and interest in and to the Purchase Agreement) together with all rights, powers,
privileges, options and other benefits of the Owner thereunder (subject to such
reservation) with respect to the Airframe or the Engines, including, without

Owner's reasonable business judgment) and to retain any recovery or benefit
resulting from the enforcement of any warranty or indemnity under the Purchase
Agreement; and PROVIDED FURTHER THAT, notwithstanding the occurrence or
continuation of an Event of Default, the Mortgagee shall not enter into any
amendment of the Purchase Agreement which would increase the obligations of the
Owner thereunder.

            TO HAVE AND TO HOLD all and singular the aforesaid property unto the
Mortgagee, and its successors and assigns, in trust for the equal and
proportionate benefit and security of the Note Holders and the Indenture
Indemnitees, except as provided in Section 2.13 and Article III hereof, without
any preference, distinction or priority of any one Equipment Note over any other

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 shall remain liable under the Indenture
Agreements 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 Mortgagee, the Note Holders and the Indenture
Indemnitees shall have no obligation or liability under the Indenture Agreements
by reason of or arising out of the assignment hereunder, nor shall the
Mortgagee, the Note Holders or the Indenture Indemnitees be required or
obligated in any manner to perform or fulfill any obligations of the Owner under
or pursuant to the Indenture Agreements, 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.

            The Owner does hereby constitute the Mortgagee the true and lawful
attorney of the 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 the 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 Collateral, 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
Mortgagee may deem to be necessary or advisable in the premises; PROVIDED that

<PAGE>

the Mortgagee shall not exercise any such rights except upon the occurrence and
during the continuance of an Event of Default hereunder.

            The Owner agrees that at any time and from time to time, upon the
written request of the Mortgagee, the Owner will promptly and duly execute and
deliver or cause to be duly executed and delivered any and all such further
instruments and documents (including without limitation UCC continuation
statements) as the Mortgagee may reasonably deem necessary to perfect, preserve
or protect the mortgage, security interests and assignments created or intended
to be created hereby or to obtain for the Mortgagee the full benefits of the
assignment hereunder and of the rights and powers herein granted.

            IT IS HEREBY COVENANTED AND AGREED by and between the parties hereto

interest shall accrue on the amount of such payment during such extension.

            For purposes hereof, the term "Trust Indenture" means the Trust

Owner and Wilmington Trust Company (the "Mortgagee"), as the same may be amended

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 Mortgagee or at the office of any successor in the manner provided
in Section 2.07 of the Trust Indenture.

            The Original Amount and interest and other amounts due hereunder
shall be payable in Dollars in immediately available funds at the Corporate
Trust Office of the Mortgagee, 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 Mortgagee for cancellation.

            The holder hereof, by its acceptance of this Equipment Note, agrees
that, except as provided in the Trust Indenture, each payment of the Original

well as any interest on any overdue Original 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 Original Amount of this Equipment Note then due, THIRD, to the payment of

<PAGE>

            SECTION 2.02. ISSUANCE AND TERMS OF EQUIPMENT NOTES

            The Equipment Notes shall be dated the date of issuance thereof,
shall be issued in up to six separate series consisting of Series A-1, Series
A-2, Series B, Series C and Series D and in the maturities and principal amounts
and shall bear interest as specified in Schedule I hereto (or, in the case of
the Series D if issued after the Closing Date, as specified in an amendment to
this Trust Indenture). On the date thereof, each Series specified in Schedule I
shall be issued to the Subordination Agent on behalf of the Applicable Pass
Through Trustee under the Applicable Pass Through Trust Agreement. Owner shall
have the option to issue the Series D Equipment Notes at or after the Closing.
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 Original Amount thereof from time to time outstanding, payable in arrears
on [____ __, 20__], and on each [______] and [______] thereafter until maturity.
The Original Amount of each Equipment Note (i) in the case of Equipment Notes
other than Series A-2, shall be payable on the dates and in the installments
equal to the corresponding percentage of the Original Amount as set forth in
Schedule I hereto which shall be attached as Schedule I to such Equipment Notes
(or, in the case of the Series D Equipment Notes if issued after the Closing
Date, as set forth in an amendment to this Trust Indenture, which payment
schedule shall be attached as Schedule I to the Series D Equipment Notes) and
(ii) in the case of the Series A-2 Equipment Notes, shall be paid in full on
[_________]. Notwithstanding the foregoing, the final payment made under each
Equipment Note shall be in an amount sufficient to discharge in full the unpaid
Original 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
Payment Due Rate (calculated on the basis of a year of 360 days comprised of
twelve 30-day months) on any part of the Original 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 and if such
payment is made on such next succeeding Business Day, no interest shall accrue
on the amount of such payment during such extension.

            The Owner agrees to pay to the Mortgagee for distribution in
accordance with Section 3.04 hereof: (i) to the extent not payable (whether or
not in fact paid) under Section 6(a) of the Note Purchase Agreement, an amount
equal to the fees payable to 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 A-1 Equipment Notes, Series
A-2 Equipment Notes, Series B Equipment Notes and Series C Equipment Notes and

<PAGE>

the denominator of which shall be the then outstanding aggregate principal
amount of all "Series A-1 Equipment Notes," "Series A-2 Equipment Notes,"
"Series B Equipment Notes" and "Series C Equipment Notes" (each as defined in
the Note Purchase Agreement); (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 A-1 Equipment Notes, Series A-2 Equipment Notes,
Series B Equipment Notes or Series C Equipment Notes, (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 over (2) the sum of Investment Earnings from any Final Advance plus any
amount of interest at the Payment Due Rate actually payable (whether or not in
fact paid) by Owner on 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 multiplied by (y) a fraction the numerator of
which shall be the then aggregate overdue amounts of interest on the Series A-1
Equipment Notes, Series A-2 Equipment Notes, Series B 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 A-1
Equipment Notes," "Series A-2 Equipment Notes," "Series B Equipment Notes" and
"Series C Equipment Notes" (each as defined in the Note Purchase Agreement)
(other than interest becoming due and payable solely as a result of acceleration
of any such "Equipment Notes"); and (v) Owner's pro rata share of 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 (ii), (iii) or (iv) above, (c) Owner's pro rata share of all
compensation and reimbursement of expenses, disbursements and advances payable
by Owner under the Pass Through Trust Agreements, (d) Owner's pro rata share of
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 (e) in the
event Owner requests any amendment to any Operative Agreement or Pass Through
Agreement, Owner's pro rata share of all reasonable fees and expenses
(including, without limitation, fees and disbursements of counsel) of the Escrow
Agents and the Paying Agents in connection therewith payable by the Pass Through
Trustees under the Escrow Agreements. 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 (excluding the Series D Equipment Notes) and
the denominator of which is the aggregate principal balance then outstanding of
all "Equipment Notes" (excluding the "Series D Equipment Notes") (as each such
term is defined in each of 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.

<PAGE>

            The Equipment Notes shall be executed on behalf of the Owner by one
of its authorized officers. Equipment Notes bearing the signatures of
individuals who were at any time the proper officers of the Owner shall bind the
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. The
Owner may from time to time execute and deliver Equipment Notes with respect to
the Aircraft to the Mortgagee for authentication upon original issue and such
Equipment Notes shall thereupon be authenticated and delivered by the Mortgagee
upon the written request of the Owner signed by an authorized officer of the
Owner. 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 Mortgagee by the manual signature of one of
its authorized officers and such certificate upon any Equipment Notes be
conclusive evidence, and the only evidence, that such Equipment Note has been
duly authenticated and delivered hereunder.

            The aggregate Original Amount of the Equipment Notes issued
hereunder shall not exceed the amount set forth as the maximum therefor on
Schedule I hereto.

            SECTION 2.03. [INTENTIONALLY OMITTED]

            SECTION 2.04. METHOD OF PAYMENT

                  (a) The Original 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 12:30 PM, New York time, on the due date of payment to the Mortgagee at the
Corporate Trust Office for distribution among the Note Holders in the manner
provided herein. The 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 Mortgagee 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), all amounts paid by the 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 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 Mortgagee shall fail to make any such payment as provided
in the immediately foregoing sentence after its receipt of funds at the place
and prior to the time specified above, the Mortgagee, in its individual capacity
and not as trustee, agrees to compensate such holders for loss of use of funds
at Debt Rate until such payment is made and the Mortgagee 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 Mortgagee for cancellation
promptly after such payment. Notwithstanding any other provision of this Trust
Indenture to the contrary, the Mortgagee 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 Mortgagee 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

<PAGE>

12:30 PM, New York time, at the place of payment. Prior to the due presentment
for registration of transfer of any Equipment Note, the Owner and the Mortgagee
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 none of the Owner
or the Mortgagee 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 Mortgagee consistent
with this Section 2.04.

                  (b) The Mortgagee, as agent for the Owner, shall exclude and
withhold at the appropriate rate from each payment of Original 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 Mortgagee 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 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) 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
Mortgagee a properly completed, accurate and currently effective U.S. Internal
Revenue Service Form 1001 or W-8 (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 Mortgagee of the withdrawal
or inaccuracy of such form prior to the date of such payment (and the Mortgagee
has no reason to believe that any information set forth in such form is
inaccurate), the Mortgagee shall withhold only the amount, if any, required by
Law (after taking into account any applicable exemptions properly 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. If a Note
Holder (x) which is a Non-U.S. Person has furnished to the Mortgagee a properly
completed, accurate and currently effective U.S. Internal Revenue Service Form
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
properly avoid withholding of United States federal income tax), for each
calendar year in which a payment is made (but prior to the making of any payment
for such year), and has not notified the Mortgagee of the withdrawal or
inaccuracy of such certificate or form prior to the date of such payment (and
the Mortgagee has no reason to believe that any information set forth in such
form is inaccurate) or (y) which is a U.S. Person has furnished to the Mortgagee

<PAGE>

a properly completed, accurate and currently effective U.S. Internal Revenue
Service Form W-9, 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 Mortgagee 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 is 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 Mortgagee 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 Law.

            Owner shall not have any liability for the failure of the Mortgagee
to withhold taxes in the manner provided for herein or for any false, inaccurate
or untrue evidence provided by any Note Holder hereunder.

            SECTION 2.05. APPLICATION OF PAYMENTS

            In the case of each Equipment Note, each payment of Original Amount,
Make-Whole Amount, if any, and interest due thereon shall be applied:

            First: to the payment of accrued interest on such Equipment Note (as
      well as any interest on any overdue Original 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 Original Amount of such Equipment Note
      (or a portion thereof) then due thereunder;

            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 Original Amount of such Equipment Note remaining unpaid (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 Original Amount of such Equipment Note in the inverse order of
their maturity.

            SECTION 2.06. TERMINATION OF INTEREST IN COLLATERAL

            No Note Holder nor any other Indenture Indemnitee shall, as such,
have any further interest in, or other right with respect to, the Collateral
when and if the Original Amount of, Make-Whole Amount, if any, and interest on
and other amounts due under all Equipment Notes held by such Note Holder and all
other sums then due and payable to such Note Holder, such Indenture Indemnitee

<PAGE>

or the Mortgagee hereunder (including, without limitation, under the third
paragraph of Section 2.02 hereof) and under the other Operative Agreements by
the Owner (collectively, the "Secured Obligations") shall have been paid in
full.

            SECTION 2.07. REGISTRATION TRANSFER AND EXCHANGE OF EQUIPMENT NOTES

            The Mortgagee shall keep a register (the "Equipment Note Register")
in which the Mortgagee 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
Mortgagee. The Mortgagee 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 Mortgagee 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
shall execute, and the Mortgagee shall authenticate and deliver, in the name of
the designated transferee or transferees, one or more new Equipment Notes of a
like aggregate Original 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 Original Amount, upon surrender of
the Equipment Notes to be exchanged to the Mortgagee at the Corporate Trust
Office. Whenever any Equipment Notes are so surrendered for exchange, the Owner
shall execute, and the Mortgagee 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 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 Mortgagee) be duly endorsed, or be accompanied by a written instrument of
transfer in form satisfactory to the Mortgagee duly executed by the Note Holder
or such holder's attorney duly authorized in writing, and the Mortgagee 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
Mortgagee shall make a notation on each new Equipment Note of the amount of all
payments of Original 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 Original Amount marked on such new Equipment Note, as
provided above, shall be deemed to have been made thereon. The 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.
The 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
the Owner with respect to such Equipment Note and for all purposes until a

<PAGE>

notice stating otherwise is received from the Mortgagee and such change is
reflected on the Equipment Note Register. The Mortgagee will promptly notify the
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 this Trust Indenture and the Participation Agreement
applicable to Note Holders, including Sections 6.3, 6.4 and 9.1 thereof and
shall be deemed to have covenanted to the parties to the Participation Agreement
as to the matters covenanted by the original Note Holder 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, Mortgagee and Owner shall
use all reasonable efforts to issue new Equipment Notes upon transfer or
exchange within 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 shall, upon the written request of the holder of such
Equipment Note, execute and the Mortgagee shall authenticate and deliver in
replacement thereof a new Equipment Note, payable in the same Original 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 Mortgagee and a photocopy thereof shall be furnished
to the Owner. If the Equipment Note being replaced has been destroyed, lost or
stolen, the holder of such Equipment Note shall furnish to the Owner and the
Mortgagee such security or indemnity as may be required by them to save the
Owner and the Mortgagee harmless and evidence satisfactory to the Owner and the
Mortgagee 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)(1)(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 Owner 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 with the
requirements set forth in this Section 2.08, Mortgagee and Owner shall use all
reasonable efforts to issue new Equipment Notes within 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 Mortgagee, as
Equipment Note Registrar, may require payment 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 Mortgagee shall cancel all Equipment Notes surrendered
for replacement, redemption, transfer, exchange, payment or cancellation and
shall destroy the canceled Equipment Notes.

                  (b) Notice of redemption with respect to the Equipment Notes
shall be given by the Mortgagee by first-class mail, postage prepaid, mailed not
less than 20 nor more than 60 days prior to the applicable redemption date, to
each Note Holder of such Equipment Notes to be redeemed, at such Note Holder's
address appearing in the Equipment Note Register; provided that such notice
shall be revocable by written notice from the Owner to Mortgagee given 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

price.

                  (c) On or before the redemption date, the Owner (or any person
on behalf of the Owner) shall, to the extent an amount equal to the redemption
price for the Equipment Notes to be redeemed on the redemption date shall not
then be held by the Mortgagee, deposit or cause to be deposited with the
Mortgagee by 12:30 PM New York time on the redemption date in immediately

interest. Upon surrender of any such Equipment Note for redemption in accordance
with said notice, such Equipment Note shall be redeemed at the redemption price.
If any Equipment Note called for redemption 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.

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 2.13 or
Article III hereof, it will hold any amount so received in trust for the Senior
Holder (as defined in Section 2.13(c) hereof) and will forthwith turn over such
payment to the Mortgagee in the form received to be applied as provided in

                  (c) As used in this Section 2.13, the term "Senior Holder"

paid in full, (ii) after the Secured Obligations in respect of Series A-1 or
Series A-2 Equipment Notes have been paid in full, the Note Holders of Series B
until the Secured Obligations in respect of Series B Equipment Notes have been

and (B) Liens of the type permitted by clause (iii) above and (y) Owner or
Permitted Lessee, as the case may be, shall have received from the lessor,
mortgagee, secured party or conditional seller, in respect of such airframe, a
written agreement (which may be a copy of the lease, mortgage, security
agreement, conditional sale or other agreement covering such airframe), whereby
such Person agrees that it will not acquire or claim any right, title or

<PAGE>

interest in, or Lien on, such Engine by reason of such Engine being installed on
such airframe at any time while such Engine is subject to the Lien of this Trust
Indenture;

                      (v) Install or permit any Permitted Lessee to install an
Engine on an airframe owned by Owner or such Permitted Lessee, leased to Owner
or such Permitted Lessee, or purchased by Owner or such Permitted Lessee subject
to a conditional sale or other security agreement under circumstances where
neither clause (iii) or (iv) above is applicable; PROVIDED, HOWEVER, that any
such installation shall be deemed an Event of Loss with respect to such Engine,
and Owner shall comply with Section 4.04(e) hereof in respect thereof;

                      (vi) Transfer or permit any Permitted Lessee to transfer
possession of the Aircraft, Airframe or any Engine to the U.S. Government, in
which event Owner shall promptly notify Mortgagee in writing of any such
transfer of possession and, in the case of any transfer pursuant to CRAF, in
such notification shall identify by name, address and telephone numbers the
Contracting Office Representative or Representatives for the Military Airlift
Command of the United States Air Force to whom notices must be given and to whom
requests or claims must be made to the extent applicable under CRAF;

                      (vii) Enter into a charter or Wet Lease or other similar
arrangement with respect to the Aircraft or any other aircraft on which any
Engine may be installed (which shall not be considered a transfer of possession
hereunder); PROVIDED THAT the Owner's obligations hereunder shall continue in
full force and effect notwithstanding any such charter or Wet Lease or other
similar arrangement;

                      (viii) So long as no Event of Default shall have occurred
and be continuing, and subject to the provisions of the immediately following
paragraph, enter into a lease with respect to the Aircraft, Airframe or any
Engine to any Permitted Air Carrier that is not then subject to any bankruptcy,
insolvency, liquidation, reorganization, dissolution or similar proceeding and

Carrier (or, in the case of Taiwan, diplomatic relations at least as good as
those in effect on the Closing Date) and (B) Owner shall have furnished
Mortgagee a favorable opinion of counsel, reasonably satisfactory to Mortgagee,
in the country of domicile of such Permitted Foreign Air Carrier, that (v) the
terms of such lease are the legal, valid and binding obligations of the parties
thereto enforceable under the laws of such jurisdiction, (w) it is not necessary
for Mortgagee to register or qualify to do business in such jurisdiction, if not
already so registered or qualified, as a result, in whole or in part, of the
proposed lease, (x) Mortgagee's Lien in respect of, the Aircraft, Airframe and
Engines will be recognized in such jurisdiction, (y) the Laws of such
jurisdiction of domicile require fair compensation by the government of such
jurisdiction, payable in a currency freely convertible into Dollars, for the
loss of title to the Aircraft, Airframe or Engines in the event of the
requisition by such government of such title (unless Owner shall provide
insurance in the amounts required with respect to hull insurance under this
Trust Indenture covering the requisition of title to the Aircraft, Airframe or
Engines by the government of such jurisdiction so long as the Aircraft, Airframe
or Engines are subject to such lease) and (z) the

<PAGE>

agreement of such Permitted Air Carrier that its rights under the lease are
subject and subordinate to all the terms of this Trust Indenture is enforceable
against such Permitted Air Carrier under applicable law;

PROVIDED that (1) the rights of any transferee who receives possession by reason
of a transfer permitted by this Section 4.02(b) (other than by a transfer of an
Engine which is deemed an Event of Loss) shall be subject and subordinate to all
the terms of this Trust Indenture, (2) the Owner shall remain primarily liable
for the performance of all of the terms of this Trust Indenture and all the
terms and conditions of this Trust Indenture and the other Operative Agreements
shall remain in effect and (3) no lease or transfer of possession otherwise in
compliance with this Section 4.02(b) shall (x) result in any registration or
re-registration of an Aircraft, except to the extent permitted by Section
4.02(e) or the maintenance, operation or use thereof except in compliance with
Sections 4.02(c) and 4.02(d) or (y) permit any action not permitted to the Owner
hereunder.

            In the case of any lease permitted under this Section 4.02(b), the
Owner will include in such lease appropriate provisions which (t) make such
lease expressly subject and subordinate to all of the terms of this Trust
Indenture, including the rights of the Mortgagee to avoid such lease in the
exercise of its rights to repossession of the Airframe and Engines hereunder;
(u) require the Permitted Lessee to comply with the terms of Section 4.06; and
(v) require that the Airframe or any Engine subject thereto be used in

shall be entered into unless (w) Owner shall provide written notice to Mortgagee
(such notice in the event of a lease to a U.S. Air Carrier to be given promptly
after entering into any such lease or, in the case of a lease to any other
Permitted Air Carrier, 10 days in advance of entering into such lease); (x)
Owner shall furnish to Mortgagee evidence reasonably satisfactory to Mortgagee
that the insurance required by Section 4.06 remains in effect; (y) all necessary
documents shall have been duly filed, registered or recorded in such public
offices as may be required fully to preserve the first priority security
interest (subject to Permitted Liens) of Mortgagee in the Aircraft, Airframe and
Engines; and (z) Owner shall reimburse Mortgagee for all of its reasonable
out-of-pocket fees and expenses, including, without limitation, reasonable fees
and disbursements of counsel, incurred by Mortgagee in connection with any such
lease. Except as otherwise provided herein and without in any way relieving the
Owner from its primary obligation for the performance of its obligations under
this Trust Indenture, the Owner may in its sole discretion permit a lessee to
exercise any or all rights which the Owner would be entitled to exercise under
Sections 4.02 and 4.04, and may cause a lessee to perform any or all of the
Owner's obligations under Article IV, and the Mortgagee agrees to accept actual
and full performance thereof by a lessee in lieu of performance by the Owner.

            Mortgagee hereby agrees, and each Note Holder by acceptance of an
Equipment Note agrees, for the benefit of each lessor, conditional seller,
indenture trustee or secured party of any engine leased to, or purchased by,
Owner or any Permitted Lessee subject to a lease, conditional sale, trust
indenture or other security agreement that Mortgagee, each Note Holder and their
respective successors and assigns will not acquire or claim, as against such
lessor, conditional seller, indenture trustee or secured party, any right, title
or interest in any engine as the result of such engine being installed on the
Airframe at any time while such engine is subject to such lease, conditional
sale, trust indenture or other security agreement and owned by such lessor or

<PAGE>

conditional seller or subject to a trust indenture or security interest in favor
of such indenture trustee or secured party.

                  (c) OPERATION AND USE. So long as the Aircraft, Airframe or
any Engine is subject to the Lien of this Trust Indenture, the Owner shall not
operate, use or locate the Aircraft, Airframe or any Engine, or allow the
Aircraft, Airframe or any Engine to be operated, used or located, (i) in any
area excluded from coverage by any insurance required by the terms of Section
4.06, except in the case of a requisition by the U.S. Government where the Owner
obtains indemnity in lieu of such insurance from the U.S. Government, or
insurance from the U.S. Government, against substantially the same risks and for
at least the amounts of the insurance required by Section 4.06 covering such
area, or (ii) in any recognized area of hostilities unless covered in accordance
with Section 4.06 by war risk insurance, or in either case unless the Aircraft,
the Airframe or any Engine is only temporarily operated, used or located in such
area as a result of an emergency, equipment malfunction, navigational error,
hijacking, weather condition or other similar unforeseen circumstance, so long
as Owner diligently and in good faith proceeds to remove the Aircraft from such
area. So long as the Aircraft, the Airframe or any Engine is subject to the Lien
of this Trust Indenture, the Owner shall not permit such Aircraft, Airframe or
any Engine, as the case may be, to be used, operated, maintained, serviced,
repaired or overhauled (x) in violation of any Law binding on or applicable to
such Aircraft, Airframe or Engine or (y) in violation of any airworthiness
certificate, license or registration of any Government Entity relating to the
Aircraft, the Airframe or any Engine, except (i) immaterial or non-recurring
violations with respect to which corrective measures are taken promptly by Owner
or Permitted Lessee, as the case may be, upon discovery thereof, or (ii) to the
extent the validity or application of any such Law or requirement relating to
any such certificate, license or registration is being contested in good faith
by Owner or Permitted Lessee in any reasonable manner which does not involve any
material risk of the sale, forfeiture or loss of the Aircraft, Airframe or any
Engine, any material risk of criminal liability or material civil penalty
against Mortgagee or impair the Mortgagee's security interest in the Aircraft,
Airframe or any Engine.

                  (d) MAINTENANCE AND REPAIR. So long as the Aircraft, Airframe
or any Engine is subject to the Lien of this Trust Indenture, the Owner shall
cause the Aircraft, Airframe and each Engine to be maintained, serviced,
repaired and overhauled in accordance with (i) maintenance standards required by
or substantially equivalent to those required by the FAA or the central aviation
authority of Canada, France, Germany, Japan, the Netherlands or the United
Kingdom for the Aircraft, Airframe and Engines, so as to (A) keep the Aircraft,
the Airframe and each Engine in as good operating condition as on the Closing
Date, ordinary wear and tear excepted, (B) keep the Aircraft in such operating
condition as may be necessary to enable the applicable airworthiness
certification of such Aircraft to be maintained under the regulations of the FAA
or other Aviation Authority then having jurisdiction over the operation of the
Aircraft, except during (x) temporary periods of storage in accordance with
applicable regulations, (y) maintenance and modification permitted hereunder or
(z) periods when the FAA or such other Aviation Authority has revoked or
suspended the airworthiness certificates for Similar Aircraft; and (ii) except
during periods when a Permitted Lease is in effect, the same standards as Owner
uses with respect to similar aircraft of similar size in its fleet operated by
Owner in similar circumstances and, during any period in which a Permitted Lease
is in effect, the same standards used by the Permitted Lessee with respect to
similar aircraft of similar size in its fleet and operated by the Permitted
Lessee in similar circumstances. Owner further agrees that the Aircraft,

<PAGE>

Airframe and Engines will be maintained, used, serviced, repaired, overhauled or
inspected in compliance with applicable Laws with respect to the maintenance of
the Aircraft and in compliance with each applicable airworthiness certificate,
license and registration relating to the Aircraft, Airframe or any Engine issued
by the Aviation Authority, other than minor or nonrecurring violations with
respect to which corrective measures are taken upon discovery thereof and except
to the extent Owner or Permitted Lessee is contesting in good faith the validity
or application of any such Law or requirement relating to any such certificate,
license or registration in any reasonable manner which does not create a
material risk of sale, loss or forfeiture of the Aircraft, the Airframe or any
Engine or the interest of Mortgagee therein, or any material risk of criminal
liability or material civil penalty against Mortgagee. The Owner shall maintain
or cause to be maintained the Aircraft Documents in the English language.

                  (e) REGISTRATION. The Owner on or prior to the date of the
Closing shall cause the Aircraft to be duly registered in its name under the Act
and except as otherwise permitted by this Section 4.02(e) at all times
thereafter shall cause the Aircraft to remain so registered. So long as no
Special Default or Event of Default shall have occurred and be continuing, Owner
may, by written notice to Mortgagee, request to change the country of
registration of the Aircraft. Any such change in registration shall be effected
only in compliance with, and subject to all of the conditions set forth in,
Section 6.4.5 of the Participation Agreement. Unless the Trust Indenture has
been discharged, Owner shall also cause the Trust Indenture to be duly recorded
and at all times maintained of record as a first-priority perfected mortgage
(subject to Permitted Liens) on the Aircraft, the Airframe and each of the
Engines (except to the extent such perfection or priority cannot be maintained
solely as a result of the failure by Mortgagee to execute and deliver any
necessary documents).

                  (f) MARKINGS. If permitted by applicable Law, on or reasonably
promptly after the Closing Date, Owner will cause to be affixed to, and
maintained in, the cockpit of the Airframe and on each Engine, in each case, in
a clearly visible location, a placard of a reasonable size and shape bearing the
legend: "Subject to a security interest in favor of Wilmington Trust Company,
not in its individual capacity but solely as Mortgagee." Such placards may be
removed temporarily, if necessary, in the course of maintenance of the Airframe
or Engines. If any such placard is damaged or becomes illegible, Owner shall
promptly replace it with a placard complying with the requirements of this
Section.

            SECTION 4.03. INSPECTION

                  (a) At all reasonable times, so long as the Aircraft is
subject to the Lien of this Trust Indenture, Mortgagee and its authorized
representatives (the "Inspecting Parties") may (not more than once every 12
months unless an Event of Default has occurred and is continuing then such
inspection right shall not be so limited) inspect the Aircraft, Airframe and
Engines (including without limitation, the Aircraft Documents) and any such
Inspecting Party may make copies of such Aircraft Documents not reasonably
deemed confidential by Owner or such Permitted Lessee.

                  (b) Any inspection of the Aircraft hereunder shall be limited
to a visual, walk-around inspection and shall not include the opening of any

<PAGE>

panels, bays or other components of the Aircraft, and no such inspection shall
interfere with Owner's or any Permitted Lessee's maintenance and operation of
the Aircraft, Airframe and Engines.

                  (c) With respect to such rights of inspection, Mortgagee shall
not have any duty or liability to make, or any duty or liability by reason of
not making, any such visit, inspection or survey.

                  (d) Each Inspecting Party shall bear its own expenses in
connection with any such inspection (including the cost of any copies made in
accordance with Section 4.03(a)).

            SECTION 4.04. REPLACEMENT AND POOLING OF PARTS, ALTERATIONS,
MODIFICATIONS AND ADDITIONS; SUBSTITUTION OF ENGINES

                  (a) REPLACEMENT OF PARTS. Except as otherwise provided herein,
so long as the Airframe or Engine is subject to the Lien of this Indenture,
Owner, at its own cost and expense, will, or will cause a Permitted Lessee to,
at its own cost and expense, promptly replace (or cause to be replaced) all
Parts which may from time to time be incorporated or installed in or attached to
the Aircraft, 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. In addition, Owner
may, at its own cost and expense, or may permit a Permitted Lessee at its own
cost and expense to, remove (or cause to be removed) 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, HOWEVER, that Owner, except as
otherwise provided herein, at its own cost and expense, will, or will cause a
Permitted Lessee at its own cost and expense to, 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
Section 4.04(c) below (and except in the case of replacement property
temporarily installed on an emergency basis) and shall be in good operating
condition and have a value and utility not less than the value and utility of
the Parts replaced (assuming such replaced Parts were in the condition required
hereunder).

                  (b) PARTS. Except as otherwise provided herein, any Part at
any time removed from the Airframe or any Engine shall remain subject to the
Lien of this Trust Indenture, no matter where located, until such time as such
Part shall be replaced by a Part that has been incorporated or installed in or
attached to such Airframe or any Engine and that meets the requirements for
replacement Parts specified above. Immediately upon any replacement Part
becoming incorporated or installed in or attached to such Airframe or any Engine
as provided in Section 4.04(a), without further act, (i) the replaced Part shall
thereupon be free and clear of all rights of the Mortgagee and shall no longer
be deemed a Part hereunder, and (ii) such replacement Part shall become subject
to this Trust Indenture and be deemed part of such Airframe or any Engine, as
the case may be, for all purposes hereof to the same extent as the Parts
originally incorporated or installed in or attached to such Airframe or any
Engine.

                  (c) POOLING OF PARTS. Any Part removed from the Aircraft,
Airframe or an Engine may be subjected by the Owner or a Permitted Lessee to a

<PAGE>

normal pooling arrangement customary in the airline industry and entered into in
the ordinary course of business of Owner or Permitted Lessee, provided that the
part replacing such removed Part shall be incorporated or installed in or
attached to such Airframe or any Engine in accordance with Sections 4.04(a) and
4.04(b) 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 may be owned by any third party, subject to a normal
pooling arrangement, so long as the Owner or a Permitted Lessee, at its own cost
and expense, as promptly thereafter as reasonably possible, either (i) causes
such replacement part to become subject to the Lien of this Trust Indenture,
free and clear of all Liens except Permitted Liens, at which time such
replacement part shall become a Part or (ii) replaces (or causes to be replaced)
such replacement part by incorporating or installing in or attaching to the
Aircraft, Airframe or any Engine a further replacement Part owned by the Owner
free and clear of all Liens except Permitted Liens and which shall become
subject to the Lien of this Trust Indenture in accordance with Section 4.04(b).

                  (d) ALTERATIONS, MODIFICATIONS AND ADDITIONS. The Owner shall,
or shall cause a Permitted Lessee to, make (or cause to be made) alterations and
modifications in and additions to the Aircraft, Airframe and each Engine as may
be required to be made from time to time to meet the applicable standards of the
FAA or other Aviation Authority having jurisdiction over the operation of the
Aircraft, to the extent made mandatory in respect of the Aircraft (a "Mandatory
Modification"); PROVIDED HOWEVER, that the Owner or a Permitted Lessee may, in
good faith and by appropriate procedure, contest the validity or application of
any law, rule, regulation or order in any reasonable manner which does not
materially adversely affect Mortgagee's interest in the Aircraft and does not
involve any material risk of sale, forfeiture or loss of the Aircraft or the
interest of Mortgagee therein, or any material risk of material civil penalty or
any material risk of criminal liability being imposed on Mortgagee or the holder
of any Equipment Note. In addition, the Owner, at its own expense, may, or may
permit a Permitted Lessee at its own cost and expense to, from time to time make
or cause to be made such alterations and modifications in and additions to the
Airframe or any Engine (each an "Optional Modification") as the Owner or such
Permitted Lessee may deem desirable in the proper conduct of its business
including, without limitation, removal of Parts which Owner deems are obsolete
or no longer suitable or appropriate for use in the Aircraft, Airframe or such
Engine; PROVIDED, HOWEVER, that no such Optional Modification shall (i)
materially diminish the fair market value, utility, or useful life of the
Aircraft or any Engine below its fair market value, utility or useful life
immediately prior to such Optional Modification (assuming the Aircraft or such
Engine was in the condition required by the Trust Indenture immediately prior to
such Optional Modification) or (ii) cause the Aircraft to cease to have the
applicable standard certificate of airworthiness. All Parts incorporated or
installed in or attached to any Airframe or any Engine as the result of any
alteration, modification or addition effected by the Owner shall be free and
clear of any Liens except Permitted Liens and become subject to the Lien of this
Trust Indenture; PROVIDED that the Owner or any Permitted Lessee may, at any
time so long as the Airframe or any Engine is subject to the Lien of this Trust
Indenture, remove any such Part (such Part being referred to herein as a
"REMOVABLE PART") from such Airframe or an Engine if (i) such Part is in
addition to, and not in replacement of or in substitution for, any Part
originally incorporated or installed in or attached to such Airframe or any
Engine at the time of delivery thereof hereunder or any Part in replacement of,
or in substitution for, any such original Part, (ii) such Part is not required
to be incorporated or installed in or attached or added to such Airframe or any

<PAGE>

Engine pursuant to the terms of Section 4.02(d) or the first sentence of this
Section 4.04(d) and (iii) such Part can be removed from such Airframe or any
Engine without materially diminishing the fair market value, utility or
remaining useful life which such Airframe or any Engine would have had at the
time of removal had such removal not been effected by the Owner, assuming the
Aircraft was otherwise maintained in the condition required by this Trust
Indenture and such Removable Part had not been incorporated or installed in or
attached to the Aircraft, Airframe or such Engine. Upon the removal by the Owner
of any such Part as above provided, title thereto shall, without further act, be
free and clear of all rights of the Mortgagee and such Part shall no longer be
deemed a Part hereunder. Removable Parts may be leased from or financed by third
parties other than Mortgagee.

                  (e) SUBSTITUTION OF ENGINES. Upon the occurrence of an Event
of Loss with respect to an Engine under circumstances in which an Event of Loss
with respect to the Airframe has not occurred, Owner shall promptly (and in any
event within 15 days after such occurrence) give the Mortgagee written notice of
such Event of Loss. The Owner shall have the right at its option at any time, on
at least 5 Business Days' prior notice to the Mortgagee, to substitute, and if
an Event of Loss shall have occurred with respect to an Engine under
circumstances in which an Event of Loss with respect to the Airframe has not
occurred, shall within 60 days of the occurrence of such Event of Loss
substitute, a Replacement Engine for any Engine. In such event, immediately upon
the effectiveness of such substitution and without further act, (i) the replaced
Engine shall thereupon be free and clear of all rights of the Mortgagee and the
Lien of this Trust Indenture and shall no longer be deemed an Engine hereunder
and (ii) such Replacement Engine shall become subject to this Trust Indenture
and be deemed part of the Aircraft for all purposes hereof to the same extent as
the replaced Engine. Such Replacement Engine shall be an engine manufactured by
Engine Manufacturer that is the same model as the Engine to be replaced thereby,
or an improved model, and that is suitable for installation and use on the
Airframe, and that has a value, utility and remaining useful life (without
regard to hours and cycles remaining until overhaul) at least equal to the
Engine to be replaced thereby (assuming that such Engine had been maintained in
accordance with this Trust Indenture). The Owner's right to make a replacement
hereunder shall be subject to the fulfillment (which may be simultaneous with
such replacement) of the following conditions precedent at the Owner's sole cost
and expense, and the Mortgagee agrees to cooperate with the Owner to the extent
necessary to enable it to timely satisfy such conditions:

                      (i) an executed counterpart of each of the following
documents shall be delivered to the Mortgagee:

                  (A) a Trust Indenture Supplement covering the Replacement
            Engine, which shall have been duly filed for recordation pursuant to
            the Act or such other applicable law of the jurisdiction other than
            the United States in which the Aircraft of which such Engine is a
            part is registered in accordance with Section 4.02(e), as the case
            may be;

                  (B) a full warranty bill of sale (as to title), covering the
            Replacement Engine, executed by the former owner thereof in favor of
            the Owner (or, at the Owner's option, other evidence of the Owner's
            ownership of such Replacement Engine, reasonably satisfactory to the
            Mortgagee); and

<PAGE>

                  (C) UCC financing statements covering the security interests
            created by this Trust Indenture (or any similar statements or other
            documents required to be filed or delivered pursuant to the laws of
            the jurisdiction in which such Aircraft may be registered) as are
            deemed necessary or desirable by counsel for the Mortgagee to
            protect the security interests of the Mortgagee in the Replacement
            Engine;

                      (ii) the Owner shall cause to be delivered to the
Mortgagee an opinion of counsel to the effect that the Lien of this Trust
Indenture continues to be in full force and effect with respect to the
Replacement Engine and such evidence of compliance with the insurance provisions
of Section 4.06 with respect to such Replacement Engine as Mortgagee shall
reasonably request;

                      (iii) the Owner shall have furnished to Mortgagee an
opinion of Owner's aviation law counsel reasonably satisfactory to Mortgagee and
addressed to Mortgagee as to the due filing for recordation of the Trust
Indenture Supplement with respect to such Replacement Engine under the Act or
such other applicable law of the jurisdiction other than the United States in
which the Aircraft is registered in accordance with Section 4.02(e), as the case
may be; and

                      (iv) the Owner shall have furnished to Mortgagee a
certificate of a qualified aircraft engineer (who may be an employee of Owner)
certifying that such Replacement Engine has a value and utility and remaining
useful life (without regard to hours and cycles remaining until overhaul) at
least equal to the Engine so replaced (assuming that such Engine had been
maintained in accordance with this Trust Indenture). Upon satisfaction of all
conditions to such substitution, (x) the Mortgagee shall execute and deliver to
the Owner such documents and instruments, prepared at the Owner's expense, as
the Owner shall reasonably request to evidence the release of such replaced
Engine from the Lien of this Trust Indenture, (y) the Mortgagee shall assign to
the Owner all claims it may have against any other Person relating to any Event
of Loss giving rise to such substitution and (z) the Owner shall receive all
insurance proceeds (other than those reserved to others under Section 4.06(b))
and proceeds in respect of any Event of Loss giving rise to such replacement to
the extent not previously applied to the purchase price of the Replacement
Engine as provided in Section 4.05(d).

            SECTION 4.05. LOSS, DESTRUCTION OR REQUISITION

                      (a) EVENT OF LOSS WITH RESPECT TO THE AIRFRAME.

            Upon the occurrence of an Event of Loss with respect to the
Airframe, the Owner shall promptly (and in any event within 15 days after such
occurrence) give the Mortgagee written notice of such Event of Loss. The Owner
shall, within 45 days after such occurrence, give the Mortgagee written notice
of Owner's election to either replace the Airframe as provided under Section
4.05(a)(i) or to make payment in respect of such Event of Loss as provided under
Section 4.05(a)(ii) (it being agreed that if Owner shall not have given the
Mortgagee such notice of such election within the above specified time period,
the Owner shall be deemed to have elected to make payment in respect of such
Event of Loss as provided under Section 4.05(a)(ii)):

<PAGE>

                        (i) if Owner elects to replace the Airframe, Owner
shall, subject to the satisfaction of the conditions contained in Section
4.05(c), as promptly as possible and in any event within 120 days after the
occurrence of such Event of Loss, cause to be subjected to the Lien of this
Trust Indenture, in replacement of the Airframe with respect to which the Event
of Loss occurred, a Replacement Airframe and, if any Engine shall have been
installed on the Airframe when it suffered the Event of Loss, a Replacement
Engine therefor, such Replacement Airframe and Replacement Engines to be free
and clear of all Liens except Permitted Liens and to have a value, utility and
remaining useful life (without regard to hours or cycles remaining until the
next regular maintenance check) at least equal to the Airframe or Engine, as the
case may be, to be replaced thereby (assuming that such Airframe or Engine had
been maintained in accordance with this Trust Indenture); PROVIDED THAT if the
Owner shall not perform its obligation to effect such replacement under this
clause (i) during the 120-day period of time provided herein, it shall pay the
amounts required to be paid pursuant to and within the time frame specified in
clause (ii) below; or

                        (ii) if Owner elects to make a payment in respect of
such Event of Loss of the Airframe, Owner shall make a payment to the Mortgagee
for purposes of redeeming Equipment Notes in accordance with Section 2.10 hereof
on a date on or before the Business Day next following the earlier of (x) the
120th day following the date of the occurrence of such Event of Loss, and (y)
the fourth Business Day following the receipt of insurance proceeds with respect
to such Event of Loss (but in any event not earlier than the date of Owner's
election under Section 4.05(a) to make payment under this Section 4.05 (a)(ii));
and upon such payment and payment of all other Secured Obligations then due and
payable, the Mortgagee shall, at the cost and expense of the Owner, release from
the Lien of this Trust Indenture the Airframe and the Engines, by executing and
delivering to the Owner all documents and instruments as the Owner may
reasonably request to evidence such release.

                  (b) EFFECT OF REPLACEMENT. Should the Owner have provided a
Replacement Airframe and Replacement Engines, if any, as provided for in Section
4.05(a)(i), (i) the Lien of this Trust Indenture shall continue with respect to
such Replacement Airframe and Replacement Engines, if any, as though no Event of
Loss had occurred; (ii) the Mortgagee shall, at the cost and expense of the
Owner, release from the Lien of this Trust Indenture the replaced Airframe and
Engines, if any, by executing and delivering to the Owner such documents and
instruments as the Owner may reasonably request to evidence such release; and
(iii) in the case of a replacement upon an Event of Loss, the Mortgagee shall
assign to the Owner all claims the Mortgagee may have against any other Person
arising from the Event of Loss and the Owner shall receive all insurance
proceeds (other than those reserved to others under Section 4.06(b)) and
proceeds from any award in respect of condemnation, confiscation, seizure or
requisition, including any investment interest thereon, to the extent not
previously applied to the purchase price of the Replacement Airframe and
Replacement Engines, if any, as provided in Section 4.05(d).

                  (c) CONDITIONS TO AIRFRAME AND ENGINE REPLACEMENT. The Owner's
right to substitute a Replacement Airframe and Replacement Engines, if any, as
provided in Section 4.05(a)(i) shall be subject to the fulfillment, at the
Owner's sole cost and expense, in addition to the conditions contained in such
Section 4.05(a)(i), of the following conditions precedent:

<PAGE>

                        (i) on the date when the Replacement Airframe and
Replacement Engines, if any, is subjected to the Lien of this Trust Indenture

Date"), an executed counterpart of each of the following documents (or, in the
case of the FAA Bill of Sale and full warranty bill of sale referred to below, a
photocopy thereof) shall have been delivered to the Mortgagee:

                  (A) a Trust Indenture Supplement covering the Replacement

            law of such jurisdiction other than the United States in which the
            Replacement Airframe and Replacement Engines, if any, are to be
            registered in accordance with Section 4.02(e), as the case may be;

                  (B) an FAA Bill of Sale (or a comparable document, if any, of
            another Aviation Authority, if applicable) covering the Replacement
            Airframe and Replacement Engines, if any, executed by the former
            owner thereof in favor of the Owner;

                  (C) a full warranty (as to title) bill of sale, covering the
            Replacement Airframe and Replacement Engines, if any, executed by
            the former owner thereof in favor of the Owner (or, at the Owner's
            option, other evidence of the Owner's ownership of such Replacement
            Airframe and Replacement Engines, if any, reasonably satisfactory to
            the Mortgagee); and

                  (D) UCC financing statements (or any similar statements or
            other documents required to be filed or delivered pursuant to the
            laws of the jurisdiction in which the Replacement Airframe and
            Replacement Engines, if any, may be registered in accordance with
            Section 4.02(e)) as are deemed necessary or desirable by counsel for
            the Mortgagee to protect the security interests of the Mortgagee in
            the Replacement Airframe and Replacement Engines, if any;

                        (ii) the Replacement Airframe and Replacement Engines,
if any, shall be of the same model as the Airframe or Engines, as the case may
be, or an improved model of such aircraft or engines of the manufacturer
thereof, shall have a value and utility (without regard to hours or cycles
remaining until the next regular maintenance check) at least equal to, and be in
as good operating condition and repair as, the Airframe and any Engines replaced
(assuming such Airframe and Engines had been maintained in accordance with this
Trust Indenture);

                        (iii) the Mortgagee (acting directly or by authorization
to its special counsel) shall have received satisfactory evidence as to the
compliance with Section 4.06 with respect to the Replacement Airframe and
Replacement Engines, if any;

                        (iv) on the Replacement Closing Date, (A) the Owner
shall cause the Replacement Airframe and Replacement Engines, if any, to be
subject to the Lien of this Trust Indenture free and clear of Liens (other than
Permitted Liens), (B) the Replacement Airframe shall have been duly certified by
the FAA as to type and airworthiness in accordance with the terms of this Trust
Indenture and (C) application for registration of the Replacement Airframe in
accordance with Section 4.02(e) shall have been duly made with the FAA or other

<PAGE>

applicable Aviation Authority and the Owner shall have authority to operate the
Replacement Airframe;

                        (v) the Mortgagee at the expense of the Owner, shall
have received (acting directly or by authorization to its special counsel) (A)
an opinion of counsel, addressed to the Mortgagee, to the effect that the
Replacement Airframe and Replacement Engine, if any, has or have duly been made
subject to the Lien of this Trust Indenture, and Mortgagee will be entitled to
the benefits of Section 1110 with respect to the Replacement Airframe, provided
that such opinion with respect to Section 1110 need not be delivered to the
extent that immediately prior to such replacement the benefits of Section 1110
were not, solely by reason of a change in law or court interpretation thereof,
available to Mortgagee, and (B) an opinion of Owner's aviation law counsel
reasonably satisfactory to and addressed to Mortgagee as to the due registration
of any such Replacement Airframe and the due filing for recordation of each
Trust Indenture Supplement with respect to such Replacement Airframe or
Replacement Engine under the Act or such other applicable law of the
jurisdiction other than the United States in which the Replacement Airframe is
to be registered in accordance with Section 4.02(e), as the case may be; and

                        (vi) the Owner shall have furnished to the Mortgagee a
certificate of a qualified aircraft engineer (who may be an employee of Owner)
certifying that the Replacement Airframe and Replacement Engines, if any, have a
value and utility and remaining useful life (without regard to hours and cycles
remaining until overhaul) at least equal to the Airframe and any Engines so
replaced (assuming that such Airframe and Engines had been maintained in
accordance with this Trust Indenture).

                  (d) NON-INSURANCE PAYMENTS RECEIVED ON ACCOUNT OF AN EVENT OF
LOSS. Any amounts, other than insurance proceeds in respect of damage or loss
not constituting an Event of Loss (the application of which is provided for in
Annex B), received at any time by Mortgagee or Owner from any Government Entity
or any other Person in respect of any Event of Loss will be applied as follows:

                  (i) If such amounts are received with respect to the Airframe,
            and any Engine installed thereon at the time of such Event of Loss,
            upon compliance by Owner with the applicable terms of Section
            4.05(c) with respect to the Event of Loss for which such amounts are
            received, such amounts shall be paid over to, or retained by, Owner;

                  (ii) If such amounts are received with respect to an Engine
            (other than an Engine installed on the Airframe at the time such
            Airframe suffers an Event of Loss), upon compliance by Owner with
            the applicable terms of Section 4.04(e) with respect to the Event of
            Loss for which such amounts are received, such amounts shall be paid
            over to, or retained by, Owner;

                  (iii) If such amounts are received, in whole or in part, with
            respect to the Airframe, and Owner makes, has made or is deemed to
            have made the election set forth in Section 4.05(a)(ii), such
            amounts shall be applied as follows:

<PAGE>

                      FIRST, if the sum described in Section 4.05(a)(ii) has not
                      then been paid in full by Owner, such amounts shall be
                      paid to Mortgagee to the extent necessary to pay in full
                      such sum; and

                      SECOND, the remainder, if any, shall be paid to Owner.

                  (e) REQUISITION FOR USE. In the event of a requisition for use
by any Government Entity of the Airframe and the Engines, if any, or engines
installed on such Airframe while such Airframe is subject to the Lien of this
Trust Indenture, the Owner shall promptly notify the Mortgagee of such
requisition and all of the Owner's obligations under this Trust Indenture shall
continue to the same extent as if such requisition had not occurred except to
the extent that the performance or observance of any obligation by the Owner
shall have been prevented or delayed by such requisition; PROVIDED THAT the
Owner's obligations under this Section 4.05 with respect to the occurrence of an
Event of Loss for the payment of money and under Section 4.06 (except while an
assumption of liability by the U.S. Government of the scope referred to in
Section 4.02(c) is in effect) shall not be reduced or delayed by such
requisition. Any payments received by the Mortgagee or the Owner or Permitted
Lessee from such Government Entity with respect to such requisition of use shall
be paid over to, or retained by, the Owner. In the event of an Event of Loss of
an Engine resulting from the requisition for use by a Government Entity of such
Engine (but not the Airframe), the Owner will replace such Engine hereunder by
complying with the terms of Section 4.04(e) and any payments received by the
Mortgagee or the Owner from such Government Entity with respect to such
requisition shall be paid over to, or retained by, the Owner.

                  (f) CERTAIN PAYMENTS TO BE HELD AS SECURITY. Any amount
referred to in this Section 4.05 or Section 4.06 which is payable or creditable
to, or retainable by, the Owner shall not be paid or credited to, or retained by
the Owner if at the time of such payment, credit or retention a Special Default
or an Event of Default shall have occurred and be continuing, but shall be paid
to and held by the Mortgagee as security for the obligations of the Owner under
this Trust Indenture and the Operative Agreements, and at such time as there
shall not be continuing any such Special Default or Event of Default such amount
and any gain realized as a result of investments required to be made pursuant to
Section 6.06 shall to the extent not theretofore applied as provided herein, be
paid over to the Owner.

            SECTION 4.06. INSURANCE

                  (a) OWNER'S OBLIGATION TO INSURE. Owner shall comply with, or
cause to be complied with, each of the provisions of Annex B, which provisions
are hereby incorporated by this reference as if set forth in full herein.

                  (b) INSURANCE FOR OWN ACCOUNT. Nothing in Section 4.06 shall
limit or prohibit (a) Owner from maintaining the policies of insurance required
under Annex B with higher limits than those specified in Annex B, or (b)
Mortgagee from obtaining insurance for its own account (and any proceeds payable
under such separate insurance shall be payable as provided in the policy
relating thereto); PROVIDED, HOWEVER, that no insurance may be obtained or
maintained that would limit or otherwise adversely affect the coverage of any
insurance required to be obtained or maintained by Owner pursuant to this
Section 4.06 and Annex B.

<PAGE>

                  (c) INDEMNIFICATION BY GOVERNMENT IN LIEU OF INSURANCE.
Mortgagee agrees to accept, in lieu of insurance against any risk with respect
to the Aircraft described in Annex B, indemnification from, or insurance
provided by, the U.S. Government, or upon the written consent of Mortgagee,
other Government Entity, against such risk in an amount that, when added to the
amount of insurance (including permitted self-insurance), if any, against such
risk that Owner (or any Permitted Lessee) may continue to maintain, in
accordance with this Section 4.06, during the period of such requisition or
transfer, shall be at least equal to the amount of insurance against such risk
otherwise required by this Section 4.06.

                  (d) APPLICATION OF INSURANCE PROCEEDS. As between Owner and
Mortgagee, all insurance proceeds received as a result of the occurrence of an
Event of Loss with respect to the Aircraft or any Engine under policies required
to be maintained by Owner pursuant to this Section 4.06 will be applied in
accordance with Section 4.05(d). All proceeds of insurance required to be
maintained by Owner, in accordance with Section 4.06 and Section B of Annex B,
in respect of any property damage or loss not constituting an Event of Loss with
respect to the Aircraft, Airframe or any Engine will be applied in payment (or
to reimburse Owner) for repairs or for replacement property, and any balance
remaining after such repairs or replacement with respect to such damage or loss
shall be paid over to, or retained by, Owner.

            SECTION 4.07. MERGER OF OWNER

                  (a) IN GENERAL. Owner shall not consolidate with or merge into
any other person under circumstances in which Owner is not the surviving
corporation, or convey, transfer or lease in one or more transactions all or
substantially all of its assets to any other person, unless:

                      (i) such person is organized, existing and in good
standing under the Laws of the United States, any State of the United States or
the District of Columbia and, upon consummation of such transaction, such person
will be a U.S. Air Carrier;

                      (ii) such person executes and delivers to Mortgagee a duly
authorized, legal, valid, binding and enforceable agreement, reasonably
satisfactory in form and substance to Mortgagee, containing an effective
assumption by such person of the due and punctual performance and observance of
each covenant, agreement and condition in the Operative Agreements to be
performed or observed by Owner;

                      (iii) such person makes such filings and recordings with
the FAA pursuant to the Act as shall be necessary to evidence such consolidation
or merger; and

                      (iv) immediately after giving effect to such consolidation
or merger no Event of Default shall have occurred and be continuing.

                  (b) EFFECT OF MERGER. Upon any such consolidation or merger of
Owner with or into, or the conveyance, transfer or lease by Owner of all or
substantially all of its assets to, any Person in accordance with this Section
4.07, such Person will succeed to, and be substituted for, and may exercise
every right and power of, Owner under the Operative Agreements with the same
effect as if such person had been named as "Owner" therein. No such
consolidation or merger, or conveyance, transfer or lease, shall have the effect

<PAGE>

of releasing Owner or such Person from any of the obligations, liabilities,
covenants or undertakings of Owner under the Trust Indenture.

                                    ARTICLE V

in compliance with any judgment, decree or order of any court or any order, rule
or regulation of any administrative or governmental body):

                        (i) the failure of the Owner to pay (i) principal of,

period in excess of 10 Business Days after Owner has received written notice
from Mortgagee of the failure to make such payment when due;

                        (ii) Owner shall fail to carry and maintain, or cause to
be carried and maintained, insurance on and in respect of the Aircraft, Airframe
and Engines in accordance with the provisions of Section 4.06;

                        (iii) Owner shall fail to observe or perform (or caused
to be observed and performed) in any material respect any other covenant,
agreement or obligation set forth herein or in any other Operative Agreement to
which Owner is a party and such failure shall continue unremedied for a period
of 30 days from and after the date of written notice thereof to Owner from
Mortgagee, unless such failure is capable of being corrected and Owner shall be
diligently proceeding to correct such failure, in which case there shall be no
Event of Default unless and until such failure shall continue unremedied for a
period of 270 days after receipt of such notice;

                        (iv) any representation or warranty made by Owner
herein, in the Participation Agreement or in any other Operative Agreement to
which Owner is a party (a) shall prove to have been untrue or inaccurate in any
material respect as of the date made, (b) such untrue or inaccurate
representation or warranty is material at the time in question, (c) and the same
shall remain uncured (to the extent of the adverse impact of such incorrectness
on the interest of the Mortgagee) for a period in excess of 30 days from and
after the date of written notice thereof from Mortgagee to Owner;

                        (v) the Owner shall consent to the appointment of or
taking possession by a receiver, trustee or liquidator of itself or of a
substantial part of its property, or the Owner shall admit in writing its
inability to pay its debts generally as they come due or shall make a general
assignment for the benefit of its creditors, or the Owner shall file a voluntary
petition in bankruptcy or a voluntary petition or an answer seeking
reorganization, liquidation or other relief under any bankruptcy laws or
insolvency laws (as in effect at such time), or an answer admitting the material

<PAGE>

allegations of a petition filed against it in any such case, or the Owner shall
seek relief by voluntary petition, answer or consent, under the provisions of
any other bankruptcy or similar law providing for the reorganization or
winding-up of corporations (as in effect at such time), or the Owner shall seek
an agreement, composition, extension or adjustment with its creditors under such
laws or the Owner's board of directors shall adopt a resolution authorizing
corporate action in furtherance of any of the foregoing;

                        (vi) an order, judgment or decree shall be entered by
any court of competent jurisdiction appointing, without the consent of the
Owner, a receiver, trustee or liquidator of the Owner or of any substantial part
of its property, or any substantial part of the property of the Owner shall be
sequestered, or granting any other relief in respect of the Owner as a debtor
under any bankruptcy laws or other insolvency laws (as in effect at such time),
and any such order, judgment, decree, or decree of appointment or sequestration

after the date of entry thereof; or

                        (vii) a petition against the Owner in a proceeding under
any bankruptcy laws or other insolvency laws (as in effect at such time) is
filed and not withdrawn or dismissed within 90 days thereafter, or if, under the
provisions of any law providing for reorganization or winding-up of corporations
which may apply to the Owner, any court of competent jurisdiction shall assume
jurisdiction, custody or control of the Owner of any substantial part of its
property and such jurisdiction, custody or control shall remain in force
unrelinquished, unstayed or unterminated for a period of 90 days.

            SECTION 5.02. 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 Mortgagee may exercise any or all of the rights and powers and
pursue any and all of the remedies pursuant to this Article V and shall have and
may exercise all of the rights and remedies of a secured party under the Uniform
Commercial Code 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 and all persons claiming under it wholly or partly
therefrom; PROVIDED, that the Mortgagee shall give the Owner twenty days' prior
written notice of its intention to sell the Aircraft. Without limiting any of
the foregoing, it is understood and agreed that the Mortgagee 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 Mortgagee 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 the Owner,
declare all the Equipment Notes to be due and payable, whereupon the unpaid
Original Amount of all Equipment Notes then outstanding, together with accrued
but unpaid interest thereon (without Make-Whole Amount) and other amounts due
thereunder or otherwise payable hereunder, 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 (v), (vi) or
(vii) of Section 5.01 hereof shall have occurred, then and in every such case
the unpaid Original Amount then outstanding, together with accrued but unpaid

<PAGE>

interest and all other amounts due hereunder and under the Equipment Notes shall
immediately and without further act become due and payable without presentment,
demand, protest or notice, all of which are hereby waived.

            This Section 5.02(b), however, is subject to the condition that, if
at any time after the Original 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 hereunder or under the
Equipment Notes (except the Original 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 Mortgagee, rescind and annul the Mortgagee's
declaration (or such automatic acceleration) 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) The Note Holders shall be entitled, at any sale pursuant
to this Section 5.02, 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 (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 Collateral, 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 Original Amount of all Equipment Notes then outstanding, together with
accrued 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.

                  (e) Notwithstanding anything contained herein, so long as the
Pass Through Trustee under any Pass Through Trust Agreement (or its designee) is
a Note Holder, the Mortgagee will not be authorized or empowered to acquire
title to any Collateral or take any action with respect to any Collateral so
acquired by it if such acquisition or action would cause any Trust to fail to
qualify as a "grantor trust" for federal income tax purposes.

            SECTION 5.03. RETURN OF AIRCRAFT, ETC.

                  (a) If an Event of Default shall have occurred and be
continuing and the Equipment Notes have been accelerated, at the request of the
Mortgagee, the Owner shall promptly execute and deliver to the Mortgagee such
instruments of title and other documents as the Mortgagee may deem necessary or
advisable to enable the Mortgagee or an agent or representative designated by
the Mortgagee, at such time or times and place or places as the Mortgagee may
specify, to obtain possession of all or any part of the Collateral to which the
Mortgagee shall at the time be entitled hereunder. If the Owner shall for any
reason fail to execute and deliver such instruments and documents after such
request by the Mortgagee, the Mortgagee may (i) obtain a judgment conferring on

<PAGE>

the Mortgagee the right to immediate possession and requiring the Owner to
execute and deliver such instruments and documents to the Mortgagee, to the
entry of which judgment the Owner hereby specifically consents to the fullest
extent permitted by Law, and (ii) pursue all or part of such Collateral wherever
it may be found and may enter any of the premises of Owner wherever such
Collateral may be or be supposed to be and search for such Collateral and take
possession of and remove such Collateral. 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 Mortgagee may,
from time to time, at the expense of the Collateral, make all such expenditures
for maintenance, use, operation, storage, insurance, leasing, control,
management, disposition, modifications or alterations to and of the Collateral,
as it may deem proper. In each such case, the Mortgagee shall have the right to
maintain, use, operate, store, insure, lease, control, manage, dispose of,
modify or alter the Collateral and to exercise all rights and powers of the
Owner relating to the Collateral, as the Mortgagee 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 Collateral or any part thereof as
the Mortgagee may determine, and the Mortgagee shall be entitled to collect and
receive directly all rents, revenues and other proceeds of the Collateral and
every part thereof, without prejudice, however, to the right of the Mortgagee
under any provision of this Trust Indenture to collect and receive all cash held
by, or required to be deposited with, the Mortgagee hereunder. Such rents,
revenues and other proceeds shall be applied to pay the expenses of the
maintenance, use, operation, storage, insurance, leasing, control, management,
disposition, improvement, modification or alteration of the Collateral and of
conducting the business thereof, and to make all payments which the Mortgagee
may be required or may elect to make, if any, for taxes, assessments, insurance
or other proper charges upon the Collateral 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), and all other payments
which the Mortgagee 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 Mortgagee, and of all persons properly engaged and employed by
the Mortgagee with respect hereto.

            SECTION 5.04. REMEDIES CUMULATIVE

            Each and every right, power and remedy given to the Mortgagee
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 Mortgagee, 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 Mortgagee 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 or to be an acquiescence therein.

<PAGE>

            SECTION 5.05. DISCONTINUANCE OF PROCEEDINGS

            In case the Mortgagee 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
Mortgagee, then and in every such case the Owner and the Mortgagee shall,
subject to any determination in such proceedings, be restored to their former
positions and rights hereunder with respect to the Collateral, and all rights,
remedies and powers of the Owner or the Mortgagee shall continue as if no such
proceedings had been instituted.

            SECTION 5.06. WAIVER OF PAST DEFAULTS

            Upon written instruction from a Majority in Interest of Note
Holders, the Mortgagee 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
Mortgagee shall not waive any Default (i) in the payment of the Original 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 hereof, cannot be modified or amended without the
consent of each Note Holder.

             SECTION 5.07.  APPOINTMENT OF RECEIVER

            The Mortgagee shall, as a matter of right, be entitled to the
appointment of a receiver (who may be the Mortgagee or any successor or nominee
thereof) for all or any part of the Collateral, whether such receivership be
incidental to a proposed sale of the Collateral or the taking of possession
thereof or otherwise, and the 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 Collateral shall be entitled to exercise all the rights
and powers of the Mortgagee with respect to the Collateral.

            SECTION 5.08. MORTGAGEE AUTHORIZED TO EXECUTE BILLS OF SALE, ETC.

            The Owner irrevocably appoints, while an Event of Default has
occurred and is continuing, the Mortgagee the true and lawful attorney-in-fact
of the Owner (which appointment is coupled with an interest) in its name and
stead and on its behalf, for the purpose of effectuating 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 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 Mortgagee or any purchaser, the Owner shall
ratify and confirm any such sale, assignment, transfer or delivery, by executing
and delivering to the Mortgagee 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.

<PAGE>

            SECTION 5.09. 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 premium, 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 VI

                             DUTIES OF THE MORTGAGEE

            SECTION 6.01. NOTICE OF EVENT OF DEFAULT

            If the Mortgagee shall have Actual Knowledge of an Event of Default
or of a Default arising from a failure to pay any installment of principal and
interest on any Equipment Note, the Mortgagee shall give prompt written notice
thereof to each Note Holder. Subject to the terms of Sections 5.06, 6.02 and
6.03 hereof, the Mortgagee 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 Mortgagee shall be
instructed in writing by a Majority in Interest of Note Holders. Subject to the
provisions of Section 6.03, if the Mortgagee shall not have received
instructions as above provided within 20 days after mailing notice of such Event
of Default to the Note Holders, the Mortgagee may, subject to instructions
thereafter received pursuant to the preceding provisions of this Section 6.01,
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; PROVIDED, HOWEVER, that the Mortgagee may not sell the Aircraft or any
Engine without the consent of a Majority in Interest of Note Holders. For all
purposes of this Trust Indenture, in the absence of Actual Knowledge on the part
of the Mortgagee, the Mortgagee shall not be deemed to have knowledge of a
Default or an Event of Default (except, the failure of Owner to pay any
installment of principal or interest within one Business Day after the same
shall become due, which failure shall constitute knowledge of a Default) unless
notified in writing by the Owner or one or more Note Holders.

            SECTION 6.02. ACTION UPON INSTRUCTIONS; CERTAIN RIGHTS AND
LIMITATIONS

            Subject to the terms of Sections 5.02(a), 5.06, 6.01 and 6.03
hereof, upon the written instructions at any time and from time to time of a
Majority in Interest of Note Holders, the Mortgagee shall, subject to the terms
of this Section 6.02, 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 hereunder
with respect to any part of the Collateral as shall be specified in such
instructions; it being understood that without the written instructions of a
Majority in Interest of Note Holders, the Mortgagee shall not, except as
provided in Section 6.01, approve any such matter as satisfactory to the
Mortgagee.

<PAGE>

                  The Mortgagee will execute and the Owner will file such
continuation statements with respect to financing statements relating to the
security interest created hereunder in the Collateral as may be specified from
time to time in written instructions of a Majority in Interest of Note Holders
(which instructions shall be accompanied by the form of such continuation
statement so to be filed). The Mortgagee 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 Mortgagee
hereunder.

            SECTION 6.03. INDEMNIFICATION

            The Mortgagee shall not be required to take any action or refrain
from taking any action under Section 6.01 (other than the first sentence
thereof), 6.02 or Article V hereof unless the Mortgagee 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 Mortgagee
agrees that it shall look solely to the Note Holders for the satisfaction of any
indemnity (except expenses for foreclosure of the type referred to in clause
"First" of Section 3.03 hereof) owed to it pursuant to this Section 6.03. The
Mortgagee shall not be under any obligation to take any action under this Trust
Indenture or any other Operative Agreement and nothing herein or therein shall
require the Mortgagee 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 the Mortgagee shall be accepted as reasonable assurance of
adequate indemnity). The Mortgagee shall not be required to take any action
under Section 6.01 (other than the first sentence thereof) or 6.02 or Article V
hereof, nor shall any other provision of this Trust Indenture or any other
Operative Agreement be deemed to impose a duty on the Mortgagee to take any
action, if the Mortgagee shall have been advised by counsel that such action is
contrary to the terms hereof or is otherwise contrary to Law.

            SECTION 6.04. NO DUTIES EXCEPT AS SPECIFIED IN TRUST INDENTURE OR
INSTRUCTIONS

            The Mortgagee 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 Collateral, or to otherwise take or refrain
from taking any action under, or in connection with, this Trust Indenture or any
part of the Collateral, 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 Mortgagee. The Mortgagee 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
hereof), promptly take such action as may be necessary duly to discharge all
liens and encumbrances on any part of the Collateral which result from claims
against it in its individual capacity not related to the administration of the
Collateral or any other transaction pursuant to this Trust Indenture or any
document included in the Collateral.

<PAGE>

            SECTION 6.05. NO ACTION EXCEPT UNDER TRUST INDENTURE OR INSTRUCTIONS

            The Mortgagee will not use, operate, store, lease, control, manage,
sell, dispose of or otherwise deal with the Aircraft or any other part of the
Collateral except in accordance with the powers granted to, or the authority
conferred upon the Mortgagee pursuant to this Trust Indenture and in accordance
with the express terms hereof.

            SECTION 6.06. INVESTMENT OF AMOUNTS HELD BY MORTGAGEE

            Any amounts held by the Mortgagee 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 Agreement providing for amounts to be held by
the Mortgagee which are not distributed pursuant to the other provisions of
Article III hereof shall be invested by the Mortgagee from time to time in Cash
Equivalents as directed by the Owner so long as the Mortgagee may acquire the
same using its best efforts. All Cash Equivalents held by the Mortgagee pursuant
to this Section 6.06 shall either be (a) registered in the name of, payable to
the order of, or specially endorsed to, the Mortgagee, or (b) held in an
Eligible Account. Unless otherwise expressly provided in this Trust Indenture,
any income realized as a result of any such investment, net of the Mortgagee's
reasonable fees and expenses in making such investment, shall be held and
applied by the Mortgagee 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
Mortgagee 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 Mortgagee without instructions whenever
such sale is necessary to make a distribution required by this Trust Indenture.

                                  THE MORTGAGEE

            SECTION 7.01. ACCEPTANCE OF TRUSTS AND DUTIES

            The Mortgagee 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
Collateral in accordance with the terms hereof. The Mortgagee, in its individual
capacity, shall not be answerable or accountable under any circumstances, except
(i) for its 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) as provided in the fourth sentence of Section
2.04(a) hereof and the last sentence of Section 6.04 hereof, and (iii) from the
inaccuracy of any representation or warranty of the Mortgagee (in its individual
capacity) in the Participation Agreement or expressly made hereunder.

<PAGE>

            SECTION 7.02. ABSENCE OF DUTIES

            Except in accordance with written instructions furnished pursuant to
Section 6.01 or 6.02 hereof, and except as provided in, and without limiting the
generality of, Sections 6.03, 6.04 and 7.07 hereof the Mortgagee shall have no
duty (i) to see to any registration of the Aircraft or any recording or filing
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 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 Collateral, (iv) to
confirm, verify or inquire into the failure to receive any financial statements
from Owner, or (v) to inspect the Aircraft at any time or ascertain or inquire
as to the performance or observance of any of Owner's covenants herein or any
Permitted Lessee's covenants under any assigned Permitted Lease with respect to
the Aircraft.

            SECTION 7.03. NO REPRESENTATIONS OR WARRANTIES AS TO AIRCRAFT OR
DOCUMENTS

            THE MORTGAGEE 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 Mortgagee, in its
individual or trust capacities, does not make or shall not be deemed to have
made any representation or warranty as to the validity, legality or
enforceability of this Trust Indenture, the Participation Agreement, the
Equipment Notes, or the Purchase Agreement, or as to the correctness of any
statement contained in any thereof, except for the representations and
warranties of the Owner made in its individual capacity and the representations
and warranties of the Mortgagee in its individual capacity, in each case
expressly made in this Trust Indenture or in the Participation Agreement. The
Note Holders make no representation or warranty hereunder whatsoever.

            SECTION 7.04. NO SEGREGATION OF MONIES; NO INTEREST

            Any monies paid to or retained by the Mortgagee pursuant to any
provision hereof and not then required to be distributed to the Note Holders, or
the Owner as provided in Article III hereof need not be segregated in any manner
except to the extent required by Law or Section 6.06 hereof, and may be
deposited under such general conditions as may be prescribed by Law, and the
Mortgagee shall not be liable for any interest thereon (except that the
Mortgagee 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 Mortgagee

<PAGE>

shall be accounted for by the Mortgagee so that any portion thereof paid or
applied pursuant hereto shall be identifiable as to the source thereof.

            SECTION 7.05. RELIANCE; AGREEMENTS; ADVICE OF COUNSEL

            The Mortgagee 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
Mortgagee may accept a copy of a resolution of the Board of Directors (or
Executive Committee thereof) of the Owner, 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 Original Amount of
Equipment Notes outstanding as of any date, the Owner may for all purposes
hereof rely on a certificate signed by any Vice President or other authorized
corporate trust officer of the Mortgagee. As to any fact or matter relating to
the Owner the manner of the ascertainment of which is not specifically described
herein, the Mortgagee may for all purposes hereof rely on a certificate, signed
by a duly authorized officer of the Owner, as to such fact or matter, and such
certificate shall constitute full protection to the Mortgagee 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 Mortgagee 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 Collateral, advise
with counsel, accountants and other skilled persons to be selected and retained
by it, and the Mortgagee shall not be liable for anything done, suffered or
omitted in good faith by it in accordance with the written advice or written
opinion of any such counsel, accountants or other skilled persons.

            SECTION 7.06. COMPENSATION

            The Mortgagee 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 Collateral 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
Collateral toward such payments. The Mortgagee agrees that it shall have no
right against the Note Holders for any fee as compensation for its services as
trustee under this Trust Indenture.

            SECTION 7.07. INSTRUCTIONS FROM NOTE HOLDERS

            In the administration of the trusts created hereunder, the Mortgagee
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 Mortgagee's duties or obligations hereunder
be unclear, and the Mortgagee shall incur no liability in refraining from acting
until it receives such instructions. The Mortgagee shall be fully protected for
acting in accordance with any instructions received under this Section 7.07.

                  SECTION 8.01.  SCOPE OF INDEMNIFICATION

            The Mortgagee shall be indemnified by the Owner to the extent and in

                                   ARTICLE IX

                         SUCCESSOR AND SEPARATE TRUSTEES

            SECTION 9.01. RESIGNATION OF MORTGAGEE; APPOINTMENT OF SUCCESSOR

                  (a) The Mortgagee or any successor thereto may resign at any
time without cause by giving at least 30 days' prior written notice to the Owner
and each Note Holder, such resignation to be effective upon the acceptance of
the trusteeship by a successor Mortgagee. 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 is continuing) remove the Mortgagee without
cause by an instrument in writing delivered to the Owner and the Mortgagee, and
the Mortgagee shall promptly notify each Note Holder thereof in writing, such
removal to be effective upon the acceptance of the trusteeship by a successor
Mortgagee. In the case of the resignation or removal of the Mortgagee, a
Majority in Interest of Note Holders may appoint a successor Mortgagee 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 Mortgagee shall not have been appointed
within 30 days after such notice of resignation or removal, the Mortgagee, the
Owner or any Note Holder may apply to any court of competent jurisdiction to
appoint a successor Mortgagee to act until such time, if any, as a successor
shall have been appointed as above provided. The successor Mortgagee so
appointed by such court shall immediately and without further act be superseded
by any successor Mortgagee appointed as above provided.

                  (b) Any successor Mortgagee, however appointed, shall execute
and deliver to the Owner and the predecessor Mortgagee an instrument accepting
such appointment and assuming the obligations of the Mortgagee arising from and
after the time of such appointment, and thereupon such successor Mortgagee,
without further act, shall become vested with all the estates, properties,
rights, powers and duties of the predecessor Mortgagee hereunder in the trust
hereunder applicable to it with like effect as if originally named the Mortgagee
herein; but nevertheless upon the written request of such successor Mortgagee,
such predecessor Mortgagee shall execute and deliver an instrument transferring
to such successor Mortgagee, upon the trusts herein expressed applicable to it,
all the estates, properties, rights and powers of such predecessor Mortgagee,
and such predecessor Mortgagee shall duly assign, transfer, deliver and pay over
to such successor Mortgagee all monies or other property then held by such
predecessor Mortgagee hereunder.

<PAGE>

                  (c) Any successor Mortgagee, however appointed, shall be a
bank or trust company having its principal place of business in the Borough of
Manhattan, City and State of New York; Chicago, Illinois; Hartford, Connecticut;
Wilmington, Delaware; or Boston, Massachusetts and having (or whose obligations
under the Operative Agreements 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
Mortgagee hereunder upon reasonable or customary terms.

                  (d) Any corporation into which the Mortgagee 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 Mortgagee shall be a
party, or any corporation to which substantially all the corporate trust
business of the Mortgagee may be transferred, shall, subject to the terms of
paragraph (c) of this Section 9.01, be a successor Mortgagee and the Mortgagee
under this Trust Indenture without further act.

            SECTION 9.02. APPOINTMENT OF ADDITIONAL AND SEPARATE TRUSTEES

                  (a) Whenever (i) the Mortgagee shall deem it necessary or
desirable in order to conform to any Law of any jurisdiction in which all or any
part of the Collateral shall be situated or to make any claim or bring any suit
with respect to or in connection with the Collateral, this Trust Indenture, any
other Indenture Agreement, the Equipment Notes or any of the transactions
contemplated by the Participation Agreement, (ii) the Mortgagee shall be advised
by counsel satisfactory to it that it is so necessary or prudent in the
interests of the Note Holders (and the Mortgagee shall so advise the Owner), or
(iii) the Mortgagee shall have been requested to do so by a Majority in Interest
of Note Holders, then in any such case, the Mortgagee and, upon the written
request of the Mortgagee, the 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 Mortgagee, either to act
jointly with the Mortgagee as additional trustee or trustees of all or any part
of the Collateral, or to act as separate trustee or trustees of all or any part
of the Collateral, 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 Mortgagee 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 or separate trustee, subject in each case to the remaining
provisions of this Section 9.02. If the Owner shall not have taken any action
requested of it under this Section 9.02(a) that is permitted or required by its
terms within 15 days after the receipt of a written request from the Mortgagee
so to do, or if an Event of Default shall have occurred and be continuing, the
Mortgagee may act under the foregoing provisions of this Section 9.02(a) without
the concurrence of the Owner, and the Owner hereby irrevocably appoints (which
appointment is coupled with an interest) the Mortgagee, its agent and
attorney-in-fact to act for it under the foregoing provisions of this Section
9.02(a) in either of such contingencies. The Mortgagee 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 9.02(a) shall die, become incapable of acting,

<PAGE>

resign or be moved, all the assets, property, rights, powers, trusts, duties and
obligations of such additional or separate trustee shall revert to the Mortgagee
until a successor additional or separate trustee is appointed as provided in
this Section 9.02(a).

                  (b) No additional or separate trustee shall be entitled to
exercise any of the rights, powers, duties and obligations conferred upon the
Mortgagee 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 Collateral or otherwise payable under any Operative Agreement to the
Mortgagee shall be promptly paid over by it to the Mortgagee. All other rights,
powers, duties and obligations conferred or imposed upon any additional or
separate trustee shall be exercised or performed by the Mortgagee 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
Mortgagee 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 Collateral 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
Mortgagee 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 Mortgagee shall be liable for the consequences of its
lack of reasonable care in selecting, and the Mortgagee's own actions in acting
with, any additional or separate trustee. Each additional or separate trustee
appointed pursuant to this Section 9.02 shall be subject to, and shall have the
benefit of Articles V through IX and Article XI hereof insofar as they apply to
the Mortgagee. The powers of any additional or separate trustee appointed
pursuant to this Section 9.02 shall not in any case exceed those of the
Mortgagee hereunder.

                  (c) If at any time the Mortgagee shall deem it no longer
necessary or 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 Mortgagee shall
have been requested to do so in writing by a Majority in Interest of Note
Holders, the Mortgagee and, upon the written request of the Mortgagee, the
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 Mortgagee may act on behalf of the Owner under this
Section 9.02(c) when and to the extent it could so act under Section 9.02(a)
hereof.
