in, law, rule,
regulation, interpretation, directive, requirement, request or
administrative practice, such opinion may assume the adoption or
promulgation of such proposed matter, (B) it shall become unlawful or
impossible for such initial Liquidity Provider (or its Facility Office) to
maintain or fund its LIBOR Advances as described in Section 3.10 of any
Liquidity Facility, (C) any Liquidity Facility of such initial Liquidity
Provider shall become a Downgraded Facility or a Non-Extended Facility or a
Downgrade Drawing or a Non-Extension Drawing shall have occurred under any
Liquidity Facility of such initial Liquidity Provider or (D) such initial
Liquidity Provider shall have breached any of its payment (including,
without limitation, funding) obligations under any Liquidity Facility in
respect of which it is the Liquidity Provider. If such Replacement
Liquidity Facility is provided at any time after a Downgrade Drawing or
Non-Extension Drawing has been made, all funds on deposit in the relevant
Cash Collateral Account will be returned to the Liquidity Provider being
replaced.

            (ii) If any Liquidity Provider shall determine not to extend
any of its Liquidity Facilities in accordance with Section 3.6(d), then
such Liquidity Provider may, at its option, arrange for a Replacement
Liquidity Facility to replace such Liquidity Facility during the period no
earlier than 40 days and no later than 25 days prior to the then effective
Stated Expiration Date of such Liquidity Facility.

            (iii) No Replacement Liquidity Facility arranged by US Airways
or a Liquidity Provider in accordance with clause (i) or (ii) above or
pursuant to Section 3.6(c), respectively, shall become effective and no
such Replacement Liquidity Facility shall be deemed a "Liquidity Facility"
under the Operative Agreements (in each case other than insofar as
necessary to permit the repayment of amounts owed to the replaced Liquidity
Provider), unless and until (A) each of the conditions referred to in this
clause (iii) and clause (iv) below shall have been satisfied, (B) if such
Replacement Liquidity Facility shall materially adversely affect the
rights, remedies, interests or obligations of the Class G
Certificateholders or the Class C Certificateholders under any of the
Operative Agreements, the applicable Trustee shall have consented, in
writing, to the execution and issuance of such Replacement Liquidity
Facility and (C) in the case of a Replacement Liquidity Facility arranged
by a Liquidity Provider under Section 3.6(e)(ii) or pursuant to Section
3.6(c), such Replacement Liquidity Facility is reasonably acceptable to US
Airways.

            (iv) In connection with the issuance of each Replacement
Liquidity Facility, the Subordination Agent shall (x) prior to the issuance
of such Replacement Liquidity Facility, obtain written confirmation from
each Rating Agency that such Replacement Liquidity Facility will not cause
a reduction of any rating then in effect for any Class of Certificates by
such Rating Agency (without regard to any downgrading of any rating of any
Liquidity Provider being replaced pursuant to Section 3.6(c), 3.6(e)(i) or
3.6(e)(ii) hereof and without regard to the Policy) and, in the case of the
Class G Liquidity Facility, the written consent of the Policy Provider
(which consent shall not be unreasonably withheld or delayed), (y) pay all
Liquidity Obligations then owing to the replaced Liquidity Provider (which
payment shall be made first from available funds in the applicable Cash
Collateral Account as described in clause (v) of Section 3.6(f) hereof, and
thereafter from any other available source, including, without limitation,
a drawing under the Replacement Liquidity Facility) and (z) cause the
issuer of the Replacement Liquidity Facility to deliver the Replacement
Liquidity Facility to the Subordination Agent, together with a legal
opinion opining that such Replacement Liquidity Facility is an enforceable
obligation of such Replacement Liquidity Provider.

            (v) Upon satisfaction of the conditions set forth in clauses
(iii) and (iv) of this Section 3.6(e) with respect to a Replacement
Liquidity Facility, (w) the replaced Liquidity Facility shall terminate,
(x) the Subordination Agent shall, if and to the extent so requested by US
Airways or the Liquidity Provider being replaced, execute and deliver any
certificate or other instrument required in order to terminate the replaced
Liquidity Facility, shall surrender the replaced Liquidity Facility to the
Liquidity Provider being replaced and shall execute and deliver the
Replacement Liquidity Facility and any associated Fee Letter(s), (y) each
of the parties hereto shall enter into any amendments to this Agreement
necessary to give effect to (1) the replacement of the applicable Liquidity
Provider with the applicable Replacement Liquidity Provider and (2) the
replacement of the applicable Liquidity Facility with the applicable
Replacement Liquidity Facility and (z) the applicable Replacement Liquidity
Provider shall be deemed to be a Liquidity Provider with the rights and
obligations of a Liquidity Provider hereunder and under the other Operative
Agreements and such Replacement Liquidity Facility shall be deemed to be a
Liquidity Facility hereunder and under the other Operative Agreements.

            (f) Cash Collateral Accounts; Withdrawals; Investments. In the
event the Subordination Agent shall draw all available amounts under the
Class G Liquidity Facility or the Class C Liquidity Facility pursuant to
Section 3.6(c), 3.6(d) or 3.6(i) hereof, or in the event amounts are to be
deposited in a Cash Collateral Account pursuant to subclause (i)(B) of
clause "third" of Section 2.4(b), subclause (i)(B) of clause "third" of
Section 3.2 or subclause (I)(B) of clause "fourth" of Section 3.3, amounts
so drawn or to be deposited, as the case may be, shall be deposited by the
Subordination Agent in the Class G Cash Collateral Account or the Class C
Collateral Account, respectively. All amounts on deposit in each Cash
Collateral Account shall be invested and reinvested in Eligible Investments
in accordance with Section 2.2(b) hereof. On each Interest Payment Date
(or, in the case of any Special Distribution Date occurring prior to the
occurrence of a Triggering Event on such Special Distribution Date),
Investment Earnings on amounts on deposit in each Cash Collateral Account
(or, in the case of any Special Distribution Date occurring prior to the
occurrence of a Triggering Event, a fraction of such Investment Earnings
equal to the Section 2.4(b) Fraction) shall be deposited in the Collection
Account (or, in the case of any Special Distribution Date occurring prior
to the occurrence of a Triggering Event, the Special Payments Account) and
applied on such Interest Payment Date (or Special Distribution Date, as the
case may be) in accordance with Section 2.4, 3.2, 3.3 or 3.4 (as
applicable). The Subordination Agent shall deliver a written statement to
US Airways, the Policy Provider and the Liquidity Provider one day prior to
each Interest Payment Date and Special Distribution Date setting forth the
aggregate amount of Investment Earnings held in the Cash Collateral
Accounts as of such date. In addition, from and after the date funds are so
deposited, the Subordination Agent shall make withdrawals from such account
as follows:

            (i) on each Distribution Date, the Subordination Agent shall,
      to the extent it shall not have received funds to pay accrued and
      unpaid interest due and owing on the Class G Certificates (at the
      Stated Interest Rate for the Class G Certificates) from any other
      source, withdraw from the Class G Cash Collateral Account, and pay to
      the Class G Trustee, an amount equal to the lesser of (x) an amount
      necessary to pay accrued and unpaid interest (at the Stated Interest
      Rate for the Class G Certificates) on such Class G Certificates and
      (y) the amount on deposit in the Class G Cash Collateral Account;

            (ii) on each Distribution Date, the Subordination Agent shall,
      to the extent it shall not have received funds to pay accrued and
      unpaid interest due and owing on the Class C Certificates (at the
      Stated Interest Rate for the Class C Certificates) from any other
      source, withdraw from the Class C Cash Collateral Account, and pay to
      the Class C Trustee, an amount equal to the lesser of (x) an amount
      necessary to pay accrued and unpaid interest (at the Stated Interest
      Rate for the Class C Certificates) on such Class C Certificates and
      (y) the amount on deposit in the Class C Cash Collateral Account;

            (iii) on each date on which the Pool Balance of the Class G
      Trust shall have been reduced by payments made to the Class G
      Certificateholders pursuant to Section 2.4, 3.2 or 3.3 hereof or
      pursuant to Section 2.03 of the Escrow and Paying Agent Agreement for
      such Class, the Subordination Agent shall withdraw from the Class G
      Cash Collateral Account such amount as is necessary so that, after
      giving effect to the reduction of the Pool Balance on such date
      (including any such reduction resulting from a prior withdrawal of
      amounts on deposit in the Class G Cash Collateral Account on such
      date) and any transfer of Investment Earnings from such Cash
      Collateral Account to the Collection Account or the Special Payments
      Account on such date, an amount equal to the sum of the Required
      Amount (with respect to the Class G Liquidity Facility) plus (if on a
      Special Distribution Date not coinciding with an Interest Payment
      Date) Investment Earnings on deposit in such Cash Collateral Account
      will be on deposit in the Class G Cash Collateral Account and shall
      first, pay such withdrawn amount to the Class G Liquidity Provider
      until the Liquidity Obligations (with respect to the Class G
      Certificates) owing to such Liquidity Provider shall have been paid
      in full, and second, deposit any remaining withdrawn amount in the
      Collection Account;

            (iv) on each date on which the Pool Balance of the Class C
      Trust shall have been reduced by payments made to the Class C
      Certificateholders pursuant to Section 2.4, 3.2 or 3.3 hereof or
      pursuant to Section 2.03 of the Escrow and Paying Agent Agreement for
      such Class, the Subordination Agent shall withdraw from the Class C
      Cash Collateral Account such amount as is necessary so that, after
      giving effect to the reduction of the Pool Balance on such date
      (including any such reduction resulting from a prior withdrawal of
      amounts on deposit in the Class C Cash Collateral Account on such
      date) and any transfer of Investment Earnings from such Cash
      Collateral Account to the Collection Account or the Special Payments
      Account on such date, an amount equal to the sum of the Required
      Amount (with respect to the Class C Liquidity Facility) plus (if on a
      Special Distribution Date not coinciding with an Interest Payment
      Date) Investment Earnings on deposit in such Cash Collateral Account
      will be on deposit in the Class C Cash Collateral Account and shall
      first, pay such withdrawn amount to the Class C Liquidity Provider
      until the Liquidity Obligations (with respect to the Class C
      Certificates) owing to such Liquidity Provider shall have been paid
      in full, and second, deposit any remaining withdrawn amount in the
      Collection Account;

            (v) if a Replacement Liquidity Facility for any Class of
      Certificates shall be delivered to the Subordination Agent following
      the date on which funds have been deposited into the Cash Collateral
      Account for such Class of Certificates, the Subordination Agent shall
      withdraw all amounts on deposit in such Cash Collateral Account and
      shall pay such amounts to the replaced Liquidity Provider until all
      Liquidity Obligations owed to such Person shall have been paid in
      full, and shall deposit any remaining amount in the Collection
      Account; and

            (vi) following the payment of Final Distributions with respect
      to any Class of Certificates, on the date on which the Subordination
      Agent shall have been notified by the Liquidity Provider for such
      Class of Certificates that the Liquidity Obligations owed to such
      Liquidity Provider have been paid in full, the Subordination Agent
      shall withdraw all amounts on deposit in the Cash Collateral Account
      in respect of such Class of Certificates and shall deposit such
      amount in the Collection Account.

            (g) Reinstatement. With respect to any Interest Drawing under
the Liquidity Facility for any Trust, upon the reimbursement of the
applicable Liquidity Provider for all or any part of the amount of such
Interest Drawing, together with any accrued interest thereon, the Available
Amount of such Liquidity Facility shall be reinstated by an amount equal to
the amount of such Interest Drawing so reimbursed to the applicable
Liquidity Provider but not to exceed the Required Amount for such Liquidity
Facility; provided, however, that such Liquidity Facility shall not be so
reinstated in part or in full at any time if (x) both a Performing Note
Deficiency exists and a Liquidity Event of Default shall have occurred and
be continuing with respect to the relevant Liquidity Facility or (y) a
Final Drawing shall have occurred with respect to such Liquidity Facility.
In the event that, with respect to any particular Liquidity Facility (i)
funds are withdrawn from any Cash Collateral Account pursuant to clauses
(i) and (ii) of Section 3.6(f) hereof or (ii) such Liquidity Facility shall
become a Downgraded Facility or a Non-Extended Facility at a time when
unreimbursed Interest Drawings under such Liquidity Facility have reduced
the Available Amount thereunder to zero, then funds received by the
Subordination Agent at any time other than (x) any time when a Liquidity
Event of Default shall have occurred and be continuing with respect to such
Liquidity Facility and a Performing Note Deficiency exists or (y) any time
after a Final Drawing shall have occurred with respect to such Liquidity
Facility shall be deposited in such Cash Collateral Account as and to the
extent provided in clause "third" of Section 2.4(b), clause "third" of
Section 3.2 or clause "fourth" of Section 3.3, as applicable, and applied
in accordance with Section 3.6(f) hereof.

            (h) Reimbursement. The amount of each drawing under the
Liquidity Facilities shall be due and payable, together with interest
thereon, on the dates and at the rates, respectively, provided in the
Liquidity Facilities.

            (i) Final Drawing. Upon receipt from a Liquidity Provider of a
Termination Notice with respect to any Liquidity Facility, the
Subordination Agent shall, not later than the date specified in such
Termination Notice, in accordance with the terms of such Liquidity
Facility, request a drawing under such Liquidity Facility of all available
and undrawn amounts thereunder (a "Final Drawing"). Amounts drawn pursuant
to a Final Drawing shall be maintained and invested in accordance with
Section 3.6(f) hereof.

            (j) Reduction of Stated Amount. Promptly following each date on
which the Required Amount of the Liquidity Facility for a Class of
Certificates is reduced as a result of a reduction in the Pool Balance with
respect to such Certificates, the Subordination Agent shall, if any such
Liquidity Facility provides for reductions of the Stated Amount of such
Liquidity Facility and if such reductions are not automatic, request such
Liquidity Provider for such Class of Certificates to reduce such Stated
Amount to an amount equal to the Required Amount with respect to such
Liquidity Facility (as calculated by the Subordination Agent after giving
effect to such payment). Each such request shall be made in accordance with
the provisions of the applicable Liquidity Facility.

            (k) Relation to Subordination Provisions. Interest Drawings
under the Liquidity Facilities and withdrawals from the Cash Collateral
Accounts, in each case, in respect of interest on the Certificates of any
Class, will be distributed to the Trustee for such Class of Certificates
for distribution to Certificateholders of the related Class,
notwithstanding Sections 2.4(b), 3.2, 3.3 and 3.6(h) hereof.

            (l) Assignment of Liquidity Facility. The Subordination Agent
agrees not to consent to the assignment by any Liquidity Provider of any of
its rights or obligations under any Liquidity Facility or any interest
therein, unless (i) US Airways shall have consented to such assignment,
(ii) each Rating Agency shall have provided a Ratings Confirmation in
respect of such assignment and (iii) in the case of the Class G Liquidity
Facility only, the Policy Provider shall have consented to such assignment
(which consent shall not be unreasonably withheld or delayed).

            SECTION 3.7. The Policy. (a) Interest Drawings. If on any
Regular Distribution Date (other than the Final Legal Distribution Date)
after giving effect to the subordination provisions of this Agreement and
to the application of Prior Funds, the Subordination Agent does not then
have sufficient funds available for the payment of all amounts due and
owing in respect of accrued and unpaid interest on the Class G Certificates
and, without duplication, accrued and unpaid interest at the Stated
Interest Rate for the Class G Certificates on any Deposit relating to the
Escrow Receipts, in each case at the Stated Interest Rate for the Class G
Certificates on the Pool Balance of the Class G Certificates on such
Distribution Date ("Accrued Class G Interest"), then, prior to 1:00 p.m.
(New York City time) on such Distribution Date, the Subordination Agent (i)
shall deliver a Notice for Payment, as provided in the Policy, to the
Policy Provider or its fiscal agent, requesting a Policy Drawing under the
Policy (for payment into the Policy Account) in an amount sufficient to
enable the Subordination Agent to pay such Accrued Class G Interest and
(ii) shall pay such amount from the Policy Account to the Class G Trustee
or the Escrow Agent for the Class G Trust for deposit into the Class G
Paying Agent Account, as the case may be, in payment of such Accrued Class
G Interest on such Distribution Date.

            (b) Proceeds Deficiency Drawing. If on any Special Distribution
Date (which is not also an Election Distribution Date or a Special
Distribution Date established pursuant to clause (c)(i) in the second
paragraph of Section 3.7(c) below) established by the Subordination Agent
by reason of its receipt of a Special Payment constituting the proceeds of
any Series G Equipment Note (as to which there has been a default in the
payment of principal thereof or that has been Accelerated) or the related
Trust Indenture Estate or Indenture Estate, as the case may be, and if on
such Special Distribution Date after giving effect to the subordination
provisions of this Agreement and to the application of Prior Funds, the
Subordination Agent does not then have sufficient funds available for a
reduction in the outstanding Pool Balance of the Class G Certificates by an
amount equal to the outstanding principal amount of such Equipment Note
(determined immediately prior to the receipt of such proceeds) plus accrued
and unpaid interest on the amount of such reduction at the Stated Interest
Rate for the Class G Certificates for the period from the immediately
preceding Regular Distribution Date to such Special Distribution Date,
then, prior to 1:00 p.m. (New York City time) on such Special Distribution
Date, the Subordination Agent (i) shall deliver a Notice for Payment, as
provided in the Policy (for payment into the Policy Account) in an amount
sufficient to enable the Subordination Agent to pay the amount of such
reduction plus such accrued and unpaid interest and (ii) shall pay such
amount from the Policy Account to the Class G Trustee in payment of such
reduction in the outstanding Pool Balance of the Class G Certificates plus
such accrued and unpaid interest on such Special Distribution Date.

            (c) No Proceeds Drawing. If the Subordination Agent has not
received a Special Payment constituting proceeds from the sale of any
Series G Equipment Note or the related Trust Indenture Estate or Indenture
Estate (a "Disposition"), as the case may be, during the 18-month period
beginning on the last date on which any payment was made in full on such
Series G Equipment Note (the date of such payment in full, the "Last
Payment Date") as to which there has been a failure to pay principal or
that has been Accelerated subsequent to the Last Payment Date, then on the
first Business Day following the expiration of such 18-month period, the
Subordination Agent shall deliver a Notice for Payment, as provided in the
Policy, to the Policy Provider or its fiscal agent, requesting a Policy
Drawing under the Policy (for payment into the Policy Account) in an amount
equal to the then outstanding principal amount of such Equipment Note plus
accrued and unpaid interest thereon at the Stated Interest Rate for the
Class G Certificates from the immediately preceding Regular Distribution
Date to the below referred to Special Distribution Date. The Subordination
Agent shall promptly, but not less than 25 days prior to such Business Day,
send to the Class G Trustee a Written Notice setting forth the non-receipt
of any such Special Payment and establishing such Business Day as the date
for the distribution of the proceeds of such Policy Drawing, which date
shall constitute a Special Distribution Date. No later than 1:00 p.m. (New
York City time) on the specified Special Distribution Date the
Subordination Agent shall make the specified Policy Drawing and upon its
receipt of the proceeds thereof pay the amount thereof from the Policy
Account to the Class G Trustee in reduction of the outstanding Pool Balance
of the Class G Certificates together with such accrued and unpaid interest
thereon. For the avoidance of doubt, after the payment in full of such
amount under this Section 3.7(c), the Subordination Agent shall have no
right to make any further Policy Drawings under this Section 3.7(c) in
respect of any Disposition of or in respect of such Equipment Note except
for Avoided Payments as provided in Section 3.7(e).

            Notwithstanding the foregoing, the Policy Provider has the
right at the end of any such 18-month period, so long as no Policy Provider
Default shall have occurred and be continuing and so long as the Policy
Provider has not defaulted in its obligations (if any) to endorse the
Policy as provided in the next paragraph of this Section 3.7(c), to elect
(the "Policy Provider Election") instead (a) to pay on such Special
Distribution Date an amount equal to any shortfall in the scheduled
principal and interest payable but not paid on such Series G Equipment Note
(without regard to the Acceleration thereof) during such 18-month period
(after giving effect to the application of funds received from the Class G
Liquidity Facility or the Class G Cash Collateral Account, in each case
attributable to such interest), (b) thereafter, on each Regular
Distribution Date until the establishment of an Election Distribution Date
or a Special Distribution Date referred to in clause (c)(i) below, to
permit drawings under the Policy for an amount equal to the scheduled
principal (without regard to the Acceleration thereof) and interest payable
on such Equipment Note on the related payment date and (c) (i) on any
Business Day (which shall be a Special Distribution Date) elected by the
Policy Provider upon 20 days' Written Notice to the Subordination Agent and
the Class G Trustee to request the Subordination Agent, or (ii) following
either the occurrence and continuation of a Policy Provider Default or a
Disposition of or in respect of such Equipment Note on any Business Day
(which shall be a Special Distribution Date) specified by the Subordination
Agent upon 20 days' Written Notice to the Class G Trustee (each such
Business Day in the case of clause (ii) an "Election Distribution Date"),
to permit the Subordination Agent, in each case, to make a Policy Drawing
for an amount equal to the then outstanding principal balance of such
Equipment Note (less any Policy Drawings previously paid by the Policy
Provider in respect of principal of such Equipment Note) and accrued and
unpaid interest on such amounts at the Stated Interest Rate for the Class G
Certificates, from the immediately preceding Regular Distribution Date to
such Election Distribution Date or such Special Distribution Date (after
giving effect to the application of funds, if any, received on such
Election Distribution Date or such Special Distribution Date from the Class
G Liquidity Facility or the Class G Cash Collateral Account attributable to
such interest) and without derogation of the Policy Provider's continuing
obligations for all previous Policy Drawings that remain unpaid in respect
of such Equipment Note. The Subordination Agent shall make each such
drawing referred to in this paragraph under the Policy (for payment into
the Policy Account) no later than 1:00 p.m. (New York City time) on each
such date and upon its receipt of the proceeds thereof pay the amount
thereof from the Policy Account to the Class G Trustee in reduction of the
outstanding Pool Balance of the Class G Certificates together with such
accrued and unpaid interest thereon.

            In addition, regardless of whether or not the Policy Provider
makes a Policy Provider Election, the Policy Provider shall, at the end of
such 18-month period, provide to the Trustees and each Liquidity Provider
to the extent not previously provided (a) an endorsement to the Policy (x)
providing for the payment to each Liquidity Provider of interest accruing
on all outstanding Drawings under such Liquidity Provider's Liquidity
Facility together with accrued interest thereon in respect of such
Liquidity Facility from and after the end of such 18-month period, (y)
permitting each Liquidity Provider when and as such interest becomes due
under the applicable Liquidity Facility to demand payment thereof directly
from the Policy Provider under such endorsed Policy (each such demand, an
"Excess Interest Policy Drawing") and (z) prohibiting any amendment or
modification of such endorsed Policy without the prior written consent of
each Liquidity Provider and (b) a legal opinion to the effect that the
Policy as endorsed constitutes an enforceable obligation of the Policy
Provider. Each Liquidity Provider agrees to make such Excess Interest
Policy Drawings and that the proceeds thereof shall reduce pro tanto the
Liquidity Obligations owing to it.

            (d) Final Policy Drawing. If on the applicable Final Legal
Distribution Date of the Class G Certificates after giving effect to the
subordination provisions of this Agreement and to the application of Prior
Funds, the Subordination Agent does not then have sufficient funds
available on such date for the payment in full of the Final Distributions
(calculated as at such date but excluding any accrued and unpaid premium)
on such Class of Certificates then, prior to 1:00 p.m. (New York City time)
on such date the Subordination Agent shall: (i) deliver a Notice for
Payment, as provided in the Policy, to the Policy Provider or its fiscal
agent, requesting a Policy Drawing under the Policy (for payment into the
Policy Account) in an amount equal to the minimum amount sufficient to
enable the Subordination Agent to pay the Final Distributions (calculated
as at such date but excluding any accrued and unpaid premium) on such Class
of Certificates, and (ii) shall pay such amount from the Policy Account to
the Class G Trustee in payment of such amount on such date.

            (e) Avoidance Drawings. If at any time prior to the expiration
of the Policy the Subordination Agent shall have actual knowledge of the
issuance of any Order, the Subordination Agent shall promptly give notice
thereof to each Trustee, the Liquidity Providers and the Policy Provider.
The Subordination Agent shall thereupon calculate the relevant Avoided
Payment resulting therefrom and shall promptly: (a) send to the Class G
Trustee a Written Notice of such amount and (b) prior to the expiration of
the Policy, deliver to the Policy Provider or its fiscal agent a Notice of
Avoided Payment, together with a copy of the documentation required by the
Policy with respect thereto, requesting a Policy Drawing (for payment to
the receiver, conservator, debtor-in-possession or trustee in bankruptcy
and/or to the Subordination Agent for deposit into the Policy Account, as
applicable) in an amount equal to the amount of the relevant Avoided
Payment. To the extent that any portion of such Avoided Payment is to be
paid to the Subordination Agent, such Written Notice shall also set the
date for the distribution of such portion of the proceeds of such Policy
Drawing which date shall constitute a Special Distribution Date and shall
be the earlier of three Business Days after the date of the expiration of
the Policy and the Business Day that immediately follows the 25th day after
the date of such Written Notice. No later than 1:00 p.m. (New York City
time) on the specified Special Distribution Date, the Subordination Agent
shall make the specified Policy Drawing upon its receipt of the proceeds
thereof and pay the amount thereof from the Policy Account to the Class G
Trustee in reinstatement of the Avoided Payment.

            (f) Application of Policy Drawings. Notwithstanding anything to
the contrary contained in this Agreement (including, without limitation,
Sections 2.4, 3.2 and 3.3 hereof), all payments received by the
Subordination Agent in respect of a Policy Drawing (including, without
limitation, that portion, if any, of the proceeds of a Policy Drawing for
any Avoided Payment that is to be paid to the Subordination Agent and not
to any receiver, conservator, debtor-in-possession or trustee in bankruptcy
as provided in the Policy) shall be promptly paid from the Policy Account
to the Class G Trustee for distribution to the Class G Certificateholders
or the holders of the Escrow Receipts, as the case may be.

            (g) Limitation to Outstanding Pool Balance. Promptly following
each date on which the Pool Balance of the Class G Certificates is reduced
as a result of payment under this Agreement, the Subordination Agent shall
inform the Policy Provider of such reduction. Notwithstanding anything to
the contrary in this Section 3.7, except as provided in Section 3.7(e), at
no time shall the Subordination Agent make (i) any Policy Drawing for
payment in respect of the Class G Certificates under clause (b), (c) or (d)
of this Section 3.7 in excess of the then outstanding Pool Balance of the
Class G Certificates and accrued and unpaid interest at the Stated Interest
Rate on the Class G Certificates or (ii) any Policy Drawing for payment in
respect of the Class G Certificates under clause (a) of this Section 3.7 in
excess of Accrued Class G Interest. Nothing contained in this Intercreditor
Agreement shall alter or amend the liabilities, obligations, requirements
or procedures of the Policy Provider under the Policy and the Policy
Provider shall not be obligated to make payment except at the times and in
the amounts and under the circumstances expressly set forth in the Policy.

            (h) Resubmission of Notice for Payment. If the Policy Provider
at any time informs the Subordination Agent in accordance with the Policy
that a Notice for Payment or Notice of Avoided Payment submitted by the
Subordination Agent does not meet the requirements of the Policy, the
Subordination Agent shall, as promptly as possible after being so informed,
submit to the Policy Provider an amended and revised Notice for Payment or
Notice of Avoided Payment, as the case may be, and shall pay to the Class G
Trustee out of the Policy Account the amount received pursuant to such
amended or revised Notice for Payment or Notice of Avoided Payment, as the
case may be, when received.

            (i) Reimbursement Obligation. The Policy Provider shall be
entitled to reimbursement in full for (i) any payment made by the Policy
Provider under the Policy in an amount equal to the sum of the amount so
paid and all other amounts previously paid that remain unreimbursed, which
reimbursement amount shall be due and owing to the Policy Provider on the
date payment is made under the Policy, (ii) if the Policy Provider has,
pursuant to either clause (A) or (B) of the proviso to Section 2.6(c), paid
to each Liquidity Provider all outstanding Drawings and interest thereon
owing to such Liquidity Provider under the applicable Liquidity Facility,
such payment and interest (accrued at the rate of the Base Rate plus 1% per
annum) on the unreimbursed amount of such payment from and including the
date of such payment to but excluding the date such payment shall be
reimbursed in full (without duplication of amounts reimbursable under the
foregoing clause (i)), (iii) any and all charges, fees, costs and expenses
and disbursements that the Policy Provider may reasonably pay or incur,
including reasonable attorneys' and accountants' fees and expenses (without
duplication of amounts paid to the Policy Provider in respect of the
Operative Agreements), in connection with the enforcement, defense or
preservation of any rights in respect of any of the Operative Agreements,
including defending, monitoring or participating in any litigation or
proceeding (which reimbursement obligation shall be due on the date of
presentation of an invoice therefor to the Subordination Agent and US
Airways and to the extent not paid), (iv) all Rating Agency fees, expenses
and disbursements payable by the Policy Provider at any time after the
Closing Date (without duplication of amounts paid to the Policy Provider in
respect of the Operative Agreements) in connection with the Policy Provider
Agreement and the transactions described herein (which reimbursement
obligation shall be due on the date of presentation of an invoice therefor
to the Subordination Agent and US Airways), (v) all reasonable and actual
fees, expenses and disbursements (including those of legal counsel)
incurred by the Policy Provider after the Closing Date (without duplication
of amounts paid to the Policy Provider in respect of the Operative
Agreements) in connection with the Policy Provider Agreement and the
transactions described herein and any modification, waiver, amendment,
revision or similar action of the Operative Agreements and all other
documents delivered with respect thereto (which reimbursement obligation
shall be due on the date of presentation of an invoice therefor to the
Subordination Agent and US Airways), and (vi) interest on Policy Drawings
to the extent provided in the definition of "Policy Provider Obligations"
herein; provided, that in the case of each of the foregoing clauses (i),
(ii), (iii), (iv), (v) and (vi), such reimbursement (A) shall not include
any amounts that the Policy Provider is entitled to receive by virtue of
the subrogation rights of the Policy Provider under the Escrow and Paying
Agent Agreement for the Class G Trust, including, without limitation, fees
and expenses incurred in connection with the enforcement of such rights,
and (B) shall be payable only from and to the extent of the funds available
under and at the time and in the priority specified therefor in Sections
2.4(b), 3.2 and 3.3 hereof, as applicable.

            (j) Payment Information. All payments to the Policy Provider
hereunder shall be made in lawful currency of the United States and in
immediately available funds and shall be made prior to 2:00 p.m. (New York
City time) on the date such payment is due by wire transfer to The Chase
Manhattan Bank, ABA #021000021 for credit to MBIA Insurance Corporation,
Account No. 910-2-721728 Re: US Airways Pass Through Trust 2000-1G or to

                                 ARTICLE IV

                            EXERCISE OF REMEDIES

            SECTION 4.1. Directions from the Controlling Party. (a) (i)
Following the occurrence and during the continuation of an Indenture
Default under any Indenture, the Controlling Party shall direct the
Subordination Agent, which in turn shall direct the Loan Trustee under such
Indenture, in the exercise of remedies available to the holders of the
Equipment Notes issued pursuant to such Indenture, including, without
limitation, the ability to vote all such Equipment Notes in favor of
Accelerating such Equipment Notes in accordance with the provisions of such
Indenture. Subject to the Owner Trustees' and the Owner Participants'
rights, if any, set forth in the Indentures with respect to Leased Aircraft
to purchase the Equipment Notes and the provisions of the next paragraph,
if the Equipment Notes issued pursuant to any Indenture have been
Accelerated following an Indenture Default with respect thereto, the
Controlling Party may sell, assign, contract to sell or otherwise dispose
of and deliver all (but not less than all) of such Equipment Notes to any
Person at public or private sale, at any location at the option of the
Controlling Party, all upon such terms and conditions as it may reasonably
deem advisable in accordance with applicable law.

            (ii) Subject to the Owner Trustees' and the Owner Participants'
rights, if any, set forth in the Indentures with respect to Leased Aircraft
to purchase the Equipment Notes, and notwithstanding the foregoing, so long
as any Certificates remain Outstanding, during the period ending on the
date which is nine months after the earlier of (x) the Acceleration of the
Equipment Notes issued pursuant to any Indenture or (y) the occurrence of a
US Airways Bankruptcy Event, without the consent of each Trustee, (A) no
Aircraft subject to the Lien of such Indenture or such Equipment Notes may
be sold if the net proceeds from such sale would be less than the Minimum
Sale Price for such Aircraft or such Equipment Notes, and (B) with respect
to any Leased Aircraft, the amount and payment dates of rentals payable by
US Airways under the Lease for such Aircraft may not be adjusted, if, as a
result of such adjustment, the discounted present value of all such rentals
would be less than 75% of the discounted present value of the rentals
payable by US Airways under such Lease before giving effect to such
adjustment, in each case, using the weighted average interest rate of the
Equipment Notes issued pursuant to such Indenture as the discount rate.

            (iii) At the request of the Controlling Party, the
Subordination Agent may from time to time during the continuance of an
Indenture Default (and before the occurrence of a Triggering Event)
commission LTV Appraisals with respect to the Aircraft subject to such
Indenture.

            (iv) After a Triggering Event occurs and any Equipment Note
becomes a Non-Performing Equipment Note, the Subordination Agent shall
obtain Appraisals with respect to all of the Aircraft (the "LTV
Appraisals") as soon as practicable and additional LTV Appraisals on or
prior to each anniversary of the date of such initial LTV Appraisals;
provided that if the Controlling Party reasonably objects to the appraised
value of the Aircraft shown in such LTV Appraisals, the Controlling Party
shall have the right to obtain or cause to be obtained substitute LTV
Appraisals (including any LTV Appraisals based upon physical inspection of
the Aircraft).

            (b) The Controlling Party shall take such actions as it may
reasonably deem most effectual to complete the sale or other disposition of
such Aircraft or Equipment Notes. In addition, in lieu of any sale,
assignment, contract to sell or other disposition, the Controlling Party
may maintain or cause the Subordination Agent to maintain possession of
such Equipment Notes and continue to apply monies received in respect of
such Equipment Notes in accordance with Article III hereof. In addition, in
lieu of such sale, assignment, contract to sell or other disposition, or in
lieu of such maintenance of possession, the Controlling Party may, subject
to the terms and conditions of the related Indenture, instruct the Loan
Trustee under such Indenture to foreclose on the Lien on the related
Aircraft or to take any other remedial action permitted under such
Indenture or under any applicable law.

            SECTION 4.2. Remedies Cumulative. Each and every right, power
and remedy given to the Trustees, the Liquidity Providers, the Policy
Provider, the Controlling Party or the Subordination Agent specifically or
otherwise in this Agreement shall be cumulative and shall be in addition to
every other right, power and remedy herein specifically given or now or
hereafter existing at law, in equity or by statute, and each and every
right, power and remedy whether specifically herein given or otherwise
existing may, subject always to the terms and conditions hereof, be
exercised from time to time and as often and in such order as may be deemed
expedient by any Trustee, any Liquidity Provider, the Policy Provider, the
Controlling Party or the Subordination Agent, as appropriate, 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 any
Trustee, any Liquidity Provider, the Policy Provider, the Controlling Party
or the Subordination Agent in the exercise of any right, remedy or power or
in the pursuit of any remedy shall impair any such right, power or remedy
or be construed to be a waiver of any default or to be an acquiescence
therein.

            SECTION 4.3. Discontinuance of Proceedings. In case any party
to this Agreement (including the Controlling Party in such capacity) shall
have instituted any Proceeding to enforce any right, power or remedy under
this Agreement by foreclosure, entry or otherwise, and such Proceeding
shall have been discontinued or abandoned for any reason or shall have been
determined adversely to the Person instituting such Proceeding, then and in
every such case each such party shall, subject to any determination in such
Proceeding, be restored to its former position and rights hereunder, and
all rights, remedies and powers of such party shall continue as if no such
Proceeding had been instituted.

            SECTION 4.4. Right of Certificateholders to Receive Payments
Not to Be Impaired. Anything in this Agreement to the contrary
notwithstanding but subject to each Trust Agreement, the right of any
Certificateholder, any Liquidity Provider or the Policy Provider,
respectively, to receive payments hereunder (including without limitation

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

            SECTION 4.5. Undertaking for Costs. In any Proceeding for the
enforcement of any right or remedy under this Agreement or in any
Proceeding against any Controlling Party or the Subordination Agent for any
action taken or omitted by it as Controlling Party or Subordination Agent,

party litigant in the suit of an undertaking to pay the costs of the suit,
and the court in its discretion may assess reasonable costs, including
reasonable attorneys' fees and expenses, against any party litigant in the
suit, having due regard to the merits and good faith of the claims or
defenses made by the party litigant. The provisions of this Section do not
apply to a suit instituted by the Subordination Agent, a Liquidity
Provider, the Policy Provider or a Trustee or a suit by Certificateholders
holding more than 10% of the original principal amount of any Class of
Certificates.


                                 ARTICLE V

                     DUTIES OF THE SUBORDINATION AGENT;
                        AGREEMENTS OF TRUSTEES, ETC.

            SECTION 5.1. Notice of Indenture Default or Triggering Event.
(a) In the event the Subordination Agent shall have actual knowledge of the
occurrence of an Indenture Default or a Triggering Event, as promptly as
practicable, and in any event within 10 days after obtaining knowledge
thereof, the Subordination Agent shall transmit by mail or courier to the
Rating Agencies, the Liquidity Providers, the Policy Provider and the
Trustees notice of such Indenture Default or Triggering Event, unless such
Indenture Default or Triggering Event shall have been cured or waived by
the Controlling Party. For all purposes of this Agreement, in the absence
of actual knowledge on the part of a Responsible Officer, the Subordination
Agent shall not be deemed to have knowledge of any Indenture Default or
Triggering Event unless notified in writing by one or more Trustees, one or
more Liquidity Providers or the Policy Provider or one or more
Certificateholders.

            (b) Other Notices. The Subordination Agent will furnish to each
Liquidity Provider, the Policy Provider and each Trustee, promptly upon
receipt thereof, duplicates or copies of all reports, notices, requests,
demands, certificates, financial statements and other instruments furnished
to the Subordination Agent as registered holder of the Equipment Notes or
otherwise in its capacity as Subordination Agent to the extent the same
shall not have been otherwise directly distributed to such Liquidity
Provider, Policy Provider or Trustee, as applicable, pursuant to the
express provision of any other Operative Agreement.

            SECTION 5.2. Indemnification . The Subordination Agent shall
not be required to take any action or refrain from taking any action under
Section 5.1 (other than the first sentence thereof) or Article IV hereof
unless the Subordination Agent shall have been indemnified (to the extent
and in the manner reasonably satisfactory to the Subordination Agent)
against any liability, cost or expense (including counsel fees and
expenses) which may be incurred in connection therewith. The Subordination
Agent shall not be under any obligation to take any action under this
Agreement and nothing contained in this Agreement shall require the
Subordination Agent to expend or risk its own funds or otherwise incur any
financial liability in the performance of any of its duties hereunder or in
the exercise of any of its rights or powers if it shall have reasonable
grounds for believing that repayment of such funds or adequate indemnity
against such risk or liability is not reasonably assured to it. The
Subordination Agent shall not be required to take any action under Section
5.1 (other than the first sentence thereof) or Article IV hereof, nor shall
any other provision of this Agreement be deemed to impose a duty on the
Subordination Agent to take any action, if the Subordination Agent shall
have been advised by counsel that such action is contrary to the terms
hereof or is otherwise contrary to law.

            SECTION 5.3. No Duties Except as Specified in Intercreditor
Agreement. The Subordination Agent shall not have any duty or obligation to
take or refrain from taking any action under, or in connection with, this
Agreement, except as expressly provided by the terms of this Agreement; and
no implied duties or obligations shall be read into this Agreement against
the Subordination Agent. The Subordination Agent agrees that it will, in
its individual capacity and at its own cost and expense (but without any
right of indemnity in respect of any such cost or expense under Section 5.2
or Section 7.1 hereof) promptly take such action as may be necessary to
duly discharge all Liens on any of the Trust Accounts or any monies
deposited therein which result from claims against it in its individual
capacity not related to its activities hereunder or any other Operative
Agreement.

            SECTION 5.4. Notice from the Liquidity Providers and Trustees.
If any Liquidity Provider or Trustee has notice of an Indenture Default or
a Triggering Event, such Person shall promptly give notice thereof to all
other Liquidity Providers, the Policy Provider and Trustees and to the
Subordination Agent, provided, however, that no such Person shall have any
liability hereunder as a result of its failure to deliver any such notice.


                                 ARTICLE VI

                          THE SUBORDINATION AGENT

            SECTION 6.1. Authorization; Acceptance of Trusts and Duties.
Each of the Class G Trustee and the Class C Trustee (if any) hereby
designates and appoints the Subordination Agent as the agent and trustee of
such Trustee under the applicable Liquidity Facility and, in the case of
the Class G Trustee, the Policy Provider Agreement and authorizes the
Subordination Agent to enter into the applicable Liquidity Facility (and,
in the case of the Class G Trustee, the Policy Provider Agreement) as agent
and trustee for such Trustee. Each of the Liquidity Providers, the Policy
Provider and the Trustees hereby designates and appoints the Subordination
Agent as the Subordination Agent under this Agreement. State Street hereby
accepts the duties hereby created and applicable to it as the Subordination
Agent and agrees to perform the same but only upon the terms of this
Agreement and agrees to receive and disburse all monies received by it in
accordance with the terms hereof. The Subordination Agent shall not be
answerable or accountable under any circumstances, except (a) for its own
willful misconduct or gross negligence (or ordinary negligence in the
handling of funds), (b) as provided in Sections 2.2 and 5.3 hereof and (c)
for liabilities that may result from the material inaccuracy of any
representation or warranty of the Subordination Agent made in its
individual capacity in any Operative Agreement. The Subordination Agent
shall not be liable for any error of judgment made in good faith by a
Responsible Officer of the Subordination Agent, unless it is proved that
the Subordination Agent was negligent in ascertaining the pertinent facts.

            SECTION 6.2. Absence of Duties. The Subordination Agent shall
have no duty to see to any recording or filing of this Agreement or any
other document, or to see to the maintenance of any such recording or
filing.

            SECTION 6.3. No Representations or Warranties as to Documents.
The Subordination Agent in its individual capacity does not make nor shall
be deemed to have made any representation or warranty as to the validity,
legality or enforceability of this Agreement or any other Operative
Agreement or as to the correctness of any statement contained in any
thereof, except for the representations and warranties of the Subordination
Agent, made in its individual capacity, under any Operative Agreement to
which it is a party. The Certificateholders, the Trustees, the Liquidity
Providers and the Policy Provider make no representation or warranty
hereunder whatsoever.

            SECTION 6.4. No Segregation of Monies; No Interest. Any monies
paid to or retained by the Subordination Agent pursuant to any provision
hereof and not then required to be distributed to any Trustee, any
Liquidity Provider or the Policy Provider as provided in Articles II and
III hereof or deposited into one or more Trust Accounts need not be
segregated in any manner except to the extent required by such Articles II
and III and by law, and the Subordination Agent shall not (except as
otherwise provided in Section 2.2 hereof) be liable for any interest
thereon; provided, however, that any payments received or applied hereunder
by the Subordination Agent shall be accounted for by the Subordination
Agent so that any portion thereof paid or applied pursuant hereto shall be
identifiable as to the source thereof.

            SECTION 6.5. Reliance; Agents; Advice of Counsel. The
Subordination Agent shall not incur liability to anyone in acting upon any
signature, instrument, notice, resolution, request, consent, order,
certificate, report, opinion, bond or other document or paper believed by
it to be genuine and believed by it to be signed by the proper party or
parties. As to the Pool Balance of any Trust as of any date, the
Subordination Agent may for all purposes hereof rely on a certificate
signed by any Responsible Officer of the applicable Trustee, and such
certificate shall constitute full protection to the Subordination Agent for
any action taken or omitted to be taken by it in good faith in reliance
thereon. As to any fact or matter relating to the Liquidity Providers, the
Policy Provider or the Trustees the manner of ascertainment of which is not
specifically described herein, the Subordination Agent may for all purposes
hereof rely on a certificate, signed by any Responsible Officer of the
applicable Liquidity Provider, Policy Provider or Trustee, as the case may
be, as to such fact or matter, and such certificate shall constitute full
protection to the Subordination Agent for any action taken or omitted to be
taken by it in good faith in reliance thereon. The Subordination Agent
shall assume, and shall be fully protected in assuming, that each of the
Liquidity Providers, the Policy Provider and each of the Trustees are
authorized to enter into this Agreement and to take all action to be taken
by them pursuant to the provisions hereof, and shall not inquire into the
authorization of each of the Liquidity Providers, the Policy Provider and
each of the Trustees with respect thereto. In the administration of the
trusts hereunder, the Subordination Agent may execute any of the trusts or
powers hereof and perform its powers and duties hereunder directly or
through agents or attorneys and may consult with counsel, accountants and
other skilled persons to be selected and retained by it, and the
Subordination Agent shall not be liable for the acts or omissions of any
agent appointed with due care or for anything done, suffered or omitted in
good faith by it in accordance with the advice or written opinion of any
such counsel, accountants or other skilled persons.

            SECTION 6.6. Capacity in Which Acting. The Subordination Agent
acts hereunder solely as agent and trustee herein and not in its individual
capacity, except as otherwise expressly provided in the Operative
Agreements.

            SECTION 6.7. Compensation. The Subordination Agent shall be
entitled to reasonable compensation, including expenses and disbursements,
for all services rendered hereunder and shall have a priority claim to the
extent set forth in Article III hereof on all monies collected hereunder
for the payment of such compensation, to the extent that such compensation
shall not be paid by others. The Subordination Agent agrees that it shall
have no right against any Trustee or Liquidity Provider or the Policy
Provider for any fee as compensation for its services as agent under this
Agreement. The provisions of this Section 6.7 shall survive the termination
of this Agreement.

            SECTION 6.8. May Become Certificateholder. The institution
acting as Subordination Agent hereunder may become a Certificateholder and
have all rights and benefits of a Certificateholder to the same extent as
if it were not the institution acting as the Subordination Agent.

            SECTION 6.9. Subordination Agent Required; Eligibility. There
shall at all times be a Subordination Agent hereunder which 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 the obligations
of which, whether now in existence or hereafter incurred, are fully and
unconditionally guaranteed by a corporation organized and doing business
under the laws of the United States of America, any State thereof or of the
District of Columbia and having a combined capital and surplus of at least
$100,000,000), if there is such an institution willing and able to perform
the duties of the Subordination Agent hereunder upon reasonable or
customary terms. Such corporation shall be a citizen of the United States
and shall be authorized under the laws of the United States or any State
thereof or of the District of Columbia to exercise corporate trust powers
and shall be subject to supervision or examination by federal, state or
District of Columbia authorities. If such corporation publishes reports of
condition at least annually, pursuant to law or to the requirements of any
of the aforesaid supervising or examining authorities, then, for the
purposes of this Section 6.9, 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.

            In case at any time the Subordination Agent shall cease to be
eligible in accordance with the provisions of this Section, the
Subordination Agent shall resign immediately in the manner and with the
effect specified in Section 8.1.

            SECTION 6.10. Money to Be Held in Trust. All Equipment Notes,
monies and other property deposited with or held by the Subordination Agent
pursuant to this Agreement shall be held in trust for the benefit of the
parties entitled to such Equipment Notes, monies and other property. All
such Equipment Notes, monies or other property shall be held in the Trust
Department of the institution acting as Subordination Agent hereunder.


                                ARTICLE VII

Section 6(b) of the Participation Agreements with respect to Owned
Aircraft, Section 6(c) of the Participation Agreements with respect to
Leased Aircraft and Section 7 of the Note Purchase Agreement. The
indemnities contained in such Sections of such agreements shall survive the
termination of this Agreement.


                                ARTICLE VIII

                       SUCCESSOR SUBORDINATION AGENT

            SECTION 8.1. Replacement of Subordination Agent; Appointment of
Successor. The Subordination Agent may resign at any time by so notifying
each Trustee, each Liquidity Provider and the Policy Provider. The
Controlling Party may remove the Subordination Agent for cause by so
notifying the Subordination Agent and may appoint a successor Subordination
Agent. The Controlling Party shall remove the Subordination Agent if:

          (1) the Subordination Agent fails to comply with Section 6.9
     hereof;

          (2) the Subordination Agent is adjudged bankrupt or insolvent;

          (3) a receiver or other public officer takes charge of the
     Subordination Agent or its property; or

          (4) the Subordination Agent otherwise becomes incapable of
     acting.

            If the Subordination Agent resigns or is removed or if a
vacancy exists in the office of Subordination Agent for any reason (the
Subordination Agent in such event being referred to herein as the retiring
Subordination Agent), the Controlling Party shall promptly appoint a
successor Subordination Agent.

            A successor Subordination Agent shall deliver (x) a written
acceptance of its appointment as Subordination Agent hereunder to the
retiring Subordination Agent and (y) a written assumption of its
obligations hereunder and under each Liquidity Facility and the Policy
Provider Agreement to each party hereto, upon which the resignation or
removal of the retiring Subordination Agent shall become effective, and the
successor Subordination Agent shall have all the rights, powers and duties
of the Subordination Agent under this Agreement. The successor
Subordination Agent shall mail a notice of its succession to the Liquidity
Providers, the Policy Provider and the Trustees. The retiring Subordination
Agent shall promptly transfer its rights under each of the Liquidity
Facilities and all of the property held by it as Subordination Agent to the
successor Subordination Agent.

            If a successor Subordination Agent does not take office within
60 days after the retiring Subordination Agent resigns or is removed, the
retiring Subordination Agent or one or more of the Trustees may petition
any court of competent jurisdiction for the appointment of a successor
Subordination Agent.

            If the Subordination Agent fails to comply with Section 6.9
hereof (to the extent applicable), one or more of the Trustees, one or more
of the Liquidity Providers or the Policy Provider may petition any court of
competent jurisdiction for the removal of the Subordination Agent and the
appointment of a successor Subordination Agent.

            Notwithstanding the foregoing, no resignation or removal of the
Subordination Agent shall be effective unless and until a successor has
been appointed. No appointment of a successor Subordination Agent shall be
effective unless and until the Rating Agencies shall have delivered a
Ratings Confirmation.

                                 ARTICLE IX

                         SUPPLEMENTS AND AMENDMENTS

            SECTION 9.1. Amendments, Waivers, etc. (a) This Agreement may
not be supplemented, amended or modified without the consent of each
Trustee (acting, except in the case of any amendment pursuant to Section
3.6(e)(v)(y) hereof with respect to any Replacement Liquidity Facility or
any amendment contemplated by the last sentence of this Section 9.1(a),
with the consent of holders of Certificates of the related Class evidencing
interests in the related Trust aggregating not less than a majority in
interest in such Trust or as otherwise authorized pursuant to the relevant
Trust Agreement), the Subordination Agent, each Liquidity Provider and the
Policy Provider; provided, however, that this Agreement may be
supplemented, amended or modified without the consent of (x) any Trustee if
such supplement, amendment or modification (i) is in accordance with
Section 9.1(c) hereof or (ii) cures an ambiguity or inconsistency or does
not materially adversely affect such Trustee or the holders of the related
Class of Certificates and (y) any Liquidity Provider and the Policy
Provider if such supplement, amendment or modification is in accordance
with Section 9.1(c) hereof; provided further, however, that, if such
supplement, amendment or modification (A) would (x) directly or indirectly
modify or supersede, or otherwise conflict with, Section 2.2(b), Section
3.6(e), Section 3.6(f) (other than the last sentence thereof), or the
second sentence of Section 10.6 or this Section 9.1 (collectively, the "US
Airways Provisions") or (y) otherwise adversely affect the interests of a
potential Replacement Liquidity Provider or of US Airways with respect to
its ability to replace any Liquidity Facility or with respect to its
payment obligations under any Operative Agreement or (B) is made pursuant
to the last sentence of this Section 9.1(a), then such supplement,
amendment or modification shall not be effective without the additional
written consent of US Airways. Notwithstanding the foregoing, without the
consent of each Certificateholder, each Liquidity Provider and the Policy
Provider, no supplement, amendment or modification of this Agreement may
(i) reduce the percentage of the interest in any Trust evidenced by the
Certificates issued by such Trust necessary to consent to modify or amend
any provision of this Agreement or to waive compliance therewith or (ii)
except as provided in the last sentence of this Section 9.1(a), modify
Section 2.4, 3.2 or 3.3 hereof, relating to the distribution of monies
received by the Subordination Agent hereunder from the Equipment Notes or
pursuant to the Liquidity Facilities or the Policy. Nothing contained in
this Section shall require the consent of a Trustee at any time following
the payment of Final Distributions with respect to the related Class of
Certificates. If the Replacement Liquidity Facility for any Liquidity
Facility in accordance with Section 3.6(e) hereof is to be comprised of
more than one instrument as contemplated by the definition of the term
"Replacement Liquidity Facility", then each of the parties hereto agrees to
amend this Agreement to incorporate appropriate mechanics for multiple
Liquidity Facilities for an individual Trust.

            (b) In the event that the Subordination Agent, as the
registered holder of any Equipment Notes, receives a request for its
consent to any amendment, modification, consent or waiver under such
Equipment Notes, the Indenture pursuant to which such Equipment Notes were
issued, or the related Lease, Participation Agreement or other related
document, (i) if no Indenture Default shall have occurred and be continuing
with respect to such Indenture, the Subordination Agent shall request
directions with respect to each Series of such Equipment Notes from the
Trustee of the Trust which holds such Equipment Notes and shall vote or
consent in accordance with the directions of such Trustee except that so
long as the Final Distributions on the Class G Certificates have not been
made or any Policy Provider Obligations remain outstanding (and no Policy
Provider Default shall have occurred and be continuing and so long as the
Policy Provider has endorsed the Policy (if so required) as provided in
Section 3.7(c) hereof), the Subordination Agent shall request directions
from the Policy Provider rather than the Class G Trustee with respect to
the Series G Equipment Notes held in the Class G Trust and shall vote or
consent in accordance with the directions of the Policy Provider, and (ii)
if any Indenture Default (which, in the case of any Indenture pertaining to
a Leased Aircraft, has not been cured by the applicable Owner Trustee or
the applicable Owner Participant, if applicable, pursuant to Section 4.03
of such Indenture) shall have occurred and be continuing with respect to
such Indenture, the Subordination Agent will exercise its voting rights as
directed by the Controlling Party, subject to Sections 4.1 and 4.4 hereof;
provided that no such amendment, modification or waiver shall, without the
consent of each Liquidity Provider and the Policy Provider, reduce the
amount of rent, supplemental rent or stipulated loss values payable by US
Airways under any Lease or reduce the amount of principal or interest
payable by US Airways under any Equipment Note issued under any Indenture
in respect of an Owned Aircraft.

            (c) Upon the issuance of the Class C Certificates, this
Agreement shall be amended by adding as a party hereto the Class C Trustee
and, if applicable, the Class C Liquidity Provider and the parties hereto
confirm and agree that upon the execution and delivery of any such
amendment by the Subordination Agent, the Class C Trustee and, if
applicable, the Class C Liquidity Provider, shall each be a party hereto as
fully and with the same force and effect as if each such Person had
originally executed and delivered a counterpart hereof. Any such amendment
shall amend the definitions of "Final Legal Distribution Date", "LTV Ratio"
and "Stated Interest Rate" to specify the applicable Final Legal
Distribution Date for the Class C Certificates, the applicable LTV Ratio
for the Class C Certificates and the applicable Stated Interest Rate for
the Class C Certificates, respectively, and to give effect to the
subordination of the Class C Certificates to the Class G Certificates and
to the Liquidity Obligations and to certain of the Policy Provider
Obligations, all to the extent and in the manner set forth herein, and any
such amendment shall make such further changes hereto as shall be
reasonably necessary to give effect thereto; provided, that no such
amendment shall materially adversely affect the Policy Provider. Upon the
presentation of any such amendment to the Subordination Agent, the
Subordination Agent agrees to execute the same and deliver a copy thereof
to each other party hereto and US Airways.

            SECTION 9.2. Subordination Agent Protected. If, in the
reasonable opinion of the institution acting as the Subordination Agent
hereunder, any document required to be executed pursuant to the terms of
Section 9.1 adversely affects any right, duty, immunity or indemnity with
respect to it under this Agreement, any Liquidity Facility or the Policy,
the Subordination Agent may in its discretion decline to execute such
document.

            SECTION 9.3. Effect of Supplemental Agreements. Upon the
execution of any amendment, consent or supplement hereto pursuant to the
provisions hereof, this Agreement shall be and be deemed to be and shall be
modified and amended in accordance therewith and the respective rights,
limitations of rights, obligations, duties and immunities under this
Agreement of the parties hereto and beneficiaries hereof shall thereafter
be determined, exercised and enforced hereunder subject in all respects to
such modifications and amendments, and all the terms and conditions of any
such supplemental agreement shall be and be deemed to be and shall be part
of the terms and conditions of this Agreement for any and all purposes. In
executing or accepting any supplemental agreement permitted by this Article
IX, the Subordination Agent shall be entitled to receive, and shall be
fully protected in relying upon, an opinion of counsel stating that the
execution of such supplemental agreement is authorized or permitted by this
Agreement.

            SECTION 9.4. Notice to Rating Agencies. Promptly following its
receipt of each amendment, consent, modification, supplement or waiver
contemplated by this Article IX, the Subordination Agent shall send a copy
thereof to each Rating Agency.

                               MISCELLANEOUS

provided that there shall then be no other amounts due to the
Certificateholders, the Trustees, the Liquidity Providers, the Policy
Provider and the Subordination Agent hereunder or under the Trust
Agreements, and that the commitment of (i) the Liquidity Providers under
the Liquidity Facilities and (ii) Policy Provider under the Policy shall
have expired or been terminated, this Agreement and the trusts created
hereby shall terminate and this Agreement shall be of no further force or
effect. Except as aforesaid or otherwise provided, this Agreement and the
trusts created hereby shall continue in full force and effect in accordance
with the terms hereof.

            SECTION 10.2. Intercreditor Agreement for Benefit of Trustees,
Liquidity Providers, the Policy Provider and Subordination Agent. Subject
to the second sentence of Section 10.6 and the provisions of Sections 4.4
and 9.1, nothing in this Agreement, whether express or implied, shall be
construed to give to any Person other than the Trustees, the Liquidity
Providers, the Policy Provider and the Subordination Agent any legal or
equitable right, remedy or claim under or in respect of this Agreement.

            SECTION 10.3. Notices. Unless otherwise expressly specified or

Whenever any notice in writing is required to be given by any Trustee,
Liquidity Provider, the Policy Provider or the Subordination Agent to any
of the other of them, such notice shall be deemed given and such
requirement satisfied when such notice is received unless received outside
of business hours, in which case on the open of business on the next
Business Day. A copy of any notice given by any Trustee, Liquidity Provider
or the Subordination Agent shall be given to the Policy Provider; provided
that the failure to do so shall not impair the validity of any such notice
or the Policy Provider's obligations hereunder and under the Policy. 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 parties to this
Agreement.

            SECTION 10.4. Severability. Any provision of this Agreement
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, and
any such prohibition or unenforceability in any jurisdiction shall not
invalidate or render unenforceable such provision in any other
jurisdiction.

            SECTION 10.5. No Oral Modifications or Continuing Waivers. No
terms or provisions of this Agreement 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 other party or other Person whose consent
is required pursuant to this Agreement and any waiver of the terms hereof
shall be effective only in the specific instance and for the specific
purpose given.

            SECTION 10.6. 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 assigns of each, all
as herein provided. In addition, the US Airways Provisions shall inure to
the benefit of US Airways and its successors and assigns, and (without
limitation of the foregoing) US Airways is hereby constituted, and agreed
to be, an express third party beneficiary of the US Airways Provisions.

            SECTION 10.7.  Headings.  The headings of the various
Articles and Sections herein and in the table of contents hereto
are for convenience of reference only and shall not define or limit
any of the terms or provisions hereof.

            SECTION 10.8. Counterpart Form. This 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 agreement.

            SECTION 10.9. Subordination. (a) As between the Liquidity
Providers and the Policy Provider, on the one hand, and the Trustees and
the Certificateholders, on the other hand, and as among the Trustees and
the related Certificateholders, this Agreement shall be a subordination
agreement for purposes of Section 510 of the United States Bankruptcy Code,
as amended from time to time.

            (b) Notwithstanding the provisions of this Agreement, if prior
to the payment in full to (i) the Liquidity Providers of all Liquidity
Obligations then due and payable and (ii) the Policy Provider of all Policy
Provider Obligations then due and payable, any party hereto shall have
received any payment or distribution in respect of Equipment Notes or any
other amount under the Indentures or other Operative Agreements which, had
the subordination provisions of this Agreement been properly applied to
such payment, distribution or other amount, would not have been distributed
to such Person, then such payment, distribution or other amount shall be
received and held in trust by such Person and paid over or delivered to the
Subordination Agent for application as provided herein.

            (c) If any Trustee, any Liquidity Provider, the Policy Provider
or the Subordination Agent receives any payment in respect of any
obligations owing hereunder (or, in the case of the Liquidity Providers or
the Policy Provider, in respect of the Liquidity Obligations or the Policy
Provider Obligations, as the case may be), which is subsequently
invalidated, declared preferential, set aside and/or required to be repaid
to a trustee, receiver or other party, then, to the extent of such payment,
such obligations (or, in the case of the Liquidity Providers or the Policy
Provider, such Liquidity Obligations or Policy Provider Obligations, as the
case may be) intended to be satisfied shall be revived and continue in full
force and effect as if such payment had not been received.

            (d) The Trustees (on behalf of themselves and the holders of
Certificates), the Liquidity Providers, the Policy Provider and the
Subordination Agent confirm that the payment priorities specified in
Sections 2.4, 3.2 and 3.3 shall apply in all circumstances, notwithstanding
the fact that the obligations owed to the Trustees and the holders of
Certificates are secured by certain assets and the Liquidity Obligations
and the Policy Provider Obligations may not be so secured. The Trustees
expressly agree (on behalf of themselves and the holders of Certificates)
not to assert priority over the holders of Liquidity Obligations or the
Policy Provider Obligations (except as specifically set forth in Section
2.4, 3.2 or 3.3) due to their status as secured creditors in any
bankruptcy, insolvency or other legal proceeding.

            (e) Each of the Trustees (on behalf of themselves and the
holders of Certificates), the Liquidity Providers, the Policy Provider and
the Subordination Agent may take any of the following actions without
impairing its rights under this Agreement:

            (i) obtain a Lien on any property to secure any amounts owing
      to it hereunder, including, in the case of the Liquidity Providers
      and the Policy Provider, the Liquidity Obligations or the Policy
      Provider Obligations, as the case may be,

            (ii) obtain the primary or secondary obligation of any other
      obligor with respect to any amounts owing to it hereunder, including,
      in the case of the Liquidity Providers and the Policy Provider, any
      of the Liquidity Obligations or the Policy Provider Obligations, as
      the case may be,

            (iii) renew, extend, increase, alter or exchange any amounts
      owing to it hereunder, including, in the case of the Liquidity
      Providers and the Policy Provider, any of the Liquidity Obligations
      or the Policy Provider Obligations, as the case may be, or release or
      compromise any obligation of any obligor with respect thereto,

            (iv)  refrain from exercising any right or remedy, or
      delay in exercising such right or remedy, which it may have,
      or

            (v)   take any other action which might discharge a
      subordinated party or a surety under applicable law;

provided, however, that the taking of any such actions by any of the
Trustees, the Liquidity Providers, the Policy Provider or the Subordination
Agent shall not prejudice the rights or adversely affect the obligations of
any other party under this Agreement.

            SECTION 10.10. Governing Law. THIS 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.

            SECTION 10.11.  Submission to Jurisdiction; Waiver of
Jury Trial; Waiver of Immunity.  (a)  Each of the parties hereto
hereby irrevocably and unconditionally:

            (i) submits for itself and its property in any legal action or
      proceeding relating to this Agreement or any other Operative
      Agreement, or for recognition and enforcement of any judgment in
      respect hereof or thereof, to the nonexclusive general jurisdiction
      of the courts of the State of New York, the courts of the United
      States of America for the Southern District of New York, and the
      appellate courts from any thereof;

            (ii) consents that any such action or proceeding may be brought
      in such courts, and waives any objection that it may now or hereafter
      have to the venue of any such action or proceeding in any such court
      or that such action or proceeding was brought in an inconvenient
      court and agrees not to plead or claim the same;

            (iii) agrees that service of process in any such action or
      proceeding may be effected by mailing a copy thereof by registered or
      certified mail (or any substantially similar form of mail), postage
      prepaid, to each party hereto at its address set forth in Section
      10.3 hereof, or at such other address of which the other parties
      shall have been notified pursuant thereto; and

            (iv) agrees that nothing herein shall affect the right to
      effect service of process in any other manner permitted by law or
      shall limit the right to sue in any other jurisdiction.

            (b) EACH OF THE PARTIES HERETO HEREBY AGREES TO WAIVE ITS
RESPECTIVE RIGHTS TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION BASED
UPON OR ARISING OUT OF THIS AGREEMENT OR ANY DEALINGS BETWEEN THEM RELATING
TO THE SUBJECT MATTER OF THIS AGREEMENT AND THE RELATIONSHIP THAT IS BEING
ESTABLISHED, including, without limitation, contract claims, tort claims,
breach of duty claims and all other common law and statutory claims. Each
of the parties warrants and represents that it has reviewed this waiver
with its legal counsel, and that it knowingly and voluntarily waives its
jury trial rights following consultation with such legal counsel. THIS
WAIVER IS IRREVOCABLE, AND CANNOT BE MODIFIED EITHER ORALLY OR IN WRITING,
AND THIS WAIVER SHALL APPLY TO ANY SUBSEQUENT AMENDMENTS, RENEWALS,
SUPPLEMENTS OR MODIFICATIONS TO THIS AGREEMENT.

            (c) Each Liquidity Provider hereby waives any immunity it may
have from the jurisdiction of the courts of the United States of America or
of any State and waives any immunity any of its properties located in the
United States of America may have from attachment or execution upon a
judgment entered by any such court under the United States Foreign
Sovereign Immunities Act of 1976 or any similar successor legislation.



            IN WITNESS WHEREOF, the parties hereto have caused this
Agreement to be duly executed by their respective officers thereunto duly
authorized, as of the day and year first above written.

set forth in this Agreement;

irrevocably instruct the Escrow Agent, and the Escrow Agent agrees: (a) to
enter into the Deposit Agreement and, if requested by the Company pursuant
to Section 5(a)(vii) of the Note Purchase Agreement, to enter into a
Replacement Deposit Agreement with the Replacement Depositary specified by
the Company; (b) to appoint the Paying Agent as provided in this Agreement;

Distribution Date, all accrued and unpaid interest on such Deposits to but
excluding the Replacement Withdrawal Date, and (Y) direct the Depositary to
transfer such Deposits on behalf of the Escrow Agent to the Replacement
Depositary in accordance with the Replacement Deposit Agreement and (e) if
there are any undrawn Deposits (as defined in the Deposit Agreement) on the
"Termination Date", which shall mean the earlier of (i) February 7, 2001
(or June 7, 2001 if all the Equipment Notes under the Note Purchase
Agreement have not been purchased by February 7, 2001 on account of
manufacturing delays that occur for reasons beyond the control of US
Airways and that are not occasioned by US Airways' fault or negligence) and
(ii) the day on which the Escrow Agent receives notice from the Pass
Through Trustee that the Pass Through Trustee's obligation to purchase
Equipment Notes under the Note Purchase Agreement has terminated, to give
notice to the Depositary (with a copy to the Paying Agent) substantially in
the form of Exhibit B to the Deposit Agreement requesting a withdrawal of
all of the remaining Deposits, together with accrued and unpaid interest on
such Deposits to the date of withdrawal, on the 15th day after the date
that such notice of withdrawal is given to the Depositary (or, if not a
Business Day, on the next succeeding Business Day) (a "Final Withdrawal"),
provided that if the day scheduled for the Final Withdrawal in accordance
with the foregoing is within ten days before or after a Regular
Distribution Date, then the Escrow Agent shall request that such requested
Final Withdrawal be made on such Regular Distribution Date (the date of
such requested withdrawal, the "Final Withdrawal Date"). If for any reason
the Escrow Agent shall have failed to give the Final Withdrawal Notice to
the Depositary on or before February 8, 2001 (or June 8, 2001 if all the
Equipment Notes under the Note Purchase Agreement have not been purchased
by February 7, 2001 on account of manufacturing delays that occur for
reasons beyond the control of US Airways and that are not occasioned by US
Airways' fault or negligence), and there are unwithdrawn Deposits on such
date, the Final Withdrawal Date shall be deemed to be February 23, 2001 (or
June 25, 2001 if all the Equipment Notes under the Note Purchase Agreement
have not been purchased by February 7, 2001 on account of manufacturing
delays that occur for reasons beyond the control of US Airways and that are
not occasioned by US Airways' fault or negligence).

     The Escrow Agent hereby directs the Underwriters to, and the
Underwriters hereby acknowledge that on the date hereof they shall,
irrevocably deliver to the Depositary on behalf of the Escrow Agent, an
amount in U.S. dollars ("Dollars") and immediately available funds equal to
$281,678,000 for deposit on behalf of the Escrow Agent with the Depositary
in accordance with Section 2.1 of the Deposit Agreement. The Underwriters
hereby instruct the Escrow Agent, upon the Depositary's receipt (on behalf
of the Escrow Agent) of such sum from the Underwriters, to confirm such
receipt by executing and delivering to the Pass Through Trustee an Escrow
Receipt in the form of Exhibit A hereto (an "Escrow Receipt"), (a) to be
affixed by the Pass Through Trustee to each Certificate and (b) to evidence
the same percentage interest (the "Escrow Interest") in the Account Amounts
(as defined below) as the Fractional Undivided Interest in the Pass Through
Trust evidenced by the Certificate to which it is to be affixed. The Escrow
Agent shall provide to the Pass Through Trustee for attachment to each
Certificate newly issued under and in accordance with the Pass Through
Trust Agreement an executed Escrow Receipt as the Pass Through Trustee may
from time to time request of the Escrow Agent. Each Escrow Receipt shall be
registered by the Escrow Agent in a register (the "Register") maintained by
the Escrow Agent in the same name and same manner as the Certificate to
which it is attached and may not thereafter be detached from such
Certificate to which it is to be affixed prior to the distribution of the
Final Withdrawal (the "Final Distribution"). After the Final Distribution,
no additional Escrow Receipts shall be issued and the Pass Through Trustee
shall request the return to the Escrow Agent for cancellation of all
outstanding Escrow Receipts.

     All payments and distributions made to holders of an Escrow Receipt
(collectively "Receiptholders") in respect of the Escrow Receipt shall be
made only from amounts deposited in the Paying Agent Account (as defined
below) ("Account Amounts"). Each Receiptholder, by its acceptance of an
Escrow Receipt, agrees that (a) it will look solely to the Account Amounts
for any payment or distribution due to such Receiptholder pursuant to the
terms of the Escrow Receipt and this Agreement and (b) it will have no
recourse to US Airways, the Pass Through Trustee, the Paying Agent or the
Escrow Agent, except as expressly provided herein or in the Pass Through
Trust Agreement. No Receiptholder shall have any right to vote or in any
manner otherwise control the operation and management of the Paying Agent
Account or the obligations of the parties hereto, nor shall anything set
forth herein, or contained in the terms of the Escrow Receipt, be construed
so as to constitute the Receiptholders from time to time as partners or
members of an association.

     If (a) any mutilated Escrow Receipt is surrendered to the Escrow Agent
or the Escrow Agent receives evidence to its satisfaction of the
destruction, loss or theft of any Escrow Receipt and (b) there is delivered
to the Escrow Agent and the Pass Through Trustee such security, indemnity
or bond, as may be required by them to hold each of them harmless, then,
absent notice to the Escrow Agent or the Pass Through Trustee that such
destroyed, lost or stolen Escrow Receipt has been acquired by a bona fide
purchaser, and provided that the requirements of Section 8-405 of the
Uniform Commercial Code in effect in any applicable jurisdiction are met,
the Escrow Agent shall execute, authenticate and deliver, in exchange for
or in lieu of any such mutilated, destroyed, lost or stolen Escrow Receipt,
a new Escrow Receipt or Escrow Receipts and of like Escrow Interest in the
Account Amounts and bearing a number not contemporaneously outstanding.

     In connection with the issuance of any new Escrow Receipt under this
Section 1.5, the Escrow Agent may require the payment of a sum sufficient
to cover any tax or other governmental charge that may be imposed in
relation thereto and any other expenses (including the fees and expenses of
the Pass Through Trustee and the Escrow Agent) connected therewith.

     Any duplicate Escrow Receipt issued pursuant to this Section 1.5 shall
constitute conclusive evidence of the appropriate Escrow Interest in the
Account Amounts, as if originally issued, whether or not the lost, stolen
or destroyed Escrow Receipt shall be found at any time.

     The provisions of this Section 1.5 are exclusive and shall preclude
(to the extent lawful) all other rights and remedies with respect to the
replacement or payment of mutilated, destroyed, lost or stolen Escrow
Receipts.

     On the date of any Purchase Withdrawal, the Pass Through Trustee may
re-deposit with the Depositary some or all of the amounts so withdrawn in
accordance with Section 2.4 of the Deposit Agreement.

     Subject to the appointment and acceptance of a successor Escrow Agent
as provided below, the Escrow Agent may resign at any time by giving thirty
(30) days' prior written notice thereof to the Investors, but may not
otherwise be removed except for cause by the written consent of the
Investors with respect to Investors representing Escrow Interests
aggregating not less than a majority in interest in the Account Amounts (an
"Action of Investors"). Upon any such resignation or removal, the
Investors, by an Action of Investors, shall have the right to appoint a
successor Escrow Agent. If no successor Escrow Agent shall have been so
appointed and shall have accepted such appointment within thirty (30) days
after the retiring Escrow Agent's giving of notice of resignation or the
removal of the retiring Escrow Agent, then the retiring Escrow Agent may
appoint a successor Escrow Agent. Any successor Escrow Agent shall be a
bank which has an office in the United States with a combined capital and
surplus of at least $100,000,000. Upon the acceptance of any appointment as
Escrow Agent hereunder by a successor Escrow Agent, such successor Escrow
Agent shall enter into such documents as the Pass Through Trustee shall
require and shall thereupon succeed to and become vested with all the
rights, powers, privileges and duties of the retiring Escrow Agent, and the
retiring Escrow Agent shall be discharged from its duties and obligations
hereunder. No resignation or removal of the Escrow Agent shall be effective
unless a written confirmation shall have been obtained from each of Moody's
Investors Service, Inc. and Standard & Poor's Rating Services, a division
of The McGraw-Hill Companies, Inc., that the replacement of the Escrow
Agent with the successor Escrow Agent will not result in (a) a reduction of
the rating for the Certificates below the then current rating for the
Certificates or (b) a withdrawal or suspension of the rating of the
Certificates.

     Prior to due presentment of a Certificate for registration of
transfer, the Escrow Agent and the Paying Agent may treat the Person in
whose name any Escrow Receipt is registered (as of the day of
determination) as the owner of such Escrow Receipt for the purpose of
receiving distributions pursuant to this Agreement and for all other
purposes whatsoever, and neither the Escrow Agent nor the Paying Agent
shall be affected by any notice to the contrary.

     The Escrow Agent agrees to take such actions, and execute such other
documents, as may be reasonably requested by the Pass Through Trustee in
order to effectuate the purposes of this Agreement and the performance by
the Escrow Agent of its obligations hereunder.

     SECTION 2. Paying Agent.
                ------------

     Section 2.1 Appointment of Paying Agent. The Escrow Agent hereby
irrevocably appoints and authorizes the Paying Agent to act as its paying
agent hereunder, for the benefit of the Investors, for such specific
purposes and with such powers as are specifically delegated to the Paying
Agent by the terms of this Agreement, together with such other powers as
are reasonably incidental thereto. Any and all money received and held by
the Paying Agent under this Agreement or the Deposit Agreement shall be
held in the Paying Agent Account for the benefit of the Investors. The
Paying Agent (which term as used in this sentence shall include reference
to its affiliates and its own and its affiliates' officers, directors,
employees and agents):

     (1) shall have no duties or responsibilities except those expressly
set forth in this Agreement, and shall not by reason of this Agreement be a
trustee for the Escrow Agent;

     (2) shall not be responsible to the Escrow Agent for any recitals,
statements, representations or warranties of any person other then itself
contained in this Agreement or for the failure by the Escrow Agent or any
other person or entity (other than the Paying Agent) to perform any of its
obligations hereunder (whether or not the Paying Agent shall have any
knowledge thereof); and

     (3) shall not be responsible for any action taken or omitted to be
taken by it hereunder or provided for herein or in connection herewith,
except for its own willful misconduct or gross negligence (or simple
negligence in connection with the handling of funds).

     The Paying Agent shall establish a deposit account (the "Paying Agent
Account") at State Street Bank and Trust Company of Connecticut, National
Association in the name of the Escrow Agent. It is expressly understood by
the parties hereto that the Paying Agent is acting as the paying agent of
the Escrow Agent hereunder and that no amounts on deposit in the Paying
Agent Account constitute part of the Trust Property.

     The Escrow Agent hereby irrevocably instructs the Paying Agent, and
the Paying Agent agrees to act, as follows:

     (1) On each Interest Payment Date (as defined in the Deposit
Agreement) or as soon thereafter as the Paying Agent has confirmed receipt
in the Paying Agent Account from the Depositary of any amount in respect of
accrued interest on the Deposits, the Paying Agent shall distribute out of
the Paying Agent Account the entire amount deposited therein by the
Depositary. There shall be so distributed to each Receiptholder of record
on the 15th day (whether or not a Business Day) preceding such Interest
Payment Date by check mailed to such Receiptholder, at the address
appearing in the Register, such Receiptholder's pro rata share (based on
the Escrow Interest in the Account Amounts held by such Receiptholder) of
the total amount of interest deposited by the Depositary in the Paying
Agent Account on such date, except that, with respect to Escrow Receipts
registered on the Record Date in the name of The Depository Trust Company,
a New York corporation ("DTC"), such distribution shall be made by wire
transfer in immediately available funds to the account designated by DTC.

     (2) Upon the confirmation by the Paying Agent of receipt in the Paying
Agent Account from the Depositary of any amount in respect of the Final
Withdrawal, the Paying Agent shall forthwith distribute the entire amount
of the Final Withdrawal deposited therein by the Depositary. There shall be
so distributed to each Receiptholder of record on the 15th day (whether or
not a Business Day) preceding the Final Withdrawal Date by check mailed to
such Receiptholder, at the address appearing in the Register, such
Receiptholder's pro rata share (based on the Escrow Interest in the Account
Amounts held by such Receiptholder) of the total amount in the Paying Agent
Account on account of such Final Withdrawal, except that, with respect to
Escrow Receipts registered on the Record Date in the name of DTC, such
distribution shall be made by wire transfer in immediately available funds
to the account designated by DTC.

     (3) If any payment of interest or principal in respect of the Final
Withdrawal is not received by the Paying Agent within five (5) days of the
applicable date when due, then it shall be distributed to Receiptholders
after actual receipt by the Paying Agent on the same basis as a Special
Payment is distributed under the Pass Through Trust Agreement.

     (4) The Paying Agent shall include with any check mailed pursuant to
this Section any notice required to be distributed under the Pass Through
Trust Agreement that is furnished to the Paying Agent by the Pass Through
Trustee.

     The Paying Agent shall exclude and withhold from each distribution of
accrued interest on the Deposits (as defined in the Deposit Agreement) and
any amount in respect of the Final Withdrawal any and all withholding taxes
applicable thereto as required by law. The Paying Agent agrees to act as
such withholding agent and, in connection therewith, whenever any present
or future taxes or similar charges are required to be withheld with respect
to any amounts payable in respect of the Deposits (as defined in the
Deposit Agreement) or the escrow amounts, to withhold such amounts and
timely pay the same to the appropriate authority in the name of and on
behalf of the Receiptholders, 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 Receiptholder appropriate
documentation showing the payment thereof, together with such additional
documentary evidence as such Receiptholder may reasonably request from time
to time. The Paying Agent agrees to file any other information reports as
it may be required to file under United States law.

     Subject to the appointment and acceptance of a successor Paying Agent
as provided below, the Paying Agent may resign at any time by giving thirty
(30) days' prior written notice thereof to the Escrow Agent, but may not
otherwise be removed except for cause by the Escrow Agent. Upon any such
resignation or removal, the Escrow Agent shall have the right to appoint a
successor Paying Agent. If no successor Paying Agent shall have been so
appointed and shall have accepted such appointment within thirty (30) days
after the retiring Paying Agent's giving of notice of resignation or the
removal of the retiring Paying Agent, then the retiring Paying Agent may
appoint a successor Paying Agent. Any Successor Paying Agent shall be a
bank which has an office in the United States with a combined capital and
surplus of at least US$100,000,000. Upon the acceptance of any appointment
as Paying Agent hereunder by a successor Paying Agent, such successor
Paying Agent shall enter into such documents as the Escrow Agent shall
require and shall thereupon succeed to and become vested with all the
rights, powers, privileges and duties of the retiring Paying Agent, and the
retiring Paying Agent shall be discharged from its duties and obligations
hereunder.

     Promptly after receipt by the Paying Agent of notice that the Escrow
Agent has requested a Final Withdrawal or that a Final Withdrawal will be
made, the Paying Agent shall cause notice of the distribution of the Final
Withdrawal to be mailed to each of the Receiptholders at its address as it
appears in the Register. Such notice shall be mailed not less than fifteen
(15) days prior to the Final Withdrawal Date. Such notice shall set forth:

     (1) the Final Withdrawal Date and the date for determining
Receiptholders of record who shall be entitled to receive distributions in
respect of the Final Withdrawal;

     (2) the amount of the payment in respect of the Final Withdrawal for
each $1,000 face amount Certificate (based on information provided by the
Pass Through Trustee) and the amount thereof constituting unused Deposits
(as defined in the Deposit Agreement) and interest thereon; and

     (3) if the Final Withdrawal Date is the same date as a Regular
Distribution Date, the total amount to be received on such date for each
$1,000 face amount Certificate (based on information provided by the Pass
Through Trustee).

     Such mailing may include any notice required to be given to
Certificateholders in connection with such distribution pursuant to the
Pass Through Trust Agreement.

     If, notwithstanding the instructions in Article IV of the Deposit
Agreement that all amounts payable to the Escrow Agent under the Deposit
Agreement be paid by the Depositary directly to the Paying Agent or the
Pass Through Trustee (depending on the circumstances), the Escrow Agent
receives any payment thereunder, then the Escrow Agent shall forthwith pay
such amount in Dollars and in immediately available funds by wire transfer
to (a) in the case of a payment of accrued interest on the Deposits (as
defined in the Deposit Agreement) or any Final Withdrawal, directly to the
Paying Agent Account, (b) in the case of any Purchase Withdrawal, directly
to the Pass Through Trustee or its designee as specified and in the manner
provided in the Applicable Notice of Purchase Withdrawal and (c) in the
case of any Replacement Withdrawal (other than accrued interest), to the
Replacement Depositary as provided in the Replacement Deposit Agreement.
The Escrow Agent hereby waives any and all rights of set-off, combination
of accounts, right of retention or similar right (whether arising under
applicable law, contract or otherwise) it may have against amounts payable
to the Paying Agent howsoever arising.

     The Escrow Agent shall take such other actions under or in respect of
the Deposit Agreement (including, without limitation, the enforcement of
the obligations of the Depositary thereunder) as the Investors, by an
Action of Investors, may from time to time request.

     The Escrow Agent represents and warrants to US Airways, the Investors,
the Paying Agent and the Pass Through Trustee as follows:

     (1) it is a national banking association duly organized and validly
existing in good standing under the laws of the United States of America;

     (2) it has full power, authority and legal right to conduct its
business and operations as currently conducted and to enter into and
perform its obligations under this Agreement, the Deposit Agreement and any
Replacement Deposit Agreement;

     (3) the execution, delivery and performance of each of this Agreement,
the Deposit Agreement and any Replacement Deposit Agreement have been duly
authorized by all necessary corporate action on the part of it and do not
require any stockholder approval, or approval or consent of any trustee or
holder of any indebtedness or obligations of it, and each such document has
been duly executed and delivered by it and constitutes its legal, valid and
binding obligations enforceable against it in accordance with the terms
hereof or thereof except as such enforceability may be limited by
bankruptcy, insolvency, moratorium, reorganization or other similar laws or
equitable principles of general application to or affecting the enforcement
of creditors' rights generally (regardless of whether such enforceability
is considered in a proceeding in equity or at law);

     (4) no authorization, consent or approval of or other action by, and
no notice to or filing with, any United States federal or state
governmental authority or regulatory body is required for the execution,
delivery or performance by it of this Agreement or the Deposit Agreement or
any Replacement Deposit Agreement;

     (5) neither the execution, delivery or performance by it of this
Agreement or the Deposit Agreement or any Replacement Deposit Agreement,
nor compliance with the terms and provisions hereof or thereof, conflicts
or will conflict with or results or will result in a breach or violation of
any of the terms, conditions or provisions of, or will require any consent
or approval under, any law, governmental rule or regulation or the charter
documents, as amended, or bylaws, as amended, of it or any similar
instrument binding on it or any order, writ, injunction or decree of any
court or governmental authority against it or by which it or any of its
properties is bound or any indenture, mortgage or contract or other
agreement or instrument to which it is a party or by which it or any of its
properties is bound, or constitutes or will constitute a default thereunder
or results or will result in the imposition of any lien upon any of its
properties; and

     (6) there are no pending or, to its knowledge, threatened actions,
suits, investigations or proceedings (whether or not purportedly on behalf
of it) against or affecting it or any of its property before or by any
court or administrative agency which, if adversely determined, (A) would
adversely affect the ability of it to perform its obligations under this
Agreement or the Deposit Agreement or any Replacement Deposit Agreement or
(B) would call into question or challenge the validity of this Agreement or
the Deposit Agreement or the enforceability hereof or thereof in accordance
with the terms hereof or thereof, nor is the Escrow Agent in default with
respect to any order of any court, governmental authority, arbitration
board or administrative agency so as to adversely affect its ability to
perform its obligations under this Agreement or the Deposit Agreement.

     The Paying Agent represents and warrants to US Airways, the Investors,
the Escrow Agent and the Pass Through Trustee as follows:

     (1) it is a national banking association duly organized and validly
existing in good standing under the laws of the United States of America;

     (2) it has full power, authority and legal right to conduct its
business and operations as currently conducted and to enter into and
perform its obligations under this Agreement;

     (3) the execution, delivery and performance of this Agreement has been
duly authorized by all necessary corporate action on the part of it and
does not require any stockholder approval, or approval or consent of any
trustee or holder of any indebtedness or obligations of it, and such
document has been duly executed and delivered by it and constitutes its
legal, valid and binding obligations enforceable against it in accordance
with the terms hereof except as such enforceability may be limited by
bankruptcy, insolvency, moratorium, reorganization or other similar laws or
equitable principles of general application to or affecting the enforcement
of creditors' rights generally (regardless of whether such enforceability
is considered in a proceeding in equity or at law);

     (4) no authorization, consent or approval of or other action by, and
no notice to or filing with, any United States federal or state
governmental authority or regulatory body is required for the execution,
delivery or performance by it of this Agreement;

     (5) neither the execution, delivery or performance by it of this
Agreement, nor compliance with the terms and provisions hereof, conflicts
or will conflict with or results or will result in a breach or violation of
any of the terms, conditions or provisions of, or will require any consent
or approval under, any law, governmental rule or regulation or the charter
documents, as amended, or bylaws, as amended, of it or any similar
instrument binding on it or any order, writ, injunction or decree of any
court or governmental authority against it or by which it or any of its
properties is bound or any indenture, mortgage or contract or other
agreement or instrument to which it is a party or by which it or any of its
properties is bound, or constitutes or will constitute a default thereunder
or results or will result in the imposition of any lien upon any of its
properties; and

     (6) there are no pending or, to its knowledge, threatened actions,
suits, investigations or proceedings (whether or not purportedly on behalf
of it) against or affecting it or any of its property before or by any
court or administrative agency which, if adversely determined, (A) would
adversely affect the ability of it to perform its obligations under this
Agreement or (B) would call into question or challenge the validity of this
Agreement or the enforceability hereof in accordance with the terms hereof,
nor is the Paying Agent in default with respect to any order of any court,
governmental authority, arbitration board or administrative agency so as to
adversely affect its ability to perform its obligations under this
Agreement.

     Except for actions expressly required of the Escrow Agent or the
Paying Agent hereunder, each of the Escrow Agent and the Paying Agent shall
in all cases be fully justified in failing or refusing to act hereunder
unless it shall have been indemnified by the party requesting such action
in a manner reasonably satisfactory to it against any and all liability and
expense which may be incurred by it by reason of taking or continuing to
take any such action. In the event US Airways requests any amendment to any
Operative Document (as defined in the Note Purchase Agreement), the Pass
Through Trustee agrees to pay all reasonable fees and expenses (including,
without limitation, fees and disbursements of counsel) of the Escrow Agent
and the Paying Agent in connection therewith.

     Upon request of the Pass Through Trustee and approval by an Action of
Investors, the Escrow Agent shall enter into an amendment to this
Agreement, so long as such amendment does not adversely affect the rights
or obligations of the Escrow Agent or the Paying Agent, provided that upon
request of the Pass Through Trustee and without any consent of the
Investors, the Escrow Agent shall enter into an amendment to this Agreement
for any of the following purposes:

     (1) to correct or supplement any provision in this Agreement which may
be defective or inconsistent with any other provision herein or to cure any
ambiguity or correct any mistake or to modify any other provision with
respect to matters or questions arising under this Agreement, provided that
any such action shall not materially adversely affect the interests of the
Investors; or

     (2) to comply with any requirement of the SEC, applicable law, rules
or regulations of any exchange or quotation system on which the
Certificates are listed or any regulatory body; or

     (3) to evidence and provide for the acceptance of appointment under
this Agreement of a successor Escrow Agent, successor Paying Agent or
successor Pass Through Trustee.

     Unless otherwise expressly provided herein, any notice or other
communication under this Agreement shall be in writing (including by
facsimile) and shall be deemed to be given and effective upon receipt
thereof. All notices shall be sent to (a) in the case of the Investors, as

execution of this Agreement, the Pass Through Trustee has delivered to the
Escrow Agent a certificate containing specimen signatures of the
representatives of the Pass Through Trustee who are authorized to give

may conclusively rely on such certificate until the Escrow Agent receives
written notice from the Pass Through Trustee to the contrary.

     No party hereto shall be entitled to assign or otherwise transfer this
Agreement (or any interest herein) other than (in the case of the Escrow
Agent) to a successor escrow agent under Section 1.7 hereof or (in the case
of the Paying Agent) to a successor paying agent under Section 2.5 hereof,
and any purported assignment in violation thereof shall be void. This
Agreement shall be binding upon the parties hereto and their respective
successors and (in the case of the Escrow Agent and the Paying Agent) their
respective permitted assigns.

     This Agreement sets forth all of the promises, covenants, agreements,
conditions and understandings among the Escrow Agent, the Paying Agent, the

     This Agreement may be executed in one or more counterparts, all of
which taken together shall constitute one instrument.

     SECTION 15. Subrogation and Third Party Beneficiary. To the extent
that the Policy Provider makes any payment under the Policy in respect of
an Escrow Receipt as a result of the Depositary's failure to make a
scheduled interest payment on a Deposit to the Paying Agent Account, the
Policy Provider shall be subrogated to the rights of the holder of such
Escrow Receipt in respect thereof to the extent of such payment. The Policy
Provider shall be an express third party beneficiary of this Section 15 to
the extent necessary to enforce such rights of subrogation.


     IN WITNESS WHEREOF, the Escrow Agent, the Paying Agent, the
Underwriters and the Pass Through Trustee have caused this Escrow and
Paying Agent Agreement (Class G) to be duly executed as of the day and year
first above written.

in amounts ("Account Amounts") from time to time deposited into a certain
paying agent account (the "Paying Agent Account") described in the Escrow
and Paying Agent Agreement (Class G) dated as of March 3, 2000 (as amended,

Credit Suisse First Boston Corporation, as Underwriters, State Street Bank
and Trust Company of Connecticut, National Association, as Pass Through

together with its successors in such capacity, the "Paying Agent").

By virtue of its acceptance hereof the holder of this Escrow Receipt
assents and agrees to be bound by the provisions of the Escrow and Paying
Agent Agreement and this Escrow Receipt.

            This Escrow Receipt represents a fractional undivided interest
in amounts deposited from time to time in the Paying Agent Account, and
grants or represents no rights, benefits or interests of any kind in
respect of any assets or property other than such amounts. This Escrow

Agreement or in the Pass Through Trust Agreement. No Receiptholder of this
Escrow Receipt shall have any right to vote or in any manner otherwise
control the operation and management of the Paying Agent Account, nor shall
anything set forth herein, or contained in the terms of this Escrow
Receipt, be construed so as to constitute the Receiptholders from time to
time as partners or members of an association.

            This Escrow Receipt may not be assigned or transferred except
in connection with the assignment or transfer of the Certificate to which
this Escrow Receipt is affixed. After payment to the holder hereof of its
Escrow Interest in the Final Distribution, upon the request of the Pass
Through Trustee, the holder hereof will return this Escrow Receipt to the
Pass Through Trustee.

            The Paying Agent may treat the person in whose name the
Certificate to which this Escrow Receipt is attached as the owner hereof
for all purposes, and the Paying Agent shall not be affected by any notice
to the contrary.

            THIS ESCROW RECEIPT SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.


            IN WITNESS WHEREOF, the Escrow Agent has caused this Escrow
Receipt to be duly executed.

the Rating Agencies not less than two (2) Business Day's prior notice (a
"Closing Notice") of the scheduled closing date (the "Scheduled Closing
Date") (or, in the case of a Substitute Closing Notice under Section 2(f)
or (g) hereof, one (1) Business Day's prior notice) of a financing in
respect of each New Aircraft, which notice shall:

                           (i)  specify whether the Company has elected
      to treat such New Aircraft as a Leased Aircraft or an Owned Aircraft;

                           (ii)  specify the Scheduled Closing Date on
      which the financing therefor in the manner provided herein shall be
      consummated, which Scheduled Closing Date shall be within 120 days of
      the delivery of such New Aircraft from the Seller to the Company or
      Group (or, with Rating Agency Confirmation, a longer period following
      delivery of such New Aircraft from Seller to the Company or Group,
      but in no event on or after the Cut-Off Date) and prior to the
      Cut-Off Date;

                           (iii)  instruct the Pass Through Trustee to
      instruct the Escrow Agent to provide a Notice of Purchase Withdrawal
      to the Depositary with respect to the Series G Equipment Notes to be
      issued in connection with the financing of such New Aircraft;

                           (iv)  instruct the Pass Through Trustee to enter
      into the Participation Agreement included in the Financing Agreements
      with respect to such Aircraft in such form and at such a time on or
      before the Scheduled Closing Date specified in such Closing Notice
      and to perform its obligations thereunder;

                           (v)  specify the aggregate principal amount of
      Series G Equipment Notes to be issued, and purchased by the Pass
      Through Trustee, in connection with the financing of such New
      Aircraft on such Scheduled Closing Date (which shall in all respects
      comply with the Mandatory Economic Terms); and

                           (vi)  if such New Aircraft is to be a Leased
      Aircraft, certify that the related Owner Participant (A) is not an
      Affiliate of the Company and (B) based on the representations of such
      Owner Participant, is either (1) a Qualified Owner Participant or (2)
      any other person the obligations of which under the Owner Participant
      Documents (as defined in the applicable Participation Agreement) are
      guaranteed by a Qualified Owner Participant.

Notwithstanding the foregoing, in the event the Scheduled Closing Date for
any Aircraft to be financed pursuant to the terms hereof is on or within 3
Business Days following the date of issuance of the Certificates, the
Closing Notice therefor may be delivered to the parties hereto on such
Scheduled Closing Date.

                  (c) Upon receipt of a Closing Notice, the Pass Through
Trustee shall, and shall cause the Subordination Agent to, enter into and
perform their obligations under the Participation Agreement specified in
such Closing Notice, provided, however, that such Participation Agreement
and the other Financing Agreements to be entered into pursuant to such
Participation Agreement shall be in the forms thereof annexed hereto in all
material respects with such changes therein as shall have been requested by
the Company or the related Owner Participant (in the case of Lease
Financing Agreements), and agreed to by the Company and, if modified in any
material respect, as to which prior written consent of the Policy Provider
shall have been obtained and as to which Rating Agency Confirmation shall
have been obtained from each Rating Agency by the Company (to be delivered
by the Company to the Pass Through Trustee and the Policy Provider on or
before the relevant Closing Date, it being understood that if Policy
Provider consent and Rating Agency Confirmation shall have been received
with respect to any Financing Agreements and such Financing Agreements are
utilized for subsequent New Aircraft (or Substitute Aircraft) without
material modifications, no additional Policy Provider consent or Rating
Agency Confirmation shall be required); provided, however, that the
relevant Financing Agreements as executed and delivered shall not vary the
Mandatory Economic Terms and shall contain the Mandatory Document Terms (as
such Mandatory Document Terms may be modified in accordance with Schedule V
hereto). Notwithstanding the foregoing, if any Financing Agreement annexed
hereto shall not have been reviewed by either Rating Agency prior to the
Issuance Date, then, prior to the use thereof in connection with the
financing of any Aircraft hereunder, the Company shall obtain from each
Rating Agency a confirmation that the use of such Financing Agreement would
not result in (A) a reduction of the rating for the Class G Certificates
below the then current rating for such Class of Certificates (without
regard to the Policy) or (B) a withdrawal or suspension of the rating of
the Class G Certificates, in each case, without regard to the Policy.

                  (d) With respect to each New Aircraft, the Company shall
cause State Street Bank and Trust Company of Connecticut, National
Association (or such other person that meets the eligibility requirements
to act as loan trustee under the Leased Aircraft Indenture or Owned
Aircraft Indenture) to execute as Loan Trustee the Financing Agreements
relating to such Aircraft to which such Loan Trustee is intended to be a
party, and shall concurrently therewith execute such Financing Agreements
to which the Company is intended to be a party and perform its respective
obligations thereunder. Upon the request of either Rating Agency or of the
Policy Provider, the Company shall deliver or cause to be delivered to each
Rating Agency or the Policy Provider, as the case may be, a true and
complete copy of each Financing Agreement relating to the financing of each
New Aircraft together with a true and complete set of the closing
documentation (including legal opinions) delivered to the related Loan
Trustee, Subordination Agent and Pass Through Trustee under the related
Participation Agreement.

                  (e) If after giving any Closing Notice, there shall be a
delay in the delivery of a New Aircraft, or if on the Scheduled Closing
Date of a New Aircraft the financing thereof in the manner contemplated
hereby shall not be consummated for whatever reason, the Company shall give
the parties hereto and the Policy Provider prompt notice thereof.
Concurrently with the giving of such notice of postponement or
subsequently, the Company shall give the parties hereto and the Policy
Provider a substitute Closing Notice specifying the date (the "Substitute
Closing Date") to which the applicable financing shall have been
re-scheduled (which shall be a Business Day before the earlier of (x) the
120th day following the delivery of the Aircraft from the Seller to the
Company or Group, as the case may be (or, with Rating Agency Confirmation,
a longer period following delivery of such New Aircraft from Seller to the
Company or Group) and (y) the Cut-Off Date on which the Escrow Agent shall
be entitled to withdraw one or more Deposits under the Deposit Agreement to
enable each Pass Through Trustee to fund its purchase of the related
Equipment Notes). Upon receipt of any such notice of postponement, the Pass
Through Trustee shall comply with its obligations under Section 5.01(b) of
the Trust Supplement and thereafter the financing of the relevant New
Aircraft shall take place on the Substitute Closing Date therefor (all on
and subject to the terms and conditions of the relevant Financing
Agreements) unless further postponed as provided herein.

                  (f) Anything in this Section 2 to the contrary
notwithstanding, the Company shall have the right at any time on or before
the Scheduled Closing Date of any New Aircraft, and subsequent to its
giving a Closing Notice therefor, to postpone the Scheduled Closing Date of
such New Aircraft so as to enable the Company to change its election to
treat such New Aircraft as a Leased Aircraft or an Owned Aircraft by
written notice of such postponement to the other parties hereto. The
Company shall subsequently give the parties hereto and the Policy Provider
a substitute Closing Notice complying with the provisions of Section 2(b)
hereof and specifying the new Closing Date for such postponed New Aircraft
(which shall be a Business Day occurring before the earlier of (x) the
120th day following the delivery of the Aircraft from the Seller to the
Company or Group, as the case may be (or, with Rating Agency Confirmation,
a longer period following delivery of such New Aircraft from Seller to the
Company or Group) and (y) the Cut-Off Date and on which the Escrow Agent
shall be entitled to withdraw Deposits under the Deposit Agreement
sufficient to enable the Pass Through Trustee to fund its purchase of the
related Equipment Notes). All other terms and conditions of this Note
Purchase Agreement shall apply to the financing of any such New Aircraft on
the re-scheduled Closing Date therefor except the re-scheduled Closing Date
shall be deemed the Closing Date of such New Aircraft for all purposes of
this Section 2.

                  (g) If the delivery date for any New Aircraft under the
Aircraft Purchase Agreement is delayed for more than 30 days beyond the
month scheduled for delivery or February 7, 2001, the Company may identify
for delivery a substitute aircraft therefor meeting the following
conditions (together with the substitute aircraft referred to in the next
sentence, a "Substitute Aircraft"): (i) a Substitute Aircraft must be an
Airbus Model A330 aircraft delivered by the Seller to the Company after
January 31, 2000 and (ii) the Company shall be obligated to obtain prior
written consent of the Policy Provider and to obtain Rating Agency
Confirmation in respect of the replacement of any New Aircraft by
Substitute Aircraft. Upon the satisfaction of the conditions set
forth above with respect to a Substitute Aircraft, the New Aircraft to be
replaced shall cease to be subject to this Agreement and all rights and
obligations of the parties hereto concerning such New Aircraft shall cease,
and such Substitute Aircraft shall become and thereafter be subject to the
terms and conditions of this Agreement to the same extent as such New
Aircraft.

                  (h) The Company shall have no liability for the failure
of the Pass Through Trustee to purchase Equipment Notes with respect to any
New Aircraft or Substitute Aircraft, other than the Company's obligation,
if any, to pay the Deposit Make-Whole Amount pursuant to Section 5(a)(i) of
this Agreement.

                  (i) The parties agree that if, in connection with the
delivery of a New Aircraft or Substitute Aircraft, any Owner Participant
who is to be a party to any Lease Financing Agreements shall not be a
"citizen of the United States" within the meaning of Section 40102(a)(15)
of the Act, then the applicable Lease Financing Agreements shall be
modified, consistent with the Mandatory Document Terms (as such Mandatory
Document Terms may be modified in accordance with Schedule V hereto), to
require such Owner Participant to enter into a voting trust, voting powers
or similar arrangement satisfactory to the Company that (A) enables such
New Aircraft or Substitute Aircraft to be registered in the United States
and (B) complies with the FAA regulations issued under the Act applicable
thereto.

                  (j) Anything herein to the contrary notwithstanding, the
Company shall not have the right, and shall not be entitled, at any time to
request the issuance of Series G Equipment Notes to the Pass Through
Trustee in an aggregate principal amount in excess of the amount of the
Deposits then available for withdrawal by the Escrow Agent under and in
accordance with the provisions of the Deposit Agreement.

                  (k) Anything herein to the contrary notwithstanding, the
Company and Group shall each have the right to accept delivery of a New
Aircraft under the Aircraft Purchase Agreement on the delivery date
therefor under the Aircraft Purchase Agreement; provided that the Company
shall in any event, give the parties hereto a Closing Notice specifying a
Scheduled Closing Date not later than one hundred twenty (120) days after
the delivery of such New Aircraft under the Aircraft Purchase Agreement
(or, with Rating Agency Confirmation, a longer period following delivery of
such New Aircraft from Seller to the Company or Group) and before the
Cut-Off Date and otherwise complying with the provisions of Section 2(b)
hereof. All other terms and conditions of this Note Purchase Agreement
shall apply to the financing of any such New Aircraft on the new Scheduled
Closing Date therefor except (i) the Scheduled Closing Date shall be deemed
to be the Closing Date of such New Aircraft for all purposes of this
Section 2 and (ii) the related Financing Agreements shall be amended to
reflect the original delivery of such New Aircraft to the Company.

            Section 3. Conditions Precedent. The obligation of the Pass
Through Trustee to enter into, and to cause the Subordination Agent to
enter into, any Participation Agreement as directed pursuant to a Closing
Notice and to perform its obligations thereunder is subject to satisfaction
of the following conditions:

                  (a)  no Triggering Event shall have occurred; and

                  (b) the Company shall have delivered a certificate to the
Pass Through Trustee, the Policy Provider and the Liquidity Provider
stating that (i) such Participation Agreement and the other Financing
Agreements to be entered into pursuant to such Participation Agreement do
not vary the Mandatory Economic Terms and contain the Mandatory Document
Terms (as such Mandatory Document Terms may be modified in accordance with
Schedule V hereto) and (ii) any substantive modification of such Financing
Agreements from the forms of such Financing Agreements attached to this
Agreement do not materially and adversely affect the Policy Provider or the
Certificate Holders, and such certification shall be true and correct.

                  (c) a copy of the Rating Agency Confirmation required
under Section 2 shall have been delivered to the Pass Through Trustee.

            Anything herein to the contrary notwithstanding, the obligation
of the Pass Through Trustee to purchase Equipment Notes shall terminate on
the Cut-Off Date.

                           (vii)  If the Depositary's short-term rating shall
      at any time fall below the Depositary Threshold Rating from either
      Moody's or Standard & Poor's, the Company shall, within 60 days of
      such event occurring, cause the Depositary to be replaced with a
      depository bank (a "Replacement Depositary") on the following terms
      and preconditions:

                               (1)  the Replacement Depositary must
      be one that either (x) meets the Depositary Threshold Rating or (y)
      with respect to which the Company shall have obtained written
      confirmation from each Rating Agency that such Replacement Depositary
      will not cause a reduction of any rating then in effect for the Class
      G Certificates by such Rating Agency (without regard to any
      downgrading of any rating of the Depositary being replaced and
      without regard to the Policy) and, in either case, the Company shall
      have obtained written confirmation from each Rating Agency that such
      replacement will not cause a reduction or withdrawal of any rating
      then in effect for the Class G Certificates by such Rating Agency
      (without regard to any downgrades of any rating of the Depositary
      being replaced and without regard to the Policy);

                               (2)  the Company shall pay all fees,
      expenses and other amounts then owing to the replaced Depositary; and

                               (3)  the Company shall cause the
      Escrow Agent and the Replacement Depositary to enter into a
      Replacement Deposit Agreement for the Class G Certificates and shall
      cause the Replacement Depositary to deliver to the Company, the
      Policy Provider and each Rating Agency legal opinions and other
      closing documentation substantially similar in scope and substance as
      those that were delivered by the Depositary being replaced in
      connection with the execution and delivery of the Deposit Agreement
      being replaced.

      Upon satisfaction of the foregoing conditions, the Company shall
      instruct the Pass Through Trustee, and the Pass Through Trustee
      agrees, to execute and deliver to the Escrow Agent a duly completed
      Withdrawal Certificate (as defined in the Escrow and Paying Agent
      Agreement) together with a Notice of Replacement Withdrawal (as
      defined in the Escrow and Paying Agent Agreement).

      Each of the parties hereto agrees, at the Company's request, to enter
      into any amendments to this Agreement, the Escrow and Paying Agent
      Agreement and any other Operative Documents as may be necessary or
      desirable to give effect to the replacement of the Depositary with
      the Replacement Depositary and the replacement of the Deposit
      Agreement with the Replacement Deposit Agreements.

      Upon the execution and delivery of the Replacement Deposit Agreement,
      the Replacement Depositary shall be deemed to be the Depositary with
      all of the rights and obligations of the Depositary hereunder and
      under the other Operative Documents and the Replacement Deposit
      Agreement shall be deemed to be the Deposit Agreement hereunder and
      under the other Operative Documents, except that the obligations of
      the replaced Depositary under the last sentence of Section 2.2 of the
      Deposit Agreement shall remain in full force and effect
      notwithstanding the execution and delivery of the Replacement Deposit
      Agreement.

                  (b) State Street Bank and Trust Company of Connecticut,
National Association, in its individual capacity, covenants with each of
the other parties to this Agreement that it will, immediately upon
obtaining knowledge of any facts that would cast doubt upon its continuing
status as a "citizen of the United States" as defined in 49 U.S.C. ss.
40102(a)(15) and promptly upon public disclosure of negotiations in respect
of any transaction which would or might adversely affect such status,
notify in writing all parties hereto of all relevant matters in connection
therewith. Upon State Street Bank and Trust Company of Connecticut,
National Association giving any such notice, State Street Bank and Trust
Company of Connecticut, National Association shall, subject to Section 8.02
of any Indenture then entered into, resign as Loan Trustee in respect of
such Indenture.

                  (c) The Company further covenants that it will not issue
or cause to be issued any "Class C Pass Through Trust Certificates" (as
contemplated by the Company's Prospectus Supplement dated February 25,
1999) unless the Company has received written confirmation from each of the
Rating Agencies that the issuance of such certificates and the related
series C equipment notes will not result in a withdrawal, suspension or
downgrading of the rating of the Class G Certificates (without regard to
the Policy). The Company agrees, in connection with the issuance of such
"Class C Pass Through Trust Certificates," to cause the pass through
trustee for the Class C pass through trust that is formed to enter into an
amended and restated Note Purchase Agreement or a separate note purchase
agreement and in either case, to provide for the purchase of series C
equipment notes by the pass through trustee for such class C pass through
trust.

            Section 6. Notices. Unless otherwise specifically provided
herein, all notices required or permitted by the terms of this Agreement
shall be in English and in writing, and any such notice shall become
effective upon being delivered personally or, if promptly confirmed by
mail, when dispatched by facsimile or other written telecommunication,
addressed to such party hereto at its address or facsimile number set forth
below the signature of such party at the foot of this Agreement. Notice to
the Policy Provider shall be given at the address specified in the Policy
Provider Agreement.

            Section 7. Expenses and Indemnity. (a) The Company agrees to
pay to the Subordination Agent when due an amount or amounts equal to the
fees payable to the Liquidity Provider under Section 2.03 of the Liquidity
Facility and the related Fee Letter (as defined in the Intercreditor
Agreement) multiplied by a fraction the numerator of which shall be the
then outstanding aggregate amount of the Deposits under the Deposit
Agreement and the denominator of which shall be the sum of (x) the then
outstanding aggregate principal amount of the Series G Equipment Notes
issued under all of the Indentures and (y) the then outstanding aggregate
amount of the Deposits under the Deposit Agreement.

                  (b) The Company agrees to pay to the Subordination Agent
when due for application in accordance with the Intercreditor Agreement an
amount or amounts equal to the fees payable to the Policy Provider under
the Policy Fee Letter (as defined in the Policy Provider Agreement)
multiplied by a fraction the numerator of which shall be the then
outstanding aggregate amount of the Deposits under the Deposit Agreement
and the denominator of which shall be the sum of (x) the then outstanding
aggregate principal amount of the Series G Equipment Notes issued under all
of the Indentures and (y) the then outstanding aggregate amount of the
Deposits under the Deposit Agreement.

                  (c) So long as no Equipment Notes have been issued in
respect of any Aircraft, the Company agrees to pay (i) to the Subordination
Agent when due (A) the amount equal to interest on any Downgrade Advance
(other than any Applied Downgrade Advance) payable under Section 3.07 of
the Liquidity Facility minus Investment Earnings while such Downgrade
Advance shall be outstanding, (B) the amount equal to interest on any
Non-Extension Advance (other than any Applied Non- Extension Advance)
payable under Section 3.07 of the Liquidity Facility minus Investment
Earnings while such Non-Extension Advance shall be outstanding and (C) any
other amounts owed to the Liquidity Provider by the Subordination Agent as
borrower under the Liquidity Facility (other than amounts due as repayment
of advances thereunder or as interest on such advances, except to the
extent payable pursuant to clause (A) or (B)), (ii) all compensation and
reimbursement of expenses, disbursements and advances payable by the
Company under the Pass Through Trust Agreement, (iii) all compensation and
reimbursement of expenses and disbursements payable to the Subordination
Agent under the Intercreditor Agreement except with respect to any income
or franchise taxes incurred by the Subordination Agent in connection with
the transactions contemplated by the Intercreditor Agreement, the Liquidity
Facility or the Policy Provider Agreement and (iv) all compensation and
reimbursement of expenses and disbursements payable to the Policy Provider
under Section 3.7(i) of the Intercreditor Agreement, and (v) in the event
the Company requests any amendment to this Note Purchase Agreement or any
Operative Document, all reasonable fees and expenses (including, without
limitation, fees and disbursements of counsel) of the Escrow Agent, the
Paying Agent and/or the Policy Provider in connection therewith. For
purposes of this Section 7(c), the terms "Applied Downgrade Advance,"
"Applied Non-Extension Advance," "Downgrade Advance", "Investment Earnings"
and "Non- Extension Advance" shall have the meanings specified in the
Liquidity Facility.

                  (d) The Company hereby agrees to indemnify each of the
Escrow Agent and the Paying Agent from and against, and agrees to protect,
save and keep harmless the Policy Provider from any and all losses, claims
and expenses imposed on, incurred by or asserted against the Policy
Provider in any way relating to, based on or arising from the execution,
delivery and performance of this Agreement, the Deposit Agreement or the
Escrow and Paying Agent Agreement; provided, that the foregoing indemnity
shall not extend to any of the Escrow Agent or the Paying Agent with
respect to any loss, claim or expense to the extent such loss, claim or
expense is attributable to (i) a breach by any such party of this
Agreement, the Deposit Agreement or the Escrow and Paying Agent Agreement
or (ii) such party's gross negligence or willful misconduct.

                  (e) The Company hereby agrees to indemnify the Policy
Provider from and against, and agrees to protect, save and keep harmless
each of them from any and all losses, claims and expenses imposed on,
incurred by or asserted against any of them in any way relating to, based
on or arising from the enforcement by the Policy Provider of its rights as
a subrogee under the Escrow and Paying Agent Agreement; provided, that the
foregoing indemnity shall not extend to the Policy Provider with respect to
any loss, claim or expense to the extent such loss, claim or expense is
attributable to the Policy Provider's gross negligence or willful
misconduct and provided further, that the Policy Provider shall have no
claim against any "Indenture Estate" or "Trust Indenture Estate" (as such
terms are defined in the Financing Agreements) for any payments under this
Section 7(e).

            Section 8. Further Assurances. Each party hereto shall duly
execute, acknowledge and deliver, or shall cause to be executed,
acknowledged and delivered, all such further agreements, instruments,
certificates or documents, and shall do and cause to be done such further

Provider, the Policy Provider or the Loan Trustee the provisions of

extent such section requires special counsel for the Lessee to deliver an
opinion relating to Section 1110 of the Bankruptcy Code), 4(a)(xii),

deliver to the Loan Participant or the Loan Trustee, as the case may be,
the legal opinions to be provided to such Persons thereunder (recognizing
that the lawyers rendering such opinions may be changed),
Sections 7(c), 7(h), the second sentence of Section 7(n), 7(q), 7(z), 14(f)
or 14(h) of the Participation Agreement Form or of the provisions of

        its beneficial interest in the Trust Estate will be used directly
        or indirectly by Lessee to purchase or carry any "margin security"
        as such term is defined in Regulation U of the Board of Governors
        of the Federal Reserve System;

               (xiii) on the Delivery Date, all sales or use tax then due
        and for which Lessee is responsible pursuant to Section 6(b)(i)
        hereof shall have been paid, other than such taxes which are being
        contested by Lessee in good faith and by appropriate proceedings so
        long as such proceedings do not involve any material risk of the
        sale, forfeiture or loss of the Aircraft;

               (xiv) except as may have been disclosed in the Lessee's
        reports filed with the Securities and Exchange Commission, there
        are no pending or threatened actions or proceedings that
        individually or in the aggregate which could be expected to have a
        material adverse effect on the condition (financial or otherwise),
        business or properties of Lessee and its subsidiaries considered as
        one enterprise;

               (xv) the Owner Trustee will receive good and marketable
        title to the Aircraft from Lessee free and clear of all Liens,
        except the rights of Lessee under the Lease and the Lease
        Supplement covering the Aircraft, the Lien of the Trust Indenture,
        the beneficial interest of the Owner Participant in the Aircraft,
        and the Liens permitted by clause (iv) (solely for Taxes not yet
        due but excluding any such Taxes being contested) and clause (v) of
        Section 6 of the Lease (solely securing obligations that are not
        yet due, but excluding any such obligations being contested);

               (xvi) the audited consolidated balance sheet of Lessee with
        respect to fiscal year ended _____2 included in Lessee's annual
        report on Form 10-K for the year ended _____, [as amended], filed
        by Lessee with the SEC, and the related consolidated statements of
        income, stockholders' equity and cash flows for the period then
        ended, have been prepared in conformity with GAAP and present
        fairly in all material respects the financial condition of Lessee
        and its consolidated subsidiaries as of such date and the result
        of its operations and cash flows for such period; and

- --------
        2    Insert most recent fiscal year end.


               (xvii) Lessee holds all licenses, permits and franchises
        from the appropriate Government Entities necessary to authorize
        Lessee to lawfully engage in air transportation and to carry on
        scheduled commercial passenger service as currently conducted,
        except where the failure to so hold any such license, permit or
        franchise would not be reasonably likely to have a material adverse
        effect on the condition (financial or otherwise), business or
        properties of Lessee and its subsidiaries considered as one
        enterprise.

               (b)  General Tax Indemnity.
                    ---------------------

               (i) Indemnity. Except as provided in Section 6(b)(ii)

               (ii)   Exclusions from General Tax Indemnity.  The provisions of
        Section 6(b)(i) shall not apply to:

                      (1) Taxes on, based on, measured by or with respect
               to the gross or net income, gross or net receipts, minimum
               or alternative taxes, tax preferences, capital, net worth,

               use, license, rental, ad valorem, value added tax (to the
               extent that such value added tax is not imposed as a
               substitute for an income tax) or property taxes) (a) imposed
               by the United States or by any state or local government or
               taxing authority or (b) imposed by any foreign government or
               taxing authority except where such Tax is imposed by reason
               of the use, location, registration, subleasing, leasing or
               operation of the Aircraft or the presence or activities of
               Lessee in such jurisdiction and exceeds the Tax that would
               have been imposed on the Indemnitee regardless of the use,
               location, registration, subleasing, leasing or operation of
               the Aircraft or the presence or activities of Lessee;

                      (2)    Taxes that would not have been imposed but for a
               Lessor's Lien;

                      (3) Taxes resulting from a voluntary transfer by the
               Owner Participant of the Aircraft, the Trust Estate, or the
               Operative Documents, or any interest therein, or a transfer
               relating to bankruptcy or similar proceedings involving the
               Owner Participant;

               negligence of the Indemnitees;

                      (5) Taxes imposed with respect to any period after
               the expiration of the Lease or the earlier discharge in full
               of Lessee's obligation to pay Termination Value;

                      (6) Taxes imposed on any transferee (a) if such Tax
               would not have been imposed on the original Indemnitee, or
               (b) to the extent such Tax exceeds the amount of Tax that
               would have been imposed on the original Indemnitee;

                      (7)    Taxes which have been included in the Lessor's
               Cost;

                      (8) Taxes imposed by a government or taxing authority
               of any jurisdiction that would have been imposed on the
               Indemnitee for activities or property in such jurisdiction
               unrelated to the transactions contemplated by the Operative
               Documents;

                      (9)    Taxes being contested pursuant to the contest
               provisions contained in Section 6(b)(iv);

                      (10) Taxes imposed on the Owner Trustee or the Owner
               Participant based on, measured by or imposed with respect to
               any fees, commissions or compensation received by it;

                      (11)   Taxes imposed on the Owner Participant and
               indemnified under the Tax Indemnity Agreement;

                      (12) Interest, penalties and additions to Tax to the
               extent imposed as a result of the failure of the Owner
               Participant to timely and properly file any return, unless
               such failure is caused by Lessee's failure to timely provide
               information required to be provided under the Operative
               Documents;

                      (13) Taxes that would not have been imposed but for
               an Indemnitee's breach of any covenant or the inaccuracy of
               any representation or warranty of such Indemnitee in any of
               the Operative Documents;

                      (14) Taxes in the nature of an intangible or similar
               Tax imposed upon, or with respect to, (a) the value of the
               Owner Participant's interest in the Trust or the Indenture
               Trust or (b) the value or the principal amount of any
               Lender's interest in any of the Equipment Notes;

                      (15)   U.S. withholding taxes imposed on payments to a
               foreign person; and

                      (16)   Taxes imposed by section 4975 of the Code or any
               successor provision thereto.


        References to the Owner Participant shall include such Person's
respective successors and permitted assigns, officers, directors, servants,
employees, agents and Affiliates.

               (iii) Payments. The Lessee's indemnity obligation to an
        Indemnitee under this Section 6(b) shall include any amount
        necessary to hold such Indemnitee harmless (as determined in good
        faith by such Indemnitee), after taking into account any tax
        benefits actually realized by such Indemnitee (including, without
        limitation, any benefits realized as a result of an indemnifiable
        Tax being utilized by such Indemnitee as a credit against Taxes not
        indemnifiable under this Section 6(b)), from the net amount of all
        Taxes actually required to be paid by such Indemnitee by reason of
        the receipt or accrual of the amounts payable under this Section
        6(b). Each Indemnitee shall provide Lessee with such
        certifications, information and documentation as shall be
        reasonably requested by Lessee to minimize any indemnity payment
        pursuant to this Section 6(b).

        At Lessee's request, the computation of the amount of any indemnity
payment owed by Lessee or any amount owed by an Indemnitee to Lessee
pursuant to this Section 6(b) shall be verified and certified by a
nationally recognized independent public accounting firm selected by the
Indemnitee and reasonably acceptable to Lessee. The costs of such
verification (including the fee of such public accounting firm) shall be
borne by Lessee unless such verification shall result in an adjustment in
Lessee's favor of 5% or more of the net present value of the payment as
computed by such Indemnitee, in which case the costs shall be paid by such
Indemnitee.

        Each Indemnitee shall promptly forward to Lessee any written
notice, bill or advice received by it from any government or taxing
authority concerning any Tax for which it seeks indemnification under this
Section 6(b); provided, however, the failure to provide such notice shall
not adversely affect such Indemnitee's right to indemnity under this
Section 6(b) except to the extent such failure materially adversely affects
the contest of the Tax. The Lessee shall pay any amount for which it is
liable pursuant to this Section 6(b) directly to the appropriate government
or taxing authority if legally permissible or, upon demand of an
Indemnitee, to such Indemnitee within 30 days of such demand (or, if a
contest occurs in accordance with Section (6)(b)(iv), within 30 days after
a Final Determination (as defined below)), but in no event more than one
business day prior to the date the Tax to which such amount payable
hereunder relates is due, provided, Lessee shall not be required to make
any payment pursuant to this Section 6(b)(iii) unless the Indemnitee elects
to pay such Tax claimed and sue for a refund as provided in Section
6(b)(iv). If requested by an Indemnitee in writing, Lessee shall furnish to
the appropriate Indemnitee the original or a certified copy of a receipt
for Lessee's payment of any Tax or such other evidence of payment of Tax.
For purposes of this Section 6(b), a "Final Determination" shall mean (A) a
decision, judgment, decree or other order by any court of competent
jurisdiction that occurs pursuant to the provisions of Section 6(b)(iv),
which decision, judgment, decree or other order has become final and
unappealable, (B) a closing agreement or settlement agreement entered into
in accordance with Section 6(b)(iv) that has become binding and is not
subject to further review or appeal absent fraud or misrepresentation or
(C) the termination of administrative proceedings and the expiration of the
time for instituting a claim in a court proceeding.

        If any Indemnitee shall actually realize a tax savings by reason of
any Tax paid or indemnified by Lessee pursuant to this Section 6(b) and
such savings was not otherwise taken into account in computing such payment
or indemnity, such Indemnitee shall pay to Lessee an amount equal to the
lesser of (A) the amount of such tax savings, plus any additional tax
savings actually realized as the result of any payment made pursuant to
this sentence and (B) the amount of all payments made by Lessee to such
Indemnitee (reduced by any payments previously made by such Indemnitee to
Lessee pursuant to this Section 6(b)), and the excess, if any, of the
amount described in clause (A) over the amount described in clause (B)
shall be carried forward and applied to reduce pro tanto any subsequent
obligations of Lessee to make payments to such Indemnitee pursuant to this
Section 6(b)). No Indemnitee shall have any obligation to make any payment
while a Lease Event of Default has occurred and is continuing.

        Any Taxes that are imposed on any Indemnitee as a result of the
disallowance or reduction of any tax benefit referred to in this Section
6(b) pursuant to a Final Determination by a tax authority as to which such
Indemnitee has made the payment to Lessee required hereby or which tax
benefit was otherwise taken into account in computing Lessee's indemnity
obligation pursuant to this Section 6(b) in a taxable year subsequent to
the utilization by such Indemnitee shall be treated as a Tax for which
Lessee is obligated to indemnify pursuant to this Section 6(b).


               (iv) Contests. If a written claim is made against an
        Indemnitee or if any proceeding is commenced against an Indemnitee
        (including a written notice of such proceeding) for Taxes as to
        which Lessee could be liable for payment or indemnity hereunder, or
        if an Indemnitee makes a determination that a Tax is due for which
        Lessee could have an indemnity obligation hereunder, such
        Indemnitee shall promptly give Lessee notice in writing of such
        claim (provided, however, that the failure to provide such notice
        shall not affect Lessee's obligations hereunder to the Owner
        Participant unless such failure shall materially adversely affect
        the right to contest such claim) and shall not take any action with
        respect to such claim or Tax without the consent of Lessee for 30
        days following the receipt of such notice by Lessee; provided,
        however, that, if such Indemnitee shall be required by law to take
        action prior to the end of such 30-day period, such Indemnitee
        shall, in such notice to Lessee, so inform Lessee, and such
        Indemnitee shall take no action for as long as it is legally able
        to do so (it being understood that an Indemnitee shall be entitled
        to pay the Tax claimed and sue for a refund prior to the end of
        such 30-day period if (A)(I) the failure to so pay the Tax would
        result in substantial penalties (unless immediately reimbursed by
        Lessee) and the act of paying the Tax would not prejudice the right
        to contest or (II) the failure to so pay would result in criminal
        penalties and (B) such Indemnitee shall act in connection with
        paying the Tax in the manner that is the least prejudicial to the
        pursuit of the contest). In addition, such Indemnitee shall
        (provided that Lessee shall have agreed to keep such information
        confidential other than to the extent necessary in order to contest
        the claim) furnish Lessee with copies of any requests for
        information from any taxing authority relating to such Taxes with
        respect to which Lessee may be required to indemnify hereunder. If
        requested by Lessee in writing within 30 days after its receipt of
        such notice, such Indemnitee shall, at the expense of Lessee
        (including all reasonable out-of-pocket costs and reasonable
        attorney and accountants fees), in good faith contest (or, if
        permitted by applicable law, allow Lessee to contest) through
        appropriate administrative and judicial proceedings the validity,
        applicability or amount of such Taxes by (X) resisting payment
        thereof, (Y) not paying the same except under protest if protest is
        necessary and proper or (Z) if the payment is made, using
        reasonable efforts to obtain a refund thereof in an appropriate
        administrative and/or judicial proceeding. If requested to do so by
        Lessee, the Indemnitee shall appeal any adverse administrative or
        judicial decision, except that the Indemnitee shall not be required
        to pursue any appeals to the United States Supreme Court. If and to
        the extent the Indemnitee is able to separate the contested issue
        or issues from other issues arising in the same administrative or
        judicial proceeding that are unrelated to the transactions
        contemplated by the Operative Documents without, in the good faith
        judgment of such Indemnitee, adversely affecting such Indemnitee,
        such Indemnitee shall permit Lessee to control the conduct of any
        such proceeding and shall provide to Lessee such information or
        data that is in such Indemnitee's control or possession that is
        reasonably necessary to conduct such contest. In the case of a
        contest controlled by an Indemnitee, such Indemnitee shall consult
        with Lessee in good faith regarding the manner of contesting such
        claim and shall keep Lessee reasonably informed regarding the
        progress of such contest. An Indemnitee shall not fail to take any
        action expressly required by this Section 6(b)(iv) (including,
        without limitation, any action regarding any appeal of an adverse
        determination with respect to any claim) or settle or compromise
        any claim without the prior written consent of Lessee (except as
        contemplated by this Section 6(b)(iv)).

        Notwithstanding the foregoing, in no event shall an Indemnitee be
required to pursue any contest (or to permit Lessee to pursue any contest)
unless (A) Lessee shall have agreed to pay such Indemnitee on demand all
reasonable out-of-pocket costs and reasonable attorney and accountants fees
that such Indemnitee shall incur in connection with contesting such claim,
(B) if such contest shall involve the payment of the claim, Lessee shall
advance the amount thereof plus (to the extent indemnified hereunder)
interest, penalties and additions to tax with respect thereto that are
required to be paid prior to the commencement of such contest on an
interest-free basis and with no additional net after-tax cost to such
Indemnitee (and such Indemnitee shall promptly pay to Lessee any net
realized tax benefits resulting from any imputed interest deduction arising
from such interest free advance from Lessee plus any tax benefits resulting
from making any such payment), (C) such Indemnitee shall have reasonably
determined that the action to be taken will not result in any material risk
of forfeiture, sale or loss of the Aircraft (unless Lessee shall have made
provisions to protect the interests of any such Indemnitee), (D) no Lease
Event of Default shall have occurred and be continuing at the
time the contest is begun unless Lessee has provided security for its
obligations hereunder by advancing to such Indemnitee before proceeding
with such contest, the amount of the Tax being contested, plus any interest
and penalties and an amount estimated in good faith by such Indemnitee for
reasonable expenses, and (E) in the case of a contest that is being pursued
by an Indemnitee, the aggregate amount of the claim (together with the
amount of all similar or logically related claims that have been or could
be raised with any or all of the other Aircraft leased by the Owner
Participant to Lessee or raised in any other audit for which Lessee would
have an indemnity obligation under this Section 6(b)(iv)) is at least
$3,000. Notwithstanding the foregoing, if any Indemnitee shall release,
waive, compromise or settle any claim which may be indemnifiable by Lessee
pursuant to this Section 6(b) without the written permission of Lessee,
Lessee's obligation to indemnify such Indemnitee with respect to such claim
(and all directly related claims and claims based on the outcome of such
claim) shall terminate, subject to this Section 6(b)(iv), and subject to
Section 6(b)(iii), such Indemnitee shall repay to Lessee any amount
previously paid or advanced to such Indemnitee with respect to such claim,
plus interest at the rate that would have been payable by the relevant
taxing authority with respect to a refund of such Tax.

        Notwithstanding anything contained in this Section 6(b), an
Indemnitee will not be required to contest the imposition of any Tax and
shall be permitted to settle or compromise any claim without Lessee's
consent if such Indemnitee (A) shall waive its right to indemnity under
this Section 6(b), with respect to such Tax (and any directly related claim
and any claim the outcome of which is determined based upon the outcome of
such claim) and (B) shall pay to Lessee any amount previously paid or
advanced by Lessee pursuant to this Section 6(b) with respect to such Tax,
plus interest at the rate that would have been payable by the relevant
taxing authority with respect to a refund of such Tax.


               (v) Refunds. If any Indemnitee shall receive a refund or
        credit (or would have received such refund or credit but for a
        counterclaim or other claim not indemnified by Lessee hereunder (a
        "deemed refund or credit")) with respect to all or any part of any
        Taxes paid, reimbursed or advanced by Lessee, in each case, whether
        by means of a deduction, credit, refund or otherwise, and which was
        not taken into account in computing such payment or indemnity, such
        Indemnitee shall pay to Lessee within 30 days of such receipt or,
        in the case of a deemed refund or credit, within 30 days of the
        resolution of such contest, an amount equal to the lesser of (A)
        the amount of such refund or credit or deemed refund or credit
        actually realized by such Indemnitee, plus any additional tax
        savings actually realized by such Indemnitee as a result of any
        payment made pursuant to this sentence (including clause (A)), and
        (B) such tax payment, reimbursement or advance by Lessee to such
        Indemnitee theretofore made pursuant to this Section 6(b) and the
        excess, if any, of the amount described in clause (A) over the
        amount described in clause (B) shall be carried forward and
        applied to reduce pro tanto any subsequent obligations of Lessee
        to make payments to such Indemnitee pursuant to this Section
        6(b)). If, in addition to such refund or credit (or deemed refund
        or credit), such Indemnitee shall receive or be credited with (or
        would have received but for a counterclaim or other claim not
        indemnified by Lessee hereunder) an amount representing interest
        on the amount of such refund or credit or deemed refund or
        credit, as the case may be, such Indemnitee shall pay to Lessee
        within 30 days of such receipt or, in the case of a deemed refund
        or credit, within 30 days of the resolution or such contest, that
        portion of such interest that shall be fairly attributable to
        Taxes paid, reimbursed or advanced by Lessee prior to the receipt
        of such refund or credit or deemed refund or credit. Each
        Indemnitee agrees to reasonably cooperate with Lessee in claiming
        and pursuing any such refunds or credits of any Taxes payable or
        indemnifiable pursuant to this Section 6(b).

               (vi) Tax Filing. If any report, return or statement is
        required to be filed with respect to any Tax which is subject to
        indemnification under this Section 6(b), Lessee shall timely file
        the same (except for any such report, return or statement which an
        Indemnitee has timely notified Lessee in writing that such
        Indemnitee intends to file, or for which such Indemnitee is
        required by law to file, in its own name); provided, that the
        relevant Indemnitee shall furnish Lessee with any information in
        such Indemnitee's possession or control that is reasonably
        necessary to file any such return, report or statement and is
        reasonably requested in writing by Lessee, but in no event shall be
        obligated to furnish tax returns, although it may be required to
        furnish relevant information contained therein. The Lessee shall
        either file such report, return or statement and send a copy of
        such report, return or statement to such Indemnitee, and the Owner
        Trustee if the Indemnitee is not the Owner Trustee, or, where
        Lessee is not permitted to file such report, return or statement,
        it shall notify such Indemnitee of such requirement and prepare and
        deliver such report, return or statement to such Indemnitee in a
        manner satisfactory to such Indemnitee within a reasonable time
        prior to the time such report, return or statement is to be filed.

               (vii) Forms. Each Indemnitee agrees to furnish from time to
        time to Lessee or the Indenture Trustee or to such other Person as
        Lessee or the Indenture Trustee may designate, at Lessee's or the
        Indenture Trustee's request, such duly executed and properly
        completed forms as may be necessary or appropriate in order to
        claim any reduction of or exemption from any withholding or other
        Tax imposed by any government or taxing authority, if (A) such
        reduction or exemption is available to such Indemnitee and (B)
        Lessee has provided such Indemnitee with any information
        necessary to complete such form not otherwise reasonably
        available to such Indemnitee.

               (viii) Non-Parties. If an Indemnitee is not a party to this
        Agreement, Lessee may require the Indemnitee to agree in writing,
        in a form reasonably acceptable to Lessee, to the terms of this
        Section 6(b) prior to making any payment to such Indemnitee under
        this Section 6(b).

               (ix) Subrogation. Upon payment of any Tax by Lessee pursuant
        to this Section 6(b) to or on behalf of an Indemnitee, Lessee,
        without any further action, shall be subrogated to any claims that
        such Indemnitee may have relating thereto. Such Indemnitee shall
        cooperate with Lessee to permit Lessee to pursue such claims.

               (c) General Indemnity. Lessee hereby agrees to indemnify
each Indemnitee against, and agrees to protect, save and keep harmless each
of them from (whether or not the transactions contemplated herein or in any
of the other Operative Documents are consummated), any and all Expenses
imposed on, incurred by or asserted against any Indemnitee, in any way
relating to, based on or arising out of (A) the execution, delivery and
performance of the Operative Documents or the Pass Through Documents and
the transactions contemplated thereby; (B) the manufacture, purchase,
acceptance or rejection of the Airframe or any Engine or Parts; (C) the
Aircraft (or any portion thereof) or any engine installed on the Airframe
or any airframe on which an Engine is installed whether or not arising out
of the manufacture, purchase, registration, reregistration, financing,
refinancing, ownership, delivery, nondelivery, inspection, lease, sublease,
possession, storage, use or non-use, operation, maintenance, overhaul,
modification, alteration, condition, replacement, repair, substitution,

limitation, any violation of law relating to the Aircraft (including
environmental laws), latent or other defects, whether or not discoverable,
strict tort liability and any claim for patent, trademark or copyright
infringement; (D) the offer or sale of any interest in the Trust Estate or
the Trust Agreement or any similar interest on or prior to the Delivery
Date (including any violation of securities laws or ERISA); or (E) the
offer or sale of any interest in the Equipment Notes or the Pass Through
Certificates (or other evidence of the debt relating to the Aircraft) on
the Delivery Date or in connection with a refinancing in accordance with
the terms hereof (including any violation of securities laws or ERISA);
provided, that the foregoing indemnity shall not extend to an Indemnitee
with respect to any Expense to the extent such Expense is attributable to
one or more of the following: (1) any representation or warranty by such
Indemnitee in the Operative Documents or the Pass Through Documents being
incorrect, or (2) the failure by such Indemnitee to perform or observe any
of its agreements, covenants or conditions in any of the Operative
Documents or the Pass Through Documents, or (3) the willful misconduct or
the gross negligence of such Indemnitee, or (4) (A) in the case of any
Indemnitee, the offer, sale or other disposition (voluntary or involuntary)
by such Indemnitee of all or any part of its interest in the Airframe or
any Engine (other than during the continuance of a Lease Event of Default
or pursuant to and in accordance with Sections 9, 10, 15 or 19 of the
Lease), (B) in the case of a Note Holder, the offer, sale or other
disposition (voluntary or involuntary) by such Note Holder of all or any

Indemnitee, the offer, sale or other disposition by such Indemnitee of all
or any part of such Indemnitee's interest in the Operative Documents, or
(5) any Tax (other than taxes under ERISA or Section 4975 of the Code that
are not excluded from the foregoing indemnity by reason of clause 18 below)
whether or not Lessee is required to indemnify for such Tax pursuant to
Section 6(b) hereof (it being understood that Section 6(b) hereof and the
Tax Indemnity Agreement exclusively provide for Lessee's liability with
respect to Taxes), or (6) in the case of the Owner Participant, the offer
or sale by the Owner Participant after the Delivery Date of any interest in
the Trust Estate or the Trust Agreement or any similar interest except
during the continuance of an Event of Default so long as such disposition
is made in accordance with Section 7(k), or (7) in the case of the Owner
Trustee in its individual and trust capacities, and the Affiliates,
successors and assigns thereof, a failure on the part of the Owner Trustee
to distribute in accordance with the Trust Agreement any amounts
distributable by it thereunder, or (8) in the case of the Indenture Trustee
in its individual and trust capacities, failure on the part of the
Indenture Trustee to distribute in accordance with the Trust Indenture any
amounts distributable by it thereunder, or (9) in the case of any Pass
Through Trustee, failure on the part of such Pass Through Trustee or the
Subordination Agent to distribute in accordance with the Intercreditor
Agreement and the Pass Through Trust Agreement amounts received and
distributable thereunder, or (10) the authorization or giving or
withholding of any future amendments, supplements, waivers or consents with
respect to any of the Operative Documents which amendments, supplements,
waivers or consents (a) are not or were not requested by Lessee or (b) are
not occasioned by a specific requirement of the Operative Documents, or
(11) except to the extent fairly attributable to acts or events occurring
during the Term or actions taken (or required to be taken and not taken)
during the Term, actions taken (or required to be taken and not taken) or
events occurring after the earlier of: (I) the return of possession of the
Aircraft to the Owner Trustee or its designee pursuant to the terms of the
Lease (other than pursuant to and in accordance with Section 15 thereof, in
which case Lessee's liability under this Section 6(c) shall survive for so
long as Lessor shall be entitled to exercise remedies under such Section
15), (II) the termination of the Term in accordance with Section 9 of the
Lease, (III) the payment by Lessee of all amounts required to be paid under
the Lease following an Event of Loss or (IV) termination of the Lease and
payment by Lessee of all amounts required to be paid by Lessee pursuant to
the terms of the Operative Documents or (12) any amount which any
Indemnitee expressly agrees to pay under any Operative Document or any
amount which is expressly stated to be an Expense that is not reimbursable
by Lessee under the Operative Documents, or (13) any amount that is an
ordinary and usual operating or overhead expense of any Indemnitee (it
being understood out-of-pocket expenses payable to third parties do not
constitute "ordinary and usual operating and overhead expenses"), or (14)
any amounts relating to the deregistration with the FAA of the Aircraft as
a result of the Owner Participant or the Owner Trustee, as the case may be,
not being a Citizen of the United States or any other act or omission of
the Owner Trustee, the Owner Participant or such Indemnitee, or (15) any
amounts attributable to any Lien which such Indemnitee is required to
remove pursuant to the terms of the Operative Documents or the Pass Through
Documents, or (16) any loss of tax benefits or increases in tax liability
whether or not the Lessee is required to indemnify an Indemnitee elsewhere
in the Operative Documents, or (17) principal of, or interest or premium on
the Equipment Notes, or (18) any prohibited transaction, within the meaning
of Section 406 of ERISA or Section 4975(c)(1) of the Code, occurring with
respect to the purchase or holding of any Pass Through Certificate (i) over
which purchase or holding the Owner Participant or any Affiliate thereof
has discretion or control (other than in the capacity of a directed trustee
or custodian), or (ii) by an employee benefit plan, within the meaning of
Section 3(3) of ERISA, or individual retirement account or plan subject to
Section 4975 of the Code with respect to which the Owner Participant (or
any Affiliate thereof) has the power, directly or indirectly, to appoint or
terminate, or to negotiate the terms of the management agreement with, the
Person or Persons having discretion or control (other than in the capacity
of a directed trustee or custodian), over such purchase or holding, or (19)
without limiting any indemnification otherwise expressly provided under the
Operative Documents, any amount payable under the Pass Through Documents
(other than the Participation Agreement) to the extent not included in the
definition of Supplemental Rent.

               Lessee's indemnity obligation to an Indemnitee under this
Section 6(c) shall equal the amount which, after taking into account any
Tax imposed upon the receipt or accrual of the amounts payable under this
Section 6(c) and any tax benefits realized by such Indemnitee as a result
of the accrual or payment of such Expense shall equal the amount of the
Expense indemnifiable under this Section 6(c).

               If any Indemnitee shall realize a tax savings by reason of
any Tax paid or indemnified by Lessee pursuant to this Section 6(c)
(whether such tax savings shall be by means of a foreign tax credit,
depreciation or cost recovery deduction or otherwise) and such savings is
not otherwise taken into account in computing such payment or indemnity
such Indemnitee shall pay to Lessee an amount equal to the lesser of (i)
the amount of such tax savings, plus any additional tax savings recognized
as the result of any payment made pursuant to this sentence, when, as if,
and to the extent, realized or (ii) the amount of all payments pursuant to
this Section 6(c) by Lessee to such Indemnitee (less any payments
previously made by such Indemnitee to Lessee pursuant to this Section 6(c))
(and the excess, if any, of the amount described in clause (i) over the
amount described in clause (ii) shall be carried forward and applied to
reduce pro tanto any subsequent obligations of Lessee to make payments to
such Indemnitee pursuant to this Section 6(c)).

               Nothing in this Section 6(c) shall be construed as a
guaranty by Lessee of payments due pursuant to the Equipment Notes or of
the residual value of the Aircraft.

               If a claim is made against an Indemnitee involving one or
more Expenses and such Indemnitee has notice thereof, such Indemnitee shall
promptly after receiving such notice give notice of such claim to Lessee;
provided that the failure to give such notice shall not affect the
obligations of Lessee hereunder except to the extent Lessee is prejudiced
by such failure or the Lessee's indemnification obligations are increased
as a result of such failure. If no Lease Event of Default shall have
occurred and be continuing, Lessee shall be entitled, at its sole cost and
expense, acting through counsel reasonably acceptable to the respective
Indemnitee, (A) in any judicial or administrative proceeding that involves
solely a claim for one or more Expenses, to assume responsibility for and
control thereof, (B) in any judicial or administrative proceeding involving
a claim for one or more Expenses and other claims related or unrelated to
the transactions contemplated by the Operative Documents, to assume
responsibility for and control of such claim for Expenses to the extent
that the same may be and is severed from such other claims (and such
Indemnitee shall use its best efforts to obtain such severance), and (C) in
any other case, to be consulted by such Indemnitee with respect to judicial
proceedings subject to the control of such Indemnitee and to be allowed, at
Lessee's sole expense, to participate therein. Notwithstanding any of the
foregoing to the contrary, Lessee shall not be entitled to assume
responsibility for and control of any such judicial or administrative
proceedings if such proceedings will involve a material risk of the sale,
forfeiture or loss of, or the creation of any Lien (other than a Permitted
Lien) on, the Aircraft, the Trust Estate, the Trust Indenture Estate or any
part thereof unless in such an event Lessee shall have posted a bond or
other security satisfactory to the relevant Indemnitees in respect to such
risk. The Indemnitee may participate at its own expense and with its own
counsel in any judicial proceeding controlled by Lessee pursuant to the
preceding provisions.

               The affected Indemnitee shall supply Lessee with such
information reasonably requested by Lessee as is necessary or advisable for
Lessee to control or participate in any proceeding to the extent permitted
by this Section 6(c). Such Indemnitee shall not enter into a settlement or
other compromise with respect to any Expense without the prior written
consent of Lessee, which consent shall not be unreasonably withheld or
delayed, unless such Indemnitee waives its right to be indemnified with
respect to such Expense under this Section 6(c).

               The Lessee shall supply the Indemnitee with such information
reasonably requested by the Indemnitee as is necessary or advisable for the
Indemnitee to control or participate in any proceeding to the extent
permitted by this Section 6(c).

               Upon payment of any Expense pursuant to this Section 6(c),
Lessee, without any further action, shall be subrogated to any claims the
Indemnitee may have relating thereto. The Indemnitee agrees to give such
further assurances or agreements and to cooperate with Lessee to permit
Lessee to pursue such claims, if any, to the extent reasonably requested by
Lessee.

               If an Indemnitee is reimbursed, in whole or in part, with
respect to any Expense paid by Lessee hereunder, it will promptly pay the
amount refunded, including interest received thereto (but not an amount in
excess of the amount Lessee or any of its insurers has paid in respect of
such Expense pursuant to this Section 6(c)) over to Lessee.

               To the extent permitted by applicable law, interest at the
Base Rate plus one percent (1.0%) shall be paid, on demand, on any amount
or indemnity not paid when due pursuant to this Section 6 until the same
shall be paid. Such interest shall be paid in the same manner as the unpaid
amount in respect of which such interest is due.

               Any amount which is payable to Lessee by any Person pursuant
to this Section 6 shall not be paid to Lessee if a Lease Event of Default
has occurred and is continuing or if any payment is due and owing by Lessee
to such Person under the Lease or any other Operative Document. Any such
amount shall be held by such Person (the Lessee hereby granting a security
interest in such amount to such Person) and, if a Lease Event of Default
shall have occurred and be continuing, shall be applied against Lessee's
obligations hereunder to such Person as and when due (and, to the extent
that Lessee has no obligations hereunder to such Person, such amount shall
be paid to Lessee). At such time as there shall not be continuing any such
Lease Event of Default or there shall not be due and owing any such
payment, such amount shall be paid to Lessee to the extent not previously
applied in accordance with the immediately preceding sentence.


        SECTION 7.    REPRESENTATIONS, WARRANTIES AND COVENANTS.

               (a)  Covenants Regarding Citizenship.  Each of the Owner
Participant and First Security Bank, National Association, in its
individual capacity, represents and warrants to the other parties to this
Agreement that it is, and on the Delivery Date will be, a Citizen of the
United States without making use of any voting trust, voting powers
agreement or similar arrangement. The Owner Participant agrees, solely for
the benefit of Lessee and the Loan Participants, that if (i) it shall cease
to be, or believes itself likely to cease to be, a Citizen of the United
States and (ii) the Aircraft shall or would therefore become ineligible for
registration in the name of the Owner Trustee under the Transportation Code
and regulations then applicable thereunder, then the Owner Participant
shall (at its own expense and without any reimbursement or indemnification
from Lessee) as soon as practicable, but in any event within 60 days of
obtaining knowledge of such ineligibility or loss of citizenship effect a
voting trust, voting powers agreement or other similar arrangement or take
any other action as may be necessary to prevent any deregistration and to
maintain the United States registration of the Aircraft. It is agreed that:
(A) the Owner Participant shall be liable to pay on request to each of the
other parties hereto and to each holder of a Equipment Note for any damages
suffered by any such other party or holder as the result of the
representation and warranty of the Owner Participant in the first sentence
of this Section 7(a) proving to be untrue as of the Delivery Date; and (B)
the Owner Participant shall be liable to Lessee, any Sublessee and the Loan
Participants for any damages which may be incurred by Lessee, any Sublessee
or the Loan Participants as a result of the Owner Participant's failure to
comply with its obligations pursuant to the second sentence of this Section
7(a). Each party hereto agrees, upon the request and at the sole expense of
the Owner Participant, to cooperate with the Owner Participant in complying
with its obligations under the provisions of the second sentence of this
Section 7(a). First Security Bank, National Association, in its individual
capacity, agrees that if at any time an officer or responsible employee of
the Corporate Trust Department of First Security Bank, National
Association, shall obtain actual knowledge that First Security Bank,
National Association, has ceased to be a Citizen of the United States
without making use of a voting trust, voting powers agreement or similar
arrangement, it will promptly resign as Owner Trustee (if and so long as
such citizenship is necessary under the Transportation Code as in effect at
such time or, if it is not necessary, if and so long as the Owner Trustee's
citizenship would have any material adverse effect on the Loan
Participants, Lessee or the Owner Participant), effective upon the
appointment of a successor Owner Trustee in accordance with Section 9.01 of
the Trust Agreement. If the Owner Participant or First Security Bank,
National Association, in its individual capacity, does not comply with the
requirements of this Section 7(a), the Owner Trustee, the Indenture Trustee
and the Participants hereby agree that a Lease Default or Lease Event of
Default shall not have occurred and be continuing due to non-compliance by
Lessee with the registration requirements in the Lease.

               (b)  Location of Records.  First Security Bank, National
Association, in its individual capacity, agrees that it will not change the
location of its principal place of business or the office where it
maintains its books and records with respect to the Aircraft and the Trust
Estate to a location outside of Salt Lake City, Utah, without prior written
notice to all parties.

               (c) Securities Act. Each Loan Participant represents and
warrants that neither it nor anyone acting in its behalf has offered any
Equipment Notes for sale to, or solicited any offer to buy any Equipment
Note from, any Person or entity other than in a manner in compliance with,
and which does not require registration under, the Securities Act or the
rules and regulations thereunder.

               (d) Reregistration. The Owner Participant, the Indenture
Trustee, the Pass Through Trustee and each Loan Participant agree that, at
any time after the Depreciation Period, so long as no Lease Event of
Default shall have occurred and be continuing, Lessee may elect to effect a
change in registration of the Aircraft, at Lessee's cost and expense, so
long as the country of registry of the Aircraft is a country listed on
Exhibit A. Upon the request of the Lessee, Exhibit A shall be amended from
time to time to include any other country which the Owner Participant and
the Indenture Trustee have determined, acting reasonably, would provide
substantially equivalent protection for the rights of owner participants,
lessors or lenders in similar transactions as provided under the laws of
the United States and the states thereof. In order for Lessee to effect a
change in the country of registry of the Aircraft, Lessee shall deliver to
the Owner Participant, the Owner Trustee (in its individual capacity) and
the Indenture Trustee the following:

     (I)  an Officer's Certificate certifying that (A) the insurance or
          self-insurance required by Section 11 of the Lease shall be in
          full force and effect at the time of such change in registration
          after giving effect to such change in registration, (B) all
          indemnities in favor of the Owner Participant, the Owner Trustee
          (in its individual capacity and as trustee under the Trust
          Agreement) and the Indenture Trustee under any Operative Document
          afford each such party substantially the same protection as
          provided prior to such change of registry, (C) the lien of the
          Trust Indenture in favor of the Trustee will continue as a first
          priority lien following such change of registry, (D) such change
          will not result in the imposition of, or increase in the amount
          of, any Tax for which Lessee is not required to indemnify, or is
          not then willing to enter into a binding agreement to indemnify,
          the Owner Participant, the Note Holders, the Indenture Trustee,
          the Owner Trustee (in its individual capacity and as trustee
          under the Trust Agreement), the Indenture Trustee or the Trust
          Estate pursuant to this Agreement or the Tax Indemnity Agreement,
          and (E) that the new country of registry imposes aircraft
          maintenance standards not materially less stringent from those of
          any Permitted Foreign Air Authority; and

     (II) a favorable opinion (subject to customary exceptions) of counsel
          (opinion and counsel reasonably acceptable to the Owner
          Participant) addressed to the Owner Participant and the Indenture
          Trustee, from counsel of recognized reputation qualified in the
          laws of the relevant jurisdiction to the effect that: (A) the
          obligations of Lessee, and the rights and remedies of the Owner
          Trustee, under the Lease shall remain valid, binding and (subject
          to customary bankruptcy and equitable remedies exceptions and to
          other exceptions customary in foreign opinions generally)
          enforceable under the laws of such jurisdiction (or the laws of
          the jurisdiction to which the laws of such jurisdiction would
          refer as the applicable governing law); (B) it is not necessary,
          solely as a consequence of such change in registration and
          without giving effect to any other activity of the Owner Trustee,
          the Owner Participant or the Indenture Trustee (or any Affiliate
          thereof), as the case may be, for the Owner Trustee, the Owner
          Participant or the Indenture Trustee to register or qualify to do
          business in such jurisdiction; (C) there is no tort liability of
          the owner of an aircraft not in possession thereof under the laws
          of such jurisdiction (it being agreed that, in the event such
          latter opinion cannot be given in a form satisfactory to the
          Owner Participant, such opinion shall be waived if insurance
          reasonably satisfactory to the Owner Participant is provided to
          cover such risk); (D) unless Lessee shall have agreed to provide
          insurance covering the risk of requisition of use of such
          Aircraft by the government of such jurisdiction so long as such
          Aircraft is registered under the laws of such jurisdiction, the
          laws of such jurisdiction require fair compensation by the
          government of such jurisdiction payable in currency freely
          convertible into Dollars for the loss of use of such Aircraft in
          the event of the requisition by such government of such use; and
          (E) after giving effect to such change in registration, the Lien
          of the Trust Indenture on the Owner Trustee's right, title and
          interest in and to the Aircraft and the Lease shall continue as a
          valid and duly perfected first priority security interest and all
          filing, recording or other action necessary to protect the same
          shall have been accomplished (or, if such opinion cannot be given
          at the time of such proposed change in registration because such
          change in registration is not yet effective, (1) the opinion
          shall detail what filing, recording or other action is necessary,
          and (2) the Owner Trustee and the Indenture Trustee shall have
          received a certificate from Lessee that all possible preparations
          to accomplish such filing, recording and other action shall have
          been done, and such filing, recording and other action shall be
          accomplished and a supplemental opinion to that effect shall be
          delivered to the Owner Trustee and the Indenture Trustee on or
          prior to the effective date of such change in registration).

Upon receipt of the foregoing certificate and opinion, the Owner
Participant and the Indenture Trustee will instruct the Owner Trustee to
make such change of registration.

               Lessee shall pay all reasonable costs, expenses, fees,
recording and registration taxes, including the reasonable fees and
expenses of counsel to the Owner Trustee, the Owner Participant and the
Indenture Trustee, and other charges in connection with any such change in
registration.

               (e) Owner Participant Representations and Warranties. The
Owner Participant represents and warrants to Lessee, the Owner Trustee, the
Indenture Trustee, the Pass Through Trustee, the Subordination Agent, the
Liquidity Provider, the Policy Provider and the Owner Trustee, in its
capacity as such and in its individual capacity, as follows:

               (i) it is duly incorporated, validly existing and in good
        standing under the laws of the State of __________ and has the

        operations and to own or lease its properties, and has the
        corporate power and authority to enter into and to perform its
        obligations under the Owner Participant Documents; this Agreement
        and the other Owner Participant Documents have been duly
        authorized, executed and delivered by it; and this Agreement and
        each of the other Owner Participant Documents constitute the legal,
        valid and binding obligations of the Owner Participant enforceable
        against it in accordance with its respective terms, except as such
        enforceability may be limited by bankruptcy, insolvency,
        reorganization, moratorium or other similar laws affecting the
        rights of creditors generally and by general principles of equity,
        whether considered in a proceeding at law or in equity; and the
        Owner Participant is a Qualified Owner Participant;

               (ii) neither (A) the execution and delivery by the Owner
        Participant of the Owner Participant Documents nor (B) compliance
        by it with all of the provisions thereof, (x) will contravene any
        law or order of any court or governmental authority or agency
        applicable to or binding on the Owner Participant (it being
        understood that no representation or warranty is made with respect
        to laws, rules or regulations relating to aviation or to the nature
        of the equipment owned by the Owner Trustee other than such laws,
        rules or regulations relating to the citizenship requirements of
        the Owner Participant under applicable law), or (y) will
        contravene the provisions of, or constitutes or has constituted
        or will constitute a default under, or result in the creation of
        any Lien (other than Liens provided for in the Operative
        Documents) upon any property of the Owner Participant under, its
        certificate of incorporation or by-laws or any indenture,
        mortgage, contract or other agreement or instrument to which the
        Owner Participant is a party or by which it or any of its
        property may be bound or affected;

               (iii) no authorization or approval or other action by, and
        no notice to or filing with, any governmental authority or
        regulatory body (other than as required by the Transportation Code
        or the regulations promulgated thereunder) is required for the due
        execution, delivery or performance by it of the Owner Participant
        Documents;

               (iv) there are no pending or, to its knowledge, threatened
        actions or proceedings before any court or administrative agency or
        arbitrator which would materially adversely affect the Owner
        Participant's ability to perform its obligations under this
        Agreement, the Participation Agreement, the Tax Indemnity Agreement

        Note or Pass Through Certificate or any interest in or to the Trust
        Estate, the Trust Agreement or any similar interest for sale to, or
        solicited any offer to acquire any of the same from, anyone other
        than the Pass Through Trustee and the Owner Participant; and the
        Owner Trustee has not authorized anyone to act on its behalf (it
        being understood that in arranging and proposing the refinancing
        contemplated hereby and agreed to herein by the Owner Trustee, the
        Lessee has not acted as agent of the Owner Trustee) to offer
        directly or indirectly any Equipment Note, any Certificate or any
        interest in and to the Trust Estate, the Trust Agreement or any
        similar interest for sale to, or to solicit any offer to acquire
        any of the same from, any Person;

               (xii) it is a Citizen of the United States (without making
        use of a voting trust agreement, voting powers agreement or similar
        arrangements);

               (xiii) there has not occurred any event which constitutes
        (or, to the best of its knowledge would, with the passing of time
        or the giving of notice or both, constitute) an Indenture Event of
        Default which has been caused by or relates to the Owner Trustee,
        in its individual capacity, and which is presently continuing; and

               (xiv) on the Delivery Date the Owner Trustee shall have
        received whatever title to the Aircraft as was conveyed to it by
        Lessee.

               (t) Owner Participant Obligations on Lease Termination. The
Owner Participant covenants and agrees that if (i) Lessee has elected
pursuant to Section 9(a)(1) of the Lease to terminate the Lease by causing
the Aircraft to be sold pursuant to Section 9(b) of the Lease and (ii) the
Owner Trustee has, pursuant to Section 9(b) of the Lease, given to Lessee
written notice of Lessor's election to retain title to the Aircraft and
(iii) the Owner Trustee has failed to make, on or before the Termination
Date, any payment required to be made by the Owner Trustee pursuant to
Section 9(b) of the Lease in connection with its retention of title to the
Aircraft, the Owner Participant will indemnify Lessee for any losses,
damages, costs or expenses of any kind (including any additional rents paid
by Lessee and any fees and expenses of lawyers, appraisers, brokers or
accountants) incurred as a consequence of such failure by the Owner
Trustee.

               (u) Transfer of Title; Assumption of Equipment Notes. Each
of the Owner Participant, the Owner Trustee, the Indenture Trustee and
Lessee covenants and agrees that if Lessee elects (A) to purchase the
Aircraft pursuant to Section 19(b) or Section 20 of the Lease or (B) to
terminate the Lease and purchase the Aircraft pursuant to Section 19(c) of
the Lease, then each of the parties will execute and deliver appropriate
documentation transferring all right, title and interest in the Aircraft to
Lessee (including, without limitation, such bills of sale and other
instruments and documents as Lessee shall reasonably request to evidence
(on the public record or otherwise) such transfer and the vesting of all
right, title and interest in and to the Aircraft in Lessee), and if Lessee,
in connection with such purchase, elects to assume the obligations of the
Owner Trustee pursuant to the Trust Indenture and the Equipment Notes each
of the parties will execute and deliver appropriate documentation
permitting Lessee to assume such obligations on the basis of full recourse
to Lessee, maintaining the security interest in the Aircraft created by the
Trust Indenture, releasing the Owner Participant and the Owner Trustee from
all future obligations in respect of the Equipment Notes, the Trust
Indenture and all other Operative Documents and all such other actions as
are reasonably necessary to permit such assumption by Lessee.
Notwithstanding the provisions of this Section 7(u), unless waived by the
Loan Participants, Lessee shall not be entitled to assume the Equipment
Notes on the date for purchase of the Aircraft pursuant to Section 19(c) or
20 of the Lease if on such date a Specified Default or Lease Event of
Default shall have occurred and be continuing.

               Notwithstanding the foregoing, Lessee shall not be entitled
to assume the obligations of the Owner Trustee in respect of the Equipment
Notes unless Lessee causes to be delivered to the Indenture Trustee an
opinion of counsel to the effect that (i) the Lien of the Trust Indenture
continues to be a valid and duly perfected first priority security interest
in and to the Aircraft, (ii) the Indenture Trustee will be entitled to the
benefits of 11 U.S.C. Section 1110; provided that the opinion required by
subclause (ii) need only be given if immediately prior to such assumption
the Owner Trustee would have been entitled to the benefits of 11 U.S.C.
Section 1110 and (iii) the Pass Through Trusts will not be subject to
Federal income taxation and the Note Holders will not recognize income,
gain or loss for Federal income tax purposes as a result of such assumption
and will be subject to taxation in the same amounts, in the same manner,
and at the same times as would have been the case if such assumption had
not occurred.

               (v)   Lessee Merger Covenant.  Lessee will not consolidate
with or merge into any other corporation or convey, transfer or lease
substantially all of its assets as an entirety to any Person unless:

               (i) the corporation formed by such consolidation or into
        which Lessee is merged or the Person which acquires by conveyance,
        transfer or lease substantially all of the assets of Lessee as an
        entirety shall be (i) organized and validly existing under the laws
        of the United States of America or any state thereof or the
        District of Columbia, (ii) a Citizen of the United States and (iii)
        a Certificated Air Carrier, if and so long as such status is a
        condition of entitlement to the benefits of Section 1110 of the
        Bankruptcy Code with respect to the Lease or the Aircraft;

               (ii) the corporation formed by such consolidation or into
        which Lessee is merged or the Person which acquires by conveyance,
        transfer or lease substantially all of the assets of Lessee as an
        entirety shall execute and deliver to the Owner Trustee, the
        Indenture Trustee and the Owner Participant an agreement in form
        and substance reasonably satisfactory to the Owner Participant a
        duly authorized, valid, binding and enforceable agreement
        containing an assumption by such successor corporation or Person of
        the due and punctual performance and observance of each covenant
        and condition of the Operative Documents to which Lessee is a party
        to be performed or observed by Lessee;

               (iii) immediately after giving effect to such transaction,
        no Lease Event of Default shall have occurred and be continuing;
        and

               (iv) Lessee shall have delivered to the Owner Trustee, the
        Indenture Trustee and the Owner Participant a certificate signed by
        the President, any Executive Vice President, any Senior Vice
        President or any Vice President and by the Secretary or an
        Assistant Secretary of Lessee, and an opinion of counsel (which may
        be Lessee's General Counsel, Deputy General Counsel, Associate
        General Counsel or Assistant General Counsel) reasonably
        satisfactory to the Owner Participant, each to the effect that such
        consolidation, merger, conveyance, transfer or lease and the
        assumption agreement mentioned in clause (ii) above comply with
        this Section 7(v) and that all conditions precedent herein provided
        for relating to such transaction have been complied with.

               Upon any such consolidation or merger or any such
conveyance, transfer or lease of substantially all of the assets of Lessee
as an entirety in accordance with this Section 7(v), the successor
corporation or Person formed by such consolidation or into
which Lessee 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, Lessee under this Agreement with the same effect as if such
successor corporation or Person had been named as Lessee herein. No such
conveyance, transfer or lease of substantially all of the assets of Lessee
as an entirety shall have the effect of releasing Lessee or any successor
corporation or Person which shall theretofore have become such in the
manner prescribed in this Section 7(v) from its liability in respect of any
Operative Document to which it is a party.

               (w) Further Assurances. Lessee, at its expense, will take,
or cause to be taken, such action with respect to the recording, filing,
re-recording and refiling of the Lease, the Lease Supplement, the Trust
Agreement, the Trust Indenture, the Trust Supplement and any financing
statements or other instruments as are necessary to maintain, so long as
the Trust Indenture or the Lease is in effect, the perfection of the
security interests created by the Trust Indenture and any security interest
that may be claimed to have been created by the Lease and the ownership
interest of the Owner Trustee in the Aircraft or will furnish to the Owner
Trustee, the Owner Participant and the Indenture Trustee timely notice of
the necessity of such action, together with such instruments, in execution
form, and such other information as may be required to enable them to take
such action. Lessee will notify the Owner Trustee, the Owner Participant
and the Indenture Trustee of any change in the location of its chief
executive office (as such term is used in Article 9 of the Uniform
Commercial Code) promptly after making such change or in any event within
the period of time necessary under applicable law to prevent the lapse of
perfection (absent refiling) of financing statements filed under the
Operative Documents.

               (x) Rent Adjustments. Section 3 of the Lease contemplates
that, under certain circumstances, the Owner Participant will make certain
recalculations of Basic Rent, EBO Amount and Termination Value, and the
Owner Participant hereby agrees to make such recalculations as and when
contemplated by the Lease and subject to all the terms and conditions of
the Lease and promptly to take such further actions as may be necessary or
desirable to give effect to and to cause the Owner Trustee to give effect
to the provisions of Section 3 of the Lease.

               (y) Owner Participant Costs on Return. The Owner Participant
hereby agrees with Lessee that it will pay, or cause to be paid, all costs
and expenses that are for the account of the Owner Trustee pursuant to
Section 5 of the Lease without the right of reimbursement or
indemnification from Lessee.

               (z)  Transfer of Equipment Notes.  Each Loan Participant hereby
represents, warrants and agrees that it shall not transfer any interest in
any Equipment Note unless and until the transferee agrees in writing
(copies of which shall be provided by the Indenture Trustee to Lessee, the
Owner Trustee and the Owner Participant) to make the representations
contemplated to be made by a Loan Participant in this Agreement and to be
bound by the terms of this Agreement and the Trust Indenture (including,
without limitation, the representations and covenants set forth in Sections
7(c), 7(h), 7(n) and 7(q) hereof and this Section 7(z) and Sections 2.03,
2.14 and 4.03 of the Trust Indenture).

               (aa) Representations and Warranties of Pass Through Trustee.
The Pass Through Trustee represents and warrants to Lessee, the Indenture
Trustee, the Subordination Agent, the Liquidity Provider, the Policy
Provider, the Owner Participant and the Owner Trustee, in its capacity as

               (i) the Pass Through Trustee is a national banking
        association duly organized, validly existing and in good standing
        under the laws of the United States and has the full corporate

        Connecticut and the United States pertaining to its banking, trust
        and fiduciary powers to execute and deliver each of the Pass
        Through Trust Agreements, the Intercreditor Agreement and this

        Trust Agreements, the Intercreditor Agreement and this Agreement;

               (ii) this Agreement, each of the Pass Through Trust
        Agreements and the Intercreditor Agreement have been duly
        authorized, executed and delivered by the Pass Through Trustee;
        this Agreement, each of the Pass Through Trust Agreements and the
        Intercreditor Agreement constitute the legal, valid and binding
        obligations of the Pass Through Trustee enforceable against it in
        accordance with their respective terms, except as the same may be
        limited by applicable bankruptcy, insolvency, reorganization,
        moratorium or similar laws affecting the rights of creditors
        generally and by general principles of equity, whether considered
        in a proceeding at law or in equity;

               (iii) none of the execution, delivery and performance by the
        Pass Through Trustee of any of the Pass Through Trust Agreements,
        the Intercreditor Agreement or this Agreement, the purchase by the
        Pass Through Trustee of the Equipment Notes pursuant to this
        Agreement, or the issuance of the Certificates pursuant to the Pass
        Through Trust Agreements, contravenes any law, rule or regulation
        of the State of Connecticut or any United States governmental
        authority or agency regulating the Pass Through Trustee's banking,
        trust or fiduciary powers or any judgment or order applicable to or
        binding on the Pass Through Trustee and does not contravene or
        result in any breach of, or constitute a default under, the Pass
        Through Trustee's articles of association or by-laws or any
        agreement or instrument to which the Pass Through Trustee is a
        party or by which it or any of its properties may be bound;

               (iv) neither the execution and delivery by the Pass Through
        Trustee of any of the Pass Through Trust Agreements, the
        Intercreditor Agreement or this Agreement, nor the consummation by
        the Pass Through Trustee of any of the transactions contemplated
        hereby or thereby, requires the consent or approval of, the giving
        of notice to, the registration with, or the taking of any other
        action with respect to, any Connecticut governmental authority or
        agency or any Federal governmental authority or agency regulating
        the Pass Through Trustee's banking, trust or fiduciary powers;

               (v) there are no Taxes payable by the Pass Through Trustee

        and performance by the Pass Through Trustee of this Agreement, any
        of the Pass Through Trust Agreements or the Intercreditor Agreement
        (other than franchise or other taxes based on or measured by any
        fees or compensation received by the Pass Through Trustee for
        services rendered in connection with the transactions contemplated
        by any of the Pass Through Trust Agreements), and there are no

        received by the Pass Through Trustee for services rendered in
        connection with the transactions contemplated by any of the Pass
        Through Trust Agreements), and, assuming that the trusts created by
        the Pass Through Trust Agreements will not be taxable as
        corporations, but rather, each will be characterized either as a
        grantor trust under subpart E, Part I, of Subchapter J of the Code
        or as a partnership, such trusts will not be subject to any Taxes
        imposed by the State of Connecticut or any political subdivision
        thereof;

               (vi) there are no pending or threatened actions or
        proceedings against the Pass Through Trustee before any court or
        administrative agency which individually or in the aggregate, if
        determined adversely to it, would materially adversely affect the
        ability of the Pass Through Trustee to perform its obligations
        under this Agreement, the Intercreditor Agreement or any Pass
        Through Trust Agreement;

               (vii) except for the issue and sale of the Pass Through
        Trust Certificates contemplated hereby, the Pass Through Trustee
        has not directly or indirectly offered any Equipment Note for sale
        to any Person or solicited any offer to acquire any Equipment Notes
        from any Person, nor has the Pass Through Trustee authorized anyone
        to act on its behalf to offer directly or indirectly any Equipment
        Note for sale to any Person, or to solicit any offer to acquire any
        Equipment Note from any Person; and the Pass Through Trustee is not
        in default under any Pass Through Trust Agreement; and

               (viii) the Pass Through Trustee is not directly or
        indirectly controlling, controlled by or under common control with
        the Owner Participant, the Owner Trustee or Lessee.

               (bb) Representations and Warranties of Subordination Agent.
The Subordination Agent represents and warrants to Lessee, the Indenture
Trustee, the Pass Through Trustee, the Liquidity Provider, the Policy
Provider, the Owner Participant and the Owner Trustee, in its capacity as
such and in its individual capacity, as follows:

               (i) the Subordination Agent is a national banking
        association duly organized, validly existing and in good standing

        the rights of creditors generally and by general principles of
        equity, whether considered in a proceeding at law or in equity;

               (iii) none of the execution, delivery and performance by the

        instrument to which the Subordination Agent is a party or by
        which it or any of its properties may be bound;

               (iv) neither the execution and delivery by the Subordination

        the Liquidity Facilities);

               (vi) there are no pending or threatened actions or
        proceedings against the Subordination Agent before any court or
        administrative agency which individually or in the aggregate, if

        ability of the Subordination Agent to perform its obligations under
        this Agreement, the Intercreditor Agreement, the Policy Provider
        Agreement or any Liquidity Facility;

               (vii) the Subordination Agent has not directly or indirectly

               (ix) [Certain Other Covenants of the Owner Participant and
        the Indenture Trustee. The Owner Participant hereby unconditionally
        agrees with Lessee, and only with Lessee (and not with any other
        party to this Participation Agreement), that on behalf of the Owner
        Trustee it will make available to the Indenture Trustee funds
        sufficient to pay the Indenture Trustee the amounts (the "Deferred
        Equity Amounts") set forth on the dates (the "Deferred Equity
        Dates") set forth in Schedule IV attached hereto; provided, that
        the Owner Participant shall not be obligated to make such funds
        available if an event specified in Section 14(e), (f) or (g) of the
        Lease which either does, or with the giving of notice or passage of
        time, or both, would constitute an Event of Default or Lease Event
        of Default shall have occurred and be continuing on the date on
        which such funds are to be made available. The Owner Participant
        and the Owner Trustee hereby direct the Indenture Trustee, and the
        Indenture Trustee hereby agrees, to apply any such payment of
        Deferred Equity Amounts to the payment of principal and interest on
        the Equipment Notes, as appropriate, which may be due and payable
        pursuant to the provisions of the Trust Indenture on such Deferred
        Equity Date. The Owner Participant agrees to make any such payment
        of Deferred Equity Amounts in immediately available funds on or
        before 11:00 a.m. New York City time, on the Deferred Equity Date.
        The Owner Participant agrees to give Lessee notice by 11:00 a.m.,
        New York City time, on the Deferred Equity Date if it has failed to
        make the payment of the Deferred Equity Amount due on such date.
        The Indenture Trustee agrees to give Lessee notice by 12:00 noon,
        New York City time, on the Deferred Equity Date if it has failed to
        receive the payment of the Deferred Equity Amount due on such date.
        In the event the Owner Participant fails to make such payment,
        Lessee shall make the Advance under Section 3(g) of the Lease and
        the Owner Participant shall cause Lessor to comply with all of its
        obligations under said Section 3(g). The Owner Participant agrees
        to repay the amount of any Advance made pursuant to Section 3(g) of
        the Lease forthwith following the making thereof together with
        interest at a rate per annum equal to the Base Rate plus 2%
        commencing on the date of such Advances to the date of repayment
        and agrees that its obligation shall be a full recourse
        obligation of the Owner Participant. All amounts paid to the
        Lessee by the Owner Participant in respect of an Advance or
        deducted by the Lessee pursuant to Section 3(g) of the Lease
        shall be applied first to payment to Lessee of interest and then
        to payment to Lessee of amounts equal to the Advance.]3

        SECTION 8. RELIANCE OF LIQUIDITY PROVIDER AND POLICY PROVIDER. Each
of the parties hereto agrees and acknowledges that the Liquidity Provider
and the Policy Provider shall each be third party beneficiaries of each of
the representations, warranties and covenants made herein by such party,
and that each of the Liquidity Provider and the Policy Provider may rely on
such representations and warranties to the same extent as if such
representations and warranties were made to each of the Liquidity Provider
and the Policy Provider directly. Lessee agrees and acknowledges that each
of the Liquidity Provider and the Policy Provider shall be third party
beneficiaries of the indemnities contained in Section 6(c) hereof, and each
of the Liquidity Provider and Policy Provider may rely on such indemnities
to the same extent as if such indemnities were made to each of the
Liquidity Provider and Policy Provider directly.

        SECTION 9. OTHER DOCUMENTS. Each of the Owner Participant and the
Owner Trustee hereby (a) agrees with Lessee and the Loan Participants to
comply with all of the terms of the Trust Agreement (as the same may
hereafter be amended or supplemented from time to time in accordance with
the terms thereof) applicable to it; (b) agrees with Lessee and the
Indenture Trustee not to amend, supplement or otherwise modify any
provision of the Trust Agreement in a manner adversely affecting such party
without the prior written consent of such party; and (c) agrees with Lessee
and the Loan Participants not to revoke the Trust Agreement without the
prior written consent of Lessee and the Indenture Trustee. Notwithstanding
the foregoing, so long as the Lease has not been terminated, the
Subordination Agent, the Pass Through Trustee, the Indenture Trustee, the
Owner Participant and the Owner Trustee hereby agree for the benefit of
Lessee that without the consent of Lessee they will not amend, modify or
supplement the definition of "Secured Obligations" or Articles II, III, IX
or Section 5.02 of the Trust Indenture. Furthermore, so long as the Lease
has not been terminated, the Pass Through Trustee, the Subordination Agent,
the Indenture Trustee, the Owner Participant and the Owner Trustee hereby
agree for the benefit of Lessee that without Lessee's consent, each such
party will not amend any other provision of any Operative Document or Pass
Through Document in a manner adversely affecting Lessee. Each of the Owner
Participant, the Indenture Trustee, the Subordination Agent, the Pass
Through Trustee and the Owner Trustee agree to promptly furnish to Lessee
copies of any supplement, amendment, waiver or modification of any of the
Operative Documents or Pass Through Documents to which Lessee is not a
party. Each Loan Participant agrees that it will not take any action in
respect of the Trust Indenture Estate except through the Indenture Trustee
pursuant to the Trust Indenture or as otherwise permitted by the Trust
Indenture.

        SECTION 10.   CERTAIN COVENANTS OF LESSEE.  Lessee covenants and
agrees with each of the Loan Participants, the Owner Participant, the
Indenture Trustee and the Owner Trustee, as follows:

               (a) Further Assurances. Lessee will cause to be done,
executed, acknowledged and delivered all and every such further acts,
conveyances and assurances as the Owner Trustee, the Indenture Trustee or
the Owner Participant shall reasonably require for accomplishing the
purposes of this Agreement and the other Operative Documents; provided that
any instrument or other document so executed by Lessee will not expand any
obligations or limit any rights of Lessee in respect of the transactions
contemplated by any Operative Documents. Lessee, forthwith upon delivery of
the Aircraft under the Lease, shall cause the Aircraft to be duly
registered, and at all times thereafter to remain duly registered, in the
name of the Owner Trustee, except as otherwise required or permitted
hereunder or under the Lease, under the Transportation Code, or shall
furnish to the Owner Trustee such information as may be required to enable
the Owner Trustee to make application for such registration (at the expense
of Lessee), and shall promptly furnish to the Owner Trustee such
information as may be required to enable the Owner Trustee to timely file
any reports required to be filed by it as the lessor under the Lease or as
the owner of the Aircraft with any governmental authority (including tax
authorities).

               (b) Filings. Lessee, at its expense, will cause the Lease,
all Lease Supplements, all amendments to the Lease, the Trust Indenture,
all supplements and amendments to the Trust Indenture and this Agreement to
be promptly filed and recorded, or filed for recording, to the extent
permitted under the Transportation Code, or required under any other
applicable law. Upon the execution and delivery of the FAA Bill of Sale,
the Lease, the Lease Supplement covering the Aircraft, the Trust Supplement
and the Trust Indenture shall be filed for recording with the Federal
Aviation Administration in the following order of priority; First, the FAA
Bill of Sale, Second, the Lease, with the Lease Supplement covering the
Aircraft, the Trust Indenture and the Trust Supplement attached, and Third,
the Trust Indenture, with the Trust Supplement attached.

        SECTION 11.    OWNER FOR FEDERAL TAX PURPOSES.  It is the intent of
the parties to this Agreement that the Lease be treated as a true lease,
the Owner Participant be treated as the owner of the Aircraft to be
delivered under the Lease, and Lessee be treated as the lessee thereof for
Federal income tax purposes.

        SECTION 12.   NOTICES; CONSENT TO JURISDICTION.

               (a) Notices. All notices, demands, instructions and other
communications required or permitted to be given to or made upon any party
hereto shall be in writing and shall be personally delivered or sent by
registered or certified mail, postage prepaid, or by telecopier, or by
prepaid courier service, and shall be deemed to be given for purposes of
this Agreement on the day that such writing is delivered to the recipient
thereof in accordance with the provisions of this Section 12(a). Unless
otherwise specified in a notice sent or delivered in accordance with the
foregoing provisions of this Section 12(a), notices, demands, instructions
and other communications in writing shall be given to or made upon the
respective parties hereto at their respective addresses (or to their
respective telecopier numbers) as follows: (A) if to Lessee, the Owner
Trustee, the Pass Through Trustee, the Subordination Agent, the Indenture
Trustee or the Owner Participant, to the respective addresses set forth on
Schedule I hereto, or (B) if to a subsequent Owner Participant, addressed
to such subsequent Owner Participant at such address as such subsequent
Owner Participant shall have furnished by notice to the parties hereto, or
(C) if to any subsequent Note Holder, addressed to such Note Holder at its
address set forth in the Equipment Note register maintained pursuant to
Section 2.07 of the Trust Indenture.

               (b) Consent to Jurisdiction. Each of the parties hereto (A)
hereby irrevocably submits itself to the non-exclusive jurisdiction of the
United States District Court for the Southern District of New York and to
the non-exclusive jurisdiction of the Supreme Court of the State of New
York, New York County, for the purposes of any suit, action or other
proceeding arising out of this Agreement, the Lease, the Tax Indemnity
Agreement or any other Operative Document, the subject matter of any
thereof or any of the transactions contemplated hereby or thereby brought
by any party or parties thereto, or their successors or assigns and (B)
hereby waives, and agrees not to assert, by way of motion, as a defense, or
otherwise, in any such suit, action or proceeding, to the extent permitted
by applicable law, that the suit, action or proceeding is brought in an
inconvenient forum, that the venue of the suit, action or proceeding is
improper, or that this Agreement, the Lease, the Tax Indemnity Agreement or
any other Operative Document or the subject matter of any thereof or any of
the transactions contemplated hereby or thereby may not be enforced in or
by such courts; provided, however that the foregoing shall not apply to the
right any party may have to seek removal of such suit, action or proceeding
to federal court or to seek consolidation of any separate actions, suits or
proceedings brought by one or more of the other parties in the same or
different jurisdictions. The agreement set forth in this Section 12(b) is
given solely for the benefit of the parties hereto and shall not inure to
the benefit of any other Person.

        SECTION 13. CHANGE OF SITUS OF OWNER TRUST. The Owner Participant
agrees that if, at any time, the Trust Estate becomes subject to any Taxes
for which it is indemnified pursuant to Section 6(b) hereof and if, as a
consequence thereof, Lessee should request that the situs of the trust be
moved to another state in the United States from the state in which it is
then located, the situs of the trust may be moved and the Owner Participant
will take whatever action may be reasonably necessary to accomplish such
removal; provided that (A) Lessee shall provide such additional tax
indemnification as the Owner Participant and the Indenture Trustee may
reasonably request, (B) the rights and obligations under the Operative
Documents of the Owner Participant and the Indenture Trustee shall not be
altered as a result of the taking of such action, (C) the lien of the Trust
Indenture on the Trust Indenture Estate shall not be adversely affected by
such action and (D) the Owner Participant and the Indenture Trustee shall
have received an opinion or opinions of counsel (reasonably satisfactory to
the Owner Participant), in scope, form and substance satisfactory to the
Owner Participant to the effect that (I) the trust, as thus removed, shall
remain a validly established trust, (II) any amendments to the Trust
Agreement necessitated by such removal shall have been duly authorized,
executed and delivered by the parties thereto and shall constitute the
valid and binding obligations of such parties, enforceable in accordance
with their terms, (III) such removal will not result in the imposition of,
or increase in the amount of, any Tax for which Lessee is not required to
indemnify the Owner Participant, the Indenture Trustee, the Owner Trustee
or the Trust Estate pursuant to Section 6(b) hereof (taking into account
any additional indemnification provided by Lessee pursuant to clause (A) of
this sentence) and (IV) if such removal involves the replacement of the
Owner Trustee, an opinion of counsel to such successor Owner Trustee in
form and substance reasonably satisfactory to the Owner Participant
covering the matters described in the opinion delivered pursuant to Section
4(a)(xiii) and such other matters as the Owner Participant may reasonably
request and (E) Lessee shall indemnify and hold harmless the Owner
Participant and the Indenture Trustee on a net after-tax basis against any
and all reasonable and actual costs and expenses including reasonable
counsel fees and disbursements, registration fees, recording or filing fees
and taxes incurred by the Owner Trustee, the Owner Participant and the
Indenture Trustee in connection with such change of situs. Notwithstanding
anything to the contrary contained herein or in any other Operative
Document, the Owner Participant agrees with Lessee that it will not consent
to or direct a change in the situs of the Trust Estate without the prior
consent of Lessee unless the Owner Trustee, the Indenture Trustee, the Note
Holders and the Trust Estate each waives its right to any indemnity payable
by the Lessee under Section 6(b) as a result of the change in situs.


        SECTION 14.   MISCELLANEOUS.

               (a) Consents Under Lease. The Owner Participant covenants
and agrees that it shall not unreasonably withhold its consent to any
consent requested of the Owner Trustee, as Lessor, under the terms of the
Lease which by its terms is not to be unreasonably withheld by the Owner
Trustee, as Lessor.

               (b) Survival. The representations, warranties, indemnities
and agreements of Lessee, the Owner Trustee, the Indenture Trustee, the
Subordination Agent, the Pass Through Trustee and the Owner Participant
provided for in this Agreement or any other Operative Document, and
Lessee's, the Owner Trustee's, the Indenture Trustee's, the Subordination
Agent's, the Pass Through Trustee's and the Owner Participant's obligations
under any and all thereof, shall survive the making available of the
respective Commitments by the Pass Through Trustee and the Owner
Participant, the delivery or return of the Aircraft, the transfer of any
interest of the Owner Participant in the Trust Estate or the Aircraft or
any Engine or the transfer of any interest by any Loan Participant in any
Equipment Note or the Trust Indenture Estate and the expiration or other
termination of this Agreement or any other Operative Document.

               (c) Counterparts. This 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.

               (d) Amendments and Waivers. Neither this Agreement nor any
of the terms hereof may be terminated, amended, supplemented, waived or
modified, except by an instrument in writing signed by the party against
which the enforcement of the termination, amendment, supplement, waiver or
modification is sought; and no such termination, amendment, supplement,
waiver or modification shall be effective unless a signed copy thereof
shall have been delivered to the Indenture Trustee and the Owner Trustee.

               (e) Successors and Assigns. The terms of this Agreement
shall be binding upon, and inure to the benefit of, Lessee and, subject to
the terms of this Agreement, its successors and permitted assigns, the Pass
Through Trustee and its successors as Pass Through Trustee (and any
additional trustee appointed) under any of the Pass Through Trust
Agreements, the Owner Participant and, subject to the terms of this
Agreement, its successors and permitted assigns, each Note Holder and its
successors and registered assigns, the Indenture Trustee and its successors
as Indenture Trustee under the Trust Indenture and the Owner Trustee and
its successors as Owner Trustee under the Trust Agreement. The terms of
this Agreement shall inure to the benefit of the Liquidity Provider and
Policy Provider, and each of their successors and permitted assigns.

               (f)  Governing Law.  THIS AGREEMENT SHALL IN ALL RESPECTS
                    -------------
BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS
OF THE STATE OF NEW YORK, INCLUDING ALL MATTERS OF CONSTRUCTION, VALIDITY
AND PERFORMANCE.

               (g) Trust Capacity. The parties hereto agree that all of the
statements, representations, covenants and agreements made by the Owner
Trustee (when made in such capacity) contained in this Agreement and any
agreement referred to herein other than the Trust Agreement, unless
expressly otherwise stated, are made and intended only for the purpose of
binding the Trust Estate and establishing the existence of rights and
remedies which can be exercised and enforced against the Trust Estate.
Therefore, anything contained in this Agreement or such other agreements to
the contrary notwithstanding (except for any express provisions that the
Owner Trustee is responsible for in its individual capacity), no recourse
shall be had with respect to this Agreement or such other agreements
against the Owner Trustee in its individual capacity or against any
institution or Person which becomes a successor trustee or co-trustee or
any officer, director, trustee, servant or direct or indirect parent or
controlling Person or Persons of any of them; provided, however, that this
Section 14(g) shall not be construed to prohibit any action or proceeding
against any party hereto for its own willful misconduct or grossly
negligent conduct for which it would otherwise be liable; and provided,
further, that nothing contained in this Section 14(g) shall be construed to
limit the exercise and enforcement in accordance with the terms of this
Agreement or such other agreements of rights and remedies against the Trust
Estate. The foregoing provisions of this Section 14(g) shall survive the
termination of this Agreement and the other Operative Documents.

               (h) Section 1110. It is the intention of the parties hereto
that the Owner Trustee, as Lessor under the Lease, and the Indenture
Trustee, as assignee of such Owner Trustee's rights under the Lease
pursuant to the Trust Indenture, will be entitled to the benefits of 11
U.S.C. Section 1110 in the event of any reorganization of Lessee under such
Section.

        SECTION 15.   EXPENSES.

               (a) Invoices And Payment. Each of the parties hereto shall
promptly submit to the Owner Trustee and Lessee for their prompt approval
(which shall not be unreasonably withheld) copies of invoices in reasonable
detail of the Transaction Expenses for which it is responsible for
providing information as they are received. The Owner Participant agrees to
transfer to the Owner Trustee promptly such amount as shall be necessary in
order to enable the Owner Trustee to pay, or if previously paid by Lessee,
to reimburse Lessee for, Transaction Expenses. To the extent of funds
received by it, the Owner Trustee agrees to pay all invoices of Transaction
Expenses that have been approved by it and Lessee promptly upon receipt
thereof and, to the extent such invoices have previously been paid by
Lessee, to reimburse Lessee promptly therefor. Notwithstanding the
foregoing, to the extent that Transaction Expenses exceed __% of Lessor's
Cost, Lessee at its sole option shall have the right to pay directly any or
all Transaction Expenses which are in excess of __% of Lessor's Cost.

               (b) Payment of Other Expenses. In the event that the
transaction contemplated by this Participation Agreement fails to close as
a result of the Owner Participant's failure to negotiate in good faith or
to comply with the terms and conditions upon which its participation in the
transaction was predicated, the Owner Participant will be responsible for
all of its fees and expenses, including but not limited to the fees,
expenses and disbursements of its special counsel.

        SECTION 16.    REFINANCINGS.

               (a) Refinancing Generally. So long as no Lease Event of
Default shall have occurred and be continuing, Lessee shall have the right
to refinance all (but not less than all) of the Equipment Notes no more
than three times by giving written notice to the Owner Participant and the
Owner Trustee that there shall be effected a voluntary redemption of the
Equipment Notes by the Owner Trustee, whereupon the Owner Participant
agrees to negotiate promptly in good faith to conclude an agreement with
Lessee as to the terms of such refinancing operation (including the terms
of any debt to be issued in connection with such refinancing); provided
that no such refinancing shall require an increase in the amount of the
Owner Participant's investment in the beneficial ownership of the Aircraft
or in the principal amount of the Equipment Notes; and provided further
that the Owner Participant may reject any terms that, in its reasonable
judgment, materially and adversely affect the Owner Participant.

               Upon such agreement:

                      (1) within ten (10) Business Days after the reaching
               of such agreement, the Owner Participant will deliver to
               Lessee a certificate of an authorized representative of the
               Owner Participant (the "Refinancing Certificate") setting
               forth (i) (based upon information provided by Lessee and on
               the agreement reached between Lessee and the Owner
               Participant) the proposed date on which the outstanding
               Equipment Notes will be redeemed and a description of any
               new debt to be issued and the other aspects of such
               refinancing that will be consummated (such date, the
               "Refinancing Date") and (ii) the following information
               calculated pursuant to the provisions of paragraph (6) of
               this Section 16(a): (A) the proposed adjusted debt/equity
               ratio, (B) the principal amount of debt to be issued by the
               Owner Trustee on the Refinancing Date, (C) the amount, if
               any, by which the Owner Participant's aggregate investment
               in the beneficial interest in the Aircraft is to be
               decreased and (D) the proposed revised schedules of Basic
               Rent percentages, debt amortization, EBO Amount, Termination
               Value percentages and other purchase option or termination
               percentages. The Refinancing Certificate shall not provide
               for a debt/equity ratio of more than [_:1]. Within fourteen
               days of its receipt of the Refinancing Certificate, Lessee
               may demand a verification pursuant to Exhibit E to the Lease
               of the information set forth in the Refinancing Certificate.
               Upon the acceptance by Lessee of the accuracy of the
               information set forth in the Refinancing Certificate (or the
               determination pursuant to such verification procedures), as
               to the debt/equity ratio, the principal amount of debt to be
               issued by the Owner Trustee on the Refinancing Date and the
               revised Basic Rent percentages, debt amortization, EBO
               Amount, Termination Value percentages and other buyout and
               termination percentages (such information, whether as set
               forth or as so determined, the "Refinancing Information")
               the appropriate parties will take the actions specified in
               paragraphs (2) through (5) below;

                      (2) the appropriate parties will enter into
               appropriate documentation (which may involve an underwriting
               agreement in connection with such sale or the sale of the
               Owner Trustee's interest in the Trust Estate and/or the
               Aircraft and its resale to the Owner Trustee) with the
               institution or institutions to be named therein providing
               for (A) (i) the issuance and sale by the Owner Trustee to
               such institution or institutions on the Refinancing Date of
               debt securities in an aggregate principal amount specified
               in the Refinancing Information which amount shall be equal
               to the aggregate principal amount of all Equipment Notes
               outstanding on the Refinancing Date (such debt securities,
               the "New Debt") except that the principal amount of New Debt
               may exceed the principal amount of all outstanding Equipment
               Notes in connection with the first refinancing under this
               Section 16, (ii) the application of the proceeds of the sale
               of the New Debt to the redemption of all such Equipment
               Notes on the Refinancing Date and (iii) the payment of the
               excess, if any, of such proceeds over the amounts necessary
               to effect such redemption to the Owner Trustee and (B)
               pursuant to which the parties to the refinancing transaction
               (including the Owner Participant, the Lessee, the Owner
               Trustee and the Loan Participants, but excluding the holders
               of the Pass Through Certificates) make such representations,
               warranties and covenants as Lessee and Owner Participant
               reasonably require;

                      (3) Lessee shall give the notice to the Indenture
               Trustee pursuant to Section 2.11 of the Trust Indenture, and
               Lessee and the Owner Trustee will amend the Lease to provide
               that (i) Basic Rent payable in respect of the period from
               and after the Refinancing Date shall be as provided in the
               Refinancing Information and (ii) amounts payable in respect
               of EBO Amount and Termination Value from and after the
               Refinancing Date shall be as provided in the Refinancing
               Information;

                      (4) the Owner Trustee will enter into an agreement to
               provide for the securing thereunder of the New Debt in like
               manner as the Equipment Notes and will enter into such
               amendments and supplements to the Trust Indenture (or such
               new indenture or other security agreement) as may be
               necessary to effect such refinancing;

                      (5) the Lessee shall pay all of the reasonable
               expenses of such refinancing (including, but not limited to,
               the reasonable fees, expenses and disbursements of counsel
               and any placement or underwriting fees); and

                      (6) when calculating any of the information required
               to be set forth in a Refinancing Certificate, the Owner
               Participant shall make such calculations in a manner which
               (A) maintains the Owner Participant's Net Economic Return
               (except to the extent the assumptions referred are the
               subject of the recalculations being conducted by the Owner
               Participant) and (B) minimizes the Net Present Value of
               Rents to Lessee to the extent possible consistent with
               clause (A).

               (b) Limitation on Redemption. The Equipment Notes shall not
be subject to voluntary redemption by the Owner Trustee without the consent
of Lessee except as set forth in Section 2.14 of the Trust Indenture.



               IN WITNESS WHEREOF, the parties hereto have caused this
Agreement to be duly executed by their respective officers thereunto duly
authorized as of the day and year first above written.

signatures, including indorsements, the legal capacity of natural persons,
the authenticity of all documents submitted to us as originals, the
conformity to original documents of all copies submitted to us as

Office, the "New York Filing Office" and such financing Statements, the
"New York Financing Statement");

to your attention that certain of the Operative Documents are governed by
laws of jurisdictions other than those described above and we express no

- --------
1    For transactions involving subleases to Shuttle, include a reference
     to Shuttle Sublease.

                Capitalized terms not otherwise defined herein have the
meanings assigned thereto in Annex A to the Participation Agreement. The
documents referred to in (a) through (d), (g) through (h), (j), (l) and (m)
above shall hereinafter be referred to collectively as the "Transaction
Documents". The documents referred to in (e) and (f) above shall
hereinafter be referred to collectively as the "Indenture Documents."
"Applicable Laws" shall mean those laws, rules, regulations which, in our
experience, are normally applicable to transactions of the type
contemplated by the Transaction Documents, the Indenture Documents and the
Equipment Notes, without our having made any special investigation as to
the applicability of any special law, rule or regulation, and which are not
the subject of a specific opinion herein referring to a particular law or
laws. "Governmental Approval" means any consent, approval, license,
authorization or validation of, or filing, recording or registration with,
any governmental authority pursuant to Applicable Laws. Unless otherwise
indicated, the "New York UCC" means the Uniform Commercial Code as in
effect on the date hereof in the State of New York.

               Based upon the foregoing, and subject to the limitations,
qualifications, exceptions and assumptions set forth herein, we are of the
opinion that:

               3. Each of the Transaction Documents constitutes the valid
and binding obligation of US Airways enforceable against US Airways in
accordance with its terms under the laws of the State of New York. Each of
the Indenture Documents constitutes the valid and binding obligation of
each of the parties thereto, enforceable against each such party in
accordance with its terms under the laws of the State of New York.

               5. Neither the execution and delivery by US Airways of the
Transaction Documents nor the compliance by US Airways with the terms and
provisions thereof will contravene any Applicable Law of the State of New
York or any Applicable Law of the United States of America.

               7. Except for (a) the due and timely filing and, where
appropriate, recording of (i) the FAA Bill of Sale, (ii) the Trust
Agreement, (iii) the Lease (with the Lease Supplement covering the
Aircraft, the Indenture and the Trust Supplement covering the Aircraft
attached as exhibits) and (iv) the Trust Indenture (with the Trust
Supplement covering the Aircraft attached as an exhibit), pursuant to the
Transportation Code, (b) the registration of the issuance and sale of the
Pass Through Certificates under the Securities Act, (c) compliance with the
securities law of each applicable state and (d) filing of appropriate UCC
Financing Statements and continuation statements, no Governmental Approval,
which has not been obtained or taken and is not in full force and effect,
is required in connection with the execution, delivery or enforceability by
US Airways of any of the Transaction Documents.

               9. No registration of US Airways or any of the Pass Through
Trusts under the Investment Company Act of 1940, as amended, is required.

               11. The Equipment Notes, when issued to and acquired by the
Pass Through Trustee, will be valid and binding obligations of the Owner
Trustee enforceable against the Owner Trustee in accordance with their
terms and the terms of the Trust Indenture, as supplemented by the Trust
Supplement, and will be entitled to the benefits of the Trust Indenture, as
supplemented by the Trust Supplement.

               13. The provisions of the Trust Indenture, as supplemented
by the Trust Supplement, are effective to create, in favor of the Indenture
Trustee to secure the Secured Obligations, a valid security interest in the
Owner Trustee's rights in that portion of the collateral described therein
which is subject to Article 9 of the New York UCC (the "UCC Collateral").

               15. If the Lease and any Lease Supplement constitute
"chattel paper" within the meaning of Section 9-105 of the New York UCC (as
to which we express no opinion) then the security interest of the Indenture
Trustee therein will be perfected under the New York UCC upon the Indenture
Trustee taking possession of each original counterpart thereof in the State
of New York.

               17. The New York Financing Statement is in appropriate form
for filing in the New York Filing Office. To the extent that the New York
UCC governs the perfection of a security interest in the Owner Trustee's
rights in the UCC Collateral, as to which we express no opinion, the
security interest in favor of the Indenture Trustee in the UCC Collateral
described in the New York Financing Statement will be perfected upon filing
of the New York Financing Statement in the New York Filing Office.

               Our opinions in paragraphs 6, 7 and 8 with respect to the
security interest of the Indenture Trustee are subject to the following
qualifications:

               (b) We have assumed the Owner Trustee owns, or with respect
to after-acquired property will own, the UCC Collateral, and we express no
opinion as to the nature or extent of the Owner Trustee's rights in or
title to any of the UCC Collateral, and we note that with respect to
after-acquired property, the security interest will not attach until US
Airways acquires ownership thereof.

               (d) Our opinions with respect to the validity and perfection
of the security interest of the Indenture Trustee is limited to Article 9
of the New York UCC, and such opinions do not address (i) laws of
jurisdictions other than New York, and of New York except for Article 9 of
the UCC, (ii) collateral of a type not subject to Article 9 of the
Applicable UCC, and (iii) what law governs perfection or priority of the
security interests granted in the collateral covered by this opinion.

               (f) We call your attention that under the UCC, events
occurring subsequent to the date hereof may affect any security interest
subject to the UCC including, but not limited to, factors of the type
identified in Section 9-306 with respect to proceeds; Section 9-103 with
respect to changes in the location of the collateral and the location of a
debtor; and Sections 9-307, 9-308 and 9-309 with respect to subsequent
purchasers of the collateral. In addition, actions taken by a secured party
(e.g., releasing or assigning the security interest, delivering possession
of the collateral to a debtor or another person and voluntarily
subordinating a security interest) may affect any security interest subject
to the UCC.

               (h) We express no opinion with respect to the priority of
the security interest of the Indenture Trustee.

               (j) We call to your attention that with respect to any goods
which is an accession to, or commingled or processed with other goods, the
security interest of the Indenture Trustee may be limited by Section 9-314
or 9-315 of the New York UCC.

               (l) In the case of any instrument, chattel paper, account or
general intangible which is itself secured by other property, we express no
opinion with respect to the Indenture Trustee's rights in and to such
underlying property.

               (n) In the case of chattel paper, accounts or general
intangibles, we call to your attention that the security interest of the
Indenture Trustee for the benefit of the Pass Through Trustee may be
subject to the rights of account debtors, claims and defenses of account
debtors and the terms of agreements with account debtors.

               (p) In the case of goods, we express no opinion regarding
the security interest of the Indenture Trustee for the benefit of the Pass
Through Trustee in any goods which are (i) an accession to, or commingled
or processed with other goods to the extent that the security interest of
the Indenture Trustee for the benefit of the Pass Through Trustee is
limited by Section 9-314 or 9-315 of the UCC or (ii) subject to a
certificate of title or a document of title.

               (r) We express no opinion regarding the security interest of
the Indenture Trustee for the benefit of the Pass Through Trustee in any
items which are subject to a statute, regulation or treaty of the United
States of America which provides for a national or international
registration or a national or international certificate of title for the
perfection of a security interest therein or which specifies a place of
filing different from the place specified in the UCC for filing to perfect
such security interest.

               (t) We express no opinion regarding the security interest of
the Indenture Trustee for the benefit of the Pass Through Trustee in any of
the UCC Collateral consisting of claims against any government or
governmental agency (including without limitation the United States of
America or any state thereof or any agency or department of the United
States of America or any state thereof).

               (v) We have assumed that if the Trust maintains any place of
business in the State of New York, then the Trust shall be deemed to do
business in more than one county in the State of New York.

               19. It is not necessary, in connection with the creation of
the beneficial interest of the Owner Participant in the Trust Estate under
the circumstances contemplated by the Participation Agreement to register
such beneficial interest under the Securities Act of 1933, as amended, or
to qualify the Trust Agreement or the Trust Indenture under the Trust
Indenture Act of 1939, as amended.

               21. The Indenture Trustee acting in behalf of the holders of
the Equipment Notes will be entitled to the benefits of Section 1110 of the
Bankruptcy Code with respect to the Aircraft if US Airways is a debtor in a
case under Chapter 11 of the Bankruptcy Code.

               23.  [US Airways, as lessor under the sublease to Shuttle, Inc.,
will be entitled to the benefits of Section 1110 of the Bankruptcy Code
with respect to the Aircraft if Shuttle, Inc. is a debtor in a case under
Chapter 11 of the Bankruptcy Code.]2

               With respect to our opinion[s] in paragraph[s] 10 [and 11], we
note that a 1998 decision, Western Pacific Airlines, Inc. v. GATX (In re
Western Pacific Airlines, Inc.), 219 B.R. 305, on rehearing, 221 B.R. 1 (D.
Colo. 1998), appeal dismissed as moot, vacatur denied, Boullioun Aircraft
Holding Co., Inc. v. Smith Management (In re Western Pacific Airlines,
Inc.), 1999 WL 459469 (10th Cir. July 7, 1999), ruled that Section 1110
does not apply in a case after the trustee timely makes the agreement
specified in Section 1110(a)(1)(A) and timely cures defaults outstanding as
of the date of the Chapter 11 petition or that occur during the first sixty
days of the case, with the result, among others, that the ability of a
lessor to exercise remedies based on a default that occurs after the first
sixty days of the Chapter 11 case would be subject to the automatic stay.
We believe that this decision construes Section 1110 in a manner that is
inconsistent with both the language of Section 1110 and the legislative
history explaining the purpose and operation of Section 1110. Accordingly,
we believe that the decision is an incorrect interpretation of Section
1110.

               In addition, with respect to our opinion[s] in paragraph[s]
10 [and 11], we have, with your consent, relied on the US Airways Opinion
(as defined below) to the effect that [each of] US Airways [and Shuttle,
Inc.] is a "citizen of the United States," as defined in Section 40102 of
Title 49 of the United States Code, and [each of US Airways and Shuttle,
Inc.] is the holder of an "air carrier operating certificate" issued by the
Secretary of Transportation (or by the Administrator of the FAA acting
under authority delegated by the Secretary of Transportation) pursuant to
Section 44705 (in Chapter 447) of the Transportation Code for aircraft
capable of carrying ten or more individuals or 6,000 pounds or more of
cargo. We have also assumed that where the Indenture Trustee is acting as
secured party, the security interest of the Indenture Trustee in the
Aircraft is perfected.

     Shuttle.

               Our opinions are subject to the following assumptions and
qualifications:

               (b) enforcement of the Transaction Documents and the
Indenture Documents may be limited by applicable bankruptcy, insolvency,
reorganization, moratorium or other similar laws affecting creditors'
rights generally and by general principles of equity (regardless of whether
enforcement is sought in equity or at law);

               (d) certain of the remedial provisions with respect to the
leased property including waivers with respect to the exercise of remedies
against the leased property contained in the Lease, may be unenforceable in
whole or in part, but the inclusion of such provisions does not affect the
validity of the Lease, taken as a whole, and the Lease, taken as a whole,
together with applicable law, contains adequate provisions for the
practical realization of the benefits thereof;

               (f) certain of the remedial provisions with respect to the
security including waivers with respect to the exercise of remedies against
the Trust Indenture Estate contained in the Trust Indenture, as
supplemented by the Trust Supplement, may be unenforceable in whole or in
part, but the inclusion of such provisions does not affect the validity of
each of the Trust Indenture, as supplemented by the Trust Supplement, taken
as a whole, and the Trust Indenture, as supplemented by the Trust
Supplement, taken as a whole, together with applicable law, contains
adequate provisions for the practical realization of the security thereof;

               (h) we express no opinion as to the effect on the opinions
expressed herein of (i) the compliance or non-compliance of any party
(without in any way limiting other qualifications and assumptions made
herein, other than US Airways) to the Transaction Documents or the
Indenture Documents with any state, federal or other laws or regulations
applicable to it or (ii) the legal or regulatory status or the nature of
the business of any such party;

               (j) we express no opinion as to the enforceability of any
rights to contribution or indemnification provided for in the Transaction
Documents or the Indenture Documents to the extent any such rights are
violative of the public policy (including, without limitation, the public
policy underlying any federal or state securities law, rule or regulation);

               (l) we express no opinion as to any provision of any
Transaction Document or any Indenture Document that provides a penalty or
to the extent that it provides for an absolute and unconditional obligation
to perform such Transaction Document even though such Transaction Document
or Indenture Document is invalid or terminated or such performance would be
illegal; and

               (n) with respect to our opinion that the New York choice of
law provision in the Transaction Documents and the Indenture Documents
which are expressly governed by New York law is enforceable, we rely upon,
among other things, the Act of July 19, 1984, Ch. 421, 1984 McKinney's
Sess. Laws of N.Y. 1406, (codified at N.Y. Gen. Oblig. Law ss.ss. 5-1401,
5-1402 (McKinney 1989) and N.Y. CPLR 327(b) (McKinney 1990) (the "Act"),
and our opinion is subject to the qualifications that such enforceability
(i) may be limited by public policy considerations of any jurisdiction,
other than the courts of the State of New York, in which enforcement of
such provisions, or of a judgement upon an agreement containing such
provisions, is sought, and (ii) as specified in the Act, does not apply to
the extent provided to the contrary in subsection two of Section 1-105 of
the Uniform Commercial Code for the State of New York.

               In rendering the foregoing opinions, we have assumed, with
your consent, that:

               (b) each of the Transaction Documents constitutes the legal,
valid and binding obligation of each party thereto (other than US Airways)
enforceable against each such party (other than US Airways) in accordance
with its terms;

               (d) each of (i) the Owner Participant, (ii) State Street
Bank and Trust Company of Connecticut, National Association, (iii) First
Security Bank, National Association, and (iv) US Airways is duly organized
and validly existing in good standing under the laws of the jurisdiction of
its organization;

               (f) each of (i) the Owner Participant, (ii) State Street
Bank and Trust Company of Connecticut, National Association, individually
and as Indenture Trustee, Subordination Agent and Pass Through Trustee,
(iii) First Security Bank, National Association, individually and as Owner
Trustee, and (iv) US Airways has full power, authority and legal right to
enter into and perform its respective obligations under, and consummate the
transactions contemplated by, each of the Transaction Documents and the
Indenture Documents to which it is a party;

               (h) each of (i) the Owner Participant, (ii) State Street
Bank and Trust Company of Connecticut, National Association, individually
and as Indenture Trustee, Subordination Agent and Pass Through Trustee,
(iii) First Security Bank, National Association, individually and as Owner
Trustee, and (iv) US Airways has duly authorized, executed and delivered
each of the Transaction Documents and the Indenture Documents to which it
is a party;

               (j) the execution, delivery and performance of the
Transaction Documents and the Indenture Documents by each of the parties
thereto and the consummation of the transactions contemplated thereby does
not and will not conflict with, contravene, violate or constitute a default
under (i) the respective certificate of incorporation, by-laws or other
organizational documents of any such party, (ii) any indenture, mortgage,
lease, agreement or other instrument to which any such party is a party or
by which it or any of its property may be bound or subject, (iii) any law,
rule or regulation of any jurisdiction (provided that we make no such
assumption with respect to Applicable Laws of the State of New York and
Applicable Laws of the United States of America insofar as such Applicable
Laws apply to US Airways, as to which we express our opinion in paragraph 2
herein) or (iv) any judicial or administrative order or decree of any
governmental authority;

               (l) except for (i) the due and timely filing and, where
appropriate, recording of (A) the FAA Bill of Sale, (B) the Trust
Agreement, (C) the Lease (with the Lease Supplement covering the Aircraft,
the Indenture and the Trust Supplement covering the Aircraft attached as
exhibits) and (D) the Trust Indenture (with the Trust Supplement covering
the Aircraft attached as an exhibit), pursuant to the Transportation Code,
(ii) the registration of the issuance and sale of the Pass Through
Certificates under the Securities Act, (iii) compliance with the securities
law of each applicable state and (iv) the filing of appropriate UCC
financing statements, no consent, license, permit or approval of, or giving
of notice to, or registration with, or taking of any action in respect of,
any governmental authority of any jurisdiction is required in connection
with (X) the execution, delivery and performance by any party to any
Transaction Document of the respective Transaction Documents to which it is
a party, (Y) the consummation of the transactions contemplated thereby or
(Z) the legality, validity or enforceability of the Transaction Documents
or the Indenture Documents with respect to any party to any Transaction
Document or any Indenture Document (provided that we make no such
assumption with respect to those required by Applicable Laws as such
Applicable Laws apply to US Airways); and

               (n) the Trust Agreement duly creates, for the benefit of the
Owner Participant, the trust interest in the trust estate which the Trust
Agreement by its terms purports to create and the trust purported to be
created by the Trust Agreement has been duly formed and is validly
existing.

        Re:    US Airways, Inc. Trust No.  N____U_
               -----------------------------------

Ladies and Gentlemen:

        I am the _________________________ of US Airways, Inc., a Delaware
corporation ("US Airways"), and am familiar with the transactions
contemplated by the Participation Agreement (US Airways, Inc. Trust No.
N___U_), dated as of ________, ____ (the "Participation Agreement"), among
US Airways, as Lessee, __________________, as Owner Participant, State
Street Bank and Trust Company of Connecticut, National Association, a
national banking association, not in its individual capacity except as
otherwise provided therein but solely as Pass Through Trustee, Indenture
Trustee and Subordination Agent, and First Security Bank, National
Association, a national banking association, not in its individual capacity
except as otherwise provided therein, but solely as Owner Trustee, relating
to the Aircraft (as defined below). Capitalized terms not otherwise defined
herein have the meanings assigned thereto in Annex A to the Participation
Agreement.

        This opinion is being delivered pursuant to Section 4(a)(xi) of the
Participation Agreement.

        In my examination, I have assumed the genuineness of all signatures
(other than the signatures made on behalf of US Airways), including
endorsements, the legal capacity of natural persons, the authenticity of
all documents submitted to me as originals, the conformity to original
documents of all copies submitted to me as telefacsimile, certified or
photostatic copies, and the authenticity of the originals of such copies.
As to any facts material to this opinion, I have relied solely upon
statements, representations and warranties of US Airways, the Owner
Participant, the Owner Trustee, the Indenture Trustee, the Subordination
Agent, the Pass Through Trustee and their respective officers and
representatives, and others in the Operative Documents and of public
officials, and I have made no independent investigation or inquiry with
respect to such factual matters.

        In rendering the opinions set forth herein, I have examined and
relied on executed originals or copies of the following:

        (a)  the Participation Agreement;

        (b)  the Lease;

        (c)  the Lease Supplement;

        (d)  the Tax Indemnity Agreement;

        (e)  the Purchase Agreement Assignment;

        (f)  the Trust Indenture;

        (g)  the Trust Supplement;

        (h)  the Warranty Bill of Sale;

        (i)  the FAA Bill of Sale;

        (j)  the Acceptance Certificate;

        (k)  the Equipment Notes;

        (l)  the Pass Through Trust Agreement;

        (m)  each of the Pass Through Trust Agreement Supplements;

        (n)  certified copies of the Certificate of Incorporation and By-laws
of US Airways;

        (o)  certified copies of certain resolutions of the Board of Directors
of US Airways adopted on May 18, 1999;

        (p) a certificate of good standing from the Secretary of State of
the State of Delaware as to the good standing of US Airways in such
jurisdiction [and a certificate of good standing from the Secretary of
State of the State of Delaware as to the good standing of Shuttle, Inc. in
such jurisdiction]; and

        (q) such other documents as I have deemed necessary or appropriate
as a basis for the opinions set forth below.

        Based on the foregoing and subject to the limitations,
qualifications, exceptions and assumptions set forth herein, it is my
opinion that:

        1. US Airways is a corporation duly incorporated, validly existing
and in good standing under the laws of the State of Delaware, is a "citizen
of the United States" within the meaning of Section 40102(a)(15) of the
Transportation Code, and has or had, on the date of execution thereof, the
corporate power and authority to carry on its business as currently
conducted and to enter into and perform its obligations under each of the
Operative Documents to which it is a party. US Airways is duly qualified to
do business and is in good standing in the Commonwealth of Virginia and
each other state of the United States in which its operations or the nature
of its business requires US Airways to so qualify, except where the failure
to so qualify would not have a material adverse effect on US Airways or its
business.

        2. US Airways possesses all necessary certificates, franchises,
licenses, permits, rights and concessions and consents which are material
to the operation of the routes flown by it and the conduct of its business
and operations as currently conducted, and each such certificate,
franchise, license, permit, right and concession and consent is in full
force and effect, except where any failure would not have a material
adverse effect on US Airways or its business.

        3. Each of the Operative Documents to which US Airways is a party
has or had, on the date of execution thereof, been duly authorized,
executed and delivered by US Airways.

        4. Neither the execution and delivery by US Airways of any of the
Operative Documents to which US Airways is a party, nor the consummation of
any of the transactions by US Airways contemplated thereby, nor the
performance of the obligations thereunder by US Airways, did at the time of
execution and delivery, or does presently (a) require any stockholder
approval or violate the Certificate of Incorporation or By-laws of US
Airways or (b) conflict with or contravene the provisions of, or constitute
a default under, or result in the creation of any Lien (other than any
Permitted Lien) upon the property of US Airways under any law, governmental
rule or regulation, or the Certificate of Incorporation or By-laws of US
Airways or any order, writ, injunction or decree of any court or
governmental authority against US Airways or by which any of its properties
may be bound or any material indenture, mortgage, contract or other
agreement known to me to which US Airways is a party or by which it may be
bound, or require the approval or consent of any trustee or the holders of
any indebtedness or material obligations of US Airways.

        5. Neither the execution and delivery by US Airways of any of the
Operative Documents to which it is a party, nor the consummation of any
transactions by US Airways contemplated thereby, nor the performance of the
obligations thereunder by US Airways, did or does, as the case may be, (a)
require the consent or approval of, the giving of notice to, or (except as
described or contemplated in the Operative Documents, all of which were or
are required to be performed on or prior to the Delivery Date and which
were or shall have been accomplished on or prior to the Delivery Date) the
registration with, or the taking of any other action in respect of, the
FAA, the Securities and Exchange Commission or any other authority or
agency of the federal government or of the State of Delaware other than (i)
the registration of the issuance and sale of the Pass Through Certificates
under the Securities Act, (ii) compliance with the securities laws of each
applicable state, (iii) the registration in the Owner Trustee's name of the
Aircraft pursuant to the Transportation Code, and (iv) the filings and,
where appropriate, recording, pursuant to the Transportation Code, of each
of the FAA Bill of Sale, the Trust Agreement, the Lease (with the Lease
Supplement covering the Aircraft attached as an exhibit) and the Trust
Indenture (with the Trust Supplement covering the Aircraft attached as an
exhibit), or (b) contravene any judgment or order applicable to or binding
on US Airways or any law or governmental rule or regulation of the United
States or of the State of Delaware.

        6. There is no pending or, to my knowledge, threatened action or
proceeding before any court or administrative agency which individually (or
in the aggregate in the case of any group of related lawsuits) (i) is
expected to have a material adverse effect on (A) the financial condition
of US Airways except for the matters described under "Legal Proceedings" in
US Airways' Annual Report on Form 10-K for the fiscal year ended December
31, ____ [and US Airways' Quarterly Report on Form 10-Q for the quarter
ended March 31, ____, June 30, ____, and September 30, ____, respectively],
as to all of which I can express no opinion at this time concerning US
Airways' liability (if any) or the effect of any adverse determination upon
the business, condition (financial or otherwise) or operations of US
Airways, or (B) the ability of US Airways to perform its obligations under
the Operative Documents, or (ii) involves the Aircraft.

        7. US Airways is a duly certificated "air carrier" within the
meaning of the Transportation Code, and a holder of a certificate under
Section 41102(a) of the Transportation Code. US Airways is the holder of an
"air carrier operating certificate" under Section 44705 of the
Transportation Code for aircraft capable of carrying ten (10) or more
individuals or 6,000 pounds or more of cargo, and such certificate is in
full force and effect.

        8. US Airways is not, and is not directly or indirectly controlled
by or acting on behalf of any Person which is, an "investment company"
within the meaning of the Investment Company Act of 1940, as amended.

        [9.    Shuttle, Inc. is a corporation duly incorporated, validly
existing and in good standing under the laws of the State of Delaware and
is a "citizen of the United States" within the meaning of Section
40102(a)(15) of the Transportation Code.]1

        [10.   Shuttle, Inc. is a duly certificated "air carrier" within the
meaning of the Transportation Code, and a holder of a certificate under
Section 41102(a) of the Transportation Code. Shuttle, Inc. is the holder of
an "air carrier operating certificate" under Section 44705 of the
Transportation Code for aircraft capable of carrying ten (10) or more

RE:   ONE AIRBUS A330-[   ] AIRCRAFT
      MANUFACTURER'S SERIAL NO.[   ]
      US REGISTRATION NO. [   ]


Dear Sirs,

1.    We have been requested by US Airways Inc. (the "COMPANY"), to act as
      special French counsel with respect to, and to render this opinion
      in connection with certain of the transactions contemplated in a
      certain Participation Agreement dated as of [        ] (the
      "PARTICIPATION AGREEMENT") among [         ].

2.    We have examined copies(1) (which we assume conform to the originals)
      of:
- -------------
(1)   AS OF THE DATE HEREOF WE HAVE NOT HAD SIGHT OF PRO-FORMA DOCUMENTS;
      THIS DRAFT OPINION IS BASED ON THE ASSUMPTION THAT THE DOCUMENTS WILL
      FOLLOW THE FORM OF THE 1999 EETC FINANCINGS.


      (i)   the purchase agreement assignment (Scheduled April, 2000
            through December, 2000 Deliveries) dated as of [      ] between
            US Airways Group, Inc. (as assignor) and the Company (as
            assignee) (the "FIRST PURCHASE AGREEMENT ASSIGNMENT");

      (ii)  the consent and agreement of AVSA S.A.R.L. ("AVSA") and Airbus
            Industrie G.I.E. ("AIRBUS") to the First Purchase Agreement
            Assignment as acknowledged and accepted by US Airways Group,
            Inc. and the Company dated as of [           ] (the "FIRST
            CONSENT");

      (iii) the purchase agreement assignment (US Airways, Inc. Trust No.
            N[ ]U[ ]), dated as of [        ], between the Company (as
            assignor) and State Street Bank and Trust Company of
            Connecticut, National Association (the "INDENTURE TRUSTEE") as
            assignee) (the "SECOND PURCHASE AGREEMENT ASSIGNMENT");

      (iv)  the consent and agreement of Airbus (to the Second Purchase
            Agreement Assignment) dated as of [     ] (the "AIRBUS CONSENT
            AND AGREEMENT");

      (v)   the consent and agreement of AVSA (to the Second Purchase
            Agreement Assignment) dated as of [      ] (the "AVSA CONSENT
            AND AGREEMENT");

      (vi)  the indenture and security agreement dated as of [      ]
            between the Company (as owner) and the Indenture Trustee (the
            "INDENTURE"); and

      (vii) a document executed both in the English language as the "FRENCH
            PLEDGE" and in the French language as the "ACTE DE NANTISSEMENT
            DE CREANCES" (the latter being a correct translation of the
            former) each dated [       ] and made between the Company (as
            pledgor) and the Indenture Trustee (as pledgee) collectively
            referred to herein as the "ACTE DE NANTISSEMENT",

      the First Purchase Agreement and the Second Purchase Agreement
      Assignment are together referred to herein as the "ASSIGNMENTS", the
      First Consent and the Second Consents are together referred to herein
      as the "CONSENTS" and the documents referred to in (i) to (vii) above
      are hereinafter referred to collectively as the "DOCUMENTS".

3.    In considering the above, we have assumed:

      (i)   that the Documents have been duly executed by the parties
            thereto (other than Airbus and AVSA);

      (ii)  the genuineness of all signatures;

      (iii) the completeness and conformity to the originals of all
            documents supplied to us as copies or as facsimiles;

      (iv)  that the Documents expressed to be governed by New York law
            constitute the legal, valid and binding obligations of the
            parties thereto under New York law.

4.    Having considered the Documents we are of the opinion, subject to the
      qualifications and reservations set out in paragraph 5 below, that:

      (i)   Airbus is a groupement d'interet economique duly organised and
            existing under the laws of the French Republic and has the
            power and authority to carry on its business as now conducted.
            The present members of Airbus are (i) Aerospatiale Matra S.A.,
            (ii) DaimlerChrysler Aerospace Airbus GmbH, (iii) British
            Aerospace (Operations) Ltd. and (iv) Construcciones
            Aeronauticas S.A. and each of such corporations is, without the
            need to proceed against any collateral security for the
            indebtedness of Airbus or to take any other legal action or
            process (except for service on Airbus by huissier of notice to
            perform and subsequent failure by Airbus to do so), jointly and
            severally liable with the other members for the debts of Airbus
            arising out of obligations contracted by Airbus while such
            corporation is a member of Airbus;

      (ii)  AVSA is a societe a responsabilite limitee duly established and
            existing under the laws of the French Republic and has the
            power and authority to carry on its business as now conducted;

      (iii) each of Airbus and AVSA has full power and authority to enter
            into and to execute, deliver and perform its obligations under
            the Documents to which it is a party; such obligations are
            legal, valid and binding upon them respectively, are
            enforceable in accordance with their respective terms and rank
            pari passu with the other unsecured obligations of Airbus and
            AVSA, as the case may be;

      (iv)  assuming that under New York law the Indenture Trustee would be
            entitled to take proceedings in its own name and on its own
            account to recover from the Company the full amount of all
            amounts secured by the Acte de Nantissement and subject to the
            registration and huissier requirements of paragraph 5(d) hereof
            and the observation set forth in paragraph 5(f) hereof, the
            Acte de Nantissement:

            (a) duly creates for the benefit of the Indenture Trustee the
                security interests which it purports to create and the
                Indenture Trustee is entitled to the benefits and security
                afforded thereby; and

            (b) would be effective as against Airbus, AVSA and third
                parties to perfect the pledge (nantissement) of the
                obligations of Airbus and AVSA that are the subject of the
                Acte de Nantissement;

      (v)   the choice of the laws of the State of New York to govern the
            Documents (which are expressed to be so governed) is valid
            under the laws of the French Republic, and a French court would
            uphold such choice of law in any suit on the Documents brought
            in a French court.

5.    This opinion must be read subject to the following qualifications and
      observations as to French law:

      (a)   the remedy of specific performance may not be available in a
            French court;

      (b)   in respect of payment obligations, a French court has power
            under Article 1244-1 of the French Civil Code to grant time to
            a debtor (not in excess of two years), taking into account the
            position of the debtor and the needs of the creditor;

      (c)   in order to ensure the validity as against third parties of the
            assignment made in the Assignments, it is necessary that notice
            of such assignments be served on Airbus and AVSA by huissier in
            accordance with the provisions of Article 1690 of the French
            Civil Code. [We have been instructed by the Company to assist
            in carrying out such formalities which we intend to do upon
            receipt of duly executed originals of such assignment and we
            anticipate that there will be no difficulty in accomplishing
            these formalities](2);

      (d)   in order to ensure the validity as against third parties of the
            pledge (nantissement) created by the Acte de Nantissement in
            accordance with the provisions of Article 2075 of the French
            Civil Code, it is necessary for the Acte de Nantissement to be
            registered with the French tax administration in a form duly
            translated in French by a sworn translator, involving payment
            of a stamp duty of a nominal amount. In addition, the pledge
            (nantissement) created by the Acte de Nantissement will need to
            be served on each of the obligors by huissier, in accordance
            with the provisions of Article 2075 of the French Civil Code.
            [We have been instructed by the Company to carry out such
            formalities on its behalf which we intend to do upon receipt of
            duly executed originals of the Pledge Agreement and we
            anticipate that there will be no difficulty in accomplishing
            these formalities](2);

(2)   NOTE: US AIRWAYS TO CONFIRM INSTRUCTIONS


      (e)   in the event o any proceedings being brought in a French court
            in respect of a monetary obligation expressed to be payable in
            a currency other than French Francs or euros, a French court
            would probably give judgment expressed as an order to pay, not
            such currency, but its French Franc or euro equivalent at the
            time of payment or enforcement of judgment. With respect to a
            bankruptcy, insolvency, liquidation, moratorium,
            reorganisation, reconstruction or similar proceedings, French
            law may require that all claims or debts be converted into
            French Francs or euros at an exchange rate determined by the
            court at a date related thereto, such as the date of
            commencement of a winding-up;

      (f)   pledges over non-monetary claims are unusual under French law.
            In principal, pledges over claims of this type should be
            effective against Airbus, AVSA and third parties but in the
            absence of case law, there is a lack of certainty about the
            pledge being effective;

      (g)   a determinatio or certificate as to any matter provided for in
            the Documents might be held by a French court not to be final,
            conclusive or binding, if such determination or certificate
            could be shown to have an unreasonable, incorrect or arbitrary
            basis or not to have been given or made in good faith;

      (h)   claims may become barred by effluxion of time or may be or
            become subject to defence of set-off or counterclaim;

      (i)   a French court may stay proceedings if concurrent proceedings
            are being brought elsewhere;

      (j)   we express no opinion as to whether any provision in the
            documents conferring a right of set-off or similar right would
            be effective against a liquidator or a creditor;

      (k)   the enforcemen against Airbus of any of the Documents to which
            it is a party may be limited by applicable bankruptcy,
            insolvency, arrangement, moratorium or similar laws relating to
            or affecting the enforcement of creditors' rights generally, as
            such laws are applied to Airbus. The enforcement against AVSA
            of any of the Documents to which it is a party may be limited
            to such laws, as such laws are applied to AVSA. The enforcement
            against any member of Airbus of any obligation of Airbus
            contained in the Documents may be limited to such laws, as such
            laws are applied to such member;

      (l)   our opinion as to the enforceability of the Documents relates
            only to their enforceability in France in circumstances where
            the competent French court has and accepts jurisdiction. The
            term "enforceability" refers to the legal character of the
            obligations assumed by the parties under the Documents, i.e.
            that they are of a character which French law enforces or
            recognises. It does not mean that the Documents will be
            enforced in all circumstances or in foreign jurisdictions or by
            or against third parties or that any particular remedy will be
            available; and

      (m)   article 899 of the French Tax Code provides that agreements
            evidencing an undertaking to pay a sum of money are subject to
            stamp tax (droit de timbre) of a nominal amount if made in the
            French Republic, if made in a foreign country, such agreements
            are subject to a stamp tax of a nominal amount before certain
            use thereof can be made in the French Republic (Article 897 of
            the French Tax Code). However non-payment of such stamp tax
            does not affect the legality, validity or enforceability of the
            Documents.

We are qualified as French Avocats.

No opinion is expressed herein as to laws other than the laws of the French
Republic as of the date hereof. This opinion is for your use and that of no
one else, and is limited to (i) the matters specifically mentioned herein,
and (ii) the purpose set out above.

Yours faithfully,

 TO EACH OF THE PARTIES SET FORTH
 IN SCHEDULE A HERETO:

 Re:  US AIRWAYS, INC. LEVERAGED LEASE N____

      Dear Sir or Madam:

      We have acted as special counsel for First Security Bank, National
 Association, a national banking association, in its individual capacity
 ("First Security") and in its capacity as trustee (the "Owner Trustee")
 under Trust Agreement ___ dated as of __________, 2000, (the "Trust
 Agreement") between it and ____________, as owner participant (the "Owner
 Participant"), in connection with the transactions contemplated by the
 Participation Agreement (as defined below).  We are delivering this opinion
 at the request of First Security.  Except as otherwise defined herein, the
 terms used herein shall have the meanings set forth in Annex A to
 Participation Agreement ___, dated as of ____________, 2000 among US
 Airways, Inc., as Lessee, the Owner Participant, First Security, not in its
 individual capacity except as provided therein, and as Owner Trustee, and
 State Street Bank and Trust Company of Connecticut, National Association,
 not in its individual capacity except as expressly provided therein, but
 solely as Indenture Trustee, Subordination Agent and as Pass Through
 Trustee under each of the Pass Through Trust Agreements (the "Participation
 Agreement").

 We have examined originals or copies, certified or otherwise identified to
 our satisfaction, of such documents, corporate records and other
 instruments as we have deemed necessary or advisable for the purpose of
 rendering this opinion.

 Based upon the foregoing, we are of the opinion that:

           (1)  First Security is a national banking association duly
      organized, validly existing and in good standing under the laws of the
      United States, is a "citizen of the United States" within the meaning
      of Section 40102(a)(15) of the Act and has the full power and
      authority to enter into and perform its obligations under the Trust
      Agreement and each other Operative Agreement to which it, in its
      individual capacity or as Owner Trustee, as the case may be, is a
      party and, as Owner Trustee, to issue, execute, and deliver and
      perform the Equipment Notes.

           (2)  The Owner Trustee is the duly appointed trustee under the
      Trust Agreement and the Trust Agreement creates a legal and valid
      trust under the laws of the State of Utah; the trust created by the
      Trust Agreement has been duly created and exists for the benefit of
      the Owner Participant, and the Trust Agreement creates for the benefit
      of the Owner Participant the rights and interests in the Trust Estate
      which the Trust Agreement by its terms purports to create; and
      assuming the Trust Agreement was properly authorized, executed and
      delivered by the Owner Participant and that the terms of the Trust
      Agreement are not in violation of any laws, documents, judgments,
      regulations or other provisions applicable to the Owner Participant,
      the Trust Agreement constitutes, under the laws of the State of Utah,
      a legal, valid and binding obligation of the Owner Participant
      enforceable against the Owner Participant in accordance with its
      terms.

           (3)  The Trust Agreement, the Participation Agreement, and each
      other Operative Agreement to which First Security or the Owner
      Trustee, as the case may be, is a party, and the Equipment Notes, have
      been duly authorized, executed and delivered by First Security, or the
      Owner Trustee, as the case may be, and assuming due authorization,
      execution and delivery by the other parties thereto is a legal, valid
      and binding obligation of First Security, or the Owner Trustee, as the
      case may be, enforceable in accordance with their respective terms.

           (4)  The execution and delivery by First Security of the Trust
      Agreement and the Participation Agreement and the execution and
      delivery by the Owner Trustee of the Operative Agreements to which it
      is a party is not, and the performance by First Security, or the Owner
      Trustee, as the case may be, of its respective obligations under each
      such agreements will not be, inconsistent with the articles of
      association or by-laws of First Security, do not and will not
      contravene any federal law or law of the State of Utah, or any rule or
      regulation of the State of Utah or the federal government, or any
      judgment or order of which we have knowledge and which is applicable
      to it and do not and will not contravene any provision of, or result
      in the creation of any lien upon any property of First Security, or
      constitute a default under, any indenture, mortgage, contract or other
      instrument of which we have knowledge and to which First Security or
      the Owner Trustee is a party or by which either is bound or require
      the consent or approval of, the giving of notice to, or the
      registration with, or the taking of any action in respect of, or under
      federal law or the laws of the State of Utah or any subdivision or
      agency thereof.

           (5)  There are no fees, taxes or other charges, except taxes
      imposed on fees payable to First Security, required to be paid under
      the laws, ordinances or regulations of the State of Utah or any
      political subdivision thereof, including, without limitation, Salt
      Lake City, in connection with the execution, delivery or performance
      by the Lessee, Owner Trustee, Mortgagee or any Participant of the
      Operative Agreements solely because First Security, or the Owner
      Trustee as the case may be, performs certain of its obligations under
      the Operative Agreements in the State of Utah.

           (6)  There are no pending or, to our knowledge, threatened
      actions or proceedings against or affecting First Security or the
      Owner Trustee, as the case may be, before any court, governmental
      authority or administrative agency which, if adversely determined,
      could materially adversely affect the right, power or ability, either
      in its individual capacity or as Owner Trustee, or both, as the case
      may be, to enter into or perform its obligations under the Operative
      Agreements.

           (7)  The Trust Indenture (or financing statements or other
      notices with respect thereto) has been filed for record or recorded
      with the Division of Corporations and Commercial Code in the State of
      Utah and such offices are all  the places in the State of Utah wherein
      such filing or recordation is necessary and no other actions or
      filings are necessary in the State of Utah to perfect the lien and
      security interest of the Mortgagee in the Trust Estate as against
      creditors of or purchasers from the Owner Trustee or the Lessee, or
      both.

           (8)  The Owner Trustee has received such right, title and
      interest in and to the Aircraft as was conveyed to the Owner Trustee
      on the date hereof, subject to (i) the rights of the Lessee under the
      Lease and the Lease Supplement; (ii) the beneficial interest of the
      Owner Participant in the Aircraft; and (iii) the Lien created pursuant
      to the Trust Indenture and the Trust Indenture Supplement;  and to our
      knowledge there exist no Liens affecting the right, title or interest
      of the Owner Trustee in and to the Trust Estate resulting from claims
      against First Security, not related to the ownership of the Trust
      Estate or the administration of the Trust Estate or any other
      transaction contemplated by the Operative Agreements.

           (9)  Assuming that (i) the Aircraft is not physically located in
      the State of Utah at the commencement or termination of the Term, (ii)
      in connection with any sale or lease of the Aircraft, such Aircraft
      will not be physically delivered in the State of Utah, and (iii) the
      Aircraft will be sold or leased for use in interstate commerce, and
      (iv) the trust created by the Trust Agreement is treated as a grantor
      trust for federal income tax purposes in accordance with Sections 671
      through 678 of the Internal Revenue Code of 1986, as amended, there
      are no sales or transfer fees, taxes or other charges (except taxes
      imposed on fees payable to the Owner Trustee) payable to the State of
      Utah or any political subdivision thereof in connection with the
      execution, delivery or performance by the Owner Trustee, the
      Mortgagee, the Lessee or any Participant of the Operative Agreements
      or in connection with the making by the Owner Participant of its
      investment in the Aircraft or its acquisition of the beneficial
      interest in the Trust Estate or in connection with the issuance and
      acquisition of the Equipment Notes. Neither the Owner Trustee, the
      Trust Estate nor the trust created by the Trust Agreement will be
      subject to any fee, tax or other governmental charge (except taxes on
      fees payable to the Owner Trustee) under the laws of the State of Utah
      or any political subdivision thereof on, based on or measured by,
      directly or indirectly, the gross receipts, net income or value of the
      Trust Estate by reason of the creation or continued existence of the
      trust under the terms of the Trust Agreement pursuant to the laws of
      the State of Utah or the Owner Trustee's performance of its duties
      under the Trust Agreement within such State.

           (10) Neither a Utah court nor a federal court applying Utah law
      or federal law, if properly presented with the issue and after having
      properly considered such issue, would permit the Owner Participant to
      terminate the Trust Agreement, except in accordance with its terms.

           (11) Although there is no Utah case directly on point, under the
      laws of the State of Utah, so long as the Trust Agreement has not been
      terminated in accordance with its terms, creditors of any person that
      is an Owner Participant, holders of a lien against the assets of any
      such person that is an Owner Participant, such as trustees, receivers
      or liquidators (whether or not an insolvency proceeding has been
      commenced) (collectively the "Creditors") may acquire valid claims and
      liens, as to the Trust Estate, only against the rights of such Owner
      Participant under the Trust Agreement or in the Trust Estate, and do
      not have, and may not through the enforcement of such Creditors'
      rights acquire, any greater rights than such Owner Participant with
      respect to the Trust Agreement or the Trust Estate.

 The foregoing opinions are subject to the following assumptions, exception
 and qualifications:

      A.   The foregoing opinions are limited to the laws of the State of
      Utah and the federal laws of the United States of America governing
      the banking and trust powers of First Security and Title II of the
      United States Code entitled "Bankruptcy".  In addition, we express no
      opinion with respect to (i) federal securities laws, including the
      Securities Act of 1933, as amended, the Securities Exchange Act of
      1934, as amended, and the Trust Indenture Act of 1939, as amended;
      (ii) the Federal Aviation Act of 1958, as amended (except with respect
      to the opinion set forth in paragraph 1 above concerning the
      citizenship of First Security); or (iii) state securities or blue sky
      laws.  Insofar as the foregoing opinions relate to the legality,
      validity, binding effect and enforceability of the documents involved
      in these transactions, which by their terms are governed by the laws
      of a state other than Utah, we have assumed that such documents
      constitute legal, valid, binding and enforceable agreements under the
      laws of such state, as to which we express no opinion.

      B.   The foregoing opinions regarding enforceability of any document
      or instrument are subject (i) except as otherwise set forth in the
      opinions in paragraphs 10 and 11, to  applicable bankruptcy,
      insolvency, moratorium, reorganization, receivership and similar laws
      affecting the rights and remedies of creditors generally, and (ii)
      general principles of equity, regardless of whether such
      enforceability is considered in a proceeding in equity or at law.  We
      call to your attention that bankruptcy courts are courts in equity
      with wide discretion in applying the provisions of the Bankruptcy
      Code.

      C.   As to the documents involved in these transactions, we have
      assumed that each is a legal, valid and binding obligation of each
      party thereto, other than First Security or the Owner Trustee, and is
      enforceable against each such party in accordance with their
      respective terms.

      D.   The opinion in paragraph 1 above concerning the citizenship of
      First Security is based upon the facts contained in an affidavit of
      First Security, made by its authorized officer, which facts we have
      not independently verified.

      E.   We have assumed that all signatures, other than those of the
      Owner Trustee or First Security, on documents and instruments involved
      in these transactions are genuine, that all documents and instruments
      submitted to us as originals are authentic, and that all documents and
      instruments submitted to us conform with the originals, which facts we
      have not independently verified.

      F.   We do not purport to be experts in respect of, or express any
      opinion concerning laws, rules or regulations applicable to the
      particular nature of the equipment involved in these transactions.

      G.   We have made no investigation of, and express no opinion
      concerning, the nature of the title to any part of the equipment
      involved in these transactions or the priority of any mortgage or
      security interest.

      H.   We have assumed that the Participation Agreement and the
      transactions contemplated thereby are not within the prohibitions of
      Section 406 of the Employee Retirement Income Security Act of 1974.

      I.   In addition to any other limitation by operation of law upon the
      scope, meaning or purpose of this opinion, this opinion speaks only as
      of the date hereof. We have no obligation to advise the recipients of
      this opinion (or any third party) of changes of law or fact that may
      occur after the date hereof, even though the change may effect the
      legal analysis, a legal conclusion or any information contained
      herein.

      J.   The opinions expressed in this letter are solely for the use of
      the parties which it is addressed in matters directly related to the
      Participation Agreement and the transactions contemplated thereunder
      and these opinions may not be relied on by any other persons or for
      any other purpose without our prior written approval. The opinions
      expressed in this letter are limited to the matters set forth in this
      letter and no other opinions should be inferred beyond the matters
      expressly stated.

                          Very truly yours,

To the Persons Listed on
Schedule A Attached Hereto

               Re:  N___U__

Ladies and Gentlemen:

               We have acted as special counsel to __________________, a
____________________ (the "Owner Participant") in connection with the
transactions contemplated by the Participation Agreement N___U_ dated as of
______________, ____ (the "Participation Agreement"), among US Airways, a
Delaware corporation, as Lessee; the Owner Participant; First Security
Bank, National Association, a national banking association, not in its
individual capacity except as expressly provided therein, but solely as
Owner Trustee; State Street Bank and Trust Company of Connecticut, National
Association , a national banking association, not in its individual
capacity except as expressly stated therein, but solely as Pass Through
Trustee. Capitalized terms used in this opinion and not defined herein
shall have the, respective meanings assigned thereto in Annex A to the
Participation Agreement. Our opinion is being delivered, at the request of
the Owner Participant, pursuant to Section 4(a)(xiv) of the Participation
Agreement.

               In connection with the opinions contained herein, we have
examined executed counterparts of each of the Operative Documents. The
Operative Documents to which the Owner Participant is a party are herein
referred to as the "Owner Participant Documents".

               For purposes of the opinions expressed below, we have
examined the originals or conformed copies of such corporate records and
documents, certificates and statements of public officials and such other
documents and records, and such other matters of law, as we have deemed
appropriate as a basis for the opinions hereinafter expressed. We have made
no independent inquiry or investigation of any factual matters or
circumstances relevant to the opinions contained herein, but instead we
have relied upon representations in the Operative Documents and upon
certificates and statements of the parties thereto and of public officials.

               For the purposes of the opinions expressed below, we have
assumed (i) the authenticity of all documents submitted as originals; (ii)
the conformity to the originals of all documents submitted as certified or
photostatic copies and the authenticity of the originals; (iii) the legal
capacity of all natural persons who are parties to the Operative Documents;
(iv) the due authorization, execution and delivery of the Owner Participant
Documents by all parties; and (v) the legality, validity and binding effect
of the Owner Participant Documents as to, and the enforceability of the
same against, all parties (other than the Owner Participant).

               Based upon the foregoing and such other information as we
have deemed necessary for purposes hereof, and subject to the assumptions,
qualifications and reliances set forth herein, we are of the opinion that:

               1. Each of the Owner Participant Documents to which the
        Owner Participant is a party constitutes a legal, valid and binding
        obligation of the Owner Participant, enforceable against the Owner
        Participant in accordance with their respective terms.

               2. Neither the execution, delivery or performance by the
        Owner Participant of the Owner Participant Documents to which the
        Owner Participant is a party, the consummation by the Owner
        Participant of any of the transactions contemplated thereby, nor
        compliance by the Owner Participant with the provisions thereof (a)
        violates any New York or federal laws, rules or regulations or (b)
        requires the consent, permit, authorization or approval of, the
        giving of notice to, the registration or filing with, or the taking
        of any other action in respect of any governmental authority or
        agency of the United States or the State of New York (except for
        compliance with the requirements of the Federal Aviation Act, as to
        which we express no opinion).

               Our opinion as to the enforceability of any Owner
        Participant Document is qualified by and subject to:

               (i) limitations imposed by bankruptcy, insolvency,
        reorganization, moratorium or other similar laws affecting the
        enforcement of creditors' rights generally, and laws relating to
        fraudulent transfers or conveyances, preferences and equitable
        subordination;

               (ii) general principles of equity, including, without
        limitation, concepts of materiality, reasonableness, good faith and
        fair dealing (regardless of whether enforcement is sought in a
        proceeding in equity or at law);

               (iii) the unenforceability under certain circumstances of
        provisions purporting to release or exculpate any party from
        liability for its acts or omissions, or purporting to impose a duty
        upon any party to indemnify any other party when any claimed
        damages result from the gross negligence or willful misconduct of
        the party seeking such indemnity; and

               (iv) the unenforceability under certain circumstances of
        waivers, and provisions imposing liquidated damages, late payment
        charges or forfeitures, if such amounts are determined to be
        penalties in light of the actual damages incurred.

               Anything in this opinion to the contrary notwithstanding, we
express no opinion concerning (i) the enforceability of any indemnification
agreements or of any waivers of the benefits of any constitutional,
statutory or common law rights contained in any of the Operative Documents
to the extent such enforceability may be barred or limited by public policy
considerations; (ii) federal and state applicable laws relating to
environmental matters or the offering of securities; (iii) the Employee
Retirement Income Security Act of 1974, as amended; (iv) federal or state
laws, rules or regulations governing banking or trust powers; (v) the
ownership of, or legal or equitable title to any property; or (vi) the
priority of any security interest contemplated by the Operative Documents.

               We are members of the bar of the State of New York and,
accordingly, we do not purport to express any opinion on any laws other
than the laws of the State of New York and the federal laws of the United
States of America, in each case as such laws are in effect on the date
hereof With respect to the Owner Participant Documents which by their terms
are to be governed by and construed in accordance with laws other than the
laws of the state of New York, we have assumed for purposes hereof that
such laws are identical in all respects to the laws of the state of New
York.

               This opinion is furnished by us at your request for your
sole benefit and no one but an addressee (and any permitted transferee) is
entitled to rely on this opinion without our express written consent. This
opinion shall not be published or reproduced in any manner or distributed
or circulated to any person or entity without our express written consent.
Our opinion is limited to the matters stated herein, and no opinion is
implied or may be inferred beyond the matters expressly stated herein.


Very truly yours,

                        FORM OF FAA COUNSEL OPINION

                           ___________, 2000


  To the Addressees on the
  Schedule Attached Hereto

       RE:  AIRBUS INDUSTRIE MODEL A330___ AIRCRAFT WITH
            MANUFACTURER'S SERIAL NUMBER _____ AND UNITED STATES
            NATIONALITY AND REGISTRATION MARKS N____ (THE
            "AIRCRAFT")

  Ladies and Gentlemen:

       This letter confirms that we filed the following described
  instruments with the Federal Aviation Administration (the "FAA") today at
  the respective times noted below:

       (a)  AC Form 8050-2 Aircraft Bill of Sale dated _________ __, 2000
            (the "FAA Bill of Sale") by US Airways, Inc. (the "Lessee") to
            _______________, as Owner Trustee (the "Owner Trustee") under
            Trust Agreement (US Airways, Inc. 2000-1 Series N_____) dated
            as of ___________ __, 2000 (the "Trust Agreement") between
            _______________________ as Owner Participant and the Owner
            Trustee, covering the Aircraft was filed at __:__ _.M., C._.T.;

       (b)  AC Form 8050-1 Aircraft Registration Application by the Owner
            Trustee covering the Aircraft, to which were attached the
            Affidavits required by Section 47.7(c)(2)(ii) of Part 47 of the
            Federal Aviation Regulations, was filed at __:__ _.M., C._.T.;

       (c)  the Trust Agreement was filed at __:__ _.M., C._.T.;

       (d)  Trust Indenture and Security Agreement (US Airways, Inc.2000-1
            Series N_____) dated as of _______ __, 2000 (the "Indenture")
            between the Owner Trustee and ________________ as Indenture
            Trustee (the "Indenture Trustee"), to which was attached Trust
            Agreement and Indenture Supplement No. 1 (US Airways,
            Inc.2000-1 Series N_____) dated ___________ __, 2000 (the
            "Indenture Supplement") covering the Aircraft and the
            _______________ model ___________ aircraft engines with
            manufacturer's serial numbers ____________ and ______________
            (the "Engines"), was filed at __:__ _.M., C._.T.; and

       (e)  Lease Agreement dated as of ___________ __, 2000 (the "Lease")
            between the Owner Trustee as lessor and the Lessee, to which

            Supplement") covering the Aircraft and the Engines, the
            Indenture and the Indenture Supplement, was filed at __:__
            _.M., C._.T.

       Based upon our examination of the above described instruments and of
  such records of the FAA as we deemed necessary to render this opinion and
  as were made available to us by the FAA, it is our opinion that:

       (a)  the FAA Bill of Sale, the Indenture with the Indenture
            Supplement attached and the Lease with the Lease Supplement,
            the Indenture and the Indenture Supplement attached are in due
            form for recordation by and have been duly filed for
            recordation with the FAA pursuant to and in accordance with the
            provisions of Section 44107 of Title 49 of the United
            States Code;

       (b)  legal title to the Aircraft is vested in the Owner Trustee and
            all instruments necessary to cause the FAA in due course to
            issue to the Owner Trustee an AC Form 8050-3 Certificate of
            Aircraft Registration covering the Aircraft have been duly
            filed with the FAA pursuant to and in accordance with the
            provisions of Sections 44102 and 44103 of Title 49 of the
            United States Code;

       (c)  the Aircraft and the Engines are free and clear of Liens (as
            such term is defined in Annex A to the Indenture and the Lease)
            other than such as are created by the Indenture, as
            supplemented by the Indenture Supplement, and by the Lease, as
            supplemented by the Lease Supplement;

       (d)  the Indenture, as supplemented by the Indenture Supplement,
            creates a duly and validly perfected first priority security
            interest in favor of the Indenture Trustee in the Aircraft and
            the Engines and in all of the right, title and interest of the
            Owner Trustee in and to the Lease, as supplemented by the Lease
            Supplement (insofar as such security interest affects an
            interest covered by the recording system established by the FAA
            pursuant to Section 44107 of Title 49 of the United States
            Code);

       (e)  the rights of the Owner Trustee and the Lessee under the Lease,
            as supplemented by the Lease Supplement, with respect to the
            Aircraft and the Engines are perfected;

       (f)  the Indenture, as supplemented by the Indenture Supplement, is
            not required to be refiled with the FAA or filed or recorded in
            any other place within the United States in order to perfect or
            maintain the perfection of the security interest created
            thereby in the Aircraft and the Engines under the applicable
            laws of any jurisdiction within the United States;

       (g)  no other registration of the Aircraft and no filings or
            recordings (other than the filings and recordings with the FAA
            which have been effected) are necessary to perfect in any
            jurisdiction within the United States the Owner Trustee's title
            to the Aircraft or the security interest created by the
            Indenture, as supplemented by the Indenture Supplement, in the
            Aircraft and the Engines under the applicable laws of any
            jurisdiction within the United States; and

       (h)  no authorization, approval, consent, license or order of, or
            registration with, or giving of notice to, the FAA Aircraft
            Registry is required for the valid authorization, delivery or
            performance of the Lease, the Lease Supplement, the Trust
            Agreement, the Indenture and the Indenture Supplement except
            for such authorizations, approvals, consents, licenses, orders,
            registrations and notices as have been effected.

       No opinion is herein expressed as to: (i) laws other than the
  federal laws of the United States; (ii) the validity or enforceability
  under local law of the Indenture, as supplemented by the Indenture
  Supplement; (iii) the recognition of the perfection of the security
  interest created by the Indenture, as supplemented by the Indenture
  Supplement, as against third parties in any legal proceedings outside the
  United States; and (iv) the record status of the Aircraft prior to the
  commencement of its United States registration.  Since our examination
  was limited to records maintained by the FAA Aircraft Registry, our
  opinion does not cover liens which are perfected without the filing of
  notice thereof with the FAA, such as federal tax liens, liens arising
  under Section 1368(a) of Title 29 of the United States Code and
  possessory artisans' liens, and was subject to the accuracy of FAA
  personnel in the filing, indexing and recording of instruments filed with
  the FAA and in the search for encumbrance cross-reference index cards for
  the Engines.  This opinion is rendered in reliance upon the opinion of
  the Aeronautical Center Counsel dated ________ __, 2000 (a copy of which
  is attached hereto) and upon the past practice of the FAA which is
  consistent with said opinion.

                                Very truly yours,


                                ROBIN D. JENSON

            RE: US Airways, Inc./Leveraged Lease Financing of One
            Airbus [A320] [A330-300] Aircraft [N _____ US] -
            Indenture Trustee

Ladies and Gentlemen:

     We have acted as special counsel for State Street Bank and Trust
Company of Connecticut, National Association, in its individual capacity
("STATE STREET") and as Indenture Trustee (the "INDENTURE TRUSTEE") under
the Trust Indenture and Security Agreement [N ____ US] dated as of
[_______________, 2000] (the "INDENTURE") between First Security Bank,
National Association, not in its individual capacity, but solely as Owner
Trustee (the "OWNER TRUSTEE"), and State Street, as Indenture Trustee, in
connection with the execution and delivery of the Participation Agreement
[N ____ US] dated as of [_____________, 2000] (the "PARTICIPATION
AGREEMENT") by and among the Indenture Trustee, US Airways, Inc., as Lessee
(the "LESSEE"), [__________________], as Owner Participant, State Street,
as Pass Through Trustee (the "PASS THROUGH TRUSTEE"), State Street, as
Subordination Agent (the "SUBORDINATION AGENT") and the Owner Trustee and
the transactions contemplated thereby. Capitalized terms not otherwise
defined herein shall have the meanings specified in the Lease and Annex A
of the Participation Agreement. This opinion is being delivered at the
request of State Street and pursuant to Section 4(a)(xvi) of the
Participation Agreement.

     Our representation of State Street and the Indenture Trustee has been
as special counsel for the limited purposes stated above. As to all matters
of fact (including factual conclusions and characterizations and
descriptions of purpose, intention or other state of mind), we have relied,
with your permission, entirely upon (i) the representations and warranties
of the parties set forth in the Operative Documents and (ii) certificates
delivered to us by the management of State Street and have assumed, without
independent inquiry, the accuracy of those representations, warranties and
certificates.

     We have examined the Participation Agreement and the Indenture (the
"OPERATIVE DOCUMENTS"), the Certificate of the Comptroller of the Currency
relating to State Street and originals, or copies certified or otherwise
identified to our satisfaction, of such other records, documents,
certificates, or other instruments as we have deemed necessary or advisable
for the purposes of this opinion. For purposes of our opinion rendered in
paragraph 1 below, with respect to the authority of State Street to operate
as a national banking association and exercise trust powers, our opinion
relies upon and is limited by such Certificate of the Comptroller of the
Currency.

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

     When an opinion set forth below is given to the best of our knowledge,
or to our knowledge, or with reference to matters of which we are aware or
which are known to us, or with another similar qualification, the relevant
knowledge or awareness is limited to the actual knowledge or awareness of
the individual lawyer in the firm that signed this opinion, the individual
lawyers in the firm who have participated directly in the specific
transactions to which this opinion relates and the partner of the firm
responsible for State Street corporate trust matters, and without any
special or additional investigation undertaken for the purposes of this
opinion.

     Subject to the limitation set forth below, we have made such
examination of law as we have deemed necessary for the purposes of this
opinion. The opinions set forth below are limited solely to the internal
substantive laws of the State of Connecticut as applied by courts located
in Connecticut and the federal laws of the United States. No opinion is
given herein as to the choice of law or internal substantive rules of law
that any court or other tribunal may apply to the transactions contemplated
by the Operative Documents. No opinion is expressed herein as to the
application or effect of federal securities laws or as to the securities or
so-called "Blue Sky" laws of any state or other jurisdiction. In addition,
no opinion is expressed as to matters governed by any law, statute, rule or
regulation of the United States relating to the acquisition, ownership,
registration, use, operation, maintenance, repair, replacement or sale of
or the nature of the Aircraft.

     To the extent to which this opinion deals with matters governed by or
relating to the laws of the State of New York, or other jurisdiction other
than the State of Connecticut, by which the Operative Documents are stated
to be governed, we have assumed, with your permission that the Operative
Documents are governed by the internal substantive laws of the State of
Connecticut.

     Our opinion is further subject to the following exceptions,
qualifications and assumptions:

     1.   We have assumed without any independent investigation that (i)
          each party to the Operative Documents, other than State Street,
          in its individual capacity or as Indenture Trustee, as
          applicable, at all times relevant thereto, is validly existing
          and in good standing under the laws of the jurisdiction in which
          it is organized, and is qualified to do business and in good
          standing under the laws of each jurisdiction where such
          qualification is required generally or necessary in order for
          such party to enforce its rights under such Operative Documents,
          and (ii) each party to the Operative Documents, at all times
          relevant thereto, had and has the full power, authority and legal
          right under its certificate of incorporation, partnership
          agreement, bylaws, and other governing organizational documents,
          and the applicable corporate, partnership, or other enterprise
          legislation and other applicable laws, as the case may be (other
          than State Street and the Indenture Trustee with respect to the
          laws of the United States of America and the internal substantive
          laws of the State of the Connecticut, but only in each case to
          the limited extent the same may be applicable to State Street or
          the Indenture Trustee, and relevant to our opinions expressed
          below) to execute, and to perform its obligations under, the
          Operative Documents, and (iii) each party to the Operative
          Documents (other than State Street or the Indenture Trustee, as
          applicable) has duly executed and delivered each of such
          agreements and instruments to which it is a party and that (other
          than with respect to State Street and the Indenture Trustee, as
          applicable) the execution and delivery of such agreements and
          instruments and the transactions contemplated thereby have been
          duly authorized by proper corporate or other organizational
          proceedings as to such party.

     2.   We have assumed without any independent investigation (i) that
          each of the Operative Documents is a valid, binding and
          enforceable obligation of each party thereto other than State
          Street or the Indenture Trustee, as applicable, and (ii) that
          each of the Operative Documents is a valid, binding and
          enforceable obligation of State Street or the Indenture Trustee,
          as applicable, to the extent that laws other than those of the
          State of Connecticut are relevant thereto (other than the laws of
          the United States of America, but only to the limited extent the
          same may be applicable to State Street or the Indenture Trustee,
          as applicable, and relevant to our opinions expressed below).

     3.   The enforcement of any obligations of State Street or the
          Indenture Trustee, as applicable, under any of the Operative
          Documents may be limited by the receivership, conservatorship and
          supervisory powers of bank regulatory agencies generally, as well
          as by bankruptcy, insolvency, reorganization, moratorium,
          marshaling or other laws and rules of law affecting the
          enforcement generally of creditors' rights and remedies
          (including such as may deny giving effect to waivers of debtors'
          or guarantors' rights); and we express no opinion as to the
          status under any fraudulent conveyance laws or fraudulent
          transfer laws of any of the obligations of State Street or the
          Indenture Trustee, as applicable, under any of the Operative
          Documents.

     4.   We express no opinion as the availability of any specific or
          equitable relief of any kind.

     5.   The enforcement of any of your rights may in all cases be subject
          to an implied duty of good faith and fair dealing and to general
          principles of equity (regardless of whether such enforceability
          is considered in a proceeding at law or in equity) and, as to any
          of your rights to collateral security, will be subject to a duty
          to act in a commercially reasonable manner.

     6.   We express no opinion as to the enforceability of any particular
          provision of any of the Operative Documents relating to (i)
          waivers of rights to object to jurisdiction or venue, or consents
          to jurisdiction or venue, (ii) waivers of rights to (or methods
          of) service of process, or rights to trial by jury, or other
          rights or benefits bestowed by operation of law, (iii) waivers of
          any applicable defenses, setoffs, recoupments, or counterclaims,
          (iv) the grant of powers of attorney to any person or entity, (v)
          exculpation or exoneration clauses, indemnity clauses, and
          clauses relating to releases or waivers of unmatured claims or
          rights, (vi) the imposition or collection of interest on overdue
          interest or providing for a penalty rate of interest or late
          charges on overdue or defaulted obligations, or the payment of
          any premium, liquidated damages, or other amount which may be
          held by any court to be a "penalty" or a "forfeiture," or (vii)
          so-called "usury savings clauses" purporting to specify methods
          of (or otherwise assure) compliance with usury laws or other
          similar laws of any jurisdiction.

     7.   We express no opinion as to the effect of events occurring,
          circumstances arising, or changes of law becoming effective or
          occurring, after the date hereof on the matters addressed in this
          opinion letter, and we assume no responsibility to inform you of
          additional or changed facts, or changes in law, of which we may
          become aware.

     8.   No opinion is given herein as to the effect of usury laws (or
          other similar laws) of any jurisdiction with respect to the
          Operative Documents.

This opinion is rendered solely for the benefit of those institutions
listed on Schedule A hereto and their successors and assigns in connection
with the transactions contemplated by the Operative Documents and may not
be used or relied upon by any other person or for any other purpose.

Based upon the foregoing and subject to the limitations and qualifications
set forth herein, we are of the opinion that:

1. State Street is a national banking association, validly formed and
authorized to operate as a national banking association under the laws of
the United States of America and, in its individual capacity or as
Indenture Trustee, as the case may be, has the requisite corporate and
trust power and authority to execute, deliver and perform its obligations
under the Operative Documents and in its capacity as Indenture Trustee, to
authenticate the Equipment Notes issued on the date hereof.

2. State Street, in its individual capacity or as Indenture Trustee, as the
case may be, has duly authorized the Operative Documents by all necessary
corporate or trust action and has duly executed and delivered the Operative
Documents, and the Operative Documents constitute valid and binding
obligations of State Street, in its individual capacity or as Indenture
Trustee, as the case may be, enforceable against State Street, in its
individual capacity or as Indenture Trustee, as the case may be, in
accordance with their respective terms.

3. The Equipment Notes issued as of the date hereof have been duly
authenticated and delivered by State Street as Indenture Trustee pursuant
to the terms of the Indenture.

4. The authorization, execution, delivery and performance by State Street,
in its individual capacity or as Indenture Trustee, as the case may be, of
the Operative Documents and the consummation of the transactions therein
contemplated and compliance with the terms thereof do not and will not
result in the violation of the provisions of the charter documents or
by-laws of State Street and, to the best of our knowledge, do not conflict
with, or result in a breach of any terms or provisions of, or constitute a
default under, or result in the creation or the imposition of any lien,
charge or encumbrance upon any property or assets of State Street under any
indenture, mortgage or other agreement or instrument, in each case known to
us, to which State Street is a party or by which it is bound, or violates
any applicable Connecticut or federal law, rule or regulation governing
State Street's banking or trust powers, or, to the best of our knowledge,
of any judgment, order or decree, in each case known to us, applicable to
State Street of any court, regulatory body, administrative agency,
government or governmental body having jurisdiction over State Street.

5. No authorization, approval, consent, license or order of, giving of
notice to, registration with, or taking of any other action in respect of,
any federal or state governmental authority or agency pursuant to any
federal or Connecticut law governing the banking or trust powers of State
Street is required for the authorization, execution, delivery and
performance by State Street, in its individual capacity or as Indenture
Trustee, as the case may be, of the Operative Documents or the consummation
of any of the transactions by State Street, in its individual capacity or
as Indenture Trustee, as the case may be, contemplated thereby (except as
shall have been duly obtained, given or taken); and such authorization,
execution, delivery, performance, consummation and issuance do not conflict
with or result in a breach of the provisions of any such law.

6. There are no taxes, fees or other governmental charges payable under the
laws of the State of Connecticut or any political subdivision of such State
in connection with the execution and delivery by State Street, in its
individual capacity or as Indenture Trustee, as the case may be, of the
Operative Documents (except for taxes on any fees payable to State Street
in its individual capacity) which are imposed solely because State Street
has its principal place of business in Connecticut or performs its
administrative duties under the Operative Documents in Connecticut.

7. To our knowledge, but without having investigated any governmental
records or court dockets, and without having made any other independent
investigation, there are no proceedings pending or overtly threatened in
writing against or affecting State Street in any court or before any
governmental authority, agency, arbitration board or tribunal which, if
adversely determined, individually or in the aggregate, could reasonably be
expected to affect materially and adversely the trust related to the
Indenture or affect the right, power and authority of State Street, in its
individual capacity or as Indenture Trustee, as the case may be, to enter
into or perform its obligations under the Operative Documents.

                                            Very truly yours,




                                            BINGHAM DANA LLP

      RE:  US Airways, Inc./Leveraged Lease Financing of One
           Airbus [A320] [A330-300] Aircraft [N _________ US]
           -- Pass Through Trust

 Ladies and Gentlemen:

      We have acted as special counsel for State Street Bank and Trust
 Company of Connecticut, National Association, in its individual capacity
 ("STATE STREET") and as Pass Through Trustee (the "PASS THROUGH TRUSTEE")
 under the Pass Through Trust Agreement dated as of July 30, 1999, among US
 Airways Group, Inc., US Airways, Inc. and State Street, as supplemented by
 Trust Supplement No. 2000-1G and Trust Supplement No. 2000-1C, each dated
 as of [__________, 2000] and each among US Airways, Inc. and State Street
 (collectively, the "PASS THROUGH TRUSTS" and, individually, a "PASS THROUGH
 TRUST") in connection with the execution and delivery of the Participation
 Agreement [N   US] dated as of [             , 2000] (the "PARTICIPATION
 AGREEMENT") by and among State Street, as Indenture Trustee, US Airways,
 Inc., as Lessee (the "LESSEE"), [                      ], as Owner
 Participant, State Street, as Pass Through Trustee, State Street, as
 Subordination Agent (the "SUBORDINATION AGENT") and First Security Bank,
 National Association, as Owner Trustee and the transactions contemplated
 thereby.  Capitalized terms not otherwise defined herein shall have the
 meanings specified in the Lease and Annex A of the Participation Agreement.
 This opinion is being delivered  at the request of State Street and
 pursuant to Section 4(a)(xxiii) of the Participation Agreement.

      Our representation of State Street and the Pass Through Trustee has
 been as special counsel for the limited purposes stated above.  As to all
 matters of fact (including factual conclusions and characterizations and
 descriptions of purpose, intention or other state of mind), we have relied,
 with your permission, entirely upon (i) the representations and warranties
 of the parties set forth in the Operative Documents and (ii) certificates
 delivered to us by the management of State Street and have assumed, without
 independent inquiry, the accuracy of those representations, warranties and
 certificates.

      We have examined the Participation Agreement, the Liquidity Facility
 for each of the Class G and Class C Trusts, the Policy Provider Agreement,
 the Policy, the Intercreditor Agreement, the Note Purchase Agreement, the
 Escrow and Paying Agent Agreement for each of the Class G and Class C
 Trusts each dated as of ______________ __, 2000 and each among First
 Security Bank, National Association, as Escrow Agent, the underwriters
 named therein, State Street, as Pass Through Trustee and State Street, as
 Paying Agent, and each of the Pass Through Trusts (the "OPERATIVE
 DOCUMENTS"), the Certificate of the Comptroller of the Currency relating to
 State Street and originals, or copies certified or otherwise identified to
 our satisfaction, of such other records, documents, certificates, or other
 instruments as we have deemed necessary or advisable for the purposes of
 this opinion.  For purposes of our opinion rendered in paragraph 1 below,
 with respect to the authority of State Street to operate as a national
 banking association and exercise trust powers, our opinion relies upon and
 is limited by such Certificate of the Comptroller of the Currency.

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

      When an opinion set forth below is given to the best of our knowledge,
 or to our knowledge, or with reference to matters of which we are aware or
 which are known to us, or with another similar qualification, the relevant
 knowledge or awareness is limited to the actual knowledge or awareness of
 the individual lawyer in the firm that signed this opinion, the individual
 lawyers in the firm who have participated directly in the specific
 transactions to which this opinion relates and the partner of the firm
 responsible for State Street corporate trust matters, and without any
 special or additional investigation undertaken for the purposes of this
 opinion.

      Subject to the limitation set forth below, we have made such
 examination of law as we have deemed necessary for the purposes of this
 opinion.  The opinions set forth below are limited solely to the internal
 substantive laws of the State of Connecticut as applied by courts located
 in Connecticut and the federal laws of the United States.  No opinion is
 given herein as to the choice of law or internal substantive rules of law
 that any court or other tribunal may apply to the transactions contemplated
 by the Operative Documents.  No opinion is expressed herein as to the
 application or effect of federal securities laws or as to the securities or
 so-called "Blue Sky" laws of any state or other jurisdiction.  In addition,
 no opinion is expressed as to matters governed by any law, statute, rule or
 regulation of the United States relating to the acquisition, ownership,
 registration, use, operation, maintenance, repair, replacement or sale of
 or the nature of the Aircraft.

      To the extent to which this opinion deals with matters governed by or
 relating to the laws of the State of New York, or other jurisdiction other
 than the State of Connecticut, by which the Operative Documents are stated
 to be governed, we have assumed, with your permission that the Operative
 Documents are governed by the internal substantive laws of the State of
 Connecticut.

      Our opinion is further subject to the following exceptions,
 qualifications and assumptions:

            1. We have assumed without any independent investigation that
      (i) each party to the Operative Documents, other than State Street,
      in its individual capacity or as Pass Through Trustee, as applicable,
      at all times relevant thereto, is validly existing and in good
      standing under the laws of the jurisdiction in which it is organized,
      and is qualified to do business and in good standing under the laws
      of each jurisdiction where such qualification is required generally
      or necessary in order for such party to enforce its rights under such
      Operative Documents, and (ii) each party to the Operative Documents,
      at all times relevant thereto, had and has the full power, authority
      and legal right under its certificate of incorporation, partnership
      agreement, bylaws, and other governing organizational documents, and
      the applicable corporate, partnership, or other enterprise
      legislation and other applicable laws, as the case may be (other than
      State Street and the Pass Through Trustee with respect to the laws of
      the United States of America and the internal substantive laws of the
      State of Connecticut, but only in each case to the limited extent the
      same may be applicable to State Street or the Pass Through Trustee,
      and relevant to our opinions expressed below) to execute, and to
      perform its obligations under, the Operative Documents, and (iii)
      each party to the Operative Documents (other than State Street or the
      Pass Through Trustee, as applicable) has duly executed and delivered
      each of such agreements and instruments to which it is a party and
      that (other than with respect to State Street and the Pass Through
      Trustee, as applicable) the execution and delivery of such agreements
      and instruments and the transactions contemplated thereby have been
      duly authorized by proper corporate or other organizational
      proceedings as to such party.

            2. We have assumed without any independent investigation (i)
      that each of the Operative Documents is a valid, binding and
      enforceable obligation of each party thereto other than State Street
      or the Pass Through Trustee, as applicable, and (ii) that each of the
      Operative Documents is a valid, binding and enforceable obligation of
      State Street or the Pass Through Trustee, as applicable, to the
      extent that laws other than those of the State of Connecticut are
      relevant thereto (other than the laws of the United States of
      America, but only to the limited extent the same may be applicable to
      State Street or the Pass Through Trustee, as applicable, and relevant
      to our opinions expressed below).

            3. The enforcement of any obligations of State Street or the
      Pass Through Trustee, as applicable, under any of the Operative
      Documents may be limited by the receivership, conservatorship and
      supervisory powers of bank regulatory agencies generally, as well as
      by bankruptcy, insolvency, reorganization, moratorium, marshaling or
      other laws and rules of law affecting the enforcement generally of
      creditors' rights and remedies (including such as may deny giving
      effect to waivers of debtors' or guarantors' rights); and we express
      no opinion as to the status under any fraudulent conveyance laws or
      fraudulent transfer laws of any of the obligations of State Street or
      the Pass Through Trustee, as applicable, under any of the Operative
      Documents.

            4. We express no opinion as the availability of any specific or
      equitable relief of any kind.

            5. The enforcement of any of your rights may in all cases be
      subject to an implied duty of good faith and fair dealing and to
      general principles of equity (regardless of whether such
      enforceability is considered in a proceeding at law or in equity)
      and, as to any of your rights to collateral security, will be subject
      to a duty to act in a commercially reasonable manner.

            6. We express no opinion as to the enforceability of any
      particular provision of any of the Operative Documents relating to
      (i) waivers of rights to object to jurisdiction or venue, or consents
      to jurisdiction or venue, (ii) waivers of rights to (or methods of)
      service of process, or rights to trial by jury, or other rights or
      benefits bestowed by operation of law, (iii) waivers of any
      applicable defenses, setoffs, recoupments, or counterclaims, (iv) the
      grant of powers of attorney to any person or entity, (v) exculpation
      or exoneration clauses, indemnity clauses, and clauses relating to
      releases or waivers of unmatured claims or rights, (vi) the
      imposition or collection of interest on overdue interest or providing
      for a penalty rate of interest or late charges on overdue or
      defaulted obligations, or the payment of any premium, liquidated
      damages, or other amount which may be held by any court to be a
      "penalty" or a "forfeiture," or (vii) so-called "usury savings
      clauses" purporting to specify methods of (or otherwise assure)
      compliance with usury laws or other similar laws of any jurisdiction.

            7. We express no opinion as to the effect of events occurring,
      circumstances arising, or changes of law becoming effective or
      occurring, after the date hereof on the matters addressed in this
      opinion letter, and we assume no responsibility to inform you of
      additional or changed facts, or changes in law, of which we may
      become aware.

            8. No opinion is given herein as to the effect of usury laws
      (or other similar laws) of any jurisdiction with respect to the
      Operative Documents.

      In rendering the opinion set forth below in paragraph 6 as to certain
 Connecticut tax matters, we have assumed that, for federal income tax
 purposes, the trust created by the Trust Agreement will not be taxable as a
 corporation, but, rather, will be classified as a grantor trust under
 subpart E, Part I of Subchapter J of Chapter 1 of Subtitle A of the
 Internal Revenue Code of 1986, as amended or as a partnership.

      This opinion is rendered solely for the benefit of those institutions
 listed on Schedule A hereto and their successors and assigns in connection
 with the transactions contemplated by the Operative Documents and may not
 be used or relied upon by any other person or for any other purpose.

      Based upon the foregoing and subject to the limitations and
 qualifications set forth herein, we are of the opinion that:

      1.   State Street is a national banking association, validly formed
 and authorized to operate as a national banking association under the laws
 of the United States of America and, in its individual capacity or as Pass
 Through Trustee, as the case may be, has or had, as the case may be, the
 requisite corporate and trust power and authority to execute, deliver and
 perform its obligations under the Operative Documents and in its capacity
 as Pass Through Trustee, to issue and execute the Pass Through Certificates
 delivered on the Pass Through Trust Closing Date.

      2.   State Street, in its individual capacity or as Pass Through
 Trustee, as the case may be, has duly authorized by all necessary corporate
 or trust action the Operative Documents and has duly executed and delivered
 the Operative Documents, and the Operative Documents constitute valid and
 binding obligations of State Street, in its individual capacity or as Pass
 Through Trustee, as the case may be, enforceable against State Street, in
 its individual capacity or as Pass Through Trustee, as the case may be, in
 accordance with their respective terms.

      3.   The Pass Through Certificates issued and dated on the Pass
 Through Trust Closing Date have been duly issued, authenticated and
 delivered by State Street as Pass Through Trustee pursuant to the terms of
 the Operative Documents and are enforceable against the Pass Through
 Trustee and are entitled to the benefits of the applicable Pass Through
 Trusts.

      4.   The authorization, execution, delivery and performance by State
 Street, in its individual capacity or as Pass Through Trustee, as the case
 may be, of the Operative Documents and the consummation of the transactions
 therein contemplated and compliance with the terms thereof do not and will
 not result in the violation of the provisions of the charter documents or
 by-laws of State Street and, to the best of our knowledge, do not conflict
 with, or result in a breach of any terms or provisions of, or constitute a
 default under, or result in the creation or the imposition of any lien,
 charge or encumbrance upon any property or assets of State Street under any
 indenture, mortgage or other agreement or instrument, in each case known to
 us, to which State Street is a party or by which it is bound, or violates
 any applicable Connecticut or federal law, rule or regulation governing
 State Street's banking or trust powers, or, to the best of our knowledge,
 of any judgment, order or decree, in each case known to us, applicable to
 State Street of any court, regulatory body, administrative agency,
 government or governmental body having jurisdiction over State Street.

      5.   No authorization, approval, consent, license or order of, giving
 of notice to, registration with, or taking of any other action in respect
 of, any federal or state governmental authority or agency pursuant to any
 federal or Connecticut law governing the banking or trust powers of State
 Street is required for the authorization, execution, delivery and
 performance by State Street, in its individual capacity or as Pass Through
 Trustee, as the case may be, of the Operative Documents or the consummation
 of any of the transactions by State Street, in its individual capacity or
 as Pass Through Trustee, as the case may be, contemplated thereby (except
 as shall have been duly obtained, given or taken); and such authorization,
 execution, delivery, performance, consummation and issuance do not conflict
 with or result in a breach of the provisions of any such law.

      6.   There are no taxes, fees or other governmental charges payable
 under the laws of the State of Connecticut or any political subdivision of
 such State in connection with the execution and delivery by State Street,
 in its individual capacity or as Pass Through Trustee, as the case may be,
 of the Operative Documents (except for taxes on any fees payable to State
 Street in its individual capacity) or in connection with the issuance,
 execution and delivery of the Pass Through Certificates by State Street, as
 Pass Through Trustee, pursuant to the Pass Through Trusts which are imposed
 solely because State Street has its principal place of business in
 Connecticut or performs its administrative duties under the Operative
 Documents in Connecticut.  Neither State Street, in its individual capacity
 or as the Pass Through Trustee, as the case may be, the Indenture Trustee,
 the Owner Participant, the Owner Trustee, nor the trust created by the
 Trust Agreement will, as a result of the transactions contemplated thereby,
 be subject to any Taxes under the laws of the State of Connecticut or any
 political subdivision thereof (except for Taxes on any fees payable to
 State Street in its individual capacity) which are imposed because State
 Street has its principal place of business in Connecticut or performs its
 administrative duties under the Operative  Documents in Connecticut, and
 there are no Taxes under the laws of the State of Connecticut or any
 political subdivision thereof (except for Taxes on any fees payable to
 State Street in its individual capacity) upon or with respect to the
 Aircraft or any Engine or any part of any interest therein, or the
 purchase, ownership, delivery, lease, sublease, possession, presence, use,
 operation, condition, storage, maintenance, modification, alteration,
 repair, sale, return, transfer or other disposition of the Aircraft or any
 Engine which are imposed because State Street has its principal place of
 business in Connecticut or performs its administrative duties under the
 Operative Documents in Connecticut.

      7.   To our knowledge, but without having investigated any
 governmental records or court dockets, and without having made any other
 independent investigation, there are no proceedings pending or overtly
 threatened in writing against or affecting State Street in any court or
 before any governmental authority, agency, arbitration board or tribunal
 which, if adversely determined, individually or in the aggregate, could
 reasonably be expected to affect materially and adversely the trust related
 to the Indenture or affect the right, power and authority of State Street,
 in its individual capacity or as Pass Through Trustee, as the case may be,
 to enter into or perform its obligations under the Operative Documents.


                                        Very truly yours,


                                        BINGHAM DANA LLP

           Subordination Agent

 Ladies and Gentlemen:

      We have acted as special counsel for State Street Bank and Trust
 Company of Connecticut, National Association, in its individual capacity
 ("STATE STREET") and as Subordination Agent (the "SUBORDINATION AGENT")
 under the Intercreditor Agreement dated as of [________________] (the
 "INTERCREDITOR AGREEMENT") among State Street Bank , in its capacity as
 Pass Through Trustee under the US Airways Pass Through Trust 1999-1A, US
 Airways Pass Through Trust 1999-1B and US Airways Pass Through Trust 1999-
 C, [_______________], as Class A Liquidity Provider, Class B Liquidity
 Provider and Class C Liquidity Provider, and State Street, as Subordination
 Agent in connection with the execution and delivery of the Participation
 Agreement [N ____ US] dated as of [________________] (the "PARTICIPATION
 AGREEMENT") by and among State Street, as Indenture Trustee, US Airways,
 Inc., as Lessee (the "LESSEE"), [__________________], as Owner Participant,
 State Street, as Pass Through Trustee (the "PASS THROUGH TRUSTEE"), State
 Street, as Subordination Agent and First Security Bank, National
 Association, as Owner Trustee and the transactions contemplated thereby.
 Capitalized terms not otherwise defined herein shall have the meanings
 specified in the Lease and Annex A of the Participation Agreement.  This
 opinion is being delivered pursuant to Section 4(a)(____) of the
 Participation Agreement.

      Our representation of State Street and the Subordination Agent has
 been as special counsel for the limited purposes stated above.  As to all
 matters of fact (including factual conclusions and characterizations and
 descriptions of purpose, intention or other state of mind), we have relied,
 with your permission, entirely upon (i) the representations and warranties
 of the parties set forth in the Operative Documents and (ii) certificates
 delivered to us by the management of State Street and have assumed, without
 independent inquiry, the accuracy of those representations, warranties and
 certificates.

      We have examined the Participation Agreement, the Note Purchase
 Agreement and the Intercreditor Agreement (the "OPERATIVE DOCUMENTS"), the
 Certificate of the Comptroller of the Currency relating to State Street and
 originals, or copies certified or otherwise identified to our satisfaction,
 of such other records, documents, certificates, or other instruments as we
 have deemed necessary or advisable for the purposes of this opinion.  For
 purposes of our opinion rendered in paragraph 1 below, with respect to the
 authority of State Street to operate as a national banking association and
 exercise trust powers, our opinion relies upon and is limited by such
 Certificate of the Comptroller of the Currency.

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

      When an opinion set forth below is given to the best of our knowledge,
 or to our knowledge, or with reference to matters of which we are aware or
 which are known to us, or with another similar qualification, the relevant
 knowledge or awareness is limited to the actual knowledge or awareness of
 the individual lawyer in the firm that signed this opinion, the individual
 lawyers in the firm who have participated directly in the specific
 transactions to which this opinion relates and the partner of the firm
 responsible for State Street corporate trust matters, and without any
 special or additional investigation undertaken for the purposes of this
 opinion.

      Subject to the limitation set forth below, we have made such
 examination of law as we have deemed necessary for the purposes of this
 opinion.  The opinions set forth below are limited solely to the internal
 substantive laws of the State of Connecticut as applied by courts located
 in Connecticut and the federal laws of the United States.  No opinion is
 given herein as to the choice of law or internal substantive rules of law
 that any court or other tribunal may apply to the transactions contemplated
 by the Operative Documents.  No opinion is expressed herein as to the
 application or effect of federal securities laws or as to the securities or
 so-called "Blue Sky" laws of any state or other jurisdiction.  In addition,
 no opinion is expressed as to matters governed by any law, statute, rule or
 regulation of the United States relating to the acquisition, ownership,
 registration, use, operation, maintenance, repair, replacement or sale of
 or the nature of the Aircraft.

      To the extent to which this opinion deals with matters governed by or
 relating to the laws of the State of New York, or other jurisdiction other
 than the State of Connecticut, by which the Operative Documents are stated
 to be governed, we have assumed, with your permission that the Operative
 Documents are governed by the internal substantive laws of the State of
 Connecticut.

      Our opinion is further subject to the following exceptions,
 qualifications and assumptions:

            1. We have assumed without any independent investigation that
      (i) each party to the Operative Documents, other than State Street,
      in its individual capacity or as Subordination Agent, as applicable,
      at all times relevant thereto, is validly existing and in good
      standing under the laws of the jurisdiction in which it is organized,
      and is qualified to do business and in good standing under the laws
      of each jurisdiction where such qualification is required generally
      or necessary in order for such party to enforce its rights under such
      Operative Documents, and (ii) each party to the Operative Documents,
      at all times relevant thereto, had and has the full power, authority
      and legal right under its certificate of incorporation, partnership
      agreement, bylaws, and other governing organizational documents, and
      the applicable corporate, partnership, or other enterprise
      legislation and other applicable laws, as the case may be (other than
      State Street and the Subordination Agent with respect to the laws of
      the United States of America and the internal substantive laws of the
      State of Connecticut, but only in each case to the limited extent the
      same may be applicable to State Street or the Subordination Agent,
      and relevant to our opinions expressed below) to execute, and to
      perform its obligations under, the Operative Documents, and (iii)
      each party to the Operative Documents (other than State Street or the
      Subordination Agent, as applicable) has duly executed and delivered
      each of such agreements and instruments to which it is a party and
      that (other than with respect to State Street and the Subordination
      Agent, as applicable) the execution and delivery of such agreements
      and instruments and the transactions contemplated thereby have been
      duly authorized by proper corporate or other organizational
      proceedings as to such party.

            2. We have assumed without any independent investigation (i)
      that each of the Operative Documents is a valid, binding and
      enforceable obligation of each party thereto other than State Street
      or the Subordination Agent, as applicable, and (ii) that each of the
      Operative Documents is a valid, binding and enforceable obligation of
      State Street or the Subordination Agent, as applicable, to the extent
      that laws other than those of the State of Connecticut are relevant
      thereto (other than the laws of the United States of America, but
      only to the limited extent the same may be applicable to State Street
      or the Subordination Agent, as applicable, and relevant to our
      opinions expressed below).

            3. The enforcement of any obligations of State Street or the
      Subordination Agent, as applicable, under any of the Operative
      Documents may be limited by the receivership, conservatorship and
      supervisory powers of bank regulatory agencies generally, as well as
      by bankruptcy, insolvency, reorganization, moratorium, marshaling or
      other laws and rules of law affecting the enforcement generally of
      creditors' rights and remedies (including such as may deny giving
      effect to waivers of debtors' or guarantors' rights); and we express
      no opinion as to the status under any fraudulent conveyance laws or
      fraudulent transfer laws of any of the obligations of State Street or
      the Subordination Agent, as applicable, under any of the Operative
      Documents.

            4. We express no opinion as the availability of any specific or
      equitable relief of any kind.

            5. The enforcement of any of your rights may in all cases be
      subject to an implied duty of good faith and fair dealing and to
      general principles of equity (regardless of whether such
      enforceability is considered in a proceeding at law or in equity)
      and, as to any of your rights to collateral security, will be subject
      to a duty to act in a commercially reasonable manner.

            6. We express no opinion as to the enforceability of any
      particular provision of any of the Operative Documents relating to
      (i) waivers of rights to object to jurisdiction or venue, or consents
      to jurisdiction or venue, (ii) waivers of rights to (or methods of)
      service of process, or rights to trial by jury, or other rights or
      benefits bestowed by operation of law, (iii) waivers of any
      applicable defenses, setoffs, recoupments, or counterclaims, (iv) the
      grant of powers of attorney to any person or entity, (v) exculpation
      or exoneration clauses, indemnity clauses, and clauses relating to
      releases or waivers of unmatured claims or rights, (vi) the
      imposition or collection of interest on overdue interest or providing
      for a penalty rate of interest or late charges on overdue or
      defaulted obligations, or the payment of any premium, liquidated
      damages, or other amount which may be held by any court to be a
      "penalty" or a "forfeiture," or (vii) so-called "usury savings
      clauses" purporting to specify methods of (or otherwise assure)
      compliance with usury laws or other similar laws of any jurisdiction.

            7. We express no opinion as to the effect of events occurring,
      circumstances arising, or changes of law becoming effective or
      occurring, after the date hereof on the matters addressed in this
      opinion letter, and we assume no responsibility to inform you of
      additional or changed facts, or changes in law, of which we may
      become aware.

            8. No opinion is given herein as to the effect of usury laws
      (or other similar laws) of any jurisdiction with respect to the
      Operative Documents.

      This opinion is rendered solely for the benefit of those institutions
 listed on Schedule A hereto and their successors and assigns in connection
 with the transactions contemplated by the Operative Documents and may not
 be used or relied upon by any other person or for any other purpose.

      1.   State Street is a national banking association, validly formed
 and authorized to operate as a national banking association under the laws
 of the United States of America and, in its individual capacity or as
 Subordination Agent, as the case may be, has the requisite corporate and
 trust power and authority to execute, deliver and perform its obligations
 under the Operative Documents.

      2.   State Street, in its individual capacity or as Subordination
 Agent, as the case may be, has duly authorized the Operative Documents by
 all necessary corporate or trust action and has duly executed and delivered
 the Operative Documents, and the Operative Documents constitute valid and
 binding obligations of State Street, in its individual capacity or as
 Subordination Agent, as the case may be, enforceable against State Street,
 in its individual capacity or as Subordination Agent, as the case may be,
 in accordance with their respective terms.

      3.   The authorization, execution, delivery and performance by State
 Street, in its individual capacity or as Subordination Agent, as the case
 may be, of the Operative Documents and the consummation of the transactions
 therein contemplated and compliance with the terms thereof do not and will
 not result in the violation of the provisions of the charter documents or
 by-laws of State Street and, to the best of our knowledge, do not conflict
 with, or result in a breach of any terms or provisions of, or constitute a
 default under, or result in the creation or the imposition of any lien,
 charge or encumbrance upon any property or assets of State Street under any
 indenture, mortgage or other agreement or instrument, in each case known to
 us, to which State Street is a party or by which it is bound, or violates
 any applicable Connecticut or federal law, rule or regulation governing
 State Street's banking or trust powers, or, to the best of our knowledge,
 of any judgment, order or decree, in each case known to us, applicable to
 State Street of any court, regulatory body, administrative agency,
 government or governmental body having jurisdiction over State Street.

      4.   No authorization, approval, consent, license or order of, giving
 of notice to, registration with, or taking of any other action in respect
 of, any federal or state governmental authority or agency pursuant to any
 federal or Connecticut law governing the banking or trust powers of State
 Street is required for the authorization, execution, delivery and
 performance by State Street, in its individual capacity or as Subordination
 Agent, as the case may be, of the Operative Documents or the consummation
 of any of the transactions by State Street, in its individual capacity or
 as Subordination Agent, as the case may be, contemplated thereby (except as
 shall have been duly obtained, given or taken); and such authorization,
 execution, delivery, performance, consummation and issuance do not conflict
 with or result in a breach of the provisions of any such law.

      5.   There are no taxes, fees or other governmental charges payable
 under the laws of the State of Connecticut or any political subdivision of
 such State in connection with the execution and delivery by State Street,
 in its individual capacity or as Subordination Agent, as the case may be,
 of the Operative Documents (except for taxes on any fees payable to State
 Street in its individual capacity) which are imposed solely because State
 Street has its principal place of business in Connecticut or performs its
 administrative duties under the Operative Documents in Connecticut.

      6.   To our knowledge, but without having investigated any
 governmental records or court dockets, and without having made any other
 independent investigation, there are no proceedings pending or overtly
 threatened in writing against or affecting State Street in any court or
 before any governmental authority, agency, arbitration board or tribunal
 which, if adversely determined, individually or in the aggregate, could
 reasonably be expected to affect materially and adversely the trust related
 to the Indenture or affect the right, power and authority of State Street,
 in its individual capacity or as Subordination Agent, as the case may be,
 to enter into or perform its obligations under the Operative Documents.

      7.   Assuming that the Subordination Agent holds each of the Equipment
 Notes delivered to and registered in its name pursuant to and as required
 by the Intercreditor Agreement, it holds such Equipment Notes in trust as
 trustee for the related Pass Through Trustee in the exercise of the
 fiduciary powers conferred upon State Street by Connecticut law.

                               Very truly yours,


                               BINGHAM DANA LLP

                              LEASE AGREEMENT

                        (US Airways, Inc. Trust No. N___U_)

               This LEASE AGREEMENT (US Airways, Inc. Trust No. N___U_),
dated as of __________ __,____, between FIRST SECURITY BANK, NATIONAL
ASSOCIATION, not in its individual capacity, except as expressly provided
herein, but solely as Owner Trustee under the Trust Agreement (as defined
in Annex A hereto) (in such capacity, "Lessor"), and US AIRWAYS, INC., a
corporation organized and existing pursuant to the laws of the State of
Delaware ("Lessee");

                               W I T N E S S E T H:
                               -------------------

               SECTION 1. DEFINITIONS. Capitalized terms used but not
defined herein shall have the respective meanings set forth or incorporated
by reference, and shall be construed and interpreted in the manner
described, in Annex A.

               SECTION 2. ACCEPTANCE AND LEASE. Lessor hereby agrees
(subject to satisfaction of the conditions set forth in Section 4(a) of the
Participation Agreement) to accept the transfer of title from and
simultaneously to lease to Lessee hereunder, and Lessee hereby agrees
(subject to satisfaction of the conditions set forth in Section 4(b) of the
Participation Agreement) to lease from Lessor hereunder, the Aircraft as
evidenced by the execution by Lessor and Lessee of a Lease Supplement
leasing the Aircraft hereunder. Lessee hereby agrees that such acceptance
of the Aircraft by Lessor shall, without further act, irrevocably
constitute acceptance by Lessee of such Aircraft for all purposes of this
Lease.

               SECTION 3.   TERM AND RENT.
                            -------------

               (a)    Basic Term.  The Basic Term shall commence on the
Delivery Date and end on the Basic Term Expiration Date.

               (b) Basic Rent. Lessee shall pay Basic Rent with respect to
each Lease Period during the Basic Term on each Lease Period Date during
the Basic Term, in consecutive installments in the amounts as provided in
the next sentence, each such installment to cover the Lease Period
specified in Exhibit B. Each such installment of Basic Rent shall be equal
to Lessor's Cost multiplied by the percentage for the Delivery Date or
applicable Lease Period Date, as the case may be, specified in Exhibit B
hereto.

               (c)    Adjustments to Basic Rent.

                      (i) In the event of a refinancing as contemplated by
        Section 16 of the Participation Agreement, then the Basic Rent
        percentages set forth in Exhibit B, the Termination Value
        percentages set forth in Exhibit C and the EBO Amount set forth on
        Exhibit D shall be recalculated (upwards or downwards) by the Owner
        Participant as contemplated by such Section to (1) maintain the
        Owner Participant's Net Economic Return and (2) to the extent
        possible consistent with clause (1) hereof, minimize the Net
        Present Value of Rents to Lessee;

                      (ii) In the event that Lessee elects to satisfy any
        indemnity obligation under the Tax Indemnity Agreement, then the
        Basic Rent percentages set forth in Exhibit B, the Termination
        Value percentages set forth in Exhibit C and the EBO Amount set
        forth on Exhibit D shall be recalculated (upwards or downwards) by
        the Owner Participant, using the same methods and assumptions
        (except to the extent such assumptions shall be varied to take into
        account the Loss (as defined in the Tax Indemnity Agreement) that
        is the subject of such indemnification and any prior or
        contemporaneous Loss) used to calculate the Basic Rent percentages,
        the Termination Value percentages and the EBO Amount on the
        Delivery Date, in order to (1) maintain the Owner Participant's Net
        Economic Return and (2) to the extent possible consistent with
        clause (1) hereof, minimize the Net Present Value of Rents to
        Lessee.

                      (iii) Whenever Basic Rent is recalculated pursuant to
        this Section 3(c), the Owner Participant shall redetermine the
        Termination Value percentages set forth in Exhibit C and the EBO
        Amount set forth in Exhibit D in a manner consistent with such
        recalculation.

                      (iv) Any recalculation of Basic Rent and Termination
        Value percentages pursuant to this Section 3(c) shall be determined
        by the Owner Participant and shall be subject to the verification
        procedures set forth in Exhibit E hereto. Such recalculated Basic
        Rent and Termination Value percentages shall be set forth in a
        Lease Supplement or an amendment to this Lease.

                      (v) Anything contained in the Participation Agreement
        or this Lease to the contrary notwithstanding (I) each
        installment of Basic Rent payable hereunder, whether or not
        adjusted in accordance with this Section 3(c), shall be, under
        any circumstances and in any event, in an amount at least
        sufficient to pay in full, on the date on which such installment
        of Basic Rent is due, any payments then scheduled to be made on
        account of the principal of and interest on the Equipment Notes
        and (II) the amount of Termination Value payable on any
        Termination Date, Loss Payment Date or, in the case of payments
        under Sections 15 and 20, Lease Period Date, whether or not
        adjusted in accordance with this Section 3(c), together with all
        other amounts payable hereunder by Lessee on such date and the
        amount of the premium, if any, payable by Lessor on the Equipment
        Notes, shall be, under any circumstances and in any event, in an
        amount at least sufficient for Lessor to pay in full, on such
        Termination Date, Loss Payment Date or Lease Period Date, the
        outstanding principal of, premium, if any, and interest on the
        Equipment Notes. It is agreed that no installment of Basic Rent,
        payment of Termination Value or EBO Amount shall be increased or
        adjusted by reason of (i) any attachment or diversion of Rent on
        account of (A) Lessor Liens or (B) any Loan Participant Lien or
        other Lien on or against the Trust Estate, any part thereof or
        the Operative Documents arising as a result of claims against the
        Indenture Trustee not related to the transactions contemplated by
        the Operative Documents, (ii) any modification of the payment
        terms of the Equipment Notes made without the prior written
        consent of Lessee or (iii) the acceleration of any Equipment Note
        or Equipment Notes due to the occurrence of an Indenture Event of
        Default which does not constitute a Lease Event of Default.

                      (vi) All adjustments to Basic Rent under this Section
        3(c) shall be subject to verification pursuant to Exhibit E.

               (d) Supplemental Rent. Lessee shall pay (or cause to be
paid) promptly to Lessor, or to whomsoever shall be entitled thereto, any
and all Supplemental Rent constituting Termination Value and Make-Whole
Amount as the same shall become due and owing and all other amounts of
Supplemental Rent within five Business Days (5) days after demand or within
such other relevant period as may be provided in any Operative Document,
and in the event of any failure on the part of Lessee to pay any
Supplemental Rent when due, Lessor shall have all rights, powers and
remedies provided for herein or in any other Operative Document or by law
or equity or otherwise in the case of nonpayment of Basic Rent. Lessee
shall pay as Supplemental Rent the Make-Whole Amount, if any, due pursuant
to Section 2.10(b) or Section 2.11 of the Trust Indenture in connection
with a prepayment of the Equipment Notes upon redemption of such Equipment
Notes in accordance with Section 2.10(b) or Section 2.11 of the Trust
Indenture. Lessee also will pay to Lessor, or to whomsoever shall be
entitled thereto, on demand, as Supplemental Rent, to the extent permitted
by applicable law, interest at the Past Due Rate on any part of any
installment of Basic Rent not paid when due for any period for which the
same shall be overdue and on any payment of Supplemental Rent not paid when
due for the period until the same shall be paid.

               (e) Payments in General. All payments of Rent shall be made
directly by Lessee (whether or not any Sublease shall be in effect) by wire
transfer of immediately available funds prior to 11:00 a.m., New York time,

               (f)    Business Day Convention.  Notwithstanding anything to
the contrary contained herein, if any date on which a payment of Rent
becomes due and payable is not a Business Day, then such payment shall not
be made on such scheduled date but shall be made on the next succeeding
Business Day with the same force and effect as if made on such scheduled
date and (provided such payment is made on such next succeeding Business
Day) no interest shall accrue on the amount of such payment from and after
such scheduled date.

               SECTION 4.   DISCLAIMER; LESSOR'S REPRESENTATIONS, WARRANTIES
AND AGREEMENTS.

               (a) Disclaimer. LESSOR LEASES AND LESSEE TAKES THE AIRCRAFT

TRADEMARK OR COPYRIGHT, AS TO THE ABSENCE OF OBLIGATIONS BASED ON STRICT
LIABILITY IN TORT, OR ANY OTHER REPRESENTATION OR WARRANTY WHATSOEVER,
EXPRESS OR IMPLIED, WITH RESPECT TO THE AIRCRAFT OR ANY PART THEREOF.

               (b) Representations, Warranties and Covenants of First
Security Bank. First Security Bank, National Association, in its individual
capacity, (i) represents and warrants that on the Delivery Date, Lessor
shall have received whatever title to the Aircraft was conveyed to it by
Lessee, (ii) represents and warrants that on the Delivery Date the Aircraft
shall be free of Lessor Liens attributable to it, (iii) covenants that
neither it nor any Person claiming by, through or under it will, through
its own actions or inactions, interfere in Lessee's or any Sublessee's
continued possession, use, operation and quiet enjoyment of the Aircraft
during the Term unless an Event of Default has occurred and is continuing
and this Lease has been duly declared in default, and this Lease shall not
be terminated except as expressly provided herein, (iv) covenants that it
will not directly or indirectly create, incur, assume or suffer to exist
any Lessor Lien attributable to it on or with respect to the Airframe or

that if at any time it shall cease to be a Citizen of the United States
without making use of a voting trust, voting powers agreement or similar
arrangement it will promptly resign as Owner Trustee (if and so long as
such citizenship is necessary under the Transportation Code as in effect at
such time or, if it is not necessary, if and so long as the Owner Trustee's
citizenship would have any material adverse effect on the Loan
Participants, the Owner Participant or Lessee), effective upon the
appointment of a successor Owner Trustee in accordance with Section 9.01 of
the Trust Agreement.

               (c) Lessor's Covenants. Lessor (i) covenants that neither it
nor any Person claiming by, through or under it will, through its own
actions or inactions, interfere in Lessee's or any Sublessee's continued
possession, use, operation and quiet enjoyment of the Aircraft during the
Term unless an Event of Default has occurred and is continuing and this
Lease has been duly declared in default, and this Lease shall not be
terminated except as expressly provided herein and (ii) covenants that it
will not directly or indirectly create, incur, assume or suffer to exist
any Lessor Lien attributable to it on or with respect to the Airframe or
any Engine.

               (d) Manufacturer's Warranties. None of the provisions of
this Lease shall be deemed to amend, modify or otherwise affect the
representations, warranties or other obligations (express or implied) of
the Seller, the Manufacturer, any subcontractor or supplier of the
Manufacturer with respect to the Airframe, the Engines or any Parts, or to
release the Seller, the Manufacturer, or any such subcontractor or
supplier, from any such representation, warranty or obligation. Unless an
Event of Default shall have occurred and be continuing under Section 14 and
this Lease shall have been declared in default, Lessor agrees to make
available to Lessee such rights as Lessor may have under any warranty with
respect to the Aircraft made by the Seller, the Manufacturer or any
affiliate thereof or any of its subcontractors or suppliers and any other
claims against the Seller, the Manufacturer or any affiliate thereof, or
any such subcontractor or supplier with respect to the Aircraft, all
pursuant to and in accordance with the terms of the Purchase Agreement
Assignment.

               SECTION 5.   RETURN OF THE AIRCRAFT.

               (a)    Condition Upon Return.  Lessee shall comply with each of
the provisions of Exhibit G, which provisions are hereby incorporated by
this reference as if set forth in full herein.

               (b) Parking and Related Matters. Unless Lessee has elected
to purchase the Aircraft in accordance with the terms hereof, if Lessor
gives written notice to Lessee not less than sixty (60) days nor more than
one hundred eighty (180) days prior to the end of the Term requesting
storage of the Aircraft upon its return hereunder, Lessee will provide
Lessor, or cause Lessor to be provided, with outdoor parking facilities for
the Aircraft for a period up to thirty (30) days, commencing on the date of
such return, at such storage facility in the forty eight (48) contiguous
states of the United States as Lessee may select; provided that such
location shall be a location generally used for the parking of commercial
aircraft by aircraft owners or operators. Notwithstanding subsection (a) of
Exhibit G, such location shall be deemed to be the return location of the
Aircraft for purposes of such Exhibit G. Such parking shall be at Lessor's
risk and expense and Lessor shall pay all applicable storage, maintenance
and insurance fees and expenses. Lessee's obligation to arrange parking
shall be subject to Lessee and Lessor entering into an agreement prior to
the commencement of the storage period with the storage facility providing,
among other things, that Lessor shall bear all maintenance charges and
other costs incurred relating to such storage.

               (c) Return of Other Engines. In the event that any Engine
owned by Lessor shall not be installed on the Airframe at the time of
return hereunder, Lessee shall be required to return the Airframe hereunder
with an Acceptable Alternate Engine meeting the requirements of, and in
accordance with, Section 10 and Exhibit G hereto. Thereupon, Lessor will
transfer to Lessee the Engine constituting part of such Aircraft but not
installed on such Airframe at the time of the return of the Airframe.

               (d) Obligations Continue Until Return. If Lessee shall, for
any reason, fail to return the Aircraft at the time specified herein, all
obligations of Lessee under this Lease shall continue in effect with
respect to the Aircraft until the Aircraft is returned to Lessor and Lessee
shall pay to Lessor an amount equal to the average daily Basic Rent payable
by Lessee during the Term for each day after the end of the Term to but
excluding the day of such return; provided, however, that Lessee shall not
be responsible for Lessor's failure to accept return of the Aircraft in
accordance with this Section 5 in a timely manner or for any Rent with
respect to periods after Lessee has tendered the Aircraft for return in
accordance with this Lease. Any Rent owed to Lessor pursuant to this
Section 5(d) shall be payable upon acceptance of the Aircraft by Lessor or
on the last day of each calendar month following the last day of the Term
if the Aircraft has not been accepted earlier.

               SECTION 6.   LIENS.  Lessee will not directly or indirectly
create, incur, assume or suffer to exist any Lien on or with respect to the
Aircraft, title thereto or any interest therein or in this Lease, except
(i) the respective rights of Lessor as owner of the Aircraft and Lessee as
herein provided, the Lien of the Trust Indenture, the rights of any
Sublessee under a sublease permitted hereunder and any other rights of any
Person existing pursuant to the Operative Documents, (ii) the rights of
others under agreements or arrangements to the extent permitted by the
terms of Sections 7(b) and 8(b) hereof, (iii) Lessor Liens, Loan
Participant Liens and Indenture Trustee's Liens, (iv) Liens for Taxes of
Lessee (or any Sublessee) either not yet due or being contested in good
faith by appropriate proceedings so long as such proceedings do not involve
any material danger of the sale, forfeiture or loss of the Airframe or any
Engine or any interest therein, (v) materialmen's, mechanics', workmen's,
repairmen's, employees' or other like Liens arising in the ordinary course
of Lessee's (or, if a Sublease is then in effect, Sublessee's) business
(including those arising under maintenance agreements entered into in the
ordinary course of business) securing obligations that are not overdue for
a period of more than sixty (60) days or are being contested in good faith
by appropriate proceedings so long as such proceedings do not involve any
material danger of the sale, forfeiture or loss of the Airframe or any
Engine or any interest therein, (vi) Liens arising out of any judgment or
award against Lessee (or any Sublessee), unless the judgment secured shall
not, within sixty (60) days after the entry thereof, have been discharged,
vacated, reversed or execution thereof stayed pending appeal or shall not
have been discharged, vacated or reversed within sixty (60) days after the
expiration of such stay, (vii) any other Lien with respect to which Lessee
(or any Sublessee) shall have provided a bond, cash collateral or other
security adequate in the reasonable opinion of Lessor and (viii) Liens
approved in writing by Lessor. Lessee will promptly, at its own expense,
take (or cause to be taken) such actions as may be necessary duly to
discharge any such Lien not excepted above if the same shall arise at any
time.

               SECTION 7.   REGISTRATION, MAINTENANCE, OPERATION AND
REGISTRATION; POSSESSION AND SUBLEASES; INSIGNIA.

               (a)    Registration, Maintenance, Operation and Registration.

                      (1) Registration and Maintenance. Lessee, at its own
        cost and expense, shall (or shall cause any Sublessee to): (A)
        forthwith upon the delivery thereof hereunder, cause the Aircraft
        to be duly registered in the name of Lessor, and, subject to clause
        3 of this Section 7(a) and Section 7(d) of the Participation
        Agreement, to remain duly registered in the name of Lessor under
        the Transportation Code, provided that Lessor shall execute and
        deliver all such documents as Lessee (or any Sublessee) may
        reasonably request for the purpose of effecting and continuing
        such registration, and shall not register the Aircraft or permit
        the Aircraft to be registered under any laws other than the
        Transportation Code at any time except as provided in Section
        7(d) of the Participation Agreement and, unless the Lien of the
        Trust Indenture shall have been discharged, shall cause the Trust
        Indenture to be duly recorded and maintained of record as a first
        mortgage on the Aircraft; (B) maintain, service, repair and/or
        overhaul (or cause to be maintained, serviced, repaired and/or
        overhauled) the Aircraft so as to keep the Aircraft in as good an
        operating condition as when delivered by the Seller to Lessee,
        ordinary wear and tear excepted, and as may be necessary to
        enable the applicable airworthiness certification for the
        Aircraft to be maintained in good standing at all times (other
        than during temporary periods of storage or during maintenance or
        modification permitted hereunder) under the Transportation Code,
        except when all of Lessee's Airbus Model A330 aircraft powered by
        engines of the same type as those with which the Airframe shall
        be equipped at the time of such grounding and registered in the
        United States have been grounded by the FAA (although such
        certification need actually be maintained only during such
        periods as the Aircraft is registered in the United States), or
        the applicable laws of any other jurisdiction in which the
        Aircraft may then be registered from time to time in accordance
        with Section 7(d) of the Participation Agreement, utilizing,
        except during any period that a Sublease is in effect, the same
        manner and standard of maintenance, service, repair or overhaul
        used by Lessee with respect to similar aircraft operated by
        Lessee in similar circumstances and utilizing, during any period
        that a Sublease is in effect, the same manner and standard of
        maintenance, service, repair or overhaul used by the Sublessee
        with respect to similar aircraft operated by the Sublessee in
        similar circumstances; (C) maintain or cause to be maintained in
        English all records, logs and other materials required to be
        maintained in respect of the Aircraft by the FAA or the
        applicable regulatory agency or body of any other jurisdiction in
        which the Aircraft may then be registered; and (D) promptly
        furnish or cause to be furnished to Lessor and the Owner
        Participant such information as may be required to enable Lessor
        to file any reports required to be filed by Lessor or the Owner
        Participant with any governmental authority because of Lessor's
        ownership of the Aircraft.

                      (2) Operation. Lessee will not maintain, use,
        service, repair, overhaul or operate the Aircraft (or permit any
        Sublessee to maintain, use, service, repair, overhaul or operate
        the Aircraft) in violation of any law or any rule, regulation,
        order or certificate of any government or governmental authority
        (domestic or foreign) having jurisdiction over the Aircraft, or in
        violation of any airworthiness certificate, license or registration
        relating to the Aircraft issued by any such authority, except to
        the extent Lessee (or, if a Sublease is then in effect, any
        Sublessee) is contesting in good faith the validity or application
        of any such law, rule, regulation or order in any reasonable manner
        which does not involve any material risk of sale, forfeiture or
        loss of the Aircraft. Lessee will not operate the Aircraft, or
        permit any Sublessee to operate the Aircraft, in any area excluded
        from coverage by any insurance required by the terms of Section 11;
        provided, however, that the failure of Lessee to comply with the
        provisions of this sentence shall not give rise to an Event of
        Default hereunder if indemnification complying with Section 11(c)
        has been provided or where such failure is attributable to
        extraordinary circumstances involving an isolated occurrence or
        series of incidents not in the ordinary course of the regular
        operations of Lessee (or any Sublessee) such as a hijacking,
        medical emergency, equipment malfunction, weather condition,
        navigational error or other causes beyond the reasonable control of
        Lessee (or any Sublessee).

                      (3) Reregistration. At any time after the
        Depreciation Period, Lessor, upon Lessee's compliance with all of
        the terms of Section 7(d) of the Participation Agreement, shall, at
        the request and sole expense of Lessee, cooperate with Lessee to
        take all actions required to change the registration of the
        Aircraft to another country.

               (b) Possession and Subleases. Lessee will not, without the
prior written consent of Lessor, sublease or otherwise in any manner
deliver, transfer or relinquish possession of the Airframe or any Engine or
install or permit any Engine to be installed on any airframe other than the
Airframe or enter into any Wet Lease, and so long as Lessee (or any
Sublessee) shall comply with the provisions of Section 7(a) and Section 11
hereof, Lessee may (or may permit any Sublessee to), without the prior
written consent of Lessor:

                            (i) subject the Airframe and the Engines or
        engines then installed thereon to interchange agreements or any
        Engine to pooling or similar arrangements, in each case customary
        in the airline industry and entered into by Lessee (or, if a
        Sublease is then in effect, by Sublessee) in the ordinary course of
        its business; provided that (A) no such agreement or arrangement
        contemplates or requires the transfer of title to the Airframe, (B)
        if Lessor's title to any Engine shall be divested under any such
        agreement or arrangement, such divestiture shall be deemed to be an
        Event of Loss with respect to such Engine and Lessee shall (or
        shall cause Sublessee to) comply with Section 10(b) hereof in
        respect thereof and (C) any interchange agreement to which the
        Airframe may be subject shall be with a U.S. Air Carrier or a
        Foreign Air Carrier.

                            (ii) deliver possession of the Airframe or any
        Engine to the manufacturer thereof (or for delivery thereto) or to
        any organization (or for delivery thereto) for testing, service,
        repair, maintenance or overhaul work on the Airframe or Engine or
        any part of any thereof or for alterations or modifications in or
        additions to such Airframe or Engine to the extent required or
        permitted by the terms of Section 8(c) hereof;

                            (iii)install an Engine on an airframe owned by
        Lessee (or any Sublessee) free and clear of all Liens, except: (A)
        Permitted Liens and those which apply only to the engines (other
        than Engines), appliances, parts, instruments, appurtenances,
        accessories, furnishings and other equipment (other than Parts)
        installed on such airframe (but not to the airframe as an
        entirety), (B) the rights of third parties under interchange
        agreements or pooling or similar arrangements which would be
        permitted under clause (i) above, provided that Lessor's title to
        such Engine and, if any Equipment Notes shall be outstanding, the
        first priority Lien of the Trust Indenture shall not be divested or
        impaired as a result thereof and (C) mortgage liens or other
        security interests, provided that (as regards this clause (C)) the
        documents creating such mortgage liens or other security interests
        (or, if applicable, another written agreement governing such
        mortgage liens or other security interests) effectively provide
        that such Engine shall not become subject to the lien of such
        mortgage or security interest, notwithstanding the installation
        thereof on such airframe;

                            (iv) install an Engine on an airframe leased to
        Lessee (or any Sublessee) or purchased by Lessee (or any Sublessee)
        subject to a conditional sale or other security agreement, provided
        that (x) such airframe is free and clear of all Liens, except: (A)
        the rights of the parties to the lease or conditional sale or other
        security agreement covering such airframe, or their assignees and
        (B) Liens of the type permitted by clause (iii) of this paragraph
        (b) and (y) such lease, conditional sale or other security
        agreement effectively provides that such Engine shall not become
        subject to the lien of such lease, conditional sale or other
        security agreement, notwithstanding the installation thereof on
        such airframe;

                            (v) install an Engine on an airframe owned by
        Lessee (or any Sublessee), leased to Lessee (or any Sublessee) or
        purchased by Lessee (or any Sublessee) subject to a conditional
        sale or other security agreement under circumstances where neither
        clause (iii) nor clause (iv) of this paragraph (b) is applicable,
        provided that such installation shall be deemed an Event of Loss
        with respect to such Engine and Lessee shall (or shall cause any
        Sublessee to) comply with Section 10(b) hereof in respect thereof,
        Lessor not intending hereby to waive any right or interest it may
        have to or in such Engine under applicable law until compliance by
        Lessee with such Section 10(b);

                            (vi) to the extent permitted by Section 8(b)
        hereof, subject any appliances, Parts or other equipment owned by
        Lessor and removed from the Airframe or any Engine to any pooling
        arrangement referred to in Section 8(b) hereof;

                            (vii)subject (or permit any Sublessee to
        subject) the Airframe or any Engine to the Civil Reserve Air Fleet
        Program and transfer (or permit any Sublessee to transfer)
        possession of the Airframe or any Engine to the United States
        Government or any instrumentality or agency thereof pursuant to the
        Civil Reserve Air Fleet Program, so long as Lessee (or any
        Sublessee) shall (A) promptly notify Lessor upon subjecting the
        Airframe or any Engine to the Civil Reserve Air Fleet Program in
        any contract year and provide Lessor with the name and address of
        the Contracting Office Representative for the Air Mobility Command
        of the United States Air Force to whom notice must be given
        pursuant to Section 15 hereof and (B) promptly notify Lessor upon
        transferring possession of the Airframe or any Engine to the United
        States of America or any agency or instrumentality thereof pursuant to
        such program;

                            (viiifor a period not to extend beyond the end
        of the Term, enter into a Wet Lease for the Airframe and Engines or
        engines then installed thereon with any third party; provided that
        if Lessee (or any Sublessee) shall enter into any Wet Lease for a
        period of more than one year (including renewal options) Lessee
        shall provide Lessor written notice of such Wet Lease (such notice
        to be given prior to entering into such Wet Lease, if practicable,
        but in any event promptly after entering into such Wet Lease);

                            (ix) for a period not to extend beyond the end
        of the Term, transfer possession of the Airframe or any Engine to
        the United States Government or any instrumentality or agency
        thereof pursuant to a contract, a copy of which shall be provided
        to Lessor; or

                            (x) Lessee may, at any time in its sole
        discretion, enter into any sublease with (A) any Person domiciled
        in the United States, (B) after the Depreciation Period, any
        Permitted Sublessee or (C) after the Depreciation Period, any other
        Person approved in writing by Lessor, which approval shall not be
        unreasonably withheld; provided, however, that no sublease entered
        into pursuant to this clause (x) shall extend beyond the expiration
        of the Basic Term or any Renewal Term then in effect unless Lessee
        shall have irrevocably committed to purchase the Aircraft or renew
        the Lease in accordance with the terms hereof at the end of the
        Basic Term or Renewal Term, as the case may be, to a date beyond
        the latest permissible expiration date of such sublease; provided,
        further, with respect to a sublease under subclauses (B) or (C) of
        this clause (x), Lessee shall deliver to Lessor an opinion of
        counsel to the effect that (I) the obligations of Lessee and the
        rights and remedies of the Lessor under the Lease remain valid,
        binding and (subject to customary bankruptcy and equitable remedies
        exceptions and to other exceptions customary in such Opinions)
        enforceable; (II) the terms of the sublease constitute valid and
        binding obligations of the Sublessee and (subject to customary
        bankruptcy and equitable remedies exceptions and to other
        exceptions customary in such Opinions) enforceable against
        Sublessee (it being understood that such opinion may
        be an opinion as to the form of the Sublease only and may assume
        due authorization, execution, delivery, requisite approvals and
        absence of conflicts with laws, contracts or organizational
        documents) under the laws of the jurisdiction governing the
        sublease, (III) that there is no tort liability of the owner of an
        aircraft not in possession thereof under the laws of the
        jurisdiction of the proposed sublessee other than tort liability
        which might have been imposed on such owner under the laws of the
        United States or any state thereof (it being understood that in the
        event such opinion cannot be given such opinion requirement shall
        be waived if insurance reasonably satisfactory to Lessor, in its
        individual capacity, is provided at Lessee's expense) and (IV)
        unless Lessee shall have agreed to provide insurance covering the
        risk of requisition of use of the Aircraft by the government of the
        jurisdiction of the proposed sublessee reasonably satisfactory to
        the Owner Participant, that the laws of such jurisdiction require
        fair compensation by the government of such jurisdiction payable in
        currency freely convertible into Dollars for the loss of use of the
        Aircraft in the event of the requisition by such government of such
        use; and provided finally that, with respect to any sublease to any
        Affiliate of Lessee, (I) such sublessee shall be a Certificated Air
        Carrier and (II) Lessee shall deliver to Lessor an opinion of
        counsel to the effect that Lessee would be entitled to the benefits
        of Section 1110 of the Bankruptcy Code with respect to the Aircraft
        if such Affiliate were to be a debtor in a case under Chapter 11 of
        the Bankruptcy Code, such opinion to be subject to customary
        assumptions and qualifications. Lessee shall provide Lessor with a
        copy of any sublease which has a term of more than one (1) year.

               The rights of any Sublessee or other transferee who receives
possession by reason of a transfer permitted by this paragraph (b) (other
than the transfer of an Engine which is deemed an Event of Loss) shall be
subject and subordinate to, and any Sublease permitted by this paragraph
(b) shall be expressly subject and subordinate to, all the terms of this
Lease and Lessor's (and so long as the Trust Indenture is in effect, the
Indenture Trustee's (as Lessor's assignee) rights to repossess and to void
such Sublease upon such repossession, and Lessee shall remain primarily
liable hereunder for the performance of all of the terms of this Lease, and
the terms of any such Sublease shall not permit any Sublessee to take any
action not permitted to be taken by Lessee in this Lease with respect to
the Aircraft. No pooling agreement, sublease or other relinquishment of
possession of the Airframe or any Engine or Wet Lease shall in any way
discharge or diminish any of Lessee's obligations to Lessor hereunder or
constitute a waiver of Lessor's rights or remedies hereunder. Lessor
agrees, for the benefit of Lessee (and any Sublessee) and for the benefit
of any mortgagee or other holder of a security interest in any engine
(other than an Engine) owned by Lessee (or any Sublessee), any lessor of
any engine (other than an Engine) leased to Lessee (or any Sublessee) and
any conditional vendor of any engine (other than an Engine) purchased by
Lessee (or any Sublessee) subject to a conditional sale agreement or any
other security agreement, that no interest shall be created hereunder in
any engine so owned, leased or purchased and that none of Lessor, its
successors or assigns will acquire or claim, as against Lessee (or any
Sublessee) or any such mortgagee, lessor or conditional vendor or other
holder of a security interest or any successor or assignee of any thereof,
any right, title or interest in such engine as the result of such engine
being installed on the Airframe.

               Any Wet Lease or similar arrangement under which Lessee
maintains operational control of the Aircraft shall not constitute a
delivery, transfer or relinquishment of possession of the Aircraft for
purposes of this section. Lessor acknowledges that any consolidation or
merger of Lessee or conveyance, transfer or lease of all or substantially
all of Lessee's assets otherwise permitted by the Operative Documents shall
not be prohibited by this Section.

               (c) Insignia. On or prior to the Delivery Date, or as soon
as practicable thereafter, Lessee agrees to affix and maintain (or cause to
be affixed and maintained), at its expense, in the cockpit of the Airframe
adjacent to the airworthiness certificate therein and on each Engine a
nameplate bearing the inscription:

                                Leased From

        First Security Bank, National Association, as Owner Trustee, Lessor

and, for so long as the Airframe and each Engine shall be subject to the
Lien of the Trust Indenture, bearing the following additional inscription:


                                Mortgaged To

 State Street Bank and Trust Company of Connecticut, National Association,
                            as Indenture Trustee

(such nameplate to be replaced, if necessary, with a nameplate reflecting
the name of any successor Lessor or successor Indenture Trustee, in each
case as permitted under the Operative Documents). Except as above provided,
Lessee will not allow the name of any Person to be placed on the Airframe
or on any Engine as a designation that might be interpreted as a claim of
ownership; provided that nothing herein contained shall prohibit Lessee (or
any Sublessee) from placing its customary colors and insignia on the
Airframe or any Engine.

               SECTION 8.   REPLACEMENT AND POOLING OF PARTS; ALTERATIONS,
                            ----------------------------------------------
MODIFICATIONS AND ADDITIONS.
- ---------------------------

               (a) Replacement of Parts. Lessee, at its own cost and
expense, will promptly replace or cause to be replaced all Parts which may
from time to time be incorporated or installed in or attached to the
Airframe or any Engine and which may from time to time become worn out,
lost, stolen, destroyed, seized, confiscated, damaged beyond repair or
permanently rendered unfit for use for any reason whatsoever, except as
otherwise provided in paragraph (c) of this Section 8 or if the Airframe or
an Engine to which a Part relates has suffered an Event of Loss. In
addition, Lessee (or any Sublessee) may, at its own cost and expense,
remove in the ordinary course of maintenance, service, repair, overhaul or
testing, any Parts, whether or not worn out, lost, stolen, destroyed,
seized, confiscated, damaged beyond repair or permanently rendered unfit
for use, provided that Lessee (or any Sublessee), except as otherwise
provided in paragraph (c) of this Section 8, will, at its own cost and
expense, replace such Parts as promptly as practicable. All replacement
Parts shall be free and clear of all Liens (except for Permitted Liens and
pooling arrangements to the extent permitted by paragraph (b) of this
Section 8 and except in the case of replacement property temporarily
installed on an emergency basis) and shall be in as good operating
condition as, and shall have a value and utility at least equal to, the
Parts replaced assuming such replaced Parts were in the condition and
repair required to be maintained by the terms hereof. Except as otherwise
provided in paragraph (c) of this Section 8, all Parts at any time removed
from the Airframe or any Engine shall remain the property of Lessor, no
matter where located, until such time as such Parts shall be replaced by
Parts which have been incorporated or installed in or attached to the
Airframe or such Engine and which meet the requirements for replacement
Parts specified above. Immediately upon any replacement part becoming
incorporated or installed in or attached to the Airframe or any Engine as
above provided, without further act (subject only to Permitted Liens and
any pooling arrangement to the extent permitted by paragraph (b) of this
Section 8 and except in the case of replacement property temporarily
installed on an emergency basis), (i) title to such replacement Part shall
thereupon vest in Lessor, (ii) such replacement Part shall become subject
to this Lease and be deemed part of the Airframe or such Engine for all
purposes hereof to the same extent as the Parts originally incorporated or
installed in or attached to the Airframe or such Engine and (iii) title to
the replaced Part shall thereupon vest in Lessee (or, if a Sublease is then
in effect, any Sublessee), free and clear of all rights of Lessor, and
shall no longer be deemed a Part hereunder.

               (b) Pooling of Parts. Any Part removed from the Airframe or
any Engine as provided in paragraph (a) of this Section 8 may be subjected
by Lessee (or any Sublessee) to a normal pooling arrangement customary in
the airline industry of which Lessee (or, if a Sublease is then in effect,
any Sublessee) is a party entered into in the ordinary course of Lessee's
(or any Sublessee's) business; provided that the Part replacing such
removed Part shall be incorporated or installed in or attached to such
Airframe or Engine in accordance with such paragraph (a) as promptly as
practicable after the removal of such removed Part. In addition, any
replacement Part when incorporated or installed in or attached to the
Airframe or any Engine in accordance with such paragraph (a) may be owned
by any third party subject to such a normal pooling arrangement, provided
that Lessee (or any Sublessee), at its expense, as promptly thereafter as
practicable, either (i) causes title to such replacement Part to vest in
Lessor in accordance with such paragraph (a) by Lessee (or any Sublessee)
acquiring title thereto for the benefit of, and transferring such title to,
Lessor free and clear of all Liens except Permitted Liens (other than
pooling arrangements) or (ii) replaces such replacement Part by
incorporating or installing in or attaching to the Airframe or Engine a
further replacement Part owned by Lessee (or any Sublessee) free and clear
of all Liens except Permitted Liens (other than pooling arrangements) and
by causing title to such further replacement Part to vest in Lessor in
accordance with such paragraph (a).

               (c) Alterations, Modifications and Additions. Lessee, at its
own expense, will make (or cause to be made) such alterations and
modifications in and additions to the Airframe and Engines as may be
required from time to time to meet the applicable standards of the FAA or
any applicable regulatory agency or body of any other jurisdiction in which
the Aircraft may then be registered as permitted by Section 7(d) of the
Participation Agreement; provided, however, that Lessee (or, if a Sublease
is then in effect, any Sublessee) may, in good faith, contest the validity
or application of any such law, rule, regulation or order in any reasonable
manner which does not adversely affect Lessor or, so long as any Equipment
Notes are outstanding, the Indenture Trustee. In addition, Lessee (or any
Sublessee), at its own expense, may from time to time add further parts or
accessories and make such alterations and modifications in and additions to
the Airframe or any Engine as Lessee (or any Sublessee) may deem desirable
in the proper conduct of its business, including, without limitation,
removal of Parts which Lessee (or any Sublessee) has determined in its
reasonable judgment to be obsolete or no longer suitable or appropriate for
use on the Airframe or such Engine (such parts, "Obsolete Parts"); provided
that no such alteration, modification or addition shall materially diminish
the value, utility or remaining useful life of the Airframe or such Engine
below the value, utility or remaining useful life thereof immediately prior
to such alteration, modification or addition, assuming the Airframe or such
Engine was then in the condition required to be maintained by the terms of
this Lease, except that the value (but not the utility or remaining useful
life) of the Airframe or any Engine may be reduced by the value of Obsolete
Parts which shall have been removed so long as the aggregate value of all
Obsolete Parts which shall have been removed and not replaced shall not
exceed $750,000 in aggregate value at the time of removal. Title to all
Parts incorporated or installed in or attached or added to the Airframe or
an Engine as the result of such alteration, modification or addition
(except those parts which (x) Lessee has leased from others and (y) may be
removed by Lessee pursuant to the next sentence (the "Additional Parts"))
shall, without further act, vest in Lessor. Notwithstanding the foregoing
sentence, Lessee (or any Sublessee) may remove or suffer to be removed any
Additional Part, provided that such Additional Part (i) is in addition to,
and not in replacement of or substitution for, any Part originally
incorporated or installed in or attached to the Airframe or any Engine at
the time of delivery thereof hereunder or any Part in replacement of, or
substitution for, any such Part, (ii) is not required to be incorporated or
installed in or attached or added to the Airframe or any Engine pursuant to
the terms of Section 7 hereof or the first sentence of this paragraph (c)
and (iii) can be removed from the Airframe or such Engine without
diminishing or impairing the value, utility or remaining useful life which
the Airframe or such Engine would have had at the time of removal had such
alteration, modification or addition not occurred. Upon the removal by
Lessee (or Sublessee) of any Part as provided above, title thereto shall,
without further act, vest in Lessee (or any Sublessee, as the case may be)
and such Part shall no longer be deemed part of the Airframe or Engine from
which it was removed. Any Part not removed by Lessee (or any Sublessee) as
above provided prior to the return of the Airframe or Engine to Lessor
hereunder shall remain the property of Lessor.

               (d)    Certain Matters Regarding Passenger Convenience
Equipment. Lessee may install on the Airframe, subject to the requirements
of Section 8(c) above, Passenger Convenience Equipment that is (i) owned by
another Person and leased to Lessee, (ii) sold to Lessee by another Person
subject to a conditional sale contract or other retained security interest,
(iii) leased to Lessee pursuant to a lease which is subject to a security
interest in favor of another Person or (iv) installed on the Aircraft
subject to a license granted to Lessee by another Person, and in any such
case the Lessor and the Indenture Trustee will not acquire or claim, as
against any such other Person, any right, title or interest in any such
Passenger Convenience Equipment solely as a result of its installation on
the Airframe. Lessee agrees that if any such Person repossesses such
Passenger Convenience Equipment, Lessee will (or will cause such Person to)
restore the Aircraft to the condition it would have been in had the
installation of such Passenger Convenience Equipment not occurred.

               SECTION 9.   VOLUNTARY TERMINATION.
                            ---------------------

               (a)    Termination Event.
                      -----------------

               (i) Lessee shall have the right to elect to terminate this
        Lease (x) on any Lease Period Date occurring on or after the close
        of the calendar year in which the seventh (7th) anniversary of the
        Delivery Date occurs if Lessee shall have made the good faith
        determination, which shall be evidenced by a certificate of a
        responsible officer of Lessee, that the Aircraft is obsolete or
        surplus to its needs or (y) on the tenth, thirteenth and sixteenth
        anniversaries of the Delivery Date.

               (ii) Lessee shall give to Lessor at least one hundred twenty
        (120) days revocable advance written notice of Lessee's intention
        to so terminate this Lease (any such notice, a "Termination
        Notice") specifying (A) the Lease Period Date on which Lessee
        intends to terminate this Lease in accordance with this Section 9
        (such specified date, a "Termination Date"), (B) either (I) that
        Lessee has determined that the Aircraft is obsolete or surplus to
        its needs or (II) that it is exercising its termination option
        pursuant to Section 9(a)(i)(y) and (C) in the case of a Termination
        under Section 9(a)(i)(y) whether Lessee elects to purchase the
        Aircraft pursuant to Section 9(d). Any Termination Notice shall
        become irrevocable fifteen (15) days prior to the Termination Date.

               (b) Optional Sale of the Aircraft; Lessor Retention Option;
Revocation of Termination Notice. In the event that Lessee shall have
exercised its right to terminate this Lease under Section 9(a)(i)(y) but
shall not have elected to purchase the Aircraft pursuant to Section 9(d),
or Lessee shall have elected to terminate this Lease pursuant to Section
9(a)(i)(x), then during the period from the giving of the Termination
Notice until the proposed Termination Date (unless Lessee shall have
revoked the Termination Notice specifying such proposed Termination Date or
Lessor shall have irrevocably elected to retain the Aircraft pursuant to
this Section 9(b)), Lessee, as agent for Lessor and at no expense to
Lessor, shall use commercially reasonable efforts to obtain bids for the
purchase of the Aircraft and, in the event it receives any bid, Lessee
shall, within five (5) Business Days after receipt thereof and at least ten
(10) Business Days prior to the proposed Termination Date, certify to
Lessor in writing the amount and terms of such bid, and the name and
address of the party or parties (who shall not be Lessee or any Affiliate
of Lessee or any Person with whom Lessee or any such Affiliate has an
arrangement or understanding regarding the future use of the Aircraft by
Lessee or any such Affiliate but who may be the Owner Participant, any
Affiliate thereof or any Person contacted by the Owner Participant)
submitting such bid. Subject to the next succeeding sentence, on or before
the Termination Date, subject to the release of all mortgage and security
interests with respect to the Aircraft under the Trust Indenture: (1)
Lessee shall deliver the Aircraft, or cause the Aircraft to be delivered,
to the bidder(s), if any, which shall have submitted the highest bid
therefor at least ten (10) Business Days prior to such Termination Date, in
the same manner and in the same condition and otherwise in accordance with
all the terms of this Lease as if delivery were made to Lessor pursuant to
Section 5, and shall duly transfer to Lessor title to any engines not owned
by Lessor all in accordance with the terms of Section 5, (2) Lessor shall
comply with the terms of the Trust Indenture and shall, without recourse or
warranty (except as to the absence of Lessor Liens), subject to prior or
concurrent payment by Lessee of all amounts due under clause (3) of this
sentence, sell all of Lessor's right, title and interest in and to the
Aircraft for cash in Dollars to such bidder(s), the total sales price
realized at such sale to be retained by Lessor and (3) Lessee shall
simultaneously pay or cause to be paid to Lessor in funds of the type
specified in Section 3(e) hereof, an amount equal to the sum of (A) the
excess, if any, of (i) the Termination Value for the Aircraft, computed as
of the Termination Date, over (ii) the sales price of the Aircraft sold by
Lessor after deducting the reasonable expenses incurred by Lessor in
connection with such sale, (B) all unpaid Basic Rent with respect to the
Aircraft due prior to such Termination Date and, if such Basic Rent is
payable in arrears on such Termination Date as indicated on Exhibit B, on
such Termination Date, and all unpaid Supplemental Rent due on or prior to
the Termination Date with respect to the Aircraft and (C) the Make-Whole
Amount, if any, due on the Equipment Notes, and upon such payment Lessor
simultaneously will transfer to Lessee, without recourse or warranty
(except as to the absence of Lessor Liens), all of Lessor's right, title
and interest in and to any Engines constituting part of the Aircraft which
were not sold with the Aircraft. Notwithstanding the preceding sentence,
Lessor may, if Lessee has not revoked the Termination Notice, elect to
retain title to the Aircraft. If Lessor so elects, Lessor shall give to
Lessee irrevocable written notice of such election within thirty (30) days
of its receipt of a Termination Notice accompanied by an irrevocable
undertaking by the Owner Participant to make available to the Lessor for
payment to the Indenture Trustee on the Termination Date the amount
required to pay in full the unpaid principal amount of the Equipment Notes
outstanding on the Termination Date plus interest accrued thereon through
the Termination Date together with the Make-Whole Amount, if any, due on
the Equipment Notes, if the same is not otherwise paid. Upon receipt of
notice of such an election by Lessor and the accompanying undertaking by
the Owner Participant, Lessee shall cease its efforts to obtain bids as
provided above and shall reject all bids theretofore or thereafter
received. On the Termination Date, Lessor shall (subject to the payment by
Lessee of all Rent due on or prior to such date as set forth below) pay in
full the unpaid principal amount of the Equipment Notes outstanding on the
Termination Date plus interest accrued thereon through the Termination Date
together with all Make-Whole Amount, if any, due on the Equipment Notes
and, so long as the Equipment Notes are paid as aforesaid, Lessee shall
deliver the Airframe and Engines or engines to Lessor in accordance with
Section 5 and shall pay all Basic Rent due prior to the Termination Date
and, if such Basic Rent is payable in arrears on such Termination Date as
indicated on Exhibit B, on such Termination Date, and all Supplemental Rent
(other than Make-Whole Amount or Termination Value) due on or prior to the
Termination Date. If no sale shall have occurred on the Termination Date
and Lessor has not made the payment contemplated by the preceding sentence
and thereby caused this Lease to terminate, or if Lessee revokes its
Termination Notice, this Lease shall continue in full force and effect as
to the Aircraft, Lessee shall pay the reasonable costs and expenses
incurred by the Owner Participant and Lessor (unless such failure to
terminate the Lease is a consequence of the failure of Lessor or the Owner
Participant without due cause to make, or cause to be made, the payment
referred to in the immediately preceding sentence, in which case Lessor and
the Owner Participant shall be responsible for damages), if any, in
connection with preparation for such sale and Lessee may give one or more
additional Termination Notices in accordance with Section 9(a), subject to
the last sentence of this Section 9(b). In the event of any such sale or
such retention of the Aircraft by Lessor and upon compliance by Lessee with
the provisions of this paragraph, the obligation of Lessee to pay Basic
Rent or any other amounts hereunder shall cease to accrue and this Lease
shall terminate. Lessor may, but shall be under no duty to, solicit bids,
inquire into the efforts of Lessee to obtain bids or otherwise take any
action in connection with any such sale other than to transfer (in
accordance with the foregoing provisions) to the purchaser named in the
highest bid certified by Lessee to Lessor all of Lessor's right, title and
interest in the Aircraft, against receipt of the payments provided herein.
Lessee may revoke a Termination Notice given pursuant to Section 9(a) no
more than two (2) times during the Term.

               (c) Termination as to Engines; Replacement. Lessee shall
have the right at its option at any time during the Term, on at least
thirty (30) days prior written notice, to terminate this Lease with respect
to any Engine. In such event, and prior to the date of such termination,
Lessee shall replace such Engine hereunder by complying with the terms of
Section 10(b) to the same extent as if an Event of Loss had occurred with
respect to such Engine, and Lessor shall transfer such right, title and
interest as it may have to the replaced Engine as provided in Section 5(b).
No termination of this Lease with respect to any Engine as contemplated by
this Section 9(c) shall result in any reduction of Basic Rent.

               (d) Special Purchase Options. If Lessee exercises its right
to terminate this Lease under Section 9(a)(1)(y), gives its notice pursuant
to Section 9(a)(ii) to purchase the Aircraft pursuant to this Section 9(d)
and such notice becomes irrevocable, then on the Termination Date specified
in Section 9(a), Lessee shall purchase the Aircraft at the greater of (i)
the Termination Value on the Termination Date, or (ii) its fair market
sales value on the Termination Date (determined in accordance with Section
19(c) hereof), provided that Lessee shall have also paid the amounts
specified in (A) and (B) of the following sentence. In such event, Lessor
shall, without recourse or warranty (except as to the absence of Lessor
Liens), sell the Aircraft to Lessee in exchange for the payment in
immediately available funds in an amount equal to the greater of (x) the
Termination Value for the Aircraft, computed as of the Termination Value
Date, or (y) the fair market sales value of the Aircraft on the Termination
Date, provided that on such date the Lessee shall have also paid to the
Lessor the sum of (A) all unpaid Basic Rent with respect to the Aircraft
due on or prior to such Termination Date (other than Basic Rent payable in
advance and due on the Termination Date) and all unpaid Supplemental Rent
with respect to the Aircraft due on or prior to such Termination Date plus
(B) all reasonable expenses incurred by Lessor and the Owner Participant in
connection with such sale. Upon payment in full of the amounts required to
be paid and the performance of all acts required to be performed by Lessee
pursuant to the preceding sentence, (i) the obligation of Lessee to pay
Basic Rent hereunder with respect to the Aircraft for any period commencing
on or after the Termination Date shall terminate with respect to the
Aircraft, (ii) this Lease shall terminate on the Termination Date, (iii)
Lessor will transfer to or at the direction of Lessee, without recourse or
warranty (except as to the absence of Lessor Liens), all of Lessor's right,
title and interest in the Airframe and Engines and furnish to or at the
direction of the Lessee a bill of sales in form and substance reasonably
satisfactory to Lessee, evidencing such transfer. Notwithstanding the
foregoing, Lessee may, in accordance with Section 7(u) of the Participation
Agreement, assume the principal amount of the Equipment Notes then
outstanding on any Termination Date specified in Section 9(a), in which
event the Lessee will receive a credit against the purchase price otherwise
payable pursuant to this Section 9(d) in an amount equal to the principal
amount of Equipment Notes so assumed.

               SECTION 10.  LOSS, DESTRUCTION, REQUISITION, ETC.

               (a) Event of Loss with Respect to the Aircraft. Upon the
occurrence of an Event of Loss with respect to the Airframe or the Airframe
and the Engines and/or engines then installed thereon, Lessee shall
forthwith (and in any event, within fifteen (15) days after such
occurrence) give Lessor written notice of such Event of Loss, and, within
sixty (60) days after such Event of Loss, Lessee shall give Lessor written
notice of its election to perform one of the following options (it being
agreed that if Lessee shall not have given such notice of election within
such period, Lessee shall be deemed to have elected the option set forth in
clause (i) below). Lessee may elect either to:

                            (i) make the payments specified in this clause
        (i), in which event not later than the earlier of (x) the Business
        Day next succeeding the 120th day following the occurrence of such
        Event of Loss or (y) an earlier Business Day irrevocably specified
        fifteen (15) days in advance by notice from Lessee to Lessor and
        the Indenture Trustee (the "Loss Payment Date"), Lessee shall pay
        or cause to be paid to Lessor in funds of the type specified in
        Section 3(e) hereof, an amount equal to the Termination Value of
        the Aircraft corresponding to the Termination Value Date occurring
        on or immediately following the Loss Payment Date (the
        "Determination Date"); provided that in any instance in which the
        applicable Loss Payment Date shall occur after the final day of the
        Term, the Determination Date shall be the last Termination Value
        Date in the Term, and the Termination Value shall be reduced by any
        amount of Basic Rent due on the Determination Date that has
        actually been paid;

                            (ii) substitute an aircraft or an airframe or
        an airframe and one or more engines, as the case may be; provided
        that, if Lessee does not perform its obligation to effect such
        substitution in accordance with this Section 10(a), during the
        period of time provided herein, then Lessee shall pay or cause to
        be paid to Lessor on the Business Day next succeeding the 120th
        day following the occurrence of such Event of Loss the amount
        specified in clause (i) above.

               At such time as Lessor shall have received the amounts
specified in clause (i) above, together with all other amounts that then
may be due hereunder (including, without limitation, all Basic Rent due
before the date of such payment and all Supplemental Rent), under the
Participation Agreement and under the Tax Indemnity Agreement, (1) the
obligation of Lessee to pay the installments of Basic Rent shall cease to
accrue, (2) this Lease shall terminate, (3) Lessor will comply with the
terms of the Trust Indenture and transfer to or at the direction of Lessee,
without recourse or warranty (except as to the absence of Lessor Liens),
all of Lessor's right, title and interest in and to the Airframe and any
Engines subject to such Event of Loss, as well as any Engines not subject
to such Event of Loss, and furnish to or at the direction of Lessee a bill
of sale in form and substance reasonably satisfactory to Lessee (or any
Sublessee), evidencing such transfer and (4) Lessee will be subrogated to
all claims of Lessor, if any, against third parties, for damage to or loss
of the Airframe and any Engines which were subject to such Event of Loss to
the extent of the then insured value of the Aircraft.

               In the event Lessee shall elect to substitute an aircraft
(or an airframe or an airframe and one or more engines, as the case may be)
Lessee shall, at its sole expense, not later than the Business Day next
succeeding the 120th day following the occurrence of such Event of Loss,
(A) convey or cause to be conveyed to Lessor and to be leased by Lessee
hereunder, an aircraft (or an airframe or an airframe and one or more
engines which, together with the Engines constituting a part of the
Aircraft but not installed thereon at the time of such Event of Loss
constitute the Aircraft) free and clear of all Liens (other than Permitted
Liens) and having a value, utility and remaining useful life at least equal
to the Aircraft subject to such Event of Loss assuming that the Aircraft
had been maintained in accordance with this Lease and (B) prior to or at
the time of any such substitution, Lessee (or any Sublessee), at its own
expense, will (1) furnish Lessor with a full warranty bill of sale and a
Federal Aviation Administration bill of sale, in form and substance
reasonably satisfactory to Lessor, evidencing such transfer of title, (2)
cause a Lease Supplement and a Trust Supplement to be duly executed by
Lessee and filed for recording pursuant to the Transportation Code, or the
applicable laws, rules and regulations of any other jurisdiction in which
the Airframe may then be registered as permitted by Section 7(d) of the
Participation Agreement, (3) cause a financing statement or statements with
respect to such substituted property to be filed in such place or places as
are deemed necessary or desirable by Lessor to perfect its and the
Indenture Trustee's interest therein and herein, (4) furnish Lessor with
such evidence of compliance with the insurance provisions of Section 11
with respect to such substituted property as Lessor may reasonably request,
(5) furnish Lessor with copies of the documentation required to be provided
by Lessee pursuant to Section 5.06 of the Trust Indenture, and Lessor
simultaneously will comply with the terms of the Trust Indenture and
transfer to or at the direction of Lessee, without recourse or warranty
(except as to the absence of Lessor Liens), all of Lessor's right, title
and interest, if any, in and to the Aircraft or the Airframe and one or
more Engines, as the case may be, with respect to which such Event of Loss
occurred and furnish to or at the direction of Lessee a bill of sale in
form and substance reasonably satisfactory to Lessee (or any Sublessee),
evidencing such transfer, (6) furnish Lessor with an opinion of counsel
(which shall be Skadden, Arps, Slate, Meagher & Flom LLP or Skadden, Arps,
Slate, Meagher & Flom (Illinois) and, if not, other counsel chosen by
Lessee and reasonably acceptable to Lessor) reasonably satisfactory to
Lessor to the effect that Lessor and the Indenture Trustee will be entitled
to the benefits of Section 1110 of the U.S. Bankruptcy Code with respect to
the substitute aircraft, provided that such opinion need not be delivered
to the extent that immediately prior to such substitution the benefits of
Section 1110 of the U.S. Bankruptcy Code were not, solely by reason of a
change in law or governmental interpretation thereof after the date hereof,
available to Lessor and, so long as any Equipment Notes are outstanding,
the Indenture Trustee (it being agreed that such opinion may contain
customary qualifications and assumptions) and (7) Lessee will be subrogated
to all claims of Lessor, if any, against third parties for damage to or
loss of the Airframe and any Engine which were subject to such Event of
Loss to the extent of the then insured value of the Aircraft. For all
purposes hereof, the property so substituted shall after such transfer be
deemed part of the property leased hereunder and shall be deemed an
"Aircraft", "Airframe" and "Engine", as the case may be, as defined herein.
No Event of Loss with respect to the Airframe or the Airframe and the
Engines or engines then installed thereon for which substitution has been
elected pursuant to Section 10(a)(ii) hereof shall result in any reduction
in Basic Rent.

               (b) Event of Loss with Respect to an Engine. Upon the
occurrence of an Event of Loss with respect to an Engine under
circumstances in which there has not occurred an Event of Loss with respect
to the Airframe, Lessee shall forthwith (and in any event, within fifteen
days after such occurrence) give Lessor written notice thereof and shall,
within one hundred twenty (120) days after the occurrence of such Event of
Loss, convey or cause to be conveyed to Lessor, as replacement for the
Engine with respect to which such Event of Loss occurred, title to an
Acceptable Alternate Engine. Prior to or at the time of any such
conveyance, Lessee, at its own expense, will (i) furnish Lessor with a
warranty (as to title) bill of sale, in form and substance reasonably
satisfactory to Lessor, with respect to such Acceptable Alternate Engine,
(ii) cause a Lease Supplement and Trust Supplement to be duly executed by
Lessee and to be filed for recording pursuant to the Transportation Code,
or the applicable laws, rules and regulations of any other jurisdiction in
which the Airframe may then be registered as permitted by Section 7(d) of
the Participation Agreement, (iii) furnish Lessor with such evidence of
compliance with the insurance provisions of Section 11 hereof with respect
to such replacement engine as Lessor may reasonably request and furnish
Lessor with copies of the documentation required to be provided by Lessee
pursuant to Section 5.06 of the Trust Indenture, and Lessor will comply
with the terms of the Trust Indenture and transfer to or at the direction
of Lessee without recourse or warranty (except as to absence of Lessor
Liens) all of Lessor's right, title and interest, if any, in and to (A) the
Engine with respect to which such Event of Loss occurred and furnish to or
at the direction of Lessee a bill of sale in form and substance reasonably
satisfactory to Lessee, evidencing such transfer and (B) all claims, if
any, against third parties, for damage to or loss of the Engine subject to
such Event of Loss, and such Engine shall thereupon cease to be the Engine
leased hereunder. For all purposes hereof, each such replacement engine
shall, after such conveyance, be deemed part of the property leased
hereunder, and shall be deemed an "Engine". No Event of Loss with respect
to an Engine under the circumstances contemplated by the terms of this
paragraph (b) shall result in any reduction in Basic Rent.

               (c) Application of Payments from Governmental Authorities
for Requisition of Title, etc. Any payments (other than insurance proceeds
the application of which is provided for in Section 11) received at any
time by Lessor or by Lessee from any governmental authority or other Person
with respect to an Event of Loss will be applied as follows:

                            (i) if payments are received with respect to
        the Airframe (or the Airframe and any Engine or engines then
        installed thereon), (A) unless the same are replaced pursuant to
        the last paragraph of Section 10(a), after reimbursement of Lessor
        (as provided in Section 7.01 of the Trust Agreement) for reasonable
        costs and expenses, so much of such payments remaining as shall not
        exceed the Termination Value required to be paid by Lessee pursuant
        to Section 10(a), shall be applied in reduction of Lessee's
        obligation to pay Termination Value, if not already paid by Lessee,
        or, if already paid by Lessee, shall be applied to reimburse Lessee
        for its payment of Termination Value, and following the foregoing
        application, the balance, if any, of such payments will be paid
        over to, or retained by Lessee, provided that Lessor shall be
        entitled to so much of the excess, if any, of such payment over the
        greater of (x) the Termination Value and (y) the fair market value
        of the Aircraft as Lessor shall demonstrate to Lessee's
        reasonable satisfaction is attributable to compensation for loss
        of Lessor's interest in the Aircraft as distinguished from the
        loss of use of the Aircraft; or (B) if such property is replaced
        pursuant to the last paragraph of Section 10(a), such payments
        shall be paid over to, or retained by, Lessee; and

                            (ii) if such payments are received with respect
        to an Engine under circumstances contemplated by Section 10(b)
        hereof, so much of such payments remaining after reimbursement of
        Lessor (as provided for in Section 7.01 of the Trust Agreement) for
        reasonable costs and expenses shall be paid over to, or retained
        by, Lessee.

               (d) Requisition for Use of the Aircraft by the United States
Government or the Government of Registry of the Aircraft. In the event of
the requisition for use of the Airframe and the Engines or engines
installed on the Airframe during the Term by the United States Government
or any other government of registry of the Aircraft or any instrumentality
or agency of any thereof, Lessee shall promptly notify Lessor of such
requisition, and all of Lessee's obligations under this Lease with respect
to the Aircraft shall continue to the same extent as if such requisition
had not occurred (except to the extent that any failure or delay in
repairing or maintaining the Aircraft shall have been caused by such
requisition), provided that if such Airframe and Engines or engines
installed thereon are not returned by such government prior to the end of
the Term, Lessee shall be obligated to return the Airframe and such Engines
or engines to Lessor pursuant to, and in all other respects in compliance
with the provisions of, Section 5 promptly on the date of such return by
such government. If, in the event of any such requisition, Lessee shall
fail to return the Aircraft on or before the thirtieth (30th) day beyond
the end of the Term, such failure shall constitute an Event of Loss which
shall be deemed to have occurred on the last day of the Term and in such
event Lessee shall make the payment contemplated by Section 10(a)(i) in
respect of such Event of Loss; provided, however, that Lessor may notify
Lessee in writing on or before the twentieth (20th) day prior to the last
day of the Term that, in the event Lessee shall fail by reason of such
requisition to return the Airframe and such Engines or engines on or before
the thirtieth day beyond the end of the Term, such failure shall not be
deemed an Event of Loss. Upon the giving of such notice and such failure to
return by the thirtieth (30th) day beyond the end of the Term, Lessee shall
be relieved of all of its obligations pursuant to the provisions of Section
5 (but not under any other Section), except that if any engine not owned by
Lessor shall then be installed on the Airframe, Lessee will, at no cost to
Lessor, furnish, or cause to be furnished, to Lessor a full warranty (as to
title) bill of sale with respect to each such engine, in form and substance
reasonably satisfactory to Lessor (together with an opinion of counsel
(which may be Lessee's General Counsel, Deputy General Counsel, Associate
General Counsel or Assistant General Counsel) to the effect that such full
warranty bill of sale has been duly authorized and delivered and is
enforceable in accordance with its terms and that such engines are free and
clear of Liens other than Lessor Liens, Loan Participant Liens and
Indenture Trustee Liens), against receipt from Lessor of a bill of sale
evidencing the transfer, without recourse or warranty (except as to the
absence of Lessor Liens), by Lessor to Lessee or its designee of all of
Lessor's right, title and interest in and to any Engine constituting part
of the Aircraft but not then installed on the Airframe. All payments
received by Lessor or Lessee from such government for the use of such
Airframe and Engines or engines during the Term shall be paid over to, or
retained by, Lessee (or, if directed by Lessee, any Sublessee); and all
payments received by Lessor or Lessee from such government for the use of
such Airframe and Engines or engines after the end of the Term shall be
paid over to, or retained by, Lessor unless Lessee shall have exercised its
purchase option hereunder, in which case such payments shall be made to
Lessee.

               (e) Requisition for Use of an Engine by the United States
Government or the Government of Registry of the Aircraft. In the event of
the requisition for use of an Engine by the United States Government or any
other government of registry of the Aircraft or any agency or
instrumentality of any thereof (other than in the circumstances
contemplated by paragraph (d)), Lessee shall replace such Engine hereunder
by complying (or causing any Sublessee to comply) with the terms of Section
10(b) to the same extent as if an Event of Loss had occurred with respect
thereto, and, upon compliance with Section 10(b) hereof, any payments
received by Lessor or Lessee from such government with respect to such
requisition shall be paid over to, or retained by, Lessee.

               (f) Application of Payments During Existence of Event of
Default. Any amount referred to in this Section 10 which is payable to or
retainable by Lessee (or any Sublessee) shall not be paid to or retained by
Lessee (or such Sublessee) if at the time of such payment or retention an
Event of Default has occurred and is continuing, but shall be held by or
paid over to Lessor as security for the obligations of Lessee (or such
Sublessee) under this Lease and, if an Event of Default has occurred and is
continuing hereunder, applied against Lessee's obligations hereunder as and
when due. At such time as there shall not be continuing any such Event of
Default, such amount shall be paid to Lessee (or such Sublessee) to the
extent not previously applied in accordance with the preceding sentence.


               SECTION 11.  INSURANCE.
                            ---------

               (a) Lessee's Obligation to Insure. Lessee shall comply with,
or cause to be complied with, each of the provisions of Exhibit H, which
provisions are hereby incorporated by this reference as if set forth in
full herein.

               (b) Additional Insurance by Lessor and Lessee. Lessee (and
any Sublessee) may at its own expense carry insurance with respect to its
interest in the Aircraft in amounts in excess of that required to be
maintained by this Section 11; the Owner Participant may carry for its own
account at its sole cost and expense insurance with respect to its interest
in the Aircraft, provided that such insurance does not prevent Lessee (or
any Sublessee) from carrying the insurance required or permitted by this
Section 11 or adversely affect such insurance or the cost thereof.

               (c) Indemnification by Government in Lieu of Insurance.
Notwithstanding any provisions of this Section 11 requiring insurance,
Lessor agrees to accept, in lieu of insurance against any risk with respect
to the Aircraft, indemnification from, or insurance provided by, the United
States Government or any agency or instrumentality thereof, or, upon the
written consent of Lessor, other government of registry of the Aircraft or
agency or instrumentality thereof, against such risk in an amount which,
when added to the amount of insurance against such risk maintained by
Lessee (or any Sublessee) shall be at least equal to the amount of
insurance against such risk otherwise required by this Section 11 (taking
into account self-insurance permitted by Exhibit H hereto).

               (d) Application of Payments During Existence of an Event of
Default. Any amount referred to in paragraph (b) of Exhibit H hereto which
is payable to or retainable by Lessee (or any Sublessee) shall not be paid
to or retained by Lessee (or any Sublessee) if at the time of such payment
or retention an Event of Default has occurred and is continuing, but shall
be held by or paid over to Lessor as security for the obligations of Lessee
under this Lease and, if Lessor declares this Lease to be in default
pursuant to Section 15 hereof, applied against Lessee's obligations
hereunder as and when due. At such time as there shall not be continuing
any such Event of Default, such amount shall be paid to Lessee to the
extent not previously applied in accordance with the preceding sentence.

               SECTION 12.  INSPECTION.  At all reasonable times and upon at
least 15 days prior written notice to Lessee, the Owner Participant or the
Indenture Trustee, or their respective authorized representatives, may
inspect the Aircraft and inspect and make copies of the books and records
of Lessee and any Sublessee required to be maintained by the Federal
Aviation Administration or the regulatory agency or body of another
jurisdiction in which the Aircraft is then registered relating to the
maintenance of the Aircraft (at Lessor's, the Owner Participant's or the
Indenture Trustee's risk and expense, as the case may be) and shall keep
any information or copies obtained thereby confidential and shall not
disclose the same to any Person, except (A) to the Lessor, the Note Holders
and to prospective and permitted transferees of Lessor's, the Owner
Participant's, the Note Holders' or the Indenture Trustee's interest (and
such prospective and permitted transferee's counsel, independent insurance
advisors or other agents) who agree to hold such information confidential,
(B) to Lessor's, the Owner Participant's, the Note Holders' or the
Indenture Trustee's counsel, independent insurance advisors or other agents
who agree to hold such information confidential, or (C) as may be required
by any statute, court or administrative order or decree or governmental
ruling or regulation, provided, however, that any and all disclosures
permitted by clause (C) above shall be made only to the extent necessary to
meet the specific requirements or needs of the Persons for whom such
disclosures are hereby permitted. Any such inspection of the Aircraft shall
be subject to Lessee's safety and security rules applicable to the location
of the Aircraft, shall be a visual, walk-around inspection of the interior
and exterior of the Aircraft and shall not include opening any panels, bays
or the like without the express consent of Lessee (except in connection
with a heavy maintenance visit when a panel, bay or the like is scheduled
or required to be opened), which consent Lessee may in its sole discretion
withhold; provided that no exercise of such inspection right shall
interfere with the normal operation or maintenance of the Aircraft by, or
the business of, Lessee (or any Sublessee). Upon receipt by Lessee of a
written request from the Owner Participant specifying that the Owner
Participant desires to have an authorized representative observe the next
scheduled heavy maintenance visit to be performed on the Aircraft during
the Term, Lessee shall cooperate with the Owner Participant to enable the
Owner Participant's representative to observe such scheduled maintenance to
be performed on the Aircraft during the Term; provided that the Owner
Participant's authorized representative shall merely observe such scheduled
heavy maintenance visit, shall not interfere with or extend in any manner
the normal conduct or duration of the scheduled heavy maintenance visit,
and shall not be entitled to direct any of the work performed in connection
with such scheduled heavy maintenance visit. Neither the Owner Participant
nor the Indenture Trustee shall have any duty to make any such inspection
nor shall either of them incur any liability or obligation by reason of not
making such inspection. Except during the final six (6) months of the Term
or during the continuance of an Event of Default, all inspections by the
Owner Participant and its authorized representatives or the Indenture
Trustee and its authorized representatives provided for under this Section
12 shall, in regard to each of the Owner Participant and the Indenture
Trustee, be limited to one (1) inspection of any kind contemplated by this
Section 12 during any calendar year. During the last three months of the
Term (unless Lessee shall have elected to purchase the Aircraft or renew
this Lease in accordance with the terms of this Lease), with reasonable
notice, Lessee will cooperate and cause any Sublessee to cooperate, at
Lessor's sole cost, in all reasonable respects with the efforts of Lessor
to sell or lease the Aircraft, including, without limitation, permitting
prospective purchasers or lessees to inspect the Aircraft, any maintenance
records relating to the Aircraft then required to be retained by the FAA or
by the comparable government of registry of the Aircraft, all in accordance
with the provisions set forth above; provided that any such cooperation
shall not interfere with the normal operation or maintenance of the
Aircraft by, or the business of, Lessee or any Sublessee.

               SECTION 13. ASSIGNMENT. Except as otherwise provided herein,
Lessee will not, without prior written consent of Lessor, assign in whole
or in part any of its rights or obligations hereunder. Lessor agrees that
it will not assign or convey its right, title and interest in and to this
Lease or the Aircraft except as provided herein, in the Trust Indenture,
the Trust Agreement, in the Participation Agreement or in any other
Operative Document. Subject to the foregoing, the terms and provisions of
this Lease shall be binding upon and inure to the benefit of Lessor and
Lessee and their respective successors and permitted assigns.

               SECTION 14. EVENTS OF DEFAULT. Each of the following events
shall constitute an Event of Default (whether any such event shall be
voluntary or involuntary or come about or be effected by operation of law
or pursuant to or in compliance with any judgment, decree or order of any
court or any order, rule or regulation of any administrative or
governmental body) and each such Event of Default shall continue so long
as, but only as long as, it shall not have been remedied:

               (a) Lessee shall not have made a payment of (i) Basic Rent
within five (5) Business Days after the same shall have become due or (ii)
Termination Value within ten (10) Business Days after receipt by Lessee of
written notice that the same is past due; or

               (b) Lessee shall have failed to make a payment of
Supplemental Rent (other than Termination Value) after the same shall have
become due and such failure shall continue for thirty (30) days after
Lessee's receipt of written demand therefor by the party entitled thereto
(provided that any failure to pay any amount owed by Lessee under the Tax
Indemnity Agreement or any failure of Lessee to pay to Lessor or the Owner
Participant when due any Excluded Payments shall not constitute an Event of
Default unless notice is given by the Owner Participant to Lessee and the
Indenture Trustee that such failure shall constitute an Event of Default);
or

               (c) Lessee shall have failed to perform or observe (or
caused to be performed and observed) in any material respect any covenant
or agreement (except the covenants set forth in the Tax Indemnity
Agreement) to be performed or observed by it under any Operative Document,
and such failure shall continue unremedied for a period of thirty (30) days
after receipt by Lessee of written notice thereof from Lessor or the
Indenture Trustee; provided, however, that if Lessee shall have undertaken
to cure any such failure and, notwithstanding the diligence of Lessee in
attempting to cure such failure, such failure is not cured within said
thirty (30) day period but is curable with future due diligence, there
shall exist no Event of Default under this Section 14 so long as Lessee is
proceeding with due diligence to cure such failure and such failure is
remedied not later than three hundred sixty (360) days after receipt by
Lessee of such written notice; or

               (d) any representation or warranty made by Lessee herein or
in the Participation Agreement or any document or certificate furnished by
Lessee in connection herewith or therewith or pursuant hereto or thereto
(except the representations and warranties set forth in the Tax Indemnity
Agreement and such documents or certificates as are furnished to the Owner
Participant solely in connection with matters dealt with in the Tax
Indemnity Agreement and for no other purpose and except for representations
or warranties contained in the Pass Through Trust Agreement, the
Underwriting Agreement or any document or instrument furnished pursuant to
either thereof) shall prove to have been incorrect in any material respect
at the time made, shall remain material at the time in question and such
incorrectness shall not have been cured (to the extent of the adverse
impact of such incorrectness on the interests of the Owner Participant,
Lessor or the Note Holders) within thirty (30) days after the receipt by
Lessee of a written notice from Lessor or the Indenture Trustee advising
Lessee of the existence of such incorrectness; or

               (e) the commencement of an involuntary case or other
proceeding in respect of Lessee in an involuntary case under the federal
bankruptcy laws, as now or hereafter constituted, or any other applicable
federal or state bankruptcy, insolvency or other similar law in the United
States or seeking the appointment of a receiver, liquidator, assignee,
custodian, trustee, sequestrator (or similar official) of Lessee or for all
or substantially all of its property, or seeking the winding-up or
liquidation of its affairs and the continuation of any such case or other
proceeding undismissed and unstayed for a period of ninety (90) consecutive
days or an order, judgment or decree shall be entered in any proceeding by
any court of competent jurisdiction appointing, without the consent of
Lessee, a receiver, trustee or liquidator of Lessee, or of any substantial
part of its property, or sequestering any substantial part of the property
of Lessee and any such order, judgment or decree or appointment or
sequestration shall be final or shall remain in force undismissed, unstayed
or unvacated for a period of ninety (90) days after the date of entry
thereof; or

               (f) the commencement by Lessee of a voluntary case under the
federal bankruptcy laws, as now constituted or hereafter amended, or any
other applicable federal or state bankruptcy, insolvency or other similar
law in the United States, or the consent by Lessee to the appointment of or
taking possession by a receiver, liquidator, assignee, trustee, custodian,
sequestrator (or other similar official) of Lessee or for all or
substantially all of its property, or the making by Lessee of any
assignment for the benefit of creditors, or Lessee shall take any corporate
action to authorize any of the foregoing; or

               (g) Lessee shall fail to carry and maintain on or with
respect to the Aircraft (or cause to be carried and maintained) insurance
required to be maintained in accordance with the provisions of Section 11
hereof;

provided, however, that, notwithstanding anything to the contrary contained
in Section 14(c) or (d) hereof, any failure of Lessee to perform or observe
any covenant, condition, agreement or any error in a representation or
warranty shall not constitute an Event of Default if such failure or error
is caused solely by reason of an event that constitutes an Event of Loss so
long as Lessee is continuing to comply with all of the terms of Section 10
hereof.

               SECTION 15. REMEDIES. Upon the occurrence of any Event of
Default and at any time thereafter so long as the same shall be continuing,
Lessor may, at its option, declare by written notice to Lessee this Lease
to be in default; and at any time thereafter, so long as any such
outstanding Events of Default shall not have been remedied, Lessor may do
one or more of the following with respect to all or any part of the
Airframe and any or all of the Engines as Lessor in its sole discretion
shall elect, to the extent permitted by, and subject to compliance with any
mandatory requirements of, applicable law then in effect; provided,
however, that during any period the Aircraft is subject to the Civil
Reserve Air Fleet Program in accordance with the provisions of Section 7(b)
hereof and in possession of the United States government or an agency or
instrumentality of the United States, Lessor shall not, on account of any
Event of Default, be entitled to do any of the following in such manner as
to limit Lessee's control under this Lease (or any Sublessee's control
under any Sublease) of any Airframe or any Engines installed thereon,
unless at least sixty (60) days (or such lesser period as may then be
applicable under the Air Mobility Command program of the United States
Government) written notice of default hereunder shall have been given by
Lessor by registered or certified mail to Lessee (and any Sublessee) with a
copy addressed to the Contracting Office Representative for the Air
Mobility Command of the United States Air Force under any contract with
Lessee (or any Sublessee) relating to the Aircraft:

               (a) upon the written demand of Lessor and at Lessee's
expense, cause Lessee to return promptly, and Lessee shall return promptly,
the Airframe or any Engine as Lessor may so demand to Lessor or its order
in the manner and condition required by, and otherwise in accordance with
all the provisions of, Section 5 as if such Airframe or Engine were being
returned at the end of the Term, or Lessor, at its option, may enter upon
the premises where all or any part of the Airframe or any Engine is located
and take immediate possession of and remove the same by summary proceedings
or otherwise (and/or, at Lessor's option, store the same at Lessee's
premises until disposal thereof by Lessor), all without liability accruing
to Lessor for or by reason of such entry or taking of possession or
removing whether for the restoration of damage to property caused by such
action or otherwise;

               (b) sell the Airframe and/or any Engine at public or private
sale, as Lessor may determine, or otherwise dispose of, hold, use, operate,
lease to others or keep idle the Aircraft as Lessor, in its sole
discretion, may determine, all free and clear of any rights of Lessee,
except as hereinafter set forth in this Section 15;

               (c) whether or not Lessor shall have exercised, or shall
thereafter at any time exercise, any of its rights under paragraph (a) or
paragraph (b) above with respect to the Airframe and/or any Engine, Lessor,
by written notice to Lessee specifying a payment date which shall be the
Lease Period Date not earlier than ten (10) days from the date of such
notice, may demand that Lessee pay to Lessor, and Lessee shall pay Lessor,
on the payment date so specified, as liquidated damages for loss of a
bargain and not as a penalty (in lieu of the installments of Basic Rent for
the Aircraft due for Lease Periods commencing on or after the Lease Period
Date specified as the payment date in such notice), any unpaid Basic Rent
due on Lease Period Dates prior to the payment date so specified
(including, without limitation, any adjustments to Basic Rent payable
pursuant to Section 3(c)) plus whichever of the following amounts Lessor,
in its sole discretion, shall specify in such notice (together with
interest, if any, on such amount at the Past Due Rate from such specified
payment date until the date of actual payment of such amount): (i) an
amount equal to the excess, if any, of the Termination Value for
the Aircraft, computed as of the Lease Period Date specified as the payment
date in such notice, over the aggregate fair market rental value (computed
as hereafter in this Section 15 provided) of such Aircraft for the
remainder of the Term, after discounting such aggregate fair market rental
value to present value as of the Lease Period Date specified as the payment
date in such notice at an annual rate equal to the Past Due Rate; or (ii)
an amount equal to the excess, if any, of the Termination Value for such
Aircraft, computed as of the Lease Period Date specified as the payment
date in such notice over the fair market sales value of such Aircraft
(computed as hereafter in this Section provided) as of the Lease Period
Date specified as the payment date in such notice;

               (d) in the event Lessor, pursuant to paragraph (b) above,
shall have sold the Airframe and/or any Engine, Lessor, in lieu of
exercising its rights under paragraph (c) above with respect to such
Aircraft, may, if it shall so elect, demand that Lessee pay Lessor, and
Lessee shall pay to Lessor, on the date of such sale, as liquidated damages
for loss of a bargain and not as a penalty (in lieu of the installments of
Basic Rent for the Aircraft due on or after such date), any unpaid Basic
Rent with respect to the Aircraft due prior to such date (including,
without limitation, any adjustments to Basic Rent payable pursuant to
Section 3(c)) plus the amount of any deficiency between the net proceeds of
such sale (after deduction of all reasonable costs of sale) and the
Termination Value of such Aircraft, computed as of the Termination Date on
or immediately following the date of such sale together with interest, if
any, on the amount of such deficiency, at the Past Due Rate, from the date
of such sale to the date of actual payment of such amount; and/or

               (e) Lessor may rescind this Lease as to the Aircraft, and/or
may exercise any other right or remedy which may be available to it under
applicable law or proceed by appropriate court action to enforce the terms
hereof or to recover damages for breach hereof.

               For the purposes of paragraph (c) above, the "fair market
rental value" or the "fair market sales value" of the Aircraft shall be the
rental value or sales value, as the case may be, which would be obtained in
an arm's-length transaction between an informed and willing lessee or
purchaser, as the case may be, under no compulsion to lease or purchase, as
the case may be, and an informed and willing lessor or seller in possession
under no compulsion to lease, sell, as the case may be, in each case based
upon the actual condition and location of the Aircraft, which value shall
be determined by mutual agreement or, in the absence of mutual written
agreement, pursuant to an appraisal prepared and delivered by a nationally
recognized firm of independent aircraft appraisers nominated by Lessor, and
Lessor shall immediately notify Lessee of such nomination. Unless Lessee
shall have objected in writing within ten (10) Business Days after its
receipt of Lessor's notice, Lessor's nomination shall be conclusive and
binding. If Lessee shall object, however, Lessor and Lessee shall endeavor,
within ten (10) Business Days after such objection is made, to select a
mutually acceptable appraiser; provided that, if Lessee shall not so
endeavor to make such selection, Lessor's nomination referred to in the
preceding sentence hereof shall be conclusive and binding. If Lessor and
Lessee fail to reach agreement (except for the reason referred to in the
proviso in the preceding sentence), or if any appraiser selected fails to
act for any reason, then the question shall be determined by an appraisal
(applying the definitions of "fair market rental value" and "fair market
sales value" as set forth above based upon the actual condition of the
Aircraft) mutually agreed to by two (2) recognized independent aircraft
appraisers, one of which appraisers shall be chosen by Lessor and one by
Lessee within five (5) Business Days after Lessor or Lessee shall have
received written notice from the other party of a demand that such an
appraisal be made, which notice shall specify the appraiser chosen by the
party giving the notice or, if such appraisers cannot agree on the amount
of such appraisal within twenty (20) Business Days after the end of such
five (5) Business Day period, each shall render its own appraisal and shall
by mutual consent choose another appraiser within five (5) Business Days
after the end of such twenty (20) day period. If, within such five (5) day
period, such two appraisers fail to appoint a third appraiser, then either
Lessor or Lessee, on behalf of both, may request such appointment by the
then President of the Association of the Bar of the City of New York (or
any successor organization thereto) or, in his absence, failure, refusal or
inability to act, then either Lessor or Lessee may apply to the American
Arbitration Association (or any successor organization thereto) in New
York, New York for the appointment of such third appraiser. The decision of
the third appraiser so appointed shall be given within twenty (20) Business
Days after the appointment of such third appraiser. As soon as the third
appraiser has delivered his appraisal, that appraisal shall be compared
with the appraisals given by the other two (2) appraisers. If the
determination of one appraiser is more disparate from the average of all
three determinations than each of the other two determinations, then the
determination of such appraiser shall be excluded, the remaining two
determinations shall be averaged and such average shall be final and
binding upon the parties hereto. If no determination is more disparate from
the average of all three determinations than each of the other
determinations, then such average shall be final and binding upon the
parties thereto. The cost of such appraisal or appointment shall be borne
by Lessee.

               In addition, Lessee shall be liable, except as otherwise
provided above and without duplication of amounts payable hereunder, for
any and all unpaid Rent due hereunder before, after or during the exercise
of any of the foregoing remedies and for all reasonable legal fees and
other costs and expenses (including fees of the appraisers hereinabove
referred to) incurred by Lessor, the Indenture Trustee, the Loan
Participants and the Owner Participant in connection with the return of the
Airframe or any Engine in accordance with the terms of Section 5 or in
placing such Airframe or Engine in the condition and airworthiness required
by such Section.

               At any sale of the Aircraft or any part thereof pursuant to
this Section 15, Lessor (or the Indenture Trustee, any Loan Participant or
the Owner Participant) or Lessee may bid for and purchase such property.
Lessor agrees to give Lessee at least fifteen (15) days prior written
notice of the date fixed for any public sale of the Airframe or any Engine
or of the date on or after which will occur the execution of any contract
providing for any private sale and any such public sale shall be conducted
in general so as to afford Lessee (and any Sublessee) a reasonable
opportunity to bid. Except as otherwise expressly provided above, no remedy
referred to in this Section 15 is intended to be exclusive, but each shall
be cumulative and in addition to any other remedy referred to above or
otherwise available to Lessor at law or in equity; and the exercise or
beginning of exercise by Lessor of any one or more of such remedies shall
not preclude the simultaneous or later exercise by Lessor of any or all of
such other remedies. No waiver by Lessor of any Event of Default shall in
any way be, or be construed to be, a waiver of any future or subsequent
Event of Default.

               SECTION 16. LESSEE'S COOPERATION CONCERNING CERTAIN MATTERS;
DELIVERY OF FINANCIAL STATEMENTS. Forthwith upon the execution and delivery
of each Lease Supplement and Trust Supplement from time to time required by
the terms hereof and upon the execution and delivery of any amendment to
this Lease, to the Trust Indenture or to the Trust Agreement, Lessee will
cause such Lease Supplement, Trust Supplement (and, in the case of the
initial Lease Supplement and Trust Supplement, this Lease, the Trust
Agreement and the Trust Indenture as well) or amendment to be duly filed
and recorded, and maintained of record, in accordance with the applicable
laws of the government of registry of the Aircraft. In addition, Lessee
will promptly and duly execute and deliver to Lessor such further documents
and take such further action as Lessor or the Indenture Trustee may from
time to time reasonably request in order more effectively to carry out the
intent and purpose of this Lease and to establish and protect the rights
and remedies created or intended to be created in favor of Lessor and the
Indenture Trustee hereunder, including, without limitation, if requested by
Lessor or the Indenture Trustee, at the expense of Lessee, the execution
and delivery of supplements or amendments hereto or to the Trust Indenture,
each in recordable form, subjecting to this Lease and the Trust Indenture,
any airframe or engine substituted for the Airframe or any Engine pursuant
to the terms thereof and the recording or filing of counterparts
thereof, in accordance with the laws of such jurisdictions as Lessor or the
Indenture Trustee may from time to time deem advisable. Lessee agrees to
furnish to Lessor and the Indenture Trustee promptly after execution and
delivery of any supplement and amendment hereto and promptly after the
execution and delivery of any supplement and amendment to the Trust
Indenture (except for any such supplement or amendment which does not
require or receive the approval of Lessee pursuant to the Operative
Documents and is not required pursuant to the terms of the Operative
Documents), an opinion of counsel (which may be Lessee's General Counsel,
Deputy General Counsel, Associate General Counsel or Assistant General
Counsel) reasonably satisfactory to Lessor and the Indenture Trustee as to
the due recording or filing of such supplement or amendment. Lessee will
deliver to Lessor, the Owner Participant and the Indenture Trustee (a)
within sixty (60) days after the end of each of the first three quarterly
periods of each fiscal year of Lessee, the publicly filed Form 10-Q report
of Lessee; and (b) within one hundred twenty (120) days after the close of
such fiscal year, the publicly filed annual report and Form 10-K report of
Lessee.

               SECTION 17. NOTICES. All notices required under the terms
and provisions hereof shall be by telecopier or other telecommunication
means (with such telecopy or other telecommunication means to be confirmed
in writing), or if such notice is impracticable, by registered, first-class
airmail, with postage prepaid, or by personal delivery of written notice
and any such notice shall become effective when received, addressed:

               (a)    if to Lessee, for U.S. mail at 2345 Crystal Drive,
Arlington, Virginia 22227, and for overnight courier at 2345 Crystal Drive,
Arlington, Virginia 22227, Attention: Treasurer (Telecopy No. (703)
872-5936), or to such other address or telecopy number as Lessee shall from
time to time designate in writing to Lessor,

               (b)    if to Lessor, at 79 South Main Street, 3rd Floor,
Salt Lake City, Utah 84111, Attention: Corporate Trust Department (Telecopy
No. (801) 246-5053), or to such other address or telecopy number as Lessor
shall from time to time designate in writing to Lessee, and

               (c) if to a Loan Participant, the Indenture Trustee or the
Owner Participant, addressed to such Loan Participant, the Indenture
Trustee or the Owner Participant at such address or telecopy number as such
Loan Participant, the Indenture Trustee or the Owner Participant shall have
furnished by notice to Lessor and to Lessee, and, until an address is so
furnished, addressed to such Loan Participant, the Indenture
Trustee or the Owner Participant at its address or telecopy number set
forth in Schedule I to the Participation Agreement.

               SECTION 18. NO SET-OFF, COUNTERCLAIM, ETC. All Rent shall be
paid by Lessee to Lessor in funds of the type specified in Section 3(e).
Except as expressly provided herein, Lessee's obligation to pay all Rent
payable hereunder shall be absolute and unconditional and shall not be
affected by any circumstance, including, without limitation, (i) any
set-off, counterclaim, recoupment, defense or other right which Lessee may
have against Lessor, in its individual capacity or as Owner Trustee under
the Trust Agreement, the Indenture Trustee (in its individual capacity or
as Indenture Trustee), any Loan Participant, the Owner Participant, or
anyone else for any reason whatsoever (whether in connection with the
transactions contemplated hereby or any other transactions), including,
without limitation, any breach by Lessor or the Owner Participant of their
respective warranties, agreements or covenants contained in any of the
Operative Documents, (ii) any defect in the title, registration,
airworthiness, condition, design, operation, or fitness for use of, or any
damage to or loss or destruction of, the Aircraft, or any interruption or
cessation in or prohibition of the use or possession thereof by Lessee (or
any Sublessee) for any reason whatsoever, including, without limitation,
any such interruption, cessation or prohibition resulting from the act of
any government authority, (iii) any insolvency, bankruptcy, reorganization
or similar case or proceedings by or against Lessee (or any Sublessee) or
any other Person, or (iv) any other circumstance, happening, or event
whatsoever, whether or not unforeseen or similar to any of the foregoing;
provided, however, that notwithstanding the foregoing, Lessee shall be
entitled to offset from any payment due to the Owner Participant the cost
incurred by Lessee to discharge Lessor Liens relating to the Owner
Participant. If for any reason whatsoever this Lease shall be terminated in
whole or in part by operation of law or otherwise except as specifically
provided herein, Lessee nonetheless agrees without limitation of the other
rights or remedies of Lessor hereunder to pay to Lessor an amount equal to
each Rent payment at the time such payment would have become due and
payable in accordance with the terms hereof had this Lease not been
terminated in whole or in part. Lessee hereby waives, to the extent
permitted by applicable law, any and all rights which it may now have or
which at any time hereafter may be conferred upon it, by statute or
otherwise, to terminate, cancel, quit or surrender this Lease except in
accordance with the express terms hereof.



               SECTION 19.  RENEWAL OPTIONS; PURCHASE OPTIONS; VALUATION.
                            --------------------------------------------

               (a)    Renewal Options.
                      ---------------

                      (1) Fixed Renewal Term. Not more than 365 days and
        not less than one hundred twenty (120) days, before the end of the
        Basic Term or any Fixed Renewal Term (as hereinafter defined),
        Lessee may deliver to Lessor a written notice irrevocably electing
        to renew this Lease for a term having a duration and at a Basic
        Rent as determined below (any such renewal term, a "Fixed Renewal
        Term"). The duration of any Fixed Renewal Term shall be a period
        specified by Lessee before the end of the Basic Term which is (i)
        not less than one year (provided any such period shall be in six
        (6) month increments), (ii) not more than the longest period of
        time which would cause the Term, after giving effect to such Fixed
        Renewal Term, to be equal to 75% of the total useful life of the
        aircraft as determined by the Delivery Date appraisal. Each semi-
        annual installment of Basic Rent during the Fixed Renewal Term
        shall be equal to the lesser of (A) the fair market rental value of
        the Aircraft or (B) (I) one-half of the average annual Basic Rent
        during the Basic Term divided by (II) two (2).

                      (2) Fair Market Renewal Term. Lessee shall have the
        right to renew this Lease for additional periods of one (1) year or
        more (provided any such period shall be on six (6) month
        increments) commencing at the end of the Basic Term or the Fixed
        Renewal Term for a Basic Rent equal to the fair market rental value
        of the Aircraft for such period (any such renewal term, a "Fair
        Market Renewal Term"). Each such option to renew shall be exercised
        by Lessee providing irrevocable notice at least one hundred twenty
        (120) days prior to the commencement of such Fair Market Renewal
        Term.

                      (3) Waiver. If no written notice is delivered by
        Lessee to Lessor pursuant to Section 19(a)(1) or (a)(2) on or
        before the day specified therefor, Lessee shall be deemed to have
        waived any right to renew this Lease.

                      (4)   Conditions Precedent, Payment of Basic Rent.  At
                            -------------------------------------------
        the end of the Basic Term or any Renewal Term, if Lessee has elected
        to renew this Lease as aforesaid, (i) this Lease shall continue in
        full force and effect during the Renewal Term and (ii) Basic Rent
        for such Renewal Term shall be payable in semi-annual
        installments in arrears, each such installment being due and
        payable on each Lease Period Date occurring during the Renewal
        Term, commencing with the Lease Period Date immediately following
        the commencement of the Renewal Term, provided that Basic Rent
        for such Renewal Term shall be payable at such other frequency of
        payment consistent with the length of the Renewal Term as Lessor
        may reasonably designate in the event that such period is not
        divisible into whole semi-annual periods.

                      (5) Termination Value. The amounts which are payable
        during any Renewal Term in respect of Termination Value with
        respect to the Aircraft shall be determined on the basis of the
        fair market sales value of the Aircraft as of the commencement of
        such Renewal Term, amortized on a straight-line basis over such
        Renewal Term to the projected fair market sales value of the
        Aircraft as of the expiration of such Renewal Term, as such fair
        market sales value in each case is determined prior to the
        commencement of such Renewal Term. In determining fair market sales
        value for purposes of calculating Termination Value for any Renewal
        Term effect shall be given to the encumbrance on the Aircraft of
        any Fixed Renewal Term available or in force.

               (b) Purchase Options. Lessee shall have the option, (i) upon
at least thirty (30) days irrevocable prior written notice to Lessor prior
to the EBO Date with respect to the purchase option set forth in clause (i)
and (ii) upon at least one hundred twenty (120) days irrevocable prior
written notice to Lessor prior to the relevant purchase date (each a
"Purchase Option Date") with respect to the purchase options set forth in
clauses (ii) and (iii), to terminate this Lease and to purchase the
Aircraft:

                      (1) on the EBO Date, for a purchase price equal to
        the EBO Amount set forth on Exhibit D, it being understood that if
        such amount is to be paid in installments, Lessee will, upon
        payment of the first installment of the EBO Amount, on the EBO
        date, receive title to the Aircraft free and clear of all liens
        (other than the Lien of the Indenture if Lessee has elected to
        assume the Equipment Notes in accordance with Section 7(u) of the
        Participation Agreement);

                      (2) on the last Business Day of the Basic Term for a
        purchase price equal to the fair market sales value of the Aircraft
        on such date, provided, however, that in no event shall such
        purchase price exceed 50% of Lessor's Cost;

                      (3) on the last Business Day of any Renewal Term for
        a purchase price equal to the fair market sales value of the
        Aircraft on such date.

               Notwithstanding the foregoing but subject to the last
sentence of this paragraph, the purchase price on any Purchase Option Date
shall be sufficient, together with all other amounts payable simultaneously
by Lessee, to pay in full the payments then required to be made on account
of the principal amount of and accrued and unpaid interest on the Equipment
Notes then outstanding. Upon payment to Lessor in immediately available
funds in Dollars of the full amount of the purchase price and payment of
any other amounts then due hereunder (including all Rent and all reasonable
costs or expenses of the Owner Participant in connection with such
purchase), Lessor will transfer to Lessee, without recourse or warranty
(except as to the absences of Lessor Liens), all of Lessor's right, title
and interest in and to the Aircraft. Notwithstanding the foregoing, Lessee
may, in accordance with Section 7(u) of the Participation Agreement, assume
the principal amount of the Equipment Notes then outstanding on any
applicable Purchase Option Date in which event Lessee shall receive a
credit against the purchase price otherwise payable pursuant to the
preceding two sentences in an amount equal to the principal amount so
assumed.

               (c) Valuation. At any time not earlier than three hundred
sixty-five (365) days prior to the date on which Lessee may purchase the
Aircraft pursuant to Section 19(b)(2) or (b)(3) hereof or renew this Lease
pursuant to Section 19(a)(1) or (a)(2) hereof, Lessee may deliver to Lessor
a revocable notice of its intent to exercise its renewal option or purchase
option. For all purposes of this Section 19 and Section 20, including the
appraisal referred to in this Section 19(c), in determining "fair market
rental value" or "fair market sales value", the Aircraft shall be valued
(i) as if in the condition and otherwise in compliance with the terms of
Section 5 upon a return of the Aircraft to Lessor and as if it had been
maintained at all times as required in accordance with Section 7(a)(i)
during periods when no Sublease was in effect, (ii) on the basis of the
value which would obtain in an arm's-length transaction between an informed
and willing buyer-user or lessee (other than a lessee or an Affiliate of a
lessee currently in possession or a used equipment scrap dealer) under no
compulsion to buy or lease and an informed and willing seller or lessor
unaffiliated with such buyer-user or lessee and under no compulsion to sell
or lease and disregarding the purchase and renewal options of the lessee
provided in this Lease and (iii) in the case of such valuation for
determining "fair market rental value", assuming such lessee would have
substantially the same obligations during the Fair Market Renewal Term as
provided hereunder including without limitation the obligations of Lessee
to carry and maintain the insurance required by Section 11 hereof and to
make certain payments with reference to Termination Value during the
applicable Fair Market Renewal Term. Upon receipt of such notice Lessor and
Lessee shall confer in good faith with a view to reaching agreement on the
"fair market rental value" or "fair market sales value" of the Aircraft. If
the parties have not so agreed within two hundred seventy (270) days prior
to the end of the Basic Term or the Renewal Term in question, then the
question shall be determined by an appraisal mutually agreed to by two
recognized independent aircraft appraisers, one of which appraisers shall
be chosen by Lessor and one by Lessee within five (5) Business Days after
Lessor or Lessee shall have received written notice from the other party of
a demand that such an appraisal be made, which notice shall specify the
appraiser chosen by the party giving the notice or, if such appraisers
cannot agree on the amount of such appraisal within twenty (20) Business
Days after the end of such five (5) Business Day period, each shall render
its own appraisal and shall by mutual consent choose another appraiser
within five (5) Business Days after the end of such twenty (20) Business
Day period. If, within such five (5) Business Day period, such two
appraisers fail to appoint a third appraiser, then either Lessor or Lessee,
on behalf of both, may request such appointment by the then President of
the Association of the Bar of the City of New York (or any successor
organization thereto) or, in his absence, failure, refusal or inability to
act, then either Lessor or Lessee may apply to the American Arbitration
Association (or any successor organization thereto) in New York, New York
for the appointment of such third appraiser. The decision of the third
appraiser so appointed shall be given within ten (10) Business Days after
the appointment of such third appraiser. As soon as the third appraiser has
delivered his appraisal, that appraisal shall be compared with the
appraisals given by the other two appraisers. If the determination of one
appraiser is more disparate from the average of all three determinations
than each of the other two determinations, then the determination of such
appraiser shall be excluded, the remaining two determinations shall be
averaged and such average shall be final and binding upon the parties
hereto. If no determination is more disparate from the average of all three
determinations than each of the other determinations, then such average
shall be final and binding upon the parties thereto. Lessee and Lessor
shall share equally all expenses relating to such appraisal procedure
provided if Lessee elects not to renew this Lease or purchase the Aircraft
following such appraisal, Lessee shall pay all expenses of such appraisal.

               SECTION 20. BURDENSOME PURCHASE OPTION. If a Burdensome
Termination Event shall have occurred, then on any Lease Period Date
occurring after the expiration of the Depreciation Period, Lessee shall
have the option, upon at least one hundred twenty (120) days revocable
prior notice to Lessor and, if any Equipment Notes are then outstanding,
the Indenture Trustee, to purchase the Aircraft on such date for a purchase
price equal to the higher of the Termination Value as of such date or the
fair market sales value of the aircraft (determined as set forth in clause
(c) above and excluding the value of any Significant Expenditure) (such
price, the "Burdensome Buyout Price"). In addition, if on such date there
shall be any Equipment Notes outstanding, Lessee shall have the option to
assume, pursuant to Section 7(u) of the Participation Agreement and Section
2.13 of the Trust Indenture, all of the obligations of Lessor under the
Trust Indenture. If such assumption is made, Lessee shall pay Lessor a
purchase price equal to (I) the Burdensome Buyout Price minus (II) an
amount equal to principal of, and accrued but unpaid interest on, any
Equipment Notes that are outstanding on such date. Upon such payment in
full and payment of any other amounts then due hereunder (including costs
or expenses of the Owner Participant in connection with such purchase, any
installments of Basic Rent due prior to such date and, if Basic Rent is
payable in arrears on such date as indicated on Exhibit B, on such date
(but not any installment of Basic Rent due on such date if Basic Rent is
payable in advance on such date), and all unpaid Supplemental Rent due on
or prior to such date), Lessor will transfer to Lessee, without recourse or
warranty (except as to the absence of Lessor Liens), all of Lessor's right,
title and interest in and to the Aircraft and under the Trust Indenture
and, unless there shall be any Equipment Notes outstanding after such
payment, exercise such rights as it has to cause the Aircraft to be
released from the Lien of the Trust Indenture.

               SECTION 21. SECURITY FOR LESSOR'S OBLIGATION TO HOLDERS OF
EQUIPMENT NOTES. In order to secure the indebtedness evidenced by the
Equipment Notes, Lessor has agreed in the Trust Indenture, among other
things, to assign to the Indenture Trustee this Lease, the Lease
Supplements and any amendments to this Lease and to mortgage its interest
in the Aircraft in favor of the Indenture Trustee, subject to the
reservations and conditions therein set forth. To the extent, if any, that
this Lease, the Lease Supplements and any amendments to this Lease
constitute chattel paper (as such term is defined in the Uniform Commercial
Code as in effect in any applicable jurisdiction), no security interest in
this Lease, the Lease Supplements and any amendments to this Lease may be
created through the transfer or possession of any counterpart other than
the original counterpart, which shall be identified as the counterpart
containing the receipt therefor executed by the Indenture Trustee on the
signature page thereof. Lessee hereby accepts and consents to the
assignment of all Lessor's right, title and interest in and to this Lease
pursuant to the terms of the Trust Indenture. Subject to Section 3(e)
hereof, Lessee agrees to pay directly to the Indenture Trustee (or, after
receipt by Lessee of notice from the Indenture Trustee of the discharge of
the Trust Indenture, to Lessor), all amounts of Rent due or to become due
hereunder and assigned to the Indenture Trustee and Lessee agrees that the
Indenture Trustee's right to such payments hereunder shall be absolute and
unconditional and shall not be affected by any circumstance, including,
without limitation, the circumstances set forth in clauses (i) through (iv)
of Section 18 hereof. Notwithstanding the foregoing assignment of this
Lease, the obligations of Lessor to Lessee to perform the terms and
conditions of this Lease shall remain in full force and effect.

               SECTION 22. LESSOR'S RIGHT TO PERFORM FOR LESSEE. If Lessee
fails to make any payment of Rent required to be made by it hereunder or
fails to perform or comply with any of its agreements contained herein,
then (but in each case, except in the case of failure to pay Rent or in the
case of failure to maintain insurance as required hereunder, no earlier
than the fifteenth day after the occurrence of such failure, whether or not
it shall yet constitute an Event of Default hereunder) Lessor may itself
make such payment or perform or comply with such agreement but shall not be
obligated hereunder to do so, and the amount of such payment and the amount
of the reasonable expenses of Lessor incurred in connection with such
payment or the performance of or compliance with such agreement, as the
case may be, together with interest thereon at the Past Due Rate, shall be
deemed Supplemental Rent, payable by Lessee upon demand.

               SECTION 23.  INVESTMENT OF SECURITY FUNDS; LIABILITY OF LESSOR
LIMITED.

               (a) Investment of Security Funds. Any moneys held by Lessor
as security hereunder for future payments to Lessee at a time when there is
not continuing an Event of Default shall, until paid to Lessee, be invested
by Lessor or, if the Trust Indenture shall not have been discharged, by the
Indenture Trustee, as the case may be, as Lessee may from time to time
direct in writing (and in absence of a written direction by Lessee, there
shall be no obligation to invest such moneys) in Cash Equivalents. There
shall be promptly remitted to Lessee or its order (but no more frequently
than monthly) any gain (including interest received) realized as a result
of any such investment (net of any fees, commissions and other expenses, if
any, incurred in connection with such investment) unless an Event of
Default shall have occurred and be continuing. Lessee shall be responsible
for any net loss realized as a result of any such investment and shall
reimburse Lessor (or the Indenture Trustee, as the case may be) therefor on
demand.

               (b) Liability of Lessor Limited. It is expressly agreed and
understood that all representations, warranties and undertakings of Lessor
hereunder shall be binding upon Lessor only in its capacity as trustee
under the Trust Agreement, and the institution acting as Lessor shall not
be liable in its individual capacity for any breach thereof except for its
gross negligence or willful misconduct or for breach of its covenants,
representations and warranties contained herein, to the extent covenanted
or made in its individual capacity.

               SECTION 24. JURISDICTION. Lessor and Lessee each hereby
irrevocably submits itself to the non-exclusive jurisdiction of the United
States District Court for the Southern District of New York and to the
non-exclusive jurisdiction of the Supreme Court of the State of New York,
New York County, for the purposes of any suit, action or other proceeding
arising out of this Lease, the subject matter hereof or any of the
transactions contemplated hereby brought by Lessor, Lessee, the Indenture
Trustee, the Loan Participants or the Owner Participant or their successors
or assigns.

               SECTION 25. MISCELLANEOUS. Any provision of this Lease 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, and
any such prohibition or unenforceability in any jurisdiction shall not
invalidate or render unenforceable such provision in any other
jurisdiction. No term or provision of this Lease may be changed, waived,
discharged or terminated orally, but only by an instrument in writing
signed by Lessor, Lessee and any assignee of Lessor's rights hereunder.
This Lease shall constitute an agreement of lease, and nothing contained
herein shall be construed as conveying to Lessee any right, title or
interest in the Aircraft except as a lessee only. Neither Lessee nor any
affiliate of Lessee will file any tax returns in a manner inconsistent with
the foregoing fact or with Lessor's ownership of the Aircraft. The section
and paragraph headings in this Lease and the table of contents are for
convenience of reference only and shall not modify, define, expand or limit
any of the terms or provisions hereof and all references herein to numbered
sections, unless otherwise indicated, are to sections of this Lease. THIS
LEASE HAS BEEN DELIVERED IN THE STATE OF NEW YORK AND SHALL IN ALL RESPECTS
BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF
NEW YORK, INCLUDING ALL MATTERS OF CONSTRUCTION, VALIDITY AND PERFORMANCE.
This Lease 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 26. SUCCESSOR TRUSTEE. Lessee agrees that in the
case of the appointment of any successor Owner Trustee pursuant to the
terms of the Trust Agreement, such successor Owner Trustee shall, upon
written notice by such successor Owner Trustee, succeed to all the rights,
powers and title of Lessor hereunder and shall be deemed to be Lessor and
the owner of the Aircraft for all purposes hereof without the necessity of
any consent or approval by Lessee (subject to Section 9 of the
Participation Agreement) and without in any way altering the terms of this
Lease or Lessee's obligations hereunder. One such appointment and
designation of a successor Owner Trustee shall not exhaust the right to
appoint and designate further successor Owner Trustees pursuant to the
Trust Agreement, but such right may be exercised repeatedly as long as this
Lease shall be in effect.

               SECTION 27.  LEASE FOR U.S. FEDERAL INCOME TAX LAW PURPOSES;
                            -----------------------------------------------
SECTION 1110 OF BANKRUPTCY CODE
- -------------------------------

               (a)    Lease for Federal Income Tax Law Purposes.  It is the
intent of the parties to this Agreement that this Lease is a true lease for
U.S. Federal income tax purposes.

               (b) Section 1110 of Bankruptcy Code. It is the intention of
each of Lessee and Lessor that Lessor (and the Indenture Trustee as secured
party and as assignee of Lessor under the Trust Indenture) shall be
entitled to the benefits of Section 1110 of the Bankruptcy Code with
respect to the right to take possession of the Aircraft, Airframe, Engines
and Parts as provided in this Lease.


               IN WITNESS WHEREOF, Lessor and Lessee have each caused this
Lease to be duly executed as of the day and year first above written.

                                    herein, but solely as Owner Trustee,

As set forth in Section 21 of the Lease (as defined below), Lessor has
assigned to the Indenture Trustee (as defined herein) certain of its right,
title and interest in and to the Lease and this Lease Supplement. To the
extent, if any, that this Lease Supplement constitutes chattel paper (as
such term is defined in the Uniform Commercial Code as in effect in any
applicable jurisdiction) no security interest in this Lease Supplement may
be created through the transfer or possession of any counterpart other than
the original executed counterpart, which shall be identified as the
counterpart containing the receipt therefor executed by the Indenture
Trustee on the signature page thereof.

                                                                     EXHIBIT A

               The portion of this Exhibit appearing below this will be
intentionally deleted from the FAA filing counterpart as the parties hereto
deem it to contain confidential information.

               Any recalculation of Basic Rent, Termination Value
percentages and EBO Amount pursuant to the Lease shall be determined by the
Owner Participant, and shall maintain the Owner Participant's Net Economic
Return except as assumptions have been modified pursuant to Section 3 of
the Lease or pursuant to the Tax Indemnity Agreement or the Participation
Agreement, as the case may be; provided, however, that Lessee may request
(A) Lessee's independent public accountants to verify such calculations but
without any requirement that the Owner Participant disclose to such Persons
the methodology and assumptions and (B) if Lessee believes that such
calculations by the Owner Participant are in error then a nationally
recognized firm of accountants selected by the Owner Participant and
reasonably acceptable to Lessee shall be permitted to verify such
calculations and the Owner Participant will make available to such firm
(subject to the execution by such firm of a confidentiality agreement
reasonably acceptable to the Owner Participant) the methodology and
assumptions and any changes made therein pursuant to Section 3 of the
Lease. In the event of a verification under clause (B) of the first
sentence of this paragraph the determination by such firm of accountants
shall be final. Lessee will pay the reasonable costs and expenses of the
verification under clause (B) of the first sentence of this paragraph
unless an error adverse to Lessee is established by such firm, and if as a
result of such verification process the Basic Rent is adjusted and such
adjustment causes the Net Present Value of Rents to decline by 10 (ten) or
more basis points or causes a material reduction in Termination Value, EBO
Amount or any indemnity payment (in which event the Owner Participant shall
pay the reasonable costs and expenses of such verification process). Such
recalculated Basic Rent, Termination Value percentages and EBO amounts
shall be set forth in a Lease Supplement or an amendment to the Lease.

               "Net Economic Return" means the Owner Participant's
after-tax yield and aggregate after-tax cash flow utilizing the multiple
investment sinking fund method of analysis, computed on the basis of the
same methodology and assumptions as were utilized by the Owner Participant
in determining Basic Rent, Termination Value percentages and EBO Amount as
of the Delivery Date.

                             RETURN CONDITIONS

        The portion of this Exhibit appearing below this text will be
intentionally deleted from the FAA filing counterpart as the parties hereto
deem it to contain confidential information.

               (a) Condition Upon Return. Unless purchased by Lessee
pursuant to Section 19 or 20 hereof, upon the termination of this Lease at
the end of the Basic Term or any Renewal Term or pursuant to Sections 9(b)
or 15, unless Lessor has requested that Lessee return the Aircraft to a
storage location pursuant to Section 5(b) (in which case the storage
location provided in said Section 5(b) shall be deemed to be the return
location), Lessee will return the Airframe to Lessor at one of Lessee's
principal maintenance bases located in one of the forty-eight contiguous
states of the United States chosen by Lessee, and Lessee will give Lessor
at least ten (10) days prior written notice of the place of such return. At
the time of such return, (i) Lessee will, at its own cost and expense,
unless otherwise requested by Lessor to retain the existing registration of
the Aircraft at least ninety (90) days prior to the date of return
hereunder, cause the Aircraft, if it is not then so registered, to be
registered under the laws of the United States with the Federal Aviation
Administration in the name of the Lessor or its designee, provided that
Lessee shall be relieved of its obligations under this sentence if such
registration is prohibited by reason of the failure of Lessor, Owner
Participant or Lessor's designee to be eligible on such date to own an
aircraft registered with the Federal Aviation Administration and (ii) the
Airframe will be fully equipped with the Engines (or Acceptable Alternate
Engines) installed thereon. Also, at the time of such return, Lessor shall
have good title to such Airframe and Engines or Acceptable Alternate
Engines, and such Airframe and Engine or Acceptable Alternate Engines (A)
shall be certified (or, if not then registered under the Transportation
Code by reason of the proviso of clause (i) in the preceding sentence or
because Lessor has so requested that the Aircraft not be so registered,
shall hold a valid certificate of airworthiness issued by the country of
registry and be eligible for certification by the Federal Aviation
Administration) as an airworthy aircraft by the Federal Aviation
Administration, (B) shall be free and clear of all Liens (other than Lessor
Liens, Indenture Trustee's Liens and Loan Participant Liens) and rights of
third parties under pooling, interchange, overhaul, repair or other similar
agreements or arrangements, (C) shall be in a regular passenger
configuration, and in as good a condition as when delivered by Seller to
Lessee, ordinary wear and tear excepted, and otherwise in the condition
required to be maintained under Lessee's FAA-approved maintenance plan
(notwithstanding any Sublease theretofore in effect), (D) in the event that
Lessee (or any Sublessee then in possession of the Aircraft) shall not then
be using a continuous maintenance program with respect to the Airframe
immediately prior to such return but instead shall have been using a block
overhaul program with respect to the Airframe, then (i) such block overhaul
program shall have been approved by the government of registry of the
Aircraft and (ii) the Airframe shall have remaining until the next
scheduled block overhaul at least 25% of the allowable hours between block
overhauls permitted under the block overhaul program then used by Lessee or
such Sublessee, (E) on average, the Engines or Acceptable Alternate Engines
shall not have been operated since the last engine shop visit more than 75%
of the time represented by Lessee's average on-wing hang time as then
applicable to mature engines employed on A330-___ aircraft in Lessee's
fleet (based on a three (3) year average), (F) shall have all Lessee's and
any Sublessee's exterior marking removed or painted over with areas thereof
refinished to match adjacent areas and (G) shall be in a state of
cleanliness suitable under Lessee's normal service standards for operation
in Lessee's revenue passenger service and in all such cases the Aircraft
shall not have been discriminated against whether by reason of its leased
status or otherwise in maintenance, use, operation or in any other manner
whatsoever.

               If clause (D) of the first paragraph of this subsection (a)
shall be applicable but the Airframe does not meet the conditions specified
in said clause (D), Lessee shall pay or cause to be paid to Lessor,
concurrently with the return thereof, a Dollar amount computed by
multiplying (i) 110% of the direct cost to Lessee (based upon the direct
cost to Lessee for similar aircraft in the fleet of Lessee) during the
preceding 12 months of performing an airframe block overhaul of the type
referred to in such clause (D) by (ii) a fraction of which (x) the
numerator shall be the excess of 25% of the hours of operation allowable
between such block overhauls over the actual number of hours of operation
remaining on the Airframe to the next such block overhaul and (y) the
denominator shall be the number of hours of operation allowable between
such block overhauls in accordance with such block overhaul program.

               If the Engines (or Acceptable Alternate Engines) do not meet
the conditions specified in clause (E) of the first paragraph of this
subsection (a), Lessee shall pay or cause to be paid to Lessor,
concurrently with the return thereof, a Dollar amount computed by
multiplying (i) two (2) times (ii) 110% of the direct cost to Lessee
(based upon the direct cost to Lessee for similar aircraft in the fleet of
Lessee) during the preceding 12 months of performing for an engine of the
same model as the Engines (or Acceptable Alternate Engines) the scheduled
engine heavy maintenance under the maintenance program then used by Lessee
for engines of the same model as the Engines (or Acceptable Alternate
Engines) (such applicable amount, the "HEM Value") times (iii)25%, and
subtracting from such product of clauses (i), (ii) and (iii), the value (as
calculated in accordance with the following sentence) of the aggregate of
the amount of time remaining to the next scheduled engine shop visit
(determined by using Lessee's average on-wing hang time as then applicable
to a mature engine of the type used on an A330-___ type aircraft (based on
a three (3) year average)) for the Engines or Acceptable Alternate Engines.
The value of the time to the next scheduled shop visit for any Engine or
Acceptable Alternate Engine shall be calculated by multiplying (i) a
fraction of which (x) the numerator shall be the amount of time remaining
until the next scheduled shop visit for such Engine or Acceptable Alternate
Engine and (y) the denominator shall be the average on-wing hang time for
such Engine or Acceptable Alternate Engine determined in accordance with
the preceding sentence by (ii) HEM Value.

               (b) Return of the Engines. In the event that an Acceptable
Alternate Engine shall be delivered with the returned Airframe as set forth
in subsection (a) of this Exhibit G, Lessee, concurrently with such
delivery, will, at no cost to Lessor, furnish, or cause to be furnished, to
Lessor a full warranty (as to title) bill of sale with respect to each such
Acceptable Alternate Engine, in form and substance satisfactory to Lessor
(together with an opinion of counsel (which may be Lessee's General
Counsel, Deputy General Counsel, Associate General Counsel or Assistant
General Counsel) to the effect that such full warranty bill of sale has
been duly authorized and delivered and is enforceable in accordance with
its terms and that each such Acceptable Alternate Engine is free and clear
of all Liens other than Lessor Liens, Loan Participant Liens and Indenture
Trustee Liens), against receipt from Lessor of a bill of sale or evidencing
the transfer, without recourse or warranty (except as to the absence of
Lessor Liens), by Lessor to Lessee or its designee of all of Lessor's
right, title and interest in and to any Engine not installed on the
Airframe at the time of the return of the Airframe.

               (c) Fuel and Manuals. Upon the return of the Airframe upon
any termination of this Lease in accordance with subsection (a) of this
Exhibit G, (i) Lessor shall pay to Lessee, the amount of Lessee's cost for
any fuel or oil contained in the fuel or oil tanks of such Airframe and
(ii) Lessee shall deliver or cause to be delivered to Lessor all logs,
manuals and data and inspection, modification and overhaul records required
to be maintained under the provisions of the Lease.

        The portion of this Exhibit appearing below this text will be
intentionally deleted from the FAA filing counterpart as the parties hereto
deem it to contain confidential information.

               (a) Public Liability and Property Damage Insurance. (1)
Except as provided in clause (2) of this subsection (a), and subject to
self-insurance to the extent permitted by subsection (d) of this Exhibit H,
Lessee will carry or cause to be carried with respect to the Aircraft at
its or any Sublessee's expense (i) comprehensive airline liability
(including, without limitation, passenger, contractual, bodily injury and
property damage liability) insurance (exclusive of manufacturer's product
liability insurance) and (ii) cargo liability insurance, (A) in an amount
not less than the greater of (x) the amounts of comprehensive airline
liability insurance from time to time applicable to aircraft owned or
leased, and operated by Lessee (or, if a Sublease is then in effect, by
Sublessee) of the same type as the Aircraft and (y) $300 million per
occurrence, (B) of the type and covering the same risks as from time to
time applicable to aircraft owned or leased and operated by Lessee of the
same type as the Aircraft, and (C) which is maintained in effect with
insurers of nationally or internationally recognized reputation and
responsibility; provided, however, that Lessee need not maintain such cargo
liability insurance, or may maintain such cargo liability insurance in an
amount less than $300 million per occurrence, so long as the amount of
cargo liability insurance, if any, maintained with respect to the Aircraft
is not less than the cargo liability insurance, if any, maintained for
other Airbus Model A330 aircraft owned or leased and operated by Lessee.

               (2) During any period that the Airframe or an Engine, as the
case may be, is on the ground and not in operation, Lessee may carry or
cause to be carried as to such non-operating property, in lieu of the
insurance required by clause (1) above, and subject to the self-insurance
to the extent permitted by subsection (d) hereof, insurance by
insurers of nationally or internationally recognized reputation and
responsibility otherwise conforming with the provisions of said clause (1)
except that (A) the amounts of coverage shall not be required to exceed the
amounts of comprehensive airline liability from time to time applicable to
property owned or leased by Lessee of the same type as such non-operating
property and which is on the ground and not in operation; and (B) the scope
of the risks covered and the type of insurance shall be the same as from
time to time shall be applicable to aircraft owned or leased by Lessee of
the same type as such non-operating property and which is on the ground and
not in operation.

               (b) Insurance Against Loss or Damage to the Aircraft. (1)
Except as provided in clause (2) of this subsection (b), and subject to the
provisions of subsection (d) of this Exhibit H permitting the
self-insurance, Lessee shall maintain or cause to be maintained in effect,
at its or any Sublessee's expense, with insurers of nationally or
internationally recognized responsibility, all-risk aircraft hull insurance
covering the Aircraft and fire and extended coverage and all-risk aircraft
hull insurance covering Engines and Parts while temporarily removed from
the Aircraft and not replaced by similar components; provided that such
insurance shall at all times while the Aircraft is subject to this Lease be
for an amount (taking into account the self-insurance to the extent
permitted by subsection (d) of this Exhibit H) not less than the
Termination Value for the Aircraft; provided further, that, subject to
compliance with subsection (d) of this Exhibit H, such all-risk property
damage insurance covering Engines and Parts temporarily removed from an
Airframe or an airframe or (in the case of Parts) an Engine need be
obtained only to the extent available at reasonable cost (as reasonably
determined by Lessee). In the case of a Loss with respect to an engine
(other than an Engine) installed on the airframe in circumstances which do
not constitute an Event of Loss with respect to the Airframe, Lessor shall
promptly remit any payment made to it of any insurance proceeds in respect
of such Loss to Lessee or any other third party that is entitled to receive
such proceeds.

               Unless an Event of Default has occurred and is continuing,
all losses will be adjusted by Lessee with the insurers. As between Lessor
and Lessee, it is agreed that all insurance payments received as the result
of the occurrence of an Event of Loss will be applied as follows:

                      (x) if such payments are received with respect to the
               Airframe (or the Airframe and the Engines installed
               thereon), (i) unless such property is replaced pursuant to
               the last paragraph of Section 10(a), so much of such
               payments remaining, after reimbursement of Lessor (as
               provided in Section 7.01 of the Trust Agreement) and the
               Owner Participant for reasonable costs and expenses, as
               shall not exceed the Termination Value and the other amounts
               payable pursuant to Section 10(a) hereof shall be applied in
               reduction of Lessee's obligation to pay such Termination
               Value and other amounts payable pursuant to Section 10(a)
               hereof, if not already paid by Lessee, or, if already paid
               by Lessee, shall be applied to reimburse Lessee for its
               payment of such Termination Value and such other amounts
               payable, and the balance, if any, of such payments remaining
               thereafter will be paid over to, or retained by, Lessee (or
               if directed by Lessee, any Sublessee); or (ii) if such
               property is replaced pursuant to the last paragraph of
               Section 10(a), such payments shall be paid over to, or
               retained by, Lessee (or if directed by Lessee, any
               Sublessee), provided that Lessee shall have fully performed
               or, concurrently therewith, will fully perform the terms of
               the last paragraph of Section 10(a) with respect to the
               Event of Loss for which such payments are made; and

                      (y) if such payments are received with respect to an
               Engine under the circumstances contemplated by Section 10(b)
               hereof, so much of such payments remaining after
               reimbursement of Lessor (as provided in Section 7.01 of the
               Trust Agreement) and the Owner Participant for reasonable
               costs and expenses, shall be paid over to, or retained by,
               Lessee (or if directed by Lessee, any Sublessee), provided
               that Lessee shall have fully performed or concurrently
               therewith will fully perform the terms of Section 10(b) with
               respect to the Event of Loss for which such payments are
               made.

               As between Lessor and Lessee, the insurance payments for any
property damage loss to the Airframe or any engine not constituting an
Event of Loss with respect thereto will be applied in payment for repairs
or for replacement property in accordance with the terms of Sections 7 and
8, if not already paid for by Lessee (or any Sublessee), and any balance
(or if already paid for by Lessee (or any Sublessee), all such insurance
proceeds) remaining after compliance with such Sections with respect to
such loss shall be paid to Lessee (or any Sublessee if directed by Lessee).

               (2) During any period that the Aircraft is on the ground and
not in operation, Lessee may carry or cause to be carried, in lieu of the
insurance required by clause (1) above, and subject to self-insurance to
the extent permitted by subsection (d) of this Exhibit H, insurance
otherwise conforming with the provisions of said clause (1) except that the
scope of the risks and the type of insurance shall be the same as from
time to time applicable to aircraft owned or leased by Lessee (or, if a
Sublease is then in effect, by Sublessee) of the same type as the Aircraft
similarly on the ground and not in operation, provided that, subject to
self-insurance to the extent permitted by subsection (d) of this Exhibit H,
Lessee shall maintain insurance against risk of loss or damage to the
Aircraft in an amount at least equal to the Termination Value of the
Aircraft during such period that the Aircraft is on the ground and not in
operation.

               (3) If Lessee (or any Sublessee) shall at any time operate
or propose to operate the Aircraft, Airframe or any Engine (i) in any area
of recognized hostilities or (ii) on international routes, and war-risk,
hijacking or allied perils insurance is maintained by Lessee (or any
Sublessee) with respect to other aircraft owned and operated by Lessee (or
any Sublessee) on such routes or in such areas, Lessee shall maintain or
cause to be maintained war-risk, hijacking and related perils insurance of
substantially the same type carried by major United States commercial air
carriers operating the same or comparable models of aircraft on similar
routes or in such areas and in no event in an amount less than the
Termination Value.

               (c) Reports, etc. Lessee will furnish, or cause to be
furnished, to Lessor, the Indenture Trustee, the Owner Participant and the
Pass Through Trustee, on or before the Delivery Date and on each annual
anniversary date of Lessee's applicable insurance, a report, signed by
Lessee's regular insurance broker or any other independent firm of
insurance brokers reasonably acceptable to Lessor which brokers may be in
the regular employ of Lessee (the "Insurance Brokers"), describing in
reasonable detail the hull and liability insurance (and property insurance
for detached engines and parts) then carried and maintained with respect to
the Aircraft and stating the opinion of such firm that the insurance
complies with the terms hereof; provided, that all information contained in
the foregoing report shall not be made available by Lessor, the Indenture
Trustee or the Owner Participant or the Pass Through Trustee to anyone
except (i) to prospective and permitted transferees of Lessor's, the Owner
Participant's, the Indenture Trustee's or the Pass Through Trustee's
interest or their respective counsel, independent certified public
accountants and independent insurance brokers or other agents, who agree to
hold such information confidential, (ii) to Lessor's, the Owner
Participant's, the Indenture Trustee's or a Pass Through Trustee's counsel
or independent certified public accountants, independent insurance brokers
or agents who agree to hold such information confidential or (iii) as may
be required by any statute, court or administrative order or decree or
governmental ruling or regulation; provided, however that any disclosure
permitted by clause (iii) above shall be made only to the extent necessary
to meet the specific requirements or needs of the Persons to whom such
disclosures are hereby permitted. Lessee will cause such Insurance Broker
to agree to advise Lessor, the Indenture Trustee, the Owner Participant and
the Pass Through Trustee in writing of any act or omission on the part of
Lessee of which it has knowledge and which might invalidate or render
unenforceable, in whole or in part, any insurance on the Aircraft and to
advise in writing at least thirty (30) days (ten (10) days in the case of
war risk and allied perils coverage and ten (10) days notice with respect
to the Electronic Date Recognition Exclusion Limited Coverage Endorsement),
prior to the cancellation or material adverse change of any insurance
maintained pursuant to Section 11, provided that if the notice period
specified above is not reasonably obtainable, the Insurance Broker shall
provide for as long a period of prior notice as shall then be reasonably
obtainable. In addition, Lessee will also cause such Insurance Brokers to
deliver to Lessor, the Indenture Trustee, the Owner Participant and the
Pass Through Trustee, on or prior to the date of expiration of any
insurance policy referenced in a previously delivered certificate of
insurance, a new certificate of insurance, substantially in the same form
as delivered by Lessee to such parties on the Delivery Date except for such
changes in the report or the coverage consistent with the terms hereof. In
the event that Lessee or any Sublessee shall fail to maintain or cause to
be maintained insurance as herein provided, Lessor or the Indenture Trustee
may at its sole option, but shall be under no duty to, provide such
insurance and, in such event, Lessee shall, upon demand, reimburse Lessor
or the Indenture Trustee, as Supplemental Rent, for the cost thereof to
Lessor or the Indenture Trustee, as the case may be; provided, however,
that no exercise by Lessor or the Indenture Trustee, as the case may be, of
said option shall affect the provisions of this Lease, including the
provisions of Section 14(g).

               (d) Self-Insurance. Lessee may self-insure by way of
deductible, premium adjustment or franchise provisions or otherwise
(including, with respect to insurance maintained pursuant to subsection (b)
of this Exhibit H, insuring for an amount that is less than the Termination
Value of the Aircraft) the risks required to be insured against pursuant to
Section 11 under a program applicable to all aircraft (whether owned or
leased) in Lessee's fleet, but in no case shall the aggregate amount of
self-insurance in regard to subsection (a) and (b) of this Exhibit H exceed
for any policy year, with respect to all of the aircraft (whether owned or
leased) in Lessee's fleet (including, without limitation, the Aircraft),
the lesser of (i) 50% of the highest replacement value of any single
aircraft in Lessee's fleet or (ii) 1-1/2% of the average aggregate
insurable value (during the preceding policy year) of all aircraft
(including, without limitation, the Aircraft) on which Lessee carries
insurance, unless an insurance broker of national standing shall certify
that the standard among all other major United States airlines is a higher
level of self-insurance, in which case Lessee may insure the Aircraft to
such higher level. In addition to the foregoing right to self-insure,
Lessee (and any Sublessee) may self-insure to the extent of any applicable
mandatory minimum per aircraft (or, if applicable, per annum or other
period) hull or liability insurance deductible customary in the airline
industry imposed by the aircraft hull or liability insurer.

               (e) Terms of Policies. Any policies of insurance carried in
accordance with subsection (a) or (b) of this Exhibit H and any policies
taken out in substitution or replacement for any of such policies (A) shall
be amended to name the Additional Insureds as their respective interests
may appear, (B) may provide for the self-insurance to the extent permitted
in subsection (d) of this Exhibit H, (C) shall provide that if the insurers
cancel such insurance for any reason whatever or if any material change is
made in such insurance which adversely affects the interest of the
Additional Insureds, or such insurance shall lapse for non-payment of
premium, such cancellation, lapse or change shall not be effective as to
the Additional Insureds for thirty (30) days (ten (10) days in the case of
war risk and allied perils coverage and ten (10) days in the case of the
Electronic Date Recognition Limited Coverage Endorsement) after issuance to
the Additional Insureds, respectively, of written notice by such insurers
of such cancellation, lapse or change; provided, however, that if any
notice period specified above is not reasonably obtainable, such policies
shall provide for as long a period of prior notice as shall then be
reasonably obtainable, (D) shall provide that in respect of the respective
interests of the Additional Insureds in such policies the insurance shall
not be invalidated by any action or inaction of Lessee (or, if any Sublease
is then in effect, any Sublessee) or any other Person and shall insure the
Additional Insureds regardless of any breach or violation of any warranty,
declaration or condition contained in such policies by Lessee (or, if any
Sublease is then in effect, any Sublessee), (E) shall be primary without
right of contribution from any other insurance which is carried by any
Additional Insured, (F) shall expressly provide that all of the provisions
thereof, except the limits of liability, shall operate in the same manner
as if there were a separate policy covering each insured, (G) shall waive
any right of the insurers to any set-off or counterclaim or any other
deduction, whether by attachment or otherwise, in respect of any liability
of any Additional Insured to the extent of any moneys due to any Additional
Insured, and (H) shall provide that (i) in the event of a loss involving
proceeds in excess of $5,000,000, the proceeds in respect of such loss up
to an amount equal to the Termination Value for the Aircraft shall be
payable to Lessor (or, so long as the Trust Indenture shall not have been
discharged, the Indenture Trustee) (except in the case of a loss with
respect to an Engine installed on an airframe other than the Airframe, in
which case Lessee (or any Sublessee) shall arrange for any payment of
insurance proceeds in respect of such loss to be held for the account of
Lessor (or, so long as the Trust Indenture shall not have been discharged,
the Indenture Trustee) whether such payment is made to Lessee (or any
Sublessee) or any third party), it being understood and agreed that in the
case of any payment to Lessor (or the Indenture Trustee) otherwise than in
respect of an Event of Loss, Lessor (or the Indenture Trustee) shall, upon
receipt of evidence satisfactory to it that the damage giving rise to such
payment shall have been repaired or that such payment shall then be
required to pay for repairs then being made, pay the amount of such payment
(and all earnings thereon) to Lessee or its order and (ii) the entire
amount of any loss involving proceeds of $5,000,000 or less or the amount
of any proceeds of any loss in excess of the Termination Value for the
Aircraft shall be paid to Lessee or its order unless an Event of Default
shall have occurred and be continuing and the insurers have been notified
thereof by Lessor or the Indenture Trustee.

        This LEASE AGREEMENT (US Airways, Inc. Trust No. N___U_), dated as
 of __________ __, ____, between FIRST SECURITY BANK, NATIONAL ASSOCIATION,
 not in its individual capacity, except as expressly provided herein, but

 organized and existing pursuant to the laws of the State of Delaware
 ("Lessee");

                            W I T N E S S E T H:

        Section 1.  DEFINITIONS.  Capitalized terms used but not defined
 herein shall have the respective meanings set forth or incorporated by
 reference, and shall be construed and interpreted in the manner described,
 in Annex A.

        Section 2.  ACCEPTANCE AND LEASE.  Lessor hereby agrees (subject
 to satisfaction of the conditions set forth in Section 4(a) of the
 Participation Agreement) to accept the transfer of title from and
 simultaneously to lease to Lessee hereunder, and Lessee hereby agrees
 (subject to satisfaction of the conditions set forth in Section 4(b) of the
 Participation Agreement) to lease from Lessor hereunder, the Aircraft as
 evidenced by the execution by Lessor and Lessee of a Lease Supplement
 leasing the Aircraft hereunder.  Lessee hereby agrees that such acceptance
 of the Aircraft by Lessor shall, without further act, irrevocably
 constitute acceptance by Lessee of such Aircraft for all purposes of this
 Lease.

        Section 3.  TERM AND RENT.

        (a)  Basic Term.  The Basic Term shall commence on the Delivery
 Date and end on the Basic Term Expiration Date.

        (b)  Basic Rent.  On each Rent Payment Date, Basic Rent shall be
 due and payable and Lessee shall pay Basic Rent in Dollars in an amount
 equal to Lessor's Cost multiplied by the percentage for such Rent Payment
 Date specified on Exhibit B-2.  Each payment of Basic Rent shall be final
 and, absent manifest error, Lessee shall not seek, or claim any right, to
 recover all or any part of such payment from Lessor or any other Person for
 any reason whatsoever.  Basic Rent shall be allocated to each Lease Period
 in the amounts set forth for such Lease Period on Exhibit B-3 under the
 caption "Basic Rent Allocation."  [Each installment of Basic Rent shall be
 allocated to the Lease Period(s) specified under the caption "Timing of
 Payments of Allocated Rent" on Exhibit B-3.]

        (c)  Adjustments to Basic Rent.

             (i) In the event of a refinancing as contemplated by Section
      16 of the Participation Agreement, then the Basic Rent percentages
      set forth in Exhibit B, the Termination Value percentages set forth
      in Exhibit C and the EBO Amount set forth on Exhibit D shall be
      recalculated (upwards or downwards) by the Owner Participant as
      contemplated by such Section to (1) maintain the Owner Participant's
      Net Economic Return and (2) to the extent possible consistent with
      clause (1) hereof, minimize the Net Present Value of Rents to Lessee;

             (ii) In the event that Lessee elects to satisfy any indemnity
      obligation under the Tax Indemnity Agreement, then the Basic Rent
      percentages set forth in Exhibit B, the Termination Value percentages
      set forth in Exhibit C and the EBO Amount set forth on Exhibit D
      shall be recalculated (upwards or downwards) by the Owner
      Participant, using the same methods and assumptions (except to the
      extent such assumptions shall be varied to take into account the Loss
      (as defined in the Tax Indemnity Agreement) that is the subject of
      such indemnification and any prior or contemporaneous Loss) used to
      calculate the Basic Rent percentages, the Termination Value
      percentages and the EBO Amount on the Delivery Date, in order to (1)
      maintain the Owner Participant's Net Economic Return and (2) to the
      extent possible consistent with clause (1) hereof, minimize the Net
      Present Value of Rents to Lessee.

             (iii) Whenever Basic Rent is recalculated pursuant to this
      Section 3(c), the Owner Participant shall redetermine the Termination
      Value percentages set forth in Exhibit C and the EBO Amount set forth
      in Exhibit D in a manner consistent with such recalculation.

             (iv) Any recalculation of Basic Rent and Termination Value
      percentages pursuant to this Section 3(c) shall be determined by the
      Owner Participant and shall be subject to the verification procedures
      set forth in Exhibit E hereto. Such recalculated Basic Rent and
      Termination Value percentages shall be set forth in a Lease
      Supplement or an amendment to this Lease.

             (v) Anything contained in the Participation Agreement or this
      Lease to the contrary notwithstanding, (I) each installment of Basic
      Rent payable, whether or not adjusted in accordance with this Section
      3(c), together with any Advance or payment made by Lessee pursuant to
      Section 3(g) and payment of Deferred Equity Amount made by the Owner
      Participant under Section 7(cc) of the Participation Agreement(1)
      shall be, under any circumstances and in any event, in an amount at
      least sufficient for Lessor to pay in full, on the date on which such
      installment of Basic Rent[, Advance or Deferred Equity Amount](2) is
      due, any payments then scheduled to be made on account of the
      principal of, if any, and interest on the Equipment Notes and (II)
      the amount of Termination Value payable on any Termination Date, Loss
      Payment Date or, in the case of payments under Sections 15 and 20,
      Rent Payment Date, whether or not adjusted in accordance with this
      Section 3(c), together with all other amounts payable hereunder by
      Lessee on such date and the amount of the premium, if any, payable by
      Lessor on the Equipment Notes, shall be, under any circumstances and
      in any event, in an amount at least sufficient for Lessor to pay in
      full, on such Termination Date, Loss Payment Date or Rent Payment
      Date, the outstanding principal of, premium, if any, and interest on
      the Equipment Notes. It is agreed that no installment of Basic Rent,
      payment of Termination Value or EBO Amount shall be increased or
      adjusted by reason of (i) any attachment or diversion of Rent on
      account of (A) Lessor Liens or (B) any Loan Participant Lien or other
      Lien on or against the Trust Estate, any part thereof or the
      Operative Documents arising as a result of claims against the
      Indenture Trustee not related to the transactions contemplated by the
      Operative Documents, (ii) any modification of the payment terms of
      the Equipment Notes made without the prior written consent of Lessee
      or (iii) the acceleration of any Equipment Note or Equipment Notes
      due to the occurrence of an Indenture Event of Default which does not
      constitute a Lease Event of Default.

      shall be subject to verification pursuant to Exhibit E.

 promptly to Lessor, or to whomsoever shall be entitled thereto, any and all
 Supplemental Rent constituting Termination Value and Make-Whole Amount as
 the same shall become due and owing and all other amounts of Supplemental
 Rent within five Business Days (5) days after demand or within such other

 Equipment Notes upon redemption of such Equipment Notes in accordance with

 Supplemental Rent, to the extent permitted by applicable law, interest at
 the Past Due Rate on any part of any installment of Basic Rent not paid
 when due for any period for which the same shall be overdue and on any
 payment of Supplemental Rent not paid when due for the period until the
 same shall be paid.

        (e)  Payments in General.  All payments of Rent shall be made
 directly by Lessee (whether or not any Sublease shall be in effect) by wire

 the date such payment of Rent is due); provided that so long as the Trust
 Indenture shall not have been fully discharged, Lessor hereby irrevocably
 directs and Lessee agrees, that, unless the Indenture Trustee shall
 otherwise direct, all Rent payable to Lessor and assigned to the Indenture
 Trustee pursuant to the Trust Indenture shall be paid prior to 11:00 a.m.,
 New York time on the due date thereof in funds of the type specified in
 this Section 3(e) directly to the Indenture Trustee at its account at State

 Asylum Street, Hartford, Connecticut 06103, ABA No. _________, Account No.
 __________, Reference:  US Airways, Inc. 2000-1EETC/US Airways, Inc. Trust
 No. N___U_ (or such other account of the Indenture Trustee in the
 continental United States as the Indenture Trustee shall direct in a notice
 to Lessee at least ten (10) Business Days prior to the date such payment of
 Rent is due).  Lessor hereby directs and Lessee agrees that all payments of
 Supplemental Rent owing to the Indenture Trustee or to a Loan Participant
 or any other Person (other than the Excluded Payments payable to the Owner
 Participant) pursuant to the Participation Agreement shall be made in
 Dollars in immediately available funds prior to 11:00 a.m., New York time,
 on the due date thereof at the office of the Indenture Trustee or at such
 other office of such other financial institution located in the continental
 United States as the party entitled thereto may so direct at least ten (10)
 Business Days prior to the due date thereof.  All payments of Supplemental
 Rent payable to the Owner Participant, to the extent that such amounts
 constitute Excluded Payments, shall be made in Dollars in immediately
 available funds prior to 11:00 a.m., New York time, on the due date
 thereof, to the account of the Owner Participant specified in Schedule I to
 the Participation Agreement (or to such other account as may be specified
 in writing by the Owner Participant from time to time).

        (f)  Business Day Convention.  Notwithstanding anything to the
 contrary contained herein, if any date on which a payment of Rent becomes
 due and payable is not a Business Day, then such payment shall not be made
 on such scheduled date but shall be made on the next succeeding Business
 Day with the same force and effect as if made on such scheduled date and
 (provided such payment is made on such next succeeding Business Day) no
 interest shall accrue on the amount of such payment from and after such
 scheduled date.

        (g)  [Certain Advances, Deductions of Advances.  On the Initial
 Rent Payment Date, prior to noon New York time, Lessee shall advance to the
 Indenture Trustee on behalf of the Owner Trustee an amount that, together
 with the Basic Rent otherwise due on such date, will be equal to the
 scheduled payments of principal and interest then due on the Equipment
 Notes (the amount of such advance to be made by Lessee shall herein be
 called the "Advance"); provided that, Lessee shall be relieved of such
 obligation if, on the Initial Rent Payment Date, the Indenture Trustee
 shall have received the amount payable by the Owner Participant pursuant to
 Section 7(cc) of the Participation Agreement.  In the event Lessee makes an
 Advance pursuant to this Section 3(g) and is not reimbursed therefor by the
 Owner Participant as provided in Section 7(cc) of the Participation
 Agreement, subject to the limitation of Section 3(c)(v), Lessee shall be
 entitled to offset and deduct (without duplication) against each succeeding
 payment (other than as limited by the proviso to this sentence) due from
 Lessee to Persons other than any Note Holder, the Indenture Trustee and
 Lessor in its individual capacity (including, without limitation, Basic
 Rent, payments due under Sections 5, 9, 10, 15, 19 and 20 hereof, payments
 due (only to the extent due to the Owner Participant) under the Tax
 Indemnity Agreement and payments due (only to the extent due to the Owner
 Participant and its Related Indemnitee Group and the Owner Trustee, but
 with respect to the Owner Trustee only to the extent such payments are not
 attributable to the principal or interest on the Equipment Notes) under
 Section 6 of the Participation Agreement) the amounts (including interest
 on such amounts at the Base Rate plus 2% per annum) due and owing by the
 Owner Participant to Lessee from time to time under Section 7(cc) of the
 Participation Agreement until Lessee has been fully reimbursed for such
 amounts (including interest on such amounts at the Base Rate plus 2%);
 provided that, in the case of any payment due from Lessee which is
 distributable under the terms of the Trust Indenture, Lessee's right of
 offset and deduction shall be limited to the amounts distributable to
 Lessor thereunder (and shall not include any amounts distributable to the
 Indenture Trustee in its individual capacity or to any Note Holder), as
 acknowledged by the Indenture Trustee upon 10 days' prior written notice
 from Lessee to the Indenture Trustee, accompanied by a certificate of a
 responsible officer of Lessee certifying that the conditions precedent to
 Lessee's right to effect such an offset have been met.  No such offset or
 aggregate combined effect of separate offsets shall reduce the amount of
 any installment of Basic Rent to an amount that is insufficient to pay in
 full the payments then required to be made on account of the principal or
 interest on the Equipment Notes.  Lessee also will pay to the Indenture
 Trustee on demand, to the extent permitted by applicable law, interest at
 the Past Due Rate on any part of any Advance required to be made by Lessee
 pursuant to this Section 3(g) which is not paid when required to be made
 for any period for which the same shall be overdue.](3)

 purchase the Aircraft in accordance with the terms hereof, if Lessor gives
 written notice to Lessee not less than sixty (60) days nor more than one
 hundred eighty (180) days prior to the end of the Term requesting storage

 maintenance and insurance fees and expenses.  Lessee's obligation to
 arrange parking shall be subject to Lessee and Lessor entering into an
 agreement prior to the commencement of the storage period with the storage
 facility providing, among other things, that Lessor shall bear all
 maintenance charges and other costs incurred relating to such storage.

        (c)  Return of Other Engines.  In the event that any Engine owned

 hereunder, Lessee shall be required to return the Airframe hereunder with
 an Acceptable Alternate Engine meeting the requirements of, and in
 accordance with, Section 10 and Exhibit G hereto.  Thereupon, Lessor will
 transfer to Lessee the Engine constituting part of such Aircraft but not
 installed on such Airframe at the time of the return of the Airframe.

        (d)  Obligations Continue Until Return.  If Lessee shall, for any
 reason, fail to return the Aircraft at the time specified herein, all
 obligations of Lessee under this Lease shall continue in effect with
 respect to the Aircraft until the Aircraft is returned to Lessor and Lessee
 shall pay to Lessor an amount equal to the average daily Basic Rent payable
 by Lessee during the Term for each day after the end of the Term to but
 excluding the day of such return; provided, however, that Lessee shall not
 be responsible for Lessor's failure to accept return of the Aircraft in
 accordance with this Section 5 in a timely manner or for any Rent with
 respect to periods after Lessee has tendered the Aircraft for return in
 accordance with this Lease.  Any Rent owed to Lessor pursuant to this
 Section 5(d) shall be payable upon acceptance of the Aircraft by Lessor or
 on the last day of each calendar month following the last day of the Term
 if the Aircraft has not been accepted earlier.

        Section 6.   LIENS.  Lessee will not directly or indirectly
 create, incur, assume or suffer to exist any Lien on or with respect to the
 Aircraft, title thereto or any interest therein or in this Lease, except
 (i) the respective rights of Lessor as owner of the Aircraft and Lessee as
 herein provided, the Lien of the Trust Indenture, the rights of any
 Sublessee under a sublease permitted hereunder and any other rights of any
 Person existing pursuant to the Operative Documents, (ii) the rights of
 others under agreements or arrangements to the extent permitted by the
 terms of Sections 7(b) and 8(b) hereof, (iii) Lessor Liens, Loan
 Participant Liens and Indenture Trustee's Liens, (iv) Liens for Taxes of
 Lessee (or any Sublessee) either not yet due or being contested in good
 faith by appropriate proceedings so long as such proceedings do not involve
 any material danger of the sale, forfeiture or loss of the Airframe or any
 Engine or any interest therein, (v) materialmen's, mechanics', workmen's,
 repairmen's, employees' or other like Liens arising in the ordinary course
 of Lessee's (or, if a Sublease is then in effect, Sublessee's) business
 (including those arising under maintenance agreements entered into in the
 ordinary course of business) securing obligations that are not overdue for
 a period of more than sixty (60) days or are being contested in good faith
 by appropriate proceedings so long as such proceedings do not involve any
 material danger of the sale, forfeiture or loss of the Airframe or any
 Engine or any interest therein, (vi) Liens arising out of any judgment or
 award against Lessee (or any Sublessee), unless the judgment secured shall
 not, within sixty (60) days after the entry thereof, have been discharged,
 vacated, reversed or execution thereof stayed pending appeal or shall not
 have been discharged, vacated or reversed within sixty (60) days after the
 expiration of such stay, (vii) any other Lien with respect to which Lessee
 (or any Sublessee) shall have provided a bond, cash collateral or other
 security adequate in the reasonable opinion of Lessor and (viii) Liens
 approved in writing by Lessor.  Lessee will promptly, at its own expense,
 take (or cause to be taken) such actions as may be necessary duly to
 discharge any such Lien not excepted above if the same shall arise at any
 time.

        Section 7.   REGISTRATION, MAINTENANCE, OPERATION AND REGISTRATION;
 POSSESSION AND SUBLEASES; INSIGNIA.

        (a)  Registration, Maintenance, Operation and Registration.

             (1) Registration and Maintenance. Lessee, at its own cost and
      expense, shall (or shall cause any Sublessee to): (A) forthwith upon
      the delivery thereof hereunder, cause the Aircraft to be duly
      registered in the name of Lessor, and, subject to clause 3 of this
      Section 7(a) and Section 7(d) of the Participation Agreement, to
      remain duly registered in the name of Lessor under the Transportation
      Code, provided that Lessor shall execute and deliver all such
      documents as Lessee (or any Sublessee) may reasonably request for the
      purpose of effecting and continuing such registration, and shall not
      register the Aircraft or permit the Aircraft to be registered under
      any laws other than the Transportation Code at any time except as
      provided in Section 7(d) of the Participation Agreement and, unless
      the Lien of the Trust Indenture shall have been discharged, shall
      cause the Trust Indenture to be duly recorded and maintained of
      record as a first mortgage on the Aircraft; (B) maintain, service,
      repair and/or overhaul (or cause to be maintained, serviced, repaired
      and/or overhauled) the Aircraft so as to keep the Aircraft in as good
      an operating condition as when delivered by the Seller to Lessee,
      ordinary wear and tear excepted, and as may be necessary to enable
      the applicable airworthiness certification for the Aircraft to be
      maintained in good standing at all times (other than during temporary
      periods of storage or during maintenance or modification permitted
      hereunder) under the Transportation Code, except when all of Lessee's
      Airbus Model A330 aircraft powered by engines of the same type as
      those with which the Airframe shall be equipped at the time of such
      grounding and registered in the United States have been grounded by
      the FAA (although such certification need actually be maintained only
      during such periods as the Aircraft is registered in the United
      States), or the applicable laws of any other jurisdiction in which
      the Aircraft may then be registered from time to time in accordance
      with Section 7(d) of the Participation Agreement, utilizing, except
      during any period that a Sublease is in effect, the same manner and
      standard of maintenance, service, repair or overhaul used by Lessee
      with respect to similar aircraft operated by Lessee in similar
      circumstances and utilizing, during any period that a Sublease is in
      effect, the same manner and standard of maintenance, service, repair
      or overhaul used by the Sublessee with respect to similar aircraft
      operated by the Sublessee in similar circumstances; (C) maintain or
      cause to be maintained in English all records, logs and other
      materials required to be maintained in respect of the Aircraft by the
      FAA or the applicable regulatory agency or body of any other
      jurisdiction in which the Aircraft may then be registered; and (D)
      promptly furnish or cause to be furnished to Lessor and the Owner
      Participant such information as may be required to enable Lessor to
      file any reports required to be filed by Lessor or the Owner
      Participant with any governmental authority because of Lessor's
      ownership of the Aircraft.

             (2) Operation. Lessee will not maintain, use, service, repair,
      overhaul or operate the Aircraft (or permit any Sublessee to
      maintain, use, service, repair, overhaul or operate the Aircraft) in
      violation of any law or any rule, regulation, order or certificate of
      any government or governmental authority (domestic or foreign) having
      jurisdiction over the Aircraft, or in violation of any airworthiness
      certificate, license or registration relating to the Aircraft issued
      by any such authority, except to the extent Lessee (or, if a Sublease
      is then in effect, any Sublessee) is contesting in good faith the
      validity or application of any such law, rule, regulation or order in
      any reasonable manner which does not involve any material risk of
      sale, forfeiture or loss of the Aircraft. Lessee will not operate the
      Aircraft, or permit any Sublessee to operate the Aircraft, in any
      area excluded from coverage by any insurance required by the terms of
      Section 11; provided, however, that the failure of Lessee to comply
      with the provisions of this sentence shall not give rise to an Event
      of Default hereunder if indemnification complying with Section 11(c)
      has been provided or where such failure is attributable to
      extraordinary circumstances involving an isolated occurrence or
      series of incidents not in the ordinary course of the regular
      operations of Lessee (or any Sublessee) such as a hijacking, medical
      emergency, equipment malfunction, weather condition, navigational
      error or other causes beyond the reasonable control of Lessee (or any
      Sublessee).

             (3) Reregistration. At any time after the Depreciation Period,
      Lessor, upon Lessee's compliance with all of the terms of Section
      7(d) of the Participation Agreement, shall, at the request and sole
      expense of Lessee, cooperate with Lessee to take all actions required
      to change the registration of the Aircraft to another country.

        (b)  Possession and Subleases.  Lessee will not, without the prior
 written consent of Lessor, sublease or otherwise in any manner deliver,
 transfer or relinquish possession of the Airframe or any Engine or install
 or permit any Engine to be installed on any airframe other than the
 Airframe or enter into any Wet Lease, and so long as Lessee (or any
 Sublessee) shall comply with the provisions of Section 7(a) and Section 11
 hereof, Lessee may (or may permit any Sublessee to), without the prior
 written consent of Lessor:

             (i) subject the Airframe and the Engines or engines then
      installed thereon to interchange agreements or any Engine to pooling
      or similar arrangements, in each case customary in the airline
      industry and entered into by Lessee (or, if a Sublease is then in
      effect, by Sublessee) in the ordinary course of its business;
      provided that (A) no such agreement or arrangement contemplates or
      requires the transfer of title to the Airframe, (B) if Lessor's title
      to any Engine shall be divested under any such agreement or
      arrangement, such divestiture shall be deemed to be an Event of Loss
      with respect to such Engine and Lessee shall (or shall cause
      Sublessee to) comply with Section 10(b) hereof in respect thereof and
      (C) any interchange agreement to which the Airframe may be subject
      shall be with a U.S. Air Carrier or a Foreign Air Carrier.

             (ii) deliver possession of the Airframe or any Engine to the
      manufacturer thereof (or for delivery thereto) or to any organization
      (or for delivery thereto) for testing, service, repair, maintenance
      or overhaul work on the Airframe or Engine or any part of any thereof
      or for alterations or modifications in or additions to such Airframe
      or Engine to the extent required or permitted by the terms of Section
      8(c) hereof;

             (iii) install an Engine on an airframe owned by Lessee (or any
      Sublessee) free and clear of all Liens, except: (A) Permitted Liens
      and those which apply only to the engines (other than Engines),
      appliances, parts, instruments, appurtenances, accessories,
      furnishings and other equipment (other than Parts) installed on such
      airframe (but not to the airframe as an entirety), (B) the rights of
      third parties under interchange agreements or pooling or similar
      arrangements which would be permitted under clause (i) above,
      provided that Lessor's title to such Engine and, if any Equipment
      Notes shall be outstanding, the first priority Lien of the Trust
      Indenture shall not be divested or impaired as a result thereof and
      (C) mortgage liens or other security interests, provided that (as
      regards this clause (C)) the documents creating such mortgage liens
      or other security interests (or, if applicable, another written
      agreement governing such mortgage liens or other security interests)
      effectively provide that such Engine shall not become subject to the
      lien of such mortgage or security interest, notwithstanding the
      installation thereof on such airframe;

             (iv) install an Engine on an airframe leased to Lessee (or any
      Sublessee) or purchased by Lessee (or any Sublessee) subject to a
      conditional sale or other security agreement, provided that (x) such
      airframe is free and clear of all Liens, except: (A) the rights of
      the parties to the lease or conditional sale or other security
      agreement covering such airframe, or their assignees and (B) Liens of
      the type permitted by clause (iii) of this paragraph (b) and (y) such
      lease, conditional sale or other security agreement effectively
      provides that such Engine shall not become subject to the lien of
      such lease, conditional sale or other security agreement,
      notwithstanding the installation thereof on such airframe;

             (v) install an Engine on an airframe owned by Lessee (or any
      Sublessee), leased to Lessee (or any Sublessee) or purchased by
      Lessee (or any Sublessee) subject to a conditional sale or other
      security agreement under circumstances where neither clause (iii) nor
      clause (iv) of this paragraph (b) is applicable, provided that such
      installation shall be deemed an Event of Loss with respect to such
      Engine and Lessee shall (or shall cause any Sublessee to) comply with
      Section 10(b) hereof in respect thereof, Lessor not intending hereby
      to waive any right or interest it may have to or in such Engine under
      applicable law until compliance by Lessee with such Section 10(b);

             (vi) to the extent permitted by Section 8(b) hereof, subject
      any appliances, Parts or other equipment owned by Lessor and removed
      from the Airframe or any Engine to any pooling arrangement referred
      to in Section 8(b) hereof;

             (vii) subject (or permit any Sublessee to subject) the
      Airframe or any Engine to the Civil Reserve Air Fleet Program and
      transfer (or permit any Sublessee to transfer) possession of the
      Airframe or any Engine to the United States Government or any
      instrumentality or agency thereof pursuant to the Civil Reserve Air
      Fleet Program, so long as Lessee (or any Sublessee) shall (A)
      promptly notify Lessor upon subjecting the Airframe or any Engine to
      the Civil Reserve Air Fleet Program in any contract year and provide
      Lessor with the name and address of the Contracting Office
      Representative for the Air Mobility Command of the United States Air
      Force to whom notice must be given pursuant to Section 15 hereof and
      (B) promptly notify Lessor upon transferring possession of the
      Airframe or any Engine to the United States of America or any agency
      or instrumentality thereof pursuant to such program;

             (viii) for a period not to extend beyond the end of the Term,
      enter into a Wet Lease for the Airframe and Engines or engines then
      installed thereon with any third party; provided that if Lessee (or
      any Sublessee) shall enter into any Wet Lease for a period of more
      than one year (including renewal options) Lessee shall provide Lessor
      written notice of such Wet Lease (such notice to be given prior to
      entering into such Wet Lease, if practicable, but in any event
      promptly after entering into such Wet Lease);

             (ix) for a period not to extend beyond the end of the Term,
      transfer possession of the Airframe or any Engine to the United
      States Government or any instrumentality or agency thereof pursuant
      to a contract, a copy of which shall be provided to Lessor; or

             (x) Lessee may, at any time in its sole discretion, enter into
      any sublease with (A) any Person domiciled in the United States, (B)
      after the Depreciation Period, any Permitted Sublessee or (C) after
      the Depreciation Period, any other Person approved in writing by
      Lessor, which approval shall not be unreasonably withheld; provided,
      however, that no sublease entered into pursuant to this clause (x)
      shall extend beyond the expiration of the Basic Term or any Renewal
      Term then in effect unless Lessee shall have irrevocably committed to
      purchase the Aircraft or renew the Lease in accordance with the terms
      hereof at the end of the Basic Term or Renewal Term, as the case may
      be, to a date beyond the latest permissible expiration date of such
      sublease; provided, further, with respect to a sublease under
      subclauses (B) or (C) of this clause (x), Lessee shall deliver to
      Lessor an opinion of counsel to the effect that (I) the obligations
      of Lessee and the rights and remedies of the Lessor under the Lease
      remain valid, binding and (subject to customary bankruptcy and
      equitable remedies exceptions and to other exceptions customary in
      such Opinions) enforceable; (II) the terms of the sublease constitute
      valid and binding obligations of the Sublessee and (subject to
      customary bankruptcy and equitable remedies exceptions and to other
      exceptions customary in such Opinions) enforceable against Sublessee
      (it being understood that such opinion may be an opinion as to the
      form of the Sublease only and may assume due authorization,
      execution, delivery, requisite approvals and absence of conflicts
      with laws, contracts or organizational documents) under the laws of
      the jurisdiction governing the sublease, (III) that there is no tort
      liability of the owner of an aircraft not in possession thereof under
      the laws of the jurisdiction of the proposed sublessee other than
      tort liability which might have been imposed on such owner under the
      laws of the United States or any state thereof (it being understood
      that in the event such opinion cannot be given such opinion
      requirement shall be waived if insurance reasonably satisfactory to
      Lessor, in its individual capacity, is provided at Lessee's expense)
      and (IV) unless Lessee shall have agreed to provide insurance
      covering the risk of requisition of use of the Aircraft by the
      government of the jurisdiction of the proposed sublessee reasonably
      satisfactory to the Owner Participant, that the laws of such
      jurisdiction require fair compensation by the government of such
      jurisdiction payable in currency freely convertible into Dollars for
      the loss of use of the Aircraft in the event of the requisition by
      such government of such use; and provided finally that, with respect
      to any sublease to any Affiliate of Lessee, (I) such sublessee shall
      be a Certificated Air Carrier and (II) Lessee shall deliver to Lessor
      an opinion of counsel to the effect that Lessee would be entitled to
      the benefits of Section 1110 of the Bankruptcy Code with respect to
      the Aircraft if such Affiliate were to be a debtor in a case under
      Chapter 11 of the Bankruptcy Code, such opinion to be subject to
      customary assumptions and qualifications. Lessee shall provide Lessor
      with a copy of any sublease which has a term of more than one (1)
      year.

        The rights of any Sublessee or other transferee who receives
 possession by reason of a transfer permitted by this paragraph (b) (other
 than the transfer of an Engine which is deemed an Event of Loss) shall be
 subject and subordinate to, and any Sublease permitted by this paragraph
 (b) shall be expressly subject and subordinate to, all the terms of this
 Lease and Lessor's (and so long as the Trust Indenture is in effect, the
 Indenture Trustee's (as Lessor's assignee) rights to repossess and to void
 such Sublease upon such repossession, and Lessee shall remain primarily
 liable hereunder for the performance of all of the terms of this Lease, and
 the terms of any such Sublease shall not permit any Sublessee to take any
 action not permitted to be taken by Lessee in this Lease with respect to
 the Aircraft.  No pooling agreement, sublease or other relinquishment of
 possession of the Airframe or any Engine or Wet Lease shall in any way
 discharge or diminish any of Lessee's obligations to Lessor hereunder or
 constitute a waiver of Lessor's rights or remedies hereunder.  Lessor
 agrees, for the benefit of Lessee (and any Sublessee) and for the benefit
 of any mortgagee or other holder of a security interest in any engine
 (other than an Engine) owned by Lessee (or any Sublessee), any lessor of
 any engine (other than an Engine) leased to Lessee (or any Sublessee) and
 any conditional vendor of any engine (other than an Engine) purchased by
 Lessee (or any Sublessee) subject to a conditional sale agreement or any
 other security agreement, that no interest shall be created hereunder in
 any engine so owned, leased or purchased and that none of Lessor, its
 successors or assigns will acquire or claim, as against Lessee (or any
 Sublessee) or any such mortgagee, lessor or conditional vendor or other
 holder of a security interest or any successor or assignee of any thereof,
 any right, title or interest in such engine as the result of such engine
 being installed on the Airframe.

        Any Wet Lease or similar arrangement under which Lessee maintains
 operational control of the Aircraft shall not constitute a delivery,
 transfer or relinquishment of possession of the Aircraft for purposes of
 this section.  Lessor acknowledges that any consolidation or merger of
 Lessee or conveyance, transfer or lease of all or substantially all of
 Lessee's assets otherwise permitted by the Operative Documents shall not be
 prohibited by this Section.

        (c)  Insignia.  On or prior to the Delivery Date, or as soon as
 practicable thereafter, Lessee agrees to affix and maintain (or cause to be
 affixed and maintained), at its expense, in the cockpit of the Airframe
 adjacent to the airworthiness certificate therein and on each Engine a
 nameplate bearing the inscription:

                                Leased From

    First Security Bank, National Association, as Owner Trustee, Lessor

 and, for so long as the Airframe and each Engine shall be subject to the
 Lien of the Trust Indenture, bearing the following additional inscription:

                                Mortgaged To

 State Street Bank and Trust Company of Connecticut, National Association,
                           as Indenture Trustee

 (such nameplate to be replaced, if necessary, with a nameplate reflecting
 the name of any successor Lessor or successor Indenture Trustee, in each
 case as permitted under the Operative Documents).  Except as above
 provided, Lessee will not allow the name of any Person to be placed on the
 Airframe or on any Engine as a designation that might be interpreted as a
 claim of ownership; provided that nothing herein contained shall prohibit
 Lessee (or any Sublessee) from placing its customary colors and insignia on
 the Airframe or any Engine.

        Section 8.   REPLACEMENT AND POOLING OF PARTS; ALTERATIONS,
 MODIFICATIONS AND ADDITIONS.

        (a)  Replacement of Parts.  Lessee, at its own cost and expense,
 will promptly replace or cause to be replaced all Parts which may from time
 to time be incorporated or installed in or attached to the Airframe or any
 Engine and which may from time to time become worn out, lost, stolen,
 destroyed, seized, confiscated, damaged beyond repair or permanently
 rendered unfit for use for any reason whatsoever, except as otherwise
 provided in paragraph (c) of this Section 8 or if the Airframe or an Engine
 to which a Part relates has suffered an Event of Loss.  In addition, Lessee
 (or any Sublessee) may, at its own cost and expense, remove in the ordinary
 course of maintenance, service, repair, overhaul or testing, any Parts,
 whether or not worn out, lost, stolen, destroyed, seized, confiscated,
 damaged beyond repair or permanently rendered unfit for use, provided that
 Lessee (or any Sublessee), except as otherwise provided in paragraph (c) of
 this Section 8, will, at its own cost and expense, replace such Parts as
 promptly as practicable.  All replacement Parts shall be free and clear of
 all Liens (except for Permitted Liens and pooling arrangements to the
 extent permitted by paragraph (b) of this Section 8 and except in the case
 of replacement property temporarily installed on an emergency basis) and
 shall be in as good operating condition as, and shall have a value and
 utility at least equal to, the Parts replaced assuming such replaced Parts
 were in the condition and repair required to be maintained by the terms
 hereof.  Except as otherwise provided in paragraph (c) of this Section 8,
 all Parts at any time removed from the Airframe or any Engine shall remain
 the property of Lessor, no matter where located, until such time as such
 Parts shall be replaced by Parts which have been incorporated or installed
 in or attached to the Airframe or such Engine and which meet the
 requirements for replacement Parts specified above.  Immediately upon any
 replacement part becoming incorporated or installed in or attached to the
 Airframe or any Engine as above provided, without further act (subject only
 to Permitted Liens and any pooling arrangement to the extent permitted by
 paragraph (b) of this Section 8 and except in the case of replacement
 property temporarily installed on an emergency basis), (i) title to such
 replacement Part shall thereupon vest in Lessor, (ii) such replacement Part
 shall become subject to this Lease and be deemed part of the Airframe or
 such Engine for all purposes hereof to the same extent as the Parts
 originally incorporated or installed in or attached to the Airframe or such
 Engine and (iii) title to the replaced Part shall thereupon vest in Lessee
 (or, if a Sublease is then in effect, any Sublessee), free and clear of all
 rights of Lessor, and shall no longer be deemed a Part hereunder.

        (b)  Pooling of Parts.  Any Part removed from the Airframe or any
 Engine as provided in paragraph (a) of this Section 8 may be subjected by
 Lessee (or any Sublessee) to a normal pooling arrangement customary in the
 airline industry of which Lessee (or, if a Sublease is then in effect, any
 Sublessee) is a party entered into in the ordinary course of Lessee's (or
 any Sublessee's) business; provided that the Part replacing such removed
 Part shall be incorporated or installed in or attached to such Airframe or
 Engine in accordance with such paragraph (a) as promptly as practicable
 after the removal of such removed Part.  In addition, any replacement Part
 when incorporated or installed in or attached to the Airframe or any Engine
 in accordance with such paragraph (a) may be owned by any third party
 subject to such a normal pooling arrangement, provided that Lessee (or any
 Sublessee), at its expense, as promptly thereafter as practicable, either
 (i) causes title to such replacement Part to vest in Lessor in accordance
 with such paragraph (a) by Lessee (or any Sublessee) acquiring title
 thereto for the benefit of, and transferring such title to, Lessor free and
 clear of all Liens except Permitted Liens (other than pooling arrangements)
 or (ii) replaces such replacement Part by incorporating or installing in or
 attaching to the Airframe or Engine a further replacement Part owned by
 Lessee (or any Sublessee) free and clear of all Liens except Permitted
 Liens (other than pooling arrangements) and by causing title to such
 further replacement Part to vest in Lessor in accordance with such
 paragraph (a).

        (c)  Alterations, Modifications and Additions.  Lessee, at its own
 expense, will make (or cause to be made) such alterations and modifications
 in and additions to the Airframe and Engines as may be required from time
 to time to meet the applicable standards of the FAA or any applicable
 regulatory agency or body of any other jurisdiction in which the Aircraft
 may then be registered as permitted by Section 7(d) of the Participation
 Agreement; provided, however, that Lessee (or, if a Sublease is then in
 effect, any Sublessee) may, in good faith, contest the validity or
 application of any such law, rule, regulation or order in any reasonable
 manner which does not adversely affect Lessor or, so long as any Equipment
 Notes are outstanding, the Indenture Trustee.  In addition, Lessee (or any
 Sublessee), at its own expense, may from time to time add further parts or
 accessories and make such alterations and modifications in and additions to
 the Airframe or any Engine as Lessee (or any Sublessee) may deem desirable
 in the proper conduct of its business, including, without limitation,
 removal of Parts which Lessee (or any Sublessee) has determined in its
 reasonable judgment to be obsolete or no longer suitable or appropriate for
 use on the Airframe or such Engine (such parts, "Obsolete Parts"); provided
 that no such alteration, modification or addition shall materially diminish
 the value, utility or remaining useful life of the Airframe or such Engine
 below the value, utility or remaining useful life thereof immediately prior
 to such alteration, modification or addition, assuming the Airframe or such
 Engine was then in the condition required to be maintained by the terms of
 this Lease, except that the value (but not the utility or remaining useful
 life) of the Airframe or any Engine may be reduced by the value of Obsolete
 Parts which shall have been removed so long as the aggregate value of all
 Obsolete Parts which shall have been removed and not replaced shall not
 exceed $750,000 in aggregate value at the time of removal.  Title to all
 Parts incorporated or installed in or attached or added to the Airframe or
 an Engine as the result of such alteration, modification or addition
 (except those parts which (x) Lessee has leased from others and (y) may be
 removed by Lessee pursuant to the next sentence (the "Additional Parts"))
 shall, without further act, vest in Lessor.  Notwithstanding the foregoing
 sentence, Lessee (or any Sublessee) may remove or suffer to be removed any
 Additional Part, provided that such Additional Part (i) is in addition to,
 and not in replacement of or substitution for, any Part originally
 incorporated or installed in or attached to the Airframe or any Engine at
 the time of delivery thereof hereunder or any Part in replacement of, or
 substitution for, any such Part, (ii) is not required to be incorporated or
 installed in or attached or added to the Airframe or any Engine pursuant to
 the terms of Section 7 hereof or the first sentence of this paragraph (c)
 and (iii) can be removed from the Airframe or such Engine without
 diminishing or impairing the value, utility or remaining useful life which
 the Airframe or such Engine would have had at the time of removal had such
 alteration, modification or addition not occurred.  Upon the removal by
 Lessee (or Sublessee) of any Part as provided above, title thereto shall,
 without further act, vest in Lessee (or any Sublessee, as the case may be)
 and such Part shall no longer be deemed part of the Airframe or Engine from
 which it was removed.  Any Part not removed by Lessee (or any Sublessee) as
 above provided prior to the return of the Airframe or Engine to Lessor
 hereunder shall remain the property of Lessor.

        (d)  Certain Matters Regarding Passenger Convenience Equipment.
 Lessee may install on the Airframe, subject to the requirements of Section
 8(c) above, Passenger Convenience Equipment that is (i) owned by another
 Person and leased to Lessee, (ii) sold to Lessee by another Person subject
 to a conditional sale contract or other retained security interest,
 (iii) leased to Lessee pursuant to a lease which is subject to a security
 interest in favor of another Person or (iv) installed on the Aircraft
 subject to a license granted to Lessee by another Person, and in any such
 case the Lessor and the Indenture Trustee will not acquire or claim, as
 against any such other Person, any right, title or interest in any such
 Passenger Convenience Equipment solely as a result of its installation on
 the Airframe.  Lessee agrees that if any such Person repossesses such
 Passenger Convenience Equipment, Lessee will (or will cause such Person to)
 restore the Aircraft to the condition it would have been in had the
 installation of such Passenger Convenience Equipment not occurred.

        Section 9.   VOLUNTARY TERMINATION.

        (a)  Termination Event.

             (i) Lessee shall have the right to elect to terminate this
      Lease (x) on any Rent Payment Date occurring on or after the close of
      the calendar year in which the seventh (7th) anniversary of the
      Delivery Date occurs if Lessee shall have made the good faith
      determination, which shall be evidenced by a certificate of a
      responsible officer of Lessee, that the Aircraft is obsolete or
      surplus to its needs or (y) on the tenth, thirteenth and sixteenth
      anniversaries of the Delivery Date.

             (ii) Lessee shall give to Lessor at least one hundred twenty
      (120) days revocable advance written notice of Lessee's intention to
      so terminate this Lease (any such notice, a "Termination Notice")
      specifying (A) the Rent Payment Date on which Lessee intends to
      terminate this Lease in accordance with this Section 9 (such
      specified date, a "Termination Date"), (B) either (I) that Lessee has
      determined that the Aircraft is obsolete or surplus to its needs or
      (II) that it is exercising its termination option pursuant to Section
      9(a)(i)(y) and (C) in the case of a Termination under Section
      9(a)(i)(y) whether Lessee elects to purchase the Aircraft pursuant to
      Section 9(d). Any Termination Notice shall become irrevocable fifteen
      (15) days prior to the Termination Date.

        (b)  Optional Sale of the Aircraft; Lessor Retention Option;
 Revocation of Termination Notice.  In the event that Lessee shall have
 exercised its right to terminate this Lease under Section 9(a)(i)(y) but
 shall not have elected to purchase the Aircraft pursuant to Section 9(d),
 or Lessee shall have elected to terminate this Lease pursuant to Section
 9(a)(i)(x), then during the period from the giving of the Termination
 Notice until the proposed Termination Date (unless Lessee shall have
 revoked the Termination Notice specifying such proposed Termination Date or
 Lessor shall have irrevocably elected to retain the Aircraft pursuant to
 this Section 9(b)), Lessee, as agent for Lessor and at no expense to
 Lessor, shall use commercially reasonable efforts to obtain bids for the
 purchase of the Aircraft and, in the event it receives any bid, Lessee
 shall, within five (5) Business Days after receipt thereof and at least ten
 (10) Business Days prior to the proposed Termination Date, certify to
 Lessor in writing the amount and terms of such bid, and the name and
 address of the party or parties (who shall not be Lessee or any Affiliate
 of Lessee or any Person with whom Lessee or any such Affiliate has an
 arrangement or understanding regarding the future use of the Aircraft by
 Lessee or any such Affiliate but who may be the Owner Participant, any
 Affiliate thereof or any Person contacted by the Owner Participant)
 submitting such bid.  Subject to the next succeeding sentence, on or before
 the Termination Date, subject to the release of all mortgage and security
 interests with respect to the Aircraft under the Trust Indenture:  (1)
 Lessee shall deliver the Aircraft, or cause the Aircraft to be delivered,
 to the bidder(s), if any, which shall have submitted the highest bid
 therefor at least ten (10) Business Days prior to such Termination Date, in
 the same manner and in the same condition and otherwise in accordance with
 all the terms of this Lease as if delivery were made to Lessor pursuant to
 Section 5, and shall duly transfer to Lessor title to any engines not owned
 by Lessor all in accordance with the terms of Section 5, (2) Lessor shall
 comply with the terms of the Trust Indenture and shall, without recourse or
 warranty (except as to the absence of Lessor Liens), subject to prior or
 concurrent payment by Lessee of all amounts due under clause (3) of this
 sentence, sell all of Lessor's right, title and interest in and to the
 Aircraft for cash in Dollars to such bidder(s), the total sales price
 realized at such sale to be retained by Lessor and (3) Lessee shall
 simultaneously pay or cause to be paid to Lessor in funds of the type
 specified in Section 3(e) hereof, an amount equal to the sum of (A) the
 excess, if any, of (i) the Termination Value for the Aircraft, computed as
 of the Termination Date, over (ii) the sales price of the Aircraft sold by
 Lessor after deducting the reasonable expenses incurred by Lessor in
 connection with such sale, (B) all unpaid Basic Rent with respect to the
 Aircraft due prior to (but not on) such Termination Date and all
 Supplemental Rent due by Lessee under this Lease (including, without
 limitation, Supplemental Rent in respect of the Make-Whole Amount, if any,
 payable in connection with a prepayment of the Equipment Notes, and upon
 such payment Lessor simultaneously will transfer to Lessee, without
 recourse or warranty (except as to the absence of Lessor Liens), all of
 Lessor's right, title and interest in and to any Engines constituting part
 of the Aircraft which were not sold with the Aircraft.  Notwithstanding the
 preceding sentence, Lessor may, if Lessee has not revoked the Termination
 Notice, elect to retain title to the Aircraft.  If Lessor so elects, Lessor
 shall give to Lessee irrevocable written notice of such election within
 thirty (30) days of its receipt of a Termination Notice accompanied by an
 irrevocable undertaking by the Owner Participant to make available to the
 Lessor for payment to the Indenture Trustee on the Termination Date the
 amount required to pay in full the unpaid principal amount of the Equipment
 Notes outstanding on the Termination Date plus interest accrued thereon
 through the Termination Date together with the Make-Whole Amount, if any,
 due on the Equipment Notes, if the same is not otherwise paid.  Upon
 receipt of notice of such an election by Lessor and the accompanying
 undertaking by the Owner Participant, Lessee shall cease its efforts to
 obtain bids as provided above and shall reject all bids theretofore or
 thereafter received.  On the Termination Date, Lessor shall (subject to the
 payment by Lessee of all Rent due on or prior to such date, other than any
 Basic Rent due on such date) pay in full the unpaid principal amount of the
 Equipment Notes outstanding on the Termination Date plus interest accrued
 thereon through the Termination Date together with all Make-Whole Amount,
 if any, due on the Equipment Notes and, so long as the Equipment Notes are
 paid as aforesaid, Lessee shall deliver the Airframe and Engines or engines
 to Lessor in accordance with Section 5 and shall pay all Basic Rent due
 prior to the Termination Date and all Supplemental Rent (other than Make-
 Whole Amount or Termination Value) due on or prior to the Termination Date.
 If no sale shall have occurred on the Termination Date and Lessor has not
 made the payment contemplated by the preceding sentence and thereby caused
 this Lease to terminate, or if Lessee revokes its Termination Notice, this
 Lease shall continue in full force and effect as to the Aircraft, Lessee
 shall pay the reasonable costs and expenses incurred by the Owner
 Participant and Lessor (unless such failure to terminate the Lease is a
 consequence of the failure of Lessor or the Owner Participant without due
 cause to make, or cause to be made, the payment referred to in the
 immediately preceding sentence, in which case Lessor and the Owner
 Participant shall be responsible for damages), if any, in connection with
 preparation for such sale and Lessee may give one or more additional
 Termination Notices in accordance with Section 9(a), subject to the last
 sentence of this Section 9(b).  In the event of any such sale or such
 retention of the Aircraft by Lessor and upon compliance by Lessee with the
 provisions of this paragraph, the obligation of Lessee to pay Basic Rent or
 any other amounts hereunder shall cease to accrue and this Lease shall
 terminate.  Lessor may, but shall be under no duty to, solicit bids,
 inquire into the efforts of Lessee to obtain bids or otherwise take any
 action in connection with any such sale other than to transfer (in
 accordance with the foregoing provisions) to the purchaser named in the
 highest bid certified by Lessee to Lessor all of Lessor's right, title and
 interest in the Aircraft, against receipt of the payments provided herein.
 Lessee may revoke a Termination Notice given pursuant to Section 9(a) no
 more than two (2) times during the Term.

        (c)  Termination as to Engines; Replacement.  Lessee shall have the
 right at its option at any time during the Term, on at least thirty (30)
 days prior written notice, to terminate this Lease with respect to any
 Engine.  In such event, and prior to the date of such termination, Lessee
 shall replace such Engine hereunder by complying with the terms of Section
 10(b) to the same extent as if an Event of Loss had occurred with respect
 to such Engine, and Lessor shall transfer such right, title and interest as
 it may have to the replaced Engine as provided in Section 5(b).  No
 termination of this Lease with respect to any Engine as contemplated by
 this Section 9(c) shall result in any reduction of Basic Rent.

        (d)  Special Purchase Options.  If Lessee exercises its right to
 terminate this Lease under Section 9(a)(1)(y), gives its notice pursuant to
 Section 9(a)(ii) to purchase the Aircraft pursuant to this Section 9(d) and
 such notice becomes irrevocable, then on the Termination Date specified in
 Section 9(a), Lessee shall purchase the Aircraft at the greater of (i) the
 Termination Value on the Termination Date, or (ii) its fair market sales
 value on the Termination Date (determined in accordance with Section 19(c)
 hereof), provided that Lessee shall have also paid the amounts specified in
 (A) and (B) of the following sentence.  In such event, Lessor shall,
 without recourse or warranty (except as to the absence of Lessor Liens),
 sell the Aircraft to Lessee in exchange for the payment in immediately
 available funds in an amount equal to the greater of (x) the Termination
 Value for the Aircraft, computed as of the Termination Value Date, or (y)
 the fair market sales value of the Aircraft on the Termination Date,
 provided that on such date the Lessee shall have also paid to the Lessor
 the sum of (A) all unpaid Basic Rent with respect to the Aircraft due prior
 to (but not on) such Termination Date and all unpaid Supplemental Rent with
 respect to the Aircraft due on or prior to such Termination Date plus (B)
 all reasonable expenses incurred by Lessor and the Owner Participant in
 connection with such sale.  Upon payment in full of the amounts required to
 be paid and the performance of all acts required to be performed by Lessee
 pursuant to the preceding sentence, (i) the obligation of Lessee to pay
 Basic Rent hereunder with respect to the Aircraft due on or after the
 Termination Date shall terminate with respect to the Aircraft, (ii) this
 Lease shall terminate on the Termination Date, (iii) Lessor will transfer
 to or at the direction of Lessee, without recourse or warranty (except as
 to the absence of Lessor Liens), all of Lessor's right, title and interest
 in the Airframe and Engines and furnish to or at the direction of the
 Lessee a bill of sales in form and substance reasonably satisfactory to
 Lessee, evidencing such transfer.  Notwithstanding the foregoing, Lessee
 may, in accordance with Section 7(u) of the Participation Agreement, assume
 the principal amount of the Equipment Notes then outstanding on any
 Termination Date specified in Section 9(a), in which event the Lessee will
 receive a credit against the purchase price otherwise payable pursuant to
 this Section 9(d) in an amount equal to the principal amount of Equipment
 Notes so assumed.

        Section 10.   LOSS, DESTRUCTION, REQUISITION, ETC.

        (a)  Event of Loss with Respect to the Aircraft.  Upon the
 occurrence of an Event of Loss with respect to the Airframe or the Airframe
 and the Engines and/or engines then installed thereon, Lessee shall
 forthwith (and in any event, within fifteen (15) days after such
 occurrence) give Lessor written notice of such Event of Loss, and, within
 sixty (60) days after such Event of Loss, Lessee shall give Lessor written
 notice of its election to perform one of the following options (it being
 agreed that if Lessee shall not have given such notice of election within
 such period, Lessee shall be deemed to have elected the option set forth in
 clause (i) below).  Lessee may elect either to:

             (i) make the payments specified in this clause (i), in which
      event not later than the earlier of (x) the Business Day next
      succeeding the 120th day following the occurrence of such Event of
      Loss or (y) an earlier Business Day irrevocably specified fifteen
      (15) days in advance by notice from Lessee to Lessor and the
      Indenture Trustee (the "Loss Payment Date"), Lessee shall pay or
      cause to be paid to Lessor in funds of the type specified in Section
      3(e) hereof, an amount equal to the Termination Value of the Aircraft
      corresponding to the Termination Value Date occurring on or
      immediately following the Loss Payment Date (the "Determination
      Date"); provided that in any instance in which the applicable Loss
      Payment Date shall occur after the final day of the Term, the
      Determination Date shall be the last Termination Value Date in the
      Term, and the Termination Value shall be reduced by any amount of
      Basic Rent due on the Determination Date that has actually been paid;

             (ii) substitute an aircraft or an airframe or an airframe and
      one or more engines, as the case may be; provided that, if Lessee
      does not perform its obligation to effect such substitution in
      accordance with this Section 10(a), during the period of time
      provided herein, then Lessee shall pay or cause to be paid to Lessor
      on the Business Day next succeeding the 120th day following the
      occurrence of such Event of Loss the amount specified in clause (i)
      above.

        At such time as Lessor shall have received the amounts specified in
 clause (i) above, together with all other amounts that then may be due
 hereunder (excluding Basic Rent due on the Determination Date but
 including, without limitation, all Basic Rent due before the date of such
 payment and all Supplemental Rent), under the Participation Agreement and
 under the Tax Indemnity Agreement, (1) the obligation of Lessee to pay the
 installments of Basic Rent shall cease to accrue, (2) this Lease shall
 terminate, (3) Lessor will comply with the terms of the Trust Indenture and
 transfer to or at the direction of Lessee, without recourse or warranty
 (except as to the absence of Lessor Liens), all of Lessor's right, title
 and interest in and to the Airframe and any Engines subject to such Event
 of Loss, as well as any Engines not subject to such Event of Loss, and
 furnish to or at the direction of Lessee a bill of sale in form and
 substance reasonably satisfactory to Lessee (or any Sublessee), evidencing
 such transfer and (4) Lessee will be subrogated to all claims of Lessor, if
 any, against third parties, for damage to or loss of the Airframe and any
 Engines which were subject to such Event of Loss to the extent of the then
 insured value of the Aircraft.

        In the event Lessee shall elect to substitute an aircraft (or an
 airframe or an airframe and one or more engines, as the case may be) Lessee
 shall, at its sole expense, not later than the Business Day next succeeding
 the 120th day following the occurrence of such Event of Loss, (A) convey or
 cause to be conveyed to Lessor and to be leased by Lessee hereunder, an
 aircraft (or an airframe or an airframe and one or more engines which,
 together with the Engines constituting a part of the Aircraft but not
 installed thereon at the time of such Event of Loss constitute the
 Aircraft) free and clear of all Liens (other than Permitted Liens) and
 having a value, utility and remaining useful life at least equal to the
 Aircraft subject to such Event of Loss assuming that the Aircraft had been
 maintained in accordance with this Lease and (B) prior to or at the time of
 any such substitution, Lessee (or any Sublessee), at its own expense, will
 (1) furnish Lessor with a full warranty bill of sale and a Federal Aviation
 Administration bill of sale, in form and substance reasonably satisfactory
 to Lessor, evidencing such transfer of title, (2) cause a Lease Supplement
 and a Trust Supplement to be duly executed by Lessee and filed for
 recording pursuant to the Transportation Code, or the applicable laws,
 rules and regulations of any other jurisdiction in which the Airframe may
 then be registered as permitted by Section 7(d) of the Participation
 Agreement, (3) cause a financing statement or statements with respect to
 such substituted property to be filed in such place or places as are deemed
 necessary or desirable by Lessor to perfect its and the Indenture Trustee's
 interest therein and herein, (4) furnish Lessor with such evidence of
 compliance with the insurance provisions of Section 11 with respect to such
 substituted property as Lessor may reasonably request, (5) furnish Lessor
 with copies of the documentation required to be provided by Lessee pursuant
 to Section 5.06 of the Trust Indenture, and Lessor simultaneously will
 comply with the terms of the Trust Indenture and transfer to or at the
 direction of Lessee, without recourse or warranty (except as to the absence
 of Lessor Liens), all of Lessor's right, title and interest, if any, in and
 to the Aircraft or the Airframe and one or more Engines, as the case may
 be, with respect to which such Event of Loss occurred and furnish to or at
 the direction of Lessee a bill of sale in form and substance reasonably
 satisfactory to Lessee (or any Sublessee), evidencing such transfer, (6)
 furnish Lessor with an opinion of counsel (which shall be Skadden, Arps,
 Slate, Meagher & Flom LLP or Skadden, Arps, Slate, Meagher & Flom
 (Illinois) and, if not, other counsel chosen by Lessee and reasonably
 acceptable to Lessor) reasonably satisfactory to Lessor to the effect that
 Lessor and the Indenture Trustee will be entitled to the benefits of
 Section 1110 of the U.S. Bankruptcy Code with respect to the substitute
 aircraft, provided that such opinion need not be delivered to the extent
 that immediately prior to such substitution the benefits of Section 1110 of
 the U.S. Bankruptcy Code were not, solely by reason of a change in law or
 governmental interpretation thereof after the date hereof, available to
 Lessor and, so long as any Equipment Notes are outstanding, the Indenture
 Trustee (it being agreed that such opinion may contain customary
 qualifications and assumptions) and (7) Lessee will be subrogated to all
 claims of Lessor, if any, against third parties for damage to or loss of
 the Airframe and any Engine which were subject to such Event of Loss to the
 extent of the then insured value of the Aircraft.  For all purposes hereof,
 the property so substituted shall after such transfer be deemed part of the
 property leased hereunder and shall be deemed an "Aircraft", "Airframe" and
 "Engine", as the case may be, as defined herein.  No Event of Loss with
 respect to the Airframe or the Airframe and the Engines or engines then
 installed thereon for which substitution has been elected pursuant to
 Section 10(a)(ii) hereof shall result in any reduction in Basic Rent.

        (b)  Event of Loss with Respect to an Engine.  Upon the occurrence
 of an Event of Loss with respect to an Engine under circumstances in which
 there has not occurred an Event of Loss with respect to the Airframe,
 Lessee shall forthwith (and in any event, within fifteen days after such
 occurrence) give Lessor written notice thereof and shall, within one
 hundred twenty (120) days after the occurrence of such Event of Loss,
 convey or cause to be conveyed to Lessor, as replacement for the Engine
 with respect to which such Event of Loss occurred, title to an Acceptable
 Alternate Engine.  Prior to or at the time of any such conveyance, Lessee,
 at its own expense, will (i) furnish Lessor with a warranty (as to title)
 bill of sale, in form and substance reasonably satisfactory to Lessor, with
 respect to such Acceptable Alternate Engine, (ii) cause a Lease Supplement
 and Trust Supplement to be duly executed by Lessee and to be filed for
 recording pursuant to the Transportation Code, or the applicable laws,
 rules and regulations of any other jurisdiction in which the Airframe may
 then be registered as permitted by Section 7(d) of the Participation
 Agreement, (iii) furnish Lessor with such evidence of compliance with the
 insurance provisions of Section 11 hereof with respect to such replacement
 engine as Lessor may reasonably request and furnish Lessor with copies of
 the documentation required to be provided by Lessee pursuant to Section
 5.06 of the Trust Indenture, and Lessor will comply with the terms of the
 Trust Indenture and transfer to or at the direction of Lessee without
 recourse or warranty (except as to absence of Lessor Liens) all of Lessor's
 right, title and interest, if any, in and to (A) the Engine with respect to
 which such Event of Loss occurred and furnish to or at the direction of
 Lessee a bill of sale in form and substance reasonably satisfactory to
 Lessee, evidencing such transfer and (B) all claims, if any, against third
 parties, for damage to or loss of the Engine subject to such Event of Loss,
 and such Engine shall thereupon cease to be the Engine leased hereunder.
 For all purposes hereof, each such replacement engine shall, after such
 conveyance, be deemed part of the property leased hereunder, and shall be
 deemed an "Engine".  No Event of Loss with respect to an Engine under the
 circumstances contemplated by the terms of this paragraph (b) shall result
 in any reduction in Basic Rent.

        (c)  Application of Payments from Governmental Authorities for
 Requisition of Title, etc.  Any payments (other than insurance proceeds the
 application of which is provided for in Section 11) received at any time by
 Lessor or by Lessee from any governmental authority or other Person with
 respect to an Event of Loss will be applied as follows:

             (i) if payments are received with respect to the Airframe (or
      the Airframe and any Engine or engines then installed thereon), (A)
      unless the same are replaced pursuant to the last paragraph of
      Section 10(a), after reimbursement of Lessor (as provided in Section
      7.01 of the Trust Agreement) for reasonable costs and expenses, so
      much of such payments remaining as shall not exceed the Termination
      Value required to be paid by Lessee pursuant to Section 10(a), shall
      be applied in reduction of Lessee's obligation to pay Termination
      Value, if not already paid by Lessee, or, if already paid by Lessee,
      shall be applied to reimburse Lessee for its payment of Termination
      Value, and following the foregoing application, the balance, if any,
      of such payments will be paid over to, or retained by Lessee,
      provided that Lessor shall be entitled to so much of the excess, if
      any, of such payment over the greater of (x) the Termination Value
      and (y) the fair market value of the Aircraft as Lessor shall
      demonstrate to Lessee's reasonable satisfaction is attributable to
      compensation for loss of Lessor's interest in the Aircraft as
      distinguished from the loss of use of the Aircraft; or (B) if such
      property is replaced pursuant to the last paragraph of Section 10(a),
      such payments shall be paid over to, or retained by, Lessee; and

             (ii) if such payments are received with respect to an Engine
      under circumstances contemplated by Section 10(b) hereof, so much of
      such payments remaining after reimbursement of Lessor (as provided
      for in Section 7.01 of the Trust Agreement) for reasonable costs and
      expenses shall be paid over to, or retained by, Lessee.

        (d)  Requisition for Use of the Aircraft by the United States
 Government or the Government of Registry of the Aircraft.  In the event of
 the requisition for use of the Airframe and the Engines or engines
 installed on the Airframe during the Term by the United States Government
 or any other government of registry of the Aircraft or any instrumentality
 or agency of any thereof, Lessee shall promptly notify Lessor of such
 requisition, and all of Lessee's obligations under this Lease with respect
 to the Aircraft shall continue to the same extent as if such requisition
 had not occurred (except to the extent that any failure or delay in
 repairing or maintaining the Aircraft shall have been caused by such
 requisition), provided that if such Airframe and Engines or engines
 installed thereon are not returned by such government prior to the end of
 the Term, Lessee shall be obligated to return the Airframe and such Engines
 or engines to Lessor pursuant to, and in all other respects in compliance
 with the provisions of, Section 5 promptly on the date of such return by
 such government.  If, in the event of any such requisition, Lessee shall
 fail to return the Aircraft on or before the thirtieth (30th) day beyond
 the end of the Term, such failure shall constitute an Event of Loss which
 shall be deemed to have occurred on the last day of the Term and in such
 event Lessee shall make the payment contemplated by Section 10(a)(i) in
 respect of such Event of Loss; provided, however, that Lessor may notify
 Lessee in writing on or before the twentieth (20th) day prior to the last
 day of the Term that, in the event Lessee shall fail by reason of such
 requisition to return the Airframe and such Engines or engines on or before
 the thirtieth day beyond the end of the Term, such failure shall not be
 deemed an Event of Loss.  Upon the giving of such notice and such failure
 to return by the thirtieth (30th) day beyond the end of the Term, Lessee
 shall be relieved of all of its obligations pursuant to the provisions of
 Section 5 (but not under any other Section), except that if any engine not
 owned by Lessor shall then be installed on the Airframe, Lessee will, at no
 cost to Lessor, furnish, or cause to be furnished, to Lessor a full
 warranty (as to title) bill of sale with respect to each such engine, in
 form and substance reasonably satisfactory to Lessor (together with an
 opinion of counsel (which may be Lessee's General Counsel, Deputy General
 Counsel, Associate General Counsel or Assistant General Counsel) to the
 effect that such full warranty bill of sale has been duly authorized and
 delivered and is enforceable in accordance with its terms and that such
 engines are free and clear of Liens other than Lessor Liens, Loan
 Participant Liens and Indenture Trustee Liens), against receipt from Lessor
 of a bill of sale evidencing the transfer, without recourse or warranty
 (except as to the absence of Lessor Liens), by Lessor to Lessee or its
 designee of all of Lessor's right, title and interest in and to any Engine
 constituting part of the Aircraft but not then installed on the Airframe.
 All payments received by Lessor or Lessee from such government for the use
 of such Airframe and Engines or engines during the Term shall be paid over
 to, or retained by, Lessee (or, if directed by Lessee, any Sublessee); and
 all payments received by Lessor or Lessee from such government for the use
 of such Airframe and Engines or engines after the end of the Term shall be
 paid over to, or retained by, Lessor unless Lessee shall have exercised its
 purchase option hereunder, in which case such payments shall be made to
 Lessee.

        (e)  Requisition for Use of an Engine by the United States
 Government or the Government of Registry of the Aircraft.  In the event of
 the requisition for use of an Engine by the United States Government or any
 other government of registry of the Aircraft or any agency or
 instrumentality of any thereof (other than in the circumstances
 contemplated by paragraph (d)), Lessee shall replace such Engine hereunder
 by complying (or causing any Sublessee to comply) with the terms of Section
 10(b) to the same extent as if an Event of Loss had occurred with respect
 thereto, and, upon compliance with Section 10(b) hereof, any payments
 received by Lessor or Lessee from such government with respect to such
 requisition shall be paid over to, or retained by, Lessee.

        (f)  Application of Payments During Existence of Event of Default.
 Any amount referred to in this Section 10 which is payable to or retainable
 by Lessee (or any Sublessee) shall not be paid to or retained by Lessee (or
 such Sublessee) if at the time of such payment or retention an Event of
 Default has occurred and is continuing, but shall be held by or paid over
 to Lessor as security for the obligations of Lessee (or such Sublessee)
 under this Lease and, if an Event of Default has occurred and is continuing
 hereunder, applied against Lessee's obligations hereunder as and when due.
 At such time as there shall not be continuing any such Event of Default,
 such amount shall be paid to Lessee (or such Sublessee) to the extent not
 previously applied in accordance with the preceding sentence.

        Section 11.   INSURANCE.

        (a)  Lessee's Obligation to Insure.  Lessee shall comply with, or
 cause to be complied with, each of the provisions of Exhibit H, which
 provisions are hereby incorporated by this reference as if set forth in
 full herein.

        (b)  Additional Insurance by Lessor and Lessee.  Lessee (and any
 Sublessee) may at its own expense carry insurance with respect to its
 interest in the Aircraft in amounts in excess of that required to be
 maintained by this Section 11; the Owner Participant may carry for its own
 account at its sole cost and expense insurance with respect to its interest
 in the Aircraft, provided that such insurance does not prevent Lessee (or
 any Sublessee) from carrying the insurance required or permitted by this
 Section 11 or adversely affect such insurance or the cost thereof.

        (c)  Indemnification by Government in Lieu of Insurance.
 Notwithstanding any provisions of this Section 11 requiring insurance,
 Lessor agrees to accept, in lieu of insurance against any risk with respect
 to the Aircraft, indemnification from, or insurance provided by, the United
 States Government or any agency or instrumentality thereof, or, upon the
 written consent of Lessor, other government of registry of the Aircraft or
 agency or instrumentality thereof, against such risk in an amount which,
 when added to the amount of insurance against such risk maintained by
 Lessee (or any Sublessee) shall be at least equal to the amount of
 insurance against such risk otherwise required by this Section 11 (taking
 into account self-insurance permitted by Exhibit H hereto).

        (d)  Application of Payments During Existence of an Event of
 Default. Any amount referred to in paragraph (b) of Exhibit H hereto which
 is payable to or retainable by Lessee (or any Sublessee) shall not be paid
 to or retained by Lessee (or any Sublessee) if at the time of such payment
 or retention an Event of Default has occurred and is continuing, but shall
 be held by or paid over to Lessor as security for the obligations of Lessee
 under this Lease and, if Lessor declares this Lease to be in default
 pursuant to Section 15 hereof, applied against Lessee's obligations
 hereunder as and when due.  At such time as there shall not be continuing
 any such Event of Default, such amount shall be paid to Lessee to the
 extent not previously applied in accordance with the preceding sentence.

        Section 12.   INSPECTION.  At all reasonable times and upon at
 least 15 days prior written notice to Lessee, the Owner Participant or the
 Indenture Trustee, or their respective authorized representatives, may
 inspect the Aircraft and inspect and make copies of the books and records
 of Lessee and any Sublessee required to be maintained by the Federal
 Aviation Administration or the regulatory agency or body of another
 jurisdiction in which the Aircraft is then registered relating to the
 maintenance of the Aircraft (at Lessor's, the Owner Participant's or the
 Indenture Trustee's risk and expense, as the case may be) and shall keep
 any information or copies obtained thereby confidential and shall not
 disclose the same to any Person, except (A) to the Lessor, the Note Holders
 and to prospective and permitted transferees of Lessor's, the Owner
 Participant's, the Note Holders' or the Indenture Trustee's interest (and
 such prospective and permitted transferee's counsel, independent insurance
 advisors or other agents) who agree to hold such information confidential,
 (B) to Lessor's, the Owner Participant's, the Note Holders' or the
 Indenture Trustee's counsel, independent insurance advisors or other agents
 who agree to hold such information confidential, or (C) as may be required
 by any statute, court or administrative order or decree or governmental
 ruling or regulation, provided, however, that any and all disclosures
 permitted by clause (C) above shall be made only to the extent necessary to
 meet the specific requirements or needs of the Persons for whom such
 disclosures are hereby permitted.  Any such inspection of the Aircraft
 shall be subject to Lessee's safety and security rules applicable to the
 location of the Aircraft, shall be a visual, walk-around inspection of the
 interior and exterior of the Aircraft and shall not include opening any
 panels, bays or the like without the express consent of Lessee (except in
 connection with a heavy maintenance visit when a panel, bay or the like is
 scheduled or required to be opened), which consent Lessee may in its sole
 discretion withhold; provided that no exercise of such inspection right
 shall interfere with the normal operation or maintenance of the Aircraft
 by, or the business of, Lessee (or any Sublessee).  Upon receipt by Lessee
 of a written request from the Owner Participant specifying that the Owner
 Participant desires to have an authorized representative observe the next
 scheduled heavy maintenance visit to be performed on the Aircraft during
 the Term, Lessee shall cooperate with the Owner Participant to enable the
 Owner Participant's representative to observe such scheduled maintenance to
 be performed on the Aircraft during the Term; provided that the Owner
 Participant's authorized representative shall merely observe such scheduled
 heavy maintenance visit, shall not interfere with or extend in any manner
 the normal conduct or duration of the scheduled heavy maintenance visit,
 and shall not be entitled to direct any of the work performed in connection
 with such scheduled heavy maintenance visit.  Neither the Owner Participant
 nor the Indenture Trustee shall have any duty to make any such inspection
 nor shall either of them incur any liability or obligation by reason of not
 making such inspection.  Except during the final six (6) months of the Term
 or during the continuance of an Event of Default, all inspections by the
 Owner Participant and its authorized representatives or the Indenture
 Trustee and its authorized representatives provided for under this Section
 12 shall, in regard to each of the Owner Participant and the Indenture
 Trustee, be limited to one (1) inspection of any kind contemplated by this
 Section 12 during any calendar year.  During the last three months of the
 Term (unless Lessee shall have elected to purchase the Aircraft or renew
 this Lease in accordance with the terms of this Lease), with reasonable
 notice, Lessee will cooperate and cause any Sublessee to cooperate, at
 Lessor's sole cost, in all reasonable respects with the efforts of Lessor
 to sell or lease the Aircraft, including, without limitation, permitting
 prospective purchasers or lessees to inspect the Aircraft, any maintenance
 records relating to the Aircraft then required to be retained by the FAA or
 by the comparable government of registry of the Aircraft, all in accordance
 with the provisions set forth above; provided that any such cooperation
 shall not interfere with the normal operation or maintenance of the
 Aircraft by, or the business of, Lessee or any Sublessee.

        Section 13.   ASSIGNMENT.  Except as otherwise provided herein,
 Lessee will not, without prior written consent of Lessor, assign in whole
 or in part any of its rights or obligations hereunder.  Lessor agrees that
 it will not assign or convey its right, title and interest in and to this
 Lease or the Aircraft except as provided herein, in the Trust Indenture,
 the Trust Agreement, in the Participation Agreement or in any other
 Operative Document.  Subject to the foregoing, the terms and provisions of
 this Lease shall be binding upon and inure to the benefit of Lessor and
 Lessee and their respective successors and permitted assigns.

        Section 14.   EVENTS OF DEFAULT.  Each of the following events
 shall constitute an Event of Default (whether any such event shall be
 voluntary or involuntary or come about or be effected by operation of law
 or pursuant to or in compliance with any judgment, decree or order of any
 court or any order, rule or regulation of any administrative or
 governmental body) and each such Event of Default shall continue so long
 as, but only as long as, it shall not have been remedied:

        (a)  Lessee shall not have made (i) a payment of Basic Rent within
 five (5) Business Days after the same shall have become due, (ii) a payment
 of Termination Value within ten (10) Business Days after receipt by Lessee
 of written notice that the same is past due or (iii) an Advance when
 required to be made pursuant to Section 3(g) within five (5) Business Days
 after the same shall have been required to have been made; or

        (b)  Lessee shall have failed to make a payment of Supplemental
 Rent (other than Termination Value) after the same shall have become due
 and such failure shall continue for thirty (30) days after Lessee's receipt
 of written demand therefor by the party entitled thereto (provided that any
 failure to pay any amount owed by Lessee under the Tax Indemnity Agreement
 or any failure of Lessee to pay to Lessor or the Owner Participant when due
 any Excluded Payments shall not constitute an Event of Default unless
 notice is given by the Owner Participant to Lessee and the Indenture
 Trustee that such failure shall constitute an Event of Default); or

        (c)  Lessee shall have failed to perform or observe (or caused to
 be performed and observed) in any material respect any covenant or
 agreement (except the covenants set forth in the Tax Indemnity Agreement)
 to be performed or observed by it under any Operative Document, and such
 failure shall continue unremedied for a period of thirty (30) days after
 receipt by Lessee of written notice thereof from Lessor or the Indenture
 Trustee; provided, however, that if Lessee shall have undertaken to cure
 any such failure and, notwithstanding the diligence of Lessee in attempting
 to cure such failure, such failure is not cured within said thirty (30) day
 period but is curable with future due diligence, there shall exist no Event
 of Default under this Section 14 so long as Lessee is proceeding with due
 diligence to cure such failure and such failure is remedied not later than
 three hundred sixty (360) days after receipt by Lessee of such written
 notice; or

        (d)  any representation or warranty made by Lessee herein or in the
 Participation Agreement or any document or certificate furnished by Lessee
 in connection herewith or therewith or pursuant hereto or thereto (except
 the representations and warranties set forth in the Tax Indemnity Agreement
 and such documents or certificates as are furnished to the Owner
 Participant solely in connection with matters dealt with in the Tax
 Indemnity Agreement and for no other purpose and except for representations
 or warranties contained in the Pass Through Trust Agreement, the
 Underwriting Agreement or any document or instrument furnished pursuant to
 either thereof) shall prove to have been incorrect in any material respect
 at the time made, shall remain material at the time in question and such
 incorrectness shall not have been cured (to the extent of the adverse
 impact of such incorrectness on the interests of the Owner Participant,
 Lessor or the Note Holders) within thirty (30) days after the receipt by
 Lessee of a written notice from Lessor or the Indenture Trustee advising
 Lessee of the existence of such incorrectness; or

        (e)  the commencement of an involuntary case or other proceeding in
 respect of Lessee in an involuntary case under the federal bankruptcy laws,
 as now or hereafter constituted, or any other applicable federal or state
 bankruptcy, insolvency or other similar law in the United States or seeking
 the appointment of a receiver, liquidator, assignee, custodian, trustee,
 sequestrator (or similar official) of Lessee or for all or substantially
 all of its property, or seeking the winding-up or liquidation of its
 affairs and the continuation of any such case or other proceeding
 undismissed and unstayed for a period of ninety (90) consecutive days or an
 order, judgment or decree shall be entered in any proceeding by any court
 of competent jurisdiction appointing, without the consent of Lessee, a
 receiver, trustee or liquidator of Lessee, or of any substantial part of
 its property, or sequestering any substantial part of the property of
 Lessee and any such order, judgment or decree or appointment or
 sequestration shall be final or shall remain in force undismissed, unstayed
 or unvacated for a period of ninety (90) days after the date of entry
 thereof; or

        (f)  the commencement by Lessee of a voluntary case under the
 federal bankruptcy laws, as now constituted or hereafter amended, or any
 other applicable federal or state bankruptcy, insolvency or other similar
 law in the United States, or the consent by Lessee to the appointment of or
 taking possession by a receiver, liquidator, assignee, trustee, custodian,
 sequestrator (or other similar official) of Lessee or for all or
 substantially all of its property, or the making by Lessee of any
 assignment for the benefit of creditors, or Lessee shall take any corporate
 action to authorize any of the foregoing; or

        (g)  Lessee shall fail to carry and maintain on or with respect to
 the Aircraft (or cause to be carried and maintained) insurance required to
 be maintained in accordance with the provisions of Section 11 hereof;
 provided, however, that, notwithstanding anything to the contrary contained
 in Section 14(c) or (d) hereof, any failure of Lessee to perform or observe
 any covenant, condition, agreement or any error in a representation or
 warranty shall not constitute an Event of Default if such failure or error
 is caused solely by reason of an event that constitutes an Event of Loss so
 long as Lessee is continuing to comply with all of the terms of Section 10
 hereof.

        Section 15.   REMEDIES.  Upon the occurrence of any Event of
 Default and at any time thereafter so long as the same shall be continuing,
 Lessor may, at its option, declare by written notice to Lessee this Lease
 to be in default; and at any time thereafter, so long as any such
 outstanding Events of Default shall not have been remedied, Lessor may do
 one or more of the following with respect to all or any part of the
 Airframe and any or all of the Engines as Lessor in its sole discretion
 shall elect, to the extent permitted by, and subject to compliance with any
 mandatory requirements of, applicable law then in effect; provided,
 however, that during any period the Aircraft is subject to the Civil
 Reserve Air Fleet Program in accordance with the provisions of Section 7(b)
 hereof and in possession of the United States government or an agency or
 instrumentality of the United States, Lessor shall not, on account of any
 Event of Default, be entitled to do any of the following in such manner as
 to limit Lessee's control under this Lease (or any Sublessee's control
 under any Sublease) of any Airframe or any Engines installed thereon,
 unless at least sixty (60) days (or such lesser period as may then be
 applicable under the Air Mobility Command program of the United States
 Government) written notice of default hereunder shall have been given by
 Lessor by registered or certified mail to Lessee (and any Sublessee) with a
 copy addressed to the Contracting Office Representative for the Air
 Mobility Command of the United States Air Force under any contract with
 Lessee (or any Sublessee) relating to the Aircraft:

        (a)  upon the written demand of Lessor and at Lessee's expense,
 cause Lessee to return promptly, and Lessee shall return promptly, the
 Airframe or any Engine as Lessor may so demand to Lessor or its order in
 the manner and condition required by, and otherwise in accordance with all
 the provisions of, Section 5 as if such Airframe or Engine were being
 returned at the end of the Term, or Lessor, at its option, may enter upon
 the premises where all or any part of the Airframe or any Engine is located
 and take immediate possession of and remove the same by summary proceedings
 or otherwise (and/or, at Lessor's option, store the same at Lessee's
 premises until disposal thereof by Lessor), all without liability accruing
 to Lessor for or by reason of such entry or taking of possession or
 removing whether for the restoration of damage to property caused by such
 action or otherwise;

        (b)  sell the Airframe and/or any Engine at public or private sale,
 as Lessor may determine, or otherwise dispose of, hold, use, operate, lease
 to others or keep idle the Aircraft as Lessor, in its sole discretion, may
 determine, all free and clear of any rights of Lessee, except as
 hereinafter set forth in this Section 15;

        (c)  whether or not Lessor shall have exercised, or shall
 thereafter at any time exercise, any of its rights under paragraph (a) or
 paragraph (b) above with respect to the Airframe and/or any Engine, Lessor,
 by written notice to Lessee specifying a payment date which shall be the
 Rent Payment Date not earlier than ten (10) days from the date of such
 notice, may demand that Lessee pay to Lessor, and Lessee shall pay Lessor,
 on the payment date so specified, as liquidated damages for loss of a
 bargain and not as a penalty (in lieu of the installments of Basic Rent for
 the Aircraft due on Rent Payment Dates occurring on or after the Rent
 Payment Date specified as the payment date in such notice), any unpaid
 Basic Rent due on Rent Payment Dates prior to (but not on) the payment date
 so specified (including, without limitation, any adjustments to Basic Rent
 payable pursuant to Section 3(c)) plus whichever of the following amounts
 Lessor, in its sole discretion, shall specify in such notice (together with
 interest, if any, on such amount at the Past Due Rate from such specified
 payment date until the date of actual payment of such amount):  (i) an
 amount equal to the excess, if any, of the Termination Value for the
 Aircraft, computed as of the Rent Payment Date specified as the payment
 date in such notice, over the aggregate fair market rental value (computed
 as hereafter in this Section 15 provided) of such Aircraft for the
 remainder of the Term, after discounting such aggregate fair market rental
 value to present value as of the Rent Payment Date specified as the payment
 date in such notice at an annual rate equal to the Past Due Rate; or (ii)
 an amount equal to the excess, if any, of the Termination Value for such
 Aircraft, computed as of the Rent Payment Date specified as the payment
 date in such notice over the fair market sales value of such Aircraft
 (computed as hereafter in this Section provided) as of the Rent Payment
 Date specified as the payment date in such notice;

        (d)  in the event Lessor, pursuant to paragraph (b) above, shall
 have sold the Airframe and/or any Engine, Lessor, in lieu of exercising its
 rights under paragraph (c) above with respect to such Aircraft, may, if it
 shall so elect, demand that Lessee pay Lessor, and Lessee shall pay to
 Lessor, on the date of such sale, as liquidated damages for loss of a
 bargain and not as a penalty (in lieu of the installments of Basic Rent for
 the Aircraft due on or after such date), any unpaid Basic Rent with respect
 to the Aircraft due prior to (but not on) such date (including, without
 limitation, any adjustments to Basic Rent payable pursuant to Section 3(c))
 plus the amount of any deficiency between the net proceeds of such sale
 (after deduction of all reasonable costs of sale) and the Termination Value
 of such Aircraft, computed as of the Termination Value Date (as set forth
 on Exhibit C) on or immediately following the date of such sale together
 with interest, if any, on the amount of such deficiency, at the Past Due
 Rate, from the date of such sale to the date of actual payment of such
 amount; and/or

        (e)  Lessor may rescind this Lease as to the Aircraft, and/or may
 exercise any other right or remedy which may be available to it under
 applicable law or proceed by appropriate court action to enforce the terms
 hereof or to recover damages for breach hereof.

        For the purposes of paragraph (c) above, the "fair market rental
 value" or the "fair market sales value" of the Aircraft shall be the rental
 value or sales value, as the case may be, which would be obtained in an
 arm's-length transaction between an informed and willing lessee or
 purchaser, as the case may be, under no compulsion to lease or purchase, as
 the case may be, and an informed and willing lessor or seller in possession
 under no compulsion to lease, sell, as the case may be, in each case based
 upon the actual condition and location of the Aircraft, which value shall
 be determined by mutual agreement or, in the absence of mutual written
 agreement, pursuant to an appraisal prepared and delivered by a nationally
 recognized firm of independent aircraft appraisers nominated by Lessor, and
 Lessor shall immediately notify Lessee of such nomination.  Unless Lessee
 shall have objected in writing within ten (10) Business Days after its
 receipt of Lessor's notice, Lessor's nomination shall be conclusive and
 binding.  If Lessee shall object, however, Lessor and Lessee shall
 endeavor, within ten (10) Business Days after such objection is made, to
 select a mutually acceptable appraiser; provided that, if Lessee shall not
 so endeavor to make such selection, Lessor's nomination referred to in the
 preceding sentence hereof shall be conclusive and binding.  If Lessor and
 Lessee fail to reach agreement (except for the reason referred to in the
 proviso in the preceding sentence), or if any appraiser selected fails to
 act for any reason, then the question shall be determined by an appraisal
 (applying the definitions of "fair market rental value" and "fair market
 sales value" as set forth above based upon the actual condition of the
 Aircraft) mutually agreed to by two (2) recognized independent aircraft
 appraisers, one of which appraisers shall be chosen by Lessor and one by
 Lessee within five (5) Business Days after Lessor or Lessee shall have
 received written notice from the other party of a demand that such an
 appraisal be made, which notice shall specify the appraiser chosen by the
 party giving the notice or, if such appraisers cannot agree on the amount
 of such appraisal within twenty (20) Business Days after the end of such
 five (5) Business Day period, each shall render its own appraisal and shall
 by mutual consent choose another appraiser within five (5) Business Days
 after the end of such twenty (20) day period.  If, within such five (5) day
 period, such two appraisers fail to appoint a third appraiser, then either
 Lessor or Lessee, on behalf of both, may request such appointment by the
 then President of the Association of the Bar of the City of New York (or
 any successor organization thereto) or, in his absence, failure, refusal or
 inability to act, then either Lessor or Lessee may apply to the American
 Arbitration Association (or any successor organization thereto) in New
 York, New York for the appointment of such third appraiser.  The decision
 of the third appraiser so appointed shall be given within twenty (20)
 Business Days after the appointment of such third appraiser.  As soon as
 the third appraiser has delivered his appraisal, that appraisal shall be
 compared with the appraisals given by the other two (2) appraisers.  If the
 determination of one appraiser is more disparate from the average of all
 three determinations than each of the other two determinations, then the
 determination of such appraiser shall be excluded, the remaining two
 determinations shall be averaged and such average shall be final and
 binding upon the parties hereto.  If no determination is more disparate
 from the average of all three determinations than each of the other
 determinations, then such average shall be final and binding upon the
 parties thereto.  The cost of such appraisal or appointment shall be borne
 by Lessee.

        In addition, Lessee shall be liable, except as otherwise provided
 above and without duplication of amounts payable hereunder, for any and all
 unpaid Rent due hereunder before, after or during the exercise of any of
 the foregoing remedies (other than Basic Rent due on or after the payment
 referenced in paragraph (d) or paragraph (c) above) and for all reasonable
 legal fees and other costs and expenses (including fees of the appraisers
 hereinabove referred to) incurred by Lessor, the Indenture Trustee, the
 Loan Participants and the Owner Participant in connection with the return
 of the Airframe or any Engine in accordance with the terms of Section 5 or
 in placing such Airframe or Engine in the condition and airworthiness
 required by such Section.

        At any sale of the Aircraft or any part thereof pursuant to this
 Section 15, Lessor (or the Indenture Trustee, any Loan Participant or the
 Owner Participant) or Lessee may bid for and purchase such property.
 Lessor agrees to give Lessee at least fifteen (15) days prior written
 notice of the date fixed for any public sale of the Airframe or any Engine
 or of the date on or after which will occur the execution of any contract
 providing for any private sale and any such public sale shall be conducted
 in general so as to afford Lessee (and any Sublessee) a reasonable
 opportunity to bid.  Except as otherwise expressly provided above, no
 remedy referred to in this Section 15 is intended to be exclusive, but each
 shall be cumulative and in addition to any other remedy referred to above
 or otherwise available to Lessor at law or in equity; and the exercise or
 beginning of exercise by Lessor of any one or more of such remedies shall
 not preclude the simultaneous or later exercise by Lessor of any or all of
 such other remedies.  No waiver by Lessor of any Event of Default shall in
 any way be, or be construed to be, a waiver of any future or subsequent
 Event of Default.

        Section 16.   LESSEE'S COOPERATION CONCERNING CERTAIN MATTERS;
 DELIVERY OF FINANCIAL STATEMENTS.  Forthwith upon the execution and
 delivery of each Lease Supplement and Trust Supplement from time to time
 required by the terms hereof and upon the execution and delivery of any
 amendment to this Lease, to the Trust Indenture or to the Trust Agreement,
 Lessee will cause such Lease Supplement, Trust Supplement (and, in the case
 of the initial Lease Supplement and Trust Supplement, this Lease, the Trust
 Agreement and the Trust Indenture as well) or amendment to be duly filed
 and recorded, and maintained of record, in accordance with the applicable
 laws of the government of registry of the Aircraft.  In addition, Lessee
 will promptly and duly execute and deliver to Lessor such further documents
 and take such further action as Lessor or the Indenture Trustee may from
 time to time reasonably request in order more effectively to carry out the
 intent and purpose of this Lease and to establish and protect the rights
 and remedies created or intended to be created in favor of Lessor and the
 Indenture Trustee hereunder, including, without limitation, if requested by
 Lessor or the Indenture Trustee, at the expense of Lessee, the execution
 and delivery of supplements or amendments hereto or to the Trust Indenture,
 each in recordable form, subjecting to this Lease and the Trust Indenture,
 any airframe or engine substituted for the Airframe or any Engine pursuant
 to the terms thereof and the recording or filing of counterparts thereof,
 in accordance with the laws of such jurisdictions as Lessor or the
 Indenture Trustee may from time to time deem advisable.  Lessee agrees to
 furnish to Lessor and the Indenture Trustee promptly after execution and
 delivery of any supplement and amendment hereto and promptly after the
 execution and delivery of any supplement and amendment to the Trust
 Indenture (except for any such supplement or amendment which does not
 require or receive the approval of Lessee pursuant to the Operative
 Documents and is not required pursuant to the terms of the Operative
 Documents), an opinion of counsel (which may be Lessee's General Counsel,
 Deputy General Counsel, Associate General Counsel or Assistant General
 Counsel) reasonably satisfactory to Lessor and the Indenture Trustee as to
 the due recording or filing of such supplement or amendment.  Lessee will
 deliver to Lessor, the Owner Participant and the Indenture Trustee (a)
 within sixty (60) days after the end of each of the first three quarterly
 periods of each fiscal year of Lessee, the publicly filed Form 10-Q report
 of Lessee; and (b) within one hundred twenty (120) days after the close of
 such fiscal year, the publicly filed annual report and Form 10-K report of
 Lessee.

        Section 17.   NOTICES.  All notices required under the terms and
 provisions hereof shall be by telecopier or other telecommunication means
 (with such telecopy or other telecommunication means to be confirmed in
 writing), or if such notice is impracticable, by registered, first-class
 airmail, with postage prepaid, or by personal delivery of written notice
 and any such notice shall become effective when received, addressed:

        (a)  if to Lessee, for U.S. mail at 2345 Crystal Drive, Arlington,

 such other address or telecopy number as Lessee shall from time to time
 designate in writing to Lessor,

        (b)  if to Lessor, at 79 South Main Street, 3rd Floor, Salt Lake
 City, Utah 84111, Attention:  Corporate Trust Department (Telecopy No.

 shall from time to time designate in writing to Lessee, and

        (c)  if to a Loan Participant, the Indenture Trustee or the Owner
 Participant, addressed to such Loan Participant, the Indenture Trustee or
 the Owner Participant at such address or telecopy number as such Loan
 Participant, the Indenture Trustee or the Owner Participant shall have
 furnished by notice to Lessor and to Lessee, and, until an address is so
 furnished, addressed to such Loan Participant, the Indenture Trustee or the
 Owner Participant at its address or telecopy number set forth in Schedule I
 to the Participation Agreement.

        Section 18.   NO SET-OFF, COUNTERCLAIM, ETC.  All Rent shall be
 paid by Lessee to Lessor in funds of the type specified in Section 3(e).
 Except as expressly provided herein, Lessee's obligation to pay all Rent
 payable hereunder shall be absolute and unconditional and shall not be
 affected by any circumstance, including, without limitation, (i) any set-
 off, counterclaim, recoupment, defense or other right which Lessee may have
 against Lessor, in its individual capacity or as Owner Trustee under the
 Trust Agreement, the Indenture Trustee (in its individual capacity or as
 Indenture Trustee), any Loan Participant, the Owner Participant, or anyone
 else for any reason whatsoever (whether in connection with the transactions
 contemplated hereby or any other transactions), including, without
 limitation, any breach by Lessor or the Owner Participant of their
 respective warranties, agreements or covenants contained in any of the
 Operative Documents, (ii) any defect in the title, registration,
 airworthiness, condition, design, operation, or fitness for use of, or any
 damage to or loss or destruction of, the Aircraft, or any interruption or
 cessation in or prohibition of the use or possession thereof by Lessee (or
 any Sublessee) for any reason whatsoever, including, without limitation,
 any such interruption, cessation or prohibition resulting from the act of
 any government authority, (iii) any insolvency, bankruptcy, reorganization
 or similar case or proceedings by or against Lessee (or any Sublessee) or
 any other Person, or (iv) any other circumstance, happening, or event
 whatsoever, whether or not unforeseen or similar to any of the foregoing;
 provided, however, that notwithstanding the foregoing, Lessee shall be
 entitled to offset from any payment due to the Owner Participant the cost
 incurred by Lessee to discharge Lessor Liens relating to the Owner
 Participant.  If for any reason whatsoever this Lease shall be terminated
 in whole or in part by operation of law or otherwise except as specifically
 provided herein, Lessee nonetheless agrees without limitation of the other
 rights or remedies of Lessor hereunder to pay to Lessor an amount equal to
 each Rent payment at the time such payment would have become due and
 payable in accordance with the terms hereof had this Lease not been
 terminated in whole or in part.  Lessee hereby waives, to the extent
 permitted by applicable law, any and all rights which it may now have or
 which at any time hereafter may be conferred upon it, by statute or
 otherwise, to terminate, cancel, quit or surrender this Lease except in
 accordance with the express terms hereof.

        Section 19.   RENEWAL OPTIONS; PURCHASE OPTIONS; VALUATION.

        (a)  Renewal Options.

             (1) Fixed Renewal Term. Not more than 365 days and not less
      than one hundred twenty (120) days, before the end of the Basic Term
      or any Fixed Renewal Term (as hereinafter defined), Lessee may
      deliver to Lessor a written notice irrevocably electing to renew this
      Lease for a term having a duration and at a Basic Rent as determined
      below (any such renewal term, a "Fixed Renewal Term"). The duration
      of any Fixed Renewal Term shall be a period specified by Lessee
      before the end of the Basic Term which is (i) not less than one year
      (provided any such period shall be in six (6) month increments), (ii)
      not more than the longest period of time which would cause the Term,
      after giving effect to such Fixed Renewal Term, to be equal to 75% of
      the total useful life of the aircraft as determined by the Delivery
      Date appraisal. Each semi-annual installment of Basic Rent during the
      Fixed Renewal Term shall be equal to the lesser of (A) the fair
      market rental value of the Aircraft or (B) (I) one-half of the
      average annual Basic Rent during the Basic Term divided by (II) two
      (2).

             (2) Fair Market Renewal Term. Lessee shall have the right to
      renew this Lease for additional periods of one (1) year or more
      (provided any such period shall be on six (6) month increments)
      commencing at the end of the Basic Term or the Fixed Renewal Term for
      a Basic Rent equal to the fair market rental value of the Aircraft
      for such period (any such renewal term, a "Fair Market Renewal
      Term"). Each such option to renew shall be exercised by Lessee
      providing irrevocable notice at least one hundred twenty (120) days
      prior to the commencement of such Fair Market Renewal Term.

             (3) Waiver. If no written notice is delivered by Lessee to
      Lessor pursuant to Section 19(a)(1) or (a)(2) on or before the day
      specified therefor, Lessee shall be deemed to have waived any right
      to renew this Lease.

             (4) Conditions Precedent, Payment of Basic Rent. At the end of
      the Basic Term or any Renewal Term, if Lessee has elected to renew
      this Lease as aforesaid, (i) this Lease shall continue in full force
      and effect during the Renewal Term and (ii) Basic Rent for such
      Renewal Term shall be payable in semi-annual installments in arrears,
      each such installment being due and payable on each Rent Payment Date
      occurring during the Renewal Term, commencing with the Rent Payment
      Date immediately following the commencement of the Renewal Term,
      provided that Basic Rent for such Renewal Term shall be payable at
      such other frequency of payment consistent with the length of the
      Renewal Term as Lessor may reasonably designate in the event that
      such period is not divisible into whole semi-annual periods.

             (5) Termination Value. The amounts which are payable during
      any Renewal Term in respect of Termination Value with respect to the
      Aircraft shall be determined on the basis of the fair market sales
      value of the Aircraft as of the commencement of such Renewal Term,
      amortized on a straight-line basis over such Renewal Term to the
      projected fair market sales value of the Aircraft as of the
      expiration of such Renewal Term, as such fair market sales value in
      each case is determined prior to the commencement of such Renewal
      Term. In determining fair market sales value for purposes of
      calculating Termination Value for any Renewal Term effect shall be
      given to the encumbrance on the Aircraft of any Fixed Renewal Term
      available or in force.

        (b)  Purchase Options.  Lessee shall have the option, (i) upon at
 least thirty (30) days irrevocable prior written notice to Lessor prior to
 the EBO Date with respect to the purchase option set forth in clause (i)
 and (ii) upon at least one hundred twenty (120) days irrevocable prior
 written notice to Lessor prior to the relevant purchase date (each a
 "Purchase Option Date") with respect to the purchase options set forth in
 clauses (ii) and (iii), to terminate this Lease and to purchase the
 Aircraft:

             (1) on the EBO Date, for a purchase price equal to the EBO
      Amount set forth on Exhibit D, it being understood that if such
      amount is to be paid in installments, Lessee will, upon payment of
      the first installment of the EBO Amount, on the EBO date, receive
      title to the Aircraft free and clear of all liens (other than the
      Lien of the Indenture if Lessee has elected to assume the Equipment
      Notes in accordance with Section 7(u) of the Participation
      Agreement);

             (2) on the last Business Day of the Basic Term for a purchase
      price equal to the fair market sales value of the Aircraft on such
      date, provided, however, that in no event shall such purchase price
      exceed 50% of Lessor's Cost;

             (3) on the last Business Day of any Renewal Term for a
      purchase price equal to the fair market sales value of the Aircraft
      on such date.

        Notwithstanding the foregoing, but subject to the last sentence of
 this paragraph, the purchase price on any Purchase Option Date shall be
 sufficient, together with all other amounts payable simultaneously by
 Lessee, to pay in full the payments then required to be made on account of
 the principal amount of and accrued and unpaid interest on the Equipment
 Notes then outstanding.  Upon payment to Lessor in immediately available
 funds in Dollars of the full amount of the purchase price and payment of
 any other amounts then due hereunder (including all Rent and all reasonable
 costs or expenses of the Owner Participant in connection with such
 purchase), Lessor will transfer to Lessee, without recourse or warranty
 (except as to the absences of Lessor Liens), all of Lessor's right, title
 and interest in and to the Aircraft.  Notwithstanding the foregoing, Lessee
 may, in accordance with Section 7(u) of the Participation Agreement, assume
 the principal amount of the Equipment Notes then outstanding on any
 applicable Purchase Option Date in which event Lessee shall receive a
 credit against the purchase price otherwise payable pursuant to the
 preceding two sentences in an amount equal to the principal amount so
 assumed.

        (c)  Valuation.  At any time not earlier than three hundred sixty-
 five (365) days prior to the date on which Lessee may purchase the Aircraft
 pursuant to Section 19(b)(2) or (b)(3) hereof or renew this Lease pursuant
 to Section 19(a)(1) or (a)(2) hereof, Lessee may deliver to Lessor a
 revocable notice of its intent to exercise its renewal option or purchase
 option.  For all purposes of this Section 19 and Section 20, including the
 appraisal referred to in this Section 19(c), in determining "fair market
 rental value" or "fair market sales value", the Aircraft shall be valued
 (i) as if in the condition and otherwise in compliance with the terms of
 Section 5 upon a return of the Aircraft to Lessor and as if it had been
 maintained at all times as required in accordance with Section 7(a)(i)
 during periods when no Sublease was in effect, (ii) on the basis of the
 value which would obtain in an arm's-length transaction between an informed
 and willing buyer-user or lessee (other than a lessee or an Affiliate of a
 lessee currently in possession or a used equipment scrap dealer) under no
 compulsion to buy or lease and an informed and willing seller or lessor
 unaffiliated with such buyer-user or lessee and under no compulsion to sell
 or lease and disregarding the purchase and renewal options of the lessee
 provided in this Lease and (iii) in the case of such valuation for
 determining "fair market rental value", assuming such lessee would have
 substantially the same obligations during the Fair Market Renewal Term as
 provided hereunder including without limitation the obligations of Lessee
 to carry and maintain the insurance required by Section 11 hereof and to
 make certain payments with reference to Termination Value during the
 applicable Fair Market Renewal Term.  Upon receipt of such notice Lessor
 and Lessee shall confer in good faith with a view to reaching agreement on
 the "fair market rental value" or "fair market sales value" of the
 Aircraft.  If the parties have not so agreed within two hundred seventy
 (270) days prior to the end of the Basic Term or the Renewal Term in
 question, then the question shall be determined by an appraisal mutually
 agreed to by two recognized independent aircraft appraisers, one of which
 appraisers shall be chosen by Lessor and one by Lessee within five (5)
 Business Days after Lessor or Lessee shall have received written notice
 from the other party of a demand that such an appraisal be made, which
 notice shall specify the appraiser chosen by the party giving the notice
 or, if such appraisers cannot agree on the amount of such appraisal within
 twenty (20) Business Days after the end of such five (5) Business Day
 period, each shall render its own appraisal and shall by mutual consent
 choose another appraiser within five (5) Business Days after the end of
 such twenty (20) Business Day period.  If, within such five (5) Business
 Day period, such two appraisers fail to appoint a third appraiser, then
 either Lessor or Lessee, on behalf of both, may request such appointment by
 the then President of the Association of the Bar of the City of New York
 (or any successor organization thereto) or, in his absence, failure,
 refusal or inability to act, then either Lessor or Lessee may apply to the
 American Arbitration Association (or any successor organization thereto) in
 New York, New York for the appointment of such third appraiser.  The
 decision of the third appraiser so appointed shall be given within ten (10)
 Business Days after the appointment of such third appraiser.  As soon as
 the third appraiser has delivered his appraisal, that appraisal shall be
 compared with the appraisals given by the other two appraisers.  If the
 determination of one appraiser is more disparate from the average of all
 three determinations than each of the other two determinations, then the
 determination of such appraiser shall be excluded, the remaining two
 determinations shall be averaged and such average shall be final and
 binding upon the parties hereto.  If no determination is more disparate
 from the average of all three determinations than each of the other
 determinations, then such average shall be final and binding upon the
 parties thereto.  Lessee and Lessor shall share equally all expenses
 relating to such appraisal procedure provided if Lessee elects not to renew
 this Lease or purchase the Aircraft following such appraisal, Lessee shall
 pay all expenses of such appraisal.

        Section 20.   BURDENSOME PURCHASE OPTION.  If a Burdensome
 Termination Event shall have occurred, then on any Rent Payment Date
 occurring after the expiration of the Depreciation Period, Lessee shall
 have the option, upon at least one hundred twenty (120) days revocable
 prior notice to Lessor and, if any Equipment Notes are then outstanding,
 the Indenture Trustee, to purchase the Aircraft on such date for a purchase
 price equal to the higher of the Termination Value as of such date or the
 fair market sales value of the aircraft (determined as set forth in clause
 (c) above and excluding the value of any Significant Expenditure) (such
 price, the "Burdensome Buyout Price").  In addition, if on such date there
 shall be any Equipment Notes outstanding, Lessee shall have the option to
 assume, pursuant to Section 7(u) of the Participation Agreement and Section
 2.13 of the Trust Indenture, all of the obligations of Lessor under the
 Trust Indenture.  If such assumption is made, Lessee shall pay Lessor a
 purchase price equal to (I) the Burdensome Buyout Price minus (II) an
 amount equal to principal of, and accrued but unpaid interest on, any
 Equipment Notes that are outstanding on such date.  Upon such payment in
 full and payment of any other amounts then due hereunder (excluding any
 Basic Rent due on such date but including costs or expenses of the Owner
 Participant in connection with such purchase, any installments of Basic
 Rent due prior to such date and all unpaid Supplemental Rent due on or
 prior to such date), Lessor will transfer to Lessee, without recourse or
 warranty (except as to the absence of Lessor Liens), all of Lessor's right,
 title and interest in and to the Aircraft and under the Trust Indenture
 and, unless there shall be any Equipment Notes outstanding after such
 payment, exercise such rights as it has to cause the Aircraft to be
 released from the Lien of the Trust Indenture.

        Section 21.   SECURITY FOR LESSOR'S OBLIGATION TO HOLDERS OF
 EQUIPMENT NOTES.  In order to secure the indebtedness evidenced by the
 Equipment Notes, Lessor has agreed in the Trust Indenture, among other
 things, to assign to the Indenture Trustee this Lease, the Lease
 Supplements and any amendments to this Lease and to mortgage its interest
 in the Aircraft in favor of the Indenture Trustee, subject to the
 reservations and conditions therein set forth.  To the extent, if any, that
 this Lease, the Lease Supplements and any amendments to this Lease
 constitute chattel paper (as such term is defined in the Uniform Commercial
 Code as in effect in any applicable jurisdiction), no security interest in
 this Lease, the Lease Supplements and any amendments to this Lease may be
 created through the transfer or possession of any counterpart other than
 the original counterpart, which shall be identified as the counterpart
 containing the receipt therefor executed by the Indenture Trustee on the
 signature page thereof.  Lessee hereby accepts and consents to the
 assignment of all Lessor's right, title and interest in and to this Lease
 pursuant to the terms of the Trust Indenture.  Subject to Section 3(e)
 hereof, Lessee agrees to pay directly to the Indenture Trustee (or, after
 receipt by Lessee of notice from the Indenture Trustee of the discharge of
 the Trust Indenture, to Lessor), all amounts of Rent due or to become due
 hereunder and assigned to the Indenture Trustee and Lessee agrees that the
 Indenture Trustee's right to such payments hereunder shall be absolute and
 unconditional and shall not be affected by any circumstance, including,
 without limitation, the circumstances set forth in clauses (i) through (iv)
 of Section 18 hereof. Notwithstanding the foregoing assignment of this
 Lease, the obligations of Lessor to Lessee to perform the terms and
 conditions of this Lease shall remain in full force and effect.

        Section 22.   LESSOR'S RIGHT TO PERFORM FOR LESSEE.  If Lessee
 fails to make any payment of Rent required to be made by it hereunder or
 fails to perform or comply with any of its agreements contained herein,
 then (but in each case, except in the case of failure to pay Rent or in the
 case of failure to maintain insurance as required hereunder, no earlier
 than the fifteenth day after the occurrence of such failure, whether or not
 it shall yet constitute an Event of Default hereunder) Lessor may itself
 make such payment or perform or comply with such agreement but shall not be
 obligated hereunder to do so, and the amount of such payment and the amount
 of the reasonable expenses of Lessor incurred in connection with such
 payment or the performance of or compliance with such agreement, as the
 case may be, together with interest thereon at the Past Due Rate, shall be
 deemed Supplemental Rent, payable by Lessee upon demand.

        Section 23.   INVESTMENT OF SECURITY FUNDS; LIABILITY OF LESSOR
 LIMITED.

        (a)  Investment of Security Funds.  Any moneys held by Lessor as
 security hereunder for future payments to Lessee at a time when there is
 not continuing an Event of Default shall, until paid to Lessee, be invested
 by Lessor or, if the Trust Indenture shall not have been discharged, by the
 Indenture Trustee, as the case may be, as Lessee may from time to time
 direct in writing (and in absence of a written direction by Lessee, there
 shall be no obligation to invest such moneys) in Cash Equivalents.  There
 shall be promptly remitted to Lessee or its order (but no more frequently
 than monthly) any gain (including interest received) realized as a result
 of any such investment (net of any fees, commissions and other expenses, if
 any, incurred in connection with such investment) unless an Event of
 Default shall have occurred and be continuing.  Lessee shall be responsible
 for any net loss realized as a result of any such investment and shall
 reimburse Lessor (or the Indenture Trustee, as the case may be) therefor on
 demand.

        (b)  Liability of Lessor Limited.  It is expressly agreed and
 understood that all representations, warranties and undertakings of Lessor
 hereunder shall be binding upon Lessor only in its capacity as trustee
 under the Trust Agreement, and the institution acting as Lessor shall not
 be liable in its individual capacity for any breach thereof except for its
 gross negligence or willful misconduct or for breach of its covenants,
 representations and warranties contained herein, to the extent covenanted
 or made in its individual capacity.

        Section 24.   JURISDICTION.  Lessor and Lessee each hereby
 irrevocably submits itself to the non-exclusive jurisdiction of the United
 States District Court for the Southern District of New York and to the non-
 exclusive jurisdiction of the Supreme Court of the State of New York, New
 York County, for the purposes of any suit, action or other proceeding
 arising out of this Lease, the subject matter hereof or any of the
 transactions contemplated hereby brought by Lessor, Lessee, the Indenture
 Trustee, the Loan Participants or the Owner Participant or their successors
 or assigns.

        Section 25.   MISCELLANEOUS.  Any provision of this Lease 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, and
 any such prohibition or unenforceability in any jurisdiction shall not
 invalidate or render unenforceable such provision in any other
 jurisdiction.  No term or provision of this Lease may be changed, waived,
 discharged or terminated orally, but only by an instrument in writing
 signed by Lessor, Lessee and any assignee of Lessor's rights hereunder.
 This Lease shall constitute an agreement of lease, and nothing contained
 herein shall be construed as conveying to Lessee any right, title or
 interest in the Aircraft except as a lessee only.  Neither Lessee nor any
 affiliate of Lessee will file any tax returns in a manner inconsistent with
 the foregoing fact or with Lessor's ownership of the Aircraft.  The section
 and paragraph headings in this Lease and the table of contents are for
 convenience of reference only and shall not modify, define, expand or limit
 any of the terms or provisions hereof and all references herein to numbered
 sections, unless otherwise indicated, are to sections of this Lease.  THIS
 LEASE HAS BEEN DELIVERED IN THE STATE OF NEW YORK AND SHALL IN ALL RESPECTS
 BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF
 NEW YORK, INCLUDING ALL MATTERS OF CONSTRUCTION, VALIDITY AND PERFORMANCE.
 This Lease 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 26.   SUCCESSOR TRUSTEE.  Lessee agrees that in the case
 of the appointment of any successor Owner Trustee pursuant to the terms of
 the Trust Agreement, such successor Owner Trustee shall, upon written
 notice by such successor Owner Trustee, succeed to all the rights, powers
 and title of Lessor hereunder and shall be deemed to be Lessor and the
 owner of the Aircraft for all purposes hereof without the necessity of any
 consent or approval by Lessee (subject to Section 9 of the Participation
 Agreement) and without in any way altering the terms of this Lease or
 Lessee's obligations hereunder.  One such appointment and designation of a
 successor Owner Trustee shall not exhaust the right to appoint and
 designate further successor Owner Trustees pursuant to the Trust Agreement,
 but such right may be exercised repeatedly as long as this Lease shall be
 in effect.

        Section 27.   LEASE FOR U.S. FEDERAL INCOME TAX LAW PURPOSES;
 SECTION 1110 OF BANKRUPTCY CODE

        (a)  Lease for Federal Income Tax Law Purposes.  It is the intent
 of the parties to this Agreement that this Lease is a true lease for U.S.
 Federal income tax purposes.

        (b)  Section 1110 of Bankruptcy Code.  It is the intention of each
 of Lessee and Lessor that Lessor (and the Indenture Trustee as secured
 party and as assignee of Lessor under the Trust Indenture) shall be
 entitled to the benefits of Section 1110 of the Bankruptcy Code with
 respect to the right to take possession of the Aircraft, Airframe, Engines
 and Parts as provided in this Lease.


        IN WITNESS WHEREOF, Lessor and Lessee have each caused this Lease
 to be duly executed as of the day and year first above written.

 such term is defined in the Uniform Commercial Code as in effect in any
 applicable jurisdiction) no security interest in this Lease Supplement may
 be created through the transfer or possession of any counterpart other than
 the original executed counterpart, which shall be identified as the
 counterpart containing the receipt therefor executed by the Indenture
 Trustee on the signature page thereof.

      The portion of this Exhibit appearing below this will be intentionally
 deleted from the FAA filing counterpart as the parties hereto deem it to
 contain confidential information.

      Any recalculation of Basic Rent, Termination Value percentages and EBO
 Amount pursuant to the Lease shall be determined by the Owner Participant,
 and shall maintain the Owner Participant's Net Economic Return except as
 assumptions have been modified pursuant to Section 3 of the Lease or
 pursuant to the Tax Indemnity Agreement or the Participation Agreement, as
 the case may be; provided, however, that Lessee may request (A) Lessee's
 independent public accountants to verify such calculations but without any
 requirement that the Owner Participant disclose to such Persons the
 methodology and assumptions and (B) if Lessee believes that such
 calculations by the Owner Participant are in error then a nationally
 recognized firm of accountants selected by the Owner Participant and
 reasonably acceptable to Lessee shall be permitted to verify such
 calculations and the Owner Participant will make available to such firm
 (subject to the execution by such firm of a confidentiality agreement
 reasonably acceptable to the Owner Participant) the methodology and
 assumptions and any changes made therein pursuant to Section 3 of the
 Lease.  In the event of a verification under clause (B) of the first
 sentence of this paragraph the determination by such firm of accountants
 shall be final.  Lessee will pay the reasonable costs and expenses of the
 verification under clause (B) of the first sentence of this paragraph
 unless an error adverse to Lessee is established by such firm, and if as a
 result of such verification process the Basic Rent is adjusted and such
 adjustment causes the Net Present Value of Rents to decline by 10 (ten) or
 more basis points or causes a material reduction in Termination Value, EBO
 Amount or any indemnity payment (in which event the Owner Participant shall
 pay the reasonable costs and expenses of such verification process).  Such
 recalculated Basic Rent, Termination Value percentages and EBO amounts
 shall be set forth in a Lease Supplement or an amendment to the Lease.

      "Net Economic Return" means the Owner Participant's after-tax yield
 and aggregate after-tax cash flow utilizing the multiple investment sinking
 fund method of analysis, computed on the basis of the same methodology and
 assumptions as were utilized by the Owner Participant in determining Basic
 Rent, Termination Value percentages and EBO Amount as of the Delivery Date.

                             RETURN CONDITIONS


      The portion of this Exhibit appearing below this text will be
 intentionally deleted from the FAA filing counterpart as the parties hereto
 deem it to contain confidential information.

           (a)  Condition Upon Return. Unless purchased by Lessee pursuant
 to Section 19 or 20 hereof, upon the termination of this Lease at the end
 of the Basic Term or any Renewal Term or pursuant to Sections 9(b) or 15,
 unless Lessor has requested that Lessee return the Aircraft to a storage
 location pursuant to Section 5(b) (in which case the storage location
 provided in said Section 5(b) shall be deemed to be the return location),
 Lessee will return the Airframe to Lessor at one of Lessee's principal
 maintenance bases located in one of the forty-eight contiguous states of
 the United States chosen by Lessee, and Lessee will give Lessor at least
 ten (10) days prior written notice of the place of such return.  At the
 time of such return, (i) Lessee will, at its own cost and expense, unless
 otherwise requested by Lessor to retain the existing registration of the
 Aircraft at least ninety (90) days prior to the date of return hereunder,
 cause the Aircraft, if it is not then so registered, to be registered under
 the laws of the United States with the Federal Aviation Administration in
 the name of the Lessor or its designee, provided that Lessee shall be
 relieved of its obligations under this sentence if such registration is
 prohibited by reason of the failure of Lessor, Owner Participant or
 Lessor's designee to be eligible on such date to own an aircraft registered
 with the Federal Aviation Administration and (ii) the Airframe will be
 fully equipped with the Engines (or Acceptable Alternate Engines) installed
 thereon.  Also, at the time of such return, Lessor shall have good title to
 such Airframe and Engines or Acceptable Alternate Engines, and such
 Airframe and Engine or Acceptable Alternate Engines (A) shall be certified
 (or, if not then registered under the Transportation Code by reason of the
 proviso of clause (i) in the preceding sentence or because Lessor has so
 requested that the Aircraft not be so registered, shall hold a valid
 certificate of airworthiness issued by the country of registry and be
 eligible for certification by the Federal Aviation Administration) as an
 airworthy aircraft by the Federal Aviation Administration, (B) shall be
 free and clear of all Liens (other than Lessor Liens, Indenture Trustee's
 Liens and Loan Participant Liens) and rights of third parties under
 pooling, interchange, overhaul, repair or other similar agreements or
 arrangements, (C) shall be in a regular passenger configuration, and in as
 good a condition as when delivered by Seller to Lessee, ordinary wear and
 tear excepted, and otherwise in the condition required to be maintained
 under Lessee's FAA-approved maintenance plan (notwithstanding any Sublease
 theretofore in effect), (D) in the event that Lessee (or any Sublessee then
 in possession of the Aircraft) shall not then be using a continuous
 maintenance program with respect to the Airframe immediately prior to such
 return but instead shall have been using a block overhaul program with
 respect to the Airframe, then (i) such block overhaul program shall have
 been approved by the government of registry of the Aircraft and (ii) the
 Airframe shall have remaining until the next scheduled block overhaul at
 least 25% of the allowable hours between block overhauls permitted under
 the block overhaul program then used by Lessee or such Sublessee, (E) on
 average, the Engines or Acceptable Alternate Engines shall not have been
 operated since the last engine shop visit more than 75% of the time
 represented by Lessee's average on-wing hang time as then applicable to
 mature engines employed on A330-___ aircraft in Lessee's fleet (based on a
 three (3) year average), (F) shall have all Lessee's and any Sublessee's
 exterior marking removed or painted over with areas thereof refinished to
 match adjacent areas and (G) shall be in a state of cleanliness suitable
 under Lessee's normal service standards for operation in Lessee's revenue
 passenger service and in all such cases the Aircraft shall not have been
 discriminated against whether by reason of its leased status or otherwise
 in maintenance, use, operation or in any other manner whatsoever.

           If clause (D) of the first paragraph of this subsection (a) shall
 be applicable but the Airframe does not meet the conditions specified in
 said clause (D), Lessee shall pay or cause to be paid to Lessor,
 concurrently with the return thereof, a Dollar amount computed by
 multiplying (i) 110% of the direct cost to Lessee (based upon the direct
 cost to Lessee for similar aircraft in the fleet of Lessee) during the
 preceding 12 months of performing an airframe block overhaul of the type
 referred to in such clause (D) by (ii) a fraction of which (x) the
 numerator shall be the excess of 25% of the hours of operation allowable
 between such block overhauls over the actual number of hours of operation
 remaining on the Airframe to the next such block overhaul and (y) the
 denominator shall be the number of hours of operation allowable between
 such block overhauls in accordance with such block overhaul program.

           If the Engines (or Acceptable Alternate Engines) do not meet the
 conditions specified in clause (E) of the first paragraph of this
 subsection (a), Lessee shall pay or cause to be paid to Lessor,
 concurrently with the return thereof, a Dollar amount computed by
 multiplying (i) two (2) times (ii) 110% of the direct cost to Lessee (based
 upon the direct cost to Lessee for similar aircraft in the fleet of Lessee)
 during the preceding 12 months of performing for an engine of the same
 model as the Engines (or Acceptable Alternate Engines) the scheduled engine
 heavy maintenance under the maintenance program then used by Lessee for
 engines of the same model as the Engines (or Acceptable Alternate Engines)
 (such applicable amount, the "HEM Value") times (iii)25%, and subtracting
 from such product of clauses (i), (ii) and (iii), the value (as calculated
 in accordance with the following sentence) of the aggregate of the amount
 of time remaining to the next scheduled engine shop visit (determined by
 using Lessee's average on-wing hang time as then applicable to a mature
 engine of the type used on an A330-___ type aircraft (based on a three (3)
 year average)) for the Engines or Acceptable Alternate Engines.  The value
 of the time to the next scheduled shop visit for any Engine or Acceptable
 Alternate Engine shall be calculated by multiplying (i) a fraction of which
 (x) the numerator shall be the amount of time remaining until the next
 scheduled shop visit for such Engine or Acceptable Alternate Engine and (y)
 the denominator shall be the average on-wing hang time for such Engine or
 Acceptable Alternate Engine determined in accordance with the preceding
 sentence by (ii) HEM Value.

           (b)  Return of the Engines.  In the event that an Acceptable
 Alternate Engine shall be delivered with the returned Airframe as set forth
 in subsection (a) of this Exhibit G, Lessee, concurrently with such
 delivery, will, at no cost to Lessor, furnish, or cause to be furnished, to
 Lessor a full warranty (as to title) bill of sale with respect to each such
 Acceptable Alternate Engine, in form and substance satisfactory to Lessor
 (together with an opinion of counsel (which may be Lessee's General
 Counsel, Deputy General Counsel, Associate General Counsel or Assistant
 General Counsel) to the effect that such full warranty bill of sale has
 been duly authorized and delivered and is enforceable in accordance with
 its terms and that each such Acceptable Alternate Engine is free and clear
 of all Liens other than Lessor Liens, Loan Participant Liens and Indenture
 Trustee Liens), against receipt from Lessor of a bill of sale or evidencing
 the transfer, without recourse or warranty (except as to the absence of
 Lessor Liens), by Lessor to Lessee or its designee of all of Lessor's
 right, title and interest in and to any Engine not installed on the
 Airframe at the time of the return of the Airframe.

           (c)  Fuel and Manuals.  Upon the return of the Airframe upon any
 termination of this Lease in accordance with subsection (a) of this Exhibit
 G, (i) Lessor shall pay to Lessee, the amount of Lessee's cost for any fuel
 or oil contained in the fuel or oil tanks of such Airframe and (ii) Lessee
 shall deliver or cause to be delivered to Lessor all logs, manuals and data
 and inspection, modification and overhaul records required to be maintained
 under the provisions of the Lease.

 leased, and operated by Lessee (or, if a Sublease is then in effect, by
 Sublessee) of the same type as the Aircraft and (y) $300 million per
 occurrence, (B) of the type and covering the same risks as from time to
 time applicable to aircraft owned or leased and operated by Lessee of the
 same type as the Aircraft and (C) which is maintained in effect with
 insurers of nationally or internationally recognized reputation and
 responsibility; provided, however, that Lessee need not maintain such cargo
 liability insurance, or may maintain such cargo liability insurance in an
 amount less than $300 million per occurrence, so long as the amount of
 cargo liability insurance, if any, maintained with respect to the Aircraft
 is not less than the cargo liability insurance, if any, maintained for
 other Airbus Model A330 aircraft owned or leased and operated by Lessee.

           (2) During any period that the Airframe or an Engine, as the case
 may be, is on the ground and not in operation, Lessee may carry or cause to
 be carried as to such non-operating property, in lieu of the insurance
 required by clause (1) above, and subject to the self-insurance to the
 extent permitted by subsection (d) hereof, insurance by insurers of
 nationally or internationally recognized reputation and responsibility
 otherwise conforming with the provisions of said clause (1) except that (A)
 the amounts of coverage shall not be required to exceed the amounts of
 comprehensive airline liability from time to time applicable to property
 owned or leased by Lessee of the same type as such non-operating property
 and which is on the ground and not in operation; and (B) the scope of the
 risks covered and the type of insurance shall be the same as from time to
 time shall be applicable to aircraft owned or leased by Lessee of the same
 type as such non-operating property and which is on the ground and not in
 operation.

           (b)  Insurance Against Loss or Damage to the Aircraft.
 (1) Except as provided in clause (2) of this subsection (b), and subject to
 the provisions of subsection (d) of this Exhibit H permitting the self-
 insurance, Lessee shall maintain or cause to be maintained in effect, at
 its or any Sublessee's expense, with insurers of nationally or
 internationally recognized responsibility, all-risk aircraft hull insurance
 covering the Aircraft and fire and extended coverage and all-risk aircraft
 hull insurance covering Engines and Parts while temporarily removed from
 the Aircraft and not replaced by similar components; provided that such
 insurance shall at all times while the Aircraft is subject to this Lease be
 for an amount (taking into account the self-insurance to the extent
 permitted by subsection (d) of this Exhibit H) not less than the
 Termination Value for the Aircraft; provided further, that, subject to
 compliance with subsection (d) of this Exhibit H, such all-risk property
 damage insurance covering Engines and Parts temporarily removed from an
 Airframe or an airframe or (in the case of Parts) an Engine need be
 obtained only to the extent available at reasonable cost (as reasonably
 determined by Lessee).  In the case of a Loss with respect to an engine
 (other than an Engine) installed on the airframe in circumstances which do
 not constitute an Event of Loss with respect to the Airframe, Lessor shall
 promptly remit any payment made to it of any insurance proceeds in respect
 of such Loss to Lessee or any other third party that is entitled to receive
 such proceeds.

           Unless an Event of Default has occurred and is continuing, all
 losses will be adjusted by Lessee with the insurers.  As between Lessor and
 Lessee, it is agreed that all insurance payments received as the result of
 the occurrence of an Event of Loss will be applied as follows:

                (x)  if such payments are received with respect to the
           Airframe (or the Airframe and the Engines installed thereon), (i)
           unless such property is replaced pursuant to the last paragraph
           of Section 10(a), so much of such payments remaining, after
           reimbursement of Lessor (as provided in Section 7.01 of the Trust
           Agreement) and the Owner Participant for reasonable costs and
           expenses, as shall not exceed the Termination Value and the other
           amounts payable pursuant to Section 10(a) hereof shall be applied
           in reduction of Lessee's obligation to pay such Termination Value
           and other amounts payable pursuant to Section 10(a) hereof, if
           not already paid by Lessee, or, if already paid by Lessee, shall
           be applied to reimburse Lessee for its payment of such
           Termination Value and such other amounts payable, and the
           balance, if any, of such payments remaining thereafter will be
           paid over to, or retained by, Lessee (or if directed by Lessee,
           any Sublessee); or (ii) if such property is replaced pursuant to
           the last paragraph of Section 10(a), such payments shall be paid
           over to, or retained by, Lessee (or if directed by Lessee, any
           Sublessee), provided that Lessee shall have fully performed or,
           concurrently therewith, will fully perform the terms of the last
           paragraph of Section 10(a) with respect to the Event of Loss for
           which such payments are made; and

                (y)  if such payments are received with respect to an Engine
           under the circumstances contemplated by Section 10(b) hereof, so
           much of such payments remaining after reimbursement of Lessor (as
           provided in Section 7.01 of the Trust Agreement) and the Owner
           Participant for reasonable costs and expenses, shall be paid over
           to, or retained by, Lessee (or if directed by Lessee, any
           Sublessee), provided that Lessee shall have fully performed or
           concurrently therewith will fully perform the terms of Section
           10(b) with respect to the Event of Loss for which such payments
           are made.

           As between Lessor and Lessee, the insurance payments for any
 property damage loss to the Airframe or any engine not constituting an
 Event of Loss with respect thereto will be applied in payment for repairs
 or for replacement property in accordance with the terms of Sections 7 and
 8, if not already paid for by Lessee (or any Sublessee), and any balance
 (or if already paid for by Lessee (or any Sublessee), all such insurance
 proceeds) remaining after compliance with such Sections with respect to
 such loss shall be paid to Lessee (or any Sublessee if directed by Lessee).

           (2)  During any period that the Aircraft is on the ground and not
 in operation, Lessee may carry or cause to be carried, in lieu of the
 insurance required by clause (1) above, and subject to self-insurance to
 the extent permitted by subsection (d) of this Exhibit H, insurance
 otherwise conforming with the provisions of said clause (1) except that the
 scope of the risks and the type of insurance shall be the same as from time
 to time applicable to aircraft owned or leased by Lessee (or, if a Sublease
 is then in effect, by Sublessee) of the same type as the Aircraft similarly
 on the ground and not in operation, provided that, subject to self-
 insurance to the extent permitted by subsection (d) of this Exhibit H,
 Lessee shall maintain insurance against risk of loss or damage to the
 Aircraft in an amount at least equal to the Termination Value of the
 Aircraft during such period that the Aircraft is on the ground and not in
 operation.

           (3)  If Lessee (or any Sublessee) shall at any time operate or
 propose to operate the Aircraft, Airframe or any Engine (i) in any area of
 recognized hostilities or (ii) on international routes, and war-risk,
 hijacking or allied perils insurance is maintained by Lessee (or any
 Sublessee) with respect to other aircraft owned and operated by Lessee (or
 any Sublessee) on such routes or in such areas, Lessee shall maintain or
 cause to be maintained war-risk, hijacking and related perils insurance of
 substantially the same type carried by major United States commercial air
 carriers operating the same or comparable models of aircraft on similar
 routes or in such areas and in no event in an amount less than the
 Termination Value.

           (c)  Reports, etc.  Lessee will furnish, or cause to be
 furnished, to Lessor, the Indenture Trustee, the Owner Participant and the
 Pass Through Trustee, on or before the Delivery Date and on each annual
 anniversary date of Lessee's applicable insurance, a report, signed by
 Lessee's regular insurance broker or any other independent firm of
 insurance brokers reasonably acceptable to Lessor which brokers may be in
 the regular employ of Lessee (the "Insurance Brokers"), describing in
 reasonable detail the hull and liability insurance (and property insurance
 for detached engines and parts) then carried and maintained with respect to
 the Aircraft and stating the opinion of such firm that the insurance
 complies with the terms hereof; provided, that all information contained in
 the foregoing report shall not be made available by Lessor, the Indenture
 Trustee or the Owner Participant or the Pass Through Trustee to anyone
 except (i) to prospective and permitted transferees of Lessor's, the Owner
 Participant's, the Indenture Trustee's or the Pass Through Trustee's
 interest or their respective counsel, independent certified public
 accountants and independent insurance brokers or other agents, who agree to
 hold such information confidential, (ii) to Lessor's, the Owner
 Participant's, the Indenture Trustee's or a Pass Through Trustee's counsel
 or independent certified public accountants, independent insurance brokers
 or agents who agree to hold such information confidential or (iii) as may
 be required by any statute, court or administrative order or decree or
 governmental ruling or regulation; provided, however that any disclosure
 permitted by clause (iii) above shall be made only to the extent necessary
 to meet the specific requirements or needs of the Persons to whom such
 disclosures are hereby permitted.  Lessee will cause such Insurance Broker
 to agree to advise Lessor, the Indenture Trustee, the Owner Participant and
 the Pass Through Trustee in writing of any act or omission on the part of
 Lessee of which it has knowledge and which might invalidate or render
 unenforceable, in whole or in part, any insurance on the Aircraft and to
 advise in writing at least thirty (30) days (ten (10) days in the case of
 war risk and allied perils coverage and ten (10) days notice with respect
 to the Electronic Date Recognition Exclusion Limited Coverage Endorsement),
 prior to the cancellation or material adverse change of any insurance
 maintained pursuant to Section 11, provided that if the notice period
 specified above is not reasonably obtainable, the Insurance Broker shall
 provide for as long a period of prior notice as shall then be reasonably
 obtainable.  In addition, Lessee will also cause such Insurance Brokers to
 deliver to Lessor, the Indenture Trustee, the Owner Participant and the
 Pass Through Trustee, on or prior to the date of expiration of any
 insurance policy referenced in a previously delivered certificate of
 insurance, a new certificate of insurance, substantially in the same form
 as delivered by Lessee to such parties on the Delivery Date except for such
 changes in the report or the coverage consistent with the terms hereof.  In
 the event that Lessee or any Sublessee shall fail to maintain or cause to
 be maintained insurance as herein provided, Lessor or the Indenture Trustee
 may at its sole option, but shall be under no duty to, provide such
 insurance and, in such event, Lessee shall, upon demand, reimburse Lessor
 or the Indenture Trustee, as Supplemental Rent, for the cost thereof to
 Lessor or the Indenture Trustee, as the case may be; provided, however,
 that no exercise by Lessor or the Indenture Trustee, as the case may be, of
 said option shall affect the provisions of this Lease, including the
 provisions of Section 14(g).

           (d)  Self-Insurance.  Lessee may self-insure by way of
 deductible, premium adjustment or franchise provisions or otherwise
 (including, with respect to insurance maintained pursuant to subsection (b)
 of this Exhibit H, insuring for an amount that is less than the Termination
 Value of the Aircraft) the risks required to be insured against pursuant to
 Section 11 under a program applicable to all aircraft (whether owned or
 leased) in Lessee's fleet, but in no case shall the aggregate amount of
 self-insurance in regard to subsection (a) and (b) of this Exhibit H exceed
 for any policy year, with respect to all of the aircraft (whether owned or
 leased) in Lessee's fleet (including, without limitation, the Aircraft),
 the lesser of (i) 50% of the highest replacement value of any single
 aircraft in Lessee's fleet or (ii) 1-1/2% of the average aggregate
 insurable value (during the preceding policy year) of all aircraft
 (including, without limitation, the Aircraft) on which Lessee carries
 insurance, unless an insurance broker of national standing shall certify
 that the standard among all other major United States airlines is a higher
 level of self-insurance, in which case Lessee may insure the Aircraft to
 such higher level.  In addition to the foregoing right to self-insure,
 Lessee (and any Sublessee) may self-insure to the extent of any applicable
 mandatory minimum per aircraft (or, if applicable, per annum or other
 period) hull or liability insurance deductible customary in the airline
 industry imposed by the aircraft hull or liability insurer.

           (e)  Terms of Policies.  Any policies of insurance carried in
 accordance with subsection (a) or (b) of this Exhibit H and any policies
 taken out in substitution or replacement for any of such policies (A) shall
 be amended to name the Additional Insureds as their respective interests
 may appear, (B) may provide for the self-insurance to the extent permitted
 in subsection (d) of this Exhibit H, (C) shall provide that if the insurers
 cancel such insurance for any reason whatever or if any material change is
 made in such insurance which adversely affects the interest of the
 Additional Insureds, or such insurance shall lapse for non-payment of
 premium, such cancellation, lapse or change shall not be effective as to
 the Additional Insureds for thirty (30) days (ten (10) days in the case of
 war risk and allied perils coverage and ten (10) days in the case of the
 Electronic Date Recognition Limited Coverage Endorsement) after issuance to
 the Additional Insureds, respectively, of written notice by such insurers
 of such cancellation, lapse or change; provided, however, that if any
 notice period specified above is not reasonably obtainable, such policies
 shall provide for as long a period of prior notice as shall then be
 reasonably obtainable, (D) shall provide that in respect of the respective
 interests of the Additional Insureds in such policies the insurance shall
 not be invalidated by any action or inaction of Lessee (or, if any Sublease
 is then in effect, any Sublessee) or any other Person and shall insure the
 Additional Insureds regardless of any breach or violation of any warranty,
 declaration or condition contained in such policies by Lessee (or, if any
 Sublease is then in effect, any Sublessee), (E) shall be primary without
 right of contribution from any other insurance which is carried by any
 Additional Insured, (F) shall expressly provide that all of the provisions
 thereof, except the limits of liability, shall operate in the same manner
 as if there were a separate policy covering each insured, (G) shall waive
 any right of the insurers to any set-off or counterclaim or any other
 deduction, whether by attachment or otherwise, in respect of any liability
 of any Additional Insured to the extent of any moneys due to any Additional
 Insured and (H) shall provide that (i) in the event of a loss involving
 proceeds in excess of $5,000,000, the proceeds in respect of such loss up
 to an amount equal to the Termination Value for the Aircraft shall be
 payable to Lessor (or, so long as the Trust Indenture shall not have been
 discharged, the Indenture Trustee) (except in the case of a loss with
 respect to an Engine installed on an airframe other than the Airframe, in
 which case Lessee (or any Sublessee) shall arrange for any payment of
 insurance proceeds in respect of such loss to be held for the account of
 Lessor (or, so long as the Trust Indenture shall not have been discharged,
 the Indenture Trustee) whether such payment is made to Lessee (or any
 Sublessee) or any third party), it being understood and agreed that in the
 case of any payment to Lessor (or the Indenture Trustee) otherwise than in
 respect of an Event of Loss, Lessor (or the Indenture Trustee) shall, upon
 receipt of evidence satisfactory to it that the damage giving rise to such
 payment shall have been repaired or that such payment shall then be
 required to pay for repairs then being made, pay the amount of such payment
 (and all earnings thereon) to Lessee or its order and (ii) the entire
 amount of any loss involving proceeds of $5,000,000 or less or the amount
 of any proceeds of any loss in excess of the Termination Value for the
 Aircraft shall be paid to Lessee or its order unless an Event of Default
 shall have occurred and be continuing and the insurers have been notified
 thereof by Lessor or the Indenture Trustee.

  Indenture and the rights of the Owner Trustee and the Owner Participant
  hereunder.

            Concurrently with the delivery hereof, the Owner Trustee is
  delivering to the Indenture Trustee the original executed counterpart of
  the Lease and the Lease Supplement No. 1 (to each of which a chattel
  paper receipt is attached), and executed copies of the Participation
  Agreement, the French Pledge Agreement and the Purchase Agreement
  Assignment with the Consent and Agreement attached thereto.

            TO HAVE AND TO HOLD all and singular the aforesaid property
  unto the Indenture Trustee, and its successors and assigns, in trust for
  the benefit and security of the Note Holders, the Loan Participants and
  the Indenture Indemnitees except as provided in Section 2.15 and Article
  III hereof without any preference, distinction or priority of any one
  Equipment Note over any other by reason of priority of time of issue,
  sale, negotiation, date of maturity thereof or otherwise for any reason
  whatsoever, and for the uses and purposes and in all cases and as to all
  property specified in paragraphs (1) through (7) inclusive above, subject
  to the terms and provisions set forth in this Trust Indenture.

            It is expressly agreed that anything herein contained to the
  contrary notwithstanding, the Owner Trustee shall remain liable under
  each of the Indenture Agreements to which it is a party to perform all of
  the obligations assumed by it thereunder, except to the extent prohibited
  or excluded from doing so pursuant to the terms and provisions thereof,
  and the Loan Participants, Indenture Indemnitees, Indenture Trustee and
  the Note Holders shall have no obligation or liability under the
  Indenture Agreements, by reason of or arising out of the assignment
  hereunder, nor shall the Loan Participants, Indenture Indemnitees,
  Indenture Trustee or the Note Holders be required or obligated in any
  manner to perform or fulfill any obligations of the Owner Trustee under
  or pursuant to any of the Indenture Agreements to which it is a party,
  or, except as herein expressly provided, to make any payment, or to make
  any inquiry as to the nature or sufficiency of any payment received by
  it, or present or file any claim, or take any action to collect or
  enforce the payment of any amounts which may have been assigned to it or
  to which it may be entitled at any time or times.

            Notwithstanding the above, the Indenture Trustee agrees, for
  the benefit of AVSA, S.A.R.L., that in exercising or assigning its rights
  under the Purchase Agreement Assignment, the terms and conditions of the
  Purchase Agreement Assignment shall apply to, and be binding upon, the
  Indenture Trustee.

            The Owner Trustee does hereby constitute the Indenture Trustee
  the true and lawful attorney of the Owner Trustee, irrevocably, granted
  for good and valuable consideration and coupled with an interest and with
  full power of substitution, and with full power (in the name of the Owner
  Trustee or otherwise) to ask for, require, demand, receive, compound and
  give acquittance for any and all monies and claims for monies (in each
  case including insurance and requisition proceeds but in all cases
  excluding Excluded Payments) due and to become due under or arising out
  of the Indenture Agreements, and all other property which now or
  hereafter constitutes part of the Trust Indenture Estate, to endorse any
  checks or other instruments or orders in connection therewith and to file
  any claims or to take any action or to institute any proceedings which
  the Indenture Trustee may deem to be necessary or advisable in the
  premises. Without limiting the generality of the foregoing, but subject
  to the rights of the Owner Trustee and the Owner Participant hereunder,
  during the continuance of any Event of Default under this Trust
  Indenture, the Indenture Trustee shall have the right under such power of
  attorney to accept any offer in connection with the exercise of remedies
  as set forth herein of any purchaser to purchase the Airframe and Engines
  and upon such purchase to execute and deliver in the name of and on
  behalf of the Owner Trustee an appropriate bill of sale and other
  instruments of transfer relating to the Airframe and Engines, when
  purchased by such purchaser, and to perform all other necessary or
  appropriate acts with respect to any such purchase, and in its discretion
  to file any claim or take any other action or proceedings, either in its
  own name or in the name of the Owner Trustee or otherwise, which the
  Indenture Trustee may deem necessary or appropriate to protect and
  preserve the right, title and interest of the Indenture Trustee in and to
  such Rents and other sums and the security intended to be afforded
  hereby; provided, however, that no action of the Indenture Trustee
  pursuant to this paragraph shall increase the obligations or liabilities
  of the Owner Trustee to any Person beyond those obligations and
  liabilities specifically set forth in this Trust Indenture and in the
  other Operative Documents.  Under the Lease, Lessee is directed, so long
  as this Trust Indenture shall not have been fully discharged, to make all
  payments of Rent (other than Excluded Payments) and all other amounts
  which are required to be paid to or deposited with the Owner Trustee
  pursuant to the Lease (other than Excluded Payments) directly to, or as
  directed by, the Indenture Trustee at such address or addresses as the
  Indenture Trustee shall specify, for application as provided in this
  Trust Indenture.  The Owner Trustee agrees that promptly upon receipt
  thereof, it will transfer to the Indenture Trustee any and all monies
  from time to time received by it constituting part of the Trust Indenture
  Estate, for distribution by the Indenture Trustee pursuant to this Trust
  Indenture, except that the Owner Trustee shall accept for distribution
  pursuant to the Trust Agreement any amounts distributed to it by the
  Indenture Trustee under this Trust Indenture.

            The Owner Trustee agrees that at any time and from time to
  time, upon the written request of the Indenture Trustee, the Owner
  Trustee will promptly and duly execute and deliver or cause to be duly
  executed and delivered any and all such further instruments and documents
  as the Indenture Trustee may reasonably deem necessary or desirable to
  perfect, preserve or protect the mortgage, security interests and
  assignments created or intended to be created hereby or to obtain for the
  Indenture Trustee the full benefits of the assignment hereunder and of
  the rights and powers herein granted.  The parties hereto acknowledge
  that neither the Owner Trustee nor the Owner Participant shall have any
  obligation as to any recording, filing, refiling or re-recording of any
  documents or instruments in regard to maintaining the perfection of the
  security interests created hereunder, in the Trust Indenture Estate or
  any security interest that may be claimed to have been created by the
  Lease or the ownership interest of the Owner Trustee in the Aircraft.

            The Owner Trustee does hereby warrant and represent that it has
  not assigned or pledged, and hereby covenants and agrees that it will not
  assign or pledge, so long as the assignment hereunder shall remain in
  effect, and the Lien hereof shall not have been released pursuant to
  Section 10.01 hereof, any of its right, title or interest hereby
  assigned, to anyone other than the Indenture Trustee, and that it will
  not, except as otherwise provided in this Trust Indenture and except with
  respect to Excluded Payments to which it is entitled, (i) accept any
  payment from Lessee under any Indenture Agreement, (ii) enter into any
  agreement amending or supplementing any Indenture Agreement, (iii)
  execute any waiver or modification of, or consent under, the terms of, or
  exercise any rights, powers or privileges under, any Indenture Agreement,
  (iv) settle or compromise any claim (other than those relating to an
  Excluded Payment) arising under any Indenture Agreement or (v) submit or
  consent to the submission of any dispute, difference or other matter
  arising under or in respect of any Indenture Agreement to arbitration
  thereunder.

            The Owner Trustee does hereby further agree that it will not
  without the written consent of the Indenture Trustee:

            (a)  collect or agree to the receipt or collection of any
                 payment of Rent (other than Excluded Payments), including
                 Basic Rent, EBO Amount, Termination Value or any other
                 payment to be made pursuant to Section 9, 10, 19 or 20 of
                 the Lease prior to the date for the payment thereof
                 provided for by the Lease or assign, transfer or
                 hypothecate (other than to the Indenture Trustee
                 hereunder) any payment of Rent (other than Excluded
                 Payments), including Basic Rent, EBO Amount, Termination
                 Value or any other payment to be made pursuant to Section
                 9, 10, 19 or 20 of the Lease, then due or to accrue in the
                 future under the Lease in respect of the Airframe and
                 Engines; or

            (b)  except as contemplated by the Trust Agreement in
                 connection with the appointment of a successor owner
                 trustee, sell, mortgage, transfer, assign or hypothecate
                 (other than to the Indenture Trustee hereunder) its
                 interest in the Airframe and Engines or any part thereof
                 or in any amount to be received by it from the use or
                 disposition of the Airframe and Engines, other than
                 amounts distributed to it pursuant to Article III hereof.

            It is hereby further agreed that any and all property described
  or referred to in the granting clauses hereof which is hereafter acquired
  by the Owner Trustee shall ipso facto, and without any further
  conveyance, assignment or act on the part of the Owner Trustee or the
  Indenture Trustee, become and be subject to the Lien herein granted as
  fully and completely as though specifically described herein, but nothing
  contained in this paragraph shall be deemed to modify or change the
  obligations of the Owner Trustee contained in the foregoing paragraphs.

            The Owner Trustee does hereby ratify and confirm the Lease and
  does hereby agree that it will not violate any covenant or agreement made
  by it therein, herein or in any of the other Owner Trustee Documents.

            Notwithstanding the Granting Clause or any of the foregoing
  paragraphs, there is hereby excluded from the foregoing sale, transfer,
  assignment, grant, pledge and security interest all Excluded Payments.

            IT IS HEREBY COVENANTED AND AGREED by and between the parties
  hereto as follows:

  overdue interest and any other amounts payable hereunder which are
  overdue, in each case for the period the same is overdue.  Amounts shall
  be overdue if not paid when due (whether at stated maturity, by
  acceleration or otherwise).

          The holder hereof, by its acceptance of this Equipment Note agrees
  that as between it and the Owner Trustee, except as expressly provided in

          The Principal Amount and interest and other amounts due hereunder
  shall be payable in Dollars in immediately available funds at the
  Corporate Trust Office of the Indenture Trustee, or as otherwise provided
  in the Trust Indenture.  Each such payment shall be made on the date such
  payment is due and without any presentment or surrender of this Equipment
  Note, except that in the case of any final payment with respect to this
  Equipment Note, the Equipment Note shall be surrendered promptly
  thereafter to the Indenture Trustee for cancellation.

          The holder hereof, by its acceptance of this Equipment Note,
  agrees that, except as provided in the Trust Indenture, each payment of
  an installment of the Principal Amount, Make-Whole Amount, if any, and
  interest received by it hereunder shall be applied, first, to the payment
  of accrued interest on this Equipment Note (as well as any interest on
  any overdue Principal Amount, any overdue Make-Whole Amount, if any, or,
  to the extent permitted by Law, any overdue interest and other amounts
  hereunder) to the date of such payment, second, to the payment of the
  Principal Amount of this Equipment Note (or portion hereof) then due
  (other than by reason of redemption), third, to the payment of Make-Whole
  Amount, if any, and any other amount due hereunder or under the Trust
  Indenture, and fourth, the balance, if any, remaining thereafter, to the
  payment of the Principal Amount hereof  remaining unpaid and due by
  reason of redemption.  The amounts paid pursuant to clause fourth of the
  preceding sentence shall be applied to installments of the Principal
  Amount of this Equipment Note remaining unpaid in the inverse order of
  their normal maturity.

          This Equipment Note is one of the Equipment Notes referred to in
  the Trust Indenture which have been or are to be issued by the Owner
  Trustee pursuant to the terms of the Trust Indenture.  The Trust
  Indenture Estate is held by the Indenture Trustee as security, in part,
  for the Equipment Notes.  The provisions of this Equipment Note are
  subject to the Trust Indenture.  Reference is hereby made to the Trust
  Indenture and the Participation Agreement for a complete statement of the
  rights and obligations of the holder of, and the nature and extent of the
  security for, this Equipment Note and the rights and obligations of the
  holders of, and the nature and extent of the security for, any other
  Equipment Notes executed and delivered under the Trust Indenture, as well
  as for a statement of the terms and conditions of the Trust created by
  the Trust Indenture, to all of which terms and conditions in the Trust
  Indenture and the Participation Agreement each holder hereof agrees by
  its acceptance of this Equipment Note.

          As provided in the Trust Indenture and subject to certain
  limitations therein set forth, this Equipment Note is exchangeable for a
  like aggregate Principal Amount of Equipment Notes of different
  authorized denominations, as requested by the holder surrendering the
  same.

          Prior to the due presentment for registration of transfer of this
  Equipment Note, the Owner Trustee and the Indenture Trustee shall deem
  and treat the Person in whose name this Equipment Note is registered on
  the Equipment Note Register as the absolute owner and holder hereof for
  the purpose of receiving all amounts payable with respect to this
  Equipment Note and for all purposes, and neither of the Owner Trustee nor
  the Indenture Trustee shall be affected by notice to the contrary.

          This Equipment Note is subject to redemption as provided in
  Sections 2.10 [, 2.11](1) and 2.12 of the Trust Indenture but not
  otherwise.  This Equipment Note is also subject to assumption by Lessee
  as provided in Section 2.13 of the Trust Indenture, to exchange and to
  purchase by the Owner Participant or the Owner Trustee as provided in
  Section 2.14 of the Trust Indenture but not otherwise.

          [The indebtedness evidenced by this Equipment Note is, to the
  extent and in the manner provided in the Trust Indenture, subordinate and
  subject in right of payment to the prior payment in full of the Secured
  Obligations (as defined in the Trust Indenture) in respect of Series G
  Equipment Notes, and this Equipment Note is issued subject to such
  provisions.  The Note Holder of this Equipment Note, by accepting the
  same, (a) agrees to and shall be bound by such provisions, (b) authorizes
  and directs the Indenture Trustee on its behalf to take such action as
  may be necessary or appropriate to effectuate the subordination as
  provided in the Trust Indenture and (c) appoints the Indenture Trustee
  its attorney-in-fact for such purpose.](2)

  Payment Date                            Principal Amount to be Paid

            SECTION 2.02.   Issuance and Terms of Equipment Notes.

            The Equipment Notes shall be dated the date of issuance
  thereof, shall be issued in two separate series consisting of Series G
  and Series C and in the maturities and principal amounts and shall bear
  interest as specified in Schedule I hereto.  On the date hereof, each
  Equipment Note shall be issued to the Pass Through Trustees (or their
  designee) under the Pass Through Agreements as set forth in Schedule II
  hereto in connection therewith. The Equipment Notes shall be issued in
  registered form only.  The Equipment Notes shall be issued in
  denominations of $1,000 and integral multiples thereof, except that one
  Equipment Note of each Series may be in an amount that is not an integral
  multiple of $1,000.

            Each Equipment Note shall bear interest at the Debt Rate
  (calculated on the basis of a year of 360 days comprised of twelve 30-day
  months) on the unpaid Principal Amount thereof from time to time
  outstanding, payable in arrears on _________ 20, ____, and on each
  February 20 and August 20 thereafter until maturity.  The Principal
  Amount of each Equipment Note shall be payable on the dates and in the
  installments equal to amount as set forth in Schedule I which shall be
  attached to the Equipment Notes.  Notwithstanding the foregoing, the
  final payment made under each Equipment Note shall be in an amount
  sufficient to discharge in full the unpaid Principal Amount and all
  accrued and unpaid interest on, and any other amounts due under, such
  Equipment Note.  Each Equipment Note shall bear interest at the Past Due
  Rate (calculated on the basis of a year of 360 days comprised of twelve
  30-day months) on any part of the Principal Amount, Make-Whole Amount, if
  any, and to the extent permitted by applicable law, interest and any
  other amounts payable thereunder not paid when due for any period during
  which the same shall be overdue, in each case for the period the same is
  overdue.  Amounts shall be overdue if not paid when due (whether at
  stated maturity, by acceleration or otherwise).  Notwithstanding anything
  to the contrary contained herein, if any date on which a payment under
  any Equipment Note becomes due and payable is not a Business Day then
  such payment shall not be made on such scheduled date but shall be made
  on the next succeeding Business Day with the same force and effect as if
  made on such scheduled date and if such payment is made on such next
  succeeding Business Day, no interest shall accrue on the amount of such
  payment from and after such scheduled date.

            The Owner Trustee agrees to pay to the Indenture Trustee for
  distribution in accordance with Section 3.04 hereof (i) to the extent not
  payable (whether or not in fact paid) under Section 7(a) of the Note
  Purchase Agreement (as originally in effect or amended with the consent
  of the Owner Participant), an amount or amounts equal to the fees payable
  to (x) the Liquidity Provider under Section 2.03 of each Liquidity
  Facility and the related Fee Letter (as defined in the Intercreditor
  Agreement) multiplied by a fraction the numerator of which shall be the
  then outstanding aggregate principal amount of the Series G Equipment
  Notes and Series C Equipment Notes and the denominator of which shall be
  the then outstanding aggregate  principal amount of all "Series G
  Equipment Notes" and "Series C Equipment Notes" (in each case as defined
  in the relevant Operative Indenture) issued under the Operative
  Indentures and (y) the Policy Provider under the Policy Fee Letter (as
  defined in the Policy Provider Agreement) multiplied by a fraction the
  numerator of which shall be the sum of the then outstanding aggregate
  principal amount of the Series G Equipment Notes and the denominator of
  which shall be the sum of the then outstanding aggregate principal amount
  of all "Series G Equipment Notes" (in each case as defined in the
  relevant Operative Indenture) issued under the Operative Indentures; (ii)
  (x) the amount equal to interest on any Downgrade Advance (other than any
  Applied  Downgrade Advance) payable under Section 3.07 of each Liquidity
  Facility minus Investment Earnings from such Downgrade Advance multiplied
  by (y) the fraction specified in the foregoing clause (i); (iii) (x) the
  amount equal to interest on any Non-Extension Advance (other than any
  Applied Non-Extension Advance) payable under Section 3.07 of each
  Liquidity Facility minus Investment Earnings from such Non-Extension
  Advance multiplied by (y) the fraction specified in the foregoing clause
  (i); (iv) if any payment default shall have occurred and be continuing
  with respect to interest on any Series G Equipment Note or Series C
  Equipment Note, (x) the excess, if any, of (1) an amount equal to
  interest on any Unpaid Advance,  Applied Downgrade Advance or Applied
  Non-Extension Advance payable under  Section 3.07 of each Liquidity
  Facility (or, in the case of the Series G Equipment Notes, if the Policy
  Provider has made a payment equivalent to such an Advance, as would have
  been payable under Section 3.07 of the applicable Liquidity Facility in
  respect of the Class G Pass Through Certificates had such Advance been
  made) over (2) the sum of Investment Earnings from any Final Advance plus
  any amount of interest at the Past Due Rate actually payable (whether or
  not in fact paid) by the Owner Trustee in respect of the overdue
  scheduled interest on the Equipment Notes in respect of which such Unpaid
  Advance, Applied Downgrade Advance or Applied Non-Extension Advance was
  made by the applicable Liquidity Provider (or, in the case of the Series
  G Equipment Notes, an equivalent payment was made by the Policy Provider)
  multiplied by (y) a fraction the  numerator of which shall be the then
  aggregate overdue amounts of interest on the Series G Equipment Notes and
  Series C Equipment Notes (other than interest becoming due and payable
  solely as a result of acceleration of any such Equipment Notes) and the
  denominator of which shall be the then aggregate overdue amounts of
  interest on all "Series G Equipment Notes" and "Series C Equipment Notes"
  (in each case as defined in the relevant Operative Indenture) issued
  under the Operative Indentures (other than interest becoming due and
  payable solely as a result of acceleration of any such "Equipment Notes,"
  (in each case as defined in the relevant Operative Indenture) issued
  under the Operative Indentures); (v) any other amounts owed to the
  Liquidity Provider by the Subordination Agent as borrower under each
  Liquidity  Facility  (other  than  amounts due as repayment of advances
  thereunder or as interest on such advances), except to the extent payable
  pursuant to clause (i), (ii),  (iii) or (iv) above multiplied by the
  fraction specified in the foregoing clause (i); and  (vi) all amounts for
  which the Policy Provider is entitled to reimbursement under Section
  3.7(i) of the Intercreditor Agreement multiplied by the fraction
  specified in the foregoing clause (i).  For purposes of this paragraph,
  the terms "Applied Downgrade Advance", "Applied Non-Extension Advance",
  "Cash Collateral Account", "Downgrade Advance", "Final Advance",
  "Investment Earnings", "Non-Extension Advance" and "Unpaid Advance" shall
  have the meanings specified in each Liquidity Facility or the
  Intercreditor Agreement.

            The Equipment Notes shall be executed on behalf of the Owner
  Trustee by its President or one of its Vice Presidents, Assistant Vice
  Presidents or Assistant Secretaries or other authorized officer.
  Equipment Notes bearing the signatures of individuals who were at any
  time the proper officers of the Owner Trustee shall bind the Owner
  Trustee, notwithstanding that such individuals or any of them have ceased
  to hold such offices prior to the authentication and delivery of such
  Equipment Notes or did not hold such offices at the respective dates of
  such Equipment Notes. The Owner Trustee may from time to time execute and
  deliver Equipment Notes with respect to the Aircraft to the Indenture
  Trustee for authentication upon original issue and such Equipment Notes
  shall thereupon be authenticated and delivered by the Indenture Trustee
  upon the written request of the Owner Trustee signed by a Vice President
  or Assistant Vice President or other authorized officer of the Owner
  Trustee; provided, however, that each such request shall specify the
  aggregate Principal Amount of all Equipment Notes to be authenticated
  hereunder on original issue with respect to the Aircraft. No Equipment
  Note shall be secured by or entitled to any benefit under this Trust
  Indenture or be valid or obligatory for any purposes, unless there
  appears on such Equipment Note a certificate of authentication in the
  form provided for herein executed by the Indenture Trustee by the manual
  signature of one of its authorized officers and such certificate upon any
  Equipment Notes shall be conclusive evidence, and the only evidence, that
  such Equipment Note has been duly authenticated and delivered hereunder.

            SECTION 2.03.   Payments from Trust Indenture Estate Only.

            (a)  Without impairing any of the other rights, powers,
  remedies, privileges, liens or security interests of the Note Holders
  under this Trust Indenture, each Note Holder, by its acceptance of an
  Equipment Note, agrees that as between it and the Owner Trustee, except
  as expressly provided in this Trust Indenture, the Participation
  Agreement or any other Operative Document, (i) the obligation to make all
  payments of the Principal Amount of, interest on, Make-Whole Amount, if
  any, and all other amounts due with respect to the Equipment Notes, and
  the performance by the Owner Trustee of every obligation or covenant
  contained in this Trust Indenture and in the Participation Agreement or
  any of the other Operative Documents, shall be payable only from the
  income and proceeds from the Trust Estate to the extent included in the
  Trust Indenture Estate and only to the extent that the Owner Trustee
  shall have sufficient income or proceeds from the Trust Estate to the
  extent included in the Trust Indenture Estate to enable the Indenture
  Trustee to make such payments in accordance with the terms of Article III
  hereof, and all of the statements, representations, covenants and
  agreements made by the Owner Trustee (when made in such capacity)
  contained in this Trust Indenture and any agreement referred to herein
  other than the Trust Agreement, unless expressly otherwise stated, are
  made and intended only for the purpose of binding the Trust Estate and
  establishing the existence of rights and remedies which can be exercised
  and enforced against the Trust Estate; therefore, anything contained in
  this Trust Indenture or such other agreements to the contrary
  notwithstanding (except for any express provisions or representations
  that the Owner Trustee is responsible for, or is making, in its
  individual capacity, for which there would be personal liability of the
  Owner Trustee), no recourse shall be had with respect to this Trust
  Indenture or such other agreements against the Owner Trustee in its
  individual capacity or against any institution or Person which becomes a
  successor trustee or co-trustee or any officer, director, trustee,
  servant or direct or indirect parent or controlling Person or Persons of
  any of them, and (ii) none of the Owner Trustee, in its individual
  capacity, the Owner Participant, the Indenture Trustee and any officer,
  director, trustee, servant, employee, agent or direct or indirect parent
  or controlling Person or Persons of any of them shall have any personal
  liability for any amounts payable, or other obligation owed, hereunder,
  under the Participation Agreement or any of the other Operative Documents
  or under the Equipment Notes except as expressly provided herein or in
  the Participation Agreement; provided, however, that nothing contained in
  this Section 2.03(a) shall be construed to limit the exercise and
  enforcement in accordance with the terms of this Trust Indenture or such
  other agreements of rights and remedies against the Trust Estate.

            (b)  If (i) all or any part of the Trust Estate becomes the
  property of, or the Owner Trustee or Owner Participant becomes, a debtor
  subject to the reorganization provisions of the Bankruptcy Code, (ii)
  pursuant to such reorganization provisions, including Section 1111(b) of
  the Bankruptcy Code, the Owner Trustee (in its individual capacity) or
  the Owner Participant is required, by reason of the Owner Trustee (in its
  individual capacity) or the Owner Participant being held to have recourse
  liability to any Note Holder or the Indenture Trustee, directly or
  indirectly (other than the recourse liability of the Owner Trustee (in
  its individual capacity)), to make payment on account of any amount
  payable as principal, Make-Whole Amount, if any, interest or other
  amounts on the Equipment Notes or under this Indenture and (iii) any Note
  Holder or the Indenture Trustee actually receives any Indenture Excess
  Amount (as hereinafter defined) which reflects any payment by the Owner
  Trustee (in its individual capacity) or the Owner Participant on account
  of clause (ii) above, then such Note Holder or the Indenture Trustee, as
  the case may be, shall promptly refund to the Owner Trustee (in its
  individual capacity) or the Owner Participant (whichever shall have made
  such payment) such Indenture Excess Amount.

            For purposes of this Section 2.03(b), "Indenture Excess Amount"
  means the amount by which such payment exceeds the amount that would have
  been received by a Note Holder or the Indenture Trustee if the Owner
  Trustee (in its individual capacity) or the Owner Participant had not
  become subject to the recourse liability referred to in clause (ii)
  above.  Nothing contained in this Section 2.03(b) shall prevent a Note
  Holder or the Indenture Trustee from enforcing any personal recourse
  obligation (and retaining the proceeds thereof) of the Owner Trustee (in
  its individual capacity) or the Owner Participant under the Participation
  Agreement or this Trust Indenture (and any exhibits or annexes hereto or
  thereto) or by separate agreement or from retaining any amount paid by
  Owner Participant under Section 2.14 or 4.03 hereof.

            SECTION 2.04.   Method of Payment.

            (a)  The Principal Amount of, interest on, Make-Whole Amount,
  if any, and other amounts due under each Equipment Note or hereunder will
  be payable in Dollars by wire transfer of immediately available funds not
  later than 11:00 a.m., New York City time, on the due date of payment to
  the Indenture Trustee at the Corporate Trust Office for distribution
  among the Note Holders in the manner provided herein.  The Owner Trustee
  shall not have any responsibility for the distribution of such payment to
  any Note Holder. Notwithstanding the foregoing or any provision in any
  Equipment Note to the contrary, the Indenture Trustee will use reasonable
  efforts to pay or cause to be paid, if so directed in writing by any Note
  Holder (with a copy to the Owner Trustee), all amounts paid by the Owner
  Trustee hereunder and under such holder's Equipment Note or Equipment
  Notes to such holder or a nominee therefor (including all amounts
  distributed pursuant to Article III of this Trust Indenture) by
  transferring, or causing to be transferred, by wire transfer of
  immediately available funds in Dollars, prior to 2:00 p.m., New York City
  time, on the due date of payment, to an account maintained by such holder
  with a bank located in the continental United States the amount to be
  distributed to such holder, for credit to the account of such holder
  maintained at such bank. If the Indenture Trustee shall fail to make any
  such payment as provided in the immediately preceding sentence after its
  receipt of funds at the place and prior to the time specified above, the
  Indenture Trustee, in its individual capacity and not as trustee, agrees
  to compensate such holders for loss of use of funds at the Federal Funds
  Rate until such payment is made and the Indenture Trustee shall be
  entitled to any interest earned on such funds until such payment is made.
  Any payment made hereunder shall be made without any presentment or
  surrender of any Equipment Note, except that, in the case of the final
  payment in respect of any Equipment Note, such Equipment Note shall be
  surrendered to the Indenture Trustee for cancellation promptly after such
  payment.  Notwithstanding any other provision of this Trust Indenture to
  the contrary, the Indenture Trustee shall not be required to make, or
  cause to be made, wire transfers as aforesaid prior to the first Business
  Day on which it is practicable for the Indenture Trustee to do so in view
  of the time of day when the funds to be so transferred were received by
  it if such funds were received after 11:00 a.m., New York City time, at
  the place of payment.  Prior to the due presentment for registration of
  transfer of any Equipment Note, the Owner Trustee and the Indenture
  Trustee shall deem and treat the Person in whose name any Equipment Note
  is registered on the Equipment Note Register as the absolute owner and
  holder of such Equipment Note for the purpose of receiving payment of all
  amounts payable with respect to such Equipment Note and for all other
  purposes, and neither the Owner Trustee nor the Indenture Trustee shall
  be affected by any notice to the contrary.  So long as any signatory to
  the Participation Agreement or nominee thereof shall be a registered Note
  Holder, all payments to it shall be made to the account of such Note
  Holder specified in Schedule I thereto and otherwise in the manner
  provided in or pursuant to the Participation Agreement unless it shall
  have specified some other account or manner of payment by notice to the
  Indenture Trustee consistent with this Section 2.04.

            (b)  The Indenture Trustee, as agent for the Owner Trustee,
  shall exclude and withhold at the appropriate rate from each payment of
  Principal Amount of, interest on, Make-Whole Amount, if any, and other
  amounts due hereunder or under each Equipment Note (and such exclusion
  and withholding shall constitute payment in respect of such Equipment
  Note) any and all United States withholding taxes applicable thereto as
  required by Law.  The Indenture Trustee agrees to act as such withholding
  agent and, in connection therewith, whenever any present or future United
  States taxes or similar charges are required to be withheld with respect
  to any amounts payable hereunder or in respect of the Equipment Notes, to
  withhold such amounts (and such withholding shall constitute payment in
  respect of such Equipment Note) and timely pay the same to the
  appropriate authority in the name of and on behalf of the Note Holders,
  that it will file any necessary United States withholding tax returns or
  statements when due, and that as promptly as possible after the payment
  thereof it will deliver to each Note Holder (with a copy to the Owner
  Trustee and Lessee) appropriate receipts showing the payment thereof,
  together with such additional documentary evidence as any such Note
  Holder may reasonably request from time to time.

            If a Note Holder which is a Non-U.S. Person has furnished to
  the Indenture Trustee a properly completed and currently effective U.S.
  Internal Revenue Service Form 1001, W-8 or W-8BEN (or such successor form
  or forms as may be required by the United States Treasury Department)
  during the calendar year in which the payment hereunder or under the
  Equipment Note(s) held by such holder is made (but prior to the making of
  such payment), or in either of the two preceding calendar years, and has
  not notified the Indenture Trustee of the withdrawal or inaccuracy of
  such form prior to the date of such payment (and the Indenture Trustee
  has no reason to know that any information set forth in such form is
  inaccurate), the Indenture Trustee shall withhold only the amount, if
  any, required by Law (after taking into account any applicable exemptions
  claimed by the Note Holder) to be withheld from payments hereunder or
  under the Equipment Notes held by such holder in respect of United States
  federal income tax (and such withholding shall constitute payment in
  respect of such Equipment Note).  If a Note Holder (x) which is a Non-
  U.S. Person has furnished to the Indenture Trustee a properly completed
  and currently effective U.S. Internal Revenue Service Form 4224 or W-8ECI
  in duplicate (or such successor certificate, form or forms as may be
  required by the United States Treasury Department as necessary in order
  to avoid withholding of United States federal income tax), during the
  calendar year in which the payment is made (but prior to the making of
  such payment), and has not notified the Indenture Trustee of the
  withdrawal or inaccuracy of such certificate or form prior to the date of
  such payment (and the Indenture Trustee has no reason to know that any
  information set forth in such form is inaccurate) or (y) which is a U.S.
  Person has furnished to the Indenture Trustee a properly completed and
  currently effective U.S. Internal Revenue Service Form W-9 (or such
  successor form or forms as may be required by the United States Treasury
  Department), if applicable, prior to a payment hereunder or under the
  Equipment Notes held by such holder, no amount shall be withheld from
  payments in respect of United States federal income tax.  If any Note
  Holder has notified the Indenture Trustee that any of the foregoing forms
  or certificates is withdrawn or inaccurate, or if such holder has not
  filed a form claiming an exemption from United States withholding tax or
  if the Code or the regulations thereunder or the administrative
  interpretation thereof are at any time after the date hereof amended to
  require such withholding of United States federal income taxes from
  payments under the Equipment Notes held by such holder, the Indenture
  Trustee agrees to withhold from each payment due to the relevant Note
  Holder withholding taxes at the appropriate rate under Law and will, on a
  timely basis as more fully provided above, deposit such amounts with an
  authorized depository and make such returns, statements, receipts and
  other documentary evidence in connection therewith as required by
  applicable law.  Neither the Owner Participant nor the Owner Trustee
  shall be liable if the Indenture Trustee fails to withhold withholding
  taxes in accordance with this Section 2.04 or if any Note Holder provides
  false or inaccurate information on any form required to be delivered
  under this Section 2.04.

            SECTION 2.05.   Application of Payments.

            In the case of each Equipment Note, each payment of Principal
  Amount, Make-Whole Amount, if any, and interest or other amounts due
  thereon shall be applied:

            First:  to the payment of accrued interest on such Equipment
  Note (as well as any interest on any overdue Principal Amount, any
  overdue Make-Whole Amount, if any, and to the extent permitted by Law,
  any overdue interest and any other overdue amounts thereunder) to the
  date of  such payment;

            Second:  to the payment of the Principal Amount of such
  Equipment Note (or a portion thereof) then due thereunder (other than by
  reason of redemption);

            Third:  to the payment of Make-Whole Amount, if any, and any
  other amount due hereunder or under such Equipment Note; and

            Fourth:  the balance, if any, remaining thereafter, to the
  payment of the Principal Amount of such Equipment Note remaining unpaid
  and due by reason of redemption (provided that such Equipment Note shall
  not be subject to redemption except as provided in Sections 2.10, 2.11
  and 2.12 hereof).

            The amounts paid pursuant to clause "Fourth" above shall be
  applied to the installments of Principal Amount of such Equipment Note in
  the inverse order of their normal maturity.  Notwithstanding the
  foregoing, each indemnity payment or payment of transaction costs or
  expenses received hereunder or under another Operative Document shall be
  applied for the purpose (directly or by reimbursement) for which such
  amount was paid.

            SECTION 2.06.   Termination of Interest in Trust Indenture
  Estate.

            A Note Holder and Indenture Indemnitees shall not, as such,
  have any further interest in, or other right with respect to, the Trust
  Indenture Estate when and if the Secured Obligations due to such Note
  Holder or Indenture Indemnitee shall have been paid in full.

            SECTION 2.07.   Registration, Transfer and Exchange of
  Equipment Notes.

            The Indenture Trustee shall keep a register (the "Equipment
  Note Register") in which the Indenture Trustee shall provide for the
  registration of Equipment Notes and the registration of transfers of
  Equipment Notes. No such transfer shall be given effect unless and until
  registration hereunder shall have occurred.  The Equipment Note Register
  shall be kept at the Corporate Trust Office of the Indenture Trustee.
  The Indenture Trustee is hereby appointed "Equipment Note Registrar" for
  the purpose of registering Equipment Notes and transfers of Equipment
  Notes as herein provided. A holder of any Equipment Note intending to
  exchange such Equipment Note shall surrender such Equipment Note to the
  Indenture Trustee at the Corporate Trust Office, together with a written
  request from the registered holder thereof for the issuance of a new
  Equipment Note, specifying, in the case of a surrender for transfer, the
  name and address of the new holder or holders.  Upon surrender for
  registration of transfer of any Equipment Note, the Owner Trustee shall
  execute, and the Indenture Trustee shall authenticate and deliver, in the
  name of the designated transferee or transferees, one or more new
  Equipment Notes of a like aggregate Principal Amount and of the same
  series.  At the option of the Note Holder, Equipment Notes may be
  exchanged for other Equipment Notes of any authorized denominations of a
  like aggregate Principal Amount, upon surrender of the Equipment Notes to
  be exchanged to the Indenture Trustee at the Corporate Trust Office.
  Whenever any Equipment Notes are so surrendered for exchange, the Owner
  Trustee shall execute, and the Indenture Trustee shall authenticate and
  deliver, the Equipment Notes which the Note Holder making the exchange is
  entitled to receive.  All Equipment Notes issued upon any registration of
  transfer or exchange of Equipment Notes (whether under this Section 2.07
  or under Section 2.08 hereof or otherwise under this Trust Indenture)
  shall be the valid obligations of the Owner Trustee evidencing the same
  respective obligations, and entitled to the same security and benefits
  under this Trust Indenture, as the Equipment Notes surrendered upon such
  registration of transfer or exchange.  Every Equipment Note presented or
  surrendered for registration of transfer, shall (if so required by the
  Indenture Trustee) be duly endorsed, or be accompanied by a written
  instrument of transfer in form satisfactory to the Indenture Trustee duly
  executed by the Note Holder or such holder's attorney duly authorized in
  writing, and the Indenture Trustee shall require evidence satisfactory to
  it as to the compliance of any such transfer with the Securities Act, and
  the securities Laws of any applicable state.  The Indenture Trustee shall
  make a notation on each new Equipment Note of the amount of all payments
  of Principal Amount previously made on the old Equipment Note or
  Equipment Notes with respect to which such new Equipment Note is issued
  and the date to which interest on such old Equipment Note or Equipment
  Notes has been paid.  Interest shall be deemed to have been paid on such
  new Equipment Note to the date on which interest shall have been paid on
  such old Equipment Note, and all payments of the Principal Amount marked
  on such new Equipment Note, as provided above, shall be deemed to have
  been made thereon.  The Owner Trustee shall not be required to exchange
  any surrendered Equipment Notes as provided above during the ten-day
  period preceding the due date of any payment on such Equipment Note.  The
  Owner Trustee shall in all cases deem the Person in whose name any
  Equipment Note shall have been issued and registered as the absolute
  owner and holder of such Equipment Note for the purpose of receiving
  payment of all amounts payable by the Owner Trustee with respect to such
  Equipment Note and for all purposes until a notice stating otherwise is
  received from the Indenture Trustee and such change is reflected on the
  Equipment Note Register.  The Indenture Trustee will promptly notify the
  Owner Trustee, the Owner Participant and Lessee of each registration of a
  transfer of an Equipment Note.  Any such transferee of an Equipment Note,
  by its acceptance of an Equipment Note, agrees to the provisions of the
  Participation Agreement applicable to Note Holders, including Sections 5,
  7(a), 7(c), 7(g), 7(h), 7(n), 7(q), 7(u) and 7(z), 9, 12(a), 12(b), 14(b)
  and 14(e), and shall be deemed to have represented and warranted (except
  as provided above), and covenanted, to the parties to the Participation
  Agreement as to the matters represented, warranted and covenanted by the
  Purchasers in the Participation Agreement.  Subject to compliance by the
  Note Holder and its transferee (if any) of the requirements set forth in
  this Section 2.07, the Indenture Trustee and the Owner Trustee shall use
  all reasonable efforts to issue new Equipment Notes upon transfer or
  exchange within ten (10) Business Days of the date an Equipment Note is
  surrendered for transfer or exchange.

            SECTION 2.08.   Mutilated, Destroyed, Lost or Stolen Equipment
  Notes.

            If any Equipment Note shall become mutilated, destroyed, lost
  or stolen, the Owner Trustee shall, upon the written request of the
  holder of such Equipment Note, execute and the Indenture Trustee shall
  authenticate and deliver in replacement thereof a new Equipment Note,
  payable in the same Principal Amount dated the same date and captioned as
  issued in connection with the Aircraft.  If the Equipment Note being
  replaced has become mutilated, such Equipment Note shall be surrendered
  to the Indenture Trustee and a photocopy thereof shall be furnished to
  the Owner Trustee.  If the Equipment Note being replaced has been
  destroyed, lost or stolen, the holder of such Equipment Note shall
  furnish to the Owner Trustee, the Owner Participant and the Indenture
  Trustee such security or indemnity as may be required by them to save the
  Owner Trustee, the Owner Participant and the Indenture Trustee harmless
  and evidence satisfactory to the Owner Trustee, the Owner Participant and
  the Indenture Trustee of the destruction, loss or theft of such Equipment
  Note and of the ownership thereof.  If a "qualified institutional buyer"
  of the type referred to in paragraph (a)(l)(i)(A), (B), (D) or (E) of
  Rule 144A under the Securities Act (a "QIB") is the holder of any such
  destroyed, lost or stolen Equipment Note, then the written indemnity of
  such QIB, signed by an authorized officer thereof, in favor of, delivered
  to and in form reasonably satisfactory to Lessee, the Owner Participant,
  the Owner Trustee and the Indenture Trustee shall be accepted as
  satisfactory indemnity and security and no further indemnity or security
  shall be required as a condition to the execution and delivery of such
  new Equipment Note. Subject to compliance by the Note Holder of the
  requirements set forth in this Section 2.08, the Indenture Trustee and
  the Owner Trustee shall use all reasonable efforts to issue new Equipment
  Notes within ten (10) Business Days of the date of the written request
  therefor from the Note Holder.

            SECTION 2.09.   Payment of Expenses on Transfer; Cancellation.

            (a)  No service charge shall be made to a Note Holder for any
  registration of transfer or exchange of Equipment Notes, but the
  Indenture Trustee, as Equipment Note Registrar, may require payment from
  the party requesting such new Equipment Note of a sum sufficient to cover
  any tax or other governmental charge that may be imposed in connection
  with any registration of transfer or exchange of Equipment Notes.

            (b)  The Indenture Trustee shall cancel all Equipment Notes
  surrendered for replacement, redemption, transfer, exchange, payment or
  cancellation and shall destroy the canceled Equipment Notes.

            SECTION 2.10.   Mandatory Redemptions of Equipment Notes.

            (a)  On the date on which Lessee is required pursuant to
  Section 10(a)(i) of the Lease to make payment for an Event of Loss with
  respect to the Aircraft, all of the Equipment Notes shall be redeemed in
  whole at a redemption price equal to 100% of the unpaid Principal Amount
  thereof, together with all accrued interest thereon to the date of
  redemption and all other amounts payable hereunder or under the
  Participation Agreement to the Note Holders but without the Make-Whole
  Amount.

            (b)  If the Lease is terminated with respect to the Aircraft by
  Lessee pursuant to Section 9, Section 19(b) or Section 20 thereof and
  Lessee shall not have assumed all of the obligations of the Owner Trustee
  hereunder pursuant to Section 2.13 and Section 7(u) of the Participation
  Agreement, on the date the Lease is so terminated all the Equipment Notes
  shall be redeemed in whole at a redemption price equal to 100% of the
  unpaid Principal Amount thereof, together with accrued interest thereon
  to the date of redemption and all other amounts payable hereunder or
  under the Participation Agreement to the Note Holders plus the Make-Whole
  Amount, if any.

            SECTION 2.11.   Voluntary Redemptions of Equipment Notes.

            All, but not less than, all of the Equipment Notes may be
  redeemed by the Owner Trustee with the prior consent of Lessee upon at
  least 20 days revocable prior written notice to the Indenture Trustee, at
  a redemption price equal to 100% of the unpaid Principal Amount thereof,
  together with accrued interest thereon to the date of redemption and all
  other amounts payable hereunder or under the Participation Agreement to
  the Note Holders plus the Make-Whole Amount, if any.

            SECTION 2.12.   Redemptions; Notice of Redemption.

            (a)  Neither any redemption of any Equipment Note nor any
  purchase by the Owner Trustee of any Equipment Note may be made except to
  the extent and in the manner expressly permitted by this Trust Indenture.
  No purchase of any Equipment Note may be made by the Indenture Trustee.

            (b)  Notice of redemption or purchase with respect to the
  Equipment Notes shall be given by the Indenture Trustee by first-class
  mail, postage prepaid, mailed not less than 15 nor more than 60 days
  prior to the applicable redemption date, to each Note Holder of such
  Equipment Notes to be redeemed or purchased, at such Note Holder's
  address appearing in the Equipment Note Register; provided, that in the
  case of a redemption to be made pursuant to Section 2.10(b) or Section
  2.11, such notice shall be revocable and shall be deemed revoked in the
  event that the Lease does not in fact terminate on the specified
  termination date or if notice of such redemption shall have been given in
  connection with a refinancing of Equipment Notes and the Indenture
  Trustee receives written notice of such revocation from Lessee or the
  Owner Trustee not later than three days prior to the redemption date.
  All notices of redemption shall state: (1) the redemption date, (2) the
  applicable basis for determining the redemption price, (3) that on the
  redemption date, the redemption price will become due and payable upon
  each such Equipment Note, and that, if any such Equipment Notes are then
  outstanding, interest on such Equipment Notes shall cease to accrue on
  and after such redemption date, and (4) the place or places where such
  Equipment Notes are to be surrendered for payment of the redemption
  price.

            (c)  On or before the redemption date, the Owner Trustee (or
  any Person on behalf of the Owner Trustee) shall, to the extent an amount
  equal to the redemption price for the Equipment Notes to be redeemed or
  purchased on the redemption date shall not then be held in the Trust
  Indenture Estate, deposit or cause to be deposited with the Indenture
  Trustee by 11:00 a.m. New York City time on the redemption date in
  immediately available funds the redemption price of the Equipment Notes
  to be redeemed or purchased.

            (d)  Notice of redemption or purchase having been given as
  aforesaid (and not deemed revoked as contemplated in the proviso to
  Section 2.12(b)), the Equipment Notes to be redeemed or purchased shall,
  on the redemption date, become due and payable at the Corporate Trust
  Office of the Indenture Trustee or at any office or agency maintained for
  such purposes pursuant to Section 2.07, and from and after such
  redemption date (unless there shall be a default in the payment of the
  redemption price) any such Equipment Notes then outstanding shall cease
  to bear interest.  Upon surrender of any such Equipment Note for
  redemption or purchase in accordance with said notice, such Equipment
  Note shall be redeemed at the redemption price.  If any Equipment Note
  called for redemption or purchase shall not be so paid upon surrender
  thereof for redemption, the principal amount thereof shall, until paid,
  continue to bear interest from the applicable redemption date at the
  interest rate in effect for such Equipment Note as of such redemption
  date.

            SECTION 2.13.   Assumption of Equipment Notes by Lessee.

            If, in accordance with Section 7(u) of the Participation
  Agreement Lessee shall assume (on a full recourse basis) all of the
  obligations of the Owner Trustee hereunder, under the Equipment Notes and
  all other Operative Documents by supplemental indenture satisfactory to
  the Indenture Trustee (which shall contain (i) the provisions
  substantially similar to Sections 6, 7, 8, 10, 11 and 12 of the Lease and
  (ii) other provisions necessary or advisable to effectuate such
  assumption), then upon delivery of such supplemental indenture, payment
  by Lessee of all expenses (including reasonable fees and expenses of
  counsel) for the Owner Trustee and the Owner Participant and delivery of
  an opinion of counsel for Lessee that such assumption has been duly and
  validly effected, the Owner Trustee shall be released and discharged from
  any further obligations hereunder and under the Equipment Notes and all
  other Operative Documents and the Owner Participant shall be released and
  discharged from any further obligations under the Participation Agreement
  and any other Operative Document to which it is a party, except with
  respect to any such obligations that accrued prior thereto.

            SECTION 2.14.   Option to Purchase Equipment Notes.

            Either the Owner Trustee or the Owner Participant may, upon the
  events and subject to the terms and conditions and for the price set
  forth in this Section 2.14, purchase all but not less than all of the
  Equipment Notes outstanding hereunder, and each Note Holder agrees that
  it will, upon such events and subject to such terms and conditions and
  upon receipt of such price, sell, assign, transfer and convey to such
  purchaser or its nominee (without recourse or warranty of any kind except
  as to its title to the Equipment Notes and except against Liens on such
  Equipment Notes arising by, through or under such holder), all of the
  right, title and interest of such Note Holder in and to the Trust
  Indenture Estate, this Trust Indenture and the Equipment Notes held by
  it, and such purchaser or its nominee shall assume all of such holder's
  obligations under the Participation Agreement and hereunder.

            Such option to purchase the Equipment Notes may be exercised by
  the Owner Trustee or the Owner Participant at any time following the
  occurrence of any of the following events, and, in any such event, the
  purchase price thereof shall equal for each Equipment Note the aggregate
  unpaid Principal Amount thereof, plus accrued and unpaid interest thereon
  to, but not including, the date of purchase and all other amounts (other
  than the Make-Whole Amount, except as provided in the next sentence) then
  payable hereunder or under the Participation Agreement to the holder
  thereof. Such option to purchase the Equipment Notes may be exercised:
  (i) upon an Indenture Trustee Event or (ii) in the event there shall have
  occurred and be continuing a Lease Event of Default, provided, that if
  such option is exercised pursuant to this clause (ii) at a time when
  there shall have occurred and be continuing for less than one hundred
  eighty (180) days a Lease Event of Default, the purchase price thereof
  shall equal the price provided in the preceding sentence plus the Make-
  Whole Amount, if any.

            Such option to purchase the Equipment Notes may be exercised by
  the Owner Trustee or the Owner Participant giving written notice of its
  election of such option to the Indenture Trustee, which notice (i) shall
  specify a date for such purchase not more than thirty (30) days or less
  than fifteen (15) days after the date of such notice and (ii) may specify
  that its election of such option is contingent upon the trustee or the
  debtor-in-possession in a proceeding involving Lessee under Chapter 11 of
  the Bankruptcy Code not entering into an agreement during the Section
  1110 Period to perform the Lease.  The Indenture Trustee shall not
  exercise any of the remedies hereunder or, without the consent of the
  Owner Trustee or the Owner Participant, under the Lease, during the
  period from the time that a notice of exercise by the Owner Participant
  of such option to purchase becomes irrevocable until the date on which
  such purchase is required to occur pursuant to the terms of the preceding
  sentence.  Such election to purchase the Equipment Notes shall become
  irrevocable (subject to the provision in clause (ii) of the first
  sentence of this paragraph) upon the fifteenth day preceding the date
  specified in the written notice described in the first sentence of this
  paragraph.

            If the Owner Trustee or the Owner Participant on or before the
  date of such purchase shall so request, the Note Holders will comply with
  all the provisions of Section 2.07 to enable new Equipment Notes to be
  issued to the Owner Trustee or the Owner Participant or its nominee in
  such denominations as the Owner Trustee or the Owner Participant shall
  request.  All taxes, charges and expenses required pursuant to Section
  2.09 in connection with the issuance of such new Equipment Note shall be
  borne by the Owner Participant.

            SECTION 2.15.   Subordination.

            (a)  The Owner Trustee and, by acceptance of its Equipment
  Notes of any Series, each Note Holder of such Series, hereby agree that
  no payment or distribution shall be made on or in respect of the Secured
  Obligations owed to such Note Holder of such Series, including any
  payment or distribution of cash, property or securities after the
  commencement of a proceeding of the type referred to in Section 4.02(g)
  hereof, except as expressly provided in Article III hereof.

            (b)  By the acceptance of its Equipment Notes of any Series
  (other than Series G), each Note Holder of such Series agrees that in the
  event that such Note Holder, in its capacity as a Note Holder, shall
  receive any payment or distribution on any Secured Obligations in respect
  of such Series which it is not entitled to receive under this Section
  2.15 or Article III hereof, it will hold any amount so received in trust
  for the Senior Holder (as defined in Section 2.15(c) hereof) and will
  forthwith turn over such payment to the Indenture Trustee in the form
  received to be applied as provided in Article III hereof.

            (c)  As used in this Section 2.15, the term "Senior Holder"
  shall mean, (i) the Note Holders of Series G until the Secured
  Obligations in respect of Series G have been paid in full and (ii) after
  the Secured Obligations in respect of Series G Equipment Notes have been
  paid in full, the Note Holders of Series C until the Secured Obligations
  in respect of Series C Equipment Notes have been paid in full.

                                ARTICLE III

                  RECEIPT, DISTRIBUTION AND APPLICATION OF
                   INCOME FROM THE TRUST INDENTURE ESTATE

            SECTION 3.01.   Basic Rent Distribution.

            Except as otherwise provided in Sections 3.02 and 3.03 hereof,
  each installment of Basic Rent, any payment of interest on overdue
  installments of Basic Rent [,any payment received from the Owner
  Participant pursuant to Section 7(cc) of the Participation Agreement](3)
  and any payment received by the Indenture Trustee pursuant to Section
  4.03 hereof shall be promptly distributed in the following order of
  priority:

  ------------------

  3      For deferred equity transactions only.


            First, (i) so much of such installment or payment as shall be
  required to pay in full the aggregate amount of the payment or payments
  of Principal Amount and interest and other amounts (as well as any
  interest on any overdue Principal Amount and, to the extent permitted by
  applicable law, on any overdue interest and any other overdue amounts)
  then due under all Series G Equipment Notes shall be distributed to the
  Note Holders of Series G ratably, without priority of one over the other,
  in the proportion that the amount of such payment or payments then due
  under each Series G Equipment Note bears to the aggregate amount of the
  payments then due under all Series G Equipment Notes; and (ii) after
  giving effect to paragraph (i) above, so much of such installment or
  payment remaining as shall be required to pay in full the aggregate
  amount of the payment or payments of Principal Amount and interest and
  other amounts (as well as any interest on any overdue Principal Amount
  and, to the extent permitted by applicable law, on any overdue interest
  and any other overdue amounts) then due under all Series C Equipment
  Notes shall be distributed to the Note Holders of Series C ratably,
  without priority of one over the other, in the proportion that the amount
  of such payment or payments then due under each Series C Equipment Note
  bears to the aggregate amount of the payments then due under all Series C
  Equipment Notes; and

            Second, the balance, if any, of such installment remaining
  thereafter  shall be distributed to the Owner Trustee free and clear of
  the Lien of this Indenture; provided, however, that if an Event of
  Default shall have occurred and be continuing, then such balance shall
  not be distributed as provided in this clause "Second" but shall be held
  by the Indenture Trustee as part of the Trust Indenture Estate and
  invested in accordance with Section 5.09 hereof until whichever of the
  following shall first occur: (i) all Events of Default shall have been
  cured or waived, in which event such balance shall be distributed as
  provided in this clause "Second" without reference to this proviso, (ii)
  Section 3.03 hereof shall be applicable, in which event such balance
  shall be distributed in accordance with the provisions of such Section
  3.03, or (iii) the 120th day after the receipt of such payment in which
  case such payment shall be distributed as provided in this clause
  "Second" without reference to this proviso.

            SECTION 3.02.   Event of Loss; Replacement; Voluntary
  Termination; Refinancing.

            Except as otherwise provided in Section 3.03 hereof, any
  payments received by the Indenture Trustee (i) with respect to the
  Aircraft as the result of an Event of Loss, (ii) pursuant to a voluntary
  termination of the Lease pursuant to Section 9, 19(b) or 20 thereof,
  (iii) in connection with a refinancing of the Equipment Notes pursuant to
  Section 16 of the Participation Agreement or (iv) in connection with any
  optional redemption of the Equipment Notes effected in accordance with
  the Operative Documents, shall be applied to redemption of the Equipment
  Notes, to payment of the Secured Obligations or to the Indenture Trustee
  or any Note Holder under the Participation Agreement by applying such
  funds in the following order of priority:

            First, (i) to reimburse the Indenture Trustee and the Note
  Holders for any reasonable costs or expenses incurred in connection with
  such redemption for which they are entitled to reimbursement, or
  indemnity by Lessee, under the Operative Documents and then (ii) to pay
  any other amounts then due to the Indenture Trustee and the Note Holders
  under this Trust Indenture, the Participation Agreement or the Equipment
  Notes (other than amounts specified in clause Second below);

            Second, (i) to pay the amounts specified in paragraph (i) of
  clause "Third" of Section 3.03 hereof plus Make-Whole Amount, if any,
  then due and payable in respect of the Series G Equipment Notes; and (ii)
  after giving effect to paragraph (i) above, to pay the amounts specified
  in paragraph (ii) of clause "Third" of Section 3.03 hereof plus Make-
  Whole Amount, if any, then due and payable in respect of the Series C
  Equipment Notes; and

            Third, as provided in clause "Fourth" of Section 3.03 hereof;
  provided, however, that if a Replacement Airframe or Replacement Engine
  shall be substituted for the Airframe or Engine subject to such Event of
  Loss as provided in Section 10 of the Lease and as permitted by  Section
  5.06 hereof, any insurance, condemnation or similar proceeds which result
  from such Event of Loss and are paid over to the Indenture Trustee shall
  be held by the Indenture Trustee as permitted by Section 6.04 hereof
  (provided that such moneys shall be invested as provided in Section 5.09
  hereof) as additional security for the obligations of Lessee under the
  Lessee Documents and, unless otherwise applied pursuant to the Lease,
  such proceeds (and such investment earnings) shall be released to Lessee
  at Lessee's written request upon the release of such damaged Airframe or
  Engine and the replacement thereof as provided in the Lease.

            SECTION 3.03.   Payments After Event of Default.

            Except as otherwise provided in Section 3.04 hereof, all
  payments received and amounts held or realized by the Indenture Trustee
  (including any amounts realized by the Indenture Trustee from the
  exercise of any remedies pursuant to Section 15 of the Lease or Article
  IV hereof) after both an Event of Default shall have occurred and be
  continuing and the Equipment Notes shall have become due and payable
  pursuant to Section 4.04(b) hereof, as well as all payments or amounts
  then held by the Indenture Trustee as part of the Trust Indenture Estate,
  shall be promptly distributed by the Indenture Trustee in the following
  order of priority:

            First, so much of such payments or amounts as shall be required
  to reimburse the Indenture Trustee for any tax, expense or other loss
  (including, without limitation, all amounts to be expended at the expense
  of, or charged upon the tolls, rents, revenues, issues, products and
  profits of, the property included in the Trust Indenture Estate (all such
  property being herein called the "Mortgaged Property") pursuant to
  Section 4.05(b) hereof) incurred by the Indenture Trustee (to the extent
  not previously reimbursed), the expenses of any sale, taking or other
  proceeding, reasonable attorneys' fees and expenses, court costs, and any
  other expenditures incurred or expenditures or advances made by the
  Indenture Trustee or the Note Holders in the protection, exercise or
  enforcement of any right, power or remedy or any damages sustained by the
  Indenture Trustee or any Note Holder, liquidated or otherwise, upon such
  Event of Default shall be applied by the Indenture Trustee as between
  itself and the Note Holders in reimbursement of such expenses and any
  other expenses for which the Indenture Trustee or the Note Holders are
  entitled to reimbursement under any Operative Document and all amounts
  payable to the other Indenture Indemnitees hereunder and under the
  Participation Agreement and the Lease excluding those amounts described
  in clauses Second and Third below, and in the case the aggregate amount
  to be so distributed is insufficient to pay as aforesaid, then ratably,
  without priority of one over the other, in proportion to the amounts owed
  each hereunder;

            Second, so much of such payments or amounts remaining as shall
  be required to reimburse the then existing or prior Note Holders for
  payments made pursuant to Section 5.03 hereof (to the extent not
  previously reimbursed) shall be distributed to such then existing or
  prior Note Holders ratably, without priority of one over the other, in
  accordance with the amount of the payment or payments made by each such
  then existing or prior Note Holder pursuant to said Section 5.03 hereof;

            Third, (i)  so much of such payments or amounts remaining as
  shall be required to pay in full the aggregate unpaid Principal Amount of
  all Series G Equipment Notes, and the accrued but unpaid interest and
  other amounts due thereon and all other Secured Obligations in respect of
  the Series G Equipment Notes to the date of distribution, shall be
  distributed to the Note Holders of Series G, and in case the aggregate
  amount so to be distributed shall be insufficient to pay in full as
  aforesaid, then ratably, without priority of one over the other, in the
  proportion that the aggregate unpaid Principal Amount of all Series G
  Equipment Notes held by each holder plus the accrued but unpaid interest
  and other amounts due hereunder or thereunder to the date of
  distribution, bears to the aggregate unpaid Principal Amount of all
  Series G Equipment Notes held by all such holders plus the accrued but
  unpaid interest and other amounts due thereon to the date of
  distribution; and (ii) after giving effect to paragraph (i) above, so
  much of such payments or amounts remaining as shall be required to pay in
  full the aggregate unpaid Principal Amount of all Series C Equipment
  Notes, and the accrued but unpaid interest and other amounts due thereon
  and all other Secured Obligations in respect of the Series C Equipment
  Notes to the date of distribution, shall be distributed to the Note
  Holders of Series C, and in case the aggregate amount so to be
  distributed shall be insufficient to pay in full as aforesaid, then
  ratably, without priority of one over the other, in the proportion that
  the aggregate unpaid Principal Amount of all Series C Equipment Notes
  held by each holder plus the accrued but unpaid interest and other
  amounts due hereunder or thereunder to the date of distribution, bears to
  the aggregate unpaid Principal Amount of all Series C Equipment Notes
  held by all such holders plus the accrued but unpaid interest and other
  amounts due thereon to the date of distribution;  and

            Fourth,  the balance, if any, of such payments or amounts
  remaining thereafter shall be distributed to the Owner Trustee free and
  clear of the Lien of this Indenture.

            No Make-Whole Amount shall be due and payable on the Equipment
  Notes as a consequence of the acceleration of the Equipment Notes.

            SECTION 3.04.   Certain Payments.

            (a)  Any payments received by the Indenture Trustee for which
  no provision as to the application thereof is made in this Trust
  Indenture and for which such provision is made in the Lease, the
  Participation Agreement or any other Operative Document shall be applied
  forthwith to the purpose for which such payment was made in accordance
  with the terms of the Lease, the Participation Agreement or such other
  Operative Document, as the case may be.

            (b)  The Indenture Trustee will distribute promptly upon

  or any other Indenture Indemnitees, (ii) any Note Holder, (iii) the
  Subordination Agent, (iv) the Liquidity Provider, (v) the Policy Provider
  and (vi) the Pass Through Trustees, in each case whether pursuant to
  Section 6 of the Participation Agreement or as Supplemental Rent,

  Indenture Trustee under the third paragraph of Section 2.02 shall be
  distributed to the Subordination Agent to be distributed in accordance
  with the terms of the Intercreditor Agreement.

            (c)  Notwithstanding anything to the contrary contained in this
  Article III, any amounts received by the Indenture Trustee which
  constitute Excluded Payments shall be distributed promptly upon receipt
  by the Indenture Trustee directly to the Person or Persons entitled
  thereto.

            (d)  Notwithstanding any provision of this Trust Indenture to
  the contrary, any amounts held by the Indenture Trustee that would, but
  for the provisions of Section 3.03 hereof, otherwise be distributed to
  Lessee shall, notwithstanding the provisions of said Section, be
  distributed to Lessee unless and until a Lease Event of Default shall
  have occurred and be continuing.

            SECTION 3.05.   Other Payments.

            Any payments received by the Indenture Trustee for which no
  provision as to the application thereof is made in the Lease, the
  Participation Agreement, elsewhere in this Trust Indenture or in any
  other Operative Document shall be distributed by the Indenture Trustee to
  the extent received or realized at any time (i) prior to the payment in
  full of all Secured Obligations due the Note Holders, in the order of
  priority specified in Section 3.01 hereof subject to the proviso thereto,
  and (ii) after payment in full of all Secured Obligations due the Note
  Holders, in the following order of priority:

            First,   to the extent payments or amounts described in clause
  "First" of Section 3.03 hereof are otherwise obligations of Lessee under
  the Operative Documents or for which Lessee is obligated to indemnify
  against thereunder, in the manner provided in clause "First" of Section
  3.03 hereof, and

            Second,  in the manner provided in clause "Fourth" of Section

  Further, and except as otherwise provided in Sections 3.02, 3.03 and 3.04
  hereof, all payments received and amounts realized by the Indenture
  Trustee under the Lease or otherwise with respect to the Aircraft
  (including, without limitation, all amounts realized upon the sale or
  release of the Aircraft after the termination of the Lease with respect
  thereto), to the extent received or realized at any time after payment in
  full of all Secured Obligations due the Note Holders, shall be
  distributed by the Indenture Trustee in the order of priority specified
  in clause (ii) of the immediately preceding sentence of this Section
  3.05.

            SECTION 3.06.   Payments to Owner Trustee.

            Any amounts distributed hereunder by the Indenture Trustee to

  type received by the Indenture Trustee at such office and to such account
  or accounts of such entity or entities as shall be designated by notice
  from the Owner Trustee to the Indenture Trustee from time to time.  The
  Owner Trustee hereby notifies the Indenture Trustee that unless and until
  the Indenture Trustee receives notice to the contrary from the Owner
  Trustee, all amounts to be distributed to the Owner Trustee pursuant to
  clause "Second" of Section 3.01 hereof shall be distributed by wire
  transfer of funds of the type received by the Indenture Trustee to the
  Owner Participant's account (within the time limits contemplated by
  Section 2.04(a)) specified in Schedule I to the Participation Agreement.

                                 ARTICLE IV

                   COVENANTS OF OWNER TRUSTEE; EVENTS OF
                   DEFAULT; REMEDIES OF INDENTURE TRUSTEE

            SECTION 4.01.   Covenants of Owner Trustee.

            The Owner Trustee hereby covenants and agrees as follows:

            (a)  the Owner Trustee will duly and punctually pay the
  Principal Amount of, Make-Whole Amount, if any, and interest on and other
  amounts due under the Equipment Notes and hereunder in accordance with
  the terms of the Equipment Notes and this Trust Indenture and all
  amounts, if any, payable by it to the Note Holders under the
  Participation Agreement;

            (b)  [Reserved]

            (c)  in the event the Owner Trustee shall have Actual Knowledge
  of  an Event of Default, a Default or an Event of Loss, the Owner Trustee
  will give prompt written notice of such Event of Default, Default or
  Event of Loss to the Indenture Trustee, each Note Holder, Lessee and the
  Owner Participant;

            (d)  the Owner Trustee will furnish to the Indenture Trustee,
  promptly upon receipt thereof, duplicates or copies of all reports,
  notices, requests, demands, certificates and other instruments furnished
  to the Owner Trustee under the Lease, including, without limitation, a
  copy of any Termination Notice received pursuant to Section 9(a) of the
  Lease, a copy of each notice delivered pursuant to Section 10, 19 or 20
  of the Lease and a copy of each report or notice received pursuant to
  Section 11(c) of the Lease to the extent that the same shall not be
  required to have been furnished to the Indenture Trustee pursuant to the
  Lease;

            (e)  except pursuant to the Operative Documents or with the
  consent of the Indenture Trustee (acting pursuant to instructions given
  in accordance with Section 9.01 hereof), the Owner Trustee will not
  contract for, create, incur, assume or suffer to exist any Debt, and will
  not guarantee (directly or indirectly or by an instrument having the
  effect of assuring another's payment or performance on any obligation or
  capability of so doing, or otherwise), endorse or otherwise be or become
  contingently liable, directly or indirectly, in connection with the Debt
  of any other Person; and

            (f)  the Owner Trustee will not enter into any business or
  other activity other than the business of owning the Aircraft, the
  leasing thereof to Lessee and the carrying out of the transactions
  contemplated hereby and by the Lease, the Participation Agreement, the
  Trust Agreement and the other Operative Documents.

            SECTION 4.02.   Event of Default.

            "Event of Default" means any of the following events (whatever
  the reason for such Event of Default and whether such event shall be
  voluntary or involuntary or come about or be effected by operation of Law
  or pursuant to or in compliance with any judgment, decree or order of any
  court or any order, rule or regulation of any administrative or
  governmental body):

            (a)  any Lease Event of Default (provided that any such Lease
  Event of Default caused solely by a failure of Lessee to pay to the Owner
  Trustee or the Owner Participant when due any amount that is included in
  the definition of Excluded Payments shall not constitute an Event of
  Default unless notice is given by the Owner Trustee to the Indenture
  Trustee that such failure shall constitute an Event of Default); or

            (b)  the failure of the Owner Trustee to pay when due any
  payment of Principal Amount of, interest on, Make-Whole Amount, if any,
  or other amount due and payable under any Equipment Note or hereunder
  (other than any such failure arising as a result of a Lease Event of
  Default or a Lease Default) and such failure shall have continued
  unremedied for ten (10) Business Days in the case of any payment of
  Principal Amount or interest or Make-Whole Amount, if any, thereon and,
  in the case of any other amount, for ten (10) Business Days after the
  Owner Trustee or the Owner Participant receives written demand from the
  Indenture Trustee or any Note Holder; or

            (c)  any Lien required to be discharged by the Owner Trustee in
  its individual or trust capacity pursuant to Section 7(f) of the
  Participation Agreement, or by the Owner Participant pursuant to Section
  7(f) of the Participation Agreement shall remain undischarged for a
  period of thirty (30) days after the Owner Trustee and the Owner
  Participant shall have received written notice from the Indenture Trustee
  or any Note Holder of such Lien; or

            (d)  any representation or warranty made by the Owner
  Participant or the Owner Trustee herein, in the Participation Agreement
  or in any certificate furnished by the Owner Participant or the Owner
  Trustee to the Indenture Trustee or any Note Holder in connection with
  the transactions contemplated by the Operative Documents shall prove to
  have been false or incorrect when made in any material respect and
  continues to be material and adverse to the interests of the Indenture
  Trustee or the Note Holders; and if such misrepresentation is capable of
  being corrected and if such correction is being sought diligently, such
  misrepresentation shall not have been corrected within sixty (60) days
  (or, without affecting Section 4.02(f) hereof, in the case of the
  representations made in Section 7(a) of the Participation Agreement as to
  the citizenship of the Owner Trustee in its individual capacity [or of
  the Owner Participant, respectively,](4) as soon as is reasonably
  practicable but in any event within sixty (60) days following notice
  thereof from the Indenture Trustee or any Note Holder to the Owner
  Trustee or the Owner Participant, as the case may be); or

            (e)  other than as provided in (c) above or (f) below, any
  failure by the Owner Trustee or Owner Participant to observe or perform
  any other covenant or obligation of the Owner Trustee or Owner
  Participant, as the case may be, for the benefit of the Indenture Trustee
  or the Note Holders contained in the Participation Agreement, Section
  4.01(a) of the Trust Agreement, the Equipment Notes or this Trust
  Indenture which is not remedied within a period of sixty (60) days after
  notice thereof has been given to the Owner Trustee and the Owner
  Participant; or

            (f)  if at any time when the Aircraft is registered under the
  laws of the United States, the Owner Participant shall not be a Citizen
  of the United States, and as the result thereof the registration of the
  Aircraft under the Transportation Code, and regulations then applicable
  thereunder, shall cease to be effective; provided that no Event of
  Default shall be deemed to have occurred under this paragraph (f) unless
  such circumstances continue unremedied for more than sixty (60) days
  after the Owner Participant has Actual Knowledge of the state of facts
  that resulted in such ineffectiveness and of such loss of citizenship; or

            (g)  at any time either (i) the commencement of an involuntary
  case or other proceeding in respect of the Owner Participant, the Owner
  Trustee or the Trust Estate under the federal bankruptcy Laws, as now
  constituted or hereafter amended, or any other applicable federal or
  state bankruptcy, insolvency or other similar Law in the United States or
  seeking the appointment of a receiver, liquidator, assignee, custodian,
  trustee, sequestrator (or similar official) of the Owner Participant, the
  Owner Trustee or the Trust Estate or for all or substantially all of its
  property, or seeking the winding-up or liquidation of its affairs and the
  continuation of any such case or other proceeding undismissed and
  unstayed for a period of ninety (90) consecutive days; or (ii) the
  commencement by the Owner Participant, the Owner Trustee or the Trust
  Estate of a voluntary case or proceeding under the federal bankruptcy
  Laws, as now constituted or hereafter amended, or any other applicable
  federal or state bankruptcy, insolvency or other similar Law in the
  United States, or the consent by the Owner Participant, the Owner Trustee
  or the Trust Estate to the appointment of or taking possession by a
  receiver, liquidator, assignee, trustee, custodian, sequestrator (or
  other similar official) of the Owner Participant, the Owner Trustee or
  the Trust Estate or for all or substantially all of its property, or the
  making by the Owner Participant, the Owner Trustee or the Trust Estate of
  any assignment for the benefit of creditors or the Owner Participant or
  the Owner Trustee shall take any action to authorize any of the
  foregoing; provided, however, that an event referred to in this Section
  4.02(g) with respect to the Owner Participant shall not constitute an
  Event of Default if within thirty (30) days of the commencement of the
  case or proceeding a final non-appealable order, judgement or decree
  shall be entered in such case or proceeding by a court or a trustee,
  custodian, receiver or liquidator, to the effect that no part of the
  Trust Estate (except for the Owner Participant's beneficial interest
  therein) and no right, title or interest under the Trust Indenture Estate
  shall be included in, or be subject to, any declaration or adjudication
  of, or proceedings with respect to, the bankruptcy, insolvency or
  liquidation of the Owner Participant referred to in this Section 4.02(g).

            SECTION 4.03.   Certain Rights.

            The Indenture Trustee shall give the Note Holders, the Owner
  Trustee and the Owner Participant prompt written notice of any Event of
  Default of which the Indenture Trustee has Actual Knowledge and, if any
  such Event of Default results from a Lease Event of Default, shall give
  the Note Holders, the Owner Trustee and the Owner Participant not less
  than ten (10) Business Days prior written notice of the date (the
  "Enforcement Date") on or after which the Indenture Trustee may (subject
  to the notice provision set forth in Section 4.04(a)) commence and
  consummate the exercise of any remedy or remedies described in Section
  4.04, 4.05 or 4.06 hereof, or the exercise of any remedy or remedies
  pursuant to the provisions of Section 15 of the Lease; provided, however,
  that in the event the Indenture Trustee shall have validly terminated the
  Lease (or, in the event of a reorganization proceeding involving Lessee
  instituted under Chapter 11 of the Bankruptcy Code, such Lease is
  rejected), the Indenture Trustee shall not, without the consent of the
  Owner Participant, sell or lease, or otherwise afford the use of, the
  Aircraft or any portion thereof to Lessee or any Affiliate thereof.
  Without limiting the generality of the foregoing, the Indenture Trustee
  shall give the Owner Trustee, the Owner Participant and Lessee at least
  ten (10) Business Days prior written notice (which may be given
  concurrently with notice of the Enforcement Date) of any declaration of
  the Lease to be in default pursuant to Sections 14 and 15 of the Lease or
  any termination of the Lease.  If an Event of Default shall have occurred
  and be continuing, the Owner Trustee shall have the following rights
  hereunder, any of which may be exercised directly by the Owner
  Participant.

            If as a result of the occurrence of an Event of Default in
  respect of the nonpayment by Lessee of Basic Rent due under the Lease,
  the Indenture Trustee shall have insufficient funds to make any payment
  of Principal Amount and interest on any Equipment Note on the day it
  becomes due and payable, the Owner Trustee or the Owner Participant may,
  but shall not be obligated to, pay the Indenture Trustee prior to the
  Enforcement Date, in the manner provided in Section 2.04 hereof, for
  application in accordance with Section 3.01 hereof, an amount equal to
  the portion of the Principal Amount and interest (including interest, if
  any, on any overdue payments of such portion of Principal Amount and
  interest) then due and payable on the Equipment Notes, and, unless the
  Owner Trustee has cured Events of Default in respect of payments of Basic
  Rent on each of the three (3) immediately preceding Basic Rent payment
  dates, or the Owner Trustee has cured six (6) previous Events of Default
  in respect of payments of Basic Rent, such payment by the Owner Trustee
  shall, solely for purposes of this Trust Indenture, be deemed to cure any
  Event of Default which would otherwise have arisen on account of the
  nonpayment by Lessee of such installment of Basic Rent (but not any other
  Default or Event of Default which shall have occurred and be continuing).

            If any Event of Default (other than in respect of the
  nonpayment of Basic Rent by Lessee) which can be cured by the payment of
  money has occurred, the Owner Trustee or the Owner Participant may, but
  shall not be obligated to, cure such Event of Default by making such
  payment prior to the Enforcement Date as is necessary to accomplish the
  observance or performance of the defaulted covenant, condition or
  agreement.

            Except as hereinafter in this Section 4.03 provided, the Owner
  Trustee shall not, as a result of exercising the right to cure any such
  Event of Default, obtain any Lien on any of the Mortgaged Property or any
  Rent payable under the Lease for or on account of costs or expenses
  incurred in connection with the exercise of such right, nor shall any
  claim of the Owner Trustee against Lessee or any other party for the
  repayment of such costs or expenses impair the prior right and security
  interest of the Indenture Trustee in and to the Mortgaged Property.  Upon
  any payment by the Owner Trustee or the Owner Participant pursuant to the
  first or second preceding paragraphs of this Section 4.03, the Owner
  Trustee or the Owner Participant, as the case may be, shall be subrogated
  to the rights of the Indenture Trustee and the Note Holders in respect of
  the Basic Rent which was overdue at the time of such payment and interest
  payable by Lessee on account of its being overdue and any Supplemental
  Rent in respect of the reimbursement of amounts paid by Owner Trustee
  pursuant to the immediately preceding paragraph (but in either case shall
  have no rights as a secured party hereunder), and thereafter, the Owner
  Trustee or the Owner Participant, as the case may be, shall be entitled
  to receive such overdue Basic Rent or Supplemental Rent, as the case may
  be, and interest thereon upon receipt thereof by the Indenture Trustee
  (and shall be entitled to bring an action against Lessee to enforce such
  payment); provided, however, that (i) if the Principal Amount and
  interest on the Equipment Notes shall have become due and payable
  pursuant to Section 4.04(b) hereof (and such acceleration shall not have
  been rescinded pursuant to Section 4.04(b)), such subrogation shall,
  until the Principal Amount of, interest on, Make-Whole Amount, if any,
  and all other amounts due with respect to all Equipment Notes shall have
  been paid in full, be subordinate to the rights of the Indenture Trustee,
  the Indenture Indemnitees and the Note Holders in respect of such payment
  of overdue Basic Rent, Supplemental Rent and such interest and (ii) the
  Owner Trustee shall not be entitled to seek to recover any such payment
  (or any payment in lieu thereof) except pursuant to the foregoing right
  of subrogation by demand or suit for damages.

            SECTION 4.04.   Remedies.

            (a)  Subject to the provisions of Section 2.14 hereof, if an
  Event of Default shall have occurred and be continuing and so long as the
  same shall continue unremedied, then and in every such case the Indenture
  Trustee may, subject to the second paragraph of this Section 4.04(a), on
  and after the Enforcement Date if such Event of Default results from a
  Lease Event of Default, exercise any or all of the rights and powers and
  pursue any and all of the remedies pursuant to this Article IV and shall
  have and may exercise all of the rights and remedies of a secured party
  under the Uniform Commercial Code in effect in the State of New York and,
  in the event such Event of Default is also a Lease Event of Default, any
  and all of the remedies pursuant to Section 15 of the Lease and may take
  possession of all or any part of the properties covered or intended to be
  covered by the Lien created hereby or pursuant hereto and may exclude the
  Owner Participant, the Owner Trustee and Lessee and all Persons claiming
  under any of them wholly or partly therefrom, provided, that (x) in the
  case of a sale of the Aircraft, the Indenture Trustee shall give the
  Owner Trustee and the Owner Participant, subsequent to the earlier of (I)
  the expiration of the Section 1110 Period (as hereinafter defined) and
  (II) Lessee's rejection of the Lease in a proceeding instituted under
  Chapter 11 of the Bankruptcy Code, twenty (20) days prior written notice
  of its intention to sell the Aircraft and (y) in the case of any judicial
  proceeding to foreclose the Lien of the Indenture, fifteen (15) days
  prior written notice of its intention to initiate such proceeding and,
  provided, further, that in the event the Indenture Trustee shall have
  validly terminated the Lease (or, in the event of a reorganization
  proceeding involving Lessee instituted under Chapter 11 of the Bankruptcy
  Code, such Lease is rejected), the Indenture Trustee shall not, without
  the consent of the Owner Participant, sell or lease, or otherwise afford
  the use of, the Aircraft or any portion thereof to Lessee or any
  affiliate thereof.  Unless an Event of Default not resulting from or
  relating to a Lease Event of Default has occurred and is continuing, the
  Owner Participant may bid at any public sale and become the purchaser.
  Without limiting any of the foregoing, it is understood and agreed that
  the Indenture Trustee may exercise any right of sale of the Aircraft
  available to it, even though it shall not have taken possession of the
  Aircraft and shall not have possession thereof at the time of such sale.

                 Anything in this Trust Indenture to the contrary
  notwithstanding, the Indenture Trustee shall not be entitled to exercise
  any remedy hereunder as a result of an Event of Default which arises
  solely by reason of one or more events or circumstances which constitute
  a Lease Event of Default unless the Indenture Trustee as security
  assignee of the Owner Trustee shall have (i) accelerated the maturity of
  the Equipment Notes and (ii) exercised or concurrently be exercising one
  or more of the remedies provided for in Section 15 of the Lease to
  terminate the Lease (in the event that it is not commercially reasonable
  to take possession of the Aircraft) or take possession and/or sell the
  Aircraft; provided, however, that such requirement to exercise one or
  more of such remedies under the Lease shall not apply in circumstances
  where the Indenture Trustee is, and has been, for a continuous period in
  excess of sixty (60) days subsequent to the entry of an order for relief
  or such other period as may be specified in Section 1110(a)(1)(A) of the
  Bankruptcy Code (such 60-day or other period being the "Section 1110
  Period"), involuntarily stayed or prohibited by applicable law or court
  order from exercising such remedies under the Lease (a "Continuous Stay
  Period"); provided further, however, that the requirement to exercise one
  or more of such remedies under the Lease shall nonetheless be applicable
  during a Continuous Stay Period subsequent to the expiration of the
  Section 1110 Period to the extent that the continuation of such
  Continuous Stay Period subsequent to the expiration of the Section 1110
  Period (A) results from an agreement by the trustee or the debtor-in-
  possession in such proceeding during the Section 1110 Period with the
  approval of the relevant court to perform the Lease in accordance with
  Section 1110(a)(1)(A) of the Bankruptcy Code and Lessee continues to
  perform as required by Section 1110(a)(1)(A-B) of the Bankruptcy Code or
  (B) is an extension of the Section 1110 Period with the consent of the
  Indenture Trustee pursuant to Section 1110(b) of the Bankruptcy Code or
  (C) results from Lessee's assumption during the Section 1110 Period with
  the approval of the relevant court of the Lease pursuant to Section 365
  of the Bankruptcy Code or (D) is the consequence of the Indenture
  Trustee's own failure to give any requisite notice to any Person.  In the
  event that the applicability of Section 1110 of the Bankruptcy Code to
  the Aircraft is being contested by Lessee in judicial proceedings, both
  the Indenture Trustee and the Owner Trustee shall have the right to
  participate in such proceedings.

                 It is expressly understood and agreed that, subject only
  to the immediately preceding paragraph, the inability, described in such
  paragraph, of the Indenture Trustee to exercise any right or remedy under
  the Lease shall in no event and under no circumstances prevent the
  Indenture Trustee from exercising any or all of its rights, powers and
  remedies under this Trust Indenture, including, without limitation, this
  Article IV.

            (b)  If an Event of Default shall have occurred and be
  continuing, then and in every such case the Indenture Trustee may (and
  shall, upon receipt of a written demand therefor from a Majority in
  Interest of Note Holders), subject to Section 4.03 hereof, at any time,
  by delivery of written notice or notices to the Owner Trustee and the
  Owner Participant, declare all the Equipment Notes to be due and payable,
  whereupon the unpaid Principal Amount of all Equipment Notes then
  outstanding, together with accrued but unpaid interest thereon (without
  Make-Whole Amount) and other amounts due thereunder, shall immediately
  become due and payable without presentment, demand, protest or notice,
  all of which are hereby waived; provided that if an Event of Default
  referred to in clause (g) of Section 4.02 hereof shall have occurred and
  be continuing or a Lease Event of Default under Section 14(e) of the
  Lease shall have occurred and be continuing, then and in every such case
  the unpaid Principal Amount then outstanding, together with accrued but
  unpaid interest and all other amounts due thereunder and hereunder shall
  immediately and without further act become due and payable without
  presentment, demand, protest or notice, all of which are hereby waived;
  provided further that in the event of a reorganization proceeding
  involving Lessee instituted under Chapter 11 of the Bankruptcy Code, if
  no other Lease Event of Default and no other Event of Default (other than
  the failure to pay the Principal Amount of the Equipment Notes which by
  such declaration have become payable) exists at any time after the
  consummation of such proceeding, such declaration shall be automatically
  rescinded without any further action on the part of any Note Holder.

                 This Section 4.04(b), however, is subject to the condition
  that, if at any time after the Principal Amount of the Equipment Notes
  shall have become so due and payable, and before any judgment or decree
  for the payment of the money so due, or any thereof, shall be entered,
  all overdue payments of interest upon the Equipment Notes and all other
  amounts payable under the Equipment Notes (except the Principal Amount of
  the Equipment Notes which by such declaration shall have become payable)
  shall have been duly paid, and every other Default and Event of Default
  with respect to any covenant or provision of this Trust Indenture shall
  have been cured, then and in every such case a Majority in Interest of
  Note Holders may (but shall not be obligated to), by written instrument
  filed with the Indenture Trustee, rescind and annul the Indenture
  Trustee's declaration and its consequences; but no such rescission or
  annulment shall extend to or affect any subsequent Default or Event of
  Default or impair any right consequent thereon.

            Any acceleration pursuant to this Section 4.04(b) shall be
  automatically rescinded and any related declaration of an Event of
  Default annulled in the event that the Owner Trustee shall have cured, in
  accordance with Section 4.03 hereof, the Event of Default that resulted
  in such acceleration or declaration.

            (c)  Any Note Holder shall be entitled, at any sale pursuant to
  Section 15 of the Lease or this Section 4.04, to credit against any
  purchase price bid at such sale by such holder all or any part of the
  unpaid obligations owing to such Note Holder and secured by the Lien of
  this Trust Indenture (but only to the extent that such purchase price
  would have been paid to such Note Holder pursuant to Article III hereof
  if such purchase price were paid in cash and the foregoing provisions of
  this subsection (c) were not given effect).

            (d)  In the event of any sale of the Trust Indenture Estate, or
  any part thereof, pursuant to any judgment or decree of any court or
  otherwise in connection with the enforcement of any of the terms of this
  Trust Indenture, the unpaid Principal Amount of all Equipment Notes then
  outstanding, together with accrued interest thereon, and other amounts
  due thereunder, shall immediately become due and payable without
  presentment, demand, protest or notice, all of which are hereby waived.

            (e)  Notwithstanding anything contained herein, so long as the
  Pass Through Trustee under any Pass Through Trust Agreement or the
  Subordination Agent on its behalf is a Note Holder, the Indenture Trustee
  will not be authorized or empowered to acquire title to any Mortgaged
  Property or take any action with respect to any Mortgaged Property so
  acquired by it if such acquisition or action would cause any Pass Through
  Trust to fail to qualify as a "grantor trust" for federal income tax
  purposes.

            SECTION 4.05.   Return of Aircraft, Etc.

            (a)  If an Event of Default shall have occurred and be
  continuing, subject to Sections 4.03 and 4.04 hereof and unless the Owner
  Trustee or the Owner Participant shall have elected to purchase the
  Equipment Notes, at the request of the Indenture Trustee, the Owner
  Trustee shall promptly execute and deliver to the Indenture Trustee such
  instruments and other documents as the Indenture Trustee may deem
  necessary or advisable to enable the Indenture Trustee or an agent or
  representative designated by the Indenture Trustee, at such time or times
  and place or places as the Indenture Trustee may specify, to obtain
  possession of all or any part of the Mortgaged Property included in the
  Trust Indenture Estate to which the Indenture Trustee shall at the time
  be entitled hereunder.  If the Owner Trustee shall for any reason fail to
  execute and deliver such instruments and documents after such request by
  the Indenture Trustee, the Indenture Trustee may (i) obtain a judgment
  conferring on the Indenture Trustee the right to immediate possession and
  requiring the Owner Trustee to execute and deliver such instruments and
  documents to the Indenture Trustee, to the entry of which judgment the
  Owner Trustee hereby specifically consents to the fullest extent
  permitted by applicable law, and (ii) pursue all or part of such
  Mortgaged Property wherever it may be found and, in the event that a
  Lease Event of Default has occurred and is continuing, may enter any of
  the premises of Lessee wherever such Mortgaged Property may be or be
  supposed to be and search for such Mortgaged Property and take possession
  of and remove such Mortgaged Property. All expenses of obtaining such
  judgment or of pursuing, searching for and taking such property shall,
  until paid, be secured by the Lien of this Trust Indenture.

            (b)  Upon every such taking of possession, the Indenture
  Trustee may, from time to time, at the expense of the Mortgaged Property,
  make all such expenditures for maintenance, use, operation, storage,
  insurance, leasing, control, management, disposition, modifications or
  alterations to and of the Mortgaged Property, as it may deem proper.  In
  each such case, the Indenture Trustee shall have the right to maintain,
  use, operate, store, insure, lease, control, manage, dispose of, modify
  or alter the Mortgaged Property and to carry on the business and to
  exercise all rights and powers of the Owner Participant and the Owner
  Trustee relating to the Mortgaged Property, as the Indenture Trustee
  shall deem best, including the right to enter into any and all such
  agreements with respect to the maintenance, use, operation, storage,
  insurance, leasing, control, management, disposition, modification or
  alteration of the Mortgaged Property or any part thereof as the Indenture
  Trustee may determine, and the Indenture Trustee shall be entitled to
  collect and receive directly all tolls, rents (including Rent), revenues,
  issues, income, products and profits of the Mortgaged Property and every
  part thereof, except Excluded Payments, without prejudice, however, to
  the right of the Indenture Trustee under any provision of this Trust
  Indenture to collect and receive all cash held by, or required to be
  deposited with, the Indenture Trustee hereunder other than Excluded
  Payments.  Such tolls, rents (including Rent), revenues, issues, income,
  products and profits shall be applied to pay the expenses of the
  maintenance, use, operation, storage, insurance, leasing, control,
  management, disposition, improvement, modification or alteration of the
  Mortgaged Property and of conducting the business thereof, and to make
  all payments which the Indenture Trustee may be required or may elect to
  make, if any, for taxes, assessments, insurance or other proper charges
  upon the Mortgaged Property or any part thereof (including the employment
  of engineers and accountants to examine, inspect and make reports upon
  the properties and books and records of the Owner Trustee), and all other
  payments which the Indenture Trustee may be required or authorized to
  make under any provision of this Trust Indenture, as well as just and
  reasonable compensation for the services of the Indenture Trustee, and of
  all Persons properly engaged and employed by the Indenture Trustee with
  respect hereto.

            SECTION 4.06.   Remedies Cumulative.

            Each and every right, power and remedy given to the Indenture
  Trustee specifically or otherwise in this Trust Indenture shall be
  cumulative and shall be in addition to every other right, power and
  remedy herein specifically given or now or hereafter existing at law, in
  equity or by statute, and each and every right, power and remedy whether
  specifically herein given or otherwise existing may be exercised from
  time to time and as often and in such order as may be deemed expedient by
  the Indenture Trustee, 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 Indenture Trustee 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 Owner Trustee or Lessee or to be an
  acquiescence therein.

            SECTION 4.07.   Discontinuance of Proceedings.

            In case the Indenture Trustee shall have instituted any
  proceeding to enforce any right, power or remedy under this Trust
  Indenture by foreclosure, entry or otherwise, and such proceedings shall
  have been discontinued or abandoned for any reason or shall have been
  determined adversely to the Indenture Trustee, then and in every such
  case the Owner Trustee, the Indenture Trustee and Lessee shall, subject
  to any determination in such proceedings, be restored to their former
  positions and rights hereunder with respect to the Mortgaged Property,
  and all rights, remedies and powers of the Owner Trustee, the Indenture
  Trustee or Lessee shall continue as if no such proceedings had been
  instituted.

            SECTION 4.08.   Waiver of Past Defaults.

            Upon written instruction from a Majority in Interest of Note
  Holders, and subject to Section 5.02 the Indenture Trustee shall waive
  any past Default hereunder and its consequences and upon any such waiver
  such Default shall cease to exist and any Event of Default arising
  therefrom shall be deemed to have been cured for every purpose of this
  Trust Indenture, but no such waiver shall extend to any subsequent or
  other Default or impair any right consequent thereon; provided, that in
  the absence of written instructions from all the Note Holders, the
  Indenture Trustee shall not waive any Default (i) in the payment of the
  Principal Amount, Make-Whole Amount, if any, and interest and other
  amounts due under any Equipment Note then outstanding, or (ii) in respect
  of a covenant or provision hereof which, under Article IX hereof, cannot
  be modified or amended without the consent of each Note Holder.

            SECTION 4.09.   Appointment of Receiver.

            If an Event of Default shall have occurred and be continuing,
  the Indenture Trustee shall, as a matter of right, be entitled to the
  appointment of a receiver (who may be the Indenture Trustee or any
  successor or nominee thereof) for all or any part of the Mortgaged
  Property, whether such receivership be incidental to a proposed sale of
  the Mortgaged Property or the taking of possession thereof or otherwise,
  and the Owner Trustee hereby consents to the appointment of such a
  receiver and will not oppose any such appointment. Any receiver appointed
  for all or any part of the Mortgaged Property shall be entitled to
  exercise all the rights and powers of the Indenture Trustee with respect
  to the Mortgaged Property.

            SECTION 4.10.   Indenture Trustee Authorized to Execute Bills
  of Sale, Etc.

            The Owner Trustee irrevocably appoints the Indenture Trustee
  the true and lawful attorney-in-fact of the Owner Trustee in its name and
  stead and on its behalf, for the purpose, if an Event of Default shall
  have occurred and be continuing, of effectuating in accordance with
  applicable law any sale, assignment, transfer or delivery for the
  enforcement of the Lien of this Trust Indenture, whether pursuant to
  foreclosure or power of sale, assignments and other instruments as may be
  necessary or appropriate, with full power of substitution, the Owner
  Trustee hereby ratifying and confirming all that such attorney or any
  substitute shall do by virtue hereof in accordance with applicable law.
  Nevertheless, if so requested by the Indenture Trustee or any purchaser,
  the Owner Trustee shall ratify and confirm any such sale, assignment,
  transfer or delivery, by executing and delivering to the Indenture
  Trustee or such purchaser all bills of sale, assignments, releases and
  other proper instruments to effect such ratification and confirmation as
  may be designated in any such request.

            SECTION 4.11.   Rights of Note Holders to Receive Payment.

            Notwithstanding any other provision of this Trust Indenture,
  the right of any Note Holder to receive payment of principal of, and
  Make-Whole Amount, if any, and interest on an Equipment Note on or after
  the respective due dates expressed in such Equipment Note, or to bring
  suit for the enforcement of any such payment on or after such respective
  dates in accordance with the terms hereof, shall not be impaired or
  affected without the consent of such Note Holder.

                                 ARTICLE V

                      DUTIES OF THE INDENTURE TRUSTEE

            SECTION 5.01.   Notice of Event of Default.

            If the Indenture Trustee shall have Actual Knowledge of an
  Event of Default or of a Default arising from a failure to pay Rent, the
  Indenture Trustee shall give prompt written notice thereof to the Owner
  Trustee, the Owner Participant, Lessee and each Note Holder.  Subject to
  the terms of Sections 2.14, 4.03, 4.04, 4.08, 5.02 and 5.03 hereof, the
  Indenture Trustee shall take such action, or refrain from taking such
  action, with respect to such Event of Default or Default (including with
  respect to the exercise of any rights or remedies hereunder) as the
  Indenture Trustee shall be instructed in writing by a Majority in
  Interest of Note Holders. Subject to the provisions of Section 5.03, if
  the Indenture Trustee shall not have received instructions as above
  provided within twenty (20) days after mailing notice of such Event of
  Default to the Note Holders, the Indenture Trustee may, subject to
  instructions thereafter received pursuant to the preceding provisions of
  this Section 5.01, take such action, or refrain from taking such action,
  but shall be under no duty to take or refrain from taking any action,
  with respect to such Event of Default or Default as it shall determine
  advisable in the best interests of the Note Holders.  If the Indenture
  Trustee shall at any time declare the Lease to be in default pursuant to
  Section 15 thereof or shall elect to foreclose or otherwise enforce this
  Trust Indenture, the Indenture Trustee shall forthwith notify the Owner
  Participant, the Note Holders, the Owner Trustee and Lessee.  For all
  purposes of this Trust Indenture, in the absence of Actual Knowledge on
  the part of the Indenture Trustee, the Owner Trustee or the Owner
  Participant, the Indenture Trustee, the Owner Trustee or the Owner
  Participant, as the case may be, shall not be deemed to have knowledge of
  a Default or an Event of Default (except, in the case of the Indenture
  Trustee, the failure of Lessee to pay any installment of Basic Rent
  within one (1) Business Day after the same shall become due, if any
  portion of such installment was then required to be paid to the Indenture
  Trustee, which failure shall constitute knowledge of a Default) unless
  notified in writing by Lessee, the Owner Trustee, the Owner Participant
  or one or more Note Holders.

            SECTION 5.02.   Action upon Instructions; Certain Rights and
  Limitations.

            (a)  Subject to the terms of Sections 2.14, 4.03, 4.04(a) and
  (b), 4.08, 5.01 and 5.03 hereof, upon the written instructions at any
  time and from time to time of a Majority in Interest of Note Holders, the
  Indenture Trustee shall, subject to the terms of this Section 5.02, take
  such of the following actions as may be specified in such instructions:
  (i) give such notice or direction or exercise such right, remedy or power
  hereunder as shall be specified in such instructions; (ii) give such
  notice or direction or exercise such right, remedy or power under the
  Lease, the Participation Agreement, the Purchase Agreement, or any other
  part of the Trust Indenture Estate as shall be specified in such
  instructions; and (iii) after the occurrence and during the continuance
  of an Event of Default, approve as satisfactory to the Indenture Trustee
  all matters required by the terms of the Lease to be satisfactory to the
  Owner Trustee, it being understood that without the written instructions
  of a Majority in Interest of Note Holders, the Indenture Trustee shall
  not approve any such matter as satisfactory to the Indenture Trustee;
  provided, that anything contained in this Trust Indenture, the Lease or
  the other Operative Documents to the contrary notwithstanding:

                     (1) the Owner Trustee or the Owner Participant may,
       without the consent of the Indenture Trustee, demand, collect, sue
       for or otherwise obtain all amounts included in Excluded Payments
       from Lessee, exercise any election or option or make any decision or
       determination or to give or receive any notice, consent, waiver or
       approval in respect of any Excluded Payment and seek legal or
       equitable remedies to require Lessee to maintain the insurance
       coverage referred to in Section 11 of the Lease; provided, that the
       rights referred to in this clause (1) shall not be deemed to include
       the exercise of any remedies provided for in Section 15 of the Lease
       other than the right to proceed by appropriate court action, either
       at law or in equity, to enforce payment by Lessee of such amounts
       included in Excluded Payments or performance by Lessee of such
       insurance covenant, or to recover damages for the breach thereof or
       for specific performance of any covenant of Lessee;

                     (2) the Indenture Trustee shall not, without the
       consent of the Owner Trustee and the Owner Participant, which
       consent shall not be withheld if no right or interest of the Owner
       Trustee or the Owner Participant shall be diminished or impaired
       thereby, (i) enter into, execute and deliver amendments,
       modifications, waivers or consents in respect of any of the
       provisions of the Lease or any other Operative Document, or (ii)
       approve any accountants, engineers, appraisers or counsel as
       satisfactory to render services for or issue opinions to the Owner
       Trustee pursuant to the Operative Documents;

                     (3) whether or not a Default or Event of Default under
       the Trust Indenture has occurred and is continuing, the Owner
       Trustee and the Owner Participant shall have the right, together
       with the Indenture Trustee, (i) to receive from Lessee all notices,
       certificates, reports, filings, opinions of counsel and other
       documents and all information which any thereof is permitted or
       required to give or furnish to the Owner Trustee or Lessor pursuant
       to any Operative Document, (ii) to exercise inspection rights
       pursuant to Section 12 of the Lease and (iii) to give notices of
       default under Section 14 of the Lease;

                     (4)  whether or not a Default or Event of Default
       under the Trust Indenture has occurred and is continuing, the Owner
       Trustee shall have the right to the exclusion of the Indenture
       Trustee to (i) adjust upwards Rent, EBO Amount and Termination
       Values as provided in Section 3(c) of the Lease, (ii) to extend the
       Term, (iii) to retain all rights with respect to insurance
       maintained for its own account which Section 11(b) of the Lease
       specifically confers on Lessor or the Owner Participant, (iv) to
       exercise, to the extent necessary to enable it to exercise its
       rights under Section 4.03 hereof, the rights of Lessor under Section
       22 of the Lease  and (v) to select counsel with respect to any
       opinion relating to tax matters to be delivered solely to the Owner
       Participant;

                     (5)  so long as no Indenture Trustee Event has
       occurred and is continuing, the Owner Trustee shall have the right,
       to the exclusion of the Indenture Trustee, to adjust EBO Amounts and
       Termination Values as provided in Section 3(c) of the Lease or to
       adjust downward any installment or amount of Basic Rent, EBO Amount
       or Termination Value, as such installments and amounts are set forth
       in Exhibits B, C and D, respectively, to the Lease, to the extent of
       the portion of such installment or amount that would, under Section
       3.01, 3.02 or 3.03 hereof, as the case may be, be distributable to
       the Owner Trustee or the Owner Participant;

                     (6)  whether or not a Default or Event of Default
       under the Trust Indenture has occurred and is continuing, the Owner
       Trustee may, without the consent of the Indenture Trustee, (i)
       solicit and make bids with respect to the Aircraft under Section 9
       of the Lease in respect of a termination of the Lease by Lessee
       pursuant to Section 9 thereof, (ii) determine "fair market sales
       value" and "fair market rental value" under Section 19 of the Lease
       for all purposes except following an Event of Default pursuant to
       Section 15 of the Lease, and (iii) make an election pursuant to and
       in accordance with the provisions of Section 9(b) of the Lease; and

                     (7)  so long as no Indenture Trustee Event shall have
       occurred and be continuing, except as provided in clauses (2) and
       (3) above, all other rights of the "Lessor" under the Lease shall be
       exercised by the Owner Trustee to the exclusion of the Indenture
       Trustee including, without limitation, the right to (i) exercise all
       rights with respect to Lessee's use and operation, modification or
       maintenance of the Aircraft and any Engine which the Lease
       specifically confers on Lessor, and (ii) consent to and approve any
       assignment pursuant to Section 13 of the Lease; provided that the
       foregoing shall not (A) limit any rights separately granted to the
       Indenture Trustee under the Operative Documents, (B) limit the right
       of the Indenture Trustee to receive any funds to be delivered to the
       "Lessor" under the Lease (except with respect to Excluded Payments)
       and under the Purchase Agreement or confer upon the Owner Trustee
       the right to adversely affect the validity or enforceability of the
       Lien of this Indenture by depriving the Note Holders or other
       Indenture Indemnitees of the benefit thereof or (C) confer on the
       Owner Trustee the right to agree to any amendment or supplement to
       the Lease except in accordance with Article IX.

            Notwithstanding anything to the contrary contained herein, the
  Indenture Trustee shall have the right, to the exclusion of the Owner
  Trustee and the Owner Participant, to (A) declare the Lease to be in
  default under Section 15 thereof and (B) subject only to the provisions
  of Sections 4.03, 4.04(a) and (b) and 2.14 hereof, exercise the remedies
  set forth in such Section 15 (other than in connection with Excluded
  Payments) at any time that a Lease Event of Default shall have occurred
  and be continuing.

            The Indenture Trustee will execute and the Owner Trustee will
  file or cause to be filed such continuation statements with respect to
  financing statements relating to the security interest created hereunder
  in the Trust Indenture Estate as specified by Lessee pursuant to Section
  7(d) of the Participation Agreement or as may be specified from time to
  time in written instructions of a Majority in Interest of Note Holders
  (which instructions may, by their terms, be operative only at a future
  date and which shall be accompanied by the form of such continuation
  statement so to be filed). The Indenture Trustee will furnish to each
  Note Holder (and, during the continuation of an Indenture Trustee Event,
  to the Owner Trustee and Owner Participant), promptly upon receipt
  thereof, duplicates or copies of all reports, notices, requests, demands,
  certificates and other instruments furnished to the Indenture Trustee
  under the Lease or hereunder, including, without limitation, a copy of
  any Termination Notice and a copy of each report or notice received
  pursuant to Sections 9(a) and 11(c) of the Lease, respectively, to the
  extent that the same shall not have been furnished to such Note Holder
  pursuant hereto or to the Lease.

            (b)  If any Lease Event of Default shall have occurred and be
  continuing and the Owner Trustee shall not have cured fully such Lease
  Event of Default under and in accordance with Section 4.03 hereof, on
  request of a Majority in Interest of Note Holders, the Indenture Trustee
  shall declare the Lease to be in default pursuant to Section 15 thereof
  and exercise those remedies specified by such Note Holders.  The
  Indenture Trustee agrees to provide to the Note Holders, the Owner
  Trustee, the Owner Participant and Lessee concurrently with such
  declaration by the Indenture Trustee, notice of such declaration by the
  Indenture Trustee.

            SECTION 5.03.   Indemnification.

            The Indenture Trustee shall not be required to take any action
  or refrain from taking any action under Sections 5.01 (other than the
  first sentence thereof), 5.02 or Article IV hereof unless the Indenture
  Trustee shall have been indemnified to its reasonable satisfaction
  against any liability, cost or expense (including counsel fees) which may
  be incurred in connection therewith pursuant to a written agreement with
  one or more Note Holders.  The Indenture Trustee shall not be under any
  obligation to take any action under this Trust Indenture and nothing
  herein or therein shall require the Indenture Trustee to expend or risk
  its own funds or otherwise incur the risk of any financial liability in
  the performance of any of its rights or powers if it shall have
  reasonable grounds for believing that repayment of such funds or adequate
  indemnity against such risk or liability is not reasonably assured to it
  (the written indemnity of any Note Holder who is a QIB, signed by an
  authorized officer thereof, in favor of, delivered to and in form
  reasonably satisfactory to Indenture Trustee shall be accepted as
  reasonable assurance of adequate indemnity).  The Indenture Trustee shall
  not be required to take any action under Section 5.01 (other than the
  first sentence thereof) or 5.02 or Article IV hereof, nor shall any other
  provision of this Trust Indenture or any other Operative Document be
  deemed to impose a duty on the Indenture Trustee to take any action, if
  the Indenture Trustee shall have been advised by counsel that such action
  is contrary to the terms hereof or of the Lease or is otherwise contrary
  to Law.

            SECTION 5.04.   No Duties Except as Specified in Trust
  Indenture or Instructions.

            The Indenture Trustee shall not have any duty or obligation to
  use, operate, store, lease, control, manage, sell, dispose of or
  otherwise deal with the Aircraft or any other part of the Trust Indenture
  Estate, or to otherwise take or refrain from taking any action under, or
  in connection with, this Trust Indenture or any part of the Trust
  Indenture Estate, except as expressly provided by the terms of this Trust
  Indenture or as expressly provided in written instructions from Note
  Holders as provided in this Trust Indenture; and no implied duties or
  obligations shall be read into this Trust Indenture against the Indenture
  Trustee.  The Indenture Trustee agrees that it will in its individual
  capacity and at its own cost and expense (but without any right of
  indemnity in respect of any such cost or expense under Section 7.01
  hereof), promptly take such action as may be necessary duly to discharge
  all liens and encumbrances on any part of the Trust Indenture Estate
  which result from claims against it in its individual capacity not
  related to the ownership of the Aircraft or the administration of the
  Trust Indenture Estate or any other transaction pursuant to this Trust
  Indenture or any document included in the Trust Indenture Estate.

            SECTION 5.05.   No Action Except Under Lease, Trust Indenture
  or Instructions.

            The Owner Trustee and the Indenture Trustee agree that they
  will not use, operate, store, lease, control, manage, sell, dispose of or
  otherwise deal with the Aircraft or any other part of the Trust Indenture
  Estate except (i) as required by the terms of the Lease or (ii) in
  accordance with the powers granted to, or the authority conferred upon,
  the Owner Trustee and the Indenture Trustee pursuant to this Trust
  Indenture and in accordance with the express terms hereof.

            SECTION 5.06.   Replacement Airframes and Replacement Engines.

            At any time an Airframe or Engine is to be replaced under or
  pursuant to Section 10 of the Lease by a Replacement Airframe or
  Replacement Engine, if no Lease Event of Default is continuing, the Owner
  Trustee shall direct the Indenture Trustee to execute and deliver to the
  Owner Trustee an appropriate instrument releasing such Airframe and/or
  Engine as appropriate from the Lien of this Trust Indenture and the
  Indenture Trustee shall execute and deliver such instrument as aforesaid,
  but only upon compliance by Lessee with the applicable provisions of
  Section 10 of the Lease and upon receipt by the Indenture Trustee of a
  written request from the Owner Trustee, requesting such release and
  specifically describing the Airframe and/or Engine(s) so to be released.

            SECTION 5.07.   Indenture Supplements for Replacements.

            If a Replacement Airframe or Replacement Engine is being
  substituted as contemplated by Section 10 of the Lease, the Owner Trustee
  and the Indenture Trustee agree for the benefit of the Note Holders and
  Lessee, subject to fulfillment of the conditions precedent and compliance
  by Lessee with its obligations set forth in Section 10 of the Lease and
  the requirements of Section 5.06 hereof with respect to such Replacement
  Airframe or Replacement Engine, to execute and deliver a Lease Supplement
  and a Trust Agreement and Indenture Supplement, as applicable, as
  contemplated by Section 10 of the Lease.

            SECTION 5.08.   Effect of Replacement.

            In the event of the substitution of an Airframe or of a
  Replacement Engine pursuant to Section 10 of the Lease, (a) all
  provisions of this Trust Indenture relating to the Airframe or Engine or
  Engines being replaced shall be applicable to such Replacement Airframe
  or Replacement Engine or Engines with the same force and effect as if
  such Replacement Airframe or Replacement Engine or Engines were the same
  airframe or engine or engines, as the case may be, as the Airframe or
  Engine or Engines being replaced but for the Event of Loss with respect
  to the Airframe or Engine or Engines being replaced, and (b) the
  provisions of this Trust Indenture shall no longer be applicable to the
  Airframe or Engine or Engines being replaced, which shall be released
  from the Lien of this Indenture.

            SECTION 5.09.   Investment of Amounts Held by Indenture
  Trustee.

            Any amounts held by the Indenture Trustee as assignee of the
  Owner Trustee's rights to hold monies for security pursuant to Section 21
  of the Lease shall be held in accordance with the terms of such Section
  and the Indenture Trustee agrees, for the benefit of Lessee, to perform
  the duties of the Owner Trustee under such Section.  Any amounts held by
  the Indenture Trustee pursuant to the proviso to the first sentence of
  Section 3.01, pursuant to Section 3.02, or pursuant to any provision of
  any other Operative Document providing for amounts to be held by the
  Indenture Trustee which are not distributed pursuant to the other
  provisions of Article III hereof shall be invested by the Indenture
  Trustee from time to time in Cash Equivalents as directed by Lessee so
  long as the Indenture Trustee may acquire the same using its best
  efforts.  Unless otherwise expressly provided in this Trust Indenture,
  any income realized as a result of any such investment, net of the
  Indenture Trustee's reasonable fees and expenses in making such
  investment, shall be held and applied by the Indenture Trustee in the
  same manner as the principal amount of such investment is to be applied
  and any losses, net of earnings and such reasonable fees and expenses,
  shall be charged against the principal amount invested.  The Indenture
  Trustee shall not be liable for any loss resulting from any investment
  required to be made by it under this Trust Indenture other than by reason
  of its willful misconduct or gross negligence, and any such investment
  may be sold (without regard to its maturity) by the Indenture Trustee
  without instructions whenever such sale is necessary to make a
  distribution required by this Trust Indenture.

                                 ARTICLE VI

                THE OWNER TRUSTEE AND THE INDENTURE TRUSTEE

            SECTION 6.01.   Acceptance of Trusts and Duties.

            The Indenture Trustee accepts the duties hereby created and
  applicable to it and agrees to perform the same but only upon the terms
  of this Trust Indenture and agrees to receive and disburse all monies
  constituting part of the Trust Indenture Estate in accordance with the
  terms hereof.  The Owner Trustee, in its individual capacity, and the
  Indenture Trustee, in its individual capacity, shall not be answerable or
  accountable under any circumstances, except (i) for their own willful
  misconduct or gross negligence (other than for the handling of funds, for
  which the standard of accountability shall be willful misconduct or
  negligence), (ii) in the case of the Indenture Trustee, as provided in
  the fourth sentence of Section 2.04(a) hereof and the last sentence of
  Section 5.04 hereof, and (iii) for liabilities that may result, in the
  case of the Owner Trustee, from the inaccuracy of any representation or
  warranty of the Owner Trustee expressly made in its individual capacity
  in the Participation Agreement or in Section 6.03 hereof (or in any
  certificate furnished to the Indenture Trustee or any Note Holder in
  connection with the transactions contemplated by the Operative Documents)
  or, in the case of the Indenture Trustee (in its individual capacity),
  from the inaccuracy of any representation or warranty of the Indenture
  Trustee (in its individual capacity) in the Participation Agreement or
  expressly made hereunder.  Neither the Owner Trustee nor the Indenture
  Trustee shall be liable for any action or inaction of the other or of the
  Owner Participant.

            SECTION 6.02.   Absence of Duties.

            In the case of the Indenture Trustee, except in accordance with
  written instructions furnished pursuant to Section 5.01 or 5.02 hereof,
  and except as provided in, and without limiting the generality of,
  Sections 5.03 and 5.04 hereof and, in the case of the Owner Trustee, the
  Owner Trustee and the Indenture Trustee shall have no duty (i) to see to
  any registration of the Aircraft or any recording or filing of the Lease
  or of this Trust Indenture or any other document, or to see to the
  maintenance of any such registration, recording or filing, (ii) to see to
  any insurance on the Aircraft or to effect or maintain any such
  insurance, whether or not Lessee shall be in default with respect
  thereto, (iii) to see to the payment or discharge of any lien or
  encumbrance of any kind against any part of the Trust Estate or the Trust
  Indenture Estate, (iv) to confirm, verify or inquire into the failure to
  receive any financial statements from Lessee, or (v) to inspect the
  Aircraft at any time or ascertain or inquire as to the performance or
  observance of any of Lessee's covenants under the Lease with respect to
  the Aircraft.  The Owner Participant shall not have any duty or
  responsibility hereunder, including, without limitation, any of the
  duties mentioned in clauses (i) through (v) above; provided, that nothing
  contained in this sentence shall limit any obligations of the Owner
  Participant under the Participation Agreement or relieve the Owner
  Participant from any restriction under Section 4.03 hereof.

            SECTION 6.03.   No Representations or Warranties as to Aircraft
  or Documents.

            NEITHER THE INDENTURE TRUSTEE IN ITS INDIVIDUAL OR TRUST
  CAPACITY NOR THE OWNER TRUSTEE IN ITS INDIVIDUAL CAPACITY OR AS OWNER
  TRUSTEE UNDER THE TRUST AGREEMENT, NOR THE OWNER PARTICIPANT MAKES OR
  SHALL BE DEEMED TO HAVE MADE AND EACH HEREBY EXPRESSLY DISCLAIMS ANY
  REPRESENTATION OR WARRANTY, EXPRESS OR IMPLIED, AS TO THE TITLE,
  AIRWORTHINESS, VALUE, COMPLIANCE WITH SPECIFICATIONS, CONDITION, DESIGN,
  QUALITY, DURABILITY, OPERATION, MERCHANTABILITY OR FITNESS FOR USE FOR A
  PARTICULAR PURPOSE OF THE AIRCRAFT OR ANY ENGINE, AS TO THE ABSENCE OF
  LATENT OR OTHER DEFECTS, WHETHER OR NOT DISCOVERABLE, AS TO THE ABSENCE
  OF ANY INFRINGEMENT OF ANY PATENT, TRADEMARK OR COPYRIGHT, AS TO THE
  ABSENCE OF OBLIGATIONS BASED ON STRICT LIABILITY IN TORT OR ANY OTHER
  REPRESENTATION OR WARRANTY WHATSOEVER, except the Owner Trustee in its
  individual capacity warrants that (i) the Owner Trustee has received on
  the Delivery Date whatever title was conveyed to it by Lessee, and (ii)
  the Aircraft is free and clear of Lessor Liens attributable to the Owner
  Trustee in its individual capacity.  Neither the Owner Trustee, in its
  individual capacity or as Owner Trustee under the Trust Agreement, nor
  the Indenture Trustee, in its individual or trust capacities, makes or
  shall be deemed to have made any representation or warranty as to the
  validity, legality or enforceability of this Trust Indenture, the Trust
  Agreement, the Participation Agreement, the Equipment Notes, the Lease,
  the Purchase Agreement, the Purchase Agreement Assignment, or the Consent
  and Agreement, or as to the correctness of any statement contained in any
  thereof, except for the representations and warranties of the Owner
  Trustee made in its individual capacity and the representations and
  warranties of the Indenture Trustee, in each case expressly made in this
  Trust Indenture or in the Participation Agreement.  The Loan
  Participants, the Note Holders and the Owner Participant make no
  representation or warranty hereunder whatsoever.

            SECTION 6.04.   No Segregation of Monies; No Interest.

            Any monies paid to or retained by the Indenture Trustee
  pursuant to any provision hereof and not then required to be distributed
  to the Note Holders, Lessee or the Owner Trustee as provided in Article
  III hereof need not be segregated in any manner except to the extent
  required by Law or as specifically provided in the Lease and Section 5.09
  hereof, and may be deposited under such general conditions as may be
  prescribed by Law, and the Indenture Trustee shall not be liable for any
  interest thereon (except that the Indenture Trustee shall invest all
  monies held as directed by Lessee so long as no Lease Event of Default
  has occurred and is continuing (or in the absence of such direction, by
  the Majority In Interest of Note Holders)) in Cash Equivalents; provided,
  however, that any payments received, or applied hereunder, by the
  Indenture Trustee shall be accounted for by the Indenture Trustee so that
  any portion thereof paid or applied pursuant hereto shall be identifiable
  as to the source thereof.

            SECTION 6.05.   Reliance; Agreements; Advice of Counsel.

            Neither the Owner Trustee nor the Indenture Trustee shall incur
  any liability to anyone in acting upon any signature, instrument, notice,
  resolution, request, consent, order, certificate, report, opinion, bond
  or other document or paper believed by it to be genuine and believed by
  it to be signed by the proper party or parties.  The Owner Trustee and
  the Indenture Trustee may accept a copy of a resolution of the Board of
  Directors (or, in the case of the Owner Participant which originally
  executed the Participation Agreement, evidence of the approval by the
  Executive Committee thereof) of any party to the Participation Agreement,
  certified by the Secretary or an Assistant Secretary thereof as duly
  adopted and in full force and effect, as conclusive evidence that such
  resolution has been duly adopted and that the same is in full force and
  effect.  As to the aggregate unpaid Principal Amount of Equipment Notes
  outstanding as of any date, the Owner Trustee may for all purposes hereof
  rely on a certificate signed by any Vice President or other authorized
  corporate trust officer of the Indenture Trustee.  As to any fact or
  matter relating to Lessee the manner of ascertainment of which is not
  specifically described herein, the Owner Trustee and the Indenture
  Trustee may for all purposes hereof rely on a certificate, signed by a
  duly authorized officer of Lessee, as to such fact or matter, and such
  certificate shall constitute full protection to the Owner Trustee and the
  Indenture Trustee for any action taken or omitted to be taken by them in
  good faith in reliance thereon.  The Indenture Trustee shall assume, and
  shall be fully protected in assuming, that the Owner Trustee is
  authorized by the Trust Agreement to enter into this Trust Indenture and
  to take all action to be taken by it pursuant to the provisions hereof,
  and shall not inquire into the authorization of the Owner Trustee with
  respect thereto.  In the administration of the trusts hereunder, the
  Owner Trustee and the Indenture Trustee each may execute any of the
  trusts or powers hereof and perform its powers and duties hereunder
  directly or through agents or attorneys and may at the expense of the
  Trust Indenture Estate, consult with counsel, accountants and other
  skilled persons to be selected and retained by it, and the Owner Trustee
  and the Indenture Trustee shall not be liable for anything done, suffered
  or omitted in good faith by them in accordance with the advice or opinion
  of any such counsel, accountants or other skilled persons.

            SECTION 6.06.   Capacity in Which Acting.

            The Owner Trustee acts hereunder solely as trustee as herein
  and in the Trust Agreement provided, and not in its individual capacity,
  except as otherwise expressly provided herein, in the Trust Agreement and
  in the Participation Agreement.

            SECTION 6.07.   Compensation.

            The Indenture Trustee shall be entitled to reasonable
  compensation, including expenses and disbursements (including the
  reasonable fees and expenses of counsel), for all services rendered
  hereunder and shall, on and subsequent to an Event of Default hereunder,
  have a priority claim on the Trust Indenture Estate for the payment of
  such compensation, to the extent that such compensation shall not be paid
  by Lessee, and shall have the right, on and subsequent to an Event of
  Default hereunder, to use or apply any monies held by it hereunder in the
  Trust Indenture Estate toward such payments.  The Indenture Trustee
  agrees that it shall have no right against the Loan Participants, the
  Note Holders, the Owner Trustee or the Owner Participant for any fee as
  compensation for its services as trustee under this Trust Indenture.

            SECTION 6.08.   Instructions from Note Holders.

            In the administration of the trusts created hereunder, the
  Indenture Trustee shall have the right to seek instructions from a
  Majority in Interest of Note Holders should any provision of this Trust
  Indenture appear to conflict with any other provision herein or should
  the Indenture Trustee's duties or obligations hereunder be unclear, and
  the Indenture Trustee shall incur no liability in refraining from acting
  until it receives such instructions.  The Indenture Trustee shall be
  fully protected for acting
  in accordance with any instructions received under this Section 6.08.

                                ARTICLE VII

           INDEMNIFICATION OF INDENTURE TRUSTEE BY OWNER TRUSTEE

            SECTION 7.01.   Scope of Indemnification.

            The Owner Trustee, not in its individual capacity, but solely
  as Owner Trustee, hereby agrees, except as otherwise provided in Section
  2.03 or 2.04(b) hereof, to assume liability for, and does hereby
  indemnify, protect, save and keep harmless the Indenture Trustee (in its
  individual and trust capacities), and its successors, assigns, agents and
  servants, from and against any and all liabilities, obligations, losses,
  damages, penalties, taxes (excluding any taxes payable by the Indenture
  Trustee on or measured by any compensation received by the Indenture
  Trustee for its services under this Trust Indenture), claims, actions,
  suits, costs, expenses or disbursements (including reasonable legal fees
  and expenses) of any kind and nature whatsoever, which may be imposed on,
  incurred by or asserted against the Indenture Trustee (whether or not
  also indemnified against by any other Person under any other document) in
  any way relating to or arising out of this Trust Indenture or any other
  Operative Document to which it is a party or the enforcement of any of
  the terms of any thereof, or in any way relating to or arising out of the
  manufacture, purchase, acceptance, non-acceptance, rejection, ownership,
  delivery, lease, possession, use, operation, condition, sale, return or
  other disposition of the Aircraft or any Engine (including, without
  limitation, latent or other defects, whether or not discoverable, and any
  claim for patent, trademark or copyright infringement), or in any way
  relating to or arising out of the administration of the Trust Indenture
  Estate or the action or inaction of the Indenture Trustee hereunder, to
  the extent not reimbursed by Lessee.  Notwithstanding any provision to
  the contrary herein, the scope of the Owner Trustee's indemnity
  obligations under this Section 7.01 shall not exceed the scope of the
  indemnity obligations of Lessee under the Participation Agreement and the
  Lease; and the Indenture Trustee agrees that, prior to seeking
  indemnification from the Trust Indenture Estate, it will demand, and take
  such action as it may determine to be reasonable to pursue,
  indemnification available to the Indenture Trustee under the Lease or the
  Participation Agreement.  Notwithstanding the foregoing, the Indenture
  Trustee shall not be entitled to any indemnification for any Expenses to
  the extent relating to or arising from the willful misconduct or gross
  negligence (or negligence in the case of handling funds) of the Indenture
  Trustee in the performance of its duties hereunder or resulting from the
  inaccuracy of any representation or warranty of the Indenture Trustee (in
  its individual capacity) referred to in Section 6.03 hereof, or as
  provided in Section 6.01 hereof or in the last sentence of Section 5.04
  hereof, or as otherwise excluded by the terms of Sections 6(b) and 6(c)
  of the Participation Agreement from Lessee's indemnities under such
  Sections.  In addition, if necessary, the Indenture Trustee shall be
  entitled to indemnification from the Trust Indenture Estate for any
  liability, obligation, loss, damage, penalty, claim, action, suit, cost,
  expense or disbursement indemnified against pursuant to this Section 7.01
  to the extent not reimbursed by Lessee or others, but without releasing
  any of them from their respective agreements of reimbursement; and to
  secure the same the Indenture Trustee shall have a prior Lien on the
  Trust Indenture Estate.  The Owner Trustee shall be subrogated to the
  Indenture Trustee's rights, if any, to payment from Lessee for amounts
  paid by the Owner Trustee under this Section 7.01.

                                ARTICLE VIII

                      SUCCESSOR AND SEPARATE TRUSTEES

            SECTION 8.01.   Notice of Successor Owner Trustee.

            In the case of any appointment of a successor to the Owner
  Trustee pursuant to the Trust Agreement including upon any merger,
  conversion, consolidation or sale of substantially all of the corporate
  trust business of the Owner Trustee pursuant to the Trust Agreement, the
  successor Owner Trustee shall give prompt written notice thereof to the
  Indenture Trustee, Lessee and the Note Holders.

            SECTION 8.02.   Resignation of Indenture Trustee; Appointment
  of Successor.

            (a)  The Indenture Trustee or any successor thereto may resign
  at any time without cause by giving at least thirty (30) days prior
  written notice to Lessee, the Owner Trustee, the Owner Participant and
  each Note Holder, such resignation to be effective upon the acceptance of
  the trusteeship by a successor Indenture Trustee.  In addition, a
  Majority in Interest of Note Holders may at any time (but only with the
  consent of Lessee, which consent shall not be unreasonably withheld,
  except that such consent shall not be necessary if a Lease Event of
  Default shall have occurred and be continuing) remove the Indenture
  Trustee without cause by an instrument in writing delivered to the Owner
  Trustee, Lessee, the Owner Participant and the Indenture Trustee, and the
  Indenture Trustee shall promptly notify each Note Holder thereof in
  writing, such removal to be effective upon the acceptance of the
  trusteeship by a successor Indenture Trustee.  In the case of the
  resignation or removal of the Indenture Trustee, a Majority in Interest
  of Note Holders may appoint a successor Indenture Trustee by an
  instrument signed by such holders, which successor, so long as no Lease
  Event of Default shall have occurred and be continuing, shall be subject
  to Lessee's reasonable approval.  If a successor Indenture Trustee shall
  not have been appointed within thirty (30) days after such notice of
  resignation or removal, the Indenture Trustee, the Owner Trustee, the
  Owner Participant or any Note Holder may apply to any court of competent
  jurisdiction to appoint a successor Indenture Trustee to act until such
  time, if any, as a successor shall have been appointed as above provided.
  The successor Indenture Trustee so appointed by such court shall
  immediately and without further act be superseded by any successor
  Indenture Trustee appointed as above provided.

            (b)  Any successor Indenture Trustee, however appointed, shall
  execute and deliver to the Owner Trustee, the predecessor Indenture
  Trustee and Lessee an instrument accepting such appointment and assuming
  the obligations of the Indenture Trustee under the Participation
  Agreement arising from and after the time of such appointment, and
  thereupon such successor Indenture Trustee, without further act, shall
  become vested with all the estates, properties, rights, powers and duties
  of the predecessor Indenture Trustee hereunder in the trust hereunder
  applicable to it with like effect as if originally named the Indenture
  Trustee herein; but nevertheless upon the written request of such
  successor Indenture Trustee, such predecessor Indenture Trustee shall
  execute and deliver an instrument transferring to such successor
  Indenture Trustee, upon the trusts herein expressed applicable to it, all
  the estates, properties, rights and powers of such predecessor Indenture
  Trustee, and such predecessor Indenture Trustee shall duly assign,
  transfer, deliver and pay over to such successor Indenture Trustee all
  monies or other property then held by such predecessor Indenture Trustee
  hereunder.

            (c)  Any successor Indenture Trustee, however appointed, shall
  be a bank or trust company having its principal place of business in the
  United States and having (or whose obligations under the Operative
  Documents are guaranteed by an affiliated entity having) a combined
  capital and surplus of at least $100,000,000, if there be such an
  institution willing, able and legally qualified to perform the duties of
  the Indenture Trustee hereunder upon reasonable or customary terms.

            (d)  Any corporation into which the Indenture 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 Indenture Trustee shall be a party, or any corporation to which
  substantially all the corporate trust business of the Indenture Trustee
  may be transferred, shall, subject to the terms of paragraph (c) of this
  Section 8.02, be a successor Indenture Trustee and the Indenture Trustee
  under this Trust Indenture without further act.

            SECTION 8.03.   Appointment of Additional and Separate
  Trustees.

            (a)  Whenever (i) the Indenture Trustee shall deem it necessary
  or desirable in order to conform to any law of any jurisdiction in which
  all or any part of the Trust Indenture Estate shall be situated or to
  make any claim or bring any suit with respect to or in connection with
  the Trust Indenture Estate, this Trust Indenture, any other Indenture
  Agreement, the Equipment Notes or any of the transactions contemplated by
  the Participation Agreement, (ii) the Indenture Trustee shall be advised
  by counsel satisfactory to it that it is so necessary or prudent in the
  interests of the Note Holders (and the Indenture Trustee shall so advise
  the Owner Trustee and Lessee), or (iii) the Indenture Trustee shall have
  been requested to do so by a Majority in Interest of Note Holders, then
  in any such case, the Indenture Trustee and, upon the written request of
  the Indenture Trustee, the Owner Trustee, shall execute and deliver an
  indenture supplemental hereto and such other instruments as may from time
  to time be necessary or advisable either (1) to constitute one or more
  bank or trust companies or one or more Persons approved by the Indenture
  Trustee, either to act jointly with the Indenture Trustee as additional
  trustee or trustees of all or any part of the Trust Indenture Estate, or
  to act as separate trustee or trustees of all or any part of the Trust
  Indenture Estate, in each case with such rights, powers, duties and
  obligations consistent with this Trust Indenture as may be provided in
  such supplemental indenture or other instruments as the Indenture Trustee
  or a Majority in Interest of Note Holders may deem necessary or
  advisable, or (2) to clarify, add to or subtract from the rights, powers,
  duties and obligations theretofore granted any such additional and
  separate trustee, subject in each case to the remaining provisions of
  this Section 8.03.  If the Owner Trustee shall not have taken any action
  requested of it under this Section 8.03(a) that is permitted or required
  by its terms within 15 days after the receipt of a written request from
  the Indenture Trustee so to do, or if an Event of Default shall have
  occurred and be continuing, the Indenture Trustee may act under the
  foregoing provisions of this Section 8.03(a) without the concurrence of
  the Owner Trustee; and the Owner Trustee hereby irrevocably appoints
  (which appointment is coupled with an interest) the Indenture Trustee,
  its agent and attorney-in-fact to act for it under the foregoing
  provisions of this Section 8.03(a) in either of such contingencies.  The
  Indenture Trustee may, in such capacity, execute, deliver and perform any
  such supplemental indenture, or any such instrument, as may be required
  for the appointment of any such additional or separate trustee or for the
  clarification of, addition to or subtraction from the rights, powers,
  duties or obligations theretofore granted to any such additional or
  separate trustee. In case any additional or separate trustee appointed
  under this Section 8.03(a) shall die, become incapable of acting, resign
  or be removed, all the assets, property, rights, powers, trusts, duties
  and obligations of such additional or separate trustee shall revert to
  the Indenture Trustee until a successor additional or separate trustee is
  appointed as provided in this Section 8.03(a).

            (b)  No additional or separate trustee shall be entitled to
  exercise any of the rights, powers, duties and obligations conferred upon
  the Indenture Trustee in respect of the custody, investment and payment
  of monies and all monies received by any such additional or separate
  trustee from or constituting part of the Trust Indenture Estate or
  otherwise payable under any Operative Document to the Indenture Trustee
  shall be promptly paid over by it to the Indenture Trustee.  All other
  rights, powers, duties and obligations conferred or imposed upon any
  additional or separate trustee shall be exercised or performed by the
  Indenture Trustee and such additional or separate trustee jointly except
  to the extent that applicable law of any jurisdiction in which any
  particular act is to be performed renders the Indenture Trustee
  incompetent or unqualified to perform such act, in which event such
  rights, powers, duties and obligations (including the holding of title to
  all or part of the Trust Indenture Estate in any such jurisdiction) shall
  be exercised and performed by such additional or separate trustee.  No
  additional or separate trustee shall take any discretionary action except
  on the instructions of the Indenture Trustee or a Majority in Interest of
  Note Holders.  No trustee hereunder shall be personally liable by reason
  of any act or omission of any other trustee hereunder, except that the
  Indenture Trustee shall be liable for the consequences of its lack of
  reasonable care in selecting, and Indenture Trustee's own actions in
  acting with, any additional or separate trustee.  Each additional or
  separate trustee appointed pursuant to this Section 8.03 shall be subject
  to, and shall have the benefit of Articles IV through VIII and Article X
  hereof insofar as they apply to the Indenture Trustee.  The powers of any
  additional or separate trustee appointed pursuant to this Section 8.03
  shall not in any case exceed those of the Indenture Trustee hereunder.

            (c)  If at any time the Indenture Trustee shall deem it no
  longer necessary or desirable in order to conform to any such law or take
  any such action or shall be advised by such counsel that it is no longer
  so necessary or desirable in the interest of the Note Holders, or in the
  event that the Indenture Trustee shall have been requested to do so in
  writing by a Majority in Interest of Note Holders, the Indenture Trustee
  and, upon the written request of the Indenture Trustee, the Owner
  Trustee, shall execute and deliver an indenture supplemental hereto and
  all other instruments and agreements necessary or proper to remove any
  additional or separate trustee.  The Indenture Trustee may act on behalf
  of the Owner Trustee under this Section 8.03(c) when and to the extent it
  could so act under Section 8.03(a) hereof.

                                 ARTICLE IX

             SUPPLEMENTS AND AMENDMENTS TO THIS TRUST INDENTURE
                            AND OTHER DOCUMENTS

            SECTION 9.01.   Instructions of Majority; Limitations.

            (a)  Except as expressly provided in Section 5.02 hereof, and
  except with respect to Excluded Payments, the Owner Trustee agrees it
  shall not enter into any amendment of or supplement to the Lease, the
  Purchase Agreement (to the extent assigned in the Purchase Agreement
  Assignment), the Purchase Agreement Assignment, the Consent and
  Agreement, or execute and deliver any written waiver or modification of,
  or consent under, the terms of the Lease, the Purchase Agreement (to the
  extent assigned in the Purchase Agreement Assignment), the Purchase
  Agreement Assignment, the Consent and Agreement, unless such supplement,
  amendment, waiver, modification or consent is consented to in writing by
  the Indenture Trustee and a Majority in Interest of Note Holders.
  Anything to the contrary contained herein notwithstanding, without the
  necessity of the consent of any of the Note Holders or the Indenture
  Trustee, (i) any Excluded Payments payable to the Owner Participant may
  be modified, amended, changed or waived in such manner as shall be agreed
  to by the Owner Participant and Lessee and (ii) the Owner Trustee and
  Lessee may enter into amendments of or additions to the Lease to modify
  Section 5 (except to the extent that such amendment would affect the
  rights or exercise of remedies under Section 15 of the Lease), Section 9,
  Section 19 or Section 20 of the Lease so long as such amendments,
  modifications and changes do not and would not affect the time of, or
  reduce the amount of, Rent payments (except to the extent expressly
  permitted by Section 5.02) until after the payment in full of all Secured
  Obligations or otherwise adversely affect the Note Holders.

            (b)  Without limiting the provisions of Section 9.01(a) hereof
  and subject to Section 5.02(a)(2)(i) hereof, the Indenture Trustee agrees
  with the Note Holders that it shall not enter into any amendment, waiver
  or modification of, supplement or consent to this Trust Indenture, the
  Lease, the Purchase Agreement, the Purchase Agreement Assignment, the
  Consent and Agreement or the Participation Agreement, or any other
  agreement included in the Trust Indenture Estate, unless such supplement,
  amendment, waiver, modification or consent is consented to in writing by
  a Majority in Interest of Note Holders, or does not adversely affect the
  Note Holders, but upon the written request of a Majority in Interest of
  Note Holders, the Indenture Trustee shall from time to time enter into
  any such supplement or amendment, or execute and deliver any such waiver,
  modification or consent, as may be specified in such request and as may
  be (in the case of any such amendment, supplement or modification), to
  the extent such agreement is required, agreed to by the Owner Trustee and
  Lessee or, as may be appropriate, the Manufacturer; provided, however,
  that, without the consent of each holder of an affected Equipment Note
  then outstanding, each Liquidity Provider and the Policy Provider, no
  such amendment of or supplement to this Trust Indenture, the Lease, the
  Purchase Agreement, the Purchase Agreement Assignment, the Consent and
  Agreement or the Participation Agreement or waiver or modification of the
  terms of, or consent under, any thereof, shall (i) modify any of the
  provisions of this Section 9.01, or of Sections 2.02, 2.10, 2.11, 2.15,
  4.02, 4.04(c), 4.04(d), 5.02 or 5.06 hereof, Section 14 (except to add an
  Event of Default) of the Lease, the definitions of "Event of Default",
  "Default", "Lease Event of Default", "Lease Default", "Majority in
  Interest of Note Holders", "Make-Whole Amount" or "Note Holder", or the
  percentage of Note Holders required to take or approve any action
  hereunder, (ii) reduce the amount, or change the time of payment or
  method of calculation of any amount, of Principal Amount, Make-Whole
  Amount, if any, or interest with respect to any Equipment Note, or alter
  or modify the provisions of Article III hereof with respect to the order
  of priorities in which distribution thereunder shall be made as among the
  Note Holders, the Owner Trustee and Lessee, (iii) reduce, modify or amend
  any indemnities in favor of the Note Holders, (iv) consent to any change
  in the Trust Indenture or the Lease which would permit redemption of
  Equipment Notes earlier than permitted under Section 2.10 or 2.11 hereof

      reserved below, including, without limitation, in such assignment to

 Lessor, to exercise in the Lessee's name all rights and powers related to
 the Assigned Rights and to retain any recovery or benefit resulting from
 the enforcement of any of the Assigned Rights in respect of the Aircraft,
 except that the Lessee may not enter into any change order or other
 amendment, modification or supplement to the Purchase Agreement without the

 Assignment, AVSA shall not be deemed to have knowledge of and need not
 recognize any Event of Default, unless and until AVSA shall have received
 written notice thereof from the Lessor or the Indenture Trustee addressed
 to its Chief Executive Officer, 2, Rond Point Maurice Bellonte, 31700
 Blagnac, France (telex 521155F) (fax:  011-33-5-6130-4011) and, in acting
 in accordance with the terms of the Purchase Agreement and this Assignment,
 AVSA may act with acquittance and conclusively rely upon any such notice.

 3.   Certain Rights and Obligations of the Parties.  (a) Assignor Remains
      Liable.  It is expressly agreed that, anything herein contained to the
      contrary notwithstanding:  (a) the Assignor shall at all times remain
      liable to AVSA under the Purchase Agreement to perform all the duties
      and obligations of the "Buyer" thereunder to the same extent as if
      this Assignment had not been executed; (b) the exercise by the Lessor
      of any of the rights assigned hereunder shall not release the Assignor
      from any of its duties or obligations to AVSA under the Purchase
      Agreement except to the extent that such exercise by the Lessor shall
      constitute performance of such duties and obligations; and (c) except
      as provided in the next succeeding paragraph, none of the Lessor, the
      Indenture Trustee nor any Participant shall have any obligation or
      liability under the Purchase Agreement by reason of, or arising out
      of, this Assignment or be obligated to perform any of the obligations
      or duties of the Assignor under the Purchase Agreement or to make any
      payment or to make any inquiry as to the sufficiency of any payment
      received by any of them or to present or file any claim or to take any
      other action to collect or enforce any claim for any payment assigned
      hereunder.

           (b) Lessor Bound by Purchase Agreement.  Without in any way
 releasing the Assignor from any of its duties or obligations under the
 Purchase Agreement, the Lessor confirms for the benefit of AVSA that,
 insofar as the provisions of the Purchase Agreement relate to the Aircraft,
 in exercising any rights under the Purchase Agreement, or in making any
 claim with respect to the Aircraft or other goods and services delivered or
 to be delivered pursuant to the Purchase Agreement, the terms and
 conditions of the Purchase Agreement disclosed to the Lessor in writing
 shall apply to, and be binding upon, the Lessor to the extent of its
 respective interests assigned hereunder to the same extent as the Assignor.

           (c) Limit of Effect of this Assignment.  Nothing contained
 herein shall (i) subject AVSA or the Guarantor to any liability to which it
 would not otherwise be subject under the Purchase Agreement or (ii) modify
 in any respect the contractual rights of AVSA or the Guarantor thereunder
 (except, in each case, as provided in the attached Consents and
 Agreements).

           (d)  Appointment as Attorney-in-Fact.  The Assignor does hereby
 constitute, effective at any time after an Event of Default shall have
 occurred and be continuing, the Lessor and its successors and permitted
 assigns to be the Assignor's true and lawful attorney, irrevocably, with
 full power (in the name of the Assignor or otherwise) to ask, require,
 demand, receive, compound and give acquittance for any and all monies and
 claims for monies due and to become due under, or arising out of, the
 Purchase Agreement and the Consent and Guaranty in respect of the Aircraft,
 to the extent that the same have been assigned as provided in this
 Assignment and, for such period as the Lessor, its successors and assigns
 may exercise rights with respect thereto under this Assignment, to endorse
 any checks or other instruments or orders in connection therewith and to
 file any claims or take any action or institute (or, if previously
 commenced, assume control of) any proceedings and to obtain any recovery in
 connection therewith which the Lessor, its successors and assigns, may deem
 to be necessary or advisable in the premises.

 4.   Further Assurances.  The Assignor and the Lessor each agree that, at
      any time and from time to time, upon the written request of any other
      party hereto, it will promptly and duly execute and deliver any and
      all such further instruments and documents and take such further
      action as the other may reasonably request in order to obtain the full
      benefits of this Assignment and of the rights and powers herein
      granted.

 5.   No Amendment of Purchase Agreement.  So long as the Lease is in
      effect, the Lessor agrees that it shall not enter into any agreement
      that would amend, modify, supplement, rescind, cancel or terminate the
      Purchase Agreement or the Consent and Guaranty in any respect or in
      any way limit the rights of the Assignor or any of the other rights
      assigned hereunder (except as set forth above when there has been an
      Event of Default), without the prior written consent of the Assignor.

 6.   Execution of Assignment.  This Assignment is executed by the Assignor
      and the Lessor concurrently with the execution and delivery of the
      Participation Agreement and the Lease.

 7.   Confidentiality.  The Lessor agrees that it will not disclose to any
      third party the terms of the Purchase Agreement or this Assignment,
      except (a) as required by applicable law or governmental regulation,
      (b) as contemplated in the Lease or the Participation Agreement
      (including as set forth in Section 7(o) of the Participation
      Agreement) or (c) with the consent of the Assignor, the Guarantor and
      AVSA.

 8.   Assignment as Collateral.  Each party hereto consents to the
      assignment and pledge by the Lessor to the Indenture Trustee, as
      security for the Equipment Notes to be issued under the Indenture and
      the other obligations secured thereby as specified in the Indenture,
      of all of the Lessor's right, title and interest in and to the
      Assigned Rights and the Consent and Guaranty under this Assignment
      which assignment shall be on terms identical to this Assignment.

 9.   Counterparts.  This Assignment 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.

 10.  GOVERNING LAW.  THIS ASSIGNMENT SHALL IN ALL RESPECTS BE GOVERNED BY,
      AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK,
      INCLUDING ALL MATTERS OF CONSTRUCTION, VALIDITY AND PERFORMANCE.

 11.  Successors and Assigns.  This Assignment shall be binding upon and
      shall inure to the benefit of the parties hereto and their respective
      successors and permitted assigns.

 12.  Notices.  All notices with respect to the matters contained herein
      shall be delivered (notices with respect to AVSA shall be sent to the
      address for AVSA set forth in Clause 2(e) hereof) in the manner
      provided in Section 12(a) of the Participation Agreement.

 13.  No Oral Amendments.  Neither this Assignment nor any of the terms
      hereof may be terminated, amended, supplemented, waived or modified
      orally, but only by an instrument in writing signed by the party
      against whom the enforcement of such termination, amendment,
      supplement, waiver or modification is sought.


                          *     *     *     *    *

           SECTION 5.01   NOTICE OF EVENT OF DEFAULT. If the Owner Trustee
 shall have knowledge of a Lease Event of Default or an Indenture Event of
 Default (or a Lease Default or an event which with the passage of time or

 telephonic or telecopy notice thereof followed by prompt confirmation
 thereof by certified mail, postage prepaid, provided that (i) in the case
 of an event which, with the passage of time would constitute an Indenture

 Indenture, such notice shall in no event be furnished later within ten (10)
 days after the Owner Trustee shall first have knowledge of such event and
 (ii) in the case of a misrepresentation by the Owner Trustee which with the
 passage of time would constitute an Indenture Event of Default referred to

 shall first have knowledge of such event. Subject to the terms of Section

 taking such action, not inconsistent with the provisions of the Trust
 Indenture, with respect to such Lease Event of Default, Indenture Event of
 Default or other event as the Owner Trustee shall be directed in writing by
 the Owner Participant. If the Owner Trustee shall not have received
 instructions as above provided within twenty (20) days after the mailing of
 such notice to the Owner Participant, the Owner Trustee until instructed
 otherwise in accordance with the preceding sentence may, but shall be under
 no duty to, take or refrain from taking such action with respect to such
 Lease Event of Default, Indenture Event of Default or other event, not
 inconsistent with the provisions of the Trust Indenture, as it shall deem

 of this Trust Agreement, the Lease and the other Operative Documents, in
 the absence of actual knowledge by an officer of FSB in the Corporate Trust
 Department, the Owner Trustee shall not be deemed to have knowledge of a
 Lease Event of Default, an Indenture Event of Default or other event
 referred to in this Section 5.01 unless notified in writing by the
 Indenture Trustee, the Owner Participant or Lessee.

           SECTION 5.02   ACTION UPON INSTRUCTIONS. Subject to the terms of
 Sections 5.01 and 5.03 hereof, upon the written instructions at any time
 and from time to time of the Owner Participant, the Owner Trustee will take
 such of the following actions, not inconsistent with the provisions of the
 Trust Indenture, as may be specified in such instructions: (i) give such
 notice or direction or exercise such right, remedy or power hereunder or
 under any of the Operative Documents to which the Owner Trustee is a party

 clause (i) of Section 8.01 hereof and in clause (U) of Section 7(k) of the
 Participation Agreement); (ii) take such action to preserve or protect the
 Trust Estate (including the discharge of Liens) as may be specified in such
 instructions; (iii) approve as satisfactory to it all matters required by
 the terms of the Lease or the other Operative Documents to be satisfactory
 to the Owner Trustee, it being understood that without written instructions
 of the Owner Participant, the Owner Trustee shall not approve any such
 matter as satisfactory to it (it being understood that the provisions of
 Sections 3.03, 3.04 and 3.06 hereof do not constitute instructions by the
 Owner Participant for the Owner Trustee to approve of or consent to the
 matters to be approved of or consented to by the Owner Trustee in the
 sections of the Lease referred to in Sections 3.03, 3.04 or 3.06 hereof);

 after the expiration or earlier termination of the Lease, deliver the
 Aircraft to the Owner Participant in accordance with such instructions,
 convey all of the Owner Trustee's right, title and interest in and to the

 as shall be designated in such instructions, or net lease the Aircraft on
 such terms and to such lessee or lessees as shall be designated in such
 instructions.

           SECTION 5.03   INDEMNIFICATION. The Owner Trustee shall not be
 required to take any action under Section 5.01 (other than the giving of
 the notices referred to therein) or 5.02 hereof unless the Owner Trustee
 shall have been indemnified by the Owner Participant, in manner and form
 satisfactory to the Owner Trustee, against any liability, cost or expense
 (including reasonable counsel fees and disbursements) which may be incurred
 in connection therewith; and, if the Owner Participant shall have directed
 the Owner Trustee to take any such action or refrain from taking any
 action, the Owner Participant agrees to furnish such indemnity as shall be
 required and, in addition, to the extent not otherwise paid pursuant to the
 provisions of the Lease or the Participation Agreement, to pay the
 reasonable compensation of the Owner Trustee for the services performed or
 to be performed by it pursuant to such direction and any fees and
 disbursements of counsel or agents employed by the Owner Trustee in
 connection therewith. The Owner Trustee shall not be required to take any
 action under Section 5.01 or 5.02 hereof if the Owner Trustee shall
 reasonably determine, or shall have been advised by counsel, that such
 action is contrary to the terms of any of the Operative Documents to which
 the Owner Trustee is a party, or is otherwise contrary to law.

           SECTION 5.04   NO DUTIES EXCEPT AS SPECIFIED IN TRUST AGREEMENT
 OR INSTRUCTIONS. The Owner Trustee shall not have any duty or obligation to
 manage, control, use, sell, dispose of or otherwise deal with the Aircraft
 or any other part of the Trust Estate, or to otherwise take or refrain from
 taking any action under, or in connection with any of the Operative
 Documents to which the Owner Trustee is a party, except as expressly
 required by the terms of any of the Operative Documents to which the Owner
 Trustee is a party, or (to the extent not inconsistent with the provisions
 of the Trust Indenture) as expressly provided by the terms hereof or in
 written instructions from the Owner Participant received pursuant to the
 terms of Section 5.01 or 5.02, and no implied duties or obligations shall
 be read into this Trust Agreement against the Owner Trustee. FSB agrees
 that it will, in its individual capacity and at its own cost or expense
 (but without any right of indemnity in respect of any such cost or expense
 under Section 7.01 hereof) promptly take such action as may be necessary to
 duly discharge and satisfy in full all Lessor Liens which it is required to
 discharge pursuant to Section 7(f) of the Participation Agreement and
 otherwise comply with the terms of said Section binding on it.

           SECTION 5.05   SATISFACTION OF CONDITIONS PRECEDENT. Anything
 herein to the contrary notwithstanding, the Owner Trustee shall comply with
 the provisions of Section 3.01 hereof upon the satisfaction, to the
 satisfaction of special counsel for the Owner Trustee, of all the
 applicable conditions precedent specified in Section 3.02 hereof and in
 Section 4 of the Participation Agreement.

           SECTION 5.06   NO ACTION EXCEPT UNDER SPECIFIED DOCUMENTS OR
 INSTRUCTIONS.  The Owner Trustee shall not have any power, right or
 authority to, and the Owner Trustee agrees that it will not, manage,
 control, use, sell, dispose of or otherwise deal with the Aircraft or any
 other part of the Trust Estate except (i) as expressly required by the
 terms of any of the Operative Documents to which the Owner Trustee is a
 party, (ii) as expressly provided by the terms hereof, or (iii) as
 expressly provided in written instructions from the Owner Participant

 Agreement, or (iv) to inspect Lessee's books and records with respect to
 the Aircraft at any time permitted pursuant to the Lease. Notwithstanding
 the foregoing, the Owner Trustee will furnish to the Indenture Trustee and
 the Owner Participant, promptly upon receipt thereof, duplicates or copies
 of all reports, notices, requests, demands, certificates, financial
 statements and other instruments furnished to the Owner Trustee under the
 Lease or any other Operative Document.

 it, or (b) any representation or warranty as to the validity, legality or
 enforceability of this Trust Agreement or any Operative Document to which

 or the Owner Trustee, as the case may be.

           SECTION 6.04   NO SEGREGATION OF MONIES REQUIRED; NO INTEREST.

 Trustee hereunder need not be segregated in any manner except to the extent

 president, any senior vice president or any vice president or a managing
 director and in the name of the Owner Participant or Lessee, as the case
 may be. The Owner Trustee may accept a copy of a resolution of the Board of
 Directors or Executive Committee of Lessee, certified by the secretary or
 any assistant secretary of Lessee as duly adopted and in full force and
 effect, as conclusive evidence that such resolution has been duly adopted
 by said Board or Committee and that the same is in full force and effect.
 As to any fact or matter the manner of ascertainment of which is not
 specifically described herein, the Owner Trustee may for all purposes
 hereof rely on a certificate signed by a person purporting to be the
 chairman of the board, the president, any executive vice president, any
 senior vice president or any vice president or a managing director of
 Lessee, as to such fact or matter, and such certificate shall constitute
 full protection to the Owner Trustee for any action taken or omitted to be
 taken by it in good faith in reliance thereon. In the administration of
 trusts hereunder, the Owner Trustee may execute any of the trusts or powers
 hereof and perform its powers and duties hereunder directly or through
 agents or attorneys and may, at the expense of the Trust Estate, consult
 with counsel, accountants and other skilled persons to be selected and
 employed by it. The Owner Trustee shall not be liable for anything done,
 suffered or omitted in good faith by it in accordance with the advice or
 opinion of any such counsel, accountants or other skilled persons and the
 Owner Trustee shall not be liable for the negligence of any such agent,
 attorney, counsel, accountant or other skilled person appointed by it with
 due care hereunder.

           SECTION 6.06   NOT ACTING IN INDIVIDUAL CAPACITY. In acting
 hereunder, the Owner Trustee acts solely as trustee and not in its
 individual capacity except as otherwise expressly provided herein; and,
 subject to the terms of the Participation Agreement and the Trust
 Indenture, all persons, other than the Owner Participant, as provided
 herein, having any claim against the Owner Trustee by reason of the
 transactions contemplated hereby shall look only to the Trust Estate for
 payment or satisfaction thereof.

           SECTION 6.07   FEES; COMPENSATION. Except as provided in Section
 5.03 or 7.01 hereof, the Owner Trustee agrees that it shall have no right
 against the Owner Participant or (subject to the provisions of the Trust
 Indenture) the Trust Estate for any fee as compensation for its services
 hereunder.

           SECTION 6.08   TAX RETURNS. The Owner Trustee shall be
 responsible for the keeping of all appropriate books and records relating
 to the receipt and disbursement of all monies under this Trust Agreement or
 any agreement contemplated hereby. The Owner Participant shall be
 responsible for causing to be prepared and filed all income tax returns
 required to be filed by the Owner Participant. The Owner Trustee shall be
 responsible for causing to be prepared, at the request and expense of the
 Owner Participant, all income tax returns required to be filed with respect
 to the trust created hereby and shall execute and file such returns. The
 Owner Participant or the Owner Trustee, as the case may be, upon request,
 will furnish the Owner Trustee or the Owner Participant, as the case may
 be, with all such information as may be reasonably required from the Owner
 Participant or the Owner Trustee, as the case may be, in connection with
 the preparation of such income tax returns.

                                ARTICLE VII

                      INDEMNIFICATION OF OWNER TRUSTEE
                            BY OWNER PARTICIPANT

           SECTION 7.01   OWNER PARTICIPANT TO INDEMNIFY OWNER TRUSTEE. The
 Owner Participant hereby agrees, whether or not any of the transactions
 contemplated hereby shall be consummated, to assume liability for, and
 hereby indemnify, protect, save and keep harmless FSB in its individual
 capacity and its successors, assigns, legal representatives, agents and
 servants, from and against any and all liabilities, obligations, losses,
 damages, penalties, taxes (excluding any taxes payable by FSB in its
 individual capacity on or measured by any compensation received by FSB in
 its individual capacity for its services hereunder or in connection with
 the transactions contemplated by the Operative Documents), claims, actions,
 suits, costs, expenses or disbursements (including, without limitation,
 reasonable ongoing fees of the Owner Trustee, reasonable legal fees and
 expenses, and including without limitation any liability of an owner, any
 strict liability and any liability without fault) of any kind and nature
 whatsoever which may be imposed on, incurred by or asserted against FSB in
 its individual capacity (whether or not also indemnified against by Lessee
 under the Lease or under the Participation Agreement or also indemnified
 against by any other person but only to the extent not otherwise paid or
 reimbursed by Lessee or such other person) in any way relating to or
 arising out of this Trust Agreement or any of the Operative Documents or
 the enforcement of any of the terms of any thereof, or in any way relating
 to or arising out of the manufacture, purchase, acceptance, nonacceptance,
 rejection, ownership, delivery, lease, possession, use, operation,
 condition, sale, return or other disposition of the Aircraft (including,
 without limitation, latent and other defects, whether or not discoverable,
 and any claim for patent, trademark or copyright infringement), or in any
 way relating to or arising out of the administration of the Trust Estate or
 the action or inaction of the Owner Trustee or FSB in its individual
 capacity hereunder, except (a) in the case of willful misconduct or gross
 negligence on the part of the Owner Trustee or FSB in its individual
 capacity in the performance or nonperformance of its duties hereunder or
 (b) those resulting from the inaccuracy of any representation or warranty
 of FSB in its individual capacity (or from the failure of FSB in its
 individual capacity to perform any covenant) in Section 6.03 hereof, in
 Section 6.03 of the Trust Indenture or, with respect to representations or
 warranties of FSB in its individual capacity only, in Section 4 of the
 Lease, in Sections 7(a), 7(b), 7(f), 7(g), 7(m), 7(o), 7(p), 7(s) or 7(u)
 of the Participation Agreement or in any of the other Operative Documents
 or (c) as may result from a breach by FSB in its individual capacity of its
 covenants in the last sentence of Section 5.04 hereof or (d) in the case of
 the failure to use ordinary care on the part of the Owner Trustee or FSB in
 its individual capacity in the disbursement of funds. The indemnities
 contained in this Section 7.01 extend to FSB only in its individual
 capacity and shall not be construed as indemnities of the Trust Indenture
 Estate or the Trust Estate (except to the extent, if any, that FSB in its
 individual capacity has been reimbursed by the Trust Indenture Estate or
 the Trust Estate for amounts covered by the indemnities contained in this
 Section 7.01). The indemnities contained in this Section 7.01 shall survive
 the termination of this Trust Agreement. In addition, if necessary, FSB in
 its individual capacity shall be entitled to indemnification from the Trust
 Estate, subject to the Lien of the Trust Indenture, for any liability,
 obligation, loss, damage, penalty, tax, claim, action, suit, cost, expense
 or disbursement indemnified against pursuant to this Section 7.01 to the
 extent not reimbursed by Lessee, the Owner Participant or others, but
 without releasing any of them from their respective agreements of
 reimbursement; and to secure the same FSB in its individual capacity shall
 have a Lien on the Trust Estate, subject to the Lien of the Trust
 Indenture, which shall be prior to any interest therein of the Owner
 Participant. The payor of any indemnity under this Article VII shall be
 subrogated to any right of the person indemnified in respect of the matter
 as to which such indemnity was paid.

                                ARTICLE VIII

                TRANSFER OF THE OWNER PARTICIPANT'S INTEREST

           SECTION 8.01   TRANSFER OF INTERESTS.  All provisions of Section
 7(k) of the Participation Agreement shall (with the same force and effect
 as if set forth in full, mutatis, in this Section 8.01) be applicable to
 any assignment, conveyance or other transfer by any Owner Participant of
 its right, title or interest in and to the Participation Agreement, the
 Trust Estate or this Trust Agreement.  In addition to the provisions of
 Section 7(k) of the Participation Agreement:  (i) any such transfer shall
 be effected by a written agreement, in form and substance reasonably
 satisfactory to the Owner Trustee in its individual capacity, among such
 transferee, its transferor and the Owner Trustee, which shall provide that
 such transferee thereby becomes a party to, and beneficiary of, this Trust
 Agreement and an Owner Participant for all purposes hereof and that such
 transferee assumes all of the obligations of its transferor under this
 Trust Agreement; and (ii) so long as the Lease shall be in effect or any
 Equipment Notes remain unpaid, such transferee and its transferor shall
 have complied with all of the terms of Section 7(k) of the Participation
 Agreement.

                                 ARTICLE IX

                   SUCCESSOR OWNER TRUSTEES; CO-TRUSTEES

           SECTION 9.01   RESIGNATION OF OWNER TRUSTEE; APPOINTMENT OF
 SUCCESSOR. (a) Resignation or Removal. The Owner Trustee or any successor
 Owner Trustee (i) shall resign if required to do so pursuant to Section
 7(a) of the Participation Agreement and (ii) may resign at any time without
 cause by giving at least sixty (60) days' prior written notice to the Owner
 Participant, the Indenture Trustee (so long as the Lien of the Trust
 Indenture has not been fully discharged) and Lessee (so long as the Lease
 is in effect), such resignation to be effective upon the acceptance of
 appointment by the successor Owner Trustee under Section 9.01(b) hereof. In
 addition, the Owner Participant may at any time remove the Owner Trustee
 without cause by a notice in writing delivered to the Owner Trustee, the
 Indenture Trustee (so long as the Lien of the Trust Indenture has not been
 fully discharged) and Lessee (so long as the Lease is in effect), such
 removal to be effective upon the acceptance of appointment by the successor
 Owner Trustee under Section 9.01(b) hereof. In the case of the resignation
 or removal of the Owner Trustee, the Owner Participant may appoint a
 successor Owner Trustee by an instrument signed by the Owner Participant.
 If a successor Owner Trustee shall not have been appointed within thirty
 (30) days after such notice of resignation or removal, the Owner Trustee,
 the Owner Participant, Lessee or the Indenture Trustee may apply to any
 court of competent jurisdiction to appoint a successor Owner Trustee to act
 until such time, if any, as a successor shall have been appointed as above
 provided. Any successor Owner Trustee so appointed by such court shall
 immediately and without further act be superseded by any successor Owner
 Trustee appointed as above provided.

           (b)  Execution and Delivery of Documents, etc. Any successor
 Owner Trustee, however appointed, shall execute and deliver to the
 predecessor Owner Trustee and the Owner Participant an instrument accepting
 such appointment, and thereupon such successor Owner Trustee, without
 further act, shall become vested with all the estates, properties, rights,
 powers, duties and trusts of the predecessor Owner Trustee in the trusts
 hereunder with like effect as if originally named the Owner Trustee herein;
 but nevertheless, upon the written request of such successor Owner Trustee,
 such predecessor Owner Trustee shall execute and deliver an instrument
 transferring to such successor Owner Trustee, upon the trusts herein
 expressed, all the estates, properties, rights, powers and trusts of such
 predecessor Owner Trustee, and such predecessor Owner Trustee shall duly
 assign, transfer, deliver and pay over to such successor Owner Trustee all
 monies or other property then held by such predecessor Owner Trustee upon
 the trusts herein expressed. Upon the appointment of any successor Owner
 Trustee hereunder, the predecessor Owner Trustee will execute such
 documents as are provided to it by such successor Owner Trustee and will
 take such further actions as are requested of it by such successor Owner
 Trustee as are reasonably required to cause registration of the Aircraft
 included in the Trust Estate to be transferred upon the records of the
 Federal Aviation Administration, or other governmental authority having
 jurisdiction, into the name of the successor Owner Trustee.

           (c)  Qualification. Any successor Owner Trustee, however
 appointed, shall be a Citizen of the United States without making use of a
 voting trust, voting powers agreement or similar arrangement and shall also
 be a bank or trust company organized under the laws of the United States or
 any state thereof having a combined capital and surplus of at least
 $100,000,000, if there be such an institution willing, able and legally
 qualified to perform the duties of the Owner Trustee hereunder upon
 reasonable or customary terms.

           (d)  Merger, etc. Any corporation into which the Owner 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 Owner Trustee shall be a party, or any corporation to which
 substantially all the corporate trust business of the Owner Trustee may be
 transferred, shall, subject to the terms of Section 9.01(c) hereof, be the
 Owner Trustee hereunder without further act.

           SECTION 9.02   CO-TRUSTEES AND SEPARATE TRUSTEES. If at any time
 it shall be necessary or prudent in order to conform to any law of any
 jurisdiction in which all or any part of the Trust Estate is located, or
 the Owner Trustee being advised by counsel shall determine that it is so
 necessary or prudent in the interest of the Owner Participant or the Owner
 Trustee, or the Owner Trustee shall have been directed to do so by the
 Owner Participant, the Owner Trustee and the Owner Participant shall
 execute and deliver an agreement supplemental hereto and all other
 instruments and agreements necessary or proper to constitute another bank
 or trust company or one or more persons (any and all of which shall be a
 Citizen of the United States without making use of a voting trust, voting
 powers agreement or similar arrangement) approved by the Owner Trustee and
 the Owner Participant, either to act as co-trustee, jointly with the Owner
 Trustee, or to act as separate trustee hereunder (any such co-trustee or
 separate trustee being herein sometimes referred to as an "additional
 trustee").

           Every additional trustee hereunder shall, to the extent permitted
 by law, be appointed and act, and the Owner Trustee and its successors
 shall act, subject to the following provisions and conditions:

           (A)  all powers, duties, obligations and rights conferred upon
      the Owner Trustee in respect of the custody, control and management of
      monies, or documents authorized to be delivered hereunder or under the
      Participation Agreement shall be exercised solely by the Owner
      Trustee;

           (B)  all other rights, powers, duties and obligations conferred
      or imposed upon the Owner Trustee shall be conferred or imposed upon
      and exercised or performed by the Owner Trustee and such additional
      trustee jointly, except to the extent that under any law of any
      jurisdiction in which any particular act or acts are to be performed
      (including the holding of title to the Trust Estate) the Owner 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 additional trustee;

           (C)  no power given to, or which it is provided hereby may be
      exercised by, any such additional trustee shall be exercised hereunder
      by such additional trustee, except jointly with, or with the consent
      in writing of, the Owner Trustee;

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

           (E)  the Owner Participant, at any time, by an instrument in
      writing may remove any such additional trustee; and

           (F)  no appointment of, or action by, any additional trustee will
      relieve the Owner Trustee of any of its obligations under, or
      otherwise affect any of the terms of, the Trust Indenture or affect
      the interests of the Indenture Trustee or the holders of the Equipment
      Notes in the Trust Indenture Estate.

 provisions of any of the above documents, requires the consent of any other
 party unless such consent shall have been obtained.

           (b)  Delivery of Amendments and Supplements to Certain Parties. A
 signed copy of each amendment or supplement referred to in Section 10.01(a)

 executing any document required to be executed by it pursuant to the terms
 of Section 10.01 hereof, the Owner Trustee shall be entitled to receive an
 opinion of its counsel to the effect that the execution of such document is
 authorized hereunder. If in the opinion of the Owner Trustee any such
 document adversely affects any right, duty, immunity or indemnity in favor
 of the Owner Trustee hereunder or under any other Operative Document to
 which the Owner Trustee is a party, the Owner Trustee may in its discretion
 decline to execute such document.

           SECTION 10.03  ABSENCE OF REQUIREMENTS AS TO FORM. It shall not
 be necessary for any written request furnished pursuant to Section 10.01
 hereof to specify the particular form of the proposed documents to be
 executed pursuant to such Section, but it shall be sufficient if such

 failure of the Owner Trustee to mail such conformed copy shall not impair
 or affect the validity of such document.

           SECTION 10.05  NO REQUEST NEEDED AS TO LEASE SUPPLEMENT AND TRUST
 SUPPLEMENT. No written request pursuant to Section 10.01 hereof shall be
 required to enable the Owner Trustee to enter into the Lease Supplement
 covering the Aircraft with Lessee pursuant to the terms of the Lease and
 Section 3.01 hereof and the Trust Supplement pursuant to the terms of the
 Trust Indenture and Section 3.01 hereof.

 to an accounting or to the transfer of legal title to any part of the Trust
 Estate.

           SECTION 11.03  ASSIGNMENT, SALE, ETC. OF AIRCRAFT. Any
 assignment, sale, transfer or other conveyance of its interest in the
 Aircraft by the Owner Trustee made pursuant to the terms hereof or of the
 Lease or the Participation Agreement shall bind the Owner Participant and

 the Owner Trustee and the Owner Participant in and to the Aircraft. No
 purchaser or other grantee shall be required to inquire as to the
 authorization, necessity, expediency or regularity of such assignment,
 sale, transfer or conveyance or as to the application of any sale or other

 respect of this Trust Agreement; but this Trust Agreement shall be held to
 be for the sole and exclusive benefit of the Owner Trustee and the Owner
 Participant.

           SECTION 11.05  NOTICES; CONSENT TO JURISDICTION. (a) All notices,

 of any thereof or any of the transactions contemplated hereby or thereby
 brought by any party or parties thereto, or their successors or assigns,
 and (B) hereby waives, and agrees not to assert, by way of motion, as a
 defense, or otherwise, in any such suit, action or proceeding, to the
 extent permitted by applicable law, that the suit, action or proceeding is
 brought in an inconvenient forum, that the venue of the suit, action or
 proceeding is improper, or that the Participation Agreement, the Lease, the
 Tax Indemnity Agreement or any other Operative Document or the subject
 matter of any thereof or any of the transactions contemplated hereby or
 thereby may not be enforced in or by such courts.

           SECTION 11.06  SEVERABILITY. Any provision hereof 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, and
 any such prohibition or unenforceability in any jurisdiction shall not
 invalidate or render unenforceable such provision in any other
 jurisdiction.

 instrument or action by the Owner Participant shall bind its successors and
 assigns. Any Owner Participant which shall cease to have any ownership
 interest shall thereupon cease to be a party hereto or an Owner Participant
 for any reason and shall have no further obligations hereunder.

 or (3) the willful misconduct or the gross negligence of such Indemnitee,
 or (4) (A) in the case of any Indemnitee, the offer, sale or other
 disposition (voluntary or involuntary) by such Indemnitee of all or any
 part of its interest in the Airframe or any Engine, (B) in the case of a
 Note Holder, the offer, sale or other disposition (voluntary or
 involuntary) by such Note Holder of all or any part of its interest in any
 Equipment Note or (C) in the case of any Indemnitee, the offer, sale or
 other disposition by such Indemnitee of all or any part of such
 Indemnitee's interest in the Operative Documents, or (5) any Tax, or (6) in
 the case of the Indenture Trustee in its individual and trust capacities,
 failure on the part of the Indenture Trustee to distribute in accordance
 with the Indenture any amounts distributable by it thereunder, or (7) in
 the case of any Pass Through Trustee or the Subordination Agent, failure on
 the part of such Pass Through Trustee or the Subordination Agent to
 distribute in accordance with the Intercreditor Agreement and the Pass
 Through Trust Agreement amounts received and distributable thereunder, or
 (8) the authorization or giving or withholding of any future amendments,
 supplements, waivers or consents with respect to any of the Operative
 Documents which amendments, supplements, waivers or consents (a) are not or
 were not requested by Owner or (b) are not occasioned by a specific
 requirement of the Operative Documents, or (9) any amount which any
 Indemnitee expressly agrees to pay under any Operative Document or any
 amount which is expressly stated to be an expense that is not reimbursable
 by Owner under the Operative Documents, or (10) any amount that is an
 ordinary and usual operating or overhead expense of any Indemnitee (it
 being understood out-of-pocket expenses payable to third parties do not
 constitute "ordinary and usual operating and overhead expenses"), or (11)
 any amounts attributable to any Lien which such Indemnitee is required to
 remove pursuant to the terms of the Operative Documents or the Pass Through
 Documents, or (12) any loss of tax benefits or increases in tax liability
 or (13) any amount that constitutes principal of, or interest or premium on
 the Equipment Notes.

           Owner's indemnity obligation to an Indemnitee under this Section
 6(b) shall equal the amount which, after taking into account any Tax
 imposed upon the receipt or accrual of the amounts payable under this
 Section 6(b) and any tax benefits realized by such Indemnitee as a result
 of the accrual or payment of such Expense shall equal the amount of the
 Expense indemnifiable under this Section 6(b).

           If any Indemnitee shall realize a tax savings by reason of any
 Tax paid or indemnified by Owner pursuant to this Section 6(b) (whether
 such tax savings shall be by means of a foreign tax credit, depreciation or
 cost recovery deduction or otherwise) and such savings are not otherwise
 taken into account in computing such payment or indemnity such Indemnitee
 shall pay to Owner an amount equal to the lesser of (i) the amount of such
 tax savings, plus any additional tax savings recognized as the result of
 any payment made pursuant to this sentence, when, as if, and to the extent,
 realized or (ii) the amount of all payments pursuant to this Section 6(b)
 by Owner to such Indemnitee (less any payments previously made by such
 Indemnitee to Owner pursuant to this Section 6(b)) (and the excess, if any,
 of the amount described in clause (i) over the amount described in clause
 (ii) shall be carried forward and applied to reduce pro tanto any
 subsequent obligations of Owner to make payments to such Indemnitee
 pursuant to this Section 6(b)).

           If a claim is made against an Indemnitee involving one or more
 Expenses and such Indemnitee has notice thereof, such Indemnitee shall
 promptly after receiving such notice give notice of such claim to Owner;
 provided that the failure to give such notice shall not affect the
 obligations of Owner hereunder except to the extent Owner is prejudiced by
 such failure or Owner's indemnification obligations are increased as a
 result of such failure.  If no Event of Default shall have occurred and be
 continuing, Owner shall be entitled, at its sole cost and expense, acting
 through counsel reasonably acceptable to the respective Indemnitee, (A) in
 any judicial or administrative proceeding that involves solely a claim for
 one or more expenses, to assume responsibility for and control thereof, (B)
 in any judicial or administrative proceeding involving a claim for one or
 more expenses and other claims related or unrelated to the transactions
 contemplated by the Operative Documents, to assume responsibility for and
 control of such claim for Expenses to the extent that the same may be and
 is severed from such other claims (and such Indemnitee shall use its best
 efforts to obtain such severance) and (C) in any other case, to be
 consulted by such Indemnitee with respect to judicial proceedings subject
 to the control of such Indemnitee and to be allowed, at Owner's sole
 expense, to participate therein.  Notwithstanding any of the foregoing to
 the contrary, Owner shall not be entitled to assume responsibility for and
 control of any such judicial or administrative proceedings if such
 proceedings will involve a material risk of the sale, forfeiture or loss
 of, or the creation of any Lien (other than a Permitted Lien) on, the
 Aircraft, the Indenture Estate or any part thereof unless in such an event
 Owner shall have posted a bond or other security satisfactory to the
 relevant Indemnitees in respect to such risk.  The Indemnitee may
 participate at its own expense and with its own counsel in any judicial
 proceeding controlled by Owner pursuant to the preceding provisions.

           The affected Indemnitee shall supply Owner with such information
 reasonably requested by Owner as is necessary or advisable for Owner to
 control or participate in any proceeding to the extent permitted by this
 Section 6(b). Such Indemnitee shall not enter into a settlement or other
 compromise with respect to any Expense without the prior written consent of
 Owner, which consent shall not be unreasonably withheld or delayed, unless
 such Indemnitee waives its right to be indemnified with respect to such
 Expense under this Section 6(b).

           Owner shall supply the Indemnitee with such information
 reasonably requested by the Indemnitee as is necessary or advisable for the
 Indemnitee to control or participate in any proceeding to the extent
 permitted by this Section 6(b).

           Upon payment of any Expense pursuant to this Section 6(b), Owner,
 without any further action, shall be subrogated to any claims the
 Indemnitee may have relating thereto.  The Indemnitee agrees to give such
 further assurances or agreements and to cooperate with Owner to permit
 Owner to pursue such claims, if any, to the extent reasonably requested by
 Owner.

           If an Indemnitee is reimbursed, in whole or in part, with respect
 to any Expense paid by Owner hereunder, it will promptly pay the amount
 refunded, including interest received thereon (but not an amount in excess
 of the amount Owner or any of its insurers has paid in respect of such
 Expense pursuant to this Section 6(b)) over to Owner.

           To the extent permitted by applicable law, interest at the Base
 Rate plus  one percent (1.0%) shall be paid, on demand, on any amount or
 indemnity not paid when due pursuant to this Section 6 until the same shall
 be paid.  Such interest shall be paid in the same manner as the unpaid
 amount in respect of which such interest is due.

           Any amount which is payable to Owner by any Person pursuant to
 this Section 6(b) shall not be paid to Owner if an Event of Default has
 occurred and is continuing or if any payment is due and owing by Owner to
 such Person under any Operative Document. Any such amount shall be held by
 such Person (Owner hereby granting a security interest in such amount to
 such Person) and, if an Event of Default shall have occurred and be
 continuing, shall be applied against Owner's obligations hereunder to such
 Person as and when due (and, to the extent that Owner has no obligations
 hereunder to such Person, such amount shall be paid to Owner).  At such
 time as there shall not be continuing any such Event of Default or there
 shall not be due and owing any such payment, such amount shall be paid to
 Owner to the extent not previously applied in accordance with the
 immediately preceding sentence.

      SECTION 7.  REPRESENTATIONS, WARRANTIES AND COVENANTS.

           (a)  Securities Act.  Each Loan Participant represents and
 warrants that neither it nor anyone acting in its behalf has offered any
 Equipment Notes for sale to, or solicited any offer to buy any Equipment
 Note from, any Person or entity other than in a manner in compliance with,
 and which does not require registration under, the Securities Act or the
 rules and regulations thereunder.

           (b)  Reregistration.  The Indenture Trustee and each Loan
 Participant agree that, so long as no Event of Default shall have occurred
 and be continuing, Owner may elect to effect a change in registration of
 the Aircraft, at Owner's cost and expense, so long as the country of
 registry of the Aircraft is a country listed on Exhibit A.  Upon the
 request of Owner, Exhibit A shall be amended from time to time to include
 any other country which the Indenture Trustee has determined, acting
 reasonably, would provide substantially equivalent protection for the
 rights of lenders in similar transactions as provided under the laws of the
 United States of America and the states thereof.  In order for Owner to
 effect a change in the country of registry of the Aircraft, Owner shall
 deliver to the Indenture Trustee the following:

      (I)  an Officer's Certificate certifying that (A) the insurance or
           self-insurance required by Section 7.04 of the Indenture shall be
           in full force and effect at the time of such change in
           registration after giving effect to such change in registration,
           (B) all indemnities in favor of the Indenture Trustee under any
           Operative Document afford the Indenture Trustee substantially the
           same protection as provided prior to such change of registry, (C)
           the Lien of the Indenture in favor of the Indenture Trustee will
           continue as a first priority lien following such change of
           registry, (D) such change will not result in the imposition of,
           or increase in the amount of, any Tax for which Owner is not
           required to indemnify, or is not then willing to enter into a
           binding agreement to indemnify, the Note Holders or the Indenture
           Trustee, pursuant to this Agreement and  (E) that the new country
           of registry imposes aircraft maintenance standards not materially
           different from those of any Permitted Foreign Air Authority; and

      (II) a favorable opinion (subject to customary exceptions) of counsel
           (reasonably acceptable to the Indenture Trustee) addressed to the
           Indenture Trustee, from counsel of recognized reputation
           qualified in the laws of the relevant jurisdiction to the effect
           that: (A) it is not necessary, solely as a consequence of such
           change in registration and without giving effect to any other
           activity of the Indenture Trustee (or any Affiliate thereof) for
           the Indenture Trustee to register or qualify to do business in
           such jurisdiction; (B) unless Owner shall have agreed to provide
           insurance covering the risk of requisition of use of such
           Aircraft by the government of such jurisdiction so long as such
           Aircraft is registered under the laws of such jurisdiction, the
           laws of such jurisdiction require fair compensation by the
           government of such jurisdiction payable in currency freely
           convertible into Dollars for the loss of use of such Aircraft in
           the event of the requisition by such government of such use; and
           (C) after giving effect to such change in registration, the Lien
           of the Indenture on Owner's right, title and interest in and to
           the Aircraft shall continue as a valid and duly perfected first
           priority security interest and all filing, recording or other
           action necessary to protect the same shall have been accomplished
           (or, if such opinion cannot be given at the time of such proposed
           change in registration because such change in registration is not
           yet effective, (1) the opinion shall detail what filing,
           recording or other action is necessary and (2) the Indenture
           Trustee shall have received a certificate from Owner that all
           possible preparations to accomplish such filing, recording and
           other action shall have been done, and such filing, recording and
           other action shall be accomplished and a supplemental opinion to
           that effect shall be delivered to the Indenture Trustee on or
           prior to the effective date of such change in registration).

           Owner shall pay all reasonable costs, expenses, fees, recording
 and registration taxes, including the reasonable fees and expenses of
 counsel to the  Indenture Trustee, and other charges in connection with any
 such change in registration.

           (c)  Quiet Enjoyment.  Each Loan Participant and each of the
 Indenture Trustee, the Subordination Agent and the Pass Through Trustee
 covenants and agrees that, so long as no Event of Default shall have
 occurred and be continuing and the Indenture has not been duly declared in
 default, such Person shall not (and shall not permit any Affiliate or other
 Person claiming by, through or under it to) interfere with Owner's
 continued possession, use and operation of, and quiet enjoyment of, the
 Aircraft.

           (d)  Equipment Notes Acquired for Investment.  Each Loan
 Participant represents and warrants that the Equipment Note to be issued to
 it pursuant to the Indenture is being acquired by it for investment and not
 with a view to resale or distribution (it being understood that such Loan
 Participant may pledge or assign as security its interest in each Equipment
 Note issued to it), except that the Loan Participants may sell, transfer or
 otherwise dispose of any Equipment Note or any portion thereof, or grant
 participations therein, in a manner which in itself does not require
 registration under the Securities Act.

           (e)  Owner Merger Covenant.  Owner will not consolidate with or
 merge into any other corporation or convey, transfer or lease substantially
 all of its assets as an entirety to any Person unless:

           (i)  the corporation formed by such consolidation or into which
      Owner is merged or the Person which acquires by conveyance, transfer
      or lease substantially all of the assets of Owner as an entirety shall
      be (i) organized and validly existing under the laws of the United
      States of America or any state thereof or the District of Columbia,
      (ii) a Citizen of the United States and (iii) a Certificated Air
      Carrier, if and so long as such status is a condition of entitlement
      to the benefits of Section 1110 of the Bankruptcy Code with respect to
      the Lien of the Indenture;

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

           (iii) immediately after giving effect to such transaction, no
      Event of Default shall have occurred and be continuing; and

           (iv) Owner shall have delivered to the Indenture Trustee a
      certificate signed by the President, any Executive Vice President, any
      Senior Vice President or any Vice President and by the Secretary or an
      Assistant Secretary of Owner, and an opinion of counsel (which may be
      Owner's General Counsel, Deputy General Counsel, Associate General
      Counsel or Assistant General Counsel) reasonably satisfactory to the
      Indenture Trustee, each stating that such consolidation, merger,
      conveyance, transfer or lease and the assumption agreement mentioned
      in clause (ii) above comply with this Section 7(e) and that all
      conditions precedent herein provided for relating to such transaction
      have been complied with.

           Upon any such consolidation or merger or any such conveyance,
 transfer or lease of substantially all of the assets of Owner as an
 entirety in accordance with this Section 7(e), the successor corporation or
 Person formed by such consolidation or into which Owner 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, Owner under
 this Agreement with the same effect as if such successor corporation or
 Person had been named as Owner herein.  No such conveyance, transfer or
 lease of substantially all of the assets of Owner as an entirety shall have
 the effect of releasing Owner or any successor corporation or Person which
 shall theretofore have become such in the manner prescribed in this Section
 7(e) from its liability in respect of any Operative Document to which it is
 a party.

           (f)  Representations, Warranties and Covenants of the Indenture

      (without making use of any voting trust, voting powers agreement or
      similar arrangement) is likely to change and will resign as Indenture
      Trustee as provided in Section 9.02 of the Indenture promptly after it
      obtains actual knowledge that it has ceased to be such a Citizen of
      the United States (without making use of a voting trust, voting powers
      agreement or similar arrangement), and has the full corporate power,
      authority and legal right under the laws of the State of Connecticut
      and the United States pertaining to its banking, trust and fiduciary
      powers to execute and deliver each of this Agreement, the Indenture

           (iii) this Agreement and each of the other Indenture Trustee
      Documents constitute the legal, valid and binding obligations of the
      Indenture Trustee enforceable against it in accordance with their
      respective terms, except as the same may be limited by applicable
      bankruptcy, insolvency, reorganization, moratorium or similar laws
      affecting the rights of creditors generally and by general principles
      of equity, whether considered in a proceeding at law or in equity;

           (iv) there are no pending or, to its knowledge, threatened
      actions or proceedings against the Indenture Trustee, either in its
      individual capacity or as Indenture Trustee, before any court or
      administrative agency which, if determined adversely to it, would
      materially adversely affect the ability of the Indenture Trustee, in
      its individual capacity or as Indenture Trustee as the case may be, to
      perform its obligations under the Operative Documents to which it is a
      party; and

           (v)  there are no Indenture Trustee Liens on the Aircraft.

           (g)  Confidentiality of Purchase Agreement.  The Indenture

 with the prior written consent of the Manufacturer, the Seller and Owner or

 actual diminution of the assets of Owner resulting from such Loan
 Participant Lien attributable to it.

           (i)  Indenture Trustee Liens.  State Street Bank and Trust

 interests created by the Indenture or will furnish to the Indenture Trustee
 timely notice of the necessity of such action, together with such

      affecting the rights of creditors generally and by general principles
      of equity, whether considered in a proceeding at law or in equity;

           (iii) none of the execution, delivery and performance by the

      Through Trustee of the Equipment Notes pursuant to this Agreement, or
      the issuance of the Pass Through Certificates pursuant to the Pass
      Through Trust Agreements, contravenes any law, rule or regulation of
      the State of Connecticut or any United States governmental authority
      or agency regulating the Pass Through Trustee's banking, trust or
      fiduciary powers or any judgment or order applicable to or binding on
      the Pass Through Trustee and does not contravene or result in any
      breach of, or constitute a default under, the Pass Through Trustee's
      articles of association or by-laws or any agreement or instrument to
      which the Pass Through Trustee is a party or by which it or any of its
      properties may be bound;

           (iv) neither the execution and delivery by the Pass Through
      Trustee of any of the Pass Through Trust Agreements, the Intercreditor
      Agreement or this Agreement, nor the consummation by the Pass Through

      requires the consent or approval of, the giving of notice to, the
      registration with, or the taking of any other action with respect to,
      any Connecticut governmental authority or agency or any Federal
      governmental authority or agency regulating the Pass Through Trustee's
      banking, trust or fiduciary powers;

           (v)  there are no Taxes payable by the Pass Through Trustee
      imposed by the State of Connecticut or any political subdivision or
      taxing authority thereof in connection with the execution, delivery
      and performance by the Pass Through Trustee of this Agreement, any of
      the Pass Through Trust Agreements or the Intercreditor Agreement
      (other than franchise or other taxes based on or measured by any fees
      or compensation received by the Pass Through Trustee for services
      rendered in connection with the transactions contemplated by any of
      the Pass Through Trust Agreements), and there are no Taxes payable by
      the Pass Through Trustee imposed by the State of Connecticut or any
      political subdivision thereof in connection with the acquisition,
      possession or ownership by the Pass Through Trustee of any of the
      Equipment Notes (other than franchise or other taxes based on or
      measured by any fees or compensation received by the Pass Through
      Trustee for services rendered in connection with the transactions
      contemplated by any of the Pass Through Trust Agreements), and,
      assuming that the trusts created by the Pass Through Trust Agreements
      will not be taxable as corporations, but rather, each will be
      characterized either as a grantor trust under subpart E, Part I, of
      Subchapter J of the Code or as a partnership, such trusts will not be
      subject to any Taxes imposed by the State of Connecticut or any
      political subdivision thereof;

           (vi) there are no pending or threatened actions or proceedings
      against the Pass Through Trustee before any court or administrative
      agency which individually or in the aggregate, if determined adversely
      to it, would materially adversely affect the ability of the Pass
      Through Trustee to perform its obligations under this Agreement, the
      Intercreditor Agreement or any Pass Through Trust Agreement;

           (vii) except for the issue and sale of the Pass Through
      Certificates contemplated hereby, the Pass Through Trustee has not
      directly or indirectly offered any Equipment Note for sale to any
      Person or solicited any offer to acquire any Equipment Notes from any

           (iv) neither the execution and delivery by the Subordination
      Agent of any of the Liquidity Facilities, the Policy Provider
      Agreement, the Intercreditor Agreement or this Agreement nor the
      consummation by the Subordination Agent of any of the transactions

      taxing authority thereof in connection with the execution, delivery
      and performance by the Subordination Agent of this Agreement, any of
      the Liquidity Facilities, the Policy Provider Agreement or the
      Intercreditor Agreement (other than franchise or other taxes based on
      or measured by any fees or compensation received by the Subordination
      Agent for services rendered in connection with the transactions
      contemplated by the Intercreditor Agreement, the Policy Provider
      Agreement or any of the Liquidity Facilities), and there are no Taxes
      payable by the Subordination Agent imposed by the State of Connecticut
      or any political subdivision thereof in connection with the
      acquisition, possession or ownership by the Subordination Agent of any

      contemplated by the Intercreditor Agreement, the Policy Provider
      Agreement or any of the Liquidity Facilities);

           (vi) there are no pending or threatened actions or proceedings
      against the Subordination Agent before any court or administrative
      agency which individually or in the aggregate, if determined adversely
      to it, would materially adversely affect the ability of the
      Subordination Agent to perform its obligations under this Agreement,
      the Intercreditor Agreement, the Policy Provider Agreement or any
      Liquidity Facility;

           (vii) the Subordination Agent has not directly or indirectly
      offered any Equipment Note for sale to any Person or solicited any
      offer to acquire any Equipment Notes from any Person, nor has the

      Provider Agreement or Liquidity Facility; and

           (viii) the Subordination Agent is not directly or indirectly
      controlling, controlled by or under common control with Owner.

           In our examination, we have assumed the genuineness of all
 signatures, including indorsements, the legal capacity of natural persons,
 the authenticity of all documents submitted to us as originals, the
 conformity to original documents of all copies submitted to us as

 Trustee and their respective officers and representatives, and others in
 the Operative Documents and of public officials, including the facts and
 conclusions set forth in the Company's Certificate described below, and we

 Delaware corporation ("Shuttle");](1)
 ---------------
 (1)  For Aircraft with Shuttle, Inc. Lease only.

          (i)  an unfiled, but signed copy of a financing statement naming
 "US Airways, Inc." as debtor and "State Street Bank and Trust Company of
 Connecticut, as Indenture Trustee" as secured party, which we understand
 will be filed within ten (10) days of the transfer of the security interest
 in the Offices of the Secretary of State of the State of New York (such
 filing Office, the "New York Filing Office" and such financing statement,
 the "New York Financing Statement");

          (j)  unfiled, but signed financing statements naming "US Airways,
 Inc." as debtor and "State Street Bank and Trust Company of Connecticut, as
 Indenture Trustee" as secured party, which we understand will be filed
 within ten (10) days of the transfer of the security interest in the
 offices of State Corporation Commission, Virginia and the Arlington County
 Clerk (such filing offices, the "Virginia Filing Offices" and such
 financing statements, the "Virginia Financing Statements");

          (k)  a certificate of US Airways, dated the date hereof, a copy of
 which is attached as Exhibit A; and

          (l)  such other documents as we have deemed necessary or
 appropriate as a basis for the opinions set forth below.

          We express no opinion as to the laws of any jurisdiction other
 than (i) the Applicable Laws of the State of New York, (ii) the Applicable
 Laws of the United States of America and (iii) Article 9 of the Virginia
 UCC (as defined below).  In this respect, we call to your attention that
 certain of the Operative Documents are governed by laws of jurisdictions
 other than those described above and we express no opinion as to the effect
 of any such laws on the opinions expressed herein.  In addition, we express
 no opinion with respect to the Transportation Code or the rules and
 regulations of the Federal Aviation Administration or the effect thereof on
 the opinions herein stated.  In addition, we call to your attention that
 we are not admitted to practice in the Commonwealth of Virginia and our
 opinions in paragraph 8 with respect to the laws of such Commonwealth is
 based solely on our review of the Uniform Commercial Code in effect on the
 date hereof in the Commonwealth of Virginia (the "Virginia UCC") as
 published in the CCH Secured Transactions Guide without regard to case law
 decided thereunder.

          Capitalized terms not otherwise defined herein have the meanings
 assigned thereto in Annex A to the Participation Agreement.  The documents
 referred to in (a) through (g) above shall hereinafter be referred to
 collectively as the "Transaction Documents."  "Applicable Laws" shall mean
 those laws, rules, regulations which, in our experience, are normally
 applicable to transactions of the type contemplated by the Transaction
 Documents, without our having made any special investigation as to the
 applicability of any special law, rule or regulation, and which are not the
 subject of a specific opinion herein referring to a particular law or laws.
 "Governmental Approval" means any consent, approval, license, authorization
 or validation of, or filing, recording or registration with, any
 governmental authority pursuant to Applicable Laws.  Unless otherwise
 indicated, the "New York UCC" means the Uniform Commercial Code as in
 effect on the date hereof in the State of New York and "Applicable UCC"
 means the New York UCC and the Virginia UCC, as applicable.

          Based upon the foregoing, and subject to the limitations,
 qualifications, exceptions and assumptions set forth herein, we are of the
 opinion that:

          2.  Each of the Transaction Documents constitutes the valid and
 binding obligation of US Airways enforceable against US Airways in
 accordance with its terms under the laws of the State of New York.  The
 Indenture and the Indenture Supplement constitute valid and binding
 obligations of the Indenture Trustee enforceable against the Indenture
 Trustee in accordance with their terms under the laws of the State of New
 York.

          3.  Neither the execution and delivery by US Airways of the
 Transaction Documents nor the compliance by US Airways with the terms and
 provisions thereof will contravene any Applicable Law of the State of New
 York or any Applicable Law of the United States of America.

          4.  Except for (a) the due and timely filing and, where
 appropriate, recording of the Indenture (with the Indenture Supplement
 covering the Aircraft attached as an exhibit), pursuant to the
 Transportation Code, (b) the registration of the issuance and sale of the
 Pass Through Certificates under the Securities Act, (c) compliance with the
 securities law of each applicable state and (d) filing of appropriate UCC
 Financing Statements and continuation statements, no Governmental Approval,
 which has not been obtained or taken and is not in full force and effect,
 is required in connection with the execution, delivery or enforceability by
 US Airways of any of the Transaction Documents.

          5.  No registration of US Airways or any of the Pass Through
 Trusts under the Investment Company Act of 1940, as amended, is required.

          6.  The Equipment Notes, when issued to and acquired by the Pass
 Through Trustee, will be valid and binding obligations of US Airways
 enforceable against US Airways in accordance with their terms and the terms
 of the Indenture, as supplemented by the Indenture Supplement, and will be
 entitled to the benefits of the Indenture, as supplemented by the Indenture
 Supplement.

          7.  The provisions of the Indenture, as supplemented by the
 Indenture Supplement, are effective to create, in favor of the Indenture
 Trustee to secure the Secured Obligations, a valid security interest in US
 Airways' rights in that portion of the collateral described therein which
 is subject to Article 9 of the New York UCC (the "UCC Collateral").

          8.  The New York Financing Statement is in appropriate form for
 filing in the New York Filing Office.  To the extent that the New York UCC
 governs the perfection of a security interest in US Airways' rights in the
 UCC Collateral, as to which we express no opinion, the security interest in
 favor of the Indenture Trustee in the UCC Collateral described in the New
 York Financing Statement will be perfected upon filing of the New York
 Financing Statement in the New York Filing Office.

          8.  Based solely on our review of the Virginia UCC as published
 in the CCH Secured Transaction Guide (without consideration of case law
 decided thereunder), we are of the opinion that (i) the Virginia Financing
 Statements are in appropriate form for filing in the Virginia Filing
 Offices and (ii) to the extent that the Virginia UCC governs the perfection
 of a security interest in US Airways' rights in the UCC Collateral, as to
 which we express no opinion, the security interest in favor of the
 Indenture Trustee in the UCC Collateral described in the Virginia Financing
 Statements will be perfected upon filing of the Virginia Financing
 Statements in the Virginia Filing Offices.

          Our opinions in paragraphs 6, 7 and 8 with respect to the security
 interest of the Indenture Trustee are subject to the following
 qualifications:

          (a)  We have assumed the US Airways owns, or with respect to
 after-acquired property will own, the UCC Collateral, and we express no
 opinion as to the nature or extent of US Airways' rights in or title to any
 of the UCC Collateral and we note that with respect to after-acquired
 property, the security interest will not attach until US Airways acquires
 ownership thereof.

          (b)  Our opinion with respect to the security interest of the
 Indenture Trustee is limited to Article 9 of the Applicable UCC, and such
 opinion does not address (i) laws of jurisdictions other than New York or
 Virginia, and of New York or Virginia except for Article 9 of the
 Applicable UCC, (ii) collateral of a type not subject to Article 9 of the
 Applicable UCC, and (iii) what law governs perfection or priority of the
 security interests granted in the collateral covered by this opinion.

          (c)  We call your attention that under the Applicable UCC, events
 occurring subsequent to the date hereof may affect any security interest
 subject to the Applicable UCC including, but not limited to, factors of the
 type identified in Section 9-306 with respect to proceeds; Section 9-103
 with respect to changes in the location of the collateral and the location
 of a debtor; and Sections 9-307, 9-308 and 9-309 with respect to subsequent
 purchasers of the collateral.  In addition, actions taken by a secured
 party (e.g., releasing or assigning the security interest, delivering
 possession of the collateral to a debtor or another person and voluntarily
 subordinating a security interest) may affect any security interest subject
 to the Applicable UCC.

          (d)  We express no opinion with respect to the priority of the
 security interest of the Indenture Trustee.

          (e)  We call to your attention that with respect to any goods
 which is an accession to, or commingled or processed with other goods, the
 security interest of the Indenture Trustee may be limited by Section 9-314
 or 9-315 of the New York UCC.

          (f)  In the case of any instrument, chattel paper, account or
 general intangible which is itself secured by other property, we express no
 opinion with respect to the Indenture Trustee's rights in and to such
 underlying property.

          (g)  In the case of chattel paper, accounts or general
 intangibles, we call to your attention that the security interest of the
 Indenture Trustee for the benefit of the Pass Through Trustee may be
 subject to the rights of account debtors, claims and defenses of account
 debtors and the terms of agreements with account debtors.

          (h)  In the case of goods, we express no opinion regarding the
 security interest of the Indenture Trustee for the benefit of the Pass
 Through Trustee in any goods which are subject to a certificate of title or
 a document of title.

          (i)  We express no opinion regarding the security interest of the
 Indenture Trustee for the benefit of the Pass Through Trustee in any items
 which are subject to a statute, regulation or treaty of the United States
 of America which provides for a national or international registration or a
 national or international certificate of title for the perfection of a
 security interest therein or which specifies a place of filing different
 from the place specified in the Applicable UCC for filing to perfect such
 security interest.

          (j)  We express no opinion regarding the security interest of the
 Indenture Trustee for the benefit of the Pass Through Trustee in any of the
 UCC Collateral consisting of claims against any government or governmental
 agency (including without limitation the United States of America or any
 state thereof or any agency or department of the United States of America
 or any state thereof).

          (k)  We have assumed that US Airways maintains a place of business
 in more than one county in the State of New York.

          (l)  we express no opinion as to collateral of a type perfected by
 means other than the filing of a financing statement under the Applicable
 UCC.

          (m)  We express no opinion with respect to collateral consisting
 of goods which are or are to become fixtures, equipment used in farming
 operations, or farm products, or accounts or general intangibles arising
 from or relating to the sale of farm products by a farmer, consumer goods,
 crops growing or to be grown, timber to be cut or minerals or the like
 (including oil and gas), or accounts subject to subsection 5 of Section 9-
 103 of the Applicable UCC.

          (n)  We call to your attention that we have not considered the
 effect of any tax laws or other similar laws of the Commonwealth of
 Virginia which may require the payment of a tax or fee in connection with
 the filing of the Virginia Financing Statements and we express no opinion
 regarding any tax or fee payable in connection with the filing of the
 Virginia Financing Statement (including, without limitation, the existence
 or calculation of any such tax or fee).

          (o)  We have assumed that either the Company maintains a place of
 business in more than one county in the Commonwealth of Virginia or that
 the Company's only place of business in the Commonwealth of Virginia is and
 will be located at 2345 Crystal Drive, Arlington, VA  22227.

          9.  The Indenture Trustee acting in behalf of the holders of the
 Equipment Notes will be entitled to the benefits of Section 1110 of the
 Bankruptcy Code with respect to the Aircraft if US Airways is a debtor in a
 case under Chapter 11 of the Bankruptcy Code.

          10.  [US Airways, as lessor under the Shuttle Lease, will be
 entitled to the benefits of Section 1110 of the Bankruptcy Code with
 respect to the Aircraft if Shuttle is a debtor in a case under Chapter 11
 of the Bankruptcy Code.](2)
 -------------
 (2)   For Aircraft with Shuttle, Inc. Lease only.

          With respect to our opinion[s] in paragraph[s] 9 [and 10], we note
 that a 1998 decision, Western Pacific Airlines, Inc. v. GATX (In re Western
 Pacific Airlines, Inc.), 219 B.R. 305, on rehearing, 221 B.R. 1 (D. Colo.
 1998), appeal dismissed as moot, vacatur denied, Boullioun Aircraft Holding
 Co., Inc. v. Smith Management (In re Western Pacific Airlines, Inc.), 1999
 WL 459469 (10th Cir. July 7, 1999), ruled that Section 1110 does not apply
 in a case after the trustee timely makes the agreement specified in Section
 1110(a)(1)(A) and timely cures defaults outstanding as of the date of the
 Chapter 11 petition or that occur during the first sixty days of the case,
 with the result, among others, that the ability of an Indenture Trustee to
 exercise remedies based on a default that occurs after the first sixty days
 of the Chapter 11 case would be subject to the automatic stay.  We believe
 that this decision construes Section 1110 in a manner that is inconsistent
 with both the language of Section 1110 and the legislative history
 explaining the purpose and operation of Section 1110.  Accordingly, we
 believe that the decision is an incorrect interpretation of Section 1110.

          In addition, with respect to our opinion[s] in paragraph[s] 9 [and
 10], we have, with your consent, relied on the US Airways Opinion (as
 defined below) to the effect that [each of] US Airways [and Shuttle] is a
 "citizen of the United States," as defined in Section 40102 of Title 49 of
 the United States Code, and [each of] US Airways [and Shuttle] hold an "air
 carrier operating certificate" issued by the Secretary of Transportation
 (or by the Administrator of the FAA acting under authority delegated by the
 Secretary of Transportation) pursuant to Section 44705 (in Chapter 447) of
 the Transportation Code for aircraft capable of carrying ten or more
 individuals or 6,000 pounds or more of cargo.  We have assumed that where
 the Indenture Trustee is acting as secured party, the security interest of
 the Indenture Trustee in the Aircraft is perfected.

          Our opinions are subject to the following assumptions and
 qualifications:

          (a)  enforcement of the Transaction Documents may be limited by
 applicable bankruptcy, insolvency, reorganization, moratorium or other
 similar laws affecting creditors' rights generally and by general
 principles of equity (regardless of whether enforcement is sought in equity
 or at law);

          (b)  certain of the remedial provisions with respect to the
 security including waivers with respect to the exercise of remedies against
 the Indenture Estate contained in the Indenture, as supplemented by the
 Indenture Supplement, may be unenforceable in whole or in part, but the
 inclusion of such provisions does not affect the validity of each of the
 Indenture, as supplemented by the Indenture Supplement, taken as a whole,
 and the Indenture, as supplemented by the Indenture Supplement, taken as a
 whole, together with applicable law, contains adequate provisions for the
 practical realization of the security thereof;

          (c)  we express no opinion as to the effect on the opinions
 expressed herein of (i) the compliance or non-compliance of any party
 (without in any way limiting other qualifications and assumptions made
 herein, other than US Airways) to the Transaction Documents with any state,
 federal or other laws or regulations applicable to it or (ii) the legal or
 regulatory status or the nature of the business of any such party;

          (d)  we express no opinion as to the enforceability of any rights
 to contribution or indemnification provided for in the Transaction
 Documents to the extent any such rights are violative of the public policy
 (including, without limitation, the public policy underlying any federal or
 state securities law, rule or regulation);

          (e)  we express no opinion as to any provision of any Transaction
 Document that provides a penalty or to the extent that it provides for an
 absolute and unconditional obligation to perform such Transaction Document
 even though such Transaction Document is invalid or terminated or such
 performance would be illegal; and

          (f)  with respect to our opinion that the New York choice of law
 provision in the Transaction Documents which are expressly governed by New
 York law is enforceable, we rely upon, among other things, the Act of July
 19, 1984, Ch. 421, 1984 McKinney's Sess. Laws of N.Y. 1406, (codified at
 N.Y. Gen. Oblig. Law sections 5-1401, 5-1402 (McKinney 1989) and N.Y. CPLR
 327(b) (McKinney 1990) (the "Act"), and our opinion is subject to the
 qualifications that such enforceability (i) may be limited by public policy
 considerations of any jurisdiction, other than the courts of the State of
 New York, in which enforcement of such provisions, or of a judgement upon
 an agreement containing such provisions, is sought, and (ii) as specified
 in the Act, does not apply to the extent provided to the contrary in
 subsection two of Section 1-105 of the Uniform Commercial Code for the
 State of New York.

          In rendering the foregoing opinions, we have assumed, with your
 consent, that:

          (a)  each of the Transaction Documents constitutes the legal,
 valid and binding obligation of each party thereto (other than US Airways
 and, in the case of the Indenture, the Indenture Trustee) enforceable
 against each such party (other than US Airways and, in the case of the
 Indenture, the Indenture Trustee) in accordance with its terms;

          (b)  each of (i) State Street Bank and Trust Company of
 Connecticut, National Association and (ii) US Airways is duly organized and
 validly existing in good standing under the laws of the jurisdiction of its
 organization;

          (c)  each of (i) State Street Bank and Trust Company of
 Connecticut, National Association, individually and as Indenture Trustee,
 Subordination Agent and Pass Through Trustee, (ii) US Airways has full
 power, authority and legal right to enter into and perform its respective
 obligations under, and consummate the transactions contemplated by, each of
 the Transaction Documents to which it is a party;

          (d)  each of (i) State Street Bank and Trust Company of
 Connecticut, National Association, individually and as Indenture Trustee,
 Subordination Agent and Pass Through Trustee, and (ii) US Airways has duly
 authorized, executed and delivered each of the Transaction Documents to
 which it is a party;

          (e)  the execution, delivery and performance of the Transaction
 Documents by each of the parties thereto and the consummation of the
 transactions contemplated thereby does not and will not conflict with,
 contravene, violate or constitute a default under (i) the respective
 certificate of incorporation, by-laws or other organizational documents of
 any such party, (ii) any indenture, mortgage, lease, agreement or other
 instrument to which any such party is a party or by which it or any of its
 property may be bound or subject, (iii) any law, rule or regulation of any
 jurisdiction (provided that we make no such assumption with respect to
 Applicable Laws of the State of New York and Applicable Laws of the United
 States of America insofar as such Applicable Laws apply to US Airways, as
 to which we express our opinion in paragraph 2 herein) or (iv) any judicial
 or administrative order or decree of any governmental authority; and

          (f)  except for (i) the due and timely filing and, where
 appropriate, recording of the Indenture and the Indenture Supplement
 covering the Aircraft attached as an exhibit pursuant to the Transportation
 Code, (ii) the registration of the issuance and sale of the Pass Through
 Certificates under the Securities Act, (iii) compliance with the securities
 law of each applicable state and (iv) the filing of appropriate UCC
 financing statements, no consent, license, permit or approval of, or giving
 of notice to, or registration with, or taking of any action in respect of,
 any governmental authority of any jurisdiction is required in connection
 with (X) the execution, delivery and performance by any party to any
 Transaction Document of the respective Transaction Documents to which it is
 a party, (Y) the consummation of the transactions contemplated thereby or
 (Z) the legality, validity or enforceability of the Transaction Documents
 with respect to any party to any Transaction Document (provided that we
 make no such assumption with respect to those required by Applicable Laws
 as such Applicable Laws apply to US Airways).

          With respect to US Airways, we understand that you are separately
 receiving an opinion with respect to certain matters set forth above from
 Howard L. Wu, Esq., Associate General Counsel to US Airways (the "US
 Airways Opinion").  With respect to Transportation Code matters, we

 To Each Person Listed
 on Schedule I Hereto

      Re:  US Airways, Inc. N__U__

 Ladies and Gentlemen:

      I am the ____________________ of US Airways, Inc., a Delaware
 corporation ("US Airways"), and am familiar with the transactions
 contemplated by the Participation Agreement (N___U_), dated as of _________
 __, ____ (the "Participation Agreement"), by and between US Airways, as
 Owner and State Street Bank and Trust Company of Connecticut, National
 Association, a national banking association, not in its individual capacity
 except as otherwise provided therein but solely as Pass Through Trustee,
 Indenture Trustee and Subordination Agent.  Capitalized terms not otherwise
 defined herein have the meanings assigned thereto in Annex A to the
 Participation Agreement.

      This opinion is being delivered pursuant to Section 4(a)(ix) of the
 Participation Agreement.

      In my examination, I have assumed the genuineness of all signatures
 (other than the signatures made on behalf of US Airways), including
 endorsements, the legal capacity of natural persons, the authenticity of
 all documents submitted to me as originals, the conformity to original
 documents of all copies submitted to me as telefacsimile, certified or
 photostatic copies, and the authenticity of the originals of such copies.
 As to any facts material to this opinion, I have relied solely upon
 statements, representations and warranties of US Airways, the Indenture
 Trustee, the Subordination Agent, the Pass Through Trustee and their
 respective officers and representatives, and others in the Operative
 Documents and of public officials, and I have made no independent
 investigation or inquiry with respect to such factual matters.

      In rendering the opinions set forth herein, I have examined and relied
 on executed originals or copies of the following:

      (a)  the Participation Agreement;

      (b)  the Purchase Agreement Assignment;

      (c)  the Indenture;

      (d)  the Indenture Supplement;

      (e)  the Warranty Bill of Sale;

      (f)  the Equipment Notes;

      (g)  the Pass Through Trust Agreement;

      (h)   each of the Pass Through Trust Agreement Supplements;

      (i)   certified copies of the Certificate of Incorporation and By-laws
 of  US Airways;

      (j)  certified copies of certain resolutions of the Board of Directors
 of US Airways adopted on May 18, 1999;

      (k)   a certificate of good standing from the Secretary of State of
 the State of Delaware as to the good standing of US Airways in such
 jurisdiction [and a certificate of good standing from the Secretary of
 State of the State of Delaware as the good standing of Shuttle, Inc. in
 such jurisdiction](1); and

      (l) such other documents as I have deemed necessary or appropriate as
 a basis for the opinions set forth below.

 -------------------
    (1)     For Shuttle, Inc. transactions only.


      Based on the foregoing and subject to the limitations, qualifications,
 exceptions and assumptions set forth herein, it is my opinion that:

      1.      US Airways is a corporation duly incorporated, validly
 existing and in good standing under the laws of the State of Delaware, is a
 "citizen of the United States" within the meaning of Section 40102(a)(15)
 of the Transportation Code, and has or had, on the date of execution
 thereof, the corporate power and authority to carry on its business as
 currently conducted and to enter into and perform its obligations under
 each of the Operative Documents to which it is a party.  US Airways is duly
 qualified to do business and is in good standing in the Commonwealth of
 Virginia and each other state of the United States in which its operations
 or the nature of its business requires US Airways to so qualify, except
 where the failure to so qualify would not have a material adverse effect on
 US Airways or its business.

      2.      US Airways possesses all necessary certificates, franchises,
 licenses, permits, rights and concessions and consents which are material
 to the operation of the routes flown by it and the conduct of its business
 and operations as currently conducted, and each such certificate,
 franchise, license, permit, right and concession and consent is in full
 force and effect, except where any failure would not have a material
 adverse effect on US Airways or its business.

      3.      Each of the Operative Documents to which US Airways is a party
 has or had, on the date of execution thereof, been duly authorized,
 executed and delivered by US Airways.

      4.      Neither the execution and delivery by US Airways of any of the
 Operative Documents to which US Airways is a party, nor the consummation of
 any of the transactions by US Airways contemplated thereby, nor the
 performance of the obligations thereunder by US Airways, did at the time of
 execution and delivery, or does presently (a) require any stockholder
 approval or violate the Certificate of Incorporation or By-laws of US
 Airways or (b) conflict with or contravene the provisions of, or constitute
 a default under, or result in the creation of any Lien (other than any
 Permitted Lien) upon the property of US Airways under any law, governmental
 rule or regulation, or the Certificate of Incorporation or By-laws of US
 Airways or any order, writ, injunction or decree of any court or
 governmental authority against US Airways or by which any of its properties
 may be bound or any material indenture, mortgage, contract or other
 agreement known to me to which US Airways is a party or by which it may be
 bound, or require the approval or consent of any trustee or the holders of
 any indebtedness or material obligations of US Airways.

      5.      Neither the execution and delivery by US Airways of any of the
 Operative Documents to which it is a party, nor the consummation of any
 transactions by US Airways contemplated thereby, nor the performance of the
 obligations thereunder by US Airways, did or does, as the case may be, (a)
 require the consent or approval of, the giving of notice to, or (except as
 described or contemplated in the Operative Documents, all of which were or
 are required to be performed on or prior to the Delivery Date and which
 were or shall have been accomplished on or prior to the Delivery Date) the
 registration with, or the taking of any other action in respect of, the
 FAA, the Securities and Exchange Commission or any other authority or
 agency of the federal government or of the State of Delaware other than (i)
 the registration of the issuance and sale of the Pass Through Certificates
 under the Securities Act, (ii) compliance with the securities laws of each
 applicable state and (iii) the filings and, where appropriate, recording,
 pursuant to the Transportation Code, of the Indenture (with the Indenture
 Supplement covering the Aircraft attached as an exhibit) or (b) contravene
 any judgment or order applicable to or binding on US Airways or any law or
 governmental rule or regulation of the United States or of the State of
 Delaware.

      6.      There is no pending or, to my knowledge, threatened action or
 proceeding before any court or administrative agency which individually (or
 in the aggregate in the case of any group of related lawsuits) (i) is
 expected to have a material adverse effect on (A) the financial condition
 of US Airways except for the matters described under "Legal Proceedings" in
 US Airways' Annual Report on Form 10-K for the fiscal year ended December
 31, ____ and US Airways' Quarterly Report on Form 10-Q for the quarter
 ended [March 31, ____, June 30, ____ and September 30, ____,] respectively,
 as to all of which I can express no opinion at this time concerning US
 Airways' liability (if any) or the effect of any adverse determination upon
 the business, condition (financial or otherwise) or operations of US
 Airways, or (B) the ability of US Airways to perform its obligations under
 the Operative Documents, or (ii) involves the Aircraft.

      7.     US Airways is a duly certificated "air carrier" within the
 meaning of the Transportation Code, and a holder of a certificate under
 Section 41102(a) of the Transportation Code.  US Airways is the holder of
 an "air carrier operating certificate"  under Section 44705 of the
 Transportation Code for aircraft capable of carrying ten (10) or more
 individuals or 6,000 pounds or more of cargo, and such certificate is in
 full force and effect.

      8.     US Airways is not, and is not directly or indirectly controlled
 by or acting on behalf of any Person which is, an "investment company"
 within the meaning of the Investment Company Act of 1940, as amended.

      9.      [Shuttle, Inc. is a corporation duly incorporated, validly
 existing and in good standing under the laws of the State of Delaware and
 is a "citizen of the United States" within the meaning of Section
 40102(a)(15) of the Transportation Code.](2)

      10.     [Shuttle, Inc. is a duly certificated "air carrier" within the
 meaning of the Transportation Code, and a holder of a certificate under
 Section 41102(a) of the Transportation Code.  Shuttle, Inc. is the holder
 of an "air carrier operating certificate"  under Section 44705 of the
 Transportation Code for aircraft capable of carrying ten (10) or more
 individuals or 6,000 pounds or more of cargo, and such certificate is in
 full force and effect.](3)

  (2)    For Shuttle, Inc. transactions only.

  (3)    For Shuttle, Inc. transactions only.


      I do not express any opinion as to matters governed by any law other
 than the federal laws of the United States of America and the corporation
 law of the State of Delaware.

      This opinion is delivered to you solely for your use in connection
 with the transaction described herein, and may not be used for any other
 purpose, and may not be relied upon by any other person, without my prior
 written consent.

            Assignment as acknowledged and accepted by US Airways Group,

            between the Company (as owner) and the Indenture Trustee (the

            PLEDGE" and in the French language as the "ACTE DE NANTISSEMENT
            DE CREANCES" (the latter being a correct translation of the
            former) each dated [       ] and made between the Company (as
            pledgor) and the Indenture Trustee (as pledgee) collectively
            referred to herein as the "ACTE DE NANTISSEMENT",

      the First Purchase Agreement and the Second Purchase Agreement
      Assignment are together referred to herein as the "ASSIGNMENTS", the
      First Consent and the Second Consents are together referred to herein
      as the "CONSENTS" and the documents referred to in (i) to (vii) above
      are hereinafter referred to collectively as the "DOCUMENTS".

3.    In considering the above, we have assumed:

      (i)   that the Documents have been duly executed by the parties
            thereto (other than Airbus and AVSA);

      (ii)  the genuineness of all signatures;

      (iii) the completeness and conformity to the originals of all
            documents supplied to us as copies or as facsimiles;

      (iv)  that the Documents expressed to be governed by New York law
            constitute the legal, valid and binding obligations of the
            parties thereto under New York law.

4.    Having considered the Documents we are of the opinion, subject to the
      qualifications and reservations set out in paragraph 5 below, that:

      (i)   Airbus is a groupement d'interet economique duly organised and
            existing under the laws of the French Republic and has the
            power and authority to carry on its business as now conducted.
            The present members of Airbus are (i) Aerospatiale Matra S.A.,
            (ii) DaimlerChrysler Aerospace Airbus GmbH, (iii) British
            Aerospace (Operations) Ltd. and (iv) Construcciones
            Aeronauticas S.A. and each of such corporations is, without the
            need to proceed against any collateral security for the
            indebtedness of Airbus or to take any other legal action or
            process (except for service on Airbus by huissier of notice to
            perform and subsequent failure by Airbus to do so), jointly and
            severally liable with the other members for the debts of Airbus
            arising out of obligations contracted by Airbus while such
            corporation is a member of Airbus;

      (ii)  AVSA is a societe a responsabilite limitee duly established and
            existing under the laws of the French Republic and has the
            power and authority to carry on its business as now conducted;

      (iii) each of Airbus and AVSA has full power and authority to enter
            into and to execute, deliver and perform its obligations under
            the Documents to which it is a party; such obligations are
            legal, valid and binding upon them respectively, are
            enforceable in accordance with their respective terms and rank
            pari passu with the other unsecured obligations of Airbus and
            AVSA, as the case may be;

      (iv)  assuming that under New York law the Indenture Trustee would be
            entitled to take proceedings in its own name and on its own
            account to recover from the Company the full amount of all
            amounts secured by the Acte de Nantissement and subject to the
            registration and huissier requirements of paragraph 5(d) hereof
            and the observation set forth in paragraph 5(f) hereof, the
            Acte de Nantissement:

            (a) duly creates for the benefit of the Indenture Trustee the
                security interests which it purports to create and the
                Indenture Trustee is entitled to the benefits and security
                afforded thereby; and

            (b) would be effective as against Airbus, AVSA and third
                parties to perfect the pledge (nantissement) of the
                obligations of Airbus and AVSA that are the subject of the
                Acte de Nantissement;

      (v)   the choice of the laws of the State of New York to govern the
            Documents (which are expressed to be so governed) is valid
            under the laws of the French Republic, and a French court would
            uphold such choice of law in any suit on the Documents brought
            in a French court.

5.    This opinion must be read subject to the following qualifications and
      observations as to French law:

      (a)   the remedy of specific performance may not be available in a
            French court;

      (b)   in respect of payment obligations, a French court has power
            under Article 1244-1 of the French Civil Code to grant time to
            a debtor (not in excess of two years), taking into account the
            position of the debtor and the needs of the creditor;

      (c)   in order to ensure the validity as against third parties of the
            assignment made in the Assignments, it is necessary that notice
            of such assignments be served on Airbus and AVSA by huissier in
            accordance with the provisions of Article 1690 of the French
            Civil Code. [We have been instructed by the Company to assist
            in carrying out such formalities which we intend to do upon
            receipt of duly executed originals of such assignment and we
            anticipate that there will be no difficulty in accomplishing
            these formalities](2);

      (d)   in order to ensure the validity as against third parties of the
            pledge (nantissement) created by the Acte de Nantissement in
            accordance with the provisions of Article 2075 of the French
            Civil Code, it is necessary for the Acte de Nantissement to be
            registered with the French tax administration in a form duly
            translated in French by a sworn translator, involving payment
            of a stamp duty of a nominal amount. In addition, the pledge
            (nantissement) created by the Acte de Nantissement will need to
            be served on each of the obligors by huissier, in accordance
            with the provisions of Article 2075 of the French Civil Code.
            [We have been instructed by the Company to carry out such
            formalities on its behalf which we intend to do upon receipt of
            duly executed originals of the Pledge Agreement and we
            anticipate that there will be no difficulty in accomplishing
            these formalities](2);

(2)   NOTE: US AIRWAYS TO CONFIRM INSTRUCTIONS


      (e)   in the event o any proceedings being brought in a French court
            in respect of a monetary obligation expressed to be payable in
            a currency other than French Francs or euros, a French court
            would probably give judgment expressed as an order to pay, not
            such currency, but its French Franc or euro equivalent at the
            time of payment or enforcement of judgment. With respect to a
            bankruptcy, insolvency, liquidation, moratorium,
            reorganisation, reconstruction or similar proceedings, French
            law may require that all claims or debts be converted into
            French Francs or euros at an exchange rate determined by the
            court at a date related thereto, such as the date of
            commencement of a winding-up;

      (f)   pledges over non-monetary claims are unusual under French law.
            In principal, pledges over claims of this type should be
            effective against Airbus, AVSA and third parties but in the
            absence of case law, there is a lack of certainty about the
            pledge being effective;

      (g)   a determinatio or certificate as to any matter provided for in
            the Documents might be held by a French court not to be final,
            conclusive or binding, if such determination or certificate
            could be shown to have an unreasonable, incorrect or arbitrary
            basis or not to have been given or made in good faith;

      (h)   claims may become barred by effluxion of time or may be or
            become subject to defence of set-off or counterclaim;

      (i)   a French court may stay proceedings if concurrent proceedings
            are being brought elsewhere;

      (j)   we express no opinion as to whether any provision in the
            documents conferring a right of set-off or similar right would
            be effective against a liquidator or a creditor;

      (k)   the enforcemen against Airbus of any of the Documents to which
            it is a party may be limited by applicable bankruptcy,
            insolvency, arrangement, moratorium or similar laws relating to
            or affecting the enforcement of creditors' rights generally, as
            such laws are applied to Airbus. The enforcement against AVSA
            of any of the Documents to which it is a party may be limited
            to such laws, as such laws are applied to AVSA. The enforcement
            against any member of Airbus of any obligation of Airbus
            contained in the Documents may be limited to such laws, as such
            laws are applied to such member;

      (l)   our opinion as to the enforceability of the Documents relates
            only to their enforceability in France in circumstances where
            the competent French court has and accepts jurisdiction. The
            term "enforceability" refers to the legal character of the
            obligations assumed by the parties under the Documents, i.e.
            that they are of a character which French law enforces or
            recognises. It does not mean that the Documents will be
            enforced in all circumstances or in foreign jurisdictions or by
            or against third parties or that any particular remedy will be
            available; and

      (m)   article 899 of the French Tax Code provides that agreements
            evidencing an undertaking to pay a sum of money are subject to
            stamp tax (droit de timbre) of a nominal amount if made in the
            French Republic, if made in a foreign country, such agreements
            are subject to a stamp tax of a nominal amount before certain
            use thereof can be made in the French Republic (Article 897 of
            the French Tax Code). However non-payment of such stamp tax
            does not affect the legality, validity or enforceability of the
            Documents.

We are qualified as French Avocats.

No opinion is expressed herein as to laws other than the laws of the French
Republic as of the date hereof. This opinion is for your use and that of no
one else, and is limited to (i) the matters specifically mentioned herein,
and (ii) the purpose set out above.

Yours faithfully,

                      FORM OF OPINION OF FAA COUNSEL

  To the Addressees on the
  Schedule Attached Hereto

       RE:  AIRBUS INDUSTRIE MODEL A330___ AIRCRAFT WITH
            MANUFACTURER'S SERIAL NUMBER _____ AND UNITED STATES
            NATIONALITY AND REGISTRATION MARKS N_____ (THE
            "AIRCRAFT")

  Ladies and Gentlemen:

       This letter confirms that we filed with the Federal Aviation
  Administration (the "FAA") today at __:__ _.M., C._.T., the Trust
  Indenture and Security Agreement (US Airways, Inc.2000-1 Series N_____)
  dated as of _________ __, 2000 (the "Indenture") between US Airways, Inc.
  (the "Company") and ________________________ as Indenture Trustee (the
  "Indenture Trustee"), to which was attached Trust Agreement and Indenture
  Supplement No. 1 (US Airways, Inc.2000-1 Series N_____) dated ________
  __, 2000 (the "Indenture Supplement") covering the Aircraft and the
  ______________model _____________ aircraft engines with manufacturer's
  serial numbers ____________ and ______________ (the "Engines").

       Based upon our examination of the above described instruments and of
  such records of the FAA as we deemed necessary to render this opinion and
  as were made available to us by the FAA, it is our opinion that:

       (a)  the Indenture with the Indenture Supplement attached is in due
            form for recordation by and has been duly filed for recordation
            with the FAA pursuant to and in accordance with the provisions
            of Section 44107 of Title 49 of the United States Code;

       (b)  legal title to the Aircraft is vested in the Company and the
            Aircraft is duly registered in the name of the Company pursuant
            to and in accordance with the provisions of Sections 44102 and
            44103 of Title 49 of the United States Code;

       (c)  the Aircraft and the Engines are free and clear of Liens (as
            such term is defined in Annex A to the Indenture) other than
            such as are created by the Indenture, as supplemented by the
            Indenture Supplement;

       (d)  the Indenture, as supplemented by the Indenture Supplement,
            creates a duly and validly perfected first priority security
            interest in favor of the Indenture Trustee in the Aircraft and
            the Engines;

       (e)  the Indenture, as supplemented by the Indenture Supplement, is
            not required to be refiled with the FAA or filed or recorded in
            any other place within the United States in order to perfect or
            maintain the perfection of the security interest created
            thereby in the Aircraft and the Engines under the applicable
            laws of any jurisdiction within the United States;

       (f)  no other registration of the Aircraft and no filings or
            recordings (other than the filings and recordings with the FAA
            which have been effected) are necessary to perfect in any
            jurisdiction within the United States the Company's title to
            the Aircraft or the security interest created by the Indenture,
            as supplemented by the Indenture Supplement, in the Aircraft
            and the Engines under the applicable laws of any jurisdiction
            within the United States; and

       (h)  no authorization, approval, consent, license or order of, or
            registration with, or giving of notice to, the FAA Aircraft
            Registry is required for the valid authorization, delivery or
            performance of the Indenture and the Indenture Supplement
            except for such authorizations, approvals, consents, licenses,
            orders, registrations and notices as have been effected.

       No opinion is herein expressed as to: (i) laws other than the
  federal laws of the United States; (ii) the validity or enforceability
  under local law of the Indenture, as supplemented by the Indenture
  Supplement; (iii) the recognition of the perfection of the security
  interest created by the Indenture, as supplemented by the Indenture
  Supplement, as against third parties in any legal proceedings outside the
  United States; and (iv) the record status of the Aircraft prior to the
  commencement of its United States registration.  Since our examination
  was limited to records maintained by the FAA Aircraft Registry, our
  opinion does not cover liens which are perfected without the filing of
  notice thereof with the FAA, such as federal tax liens, liens arising
  under Section 1368(a) of Title 29 of the United States Code and
  possessory artisans' liens, and was subject to the accuracy of FAA
  personnel in the filing, indexing and recording of instruments filed with
  the FAA and in the search for encumbrance cross-reference index cards for
  the Engines.  [THIS OPINION IS BEING DELIVERED AT THE REQUEST OF US
  AIRWAYS, INC.]

                                        Very truly yours,

      RE:  US Airways, Inc./Secured Financing of One Airbus [A320]
           [A330-300] Aircraft [N _____ US] -- Indenture Trustee,
           Owned Aircraft

 Ladies and Gentlemen:

      We have acted as special counsel for State Street Bank and Trust
 Company of Connecticut, National Association, in its individual capacity
 ("STATE STREET") and as Indenture Trustee (the "INDENTURE TRUSTEE") under
 the Trust Indenture and Security Agreement [N ____ US] dated as of
 [________________] (the "INDENTURE") between US Airways, Inc., and State
 Street, as Indenture Trustee, in connection with the execution and delivery
 of the Participation Agreement [N ____ US] dated as of [________________]
 (the "PARTICIPATION AGREEMENT") by and among the Indenture Trustee, US
 Airways, Inc., State Street, as Pass Through Trustee (the "PASS THROUGH
 TRUSTEE"), State Street, as Subordination Agent (the "SUBORDINATION AGENT")
 and the Owner Trustee and the transactions contemplated thereby.
 Capitalized terms not otherwise defined herein shall have the meanings
 specified in the Lease and Annex A of the Participation Agreement.  This
 opinion is being delivered at the request of State Street and pursuant to
 Section 4( )(  ) of the Participation Agreement.

      Our representation of State Street and the Indenture Trustee has been
 as special counsel for the limited purposes stated above.  As to all
 matters of fact (including factual conclusions and characterizations and
 descriptions of purpose, intention or other state of mind), we have relied,
 with your permission, entirely upon (i) the representations and warranties
 of the parties set forth in the Operative Documents and (ii) certificates
 delivered to us by the management of State Street and have assumed, without
 independent inquiry, the accuracy of those representations, warranties and
 certificates.

      We have examined the Participation Agreement and the Indenture (the
 "OPERATIVE DOCUMENTS"), the Certificate of the Comptroller of the Currency
 relating to State Street and originals, or copies certified or otherwise
 identified to our satisfaction, of such other records, documents,
 certificates, or other instruments as we have deemed necessary or advisable
 for the purposes of this opinion.  For purposes of our opinion rendered in
 paragraph 1 below, with respect to the authority of State Street to operate
 as a national banking association and exercise trust powers, our opinion
 relies upon and is limited by such Certificate of the Comptroller of the
 Currency.

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

      When an opinion set forth below is given to the best of our knowledge,
 or to our knowledge, or with reference to matters of which we are aware or
 which are known to us, or with another similar qualification, the relevant
 knowledge or awareness is limited to the actual knowledge or awareness of
 the individual lawyer in the firm that signed this opinion, the individual
 lawyers in the firm who have participated directly in the specific
 transactions to which this opinion relates and the partner of the firm
 responsible for State Street corporate trust matters, and without any
 special or additional investigation undertaken for the purposes of this
 opinion.

      Subject to the limitation set forth below, we have made such
 examination of law as we have deemed necessary for the purposes of this
 opinion.  The opinions set forth below are limited solely to the internal
 substantive laws of the State of Connecticut as applied by courts located
 in Connecticut and the federal laws of the United States.  No opinion is
 given herein as to the choice of law or internal substantive rules of law
 that any court or other tribunal may apply to the transactions contemplated
 by the Operative Documents.  No opinion is expressed herein as to the
 application or effect of federal securities laws or as to the securities or
 so-called "Blue Sky" laws of any state or other jurisdiction.  In addition,
 no opinion is expressed as to matters governed by any law, statute, rule or
 regulation of the United States relating to the acquisition, ownership,
 registration, use, operation, maintenance, repair, replacement or sale of
 or the nature of the Aircraft.

      To the extent to which this opinion deals with matters governed by or
 relating to the laws of the State of New York, or other jurisdiction other
 than the State of Connecticut, by which the Operative Documents are stated
 to be governed, we have assumed, with your permission that the Operative
 Documents are governed by the internal substantive laws of the State of
 Connecticut.

      Our opinion is further subject to the following exceptions,
 qualifications and assumptions:

            1. We have assumed without any independent investigation that
      (i) each party to the Operative Documents, other than State Street,
      in its individual capacity or as Indenture Trustee, as applicable, at
      all times relevant thereto, is validly existing and in good standing
      under the laws of the jurisdiction in which it is organized, and is
      qualified to do business and in good standing under the laws of each
      jurisdiction where such qualification is required generally or
      necessary in order for such party to enforce its rights under such
      Operative Documents, and (ii) each party to the Operative Documents,
      at all times relevant thereto, had and has the full power, authority
      and legal right under its certificate of incorporation, partnership
      agreement, bylaws, and other governing organizational documents, and
      the applicable corporate, partnership, or other enterprise
      legislation and other applicable laws, as the case may be (other than
      State Street and the Indenture Trustee with respect to the laws of
      the United States of America and the internal substantive laws of the
      State of the Connecticut, but only in each case to the limited extent
      the same may be applicable to State Street or the Indenture Trustee,
      and relevant to our opinions expressed below) to execute, and to
      perform its obligations under, the Operative Documents, and (iii)
      each party to the Operative Documents (other than State Street or the
      Indenture Trustee, as applicable) has duly executed and delivered
      each of such agreements and instruments to which it is a party and
      that (other than with respect to State Street and the Indenture
      Trustee, as applicable) the execution and delivery of such agreements
      and instruments and the transactions contemplated thereby have been
      duly authorized by proper corporate or other organizational
      proceedings as to such party.

            2. We have assumed without any independent investigation (i)
      that each of the Operative Documents is a valid, binding and
      enforceable obligation of each party thereto other than State Street
      or the Indenture Trustee, as applicable, and (ii) that each of the
      Operative Documents is a valid, binding and enforceable obligation of
      State Street or the Indenture Trustee, as applicable, to the extent
      that laws other than those of the State of Connecticut are relevant
      thereto (other than the laws of the United States of America, but
      only to the limited extent the same may be applicable to State Street
      or the Indenture Trustee, as applicable, and relevant to our opinions
      expressed below).

            3. The enforcement of any obligations of State Street or the
      Indenture Trustee, as applicable, under any of the Operative
      Documents may be limited by the receivership, conservatorship and
      supervisory powers of bank regulatory agencies generally, as well as
      by bankruptcy, insolvency, reorganization, moratorium, marshaling or
      other laws and rules of law affecting the enforcement generally of
      creditors' rights and remedies (including such as may deny giving
      effect to waivers of debtors' or guarantors' rights); and we express
      no opinion as to the status under any fraudulent conveyance laws or
      fraudulent transfer laws of any of the obligations of State Street or
      the Indenture Trustee, as applicable, under any of the Operative
      Documents.

            4. We express no opinion as the availability of any specific or
      equitable relief of any kind.

            5. The enforcement of any of your rights may in all cases be
      subject to an implied duty of good faith and fair dealing and to
      general principles of equity (regardless of whether such
      enforceability is considered in a proceeding at law or in equity)
      and, as to any of your rights to collateral security, will be subject
      to a duty to act in a commercially reasonable manner.

            6. We express no opinion as to the enforceability of any
      particular provision of any of the Operative Documents relating to
      (i) waivers of rights to object to jurisdiction or venue, or consents
      to jurisdiction or venue, (ii) waivers of rights to (or methods of)
      service of process, or rights to trial by jury, or other rights or
      benefits bestowed by operation of law, (iii) waivers of any
      applicable defenses, setoffs, recoupments, or counterclaims, (iv) the
      grant of powers of attorney to any person or entity, (v) exculpation
      or exoneration clauses, indemnity clauses, and clauses relating to
      releases or waivers of unmatured claims or rights, (vi) the
      imposition or collection of interest on overdue interest or providing
      for a penalty rate of interest or late charges on overdue or
      defaulted obligations, or the payment of any premium, liquidated
      damages, or other amount which may be held by any court to be a
      "penalty" or a "forfeiture," or (vii) so-called "usury savings
      clauses" purporting to specify methods of (or otherwise assure)
      compliance with usury laws or other similar laws of any jurisdiction.

            7. We express no opinion as to the effect of events occurring,
      circumstances arising, or changes of law becoming effective or
      occurring, after the date hereof on the matters addressed in this
      opinion letter, and we assume no responsibility to inform you of
      additional or changed facts, or changes in law, of which we may
      become aware.

            8. No opinion is given herein as to the effect of usury laws
      (or other similar laws) of any jurisdiction with respect to the
      Operative Documents.

      This opinion is rendered solely for the benefit of those institutions
 listed on Schedule A hereto and their successors and assigns in connection
 with the transactions contemplated by the Operative Documents and may not
 be used or relied upon by any other person or for any other purpose.

      Based upon the foregoing and subject to the limitations and
 qualifications set forth herein, we are of the opinion that:

      1.   State Street is a national banking association, validly formed
 and authorized to operate as a national banking association under the laws
 of the United States of America and, in its individual capacity or as
 Indenture Trustee, as the case may be, has the requisite corporate and
 trust power and authority to execute, deliver and perform its obligations
 under the Operative Documents and in its capacity as Indenture Trustee, to
 authenticate the Equipment Notes issued on the date hereof.

      2.   State Street, in its individual capacity or as Indenture Trustee,
 as the case may be, has duly authorized the Operative Documents by all
 necessary corporate or trust action and has duly executed and delivered the
 Operative Documents, and the Operative Documents constitute valid and
 binding obligations of State Street, in its individual capacity or as
 Indenture Trustee, as the case may be, enforceable against State Street, in
 its individual capacity or as Indenture Trustee, as the case may be, in
 accordance with their respective terms.

      3.   The Equipment Notes issued as of the date hereof have been duly
 authenticated and delivered by State Street as Indenture Trustee pursuant
 to the terms of the Indenture.

      4.   The authorization, execution, delivery and performance by State
 Street, in its individual capacity or as Indenture Trustee, as the case may
 be, of the Operative Documents and the consummation of the transactions
 therein contemplated and compliance with the terms thereof do not and will
 not result in the violation of the provisions of the charter documents or
 by-laws of State Street and, to the best of our knowledge, do not conflict
 with, or result in a breach of any terms or provisions of, or constitute a
 default under, or result in the creation or the imposition of any lien,
 charge or encumbrance upon any property or assets of State Street under any
 indenture, mortgage or other agreement or instrument, in each case known to
 us, to which State Street is a party or by which it is bound, or violates
 any applicable Connecticut or federal law, rule or regulation governing
 State Street's banking or trust powers, or, to the best of our knowledge,
 of any judgment, order or decree, in each case known to us, applicable to
 State Street of any court, regulatory body, administrative agency,
 government or governmental body having jurisdiction over State Street.

      5.   No authorization, approval, consent, license or order of, giving
 of notice to, registration with, or taking of any other action in respect
 of, any federal or state governmental authority or agency pursuant to any
 federal or Connecticut law governing the banking or trust powers of State
 Street is required for the authorization, execution, delivery and
 performance by State Street, in its individual capacity or as Indenture
 Trustee, as the case may be, of the Operative Documents or the consummation
 of any of the transactions by State Street, in its individual capacity or
 as Indenture Trustee, as the case may be, contemplated thereby (except as
 shall have been duly obtained, given or taken); and such authorization,
 execution, delivery, performance, consummation and issuance do not conflict
 with or result in a breach of the provisions of any such law.

      6.   There are no taxes, fees or other governmental charges payable
 under the laws of the State of Connecticut or any political subdivision of
 such State in connection with the execution and delivery by State Street,
 in its individual capacity or as Indenture Trustee, as the case may be, of
 the Operative Documents (except for taxes on any fees payable to State
 Street in its individual capacity) which are imposed solely because State
 Street has its principal place of business in Connecticut or performs its
 administrative duties under the Operative Documents in Connecticut.

      7.   To our knowledge, but without having investigated any
 governmental records or court dockets, and without having made any other
 independent investigation, there are no proceedings pending or overtly
 threatened in writing against or affecting State Street in any court or
 before any governmental authority, agency, arbitration board or tribunal
 which, if adversely determined, individually or in the aggregate, could
 reasonably be expected to affect materially and adversely the trust related
 to the Indenture or affect the right, power and authority of State Street,
 in its individual capacity or as Indenture Trustee, as the case may be, to
 enter into or perform its obligations under the Operative Documents.


                                        Very truly yours,


                                        BINGHAM DANA LLP

                               ____________________, ____

 TO THE PARTIES SET FORTH
   IN SCHEDULE A HERETO

      RE:  US Airways, Inc./Secured Financing of One Airbus [A320]
           [A330-300] Aircraft [N _________ US] -- Pass Through
           Trust, Owned Aircraft

 Ladies and Gentlemen:

      We have acted as special counsel for State Street Bank and Trust
 Company of Connecticut, National Association, in its individual capacity
 ("STATE STREET") and as Pass Through Trustee (the "PASS THROUGH TRUSTEE")
 under the Pass Through Trust Agreement dated as of July 30, 1999, among US
 Airways Group, Inc., US Airways, Inc. and State Street, as supplemented by
 Trust Supplement No. [2000-1G], and Trust Supplement No. [2000-1C] each
 dated as of [                      ] and each among US Airways, Inc. and
 State Street (collectively, the "PASS THROUGH TRUSTS" and, individually, a
 "PASS THROUGH TRUST") in connection with the execution and delivery of the
 Participation Agreement [N              ] dated as of [
                ] (the "PARTICIPATION AGREEMENT") by and among State Street,
 as Indenture Trustee, US Airways, Inc., State Street, as Pass Through
 Trustee and State Street, as Subordination Agent (the "SUBORDINATION
 AGENT") and the transactions contemplated thereby.  Capitalized terms not
 otherwise defined herein shall have the meanings specified in the Lease and
 Annex A of the Participation Agreement.  This opinion is being delivered at
 the request of State Street and pursuant to Section 4(  )(  ) of the
 Participation Agreement.

      Our representation of State Street and the Pass Through Trustee has
 been as special counsel for the limited purposes stated above.  As to all
 matters of fact (including factual conclusions and characterizations and
 descriptions of purpose, intention or other state of mind), we have relied,
 with your permission, entirely upon (i) the representations and warranties
 of the parties set forth in the Operative Documents and (ii) certificates
 delivered to us by the management of State Street and have assumed, without
 independent inquiry, the accuracy of those representations, warranties and
 certificates.

      We have examined the Participation Agreement, the Liquidity Facility
 for each of the Class G and Class C Trusts, the Policy Provider Agreement,
 the Policy, the Intercreditor Agreement, the Note Purchase Agreement, the
 Escrow and Paying Agent Agreement for each of the Class G and Class C
 Trusts each dated as of ______________ __, ____ and each among First
 Security Bank, National Association, as Escrow Agent, the underwriters
 named therein, State Street, as Pass Through Trustee and State Street, as
 Paying Agent, and each of the Pass Through Trusts (the "OPERATIVE
 DOCUMENTS"), the Certificate of the Comptroller of the Currency relating to
 State Street and originals, or copies certified or otherwise identified to
 our satisfaction, of such other records, documents, certificates, or other
 instruments as we have deemed necessary or advisable for the purposes of
 this opinion.  For purposes of our opinion rendered in paragraph 1 below,
 with respect to the authority of State Street to operate as a national
 banking association and exercise trust powers, our opinion relies upon and
 is limited by such Certificate of the Comptroller of the Currency.

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

      When an opinion set forth below is given to the best of our knowledge,
 or to our knowledge, or with reference to matters of which we are aware or
 which are known to us, or with another similar qualification, the relevant
 knowledge or awareness is limited to the actual knowledge or awareness of
 the individual lawyer in the firm that signed this opinion, the individual
 lawyers in the firm who have participated directly in the specific
 transactions to which this opinion relates and the partner of the firm
 responsible for State Street corporate trust matters, and without any
 special or additional investigation undertaken for the purposes of this
 opinion.

      Subject to the limitation set forth below, we have made such
 examination of law as we have deemed necessary for the purposes of this
 opinion.  The opinions set forth below are limited solely to the internal
 substantive laws of the State of Connecticut as applied by courts located
 in Connecticut and the federal laws of the United States.  No opinion is
 given herein as to the choice of law or internal substantive rules of law
 that any court or other tribunal may apply to the transactions contemplated
 by the Operative Documents.  No opinion is expressed herein as to the
 application or effect of federal securities laws or as to the securities or
 so-called "Blue Sky" laws of any state or other jurisdiction.  In addition,
 no opinion is expressed as to matters governed by any law, statute, rule or
 regulation of the United States relating to the acquisition, ownership,
 registration, use, operation, maintenance, repair, replacement or sale of
 or the nature of the Aircraft.

      To the extent to which this opinion deals with matters governed by or
 relating to the laws of the State of New York, or other jurisdiction other
 than the State of Connecticut, by which the Operative Documents are stated
 to be governed, we have assumed, with your permission that the Operative
 Documents are governed by the internal substantive laws of the State of
 Connecticut.

      Our opinion is further subject to the following exceptions,
 qualifications and assumptions:

            1. We have assumed without any independent investigation that
      (i) each party to the Operative Documents, other than State Street,
      in its individual capacity or as Pass Through Trustee, as applicable,
      at all times relevant thereto, is validly existing and in good
      standing under the laws of the jurisdiction in which it is organized,
      and is qualified to do business and in good standing under the laws
      of each jurisdiction where such qualification is required generally
      or necessary in order for such party to enforce its rights under such
      Operative Documents, and (ii) each party to the Operative Documents,
      at all times relevant thereto, had and has the full power, authority
      and legal right under its certificate of incorporation, partnership
      agreement, bylaws, and other governing organizational documents, and
      the applicable corporate, partnership, or other enterprise
      legislation and other applicable laws, as the case may be (other than
      State Street and the Pass Through Trustee with respect to the laws of
      the United States of America and the internal substantive laws of the
      State of Connecticut, but only in each case to the limited extent the
      same may be applicable to State Street or the Pass Through Trustee,
      and relevant to our opinions expressed below) to execute, and to
      perform its obligations under, the Operative Documents, and (iii)
      each party to the Operative Documents (other than State Street or the
      Pass Through Trustee, as applicable) has duly executed and delivered
      each of such agreements and instruments to which it is a party and
      that (other than with respect to State Street and the Pass Through
      Trustee, as applicable) the execution and delivery of such agreements
      and instruments and the transactions contemplated thereby have been
      duly authorized by proper corporate or other organizational
      proceedings as to such party.

            2. We have assumed without any independent investigation (i)
      that each of the Operative Documents is a valid, binding and
      enforceable obligation of each party thereto other than State Street
      or the Pass Through Trustee, as applicable, and (ii) that each of the
      Operative Documents is a valid, binding and enforceable obligation of
      State Street or the Pass Through Trustee, as applicable, to the
      extent that laws other than those of the State of Connecticut are
      relevant thereto (other than the laws of the United States of
      America, but only to the limited extent the same may be applicable to
      State Street or the Pass Through Trustee, as applicable, and relevant
      to our opinions expressed below).

            3. The enforcement of any obligations of State Street or the
      Pass Through Trustee, as applicable, under any of the Operative
      Documents may be limited by the receivership, conservatorship and
      supervisory powers of bank regulatory agencies generally, as well as
      by bankruptcy, insolvency, reorganization, moratorium, marshaling or
      other laws and rules of law affecting the enforcement generally of
      creditors' rights and remedies (including such as may deny giving
      effect to waivers of debtors' or guarantors' rights); and we express
      no opinion as to the status under any fraudulent conveyance laws or
      fraudulent transfer laws of any of the obligations of State Street or
      the Pass Through Trustee, as applicable, under any of the Operative
      Documents.

            4. We express no opinion as the availability of any specific or
      equitable relief of any kind.

            5. The enforcement of any of your rights may in all cases be
      subject to an implied duty of good faith and fair dealing and to
      general principles of equity (regardless of whether such
      enforceability is considered in a proceeding at law or in equity)
      and, as to any of your rights to collateral security, will be subject
      to a duty to act in a commercially reasonable manner.

            6. We express no opinion as to the enforceability of any
      particular provision of any of the Operative Documents relating to
      (i) waivers of rights to object to jurisdiction or venue, or consents
      to jurisdiction or venue, (ii) waivers of rights to (or methods of)
      service of process, or rights to trial by jury, or other rights or
      benefits bestowed by operation of law, (iii) waivers of any
      applicable defenses, setoffs, recoupments, or counterclaims, (iv) the
      grant of powers of attorney to any person or entity, (v) exculpation
      or exoneration clauses, indemnity clauses, and clauses relating to
      releases or waivers of unmatured claims or rights, (vi) the
      imposition or collection of interest on overdue interest or providing
      for a penalty rate of interest or late charges on overdue or
      defaulted obligations, or the payment of any premium, liquidated
      damages, or other amount which may be held by any court to be a
      "penalty" or a "forfeiture," or (vii) so-called "usury savings
      clauses" purporting to specify methods of (or otherwise assure)
      compliance with usury laws or other similar laws of any jurisdiction.

            7. We express no opinion as to the effect of events occurring,
      circumstances arising, or changes of law becoming effective or
      occurring, after the date hereof on the matters addressed in this
      opinion letter, and we assume no responsibility to inform you of
      additional or changed facts, or changes in law, of which we may
      become aware.

            8. No opinion is given herein as to the effect of usury laws
      (or other similar laws) of any jurisdiction with respect to the
      Operative Documents.

      In rendering the opinion set forth below in paragraph 6 as to certain
 Connecticut tax matters, we have assumed that, for federal income tax
 purposes, the trust created by the Trust Agreement will not be taxable as a
 corporation, but, rather, will be classified as a grantor trust under
 subpart E, Part I of Subchapter J of Chapter 1 of Subtitle A of the
 Internal Revenue Code of 1986, as amended or as a partnership.

      This opinion is rendered solely for the benefit of those institutions
 listed on Schedule A hereto and their successors and assigns in connection
 with the transactions contemplated by the Operative Documents and may not
 be used or relied upon by any other person or for any other purpose.

      Based upon the foregoing and subject to the limitations and
 qualifications set forth herein, we are of the opinion that:

      1.   State Street is a national banking association, validly formed
 and authorized to operate as a national banking association under the laws
 of the United States of America and, in its individual capacity or as Pass
 Through Trustee, as the case may be, has or had, as the case may be, the
 requisite corporate and trust power and authority to execute, deliver and
 perform its obligations under the Operative Documents and in its capacity
 as Pass Through Trustee, to issue and execute the Pass Through Certificates
 delivered on the Pass Through Trust Closing Date.

      2.   State Street, in its individual capacity or as Pass Through
 Trustee, as the case may be, has duly authorized by all necessary corporate
 or trust action the Operative Documents and has duly executed and delivered
 the Operative Documents, and the Operative Documents constitute valid and
 binding obligations of State Street, in its individual capacity or as Pass
 Through Trustee, as the case may be, enforceable against State Street, in
 its individual capacity or as Pass Through Trustee, as the case may be, in
 accordance with their respective terms.

      3.   The Pass Through Certificates issued and dated on the Pass
 Through Trust Closing Date have been duly issued, authenticated and
 delivered by State Street as Pass Through Trustee pursuant to the terms of
 the Operative Documents and are enforceable against the Pass Through
 Trustee and are entitled to the benefits of the applicable Pass Through
 Trusts.

      4.   The authorization, execution, delivery and performance by State
 Street, in its individual capacity or as Pass Through Trustee, as the case
 may be, of the Operative Documents and the consummation of the transactions
 therein contemplated and compliance with the terms thereof do not and will
 not result in the violation of the provisions of the charter documents or
 by-laws of State Street and, to the best of our knowledge, do not conflict
 with, or result in a breach of any terms or provisions of, or constitute a
 default under, or result in the creation or the imposition of any lien,
 charge or encumbrance upon any property or assets of State Street under any
 indenture, mortgage or other agreement or instrument, in each case known to
 us, to which State Street is a party or by which it is bound, or violates
 any applicable Connecticut or federal law, rule or regulation governing
 State Street's banking or trust powers, or, to the best of our knowledge,
 of any judgment, order or decree, in each case known to us, applicable to
 State Street of any court, regulatory body, administrative agency,
 government or governmental body having jurisdiction over State Street.

      5.   No authorization, approval, consent, license or order of, giving
 of notice to, registration with, or taking of any other action in respect
 of, any federal or state governmental authority or agency pursuant to any
 federal or Connecticut law governing the banking or trust powers of State
 Street is required for the authorization, execution, delivery and
 performance by State Street, in its individual capacity or as Pass Through
 Trustee, as the case may be, of the Operative Documents or the consummation
 of any of the transactions by State Street, in its individual capacity or
 as Pass Through Trustee, as the case may be, contemplated thereby (except
 as shall have been duly obtained, given or taken); and such authorization,
 execution, delivery, performance, consummation and issuance do not conflict
 with or result in a breach of the provisions of any such law.

      6.   There are no taxes, fees or other governmental charges payable
 under the laws of the State of Connecticut or any political subdivision of
 such State in connection with the execution and delivery by State Street,
 in its individual capacity or as Pass Through Trustee, as the case may be,
 of the Operative Documents (except for taxes on any fees payable to State
 Street in its individual capacity) or in connection with the issuance,
 execution and delivery of the Pass Through Certificates by State Street, as
 Pass Through Trustee, pursuant to the Pass Through Trusts which are imposed
 solely because State Street has its principal place of business in
 Connecticut or performs its administrative duties under the Operative
 Documents in Connecticut.  Neither State Street, in its individual capacity
 or as the Pass Through Trustee, as the case may be, the Indenture Trustee,
 the Owner Participant, the Owner Trustee, nor the trust created by the
 Trust Agreement will, as a result of the transactions contemplated thereby,
 be subject to any Taxes under the laws of the State of Connecticut or any
 political subdivision thereof (except for Taxes on any fees payable to
 State Street in its individual capacity) which are imposed because State
 Street has its principal place of business in Connecticut or performs its
 administrative duties under the Operative  Documents in Connecticut, and
 there are no Taxes under the laws of the State of Connecticut or any
 political subdivision thereof (except for Taxes on any fees payable to
 State Street in its individual capacity) upon or with respect to the
 Aircraft or any Engine or any part of any interest therein, or the
 purchase, ownership, delivery, lease, sublease, possession, presence, use,
 operation, condition, storage, maintenance, modification, alteration,
 repair, sale, return, transfer or other disposition of the Aircraft or any
 Engine which are imposed because State Street has its principal place of
 business in Connecticut or performs its administrative duties under the
 Operative Documents in Connecticut.

      7.   To our knowledge, but without having investigated any
 governmental records or court dockets, and without having made any other
 independent investigation, there are no proceedings pending or overtly
 threatened in writing against or affecting State Street in any court or
 before any governmental authority, agency, arbitration board or tribunal
 which, if adversely determined, individually or in the aggregate, could
 reasonably be expected to affect materially and adversely the trust related
 to the Indenture or affect the right, power and authority of State Street,
 in its individual capacity or as Pass Through Trustee, as the case may be,
 to enter into or perform its obligations under the Operative Documents.

                               Very truly yours,


                               BINGHAM DANA LLP

 Capitalized terms not otherwise defined herein shall have the meanings

      Our representation of State Street and the Subordination Agent has
 been as special counsel for the limited purposes stated above.  As to all
 matters of fact (including factual conclusions and characterizations and
 descriptions of purpose, intention or other state of mind), we have relied,
 with your permission, entirely upon (i) the representations and warranties
 of the parties set forth in the Operative Documents and (ii) certificates
 delivered to us by the management of State Street and have assumed, without
 independent inquiry, the accuracy of those representations, warranties and
 certificates.

      We have examined the Participation Agreement, the Note Purchase
 Agreement and the Intercreditor Agreement (the "OPERATIVE DOCUMENTS"), the
 Certificate of the Comptroller of the Currency relating to State Street and
 originals, or copies certified or otherwise identified to our satisfaction,
 of such other records, documents, certificates, or other instruments as we
 have deemed necessary or advisable for the purposes of this opinion.  For
 purposes of our opinion rendered in paragraph 1 below, with respect to the
 authority of State Street to operate as a national banking association and
 exercise trust powers, our opinion relies upon and is limited by such
 Certificate of the Comptroller of the Currency.

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

      When an opinion set forth below is given to the best of our knowledge,
 or to our knowledge, or with reference to matters of which we are aware or
 which are known to us, or with another similar qualification, the relevant
 knowledge or awareness is limited to the actual knowledge or awareness of
 the individual lawyer in the firm that signed this opinion, the individual
 lawyers in the firm who have participated directly in the specific
 transactions to which this opinion relates and the partner of the firm
 responsible for State Street corporate trust matters, and without any
 special or additional investigation undertaken for the purposes of this
 opinion.

      Subject to the limitation set forth below, we have made such
 examination of law as we have deemed necessary for the purposes of this
 opinion.  The opinions set forth below are limited solely to the internal
 substantive laws of the State of Connecticut as applied by courts located
 in Connecticut and the federal laws of the United States.  No opinion is
 given herein as to the choice of law or internal substantive rules of law
 that any court or other tribunal may apply to the transactions contemplated
 by the Operative Documents.  No opinion is expressed herein as to the
 application or effect of federal securities laws or as to the securities or
 so-called "Blue Sky" laws of any state or other jurisdiction.  In addition,
 no opinion is expressed as to matters governed by any law, statute, rule or
 regulation of the United States relating to the acquisition, ownership,
 registration, use, operation, maintenance, repair, replacement or sale of
 or the nature of the Aircraft.

      To the extent to which this opinion deals with matters governed by or
 relating to the laws of the State of New York, or other jurisdiction other
 than the State of Connecticut, by which the Operative Documents are stated
 to be governed, we have assumed, with your permission that the Operative
 Documents are governed by the internal substantive laws of the State of
 Connecticut.

      Our opinion is further subject to the following exceptions,
 qualifications and assumptions:

            1. We have assumed without any independent investigation that
      (i) each party to the Operative Documents, other than State Street,
      in its individual capacity or as Subordination Agent, as applicable,
      at all times relevant thereto, is validly existing and in good
      standing under the laws of the jurisdiction in which it is organized,
      and is qualified to do business and in good standing under the laws
      of each jurisdiction where such qualification is required generally
      or necessary in order for such party to enforce its rights under such
      Operative Documents, and (ii) each party to the Operative Documents,
      at all times relevant thereto, had and has the full power, authority
      and legal right under its certificate of incorporation, partnership
      agreement, bylaws, and other governing organizational documents, and
      the applicable corporate, partnership, or other enterprise
      legislation and other applicable laws, as the case may be (other than
      State Street and the Subordination Agent with respect to the laws of
      the United States of America and the internal substantive laws of the
      State of Connecticut, but only in each case to the limited extent the
      same may be applicable to State Street or the Subordination Agent,
      and relevant to our opinions expressed below) to execute, and to
      perform its obligations under, the Operative Documents, and (iii)
      each party to the Operative Documents (other than State Street or the
      Subordination Agent, as applicable) has duly executed and delivered
      each of such agreements and instruments to which it is a party and
      that (other than with respect to State Street and the Subordination
      Agent, as applicable) the execution and delivery of such agreements
      and instruments and the transactions contemplated thereby have been
      duly authorized by proper corporate or other organizational
      proceedings as to such party.

            2. We have assumed without any independent investigation (i)
      that each of the Operative Documents is a valid, binding and
      enforceable obligation of each party thereto other than State Street
      or the Subordination Agent, as applicable, and (ii) that each of the
      Operative Documents is a valid, binding and enforceable obligation of
      State Street or the Subordination Agent, as applicable, to the extent
      that laws other than those of the State of Connecticut are relevant
      thereto (other than the laws of the United States of America, but
      only to the limited extent the same may be applicable to State Street
      or the Subordination Agent, as applicable, and relevant to our
      opinions expressed below).

            3. The enforcement of any obligations of State Street or the
      Subordination Agent, as applicable, under any of the Operative
      Documents may be limited by the receivership, conservatorship and
      supervisory powers of bank regulatory agencies generally, as well as
      by bankruptcy, insolvency, reorganization, moratorium, marshaling or
      other laws and rules of law affecting the enforcement generally of
      creditors' rights and remedies (including such as may deny giving
      effect to waivers of debtors' or guarantors' rights); and we express
      no opinion as to the status under any fraudulent conveyance laws or
      fraudulent transfer laws of any of the obligations of State Street or
      the Subordination Agent, as applicable, under any of the Operative
      Documents.

            4. We express no opinion as the availability of any specific or
      equitable relief of any kind.

            5. The enforcement of any of your rights may in all cases be
      subject to an implied duty of good faith and fair dealing and to
      general principles of equity (regardless of whether such
      enforceability is considered in a proceeding at law or in equity)
      and, as to any of your rights to collateral security, will be subject
      to a duty to act in a commercially reasonable manner.

            6. We express no opinion as to the enforceability of any
      particular provision of any of the Operative Documents relating to
      (i) waivers of rights to object to jurisdiction or venue, or consents
      to jurisdiction or venue, (ii) waivers of rights to (or methods of)
      service of process, or rights to trial by jury, or other rights or
      benefits bestowed by operation of law, (iii) waivers of any
      applicable defenses, setoffs, recoupments, or counterclaims, (iv) the
      grant of powers of attorney to any person or entity, (v) exculpation
      or exoneration clauses, indemnity clauses, and clauses relating to
      releases or waivers of unmatured claims or rights, (vi) the
      imposition or collection of interest on overdue interest or providing
      for a penalty rate of interest or late charges on overdue or
      defaulted obligations, or the payment of any premium, liquidated
      damages, or other amount which may be held by any court to be a
      "penalty" or a "forfeiture," or (vii) so-called "usury savings
      clauses" purporting to specify methods of (or otherwise assure)
      compliance with usury laws or other similar laws of any jurisdiction.

            7. We express no opinion as to the effect of events occurring,
      circumstances arising, or changes of law becoming effective or
      occurring, after the date hereof on the matters addressed in this
      opinion letter, and we assume no responsibility to inform you of
      additional or changed facts, or changes in law, of which we may
      become aware.

            8. No opinion is given herein as to the effect of usury laws
      (or other similar laws) of any jurisdiction with respect to the
      Operative Documents.

      This opinion is rendered solely for the benefit of those institutions
 listed on Schedule A hereto and their successors and assigns in connection
 with the transactions contemplated by the Operative Documents and may not
 be used or relied upon by any other person or for any other purpose.

      Based upon the foregoing and subject to the limitations and
 qualifications set forth herein, we are of the opinion that:

      1.   State Street is a national banking association, validly formed
 and authorized to operate as a national banking association under the laws
 of the United States of America and, in its individual capacity or as
 Subordination Agent, as the case may be, has the requisite corporate and
 trust power and authority to execute, deliver and perform its obligations
 under the Operative Documents.

      2.   State Street, in its individual capacity or as Subordination
 Agent, as the case may be, has duly authorized the Operative Documents by
 all necessary corporate or trust action and has duly executed and delivered
 the Operative Documents, and the Operative Documents constitute valid and
 binding obligations of State Street, in its individual capacity or as
 Subordination Agent, as the case may be, enforceable against State Street,
 in its individual capacity or as Subordination Agent, as the case may be,
 in accordance with their respective terms.

      3.   The authorization, execution, delivery and performance by State
 Street, in its individual capacity or as Subordination Agent, as the case
 may be, of the Operative Documents and the consummation of the transactions
 therein contemplated and compliance with the terms thereof do not and will
 not result in the violation of the provisions of the charter documents or
 by-laws of State Street and, to the best of our knowledge, do not conflict
 with, or result in a breach of any terms or provisions of, or constitute a
 default under, or result in the creation or the imposition of any lien,
 charge or encumbrance upon any property or assets of State Street under any
 indenture, mortgage or other agreement or instrument, in each case known to
 us, to which State Street is a party or by which it is bound, or violates
 any applicable Connecticut or federal law, rule or regulation governing
 State Street's banking or trust powers, or, to the best of our knowledge,
 of any judgment, order or decree, in each case known to us, applicable to
 State Street of any court, regulatory body, administrative agency,
 government or governmental body having jurisdiction over State Street.

      4.   No authorization, approval, consent, license or order of, giving
 of notice to, registration with, or taking of any other action in respect
 of, any federal or state governmental authority or agency pursuant to any
 federal or Connecticut law governing the banking or trust powers of State
 Street is required for the authorization, execution, delivery and
 performance by State Street, in its individual capacity or as Subordination
 Agent, as the case may be, of the Operative Documents or the consummation
 of any of the transactions by State Street, in its individual capacity or
 as Subordination Agent, as the case may be, contemplated thereby (except as
 shall have been duly obtained, given or taken); and such authorization,
 execution, delivery, performance, consummation and issuance do not conflict
 with or result in a breach of the provisions of any such law.

      5.   There are no taxes, fees or other governmental charges payable
 under the laws of the State of Connecticut or any political subdivision of
 such State in connection with the execution and delivery by State Street,
 in its individual capacity or as Subordination Agent, as the case may be,
 of the Operative Documents (except for taxes on any fees payable to State
 Street in its individual capacity) which are imposed solely because State
 Street has its principal place of business in Connecticut or performs its
 administrative duties under the Operative Documents in Connecticut.

      6.   To our knowledge, but without having investigated any
 governmental records or court dockets, and without having made any other
 independent investigation, there are no proceedings pending or overtly
 threatened in writing against or affecting State Street in any court or
 before any governmental authority, agency, arbitration board or tribunal
 which, if adversely determined, individually or in the aggregate, could
 reasonably be expected to affect materially and adversely the trust related
 to the Indenture or affect the right, power and authority of State Street,
 in its individual capacity or as Subordination Agent, as the case may be,
 to enter into or perform its obligations under the Operative Documents.

      7.   Assuming that the Subordination Agent holds each of the Equipment
 Notes delivered to and registered in its name pursuant to and as required
 by the Intercreditor Agreement, it holds such Equipment Notes in trust as
 trustee for the related Pass Through Trustee in the exercise of the
 fiduciary powers conferred upon State Street by Connecticut law.

                               Very truly yours,


                               BINGHAM DANA LLP

  for the security and benefit of the Note Holders, a first priority
  security interest in and mortgage lien on all right, title and interest
  of Owner in, to and under the following described property, rights and
  privileges, to wit:

             (1)  the Aircraft (including the Airframe and the Engines and
  all replacements thereof and substitutions therefor to which Owner shall

  particularly described in the Indenture Supplement executed and delivered

  of this Indenture or required hereby to be held by the Indenture Trustee
  hereunder; and

             (6)  all proceeds of the foregoing.

             Concurrently with the delivery hereof, Owner is delivering to
  the Indenture Trustee executed copies of the Participation Agreement, the
  French Pledge Agreement and the Purchase Agreement Assignment with the
  Consent and Agreement attached thereto.

             TO HAVE AND TO HOLD all and singular the aforesaid property
  unto the Indenture Trustee, and its successors and assigns, in trust for
  the benefit and security of the Note Holders and the Indenture
  Indemnitees, except as provided in Section 2.15 and Article III without
  any preference, distinction or priority of any one Equipment Note over
  any other by reason of priority of time of issue, sale, negotiation, date
  of maturity thereof or otherwise for any reason whatsoever, and for the
  uses and purposes and in all cases and as to all property specified in
  paragraphs (1) through (6) inclusive above, subject to the terms and
  provisions set forth in this Indenture.

             It is expressly agreed that anything herein contained to the
  contrary notwithstanding, Owner shall remain liable under each of the
  Indenture Agreements to which it is a party to perform all of the
  obligations assumed by it thereunder, except to the extent prohibited or
  excluded from doing so pursuant to the terms and provisions thereof, and
  the Indenture Indemnitees, Indenture Trustee and the Note Holders shall
  have no obligation or liability under the Indenture Agreements, by reason
  of or arising out of the assignment hereunder, nor shall the Indenture
  Indemnitees, Indenture Trustee or the Note Holders be required or
  obligated in any manner to perform or fulfill any obligations of Owner
  under or pursuant to any of the Indenture Agreements to which it is a
  party, or, except as herein expressly provided, to make any payment, or
  to make any inquiry as to the nature or sufficiency of any payment
  received by it, or present or file any claim, or take any action to
  collect or enforce the payment of any amounts which may have been
  assigned to it or to which it may be entitled at any time or times.

             Notwithstanding the above, the Indenture Trustee agrees, for
  the benefit of AVSA, S.A.R.L., that in exercising or assigning its rights
  under the Purchase Agreement Assignment, the terms and conditions of the
  Purchase Agreement Assignment shall apply, and be binding upon, the
  Indenture Trustee.

             Owner does hereby constitute the Indenture Trustee the true
  and lawful attorney of Owner, irrevocably, granted for good and valuable
  consideration and coupled with an interest and with full power of
  substitution, and with full power (in the name of Owner or otherwise) to
  ask for, require, demand, receive, compound and give acquittance for any
  and all monies and claims for monies (in each case including insurance
  and requisition proceeds) due and to become due under or arising out of
  the Indenture Agreements, and all other property which now or hereafter
  constitutes part of the Indenture Estate, to endorse any checks or other
  instruments or orders in connection therewith and to file any claims or
  to take any action or to institute any proceedings which the Indenture
  Trustee may deem to be necessary or advisable in the premises. Without
  limiting the generality of the foregoing, but subject to the rights of
  Owner  hereunder, during the continuance of any Event of Default under
  this Indenture, the Indenture Trustee shall have the right under such
  power of attorney to accept any offer in connection with the exercise of
  remedies as set forth herein of any purchaser to purchase the Airframe
  and Engines and upon such purchase to execute and deliver in the name of
  and on behalf of Owner an appropriate bill of sale and other instruments
  of transfer relating to the Airframe and Engines, when purchased by such
  purchaser, and to perform all other necessary or appropriate acts with
  respect to any such purchase, and in its discretion to file any claim or
  take any other action or proceedings, either in its own name or in the
  name of Owner or otherwise, which the Indenture Trustee may deem
  necessary or appropriate to protect and preserve the right, title and
  interest of the Indenture Trustee in and to such rents and other sums and
  the security intended to be afforded hereby; provided, however, that no
  action of the Indenture Trustee pursuant to this paragraph shall increase
  the obligations or liabilities of Owner to any Person beyond those
  obligations and liabilities specifically set forth in this Indenture and
  in the other Operative Documents.  Owner agrees that promptly upon
  receipt thereof, it will transfer to the Indenture Trustee any and all
  monies from time to time received by it constituting part of the
  Indenture Estate, for distribution by the Indenture Trustee pursuant to
  this Indenture.

             Owner agrees that at any time and from time to time, upon the
  written request of the Indenture Trustee, Owner will promptly and duly
  execute and deliver or cause to be duly executed and delivered any and
  all such further instruments and documents as the Indenture Trustee may
  reasonably deem necessary or desirable to perfect, preserve or protect
  the mortgage, security interests and assignments created or intended to
  be created hereby or to obtain for the Indenture Trustee the full
  benefits of the assignment hereunder and of the rights and powers herein
  granted.

             Owner does hereby warrant and represent that it has not
  assigned or pledged, and hereby covenants and agrees that, except as
  permitted by the terms hereof, it will not assign or pledge, so long as
  the assignment hereunder shall remain in effect, and the Lien hereof
  shall not have been released pursuant to Section 11.01, any of its right,
  title or interest hereby assigned, to anyone other than the Indenture
  Trustee, and that it will not, except as otherwise provided in this
  Indenture, (i) enter into any agreement amending or supplementing any
  Indenture Agreement, (ii) execute any waiver or modification of, or
  consent under, the terms of, or exercise any rights, powers or privileges
  under, any Indenture Agreement, (iii) settle or compromise any claim
  arising under any Indenture Agreement or (iv) submit or consent to the
  submission of any dispute, difference or other matter arising under or in
  respect of any Indenture Agreement to arbitration thereunder.

             Owner does hereby further agree that, except as permitted by
  the terms hereof, it will not without the written consent of the
  Indenture Trustee sell, mortgage, transfer, assign or hypothecate (other
  than to the Indenture Trustee hereunder) its interest in the Airframe and
  Engines or any part thereof or in any amount to be received by it from
  the use or disposition of the Airframe and Engines, other than amounts
  distributed to it pursuant to Article III.

             It is hereby further agreed that any and all property
  described or referred to in the granting clauses hereof which is
  hereafter acquired by Owner shall ipso facto, and without any further
  conveyance, assignment or act on the part of Owner or the Indenture
  Trustee, become and be subject to the Lien herein granted as fully and
  completely as though specifically described herein, but nothing contained
  in this paragraph shall be deemed to modify or change the obligations of
  Owner contained in the foregoing paragraphs.

             Owner does hereby agree that it will not violate any covenant
  or agreement made by it, herein or in any of the other Owner Documents.

             IT IS HEREBY COVENANTED AND AGREED by and between the parties
  hereto as follows:

  Principal Amount and all accrued and unpaid interest on, and any other
  amounts due under, this Equipment Note.  Notwithstanding anything to the
  contrary contained herein, if any date on which a payment under this
  Equipment Note becomes due and payable is not a Business Day then such
  payment shall not be made on such scheduled date but shall be made on the
  next succeeding Business Day with the same force and effect as if made on
  such scheduled date and if such payment is made on such next succeeding
  Business Day, no interest shall accrue on the amount of such payment from
  and after such scheduled date.

          For purposes hereof, the term "Indenture" means the Indenture and
  Security Agreement (N___U_), dated as of ___________ __,  ____, between

  assigned in the Indenture.

          This Equipment Note shall bear interest, payable on demand, at the
  Past Due Rate (calculated on the basis of a year of 360 days comprised of
  twelve 30-day months) on any overdue Principal Amount, any overdue Make-
  Whole Amount, if any, and (to the extent permitted by applicable law) any
  overdue interest and any other amounts payable hereunder which are
  overdue, in each case for the period the same is overdue.  Amounts shall
  be overdue if not paid when due (whether at stated maturity, by
  acceleration or otherwise).

          There shall be maintained an Equipment Note Register for the
  purpose of registering transfers and exchanges of Equipment Notes at the
  Corporate Trust Office of the Indenture Trustee or at the office of any
  successor in the manner provided in Section 2.07 of the Indenture.

          The Principal Amount and interest and other amounts due hereunder
  shall be payable in Dollars in immediately available funds at the
  Corporate Trust Office of the Indenture Trustee, or as otherwise provided
  in the Indenture.  Each such payment shall be made on the date such
  payment is due and without any presentment or surrender of this Equipment
  Note, except that in the case of any final payment with respect to this
  Equipment Note, the Equipment Note shall be surrendered promptly
  thereafter to the Indenture Trustee for cancellation.

          The holder hereof, by its acceptance of this Equipment Note,
  agrees that, except as provided in the Indenture, each payment of an
  installment of the Principal Amount, Make-Whole Amount, if any, and
  interest received by it hereunder shall be applied, first, to the payment
  of accrued interest on this Equipment Note (as well as any interest on
  any overdue Principal Amount, any overdue Make-Whole Amount, if any, or,
  to the extent permitted by Law, any overdue interest and other amounts
  hereunder) to the date of such payment, second, to the payment of the
  Principal Amount of this Equipment Note (or portion hereof) then due
  (other than by reason of redemption), third, to the payment of Make-Whole
  Amount, if any, and any other amount due hereunder or under the
  Indenture, and fourth, the balance, if any, remaining thereafter, to the
  payment of the Principal Amount hereof remaining unpaid and due by reason
  of redemption.  The amounts paid pursuant to clause fourth of the
  preceding sentence shall be applied to installments of the Principal
  Amount of this Equipment Note remaining unpaid in the inverse order of
  their normal maturity.

          This Equipment Note is one of the Equipment Notes referred to in
  the Indenture which have been or are to be issued by Owner pursuant to
  the terms of the Indenture.  The Indenture Estate is held by the
  Indenture Trustee as security, in part, for the Equipment Notes.  The

  and conditions in the Indenture and the Participation Agreement each
  holder hereof agrees by its acceptance of this Equipment Note.

  therein set forth, this Equipment Note is exchangeable for a like

  February 20 and August 20 thereafter until maturity.  The Principal
  Amount of each Equipment Note shall be payable on the dates and in the
  installments equal to the corresponding amount as set forth on Schedule I
  attached to the Equipment Notes.  Notwithstanding the foregoing, the
  final payment made under each Equipment Note shall be in an amount
  sufficient to discharge in full the unpaid Principal Amount and all
  accrued and unpaid interest on, and any other amounts due under, such
  Equipment Note.  Each Equipment Note shall bear interest at the Past Due
  Rate (calculated on the basis of a year of 360 days comprised of twelve
  30-day months) on any part of the Principal Amount, Make-Whole Amount, if
  any, and to the extent permitted by applicable law, interest and any
  other amounts payable thereunder not paid when due for any period during
  which the same shall be overdue, in each case for the period the same is
  overdue.  Amounts shall be overdue if not paid when due (whether at
  stated maturity, by acceleration or otherwise).  Notwithstanding anything
  to the contrary contained herein, if any date on which a payment under
  any Equipment Note becomes due and payable is not a Business Day then
  such payment shall not be made on such scheduled date but shall be made
  on the next succeeding Business Day with the same force and effect as if
  made on such scheduled date and if such payment is made on such next
  succeeding Business Day, no interest shall accrue on the amount of such
  payment from and after such scheduled date.

            Owner agrees to pay to the Indenture Trustee for distribution
  in accordance with Section 3.04  (i) to the extent not payable (whether
  or not in fact paid) under Section 7(a) of the Note Purchase Agreement,
  an amount or amounts equal to the fees payable to (x) the Liquidity
  Provider under Section 2.03 of each Liquidity Facility and the related
  Fee Letter (as defined in the Intercreditor Agreement) multiplied by a
  fraction the numerator of which shall be the then outstanding aggregate
  principal amount of the Series G Equipment Notes and Series C Equipment
  Notes and the denominator of which shall be the then outstanding
  aggregate principal amount of all "Series G Equipment Notes" and "Series
  C Equipment Notes" (in each case as defined in the relevant Operative
  Indenture) issued under the Operative Indentures and (y) the Policy
  Provider under the Policy Fee Letter (as defined in the Policy Provider
  Agreement) multiplied by a fraction the numerator of which shall be the
  sum of the then outstanding aggregate principal amount of the Series G
  Equipment Notes and the denominator of which shall be the sum of the then
  outstanding aggregate principal amount of all "Series G Equipment Notes"
  (in each case as defined in the relevant Operative Indenture) issued
  under the Operative Indentures; (ii) (x) the amount equal to interest on
  any Downgrade Advance (other than any Applied  Downgrade Advance) payable
  under Section 3.07 of each Liquidity Facility minus Investment Earnings
  from such Downgrade Advance multiplied by (y) the fraction specified in
  the foregoing clause (i); (iii) (x) the amount equal to interest on any
  Non-Extension Advance (other than any Applied Non-Extension Advance)
  payable under Section 3.07 of each Liquidity Facility minus Investment
  Earnings from such Non-Extension Advance multiplied by (y) the fraction
  specified in the foregoing clause (i); (iv) if any payment default shall
  have occurred and be continuing with respect to interest on any Series G
  Equipment Note or Series C Equipment Note, (x) the excess, if any, of (1)
  an amount equal to interest on any Unpaid Advance,  Applied Downgrade
  Advance or Applied Non-Extension Advance payable under  Section 3.07 of
  each Liquidity Facility (or, in the case of the Series G Equipment Notes,
  if the Policy Provider has made a payment equivalent to such an Advance,
  as would have been payable under Section 3.07 of the applicable Liquidity
  Facility in respect of the Class G Pass Through Certificates had such
  Advance been made) over (2) the sum of Investment Earnings from any Final
  Advance plus any amount of interest at the Past Due Rate actually payable
  (whether or not in fact paid) by Owner in respect of the overdue
  scheduled interest on the Equipment Notes in respect of which such Unpaid
  Advance, Applied Downgrade Advance or Applied Non-Extension Advance was
  made by the applicable Liquidity Provider (or, in the case of the Series
  G Equipment Notes, an equivalent payment was made by the Policy Provider)
  multiplied by (y) a fraction the  numerator of which shall be the then
  aggregate overdue amounts of interest on the Series G Equipment Notes and
  Series C Equipment Notes (other than interest becoming due and payable
  solely as a result of acceleration of any such Equipment Notes) and the
  denominator of which shall be the then aggregate overdue amounts of
  interest on all "Series G Equipment Notes" and "Series C Equipment Notes"
  (in each case as defined in the relevant Operative Indenture) issued
  under the Operative Indentures (other than interest becoming due and
  payable solely as a result of acceleration of any such "Equipment Notes,"
  (in each case as defined in the relevant Operative Indenture) issued
  under the Operative Indentures); (v) any other amounts owed to the
  Liquidity  Provider by the Subordination Agent as borrower under each
  Liquidity Facility (other  than  amounts due as repayment of advances
  thereunder or as interest on such advances), except to the extent payable
  pursuant to clause (i), (ii),  (iii) or (iv) above multiplied by the
  fraction specified in the foregoing clause (i); (vi) all compensation and
  reimbursement of expenses, disbursements and  advances payable by Owner
  under the Pass Through Trust Agreements multiplied by the fraction
  specified in the foregoing clause (i); (vii) Owner's pro rata share of
  (I) all compensation and reimbursement of expenses and disbursements
  payable to the Subordination Agent under the Intercreditor Agreement
  except with respect to any income or franchise taxes incurred by the
  Subordination Agent in connection with the transactions contemplated by
  the Intercreditor Agreement and (II) all amounts for which the Policy
  Provider is entitled to reimbursement under Section 3.7(i) of the
  Intercreditor Agreement and (viii) without duplication of any amounts
  paid or payable pursuant to clauses (i) through (vii) above, Owner's pro
  rata share of any amount payable under Section 6(b) of the Participation
  Agreement to any Pass Through Indemnitee to the extent such amount
  relates to, results from or arises out of or in connection with (i) the
  Pass Through Trust Agreement or the enforcement of any of the terms of
  any Pass Through Document, (ii) the offer, sale, or delivery of the Pass
  Through Certificates or any interest therein or represented thereby or
  (iii) any breach of or failure to perform or observe, or any other
  noncompliance with, any covenant or agreement or other obligation to be
  performed by Owner under any Pass Through Document or the falsity of any
  representation or warranty of Owner in any Pass Through Document.  As
  used herein, "Owner's pro rata share" means as of any time a fraction,
  the numerator of which is the principal balance then outstanding of
  Equipment Notes and the denominator of which  is the aggregate principal
  balance then outstanding of all "Equipment Notes" (in each case as
  defined in the relevant Operative Indenture) issued under the Operative
  Indentures.  For purposes of this paragraph, the terms "Applied Downgrade
  Advance", "Applied Non-Extension Advance", "Cash Collateral Account",
  "Downgrade Advance", "Final Advance", "Investment Earnings", "Non-
  Extension Advance" and "Unpaid Advance" shall have the meanings specified
  in each Liquidity Facility or the Intercreditor Agreement.

            The Equipment Notes shall be executed on behalf of Owner by its
  President or one of its Vice Presidents, Assistant Vice Presidents or
  Assistant Secretaries or other authorized officer.  Equipment Notes
  bearing the signatures of individuals who were at any time the proper
  officers of Owner shall bind Owner, notwithstanding that such individuals
  or any of them have ceased to hold such offices prior to the
  authentication and delivery of such Equipment Notes or did not hold such
  offices at the respective dates of such Equipment Notes. Owner may from
  time to time execute and deliver Equipment Notes with respect to the
  Aircraft to the Indenture Trustee for authentication upon original issue
  and such Equipment Notes shall thereupon be authenticated and delivered
  by the Indenture Trustee upon the written request of Owner signed by a
  Vice President or Assistant Vice President or other authorized officer of
  Owner; provided, however, that each such request shall specify the
  aggregate Principal Amount of all Equipment Notes to be authenticated
  hereunder on original issue with respect to the Aircraft. No Equipment
  Note shall be secured by or entitled to any benefit under this Indenture
  or be valid or obligatory for any purposes, unless there appears on such
  Equipment Note a certificate of authentication in the form provided for
  herein executed by the Indenture Trustee by the manual signature of one
  of its authorized officers and such certificate upon any Equipment Notes
  shall be conclusive evidence, and the only evidence, that such Equipment
  Note has been duly authenticated and delivered hereunder.

            SECTION 2.03.   [Reserved].

            SECTION 2.04.   Method of Payment.

            (a)  The Principal Amount of, interest on, Make-Whole Amount,
  if any, and other amounts due under each Equipment Note or hereunder will
  be payable in Dollars by wire transfer of immediately available funds not
  later than 11:00 a.m., New York City time, on the due date of payment to
  the Indenture Trustee at the Corporate Trust Office for distribution
  among the Note Holders in the manner provided herein.  Owner shall not
  have any responsibility for the distribution of such payment to any Note
  Holder. Notwithstanding the foregoing or any provision in any Equipment
  Note to the contrary, the Indenture Trustee will use reasonable efforts
  to pay or cause to be paid, if so directed in writing by any Note Holder
  (with a copy to Owner), all amounts paid by Owner hereunder and under
  such holder's Equipment Note or Equipment Notes to such holder or a
  nominee therefor (including all amounts distributed pursuant to Article
  III of this Indenture) by transferring, or causing to be transferred, by
  wire transfer of immediately available funds in Dollars, prior to 2:00
  p.m., New York City time, on the due date of payment, to an account
  maintained by such holder with a bank located in the continental United
  States the amount to be distributed to such holder, for credit to the
  account of such holder maintained at such bank. If the Indenture Trustee
  shall fail to make any such payment as provided in the immediately
  preceding sentence after its receipt of funds at the place and prior to
  the time specified above, the Indenture Trustee, in its individual
  capacity and not as trustee, agrees to compensate such holders for loss
  of use of funds at the Federal Funds Rate until such payment is made and
  the Indenture Trustee shall be entitled to any interest earned on such
  funds until such payment is made.  Any payment made hereunder shall be
  made without any presentment or surrender of any Equipment Note, except
  that, in the case of the final payment in respect of any Equipment Note,
  such Equipment Note shall be surrendered to the Indenture Trustee for
  cancellation promptly after such payment.  Notwithstanding any other
  provision of this Indenture to the contrary, the Indenture Trustee shall
  not be required to make, or cause to be made, wire transfers as aforesaid
  prior to the first Business Day on which it is practicable for the
  Indenture Trustee to do so in view of the time of day when the funds to
  be so transferred were received by it if such funds were received after
  11:00 a.m., New York City time, at the place of payment.  Prior to the
  due presentment for registration of transfer of any Equipment Note, Owner
  and the Indenture Trustee shall deem and treat the Person in whose name
  any Equipment Note is registered on the Equipment Note Register as the
  absolute owner and holder of such Equipment Note for the purpose of
  receiving payment of all amounts payable with respect to such Equipment
  Note and for all other purposes, and neither Owner nor the Indenture
  Trustee shall be affected by any notice to the contrary.  So long as any
  signatory to the Participation Agreement or nominee thereof shall be a
  registered Note Holder, all payments to it shall be made to the account
  of such Note Holder specified in Schedule I thereto and otherwise in the
  manner provided in or pursuant to the Participation Agreement unless it
  shall have specified some other account or manner of payment by notice to
  the Indenture Trustee consistent with this Section 2.04.

            (b)  The Indenture Trustee, as agent for Owner, shall exclude
  and withhold at the appropriate rate from each payment of Principal
  Amount of, interest on, Make-Whole Amount, if any, and other amounts due
  hereunder or under each Equipment Note (and such exclusion and
  withholding shall constitute payment in respect of such Equipment Note)
  any and all United States withholding taxes applicable thereto as
  required by Law.  The Indenture Trustee agrees to act as such withholding
  agent and, in connection therewith, whenever any present or future United
  States taxes or similar charges are required to be withheld with respect
  to any amounts payable hereunder or in respect of the Equipment Notes, to
  withhold such amounts (and such withholding shall constitute payment in
  respect of such Equipment Note) and timely pay the same to the
  appropriate authority in the name of and on behalf of the Note Holders,
  that it will file any necessary United States withholding tax returns or
  statements when due, and that as promptly as possible after the payment
  thereof it will deliver to each Note Holder (with a copy to Owner)
  appropriate receipts showing the payment thereof, together with such
  additional documentary evidence as any such Note Holder may reasonably
  request from time to time.

            If a Note Holder which is a Non-U.S. Person has furnished to
  the Indenture Trustee a properly completed and currently effective U.S.
  Internal Revenue Service Form 1001, W-8 or W-8BEN (or such successor form
  or forms as may be required by the United States Treasury Department)
  during the calendar year in which the payment hereunder or under the
  Equipment Note(s) held by such holder is made (but prior to the making of
  such payment), or in either of the two preceding calendar years, and has
  not notified the Indenture Trustee of the withdrawal or inaccuracy of
  such form prior to the date of such payment (and the Indenture Trustee
  has no reason to know that any information set forth in such form is
  inaccurate), the Indenture Trustee shall withhold only the amount, if
  any, required by Law (after taking into account any applicable exemptions
  claimed by the Note Holder) to be withheld from payments hereunder or
  under the Equipment Notes held by such holder in respect of United States
  federal income tax (and such withholding shall constitute payment in
  respect of such Equipment Note).  If a Note Holder (x) which is a Non-
  U.S. Person has furnished to the Indenture Trustee a properly completed
  and currently effective U.S. Internal Revenue Service Form 4224 or W-8ECI
  in duplicate (or such successor certificate, form or forms as may be
  required by the United States Treasury Department as necessary in order
  to avoid withholding of United States federal income tax), during the
  calendar year in which the payment is made (but prior to the making of
  such payment), and has not notified the Indenture Trustee of the
  withdrawal or inaccuracy of such certificate or form prior to the date of
  such payment (and the Indenture Trustee has no reason to know that any
  information set forth in such form is inaccurate) or (y) which is a U.S.
  Person has furnished to the Indenture Trustee a properly completed and
  currently effective U.S. Internal Revenue Service Form W-9 (or such
  successor form or forms as may be required by the United States Treasury
  Department), if applicable, prior to a payment hereunder or under the
  Equipment Notes held by such holder, no amount shall be withheld from
  payments in respect of United States federal income tax.  If any Note
  Holder has notified the Indenture Trustee that any of the foregoing forms
  or certificates is withdrawn or inaccurate, or if such holder has not
  filed a form claiming an exemption from United States withholding tax or
  if the Code or the regulations thereunder or the administrative
  interpretation thereof are at any time after the date hereof amended to
  require such withholding of United States federal income taxes from
  payments under the Equipment Notes held by such holder, the Indenture
  Trustee agrees to withhold from each payment due to the relevant Note
  Holder withholding taxes at the appropriate rate under Law and will, on a
  timely basis as more fully provided above, deposit such amounts with an
  authorized depository and make such returns, statements, receipts and
  other documentary evidence in connection therewith as required by
  applicable law.  Owner shall not be liable if the Indenture Trustee fails
  to withhold withholding taxes in accordance with this Section 2.04 or if
  any Note Holder provides false or inaccurate information on any form
  required to be delivered under this Section 2.04.

            SECTION 2.05.   Application of Payments.

            In the case of each Equipment Note, each payment of Principal
  Amount, Make-Whole Amount, if any, and interest or other amounts due
  thereon shall be applied:

            First:  to the payment of accrued interest on such Equipment
  Note (as well as any interest on any overdue Principal Amount, any
  overdue Make-Whole Amount, if any, and to the extent permitted by Law,
  any overdue interest and any other overdue amounts thereunder) to the
  date of  such payment;

            Second:  to the payment of the Principal Amount of such
  Equipment Note (or a portion thereof) then due thereunder (other than by
  reason of redemption);

            Third:  to the payment of Make-Whole Amount, if any, and any
  other amount due hereunder or under such Equipment Note; and

            Fourth:  the balance, if any, remaining thereafter, to the
  payment of the Principal Amount of such Equipment Note remaining unpaid
  and due by reason of redemption (provided that such Equipment Note shall
  not be subject to redemption except as provided in Sections 2.10, 2.11
  and 2.12).

            The amounts paid pursuant to clause "Fourth" above shall be
  applied to the installments of Principal Amount of such Equipment Note in
  the inverse order of their normal maturity.  Notwithstanding the
  foregoing, each indemnity payment or payment of transaction costs or
  expenses received hereunder or under another Operative Document shall be
  applied for the purpose (directly or by reimbursement) for which such
  amount was paid.

            SECTION 2.06.   Termination of Interest in Indenture Estate.

            A Note Holder and Indenture Indemnitees shall not, as such,
  have any further interest in, or other right with respect to, the
  Indenture Estate when and if the Secured Obligations due to such Note
  Holder or Indenture Indemnitee shall have been paid in full.

            SECTION 2.07.   Registration, Transfer and Exchange of
  Equipment Notes.

            The Indenture Trustee shall keep a register (the "Equipment
  Note Register") in which the Indenture Trustee shall provide for the
  registration of Equipment Notes and the registration of transfers of
  Equipment Notes. No such transfer shall be given effect unless and until
  registration hereunder shall have occurred.  The Equipment Note Register
  shall be kept at the Corporate Trust Office of the Indenture Trustee.
  The Indenture Trustee is hereby appointed "Equipment Note Registrar" for
  the purpose of registering Equipment Notes and transfers of Equipment
  Notes as herein provided. A holder of any Equipment Note intending to
  exchange such Equipment Note shall surrender such Equipment Note to the
  Indenture Trustee at the Corporate Trust Office, together with a written
  request from the registered holder thereof for the issuance of a new
  Equipment Note, specifying, in the case of a surrender for transfer, the
  name and address of the new holder or holders.  Upon surrender for
  registration of transfer of any Equipment Note, Owner shall execute, and
  the Indenture Trustee shall authenticate and deliver, in the name of the
  designated transferee or transferees, one or more new Equipment Notes of
  a like aggregate Principal Amount and of the same series.  At the option
  of the Note Holder, Equipment Notes may be exchanged for other Equipment
  Notes of any authorized denominations of a like aggregate Principal
  Amount, upon surrender of the Equipment Notes to be exchanged to the
  Indenture Trustee at the Corporate Trust Office.  Whenever any Equipment
  Notes are so surrendered for exchange, Owner shall execute, and the
  Indenture Trustee shall authenticate and deliver, the Equipment Notes
  which the Note Holder making the exchange is entitled to receive.  All
  Equipment Notes issued upon any registration of transfer or exchange of
  Equipment Notes (whether under this Section 2.07 or under Section 2.08 or
  otherwise under this Indenture) shall be the valid obligations of Owner
  evidencing the same respective obligations, and entitled to the same
  security and benefits under this Indenture, as the Equipment Notes
  surrendered upon such registration of transfer or exchange.  Every
  Equipment Note presented or surrendered for registration of transfer,
  shall (if so required by the Indenture Trustee) be duly endorsed, or be
  accompanied by a written instrument of transfer in form satisfactory to
  the Indenture Trustee duly executed by the Note Holder or such holder's
  attorney duly authorized in writing, and the Indenture Trustee shall
  require evidence satisfactory to it as to the compliance of any such
  transfer with the Securities Act, and the securities Laws of any
  applicable state.  The Indenture Trustee shall make a notation on each
  new Equipment Note of the amount of all payments of Principal Amount
  previously made on the old Equipment Note or Equipment Notes with respect
  to which such new Equipment Note is issued and the date to which interest
  on such old Equipment Note or Equipment Notes has been paid.  Interest
  shall be deemed to have been paid on such new Equipment Note to the date
  on which interest shall have been paid on such old Equipment Note, and
  all payments of the Principal Amount marked on such new Equipment Note,
  as provided above, shall be deemed to have been made thereon.  Owner
  shall not be required to exchange any surrendered Equipment Notes as
  provided above during the ten-day period preceding the due date of any
  payment on such Equipment Note.  Owner shall in all cases deem the Person
  in whose name any Equipment Note shall have been issued and registered as
  the absolute owner and holder of such Equipment Note for the purpose of
  receiving payment of all amounts payable by Owner with respect to such
  Equipment Note and for all purposes until a notice stating otherwise is
  received from the Indenture Trustee and such change is reflected on the
  Equipment Note Register.  The Indenture Trustee will promptly notify
  Owner of each registration of a transfer of an Equipment Note.  Any such
  transferee of an Equipment Note, by its acceptance of an Equipment Note,
  agrees to the provisions of the Participation Agreement applicable to
  Note Holders, and shall be deemed to have represented and warranted
  (except as provided above), and covenanted, to the parties to the
  Participation Agreement as to the matters represented, warranted and
  covenanted by the Loan Participants in the Participation Agreement.
  Subject to compliance by the Note Holder and its transferee (if any) of
  the requirements set forth in this Section 2.07, the Indenture Trustee
  and Owner shall use all reasonable efforts to issue new Equipment Notes
  upon transfer or exchange within ten (10) Business Days of the date an
  Equipment Note is surrendered for transfer or exchange.

            SECTION 2.08.   Mutilated, Destroyed, Lost or Stolen Equipment
  Notes.

            If any Equipment Note shall become mutilated, destroyed, lost
  or stolen, Owner shall, upon the written request of the holder of such
  Equipment Note, execute and the Indenture Trustee shall authenticate and
  deliver in replacement thereof a new Equipment Note, payable in the same
  Principal Amount dated the same date and captioned as issued in
  connection with the Aircraft.  If the Equipment Note being replaced has
  become mutilated, such Equipment Note shall be surrendered to the
  Indenture Trustee and a photocopy thereof shall be furnished to Owner.
  If the Equipment Note being replaced has been destroyed, lost or stolen,
  the holder of such Equipment Note shall furnish to Owner and the
  Indenture Trustee such security or indemnity as may be required by them
  to save Owner and the Indenture Trustee harmless and evidence
  satisfactory to Owner and the Indenture Trustee of the destruction, loss
  or theft of such Equipment Note and of the ownership thereof.  If a
  "qualified institutional buyer" of the type referred to in paragraph
  (a)(l)(i)(A), (B), (D) or (E) of Rule 144A under the Securities Act (a
  "QIB") is the holder of any such destroyed, lost or stolen Equipment
  Note, then the written indemnity of such QIB, signed by an authorized
  officer thereof, in favor of, delivered to and in form reasonably
  satisfactory to Owner and the Indenture Trustee shall be accepted as
  satisfactory indemnity and security and no further indemnity or security
  shall be required as a condition to the execution and delivery of such
  new Equipment Note. Subject to compliance by the Note Holder of the
  requirements set forth in this Section 2.08, the Indenture Trustee and
  Owner shall use all reasonable efforts to issue new Equipment Notes
  within ten (10) Business Days of the date of the written request therefor
  from the Note Holder.

            SECTION 2.09.   Payment of Expenses on Transfer; Cancellation.

            (a)  No service charge shall be made to a Note Holder for any
  registration of transfer or exchange of Equipment Notes, but the
  Indenture Trustee, as Equipment Note Registrar, may require payment from
  the party requesting such new Equipment Notes of a sum sufficient to
  cover any tax or other governmental charge that may be imposed in
  connection with any registration of transfer or exchange of Equipment
  Notes.

            (b)  The Indenture Trustee shall cancel all Equipment Notes
  surrendered for replacement, redemption, transfer, exchange, payment or
  cancellation and shall destroy the canceled Equipment Notes.

            SECTION 2.10.   Mandatory Redemptions of Equipment Notes.

            On the date on which Owner is required pursuant to Section 5.06
  to make payment for an Event of Loss with respect to the Aircraft, all of
  the Equipment Notes shall be redeemed in whole at a redemption price
  equal to 100% of the unpaid Principal Amount thereof, together with all
  accrued interest thereon to the date of redemption and all other amounts
  payable hereunder or under the Participation Agreement to the Note
  Holders but without the Make-Whole Amount.

            SECTION 2.11.   Voluntary Redemptions of Equipment Notes.

            All, but not less than all, of the Equipment Notes may be
  redeemed by Owner upon at least twenty (20) days' revocable prior written
  notice to the Indenture Trustee at a redemption price equal to 100% of
  the unpaid Principal Amount thereof, together with accrued interest
  thereon to the date of redemption and all other amounts payable hereunder
  or under the Participation Agreement to the Note Holders plus the Make-
  Whole Amount, if any.

            SECTION 2.12.   Redemptions; Notice of Redemption.

            (a)  Neither any redemption of any Equipment Note nor any
  purchase by Owner of any Equipment Note may be made except to the extent
  and in the manner expressly permitted by this Indenture.  No purchase of
  any Equipment Note may be made by the Indenture Trustee.

            (b)  Notice of redemption or purchase with respect to the
  Equipment Notes shall be given by the Indenture Trustee by first-class
  mail, postage prepaid, mailed not less than fifteen (15) nor more than
  sixty (60) days prior to the applicable redemption date, to each Note
  Holder of such Equipment Notes to be redeemed or purchased, at such Note
  Holder's address appearing in the Equipment Note Register.  All notices
  of redemption shall state:  (1) the redemption date, (2) the applicable
  basis for determining the redemption price, (3) that on the redemption
  date, the redemption price will become due and payable upon each such
  Equipment Note, and that, if any such Equipment Notes are then
  outstanding, interest on such Equipment Notes shall cease to accrue on
  and after such redemption date and (4) the place or places where such
  Equipment Notes are to be surrendered for payment of the redemption
  price.

            (c)  On or before the redemption date, Owner (or any Person on
  behalf of Owner) shall, to the extent an amount equal to the redemption
  price for the Equipment Notes to be redeemed or purchased on the
  redemption date shall not then be held in the Indenture Estate, deposit
  or cause to be deposited with the Indenture Trustee by 11:00 a.m. New
  York City time on the redemption date in immediately available funds the
  redemption price of the Equipment Notes to be redeemed or purchased.

            (d)  Notice of redemption or purchase having been given as
  aforesaid (and not revoked at least three (3) days prior to the
  redemption date), the Equipment Notes to be redeemed or purchased shall,
  on the redemption date, become due and payable at the Corporate Trust
  Office of the Indenture Trustee or at any office or agency maintained for
  such purposes pursuant to Section 2.07, and from and after such
  redemption date (unless there shall be a default in the payment of the
  redemption price) any such Equipment Notes then outstanding shall cease
  to bear interest.  Upon surrender of any such Equipment Note for
  redemption or purchase in accordance with said notice, such Equipment
  Note shall be redeemed at the redemption price.  If any Equipment Note
  called for redemption or purchase shall not be so paid upon surrender
  thereof for redemption, the principal amount thereof shall, until paid,
  continue to bear interest from the applicable redemption date at the
  interest rate in effect for such Equipment Note as of such redemption
  date.

            SECTION 2.13.   [Reserved].

            SECTION 2.14.   [Reserved].

            SECTION 2.15.   Subordination.

            (a)  Owner and, by acceptance of its Equipment Notes of any
  Series, each Note Holder of such Series, hereby agree that no payment or
  distribution shall be made on or in respect of the Secured Obligations
  owed to such Note Holder of such Series, including any payment or
  distribution of cash, property or securities after the commencement of a
  proceeding of the type referred to in Section 4.02(e), except as
  expressly provided in Article III.

            (b)  By the acceptance of its Equipment Notes of any Series
  (other than Series G), each Note Holder of such Series agrees that in the
  event that such Note Holder, in its capacity as a Note Holder, shall
  receive any payment or distribution on any Secured Obligations in respect
  of such Series which it is not entitled to receive under this Section
  2.15 or Article III, it will hold any amount so received in trust for the
  Senior Holder (as defined in Section 2.15(c)) and will forthwith turn
  over such payment to the Indenture Trustee in the form received to be

  and (ii) after the Secured Obligations in respect of Series G Equipment
  Notes have been paid in full, the Note Holders of Series C until the
  Secured Obligations in respect of Series C Equipment Notes have been paid
  in full.

  giving effect to paragraph (i) above, so much of such installment or
  payment remaining as shall be required to pay in full the aggregate
  amount of the payment or payments of Principal Amount and interest and

  amounts then held by the Indenture Trustee as part of the Indenture
  Estate, shall be promptly distributed by the Indenture Trustee in the
  following order of priority:

            First, so much of such payments or amounts as shall be required
  to reimburse the Indenture Trustee for any tax, expense or other loss
  (including, without limitation, all amounts to be expended at the expense
  of, or charged upon the tolls, rents, revenues, issues, products and
  profits of, the property included in the Indenture Estate (all such
  property being herein called the "Mortgaged Property") pursuant to
  Section 4.05(b)) incurred by the Indenture Trustee (to the extent not
  previously reimbursed), the expenses of any sale, taking or other
  proceeding, reasonable attorneys' fees and expenses, court costs, and any
  other expenditures incurred or expenditures or advances made by the
  Indenture Trustee or the Note Holders in the protection, exercise or
  enforcement of any right, power or remedy or any damages sustained by the
  Indenture Trustee or any Note Holder, liquidated or otherwise, upon such
  Event of Default shall be applied by the Indenture Trustee as between
  itself and the Note Holders in reimbursement of such expenses and any
  other expenses for which the Indenture Trustee or the Note Holders are
  entitled to reimbursement under any Operative Document and all amounts
  payable to the other Indenture Indemnitees hereunder and under the
  Participation Agreement excluding those amounts described in clauses

  priority of one over the other, in proportion to the amounts owed each
  hereunder;

            Second, so much of such payments or amounts remaining as shall
  be required to reimburse the then existing or prior Note Holders for
  payments made pursuant to Section 5.03  (to the extent not previously
  reimbursed) shall be distributed to such then existing or prior Note
  Holders ratably, without priority of one over the other, in accordance
  with the amount of the payment or payments made by each such then
  existing or prior Note Holder pursuant to said Section 5.03;

            Third, (i)  so much of such payments or amounts remaining as

  all Series G Equipment Notes, and the accrued but unpaid interest and
  other amounts due thereon and all other Secured Obligations in respect of
  the Series G Equipment Notes to the date of distribution, shall be
  distributed to the Note Holders of Series G, and in case the aggregate
  amount so to be distributed shall be insufficient to pay in full as
  aforesaid, then ratably, without priority of one over the other, in the
  proportion that the aggregate unpaid Principal Amount of all Series G
  Equipment Notes held by each holder plus the accrued but unpaid interest
  and other amounts due hereunder or thereunder to the date of
  distribution, bears to the aggregate unpaid Principal Amount of all
  Series G Equipment Notes held by all such holders plus the accrued but
  unpaid interest and other amounts due thereon to the date of
  distribution; and (ii) after giving effect to paragraph (i) above, so
  much of such payments or amounts remaining as shall be required to pay in
  full the aggregate unpaid Principal Amount of all Series C Equipment
  Notes, and the accrued but unpaid interest and other amounts due thereon
  and all other Secured Obligations in respect of the Series C Equipment
  Notes to the date of distribution, shall be distributed to the Note
  Holders of Series C, and in case the aggregate amount so to be
  distributed shall be insufficient to pay in full as aforesaid, then
  ratably, without priority of one over the other, in the proportion that
  the aggregate unpaid Principal Amount of all Series C Equipment Notes
  held by each holder plus the accrued but unpaid interest and other
  amounts due hereunder or thereunder to the date of distribution, bears to
  the aggregate unpaid Principal Amount of all Series C Equipment Notes
  held by all such holders plus the accrued but unpaid interest and other
  amounts due thereon to the date of distribution;  and

            Fourth, the balance, if any, of such payments or amounts
  remaining thereafter shall be distributed to Owner or as Owner may direct
  free and clear of the Lien of this Indenture.

            No Make-Whole Amount shall be due and payable on the Equipment

            SECTION 3.04.   Certain Payments.

            (a)  Any payments received by the Indenture Trustee for which
  no provision as to the application thereof is made in this Indenture and
  for which such provision is made in the Participation Agreement or any
  other Operative Document shall be applied forthwith to the purpose for
  which such payment was made in accordance with the terms of the
  Participation Agreement or such other Operative Document, as the case may
  be.

            (b)  The Indenture Trustee will distribute promptly upon
  receipt any indemnity payment received by it from Owner in respect of (i)
  the Indenture Trustee in its individual capacity or any other Indenture
  Indemnitees, (ii) any Note Holder, (iii) the Subordination Agent, (iv)
  the Liquidity Provider, (v) the Policy Provider and (vi) the Pass Through
  Trustees, in each case pursuant to Section 6 of the Participation
  Agreement, directly to the Person entitled thereto.  Any payment received
  by the Indenture Trustee the third paragraph of Section 2.02 shall be
  distributed to the Subordination Agent to be distributed in accordance
  with the terms of the Intercreditor Agreement.

            SECTION 3.05.   Other Payments.

            Any payments received by the Indenture Trustee for which no
  provision as to the application thereof is made in the Participation
  Agreement, elsewhere in this Indenture or in any other Operative Document
  shall be distributed by the Indenture Trustee in the manner provided in
  Section 3.03.  Further, and except as otherwise provided in Sections
  3.02, 3.03 and 3.04, all payments received and amounts realized by the
  Indenture Trustee with respect to the Aircraft, to the extent received or
  realized at any time after payment in full of all Secured Obligations due
  the Note Holders, shall be distributed by the Indenture Trustee to Owner.

            SECTION 3.06.   Payments to Owner.

            Any amounts distributed hereunder by the Indenture Trustee to
  Owner shall be paid to Owner (within the time limits contemplated by
  Section 2.04(a)) by wire transfer of funds of the type received by the
  Indenture Trustee at such office and to such account or accounts of such
  entity or entities as shall be designated by notice from Owner to the
  Indenture Trustee from time to time.  Owner hereby notifies the Indenture
  Trustee that unless and until the Indenture Trustee receives notice to
  the contrary from Owner, all amounts to be distributed to Owner pursuant
  to this Indenture shall be distributed by wire transfer of funds of the
  type received by the Indenture Trustee to Owner's account specified in
  Schedule I to the Participation Agreement.

                                 ARTICLE IV

                   CERTAIN COVENANTS OF OWNER; EVENTS OF
                   DEFAULT; REMEDIES OF INDENTURE TRUSTEE

            SECTION 4.01.   Certain Covenants of Owner.

            Owner hereby covenants and agrees that it will duly and
  punctually pay the Principal Amount of, Make-Whole Amount, if any, and
  interest on and other amounts due under the Equipment Notes and hereunder
  in accordance with the terms of the Equipment Notes and this Indenture
  and all amounts, if any, payable by it to the Note Holders under the
  Participation Agreement.

            SECTION 4.02.   Event of Default.

            "Event of Default" means any of the following events (whatever
  the reason for such Event of Default and whether such event shall be
  voluntary or involuntary or come about or be effected by operation of Law
  or pursuant to or in compliance with any judgment, decree or order of any
  court or any order, rule or regulation of any administrative or
  governmental body):

            (a)  the failure of Owner to pay when due any payment of
  Principal Amount of, interest on, Make-Whole Amount, if any, or other
  amount due and payable under any Equipment Note or hereunder and such
  failure shall have continued unremedied for ten (10) Business Days in the
  case of any payment of Principal Amount or interest or Make-Whole Amount,
  if any, thereon and, in the case of any other amount, for ten (10)
  Business Days after Owner receives written demand from the Indenture
  Trustee or any Note Holder; or

            (b)  any representation or warranty made by Owner herein, in
  the Participation Agreement or in any certificate furnished by Owner to
  the Indenture Trustee or any Note Holder in connection with the
  transactions contemplated by the Operative Documents shall prove to have
  been false or incorrect when made in any material respect and continues
  to be material and adverse to the interests of the Indenture Trustee or
  the Note Holders; and if such misrepresentation is capable of being
  corrected and if such correction is being sought diligently, such
  misrepresentation shall not have been corrected within sixty (60) days
  following notice thereof from the Indenture Trustee or any Note Holder to
  Owner; or

            (c)  other than as provided in (d) below, any failure by Owner
  to observe or perform any other covenant or obligation of Owner for the
  benefit of the Indenture Trustee or the Note Holders contained in the
  Participation Agreement, the Equipment Notes or this Indenture which is
  not remedied within a period of sixty (60) days after notice thereof has
  been given to Owner; provided, however, that if Owner shall have
  undertaken to cure any such failure and, notwithstanding the diligence of
  Owner in attempting to cure such failure, such failure is not cured
  within said sixty (60) day period but is curable with future due
  diligence, there shall exist no Event of Default under this Section
  4.02(c) so long as Owner is proceeding with due diligence to cure such
  failure and such failure is remedied not later than three hundred sixty
  (360) days after receipt by Owner of such written notice; or

            (d)  if at any time when the Aircraft is registered under the
  laws of the United States, Owner shall not be a Citizen of the United
  States, and as the result thereof the registration of the Aircraft under
  the Transportation Code, and regulations then applicable thereunder,
  shall cease to be effective; provided that no Event of Default shall be
  deemed to have occurred under this paragraph (d) unless such
  circumstances continue unremedied for more than sixty (60) days after
  Owner has actual knowledge of the state of facts that resulted in such
  ineffectiveness and of such loss of citizenship; or

            (e)  at any time either (i) the commencement of an involuntary
  case or other proceeding in respect of Owner under the federal bankruptcy
  Laws, as now constituted or hereafter amended, or any other applicable
  federal or state bankruptcy, insolvency or other similar Law in the
  United States or seeking the appointment of a receiver, liquidator,
  assignee, custodian, trustee, sequestrator (or similar official) of Owner
  or for all or substantially all of its property, or seeking the winding-
  up or liquidation of its affairs and the continuation of any such case or
  other proceeding undismissed and unstayed for a period of ninety (90)
  consecutive days; or (ii) the commencement by Owner of a voluntary case
  or proceeding under the federal bankruptcy Laws, as now constituted or
  hereafter amended, or any other applicable federal or state bankruptcy,
  insolvency or other similar Law in the United States, or the consent by
  Owner to the appointment of or taking possession by a receiver,
  liquidator, assignee, trustee, custodian, sequestrator (or other similar
  official) of Owner or for all or substantially all of its property, or
  the making by Owner of any assignment for the benefit of creditors or
  Owner shall take any action to authorize any of the foregoing; or

            (f)  Owner shall fail to carry and maintain or with respect to
  the Aircraft (or cause to be carried or maintained) insurance required to
  be maintained in accordance with Section 7.04.

            SECTION 4.03.   [Reserved].

            SECTION 4.04.   Remedies.

            (a)  If an Event of Default shall have occurred and be
  continuing and so long as the same shall continue unremedied, then and in
  every such case the Indenture Trustee may exercise any or all of the
  rights and powers and pursue any and all of the remedies pursuant to this
  Article IV and shall have and may exercise all of the rights and remedies
  of a secured party under the Uniform Commercial Code in effect in the
  State of New York and may take possession of all or any part of the
  properties covered or intended to be covered by the Lien created hereby
  or pursuant hereto and may exclude Owner  and all Persons claiming under
  Owner wholly or partly therefrom; provided, however, that during any
  period the Aircraft is subject to the Civil Reserve Air Fleet Program and
  in possession of the United States Government or an agency or
  instrumentality of the United States, the Indenture Trustee shall not, on
  account of any Event of Default, be entitled to exercise or pursue any of
  the powers, rights or remedies described in this Section 4.04 in such
  manner as to limit Owner's control (or any Lessee's control under any
  Lease) of any Airframe or any Engines installed thereon, unless at least
  sixty (60) days (or such lesser period as may then be applicable under
  the Air Mobility Command program of the United States Government) written
  notice of default hereunder shall have been given by the Indenture
  Trustee by registered or certified mail to Owner (and any Lessee) with a
  copy addressed to the Contracting Office Representative of the Air
  Mobility Command of the United States Air Force under any contract with
  Owner (or any Lessee) relating to the Aircraft; provided further, that
  the Indenture Trustee shall give Owner twenty (20) days' prior written
  notice of its intention to sell the Aircraft.  Without limiting any of
  the foregoing, it is understood and agreed that the Indenture Trustee may
  exercise any right of sale of the Aircraft available to it, even though
  it shall not have taken possession of the Aircraft and shall not have
  possession thereof at the time of such sale.

            (b)  If an Event of Default shall have occurred and be
  continuing, then and in every such case the Indenture Trustee may (and
  shall, upon receipt of a written demand therefor from a Majority in
  Interest of Note Holders), at any time, by delivery of written notice or
  notices to Owner, declare all the Equipment Notes to be due and payable,
  whereupon the unpaid Principal Amount of all Equipment Notes then
  outstanding, together with accrued but unpaid interest thereon (without
  Make-Whole Amount) and other amounts due thereunder, shall immediately
  become due and payable without presentment, demand, protest or notice,
  all of which are hereby waived; provided that if an Event of Default
  referred to in clause (e) of Section 4.02  shall have occurred and be
  continuing, then and in every such case the unpaid Principal Amount then
  outstanding, together with accrued but unpaid interest and all other
  amounts due thereunder and hereunder shall immediately and without
  further act become due and payable without presentment, demand, protest
  or notice, all of which are hereby waived.

                 This Section 4.04(b), however, is subject to the condition
  that, if at any time after the Principal Amount of the Equipment Notes
  shall have become so due and payable, and before any judgment or decree
  for the payment of the money so due, or any thereof, shall be entered,
  all overdue payments of interest upon the Equipment Notes and all other
  amounts payable under the Equipment Notes (except the Principal Amount of
  the Equipment Notes which by such declaration shall have become payable)
  shall have been duly paid, and every other Default and Event of Default
  with respect to any covenant or provision of this Indenture shall have
  been cured, then and in every such case a Majority in Interest of Note
  Holders may (but shall not be obligated to), by written instrument filed
  with the Indenture Trustee, rescind and annul the Indenture Trustee's
  declaration and its consequences; but no such rescission or annulment
  shall extend to or affect any subsequent Default or Event of Default or
  impair any right consequent thereon.

            (c)  Any Note Holder shall be entitled, at any sale pursuant to
  this Section 4.04, to credit against any purchase price bid at such sale
  by such holder all or any part of the unpaid obligations owing to such
  Note Holder and secured by the Lien of this Indenture (but only to the
  extent that such purchase price would have been paid to such Note Holder
  pursuant to Article III if such purchase price were paid in cash and the
  foregoing provisions of this subsection (c) were not given effect).

            (d)  In the event of any sale of the Indenture Estate, or any
  part thereof, pursuant to any judgment or decree of any court or
  otherwise in connection with the enforcement of any of the terms of this
  Indenture, the unpaid Principal Amount of all Equipment Notes then
  outstanding, together with accrued interest thereon, and other amounts
  due thereunder, shall immediately become due and payable without
  presentment, demand, protest or notice, all of which are hereby waived.

            (e)  Notwithstanding anything contained herein, so long as the
  Pass Through Trustee under any Pass Through Trust Agreement or the
  Subordination Agent on its behalf is a Note Holder, the Indenture Trustee
  will not be authorized or empowered to acquire title to any Mortgaged
  Property or take any action with respect to any Mortgaged Property so
  acquired by it if such acquisition or action would cause any Pass Through
  Trust to fail to qualify as a "grantor trust" for federal income tax
  purposes.

            SECTION 4.05.   Return of Aircraft, Etc.

            (a)  If an Event of Default shall have occurred and be
  continuing, at the request of the Indenture Trustee, Owner shall promptly
  execute and deliver to the Indenture Trustee such instruments and other
  documents as the Indenture Trustee may deem necessary or advisable to
  enable the Indenture Trustee or an agent or representative designated by
  the Indenture Trustee, at such time or times and place or places as the
  Indenture Trustee may specify, to obtain possession of all or any part of
  the Mortgaged Property included in the Indenture Estate to which the
  Indenture Trustee shall at the time be entitled hereunder.  If Owner
  shall for any reason fail to execute and deliver such instruments and
  documents after such request by the Indenture Trustee, the Indenture
  Trustee may (i) obtain a judgment conferring on the Indenture Trustee the
  right to immediate possession and requiring Owner to execute and deliver
  such instruments and documents to the Indenture Trustee, to the entry of
  which judgment Owner hereby specifically consents to the fullest extent
  permitted by applicable law, and (ii) pursue all or part of such
  Mortgaged Property wherever it may be found and may enter any of the
  premises of Owner wherever such Mortgaged Property may be or be supposed
  to be and search for such Mortgaged Property and take possession of and
  remove such Mortgaged Property. All expenses of obtaining such judgment
  or of pursuing, searching for and taking such property shall, until paid,
  be secured by the Lien of this Indenture.

            (b)  Upon every such taking of possession, the Indenture
  Trustee may, from time to time, at the expense of the Mortgaged Property,
  make all such expenditures for maintenance, use, operation, storage,
  insurance, leasing, control, management, disposition, modifications or
  alterations to and of the Mortgaged Property, as it may deem proper.  In
  each such case, the Indenture Trustee shall have the right to maintain,
  use, operate, store, insure, lease, control, manage, dispose of, modify
  or alter the Mortgaged Property and to carry on the business and to
  exercise all rights and powers of Owner relating to the Mortgaged
  Property, as the Indenture Trustee shall deem best, including the right
  to enter into any and all such agreements with respect to the
  maintenance, use, operation, storage, insurance, leasing, control,
  management, disposition, modification or alteration of the Mortgaged
  Property or any part thereof as the Indenture Trustee may determine, and
  the Indenture Trustee shall be entitled to collect and receive directly
  all tolls, rents, revenues, issues, income, products and profits of the
  Mortgaged Property and every part thereof.  Such tolls, rents, revenues,
  issues, income, products and profits shall be applied to pay the expenses
  of the maintenance, use, operation, storage, insurance, leasing, control,
  management, disposition, improvement, modification or alteration of the
  Mortgaged Property and of conducting the business thereof, and to make
  all payments which the Indenture Trustee may be required or may elect to
  make, if any, for taxes, assessments, insurance or other proper charges
  upon the Mortgaged Property or any part thereof, and all other payments
  which the Indenture Trustee may be required or authorized to make under
  any provision of this Indenture, as well as just and reasonable
  compensation for the services of the Indenture Trustee, and of all
  Persons properly engaged and employed by the Indenture Trustee with
  respect hereto.

            SECTION 4.06.   Remedies Cumulative.

            Each and every right, power and remedy given to the Indenture
  Trustee specifically or otherwise in this Indenture shall be cumulative
  and shall be in addition to every other right, power and remedy herein
  specifically given or now or hereafter existing at law, in equity or by
  statute, and each and every right, power and remedy whether specifically
  herein given or otherwise existing may be exercised from time to time and
  as often and in such order as may be deemed expedient by the Indenture
  Trustee, 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 Indenture Trustee 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 Owner or to be an acquiescence therein.

            SECTION 4.07.   Discontinuance of Proceedings.

            In case the Indenture Trustee shall have instituted any
  proceeding to enforce any right, power or remedy under this Indenture by
  foreclosure, entry or otherwise, and such proceedings shall have been
  discontinued or abandoned for any reason or shall have been determined
  adversely to the Indenture Trustee, then and in every such case Owner and
  the Indenture Trustee shall, subject to any determination in such
  proceedings, be restored to their former positions and rights hereunder
  with respect to the Mortgaged Property, and all rights, remedies and
  powers of the Indenture Trustee or Owner shall continue as if no such
  proceedings had been instituted.

            SECTION 4.08.   Waiver of Past Defaults.

            Upon written instruction from a Majority in Interest of Note
  Holders, the Indenture Trustee shall waive any past Default hereunder and
  its consequences and upon any such waiver such Default shall cease to
  exist and any Event of Default arising therefrom shall be deemed to have
  been cured for every purpose of this Indenture, but no such waiver shall
  extend to any subsequent or other Default or impair any right consequent
  thereon; provided, that in the absence of written instructions from all
  the Note Holders, the Indenture Trustee shall not waive any Default (i)
  in the payment of the Principal Amount, Make-Whole Amount, if any, and
  interest and other amounts due under any Equipment Note then outstanding,
  or (ii) in respect of a covenant or provision hereof which, under Article
  X, cannot be modified or amended without the consent of each Note Holder.

            SECTION 4.09.   Appointment of Receiver.

            If an Event of Default shall have occurred and be continuing,
  the Indenture Trustee shall, as a matter of right, be entitled to the
  appointment of a receiver (who may be the Indenture Trustee or any
  successor or nominee thereof) for all or any part of the Mortgaged
  Property, whether such receivership be incidental to a proposed sale of
  the Mortgaged Property or the taking of possession thereof or otherwise,
  and Owner hereby consents to the appointment of such a receiver and will
  not oppose any such appointment. Any receiver appointed for all or any
  part of the Mortgaged Property shall be entitled to exercise all the
  rights and powers of the Indenture Trustee with respect to the Mortgaged
  Property.

            SECTION 4.10.   Indenture Trustee Authorized to Execute Bills
  of Sale, Etc.

            Owner irrevocably appoints the Indenture Trustee the true and
  lawful attorney-in-fact of Owner in its name and stead and on its behalf,
  for the purpose, if an Event of Default shall have occurred and be
  continuing, of effectuating in accordance with applicable law any sale,
  assignment, transfer or delivery for the enforcement of the Lien of this
  Indenture, whether pursuant to foreclosure or power of sale, assignments
  and other instruments as may be necessary or appropriate, with full power
  of substitution, Owner hereby ratifying and confirming all that such
  attorney or any substitute shall do by virtue hereof in accordance with
  applicable law.  Nevertheless, if so requested by the Indenture Trustee
  or any purchaser, Owner shall ratify and confirm any such sale,
  assignment, transfer or delivery, by executing and delivering to the
  Indenture Trustee or such purchaser all bills of sale, assignments,

  confirmation as may be designated in any such request.

            SECTION 4.11.   Rights of Note Holders to Receive Payment.

            Notwithstanding any other provision of this Indenture, the
  right of any Note Holder to receive payment of principal of, and Make-
  Whole Amount, if any, and interest on an Equipment Note on or after the
  respective due dates expressed in such Equipment Note, or to bring suit
  for the enforcement of any such payment on or after such respective dates
  in accordance with the terms hereof, shall not be impaired or affected
  without the consent of such Note Holder.

                                 ARTICLE V

                      DUTIES OF THE INDENTURE TRUSTEE

            SECTION 5.01.   Notice of Event of Default.

            If the Indenture Trustee shall have Actual Knowledge of an
  Event of Default or of a Default arising from a failure by Owner to pay
  when due any payment of Principal Amount of, interest on, or Make-Whole
  Amount, if any, due and payable under any Equipment Note, the Indenture
  Trustee shall give prompt written notice thereof to Owner and each Note
  Holder.  Subject to the terms of Sections 4.04, 4.08, 5.02 and 5.03, the
  Indenture Trustee shall take such action, or refrain from taking such
  action, with respect to such Event of Default or Default (including with
  respect to the exercise of any rights or remedies hereunder) as the
  Indenture Trustee shall be instructed in writing by a Majority in
  Interest of Note Holders. Subject to the provisions of Section 5.03, if
  the Indenture Trustee shall not have received instructions as above
  provided within twenty (20) days after mailing notice of such Event of
  Default to the Note Holders, the Indenture Trustee may, subject to
  instructions thereafter received pursuant to the preceding provisions of
  this Section 5.01, take such action, or refrain from taking such action,
  but shall be under no duty to take or refrain from taking any action,
  with respect to such Event of Default or Default as it shall determine
  advisable in the best interests of the Note Holders.

            SECTION 5.02.   Action upon Instructions; Certain Rights and
  Limitations.

            Subject to the terms of Sections 4.04, 4.08, 5.01 and 5.03,
  upon the written instructions at any time and from time to time of a
  Majority in Interest of Note Holders, the Indenture Trustee shall,
  subject to the terms of this Section 5.02, take such of the following
  actions as may be specified in such instructions: (i) give such notice or
  direction or exercise such right, remedy or power hereunder as shall be
  specified in such instructions; and (ii) give such notice or direction or
  exercise such right, remedy or power under the Participation Agreement,
  the Purchase Agreement, or any other part of the Indenture Estate as
  shall be specified in such instructions.

            The Indenture Trustee will execute and Owner will file or cause
  to be filed such continuation statements with respect to financing
  statements relating to the security interest created hereunder in the
  Indenture Estate as specified by Owner pursuant to Section 7(j) of the
  Participation Agreement or as may be specified from time to time in
  written instructions of a Majority in Interest of Note Holders (which
  instructions may, by their terms, be operative only at a future date and
  which shall be accompanied by the form of such continuation statement so
  to be filed). The Indenture Trustee will furnish to each Note Holder,
  promptly upon receipt thereof, duplicates or copies of all reports,
  notices, requests, demands, certificates and other instruments furnished
  to the Indenture Trustee hereunder.

            SECTION 5.03.   Indemnification.

            The Indenture Trustee shall not be required to take any action
  or refrain from taking any action under Sections 5.01 (other than the
  first sentence thereof) or 5.02 or Article IV unless the Indenture
  Trustee shall have been indemnified to its reasonable satisfaction
  against any liability, cost or expense (including counsel fees) which may
  be incurred in connection therewith pursuant to a written agreement with
  one or more Note Holders.  The Indenture Trustee shall not be under any
  obligation to take any action under this Indenture and nothing herein or
  therein shall require the Indenture Trustee to expend or risk its own
  funds or otherwise incur the risk of any financial liability in the
  performance of any of its rights or powers if it shall have reasonable
  grounds for believing that repayment of such funds or adequate indemnity
  against such risk or liability is not reasonably assured to it (the
  written indemnity of any Note Holder who is a QIB, signed by an
  authorized officer thereof, in favor of, delivered to and in form
  reasonably satisfactory to Indenture Trustee shall be accepted as
  reasonable assurance of adequate indemnity).  The Indenture Trustee shall
  not be required to take any action under Section 5.01 (other than the
  first sentence thereof) or 5.02 or Article IV, nor shall any other
  provision of this Indenture or any other Operative Document be deemed to
  impose a duty on the Indenture Trustee to take any action, if the
  Indenture Trustee shall have been advised by counsel that such action is
  contrary to the terms hereof or is otherwise contrary to Law.

            SECTION 5.04.   No Duties Except as Specified in Indenture or
  Instructions.

            The Indenture Trustee shall not have any duty or obligation to
  use, operate, store, lease, control, manage, sell, dispose of or
  otherwise deal with the Aircraft or any other part of the Indenture
  Estate, or to otherwise take or refrain from taking any action under, or
  in connection with, this Indenture or any part of the Indenture Estate,
  except as expressly provided by the terms of this Indenture or as
  expressly provided in written instructions from Note Holders as provided
  in this Indenture; and no implied duties or obligations shall be read
  into this Indenture against the Indenture Trustee.  The Indenture Trustee
  agrees that it will in its individual capacity and at its own cost and
  expense (but without any right of indemnity in respect of any such cost
  or expense under Section 8.01), promptly take such action as may be
  necessary duly to discharge all liens and encumbrances on any part of the
  Indenture Estate which result from claims against it in its individual
  capacity not related to its interest in the Aircraft or the
  administration of the Indenture Estate or any other transaction pursuant
  to this Indenture or any document included in the Indenture Estate.

            SECTION 5.05.   No Action Except Under Indenture or
  Instructions.

            The Indenture Trustee agrees that it will not use, operate,
  store, lease, control, manage, sell, dispose of or otherwise deal with
  the Aircraft or any other part of the Indenture Estate except in
  accordance with the powers granted to, or the authority conferred upon,
  the Indenture Trustee pursuant to this Indenture and in accordance with
  the express terms hereof.

            SECTION 5.06.   Replacement Airframes and Replacement Engines.

            (a)  Event of Loss with Respect to the Aircraft.  Upon the
  occurrence of an Event of Loss with respect to the Airframe or the
  Airframe and the Engines and/or engines then installed thereon, Owner
  shall forthwith (and in any event, within fifteen (15) days after such
  occurrence) give the Indenture Trustee written notice of such Event of
  Loss, and, within sixty (60) days after such Event of Loss, Owner shall
  give the Indenture Trustee written notice of its election to perform one
  of the following options (it being agreed that if Owner shall not have
  given such notice of election within such period, Owner shall be deemed
  to have elected the option set forth in clause (i) below).  Owner may
  elect either to:

                         (i)    redeem the Equipment Notes in the
       manner set forth in Section 2.10 on the earlier of (x) the
       Business Day next succeeding the 120th day following the
       occurrence of such Event of Loss or (y) an earlier Business Day
       irrevocably specified fifteen (15) days in advance by notice
       from Owner to the Indenture Trustee; or

                         (ii)   substitute an aircraft or an airframe
       or an airframe and one or more engines, as the case may be;
       provided that, if Owner does not perform its obligation to
       effect such substitution in accordance with this Section
       5.06(a), during the period of time provided herein, then Owner
       shall redeem the Equipment Notes in the manner set forth in
       Section 2.10 on the Business Day next succeeding the 120th day
       following the occurrence of such Event of Loss.

            In the event Owner shall elect to substitute an aircraft (or an
  airframe or an airframe and one or more engines, as the case may be)
  Owner shall, at its sole expense, not later than the Business Day next
  succeeding the 120th day following the occurrence of such Event of Loss,
  (1) furnish the Indenture Trustee with such evidence as the Indenture
  Trustee may reasonably request that Owner holds title to such aircraft
  (or such airframe or such airframe and one or more engines which,
  together with the Engines constituting a part of the Aircraft but not
  installed thereon at the time of such Event of Loss, constitute the
  Aircraft) free and clear of all Liens (other than Permitted Liens) and
  having a value, utility and remaining useful life at least equal to the
  Aircraft subject to such Event of Loss assuming that the Aircraft had
  been maintained in accordance with the requirements of this Indenture,
  and Owner shall cause an Indenture Supplement to be duly executed by
  Owner and filed for recording pursuant to the Transportation Code, or the
  applicable laws, rules and regulations of any other jurisdiction in which
  the Airframe may then be registered as permitted by Section 7(b) of the
  Participation Agreement with respect to such substituted property, (2)
  cause a financing statement or statements with respect to such
  substituted property to be filed in such place or places, if any, as may
  be deemed necessary or desirable by the Indenture Trustee to perfect the
  Indenture Trustee's interest therein, (3) furnish the Indenture Trustee
  with such evidence of compliance with the insurance provisions hereof
  with respect to such substituted property as the Indenture Trustee may
  reasonably request and (4) furnish the Indenture Trustee with an opinion
  of counsel (which shall be Skadden, Arps, Slate, Meagher & Flom LLP or
  Skadden, Arps, Slate, Meagher & Flom (Illinois) and, if not, other
  counsel chosen by Owner and reasonably acceptable to the Indenture
  Trustee) reasonably satisfactory to the Indenture Trustee to the effect
  that the Indenture Trustee will be entitled to the benefits of Section
  1110 of the Bankruptcy Code with respect to the substitute aircraft,
  provided that such opinion need not be delivered to the extent that
  immediately prior to such substitution the benefits of Section 1110 of
  the Bankruptcy Code were not, solely by reason of a change in law or
  governmental interpretation thereof after the date hereof, available to
  the Indenture Trustee with respect to the Aircraft.  For all purposes
  hereof, the property so substituted shall be deemed part of the property
  subject to the Lien of this Indenture and shall be deemed an "Aircraft",
  "Airframe" and "Engine", as the case may be, as defined herein.

            (b)  Event of Loss with Respect to an Engine.  Upon the
  occurrence of an Event of Loss with respect to an Engine under
  circumstances in which there has not occurred an Event of Loss with
  respect to the Airframe, Owner shall forthwith (and in any event, within
  fifteen (15) days after such occurrence) give the Indenture Trustee
  written notice thereof and shall, within one hundred twenty (120) days
  after the occurrence of such Event of Loss, (i) cause an Indenture
  Supplement to be duly executed by Owner and to be filed for recording
  pursuant to the Transportation Code, or the applicable laws, rules and
  regulations of any other jurisdiction in which the Airframe may then be
  registered as permitted by Section 7(b) of the Participation Agreement
  with respect to an Acceptable Alternate Engine and, (ii) furnish the
  Indenture Trustee with such evidence of compliance with the insurance
  provisions hereof with respect to such replacement engine as the
  Indenture Trustee  may reasonably request.  For all purposes hereof, each
  such replacement engine shall, after such designation, be deemed part of
  the property subject to the Lien of this Indenture hereunder, and shall
  be deemed an "Engine".

            (c)  Requisition for Use of an Engine by the United States
  Government or the Government of Registry of the Aircraft.  In the event
  of the requisition for use of an Engine by the United States Government
  or any other government of registry of the Aircraft or any agency or
  instrumentality of any thereof, Owner shall replace such Engine hereunder
  by complying (or causing any Lessee to comply) with the terms of Section
  5.06(b) to the same extent as if an Event of Loss had occurred with
  respect thereto, and, upon compliance with Section 5.06(b), any payments
  received by Owner from such government with respect to such requisition
  shall be paid over to, or retained by, Owner.

            (d)  Application of Payments During Existence of Event of
  Default.  Any amount referred to in this Section 5.06 which is payable to
  or retainable by Owner shall not be paid to or retained by Owner if at
  the time of such payment or retention an Event of Default has occurred
  and is continuing, but shall be held by or paid over to the Indenture
  Trustee as security for the obligations of Owner hereunder and, if an
  Event of Default has occurred and is continuing hereunder, applied
  against Owner's obligations hereunder as and when due.  At such time as
  there shall not be continuing any such Event of Default, such amount
  shall be paid to Owner to the extent not previously applied in accordance
  with the preceding sentence.

            SECTION 5.07.   Indenture Supplements for Replacements.

            If a Replacement Airframe or Replacement Engine is being
  substituted as contemplated by Section 5.06, Owner and the Indenture
  Trustee agree for the benefit of the Note Holders and Owner, subject to
  fulfillment of the conditions precedent and compliance by Owner with the
  requirements of Section 5.06 with respect to such Replacement Airframe or
  Replacement Engine, to execute and deliver an Indenture Supplement.

            SECTION 5.08.   Effect of Replacement.

            In the event of the substitution of an Airframe or of an Engine
  or Engines pursuant to Section 5.06, (a) all provisions of this Indenture
  relating to the Airframe or Engine or Engines being replaced shall be
  applicable to such Replacement Airframe or Replacement Engine or Engines
  with the same force and effect as if such Replacement Airframe or
  Replacement Engine or Engines were the same airframe or engine or
  engines, as the case may be, as the Airframe or Engine or Engines being
  replaced but for the Event of Loss with respect to the Airframe or Engine
  or Engines being replaced, and (b) the provisions of this Indenture shall
  no longer be applicable to the Airframe or Engine or Engines being
  replaced, which shall be released from the Lien of this Indenture.

            SECTION 5.09.   Investment of Amounts Held by Indenture
  Trustee.

            Any amounts held by the Indenture Trustee pursuant to any
  provision of any other Operative Document providing for amounts to be
  held by the Indenture Trustee which are not distributed pursuant to the
  other provisions of Article III shall be invested by the Indenture
  Trustee from time to time in Cash Equivalents as directed by Owner so
  long as the Indenture Trustee may acquire the same using its best
  efforts.  Unless otherwise expressly provided in this Indenture, any
  income realized as a result of any such investment, net of the Indenture
  Trustee's reasonable fees and expenses in making such investment, shall
  be held and applied by the Indenture Trustee in the same manner as the
  principal amount of such investment is to be applied and any losses, net
  of earnings and such reasonable fees and expenses, shall be charged
  against the principal amount invested.  The Indenture Trustee shall not
  be liable for any loss resulting from any investment required to be made
  by it under this Indenture other than by reason of its willful misconduct
  or gross negligence, and any such investment may be sold (without regard
  to its maturity) by the Indenture Trustee without instructions whenever
  such sale is necessary to make a distribution required by this Indenture.

                                 ARTICLE VI

                           THE INDENTURE TRUSTEE

  applicable to it and agrees to perform the same but only upon the terms
  of this Indenture and agrees to receive and disburse all monies
  constituting part of the Indenture Estate in accordance with the terms
  hereof.  The Indenture Trustee, in its individual capacity, shall not be
  answerable or accountable under any circumstances, except (i) for willful
  misconduct or gross negligence (other than for the handling of funds, for
  which the standard of accountability shall be willful misconduct or
  negligence), (ii) as provided in the fourth sentence of Section 2.04(a)
  and the last sentence of Section 5.04, and (iii) for liabilities that may
  result from the inaccuracy of any representation or warranty of the
  Indenture Trustee (in its individual capacity) in the Participation
  Agreement or expressly made hereunder.

            SECTION 6.02.   Absence of Duties.

            Except in accordance with written instructions furnished
  pursuant to Section 5.01 or 5.02 , and except as provided in, and without
  limiting the generality of, Sections 5.03 and 5.04, the Indenture Trustee
  shall have no duty (i) to see to any registration of the Aircraft or any
  recording or filing of this Indenture or any other document, or to see to
  the maintenance of any such registration, recording or filing,  (ii) to
  see to any insurance on the Aircraft or to effect or maintain any such
  insurance, whether or not Owner shall be in default with respect thereto,
  (iii) to see to the payment or discharge of any lien or encumbrance of
  any kind against any part of the Indenture Estate, or (iv) to inspect the
  Aircraft at any time or ascertain or inquire as to the performance or
  observance of any of Owner's covenants hereunder with respect to the
  Aircraft.

            SECTION 6.03.   No Representations or Warranties as to Aircraft
  or Documents.

            THE INDENTURE TRUSTEE IN ITS INDIVIDUAL OR TRUST CAPACITY  DOES
  NOT MAKE AND SHALL NOT BE DEEMED TO HAVE MADE AND HEREBY EXPRESSLY
  DISCLAIMS ANY REPRESENTATION OR WARRANTY, EXPRESS OR IMPLIED, AS TO THE
  TITLE, AIRWORTHINESS, VALUE, COMPLIANCE WITH SPECIFICATIONS, CONDITION,
  DESIGN, QUALITY, DURABILITY, OPERATION, MERCHANTABILITY OR FITNESS FOR
  USE FOR A PARTICULAR PURPOSE OF THE AIRCRAFT OR ANY ENGINE, AS TO THE
  ABSENCE OF LATENT OR OTHER DEFECTS, WHETHER OR NOT DISCOVERABLE, AS TO
  THE ABSENCE OF ANY INFRINGEMENT OF ANY PATENT, TRADEMARK OR COPYRIGHT, AS
  TO THE ABSENCE OF OBLIGATIONS BASED ON STRICT LIABILITY IN TORT OR ANY
  OTHER REPRESENTATION OR WARRANTY WHATSOEVER.  The Indenture Trustee, in
  its individual or trust capacity, does not make and shall not be deemed
  to have made any representation or warranty as to the validity, legality
  or enforceability of this Indenture, the Participation Agreement, the
  Equipment Notes, the Purchase Agreement, the Purchase Agreement
  Assignment or the Consent and Agreement, or as to the correctness of any
  statement contained in any thereof.

            SECTION 6.04.   No Segregation of Monies; No Interest.

            Any monies paid to or retained by the Indenture Trustee
  pursuant to any provision hereof and not then required to be distributed
  to the Note Holders or Owner as provided in Article III need not be
  segregated in any manner except to the extent required by Law and Section
  5.09, and may be deposited under such general conditions as may be
  prescribed by Law, and the Indenture Trustee shall not be liable for any
  interest thereon (except that the Indenture Trustee shall invest all
  monies held as directed by Owner so long as no Event of Default has
  occurred and is continuing (or in the absence of such direction, by the
  Majority In Interest of Note Holders) in Cash Equivalents; provided,
  however, that any payments received, or applied hereunder, by the
  Indenture Trustee shall be accounted for by the Indenture Trustee so that
  any portion thereof paid or applied pursuant hereto shall be identifiable
  as to the source thereof.

            SECTION 6.05.   Reliance; Agreements; Advice of Counsel.

            The Indenture Trustee shall not incur any liability to anyone
  in acting upon any signature, instrument, notice, resolution, request,
  consent, order, certificate, report, opinion, bond or other document or
  paper believed by it to be genuine and believed by it to be signed by the
  proper party or parties.  The Indenture Trustee may accept a copy of a
  resolution of the Board of Directors of any party to the Participation
  Agreement, certified by the Secretary or an Assistant Secretary thereof
  as duly adopted and in full force and effect, as conclusive evidence that
  such resolution has been duly adopted and that the same is in full force
  and effect.  As to the aggregate unpaid Principal Amount of Equipment
  Notes outstanding as of any date, Owner may for all purposes hereof rely
  on a certificate signed by any Vice President or other authorized
  corporate trust officer of the Indenture Trustee.  As to any fact or
  matter relating to Owner the manner of ascertainment of which is not
  specifically described herein, the Indenture Trustee may for all purposes
  hereof rely on a certificate, signed by a duly authorized officer of
  Owner, as to such fact or matter, and such certificate shall constitute
  full protection to the Indenture Trustee for any action taken or omitted
  to be taken by it in good faith in reliance thereon.  In the
  administration of the trusts hereunder, the Indenture Trustee may execute
  any of the trusts or powers hereof and perform its powers and duties
  hereunder directly or through agents or attorneys and may at the expense
  of the Indenture Estate, consult with counsel, accountants and other
  skilled persons to be selected and retained by it, and the Indenture
  Trustee shall not be liable for anything done, suffered or omitted in
  good faith by it in accordance with the advice or opinion of any such
  counsel, accountants or other skilled persons.

            SECTION 6.06.   [Reserved].

            SECTION 6.07.   Compensation.

            The Indenture Trustee shall be entitled to reasonable
  compensation, including expenses and disbursements (including the
  reasonable fees and expenses of counsel), for all services rendered
  hereunder and shall, on and subsequent to an Event of Default hereunder,
  have a priority claim on the Indenture Estate for the payment of such
  compensation, to the extent that such compensation shall not be paid by
  Owner, and shall have the right, on and subsequent to an Event of Default
  hereunder, to use or apply any monies held by it hereunder in the
  Indenture Estate toward such payments.  The Indenture Trustee agrees that
  it shall have no right against the Loan Participants or the Note Holders
  for any fee as compensation for its services as trustee under this
  Indenture.

            SECTION 6.08.   Instructions from Note Holders.

            In the administration of the trusts created hereunder, the

  Majority in Interest of Note Holders should any provision of this
  Indenture appear to conflict with any other provision herein or should
  the Indenture Trustee's duties or obligations hereunder be unclear, and
  the Indenture Trustee shall incur no liability in refraining from acting
  until it receives such instructions.  The Indenture Trustee shall be
  fully protected for acting in accordance with any instructions received

  materialmen's, mechanics', workmen's, repairmen's, employees' or other
  like Liens arising in the ordinary course of Owner's (or, if a Lease is

  promptly, at its own expense, take (or cause to be taken) such actions as
  may be necessary duly to discharge any such Lien not excepted above if
  the same shall arise at any time.

            SECTION 7.02.   Registration, Maintenance and Operation;

       at its own cost and expense, shall (or shall cause any Lessee
       to): (A) cause the Aircraft to be duly registered in the name

       airworthiness certification for the Aircraft to be maintained
       in good standing at all times (other than during temporary
       periods of storage or during maintenance or modification
       permitted hereunder) under the Transportation Code, except when
       all of Owner's Airbus Model A330 aircraft powered by engines of
       the same type as those with which the Airframe shall be
       equipped at the time of such grounding and registered in the
       United States have been grounded by the FAA (although such
       certification need actually be maintained only during such
       periods as the Aircraft is registered in the United States), or
       the applicable laws of any other jurisdiction in which the
       Aircraft may then be registered from time to time in accordance
       with Section 7(b) of the Participation Agreement, utilizing,
       except during any period that a Lease is in effect, the same
       manner and standard of maintenance, service, repair or overhaul
       used by Owner with respect to similar aircraft operated by
       Owner in similar circumstances and utilizing, during any period
       that a Lease is in effect, the same manner and standard of
       maintenance, service, repair or overhaul used by the Lessee
       with respect to similar aircraft operated by the Lessee in
       similar circumstances; and (C) maintain or cause to be
       maintained in English all records, logs and other materials
       required to be maintained in respect of the Aircraft by the FAA
       or the applicable regulatory agency or body of any other
       jurisdiction in which the Aircraft may then be registered.

                         (ii)   Operation.  Owner will not maintain,
       use, service, repair, overhaul or operate the Aircraft (or
       permit any Lessee to maintain, use, service, repair, overhaul
       or operate the Aircraft) in violation of any law or any rule,
       regulation, order or certificate of any government or
       governmental authority (domestic or foreign) having
       jurisdiction over the Aircraft, or in violation of any
       airworthiness certificate, license or registration relating to
       the Aircraft issued by any such authority, except to the extent
       Owner (or, if a Lease is then in effect, any Lessee) is
       contesting in good faith the validity or application of any
       such law, rule, regulation or order in any reasonable manner
       which does not involve any material risk of sale, forfeiture or
       loss of the Aircraft.  Owner will not operate the Aircraft, or
       permit any Lessee to operate the Aircraft, in any area excluded
       from coverage by any insurance required by the terms of Section
       7.04; provided, however, that the failure of Owner to comply
       with the provisions of this sentence shall not give rise to an
       Event of Default hereunder if indemnification complying with
       Section 7.04 has been provided or where such failure is
       attributable to extraordinary circumstances involving an
       isolated occurrence or series of incidents not in the ordinary
       course of the regular operations of Owner (or any Lessee) such
       as a hijacking, medical emergency, equipment malfunction,
       weather condition, navigational error or other causes beyond
       the reasonable control of Owner (or any Lessee).

            (b)  Possession and Leases.  Owner will not, without the prior
  written consent of the Indenture Trustee, lease or otherwise in any
  manner deliver, transfer or relinquish possession of the Airframe or any
  Engine or install or permit any Engine to be installed on any airframe
  other than the Airframe or enter into any Wet Lease, and so long as Owner
  (or any Lessee) shall comply with the provisions of Section 7.02(a) and
  Section 7.04, Owner may (or may permit any Lessee to), without the prior
  written consent of the Indenture Trustee:

                         (i)    subject the Airframe and the Engines
       or engines then installed thereon to interchange agreements or
       any Engine to pooling or similar arrangements, in each case
       customary in the airline industry and entered into by Owner
       (or, if a Lease is then in effect, by Lessee) in the ordinary
       course of its business; provided that (A) no such agreement or
       arrangement contemplates or requires the transfer of title to
       the Airframe, (B) if Owner's title to any Engine shall be
       divested under any such agreement or arrangement, such
       divestiture shall be deemed to be an Event of Loss with respect
       to such Engine and Owner shall (or shall cause Lessee to)
       comply with Section 5.06(b) in respect thereof, and (C) any
       interchange agreement to which the Airframe may be subject
       shall be with a U.S. Air Carrier or a Foreign Air Carrier.

                         (ii)   deliver possession of the Airframe or
       any Engine to the manufacturer thereof (or for delivery
       thereto) or to any organization (or for delivery thereto) for
       testing, service, repair, maintenance or overhaul work on the
       Airframe or Engine or any part of any thereof or for
       alterations or modifications in or additions to such Airframe
       or Engine to the extent required or permitted by the terms of
       Section 7.03;

                         (iii)  install an Engine on an airframe owned
       by Owner (or any Lessee) free and clear of all Liens, except:
       (A) Permitted Liens and those which apply only to the engines
       (other than Engines), appliances, parts, instruments,
       appurtenances, accessories, furnishings and other equipment
       (other than Parts) installed on such airframe (but not to the
       airframe as an entirety), (B) the rights of third parties under
       interchange agreements or pooling or similar arrangements which
       would be permitted under clause (i) above, provided that
       Owner's title to such Engine and the first priority Lien of the
       Indenture shall not be divested or impaired as a result thereof
       and (C) mortgage liens or other security interests, provided
       that (as regards this clause (C)) the documents creating such
       mortgage liens or other security interests (or, if applicable,
       another written agreement governing such mortgage liens or
       other security interests) effectively provide that such Engine
       shall not become subject to the lien of such mortgage or
       security interest, notwithstanding the installation thereof on
       such airframe;

                         (iv)   install an Engine on an airframe
       leased to Owner (or any Lessee) or purchased by Owner (or any
       Lessee) subject to a conditional sale or other security
       agreement, provided that (x) such airframe is free and clear of
       all Liens, except: (A) the rights of the parties to the lease
       or conditional sale or other security agreement covering such
       airframe, or their assignees, and (B) Liens of the type
       permitted by clause (iii) of this paragraph (b) and (y) such
       lease, conditional sale or other security agreement effectively
       provides that such Engine shall not become subject to the lien
       of such lease, conditional sale or other security agreement,
       notwithstanding the installation thereof on such airframe;

                         (v)    install an Engine on an airframe owned
       by Owner (or any Lessee), leased to Owner (or any Lessee) or
       purchased by Owner (or any Lessee) subject to a conditional
       sale or other security agreement under circumstances where
       neither clause (iii) nor clause (iv) of this paragraph (b) is
       applicable, provided that such installation shall be deemed an
       Event of Loss with respect to such Engine and Owner shall (or
       shall cause any Lessee to) comply with Section 5.06(b) in
       respect thereof;

                         (vi)   to the extent permitted by this
       Section 7.02(b), subject any appliances, Parts or other
       equipment removed from the Airframe or any Engine to any
       pooling arrangement referred to in this Section 7.02(b);

                         (vii)  subject (or permit any Lessee to
       subject) the Airframe or any Engine to the Civil Reserve Air
       Fleet Program and transfer (or permit any Lessee to transfer)
       possession of the Airframe or any Engine to the United States
       Government or any instrumentality or agency thereof pursuant to
       the Civil Reserve Air Fleet Program, so long as Owner (or any
       Lessee) shall (A) promptly notify the Indenture Trustee upon
       subjecting the Airframe or any Engine to the Civil Reserve Air
       Fleet Program in any contract year and provide the Indenture
       Trustee with the name and address of the Contracting Office
       Representative for the Air Mobility Command of the United
       States Air Force to whom notice must be given pursuant to
       Section 4.04(a), and (B) promptly notify the Indenture Trustee
       upon transferring possession of the Airframe or any Engine to
       the United States of America or any agency or instrumentality
       thereof pursuant to such program;

                         (viii) enter into a Wet Lease for the
       Airframe and Engines or engines then installed thereon with any
       third party;

                         (ix)   transfer possession of the Airframe or
       any Engine to the United States Government or any
       instrumentality or agency thereof pursuant to a contract, a
       copy of which shall be provided to the Indenture Trustee; or

                         (x)    at any time, in Owner's sole
       discretion, enter into any lease with respect to the Aircraft,
       Airframe or any Engine to any Permitted Lessee that is not then
       subject to any bankruptcy, insolvency, liquidation,
       reorganization, dissolution or similar proceeding and shall not
       have substantially all of its property in the possession of any
       liquidator, trustee, receiver or similar person;  provided,
       however, with respect to a lease to a Permitted Lessee not
       domiciled in the United States, Owner shall deliver to the
       Indenture Trustee an opinion of counsel to the effect that (I)
       the terms of the lease constitute valid and binding obligations
       of the Lessee and (subject to customary bankruptcy and
       equitable remedies exceptions and to other similar exceptions
       customary in such opinions) enforceable against Lessee (it
       being understood that such opinion may be an opinion as to the
       form of the lease only and may assume due authorization,
       execution, delivery, requisite approvals and absence of
       conflicts with laws, contracts or organizational documents)
       under the laws of the jurisdiction governing the lease and (II)
       unless Owner shall have agreed to provide insurance covering
       the risk of requisition of use of the Aircraft by the
       government of the jurisdiction of the proposed Lessee, that the
       laws of such jurisdiction require fair compensation by the
       government of such jurisdiction payable in currency freely
       convertible into Dollars for the loss of use of the Aircraft in
       the event of the requisition by such government of such use;
       and provided, further, that, with respect to any lease to any
       Affiliate of Owner, (I) such Lessee shall be a Certificated Air
       Carrier and (II) Owner shall deliver to the Indenture Trustee
       an opinion of counsel to the effect that Owner would be
       entitled to the benefits of Section 1110 of the Bankruptcy Code
       with respect to the Aircraft if such Affiliate were to be a
       debtor in a case under Chapter 11 of the Bankruptcy Code, such
       opinion to be subject to customary assumptions and
       qualifications.  Owner shall provide the Indenture Trustee with
       a copy of any sublease which has a term of more than one (1)
       year.

            The rights of any Lessee or other transferee who receives
  possession by reason of a transfer permitted by this paragraph (b) (other
  than the transfer of an Engine which is deemed an Event of Loss) shall be
  subject and subordinate to, and any Lease permitted by this paragraph (b)
  shall be expressly subject and subordinate to the Indenture Trustee's
  rights to repossess and to void such Lease upon such repossession, and
  Owner shall remain primarily liable hereunder for the performance of all
  of the terms of this Indenture and the terms of any such Lease shall not
  permit any Lessee to take any action not permitted to be taken by Owner
  hereunder with respect to the Aircraft.  No pooling agreement, lease,
  sublease or other relinquishment of possession of the Airframe or any
  Engine or Wet Lease shall in any way discharge or diminish any of Owner's
  obligations hereunder or constitute a waiver of the Indenture Trustee's
  rights or remedies hereunder.  The Indenture Trustee agrees, for the
  benefit of Owner (and any Lessee) and for the benefit of any mortgagee or
  other holder of a security interest in any engine (other than an Engine)
  owned by Owner (or any Lessee), any lessor of any engine (other than an
  Engine) leased to Owner (or any Lessee) and any conditional vendor of any
  engine (other than an Engine) purchased by Owner (or any Lessee) subject
  to a conditional sale agreement or any other security agreement, that no
  interest shall be created hereunder in any engine so owned, leased or
  purchased and that none of the Indenture Trustee, its successors or
  assigns will acquire or claim, as against Owner (or any Lessee) or any
  such mortgagee, lessor or conditional vendor or other holder of a
  security interest or any successor or assignee of any thereof, any right,
  title or interest in such engine as the result of such engine being
  installed on the Airframe.

            Any Wet Lease or similar arrangement under which Owner
  maintains operational control of the Aircraft shall not constitute a
  delivery, transfer or relinquishment of possession of the Aircraft for
  purposes of this Section.

            The Indenture Trustee acknowledges that any consolidation or
  merger of Owner or conveyance, transfer or lease of all or substantially
  all of Owner's assets otherwise permitted by the Operative Documents
  shall not be prohibited by this Section.

            (c)  Insignia.  On or prior to the Delivery Date, or as soon as
  practicable thereafter, Owner agrees to affix and maintain (or cause to
  be affixed and maintained), at its expense, in the cockpit of the
  Airframe adjacent to the airworthiness certificate therein and on each
  Engine a nameplate bearing the inscription:

                                Mortgaged To

            State Street Bank and Trust Company of Connecticut,
                           National Association,
                            as Indenture Trustee

  (such nameplate to be replaced, if necessary, with a nameplate reflecting
  the name of any successor Indenture Trustee, as permitted under the
  Operative Documents).  Except as above provided, Owner will not allow the
  name of any Person (other than Owner) to be placed on the Airframe or on
  any Engine as a designation that might be interpreted as a claim of
  ownership; provided that nothing herein contained shall prohibit Owner
  (or any Lessee) from placing its customary colors and insignia on the
  Airframe or any Engine.

            SECTION 7.03.   Replacement and Pooling of Parts; Alterations,
  Modifications and Additions.

            (a)  Replacement of Parts.  Owner, at its own cost and expense,
  will promptly replace or cause to be replaced all Parts which may from
  time to time be incorporated or installed in or attached to the Airframe
  or any Engine and which may from time to time become worn out, lost,
  stolen, destroyed, seized, confiscated, damaged beyond repair or
  permanently rendered unfit for use for any reason whatsoever, except as
  otherwise provided in paragraph (c) of this Section 7.03 or if the
  Airframe or an Engine to which a Part relates has suffered an Event of
  Loss.  In addition, Owner (or any Lessee) may, at its own cost and
  expense, remove in the ordinary course of maintenance, service, repair,
  overhaul or testing, any Parts, whether or not worn out, lost, stolen,
  destroyed, seized, confiscated, damaged beyond repair or permanently
  rendered unfit for use, provided that Owner (or any Lessee), except as
  otherwise provided in paragraph (c) of this Section 7.03, will, at its
  own cost and expense, replace such Parts as promptly as practicable.  All
  replacement Parts shall be free and clear of all Liens (except for
  Permitted Liens and pooling arrangements to the extent permitted by
  paragraph (b) of this Section 7.03 and except in the case of replacement
  property temporarily installed on an emergency basis) and shall be in as
  good operating condition as, and shall have a value and utility at least
  equal to, the Parts replaced assuming such replaced Parts were in the
  condition and repair required to be maintained by the terms hereof.
  Except as otherwise provided in paragraph (c) of this Section 7.03, all
  Parts at any time removed from the Airframe or any Engine shall remain
  the property of Owner, no matter where located.  Immediately upon any
  replacement part becoming incorporated or installed in or attached to the
  Airframe or any Engine as above provided, without further act (subject
  only to Permitted Liens and any pooling arrangement to the extent
  permitted by paragraph (b) of this Section 7.03 and except in the case of
  replacement property temporarily installed on an emergency basis), such
  replacement Part shall become subject to the Lien of this Indenture and
  be deemed part of the Airframe or such Engine for all purposes hereof to
  the same extent as the Parts originally incorporated or installed in or
  attached to the Airframe or such Engine, and the replaced Part shall be
  free and clear of the Lien of this Indenture and shall no longer be
  deemed a Part hereunder.

            (b)  Pooling of Parts.  Any Part removed from the Airframe or
  any Engine as provided in paragraph (a) of this Section 7.03 may be
  subjected by Owner (or any Lessee) to a normal pooling arrangement
  customary in the airline industry of which Owner (or, if a Lease is then
  in effect, any Lessee) is a party entered into in the ordinary course of
  Owner's (or any Lessee's) business; provided that the Part replacing such
  removed Part shall be incorporated or installed in or attached to such
  Airframe or Engine in accordance with such paragraph (a) as promptly as
  practicable after the removal of such removed Part.  In addition, any
  replacement Part when incorporated or installed in or attached to the
  Airframe or any Engine in accordance with such paragraph (a) may be owned
  by any third party subject to such a normal pooling arrangement, provided
  that Owner (or any Lessee), at its expense, as promptly thereafter as
  practicable, either (i) causes title to such replacement Part to vest in
  Owner in accordance with such paragraph (a) free and clear of all Liens
  except Permitted Liens (other than pooling arrangements) or (ii) replaces
  such replacement Part by incorporating or installing in or attaching to
  the Airframe or Engine a further replacement Part owned by Owner (or any
  Lessee) free and clear of all Liens except Permitted Liens (other than
  pooling arrangements) and by causing title to such further replacement
  Part to vest in Owner in accordance with such paragraph (a).

            (c)  Alterations, Modifications and Additions.  Owner, at its
  own expense, will make (or cause to be made) such alterations and
  modifications in and additions to the Airframe and Engines as may be
  required from time to time to meet the applicable standards of the FAA or
  any applicable regulatory agency or body of any other jurisdiction in
  which the Aircraft may then be registered as permitted by Section 7(b) of
  the Participation Agreement; provided, however, that Owner (or, if a
  Lease is then in effect, any Lessee) may, in good faith, contest the
  validity or application of any such law, rule, regulation or order in any
  reasonable manner which does not adversely affect the Indenture Trustee.
  In addition, Owner (or any Lessee), at its own expense, may from time to
  time add further parts or accessories and make such alterations and
  modifications in and additions to the Airframe or any Engine as Owner (or
  any Lessee) may deem desirable in the proper conduct of its business,
  including, without limitation, removal of Parts which Owner (or any
  Lessee) has determined in its reasonable judgment to be obsolete or no
  longer suitable or appropriate for use on the Airframe or such Engine
  (such parts, "Obsolete Parts"); provided that no such alteration,
  modification or addition shall materially diminish the value, utility or
  remaining useful life of the Airframe or such Engine below the value,
  utility or remaining useful life thereof immediately prior to such
  alteration, modification or addition, assuming the Airframe or such
  Engine was then in the condition required to be maintained by the terms
  of this Indenture, except that the value (but not the utility or
  remaining useful life) of the Airframe or any Engine may be reduced by
  the value of Obsolete Parts which shall have been removed so long as the
  aggregate value of all Obsolete Parts which shall have been removed and
  not replaced shall not exceed $750,000 in aggregate value at the time of
  removal.  Owner (or any Lessee) may remove or suffer to be removed any
  Part incorporated or installed in or attached or added to the Airframe or
  an Engine as the result of any such alteration, modification or addition,
  provided that such additional Part (i) is in addition to, and not in
  replacement of or substitution for, any Part originally incorporated or
  installed in or attached to the Airframe or any Engine at the time of
  delivery thereof hereunder or any Part in replacement of, or substitution
  for, any such Part, (ii) is not required to be incorporated or installed
  in or attached or added to the Airframe or any Engine pursuant to the
  terms of Section 7.02 or the first sentence of this paragraph (c) and
  (iii) can be removed from the Airframe or such Engine without diminishing
  or impairing the value, utility or remaining useful life which the
  Airframe or such Engine would have had at the time of removal had such
  alteration, modification or addition not occurred.

            Upon the removal by Owner (or Lessee) of any Part as provided
  above, such Part shall no longer be deemed part of the Airframe or Engine
  from which it was removed.

            (d)  Certain Matters Regarding Passenger Convenience Equipment.
  Owner may install on the Airframe, subject to the requirements of Section
  7.03(c) above, Passenger Convenience Equipment that is (i) owned by
  another Person and leased to Owner, (ii) sold to Owner by another Person
  subject to a conditional sale contract or other retained security
  interest, (iii) leased to Owner pursuant to a lease which is subject to a
  security interest in favor of another Person or (iv) installed on the
  Aircraft subject to a license granted to Owner by another Person, and in
  any such case  the Indenture Trustee will not acquire or claim, as
  against any such other Person, any right, title or interest in any such
  Passenger Convenience Equipment solely as a result of its installation on
  the Airframe.  Owner agrees that if any such Person repossesses such
  Passenger Convenience Equipment, Owner will (or cause such Person to)
  restore the Aircraft to the condition it would have been in had the
  installation of such Passenger Convenience Equipment not occurred.

            SECTION 7.04.   Insurance.

            (a)  Owner's Obligation to Insure.  Owner shall comply with, or
  cause to be complied with, each of the provisions of Exhibit B, which
  provisions are hereby incorporated by this reference as if set forth in
  full herein.

            (b)  [Reserved.]

            (c)  Indemnification by Government in Lieu of Insurance.
  Notwithstanding any provisions of this Section 7.04 requiring insurance,
  the Indenture Trustee agrees to accept, in lieu of insurance against any
  risk with respect to the Aircraft, indemnification from, or insurance
  provided by, the United States Government or any agency or
  instrumentality thereof, or, upon the written consent of the Indenture
  Trustee, other government of registry of the Aircraft or agency or
  instrumentality thereof, against such risk in an amount which, when added
  to the amount of insurance against such risk maintained by Owner (or any
  Lessee) shall be at least equal to the amount of insurance against such
  risk otherwise required by this Section 7.04 (taking into account self-
  insurance permitted by Exhibit B hereto).

            (d)  Application of Payments During Existence of an Event of
  Default. Any amount referred to in paragraph (b) of Exhibit B which is
  payable to or retainable by Owner (or any Lessee) shall not be paid to or
  retained by Owner (or any Lessee) if at the time of such payment or
  retention an Event of Default shall have occurred and be continuing, but
  shall be held by or paid over to the Indenture Trustee as security for
  the obligations of Owner hereunder if the Indenture Trustee declares this
  Indenture to be in default pursuant to Section 4.02, applied against
  Owner's obligations hereunder as and when due.  At such time as there
  shall not be continuing any such Event of Default, such amount shall be
  paid to Owner to the extent not previously applied in accordance with the
  preceding sentence.

            SECTION 7.05.   Inspection.

            At all reasonable times and upon at least 15 days' prior
  written notice to Owner, the Indenture Trustee, or its authorized
  representatives, may inspect the Aircraft and inspect and make copies of
  the books and records of Owner and any Lessee required to be maintained
  by the FAA or the regulatory agency or body of another jurisdiction in
  which the Aircraft is then registered relating to the maintenance of the
  Aircraft (at the Indenture Trustee's risk and expense) and shall keep any
  information or copies obtained thereby confidential and shall not
  disclose the same to any Person, except (A) to the Note Holders and to
  prospective and permitted transferees of the Note Holders' or the
  Indenture Trustee's interest (and such prospective and permitted
  transferee's counsel, independent insurance advisors or other agents) who
  agree to hold such information confidential, (B) to the Note Holders' or
  the Indenture Trustee's counsel, independent insurance advisors or other
  agents who agree to hold such information confidential, or (C) as may be
  required by any statute, court or administrative order or decree or
  governmental ruling or regulation, provided, however, that any and all
  disclosures permitted by clause (C) above shall be made only to the
  extent necessary to meet the specific requirements or needs of the
  Persons for whom such disclosures are hereby permitted.  Any such
  inspection of the Aircraft shall be subject to Owner's safety and
  security rules applicable to the location of the Aircraft, shall be a
  visual, walk-around inspection of the interior and exterior of the
  Aircraft and shall not include opening any panels, bays or the like
  without the express consent of Owner (except in connection with a heavy
  maintenance visit when a panel, bay or the like is scheduled or required
  to be opened), which consent Owner may in its sole discretion withhold;
  provided that no exercise of such inspection right shall interfere with
  the normal operation or maintenance of the Aircraft by, or the business
  of, Owner (or any Lessee).  The Indenture Trustee shall not have any duty
  to make any such inspection nor shall it incur any liability or
  obligation by reason of not making such inspection.  Except during the
  continuance of an Event of Default, all inspections by the Indenture
  Trustee and its authorized representatives provided for under this
  Section 7.05 shall be limited to one (1) inspection of any kind
  contemplated by this Section 7.05 during any calendar year.

            SECTION 7.06.   Filings; Delivery of Financial Statements.

             Forthwith upon the execution and delivery of each Indenture
  Supplement from time to time required by the terms hereof and upon
  execution and delivery of any amendment to this Indenture, Owner will
  cause such Indenture Supplement (and, in the case of the initial
  Indenture Supplement and the Indenture as well) or amendment to be duly
  filed and recorded, and maintained of record, in accordance with the
  applicable laws of the government of registry of the Aircraft.  Owner
  agrees to furnish to the Indenture Trustee promptly after execution and
  delivery of any supplement and amendment hereto (except for any such
  supplement or amendment which does not require or receive the approval of
  Owner pursuant to the Operative Documents and is not required pursuant to
  the terms of the Operative Documents), an opinion of counsel (which may
  be Owner's General Counsel, Deputy General Counsel, Associate General
  Counsel or Assistant General Counsel) reasonably satisfactory to the
  Indenture Trustee as to the due recording or filing of such supplement or
  amendment.  Owner will deliver to the Indenture Trustee (a) within sixty
  (60) days after the end of each of the first three quarterly periods of

  shall have the right at its option at any time, on at least thirty (30)
  days prior written notice, to terminate the Lien of the Indenture with
  respect to any Engine.  In such event, and prior to the date of such
  termination, Owner shall replace such Engine hereunder by complying with
  the terms of Section 5.06 to the same extent as if an Event of Loss had
  occurred with respect to such Engine.

            SECTION 7.08.   No Set-Off, Counterclaim, etc.  Except as
  expressly provided herein, Owner's obligation to pay all amounts payable

  against the Indenture Trustee (in its individual capacity or as Indenture
  Trustee), any Loan Participant, or anyone else for any reason whatsoever
  (whether in connection with the transactions contemplated hereby or any
  other transactions), including, without limitation, any breach by Owner
  of its warranties, agreements or covenants contained in any of the
  Operative Documents, (ii) any defect in the title, registration,
  airworthiness, condition, design, operation, or fitness for use of, or
  any damage to or loss or destruction of, the Aircraft, or any

                                ARTICLE VIII

               INDEMNIFICATION OF INDENTURE TRUSTEE BY OWNER

            SECTION 8.01.   Scope of Indemnification.

            Owner hereby agrees, except as otherwise provided in Section
  2.04(b), to assume liability for, and does hereby indemnify, protect,
  save and keep harmless the Indenture Trustee (in its individual and trust
  capacities), and its successors, assigns, agents and servants, from and
  against any and all liabilities, obligations, losses, damages, penalties,
  taxes (excluding any taxes payable by the Indenture Trustee on or
  measured by any compensation received by the Indenture Trustee for its
  services under this Indenture), claims, actions, suits, costs, expenses
  or disbursements (including reasonable legal fees and expenses) of any
  kind and nature whatsoever, which may be imposed on, incurred by or
  asserted against the Indenture Trustee (whether or not also indemnified
  against by any other Person under any other document) in any way relating
  to or arising out of this Indenture or any other Operative Document to
  which it is a party or the enforcement of any of the terms of any
  thereof, or in any way relating to or arising out of the manufacture,
  purchase, acceptance, non-acceptance, rejection, ownership, delivery,
  lease, possession, use, operation, condition, sale, return or other
  disposition of the Aircraft or any Engine (including, without limitation,
  latent or other defects, whether or not discoverable, and any claim for
  patent, trademark or copyright infringement), or in any way relating to
  or arising out of the administration of the Indenture Estate or the
  action or inaction of the Indenture Trustee hereunder.  Notwithstanding
  the foregoing, the Indenture Trustee shall not be entitled to any
  indemnification for any Expenses to the extent relating to or arising
  from the willful misconduct or gross negligence (or negligence in the
  case of handling funds) of the Indenture Trustee in the performance of
  its duties hereunder or resulting from the inaccuracy of any
  representation or warranty of the Indenture Trustee (in its individual
  capacity) referred to in Section 6.03, or as provided in Section 6.01 or
  in the last sentence of Section 5.04, or as otherwise excluded by the
  terms of Section 6(b) of the Participation Agreement from Owner's
  indemnities under such Section.  In addition, if necessary, the Indenture
  Trustee shall be entitled to indemnification from the Indenture Estate
  for any liability, obligation, loss, damage, penalty, claim, action,
  suit, cost, expense or disbursement indemnified against pursuant to this
  Section 8.01 to the extent not reimbursed by Owner or others, but without
  releasing any of them from their respective agreements of reimbursement;
  and to secure the same the Indenture Trustee shall have a prior Lien on
  the Indenture Estate.  Owner shall be subrogated to the Indenture
  Trustee's rights, if any, to payment from Owner for amounts payable by
  Owner under this Section 8.01.

                                 ARTICLE IX

                      SUCCESSOR AND SEPARATE TRUSTEES

            SECTION 9.01.   [Reserved.]

            SECTION 9.02.   Resignation of Indenture Trustee; Appointment
  of Successor.

            (a)  The Indenture Trustee or any successor thereto may resign
  at any time without cause by giving at least 30 days' prior written
  notice to Owner and each Note Holder, such resignation to be effective
  upon the acceptance of the trusteeship by a successor Indenture Trustee.
  In addition, a Majority in Interest of Note Holders may at any time (but
  only with the consent of Owner, which consent shall not be unreasonably
  withheld, except that such consent shall not be necessary if an Event of
  Default shall have occurred and be continuing) remove the Indenture
  Trustee without cause by an instrument in writing delivered to Owner and
  the Indenture Trustee, and the Indenture Trustee shall promptly notify
  each Note Holder thereof in writing, such removal to be effective upon
  the acceptance of the trusteeship by a successor Indenture Trustee.  In
  the case of the resignation or removal of the Indenture Trustee, a
  Majority in Interest of Note Holders may appoint a successor Indenture
  Trustee by an instrument signed by such holders, which successor, so long
  as no Event of Default shall have occurred and be continuing, shall be
  subject to Owner's reasonable approval.  If a successor Indenture Trustee
  shall not have been appointed within 30 days after such notice of
  resignation or removal, the Indenture Trustee, Owner or any Note Holder
  may apply to any court of competent jurisdiction to appoint a successor
  Indenture Trustee to act until such time, if any, as a successor shall
  have been appointed as above provided.  The successor Indenture Trustee
  so appointed by such court shall immediately and without further act be
  superseded by any successor Indenture Trustee appointed as above
  provided.

            (b)  Any successor Indenture Trustee, however appointed, shall
  execute and deliver to the predecessor Indenture Trustee and Owner an
  instrument accepting such appointment and assuming the obligations of the
  Indenture Trustee hereunder and under the Participation Agreement arising
  from and after the time of such appointment, and thereupon such successor
  Indenture Trustee, without further act, shall become vested with all the
  estates, properties, rights, powers and duties of the predecessor
  Indenture Trustee hereunder in the trust hereunder applicable to it with
  like effect as if originally named the Indenture Trustee herein; but
  nevertheless upon the written request of such successor Indenture
  Trustee, such predecessor Indenture Trustee shall execute and deliver an
  instrument transferring to such successor Indenture Trustee, upon the
  trusts herein expressed applicable to it, all the estates, properties,
  rights and powers of such predecessor Indenture Trustee, and such
  predecessor Indenture Trustee shall duly assign, transfer, deliver and
  pay over to such successor Indenture Trustee all monies or other property
  then held by such predecessor Indenture Trustee hereunder.

            (c)  Any successor Indenture Trustee, however appointed, shall
  be a bank or trust company having its principal place of business in the
  United States and having (or whose obligations under the Operative
  Documents are guaranteed by an affiliated entity having) a combined
  capital and surplus of at least $100,000,000, if there be such an
  institution willing, able and legally qualified to perform the duties of
  the Indenture Trustee hereunder upon reasonable or customary terms.

            (d)  Any corporation into which the Indenture 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 Indenture Trustee shall be a party, or any corporation to which
  substantially all the corporate trust business of the Indenture Trustee
  may be transferred, shall, subject to the terms of paragraph (c) of this
  Section 9.02, be a successor Indenture Trustee and the Indenture Trustee
  under this Indenture without further act.

            SECTION 9.03.   Appointment of Additional and Separate
  Trustees.

            (a)  Whenever (i) the Indenture Trustee shall deem it necessary
  or desirable in order to conform to any law of any jurisdiction in which
  all or any part of the Indenture Estate shall be situated or to make any
  claim or bring any suit with respect to or in connection with the
  Indenture Estate, this Indenture, any other Indenture Agreement, the
  Equipment Notes or any of the transactions contemplated by the
  Participation Agreement, (ii) the Indenture Trustee shall be advised by
  counsel satisfactory to it that it is so necessary or prudent in the
  interests of the Note Holders (and the Indenture Trustee shall so advise
  Owner), or (iii) the Indenture Trustee shall have been requested to do so
  by a Majority in Interest of Note Holders, then in any such case, the
  Indenture Trustee and, upon the written request of the Indenture Trustee,
  Owner, shall execute and deliver an indenture supplemental hereto and
  such other instruments as may from time to time be necessary or advisable
  either (1) to constitute one or more bank or trust companies or one or
  more Persons approved by the Indenture Trustee, either to act jointly
  with the Indenture Trustee as additional trustee or trustees of all or
  any part of the Indenture Estate, or to act as separate trustee or
  trustees of all or any part of the Indenture Estate, in each case with
  such rights, powers, duties and obligations consistent with this
  Indenture as may be provided in such supplemental indenture or other
  instruments as the Indenture Trustee or a Majority in Interest of Note
  Holders may deem necessary or advisable, or (2) to clarify, add to or
  subtract from the rights, powers, duties and obligations theretofore
  granted any such additional and separate trustee, subject in each case to
  the remaining provisions of this Section 9.03.  If Owner shall not have
  taken any action requested of it under this Section 9.03(a) that is
  permitted or required by its terms within 15 days after the receipt of a
  written request from the Indenture Trustee so to do, or if an Event of
  Default shall have occurred and be continuing, the Indenture Trustee may
  act under the foregoing provisions of this Section 9.03(a) without the
  concurrence of Owner; and Owner hereby irrevocably appoints (which
  appointment is coupled with an interest) the Indenture Trustee, its agent
  and attorney-in-fact to act for it under the foregoing provisions of this
  Section 9.03(a) in either of such contingencies.  The Indenture Trustee
  may, in such capacity, execute, deliver and perform any such supplemental
  indenture, or any such instrument, as may be required for the appointment
  of any such additional or separate trustee or for the clarification of,
  addition to or subtraction from the rights, powers, duties or obligations
  theretofore granted to any such additional or separate trustee.  In case
  any additional or separate trustee appointed under this Section 9.03(a)
  shall die, become incapable of acting, resign or be removed, all the
  assets, property, rights, powers, trusts, duties and obligations of such
  additional or separate trustee shall revert to the Indenture Trustee
  until a successor additional or separate trustee is appointed as provided
  in this Section 9.03(a).

            (b)  No additional or separate trustee shall be entitled to
  exercise any of the rights, powers, duties and obligations conferred upon
  the Indenture Trustee in respect of the custody, investment and payment
  of monies and all monies received by any such additional or separate
  trustee from or constituting part of the Indenture Estate or otherwise
  payable under any Operative Document to the Indenture Trustee shall be
  promptly paid over by it to the Indenture Trustee.  All other rights,
  powers, duties and obligations conferred or imposed upon any additional
  or separate trustee shall be exercised or performed by the Indenture
  Trustee and such additional or separate trustee jointly except to the
  extent that applicable law of any jurisdiction in which any particular
  act is to be performed renders the Indenture Trustee incompetent or
  unqualified to perform such act, in which event such rights, powers,
  duties and obligations (including the holding of title to all or part of
  the Indenture Estate in any such jurisdiction) shall be exercised and
  performed by such additional or separate trustee.  No additional or
  separate trustee shall take any discretionary action except on the
  instructions of the Indenture Trustee or a Majority in Interest of Note
  Holders.  No trustee hereunder shall be personally liable by reason of
  any act or omission of any other trustee hereunder, except that the
  Indenture Trustee shall be liable for the consequences of its lack of
  reasonable care in selecting, and Indenture Trustee's own actions in
  acting with, any additional or separate trustee.  Each additional or
  separate trustee appointed pursuant to this Section 9.03 shall be subject
  to, and shall have the benefit of Articles IV through IX and Article XI
  insofar as they apply to the Indenture Trustee.  The powers of any
  additional or separate trustee appointed pursuant to this Section 9.03
  shall not in any case exceed those of the Indenture Trustee hereunder.

            (c)  If at any time the Indenture Trustee shall deem it no
  longer necessary or desirable in order to conform to any such law or take
  any such action or shall be advised by such counsel that it is no longer
  so necessary or desirable in the interest of the Note Holders, or in the
  event that the Indenture Trustee shall have been requested to do so in
  writing by a Majority in Interest of Note Holders, the Indenture Trustee
  and, upon the written request of the Indenture Trustee, Owner, shall
  execute and deliver an indenture supplemental hereto and all other
  instruments and agreements necessary or proper to remove any additional
  or separate trustee.  The Indenture Trustee may act on behalf of Owner
  under this Section 9.03(c) when and to the extent it could so act under
  Section 9.03(a).

  modification or consent, as may be specified in such request and as may
  be (in the case of any such amendment, supplement or modification), to

  Trustee may enter into one or more agreements supplemental hereto without
  the consent of any Note Holder for any of the following purposes: (i) (a)

            SECTION 10.02.  Trustees Protected.

            If, in the opinion of the institution acting as Indenture
  Trustee hereunder, any document required to be executed by it pursuant to
  the terms of Section 10.01  adversely affects any right, duty, immunity
  or indemnity with respect to such institution under this Indenture, such
  institution may in its discretion decline to execute such document.

  Trustee shall mail, by first class mail, postage prepaid, a copy thereof
  to Owner and to each Note Holder at its address last set forth in the

                                 EXHIBIT B
                                     TO
                      INDENTURE AND SECURITY AGREEMENT



                                 INSURANCE

       The portion of this Exhibit appearing below this text will be
  intentionally deleted from the FAA filing counterpart as the parties
  hereto deem it to contain confidential information.

            (a)  Public Liability and Property Damage Insurance.  (1)
  Except as provided in clause (2) of this subsection (a), and subject to
  self-insurance to the extent permitted by subsection (d) of this Exhibit
  B, Owner will carry or cause to be carried with respect to the Aircraft
  at its or any Lessee's expense (i) comprehensive airline liability
  (including, without limitation, passenger, contractual, bodily injury and
  property damage liability) insurance (exclusive of manufacturer's product
  liability insurance) and (ii) cargo liability insurance, (A) in an amount
  not less than the greater of (x) the amounts of comprehensive airline
  liability insurance from time to time applicable to aircraft owned or
  leased, and operated by Owner (or, if a Lease is then in effect, by
  Lessee) of the same type as the Aircraft and (y) $300 million per
  occurrence, (B) of the type and covering the same risks as from time to
  time applicable to aircraft owned or leased and operated by Owner of the
  same type as the Aircraft, and (C) which is maintained in effect with
  insurers of nationally or internationally recognized reputation and
  responsibility; provided, however, that Owner need not maintain such
  cargo liability insurance, or may maintain such cargo liability insurance
  in an amount less than $300 million per occurrence, so long as the amount
  of cargo liability insurance, if any, maintained with respect to the
  Aircraft is not less than the cargo liability insurance, if any,
  maintained for other Airbus Model A330 aircraft owned or leased and
  operated by Owner.

            (2) During any period that the Airframe or an Engine, as the
  case may be, is on the ground and not in operation, Owner may carry or
  cause to be carried as to such non-operating property, in lieu of the
  insurance required by clause (1) above, and subject to the self-insurance
  to the extent permitted by subsection (d), insurance by insurers of
  nationally or internationally recognized reputation and responsibility
  otherwise conforming with the provisions of said clause (1) except that
  (A) the amounts of coverage shall not be required to exceed the amounts
  of comprehensive airline liability from time to time applicable to
  property owned or leased by Owner of the same type as such non-operating
  property and which is on the ground and not in operation; and (B) the
  scope of the risks covered and the type of insurance shall be the same as
  from time to time shall be applicable to aircraft owned or leased by
  Owner of the same type as such non-operating property and which is on the
  ground and not in operation.

            (b)  Insurance Against Loss or Damage to the Aircraft.
  (1) Except as provided in clause (2) of this subsection (b), and subject
  to the provisions of subsection (d) of this Exhibit B permitting the
  self-insurance, Owner shall maintain or cause to be maintained in effect,
  at its or any Lessee's expense, with insurers of nationally or
  internationally recognized responsibility, all-risk aircraft hull
  insurance covering the Aircraft and fire and extended coverage and all-
  risk aircraft hull insurance covering Engines and Parts while temporarily
  removed from the Aircraft and not replaced by similar components;
  provided that such insurance shall at all times while the Aircraft is
  subject to the Lien of the Indenture be for an amount (taking into
  account the self-insurance to the extent permitted by subsection (d) of
  this Exhibit B) not less than the amount payable under Section 5.06(a)
  upon the occurrence of an Event of Loss; provided further, that, subject
  to compliance with subsection (d) of this Exhibit B, such all-risk
  property damage insurance covering Engines and Parts temporarily removed
  from an Airframe or an airframe or (in the case of Parts) an Engine need
  be obtained only to the extent available at reasonable cost (as
  reasonably determined by Owner).  In the case of a loss with respect to
  an engine (other than an Engine) installed on the airframe in
  circumstances which do not constitute an Event of Loss with respect to
  the Airframe, the Indenture Trustee shall promptly remit any payment made
  to it of any insurance proceeds in respect of such loss to Owner or any
  other third party that is entitled to receive such proceeds.

            Unless an Event of Default has occurred and is continuing, all
  losses will be adjusted by Owner with the insurers.  As between the
  Indenture Trustee and Owner, it is agreed that all insurance payments
  received as the result of the occurrence of an Event of Loss will be
  applied as follows:

                 (x)    if such payments are received with respect to the
            Airframe (or the Airframe and the Engines installed thereon),
            (i) unless such property is replaced pursuant to the last
            paragraph of Section 5.06(a), so much of such payments
            remaining, after reimbursement of the Indenture Trustee for
            reasonable costs and expenses, as shall not exceed the amounts
            payable pursuant to Section 5.06(a), shall be paid over to, or
            retained by, the Indenture Trustee for the benefit of the Note
            Holders (but not in excess of the amounts then due and payable
            under the Equipment Notes); or (ii) if such property is
            replaced pursuant to the last paragraph of Section 5.06(a),
            such payments shall be paid over to, or retained by, Owner (or
            if directed by Owner, any Lessee), provided that Owner shall
            have fully performed or, concurrently therewith, will fully
            perform the terms of the last paragraph of Section 5.06(a) with
            respect to the Event of Loss for which such payments are made;
            and

                 (y)  if such payments are received with respect to an
            Engine under the circumstances contemplated by Section 5.06(b),
            so much of such payments remaining after reimbursement of the
            Indenture Trustee for reasonable costs and expenses, shall be
            paid over to, or retained by, Owner (or if directed by Owner,
            any Lessee), provided that Owner shall have fully performed or
            concurrently therewith will fully perform the terms of Section
            5.06(b) with respect to the Event of Loss for which such
            payments are made.

            As between the Indenture Trustee and Owner, the insurance
  payments for any property damage loss to the Airframe or any engine not
  constituting an Event of Loss with respect thereto will be applied in
  payment for repairs or for replacement property in accordance with the
  terms of Sections 7.02 and 7.03, if not already paid for by Owner (or any
  Lessee), and any balance (or if already paid for by Owner (or any
  Lessee), all such insurance proceeds) remaining after compliance with
  such Sections with respect to such loss shall be paid to Owner (or any
  Lessee if directed by Owner).

            (2)  During any period that the Aircraft is on the ground and
  not in operation, Owner may carry or cause to be carried, in lieu of the
  insurance required by clause (1) above, and subject to self-insurance to
  the extent permitted by subsection (d) of this Exhibit B, insurance
  otherwise conforming with the provisions of said clause (1) except that
  the scope of the risks and the type of insurance shall be the same as
  from time to time applicable to aircraft owned or leased by Owner (or, if
  a Lease is then in effect, by Lessee) of the same type as the Aircraft
  similarly on the ground and not in operation, provided that, subject to
  self-insurance to the extent permitted by subsection (d) of this Exhibit
  B, Owner shall maintain insurance against risk of loss or damage to the
  Aircraft in an amount at least equal to the amount payable upon the
  occurrence of an Event of Loss pursuant to Section 5.06(a) during such
  period that the Aircraft is on the ground and not in operation.

            (3)  If Owner (or any Lessee) shall at any time operate or
  propose to operate the Aircraft, Airframe or any Engine (i) in any area
  of recognized hostilities or (ii) on international routes, and war-risk,
  hijacking or allied perils insurance is maintained by Owner (or any
  Lessee) with respect to other aircraft owned and operated by Owner (or
  any Lessee) on such routes or in such areas, Owner shall maintain or
  cause to be maintained war-risk, hijacking and related perils insurance
  of substantially the same type carried by major United States commercial
  air carriers operating the same or comparable models of aircraft on
  similar routes or in such areas and in no event in an amount less than
  the amount payable upon the occurrence of an Event of Loss pursuant to
  Section 5.06(a).

            (c)  Reports, etc.  Owner will furnish, or cause to be
  furnished, to  the Indenture Trustee and the Pass Through Trustee, on or
  before the Delivery Date and on each annual anniversary date of Owner's
  applicable insurance, a report, signed by Owner's regular insurance
  broker or any other independent firm of insurance brokers reasonably
  acceptable to the Indenture Trustee which brokers may be in the regular
  employ of Owner (the "Insurance Brokers"), describing in reasonable
  detail the hull and liability insurance (and property insurance for
  detached engines and parts) then carried and maintained with respect to
  the Aircraft and stating the opinion of such firm that the insurance
  complies with the terms hereof; provided, that all information contained
  in the foregoing report shall not be made available by the Indenture
  Trustee or the Pass Through Trustee to anyone except (i) to prospective
  and permitted transferees of the Indenture Trustee's or the Pass Through
  Trustee's interest or their respective counsel, independent certified
  public accountants and independent insurance brokers or other agents, who
  agree to hold such information confidential, (ii) the Indenture Trustee's
  or the Pass Through Trustee's counsel or independent certified public
  accountants, independent insurance brokers or agents who agree to hold
  such information confidential or (iii) as may be required by any statute,
  court or administrative order or decree or governmental ruling or
  regulation; provided, however that any disclosure permitted by clause
  (iii) above shall be made only to the extent necessary to meet the
  specific requirements or needs of the Persons to whom such disclosures
  are hereby permitted.  Owner will cause such Insurance Brokers to agree
  to advise the Indenture and the Pass Through Trustee in writing of any
  act or omission on the part of Owner of which it has knowledge and which
  might invalidate or render unenforceable, in whole or in part, any
  insurance on the Aircraft and to advise in writing at least thirty (30)
  days (ten (10) days in the case of war risk, allied perils coverage and
  with respect to the Electronic Date Recognition Exclusion Limited
  Coverage Endorsement), prior to the cancellation or material adverse
  change of any insurance maintained pursuant to Section 7.04, provided
  that if the notice period specified above is not reasonably obtainable,
  the Insurance Broker shall provide for as long a period of prior notice
  as shall then be reasonably obtainable.  In addition, Owner will also
  cause such Insurance Brokers to deliver to the Indenture Trustee and the
  Pass Through Trustee, on or prior to the date of expiration of any
  insurance policy referenced in a previously delivered certificate of
  insurance, a new certificate of insurance, substantially in the same form
  as delivered by Owner to such parties on the Delivery Date except for
  such changes in the report or the coverage consistent with the terms
  hereof.  In the event that Owner or any Lessee shall fail to maintain or
  cause to be maintained insurance as herein provided, the Indenture
  Trustee may at its sole option, but shall be under no duty to, provide
  such insurance and, in such event, Owner shall, upon demand, reimburse
  the Indenture Trustee for the cost thereof to the Indenture Trustee.

            (d)  Self-Insurance. Owner may self-insure by way of
  deductible, premium adjustment or franchise provisions or otherwise
  (including, with respect to insurance maintained pursuant to subsection
  (b) of this Exhibit B, insuring for an amount that is less than the
  amounts payable upon the occurrence of an Event of Loss pursuant to
  Section 5.06(a)) the risks required to be insured against pursuant to
  Section 7.04 under a program applicable to all aircraft (whether owned or
  leased) in Owner's fleet, but in no case shall the aggregate amount of
  self-insurance in regard to subsection (a) and (b) of this Exhibit B
  exceed for any policy year, with respect to all of the aircraft (whether
  owned or leased) in Owner's fleet (including, without limitation, the
  Aircraft), the lesser of (i) 50% of the highest replacement value of any
  single aircraft in Owner's fleet or (ii) 1-1/2% of the average aggregate
  insurable value (during the preceding policy year) of all aircraft
  (including, without limitation, the Aircraft) on which Owner carries
  insurance, unless an insurance broker of national standing shall certify
  that the standard among all other major United States airlines is a
  higher level of self-insurance, in which case Owner may insure the
  Aircraft to such higher level.  In addition to the foregoing right to
  self-insure, Owner (and any Lessee) may self-insure to the extent of any
  applicable mandatory minimum per aircraft (or, if applicable, per annum
  or other period) hull or liability insurance deductible customary in the
  airline industry imposed by the aircraft hull or liability insurer.

            (e)  Terms of Policies.  Any policies of insurance carried in
  accordance with subsection (a) or (b) of this Exhibit B and any policies
  taken out in substitution or replacement for any of such policies (A)
  shall be amended to name the Additional Insureds as their respective
  interests may appear, (B) may provide for the self-insurance to the
  extent permitted in subsection (d) of this Exhibit B, (C) shall provide
  that if the insurers cancel such insurance for any reason whatever or if
  any material change is made in such insurance which adversely affects the
  interest of the Additional Insureds, or such insurance shall lapse for
  non-payment of premium, such cancellation, lapse or change shall not be
  effective as to the Additional Insureds for thirty (30) days (ten (10)
  days in the case of war risk, allied perils coverage and with respect to
  the Electronic Date Recognition Limited Coverage Endorsement) after
  issuance to the Additional Insureds, respectively, of written notice by
  such insurers of such cancellation, lapse or change; provided, however,
  that if any notice period specified above is not reasonably obtainable,
  such policies shall provide for as long a period of prior notice as shall
  then be reasonably obtainable, (D) shall provide that in respect of the
  respective interests of the Additional Insureds in such policies the
  insurance shall not be invalidated by any action or inaction of Owner
  (or, if any Lease is then in effect, any Lessee) or any other Person and
  shall insure the Additional Insureds regardless of any breach or
  violation of any warranty, declaration or condition contained in such
  policies by Owner (or, if any Lease is then in effect, any Lessee), (E)
  shall be primary without right of contribution from any other insurance
  which is carried by any Additional Insured, (F) shall expressly provide
  that all of the provisions thereof, except the limits of liability, shall
  operate in the same manner as if there were a separate policy covering
  each insured, (G) shall waive any right of the insurers to any set-off or
  counterclaim or any other deduction, whether by attachment or otherwise,
  in respect of any liability of any Additional Insured to the extent of
  any moneys due to any Additional Insured, and (H) shall provide that (i)
  in the event of a loss involving proceeds in excess of $5,000,000, the
  proceeds in respect of such loss up to an amount equal to the amount
  payable upon the occurrence of an Event of Loss pursuant to Section
  5.06(a) shall be payable to the Indenture Trustee (so long as the
  Indenture shall not have been discharged) in the manner set forth in
  Sections 2.10 and 2.12 (except in the case of a loss with respect to an
  Engine installed on an airframe other than the Airframe, in which case
  Owner (or any Lessee) shall arrange for any payment of insurance proceeds
  in respect of such loss to be held for the account of the Indenture
  Trustee (so long as the Indenture shall not have been discharged) whether
  such payment is made to Owner (or any Lessee) or any third party), it
  being understood and agreed that in the case of any payment to the
  Indenture Trustee otherwise than in respect of an Event of Loss, the
  Indenture Trustee shall, upon receipt of evidence satisfactory to it that
  the damage giving rise to such payment shall have been repaired or that
  such payment shall then be required to pay for repairs then being made,
  pay the amount of such payment (and all earnings thereon) to Owner or its
  order, and (ii) the entire amount of any loss involving proceeds of
  $5,000,000 or less or the amount of any proceeds of any loss in excess of
  the amount payable upon the occurrence of an Event of Loss pursuant to
  Section 5.06(a) shall be paid to Owner or its order unless an Event of
  Default shall have occurred and be continuing and the insurers have been
  notified thereof by the Indenture Trustee.

      priority security interest and mortgage in, to and under (i) all of
      the Assignor's right, title and interest in and to (x) Clauses 12, 13
      and 17 of the Purchase Agreement (the "Assigned Rights") and (y) the
      Consent and Guaranty (insofar as such Consent and Guaranty relates to
      the Assigned Rights), as and to the extent that the same relates to
      the Aircraft, except to the extent reserved below, including, without
      limitation, in such assignment to Assignee (A) all claims for damages

      and 17 of the Purchase Agreement and the Consent and Guaranty in

           (b)  Assignment of Rights.  If and so long as there shall not

 continuing, so long as  Assignor remains in possession of the Aircraft,
 Assignee hereby authorizes Assignor, to the exclusion of Assignee, to
 exercise in Assignor's name all rights and powers related to the Assigned
 Rights and to retain any recovery or benefit resulting from the enforcement
 of any of the Assigned Rights in respect of the Aircraft, except that
 Assignor may not enter into any change order or other amendment,
 modification or supplement to the Purchase Agreement without the written
 consent or countersignature of Assignee if such change order, amendment,
 modification or supplement would result in any rescission, cancellation or
 termination of the Assigned Rights in respect of the Aircraft or in any way
 limit the rights assigned hereunder.

           (c)  Acceptance of Assignment.  Subject to the terms hereof,
 Assignee accepts the assignment contained in this Clause 2.

           (d)  Onward Transfer of Rights.  Assignee agrees that it may not
 sell, assign or otherwise transfer any of the Assigned Rights without the
 prior written consent of AVSA.

           (e)  Requirement of Notice to AVSA.  For all purposes of this
 Assignment, AVSA shall not be deemed to have knowledge of and need not
 recognize any Event of Default, unless and until AVSA shall have received
 written notice thereof from Assignee addressed to its Chief Executive
 Officer, 2, Rond Point Maurice Bellonte, 31700 Blagnac, France (telex
 521155F) (fax:  011-33-5-6130-4011) and, in acting in accordance with the
 terms of the Purchase Agreement and this Assignment, AVSA may act with
 acquittance and conclusively rely upon any such notice.

 3.   Certain Rights and Obligations of the Parties.  (a) Assignor Remains
      Liable.  It is expressly agreed that, anything herein contained to the
      contrary notwithstanding:  (a) Assignor shall at all times remain
      liable to AVSA under the Purchase Agreement to perform all the duties
      and obligations of the "Buyer" thereunder to the same extent as if
      this Assignment had not been executed; (b) the exercise by Assignee of
      any of the rights assigned hereunder shall not release Assignor from
      any of its duties or obligations to AVSA under the Purchase Agreement
      except to the extent that such exercise by Assignee shall constitute
      performance of such duties and obligations; and (c) except as provided
      in the next succeeding paragraph, neither Assignee nor any Loan
      Participant shall have any obligation or liability under the Purchase
      Agreement by reason of, or arising out of, this Assignment or be
      obligated to perform any of the obligations or duties of Assignor
      under the Purchase Agreement or to make any payment or to make any
      inquiry as to the sufficiency of any payment received by any of them
      or to present or file any claim or to take any other action to collect
      or enforce any claim for any payment assigned hereunder.

           (b)  Assignee Bound by Purchase Agreement.  Without in any way
 releasing Assignor from any of its duties or obligations under the Purchase
 Agreement, Assignee confirms for the benefit of AVSA that, insofar as the
 provisions of the Purchase Agreement relate to the Aircraft, in exercising
 any rights under the Purchase Agreement, or in making any claim with
 respect to the Aircraft or other goods and services delivered or to be
 delivered pursuant to the Purchase Agreement, the terms and conditions of
 the Purchase Agreement disclosed to Assignee in writing shall apply to, and
 be binding upon, Assignee to the extent of its respective interests
 assigned hereunder to the same extent as Assignor.

           (c)  Limit of Effect of this Assignment.  Nothing contained
 herein shall (i) subject AVSA or the Guarantor to any liability to which it
 would not otherwise be subject under the Purchase Agreement or (ii) modify
 in any respect the contractual rights of AVSA or the Guarantor thereunder
 (except, in each case, as provided in the attached Consents and
 Agreements).

           (d)  Appointment as Attorney-in-Fact.  Assignor does hereby
 constitute, effective at any time after an Event of Default shall have
 occurred and be continuing, Assignee and its successors and permitted
 assigns to be Assignor's true and lawful attorney, irrevocably, with full
 power (in the name of Assignor or otherwise) to ask, require, demand,
 receive, compound and give acquittance for any and all monies and claims
 for monies due and to become due under, or arising out of, the Purchase
 Agreement and the Consent and Guaranty in respect of the Aircraft, to the
 extent that the same have been assigned as provided in this Assignment and,
 for such period as Assignee, its successors and assigns may exercise rights
 with respect thereto under this Assignment, to endorse any checks or other
 instruments or orders in connection therewith and to file any claims or
 take any action or institute (or, if previously commenced, assume control
 of) any proceedings and to obtain any recovery in connection therewith
 which Assignee, its successors and assigns, may deem to be necessary or
 advisable in the premises.

 4.   Further Assurances.  Assignor and Assignee each agree that, at any
      time and from time to time, upon the written request of any other
      party hereto, it will promptly and duly execute and deliver any and
      all such further instruments and documents and take such further
      action as the other may reasonably request in order to obtain the full
      benefits of this Assignment and of the rights and powers herein
      granted.

 5.   No Amendment of Purchase Agreement.  So long as any of the Secured
      Obligations remain outstanding, Assignee agrees that it shall not
      enter into any agreement that would amend, modify, supplement,
      rescind, cancel or terminate the Purchase Agreement or the Consent and
      Guaranty in any respect or in any way limit the rights of Assignor or
      any of the other rights assigned hereunder (except as set forth above
      when there has been an Event of Default), without the prior written
      consent of Assignor.

 6.   Execution of Assignment.  This Assignment is executed by Assignor and
      Assignee concurrently with the execution and delivery of the
      Participation Agreement.

 7.   Confidentiality.  Assignee agrees that it will not disclose to any
      third party the terms of the Purchase Agreement or this Assignment,
      except (a) as required by applicable law or governmental regulation,
      (b) as contemplated in the Participation Agreement (including as set
      forth in Section 7(o) of the Participation Agreement) or (c) with the
      consent of Assignor, Guarantor and AVSA.

 8.   Counterparts.  This Assignment 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.

 9.   GOVERNING LAW.  THIS ASSIGNMENT SHALL IN ALL RESPECTS BE GOVERNED BY,
      AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK,
      INCLUDING ALL MATTERS OF CONSTRUCTION, VALIDITY AND PERFORMANCE.

 10.  Successors and Assigns.  This Assignment shall be binding upon and
      shall inure to the benefit of the parties hereto and their respective
      successors and permitted assigns.

 11.  Notices.  All notices with respect to the matters contained herein
      shall be delivered (notices with respect to AVSA shall be sent to the
      address for AVSA set forth in Clause 2(e) hereof) in the manner
      provided in Section 12(a) of the Participation Agreement.

 12.  No Oral Amendments.  Neither this Assignment nor any of the terms
      hereof may be terminated, amended, supplemented, waived or modified
      orally, but only by an instrument in writing signed by the party
      against whom the enforcement of such termination, amendment,
      supplement, waiver or modification is sought.

 owner of a $281,678,000 (TWO HUNDRED EIGHTY-ONE MILLION, SIX HUNDRED AND
 SEVENTY-EIGHT THOUSAND dollars) Fractional Undivided Interest in the US
 Airways Pass Through Trust, Series 2000-1G (the "Trust") created by State
 Street Bank and Trust Company of Connecticut, National Association, as
 trustee (the "Trustee"), pursuant to a Pass Through Trust Agreement dated
 as of July 30, 1999 (the "Basic Agreement"), between the Trustee, US
 Airways, Inc., a corporation incorporated under Delaware law (the
 "Company") and US Airways Group, Inc., a corporation incorporated under
 Delaware law (the "Parent"), as supplemented by Trust Supplement No. 2000-
 1G thereto dated March 3, 2000, between the Trustee and the Company
 (collectively, the "Agreement"), a summary of certain of the pertinent
 provisions of which is set forth below.  To the extent not otherwise
 defined herein, the capitalized terms used herein have the meanings
 assigned to them in the Agreement.  This Certificate is one of the duly
 authorized Certificates designated as "8.11% US Airways Pass Through
 Certificates, Series 2000-1G" (herein called the "Certificates").  This
 Certificate is issued under and is subject to the terms, provisions and
 conditions of the Agreement.  By virtue of its acceptance hereof, the
 Certificateholder of this Certificate assents to and agrees to be bound by
 the provisions of the Agreement and any related Intercreditor Agreement.
 The property of the Trust includes certain Equipment Notes and all rights
 of the Trust to receive any payments under any Intercreditor Agreement, the
 Policy and any Liquidity Facility (the "Trust Property").  Each issue of
 the Equipment Notes is or will be secured by, among other things, a
 security interest in aircraft leased to or owned by the Company.

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

      Subject to and in accordance with the terms of the Agreement and any
 related Intercreditor Agreement, from funds then available to the Trustee,
 there will be distributed on each February 20 and August 20 (a "Regular
 Distribution Date"), commencing on February 20, 2001, to the Person in
 whose name this Certificate is registered at the close of business on the
 15th day preceding the Regular Distribution Date, an amount in respect of
 the Scheduled Payments on the Equipment Notes due on such Regular
 Distribution Date, the receipt of which has been confirmed by the Trustee,
 equal to the product of the percentage interest in the Trust evidenced by
 this Certificate and an amount equal to the sum of such Scheduled Payments.
 Subject to and in accordance with the terms of the Agreement and any
 related Intercreditor Agreement, in the event that Special Payments on the
 Equipment Notes are received by the Trustee, from funds then available to
 the Trustee, there shall be distributed on the applicable Special
 Distribution Date, to the Person in whose name this Certificate is
 registered at the close of business on the 15th day preceding the Special
 Distribution Date, an amount in respect of such Special Payments on the
 Equipment Notes, the receipt of which has been confirmed by the Trustee,
 equal to the product of the percentage interest in the Trust evidenced by
 this Certificate and an amount equal to the sum of such Special Payments so
 received.  If a Regular Distribution Date or Special Distribution Date is
 not a Business Day, distribution shall be made on the immediately following
 Business Day with the same force and effect as if made on such Regular
 Distribution Date or Special Distribution Date and no interest shall accrue
 during the intervening period.  The Trustee shall mail notice of each
 Special Payment and the Special Distribution Date therefor to the
 Certificateholder of this Certificate.

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

      The Certificates do not represent a direct obligation of, or an
 obligation guaranteed by, or an interest in, the Company or the Trustee or
 any affiliate thereof.  The Certificates are limited in right of payment,
 all as more specifically set forth on the face hereof and in the Agreement.
 All payments or distributions made to Certificateholders under the
 Agreement shall be made only from the Trust Property and only to the extent
 that the Trustee shall have sufficient income or proceeds from the Trust
 Property to make such payments in accordance with the terms of the
 Agreement.  Each Certificateholder of this Certificate, by its acceptance
 hereof, agrees that it will look solely to the income and proceeds from the
 Trust Property to the extent available for distribution to such
 Certificateholder as provided in the Agreement.  This Certificate does not
 purport to summarize the Agreement and reference is made to the Agreement
 for information with respect to the interests, rights, benefits,
 obligations, proceeds, and duties evidenced hereby.  A copy of the
 Agreement may be examined during normal business hours at the principal
 office of the Trustee, and at such other places, if any, designated by the
 Trustee, by any Certificateholder upon request.

      The Agreement permits, with certain exceptions therein provided, the
 amendment thereof and the modification of the rights and obligations of the
 Company and the rights of the Certificateholders under the Agreement at any
 time by the Company and the Trustee with the consent of the
 Certificateholders holding Certificates evidencing Fractional Undivided
 Interests aggregating not less than a majority in interest in the Trust.
 Any such consent by the Certificateholder of this Certificate shall be
 conclusive and binding on such Certificateholder and upon all future
 Certificateholders of this Certificate and of any Certificate issued upon
 the transfer hereof or in exchange hereof or in lieu hereof whether or not
 notation of such consent is made upon this Certificate.  The Agreement also
 permits the amendment thereof, in certain limited circumstances, without
 the consent of the Certificateholders of any of the Certificates.

      As provided in the Agreement and subject to certain limitations set
 forth, the transfer of this Certificate is registrable in the Register upon
 surrender of this Certificate for registration of transfer at the offices
 or agencies maintained by the Trustee in its capacity as Registrar, or by
 any successor Registrar duly endorsed or accompanied by a written
 instrument of transfer in form satisfactory to the Trustee and the
 Registrar, duly executed by the Certificateholder hereof or such
 Certificateholder's attorney duly authorized in writing, and thereupon one
 or more new Certificates of authorized denominations evidencing the same
 aggregate Fractional Undivided Interest in the Trust will be issued to the
 designated transferee or transferees.

      The Certificates are issuable only as registered Certificates without
 coupons in minimum denominations of $1,000 Fractional Undivided Interest
 and integral multiples thereof except that one Certificate may be issued in
 a different denomination.  As provided in the Agreement and subject to
 certain limitations therein set forth, the Certificates are exchangeable
 for new Certificates of authorized denominations evidencing the same
 aggregate Fractional Undivided Interest in the Trust, as requested by the
 Certificateholder surrendering the same.

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

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

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

      The obligations and responsibilities created by the Agreement and the
 Trust created thereby shall terminate upon the distribution to
 Certificateholders of all amounts required to be distributed to them
 pursuant to the Agreement and the disposition of all property held as part
 of the Trust Property.

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

      THE AGREEMENT AND THIS CERTIFICATE SHALL BE GOVERNED BY AND CONSTRUED
 IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK AND THE OBLIGATIONS,
 RIGHTS AND REMEDIES OF THE PARTIES HEREUNDER SHALL BE DETERMINED IN
 ACCORDANCE WITH SUCH LAWS.

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


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

Dear Sirs:

                  US AIRWAYS, INC., a Delaware corporation (the "Company"),
proposes that State Street Bank and Trust Company of Connecticut, National
Association, as pass through trustee (the "Trustee") under the Class G
Trust, issue and sell to the underwriters named in Schedule II hereto its
pass through certificates in the aggregate principal amounts and with the
interest rates and final distribution dates set forth on Schedule I hereto
(the "Certificates") on the terms and conditions stated herein and in
Schedule III.

                  The Certificates will be issued pursuant to the Pass
Through Trust Agreement (the "Basic Agreement") between the Company, US
Airways Group, Inc., a Delaware corporation, and the Trustee, as
supplemented with respect to the Certificates by a separate Pass Through
Trust Supplement to be dated as of the Closing Date (as defined below) (the
"Series Supplement"), between the Company and the Trustee (the Basic
Agreement as supplemented by the Series Supplement being referred to herein
individually as the "Pass Through Agreement"). The Series Supplement is
related to the creation and administration of US Airways Pass Through
Trust, Series 2000-1G (the "Trust").

                  As used herein, unless the context otherwise requires,
the term "Underwriters" shall mean the firms named as Underwriters in
Schedule II, and the term "you" shall mean the Underwriter or Underwriters,
if no underwriting syndicate is purchasing the Certificates or the
representative or representatives of the Underwriters if an underwriting
syndicate is purchasing the Certificates, as indicated in Schedule II.

                  The cash proceeds of the offering of Certificates will be
paid to First Security Bank, National Association, as escrow agent (the
"Escrow Agent"), under an Escrow and Paying Agent Agreement among the
Escrow Agent, the Underwriters, the Trustee and State Street Bank and Trust
Company of Connecticut, National Association, as paying agent (the "Paying
Agent"), for the benefit of the holders of Certificates issued by the Trust
(the "Escrow Agreement"). The Escrow Agent will deposit such cash proceeds
(each, a "Deposit") with ABN AMRO Bank, N.V., acting through its Chicago
branch, (the "Depositary"), in accordance with a Deposit Agreement relating
to the Trust (the "Deposit Agreement"), and will withdraw Deposits upon
request to allow the Trustee to purchase Equipment Notes (as defined in the
Note Purchase Agreement referred to herein) from time to time pursuant to a
Note Purchase Agreement to be dated as of the Closing Date (the "Note
Purchase Agreement") among the Company, State Street Bank and Trust Company
of Connecticut, National Association, as Trustee of the Trust, as
Subordination Agent (as hereinafter defined) and as Paying Agent, and the
Escrow Agent. The Escrow Agent will issue receipts to be attached to each

fractional undivided interest in amounts deposited with such Escrow Agent
and will pay to such holders through the related Paying Agent interest
accrued on the Deposits and received by such Paying Agent pursuant to the
Deposit Agreement at a rate per annum equal to the interest rate applicable
to the Certificates.

                  Certain amounts of interest payable on the Certificates
will be entitled to the benefits of a liquidity facility. Bayerische
Landesbank Girozentrale (the "Liquidity Provider") will enter into a
revolving credit agreement (the "Liquidity Facility") to be dated as of the
Closing Date for the benefit of the holders of the Certificates. The
Liquidity Provider, MBIA Insurance Corporation, as provider of the Policy
referred to below (in such capacity, the "Policy Provider") and the holders
of the Certificates will be entitled to the benefits of an Intercreditor
Agreement to be dated as of the Closing Date (the "Intercreditor
Agreement") among the Trustee, State Street Bank and Trust Company of
Connecticut, National Association, as subordination agent and trustee
thereunder (the "Subordination Agent"), the Policy Provider and the
Liquidity Provider.

                  Payments of interest on the Certificates will be
supported by a financial guaranty insurance policy (the "Policy") issued by
the Policy Provider to the extent the Liquidity Facility and any funds
contained in the cash collateral account funded from such Liquidity
Facility are insufficient or unavailable for that purpose. The Policy will
also support the payment of the final distribution on the Certificates and
will take effect in certain other circumstances described in the
Intercreditor Agreement and the Policy. The Policy will be issued pursuant
to an insurance and indemnity agreement dated as of the Closing Date (the
"Policy Provider Agreement") among the Policy Provider, the Company and the
Subordination Agent. Under the Intercreditor Agreement, the Policy Provider
will be entitled to reimbursement for amounts paid pursuant to claims made
under the Policy.

                  The Company has filed with the Securities and Exchange
Commission (the "Commission") a shelf registration statement on Form S-3
(File No. 333-79825) relating to pass through certificates (such
registration statement, in the form in which it became effective (including
the respective exhibits thereto and the respective documents filed by the
Company with the Commission pursuant to the Securities Exchange Act of

                  The Registration Statement, at the time it became
         effective, did not contain, and the Registration Statement, as
         amended or supplemented, if applicable, will not contain any
         untrue statement of a material fact or omit to state a material
         fact necessary in order to make the statements therein, not
         misleading; the Prospectus, as of the date hereof does not
         contain, and will not contain for so long as you are required to
         deliver a Prospectus in connection with sales or solicitations of
         offers to purchase the Certificates, an untrue statement of a
         material fact or omit to state a material fact necessary in order
         to make the statements therein, in the light of the circumstances
         under which they were made, not misleading; provided, however,
         that the representations and warranties in this subsection (a)
         shall not apply to (i) statements in or omissions from the
         Registration Statement or the Prospectus made in reliance upon and

         Eligibility of Trustee on Form T-1 or (iii) statements in or
         omissions from the Prospectus made with respect to information
         relating to the Policy Provider.

                  The Registration Statement has become effective. No stop
         order suspending the effectiveness of the Registration Statement
         has been issued and no proceedings for that purpose have been
         initiated or threatened by the Commission.

                  (b) The documents incorporated by reference in the

         to make the statements therein, in the light of the circumstances
         under which they were or are made, not misleading; provided,

                  (c) The accountants who certified the financial
         statements pertaining to the Company included or incorporated by
         reference in the Registration Statement or Prospectus are
         independent public accountants as required by the Securities Act.

                  (d) Neither the Company nor any Trust is an "investment
         company", within the meaning of the Investment Company Act of
         1940, as amended (the "Investment Company Act"); and after giving
         effect to the offering and sale of the Certificates and the
         application of the proceeds thereof as described in the
         Prospectus, the Trust will not be, and the escrow arrangements
         relating to the Trust contemplated by the Escrow Agreement will
         not result in the creation of, an "investment company", as defined
         in the Investment Company Act.

                  (e) The Company has complied with all provisions of
         Section 517.075, Florida Statutes (Chapter 92-198, Laws of

         violation of the charter or by-laws of the Company and do not and
         will not conflict with or violate, or result in a breach of any of
         the terms or provisions of, or constitute a default under, or

         any indenture, mortgage or loan agreement, or any other agreement
         or instrument to which the Company is a party or by which it may
         be bound or to which any of its properties may be subject (except
         for such conflicts, breaches, violations, defaults, liens, charges
         or encumbrances that, individually or in the aggregate, would not
         have a material adverse effect on the financial condition or on
         the earnings or business affairs of the Company and its
         subsidiaries considered as a single entity), (ii) any existing
         applicable law, rule or regulation or (iii) any judgment, order or

         of or registration or filing with, or the giving of notice to, any
         government, governmental instrumentality or court, domestic or

         respect to the effectiveness of the Registration Statement under
         the 1933 Act of the qualification of the Pass Through Agreements
         under Trust Indenture Act of 1939, as amended, and the rules and
         regulations of the Commission thereunder (the "1939 Act") and
         other than with respect to the securities or Blue Sky laws of the
         various states) is required to be obtained or made by the Company
         for the valid authorization, execution, delivery and performance
         by the Company of this Agreement or any of the Operative Documents
         to which the Company is or will be a party or the consummation of
         the transactions contemplated by this Agreement or any such
         Operative Documents, except such as may be required under (i) the
         securities or Blue Sky laws of the various states or (ii) the
         Transportation Code and the Uniform Commercial Code as in effect
         in Utah and Virginia, which filings or recordings referred to in
         this clause (ii), with respect to any particular set of Financing
         Agreements, shall have been made or duly presented for filing or
         recordation in all material respects or shall be in the process of
         being duly filed or filed for recordation in all material
         respects, on or prior to the applicable Delivery Date (as defined
         in the Participation Agreements) for the Aircraft related to such
         Financing Agreements.

                  (h) This Agreement has been duly authorized by all
         necessary corporate action and duly executed and delivered by the
         Company. The Operative Documents to which the Company will be a
         party will be duly executed and delivered by the Company on or
         prior to the Closing Date or the applicable Delivery Date (as
         defined in the Participation Agreements), as the case may be.

                  (i) The Operative Documents to which the Company is or
         will be a party have been duly authorized by all necessary
         corporate action, will each be substantially in the form
         heretofore supplied to you and will constitute, when duly executed
         and delivered by the Company (assuming that such Operative
         Documents constitute valid and binding obligations of each other
         party thereto), valid and binding obligations of the Company,
         enforceable against the Company in accordance with their terms,
         except to the extent that enforceability thereof may be limited by
         (i) bankruptcy, insolvency, reorganization, moratorium or other
         similar laws now or hereafter in effect relating to creditors'
         rights generally and (ii) general principles of equity (regardless
         of whether enforceability is considered in a proceeding at law or
         in equity). The Basic Agreement as executed is substantially in
         the form filed as an exhibit to the Registration Statement and has
         been duly qualified under the 1939 Act. The Certificates and the
         Operative Documents to which the Company is, or is to be, a party
         will conform in all material respects to the descriptions thereof
         in the Prospectus.

                  (j) When executed, issued, authenticated and delivered
         pursuant to the provisions of the Pass Through Agreement and sold
         and paid for as provided in this Agreement, the Certificates will
         constitute valid and legally binding obligations of the Trustee
         enforceable in accordance with their terms, except to the extent
         that enforceability thereof may be limited by (i) bankruptcy,
         insolvency, reorganization, moratorium or other similar laws now
         or hereafter in effect relating to creditors' rights generally and
         (ii) general principles of equity (regardless of whether
         enforceability is considered in a proceeding at law or in equity);
         and the Certificates will be entitled to the benefits provided by
         such Pass Through Agreement. When executed, authenticated, issued
         and delivered in the manner provided for in the Escrow Agreement,
         the Escrow Receipts will be legally and validly issued and will be
         entitled to the benefits of the Escrow Agreement.

                  (k) The Equipment Notes to be issued under each
         applicable Indenture, when duly executed and delivered by the
         related Owner Trustee or the Company, as the case may be, and duly
         authenticated by the Indenture Trustee in accordance with the
         terms of such Indenture, will be duly issued under such Indenture
         and will constitute the valid and binding obligations of such
         Owner Trustee or the Company, as the case may be, enforceable in
         accordance with their terms, except that enforceability thereof
         may be limited by (i) bankruptcy, insolvency, reorganization,
         moratorium or other similar laws now or hereafter in effect
         relating to creditors' rights generally and (ii) general
         principles of equity (regardless of whether enforceability is
         considered in a proceeding at law or in equity); and the Holders
         thereof will be entitled to the benefits of such Indenture.

                  (l) No Appraiser nor the Policy Provider is an affiliate
         of the Company or has a substantial interest, direct or indirect,
         in the Company. None of the officers and directors of any of the
         Appraisers or of the Policy Provider is connected with the Company
         or any of its affiliates as an officer, employee, promoter,
         underwriter, trustee, partner, director or person performing
         similar functions.

                  (m) Each preliminary prospectus filed as part of the
         registration statement as originally filed or as part of any
         amendment thereto, or filed pursuant to Rule 424 under the
         Securities Act, when so filed complied as to form in all material
         respects with the Securities Act.

                  The parties agree that any certificate signed by a duly
authorized officer of the Company and delivered to an Underwriter, or to
counsel for the Underwriters, on the Closing Date and in connection with
this Agreement or the offering of the Certificates, shall be deemed a
representation and warranty by (and only by) the Company to the
Underwriters as to the matters covered thereby.

                  2. Purchase and Delivery. (a) On the basis of the
representations, warranties and agreements herein contained, but subject to
the terms and the conditions herein set forth and in Schedule III, the
Company agrees to cause the Trustee to sell to each Underwriter, and each
Underwriter agrees, severally and not jointly, to purchase from the
Trustee, at the purchase price specified in Schedule I, the respective
amounts of each Class of Certificates set forth opposite the name of such
Underwriter in Schedule II. Concurrently with the issuance of the
Certificates, the Escrow Agent shall issue and deliver to the Trustee the
Escrow Receipts in accordance with the terms of the Escrow Agreement, which
Escrow Receipts shall be attached to the related Certificates.

                  (b) The Company is advised by you that the Underwriters
propose to make a public offering of the Certificates as soon after this
Agreement has been entered into as in your judgment is advisable as set
forth in the Prospectus.

                  (c) As compensation to the Underwriters for their
respective commitments and obligations hereunder in respect of the
Certificates, including their respective undertakings to distribute the
Certificates, the Company will pay to you for the accounts of the
Underwriters the amount set forth in Schedule III hereto, which amount
shall be allocated among the Underwriters in the manner determined by you.
Such payment will be made on the Closing Date simultaneously with the
issuance and sale of the Certificates (with the related Escrow Receipts
attached) to the Underwriters. Payment of such compensation shall be made
by wire transfer of immediately available funds.

                  (d) Delivery of and payment of the purchase price for the
Certificates to be purchased by the Underwriters (with attached Escrow
Receipts) shall be made at the offices of Skadden, Arps, Slate, Meagher &
Flom, LLP, 4 Times Square, New York, NY 10036 (or at such other place as
shall be agreed upon by you and the Company) at 10:00 A.M., New York City
time, on the fifth business day following the date hereof or such other
date, time and place as may be agreed upon by the Company and you (such
date and time of delivery and payment for the Certificates (with attached
Escrow Receipts) being herein called the "Closing Date"). Delivery of the
Certificates (with attached Escrow Receipts) issued by the Trust shall be
made to your account at The Depository Trust Company ("DTC") for the
respective accounts of the several Underwriters against payment by the
Underwriters of the purchase price thereof by wire transfer of immediately
available funds to the accounts and in the manner specified in the Escrow
Agreement. The Certificates (with attached Escrow Receipts) shall be in the
form of one or more fully registered global certificates, and shall be
deposited with the Trustee as custodian for DTC and registered in the name
of Cede & Co.

                  (e) The Company agrees to have the Certificates (with
attached Escrow Receipts) available for inspection and checking by you in
New York, New York not later than 1:00 P.M. on the business day prior to
the Closing Date.

                  3. Conditions to Closing. The several obligations of the
Underwriters to purchase and pay for the Certificates pursuant to this
Agreement are subject to the accuracy of and compliance with the
representations and warranties of the Company contained herein as of the
date hereof and the Closing Date, to the accuracy of the statements of the
officers of the Company made in any certificate furnished pursuant to the
provisions hereof, to the performance by the Company of its covenants and
other obligations hereunder and to the following further conditions:

                  (a) Subsequent to the execution and delivery of this
         Agreement and prior to the Closing Date, there shall not have
         occurred any downgrading in the rating accorded any of the
         securities of the Company by Moody's Investors Service, Inc. or
         Standard & Poor's Ratings Service, nor shall any notice have been
         given of (i) any intended or potential downgrading or (ii) any
         review or possible change in such rating.

                  (b) Subsequent to the execution and delivery of this
         Agreement and prior to the Closing Date, there shall not have
         occurred any material adverse change, or any development
         reasonably likely to result in a material adverse change, in the
         financial condition or in the earnings or business affairs of the
         Company from that set forth or contemplated in the Prospectus,
         that, in your judgment, makes it impracticable to market the
         Certificates on the terms and in the manner contemplated in the
         Prospectus.

                  (c) You shall have received on the Closing Date a
         certificate, dated the Closing Date and signed by a Vice

         effect (i) that no event set forth in clause (a) above has
         occurred, (ii) that the representations and warranties of the
         Company contained herein are true and correct as of the Closing
         Date (except to the extent that a representation or warranty
         expressly relates to an earlier or later date, in which case it
         will be true and correct as of such date), (iii) that there shall
         not have occurred any material adverse change, or any development
         reasonably likely to result in a material adverse change, in the
         financial condition or in the earnings or business affairs of the
         Company from that set forth or contemplated in the Prospectus, and
         (iv) that the Company shall have performed in all material
         respects all of its obligations to be performed hereunder on or
         prior to the Closing Date. The officer signing and delivering such
         certificate may rely on the best of his or her knowledge.

                  (d) You shall have received on the Closing Date an
         opinion, dated the Closing Date, from the General Counsel, Deputy
         General Counsel or Associate General Counsel of the Company, in
         form satisfactory to you and your counsel, to the effect that:

                  and each of the Operative Documents to which it is a
                  party and to perform its obligations hereunder and
                  thereunder (except where the failure to have such power
                  or authority would not have a material adverse effect on
                  the Company); and the Company is duly qualified to
                  transact business as a foreign corporation in good
                  standing in each jurisdiction in which its ownership of
                  property or the conduct of its business requires such
                  qualification (except where the failure to so qualify
                  would not have a material adverse effect upon the
                  Company);

                           (ii) The Company is an "air carrier" and a

                  Prospectus with respect to statutes, contracts,

                  governmental proceedings are accurate and fairly
                  summarize the information required to be shown; and there
                  are, to the best of such counsel's knowledge, no
                  statutes, administrative orders or regulations or pending
                  or threatened legal or governmental proceedings required
                  to be described in the Registration Statement or the

                  authorized to operate are correct in all material
                  respects. Except as disclosed in the Prospectus, no
                  action or proceeding has been instituted or to such
                  counsel's knowledge, has been threatened by the United

                  Administration or the aeronautical authorities of any
                  other country that would impair the Company's ability to
                  operate such routes;

                           (iv)     This Agreement has been duly authorized,

                  such counsel of any government, governmental
                  instrumentality or court, domestic or foreign, having
                  jurisdiction over the Company or any of its properties;

                           (vii) No default exists in the performance or
                  observance of any material obligation, agreement,

                  such counsel, threatened against or affecting the Company
                  that might reasonably be expected to result in any
                  material adverse change in the financial condition or in
                  the earnings or business affairs of the Company, or that
                  could adversely affect the consummation of the
                  transactions contemplated by this Agreement or any of the
                  other Operative Documents to which the Company is a
                  party; and

                           (ix) Such counsel has participated in the
                  preparation of the Registration Statement, the Prospectus
                  and the documents incorporated by reference in the
                  Prospectus and such counsel has no reason to believe (A)
                  that the Registration Statement or any amendment thereto
                  (except for the financial statements and other financial
                  or statistical data included or incorporated by reference
                  therein or omitted therefrom, and except for the
                  Statement of Eligibility on Form T-1 of the Trustee, as
                  to which such counsel need express no opinion), at the
                  time the Registration Statement became effective,
                  contained and, as of the date such opinion is delivered,
                  contains any untrue statement of a material fact or
                  omitted to state a material fact required to be stated
                  therein or necessary to make the statements therein not
                  misleading, or (B) that the Prospectus or any amendment
                  or supplement thereto (except for (1) the financial
                  statements and other financial or statistical data
                  included or incorporated by reference therein or omitted
                  therefrom and (2) statements in or omissions from the
                  Prospectus made with respect to information relating to
                  the Policy Provider, as to both of which such counsel
                  need express no opinion), at the time the Prospectus was
                  issued, at the time any amended or supplemented
                  Prospectus was issued or as of the Closing Date,
                  contained or contains any untrue statement of a material
                  fact or omitted or omits to state a material fact
                  necessary in order to make the statements therein, in the
                  light of the circumstances under which they were made,
                  not misleading.

with each Underwriter as follows:

                  (a) The Company has prepared a preliminary prospectus,
         and immediately following the execution of this Agreement, the
         Company will prepare a Prospectus Supplement in connection with
         the offering of the Certificates. The Company will promptly
         transmit copies of the Prospectus Supplement to the Commission for
         filing pursuant to Rule 424 under the Securities Act.

                  (b) The Company will notify you promptly (i) of the
         effectiveness of any amendment to the Registration Statement, (ii)
         of the transmittal to the Commission for filing of any supplement
         to the Prospectus or any document to be filed pursuant to the
         Exchange Act which will be incorporated by reference in the
         Prospectus, (iii) of the receipt of any comments from the
         Commission with respect to the Registration Statement, the
         Prospectus or the Prospectus Supplement relating in any way to the
         offer and sale of the Certificates, (iv) of any request by the
         Commission for any amendment to the Registration Statement or any
         amendment or supplement to the Prospectus or for additional
         information and (v) of the issuance by the Commission of any stop
         order suspending the effectiveness of the Registration Statement
         or the initiation of any proceedings for that purpose.

                  (c) The Company will give you notice of its intention to
         file or prepare any amendment to the Registration Statement or any
         amendment or supplement to the Prospectus, whether by the filing
         of documents pursuant to the Exchange Act, the Securities Act or
         otherwise, and will furnish you with copies of any such amendment
         or supplement or other documents proposed to be filed or prepared
         a reasonable time in advance of such proposed filing or
         preparation, as the case may be.

                  (d) The Company will deliver to you as many signed and
         conformed copies of the Registration Statement (as originally
         filed) and of each amendment thereto (including exhibits filed
         therewith or incorporated by reference therein and documents
         incorporated by reference in the Prospectus) as you may reasonably
         request. The Company will furnish to you, without charge, as many
         copies of the Prospectus and any supplements and amendments
         thereto as you may reasonably request so long as you are required
         to deliver a Prospectus in connection with sales or solicitations
         of offers to purchase the Certificates.

                  (e) If, during the period after the first date of the
         public offering of the Certificates as in the written opinion of
         counsel for the Underwriters (which counsel shall be reasonably
         acceptable to the Company, provided that Milbank, Tweed, Hadley &
         McCloy LLP shall be acceptable to the Company) the Prospectus is
         required by the Securities Act to be delivered in connection with
         sales of the Certificates by an Underwriter or dealer any event
         shall occur or condition exist as a result of which it is
         necessary to amend or supplement the Prospectus in order that the
         Prospectus will not include an untrue statement of a material fact
         or omit to state any material fact necessary in order to make the
         statements therein in the light of the circumstances existing at
         the time it is delivered to a purchaser, not misleading or if it
         shall be necessary, at any such time to amend or supplement the
         Registration Statement or the Prospectus in order to comply with
         the requirements of the Securities Act or the rules and
         regulations of the Commission thereunder, the Company will
         promptly prepare and file with the Commission such amendment or
         supplement, whether by filing documents pursuant to the Exchange
         Act, the Securities Act or otherwise, as may be necessary to
         correct such untrue statement or omission or to make the
         Registration Statement and Prospectus comply with such
         requirements.

                  (f) The Company will endeavor to qualify the Certificates
         for offer and sale under the securities or Blue Sky laws of such
         jurisdictions as you shall reasonably request and to maintain such
         qualification for as long as you shall reasonably request
         (provided, however, that the Company shall not be obligated to
         file any general consent to service of process or to qualify as a
         foreign corporation or to subject itself to taxation as doing
         business in any jurisdiction in which it is not otherwise required
         to be so qualified) and to pay all expenses (including reasonable
         fees and disbursements of counsel) in connection with such
         qualification and in connection with the determination of the
         eligibility of the Certificates for investment under the laws of
         such jurisdictions as you may designate, as well as all reasonable
         expenses payable in connection with the review (if any) of the
         offering of the Certificates by the National Association of
         Securities Dealers, Inc. (including any filing fees and reasonable
         fees and expenses of counsel for the Underwriters in connection
         therewith).

                  (g) Whether or not any sale of such Certificates is
         consummated, the Company will pay or cause to be paid all expenses
         incident to the performance of its obligations under this
         Agreement, including: (i) the preparation and filing of any and
         all amendments to the Registration Statement and any and all
         amendments to the Prospectus; (ii) the filing of this Agreement;
         (iii) the preparation, issuance and delivery of the Certificates;

         accountants and counsel, of the Trustee, the Subordination Agent,
         the Liquidity Provider, the Depositary, the Escrow Agent, the
         related Owner Trustees and the Indenture Trustee and their
         respective counsel, and of any registrar, paying agent and
         authenticating agent; (v) the qualification of the Certificates
         under securities laws in accordance with the provisions of Section
         4(f), including filing fees and the reasonable fees and
         disbursements of counsel to the Underwriters in connection
         therewith and in connection with the preparation of any Blue Sky
         Survey and any Legal Investment Survey; (vi) one half of all
         reasonable fees and expenses of counsel to the Underwriters; (vii)
         the printing and delivery to the Underwriters in quantities as
         hereinabove stated of copies of the Registration Statement and any
         amendments thereto, and of the Prospectus and any amendments or
         supplements thereto, and the delivery by the Underwriters of the
         Prospectus and any amendments or supplements thereto in connection
         with solicitations or confirmations of sales of the Certificates;
         (viii) the preparation and delivery to the Underwriters of copies
         of the Pass Through Agreement and the other Operative Documents,
         including all expenses incident to the performance of the
         Company's obligations under the Pass Through Agreement,
         Participation Agreements, Indentures, Leases and each of the other
         agreements and instruments referred to in the Indentures and
         Participation Agreements; (ix) any fees charged by rating agencies
         for the rating of the Certificates; and (x) all other costs and
         expenses incident to the performance of the obligations of the
         Company hereunder for which provision is not otherwise made in
         this Section.

                  (h) The Company will not, during the period beginning on
         the date of this Agreement and continuing to the Closing Date,
         offer or sell, or enter into any agreement to sell, any equipment
         notes, pass through certificates, equipment trust certificates or
         equipment purchase certificates secured by aircraft owned or
         leased by the Company (or rights relating thereto), other than the
         Equipment Notes relating thereto, without the prior written
         consent of the Underwriters.

                  (i) The Company, during the period when the Prospectus is
         required to be delivered under the Securities Act, will file
         promptly all documents required to be filed with the Commission
         pursuant to Section 13, 14 or 15(d) of the Exchange Act.

                  (j) The Company will make generally available to its
         securities holders and you as soon as practicable (but in any
         event not later than 45 days) after the close of the period
         covered thereby, an earnings statement (which shall satisfy the
         provisions of Section 11(a) under the Securities Act) covering
         each twelve-month period beginning, in each case, not later than
         the first day of the Company's first full fiscal quarter after the
         date of this Agreement.

                  5. Indemnification and Contribution. (a) The Company
agrees to indemnify and hold harmless each Underwriter, and each person, if
any, who controls such Underwriter within the meaning of either Section 15
of the Securities Act or Section 20 of the Exchange Act, from and against
any and all losses, claims, damages and liabilities caused by any untrue
statement or alleged untrue statement of a material fact contained in the
Registration Statement or any amendment thereof, any preliminary prospectus
or the Prospectus (as amended or supplemented if the Company shall have
furnished any amendments or supplements thereto), or caused by any omission
or alleged omission to state therein a material fact required to be stated
therein or necessary to make the statements therein in the light of the
circumstances under which they were made not misleading, except insofar as
such losses, claims, damages or liabilities are caused by any such untrue
statement or omission or alleged untrue statement or omission based upon
information relating to: (i) any Underwriter furnished to the Company in
writing by such Underwriter through SSB expressly for use therein; and (ii)
the Policy Provider; provided, however, that the foregoing indemnity
agreement, with respect to any Preliminary Prospectus shall not inure to
the benefit of any Underwriter from whom the person asserting any such
losses, claims, damages or liabilities purchased Certificates, or any
person controlling such Underwriter, if a copy of the Prospectus (as then
amended or supplemented if the Company shall have furnished any amendments
or supplements thereto) was not sent or given by or on behalf of such
Underwriter to such person, if required by law so to have been delivered,
at or prior to the written confirmation of the sale of the Certificates to
such person, and if the Prospectus (as so amended or supplemented) would
have cured the defects giving rise to such losses, claims, damages or
liabilities.

                  (b) Each Underwriter agrees, severally and not jointly,
to indemnify and hold harmless the Company, its directors, its officers who
sign the Registration Statement and each person, if any, who controls the
Company within the meaning of either Section 15 of the Securities Act or
Section 20 of the Exchange Act to the same extent as the foregoing
indemnity from the Company to such Underwriter, but only with reference to
information relating to such Underwriter furnished to the Company in
writing by such Underwriter through SSB expressly for use in the
Registration Statement, any preliminary prospectus, the Prospectus or any
amendments or supplements thereto.

                  (c) In case any proceeding (including any governmental
investigation) shall be instituted involving any person in respect of which
indemnity may be sought pursuant to either paragraph (a) or (b) above, such
person (the "indemnified party") shall promptly notify the person against
whom such indemnity may be sought (the "indemnifying party") in writing and
the indemnifying party, upon request of the indemnified party, shall retain
counsel reasonably satisfactory to the indemnified party to represent the
indemnified party and any others the indemnifying party may designate in
such proceeding and shall pay the reasonable fees and disbursements of such
counsel related to such proceeding. In any such proceeding, any indemnified
party shall have the right to retain its own counsel, but the reasonable
fees and expenses of such counsel shall be at the expense of such
indemnified party unless (i) the indemnifying party and the indemnified
party shall have agreed to the retention of such counsel or (ii) the named
parties to any such proceeding (including any impleaded parties) include
both the indemnifying party and the indemnified party and representation of
both parties by the same counsel would be inappropriate due to actual or
potential differing interests between them. It is understood that the
indemnifying party shall not, in connection with any proceeding or related
proceedings in the same jurisdiction, be liable for the reasonable fees and
expenses of more than one firm (in addition to any local counsel) for all
such indemnified parties and that all such fees and expenses shall be
reimbursed as they are incurred. Such firm shall be designated in writing
by SSB in the case of parties indemnified pursuant to paragraph (a) above
and by the Company in the case of parties indemnified pursuant to paragraph
(b) above. The indemnifying party shall not be liable for any settlement of
any proceeding effected without its written consent, but if settled with
such consent or if there be a final judgment for the plaintiff, the
indemnifying party agrees to indemnify the indemnified party from and
against any loss or liability by reason of such settlement or judgment. No
indemnifying party shall, without the prior written consent of the
indemnified party, effect any settlement of any pending or threatened
proceeding in respect of which any indemnified party is or could have been
a party and indemnity could have been sought hereunder by such indemnified
party, unless such settlement includes an unconditional release of such
indemnified party from all liability on claims that are the subject matter
of such proceeding and does not include a statement as to or an admission
of fault, culpability or failure to act by or on behalf of any indemnified
party.

                  (d) To the extent the indemnification provided for in
paragraph (a) or (b) of this Section 5 is unavailable to an indemnified
party or insufficient in respect of any losses, claims, damages or
liabilities, then each indemnifying party under such paragraph, in lieu of
indemnifying such indemnified party thereunder, shall contribute to the
amount paid or payable by such indemnified party as a result of such
losses, claims, damages or liabilities (i) in such proportion as is
appropriate to reflect the relative benefits received by the Company, on
the one hand, and the Underwriters, on the other hand, from the offering of
the Certificates or (ii) if the allocation provided by clause (i) above is
not permitted by applicable law, in such proportion as is appropriate to
reflect not only the relative benefits referred to in clause (i) above but
also the relative fault of the Company on the one hand and the Underwriters
on the other hand in connection with the statements or omissions that
resulted in such losses, claims, damages or liabilities, as well as any
other relevant equitable considerations. The relative benefits received by
the Company on the one hand and the Underwriters on the other hand in
connection with the offering of the Certificates shall be deemed to be in
the same respective proportions as the net proceeds from the offering of
such Certificates (before deducting expenses) received by the Trusts and
the total underwriting discounts and commissions received by the
Underwriters, in each case as set forth in (or in the notes to) the table
on the cover of the Prospectus, bear to the aggregate offering price of the
Certificates. The relative fault of the Company on the one hand and of the
Underwriters on the other hand shall be determined by reference to, among
other things, whether the untrue or alleged untrue statement of a material
fact or the omission or alleged omission to state a material fact relates
to information supplied by the Company or by the Underwriters and the
parties' relative intent, knowledge, access to information and opportunity
to correct or prevent such statement or omission. The Underwriters'
respective obligations to contribute pursuant to this Section 5 are several
in proportion to the respective principal amount of Certificates they have
purchased hereunder, and not joint.

                  (e) The Company and the Underwriters agree that it would
not be just or equitable if contribution pursuant to this Section 5 were
determined by pro rata allocation (even if the Underwriters were treated as
one entity for such purpose) or by any other method of allocation that does
not take account of the equitable considerations referred to in paragraph
(d) above. The amount paid or payable by an indemnified party as a result
of the losses, claims, damages and liabilities referred to in paragraph (d)
above shall be deemed to include, subject to the limitations set forth
above, any legal or other expenses reasonably incurred by such indemnified
party in connection with investigating or defending any such action or
claim. Notwithstanding the provisions of this Section 5, no Underwriter
shall be required to contribute any amount in excess of the amount by which
the total price at which the Certificates underwritten by it and
distributed to the public were offered to the public exceeds the amount of
any damages that such Underwriter has otherwise been required to pay by
reason of such untrue or alleged untrue statement or omission or alleged
omission. No person guilty of fraudulent misrepresentation (within the
meaning of Section 11(f) of the Securities Act) shall be entitled to
contribution from any person who was not guilty of such fraudulent
misrepresentation. The indemnity and contribution provisions contained in
this Section 5 and the representations and warranties of the Company
contained in this Agreement shall remain operative and in full force and
effect regardless of (i) any termination of this Agreement, (ii) any
investigation made by or on behalf of any Underwriter or any person
controlling any Underwriter or by or on behalf of the Company, its officers
or directors or any person controlling the Company and (iii) acceptance of
and payment for any of the Certificates. The remedies provided for in this
Section 5 are not exclusive and shall not limit any rights or remedies
which may otherwise be available to any indemnified party at law or in
equity.

                  (f) The indemnity and contribution provisions contained
in this Section and the representations, warranties and other statements of
the Company contained in this Agreement or contained in certificates of
officers of the Company submitted pursuant hereto, shall remain operative
and in full force and effect regardless of (i) any termination of this
Agreement, (ii) any investigation made by or on behalf of any Underwriter
or any person controlling any Underwriter or the Company, its officers or
directors or any person controlling the Company and (iii) acceptance of and
payment for any of the Certificates.

                  6. Termination. This Agreement shall be subject to
termination in your absolute discretion, by oral notice confirmed in
writing, given by you to the Company, which notice cites one of the
specific events set forth below that has occurred, if (a) after the
execution and delivery of this Agreement and prior to the Closing Date (i)
trading generally shall have been suspended on or by, as the case may be,
any of the New York Stock Exchange, the American Stock Exchange, the
National Association of Securities Dealers, Inc., or the Chicago Board of
Options Exchange, (ii) trading of any securities of the Company shall have
been suspended on any exchange or in any over-the-counter market, (iii) a
general moratorium on commercial banking activities in New York shall have
been declared by either federal or New York State authorities or (iv) there
shall have occurred any outbreak or escalation of hostilities or any change
in financial markets or any calamity or crisis that, in your judgment, is
material and adverse and (b) in the case of any of the events specified in
clauses (a)(i) through (iv), such event singly or together with any other
such event makes it, in your judgment, impracticable to market the
Certificates on the terms and in the manner contemplated in the Prospectus.

                  7. Default of Underwriters. If, on the Closing Date, any
one or more of the Underwriters shall fail or refuse to purchase
Certificates that it has or they have agreed to purchase hereunder on such
date, and the aggregate principal amount of Certificates which such
defaulting Underwriter or Underwriters agreed but failed or refused to
purchase is not more than one-tenth of the aggregate principal amount of
Certificates, the other Underwriters shall be obligated severally in the
proportions that the principal amount of Certificates set forth opposite
their respective names in Schedule II bears to the aggregate principal
amount of Certificates set forth opposite the names of all such
non-defaulting Underwriters, or in such other proportions as you may
specify, to purchase the Certificates which such defaulting Underwriter or
Underwriters agreed but failed or refused to purchase on such date;
provided that in no event shall the principal amount of Certificates that
any Underwriter has agreed to purchase pursuant to this Agreement be
increased pursuant to this Section 7 by an amount in excess of one-ninth of
such principal amount of Certificates without the written consent of such
Underwriter. If on the Closing Date any Underwriter or Underwriters shall
fail or refuse to purchase Certificates which it or they have agreed to
purchase hereunder on such date and the aggregate principal amount of
Certificates with respect to which such default occurs is more than
one-tenth of the aggregate principal amount of Certificates to be purchased
on such date and arrangements satisfactory to you and the Company for the
purchase of such Certificates are not made within 36 hours after such
default, this Agreement shall terminate without liability on the part of
any non-defaulting Underwriter or of the Company. In any such case either
you or the Company shall have the right to postpone the Closing Date, but
in no event for longer than seven days, in order that the required changes,
if any, in the Registration Statement and the Prospectus or in any other
documents or arrangements may be effected. Any action taken under this
Section shall not relieve any defaulting Underwriter from liability in
respect of any default of such Underwriter under this Agreement.

                  If this Agreement shall be terminated by the
Underwriters, or any of them, because of any failure or refusal on the part
of the Company to comply with the terms or to fulfill any of the conditions
of this Agreement, or if for any reason the Company shall be unable to
perform its obligations under this Agreement, the Company will reimburse
the Underwriters or such Underwriters as have so terminated this Agreement
with respect to themselves, severally, for all out-of-pocket expenses
(including the fees and disbursements of their counsel) reasonably incurred
by such Underwriters in connection with this Agreement or the offering
contemplated hereunder.

                  8.    Notices. All notices and other communications under
this Agreement shall be in writing, unless otherwise stated herein, and
shall be deemed to have been duly given if delivered, mailed or transmitted
by any standard form of telecommunication. Notices to you shall be directed
to you, c/o Salomon Smith Barney Inc., 390 Greenwich Street, 4th Floor, New
York, New York 10013, Attention: John F. Grier; and notices to the Company
shall be directed to it at US Airways, Inc., Crystal Park Four, 2345
Crystal Drive, Arlington, VA 22227, Attention: Treasurer.

                  9.   Counterparts. This Agreement may be signed in any
number of counterparts, each of which shall be an original, with the same
effect as if the signatures thereto and hereto were upon the same
instrument.

                  10.    APPLICABLE LAW. THIS AGREEMENT SHALL BE GOVERNED BY
AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK WITHOUT
REGARD TO PRINCIPLES OF CONFLICTS OF LAWS.

                  11.    Headings. The headings of the sections of this
Agreement have been inserted for convenience of reference only and shall
not be deemed a part of this Agreement.

                  Please confirm your agreement to the foregoing by signing

hereof, whereupon this Agreement shall constitute a binding agreement
between us.

                                       Very truly yours,

                                       US AIRWAYS, INC.
