          Section 2.01.  Participation.  Subject to all of the terms and
                         -------------
conditions of this Agreement, the parties agree to participate in the sale and
leasing transactions with respect to the Aircraft provided for in this Article
2.

          (a)  Sale and Purchase.  The Owner Trustee agrees to purchase the
               -----------------
Aircraft from the Seller on the Delivery Date for a purchase price equal to
Lessor's Cost.

          (b)  Leasing.  The Owner Trustee agrees to lease to the Lessee, and

<PAGE>

          (c)  Owner Participant's Equity Investment.  The Owner Participant
               -------------------------------------
agrees to provide immediately available funds in the amount equal to the
Lessor's Cost (the "Commitment") (i) by paying such amount to the Owner Trustee
prior to the time of closing on the Delivery Date at the account specified by
the Owner Trustee on or prior to the Delivery Date, such amount to be held and
applied toward the Owner Trustee's payment of Lessor's Cost for the Aircraft on
the Delivery Date (and if not so applied, to be promptly returned to the Owner
Participant) or (ii) by paying such amount at the time of the closing on the
Delivery Date directly to the Seller's account specified by the Lessee prior to
the closing to be applied toward the payment of Lessor's Cost. Such funds, once
so applied, shall constitute an equity investment by the Owner Participant in
the Trust Estate.

          (d)  Delivery Date.  The "Delivery Date" shall be the date fixed by
               -------------
the Lessee in accordance with this Section 2.01(d) for the closing of the sale
and leasing transactions with respect to the Aircraft contemplated hereby,
except that following such closing the "Delivery Date" shall mean the date on
which such transactions actually closed. The Lessee shall give at least two
Business Days' notice to each other party hereto of the Delivery Date, which
notice shall also specify the amount of the Commitment. The Lessee may postpone
a scheduled Delivery Date from time to time, for any reason by notice given to
the other parties hereto not later than 2:00 p.m. on the date last scheduled as
the Delivery Date, such notice to specify a new Delivery Date. In the event that
the Owner Participant shall have provided the amount of the Commitment to the
Owner Trustee prior to such a postponement, the Owner Trustee shall return such
amount to the Owner Participant by 2:00 p.m. on the scheduled Delivery Date
unless the Owner Participant shall have agreed otherwise in writing. Absent such
an agreement, in the event that the Commitment is not returned to the Owner
Participant by 2:00 p.m. on a scheduled Delivery Date on which the closing does
not occur, the Lessee shall pay interest to the Owner Participant at a rate
equal to the rate per annum announced from time to time by Citibank, N.A. as its
prime rate for each day that such commitment is not returned to the Owner
Participant by 2:00 p.m.. The making available by the Owner Participant of the
Commitment at the closing shall be deemed a waiver of notice of the Delivery
Date by the Owner Participant and the Owner Trustee.

          Section 2.02.  Closing Procedure.
                         -----------------

of the Operative Agreements to be executed, the certificates and other documents
to be delivered and the forms of the legal opinions to be delivered at the
closing by each party or its counsel pursuant to this Agreement shall be

executed, acknowledged and delivered at the Lessee's cost and expense all such
further acts, conveyances and assurances as the Owner Trustee or the Owner

the Lessee will promptly take, or cause to be taken, at the Lessee's cost and
expense, such action with respect to the recording, filing, re-recording and re-
filing of the Lease (including each supplement thereto), and any financing
statements or other instruments as may be reasonably requested by the Owner
Trustee and appropriate, to maintain the Owner Trustee's title to and interest
in the Aircraft and the Lessor's Estate, as against the Lessee and any third
parties, or if the Lessee cannot itself take, or cause to be taken, such action,
will furnish to the Owner Trustee timely notice of the necessity of such action,
together with such instruments, in execution form, and such other information as
may be required to enable either of them to take such action at the Lessee's
cost and expense in a timely manner.

          (b)  Registration.  From and after the Delivery Date, the Lessee shall
               ------------
cause the Aircraft to be duly registered, and at all times to remain duly
registered, in the name of the Owner Trustee (provided, that the Owner Trustee
                                              --------
and the Owner Participant shall be and remain Citizens of the United States),
under the Transportation Code, and shall furnish to the Owner Trustee such
information as may be required to enable the Owner Trustee to make application
for such registration; provided, however, that the Lessee may, at any time cause
                       --------  -------
the Aircraft to be appropriately re-registered under the laws of a country with
which at the time of such registration the United States maintains normal
diplomatic relations and is listed on Exhibit E to the Lease; provided that:
                                                              --------

     reasonable fees and expenses of local counsel in such country) relating to

               (iii) the Lessee shall, at its cost, cause the interest of the
     Owner Trustee as owner of the Aircraft to be duly registered or recorded
     under the laws of such country and at all times thereafter to remain so
     duly registered or recorded unless and until the registration of the
     Aircraft is changed as provided herein, and shall, at its cost, cause to be
     done at all times all other acts including the filing, recording and
     delivery of any document or instrument and the payment of any sum necessary
     or, by reference to prudent industry practice in such country, advisable in
     order to create, preserve and protect such interest in the Aircraft as
     against the Lessee or any third parties in such jurisdiction, and the laws
     of such country would give effect to the Owner Trustee's title to and
     ownership interest in the Aircraft;

                                       14
<PAGE>

               (iv)   the obligations of the Lessee (and of the Permitted
     Sublessee under a Sublease) and the rights and remedies of the Lessor and
     the Owner Participant under the Operative Agreements shall remain or be, as
     the case may be, legal, valid, binding and enforceable in such country;

               (v)    the Lessee shall ensure that all insurance required by
     Section 9 of the Lease shall be in full force and effect prior to, at the
     time of, and after such change in registration and the Owner Participant
     and the Owner Trustee shall receive a certificate of Lessee's insurance
     broker to such effect;

               (vi)   the country of such re-registration imposes aircraft
     maintenance standards approved by, or at least as stringent as those
     approved by, the FAA or the central civil aviation authority of the United
     Kingdom, France, Germany, Japan, the Netherlands or Canada and the Owner
     Trustee and Owner Participant shall receive evidence reasonably
     satisfactory to them of the same;

               (vii)  it shall not be necessary by reason of such re-
     registration or for purposes of enforcing remedies contained in the Lease
     or Sublease for the Owner Participant or Owner Trustee to register or
     qualify to do business in such country (other than in respect of
     administrative matters to be performed in the ordinary course of business
     which shall not unduly delay or frustrate Owner Trustee's or Owner
     Participant's right to exercise its remedies under any of the Operative
     Agreements);

               (viii) no Liens (except Permitted Liens) shall arise by reason of
     such re-registration;

               (ix)   none of the Owner Trustee and the Owner Participant shall
     be subjected to any risk of adverse tax consequences as a result of such
     re-registration for which the Lessee does not then indemnify or cause to be
     indemnified such Person in a manner satisfactory in form and substance to
     such Person;

               (x)    any export licenses and certificate of deregistration
     required in connection with any repossession or return of the Aircraft will
     be readily obtainable in the normal course without material delay, it being
     agreed that the Lessee shall be responsible for the cost thereof;

               (xi)   there is no tort liability of the owner or lessor of an
     aircraft not in possession thereof under the laws of such jurisdiction more
     onerous than under the laws of the United States or any state thereof (it
     being agreed that, in the event such opinion cannot be given in a form
     satisfactory to the Owner Participant, such opinion shall be waived if
     insurance reasonably satisfactory to the Owner Participant is provided to
     cover such risk);

                                       15
<PAGE>

               (xii)   unless Lessee shall have agreed to provide insurance
     reasonably satisfactory to the Owner Participant covering the risk of
     requisition of use of or title to the Aircraft by the government of such
     country (so long as the Aircraft is registered under the laws of such
     country), the laws of such country require fair compensation by the
     government of such country payable in currency freely convertible into
     Dollars and freely removable from such country (without license or permit,
     unless Lessee prior to such proposed reregistration has obtained such
     license or permit or such license or permit will be readily obtainable in
     the normal course without material delay or material burden on the Owner
     Participant) for the taking or requisition by such government of such use
     or title;

               (xiii)  the courts of such proposed country of registry will
     respect the choice of New York law to govern the Lease;

               (xiv)   such re-registration may not be affected until after the
     Recovery Period unless the Lessee prepays on a lump sum basis any liability
     due under the Tax Indemnity Agreement as a result of such re-registration;

               (xv)    if necessary, the Aircraft has been duly certified as to
     type and airworthiness by the Aeronautical Authority of such country;

               (xvi)   there exist no possessory rights in favor of the Lessee
     (or any Permitted Sublessee) which would, upon bankruptcy or insolvency of
     or other default by the Lessee, prevent the return or repossession of the
     Aircraft in accordance with and when permitted by the terms of Section
     17(a) of the Lease upon the exercise by Owner Trustee of its remedies under
     Section 17(a) of the Lease and there is no adverse effect under the laws of
     such country of re-registration to the enforceability (other than
     immaterial differences in procedures of enforcement) of the material rights
     and remedies of the Owner Trustee provided for in the Lease;

               (xvii)  the Owner Participant and the Owner Trustee shall have
     received opinions in scope, form and substance reasonably satisfactory to
     them, of counsel, expert in the laws of such country, to the effect set
     forth in clauses (iii), (iv) (with respect to the obligations of the Lessee
     under the Lease), (vii), (ix), (x), (xi), (xii), (xiii), (xv), and (xvi) of
     this Section 4.02(b);

               (xviii) such proposed change in registration is made in
     connection with a Sublease to a Permitted Air Carrier and such Permitted
     Sublessee is domiciled in such country;

               (xix)   Lessee shall deliver such request to Lessor and Owner
     Participant in writing at least 10 days in advance of the date of any such
     proposed change in registration; and

                                       16

               (xx)    the Deficiency Agreement and the Residual Agreement shall
     remain in full force and effect.

Lessee agrees to pay on an After Tax Basis all reasonable out-of-pocket costs
and expenses (including, without limitation, reasonable counsel fees and
disbursements) of the Owner Participant and the Owner Trustee in connection with
any re-registration pursuant to this Section.

        (c)  Information. The Lessee shall promptly furnish to the Owner Trustee
             -----------
and the Owner Participant such information as may be required to enable the
Owner Trustee and the Owner Participant timely to file any reports required to
be filed by the Owner Trustee as the Lessor and the Owner Participant under the
Lease with any governmental authority as a result of the Owner Trustee's
ownership interest in the Aircraft.

        (d)  Privileges and Franchises. The Lessee shall at all times maintain
             -------------------------
its corporate existence, except as permitted by Section 4.02(e) hereof and all

longer necessary or desirable in the conduct of its business.

        (e)  Merger and Consolidation.  The Lessee shall not, during the Term,
             ------------------------
enter into any merger with or into or consolidation with, or sell, convey,

or substantially all of its assets as an entirety to any Person, unless the
surviving Person which acquires by purchase, conveyance, transfer or lease all
or substantially all of the assets of the Lessee as an entirety (i) is a
domestic Person organized and existing under the laws of the United States or
any State of the United States, (ii) is a Citizen of the United States, (iii) is

with generally accepted accounting principles) at least equal to the lesser of

net worth (determined in accordance with generally accepted accounting
principles) immediately prior to such transaction; (v) if not the Lessee,
executes a duly authorized, legal, valid, binding, and enforceable agreement,
reasonably satisfactory in form and substance to Owner Trustee and Owner
Participant, containing an effective assumption of all of the Lessee's, as
applicable, obligations hereunder and under the other Operative Agreements, and
each other document contemplated hereby or thereby and delivers such instrument
to the Owner Participant and the Owner Trustee, (vi) provides an opinion from
counsel (which counsel may be the Lessee's General Counsel) delivered to the
Owner Trustee and the Owner Participant, which opinion shall be reasonably
satisfactory to the Owner Participant, and an Officer's Certificate (which may
rely, as to legal matters, on such legal opinion), each stating that such
merger, consolidation, conveyance, transfer, lease or other disposition and the
instrument noted in clause (v) above comply with this Section 4.02(e), that such
instrument is a legal, valid and binding obligation of, and is enforceable
against, such survivor or Person, and that all conditions precedent herein
provided for relating to such transaction have been complied with, and (vii)
such survivor or Person makes such filings and recordings with the FAA as may be
required pursuant to
                                       17
<PAGE>

part A of subtitle VII or Title 49, United States Code to evidence such merger
or consolidation; provided that, (x) the Deficiency Agreement and the Residual
                  -------- ----
Agreement shall remain in full force and effect and (y) no such merger,
consolidation or conveyance, transfer or lease shall be permitted if,
immediately after giving effect to such consolidation, merger, purchase,
conveyance, transfer, lease or other disposition, a Specified Default shall have
occurred and be continuing.

          Upon any consolidation or merger, or any conveyance, transfer or lease
of all or substantially all of the assets of the Lessee and the satisfaction of
the conditions specified in this Section 4.02(e), the successor corporation
formed by such consolidation or into which the Lessee is merged or the Person to
which such conveyance, transfer or lease is made shall succeed to, and be
substituted for, and must perform every obligation and may exercise every right
and power of, the Lessee under this Agreement and the Lease and each other
Operative Agreement and any other document contemplated hereby and thereby to
which the Lessee is a party with the same effect as if such successor
corporation had been named as the Lessee herein and therein.  No such
consolidation or merger, or sale, 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 the Lessee hereunder in the manner prescribed in this
Section 4.02(e) from its liability hereunder or under the other Operative
Agreements.  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.

          (f)  Change of Location. The Lessee agrees to give prompt written
               ------------------
notice (but in any event within 30 days prior to the expiration of the period of
time specified under Applicable Law to prevent lapse of perfection) to the Owner
Participant and the Owner Trustee of any change in the address of its chief
executive office (as such term is used in Section 9-103(3) of the North Carolina
Uniform Commercial Code) or of any change in its corporate name.

          (g)  Financial Statements.  The Lessee agrees to furnish to the Owner
               --------------------
Participant during the Term:

               (i)  within 60 days after the end of each of the first three
     fiscal quarters in each fiscal year of the Lessee, unaudited consolidated
     balance sheets of the Lessee and its subsidiaries (if any) as of the end of
     such quarter and related consolidated statements of income, shareholder's
     equity and cash flows of the Lessee and its subsidiaries (if any) for the
     period commencing at the end of the previous fiscal year and ending with
     the end of such quarter, provided that so long as the Lessee is subject to
                              --------
     the reporting provisions of the Securities Exchange Act of 1934, a copy of
     the Lessee's quarterly report on Form 10-Q will satisfy this requirement;

               (ii) within 120 days after the end of each fiscal year of the
     Lessee, a copy of the annual report for such year for the Lessee or the
     affiliated group of which the Lessee is a member (on a consolidated basis,
     if applicable) and a balance sheet of the Lessee and its subsidiaries (if
     any) as of the end of such fiscal year and related statements of income,

                                       18
<PAGE>

     shareholder's equity and cash flows of the Lessee for such fiscal year, in
     comparative form with the preceding fiscal year, in each case certified by
     independent certified public accountants of national standing as having
     been prepared in accordance with generally accepted accounting principles
     in the United States, provided that so long as the Lessee is subject to the
                           --------
     reporting provisions of the Securities Exchange Act of 1934, a copy of the
     Lessee's annual report on Form 10-K will satisfy this requirement; and

               (iii) from time to time, such other non-confidential financial
     information as the Lessor or the Owner Participant may reasonably request.

        (h)  Filing of Documents. Lessee, at its sole cost and expense, will
             -------------------
cause the documents filed with the FAA pursuant to Section 3.01(j), the
financing statements required pursuant to Section 3.01(k) and all continuation
statements (and any amendments necessitated by any combination, consolidation or
merger pursuant to Section 4.02(e), or any relocation of its chief executive
office) in respect of such financing statements to be prepared and, subject only
to the execution and delivery thereof by Owner Trustee, duly and timely filed
and recorded, or filed for recordation, to the extent permitted under the
Transportation Code (with respect to such documents filed with the FAA) or the
Uniform Commercial Code or similar law of any other applicable jurisdiction
(with respect to such other documents).

        Section 4.03. Survival of Representations and Warranties.  The
                      ------------------------------------------
representations and warranties of the Lessee provided in Section 4.01 and in any
other Operative Agreement shall survive the delivery of the Aircraft and the
expiration or other termination of this Agreement and the other Operative
Agreements.

     been duly executed and delivered by the Owner Participant and constitute

     laws or general equitable principles;

                     (v)   there are no pending or, to the knowledge of the

     Participant except for filings contemplated by this Agreement;

                     (vii) the funds to be used by the Owner Participant to

Agreement with respect to laws, rules or regulations relating to aviation or to
the nature or use of the equipment owned by the Owner Trustee, including,
without limitation, the airworthiness, value, condition, workmanship, design,
patent or trademark infringement, operation, merchantability or fitness for use
of the Aircraft, other than such laws, rules or regulations relating to the
citizenship requirements of the Owner Participant under applicable aviation law.

               (b)  Lessor's Liens. The Owner Participant represents, warrants
                    --------------
and covenants that on the Delivery Date there are no Lessor's Liens attributable
to it (or an Affiliate thereof). The Owner Participant agrees with and for the
benefit of the Lessee and the Owner Trustee that the Owner Participant will, at
its own cost and expense, take such action as may be necessary to duly discharge
and satisfy in full, promptly after the same first becomes known to the Owner
Participant, any Lessor's Lien attributable to the Owner Participant (or an
Affiliate thereof). The Owner Participant agrees to indemnify and hold harmless
the Lessee and the Owner Trustee from and against any loss, cost, expense
(including, without limitation, legal fees) or damage which may be suffered by
the Lessee or the Owner Trustee as a result of the failure of Owner Participant
to discharge and satisfy any Lessor's Liens attributable to it, as described in
this Section 5.01(b).

               (c)  Assignment of Interests of Owner Participant. At any time
                    --------------------------------------------
after the Delivery Date and subject to satisfaction of the conditions set forth
in this Section 5.01(c), the Owner Participant may assign, convey or otherwise
transfer to a single institutional investor or an Affiliate of an institutional
investor all (but not less than all) of the Beneficial Interest, provided that
                                                                 --------
(i) the Owner Participant gives the Lessee at least 10 days' notice of
such assignment, conveyance or other transfer, (ii) the Owner Participant and
any Owner Participant Guarantor shall remain liable for all obligations of the
Owner Participant under the Trust Agreement and the other Operative Agreements
to which the Owner Participant is a party to the extent (but only to the extent)
relating to the period on or before the date of such transfer, (iii) the
transferee agrees by a written instrument in form and substance reasonably
satisfactory to Lessee and such transferee to assume liability for, and
undertake performance of, all obligations of the Owner Participant under the
Trust Agreement and the other Operative Agreements to which such Owner
Participant is a party relating to the period after the date of transfer, (iv)
the transferee shall make a representation to the effect that the funds to be
used by the transferee to acquire the Beneficial Interest do not constitute the
assets of an ERISA Plan, (v) at or prior to the time of such transfer, the
transferee shall furnish an opinion of counsel substantially in the form
attached hereto as Exhibit B (or otherwise in form and substance reasonably
satisfactory to Lessee) (which counsel may be in-house counsel) to the effect
that such transferee and any guarantor of the payment and performance
obligations of such transferee, as the case may be, shall have requisite power
and authority and legal right to enter into and carry out the transactions

                                       21
<PAGE>

contemplated hereby; and that such agreement and any guaranty of the
transferee's obligations has been duly authorized, executed and delivered by the
transferee or the guarantor of the payment and performance obligations of such
transferee, as the case may be, and is a valid and binding agreement of the
transferee or the guarantor of the payment and performance obligations of such
transferee enforceable in accordance with its terms, subject to customary
exceptions for such opinions and that the transfer does not violate the
Applicable Law, and (vi) the Lessee shall have received an opinion from counsel
selected by Owner Participant and reasonably acceptable to Lessee that no
withholding tax will be imposed by the U.S. on Basic Rent, assuming that the
Lessee is a U.S. Person.  Any such transferee shall (a) be (i) a bank, finance
company or leasing company acting for its own account having a combined capital
and surplus (or, if applicable, consolidated net worth or its equivalent) of not
less than $50,000,000, (ii) a subsidiary of any Person described in clause (i)
where such Person provides (A) support for the obligations assumed by such
transferee subsidiary reasonably satisfactory to the Lessee and the Owner
Trustee or (B) a guaranty of such transferee subsidiary's obligations
substantially in the form attached hereto as Exhibit A (or otherwise in form and
substance reasonably satisfactory to Lessee and Owner Trustee), or (iii) an
Affiliate of the transferring Owner Participant, so long as such Affiliate has a
combined capital and surplus (or, if applicable, consolidated net worth or its
equivalent) of not less than $50,000,000 (unless the Owner Participant remains
liable for the obligations of such Affiliate under the Operative Agreements, in
which case there shall be no such net worth requirement), (b) be legally capable
of binding itself to the obligations of the Owner Participant and shall
expressly agree to assume all obligations of the Owner Participant under the
Trust Agreement and this Agreement and (c) provide representations, warranties,
and covenants substantially similar to those contained in clauses (a) and (c) of
this Section 5.01; provided that so long as no Event of Default has occurred and
                   --------
is continuing, without the prior written consent of the Lessee, such transferee
shall not be an airline or other aircraft operator or competitor of the Lessee
in the business of air transportation or an Affiliate of any thereof; and
provided further that so long as no Event of Default has occurred and is
-------- -------
continuing, neither such transferee nor any Affiliate thereof shall (x) be a
party to any material litigation or arbitration (whether as plaintiff or
defendant) with the Lessee or any Affiliate of the Lessee or (y) be attempting a
hostile takeover of the Lessee or any Affiliate of the Lessee.  A transferee
hereunder shall be a Citizen of the United States or has established a voting
trust, voting powers or other arrangement reasonably satisfactory to the Owner
Trustee and the Lessee to permit the Owner Trustee to be the registered owner of
the Aircraft under the Transportation Code, without in any way restricting the
Lessee's use and operation of the Aircraft.  The Owner Trustee shall not be on
notice of or otherwise bound by any such assignment, conveyance or transfer
unless and until it shall have received an executed counterpart of the
instrument of such assignment, conveyance or transfer.  Upon any such
disposition by the Owner Participant to a transferee as above provided, the
transferee shall be deemed the "Owner Participant" for all purposes of the
Operative Agreements, and shall be deemed to have acquired the same interest in
the Lessor's Estate as theretofore held by its transferor; and each reference
therein to the "Owner Participant" shall thereafter be deemed a reference to
such transferee and the transferring Owner Participant shall be released from
all of its obligations under the Operative Agreements to the extent such
obligations are assumed by such transferee. So long as no Event of Default has
occurred and is continuing, no assignment, conveyance or transfer by the Owner
Participant of the Beneficial Interest shall increase the amount of the
liability of the Lessee

                                       22
<PAGE>

under Article 6 hereof or under the Tax Indemnity Agreement over the amount of
liability the Lessee would have incurred had such assignment, conveyance or
transfer not occurred. The Owner Participant shall pay all costs and expenses
(including the Lessee's costs and expenses) in connection with any such
assignment, conveyance or transfer.

            (d)  Actions with Respect to Lessor's Estate, Etc.  The Owner
                 --------------------------------------------
Participant agrees that it will not take any action to subject the Lessor's
Estate or the trust established by the Trust Agreement, as debtor, to the
reorganization or liquidation provisions of the Bankruptcy Code or any other
applicable bankruptcy or insolvency statute.

            (e)  Citizenship.  The Owner Participant agrees, solely for the
                 -----------
benefit of the Lessee and the Owner Trustee, that if at any time on or after the
Delivery Date when the Aircraft is registered or the Lessee proposes to register
the Aircraft in the United States (i) either the Owner Participant shall cease
to be, or an event which has been publicly disclosed has occurred of which the
Owner Participant has knowledge and which will cause the Owner Participant to
cease to be, a Citizen of the United States, and (ii) the Aircraft shall or
would therefore become ineligible for registration in the name of the Owner
Trustee under the Transportation Code and regulations then applicable thereunder
(such eligibility to be determined without regard to any provision of law that
permits the U.S. registration of the Aircraft by restricting where it is based
or used), then the Owner Participant shall give notice thereof to the Lessee and
the Owner Trustee and shall (at its own expense and without any reimbursement or
indemnification from the Lessee) immediately (and in any event within a period
of 20 days) promptly (x) effect a voting trust or other similar arrangement, (y)
transfer in accordance with the terms of this Agreement and the Trust Agreement
all its rights, title and interest in and to such Trust Agreement, the Lessor's
Estate and this Agreement, or (z) take any other alternative action that would
prevent any deregistration, or maintain or permit the United States
registration, of the Aircraft (determined without regard to any provision of law
that permits the U.S. registration of the Aircraft by restricting where it is
based or used). If the Owner Participant fails to comply with clause (x), (y) or
(z), then the Owner Participant shall reimburse Lessee, Permitted Sublessee or
Owner Trustee for added costs and expenses or loss of income that it incurs with
respect to the Aircraft due to such change in citizenship of the Owner
Participant. Each party hereto agrees, upon the request and at the sole expense
of the Owner Participant, to cooperate with the Owner Participant in complying
with its obligations under the provisions of the first sentence of this Section
5.01(e), but without any obligation on the part of such other party to take any
action believed by it in good faith to be unreasonably burdensome to such party
or materially adverse to its business interests.

          Section 5.02.  Citizenship.
                         -----------

          (a)   Generally. The Owner Trustee, in its individual capacity,
                ---------
represents and warrants that it is and on the Delivery Date will be a Citizen of
the United States. If the Owner Trustee in its individual capacity does not
comply with the requirements of this Section 5.02, the Owner Trustee and the
Lessee hereby agree that no Default shall be deemed to exist due to non-

                                       23
<PAGE>

compliance by the Lessee with the registration requirements in the Lease or in
Section 4.02(b) hereof occasioned solely by such noncompliance of the Owner
Trustee.

          (b)   Owner Trustee.  The Owner Trustee, in its individual capacity,
                -------------
covenants that if at any time on or after the Delivery Date any of its
Responsible Officers shall have actual knowledge that it has ceased to be a
Citizen of the United States, it will resign immediately as the Owner Trustee if
such citizenship is necessary for registration of the Aircraft in the Owner
Trustee's name under the Transportation Code as in effect at such time (such
necessity to be determined without regard to any provision of law that permits
the U.S. registration of the Aircraft by restricting where it is based or used)
or, if it is not necessary for such registration, if the Owner Trustee is
informed in writing by the Lessee or any Owner Participant that such lack of
United States citizenship would have any adverse effect on the Lessee or any
Owner Participant.  The Owner Trustee, in its individual capacity, further
covenants that if at any time it appears reasonably probable that it will cease
to be a Citizen of the United States based on information that is (i) known to a
Responsible Officer of the Owner Trustee or (ii) generally known to the public,
it will promptly so notify, to the extent permitted by law, all parties to this
Agreement.

     corporate power and authority, in its individual capacity or (assuming the
     Trust Agreement has been duly authorized, executed and delivered by the

     its business as now conducted, and to execute, deliver and perform this
     Agreement and the Operative Agreements to which it is or is to be a party;

                (ii) the execution, delivery and performance by Trust Company,
     either in its individual capacity or as the Owner Trustee, as the case may

     be party have been duly authorized by all necessary corporate action on its

     with its respective terms, except as such enforceability may be limited by
     bankruptcy, insolvency, reorganization or other similar laws or equitable
     principles of general application to or affecting the enforcement of
     creditors' rights (regardless of whether enforceability is considered in a
     proceeding in equity or at law), and the performance by Trust Company in

     other party thereto, each of the Operative Agreements to which it is or is

     Participant or any successor, assign or Affiliate thereof which became
     payable by reason of any voluntary transfer or disposition by such Tax
     Indemnitee subsequent to the Delivery Date, including revocation of the

     not been a succession, assignment or other transfer by such original Tax
     Indemnitee of any such interest of such Tax Indemnitee in the Aircraft or

          Section 6.02.  After Tax Basis.  The amount which the Lessee shall be
                         ---------------
required to pay with respect to any Tax indemnified against under Section 6.01
(an "Indemnifiable Tax") shall be an amount sufficient to restore the Tax
Indemnitee, on an After Tax Basis, to the same position such party would have
been in had such Tax not been incurred, taking into account any tax benefits
recognized by such Tax Indemnitee as a result of the Indemnifiable Tax.  If any
Tax Indemnitee actually realizes a tax benefit (whether by credit, deduction or
otherwise), or would have realized such a benefit as to which it has been given
notice if properly claimed, and with respect to Owner Participant, the Owner
Participant has not determined in good faith that claiming such benefit would
have a material adverse impact on the Owner Participant or an Affiliate thereof,
by reason of the payment of any Tax paid or indemnified against by the Lessee,
provided that an Event of Default has not occurred and is not continuing, such
Tax Indemnitee shall promptly pay to the Lessee, to the extent such tax benefit
was not previously taken into account in computing such payment or indemnity,
but not before the Lessee shall have made all payments then due to such Tax
Indemnitee under this Agreement, the Tax Indemnity Agreement and any other
Operative Agreement, an amount equal to the lesser of (x) the sum of such tax
benefit plus any other tax benefit realized by such Tax Indemnitee that would
not have been realized but for any payment made by such Tax Indemnitee pursuant
to this sentence and not already paid to the Lessee, or (y) the amount of the
payment made under Section 6.01 hereof and this Section 6.02 by the Lessee to
such Tax Indemnitee plus the amount of any other payments by the Lessee to such
Tax Indemnitee theretofore required to be made under this Section 6.02 and
Sections 6.01 and 6.05 hereof (and the excess, if any, of the tax benefit over
the applicable amount described in clause (x) over the amount described in
clause (y) above shall be carried forward and applied to reduce pro tanto any
                                                                --- -----
subsequent obligations of the Lessee to make payments to such Tax Indemnitee
pursuant to Section 6.01 hereof).  If an amount payable by any Tax Indemnitee to
the Lessee pursuant to this Section 6.02 is not paid when due because of the
occurrence and continuation of any Event of Default, such amount shall be
payable by any Tax Indemnitee to the Lessee upon the Lessee's curing all Events
of Default.  The Lessee shall reimburse

                                       31
<PAGE>

on an After Tax Basis such Tax Indemnitee (subject to Section 6.01(b), but only
insofar as subsections (iv), (vi), (vii), (x), (xi), (xii), (xiii), (xiv) and
(xv) thereof would apply) for any payment of a tax benefit pursuant to the
preceding sentence (or a tax benefit otherwise taken into account in calculating
the Lessee's indemnity obligation hereunder) to the extent that such tax benefit
is subsequently disallowed or reduced.

          In determining the order in which any Tax Indemnitee utilizes
withholding or other foreign taxes as a credit against such Tax Indemnitee's
United States income taxes, such Tax Indemnitee shall be deemed to utilize (i)
first, all foreign taxes other than those described in clause (ii) below; and
(ii) then, on a pro rata basis, all foreign taxes with respect to which such Tax
Indemnitee is entitled to obtain indemnification pursuant to an indemnification
provision contained in any lease, loan agreement, or other financing document
(including this Agreement) that is similar to the indemnification provision in
this Article 6.

          Section 6.03.  Time of Payment.  Any amount payable to a Tax
                         ---------------
Indemnitee pursuant to this Article 6 shall be paid promptly, but in any event
within 30 days after receipt of a written demand therefor from such Tax
Indemnitee accompanied by a written statement describing in reasonable detail
the basis for such indemnity and the computation of the amount so payable,
provided that in the case of amounts which are being contested by the Lessee in
--------
good faith or by the Tax Indemnitee in either case pursuant to Section 6.04
hereof, or subject to verification proceedings pursuant to Section 6.11 hereof,
such amount shall be payable within 30 days after the time such contest or
verification proceeding, as the case may be, is finally resolved. In no event
shall any amount be payable under Section 6.01 until five Business Days prior to
the due date for Tax in issue.

          Section 6.04.  Contests.
                         --------

          (a)  Notice of Claim.  If a written claim is made against any Tax
               ---------------
Indemnitee for Taxes with respect to which the Lessee is liable for a payment or
indemnity hereunder, such Tax Indemnitee shall promptly (but in any event within
15 days of receipt thereof) give the Lessee notice in writing of such claim and
shall furnish the Lessee with copies of any written requests for information
sent to such Tax Indemnitee from any taxing authority to the extent relating to
such Taxes with respect to which the Lessee may be required to indemnify
hereunder; provided, however, that the failure of a Tax Indemnitee to give such
           --------  -------
notice or furnish such copy shall not terminate any of the rights of such Tax
Indemnitee under this Article 6, except (A) to the extent that the Lessee's
contest rights have been materially and adversely impaired by the failure to
provide such notice or copy or (B) to the extent that such failure results in
the imposition of, or an increase in the amount of, any penalties, interest or
additions to Tax related to the Tax which is the subject of such claim or
proceeding.

          (b)  Request for Contest.  If a written claim shall be made for any
               -------------------
Tax, for which the Lessee may be obligated to indemnify pursuant to Section 6.01
hereunder, and under applicable law of the taxing jurisdiction the Lessee is
allowed to contest directly such Tax and the Tax to be contested is not
reflected in a report or return with other Taxes of any Tax Indemnitee, then the

                                       32
<PAGE>

Lessee shall be permitted, at its expense and in its own name, or in the name of
such Tax Indemnitee, to contest the imposition of such Tax; provided, however,
                                                            --------  -------
that the Lessee shall not be permitted or entitled to contest any Tax unless (A)
such contest will not result in the risk of an imposition of criminal penalties,
(B) the Lessee shall have agreed to pay such Tax Indemnitee on demand and on an
After Tax Basis all costs and expenses that such Tax Indemnitee actually incurs
in connection with contesting such claim (including, without limitation, all
costs, expenses, losses, reasonable legal and accounting fees, disbursements, or
penalties, interest and addition to tax), (C) if such contest shall be conducted
in a manner requiring the payment of the claim in advance, the Lessee shall have
advanced sufficient funds, on an interest free basis, to make the payment
required, and agreed to indemnify the Tax Indemnitee against any additional net
adverse tax consequences on an After Tax Basis to such Tax Indemnitee of such
advance, and (D) if such contest shall be conducted in a manner requiring the
payment of the claim, the Lessee shall have paid the amount required.

          If the Lessee shall so request within 30 days after receipt of such
notice from a Tax Indemnitee under this Section 6.04 hereof and with respect to
a Tax for which the Lessee may be obligated to indemnify pursuant to Section
6.01, such Tax Indemnitee shall in good faith at the Lessee's after-tax expense
contest the imposition of such Tax.

          If requested by the Lessee, the Tax Indemnitee shall appeal any
adverse administrative or judicial decision, except that the Tax Indemnitee
shall not be required to pursue any appeals to the United States Supreme Court.

          If the taxing jurisdiction requires payment of the claim in advance of
contest, such Tax Indemnitee may make a timely request upon Lessee and Lessee
shall advance to such Tax Indemnitee on an interest-free basis the amount of
such Tax (including such amounts payable as interest, penalties or additions to
tax) and shall indemnify the Tax Indemnitee on an After Tax Basis against any
additional net cost to such Tax Indemnitee with respect to such advance.

Default is continuing (unless the Lessee has bonded or otherwise provided to the
Tax Indemnitee collateral in respect of the Tax subject to such contest, such
bond or collateral to be reasonably satisfactory to such Tax Indemnitee in form
and substance), if, after the Lessee has properly requested a contest in
accordance with this Section 6.04 and Lessee is then complying with the terms of
this Section 6.04, any Tax Indemnitee shall at any time decline to take any
action required under Section 6.04 with respect to such contest, then, if such
failure shall cause the contest to be determined adversely or shall preclude
such contest as a matter of law, the Lessee shall not be obligated to indemnify
such Tax Indemnitee for such Tax (including such amount payable as interest,
penalties or addition to tax) and such Tax Indemnitee shall reimburse the Lessee
for all amounts previously advanced by the Lessee in connection with such
contest (other than costs and expenses of such contest).

               (ii)  Provided no Event of Default is continuing (unless the
     Lessee has bonded or otherwise provided to the Tax Indemnitee collateral in
     respect of the Tax subject to such contest, such bond or collateral to be
     reasonably satisfactory to such Tax Indemnitee

                                       33
<PAGE>

     in form and substance), no Tax Indemnitee shall settle a contest of any
     indemnified Tax without requesting the Lessee's written consent (which
     consent will not be unreasonably withheld, as determined in the Lessee's
     good faith judgment). If any Tax Indemnitee shall settle a contest for any
     Tax without receiving the Lessee's written consent other than if an Event
     of Default is continuing (unless the Lessee has bonded or otherwise
     provided to the Tax Indemnitee collateral in respect of the Tax subject to
     such contest, such bond or collateral to be reasonably satisfactory to such
     Tax Indemnitee in form and substance), then the Lessee shall not be
     obligated to indemnify such Tax Indemnitee for such Tax (including such
     amount payable as interest, penalties or addition to tax) and the Tax
     Indemnitee shall reimburse the Lessee for all amounts previously advanced
     with respect to such contest. Notwithstanding the preceding two sentences,
     no Tax Indemnitee shall be required to take or continue any action unless
     the Lessee shall have agreed to pay the Tax Indemnitee on a current and
     After Tax Basis all reasonable fees and expenses (including reasonable
     attorney's and accountant's fees) which such Tax Indemnitee may incur as a
     result of contesting such Taxes.

          (d)  Claims Barred.  If (A) any Tax Indemnitee fails to give the
               -------------
Lessee written notice pursuant to this Section 6.04 of any claim by any
government or taxing authority for any Tax for which the Lessee is obligated
pursuant to this Section 6.01, (B) as a direct result of such failure the
contest of such claim becomes barred by law and (C) the Lessee furnishes, at the
Lessee's expense, an opinion of counsel selected by the Lessee and reasonably
satisfactory to such Tax Indemnitee to the effect that, had the contest of such
claim not become barred by law, a Reasonable Basis, would have existed for
pursuing such contest, such Tax Indemnitee shall be deemed to have waived its
right to any payment by the Lessee that would otherwise be payable by the Lessee
pursuant to this Section 6.01 in respect of such claim.

          Section 6.05.  Refunds.  When a Tax Indemnitee becomes entitled to
                         -------
receive a refund or credit against Tax of all or any part of any Taxes which the
Lessee shall have paid for such Tax Indemnitee or for which the Lessee shall
have reimbursed or indemnified such Tax Indemnitee, such Tax Indemnitee shall
pay, provided an Event of Default has not occurred and is not continuing, to the
Lessee an amount equal to the amount of such refund or credit less (x) all
payments then due to such Tax Indemnitee under this Article 6, and (y) Taxes
imposed with respect to the accrual or receipt thereof, including interest
received attributable thereto, plus any tax benefit realized by such Tax
Indemnitee as a result of any payment by such Tax Indemnitee made pursuant to
this sentence; provided, however, that such amount shall not be payable (a)
               --------  -------
before such time as the Lessee shall have made all payments or indemnities then
due and payable to such Tax Indemnitee under this Article 6 and (b) to the
extent that the amount of such payment would exceed (i) the amount of all prior
payments by the Lessee to such Tax Indemnitee pursuant to this Article 6 less
(ii) the amount of all prior payments by such Tax Indemnitee to the Lessee
pursuant to this Article 6 (any such excess shall be carried forward to reduce

pro tanto any subsequent obligations of the Lessee to make payments to such Tax
--- -----
Indemnitee pursuant to Section 6.01 hereof).  If an amount payable by any Tax
Indemnitee to the Lessee pursuant to this Section 6.02 is not paid when due
because of the

                                       34
<PAGE>

occurrence and continuation of an Event of Default, such amount shall be payable
by any Tax Indemnitee to the Lessee upon the Lessee's curing all Events of
Default.

          Any subsequent loss of such refund or tax benefit shall be treated as
a Tax subject to indemnification under the provisions of this Article 6 (in the
case of any such tax benefit, subject to Section 6.01(b) but only insofar as
subsections (iv), (vi), (vii), (x), (xi), (xii), (xiii), (xiv) and (xv) thereof
would apply).

          Section 6.06. Reports.  In case any report or return is required to be
                        -------
made with respect to any Taxes against which the Lessee is or may be obligated
to indemnify the Indemnitees under this Article 6, the Lessee shall, to the
extent it has knowledge thereof, make such report or return, except for any such
report or return that the Tax Indemnitee has notified the Lessee that it intends
to file, in such manner as will show the ownership of the Aircraft in the Owner
Trustee and shall send a copy of the applicable portions of such report or
return to the Tax Indemnitee and the Owner Trustee or will notify the Tax
Indemnitee of such requirement and make such report or return in such manner as
shall be satisfactory to such Tax Indemnitee and the Owner Trustee. The Lessee
will provide such information within the possession or control of the Lessee as
the Tax Indemnitee may reasonably request in writing from the Lessee to enable
the Tax Indemnitee to fulfill its tax filing requirements with respect to the
transactions contemplated by the Operative Agreements (without duplication of
any comparable requirements of the Tax Indemnity Agreement) and any audit
information request arising from any such filing. The Tax Indemnitee will
provide such information within its possession or control as the Lessee may
reasonably require from such Tax Indemnitee to enable the Lessee to fulfill its
tax filing requirements with respect to the transactions contemplated by the
Operative Agreements and any audit information request arising from such filing;
provided that in no event shall any Tax Indemnitee be required to provide copies
--------
of any of its tax returns.

          Section 6.07.  Survival of Obligations.  The representations,
                         -----------------------
warranties, indemnities and agreements of the Lessee provided for in this
Article 6 and the Lessee's obligations under any and all of them, in each case,
with respect to events or periods prior to the expiration or termination of the
Lease shall survive the expiration or other termination of the Operative
Agreements.

          Section 6.08.  Payment of Taxes.  With respect to any Tax otherwise
                         ----------------
indemnifiable hereunder by the Lessee and applicable to the Aircraft, Airframe,
any Engine or Parts, to the extent permitted by the applicable federal, state,
local or foreign law, the Lessee shall pay such tax directly to the relevant
Taxing authority and file any returns or reports required with respect thereto
to the extent legally entitled to do so in its own name; provided, however, that
                                                         --------  -------
the Lessee shall not make any statements or take any action which would indicate
that the Lessee or any Person other than the Owner Trustee or Owner Participant
is the owner of the Aircraft, the Airframe, any Engine or any Part or which
would otherwise be inconsistent with the terms of the Lease or the Tax Indemnity
Agreement and the position thereunder of the Owner Trustee and the Owner
Participant.

          Section 6.09.  Reimbursements by Indemnitees Generally.  To the extent
                         ---------------------------------------
the Lessee is required to pay or withhold any Tax imposed on or with respect to
a Tax Indemnitee in respect of the transactions contemplated by the Operative
Agreements, which Tax is not otherwise the responsibility of the Lessee under
the Operative Agreements, or any other written agreements between the Lessee and
such Tax Indemnitee, then such Tax Indemnitee shall pay to the Lessee within 30
days of the Lessee's demand therefor an amount which equals the amount actually
paid by the Lessee with respect to such Taxes.

          Section 6.10.  Forms.  Each Tax Indemnitee agrees to furnish from time
                         -----
to time to Lessee or to such other person as Lessee may designate, at Lessee's
request, such duly executed and properly completed forms as may be necessary or
appropriate in order to claim any reduction of or exemption from any withholding
or other Tax imposed by any taxing authority, if (x) such reduction or exemption
is available to such Tax Indemnitee, and (y) Lessee has provided such Tax
Indemnitee with any information necessary to complete such form not otherwise
reasonably available to such Tax Indemnitee.

          Section 6.11.  Verification.  At the Lessee's request, the accuracy of
                         ------------
any calculation of amount(s) payable pursuant to this Article 6 shall be
verified by independent public accountants selected by the applicable Tax
Indemnitee and reasonably satisfactory to the Lessee, and such verification
shall bind the applicable Tax Indemnitee and the Lessee. In order, and to the
extent necessary, to enable such independent accountants to verify such amounts,
such Tax Indemnitee shall provide to such independent accountants (for their
confidential use and not to be disclosed to the Lessee or any other person) all
information reasonably necessary for such verification. Verification shall be at
the expense of the Lessee, unless such verification results in an adjustment in
the Lessee's favor of $10,000 or more of the amount of the payment as computed
by such Tax Indemnitee, in which case the verification shall be at the expense
of the Tax Indemnitee.

          Section 6.12.  Non-Parties.  If a Tax Indemnitee is not a party to
                         -----------
this Agreement, Lessee may require the Tax Indemnitee to agree in writing, in a
form reasonably acceptable to Lessee, to the terms of this Article 6 prior to
making any payment to such Tax Indemnitee hereunder.

                                  ARTICLE 7.
                               GENERAL INDEMNITY

          Section 7.01.  Generally.
                         ---------

          (a)  Indemnity.  The Lessee agrees to indemnify each Indemnitee
               ---------
against and agrees to protect, defend, save and keep harmless each Indemnitee
from and against and in respect of, and will pay on an After Tax Basis, any and
all liabilities, obligations, losses, damages, settlements, penalties, claims,
actions, suits, costs, disbursements and expenses, demands or judgments
(including reasonable legal fees and expenses) of every kind and nature, whether
or not any of the transactions contemplated by this Agreement are consummated
and whether arising

                                       36
<PAGE>

before, on or after the Delivery Date (individually, an "Expense," collectively,
"Expenses"), which may be imposed on, incurred or suffered by or asserted
against any Indemnitee, in any way relating to, arising out of or in connection
with, any one or more of the following:

               (i)   the Aircraft or any Operative Agreement or any transaction
     contemplated thereby;

               (ii)  the operation, possession, use, non-use, maintenance,
     storage, overhaul, delivery, non-delivery, control, condition, alteration,
     modification, addition, improvement, airworthiness, replacement,
     substitution, return, abandonment, redelivery or other disposition, repair
     or testing of the Aircraft, Airframe, or any Engine or any engine used in
     connection with the Airframe, or any Part thereof by the Lessee, any
     sublessee or any other Person whatsoever, whether or not such operation,
     possession, use, non-use, maintenance, storage, overhaul, delivery, non-
     delivery, control, condition, alteration, modification, addition,
     improvement, airworthiness, replacement, substitution, return, abandonment,
     redelivery or other disposition, repair or testing is in compliance with
     the terms of the Lease, including, without limitation, claims for death,
     personal injury or property damage or other loss or harm to any Person
     whatsoever, including, without limitation, any passengers, shippers or
     other Persons wherever located, claims or penalty relating to any laws,
     rules or regulations, including, without limitation, environmental control,
     noise and pollution laws, rules or regulation and any Liens in respect of
     the Aircraft, any Engine or any Part;

               (iii) the manufacture, design, sale, return, purchase,
     acceptance, nonacceptance, rejection, delivery, non-delivery, condition,
     repair, modification, servicing, rebuilding, airworthiness, registration,
     reregistration, deregistration, ownership, financing, import, export,
     performance, non-performance, lease, sublease, transfer, merchantability,
     fitness for use, alteration, substitution or replacement of any Airframe,
     Engine, or Part or other transfer of use or possession, or other
     disposition of the Aircraft, the Airframe, any Engine or any Part
     including, without limitation, latent and other defects, whether or not
     discoverable, tort liability, whether or not arising out of the negligence
     of any Indemnitee (whether active, passive or imputed and including strict
     liability without fault), and any claims for patent, trademark or copyright
     infringement;

               (iv)  any breach of or failure to perform or observe, or any
     other non-compliance with, any condition, covenant or agreement to be
     performed, or other obligations of the Lessee under any of the Operative
     Agreements, or the falsity or inaccuracy of any representation or warranty
     of the Lessee in any of the Operative Agreements (other than
     representations and warranties in the Tax Indemnity Agreement) or the
     occurrence of any Default or Event of Default;

               (v)   the enforcement of the terms of the Operative Agreements
     (including this Section 7.01(a)); and

                                       37
<PAGE>

               (vi)  interest in the Lessor's Estate or the Trust Agreement or
     any similar interest.

          (b)  Exceptions.  The indemnity provided for in Section 7.01(a) shall
               ----------
not extend to any Expense of any Indemnitee to the extent it:

               (i)   is attributable to the willful misconduct or gross
     negligence of such Indemnitee (other than gross negligence or willful
     misconduct imputed to such person by reason of its interest in the Aircraft
     or any transaction documents);

               (ii)  except to the extent fairly attributable to acts or events
     occurring prior thereto, is attributable to acts or events (other than the
     performance by Lessee of its obligations pursuant to the terms of the
     Operative Agreements) which occur after the Aircraft is no longer part of
     the Lessor's Estate or, if the Aircraft remains a part of the Lessor's
     Estate, after the expiration of the Term (unless the Aircraft is being
     returned at such time, in which case after return of physical possession;
     provided that if the Lease has been terminated pursuant to Section 17
     --------
     thereof, the indemnity provided in Section 7.01(a) hereof shall survive for
     so long as Lessor shall be exercising remedies under such Section 17), or
     to acts or events which occur after return of possession of the Aircraft by
     the Lessee in accordance with the provisions of the Lease (subject to the
     foregoing proviso if the Lessor has terminated the Lease pursuant to
     Section 17 of the Lease);

               (iii) other than as expressly provided herein or in the other
     Operative Agreements, is a Tax or loss of a Tax benefit, whether or not the
     Lessee is required to indemnify therefor pursuant to Article 6 hereof or
     pursuant to the Tax Indemnity Agreement;

               (iv)  is a cost or expense expressly required to be paid by such
     Indemnitee or its permitted transferees (and not by the Lessee) pursuant to
     this Agreement or any other Operative Agreement and for which the Lessee is
     not otherwise obligated to reimburse such Indemnitee, directly or
     indirectly pursuant to the terms of this Agreement or such other Operative
     Agreement;

               (v)   is attributable to the incorrectness or breach by such
     Indemnitee of its representations or warranties, under any of the Operative
     Agreements;

               (vi)  is attributable to the failure by such Indemnitee to
     perform any of its obligations under any of the Operative Agreements except
     to the extent such failure was caused by a breach by Lessee of any
     representation or warranty or by any failure of Lessee to perform any
     obligation under an Operative Agreement;

               (vii) is, in the case of the Owner Participant, Lessor's Liens
     attributable to the Owner Participant; in the case of the Owner Trustee,
     Lessor's Liens to the extent

                                       38
<PAGE>

     attributable to the Owner Trustee; in the case of Trust Company, Lessor's
     Liens to the extent attributable to Trust Company;

               (viii) is, in the case of the Owner Participant or the Owner
     Trustee, attributable to the offer or sale by such Indemnitee of any
     interest in the Aircraft, the Lessor's Estate or the Trust Agreement or any
     similar interest (including an offer or sale resulting from bankruptcy or
     other proceedings for the relief of debtors in which such Indemnitee is the
     debtor), unless in each case such offer or sale shall occur pursuant to the
     exercise of remedies under Section 17 of the Lease;

               (ix)   in the case of the Owner Participant, any Taxes relating
     to, resulting from, arising out of or in connection with a "prohibited
     transaction" within the meaning of Section 406 of ERISA or Section
     4975(c)(1) of the Code;

               (x)    is attributable to any amendment to any of the Operative
     Agreements which is not requested, or consented to, by the Lessee or is not
     required or made pursuant to the terms of any of the Operative Agreements;
     and

               (xi)   constitutes the loss of future profits of such Indemnitee
     or losses attributable to such Indemnitee's overhead.

          (c)  Non-Parties.  If an Indemnitee is not a party to this Agreement,
               -----------
Lessee may require such Indemnitee to agree in writing, in a form reasonably
acceptable to Lessee, to the terms of this Article 7 prior to making any payment
to such Indemnitee under this Article 7.

          Section 7.02.  Notice and Payment.  Each Indemnitee shall give prompt
                         ------------------
written notice to the Lessee of any liability as to which a Responsible Officer
of such Indemnitee has actual knowledge, for which the Lessee is, or may be,
liable under this Article 7; provided, however, that failure to give such notice
                             --------  -------
shall not terminate any of the rights of an Indemnitee under this Article 7 and
shall not release Lessee from any of its obligations to indemnify such
Indemnitee hereunder, except to the extent that such failure adversely affects
any applicable defense or counterclaim, otherwise increases the amount the
Lessee would have been liable for in the absence of such failure to provide such
notice or adversely affects the ability of Lessee's insurers to defend such
claim.

          Section 7.03.  Defense of Claims.  The Lessee or its insurers shall
                         -----------------
have the right (in each such case at the Lessee's sole expense) to investigate,
defend (and control the defense of) any such claim for which indemnification is
sought pursuant to this Article 7 and each Indemnitee shall cooperate with the
Lessee or its insurers with respect thereto, provided that, without limiting the
                                             -------- ----
right of the Lessee's insurers to assume and control the defense of or to
compromise, any such claim, the Lessee shall not be entitled to assume and
control the defense of or compromise any such claim (A) during the continuance
of any Specified Default, (B) if an actual or potential material conflict of
interest exists making it advisable in the good faith opinion of such Indemnitee
(on the basis of prevailing standards of professional responsibility) for such
Indemnitee to be represented by separate

                                       39
<PAGE>

counsel or if such proceeding involves the potential imposition of criminal
liability on such Indemnitee or (C) if such proceeding will involve any non-de
minimis risk of the sale, forfeiture or loss of, or the creation of any Lien
(other than Permitted Liens) on the Aircraft or the Trust Estate (unless the
Lessee posts a bond or other security reasonably acceptable in form and
substance to such Indemnitee) or involve any risk of criminal liability to such
Indemnitee. Subject to the immediately foregoing sentence, where the Lessee or
the insurers under a policy of insurance maintained by the Lessee undertake the
defense of an Indemnitee with respect to such a claim, no additional legal fees
or expenses of such Indemnitee in connection with the defense of such claim
shall be indemnified hereunder unless the fees or expenses were incurred at the
written request of the Lessee or such insurers. Subject to the requirement of
any policy of insurance applicable to a claim, an Indemnitee may participate at
its own expense at any judicial proceeding controlled by the Lessee or its
insurers pursuant to the preceding provisions, to the extent that such party's
participation does not, in the reasonable opinion of the independent counsel
appointed by the Lessee or its insurers to conduct such proceedings, interfere
with the defense of such claim; and such participation shall not constitute a
waiver of the indemnification provided in this Section 7.03. No Indemnitee shall
enter into any settlement or other compromise with respect to any claim
described in this Section 7.03 without the prior written consent of the Lessee,
unless such Indemnitee waives its right to be indemnified under this Article 7
with respect to such claim. The Lessee shall not enter into any settlement or
compromise with respect to which the Lessee has not agreed to indemnify such
Indemnitee to such Indemnitee's satisfaction or which admits any criminal
violation, gross negligence or willful misconduct on the part of any Indemnitee
without the prior written consent of such Indemnitee.

          Section 7.04.  Insured Claims.  Notwithstanding any other provision of
                         --------------
this Article 7 to the contrary, in the case of any Expense indemnified by the
Lessee hereunder which is covered by a policy of insurance maintained by the
Lessee (or a Permitted Sublessee) pursuant to Section 9 of the Lease or
otherwise, it shall be a condition of such indemnity with respect to any
particular Indemnitee that such Indemnitee shall reasonably cooperate with the
insurers in the exercise of their rights to investigate, defend or compromise
such claim as may be required to retain the benefits of such insurance with
respect to such claim.

          Section 7.05.  Subrogation.  To the extent that an Expense indemnified
                         -----------
by the Lessee under this Article 7 is in fact paid in full by the Lessee and/or
an insurer under a policy of insurance maintained by the Lessee, the Lessee
and/or such insurer as the case may be shall be subrogated to the extent of such
payment to the rights and remedies of the Indemnitee on whose behalf such
Expense was paid with respect to the transaction or event giving rise to such
Expense (other than the rights and remedies in respect of insurance policies
maintained by such Indemnitee and other than the rights of the Trust Company or
the Owner Trustee and remedies against the Owner Participant under the Trust
Agreement). Should an Indemnitee receive any refund, in whole or in part, with
respect to any Expense paid in full by the Lessee hereunder, it shall promptly
pay over the amount refunded (but not an amount in excess of the amount Lessee
and/or such insurer has paid to such Indemnitee in respect of such Expense) to
the Lessee.

<PAGE>

          Section 7.06.  Information.  Subject to Section 7.04, Lessee will
                         -----------
provide the relevant Indemnitee with such information, not within the control of
such Indemnitee, as is in Lessee's control or is reasonably available to 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 Section 7.03 and to control or participate in any proceeding to the extent
permitted by Section 7.03. The Indemnitee shall supply Lessee with such
information, not within the control of Lessee, as is in such Indemnitee's
control or is reasonably available to such Indemnitee, which Lessee may
reasonably request to control or participate in any proceeding to the extent
permitted by Section 7.03.

          Section 7.07.  Survival of Obligations.  The indemnities and
                         -----------------------
agreements of the Lessee provided for in this Article 7 shall survive the
expiration or other termination of this Agreement.

          Section 7.08.  Effect of Other Indemnities.  The Lessee's obligations
                         ---------------------------
under this Article 7 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, or any other document or instrument, and the
Person seeking indemnification from the Lessee pursuant to any provision of this

discharge of it (other than the defense of payment or performance), and agrees
that it shall not be required to consent to or receive any notice of any
amendment or modification of, or waiver, consent or extension with respect to,

          ---------------------------------------------------------------------

Ladies and Gentlemen:

          As counsel to ____________________, a __________________ ("Assignee"),
I advise you as follows in connection with the Assignment and Assumption
Agreement dated as of ______________  __, ____ (the "Assignment Agreement")
between Assignee and ______________, a ____________ ("Assignor"), and the
transactions contemplated thereby. Capitalized terms used herein and not defined
herein shall have the respective meanings attributed thereto in the Assignment
Agreement. This opinion is being furnished to you pursuant to the request of
Assignee and Section 5.01(c)(v) of the Participation Agreement.

          I have, or an attorney under my supervision has, examined the
Assignment Agreement. I have, or an attorney under my supervision has, also
examined the originals, or certified, conformed, photocopied or telecopied
copies of such corporate records, certificates, instruments and other documents
as I have deemed necessary or appropriate to enable me to render the opinions
expressed herein. In all such examinations, I have assumed the genuineness of
signatures on original documents (other than those of Assignee) and the
conformity to such original documents of all copies submitted to me as
certified, conformed, photocopied or telecopied copies, and as to certificates
and telegraphic and telephonic confirmations given by public officials, I have
assumed the same to have been properly given and to be accurate. As to all
matters of fact material to my opinions, I have, when relevant facts were not
independently established, relied upon statements, representations and
warranties contained in the Assignment Agreement and upon the statements and
certificates furnished to me.

          In addition, in rendering the opinions expressed herein I have assumed
that the Assignment Agreement has been duly authorized, executed, authenticated
and delivered by Assignor and constitutes the legal, valid and binding
obligation of Assignor, enforceable against Assignor in accordance with its
terms, Assignor has the requisite power, authority and legal right to enter into
and perform its respective obligations under the Assignment Agreement and the
transactions provided for in the Assignment Agreement are not within the
prohibitions of Section 406 of the Employee Retirement Income Security Act of
1974, as amended or Section 4975 of the Internal Revenue Code of 1986, as
amended.

A. Based upon the foregoing and subject to the limitations expressed in
paragraph B below, I am of the opinion that:
<PAGE>

     1. Assignee is a ____________ duly organized, validly existing and in good
standing under the laws of [                   ] and has full corporate power
and authority to execute, deliver and perform the Assignment Agreement.

     2. The Assignment Agreement has been duly authorized, executed and
delivered by Assignee.

     3. Neither the execution and delivery of the Assignment Agreement by
Assignee, nor the consummation by Assignee of the transactions contemplated
thereby and by the Operative Agreements, conflicts with, results in a breach of
or violates any of the terms, conditions or provisions of A. the [Certificate]
[Articles] of Incorporation or By-laws of the Assignee, B. to the best of my
knowledge, any order, writ, injunction or decree of any court or governmental
authority against the Assignee or by which the Assignee or any of its properties
is bound or (iii) to the best of my knowledge, any indenture, mortgage or
contract or other material agreement or instrument to which Assignee is a party
or by which it or any of its properties is bound or constitutes a default
thereunder.

     4. To the best of my knowledge, there are no actions, suits or proceedings
pending or threatened before any court of administrative agency or arbitrator
which would materially adversely affect the ability of Assignee to perform its
obligations under the Assignment Agreement and the Operative Agreements.

     5. The Assignment Agreement constitutes a legal, valid and binding
obligation of Assignee enforceable against Assignee in accordance with the terms
thereof, except as the enforceability thereof may be limited by (a) general
equitable principles (regardless of whether such enforceability is considered in
a proceeding in equity or at law), (b) applicable bankruptcy, insolvency,
reorganization, moratorium or similar laws affecting the rights of creditors
generally and (c) public policy considerations (in the case of any indemnity
provisions contained therein).

     6. Except for filings with the Federal Aviation Administration, neither the
execution and delivery by Assignee of the Assignment Agreement, nor the
consummation by Assignee of any of the transactions contemplated thereby or by
the Operative Agreements, (a) requires the consent or approval of, the giving of
notice to, or the registration or filing with, or the taking of any action with
respect to, any governmental authority or agency of the United States or (b)
violates any law, governmental rule or regulation of the United States or the
State of [       ].

B. I am qualified to practice law in the State of [       ] and I express
no opinion as to any laws other than the laws of the State of [        ],
the General Corporation Law of the State of [        ] and the federal
laws of the United States of America.  I express no opinion herein as to (i) any
federal or state securities laws, (ii) any tax laws or (iii) any aviation law or
other laws, statutes, rules or regulations applicable due to the particular
nature of the equipment subject to the Lease. In addition, no opinion is
expressed as to matters governed by Title 49 of the United States Code, as
amended, or by any other law, statute, rule or regulation or the United States
relating to the acquisition, ownership, registration, use, operation,
maintenance, repair, replacement or sale of or the nature of aircraft. Further,
no opinion is expressed as to title to any part of the Trust Estate. In
<PAGE>

addition, I express no opinion as to the perfection or priority of any security
interests or as to the right, title or interest in or to the Trust Estate on the
part of any Person.

          This opinion is furnished by me for your sole benefit, and no other
person or entity is entitled to rely on this opinion without my express written
consent.  This opinion may not be published or reproduced in any manner or
distributed or circulated to any person or entity without my express written
consent.  This opinion is limited to the matters stated herein, and no opinion
is implied or may be inferred beyond the matters expressly stated herein.

                                        Very truly yours,
