         NOW, THEREFORE, in consideration of the mutual agreements herein
contained and other good and valuable consideration, receipt of which is
acknowledged, the parties hereto agree as follows:

SECTION 1. DEFINITIONS; INTERPRETATION OF THIS AGREEMENT

         1.1      DEFINITIONS.

         The capitalized terms used in this Agreement (including the foregoing
recitals) and not otherwise defined herein shall have the respective meanings
specified in Appendix A hereto, unless the context hereof shall otherwise
require. The "General Provisions" of Appendix A hereto are hereby incorporated
by reference herein. The capitalized terms used in this Agreement and not
defined herein or in Appendix A hereto shall have the meanings assigned thereto
in Schedule 2 to the LAPA.

         1.2      DIRECTLY OR INDIRECTLY.

         Where any provision in this Agreement refers to action to be taken by
any Person, or which such Person is prohibited from taking, such provision shall
be applicable whether such action is taken directly or indirectly by such
Person.

SECTION 2. SALE AND PURCHASE; PARTICIPATION IN THE EQUIPMENT COST; CLOSING

         2.1      SALE AND PURCHASE.

         Subject to the terms and conditions hereof and on the basis of the
representations and warranties set forth herein, the Certificate Trustee agrees
to purchase from the applicable Seller on each Delivery Date one of the Aircraft
described on Schedule IV hereto and referred to in the Notice of Delivery given
pursuant to Section 2.3(b) and in connection therewith, the Certificate Trustee
agrees to pay to the applicable Seller the Equipment Cost of the Aircraft being
delivered on such date; provided, however, that the Certificate Trustee shall
not be obligated to purchase on a Delivery Date any Aircraft that is destroyed,
damaged, defective, in unsuitable condition or

                                        2

<PAGE>

otherwise unacceptable to Lessee for lease pursuant to the Lease. The applicable
Seller shall deliver the Aircraft to the Certificate Trustee (or its designee)
and the Certificate Trustee (or its designee) shall accept such delivery of the
Aircraft on the relevant Delivery Date; provided the parties hereto agree that
(i) there shall be no more than two Delivery Dates, (ii) the initial Delivery
Date shall be the Closing Date and (iii) unless the parties to this Agreement
hereinafter agree in writing otherwise, the subsequent Delivery Date shall occur
on a Business Day on or prior to September 15, 2000.

         2.2      FUNDINGS.

         (a)      Amount of Fundings. Subject to the terms and conditions of
this Agreement and in reliance on the representations and warranties of each of
the parties hereto contained herein or made pursuant hereto, upon receipt of a
Notice of Delivery, on the related Delivery Date each Certificate Holder shall
acquire its interest in the Trust Estate and fund in accordance with Section 2.1
of the Trust Agreement, and each Lender (subject to the provisions of clause (b)
below) shall assist in funding the Equipment Cost of the Aircraft being
delivered on such date, in each case by making available to the Certificate
Trustee by wire transfer in accordance with instructions set forth in the Notice
of Delivery an amount equal to such Participant's Commitment Percentage of the
aggregate amount of the Equipment Cost of the Aircraft being delivered on such
date. Notwithstanding the foregoing, (i) the Funding by each Participant on such
Delivery Date shall not exceed such Participant's Available Commitment and (ii)
the aggregate amount of the Equipment Cost of the Aircraft being delivered on
the Closing Date to be paid by Certificate Trustee to the applicable Seller on
such Closing Date shall not exceed $19,500,000, (iii) the aggregate amount of
the Equipment Cost of the Aircraft being delivered on the subsequent Delivery
Date shall not exceed $33,500,000, and (iv) the aggregate amount of the
Equipment Cost of all the Aircraft delivered and paid for by the Certificate
Trustee shall not exceed $53,000,000. The failure of a Certificate Holder or
Facility Lender to fund its Commitment shall not release it from any liability
to the Lessee for its failure to comply with its obligations under the Operative
Documents.

         (b)      CP Lender. Subject to the terms and conditions hereof and of
the Loan Agreement, the CP Lender may, in its sole discretion, make CP Loans to
the Certificate Trustee on any Delivery Date. If the CP Lender elects not to, or
otherwise fails to, make available to the Administrative Agent on the applicable
Delivery Date an amount equal to the CP Lender's Commitment Percentage of the
aggregate amount of the Equipment Cost required by the terms hereof to be funded
on such Delivery Date, upon receipt by the applicable Facility Lenders of a
notice from the Administrator pursuant to Section 2.2 of the Loan Agreement,
such Facility Lenders shall, subject to the terms and conditions hereof and in
the Loan Agreement, make available to Administrative Agent amounts equal to
their respective Commitment Percentages of the amount of the Equipment Cost
required by the terms hereof to be funded on such Delivery Date pursuant to the
Loan Agreement. The parties hereto acknowledge that the CP Lender shall not be
obligated to make a Funding on any Delivery Date notwithstanding the use of the
term "Commitment", "Available Commitment" or "Commitment Percentage" in relation
to the CP Lender, or any other language indicating an obligation of the CP
Lender to make a Funding on a Delivery Date.

                                        3

         (c)      Notes and Certificates. Each Lender's Loan for any Aircraft
shall be evidenced by a separate Note issued to such Lender (or the
Administrative Agent for the ratable benefit of the Lenders) and repayable in
accordance with and with Interest accruing pursuant to the terms of the Loan
Agreement. The Certificate Amounts advanced for any Aircraft by each Certificate
Holder shall be evidenced by a separate Certificate issued by Certificate
Trustee to each Certificate Holder. Each Certificate shall accrue Yield at the
Yield Rate on the Certificate Amounts thereof and shall be payable as more fully
set forth in the Trust Agreement.

         (d)      Termination of Commitments. Notwithstanding anything in this
Participation Agreement to the contrary, the Commitments shall terminate and
Certificate Trustee shall not be obligated to make payment to the Seller, and no
party hereto shall be obligated to make any Fundings towards the delivery of
Aircraft, and no Delivery Date may occur after the earlier of (v) 2:00 P.M. New
York time on September 15, 2000, (w) a Lease Default or an Event of Default
shall have occurred and be continuing and written notice of such effect shall
have been given by the Agent to the Lessee, (x) the final Delivery Date, (y) any
Liquidity Purchase by a Liquidity Provider under the LAPA, or (z) any conversion
of a CP Loan to a Facility Loan under Section 2.12 of the Loan Agreement.

         2.3      CLOSING DATE AND DELIVERY DATES; PROCEDURE FOR PARTICIPATION.

         (a)      Document Delivery. All documents and instruments required to
be delivered on the Closing Date or any Delivery Date shall be delivered on or
prior to such date at the office of Moore & Van Allen, PLLC, 100 N. Tryon

as may be determined by the Certificate Trustee, the Administrative Agent and
the Lessee.

         (b)      Notice of Delivery. Not later than 5:00 P.M., Eastern time, on
the fifth Business Day preceding each Delivery Date, the Lessee shall give the
Administrative Agent notice (a "Notice of Delivery") by facsimile or other form
of telecommunication or telephone (to be promptly confirmed in writing) of the
Delivery Date of such Aircraft (which shall be a Business Day), which Notice of
Delivery shall specify in reasonable detail the Aircraft to be delivered on such
date, the Equipment Cost for such Aircraft, wire instructions for the
disbursements of the appropriate amount of the funds to the applicable Seller
and the respective amounts of the Commitments required to be funded with respect
to such Aircraft. Prior to 11:00 A.M., Eastern time, on the respective Delivery
Date, (i) each Certificate Holder shall make its Commitment required to be
funded on such Delivery Date available to the Administrative Agent, and (ii)
subject to Section 2.2(b), each Lender shall make its Commitment required to be
funded on such Delivery Date available to the Administrative Agent, in each
case, by transferring or delivering such amounts, in funds immediately available
on such Delivery Date, to the Administrative Agent; provided, that if the terms
and conditions set forth herein for making such Commitment available on such
Delivery Date have not been satisfied prior to 11:00 A.M. Eastern time on such
Delivery Date, no Participant shall be obligated to maintain the availability of
its funds unless such Participant receives a satisfactory indemnity for the
overnight investment of such funds. Delivery of any Notice of Delivery shall be
deemed to be a certification from Lessee as of the date of such Notice of
Delivery that the representations and warranties of Lessee contained herein or
in any other Operative Document shall be true and correct in all material

                                       4

respects as though made on and as of such date, except that any such
representation or warranty which is expressly made only as of an earlier date
need be true only as of such date.

         (c)      Delivery Date Occurrences. Upon receipt by the Administrative
Agent on the respective Delivery Date of the full amount of the Commitments in
respect of the Aircraft delivered on such date, the Administrative Agent on
behalf of the Certificate Trustee shall, subject to the conditions set forth in
Section 4 having been fulfilled to the satisfaction of the Certificate Trustee,
the Certificate Holders, the CP Lender, the Facility Lenders, the Lessee and the
Administrative Agent or waived by such parties as appropriate, pay to the
applicable Seller from the funds then held by the Administrative Agent, in
immediately available funds, an amount equal to the Equipment Cost for the
Aircraft delivered on such Delivery Date, and simultaneously therewith, (i) the
Lessee, individually and as authorized representative of the Certificate Trustee
(the making available by each Certificate Holder of its Commitment to be paid on
such Delivery Date shall constitute an agreement to permit Lessee to act as the
authorized representative of the Certificate Trustee with respect to such
Aircraft), shall confirm acceptance of such Aircraft from the applicable Seller
for all purposes as among the Certificate Trustee and Seller (except that there
shall not be any waiver of claims by any Person as against the applicable Seller
as a result thereof), such confirmation to be conclusively evidenced by the
execution and delivery by Lessee of a Lease Supplement covering such Aircraft,
(ii) the Seller shall deliver the Bill(s) of Sale to the Certificate Trustee
covering such Aircraft, (iii) the Certificate Trustee shall, pursuant to the
Lease, lease such Aircraft to the Lessee, and Lessee, pursuant to the Lease,
shall accept delivery of such Aircraft under the Lease (such lease, delivery and
acceptance of such Aircraft under the Lease being conclusively evidenced by the
execution and delivery by the Lessee and the Certificate Trustee of a Lease
Supplement covering such Aircraft), and (iv) the Certificate Trustee shall
execute and deliver Certificates to the Certificate Holders (on the Closing Date
only) and Notes to the Lenders (on the Closing Date only). Each of the
Certificate Trustee, the Certificate Holders, the CP Lender, the Facility
Lenders, the Administrative Agent and Lessee hereby agree to take all actions
required to be taken by it in connection therewith and pursuant to this Section
2.3(c).

         2.4      DIRECTION TO THE CERTIFICATE TRUSTEE AND ADMINISTRATIVE AGENT;
                  SATISFACTION OF CONDITIONS.

         (a)      Each Certificate Holder agrees that the making available to

the satisfaction of such Certificate Holder, to take the actions specified in

such Delivery Date.

         (b)      Each Lender agrees that the making available to the
Administrative Agent of its respective portion of its Commitment on a Delivery

Agreement and the Loan Agreement with respect to the Aircraft delivered on such
Delivery Date.

         2.5      NATURE OF TRANSACTION.

         It is the intention of the parties that notwithstanding any provision
of this Agreement to the contrary:

         (a)      the Overall Transaction constitutes an operating lease from
Certificate Trustee to the Lessee for purposes of Lessee's financial reporting;

         (b)      for federal and state income tax, property tax, bankruptcy
including the substantive law upon which bankruptcy proceedings are based) and
Uniform Commercial Code purposes:

                  (i)      the Overall Transaction constitutes a financing by
         the Participants to the Lessee, and beneficial ownership in the
         Aircraft shall be deemed to be held by, and the Overall Transaction
         preserves beneficial ownership in the Aircraft in, the Lessee and the
         obligations of Lessee to pay the Interest and Yield portions of Basic
         Rent shall be treated as payments of interest to the Participants, and
         the payment by Lessee of any amounts in respect of the Lease Balance
         shall be treated as payments of principal to the Participants;

                  (ii)     the Certificate Trustee's holding of any title in the
         Aircraft shall be as security for Lessee's obligations under the
         Operative Documents, and the Lease grants a security interest or a
         lien, as the case may be, in the Aircraft and the other Lease
         Collateral in favor of the Certificate Trustee, and for the benefit of
         the Participants; and

                  (iii)    the Security Agreement creates liens and security
         interests in the Collateral defined therein for the benefit of all of
         the Participants.

Nevertheless, the Lessee and each Financing Party acknowledges and agrees that
none of such entities has made any representations or warranties concerning the
tax, accounting or legal characteristics of the Operative Documents or any
aspect of the Overall Transaction and that each such entity has obtained and
relied upon such tax, accounting and legal advice concerning the Operative
Documents and the Overall Transaction as such party deems appropriate.

         2.6      AMOUNTS DUE UNDER LEASE.

         Anything else herein or elsewhere to the contrary notwithstanding, it
is the intention of Lessee, Certificate Trustee, and Participants that from and
after the Closing Date: (i) the amount and timing of installments of Basic Rent
due and payable from time to time from the Lessee under the Lease on a Payment
Date shall be equal to the aggregate payments due and payable in respect of
principal and accrued Interest on the Notes and redemptions of Certificate
Amount and accrued Yield on the Certificates on such Payment Date; (ii) if
Lessee becomes obligated to purchase an Aircraft under the Lease, the principal
of the corresponding Loans, Certificate Amounts, all accrued and unpaid Interest
and all accrued and unpaid Yield thereon and all other obligations of the Lessee
owing to the Financing Parties with respect thereto shall be paid in full by the
Lessee in accordance with Sections 21 and 22 of the Lease; (iii) if Lessee
properly elects

                                       6
<PAGE>

the Sale Option with respect to any Aircraft and remarkets such Aircraft in
accordance with Section 23 of the Lease, on the Expiration Date Lessee shall
only be required to pay the Sale Proceeds of the sale of such Aircraft and, if
the Sale Proceeds are less than the Lease Balance of such Aircraft, the amount
of such difference but not more than the Sale Recourse Amount for such Aircraft,
all in accordance with Section 23 of the Lease, and any other amounts due
pursuant to Section 7.9 hereof and such Section 23 of the Lease (which aggregate
amounts may be less than the Lease Balance of such Aircraft); and (iv) upon a
Lease Event of Default resulting in an acceleration of the Lessee's obligation
to purchase the Aircraft under the Lease, the amounts then due and payable by
the Lessee under Section 14 of the Lease shall include all amounts necessary to
pay in full the outstanding principal under the Loans, the Certificate Amounts
and all accrued Interest and Yield thereon, plus all other amounts then payable
by the Lessee to the Financing Parties under the Operative Documents.

         2.7      COMPUTATIONS.

         For all purposes under the Operative Documents, all computations of
Interest, Yield and other accrued amounts (including, without limitation, the
Overdue Rate) shall be made on the basis of a 360-day year and the actual days
elapsed, subject to the last sentence in Section 2.8 hereof, Section 2.5 of the
Trust Agreement and Section 2.7 of the Loan Agreement, as applicable.

         2.8      DETERMINATION OF INTEREST AND YIELD.

         The amount of principal outstanding on the Loans shall accrue Interest
as provided in Section 2.6(a) of the Loan Agreement. The amount of Certificate
Amounts outstanding from time to time shall accrue Yield at the per annum rate
equal to the Yield Rate. Administrative Agent shall as soon as practicable, but
in no event later than 11:00 A.M., New York time, two Business Days prior to the
effectiveness of each LIBO Rate, notify Borrower, Lessee and the Participants of
such LIBO Rate, the corresponding rate of interest per annum (if such Interest
is calculated by reference to the LIBO Rate) and Yield Rate and the applicable
Payment Period, as applicable, but failure to so notify shall not affect the
obligations of the parties hereunder or under the other Operative Documents. If
all or any portion of the principal under the Loans, the Certificate Amounts,
any accrued Interest or Yield payable thereon or any other amount payable
hereunder shall not be paid when due (whether at stated maturity, acceleration
or otherwise), such overdue amount shall bear interest at a rate per annum which
is equal to the Overdue Rate and shall be payable by Certificate Trustee (and an
equal amount of Supplemental Rent shall be due and payable at such time by the
Lessee) from time to time on demand. If at any time the rate on which either
Interest or Yield accrue is determined by reference to the LIBO Rate and such
rate cannot be determined by reference to a LIBO Rate (or if such rate becomes
unavailable or illegal) then the rate on which Interest and Yield accrues, as
applicable, shall be determined as provided in Section 7.4 hereof.

         2.9      OBLIGATIONS SEVERAL.

         The obligations of the Participants hereunder or elsewhere in the
Operative Documents shall be several and not joint; and no Participant shall be
liable or responsible for the acts or defaults of any other party hereunder or
under any other Operative Document.

         2.10     HIGHEST LAWFUL RATE.

         It is the intention of the parties hereto to conform strictly to
applicable usury laws and, anything herein to the contrary notwithstanding, the
obligations of (x) Lessee to Certificate Trustee under this Participation
Agreement and the Lease, (y) Certificate Trustee to the Certificate Holders
under the Trust Agreement and the Certificates and to the Lenders under the Loan
Agreement and the Notes, and (z) either Lessee or the Certificate Trustee or any
other party under any other Operative Document shall be subject to the
limitation that payments of interest or of other amounts constituting interest
under Applicable Laws and Regulations shall not be required to the extent that
receipt thereof would be in excess of the Highest Lawful Rate (as defined
below), or otherwise contrary to provisions of law applicable to the recipient
limiting rates of interest which may be charged or collected by the recipient.
Accordingly, if the transactions or the amount paid or otherwise agreed to be
paid for the use, forbearance or detention of money under this Participation
Agreement, the Lease, the Trust Agreement, the Certificates, the Loan Agreement,
the Notes or any other Operative Document would exceed the Highest Lawful Rate
or otherwise be usurious under Applicable Laws and Regulations (including
without limitation the federal and state laws of the United States of America,
or of any other jurisdiction whose laws may be mandatorily applicable) with
respect to the recipient of any such amount, then, in that event,
notwithstanding anything to the contrary in this Participation Agreement, the
Lease, the Trust Agreement, the Certificates, the Loan Agreement, the Notes or
any other Operative Document, it is agreed as follows as to the recipient of any
such amount:

         (a)      the provisions of this Section 2.10 shall govern and control
over any other provision in this Participation Agreement, the Lease, the Trust
Agreement, the Certificates, the Loan Agreement, the Notes and any other
Operative Document and each provision set forth therein is hereby so limited;

         (b)      the aggregate of all consideration which constitutes interest
under Applicable Laws and Regulations that is contracted for, charged or
received under this Participation Agreement, the Lease, the Trust Agreement, the
Certificates, the Loan Agreement, the Notes or any other Operative Document
shall under no circumstances exceed the maximum amount of interest allowed by
Applicable Laws and Regulations (such maximum lawful interest rate, if any, with
respect to such recipient herein called the "Highest Lawful Rate"), and all
amounts owed under this Participation Agreement, the Lease, the Trust Agreement,
the Certificates, the Loan Agreement, the Notes and any other Operative Document
shall be held subject to reduction and: (i) the amount of interest which would
otherwise be payable to the recipient hereunder and under this Participation
Agreement, the Lease, the Trust Agreement, the Certificates, the Loan Agreement,
the Notes and any other Operative Document, shall be automatically reduced to
the amount allowed under Applicable Laws and Regulations, and (ii) any unearned
interest accrued, payable or paid in excess of the Highest Lawful Rate shall be
credited to the payor by the recipient (or, if such obligation shall have been
paid in full, refunded to the payor);

         (c)      all sums paid, or agreed to be paid for the use, forbearance
and detention of the money under this Participation Agreement, the Lease, the
Trust Agreement, the Certificates, the Loan Agreement, the Notes or any other
Operative Document shall, to the extent permitted by Applicable Laws and
Regulations, be amortized, prorated, allocated and spread throughout the

                                       8
<PAGE>

full term of such indebtedness until payment in full so that the actual rate of
interest is uniform throughout the full term thereof;

         (d)      if at any time the interest, together with any other fees,
late charges and other sums payable pursuant to or in connection with this
Participation Agreement, the Lease, the Trust Agreement, the Certificates, the
Loan Agreement, the Notes and any other Operative Document executed in
connection herewith or therewith and deemed interest under Applicable Laws and
Regulations, exceeds that amount which would have accrued at the Highest Lawful
Rate, the amount of interest and any such fees, charges and sums to accrue to
the recipient of such interest, fees, charges and sums pursuant to the Operative
Documents shall be limited, notwithstanding anything to the contrary in the
Operative Documents, to that amount which would have accrued at the Highest
Lawful Rate for the recipient, but any subsequent reductions, as applicable,
shall not reduce the interest to accrue pursuant to the Operative Documents
below the recipient's Highest Lawful Rate until the total amount of interest
payable to the recipient (including all consideration which constitutes
interest) equals the amount of interest which would have been payable to the
recipient (including all consideration which constitutes interest), plus the
amount of fees which would have been received but for the effect of this Section
2.10.

SECTION 3. REPRESENTATIONS AND WARRANTIES

         3.1      REPRESENTATIONS AND WARRANTIES OF THE TRUST COMPANY AND THE
                  CERTIFICATE TRUSTEE.

         Each of the Certificate Trustee and the Trust Company, in its
individual capacity, represent and warrant to the other parties to this
Agreement, notwithstanding the provisions of Section 9.11 or any similar
provision in any other Operative Document, that, as of the Closing Date and each
Delivery Date:

         (a)      Chief Executive Office. Its chief executive office or place of
business (if it has only one place of business) and the place where the
documents, accounts and records relating to the Overall Transaction are kept are
located at its address set forth in Schedule III attached hereto.

         (b)      Due Organization, etc. The Trust Company is a national banking
association duly organized and validly existing in good standing under the laws
of the United States and has full corporate power and authority to execute,
deliver and perform its obligations: (i) in its individual capacity under the
Trust Agreement and, to the extent it is a party hereto in its individual
capacity, this Participation Agreement, and (ii) acting as Certificate Trustee
under the Trust Agreement, under this Participation Agreement and each other
Operative Document to which it is or will be a party as Certificate Trustee.

         (c)      Due Authorization; Enforceability, etc. This Participation
Agreement and each other Operative Document to which the Trust Company is or
will be a party have been or will be (to the extent it is to be a party thereto
in its individual capacity), duly authorized, executed and delivered by or on
behalf of the Trust Company (in its individual capacity) and are, or upon
execution and delivery will be, legal, valid and binding obligations of the
Trust Company (in its individual capacity), enforceable against it in accordance
with their respective terms, except as

                                       9
<PAGE>

such enforceability may be limited by applicable bankruptcy, insolvency, or
similar laws affecting creditors' rights generally and by general equitable
principles. The Operative Documents to which Certificate Trustee is a party
(assuming the due authorization, execution and delivery of the Trust Agreement
by the Certificate Holders) have been duly authorized, executed and delivered
and constitute the legal, valid and binding obligation of Certificate Trustee
(acting solely as Certificate Trustee under the Trust Agreement, and not in its
individual capacity), enforceable against it in accordance with its terms,
except as such enforceability may be limited by applicable bankruptcy,
insolvency or similar laws affecting creditors' rights generally and by general
equitable principles.

         (d)      No Conflict. The execution and delivery by (i) the Trust
Company, in its individual capacity, of the Trust Agreement and, to the extent
it is a party hereto in its individual capacity, this Participation Agreement
and (ii) the Certificate Trustee of each Operative Document to which Certificate
Trustee is or will be a party, are not and will not be, and the performance by
the Trust Company, in its individual capacity, or the Certificate Trustee, as
the case may be, of its obligations under each are not and will not be,
inconsistent with the articles of association or by-laws of the Trust Company,
do not and will not contravene any Applicable Laws and Regulations of the United
States of America or the State of Utah relating to the banking or trust powers
of the Trust Company and do not and will not contravene any provision of, or
constitute a default under, any indenture, mortgage, chattel mortgage, deed of
trust, lease, conditional sales contract, loan or credit arrangement or other
agreement or instrument to which the Trust Company is a party or by which it or
its properties may be bound or affected.

         (e)      No Approvals, etc. Neither the execution and delivery by the
Trust Company in its individual capacity or (assuming the due authorization,
execution and delivery of the Trust Agreement by each Certificate Holder) as
Certificate Trustee, as the case may be, of any of the Operative Documents to
which it is a party requires the consent or approval of, or the giving of notice
to or registration with, or the taking of any other action in respect of, any
United States of America or Utah Authority governing its banking practices.

         (f)      Certificate Trustee Liens. Each Aircraft and the Lease and
other Collateral are free and clear of all Certificate Trustee Liens
attributable to the Trust Company or the Certificate Trustee and no act or
omission has occurred which would give rise to a Certificate Trustee Lien
attributable to the Trust Company or the Certificate Trustee.

         (g)      Litigation. There is no action, proceeding or investigation
pending or, to the best knowledge of the Trust Company, threatened against the
Trust Company or Certificate Trustee which questions the validity of any of the
Operative Documents, and there is no action, proceeding or investigation pending
or, to the best knowledge of the Trust Company, threatened which is likely to
result, either in any case or in the aggregate, in any material adverse change
in the ability of the Trust Company or Certificate Trustee to perform its
obligations under the Operative Documents to which it is a party.

         (h)      Securities Act. Neither the Trust Company nor Certificate
Trustee nor any Person authorized to act on its behalf has offered or sold any
interest in the Notes or Certificates, or in any similar security relating to
the Aircraft, or in any security, the offering of which for the purposes of the
Securities Act would be deemed to be part of the same offering as the offering
of

                                       10
<PAGE>

the aforementioned securities, to, or solicited any offer to acquire any of the
same from, any Person other than, in the case of the Notes, the Lenders, and in
the case of the Certificates, the Certificate Holders, each of whom was offered
a portion thereof at private sale for investment, and neither the Trust Company
nor Certificate Trustee nor any Person authorized to act on its behalf will take
any action which would require registration of the offer or sale of any interest
in the Notes or Certificates pursuant to the provisions of Section 5 of the
Securities Act or any state securities laws.

         (i)      No Taxes. There are no Taxes payable by the Certificate
Trustee or the Trust Company imposed by the State of Utah or any political
subdivision thereof or by the United States of America in connection with the
execution and delivery by the Trust Company of the Trust Agreement, and the
execution and delivery by the Trust Company or the Certificate Trustee, as the
case may be, of this Agreement or the other Operative Documents to which it is a
party solely because the Trust Company is a national banking association with
its principal place of business in Salt Lake City, Utah and performs certain of
its duties as the Certificate Trustee in the State of Utah; and there are no
Taxes payable by the Certificate Trustee or the Trust Company imposed by the
State of Utah or any political subdivision thereof or by the United States of
America in connection with the acquisition of its interest in the Trust Estate
(other than franchise or other Taxes based on or measured by any fees or
compensation received by the Trust Company for services rendered in connection
with the transactions contemplated hereby) solely because the Trust Company is a
national banking association with its principal place of business in Salt Lake
City, Utah and performs certain of its duties as the Certificate Trustee in the
State of Utah.

         3.2      REPRESENTATIONS AND WARRANTIES OF LESSEE.

         The Lessee hereby represents and warrants to the other parties to this
Agreement that, as of the Closing Date and each Delivery Date:

         (a)      Due Organization, Etc. The Lessee is a corporation duly
organized, validly existing and in good standing under the laws of the State of
Michigan. Each Material Subsidiary is a corporation duly organized, validly
existing and in good standing under the laws of the jurisdiction of its
incorporation in which failure to be so duly organized, validly existing and in
good standing under the laws of the jurisdiction of its incorporation would have
a Material Adverse Effect. The Lessee and each of its Material Subsidiaries are
qualified to do business in and are in good standing under the laws of each
jurisdiction in which failure to be so qualified would have a Material Adverse
Effect.

         (b)      Due Authorization, etc. The execution, delivery and
performance by the Lessee of the Operative Documents (i) are within the Lessee's
corporate powers and have been duly authorized by all necessary corporate action
or (ii) do not contravene the Lessee's Certificate of Incorporation, applicable
law or any material contractual restriction binding on or affecting the Lessee
or any of its Material Subsidiaries.

         (c)      Governmental Consent. No authorization or approval or other
action by, and no notice to or filing with, any governmental authority or
regulatory body is required for the due execution, delivery and performance by
the Lessee of this Agreement and the other Operative

                                       11
<PAGE>

Documents, other than those that have been, or contemporaneously with the
delivery of the Aircraft will be, obtained, all of which are listed on Schedule
3.2(c).

         (d)      Validity. The Operative Documents to which the Lessee is a
party constitute legal, valid and binding obligations of the Lessee enforceable
against the Lessee in accordance with their terms subject to the effect of
applicable bankruptcy, insolvency, arrangement, moratorium and other similar
laws affecting creditors' rights generally and to the application of general
principles of equity.

         (e)      Condition of the Lessee. (i) The consolidated balance sheet of
the Lessee and its Subsidiaries as of February 26, 1999, and the related
consolidated statements of income and retained earnings of the Lessee and its
Subsidiaries for the fiscal year then ended, copies of which have been
previously furnished to the Administrative Agent and the Participants, fairly
present the consolidated financial condition of the Lessee and its Subsidiaries
as at such date and the results of the operations of the Lessee and its
Subsidiaries for the periods ended on such dates, all in accordance with GAAP
consistently applied, and (ii) since February 26, 1999, there has been no
material adverse change in the business, condition (financial or otherwise),
results of operations or prospects of the Lessee and its Subsidiaries, taken as
a whole.

         (f)      Litigation. (i) There is no pending action or proceeding
against the Lessee or any of its Subsidiaries before any court, governmental
agency or arbitrator, and (ii) to the knowledge of the Lessee, there is no
pending or threatened action or proceeding affecting the Lessee or any of its
Subsidiaries before any court, governmental agency or arbitrator, which in
either case, affects any Aircraft or in the reasonable judgment of the Lessee
could reasonably be expected to have a Material Adverse Effect.

         (g)      Margin Regulations. The Lessee is not engaged in the business
of extending credit for the purpose of purchasing or carrying Margin Stock, and
no proceeds of any Funding will be used to purchase or carry any Margin Stock or
to extend credit to others for the purpose of purchasing or carrying any Margin
Stock in any manner that violates, or would cause a violation of Regulation T,
Regulation U or Regulation X. Less than 10 percent of the fair market value of
the assets of (i) the Lessee or (ii) the Lessee and its Subsidiaries consists of
Margin Stock.

         (h)      Payment of Taxes. The Lessee and each of its Subsidiaries have
filed or caused to be filed all material tax returns (federal, state, local and
foreign) required to be filed and paid all material amounts of taxes shown
thereon to be due, including interest and penalties, except for such taxes as
are being contested in good faith and by proper proceedings and with respect to
which appropriate reserves are being maintained by the Lessee or any such
Subsidiary, as the case may be.

         (i)      Governmental Regulation. The Lessee is not subject to
regulation under the Public Utility Holding Company Act of 1935, the Federal
Power Act, the Interstate Commerce Act or the Investment Company Act of 1940,
each as amended, or to any Federal or state statute or regulation limiting its
ability to incur indebtedness for money borrowed. No Subsidiary of the Lessee is
subject to any regulation that would limit the ability of the Lessee to enter
into or perform its obligations under this Agreement.

                                       12
<PAGE>

         (j)      ERISA.

                  (i)      No ERISA Event which might result in liability of the
         Lessee or any of its ERISA Affiliates in excess of $10,000,000 (or, in
         the case of an event described in clause (v) of the definition of ERISA
         Event, $750,000) (other than for premiums payable under Title IV of
         ERISA) has occurred or is reasonably expected to occur with respect to
         any Pension Plan.

                  (ii)     Schedule B (Actuarial Information) to the most
         recently completed annual report prior to the Closing Date (Form 5500
         Series) for each Plan, which report has been filed with the Internal
         Revenue Service by the Lessee or an ERISA Affiliate, copies of which
         have been furnished to the Administrative Agent and the Participants,
         is complete and, to the best knowledge of the Lessee, accurate, and
         since the date of such Schedule B there has been no material adverse
         change in the funding status of any such Plan.

                  (iii)    Neither the Lessee nor any ERISA Affiliate has
         incurred, or, to the best knowledge of the Lessee, is reasonably
         expected to incur, any Withdrawal Liability to any Multiemployer Plan
         which has not been satisfied or which is or might be in excess of
         $10,000,000.

                  (iv)     Neither the Lessee nor any ERISA Affiliate has been
         notified by the sponsor of a Multiemployer Plan that such Multiemployer
         Plan is in reorganization or has been terminated, within the meaning of
         Title IV of ERISA, and, to the best knowledge of the Lessee, no
         Multiemployer Plan is reasonably expected to be in reorganization or to
         be terminated within the meaning of Title IV of ERISA.

         (k)      Environmental Matters. (i) The Lessee and each of its
Subsidiaries is in compliance in all material respects with all Environmental
Laws the non-compliance with which could reasonably be expected to have a
Material Adverse Effect and (ii) there has been no "release or threatened
release of a hazardous substance" (as defined by the Comprehensive Environmental
Response, Compensation and Liability Act of 1980, as amended, 42 U.S.C. Section
9601 et seq.) or any other release, emission or discharge into the environment
of any hazardous or toxic substance, pollutant or other materials from the
Lessee's or its Subsidiaries' property other than as permitted under applicable
Environmental Law and other than those which would not have a Material Adverse
Effect. Other than disposals (A) for which the Lessee has been indemnified in
full or (B) which would not have a Material Adverse Effect, all "hazardous
waste" (as defined by the Resource Conservation and Recovery Act, 42 U.S.C.
Section 6901 et seq. (1976) and the regulations thereunder, 40 CFR Part 261
("RCRA")) generated at the Lessee's or any Subsidiaries' properties have in the
past been and shall continue to be disposed of at sites which maintain valid
permits under RCRA and any applicable state or local Environmental Law.

         (l)      Disclosure. As of the Closing Date, to the best of the
Lessee's knowledge, no representation or warranty of the Lessee or any of its
Subsidiaries contained in this Agreement or any other Operative Document or in
any other document, certificate or written statement furnished to the
Administrative Agent or to the Participants by or on behalf of the Lessee or any
of its Subsidiaries contains any untrue statement of a material fact or omits to
state a material fact necessary in order to make the statements contained in
such agreements, documents,

                                       13
<PAGE>

certificates and statements not misleading in light of the circumstances in
which the same were made.

         (m)      No Default. No Lease Event of Default or Lease Default exists
or would result from the Lessee entering into and performing the Operative
Documents to which it is a party. No Event of Loss has occurred with respect to
any Aircraft to be delivered on the Delivery Date with respect to which this
representation or warranty is made.

         (n)      Chief Executive Office. Lessee's chief executive office, as
such term is used in Section 9-103(3) of the UCC, is located in Grand Rapids,
Michigan.

         (o)      Private Offering. Excluding the effect of any failure of the
representations and warranties set forth in Sections 3.1(h) and 3.3(f), (g) and
(i) to be true and correct, the issuance, sale and delivery of the Certificates,
the Notes and the interests in the Operative Documents under the circumstances
contemplated hereby do not require the registration or qualification of such
Certificates, Notes or interests under the Securities Act, any state securities
laws, or the Trust Indenture Act of 1939, as amended. Neither Lessee nor anyone
authorized to act on its behalf has, directly or indirectly, solicited any
offers to acquire, offered or sold: (i) any interest in the Certificates, Notes,
the Aircraft, the Lease or the Operative Documents in violation of Section 5 of
the Securities Act or any state securities laws, or (ii) any interest in any
security or lease the offering of which, for purposes of the Securities Act or

full and correct entries shall be made of all financial transactions and the

this Agreement and the other Operative Documents and the Overall Transaction.
Lessee, at its cost and expense, will cause all Financing Statements (including

state securities laws.

         (l)      Rates. With respect to each determination of Loans,
Certificate Amounts, Interest and Yield pursuant to this Agreement, the Loan

Lessee agrees with and for the benefit of the Financing Parties that, not
withstanding any language to the contrary contained in this Agreement or any
other Operative Document, if the Credit Agreement is terminated or expires and
is not replaced, then the Incorporated Covenants (and all other relevant
provisions of the Credit Agreement related thereto, including without limitation
the defined terms which are used in the Incorporated Covenants, hereinafter
referred to as the "Additional Incorporated Terms") shall (i) remain in effect
in the respective form thereof as of such date of termination or expiration of
the Credit Agreement (giving effect to any waiver, amendment, modification
and/or replacement of the Credit Agreement or any term or provision of the
Incorporated Covenants or the Additional Incorporated Terms occurring subsequent
to the date of this Agreement but subject to the

referred to as a "New Facility") the relevant covenants and additional terms in
the New Facility which correspond to the covenants contained in Section 5.02(d),
(e) and (f) and the additional terms shall automatically replace the prior
Incorporated Covenants and Additional Incorporated Terms and become the
Incorporated Covenants and Additional Incorporated Terms hereunder.
Notwithstanding the foregoing, in the event that any such Incorporated Covenants
or Additional Incorporated Terms conflict with the covenants and agreements of
the Lessee under the Operative Documents, the provisions of the Operative
Documents shall govern to the extent of such conflict.

         (p)      Liens, Etc. The Lessee will not create or suffer to exist, or
permit any of its Subsidiaries to create or suffer to exist, any Lien, upon or
with respect to any of its properties, whether now owned or hereafter acquired,
or assign, or permit any of its Subsidiaries to assign, any right to receive
income, in each case to secure or provide for the payment of any Debt of any
Person, unless the Lessee's obligations hereunder shall be secured equally and
ratably with, or prior to, any such Debt; provided however that the foregoing
restriction shall not apply to the following Liens which are permitted:

                  (i)      Liens on assets of any Subsidiary of the Borrower
existing at the time such Person becomes a Subsidiary (other than any such Lien

                  (ii)     purchase money Liens upon or in any property acquired

amount of Debt secured by such Lien does not exceed 100% of the purchase price
of such property and transaction costs relating to such acquisition) and Liens
existing on such property at the time of its acquisition (other than any such
Lien created in contemplation of such acquisition); and the interest of the
lessor thereof in any property that is subject to a Capital Lease;

                  (iii)    any Lien securing Debt that was incurred prior to or
during construction or improvement of property for the purpose of financing all
or part of the cost of such construction or improvement, provided that the
amount of Debt secured by such Lien does not exceed 100% of the fair market
value of such property after giving effect to such construction or improvement;

                  (iv)     any Lien securing Debt of a Subsidiary owing to the
Lessee;

                  (v)      Liens resulting from any extension, renewal or
replacement (or successive extensions, renewals or replacements), in whole or in
part, of any Debt secured by any Lien referred to in clauses (i), (ii) and (iii)
above so long as (x) the aggregate principal amount of such Debt shall not
increase as a result of such extension, renewal or replacement and (y) Liens
resulting from any extension, renewal or replacement shall cover only such
property which secured the Debt that is being extended, renewed or replaced;

                                       29
<PAGE>

                  (vi)     Liens on accounts receivable resulting from the sale
of such accounts receivable by the Lessee or a Subsidiary of the Lessee, so long

accounts receivable does not exceed $200,000,000;

                  (vii)    Liens other than Liens described in clauses (i)

         For purposes of this Section 5.1(p) the following terms have the
following meanings:

         "Capital Lease" means, with respect to any Person, any lease of any
property by that Person as lessee which would, in conformity with GAAP, be
required to be accounted for as a capital lease on the balance sheet of that
Person.

         Certificate Trustee or the Trust Company, as the case may be, will
         cause in its individual capacity restitution to be made to the Trust
         Estate in the amount of any diminution of the value thereof as a result
         of such Certificate Trustee Lien; and

                  (iii)    will not, through its own actions or inactions,
         interfere in the quiet enjoyment, use, operation or possession of any
         Aircraft by Lessee unless a Lease Event of Default shall have occurred
         and be continuing.

         (b)      Trust Agreement. Without prejudice to any right under the
Trust Agreement of the Trust Company to resign as Certificate Trustee, or the
Certificate Holders' rights under the Trust Agreement to remove Certificate
Trustee, each of the Certificate Holders hereby agrees with Lessee (so long as
no Event of Default shall have occurred and be continuing), the Lenders and the
Agents (i) not to terminate or revoke the trust created by the Trust Agreement,
except as permitted by the Trust Agreement, prior to the later of the Expiration
Date or the payment in full of the obligations under the Notes and Certificates,
(ii) not to amend, supplement, terminate or revoke or otherwise modify any
provision of the Trust Agreement prior to the Expiration Date in such a manner
as to materially and adversely affect the rights of any such party, (iii) except
as otherwise expressly authorized under the Operative Documents, not to withdraw
from the Trust Estate any funds other than amounts payable to it by Certificate
Trustee as distributions of Basic Rent and Supplemental Rent without the prior
written consent of each such party and (iv) to comply with all of the terms of
the Trust Agreement and the other Operative Documents applicable to it, the
nonperformance of which is reasonably likely to adversely affect such party.

         (c)      Successor Certificate Trustee. Certificate Trustee or any
successor may resign or be removed by the Required Certificate Holders as
Certificate Trustee, a successor Certificate Trustee may be appointed, and a
corporation may become Certificate Trustee under the Trust Agreement, only in
accordance with the provisions of the Trust Agreement. Notwithstanding anything
to the contrary contained in this Participation Agreement or the Trust
Agreement, so long as no Event of Default shall be continuing, the appointment
of a successor Certificate Trustee shall be subject to the consent of the Lessee
(such consent not to be unreasonably withheld or delayed).

         (d)      Indebtedness; Other Business. The Trust Company agrees that
it, in its capacity as Certificate Trustee, shall not, on behalf of the Trust,
contract for, create, incur or assume any Indebtedness, or other obligation or
contractual commitment or enter into any business or other activity, other than
pursuant to or under the Operative Documents and, for the benefit of Lessee,
Agents and the Lenders, the Trust Company agrees in such capacity to be bound by
Section 1.2(b) of the Trust Agreement.

         (e)      Change of Principal Place of Business. The Trust Company
agrees that it, in its capacity as Certificate Trustee, shall give prompt notice
to the Certificate Holders, Lessee and Agents, if Certificate Trustee's
principal place of business or chief executive office (if it has

                                       31
<PAGE>

more than one place of business), or the office where the records concerning the
accounts or contract rights relating to the Overall Transaction are kept, shall
cease to be located at the address in the State of Utah set forth on Schedule
III, or if it shall change its name or identity.

         (f)      Loan Agreement. For the benefit of Lessee, the Trust Company
and each Participant hereby agree that, so long as the Lease is in effect,
Certificate Trustee shall not consent to or permit any amendment of the terms
and provisions of the Loan Agreement, the Security Agreement or any Note,
whether or not any Event of Default shall have occurred and be continuing, if
any such amendment or action would have the effect of increasing the obligations
of Lessee or decreasing the rights of Lessee or would otherwise adversely affect
Lessee, in each case without the prior written consent of Lessee.

         (g)      Depreciation. Prior to the Expiration Date (and thereafter
unless the Lease shall have terminated and Lessor shall not have conveyed title
to the Aircraft to any other Person), neither Certificate Trustee nor any
Participant shall claim any federal or state tax attributes or benefits
(including depreciation) relating to the Aircraft unless required to do so by an
appropriate taxing authority or after a clearly applicable change in Applicable
Laws or as a protective response to a proposed adjustment by an Authority;
provided, however, that if an appropriate taxing authority shall require
Certificate Trustee or any Participant to claim any such federal or state tax
attributes or benefits, such Person shall promptly notify the Lessee thereof and
shall permit Lessee to contest such requirement in a manner similar to the
contest rights provided in, and subject to any applicable limitation to a
contest contained in, Section 7.2(b).

         (h)      Insolvency Proceedings. Each of the Participants, Certificate
Trustee, in its individual capacity, each Agent, in its respective individual
capacity, and Lessee covenants as to itself, not jointly with any other Person,
that it shall not (i) commence any action, proceeding or other case with respect
to Certificate Trustee under any existing or future law of any jurisdiction,
domestic or foreign, relating to bankruptcy, insolvency, reorganization,
arrangement, winding up, liquidation, dissolution, composition or other relief
with respect to indebtedness, (ii) seek appointment of a receiver, trustee,
custodian or other similar official with respect to Certificate Trustee and for
all or any substantial benefit of the creditors of Certificate Trustee, or (iii)
take any action in furtherance of, or indicating its consent to, approval of, or
acquiescence in, any of the acts set forth in this clause (h), except in each
case, as expressly permitted pursuant to the Loan Agreement upon the occurrence
of a Loan Event of Default.

         (i)      Release of Documents. Administrative Agent hereby agrees that,
upon a sale of the Aircraft pursuant to the terms of the Lease and payment of
all amounts due and owing from Lessee under the Operative Documents or repayment
in full of all Loans and Certificate Amounts and all other amounts due and owing
from Lessee under the Operative Documents to Administrative Agent and the
Participants, Administrative Agent shall promptly execute and deliver to the
Lessee a release of the Security Agreement, and releases of all other Liens
created by the Operative Documents, and termination statements for any financing
statements relating to the Aircraft which are then of record naming
Administrative Agent as secured party or assignee thereof.

         6.4      PARTICIPATIONS.

         Any Participant may at any time sell to one or more commercial banks or
other Persons (each of such commercial banks and other Persons being herein
called a "Sub-Participant") participating interests in all or a portion of its
rights and obligations under this Participation Agreement, the other Operative
Documents, or its Notes or Certificates (including, without limitation, all or
portion of the Rent owing to it); provided, however, that:

         (a)      no such participation shall be effective unless such
Sub-participant complies with the obligations set forth in Section 7.3 hereof;

         (b)      no participation contemplated in this Section 6.4 shall
relieve such Participant from its obligations hereunder or under any other
Operative Document;

         (c)      such Participant shall remain solely responsible for the
performance of its Commitment and such other obligations;

         (d)      Lessee shall continue to deal solely and directly with such
Participant in connection with such Participant's rights and obligations under
this Participation Agreement and each of the other Operative Documents;

         (e)      each such Sub-Participant will make representations and
warranties to the Participant that are consistent with Section 3.3, mutatis
mutandis;

         (f)      no Sub-Participant shall be entitled to have any right to vote
or grant or withhold consents or otherwise to require such Participant or Lessee
to take or refrain from taking any action hereunder or under any other Operative
Document; and

         (g)      no Sub-Participant shall be entitled to the benefits of
Sections 7.4 through 7.6 hereof in excess of the right of the Participant
selling the relevant participating interest.

         Notwithstanding the provisions of Section 6.3 and the foregoing
provisions of this Section 6.4, any sale of a percentage interest from the CP
Lender to any Liquidity Bank pursuant to the LAPA shall not be subject to the
provisions of Section 6.3 or the foregoing provisions of this Section 6.4, but
instead the provisions of the LAPA and the applicable provisions of this
Participation Agreement, other than the provisions of Section 6.3 and the
foregoing provisions of this Section 6.4, shall be applicable.

         6.5      DISCLOSURE OF INFORMATION; PLEDGE UNDER REGULATION A.

         (a)      Subject to Section 9.18 hereof, any Participant, any Agent or
Certificate Trustee may, in connection with any assignment or participation or
proposed assignment or participation pursuant to Sections 6.3 or 6.4 or this
Section 6.5 hereof, disclose to the assignee or participant or proposed assignee
or participant any information relating to Lessee.

         (b)      Anything in Sections 6.3, or 6.4 or this Section 6.5 hereof to
the contrary notwithstanding, any Lender may, without the consent of Lessee,
assign and pledge all or any portion of the Notes held by it to any Federal
Reserve Bank, the United States Treasury or to any

                                       35
<PAGE>

other financial institution as collateral security pursuant to Regulation A of
the F.R.S. Board and any operating circular issued by the Federal Reserve System
and/or the Federal Reserve Bank or otherwise, but no such assignment shall
relieve any Lender of its obligations hereunder.

         6.6      ASSIGNMENT OF CP LENDER'S INTEREST IN LOAN TO LIQUIDITY BANKS.

         In the event the CP Lender (i) exercises its option to sell all of its
interests under its Loans to the Liquidity Banks pursuant to Section 3.2(a) of
the LAPA or (ii) is required to sell all of its interests under its Loans to the
Liquidity Banks pursuant to Section 3.2(g) of the LAPA, the CP Lender, without
further act, will be deemed to have assigned to the Liquidity Banks on a several
basis in accordance with their Percentage Interests all of its right, title and
interest in the Operative Documents, and the Liquidity Banks will be deemed to
have assumed as of the date of transfer on a several basis as aforesaid all
obligations of the CP Lender arising on or after the date of transfer. In the
event the CP Lender assigns all or a portion of its Loan and its rights and
interests under the LAPA in accordance with provisions of Section 10.1(a) of the
LAPA, then the CP Lender, without further act, will be deemed to have assigned
to such assignee all or a portion, as applicable, of its right, title and
interest in the Operative Documents and such assignee will be deemed to have
assumed all or a portion, as applicable, of the obligations of the CP Lender
arising on or after the date of such assignment. Administrator shall promptly
notify Lessee of any assignment pursuant to this Section 6.6.

         6.7      REPLACEMENT OF OWNER TRUSTEE.

         The Participants, Administrative Agent and Certificate Trustee agree
that, at Lessee's sole cost and expense, if at any time the Trust Company shall
not have either a combined capital and surplus of at least $100,000,000 or have
its senior unsecured long-term debt rated at least BBB- by S&P and Baa3 by
Moody's (or shall not otherwise be guaranteed by a Person with such capital and
surplus and with such ratings), so long as no Lease Event of Default shall have
occurred and be continuing, upon Lessee's written request to take whatever
action reasonably necessary to remove and replace the Trust Company as
Certificate Trustee in accordance with the provisions of Section 4.10 of the
Trust Agreement.

         6.8      REPLACEMENT OF A CERTIFICATEHOLDER.

         Each Certificate Holder hereby agrees, at Lessee's sole cost and
expense, that if such Certificate Holder's senior unsecured long-term debt is
not rated at least BBB- by S&P or Baa3 by Moody's, then, so long as no Lease
Event of Default shall have occurred and be continuing, the Lessee may require
such Certificate Holder to transfer or assign, in whole, its Certificate in
accordance with the provisions of Section 6.3(b) to another Person with senior
unsecured long-term debt rated BBB- by S&P or Baa3 by Moody's (a "Replacement
Party") identified by the Lessee who is ready, willing and able to assume the
rights and obligations of such Certificate Holder; provided that (i) the Lessee
or such Replacement Party, shall have paid to such Certificate Holder in
immediately available funds all amounts owed to it under the Operative Documents
(including without limitation all unpaid Certificate Amounts and Yield and
amounts payable pursuant to 7.6 hereof) and (ii) such assignment does not
conflict with any Applicable Laws or Regulations of any Authority.

SECTION 7. INDEMNIFICATION

         7.1      GENERAL INDEMNIFICATION.

         (a)      General Indemnity. Lessee agrees, whether or not any of the
transactions contemplated hereby shall be consummated, to indemnify, protect,
defend, save and keep harmless on an After-Tax Basis each Indemnitee from and
against any and all Claims that may be imposed on, incurred by or asserted
against such Indemnitee in any way relating to or arising out of (a) any of the
Operative Documents or any of the transactions contemplated thereby or any
investigation, litigation or proceeding in connection therewith, and any
amendment, modification or waiver in respect thereof; or (b) any Aircraft leased
by it or any part thereof or interest therein; or (c) the acquisition,
mortgaging, design, construction, preparation, installation, inspection,
delivery, non-delivery, abandonment, acceptance, rejection, purchase, ownership,
possession, rental, lease, sublease, repossession, maintenance, repair,
alteration, modification, addition or substitution, storage, transfer of title,
redelivery, use, financing, refinancing, operation, condition, sale (including,
without limitation, any sale or other transfer pursuant to Sections 21, 22 or 23
of the Lease), return or other disposition of all or any part of any interest in
any Aircraft leased by it or the imposition of any Lien (or incurring of any
liability to refund or pay over any amount as a result of any Lien) thereon,
including, without limitation: (i) Claims or penalties arising from any
violation of law or in tort (strict liability or otherwise), (ii) any defect in
any Aircraft arising from the material or any articles used therein or from the
design, testing or use thereof or from any maintenance, service, repair,
overhaul or testing of such Aircraft, (iii) latent or other defects, whether or
not discoverable, (iv) any Environmental Claims arising from or relating to the
construction, use, operation, ownership, maintenance, leasing or redelivery or
other transfer of any Aircraft leased by it, (v) the manufacturing of the
Aircraft leased by it, and (vi) any Claim for patent, trademark or copyright
infringement relating to the Aircraft leased by it; (d) the offer, issuance,
sale, transfer, conversion or delivery of the Notes or Certificates whether
pursuant to Operative Documents or otherwise; (e) the breach by Lessee of any
representation or warranty made by it or deemed made by it in any Operative
Document; (f) the transactions contemplated hereby or by any other Operative
Document, in respect of the application of Parts 4 and 5 of Subtitle B of Title
I of ERISA and any prohibited transaction described in Section 4975(c) of the
Code, or (g) any other agreement entered into or assumed by Lessee or its
Affiliates in connection with the Aircraft. Notwithstanding the foregoing
provisions of this Section 7.1(a), Lessee shall not be obligated to indemnify an
Indemnitee under this Section 7.1(a) for any Claim to the extent that it is
attributable to any of the following: (i) Taxes, loss of tax benefits and the
cost and expense of tax controversies (whether or not indemnified by Lessee
under Section 7.2), other than a payment necessary to make payments under this
Section 7.1(a) on an After-Tax Basis; provided, that the exclusion set forth in
this clause (i) does not apply to any taxes or penalties included in Claims
against which the Indemnitee is provided an indemnification under clause (f) of
this Section 7.1(a); (ii) the gross negligence or willful misconduct of such
Indemnitee or its Affiliates; (iii) the breach by such Indemnitee of its
representations and warranties in any Operative Document as the case may be, or
the breach by an Indemnitee of its covenants in any Operative Document; (iv)
without limiting any other provision of the Operative Documents, a Claim for
which the obligation of Lessee to indemnify such Indemnitee otherwise is
determined pursuant to another provision of this Agreement or any other
Operative Document; (v) a Certificate Trustee Lien attributable to such
Indemnitee; or (vi) a Claim that has been incurred by such Indemnitee because it
has engaged in

                                       37
<PAGE>

transactions or activities other than those contemplated by this Agreement or
any other Operative Document and such Claim would be imposed even if such
Indemnitee had not engaged in the transactions or activities contemplated by
this Agreement or any other Operative Document.

         (b)      Contests. In respect of the indemnification provided under
Section 7.1(a), promptly after receipt by an Indemnitee of notice of any pending
or threatened Claim, such Indemnitee shall, if a claim in respect thereof is to
be made against Lessee by such Indemnitee, give notice thereof to Lessee. So
long as no Lease Event of Default is continuing, the Lessee, at its own expense,
may elect to assume the defense of any such Claim through its own counsel, which
shall be subject to the reasonable approval of the Administrative Agent, on
behalf of the Indemnitee (with full right of subrogation to the Indemnitee's
rights and defenses). Notwithstanding any of the foregoing to the contrary, the
Lessee shall not be entitled to assume the defense of any Claim if such
proceedings in the good faith opinion of the Indemnitee could entail any risk of
criminal liability or unindemnified civil liability. Lessee shall indicate its
election to assume such defense by written notice to the Indemnitee; provided
that prior to Lessee's assuming such defense Lessee shall acknowledge in writing
to such Indemnitee its obligation to fully indemnify such Indemnitee for such
Claim by written notice to the Indemnitee within 30 days following receipt of
Indemnitee's notice of the Claim, or in the case of a third party claim which
requires a shorter time for response then within such shorter period. If Lessee
admits liability but elects not to assume the defense thereof, such Indemnitee
shall defend such Claim (with Lessee paying the reasonable cost of such
defense). If Lessee denies liability or fails to respond to the notice within
the time period set forth above, the Indemnitee may defend or compromise the
Claim as it deems appropriate without prejudice to any of Indemnitee's rights
hereunder and with no further obligation to inform Lessee of the status of the
Claim (unless requested in writing as to the then status of such Claim) and no
right of Lessee to approve or disapprove any actions taken in connection
therewith by the Indemnitee. If Lessee shall have elected to assume the defense
of any such Claim, then upon the request of Lessee, the Indemnitee requesting
payment of indemnity under Section 7.1(a) shall promptly furnish Lessee with
copies of any records or documents pertaining to the matter to be indemnified
and, to the extent known by such Indemnitee, a reasonably detailed explanation
of the circumstances giving rise to the claim of indemnification and the
determination of the amount of the requested indemnity payment. Upon payment in
full to Indemnitee of any indemnity pursuant to Section 7.1(a), the Lessee shall
be subrogated to any right of Indemnitee in respect of the matter against which
such indemnity has been paid. If Lessee shall have elected to assume the defense
of any such Claim, upon the written request at any time and from time to time of
Lessee, Indemnitee shall, at the expense of Lessee, take such reasonable actions
and execute such documents as are necessary or reasonably appropriate to assist
Lessee in the preservation and enforcement against third parties of Lessee's
right of subrogation hereunder. The Indemnitee may employ separate counsel in
any such Claim in which Lessee shall have elected to assume the defense and
participate in the defense thereof, but the fees and expenses of such counsel
shall be at the expense of the Indemnitee unless the Indemnitee shall have been
advised in writing by its counsel that there exists a conflict of interest in
such counsel's representation of the Indemnitee and Lessee. All fees and
expenses of such contests shall be paid periodically as incurred. Lessee shall
not, without the prior written consent (not to be unreasonably withheld) of the
Indemnitee, effect any settlement of any such Claim unless such settlement
includes an unconditional release of the Indemnitee from all liabilities that
are the subject of such Claim. The parties agree to cooperate in any defense or
settlement of any such Claim and to give each other reasonable access to all

                                       38
<PAGE>

information relevant thereto subject to appropriate confidentiality agreements.
The parties will similarly cooperate in the prosecution of any claim or lawsuit
against any third party.

         7.2      GENERAL TAX INDEMNITY.

         (a)      Tax Indemnity. Lessee, on written demand, shall indemnify and
hold each Indemnitee harmless from and against, on an After-Tax Basis, any and
all Taxes, that are imposed, on or with respect to such Indemnitee, by the
United States or by any state or local government or other taxing authority in
the United States, or by any taxing authority outside the United States, in
connection with or in any way relating to: (i) the manufacture, acquisition,
mortgaging, design, construction, preparation, installation, inspection,
delivery, non-delivery, transport, location, acceptance, rejection, purchase,
ownership, possession, rental, lease, sublease, repossession, maintenance,
repair, alteration, modification, addition, substitution, storage, transfer of
title, redelivery, use, financing, refinancing, operation, condition, purchase,
repurchase, sale, return, abandonment, importation, exportation or other
application or disposition of all or any part of any Aircraft leased by it or
the imposition of any Lien (or incurrence of any liability to refund or pay over
any amount as a result of any Lien) thereon, (ii) Basic Rent or Supplemental
Rent or the hire, receipts, income or earnings arising from or received with
respect to any Aircraft or any part thereof leased by it, or any interest
therein or any applications or dispositions thereof, (iii) any other amount paid
or payable pursuant to the Certificates, the Notes or any other Operative
Documents, the property or the income or other proceeds with respect to the
property held in the Trust Estate, (iv) any Aircraft or any part thereof leased
by it or any interest therein, (v) all or any of the Operative Documents, any
other documents contemplated thereby and any amendments and supplements thereto,
and (vi) otherwise with respect to or in connection with the transactions
contemplated by the Operative Documents or the enforcement thereof; provided,
however, that the indemnification obligation of this Section 7.2(a) shall not
apply to: (1) Taxes (including franchise taxes) in respect of the overall net
income or capital gains of an Indemnitee (other than Taxes imposed on the
Certificate Trustee, the Trust or the Trust Estate) imposed by (x) any
governmental or taxing authority of the jurisdiction in which such Indemnitee is
organized and, in the case of a Lender, the jurisdiction in which its LIBOR
Office is located or (y) any other governmental or taxing authority; provided,
however, that in the case of Taxes imposed by a government or taxing authority
not described in clause (x), such Taxes shall not be excluded from the
indemnification obligation of this Section 7.2(a) to the extent that such Taxes
would have been imposed had (A) the location, possession or use of any Aircraft,
any Airframe, or any Related Engine in, the location or the operation of the
Lessee or any use of any Aircraft, any Airframe or any Related Engine in, or the
making of payments under the Operative Documents from, the jurisdiction imposing
such Taxes and/or (B) the activities of any one or more of the Indemnitees in
the jurisdiction imposing the Taxes in connection with its or their enforcement
of remedies under the Operative Documents, been the sole connection between such
Indemnitee and the jurisdiction imposing such Taxes; provided further, that this
clause (1) shall not be interpreted to prevent a payment from being made on an
After-Tax Basis if such payment is otherwise required to be so made; (2) Taxes
that result from (x) a voluntary transfer, assignment, participation or other
voluntary disposition by the Indemnitee or any of its Affiliates of all or any
portion of its interest in any Aircraft, any Airframe, any Related Engine, any
Collateral, the Trust Estate, any Indemnitee, the Certificates or the Operative
Documents (other than a transfer or disposition resulting from (A) an
Indemnitee's exercise of remedies under the Lease during the occurrence

                                       39
<PAGE>

and continuation of a Lease Event of Default, (B) Lessee's exercise of the Sale
Option or Purchase Option under the Lease, (C) any other transfer to Lessee or
its Affiliates under the Operative Documents, or (D) any transfer made at the
request of the Lessee) or (y) an involuntary transfer, any participation or
other involuntary disposition by the Indemnitee or any of its Affiliates of all
or any part of an interest in any Aircraft, any Airframe, any Related Engine,
the Trust Estate, any Indemnitee, the Certificates or the Operative Documents
(other than any such transfer or disposition that occurs while a Lease Event of
Default has occurred and is continuing) in connection with any bankruptcy or
other proceeding for the relief of debtors in which an Indemnitee or any of its
Affiliates is the debtor or any foreclosure by a creditor of an Indemnitee or
any of its Affiliates that is in each case unrelated to the transactions
contemplated by the Operative Documents; (3) Taxes (other than those to the
extent necessary to make a payment on an After-Tax Basis) imposed on or against
or payable by such Indemnitee to the extent of the excess of such Taxes over the
amount of such Taxes that would have been imposed and indemnified hereunder had
there not been a transfer by the original Indemnitee (from which such Indemnitee
derives its interest) of any interest in any Aircraft, any Airframe, any Related
Engine, the Certificates, the Trust Estate, any Indemnitee or the Operative
Documents, unless such transferee acquired its interest during the occurrence
and continuation of a Lease Event of Default or as the result of the
substitution of the Certificate Trustee or unless the transfer of such interest
to such transferee was made at the request of Lessee; (4) Taxes imposed with
respect to any period (except during the occurrence and continuance of a Lease
Event of Default) after the expiration or earlier termination of the Lease (but
not to the extent attributable to events occurring on or prior to such date);
(5) Taxes resulting from (x) the gross negligence, willful misconduct or fraud
of the Indemnitee or any of its Affiliates or (y) the inaccuracy or breach of a
representation or warranty or covenant of such Indemnitee under the Operative
Documents (unless such inaccuracy or breach is caused by Lessee's breach of any
representation, warranty or covenant under the Operative Documents); (6) Taxes
that would not have been imposed had such Indemnitee complied with the
requirements of Section 7.3; and (7) any interest, penalties or additions to Tax
that result from the failure of an Indemnitee to file any return properly and
timely, unless such failure is caused by the failure of Lessee to fulfill its
obligations, if any, under this Agreement with respect to such return.

         (b)      Contests. Lessee shall pay on or before the time or times
prescribed by law any Taxes that Lessee is liable for hereunder. If any claim or
claims is or are made against any Indemnitee for any Tax which is subject to
indemnification as provided in Section 7.2(a), Indemnitee shall as soon as
practicable, but in no event more than 30 days after receipt of formal written
notice of the Tax or proposed Tax, notify the Lessee. If requested by Lessee in
writing within 30 days of Lessee's receipt of such notice from the Indemnitee,
such Indemnitee shall contest (including all judicial appeals other than to the
United States Supreme Court), at the expense of Lessee, in the name of such
Indemnitee (or such Indemnitee, in its sole discretion, may require Lessee, if
permitted by Applicable Laws and Regulations, to contest in the name of Lessee
or such Indemnitee) the validity, applicability or amount of such Tax; provided
that such contest shall be required only if (i) in the reasonable opinion of
Lessee and its tax counsel reasonably acceptable to such Indemnitee, there
exists a reasonable basis, within the meaning of ABA Formal Opinion No. 85-352,
to contest such Tax, (ii) no Lease Event of Default has occurred and is
continuing, (iii) Lessee has acknowledged in writing its liability for the Tax
at issue to the extent the contest is not successful, (iv) the contest will not
result in a risk of criminal liability of an Indemnitee or a material risk of
sale, loss or forfeiture of the Aircraft or any part

                                       40
<PAGE>

thereof or interest therein, (v) the amount of the Tax exceeds $25,000, and (vi)
Lessee pays all reasonable expenses incurred by the Indemnitee in contesting any
such Tax (including, without limitation, all reasonable attorneys' and
accountants' fees), upon demand by the Indemnitee. Lessee shall have the right
to participate in the conduct of any proceedings controlled by the Indemnitee to
the extent that such participation by such Person does not interfere with the
Indemnitee's control of such contest and Lessee shall in all events be kept
informed, to the extent practicable, of material developments relative to such
proceedings. The Indemnitee shall have the right to participate in the conduct
of any proceedings controlled by Lessee to the extent that such participation by
such Person does not interfere with Lessee's control of such contest, and the
Indemnitee shall in all events be kept informed, to the extent practicable, of
material developments relative to such proceedings. The Indemnitees agree that a
contested claim for which Lessee would be required to make a reimbursement
payment hereunder will not be settled or compromised without Lessee's good faith
prior written consent unless the Indemnitee waives its right to indemnification
hereunder and repays the Taxes advanced by Lessee as a non-interest bearing loan
by Lessee to such Indemnitee (as provided below) with interest at the Overdue
Rate from the date of payment until receipt thereof by Lessee. Indemnitee shall
endeavor to settle or compromise any such contested claim in accordance with
written instructions received from the Lessee; provided, that (x) Lessee on or
before the date the Indemnitee executes a settlement or compromise pays the
contested Tax to the extent agreed upon or makes an indemnification payment to
the Indemnitee in an amount acceptable to the Indemnitee; and (y) the settlement
or compromise does not, in the reasonable opinion of the Indemnitee, adversely
affect the right of the Certificate Trustee or such Indemnitee to receive Rent
or the Lease Balance or any other payment pursuant to the Operative Documents,
or involve a material risk of sale, forfeiture or loss of any Aircraft or any
interest therein. The failure of an Indemnitee to contest timely a claim against
it for any Tax which is subject to indemnification under Section 7.2(a) and for
which it has an obligation to Lessee to contest under this Section 7.2(b) in the
manner required by Applicable Laws and Regulations where Lessee has timely
requested that such Indemnitee contest such claim shall relieve Lessee of its
obligations to such Indemnitee under Section 7.2(a) with respect to such claim
only to the extent such failure results in the loss of an effective contest. If
Applicable Laws and Regulations require the payment of a contested Tax as a
condition to, or regardless of, its being contested (or if the Indemnitee
controls such contest and decides to pursue such contest by paying the Tax and
seeking a refund thereof), and Lessee chooses to contest such Tax or to direct
the Indemnitee to contest such Tax in accordance with this Section, then Lessee
shall provide the Indemnitee with the funds to pay such Tax, such provision of
funds to be deemed a non-interest bearing loan by Lessee to the Indemnitee to be
repaid by any recovery of such Tax from such contest and remaining unpaid amount
not recovered to offset Lessee's obligation to indemnify the Indemnitee for such
Tax. Lessee shall indemnify the Indemnitee on an After-Tax Basis in accordance
with Section 7.7 for and against any adverse consequences of any such
interest-free loan. In the event that the Indemnitee receives a refund (or like
adjustment) in respect of any Tax for which the Indemnitee has been reimbursed
by Lessee, the Indemnitee shall promptly remit the amount of such refund (or
like adjustment), plus any interest received thereon, to Lessee, net of all
reasonable costs and expenses incurred by such Indemnitee in connection
therewith; provided, however, that the Indemnitee shall not be required to remit
any amount pursuant to this sentence in excess of the amounts previously paid by
Lessee to, or on behalf of, such Indemnitee with respect to such Tax pursuant to
this Section 7, plus any interest received thereon; provided, further, that
Indemnitee

                                       41
<PAGE>

shall not be required to remit any amount pursuant to this sentence for so long
as a Lease Event of Default has occurred and is continuing.

         (c)      Payments. Subject to Section 7.2(b), any Tax indemnifiable
under Section 7.2(a) shall be paid by Lessee directly when due to the applicable
taxing authority if direct payment is practicable and permitted. If direct
payment to the applicable taxing authority is not permitted, is not practicable
or is otherwise not made, any amount payable to an Indemnitee pursuant to
Section 7.2(a) shall be paid within thirty days after receipt of a written
demand therefor from such Indemnitee accompanied by a written statement
describing in reasonable detail the amount so payable, but not before the date
that is five Business Days prior to the date that the relevant Taxes are due.
Any payments made pursuant to Section 7.2(a) directly to the Indemnitee entitled
thereto or Lessee, as the case may be, shall be made in immediately available
funds at such bank or to such account as specified by the payee in written
directions to the payor, or, if no such direction shall have been given, by
check of the payor payable to the order of the payee by certified mail, postage
prepaid at its address as set forth in this Participation Agreement. Upon the
request of any Indemnitee with respect to a Tax that Lessee is required to pay,
Lessee shall furnish to such Indemnitee the original or a certified copy of a
receipt for Lessee's payment of such Tax or such other evidence of payment as is
reasonably acceptable to such Indemnitee.

         (d)      Reports. If any report, return or statement is required to be
filed with respect to any Taxes that are subject to indemnification under
Section 7.2(a), Lessee shall, if Lessee is permitted by Applicable Laws and
Regulations, timely prepare and file such report, return or statement; provided,
however, that if Lessee is not permitted by Applicable Laws and Regulations to
file any such report, return or statement, Lessee will promptly so notify the
appropriate Indemnitee, in which case the Indemnitee, at Lessee's expense, will
file any such report after preparation thereof by Lessee.

         (e)      Calculation of Payments. If an Indemnitee or any Affiliate of
such Indemnitee who files any tax return on a combined, consolidated, unitary or
similar basis with such Indemnitee shall actually realize any saving of any Tax
(net of any related Tax detriment) not indemnifiable by Lessee pursuant to the
Operative Documents (by way of credit (including any foreign tax credit),
deduction, exclusion from income or otherwise) by reason of any amount with
respect to which Lessee has indemnified such Indemnitee pursuant to this Section
7.2, and such net Tax saving was not taken into account in determining the
amount payable by Lessee on account of such indemnification, such Indemnitee
shall pay to Lessee, so long as no Lease Event of Default shall have occurred
and be continuing (but shall be required to make such payment at such time as
the Lease Event of Default shall have been cured) within 10 days after such
Indemnitee shall have actually realized such net Tax saving, the amount of such
saving, together with the amount of any net Tax saving resulting from any
payment pursuant to this sentence (provided that such payments by such
Indemnitee shall not exceed the amount of the payments made by Lessee to or for
such Indemnitee which gave rise to such savings and payment by such Indemnitee).

         (f)      Refund. If an Indemnitee shall receive a refund of (or receive
a credit against or any other current reduction in, any Tax not indemnified or
paid by Lessee under this Section 7.2, in respect of) all or part of any Taxes
which Lessee shall have paid on behalf of such Indemnitee or for which Lessee
shall have reimbursed, advanced funds to or indemnified such Indemnitee

                                       42
<PAGE>

(or would have received such a refund, credit or reduction but for a
counterclaim or other claim not indemnified by Lessee hereunder (a "deemed
refund")), within 10 days of such receipt (or, in the case of a deemed refund,
within 30 days of the final determination of such deemed refund), such
Indemnitee shall pay or repay to Lessee an amount equal to the amount of such
refund or deemed refund, plus any net tax benefit (taking into account any Taxes
incurred by such Indemnitee by reason of the receipt of such refund, credit or
reduction or deemed refund) realized by such Indemnitee as a result of any
payment by such Indemnitee made pursuant to this sentence (provided that such
payments by such Indemnitee shall not exceed the amount of the payments made by
Lessee to or for such Indemnitee which gave rise to such refund and payment by
such Indemnitee). If, in addition to such refund, credit or reduction or deemed
refund, as the case may be, such Indemnitee shall receive (or would have
received but for a counterclaim or other claim not indemnified by Lessee
hereunder) an amount representing interest on the amount of such refund, credit
or reduction, or deemed refund, as the case may be, such Indemnitee shall pay to
Lessee within 10 days of such receipt or, in the case of a deemed refund, within
10 days of the final determination of such deemed refund, that proportion of
such interest that shall be fairly attributable to Taxes paid, reimbursed or
advanced by Lessee prior to the receipt of such refund or deemed refund.
Notwithstanding the foregoing, such Indemnitee shall not be required to make any
payment to Lessee under this Section 7.2(f) so long as a Lease Event of Default
shall have occurred and be continuing (but shall be required to make such
payment at such time as the Lease Event of Default shall have been cured).

         (g)      Non-Parties. If an Indemnitee is not a party to this
Agreement, the Lessee may require the Indemnitee to agree in writing, in a form
reasonably acceptable to Lessee, to the terms of this Section 7.2 prior to
making any payment to such Indemnitee under this Section 7.2.

         (h)      Verification. The results of all computations required under
this Section 7.2, together with a statement describing in reasonable detail the
manner in which such computations were made, shall be delivered to the Lessee in
writing. If Lessee so requests within 30 days after receipt of such
computations, any determination shall be reviewed by a nationally recognized
independent public accounting firm mutually acceptable to the relevant
Indemnitee and the Lessee, who shall be asked to verify, after consulting with
Lessee and the relevant Indemnitee whether the relevant Indemnitee's
computations are correct, and to report its conclusions to both Lessee and the
relevant Indemnitee. Subject to satisfactory confidentiality agreements, the
relevant Indemnitee and Lessee hereby agree to provide such accountants with all
information and materials as shall be reasonably necessary or desirable in
connection herewith. The fees of the accountants in verifying an adjustment
pursuant to this Section 7.2 shall be paid by the Lessee, unless such
verification discloses an error adverse to Lessee in an amount greater than 10%
of the amount of the indemnity payment as determined by the accounting firm, in
which case such fees shall be paid by the relevant Indemnitee. Any information
provided to such accountants by any Person shall be and remain the exclusive
property of such Person and shall be deemed by the parties to be (and the
accountants will confirm in writing that they will treat such information as)
the private, proprietary and confidential property of such Person, and no Person
other than such Person and the accountants shall be entitled thereto, and all
such materials shall be returned to such Person. Such accounting firm shall be
requested to make its determination within 30 days of the Lessee's request to
such accounting firm for review. In the event such independent public accounting
firm shall determine that such computations are incorrect, then such firm shall
determine what it believes to be the correct computations. The computations of

                                       43
<PAGE>

the independent public accounting firm shall be final, binding and conclusive
upon, the Lessee and the relevant Indemnitee and Lessee shall not have any right
to inspect the books, records, tax returns or other documents of or relating to
the relevant Indemnitee to verify such computations or for any other purpose.
The parties hereby agree that the independent public accounting firm's sole
responsibility shall be to verify the computation of any amounts payable under
this Section 7.2 and that matters of interpretation of this Agreement and the
other Operative Documents are not within the scope of such independent public
accounting firm's responsibilities.

         (i)      Restructuring For Withholding Taxes. Each party covered by
this Section 7.2 agrees to use reasonable efforts to investigate alternatives
for reducing any withholding Taxes that are indemnified against hereunder or
imposed on Rent (whether or not indemnifiable hereunder) and to use reasonable
efforts to reduce any withholding Taxes that are indemnified against hereunder,
but no Party shall be obligated to take any such action as such Party determines
in its sole discretion will be adverse to its business or financial or
commercial interests.

         7.3      WITHHOLDING TAXES EXEMPTION.

         If any Participant or any assignee of, or Sub-Participant in, any Note
or Certificate (each such assignee or Sub-Participant, a "Transferee") is
organized under the laws of any jurisdiction other than the United States or any
State thereof, then such Participant or Transferee, as applicable, shall (as a
condition precedent to acquiring or participating in any Loan or Certificate and
as a continuing obligation to Certificate Trustee and Lessee) (i) furnish to
Certificate Trustee, the CP Lender, the Agents and Lessee in duplicate, for each
taxable year of such Participant or Transferee during the Term, a properly
completed and executed copy of either Internal Revenue Service Form 4224 or
Internal Revenue Service Form 1001 and Internal Revenue Service Form W-8 or
Internal Revenue Service Form W-9 and any additional form (or such other form)
as is necessary to claim complete exemption from United States withholding taxes
on all payments hereunder, and (ii) provide to Certificate Trustee, the Agents
and Lessee a new Internal Revenue Service Form 4224 or Internal Revenue Service
Form 1001 and Internal Revenue Service Form W-8 or Internal Revenue Service Form
W-9 and any such additional form (or any successor form or forms) upon the
expiration or obsolescence of any previously delivered form and comparable
statements in accordance with applicable United States laws and regulations and
amendments duly executed and completed by such Participant or Transferee, and to
comply from time to time with all applicable United States laws and regulations
with regard to such withholding tax exemption. By its acceptance of a
participation or assignment of a Participant's Note or Certificate, each
Transferee shall be deemed bound by the provisions set forth in Sections 6.3,
6.4 and this Section 7.3. No Participant or Transferee that fails to comply with
the requirements of this Section 7.3 shall be entitled to the benefit of any tax
indemnity for gross-up of payments in respect of withholding taxes pursuant to
Section 7.2 .

                                       44
<PAGE>

         7.4      LIBO RATE ILLEGAL, UNAVAILABLE OR IMPRACTICABLE.

         (a)      If any Participant shall determine in good faith (which
determination shall, upon notice thereof to Lessee, be conclusive and binding on
Lessee) that

                  (i)      a change after the Closing Date in any Governmental
         Requirement or the interpretation thereof by any governmental
         authority, court, bureau or agency charged with the administration or
         interpretation thereof (whether or not having the force of law) makes
         it unlawful, or the applicable central bank or other applicable
         Authority asserts that it is unlawful, for such Participant or its
         principal bank Affiliate to make, continue or maintain any amount of
         such Participant's investment in the Notes or Certificates on a LIBO
         Rate basis, or

                  (ii)     deposits in Dollars (in the applicable amounts) are
         not being offered to such Participant or its principal bank Affiliate
         in the relevant market for the applicable Payment Period, or that, by
         reason of circumstances affecting the interbank eurodollar market,
         adequate and reasonable means do not exist for ascertaining the
         applicable LIBO Rate, or

         (b)      If the Administrative Agent determines in good faith (which
determination shall, upon notice thereof to Lessee, be conclusive and binding
upon Lessee) that the LIBO Rate, as determined by the Administrative Agent, will
not adequately and fairly reflect the cost to any Participant or its principal
bank Affiliate of maintaining or funding its investments for the applicable
Payment Period, or that the making or funding of such Participant's investment
hereunder on a LIBO Rate basis has become impracticable as a result of an event
occurring after the date hereof which in the opinion of such Participant
materially changes such investment, or

         (c)      If an Event of Default shall have occurred and be continuing,
then the obligations of such Participant to make, continue or maintain any such
investment in the Notes or Certificates on a LIBO Rate basis shall, upon such
determination (and with respect to 7.4(a) and (b) above, upon notice thereof to
Lessee), forthwith be suspended until such Participant shall notify Lessee that
such circumstances no longer exist, and all Interest and Yield included in Basic
Rent (and Interest and Yield) allocable to such Participant shall automatically
be determined on a Reference Rate basis (plus any applicable basis points)
beginning on the next immediately succeeding Payment Date with respect thereto
or sooner, if required by such law, assertion or determination.

         (d)      As used herein, "Reference Rate" shall mean, for any day, the
higher of: (i) 0.50% per annum above the latest Federal Funds Rate; or (ii) the
rate of interest in effect for such day as publicly announced from time to time
by Bank of America, as its "reference rate." (The "reference rate" is a rate set
by Bank of America based upon various factors including Bank of America's costs
and desired return, general economic conditions and other factors, and is used
as a reference point for pricing some loans, which may be priced at, above or
below such announced rate.) Any change in the reference rate announced by Bank
of America shall take effect at the opening of business on the day specified in
the public announcement of such change.

         7.5      INCREASED COSTS.

         From and after the Closing Date, without duplication of any amounts
otherwise payable under the Operative Documents, Lessee agrees to reimburse each
Participant, within ten days after receipt of written notice from such party,
for any increase in its cost or decrease in its effective rate of return
incurred after the Closing Date (which shall include, but not be limited to,
taxes (other than income or similar taxes), fees, charges or reserves) directly
or indirectly resulting from the making of any Funding to or for the benefit of
Lessee or maintaining of its Commitment, and arising as a result of:

         (a)      any change after the Closing Date in any Governmental
Requirement or the interpretation thereof by any governmental authority, court,
bureau or agency charged with the administration or interpretation thereof
(whether or not having the force of law); or

         (b)      any capital or similar requirements imposed on any Participant
or any corporation controlling any such party against assets or liabilities (or
against any class thereof or any required change in the amount thereof) of, or
commitments or extensions of credit by, any such party (including, without
limitation, any such party's obligation to make Fundings hereunder).

Such reimbursement shall be made to the applicable Participant within ten days
after the receipt by Lessee of notice from such party setting forth the nature
and amount of such loss, decrease in its effective rate of return, or expense
and an explanation as to how such amounts were calculated by such party, said
notice to be conclusive and binding in the absence of manifest error. Lessee
will pay all amounts required pursuant to this Section 7.5 to the applicable
Participant in immediately available funds. Notwithstanding the foregoing
provisions of this Section 7.5, if any Participant fails to notify Lessee of any
event or circumstance which will entitle such Participant to compensation
pursuant to this Section 7.5 within 60 days of such Participant obtaining
knowledge of such event or circumstance, then such Participant shall not be
entitled to compensation from Lessee for any amount arising prior to the date
which is 60 days before the date on which such Participant notifies Lessee of
such event or circumstance.

         7.6      FUNDING LOSSES.

         Lessee shall pay to Certificate Trustee, as Supplemental Rent, such
amounts as may be necessary to reimburse any Participant for any loss or expense
(including, without limitation, any administration costs) incurred (i) by reason
of the liquidation or reemployment of deposits or other funds acquired by such
Participant to make, continue or maintain any portion of its investment in any
Note or Certificate on a LIBO Rate or CP Rate basis or (ii) as a result of any
payment of all or any portion of the Lease Balance for any reason on a date
other than a Payment Date, including, without limitation, by reason of
acceleration (the amount of such loss or expense is called the "Break Funding
Amount"). Any Participant shall promptly notify Certificate Trustee and
Administrative Agent in writing of the amount of any claim under this Section
7.6, the reason or reasons therefor and the additional amount required fully to
compensate such Participant for such loss or expense. Such written notice (which
shall include calculations in reasonable detail) shall, in the absence of
manifest error, be conclusive and binding on Lessee.

         7.7      Intentionally Omitted.

         7.8      FUNDING OFFICE; SUBSTITUTION OF CERTIFICATE HOLDER AND
                  FACILITY LENDER.

         (a)      If Lessee is required to pay additional amounts to or for the
account of any Participant pursuant to Sections 7.4 or 7.5, to the extent
applicable, then such Participant will agree to use reasonable efforts to change
the jurisdiction of its Applicable Lending Office so as to eliminate or reduce
any such additional payment which may thereafter accrue if such change, in the
sole judgment of such Participant, is not otherwise disadvantageous to such
Participant.

         (b)      Upon receipt by Lessee from any Certificate Holder or Facility
Lender of a claim for compensation under Section 7.5 or a notice of the type
described in Sections 7.4(a), 7.4(b) or 7.6 Lessee may arrange for one or more
banks satisfying the requirements set forth in Section 6.3 for an assignee of
such Certificate Holder or Facility Lender, as the case may be, to acquire and
assume all or a ratable part of all of such affected Certificate Holder's or
Facility Lender's Certificate Amount or Loans, respectively; provided however,
that any designation of a replacement Certificate Holder or Facility Lender, as
the case may be, shall be subject to the prior written consent of the
Administrative Agent (which consent shall not be unreasonably withheld).

         7.9      AIRCRAFT

         In the event that (a) Lessee elects the Sale Option with respect to any
Aircraft; and (b) after paying to Certificate Trustee, for the benefit of the
Participants, any amounts due under Section 23 of the Lease, the Lease Balance
for such Aircraft shall not have been reduced to zero, then Lessee shall
promptly pay over to Certificate Trustee on the Expiration Date for such
Aircraft the shortfall unless Lessee delivers a report from an appraiser
selected by the Required Participants in form and substance reasonably
satisfactory to the Required Participants and using approved methods
substantially the same as those used in the Appraisal to the Required
Participants which establishes that the reasons for the actual Fair Market Value
of such Aircraft as of the Expiration Date being less than the Fair Market Value
of such Aircraft anticipated for such date in the Appraisal delivered pursuant
to Section 4.1(i) was not due to any of the following events, circumstances or
conditions, whether or not permitted under the Lease: (i) the failure to
maintain such Aircraft as required by the Lease and the other Operative
Documents, and in at least the condition required under Section 6 of the Lease;
(ii) the carrying out of any modification and Improvements or the failure to
undertake any Required Alterations whether or not permitted pursuant to the

Agreement and the other Operative Documents,

                                       47

and each such Participant irrevocably authorizes Administrative Agent, in such
capacity, to take such action on its behalf under the provisions of this
Participation Agreement and the other Operative Documents and to exercise such
powers and perform such duties as are expressly delegated to Administrative
Agent by the terms of this Participation Agreement and the other Operative
Documents, together with such other powers as are reasonably incidental thereto.
Notwithstanding any provision to the contrary elsewhere in this Participation
Agreement, Administrative Agent shall not have any duties or responsibilities,
except those expressly set forth herein and in the other Operative Documents, or
any fiduciary relationship with any Participant or any other party to the
Operative Documents, and no implied covenants, functions, responsibilities,
duties, obligations or liabilities shall be read into this Participation
Agreement or any other Operative Document or otherwise exist against
Administrative Agent.

         8.2      DELEGATION OF DUTIES.

         Administrative Agent may execute any of its duties under this
Participation Agreement and the other Operative Documents by or through agents
or attorneys-in-fact and shall be entitled to advice of counsel concerning all
matters pertaining to such duties. Administrative Agent shall not be responsible
for the negligence or misconduct of any agents or attorneys-in-fact selected by
it with reasonable care.

         8.3      EXCULPATORY PROVISIONS.

         Neither Administrative Agent (in its capacity as such) nor any of its
officers, directors, employees, agents, attorneys-in-fact or Affiliates shall be
(a) liable for any action lawfully taken or omitted to be taken by it or such
Person under or in connection with this Participation Agreement or any other
Operative Document, except for its or such Person's own willful misconduct or
gross negligence (or negligence in the handling of funds) or (b) responsible in
any manner to any of the Participants or any other party to the Operative
Documents for any recitals, statements, representations or warranties made by
Certificate Trustee or Lessee or any officer thereof contained in this
Participation Agreement or any other Operative Document or in any certificate,
report, statement or other document referred to or provided for in, or received
by Administrative Agent under or in connection with, this Participation
Agreement or any other Operative Document, or for the value, validity,
effectiveness, genuineness, enforceability or sufficiency of this Participation
Agreement or any other Operative Document or for any failure of Certificate
Trustee or Lessee to perform its obligations hereunder or thereunder.
Administrative Agent shall not be under any obligation to any Lender or any
other party to the Operative Documents to ascertain or to inquire as to the
observance or performance of any of the agreements contained in, or conditions
of, this Participation Agreement or any other Operative Document, or to inspect
the properties, books or records of Certificate Trustee or Lessee.

         8.4      RELIANCE BY ADMINISTRATIVE AGENT.

         Administrative Agent shall be entitled to rely, and shall be fully
protected in relying, upon any Note, Certificate, writing, resolution, notice,
consent, certificate, affidavit, letter, facsimile message, statement, order or
other document or other written communication believed by it in good faith to be
genuine and correct and to have been signed, sent or made by the proper Person
or Persons and upon advice and statements of legal counsel (including counsel to

                                       48
<PAGE>

Certificate Trustee or Lessee), independent accountants and other experts
selected by Administrative Agent. Administrative Agent may deem and treat the
payee of any Note or Certificate as the owner thereof for all purposes unless a
written notice of assignment, negotiation or transfer thereof shall have been
filed with Administrative Agent. Administrative Agent shall be fully justified
in failing or refusing to take any action under this Participation Agreement or
any other Operative Document unless it shall first receive the advice or
concurrence of the Required Participants, or it shall first be indemnified to
its satisfaction by the applicable Participants against any and all liability
and expense which may be incurred by it by reason of taking or continuing to
take any such action. Administrative Agent shall in all cases be fully protected
in acting, or in refraining from acting, under this Participation Agreement and
the other Operative Documents in accordance with a request of the Required
Participants, and such request and any action taken or failure to act pursuant
thereto shall be binding upon all the Participants and all future holders of the
applicable Notes or Certificates. Subject to the provisions of Section 9.5,
wherever in the Operative Documents the consent or approval of Administrative
Agent is required, such consent or approval may be given by Administrative Agent
only upon its receipt of such consent or approval from the Required
Participants.

         8.5      NOTICE OF DEFAULT.

         Administrative Agent shall not be deemed to have knowledge or notice of
the occurrence of any Default or Event of Default unless Administrative Agent
has received notice from a Participant or Certificate Trustee referring to this
Participation Agreement, describing such Default or Event of Default and stating
that such notice is a "notice of default". In the event that Administrative
Agent receives such a notice, Administrative Agent shall promptly give notice
thereof to the Participants, Certificate Trustee and Lessee. Administrative
Agent shall take such action with respect to such Default or Event of Default as
shall be directed by the Required Participants; provided, however, that unless
and until Administrative Agent shall have received such directions,
Administrative Agent may (but shall not be obligated to) take such action, or
refrain from taking such action, with respect to such Default or Event of
Default as it shall deem advisable in the best interests of the Participants.

         8.6      NON-RELIANCE ON ADMINISTRATIVE AGENT AND OTHER LENDERS.

         Each Participant expressly acknowledges that neither Administrative
Agent, Administrator nor the Arranger, nor any of their respective officers,
directors, employees, agents, attorneys-in-fact or Affiliates, has made any
representations or warranties to it and that no act by Administrative Agent,
Administrator or the Arranger hereinafter taken, including any review of the
affairs of Certificate Trustee or Lessee, shall be deemed to constitute any
representation or warranty by Administrative Agent, Administrator or the
Arranger to any Participant. Each Participant represents to Administrative
Agent, Administrator and the Arranger that it has, independently and without
reliance upon Administrative Agent, Administrator, the Arranger or any other
Participant, and based on such documents and information as it has deemed
appropriate, made its own appraisal of and investigation into the business,
operations, property, financial and other condition and creditworthiness of
Certificate Trustee and Lessee and made its own decision to enter into this
Participation Agreement. Each Participant also represents that it will,
independently and without reliance upon Administrative Agent, Administrator, the
Arranger or any other Participant, and based on such documents and information
as it shall deem

                                       49
<PAGE>

appropriate at the time, continue to make its own credit analysis, appraisals
and decisions in taking or not taking action under this Participation Agreement
and the other Operative Documents, and to make such investigation as it deems
necessary to inform itself as to the business, operations, property, financial
and other condition and creditworthiness of Certificate Trustee and Lessee.
Except for notices, reports and other documents expressly required to be
furnished to the Participants by Administrative Agent hereunder, neither
Administrative Agent, Administrator nor the Arranger shall have any duty or
responsibility to provide any Participant with any credit or other information
concerning the business, operations, property, condition (financial or
otherwise), prospects or creditworthiness of Certificate Trustee or Lessee which
may come into the possession of Administrative Agent, Administrator, the
Arranger or any of their respective officers, directors, employees, agents,
attorneys-in-fact or Affiliates.

         8.7      INDEMNIFICATION.

         Administrative Agent agrees to look solely to Lessee under Section 7
hereof, and not to any other party hereto, for any claim for indemnification
which may arise hereunder or under any other Operative Document.

         8.8      ADMINISTRATIVE AGENT IN ITS INDIVIDUAL CAPACITY.

         Each Participant acknowledges that First Security Trust is acting as
Administrative Agent hereunder. First Security Trust and its Affiliates may make
loans to, issue letters of credit for the account of, accept deposits from,
acquire equity interests in and generally engage in any kind of banking, trust,
financial advisory, underwriting or other business with Certificate Trustee,
Lessee and their Affiliates as though it was not Administrative Agent hereunder
and under the other Operative Documents and without notice to or consent of the
Participants. Each Participant acknowledges that, pursuant to such activities,
First Security Trust or its Affiliates may receive information regarding Lessee,
Certificate Trustee or their Affiliates (including information that may be
subject to confidentiality obligations in favor of Lessee, Certificate Trustee
or their Affiliates) and acknowledges that such Persons shall be under no
obligation to provide such information to them.

         8.9      SUCCESSOR ADMINISTRATIVE AGENT.

         Subject to the appointment and acceptance of a successor Administrative
Agent as provided below, Administrative Agent may resign at any time by giving
notice thereof to each Participant and Lessee or may be removed at any time by
written notice from the Required Participants, such resignation or removal to be
effective only upon appointment of a successor as herein provided and such
successor's acceptance of such appointment. Upon any such resignation or
removal, the Required Participants at the time of the resignation or removal
shall have the right to appoint a successor Administrative Agent which shall be
a commercial bank organized under the laws of the United States of America or
any State thereof or under the laws of another country which is doing business
in the United States of America that is reasonably acceptable to Lessee (other
than during the occurrence and continuation of a Significant Default or a Lease
Event of Default) and that has a combined capital, surplus and undivided profits
of at least $500,000,000. If, within 30 calendar days after the retiring
Administrative Agent's giving of notice of resignation or receipt of a written
notice of removal, a successor Administrative

                                       50
<PAGE>

Agent is not so appointed and does not accept such appointment, then the
retiring or removed Administrative Agent may appoint a successor Administrative
Agent and transfer to such successor Administrative Agent all rights and
obligations of the retiring Administrative Agent. Such successor Administrative
Agent shall be a commercial bank organized under the laws of the United States
of America or any State thereof or under the laws of another country which is
doing business in the United States of America that is reasonably acceptable to
Lessee (other than during the occurrence and continuation of a Significant
Default or a Lease Event of Default) and that has a combined capital, surplus
and undivided profits of at least $500,000,000. Upon the acceptance of any
appointment as Administrative Agent hereunder by a successor Administrative
Agent, such successor Administrative Agent shall thereupon succeed to and become
vested with all the rights, powers, privileges and duties of the retiring or
removed Administrative Agent, and the term "Administrative Agent" shall mean
such successor agent effective upon such appointment and approval, and the
retiring or removed Administrative Agent shall be discharged from duties and
obligations as Administrative Agent thereafter arising hereunder and under any
related document without any other or further act or deed on the part of such
former Administrative Agent or any of the parties to this Participation
Agreement or any holders of the Notes or the Certificates. If the retiring
Administrative Agent does not appoint a successor, Lessee may do so, or any
Participant shall be entitled to apply to a court of competent jurisdiction for
such appointment, and in any such case the successor so appointed shall act
until such time, if any, as a successor shall have been appointed as above
provided. After any retiring Administrative Agent's resignation as
Administrative Agent, all of the provisions of this Section 8 shall inure to its
benefit as to any actions taken or omitted to be taken by it while it was
Administrative Agent under this Participation Agreement and the other Operative
Documents.

SECTION 9. MISCELLANEOUS
