and all accrued and unpaid interest on, and any other amounts due under, this
Equipment Note. Notwithstanding anything to the contrary contained herein,
whenever the date scheduled for any payment to be made hereunder or under the

SECTION 2.02. ISSUANCE AND TERMS OF EQUIPMENT NOTES

         The Equipment Notes shall be dated the date of issuance thereof, shall
be issued in two separate series consisting of Series A and Series B and in the
maturities and principal amounts and shall bear interest as specified in
Schedule I hereto. On the date thereof, each Equipment Note shall be issued to
the Subordination Agent on behalf of the Pass Through Trustee under the Pass
Through Trust Agreements. 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 for the
applicable Series of such Equipment Note (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 _____ __, ____, and
on each [January 15], [April 15], [July 15] and [October 15] thereafter until
maturity. The Original Amount of each Equipment Note 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 the Equipment Notes. Notwithstanding the foregoing, the final
payment made under each Equipment Note shall be in an amount sufficient to
discharge in full the unpaid 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 Past 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, whenever the date scheduled for any payment to be
made hereunder or under any Equipment Note shall not be a Business Day, then
such payment shall not be due on such scheduled date but shall be due on the
next succeeding Business Day with the same effect as if paid on the originally
scheduled due date. The interest rate borne by the Equipment Notes shall be
subject to adjustments to the extent, and under the circumstances, specified by
the Registration Rights Agreement.


         The Owner agrees, without duplication, to pay to the Mortgagee for
distribution in accordance with Section 3.04 hereof (1) all Expenses,
Transaction Expenses, and all other amounts, liabilities, indemnities, and
obligations (including any Make-Whole Amount) that Owner assumes or

                                       11

becomes obligated to pay or agrees to pay under any Operative Agreement to or on
behalf of Mortgagee or any other Person including indemnity payments under
Section 7 of the Participation Agreement, but excluding any amount as to which
Owner is obligated to pay a pro rata share pursuant to clause (5) of this
definition, (2)(a) to the extent not payable (whether or not in fact paid) under
Section 6(a) or Section 6(b), as applicable, of the Note Purchase Agreement (as
originally in effect or amended with Mortgagee's consent), the fees payable to
Liquidity Provider under Section 2.3 of each Liquidity Facility, multiplied by a
fraction the numerator of which is the then-outstanding aggregate principal
amount of all the series of Equipment Notes, and the denominator of which is the
then-outstanding aggregate principal amount of all "Series A Equipment Notes"
and "Series B Equipment Notes" (each as defined in the Note Purchase Agreement);
(b) (x) the amount equal to interest on any Downgrade Advance (other than any
Applied Downgrade Advance) payable under Section 3.7 of each Liquidity Facility
minus Investment Earnings from such Downgrade Advance, multiplied by (y) the
fraction specified in the foregoing clause (a); (c) (x) the amount equal to
interest on any Non-Extension Advance (other than any Applied Non-Extension
Advance) payable under Section 3.7 of each Liquidity Facility, multiplied by (y)
the fraction specified in the forgoing clause (a); (d) if any payment default
exists with respect to interest on any series of Equipment Notes, (x) an amount
equal to interest on any Unpaid Advance, Applied Downgrade Advance, or Applied
Non-Extension Advance payable under Section 3.7 of each Liquidity Facility plus
any interest at the Past-Due Rate actually payable (whether or not in fact paid)
by Owner in respect of the overdue scheduled interest on the Equipment Notes in
respect of which such Unpaid Advance, Applied Downgrade Advance, or Applied
Non-Extension Advance was made by the applicable Liquidity Provider multiplied
by (y) a fraction the numerator of which is the sum of all then-overdue interest
on the Equipment Notes (other than interest becoming due and payable solely as a
result of acceleration of any Equipment Notes), and the denominator of which
shall be the sum of all then-overdue interest on all "Series A Equipment Notes"
and "Series B 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 (e) Owner's pro rata share of any other
amounts owed to Liquidity Provider by 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 (a), (b), (c), or (d) above, (3) Owner's pro rata share of all
compensation and reimbursement of expenses, disbursements, and advances payable
by Owner under the Pass-Through Trust Agreements, (4) Owner's pro rata share of
all compensation and reimbursement of expenses and disbursements (including
payments of indemnities) payable to Subordination Agent under the Intercreditor
Agreement, except with respect to

                                       12

2002 EETC - Mortgage (Owned) (10)

<PAGE>

any income or franchise taxes incurred by Subordination Agent in connection with
the transactions contemplated by the Intercreditor Agreement, (5) Owner's pro
rata share of any amount payable under Section 7.1 (and, if attributable
thereto, Section 7.5) of the Participation Agreement to any Pass-Through
Indemnitee to the extent such amount relates to, results from, or arises out of
or in connection with (a) the Pass-Through Agreements or the enforcement of any
of the terms of any of the Pass-Through Agreements, (b) the offer, sale, or
delivery of the Pass-Through Certificates or any interest therein or represented
thereby, or (c) any breach of or failure to perform or observe, or any other
noncompliance with, any covenant or agreement or other obligation to be
performed by Owner under any Pass-Through Agreement, or the falsity of any
representation or warranty of Owner in any Pass-Through Agreement, and (6) if
Owner requests any amendment to any Operative Agreement or Pass-Through
Agreement, Owner's pro rata share of all reasonable fees and expenses (including
fees and disbursements of counsel) of Escrow Agents and Paying Agents in
connection therewith payable by 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 then-outstanding principal balance of
Equipment Notes, and the denominator of which is the aggregate then-outstanding
principal balance of all "Equipment Notes" (as each such term is defined in each
of the Operative Indentures). For purposes of this definition, "Applied
Downgrade Advance", "Applied Non-Extension Advance", "Cash Collateral Account",
"Downgrade Advance", "Final Advance", "Investment Earnings", "Non-Extension
Advance", and "Unpaid Advance" have the same meanings as in each Liquidity
Facility.

         The Equipment Notes shall be executed on behalf of the Owner by its
President or one of its Vice Presidents, Assistant Vice Presidents or Assistant
Secretaries or other authorized officer. Equipment Notes bearing the signatures
of individuals who were at any time the proper officers of 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 a Vice President or
Assistant Vice President or other authorized officer of the Owner; provided,
however, that each such request shall specify the aggregate Original Amount of
all Equipment Notes to be authenticated hereunder on original issue with respect
to the Aircraft. No Equipment Note shall be secured by or entitled to any
benefit under this Trust Indenture or be valid or obligatory for any purposes,
unless there appears on such Equipment Note a certificate of authentication in
the form provided for

                                       13

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 ____________________.


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 11:00
a.m., New York City 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

                                       14

2002 EETC - Mortgage (Owned) (10)

<PAGE>

such funds were received after 12:00 noon, New York City 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 such withholding shall constitute payment in respect
of such Equipment Note) and timely pay the same to the appropriate authority in
the name of and on behalf of the Note Holders, that it will file any necessary
United States withholding tax returns or statements when due, and that as
promptly as possible after the payment thereof it will deliver to each Note
Holder (with a copy to the Owner) 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 W-8BEN (or such successor form or forms as may be required
by the United States Treasury Department) during the calendar year in which the
payment hereunder or under the Equipment Note(s) held by such holder is made
(but prior to the making of such payment), or in either of the two preceding
calendar years, and has not notified the 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,

                                       15

2002 EETC - Mortgage (Owned) (10)

<PAGE>

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 (and such withholding shall constitute payment in respect of such Equipment
Note). If a Note Holder (x) which is a Non-U.S. Person has furnished to the
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
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

                                       16

    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 normal maturity.


SECTION 2.06. TERMINATION OF INTEREST IN COLLATERAL

         No Note Holder or any other Mortgage 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 Mortgage Indemnitee 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

<PAGE>

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 and of the same Series, 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 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 Indenture and the Participation Agreement applicable to Note Holders,
including Sections 5.3, 5.4

and 8.1 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 ten 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 of the same Series 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 and the Mortgagee 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 ten
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.


SECTION 2.10.  MANDATORY REDEMPTIONS OF EQUIPMENT NOTES

         On the date on which the Owner is required pursuant to Section 4.05
hereof to make payment for an Event of Loss with respect to the Airframe, all of
the Equipment Notes shall be redeemed in whole at a redemption price equal to
100% of the unpaid Original Amount thereof, together with all accrued interest
thereon to the date of redemption and all other Secured Obligations owed or then
due and payable to the Note Holders but without Make-Whole Amount.


SECTION 2.11.  VOLUNTARY REDEMPTIONS OF EQUIPMENT NOTES

         All (but not less than all) of the Equipment Notes may be redeemed by
the Owner upon at least 30 days' revocable prior written notice to the Mortgagee
and the Note Holders, and the Equipment Notes shall be redeemed in whole at a
redemption price equal to 100% of the unpaid Original Amount thereof, together
with accrued interest thereon to the date of redemption and all other Secured
Obligations owed or then due and payable to the Note Holders plus Make-Whole
Amount, if any. Simultaneously with such redemption, the Owner shall also pay
all other Secured Obligations (if any) owed to the Mortgagee and the Mortgage
Indemnitee.


SECTION 2.12.  REDEMPTIONS; NOTICE OF REDEMPTION

         (a) No redemption of any Equipment Note may be made except to the
extent and in the manner expressly permitted by this Trust Indenture. No
purchase of any Equipment Note may be made by the Mortgagee.

         (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 25 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
cease to accrue on and after such redemption

surrendered for payment of the redemption 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 p.m. New York City time on the redemption date in immediately
available funds the redemption price of the Equipment Notes to be redeemed.

         (d) Notice of redemption having been given and not revoked as
aforesaid, the Equipment Notes to be redeemed shall, on the redemption date,
become due and payable at the Corporate Trust Office of the Mortgagee or at any
office or agency maintained for such purposes pursuant to Section 2.07, and from
and after such redemption date (unless there shall be a default in the payment
of the redemption price) any such Equipment Notes then outstanding shall cease
to bear interest. Upon surrender of any such Equipment Note for redemption 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.


SECTION 2.13. SUBORDINATION

         (a) The Owner and, by acceptance of its Equipment Notes of any Series,
each Note Holder of such Series, hereby agree that no payment or distribution

Holder of such Series, including any payment or distribution of cash, property
or securities after the commencement of a proceeding of the type referred to in
Section 5.01(vi) hereof, except as expressly provided in Article III hereof.

         (b) By the acceptance of its Equipment Notes of any Series (other than

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 Article III hereof.

held by the Mortgagee as permitted by Section 7.04 hereof (provided that such
moneys shall be invested as provided in Section 6.06 hereof) as additional
security for the obligations of Owner under Operative Agreements and such
proceeds (and such investment earnings), to the extent not theretofore applied
as provided herein, shall be released to the Owner at the Owner's written
request upon the release of such Airframe or Engine and the replacement thereof
as provided herein; provided, further, that no Make-Whole Amount shall be

              liquidated or otherwise, upon such Event of Default shall be
              applied by the Mortgagee as between itself, WTC and the Note
              Holders in reimbursement of such expenses and any other expenses
              for which the Mortgagee, WTC or the Note Holders are entitled to

              other, in proportion to the amounts owed each hereunder;

Second,       so much of such payments or amounts remaining as shall be required
              to reimburse the then existing or prior Note Holders for payments
              made pursuant to Section 6.03 hereof (to the extent not previously
              reimbursed) shall be distributed to such then existing or prior
              Note Holders ratably, without priority of one over the other, in
              accordance with the amount of the payment or payments made by each

              Make-Whole Amount) to the date of distribution, shall be
              distributed to the Note Holders of Series A, and in case the
              aggregate amount so to be distributed shall be insufficient to
              pay in full as aforesaid, then ratably, without priority of one
              over the other, in the proportion that the aggregate unpaid
              Original Amount of all Series A Equipment Notes held by each
              holder plus the accrued but unpaid interest and other amounts due
              hereunder or thereunder (other than Make-Whole Amount, if any) to

              thereon (other than Make-Whole Amount which shall not be due and
              payable) and all other Secured Obligations in respect of the
              Series B Equipment Notes (other than Make-Whole Amount) to the
              date of distribution, shall be distributed to the Note Holders of
              Series B, and in case the aggregate amount so to be distributed
              shall be insufficient to pay in full as aforesaid, then ratably,
              without priority of one over the other, in the proportion that the
              aggregate unpaid Original Amount of all Series B Equipment Notes
              held by each holder plus the accrued but unpaid interest and other
              amounts due hereunder or thereunder (other than the Make-Whole
              Amount, if any) to the date of distribution, bears to the
              aggregate unpaid Original Amount of all Series B Equipment Notes
              held by all such holders plus the accrued but unpaid interest and
              other amounts due thereon (other than the Make-Whole Amount) to
              the date of distribution; and

Fourth,       the balance, if any, of such payments or amounts remaining
              thereafter shall be distributed to the Owner.

an Event of Default.

    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

    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 with any Permitted Air Carrier that is not the subject to any

    proceeding and shall not have substantially all of its property in the
    possession of any liquidator, trustee, receiver or similar person; provided
    that, in the case only of a lease to a Permitted Foreign Air Carrier, (A)
    the United States maintains diplomatic relations with the country of
    domicile of such Permitted Foreign Air 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 (subject to customary exceptions), (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,

    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 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 (subject to customary exceptions);

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

affect the United States registration of the Aircraft, unless the Aircraft is
subject to reregistration in accordance with the provisions of Section 4.02(d)
or the maintenance, operation or use thereof except in compliance with Sections
4.02(c) and 4.04(a) 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

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
accordance with the limitations applicable to the Owner's possession and use
provided in this Trust Indenture and provisions for the maintenance and
inspection of the Aircraft that are the same in all material respects as are
contained herein. No lease permitted under this Section 4.02(b) shall be entered
into unless (w) Owner shall provide written notice to Mortgagee and Moody's
(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, at least 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

out-of-pocket fees and expenses, including, without limitation, reasonable fees
and disbursements of counsel, incurred by Mortgagee in connection with any such
lease, and any such lease for a term of more than a year shall be assigned to
Mortgagee to secure Owner's obligations hereunder. 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
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 covering such area in accordance with Section 4.06(c), or (ii) in any
recognized area of hostilities unless covered in accordance with Annex B by War
Risk Insurance as required by the terms of Section 4.06 (including, without
limitation, Section 4.06(c)), unless in any case referred to in this Section
4.02(c) 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 or materially and adversely affect the interest
of any Note Holder therein, any material risk of criminal liability 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, Japan, or the Joint Aviation Authority (being the central
aviation authority of France, Germany, Japan, the Netherlands, and the United
Kingdom, inter alia) for the Aircraft, Airframe and Engines (the "Maintenance
Program"), 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

                                       31

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,
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 with the FAA 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 5.4.5 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).

<PAGE>

         (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 4.02(e).


SECTION 4.03. INSPECTION

         (a) At all reasonable times and upon reasonable advance notice (taking
into consideration the availability of the Aircraft and Owner (or Permitted
Lessee) personnel), 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 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 Trust 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

                                       33

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 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

                                       34

2002 EETC - Mortgage (Owned) (10)

<PAGE>

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


                                       35

2002 EETC - Mortgage (Owned) (10)

<PAGE>

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
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 five 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 applicable conditions precedent set forth in Section
4.05(c) at the Owner's sole

                                       36

2002 EETC - Mortgage (Owned) (10)

<PAGE>

cost and expense, and the Mortgagee agrees to cooperate with the Owner to the
extent necessary to enable it to timely satisfy such conditions.


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)):

                  (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 with respect to an Airframe or within
         60 days of such Event of Loss with respect to any Engine, 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 (or if directed by the Owner, the insurers having made
payment in respect of the applicable Event of Loss) 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 Sections 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 4.04(e) or 4.05(a)(i), as the case may be, shall be subject
to the fulfillment, at the Owner's sole cost and expense, in addition to the
conditions contained in such Section 4.04(e) or 4.05(a)(i), as the case may be,
of the following conditions precedent:

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

                  accordance with Section 4.02(d), as the case may be;

                  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

         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;

         than Permitted Liens), (B) the Replacement Airframe shall have
         been duly certified by the FAA or other applicable Aviation Authority
         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 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 (1) 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 (2) the FAA Bills of Sale constitutes an effective
         instrument for the conveyance of title to the Replacement Airframe or

         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).

         Owner and Mortgagee understand and agree that if, at the time of any
replacement of the Airframe or any Engine(s) as contemplated in this Section
4.05, the Airframe was registered in a jurisdiction other than the United
States, then the requirements set forth above in this Section 4.05 relating to
compliance with the requirements of the Transportation Code or the

FAA shall be deemed to refer to the comparable applicable Law of, and the
Aviation Authority of, such other jurisdiction.

                  (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:

                           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. 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 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)

                                       41

<PAGE>

to the same extent as if an Event of Loss in respect of such Engine had occurred
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
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 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.

                  (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.

<PAGE>

                  (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 or any Permitted Lessee) 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 (or
as Owner shall direct).


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) if the Aircraft is, at the time, registered with the
         FAA, such person makes such filings and recordings with the FAA
         pursuant to the Act as shall be necessary to evidence such
         consolidation or merger or, if the Aircraft is, at the time, not
         registered with the FAA, such person makes such filings and recordings
         with the Aviation Authority as shall be necessary to evidence such
         consolidation or merger; and

                  (iv) Owner furnishes Mortgagee an opinion of counsel
         reasonably satisfactory to Mortgagee to the effect that such
         consolidation or merger

         has satisfied at the closing of such consolidation or merger items (i),
         (ii) and (iii) above; and


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

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

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

                                       46

<PAGE>

unpaid interest (without Make-Whole Amount) 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
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

                                       48

2002 EETC - Mortgage (Owned) (10)

<PAGE>

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.

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

                                       49

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, effective during the continuance of any Event
of Default, 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.

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.

                             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.

2002 EETC - Mortgage (Owned) (10)

<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 (or a Note Holder who
has all of its obligations guaranteed by 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

                                       52

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 ownership of the
Aircraft or the administration of the Collateral or any other transaction
pursuant to this Trust Indenture or any document included in the Collateral.

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 or negligence in the handling of funds,
and any such investment may be sold (without regard to its

to make a distribution required by this Trust Indenture.

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 Trust
Indenture Estate 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.


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

EXPRESS OR IMPLIED, AS TO THE TITLE, AIRWORTHINESS, VALUE, COMPLIANCE WITH
SPECIFICATIONS, CONDITION, DESIGN, QUALITY, DURABILITY, OPERATION,

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 the Guarantee, 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

         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 or Default has occurred and is continuing (or in the absence of such
direction, by the Majority In Interest of Note Holders) in Cash Equivalents
either registered in the name of the Mortgagee or credited to an Eligible
Account of the type described in clause (a) of the definition thereof; provided,
however, that any payments received, or applied hereunder, by the Mortgagee
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 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

opinion of any such counsel, accountants or other skilled persons.


SECTION 7.06. COMPENSATION

         (a) The Mortgagee shall be entitled to reasonable compensation 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 (and for expenses and disbursements, including the reasonable fees
and expenses of counsel), 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.

         (b) The Owner agrees to indemnify the Mortgagee against any taxes
imposed upon it relating to, or arising out of the performance of its
responsibilities hereunder other than taxes, fees or charges based on, or

rendered in connection with the Transaction.


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

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.

         (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 Salt Lake City, Utah; 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

                                       58

<PAGE>

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,
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.

Permitted Liens or deprive any Note Holder of the benefit of the Lien of this
Trust Indenture on the Collateral, except as provided in connection with the

         (b) The Owner and the Mortgagee may enter into one or more agreements
supplemental hereto without the consent of any Note Holder for any of the
following purposes: (i) (a) to cure any defect or inconsistency herein or in the
Equipment Notes, or to make any change not inconsistent with the provisions
hereof (provided that such change does not adversely affect the interests of any
Note Holder in its capacity solely as Note Holder) or (b) to cure any ambiguity
or correct any mistake; (ii) to evidence the succession of another party as the
Owner in accordance with the terms hereof or to evidence the succession of a new
trustee hereunder pursuant hereto, the removal of the trustee hereunder or the

         Capitalized terms used but not defined herein shall have the respective
meanings set forth or incorporated by reference in Annex A to the Trust
Indenture.


A. LIABILITY INSURANCE

         1. Except as provided in Section A.2 below, Owner will carry or cause
to be carried at all times, at no expense to Mortgagee, comprehensive airline
legal liability (including, but not limited to passenger liability, property
damage, and contractual liability insurance) with respect to the Aircraft, the

(x) the amount of comprehensive airline legal liability insurance from time to
time applicable to aircraft owned or leased and operated by Owner of the same
type and operating on similar routes as the Aircraft and (y) the Minimum
Liability Insurance Amount per occurrence;(ii) of the type and covering the same
risks as from time to time applicable to aircraft operated by Owner of the same
type as the Aircraft; and (iii) maintained in effect with insurers of nationally
or internationally recognized responsibility (such insurers being referred to
herein as "Approved Insurers").

         2. During any period that the Aircraft is on the ground and not in
operation, Owner may carry or cause to be carried, in lieu of the insurance
required by Section A.1 above, insurance otherwise conforming with the
provisions of said Section A.1 except that (i) the amounts of coverage shall not
be required to exceed the amounts of public liability and property damage
insurance from time to time applicable to aircraft owned or operated by Owner of
the same type as the Aircraft which are on the ground and not in operation and
(ii) the scope of the risks covered and the type of insurance shall be the same
as from time to time shall be applicable to aircraft owned or operated by Owner
of the same type which are on the ground and not in operation.

by Owner of the same type as the Aircraft for an amount denominated in United
States Dollars not less than the unpaid Original Amount together with six months
of interest accrued thereon (the "Debt Balance").

         Any policies of insurance carried in accordance with this Section B.1
covering the Aircraft and any policies taken out in substitution or replacement
for any such policies (i) shall name Mortgagee as exclusive loss payee for any
proceeds to be paid under such policies up to an amount equal to the Debt
Balance and (ii) shall provide that (A) in the event of a loss involving
proceeds in excess of the Threshold Amount, the proceeds in respect of such loss
up to an amount equal to the Debt Balance shall be payable to the Mortgagee,
except in the case of a loss with respect to an Engine installed on an airframe
other than the Airframe, in which case Owner (or any Permitted Lessee) shall
endeavor to arrange for any payment of insurance proceeds in respect of such
loss to be held for the account of the Mortgagee whether such payment is made to
Owner (or any Permitted Lessee) or any third party, it being understood and
agreed that in the case of any payment to Mortgagee otherwise than in respect of
an Event of Loss, the Mortgagee shall, upon receipt of evidence satisfactory to
it that the damage giving rise to such payment shall have been repaired or that
such payment shall then be required to pay for repairs then being made, pay the
amount of such payment to Owner or its order, and (B) the entire amount of any
loss involving proceeds of the Threshold Amount or less or the amount of any
proceeds of any loss in excess of the Debt Balance shall be paid to Owner or its
order unless an Event of Default shall have occurred and be continuing and the
insurers have been notified thereof by the Mortgagee. In the case of a loss with
respect to an engine (other than an Engine) installed on the Airframe, Mortgagee
shall hold any payment to it of any insurance proceeds in respect of such loss
for the account of Owner or any other third party that is entitled to receive
such proceeds.

         2. During any period that the Aircraft is on the ground and not in
operation, Owner may carry or cause to be carried, in lieu of the insurance
required by Section B.1 above, insurance otherwise conforming with the
provisions of said Section B.1 except that the scope of the risks and the type
of insurance shall be the same as from time to time applicable to aircraft owned
by Owner of the same type similarly on the ground and not in operation, provided
that Owner shall maintain insurance against risk of loss or damage to the
Aircraft in an amount equal to the Debt Balance during such period that the
Aircraft is on the ground and not in operation.

C. WAR-RISK, HIJACKING AND ALLIED PERILS INSURANCE

         If Owner (or any Permitted Lessee) shall at any time operate or propose
to operate the Aircraft, Airframe or any Engine (i) in any area of recognized
hostilities or (ii) on international routes and war-risk, hijacking or allied
perils insurance is maintained by Owner (or any Permitted Lessee) with respect
to other aircraft owned or operated by Owner (or any Permitted Lessee) on such
routes or in such areas, Owner shall maintain or cause to be maintained
war-risk, hijacking and allied perils insurance of substantially the same type
carried by similar United States commercial air carriers operating the same or
comparable models of aircraft on similar routes or in such areas and in no event
in an amount less than the unpaid Original Amount.


D. GENERAL PROVISIONS

         Any policies of insurance carried in accordance with Sections A, B and
C, including any policies taken out in substitution or replacement for such
policies:


                  (i) shall name Mortgagee, each Note Holder and each Liquidity
         Provider (collectively, the "Additional Insureds"), as its interests
         may appear;

                  (ii) shall apply worldwide and have no territorial
         restrictions or limitations (except only in the case of war, hijacking
         and allied perils insurance required under Section C, which shall apply
         to the fullest extent available in the international insurance market);

                 (iii) shall provide that, in respect of the interests of the
         Additional Insureds in such policies, the insurance shall not be
         invalidated or impaired by any act or omission (including
         misrepresentation and nondisclosure) by Owner (or any Permitted Lessee)
         or any other Person (including, without limitation, use for illegal
         purposes of the Aircraft or any Engine) and shall insure the Additional
         Insureds regardless of any breach or violation of any representation,
         warranty, declaration, term or condition contained in such policies by
         Owner (or any Permitted Lessee);

                  (iv) shall provide that, if the insurers cancel such insurance
         for any reason whatsoever, or if the same is allowed to lapse for
         nonpayment of premium, or if any material change is made in the
         insurance which adversely affects the interest of any of the Additional
         Insureds, such cancellation, lapse or change shall not be effective as
         to the Additional

         Insureds for 30 (seven days in the case of war risk, hijacking and
         allied perils insurance) days after receipt by the Additional Insureds
         of written notice by such insurers of such cancellation, lapse or
         change, provided that if any notice period specified above is not
         reasonably obtainable, such policies shall provide for as long a period
         of prior notice as shall then be reasonably obtainable;

                  (v) shall waive any rights of recourse, subrogation, setoff
         (including for unpaid premiums), recoupment, counterclaim or other
         deduction, whether by attachment or otherwise, against each Additional
         Insured;

                  (vi) shall be primary without right of contribution from any
         other insurance that may be available to any Additional Insured;

                  (vii) shall provide that all of the liability insurance
         provisions thereof, except the limits of liability, shall operate in
         all respects as if a separate policy had been issued covering each
         party insured thereunder;

                  (ix) shall provide that none of the Additional Insureds shall
         be liable for any insurance premium; and

                  (x) shall contain a 50/50% Clause per Lloyd's Aviation
         Underwriters' Association Standard Policy Form AVS 103;

         provided, that any such endorsements may be subject to any limitations
         on endorsements generally prevailing in the airline insurance
         marketplace at the time (e.g. AVN67B).

E. REPORTS AND CERTIFICATES; OTHER INFORMATION

         On or prior to the Closing Date and on or prior to each renewal date of

furnished to Mortgagee insurance certificates describing in reasonable detail
the insurance maintained by Owner hereunder and a report, signed by Owner's or
Permitted Lessee's regular independent insurance broker (the "Insurance
Broker"), stating the opinion of such Insurance Broker that (a) all premiums in
connection with the insurance then due have been paid and (b) such insurance
complies with the terms of this Annex B. To the extent such agreement is
reasonably obtainable Owner will also cause the Insurance Broker to agree to
notify Mortgagee in writing of any default in the payment of any premium and of
any other act or omission on the part of Owner of which it has knowledge and
which might invalidate or render unenforceable, in whole or in part, any
insurance on the Aircraft or Engines or cause the cancellation or termination of
such insurance, and to notify Mortgagee in writing at least 30 days (seven days

in the case of war-risk and allied perils coverage or such shorter period as may
be available in the international insurance market, as the case may be) prior to
the cancellation, lapse or material adverse change of any insurance maintained
pursuant to this Annex B.


F. RIGHT TO PAY PREMIUMS

         Each Additional Insured shall have the rights but not the obligations
of an additional named insured. No Additional Insured shall have any obligation
to pay any premium, commission, assessment or call due on any such insurance
(including reinsurance). Notwithstanding the foregoing, in the event of
cancellation of any required insurance due to the nonpayment of premium,
Mortgagee shall have the option, in its sole discretion, to pay any such premium
in respect of the Aircraft that is due in respect of the coverage pursuant to
this Trust Indenture and to maintain such coverage, as Mortgagee may require,
until the scheduled expiry date of such insurance and, in such event, Owner
shall, upon demand, reimburse Mortgagee for amounts so paid by them.


G. DEDUCTIBLES; SELF-INSURANCE

         Owner may self-insure by way of deductible, premium adjustment or
franchise provisions or otherwise (including, with respect to insurance
maintained pursuant to Section B, insuring for a maximum amount which is less
than the Debt Balance) in the insurance covering the risks required to be
insured against pursuant to Section 4.06 and this Annex B under a program
applicable to all aircraft in Owner's fleet, but in no case shall the aggregate
amount of self-insurance in regard to Section 11 and this Annex B exceed during
any policy year, with respect to all of the aircraft in Owner's fleet
(including, without limitation, the Aircraft), the lesser of (a) 50% of the
largest replacement value of any single aircraft in Owner's fleet and (b) 1-1/2%
of the average aggregate insurable value (during the preceding policy year) of
all aircraft (including, without limitation, the Aircraft) on which Owner
carries insurance, unless an insurance broker of national standing shall certify
that the standard among all other major U.S. airlines is a higher level of
self-insurance, in which case Owner may self-insure to such higher level. In
addition, Owner (and any Permitted Lessee) may self-insure to the extent of any
applicable deductible per aircraft that does not exceed industry standards for
major U.S. airlines.
