     and is duly qualified to do business as a foreign corporation in good
     standing in all jurisdictions in which the nature of the business conducted

     Lessee and its subsidiaries taken as a whole or on the ability of the
     Lessee to perform its obligations under the Lessee Documents;

              (ii)  the execution, delivery and performance by the Lessee of

     Department of Transportation, the FAA, the SEC or any other federal, state

     before the Refunding Date, will have been, duly made, given or
     accomplished;

              (iv)  this Agreement constitutes and each other Lessee Document,

     its consolidated subsidiaries as of such date and the results of operations
     and cash flows for such period and such financial statements do not contain
     any material misstatement or material omission which would render such
     financial statements false or misleading; since June 30, 1995 no event has
     occurred, except for matters disclosed in the financial statements referred
     to above or in Lessee's filings with the SEC on forms 10-Q or 8-K on or
     prior to the date hereof, copies of which have been delivered to the

     Owner Participant and not more than 50 other institutional investors, each
     of whom was offered a portion of the beneficial interests in the Trust
     Estate at private sale for investment; and in the case of each offering by
     the Lessee and its authorized agents, the beneficial interests in the Trust
     Estate have been offered solely for investment and not for resale or
     distribution and the offeree has been a person considered to have such
     knowledge and experience in financial and business matters as to be capable

     statements referred to in clause (v) of this Section 6(a), or (B) legal or
     governmental actions, suits or proceedings which would not, in the Lessee's

     under Section 4041A of ERISA. Neither the Lessee nor any affiliate (i) is
     in the process of terminating any Plan and (ii) has incurred or reasonably
     expects to incur, any material liability under Title IV of ERISA with
     respect to any termination of any employee benefit plan (within the meaning

     to be aggregated with the Lessee under Sections 414(b), (c), (m) or (o) of
     the Code or under Section 4001 of ERISA;

              (xx)  assuming the truth of the representations and warranties

     Pass Through Agreement, the execution and delivery of this Agreement and
     the other Operative Documents and the consummation and performance of the
     transactions described herein and therein will not involve any transaction
     which is subject to the prohibitions of Section 406 of ERISA or in
     connection with which a tax could be imposed pursuant to Section 4975 of
     the Code;

             (xxi)  there are no broker's or underwriter's fees payable in

     other than those of Babcock & Brown Financial Corporation referred to in
     Section 14 (for which the Lessee is responsible) and those payable under
     the Underwriting Agreement to the Underwriters;

            (xxii)  the representations and warranties of the Lessee set forth
     in Section 6 of the Original Participation Agreement were correct on and as

                                        -27-

 
     representations expressly relate solely to a specified earlier date, in
     which case such representations and warranties were correct on and as of
     such earlier date);

           (xxiii)  there has not occurred any event which constitutes a Default
     or an Event of Default under the Lease which is presently continuing and
     there has not occurred any event which constitutes or would with the
     passage of time or the giving of notice, or both, constitute an Event of
     Loss;

be free and clear from the withholding of any Tax imposed by the United States,
any state or local government or taxing authority in the United States, any

     would have been imposed if the presence, location, use or operation of the

     such Indemnitee by any person other than any Affiliate of the Indemnitee
     or, if such Indemnitee is the Indenture Trustee, other than any Holder;

               (v)  imposed on the Owner Trustee in its trust capacity or the
     Indenture Trustee in its trust capacity to the extent that such Taxes
     reduce taxes, fees or other charges which otherwise would have been imposed
     on the Owner Participant, any Holder or any holder of a Pass Through
     Certificate and which are not Taxes indemnified against under this Section
     6(b) or pursuant to the Indemnity Agreement;

              (vi)  which have not been paid but only during the period that
     such Taxes are being contested as provided in this Section 6(b);

             (vii)  imposed on any Indemnitee to the extent that such Taxes
     arise out of or are caused by any act or omission of such Indemnitee where
     such act or omission in breach of express obligations of the Indemnitee
     under the Operative Documents;

            (viii)  imposed on any Indemnitee to the extent that such Taxes
     result from the gross negligence or willful misconduct of such Indemnitee
     (other than gross negligence or willful misconduct imputed by reason of

                                        -30-

 
     such Indemnitee's participation in the transactions contemplated by the
     Operative Documents);

              (ix)  imposed on any Indemnitee as a result of (A) a voluntary
     transfer or other voluntary disposition by the Owner Participant, the Owner
     Trustee or the Indenture Trustee of any interest in the Aircraft or any
     part thereof or the Trust Estate or the Indenture Estate (it being
     understood that a transfer or disposition pursuant to Section 5 (other than
     a sale at fair market value) or Sections 7, 8, 9, 10 or 15 of the Lease or
     the last paragraph of this Section 6(b) (other than a sale at fair market
     value) is not a voluntary transfer or disposition for this purpose), (B)
     with respect to any taxes imposed on the Owner Participant, a transfer or
     disposition by the Owner Participant resulting from bankruptcy or other
     proceedings for the relief of debtors in which the Owner Participant is the
     debtor, whether voluntary or involuntary, of any interest in the Aircraft
     or any part thereof, or the Trust Estate, or (C) a transfer by such
     Indemnitee of all or any part of its interest in a Certificate or a Pass
     Through Certificate unless, in each case, such transfer or disposition
     shall occur at any time while an Event of Default shall have occurred and
     be continuing or shall occur in connection with any substitution,
     replacement, modification, or pooling of the Aircraft, any Engine or any
     Part thereof;

                 (x)  as to which such Indemnitee is indemnified by the Lessee
     pursuant to the Indemnity Agreement;

                (xi)  with respect to any period after the xpiration or earlier
     termination of the Term and the return of the Aircraft or payment in full
     of Stipulated Loss Value or Termination Value, as the case may be, for the
     Aircraft and all Rent due and owing with respect to the Aircraft in each
     case in accordance with the Lease, unless such Taxes relate to events or
     matters occurring prior to or coincidental with such expiration,
     termination, return or payment, as the case may be; and

               (xii)  imposed on the Owner Participant or any person who is a
     "disqualified person", within the meaning of Section 4975(e)(2) of the
     Code, or a "party in interest", within the meaning of Section 3(14) of
     ERISA, by virtue of such person's relationship to the Owner Participant as
     the result of any prohibited transaction, within the meaning of Section
     4975(c)(1) of the Code, occurring with respect to the purchase or holding
     of any Certificate or any Pass Through Certificate or any participation
     interest therein (i) over which purchase or holding the Owner Participant

                                        -31-

 
     (or any Affiliate thereof, which for purposes of this clause (xii) shall
     also include any affiliate within the meaning of the first sentence of Part
     V(c)(3) of Prohibited Transaction Exemption 84-14) has discretion or
     control, or (ii) by an employee benefit plan, within the meaning of Section
     3(3) of ERISA, or individual retirement account or employee benefit plan
     subject to Section 4975 of the Code with respect to which the Owner
     Participant (or any Affiliate thereof) has the power, directly or
     indirectly, to appoint or terminate, or to negotiate the terms of the
     management agreement with, the person or persons having discretion or
     control over such purchase or holding, provided, however, that such
                                            --------  -------
     exclusion shall occur only in the event that the Owner Participant or the
     Affiliate thereof which has the discretion or control described in
     subclause (i) above or which has the power described in subclause (ii)
     above, as the case may be, knows or reasonably should have known that such
     purchase or holding of the Certificates or Pass Through Certificates (or
     participation interests therein) may constitute a prohibited transaction,
     within the meaning of Section 4975(c)(1) of the Code.

          If the Owner Participant reimburses the Owner Trustee or the Indenture
Trustee for any Tax for which indemnification would be required hereunder, the
Lessee will reimburse the Owner Participant therefor.

          The Pass Through Trustee shall withhold any Taxes required to be
withheld on payments to any holder of a Pass Through Certificate who is not a
United States person except to the extent that such holder has furnished
evidence satisfactory to the Pass Through Trustee of any exemption from
withholding Taxes claimed by such holder. The Indenture Trustee shall withhold
any Taxes required to be withheld on payments to any Holder who is not a United
States person except to the extent that such Holder has furnished evidence
satisfactory to the Indenture Trustee of any exemption from withholding Taxes
claimed by such Holder. Notwithstanding the exclusion set forth in subparagraphs
(i) through (xii) of this Section 6(b) or any other provision of any of the
Operative Documents, the Lessee shall indemnify and hold harmless on a net 
after-tax basis the Owner Participant and, if applicable, the Owner Trustee for
any withholding Taxes imposed with respect to such a holder or Holder, as the
case may be, that result from the failure of the Pass Through Trustee or the
Indenture Trustee to properly withhold such Taxes or the failure of the relevant
holder or Holder, as the case may be, to provide the documentation and other
forms necessary to establish an exemption from such Tax. To the extent that the
Lessee is not otherwise reimbursed for such amounts, the Lessee shall be
entitled to recover any amounts paid pursuant to the preceding sentence from the
Pass Through Trustee or the Indenture Trustee, as the case may be, (in its
individual capacity; provided,

                                        -32-

 
however, that notwithstanding anything herein to the contrary, in no event shall
such payment be made out of, or be indemnifiable from, the assets held by the
Pass Through Trustee or the Indenture Trustee on behalf of the holders of the
Pass Through Certificates or the Holders, as the case may be) (plus interest
thereon at the Debt Rate) until such amounts have been recovered in full by the
Lessee. In the event the Indenture Trustee or the Pass Through Trustee is
required to pay any amount in its individual capacity hereunder, it shall have
no recourse to or right of reimbursement from the Indenture Estate, any Pass
Through Trust, the Trust Estate, or any portion of either.

          With respect to any payment or indemnity hereunder, such payment or
indemnity shall include an amount payable to the Indemnitee sufficient to hold
such Indemnitee harmless on an after-tax basis from all Taxes required to be
paid by such Indemnitee with respect to such payment or indemnity under the laws
of any federal, state or local government or taxing authority in or of the
United States, or under the laws of any taxing authority or governmental
subdivision in or of a foreign country; provided that, if any Indemnitee
                                        --------
currently realizes and recognizes a permanent tax benefit by reason of such
payment or indemnity (whether such tax benefit shall be by means of a foreign
tax credit, depreciation or recovery deduction or otherwise) not otherwise taken
into account in computing such payment or indemnity, such Indemnitee shall pay
to the Lessee (but not before the Lessee shall have made all payments then due
to such Indemnitee under the Operative Documents) an amount equal to the sum of
such tax benefit plus any permanent tax benefit realized as the result of any
payment made pursuant to this proviso, when, as, if and to the extent realized
(it being understood that an Indemnitee will not be deemed to realize a
permanent tax benefit by reason of any reduction in the amount of, or credit
against, Taxes for which the Lessee would have been, absent such reduction or
credit, obligated to indemnify such Indemnitee hereunder or under the Indemnity
Agreement, as a result of the payment of, or indemnity for, Taxes for which the
Lessee has previously paid an indemnity hereunder); provided, however, that such
                                                    --------  -------
payment by an Indemnitee shall not exceed the lesser of (x) the sum of such tax
benefit plus any other permanent tax benefit realized by such Indemnitee as the
result of any payment made by such Indemnitee pursuant to this sentence and (y)
the amount of all payments pursuant to this Section 6(b) by the Lessee to such
Indemnitee (and the excess, if any, of the amount described in clause (x) over
the amount described in clause (y) shall be carried forward and applied to
reduce pro tanto any subsequent obligations of the Lessee to make payments
       ---------
pursuant to this Section 6(b), it being intended that no Indemnitee should
realize a net tax benefit pursuant to this Section 6(b) unless the Lessee shall
first have been made whole for any payments by it to such Indemnitee pursuant to
this Section 6(b)); provided, further, that if, at the time such payment shall
                    --------  -------
be due to the Lessee an Event of Default or Payment Default shall have occurred
and be continuing, such payment shall not be made to the Lessee unless and until
all

                                        -33-

 
Events of Default or Payment Defaults shall have been cured by the Lessee. Each
such Indemnitee shall in good faith use reasonable efforts in filing its tax
returns and in dealing with taxing authorities to seek and claim any such tax
benefit. Any Taxes that are imposed on any Indemnitee as a result of the loss,
disallowance, recapture or reduction of such tax benefit referred to in the next
preceding sentence in a taxable year subsequent to the year of allowance and
utilization by such Indemnitee (including the expiration of any tax credit
carryovers or carrybacks of such Indemnitee that would not otherwise have
expired) shall be deemed a Tax indemnified pursuant to the provisions of this
Section 6(b). In determining the order in which the Indemnitee utilizes any
foreign taxes as a credit against the Indemnitee's United States income taxes,
the Indemnitee shall be deemed to utilize (A) first, all foreign taxes other
than those described in clause (B) below; provided, however, that such other
                                          --------  -------
foreign taxes which are carried back to the taxable year for which a
determination is being made shall be deemed utilized after the foreign taxes
described in clause (B) below, and (B) then, on a pro rata basis, all foreign
taxes in connection with equipment leasing transactions with respect to which
and to the extent that the Indemnitee is entitled to obtain indemnification
pursuant to an indemnification provision contained in any lease, financing
document, participation agreement, or indemnification agreement (including this
Agreement) other than any such transaction in which there is an express
provision that credits are deemed utilized on a basis more or less favorable
than pro rata; provided further, however, that for purposes of the two preceding
     --- ----  -------- -------  -------
sentences (except to the extent provided in the immediately preceding proviso) a
reduction in taxes shall be considered attributable to a foreign tax credit
carryover or carryback arising from a recovery by the Indemnitee of foreign tax
credits in respect of which the Lessee has previously paid an indemnity
hereunder only to the extent that all other carryovers and carrybacks of foreign
tax credits of the Indemnitee have been fully used by the Indemnitee.

          If written claim is made against any Indemnitee for any such Tax
referred to in this Section 6(b), the Indemnitee shall promptly notify the
Lessee of the Indemnitee's receipt of such claim; provided, however, that the
                                                  --------  -------
failure of the Indemnitee to so notify the Lessee shall not preclude any
indemnity hereunder unless and to the extent that the Lessee's right to effect
its contest rights hereunder has been materially impaired by such failure. If
requested by the Lessee in writing, such Indemnitee shall in good faith contest
the validity, applicability or amount of such Tax provided such Tax is one with
respect to which the Lessee has agreed in writing that it would be required to
indemnify the Indemnitee under this Section 6 provided that such agreement shall
be of no force and effect if the contest is ultimately resolved on an
articulated basis which clearly does not constitute a basis for indemnification
hereunder. Such Indemnitee shall consult with and keep the Lessee informed as to
the progress of any action, suit or proceeding by such Indemnitee contesting

                                        -34-

 
the validity, applicability or amount of such Tax and, upon the request of such
Indemnitee, the Lessee shall assume responsibility for contesting the validity,
applicability or amount of such Tax in the name of the Indemnitee or in the name
of the Lessee, if permissible under applicable law; provided that (i) the Lessee
                                                    --------
shall not be obligated to bring any action, suit or proceeding or to prosecute
any such contest, except in its sole discretion; (ii) in the event of any such
contest by the Lessee, such Indemnitee shall cooperate with the Lessee by
providing to the Lessee all documents (or portions thereof), reports and other
information relevant thereto in the Indemnitee's possession (which documents (or
portions thereof), reports and other information will be disclosed by the Lessee
only for the purposes of such contest), by resisting payment of such Tax if
lawful and practicable and, provided that nonpayment of the same would not
result in any material danger of sale, forfeiture, loss of use of the Aircraft,
the Airframe or any Engine or any risk of criminal liability, by not paying the
same except under protest, if protest is necessary and proper; (iii) if the
Lessee shall not be qualified to contest such Tax or shall not be requested to
do so by such Indemnitee, such Indemnitee shall, upon receipt of indemnity
satisfactory to it and upon the written request and at the expense of the Lessee
reimbursed to such Indemnitee on reasonable demand and on an after-tax basis
(including, without limitation, all reasonable costs, expenses, losses, legal
and accountants' fees and disbursements, penalties and interest), in good faith
contest in the name of such Indemnitee the validity; applicability or amount of
such Tax by, in such Indemnitee's discretion, (A) resisting payment thereof if
practicable and consistent with applicable administrative or judicial procedures
(B) not paying the same except under protest, if protest is necessary and
proper, and provided that non-payment of the same would not result in any
material danger of sale, forfeiture, or loss of use of the Aircraft, the
Airframe or any Engine or any risk of criminal liability or (C) paying the same
and using reasonable efforts to obtain a refund thereof in appropriate
administrative and judicial proceedings. If an Indemnitee contests a Tax by
making a payment thereof, then the Lessee shall advance on an interest free
basis and shall indemnify on an after-tax basis such Indemnitee against any
adverse tax consequences resulting from such advance, an amount equal to the
Taxes and any penalties, additions to tax, fines and interest thereon that are
paid by such Indemnitee in connection with such contest. Notwithstanding
anything contained in this Section 6(b), an Indemnitee will not be required to
contest, or to continue to contest, the validity, applicability or amount of any
Tax (or portion thereof) (v) in the nature of an income or franchise tax imposed
on the Owner Participant or Owner Trustee unless tax counsel selected by the
Owner Participant and reasonably acceptable to the Lessee is of the opinion that
there is a Reasonable Basis (as defined in the Indemnity Agreement) for pursuit
of such contest and the amount at issue exceeds $12,500, (x) if such Indemnitee
waives its right to indemnity hereunder with respect to such Tax (or such
portion thereof) or (y) if an

                                        -35-

 
Event of Default or a Payment Default has occurred and is continuing, unless the
Lessee provides such Indemnitee with security in a manner satisfactory to such
Indemnitee within such Indemnitee's reasonable discretion. Notwithstanding the
foregoing, if the contest also involves other Taxes which are not required to be
indemnified by the Lessee pursuant to this Section 6(b) ("Non-Indemnified
Items"), then, such Indemnitee shall not discriminate against such Tax in favor
of any Non-Indemnified Items and, unless one of the conditions referred to in
clause (x) or (y) of the previous sentence exists, shall not settle such Tax,
without the consent of the Lessee (except with respect to Non-Indemnified
Items), which consent shall not be unreasonably withheld or delayed given all
the facts and circumstances. All costs and expenses of any contest by the Lessee
and all reasonable costs and expenses of any contest by any Indemnitee shall be
borne by the Lessee (except with respect to Non-Indemnified Items), which costs
and expenses shall be paid promptly and on an after-tax basis after receipt of
notice. If any Indemnitee shall obtain a refund of all or any part of such Tax
paid by the lessee or for which the Lessee shall have reimbursed such
Indemnitee, such Indemnitee shall pay promptly to the Lessee an amount equal to
the sum of (i) the amount of such refund, including interest, if any, reduced by
the Taxes imposed on such Indemnitee by reason of the receipt or accrual of such
refund and/or interest plus (ii) the amount of Taxes saved by such Indemnitee by
reason of the deduction of its payment over to the Lessee of the sum of amounts
in clause (i) and this clause (ii); provided, however, in no event shall such
                                    --------  -------
amount payable pursuant to this sentence exceed the amount of such Tax payment
by the Lessee to such Indemnitee (plus any other payment by the Lessee to such
Indemnitee theretofore made pursuant to this Section 6(b) to the extent not
previously taken into account under this Section 6(b)) and any excess amount
shall be carried forward to reduce pro tanto any future obligations of the
                                   --- -----
Lessee to such Indemnitee under this Section 6(b); provided that, if at the time
                                                   --------
such payment shall be due to the Lessee an Event of Default shall have occurred
and be continuing, such payment shall not be made to the Lessee unless and until
all Events of Default shall have been cured. Any amount of refund with respect
to which such Indemnitee has made a payment to the Lessee as required hereunder
that the Indemnitee is required to repay to any taxing authority shall be
treated as a Tax for which the Lessee is obligated to indemnify such Indemnitee
pursuant to the provisions of this Section 6(b). The Lessee shall not be deemed
to be in default under any of the above indemnification provisions so long as it
or any Indemnitee shall diligently prosecute such contest in good faith and in
accordance with the terms of this Section 6(b). Upon final determination or
settlement of a contest, any unpaid Taxes plus other amounts owed hereunder
shall be payable by the Lessee no later than 30 days after such final
determination or settlement.

                                        -36-

 
          Each Indemnitee shall promptly forward to the Lessee any written
notice, bill, or advice received by it concerning any indemnified Tax. Subject
to the provisions of the last sentence of the preceding paragraph, the Lessee
shall pay any amount for which it is liable pursuant to this Section 6(b)
(without regard to Section 6(b)(vi)), directly to the appropriate taxing
authority if legally permissible or, upon demand of an Indemnitee, to such
Indemnitee within thirty (30) Business Days of such demand, but in no event more
than ten (10) Business Days nor less than five (5) Business Days (provided that
if the Lessee has not received demand within a reasonable time prior to such
date, the Lessees shall make such payment promptly within a reasonable time
after receipt of such demand) prior to the date the Tax to which such amount
payable hereunder relates is due. Within thirty (30) days after the date of each
payment by the Lessee of any Tax, the Lessee shall furnish to the appropriate
Indemnitee the original or a certified copy of a receipt for the Lessee's
payment of such Tax or such other evidence of payment of such Tax as is
acceptable to such Indemnitee. The Lessee shall also furnish promptly upon
request such data as any Indemnitee may reasonably request to enable such
Indemnitee to comply with the Indemnitee's filing, audit or litigation
requirements in any taxing jurisdiction.

          If any report, return or statement is required to be filed with
respect to any Tax which is subject to indemnification under this Section 6(b)
(without regard to Section 6(b)(vi)), the Lessee shall timely file the same
(except for any such report, return or statement which the Indemnitee has
notified the Lessee that the Indemnitee intends to file or for which the
Indemnitee is required by law to file in its own name). The Lessee shall either
file such report, return or statement so as to show the ownership of the
Aircraft in the Owner Trustee (unless consented to otherwise by Owner
Participant) and send a copy of such report, return or statement to the
Indemnitee, and the Owner Trustee if the Indemnitee is not the Owner Trustee,
or, where the Lessee is not permitted to file such report, return or statement,
it shall notify the Indemnitee of such requirement and prepare and deliver such
report, return or statement to the Indemnitee in a manner satisfactory to such
Indemnitee within a reasonable time prior to the time such report, return or
statement is to be filed.

          If the Lessee is required to indemnify under this Agreement for any
value added tax (or would be required to indemnify pursuant to legislation
scheduled to go into effect), and if in the reasonable judgment of the Lessee
such indemnification might prove to be burdensome to the Lessee, the Lessee
shall have the option upon the delivery of thirty (30) days' prior written
notice to elect to purchase the Aircraft or the Owner Participant's interest
therein at a purchase price, and following procedures substantially identical to
those, set forth in Section 16(b)(i) or (ii) hereof unless prior to the
completion of such purchase the Owner Participant shall have waived such
indemnity by the Lessee and shall have undertaken in a manner reasonably
satisfactory to the Lessee to bear such value added

                                        -37-

 
tax. If the Owner Participant incurs any value added tax on the Aircraft or the
Rent not indemnified under this Section 6(b) (or would incur such tax pursuant
to legislation scheduled to go into effect), and if such Tax might in the
reasonable judgment of the Owner Participant prove to be burdensome to the Owner
Participant, then the Owner Participant may, by delivery of written notice to
the Lessee declare an Event of Loss to have occurred as of the date of such
notice, and the provisions of Section 10(a)(i) of the Lease shall become
applicable unless Lessee shall have assumed liability for such tax hereunder (it
being understood that the provisions of Section 10(a)(ii) of the Lease shall not
be available with respect to an Event of Loss declared pursuant to this
paragraph).

          (c)  General Indemnity.  Whether or not any of the transactions
               -----------------
contemplated hereby shall be consummated, the Lessee hereby agrees to assume,
and does hereby assume, liability for, and does hereby indemnify and agree to
protect, defend, save and keep harmless each Indemnitee and their respective
successors, assigns, directors, officers, agents, representatives and servants,
from and against, any and all liabilities, obligations, losses, damages,
penalties, claims, actions, suits, costs, expenses and disbursements (including
reasonable legal fees and expenses and costs and expenses relating to

kind and nature whatsoever (other than any Taxes), which may be imposed on,
incurred by or asserted against any Indemnitee or its respective successors,
assigns, directors, officers, agents, representatives or servants, by any person
other than the Lessee (but including the Lessee to the extent that such cost or
expense arises from an unsuccessful assertion of a claim by the Lessee), in any

Supplement, the Indenture, the Original Loan Certificate, the Interim
Refinancing Loan Certificate, the Certificates, the Pass Through Certificates,

the Term and the return of the Aircraft in compliance with the provisions of
Section 5 of the Lease (including any claim for patent, trademark or copyright
infringement, any claim based on theories of negligence, warranty, absolute
liability, latent or other defects, strict liability, statutory liability or

relating to or arising out of the offer or sale of any interest in the Trust
Estate or the Trust Agreement or any similar interest or in any way relating to

the Indenture Estate (including, without limitation, any claim arising out of
the Securities Act, the Exchange Act, or any other Federal or state statute, law
or regulation, or at common law or otherwise relating to securities
(collectively "Securities Liabilities")), or the action or inaction of the Owner
Trustee or the Indenture Trustee as trustees (including, without limitation, any
claim arising out of the Owner Participant's obligation under Section 8.01 of
the Trust Agreement); provided, however, that the Lessee shall not be required
                      --------  -------
to indemnify (i) the Indenture Trustee (individually or otherwise), the Original
Loan Participant or the Interim Refinancing Loan Participant (including, in each
case, the respective successors, assigns, directors, officers, agents and
servants of the Indenture Trustee, the Original Loan Participant or the Interim
Refinancing Loan Participant, as the case may be) (a) for liability arising from
such Indemnitee's own gross negligence or willful misconduct or (b) for the
inaccuracy of any representation by it or breach by such Indemnitee of any
warranty or covenant set forth in any Operative Document, or (ii) the Owner
Trustee (individually or otherwise and including its successors, assigns,
directors, officers, agents and servants) (a) for its own willful misconduct or
gross negligence, (b) for the inaccuracy of any representation or breach of any
warranty or covenant, made or undertaken in its individual capacity, set forth
in any Operative Document, (c) for taxes, fees or other charges on, based on, or
measured by, any fees, commissions or compensation received by the Owner Trustee
in its individual capacity in connection with the transactions contemplated by
any Operative Document, (d) for any failure to use ordinary care in receiving or
disbursing funds or in connection with its obligation to invest funds pursuant
to Section 1 of this Participation Agreement, Section 24 of the Lease, or
Section 3.02 of the Trust Agreement, or (e) for any liability on the part of the
Owner Trustee arising out of its negligence or willful or negligent misconduct
in connection with its obligations under Sections 6.01, 6.06 or 10.02 of the
Trust Agreement or Section 3.05(b)(iii) of the Indenture, it being understood
that nothing in this clause (ii) shall derogate from Lessee's indemnification of
the Indenture Estate and the Trust Estate hereunder; and provided, further,
                                                         --------  -------

                                        -39-

 
that, except as and to the extent attributable to default by the Lessee in
performing or observing its obligations hereunder or under the Lease or breach
by the Lessee of any of its representations or warranties herein or therein, the
Lessee shall not be required to indemnify any of the following:

               (i)  the Owner Participant against any and all liabilities,
     obligations, losses, damages, penalties, claims, actions, suits, costs,
     expenses and disbursements (including legal fees and expenses) of any kind
     and nature whatsoever which may be imposed on, incurred by or asserted
     against the Owner Participant to the extent that the same are so imposed,
     incurred or asserted as a result of a default on its part in the observance
     or performance of the express terms and provisions to be observed and
     performed by the Owner Participant in the Trust Agreement or this
     Agreement;

              (ii)  any Indemnitee against any expense to the extent required to
     be paid by such Indemnitee pursuant to Section 14 hereof, unless such
     expense is required to be paid by Lessee hereunder;

             (iii)  the Owner Participant or any person who is a "disqualified
     person", within the meaning of Section 4975(e)(2) of the Code, or a "party
     in interest", within the meaning of Section 3(14) of ERISA, by virtue of
     such person's relationship to the Owner Participant against any and all
     liabilities, obligations, losses, damages, penalties, claims, actions,
     suits, costs, expenses and disbursement (including legal fees and expenses)
     of any kind and nature whatsoever which may be imposed on, incurred by or
     asserted against the Owner Participant or any person who is a "disqualified
     person", within the meaning of Section 4975(e)(2) of the Code, or a "party
     in interest," within the meaning of Section 3(14) of ERISA, by virtue of
     such person's relationship to the Owner Participant, as the case may be,
     resulting from any prohibited transaction, within the meaning of Section
     4975(c)(1) of the Code, occurring with respect to the purchase or holding
     of any Certificate or Pass Through Certificate or any participation
     interest in either therein (i) over which purchase or holding the Owner
     Participant (or any Affiliate thereof, which for purposes of this clause
     (iii) shall also include any affiliate within the meaning of the first
     sentence Part V(c)(3) of Prohibited Transaction Exemption 84-14) has
     discretion or control, or (ii) by an employee benefit plan, within the
     meaning of Section 3(3) of ERISA, or individual retirement account or
     employee benefit plan subject to Section 4975 of the Code with respect to
     which the Owner Participant (or any Affiliate thereof) has the power,
     directly or indirectly, to

                                        -40-

 
     appoint or terminate or to negotiate the terms of the management agreement
     with, the person or persons having discretion or control over such purchase
     or holding, provided, however, that such exclusion shall occur only in the
                 --------  -------
     event that the Owner Participant or the Affiliate thereof which has the
     discretion or control described in subclause (ii) above, as the case may
     be, knows or reasonably should have known that such purchase or holding of
     the Certificates or Pass Through Certificates (or participation interest in
     either therein) may constitute a prohibited transaction, within the meaning
     of the Section 4975(c) (1) of the Code; or

              (iv)  any Indemnitee against any and all liabilities, obligations,
     losses, damages, penalties, claims, actions, suits, costs, expenses and
     disbursements (including legal fees and expenses) of any kind and nature
     whatsoever which may be imposed on, made by or asserted against such
     Indemnitee to the extent that the same are so imposed, made or asserted by
     reason of (A) any voluntary transfer or voluntary disposition by such
     Indemnitee (it being understood that a transfer or disposition pursuant to
     Sections 5 (other than a sale at fair market value), 7, 8, 9, 10 or 15 of
     the Lease is not a voluntary transfer or disposition for this purpose) or
     (B) a transfer or disposition by such Indemnitee resulting from bankruptcy
     or other proceedings for the relief of debtors in which such Indemnitee is
     the debtor, whether voluntary or involuntary, of any interest in the
     Aircraft or any part thereof, or the Trust Estate, unless, in each case,
     such transfer or disposition occurs at any time while an Event of Default
     has occurred and is continuing.

Nothing herein shall be deemed to constitute an assumption by the Lessee of the
obligations of the Owner Trustee upon, or a guarantee by the Lessee of, the
principal of, or interest upon, the Certificates or the Pass Through
Certificates or to constitute any guarantee of any residual value of the
Aircraft. Nothing herein shall be deemed to constitute an agreement by the
Lessee that the Pass Through Certificates represent an interest in, or
obligation of, the Lessee. Payments due from the Lessee to each Indemnitee
pursuant to this Section 6(c) shall be made directly to such Indemnitee. This
Agreement constitutes a separate agreement with respect to each Indemnitee and
is enforceable directly by each such Indemnitee. In the event the Lessee is
required to make any payment under this Section 6(c), the Lessee shall pay the
person indemnified an amount which, after deduction of all taxes required to be
paid by said person in respect of the receipt thereof under the laws of the
United States or of any State or of any political subdivision thereof or therein
or of any foreign country or of any political subdivision thereof or therein
(after giving credit for any actual current savings in respect of any such taxes
by reason of deductions, credits or allowances in

                                        -41-

 
     respect of the payment of the expense indemnified against, and of any other
     such taxes), shall be equal to the amount of such payment.

          If the Lessee has knowledge of any material claim or liability
indemnified against under this Section 6(c), it shall give prompt written notice
thereof to all Indemnitees, and if any Indemnitee shall have any such knowledge,
it shall give prompt written notice to the Lessee. In case any action, suit or
proceeding shall be brought against any Indemnitee under this Section 6(c), such
Indemnitee shall notify the Lessee of the commencement thereof, and the Lessee
may, at its expense, participate in, and, to the extent that it shall wish
(subject to the provisions of the following paragraph), assume the defense
thereof, with counsel satisfactory to such Indemnitee. With respect to any
amount which the Lessee is requested by an Indemnitee to pay by reason of this
Section 6(c), the Indemnitee shall, if requested by the Lessee and prior to any
payment, submit such additional information to the Lessee as the Lessee may
reasonably request properly to substantiate the requested payment.
Notwithstanding the foregoing, the failure of any Indemnitee to notify the
Lessee as provided in this Section 6(c) shall not relieve the Lessee from any
liability it may have to such party, except to the extent that any such failure
results in any material increase in or inability to mitigate the liability of
the Lessee hereunder.

          The Lessee or its insurers shall have the right to investigate or
(provided that the Lessee or its insurers shall agree not to dispute liability
hereunder or under any insurance policies pursuant to which coverage is sought
and provided that the Lessee shall have used good faith efforts to consult with
the relevant Indemnitee) defend or compromise any claim for which
indemnification is sought pursuant to this Section 6(c), and each Indemnitee
shall cooperate with the Lessee or its insurers with respect thereto provided,
                                                                     --------
however, that the Lessee shall not be entitled to control the defense of or
- -------
compromise such claim (i) during the continuance of any Event of Default, (ii)
if and to the extent that any Indemnitee has certified that, in its reasonable
judgment, such claim involves the potential imposition of criminal liability on
such Indemnitee or (iii) if such defense or compromise would involve a material
risk of the sale, forfeiture or loss of, or the creation of any Lien (other than
a Permitted Lien) on, the Aircraft, the Airframe, the Indenture Estate or the
Trust Estate, unless the Lessee shall have posted a bond or other security
satisfactory to the relevant Indemnitee with respect to such risk. The Lessee
will provide the Indemnitee with such information not within the control of such
Indemnitee, as is in the Lessee's control or is reasonably available to the
Lessee, which such Indemnitee may reasonably request and will otherwise
cooperate with such Indemnitee so as to enable such Indemnitee to fulfill its
obligations under this paragraph. Where the Lessee or any of its insurers
undertakes the defense of an Indemnitee with respect to a claim and so long as,
but only so

                                        -42-

 
long as, the Lessee is entitled to control such defense, no additional legal
fees or expenses of such Indemnitee in connection with the defense of such claim
will be indemnified hereunder unless such fees or expenses were incurred at the
request of the Lessee or such insurers; provided, however, that if (i) in the
                                        --------  -------
reasonable opinion of such Indemnitee, an actual or potential material conflict
of interest exists where it is advisable for such Indemnitee to be represented
by separate counsel or (ii) such Indemnitee has been indicted or otherwise
charged in a criminal complaint and such Indemnitee informs the Lessee that such
Indemnitee desires to be represented by separate counsel, the reasonable fees
and expenses of such separate counsel will be borne by the Lessee. Nothing in
this Section 6(c) shall be deemed to require an Indemnitee to contest any claim
or to assume responsibility for or control of any judicial proceeding with
respect thereto.

          (d)  Adjustment of Stipulated Loss Value and Termination Value.  If
               ---------------------------------------------------------
any amount is paid by the Lessee to the Owner Participant pursuant to the
Indemnity Agreement, the percentages for Stipulated Loss Value and Termination
Value set forth in Exhibit B to the Lease and Schedule 1 to the Indemnity
Agreement shall be recomputed in the manner set forth in Section 3(e) of the
Lease.

          (e)  Survival of Indemnities.  The representations, warranties,
               -----------------------
indemnities and agreements of each of the parties provided for in this
Agreement, and each party's obligations under any and all thereof, shall survive
the payment of the commitments by the Owner Participant, the Original Loan
Participant, the Interim Refinancing Loan Participant, and the refinancing of
the Interim Refinancing Loan Certificate on the Refunding Date, the return of
the Aircraft and the expiration or other termination of this Agreement, the
Trust Agreement, the Indenture and the Lease but, as to such indemnities, only
with respect to losses, liabilities, obligations, damages, penalties, claims,
actions, suits, costs, expenses and disbursements caused by events occurring or
existing prior to or incurred in the process of or simultaneous with (i) the
return or disposition of the Aircraft under Section 5 or Section 15 of the
Lease, or (ii) the termination of the Lease or the Indenture or, if later, the
return of the Aircraft.

          (f)  Effect of Other Indemnities.  The Lessee's obligations under the
               ----------------------------
indemnities provided for in this Agreement shall be those of a primary obligor
whether or not the person indemnified shall also be indemnified with respect to
the same matter under the terms of this Agreement, the Lease, the Indenture, the
Trust Agreement, or any other document or instrument, and the person seeking
indemnification from the Lessee pursuant to any provision of this Agreement may
proceed directly against the Lessee without first seeking to enforce any other
right of indemnification. Upon the payment in full by the Lessee of any
indemnity provided for under this Agreement, the Lessee

                                        -43-

 
shall be, to the extent permitted by law, subrogated to any right of the person
indemnified, other than with respect to any of such Indemnitee's insurance
policies or in connection with any indemnity claim the person indemnified may
have against the Owner Participant or the Lessor, in respect of the matter as to
which such indemnity was paid.

          (g)  Interest.  The Lessee will pay to each Indemnitee on demand, to
               ---------
the extent permitted by applicable law, interest on any amount of indemnity not
paid when due pursuant to this Section 6 until the same shall be paid, at the
Past Due Rate.

          (h)  Continuing Obligations.  Notwithstanding anything contained
               -----------------------
herein or in any other Operative Document to the contrary, Lessor and the Owner
Participant shall retain any and all of their respective rights, and Lessee
shall continue to be fully responsible for all of its obligations, arising out
of or otherwise relating to any claims under any of the Original Documents which
are based upon any breach by Lessee prior to or on the Refunding Date (whether
or not such breach is known as of such Date) of any representation, warranty or
covenant of Lessee contained in any of the Original Documents.

          Section 7.  Representations, Warranties and Covenants.  (a) The Owner
                      ------------------------------------------
Participant represents and warrants that neither it nor anyone it has authorized
to act on its behalf has directly or indirectly offered any Certificate or
Certificates or any interest in and to the Indenture Estate or the Trust Estate
or any similar securities relating to the Aircraft for sale to, or solicited any
offer to acquire any of the same from, anyone. The Owner Participant represents
and warrants that its interest in and to the Trust Estate and the Trust
Agreement was acquired for its own account and was purchased and is presently
held for investment and not with a present view to any resale or distribution
thereof. The Owner Participant is not hereby deemed to have made any
representation that it will not at any time in the future resell or transfer
such interest.

          (b)  The Owner Trustee, in its individual capacity with respect to
clauses (i) through (xi) below and not in its individual capacity but solely as
Owner Trustee with respect to clause (xii) below, represents and warrants as of
the date hereof (except as otherwise provided) and as of the Refunding Date
that:

               (i)  neither the Owner Trustee (in its individual capacity and/or
     as Owner Trustee) nor anyone it has authorized to act on its behalf has
     directly or indirectly offered any Certificate or Pass Through Certificates
     or any interest in and to the Indenture Estate or the Trust Estate or any
     similar securities relating to the Aircraft for sale to, or solicited any
     offer to acquire any of the same from, anyone;

                                        -44-

 
              (ii)  its chief executive office (as that term is used in Article
     9 of the Uniform Commercial Code) is located at 1100 North Market Street,
     Rodney Square North, Wilmington, Delaware, 19890-0001 and that it will give
     the parties hereto at least 30 days' prior written notice of any change of
     the location of such office;

             (iii)  no Lessor's Lien on any part of the Trust Estate or any part
     of the Indenture Estate exists which was created, granted or assumed by the
     Owner Trustee in its individual capacity or which resulted from claims
     against the Owner Trustee in its individual capacity not related to the
     transactions contemplated by the Operative Documents;

              (iv)  on the Delivery Date the Owner Trustee received whatever
     title to the Aircraft that was conveyed to it by the Lessee, and to its
     knowledge, the Owner Trustee has whatever title to the Aircraft that was
     conveyed to it by the Lessee (it being understood that the Owner Trustee
     shall not be deemed to have any such knowledge in the absence of actual
     knowledge by one of its Responsible Officers);

               (v)  it is a banking corporation duly organized and validly
     existing in good standing under the laws of the State of Delaware and has
     the corporate power and authority to carry on its present business and
     operations and to enter into and perform its obligations under this
     Agreement, the Trust Agreement, the Indenture, the Lease and the
     Certificates (the "Financing Documents");

              (vi)  assuming the due authorization, execution and delivery of
     the Trust Agreement by the Owner Participant, each of the Financing
     Documents has been duly authorized by all necessary corporate action on its
     part, and neither the execution and delivery thereof by the Owner Trustee
     either in its individual capacity or as Owner Trustee nor its performance
     of any of the terms and provisions thereof will require shareholder
     approval or the approval or consent of any trustee or holder of any
     indebtedness or obligation of the Owner Trustee in its individual capacity
     or violate any Federal or State of Delaware law, rule or regulation
     relating to its banking or trust powers or contravene or result in any
     breach of, or constitute any default under its charter or by-laws or any
     judgment or order binding on it or the provisions of any indenture,
     mortgage, contract or other agreement to which it is a party or by which it
     or its properties may be bound or affected or contravene any judgment or
     order applicable or binding on it;

                                     -45-

 
             (vii)  assuming that the Trust Agreement will, on the Refunding
     Date, constitute the legal, valid and binding obligation of the Owner
     Participant, the Trust Agreement will, on the Refunding Date, constitute
     the legal, valid and binding obligation of the Owner Trustee in its
     individual capacity, enforceable in accordance with its terms, subject to
     applicable bankruptcy, reorganization, insolvency, moratorium or other
     similar laws or equitable principles affecting creditors' rights generally
     from time to time in effect; with respect to each of the other Financing
     Documents, to the best of its knowledge in reliance upon the advice of its
     counsel, it has no reason to believe (assuming due authorization, execution
     and delivery of each of such other Financing Documents by each of the
     parties thereto other than the Owner Trustee (in its individual capacity
     and/or as Owner Trustee, as the case may be) and that such other Financing
     Documents will, on the Refunding Date, constitute the valid and legally
     binding obligations of each of the parties thereto other than the Owner
     Trustee) that each such other Financing Document will not, on the Refunding
     Date, constitute a valid and legally binding obligation of the Owner
     Trustee (in its individual capacity and/or as Owner Trustee, as the case
     may be), enforceable against the Owner Trustee (in its individual capacity
     and/or as Owner Trustee, as the case may be) in accordance with its terms;

            (viii)  there are no pending or, to the knowledge of the Owner
     Trustee, threatened actions or proceedings against the Owner Trustee (in
     its individual capacity and/or as Owner Trustee, as the case may be) before
     any court, administrative agency or tribunal which, if determined adversely
     to the Owner Trustee (in its individual capacity and/or as Owner Trustee,
     as the case may be), would materially adversely affect the ability of the
     Owner Trustee, individually or as Owner Trustee, as the case may be, to
     perform its obligations under any of the Financing Documents to which it is
     a party. The Owner Trustee has no actual knowledge of any pending or
     threatened actions or proceedings before any court, administrative agency
     or tribunal involving it in its capacity as Owner Trustee;

              (ix)  no consent, approval, order or authorization of, giving of
     notice to, or registration with, or taking of any other action in respect
     of, any governmental authority or agency of the State of Delaware or any
     Federal governmental authority or agency of the United States of America
     regulating the banking or trust powers of the Owner Trustee, in its
     individual capacity is required for the execution and delivery of, or the
     carrying out by, the Owner Trustee in its

                                        -46-

 
     individual capacity or as Owner Trustee, as the case may be, of any of the
     transactions contemplated hereby or by the Trust Agreement or of any of the
     other Financing Documents, other than any such consent, approval, order,
     authorization, registration, notice or action as has been duly obtained,
     given or taken and is in full force and effect;

               (x)  there are no Lessor's Liens which constitute a Lien against
     any or all of the Trust Estate or the Indenture Estate;

              (xi)  its representations and warranties set forth in Section 7 of
     the Original Participation Agreement were correct on and as of the Delivery
     Date (except to the extent that such representations expressly relate
     solely to a specified earlier date, in which case such representations and
     warranties were correct on and as of such earlier date); and

             (xii)  the Owner Trustee has whatever title to the Aircraft that
     was conveyed to it by the Lessee.

     carry out the transactions contemplated hereby and thereby;

             (iii)  it has duly authorized, executed and delivered the Owner
     Participant Documents and, assuming due execution of such documents by the
     other parties thereto, each of the Owner Participant Documents constitutes

     against the Owner Participant in accordance with its terms except as such
     enforceability may be limited by general equitable principles and by
     applicable bankruptcy, insolvency, reorganization, moratorium or similar
     laws affecting creditors' rights generally from time to time in effect and
     assuming with respect to ERISA, the truth of the representations and
     warranties made by the Lessee in Sections 6(a)(xix) and 6(a)(xx) and by the

                                        -47-

 
     Participation Agreement, and assuming compliance with Section 10.06 of the
     Indenture and Section 6.06 of the Pass Through Agreement;

              (iv)  the execution, delivery and performance by the Owner

     other agreement or instrument to which it is a party or by which it is

     6(a)(xx) and by the Original Loan Participant and the Interim Refinancing
     Loan Participant in Section 7(e) of the Original Participation Agreement,
     and assuming compliance with Section 10.06 of the Indenture and Section
     6.06 of the Pass Through Agreement, of any law or governmental rule or
     regulation applicable to the Owner Participant;

               (v)  neither the execution and delivery by the Owner Participant
     of any of the Owner Participant Documents nor the consummation by the Owner
     Participant of any of the transactions contemplated thereby require the
     Owner Participant to obtain the consent or approval of, give notice to, or
     register with, or take any other action with respect to, any state or
     federal agency or authority except such consents as have been obtained;

              (vi)  there are no Owner Participant's Liens with respect to any

     set forth in Section 7 of the Original Participation Agreement were correct
     on and as of the Delivery Date (except to the extent that such

     which case such representations and warranties were correct on and as of
     such earlier date).

     Notwithstanding the foregoing, except as to matters concerning its
citizenship, the Owner Participant makes no representation or warranty with
respect to laws, rules or regulations relating to aviation (including the Act)
or the nature or condition of the equipment purchased by the Owner Trustee
pursuant to the Original Participation Agreement.

          (d)  Notwithstanding any other provision of this Agreement or any
other Operative Document, each of the Owner Trustee in its individual capacity,

warrants that as of the Refunding Date:

               (i)  no Indenture Trustee's Lien on any part of the Indenture
     Estate exists;

              (ii)  it is a validly existing banking corporation duly organized
     under the laws of the State of New York and has the corporate power and
     authority to enter into and perform its obligations under the Indenture and

     delivered on the Refunding Date;

             (iii)  this Agreement, the Indenture, and the authentication of the
     Certificates to be delivered on the Refunding Date have been duly
     authorized by all necessary corporate action on its part, and neither the
     execution and delivery thereof nor its performance of any of the terms and
     provisions thereof will violate any Federal or state law or regulation
     relating to its banking or trust powers or contravene or result in any
     breach of, or constitute any default under its certificate of
     incorporation, or by-laws or the provisions of any indenture, mortgage,
     contract or other agreement to which it is a party or by which it or its
     properties may be bound or affected or any judgment or order binding upon
     it;

              (iv)  each of this Agreement and the Indenture has been duly
     executed and delivered by it and, assuming that each such agreement is the
     legal, valid and binding obligation of each other party thereto, is the

     against the Indenture Trustee in accordance with its terms, subject to
     applicable bankruptcy, reorganization, insolvency, moratorium or other
     similar laws or equitable principles affecting creditors' rights generally
     from time to time in effect;

               (v)  neither the execution and delivery of this Agreement and the
     Indenture, nor the authentication of the Certificates to be delivered on
     the Refunding Date, nor the consummation by the Indenture Trustee of any of
     the transactions contemplated hereby or thereby require the Indenture
     Trustee to obtain the consent or approval of, give notice to, or register
     with, or take any other action with respect to, any state or Federal agency
     or authority governing the banking and trust powers of the Indenture

                                        -49-

 
     Trustee, in its individual capacity or as Indenture Trustee except such
     consents as have been obtained; and

              (vi)  the representations and warranties of the Original Indenture
     Trustee set forth in Section 7 of the Original Participation Agreement were
     correct on and as of the Delivery Date (except to the extent that such
     representations expressly relate solely to a specified earlier date, in
     which case such representations and warranties were correct on and as of
     such earlier date).

          (f)  The Interim Refinancing Loan Participant represents and warrants
as of the date hereof (except as otherwise provided) and as of the Refunding
Date that the representations and warranties of the Interim Refinancing Loan
Participant set forth in Section 7 of the Original Participation Agreement were
correct on and as of the "Interim Refunding Date" (as defined in the First
Amendment to Participation Agreement) (except to the extent such representations
expressly relate solely to a specified earlier date, in which case such
representations and warranties were correct on and as of such earlier date).

          (g)  The Pass Through Trustee, in its individual capacity (except for
clause (iii) hereof) represents and warrants as of the date hereof (except as
otherwise provided), as of the Pass Through Closing Date and as of the Refunding
Date that:

               (i)  it is a validly existing banking corporation duly organized
     under the laws of the State of New York and has the corporate power and
     authority to enter into and perform its obligations under the Pass Through
     Agreement, each Series Supplement and this Agreement and to execute and
     authenticate the Pass Through Certificates to be delivered on the Pass
     Through Closing Date;

              (ii)  the execution, delivery and performance of this Agreement,
     the Pass Through Agreement and each Series Supplement and the performance
     of its obligations thereunder (including the execution and authentication
     of the Pass Through Certificates to be delivered on the Pass Through
     Closing Date) have been duly authorized by all necessary corporate action
     on its part, and, subject to (A) the registration of the issuance and sale
     of the Pass Through Certificates under the Securities Act, (B) compliance
     with any applicable state securities laws and (C) the qualification of the
     Pass Through Agreement under the Trust Indenture Act, neither the execution
     and delivery thereof nor its performance of any of the terms and provisions
     thereof will (x) violate any Federal or state law or regulation relating to
     its banking or trust powers or contravene or result in any breach of, (y)
     constitute any default under its certificate of incorporation, or by-laws
     or the provisions of any

                                        -50-

 
     indenture, mortgage, contract or other agreement to which it is a party or
     by which it or its properties may be bound or affected, or (z) require the
     Pass Through Trustee to obtain the consent or approval of, give notice to,
     or register with, or take any other action with respect to, any state or
     federal agency or authority;

             (iii)  each of this Agreement and the Pass Through Agreement has
     been, and as of the Pass Through Closing Date each of the Series
     Supplements will be, duly executed and delivered by it and, assuming that
     each such agreement is the legal, valid and binding obligation of each
     other party thereto, is or will be, as the case may be, the legal, valid
     and binding obligation of the Pass Through Trustee, enforceable in
     accordance with its terms except as limited by bankruptcy, insolvency,
     moratorium, reorganization, receivership, fraudulent conveyance or other
     similar laws or equitable principles of general application to or affecting
     the enforcement of creditors' rights and remedies generally from time to
     time in effect, regardless- of whether such enforceability is considered in
     a proceeding at equity or at law;

              (iv)  the performance by the Pass Through Trustee of its
     obligations under this agreement and the Pass Through Agreement will not
     subject any part of the Trust Estate or the Indenture Estate to any Lien
     (other than the Liens created by the Lease and the Indenture) under any
     indenture, mortgage, contract or other instrument to which it is a party or
     by which it is bound; and

               (v)  there are no pending or, to the knowledge of the Pass
     Through Trustee, threatened actions or proceedings against the Pass Through
     Trustee before any court, administrative agency or tribunal which, if
     determined adversely to the Pass Through Trustee, would materially
     adversely affect the ability of the Pass Through Trustee to perform its
     obligations under any of the Operative Documents to which it is or will be
     party, and the Pass Through Trustee has no actual knowledge of any pending
     or threatened actions or proceedings before any court, administrative
     agency or tribunal involving it in its capacity as Pass Through Trustee.

          (h)  The Owner Trustee, in its individual capacity, at its own cost
and expense (and at no after-tax cost to the Indenture Trustee, the Pass Through
Trustee, the Owner Trustee, the Owner Participant, any Holder, any Pass Through
Trust, the Trust Estate, the Indenture Estate and the Lessee), covenants that it
will in its individual capacity promptly take such action as may be necessary to
discharge duly any Lessor's Liens attributable

                                        -51-

 
to it in its individual capacity and will personally hold harmless and indemnify
each Holder, the Pass Through Trustee, the Lessee, the Owner Participant, the
Indenture Trustee, the Trust Estate, the Indenture Estate, the Pass Through
Trusts and their respective successors, assigns, servants, representatives and
agents against any and all liabilities, obligations, losses, damages, penalties,
claims, actions, suits, costs, expenses and disbursements, including fees and
expenses, of whatsoever kind and nature and against any reduction in the amount
payable out of the Trust Estate, the Indenture Estate, or the Pass Through
Trusts and against any interference with the possession, operation, or other use
of the Aircraft, Airframe, any Engine or any Part, imposed on, incurred by or
asserted against any of the foregoing as a consequence of any such Lessor's
Lien. The Owner Trustee, in its trust capacity, and at the cost and expense of
the Lessee, covenants that it will, in its trust capacity, promptly take such
action as may be necessary to discharge duly any Lessor's Liens attributable to
it in its trust capacity. The Indenture Trustee, in its individual capacity, at
its own cost and expense (and at no after-tax cost to the Indenture Trustee, the
Pass Through Trustee, Owner Trustee, Owner Participant, any Holder, the Trust
Estate, the Indenture Estate, any Pass Through Trust or the Lessee), covenants
that it will in its individual capacity promptly take such action as may be
necessary to discharge duly any Indenture Trustee's Liens and will personally
hold harmless and indemnify each Holder, the Pass Through Trustee, the Lessee,
the Owner Participant, the Owner Trustee, the Trust Estate, the Indenture
Estate, the Pass Through Trusts and their respective successors, assigns,
servants, representatives and agents against any and all liabilities,
obligations, losses, damages, penalties, claims, actions, suits, costs, expenses
and disbursements, including fees and expenses, of whatsoever kind and nature
and against any reduction in the amount payable out of the Trust Estate, the
Indenture Estate, the Pass Through Trusts and against any interference with the
possession, operation, or other use of the Aircraft, Airframe, any Engine or any
Part, imposed on, incurred by or asserted against any of the foregoing as a
consequence of any such Indenture Trustee's Lien.

               (i)  The Owner Trustee covenants that it will neither incur any
indebtedness for money borrowed nor enter into any business or other activity
except as contemplated by the Operative Documents.

               (j)  If (i) all or any part of the Trust Estate becomes the
property of a debtor subject to the reorganization provisions of the Bankruptcy
Code, (ii) pursuant to such reorganization provisions, including Section 1111(b)
of the Bankruptcy Code, the Owner Participant is required, by reason of the
Owner Trustee in its individual capacity or the Owner Participant being held to
have recourse liability to the Indenture Trustee or any Holder (other than as
contemplated by the Operative Documents), directly or indirectly, to make
payment on account of any amount payable as principal, premium, interest or
other amounts on the Certificates,

                                        -52-

 
and (iii) the Indenture Trustee actually receives any Excess Amount, as defined
below, which reflects any payment by the Owner Participant on account of clause
(ii) above, then the Indenture Trustee, to the extent permitted by applicable
law, shall promptly refund to the Owner Participant such Excess Amount. The
Indenture Trustee hereby waives to the fullest extent permitted by law the
benefit of the provisions of Section 1111(b) of the Bankruptcy Code with respect
to recourse against the Owner Trustee in its individual capacity and the Owner
Participant on account of any amounts payable as principal premium, interest or
other amounts pursuant to the Certificates. For purposes of this Section 7(j),
"Excess Amount" means the amount by which such payment exceeds the amount which
would have been received by the Indenture Trustee if the Owner Trustee, in its
individual capacity, or the Owner Participant had not become subject to the
recourse liability referred to in clause (ii) above. Nothing contained in this
Section 7(j) shall prevent the Indenture Trustee from enforcing any personal
recourse obligation (and retaining the proceeds thereof) of the Owner
Participant under this Participation Agreement or the Indenture or the Trust
Agreement (and any exhibits or annexes thereto) or from retaining any amount
paid by the Owner Participant under Sections 5.01, 8.02 and 8.03 of the
Indenture. Nothing contained herein shall be construed as requiring any Holder
or holder of a Pass Through Certificate to refund any amount distributed to it
pursuant to the Indenture or the Pass Through Agreement, respectively.

          (k)  The representations and warranties set forth in this Section 7
shall survive the Closings hereunder.

          Section 8.  Other Documents.  (a) The Lessee hereby consents in all
                      ----------------
respects to the execution and delivery of the Trust Agreement and the Indenture
and to all of the terms thereof, and the Lessee acknowledges receipt of an
executed counterpart of the Trust Agreement and the Indenture; it being agreed
that such consent shall not be construed to require the Lessee's consent to any
future supplement to, or amendment, waiver or modification of the terms of, the
Trust Agreement, the Indenture, the Pass Through Certificates or the
Certificates, except that none of the provisions of Articles I and VII, Sections
2.04, 3.03, 3.05, 3.07, 3.09, 5.08, 5.09, 9.08, 9.09, 9.10, 10.06, 13.01, 13.06,
and 15.05 and Exhibit B of the Indenture shall be amended or modified without
the consent of the Lessee and except, in the case of the Trust Agreement, in
accordance with Section 11.01 of the Trust Agreement.

          (b)  The Owner Participant hereby consents in all respects to all the
terms of the Lease as entered into on the Refunding Date by the Owner Trustee
pursuant to Section 2.01 of the Trust Agreement. The Lessee hereby confirms to
the Owner Participant as of the Refunding Date its covenants set forth in and
obligations under the Lease. The Lessee agrees, for the benefit of the parties
hereto, to perform its obligations under the Pass Through Agreement.

                                        -53-

 
          (c)  Each of the Owner Participant and the Owner Trustee hereby agrees
with the Lessee and, so long as the Lien of the Indenture shall be in effect,
agrees with the Indenture Trustee and the Pass Through Trustee (i) not to
terminate or revoke the trust created by the Trust Agreement (the "Trust") or to
terminate any other Operative Document in violation of the terms thereof and
(ii) not to amend, supplement or otherwise modify any provision of (A) Article
IX or X of the Trust Agreement or (B) any other provision of the Trust Agreement
in such a manner as to adversely affect the rights of such party, without the
prior written consent of such party. Nothing in the next preceding sentence
shall impair any right under the Trust Agreement of the Owner Trustee in its
individual capacity to resign as Owner Trustee or the Owner Participant's rights
arising from Article VII of the Indenture. The provisions of Sections 5.01,
11.01, 12.01, 12.03 and 12.04 of the Trust Agreement are incorporated herein, as
if fully set forth herein.

          (d)  The Owner Trustee or any successor may resign or be removed by
the Owner Participant, a successor Owner Trustee may be appointed, and a
corporation may become the Owner Trustee under the Trust Agreement, only in
accordance with the provisions of Article X of the Trust Agreement. So long as
no Event of Default shall be continuing, no successor Owner Trustee shall be
appointed unless the Owner Participant shall in good faith have consulted with
the Lessee as to such appointment. The Owner Participant agrees to appoint as
promptly as Practicable a successor Owner Trustee if the Owner Participant shall
have knowledge that the Owner Trustee is not in compliance with its covenants
herein.

          (e)  Notwithstanding the fact that this Agreement, the Lease, the
Indenture, the Indemnity Agreement and the Trust Agreement are dated as of March
1, 1996, such documents are effective on the Refunding Date and each amend and
restate the respective original agreements with no intention of retroactive
application. Such original agreements have been restated for the convenience of
the parties and such amendments and restatements are not intended to waive or
modify the obligations or liabilities of any party which accrued or were to have
been performed on or prior to the Refunding Date under such unamended agreements
or to deprive any party of its rights and remedies in respect thereof.

          (f)  The Lessee and the Pass Through Trustee hereby agree that Section
11.08 of the Pass Through Agreement (to the extent relating to the Certificates)
shall not be amended without the prior written consent of the Owner Participant,
which consent shall not be unreasonably withheld.

          (g)  The Pass Through Trustee hereby agrees that, except as otherwise
required by applicable law (including, without limitation, any law which
requires the Pass Through Trustee to act within its own discretion), if
requested to do so by the Owner Trustee or the Owner Participant, the Pass
Through Trustee shall, at the expense of the Owner Participant, request a
direction,

                                        -54-

 
consent or waiver from the relevant Certificateholders (as defined in the Pass
Through Agreement) to determine whether action already taken by the Pass Through
Trustee should be rescinded, or action not yet taken by the Pass Through Trustee
should be taken, pursuant to the Operative Documents. The Pass Through Trustee
shall be under no obligation to request such direction, consent or waiver
pursuant to this paragraph (g) at the request of the Owner Trustee or Owner
Participant unless the Owner Trustee or the Owner Participant, as the case may
be, shall have offered to the Pass Through Trustee reasonable security or
indemnity against the costs, expenses and liabilities which might be incurred by
the Pass Through Trustee in connection with the Pass Through Trustee making such
request pursuant to this paragraph (g); provided however, that such requests of
the Owner Participant shall be at no cost to the Owner Participant if such
direction, consent or waiver is otherwise required by the Operative Documents.

          Section 9.  Benefits of Certain Obligations.  Sections 3(d) and 23 and
                      --------------------------------
the final paragraph of Section 3(a) of the Lease (as the same may be amended
from time to time in accordance with the applicable provisions of the Lease and
the Indenture) are hereby incorporated herein by reference for the express
benefit of the Indenture Trustee, the Holders and the Pass Through Trustee.
Section 15.05 of the Indenture (as the same may be amended from time to time in
accordance with the applicable provisions of the Indenture and this Agreement)
is hereby incorporated herein by reference for the express benefit of the
Lessee.

          Section 10.  Intentionally Left Blank.
                       -------------------------

          Section 11.  Liabilities of the Owner Participant and the Indenture
                       ------------------------------------------------------
Trustee.  The Owner Participant shall have no obligation or duty to the Lessee,
- ------- 
to the Original Loan Participant, to the Interim Refinancing Loan Participant,
to the Owner Trustee, to the Pass Through Trustee, to the Indenture Trustee or
to others with respect to the transactions contemplated hereby, except those
obligations or duties of the Owner Participant expressly set forth in this
Agreement and the Trust Agreement and the Owner Participant shall not be liable
for performance by any other party hereto of such other party's obligations or
duties hereunder. Without limiting the generality of the foregoing, under no
circumstances whatsoever shall the Owner Participant, as such, be liable to the
Lessee nor shall the Owner Participant be liable to any Holder, to the Original
Loan Participant, to the Interim Refinancing Loan Participant or to the Pass
Through Trustee for any action or inaction on the part of the Owner Trustee or
the Indenture Trustee in connection with the Indenture, the Trust Agreement, the
Lease, the Aircraft, the administration of the Indenture Estate or the Trust
Estate or otherwise, whether or not such action or inaction is caused by the
negligence or willful misconduct of the Owner Trustee or the Indenture Trustee,
unless, in the case of willful misconduct by the Owner Trustee, if such action
or inaction is in accordance

                                        -55-

 
with the express direction of the Owner Participant. The Indenture Trustee
agrees that (i) obligations of the Owner Trustee under the Indenture or any
other Operative Document and with respect to the Certificates shall be non-
recourse to the Owner Participant and to the Owner Trustee in its individual
capacity and (ii) it will look solely to the income and proceeds from the Trust
Estate (which does not include Excepted Payments (as defined in the Indenture))
to the extent available for distribution to the Indenture Trustee or the
relevant Holder as provided in the Indenture and that neither the Owner
Participant nor the Owner Trustee in its individual capacity shall be personally
liable to such Holder for any amounts payable by the Owner Trustee under the
Indenture or any other Operative Document. The foregoing is not intended to
limit any liability of the Owner Participant or the Owner Trustee in its
individual capacity to the extent that such liability is expressly set forth in
any of the Operative Documents.

          The Indenture Trustee is not personally liable to the Owner
Participant or any Holder for any amounts payable under the Indenture or for any
liability under the Indenture, except as provided therein.

          Section 12.  Covenants of the Lessee.  The Lessee covenants and agrees
                       ------------------------
with the Owner Participant, the Indenture Trustee, the Pass Through Trustee and
the Owner Trustee as follows (which agreements shall be performed at Lessee's
cost and expense):

          (a)  The Lessee will cause to be done, executed, acknowledged and
delivered each and every further act, conveyance and assurance as the Owner
Trustee, the Indenture Trustee, the Pass Through Trustee or the Owner
Participant shall reasonably require for accomplishing the purposes of this
Agreement, the Trust Agreement, the Indenture and the Lease. Lessee, except as
otherwise provided in Section 19 hereof and Section 7 of the Lease, at all times
will cause the Aircraft to remain duly registered under the Act in the name of
the Owner Trustee, shall promptly take such action with respect to the
recording, filing, rerecording and refiling of the Lease, the Trust Agreement
and the Indenture and the supplements thereto as is necessary to maintain the
interests and rights of the Owner Trustee in and to the Aircraft and under the
Lease and the perfection of the security interests created by the Indenture and
shall furnish to the Owner Participant or the Owner Trustee such information
(other than with respect to the citizenship of the Owner Participant and the
Owner Trustee) as may be required to enable the Owner Participant or the Owner
Trustee to make application for such registration under the Act, and shall
promptly furnish to the Owner Participant or the Owner Trustee such information
(other than with respect to the citizenship of Owner Participant and the Owner
Trustee) as may be required to enable the Owner Participant or the Owner Trustee
timely to file any reports required to be filed by it as the Lessor under the
Lease (or, in the case of the Owner Participant,

                                        -56-

 
as the beneficiary of the Trust Estate) with any governmental authority because
of the Owner Trustee's ownership of the Aircraft or the Owner Participant's
interest in the Trust Estate.

          (b)  The Lessee will cause the Lease, the Trust Agreement, the
Indenture and the Trust Indenture and Trust Agreement Supplement to be promptly
filed and recorded or filed for recording, to the extent permitted under the
Act, or required under any other applicable law. The Lessee shall provide
photocopies of file stamped copies of documents filed and recorded with the FAA
upon request of any party hereto.

          (c)  The Lessee shall at all times maintain its corporate existence
except as permitted by Section 12(d) hereof. The Lessee will do or cause to be
done all things necessary to preserve and keep in full force and effect its
rights (charter and statutory) and franchises; provided, however, that the
                                               --------  -------
Lessee shall not be required to preserve any right or franchise if the Lessee
shall reasonably determine that the loss thereof will not adversely affect the
rights of the Owner Participant or the Holders, or the Lessee's ability to
perform its obligations under the Operative Documents. The Lessee shall at all
times remain an "air carrier" within the meaning of the Act operating under a
certificate of public convenience and necessity issued pursuant to Section 401
thereof and shall at all times be otherwise certified and registered to the
extent necessary to fall within the purview of and to provide to Lessor (and to
the Indenture Trustee as assignee of Lessor's rights under the Lease) the
benefits contemplated by Section 1110 of the Bankruptcy Code or any successor
provisions thereto.

          (d)  The Lessee shall not (i) consolidate with or merge into any other
corporation under circumstances in which the Lessee is not the surviving
corporation or (ii) convey, transfer or lease substantially all of its assets as
an entirety to any Person (which term, for the purposes of this Section 12(d),
means any individual, corporation, partnership, joint venture, association,
joint-stock company, trust, unincorporated organization or government or any
agency or political subdivision thereof), unless:

               (i)  the corporation formed by such consolidation or into which
     the Lessee is merged or the Person which acquired by conveyance, transfer
     or lease substantially all of the assets of the Lessee as an entirety shall
     be a Citizen of the United States, an "air carrier" within the meaning of
     the Act operating under a certificate issued under Section 401 of the Act
     and a corporation organized and existing under the laws of the United
     States of America or any State or the District of Columbia, and shall
     execute and deliver to the Owner Trustee, the Pass Through Trustee and the
     Indenture Trustee an agreement reasonably satisfactory in form and
     substance to the Owner Trustee, the

                                        -57-

 
     Indenture Trustee, the Pass Through Trustee and the Owner Participant
     containing an effective assumption by such successor corporation of the due
     and punctual performance and observance of each covenant and condition of
     this Agreement, the Lease, the Purchase Agreement, the Purchase Agreement
     Assignment, the Indemnity Agreement and each other Operative Document to
     which the Lessee is a party to be performed or observed by the Lessee
     (which agreement shall include an undertaking to cure as promptly as
     practicable any Event of Default or Default on the date of such merger,
     consolidation, conveyance, transfer or lease, as the case may be);

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

             (iii)  the Lessee shall have delivered to the Owner Trustee, the
     Indenture Trustee, the Pass Through Trustee and the Owner Participant an
     opinion of Lessee's general counsel or other counsel satisfactory to the
     Owner Trustee, the Pass Through Trustee, the Owner Participant and the
     Indenture Trustee, and an officer's certificate, each stating that such
     consolidation, merger, conveyance, transfer or lease and the assumption
     agreement mentioned in clause (i) above comply with this Section 12(d) and
     that all conditions precedent relating to such transaction have been
     complied with and that such assumption agreement has been duly authorized,
     executed and delivered by, and constitutes a legal, valid and binding
     agreement of, such person enforceable against such person in accordance
     with its terms and that the succeeding entity is a Citizen of the United
     States and an "air carrier" within the meaning of the Act operating under a
     certificate issued under Section 401 of the Act; and

              (iv)  the corporation formed by such consolidation or into which
     the Lessee is merged or the Person which acquired by conveyance, transfer
     or lease substantially all of the assets of the Lessee as an entirety,
     shall make such filings and recordings with the FAA pursuant to the Act or
     under the laws of any other jurisdiction in which the Aircraft may then be
     registered, as shall be necessary or reasonably desirable to evidence such
     consolidation, merger, conveyance, transfer or lease with or to such entity
     in order to protect the interests of the Owner Participant, the Holders,
     the Owner Trustee and the Indenture Trustee in the Aircraft, the Trust
     Estate and the Indenture Estate.

                                        -58-

 
          Upon any consolidation or merger, or any conveyance, transfer or lease
of all or substantially all the assets of the Lessee as an entirety in
accordance with this Section 12(d), the successor corporation formed by such
consolidation or the person into which the Lessee is merged or to which such
conveyance, transfer or lease is made shall succeed to, and be substituted for,
and may exercise every right and power of, the Lessee under this Agreement with
the same effect as if such successor corporation or such person, as the case may
be, had been named as the Lessee herein. No such conveyance, transfer or lease
of all or substantially all of the assets of the Lessee as an entirety shall
have the effect of releasing the Lessee or any successor corporation which shall
theretofore have become such in the manner prescribed in this Section 12(d) from
its liability hereunder or under the Operative Documents. Nothing contained
herein shall permit any lease, sublease or other arrangement for the use,
operation or possession of the Aircraft except in compliance with the applicable
provisions of the Lease.

          (e)  The Lessee also agrees to furnish following the date of this
Agreement to the Owner Trustee, the Owner Participant, the Pass Through Trustee
and the Indenture Trustee (i) within two months after the end of the first,
second and third quarterly accounting periods in each fiscal year of the Lessee,
a consolidated balance sheet of the Lessee and its consolidated subsidiaries
prepared by it as of the close of the accounting period then ended, together
with the related consolidated statements of income, common stockholders' equity
and cash flows for the quarter then ended and reinvested earnings for such
accounting period certified by the chief accounting officer or a financial vice
president of the Lessee, (ii) within three months after the close of each fiscal
year of the Lessee, a consolidated balance sheet of the Lessee as of the close
of such fiscal year and the related consolidated statements of income, common
stockholders' equity and cash flows and reinvested earnings for the fiscal year
then ended as prepared and certified by independent certified public
accountants, including their opinion, (iii) promptly upon transmission thereof,
copies of all regular and periodic reports furnished by the Lessee to its
stockholders, (iv) promptly after filing with the SEC, copies of the Lessee's
annual reports on Form 10-K (including all corresponding annual reports to
shareholders), quarterly reports on Form 10-Q and current reports on Form 8-K,
including any amendments of such reports, (v) immediate telephonic advice after
the Lessee obtains knowledge that there exists an Event of Default, confirmed
promptly by an officer's certificate describing such default in reasonable
detail, with a statement of the Lessee's action with respect thereto taken or
proposed to be taken and (vi) from time to time such other information as the
Owner Trustee, the Pass Through Trustee, the Indenture Trustee or the Owner
Participant may reasonably request. The Lessee's obligations pursuant to clauses
(i) and (ii) of the foregoing sentence any may be satisfied by furnishing to the
Owner Trustee, the Owner Participant, the Pass Through Trustee and the Indenture
Trustee

                                        -59-

foregoing sentence.

          On or before March 31 of each calendar year commencing in 1997, the
Lessee shall deliver to the Owner Trustee and the Indenture Trustee a
certificate of the Lessee, signed by a Responsible Officer of the Lessee (and
the Lessee shall at the time furnish a copy thereof to the Owner Participant and
the Pass Through Trustee), to the effect that the signer is familiar with or has
reviewed the relevant terms of this Agreement and the Lease and has made, or
caused to be made under his supervision, a review of the transactions and
condition of the Lessee during the preceding calendar year, and that such review
has not disclosed the existence during such calendar year, nor does the signer
have knowledge of the existence as at the date of such certificate, of any
condition or event which constitutes an Event of Default, or, if any such
condition or event existed or exists, specifying the nature and period of
existence thereof and what action the Lessee has taken or is taking or proposes
to take with respect thereto.

          Section 13.  Owner for All Purposes.  It is hereby acknowledged by the
                       -----------------------
Lessee that the Owner Trustee is the owner of the Aircraft and the Lessee will
be the lessee thereof for all purposes; provided, however, that all parties
                                        --------  -------
acknowledge (but do not represent) that the Owner Participant is the owner of
the Aircraft for income tax purposes.

          Section 14.  Expenses.  (a) If the refunding contemplated to occur
                       ---------
on the Refunding Date shall be consummated, the Owner Participant shall pay
promptly all fees and expenses of the following persons relating to the public
offering of the Pass Through Certificates contemplated by the Underwriting
Agreement and related to the transactions contemplated hereby: (i) the fees and
expenses of counsel for the Owner Participant; (ii) the fees and expenses of
counsel for the Owner Trustee, the Indenture Trustee, the Pass Through Trustee,
the Interim Refinancing Loan Participant and the Underwriters (other than those
fees, expenses and disbursements payable by the Underwriters pursuant to the
Underwriting Agreement); (iii) the fees and expenses of Daugherty, Fowler &
Peregrin; (iv) any initial fees of the Owner Trustee, the Pass Through Trustee
and the Indenture Trustee; (v) any compensation, commissions and discounts
payable to the Underwriters pursuant to the Underwriting Agreement; (vi) the
fees of American Bank Note Company, if any; (vii) the fees and expenses incurred
in connection with printing any amendment to the Registration Statement on Form
S-3 bearing Registration No. 33-50175 and printing any Preliminary Prospectus or
Prospectus (as such terms are defined in the Underwriting Agreement) for the
offering of the Pass Through Certificates; (viii) the fees and expenses of
Arthur Andersen & Co.; and (ix) the fees and expenses of Moody's Investors
Service, Inc. and Standard & Poor's Corporation.

                                        -60-

 
          The Owner Participant, the Owner Trustee and the Lessee acknowledge
that the percentages for Basic Rent, Stipulated Loss Value, Termination Value
and the calculation of the EBO Percentage, set forth in the Lease, have been
prepared assuming the aggregate amount payable by the Owner Participant pursuant
to the preceding paragraph, Section 14 of the Original Participation Agreement
and Section 10 of the First Amendment to Participation Agreement is $___________
(the "Estimated Expense Amount"). If the amount of the expenses paid by the
Owner Participant is less than the Estimated Expense Amount, the Owner
Participant shall pay all costs, fees and expenses of the Owner Trustee in
connection with the administration of the Trust Estate until such time as the
amount paid by the Owner Participant pursuant to the preceding paragraph and the
costs, fees and expenses of the Owner Trustee paid by the Owner Participant
equals the Estimated Expense Amount. If the amount of the expenses is greater
than the Estimated Expense Amount, the excess shall be paid by the Lessee on
behalf of the Owner Participant as Supplemental Rent on an after-tax basis.

          Notwithstanding the provisions of the first paragraph of this Section
14(a), the Lessee agrees to pay as Supplemental Rent all reasonable costs, fees
and expenses of the Owner Participant, the Owner Trustee, the Pass Through
Trustee and the Indenture Trustee, including, without limitation, the item
enumerated in the first paragraph of this Section 14(a), if the transactions
contemplated hereby fail to close for any reason; provided, however, that if
such failure to close is solely caused by the wrongful failure of the Owner
Participant to close, after satisfaction of the conditions precedent set forth
herein to participation in the transactions contemplated hereby, the Lessee
shall have no obligation to the Owner Participant to cover the expenses incurred
by the Owner Participant (including the fees of Dewey Ballantine, special
counsel to the Owner Participant), it being understood that nothing hereunder
shall affect the Lessee's right to initiate an action at law to recover damages
from the Owner Participant with respect to all amounts paid by the Lessee
pursuant to the first paragraph of this Section 14(a).

          The Owner Participant shall pay, to the extent it has not already done
so, all amounts payable by it pursuant to Section 14(a) of the Original
Participation Agreement and Section 10 of the First Amendment to Participation
Agreement.

           (b)  The Lessee shall pay:

                (i)  subject to Section 14(a) hereof, all its own costs, fees
     and expenses in connection with the transactions contemplated hereby and by
     the Original Participation Agreement and the First Amendment to
     Participation Agreement, including, but not limited to, the fees, expenses
     and disbursements of King & Spalding, special counsel for the Lessee;

                                        -61-

 
              (ii)  subject to the second sentence of the second paragraph of
     Section 14(a), as Supplemental Rent all reasonable out-of-pocket costs,
     fees and expenses of the Owner Trustee, the Pass Through Trustee, FSC and
     of the Indenture Trustee (other than the initial fees, expenses and
     disbursements referred to in the first paragraph of Section 14(a) hereof
     and Section 14(a) (iii) of the Original Participation Agreement) in
     connection with the administration of the Indenture Estate, the Trust
     Estate, the Pass Through Trusts or the activities of FSC;

             (iii)  to the extent not already paid, as Supplemental Rent, all
     reasonable out-of-pocket costs, fees and expenses of the parties hereto (or
     their predecessors in interest) incurred in connection with the attempt in
     September/October 1994 to refund amounts payable by the Owner Trustee to
     the Original Loan Participant; and

              (iv)  as Supplemental Rent, on an after-tax basis (except that the
     Owner Participant shall not be entitled, pursuant to this Agreement, to be
     reimbursed for the tax cost of any such payment of Supplemental Rent to the
     extent provision for such reimbursement is made in the Indemnity
     Agreement), all reasonable costs, fees and expenses of the Owner
     Participant, the Owner Trustee, the Pass Through Trustee and the Indenture
     Trustee in connection with any supplements, amendments, modifications or
     consents to, or waivers of, any of the Operative Documents entered into
     after the Refunding Date, unless such supplements, amendments,
     modifications, consents or waivers are initiated by a party other than the
     Lessee and are not required or necessary to effectuate the intent of any
     provisions of the Operative Documents.

          Section 15.  Miscellaneous.  (a) This Agreement may be executed in any
                       --------------
number of counterparts, all of which taken together shall constitute one and the
same instrument, and any of the parties hereto may execute this Agreement by
signing any such counterpart. This Agreement may be terminated, amended,
supplemented, waived or modified only by an instrument in writing signed by all

Trust Agreement, assigns.

                                        -62-

required or permitted by the terms hereof or the other Operative Documents shall

All notices delivered, mailed or dispatched pursuant to this Section 15(b) shall

SHALL IN ALL RESPECTS BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS
OF THE STATE OF NEW YORK, INCLUDING ALL MATTERS OF CONSTRUCTION, VALIDITY AND
PERFORMANCE BUT WITHOUT GIVING EFFECT TO THE CONFLICT OF LAWS PROVISIONS
THEREOF.

          (d)  Each of the Owner Trustee, the Indenture Trustee and the Pass
Through Trustee is entering into this Agreement solely as trustee as provided in
the Trust Agreement, the Indenture, the Pass Through Agreement and each Series
Supplement and not in its individual capacity (except as otherwise expressly
provided herein or therein) and in no case whatsoever shall any of them be
liable in its individual capacity for any of the statements, representations,
warranties, agreements or obligations of the Owner Trustee, the Pass Through
Trustee or the Indenture Trustee, as the case may be, in its trust capacity
hereunder, or for any loss in respect thereof, as to all of which the parties
agree to look solely to the Trust Estate and the Indenture Estate; provided,
                                                                   --------
however, that (i) the Indenture Trustee in its individual capacity shall be

liable hereunder for its own gross negligence or willful misconduct or for the
inaccuracy or breach of its representations and warranties and agreements made
in its individual capacity in Sections 7(d), 7(e) and 7(h) hereof, and (ii) the

                                        -63-

 
to invest funds pursuant to Section 22 of this Agreement, Section 24 of the
Lease, or Section 3.02 of the Trust Agreement, or (e) for any liability on the
part of the Owner Trustee arising out of its negligence or willful or negligent
misconduct in connection with its obligations under Sections 6.01, 6.06 or 10.02
of the Trust Agreement or Section 3.05(b)(iii) of the Indenture. The Indenture
Trustee and the Owner Trustee, in their individual capacities, each accepts the
benefits of the indemnification granted, and the representations and warranties
made, to each of them hereunder.

          (e)  This Agreement, all other Operative Documents and all documents
relating hereto, including, without limitation, (1) consents, waivers and
modifications which may hereafter be executed and (2) financial statements,
certificates and other information previously or hereafter furnished to any
party hereto, may be reproduced by such party by any photographic, photostatic,
microfilm, micro-card, miniature photographic or other similar process, and such
party may destroy any original documents so reproduced. Any such reproduction
shall be admissible in evidence as the original itself in any judicial or
administrative proceeding (whether or not the original is in existence and
whether or not such reproduction was made by such party in the regular course of
business) and any enlargement, facsimile or further reproduction of such
reproduction shall likewise be admissible in evidence.

          (f)  The captions in this Agreement are for convenience of reference
only and shall not define or limit any of the terms or provisions hereof.

          (g)  (A) Each of the Lessee, the Owner Trustee in its individual
capacity and the Indenture Trustee in its individual capacity agrees that it
will, for purposes of Section 101(16) of the Act, immediately upon obtaining
actual knowledge of any facts which would cast doubt upon its continuing status
as a Citizen of the United States and promptly upon public disclosure of
negotiations in respect of any transaction which would or might adversely affect
such status, notify in writing all parties hereto of all relevant matters in
connection therewith.

          (B)  The Owner Participant agrees that, for purposes of Section
101(16) of the Act, in the event its status is to change as a Citizen of the
United States, or it makes public disclosure of circumstances as a result of
which it believes that such status is likely to change, it will notify in
writing all parties hereto of (i) such change in status promptly after obtaining
knowledge thereof or (ii) such belief as soon as practicable after such public
disclosure but in any event within ten Business Days after such public
disclosure.

                                        -64-

 
          (C)  If the Owner Trustee shall at any time obtain knowledge of any
facts which would cast reasonable doubt upon the continuing status of the Owner
Trustee in its individual capacity as a Citizen of the United States, it shall
immediately resign as Owner Trustee, and the Owner Participant shall as promptly
as practicable, and after consulting with the Lessee, appoint a Citizen of the
United States as successor Owner Trustee pursuant to Section 10.01 of the Trust
Agreement.

          (D)  If the Owner Participant shall, at any time while the Aircraft is
registered in the United States, cease to be a Citizen of the United States (if
and so long as such citizenship is necessary under the Act to permit the U.S.
registration of the Aircraft (it being understood that the evidence of any such
requirement shall he determined without giving consideration to any provision of
the Act (or any superseding statute) which permits United States registration of
an Aircraft based on conditions which impose restrictions on the location and
use of the Aircraft or otherwise restrict the ability of an air carrier to
operate the Aircraft in the ordinary course of its business)), the Owner
Participant shall immediately at its own expense either (X) take such action as
may be required to maintain the U.S. registration of or, in the case of
reregistration, to reregister the Aircraft and (to the extent such recordation
is dependent on the U.S. registration of the Aircraft) the recordation with the
FAA of the Indenture, Lease and any Lease Supplement (which may, if the U.S.
registration of the Aircraft is thereby maintained or reregistration is thereby
permitted, include the use of a voting trust or other similar arrangements in
which event the provisions contained herein restricting the Owner Participant's
or the Owner Trustee's ability to amend the Trust Agreement shall not apply to
the extent necessary to permit the use of such a voting trust or other similar
arrangement), or (Y) transfer, in accordance with Section 16 hereof and Article
IX of the Trust Agreement, its right, title and interest in and to the Trust
Agreement, the Trust Estate and this Agreement or (Z) take such other action as
may be necessary to prevent the Lessee or the Indenture Trustee from being
adversely affected (in the context of the transactions contemplated hereby) as a
result of such cessation of citizenship. If the Owner Participant shall fail to
comply with any of clauses (X), (Y) or (Z), then so long as such failure shall
thereafter continue the Owner Participant shall be obligated to reimburse the
Lessee for any additional costs and expenses or loss of income which the Lessee
shall thereafter actually incur with respect to the Aircraft due to such change
in citizenship of the Owner Participant (but the Lessee shall not be entitled to
receive such reimbursement so long as an Event of Default or a Payment Default
shall have occurred and be continuing or if the Owner Participant shall have
complied with any of clauses (X), (Y) or (Z) within 10 days after a Responsible
Officer of the Owner Participant has actual knowledge of the facts requiring
such actions). If the Lessee has reregistered the Aircraft outside the United
States and decides thereafter to reregister the Aircraft under the Act, the
Lessee shall notify the Owner Participant, the Owner Trustee, and

                                        -65-

 
the Indenture Trustee of its decision and the date as of which the
reregistration is proposed to be effective. If the Owner Participant shall, at
the time when the Aircraft is proposed to be reregistered under the Act, not be
a Citizen of the United States and such citizenship is necessary under the Act
to permit the registration or reregistration of the Aircraft under the Act;
without giving consideration to any provision of the Act which permits United
States registration of an aircraft based on conditions which impose restrictions
on the location and use of the Aircraft or otherwise restrict the ability of an
air carrier to operate the Aircraft in the ordinary course of its business, the
Owner Participant shall promptly, at its own expense, comply with any of clauses
(X), (Y) or (Z) of this paragraph (D) and, if it shall fail to do so, reimburse
the Lessee for any additional costs and expenses or loss of income which the
Lessee shall thereafter actually incur with respect to the Aircraft due to the
Owner Participant not being a Citizen of the United States; provided, however,
that (x) the Lessee shall not be entitled to receive such reimbursement so long
as an Event of Default or a Payment Default shall have occurred and be
continuing and (y) the Owner Participant shall not be obligated to reimburse the
Lessee pursuant to this sentence if the Owner Participant has complied with any
of clauses (X), (Y) or (Z) of this paragraph (D) within the later of (1) the
date as of which reregistration of the Aircraft is to be effective and (2) sixty
(60) days following the receipt by the Owner Participant of the Lessee's notice
of its intention to reregister the Aircraft under the Act. In each such case
described in this paragraph (D), the Lessee shall use reasonable efforts to
minimize its loss of income or damages but shall be under no obligation to
sublease the Aircraft or reregister the Aircraft in another jurisdiction.  

          (E)  The Owner Participant, the Owner Trustee and the Indenture
Trustee shall be required to give the notice and take the action specified in
paragraphs (A), (B), (C) and (D) of this Section 15(g) only if a Responsible
Officer of such Owner Participant, the Owner Trustee or the Indenture Trustee,
as the case may be, shall have actual knowledge of the facts requiring the
giving of such notice or the taking of such action.

          (h)  Anything contained in this Agreement, the Indenture, the Trust
Agreement or the Lease to the contrary notwithstanding, the Owner Participant
hereby agrees to assume liability for, and does hereby indemnify and agree to
protect, defend, save and keep harmless each Holder and its respective
successors, assigns, agents and servants, from and against any and all
liabilities, obligations, losses, damages, penalties, claims, actions, suits,
costs, expenses and disbursements (including reasonable legal fees and expenses
but excluding internal costs and expenses, including, without limitation,
overhead and salaries) to the extent caused by any impairment or claimed
impairment of the perfection or rank of the Lien of the Indenture on the
Indenture Estate or any portion thereof (except when such impairment arises from
Lessor's Liens, Indenture Trustee's Liens

                                        -66-

 
or Liens which the Lessee is required to remove under the terms of the Lease),
resulting directly and solely from the failure of the Lessee to maintain the
registration of the Aircraft under the Act when (i) the lapse of such
registration or (ii) the inability to reregister under the Act when Lessee is
requesting such registration or an Event of Default has occurred and is
continuing is solely because the Owner Participant has ceased to be a Citizen of
the United States.

          (i)  Subject to the requirements and conditions precedent of the
Operative Documents and applicable law, the parties hereto and each of the them
agree, from time to time, to execute, acknowledge and deliver such other
documents or instruments, and to do or cause to be done such other acts or
things as any other party hereto may reasonably request, that may be necessary
or desirable to effect the transactions contemplated herein (including without
limitation in connection with any refunding pursuant to Section 20 hereof, the
execution, delivery and/or provision of any appropriate additional or modified
amendment, representation, warranty, certificate, opinion or other document that
may reasonably be requested by the Lessee or any other person). The Lessee
hereby agrees to pay on an after-tax basis all reasonable fees and out-of-pocket
expenses incurred by the Owner Participant, the Owner Trustee and the Indenture
Trustee in accordance with this Section 15(i).

          Section 16.  Assignment By the Owner Participant.  (a) Prior to the
                       ------------------------------------
termination or expiration of the Lease (or, if later, until the Lien of the
Indenture is discharged), the Owner Participant will not sell, assign, transfer
or otherwise dispose of its rights (whether separately or in connection with any
transaction contemplated by the immediately following paragraph) as the Owner
Participant except in compliance with Sections 9.01 and 9.02 of the Trust
Agreement, the terms and provisions of which are incorporated herein by
reference.

          (b)  If there is a merger or consolidation of the Owner Participant
and the resulting corporation (the "New Corporation") is an airline operating
regularly scheduled commercial jet passenger or cargo transport service on
domestic United States routes or an Affiliate of such an airline and the Lessee
does not approve of the New Corporation as the Transferee of the Owner
Participant, the Lessee shall have the right (provided that it shall have given
the Owner Participant notice of its disapproval within 60 days of receiving
notice of such merger or consolidation) to require that the Owner Participant or
the New Corporation, as the case may be, transfer to Lessee as hereinafter
provided, in accordance with Article IX of the Trust Agreement all of its right,
title and interest in and to the Trust Agreement, the Trust Estate and this
Agreement. If the Owner Participant or the New Corporation does not comply with
the preceding sentence on or prior to the 180th day following the giving of
notice of the Lessee to the Owner Participant or the New Corporation of the
Lessee's disapproval of the New Corporation as the Transferee of

                                     -67-

 
the Owner Participant, the Lessee may make one of the following elections:

               (i)  The Lessee may purchase the Aircraft, and direct the Owner
Trustee to give notice of prepayment of the Certificates pursuant to Section
6.02(E) of the Indenture, for an amount equal to (a) whichever shall be the
greatest of (x) Stipulated Loss Value for the Aircraft, (y) Fair Market Value of
the Aircraft unencumbered by the Lease and (z) Fair Market Value of the Aircraft
subject to the Lease, in any such case computed as of the date of purchase in
accordance with the Lease, plus (b) the installment of Basic Rent, if any, due
on such date, if such installment is designated on Exhibit D to the Lease as
payable in arrears, plus (c) any other amounts of Basic Rent for the Aircraft
which shall be due and unpaid, plus (d) any premium payable with respect to the
Certificates pursuant to the Indenture, and (e) all other amounts, whether
Supplemental Rent or otherwise, owing by the Lessee to the Owner Trustee, the
Owner Participant, the Indenture Trustee and the Holders under any of the
Operative Documents and provided that such purchase shall be effected by the
                        --------
Lessee's payment to the Indenture Trustee of such amounts, and such monies shall
be applied by the Indenture Trustee as provided in Section 5.02 of the
Indenture; or

              (ii)  the Lessee shall have the right to purchase all of the Owner
Participant's right, title and interest in and to the Trust Agreement, the Trust
Estate and this Agreement. The purchase price for the Owner Participant's right,
title and interest in and to the Trust Agreement, the Trust Estate and this
Agreement shall be (a) whichever shall be the greatest of (x) Stipulated Loss
Value for the Aircraft, (y) Fair Market Value of the Aircraft unencumbered by
the Lease and (z) Fair Market Value of the Aircraft subject to the Lease, in any
such case computed as of the date of purchase (the "Purchase Date") in
accordance with the Lease plus (b) the installment of Basic Rent, if any, due on
such date if such installment is designated on Exhibit D of the Lease as payable
in arrears, plus (c) any other amounts of Basic Rent for the Aircraft which
shall be due and unpaid plus (d) all other amounts, whether Supplemental Rent,
or otherwise, owing by the Lessee to the Owner Participant or the Owner Trustee
under any of the Operative Documents less (e) the principal amount of the
Certificates outstanding on the Purchase Date (the "Purchase Price"). As a
condition to such purchase, the Lessee shall, on the Purchase Date, deliver to
the Indenture Trustee an opinion of counsel reasonably satisfactory to the
Indenture Trustee stating that, notwithstanding such purchase, this Agreement,
the Trust

                                        -68-

 
     Agreement and the Lease remain valid and binding obligations of the Lessee
     enforceable against the Lessee, as Lessee or as successor in interest to
     the Owner Participant, as the case may be, in accordance with their terms
     and that the Indenture and the Certificates remain valid and binding
     obligations of the parties thereto, enforceable in accordance with their
     terms and the Indenture creates a valid first priority Lien on the
     Aircraft, (or if unable to deliver such opinion, the Lessee shall effect
     amendments to the Operative Documents and the execution of such new
     agreements as shall be reasonably satisfactory to the Indenture Trustee to
     cause the indebtedness represented by the Certificates to be a direct and
     full recourse obligation of the Lessee secured by a first priority security
     interest in the Indenture Estate (as modified by such agreements and
     amendments) and the Lessee shall deliver, or shall cause to be delivered,
     such certificates, legal opinions and other documentary evidence as shall
     be reasonably requested by the Indenture Trustee as necessary or advisable
     to effect such agreements and amendments), and shall pay the Purchase Price
     to the Owner Participant in immediately available funds and shall execute
     and deliver appropriate documentation, satisfactory to the Owner
     Participant, releasing the Owner Participant from all future obligations
     and liabilities in respect of the Certificates, the Indenture and all other
     Operative Documents, to the extent that such obligations and liabilities
     arise after such transfer and do not in any way relate to events or
     circumstances occurring during the time that the Owner Participant held its
     right, title and interest in and to the Trust Agreement, the properties of
     the Owner Trustee pledged or mortgaged as part of the Indenture Estate; the
     Participation Agreement, as amended, or the Indemnity Agreement, as
     amended, for which the Owner Participant would be responsible and would not
     otherwise be indemnified by the Lessee, and the Owner Participant shall, by
     written instrument satisfactory to the Lessee and the Indenture Trustee,
     convey all of its right, title and interest to the Trust Agreement, the
     Trust Estate and this Agreement without representation or warranty, except
     as to the absence of Owner Participant's Liens. It is understood and agreed
     among the parties hereto that the transaction contemplated by this
     paragraph shall not effect a merger of the Lessee's interest, as lessee, in
     the Lease and the beneficial interest in the Trust Estate to be acquired by
     the Lessee.

          (c)  If the Lessee elects to purchase the Aircraft under Section 5(b)
of the Lease on the EBO Date, it shall elect, in its sole discretion, (A) to
direct the Owner Trustee to give notice of prepayment of the Certificates
pursuant to Section 6.02(E) of the

                                        -69-

 
Indenture or (B)(1) to effect amendments to the Operative Documents and the
execution of such new agreements as shall be reasonably satisfactory to (x) the
Indenture Trustee to cause the indebtedness represented by the Certificates to
be a direct and full recourse obligation of the Lessee secured by a first
priority security interest in the Indenture Estate (as modified by such
agreements and amendments) and (y) the Owner Participant releasing the Owner
Trustee and the Owner Participant from any and all further liability under or in
respect of the Certificates, the Indenture, the Operative Documents and any such
new agreements and (2) to deliver, or cause to be delivered, such agreements,
certificates, legal opinions and other documentary evidence as shall be
reasonably requested by the Indenture Trustee and the Owner Participant as
necessary or advisable to effect such release, agreements and amendments.

          (d)  The Lessee will pay all reasonable costs and expenses (including
reasonable attorneys' fees and disbursements) of the Indenture Trustee, the
Owner Participant, the Owner Trustee and the Pass Through Trustee in connection
with any purchase pursuant to this Section 16.

          Section 17.  Confidentiality.  No party hereto will itself
                       ----------------
intentionally disclose, directly or indirectly, any information (i) obtained
from the Lessee hereunder or in connection herewith or any portion of any
Operative Document except information filed with the FAA or SEC and available
for public inspection or (ii) obtained in connection with a proposed transfer of
the Owner Participant's interests as provided in Section 16, and will use all
reasonable efforts to have all such information kept confidential and not used
in any way known to such party to be detrimental to the Lessee, with regard to
information referred to in clause (i) above, or to the Owner Participant with
regard to information referred to in clause (ii) above; provided, that (a) each
                                                        --------
party may use, retain and disclose any such information to its financial
advisors, insurance brokers, special counsel and public accountants, any
potential transferees and any governmental agency or instrumentality or other
supervisory body requesting such disclosure, provided that such party informs
                                             --------
such financial advisors, insurance brokers, special counsel, public accountants
or potential transferees that access to such information constitutes agreement
by such person to keep such information confidential, (b) each party may use,
retain and disclose any such information which has been publicly disclosed
(other than by such party or any Affiliate thereof in breach of this Section 17)
or has rightfully come into the possession of such party or any Affiliate
thereof (other than from the Lessee, with regard to information referred to in
clause (i) above or from the Owner Participant with regard to information
referred to in clause (ii) above) and (c) to the extent that such party or any
Affiliate thereof may have received a subpoena or other written demand under
color of legal right for such information, such party or Affiliate may disclose
such information, but such party shall first, as soon as practicable

                                        -70-

 
upon receipt of such demand, furnish a copy of such demand to the Lessee, or the
Owner Participant, as the case may be, and afford the Lessee, or the Owner
Participant, as the case may be, reasonable opportunity, at the cost and expense
of the Lessee, or the Owner Participant, as the case may be, to obtain a
protective order or other reasonably satisfactory assurance of confidential
treatment for the information required to be disclosed. Nothing in this Section
17 shall prevent the Indenture Trustee from disclosing information to the
Holders in accordance with the requirements of the Indenture or prevent the Pass
Through Trustee from disclosing information to the holders of the Pass Through
Certificates in accordance with the requirements of the Pass Through Agreement
or any Series Supplement.

          Section 18.  Certain Obligations of the Owner Participant.  The Owner
                       ---------------------------------------------
Participant covenants that it will, at its own cost and expense, promptly take
such action as may be necessary to duly discharge any Owner Participant's Lien
on any part of the Trust Estate or the Indenture Estate; provided, however, that
                                                         --------  -------
the Owner Participant may in good faith by appropriate proceedings contest
claims or charges resulting in any such Lien as long as such contest does not
involve any material danger of the sale, forfeiture or loss (or loss of use of
any part of the Trust Estate or the Indenture Estate, or any interest therein
and does not involve any material danger of an interruption of the payments of
Rent assigned to the Indenture Trustee; and the Owner Participant hereby agrees
to indemnify and hold harmless the Lessee and the Holders from and against any
loss, cost, expense or damages (excluding incidental and consequential damages)
to the extent that the same may be suffered by the Lessee or any Holder as the
result of the failure of the Owner Participant to discharge and satisfy any such
Owner Participant's Lien.

          Section 19.  Change of Registration of the Aircraft.  The Owner
                       ---------------------------------------
Participant and the Indenture Trustee agree that if, at any time after the end
of the Recapture Period as long as no Event of Default has occurred and is
continuing, (i) the Lessee by at least 45 days prior written notice has
requested their consent to the registration of the Aircraft, at the Lessee's
expense, in the name of the Owner Trustee, in a country other than the United
States with which the United States at the time of such registration maintains
"normal" diplomatic relations and (ii) the Owner Participant or the Indenture
Trustee has not determined, acting reasonably, that such other country would not
provide substantially equivalent protection for the exercise of rights and
remedies of owner participants, lessors or lenders in similar transactions as
provided under United States law (except that, in the absence of restrictions
under the laws of such country on rights and remedies of lessors and secured
parties similar to those imposed by Sections 362 and 363 of the Bankruptcy Code,
rights and remedies similar to those available under Section 1110 of the
Bankruptcy Code shall not be required), then the Owner Participant and the
Indenture Trustee will not unreasonably

                                        -71-

 
withhold their consent to such change of registration (it being agreed that the
Lessee's inability to deliver an opinion (reasonably satisfactory in form and
substance to the Owner Participant and the Indenture Trustee) of counsel
acceptable to the Owner Participant and the Indenture Trustee in such proposed
country of registry as to the matters referred to in clause (ii) above and to
the effect that the courts of such country would give effect to the title,
registry and priority of the Lien under the Indenture substantially to the same
extent as provided under United States law shall constitute reasonable grounds
for a determination that such country would not provide such protection). If
said consent is given, the Owner Participant and the Indenture Trustee will
instruct the Owner Trustee to take whatever reasonable action is necessary or
appropriate, at the Lessee's cost and expense, to effectuate such change of
registration provided, however, that prior to any such change in the country of
             --------  -------
registry of the Aircraft, the Owner Participant and the Indenture Trustee shall
have received:

               (i)  assurances reasonably satisfactory to them (A) to the effect
     that the insurance provisions of the Lease would be complied with after
     giving effect to such change of registry, (B) of the payment by the Lessee
     on an after-tax basis of any expenses in connection with such change of
     registry including, without limitation, (i) the reasonable fees and
     disbursements of counsel, (ii) any filing or recordation fees, taxes or
     similar payments incurred in connection with the registration and
     deregistration of the Aircraft and the creation and perfection of the
     security interest therein in favor of the Indenture Trustee for the benefit
     of the Holders, (iii) all costs and expenses incurred in connection with
     any filings necessary to continue in the United States of America the
     perfection of the security interest in the Aircraft and the Indenture
     Estate in favor of the Indenture Trustee, and (iv) any and all other costs,
     expenses and taxes, on an after-tax basis, whether initial or continuing,
     incurred by the Owner Trustee, the Indenture Trustee as a result of the
     registration of the Aircraft, or the creation of the security interest
     therein, under the laws of the country of registry, (C) to the effect that
     the original general and tax indemnities in favor of the Owner Participant,
     the Owner Trustee, the Trust Estate, the Pass Through Trusts, the Pass
     Through Trustee, the Indenture Estate, and the Indenture Trustee under this
     Agreement, the Indenture and the Indemnity Agreement afford each such party
     substantially the same protection as provided prior to such change of
     registry, (D) as to the continued status of the Indenture as a first
     priority Lien on the Indenture Estate, (E) that such change will not result
     in the imposition of, or increase in the amount of, any tax for which the
     Lessee is not required to indemnify the Owner Participant, the Owner

                                        -72-

 
     Trustee (or any successor, assign or affiliate thereof) or the Trust Estate
     pursuant to Section 6(b) hereof, (F) that the Owner Trustee's title to the
     Aircraft will be recognized, (G) that any import or export permits
     necessary to take the Aircraft into or out of such jurisdiction and any
     exchange permits necessary to allow all Rent and other payments provided
     for under the Lease shall be in full force and effect, (H) that any value
     added tax, customs duty, tariff or similar governmental charge relating to
     the change in jurisdiction of registration of the Aircraft shall have been
     paid in full or adequately provided for by the Lessee to the satisfaction
     of the Owner Trustee, the Indenture Trustee and the Owner Participant, (I)
     that such new country of registry imposes aircraft maintenance standards
     not materially less stringent than those of the FAA, (J) that no Event of
     Default, Payment Default or Bankruptcy Default exists and that no Event of
     Default will occur or exist upon or resulting from such reregistration and
     (K) with respect to such other matters as the Owner Participant, the Owner
     Trustee or the Indenture Trustee may reasonably request; and

              (ii)  a favorable opinion of counsel reasonably satisfactory to
      the Owner Participant, the Owner Trustee and the Indenture Trustee in the
      new jurisdiction of registry (A) that the terms (including, without
      limitation, the governing-law, service-of-process and jurisdictional-
      submission provisions thereof) of the Lease and the Indenture are legal,
      valid, binding and enforceable in such jurisdiction, (B) that it is not
      necessary for the Owner Participant, the Owner Trustee, or the Indenture
      Trustee to register or qualify to do business in such jurisdiction, (C)
      that there is no tort liability of the owner of an aircraft not in
      possession thereof or of persons lending money to such an owner for the
      purchase of an aircraft, under the laws of such jurisdiction (it being
      understood that, in the event such latter opinion cannot be given in a
      form satisfactory to the Owner Participant, the Owner Trustee and the
      Indenture Trustee, such opinion shall be waived if insurance reasonably
      satisfactory to the Owner Participant, the Owner Trustee and the Indenture
      Trustee is available to cover such risk and is provided at or before the
      time of such change of registry, at the Lessee's cost and expense), (D)
      (unless the Lessee shall have agreed to provide insurance reasonably
      satisfactory to the Owner Participant and the Indenture Trustee covering
      the risk of requisition of use of or title to the Aircraft by the
      government of such jurisdiction so long as the Aircraft is registered
      under the laws of such jurisdiction) that the laws of such jurisdiction
      require fair compensation by the government of such jurisdiction payable
      in currency freely convertible into

                                        -73-

 
     United States Dollars for the loss of use of or title to the Aircraft in
     the event of the requisition by such government of such use or title, and
     (E) to such further effect with respect to such other matters as the Owner
     Participant or the Indenture Trustee may reasonably request.

          Section 20.  Refunding.  (a)  So long as no Event of Default has
                       ----------
occurred and is continuing, the Owner Participant and the Owner Trustee each
agree that (i) prepayment of the Certificates as contemplated by Section 6.02(B)
of the Indenture shall be made only with the consent of the Lessee, and (ii) to
the extent that an optional prepayment of the Certificates is permitted by the
Indenture, they will each cooperate with the Lessee to implement, in addition to
other prepayments permitted or required by this Agreement or the Lease, not more
than one refunding of the Certificates (including, without limitation, the
execution, delivery and/or provision of any appropriate additional or modified
amendment, representation, warranty, certificate, opinion or other document that
may reasonably be requested by the Lessee or any other person in connection with
such refunding and are reasonably satisfactory to, and in their judgment not
adverse to the interests of, the Owner Participant and the Owner Trustee) at
such interest rates and on such other terms as may be satisfactory to the Lessee
and at the expense of the Lessee, provided that (x) such refunding shall satisfy
                                  --------
the requirements set forth in Section 3(e) of the Lease, (y) the outstanding
principal amount of the Certificates shall not be changed in any such refunding
transaction and (z) all payments of Basic Rent and all payments relating to the
Certificates shall always be U.S. dollar denominated. Notwithstanding anything
herein to the contrary, no refunding will be permitted unless the Owner
Participant shall have received at least 3 Business Days prior written notice of
the closing date of such refunding, the Owner Participant shall have been
provided such longer period required for a reasonable opportunity to review the
relevant documentation and the Owner Participant shall have determined in good
faith that neither it nor the Owner Trustee shall suffer any loss or expense or
bear any increased risk as a result of such refunding (including, without
limitation, any risk with respect to taxes or other adverse consequences to the
Owner Participant including the application of Revenue Procedures 75-21 and 75-
28 and Section 467 of the Code (to the extent the original rent structure under
the Lease complied with Revenue Procedures 75-21 and 75-28 and Section 467 of
the Code on the Closing Date, it being understood that, to the extent that the
original rent structure complied on the Closing Date with any grandfather or
similar provisions in any regulations under Section 467 or other administrative
pronouncement interpreting Section 467, such structure shall be deemed to have
been in compliance with Section 467 on the Closing Date)) for which it has not
been or will not have been indemnified by the Lessee in a manner satisfactory in
all respects to the Owner Participant.

                                        -74-

 
          (b)  The Lessee hereby agrees to pay on an after-tax basis all
reasonable fees and out-of-pocket expenses (including without limitation,
reasonable fees and expenses of counsel) incurred by the Owner Participant, the
Owner Trustee, and the Indenture Trustee in connection with any refunding or
amendment pursuant to this Section 20.

           (c)  The Lessee agrees that neither it nor any of its Affiliates
shall at any time purchase or hold certificates issued pursuant to Section 20(a)
hereof ("Refunding Certificates") other than Refunding Certificates scheduled to
mature within the twelve month period beginning on the date of such purchase but
in no event shall the Lessee and its Affiliates hold at any one time Refunding
Certificates representing more than 5% of the Refunding Certificates then
outstanding (including such Refunding Certificates held by the Lessee and its
Affiliates). To the extent any installment of Basic Rent due is to be applied in
redemption of outstanding Refunding Certificates, maturing on a Basic Rent
payment date, the Lessee shall have the right but not the obligation to either
(i) deliver to the Indenture Trustee for cancellation, in payment of a like
amount of Basic Rent, a principal amount of Refunding Certificates not exceeding
the principal amount of Refunding Certificates maturing on such date or (ii) if
such an optional redemption is permitted under the terms of any Refunding
Certificate, have Refunding Certificates held by it in a principal amount not
exceeding the principal amount of Refunding Certificate to be redeemed on such
date redeemed in priority to all other Refunding Certificates.

          (d)  [Intentionally Omitted]

          (e)  In the case of a refunding involving a public offering of debt
securities, (1) the offering materials (including any registration statement)
for the refunding transaction shall describe the Owner Participant and the Owner
Trustee, and the terms of the transaction among the Owner Participant, the Owner
Trustee and the Lessee, only to the extent required by applicable United States
federal and state securities laws, and such offering materials shall be
otherwise reasonably acceptable to the Owner Participant and the Owner Trustee
to the extent such materials describe the Owner Participant or the Owner Trustee
or the terms of the transaction among the Owner Participant, the Owner Trustee
and the Lessee, but such offering materials shall not include any financial
information about the Owner Participant and (2) the structure of the offering
shall be reasonably satisfactory to the Owner Participant from a tax point of
view.

          (f)  No refunding pursuant to this Section 20 shall permit any
floating rate debt to be outstanding at any time after September 30, 1999.

          (g)  The Lessee, the Indenture Trustee, the Owner Trustee and the
Owner Participant each agree to execute any document necessary or advisable to
implement Section 20 of this

                                        -75-

 
Agreement (including, without limitation, the execution, delivery and/or
provision of any appropriate additional or modified amendment, representation,
warranty, certificate, opinion or other document that may reasonably be
requested by the Lessee or any other person).

          Section 21.  Compliance.  Notwithstanding any provision herein or
                       -----------
elsewhere contained to the contrary, it is understood and agreed among the
parties hereto that the transactions contemplated by this Participation
Agreement, the Lease, the Indenture and the other Operative Documents are
expressly intended to be, shall be and should be construed so as to be, entitled
to the full benefits of 11 U.S.C. Section 1110, as amended from time to time,
and any successor provision thereto.

          Section 22.  Certain Investments.  Notwithstanding any other provision
                       --------------------
of the Operative Documents, to the extent that funds are available for
investment pursuant to the Indenture or the Lease on the last Business Day of
any year, such funds shall be invested only in Permitted Investments of the
types specified in subparagraphs (a) and (b) of Section 24 of the Lease until
January 2 of the following year, at which time Section 24 of the Lease will
govern the investment of such funds. The Indenture Trustee in its individual
capacity, the Owner Trustee in its individual capacity and as Owner Trustee and
the Lessee agree to cause compliance with the foregoing instructions.

                                        -76-

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