accordance with Section 2.4(f). The failure of any Lender to make its ratable
portion of any Loan as required hereunder shall not relieve any other Lender of
its obligations to make its ratable portion of such Loan or any other Loan as
required hereunder.

          SECTION 2.3 SCHEDULED REPAYMENT OF THE LOANS. The Borrowers shall
repay the Loans on the dates and in the amounts set forth below by paying such

          SECTION 2.4 EVIDENCE OF DEBT; USE OF PROCEEDS.

               (a) Each Lender shall maintain in accordance with its usual
practice an account or accounts evidencing such Lender's portion of the Loans
outstanding from time to time, including, by Tranche, the amounts of principal
and interest payable and paid to such Lender from time to time under this
Agreement.

               (b) The Loan Agent shall establish and maintain a Register on
behalf of the Borrowers pursuant to Section 2.4(e), and a subaccount for each
Lender therein, in which shall be recorded (i) the amount of each Loan hereunder
and each Interest Period applicable thereto; (ii) the amount of any principal or
interest due and payable or to become due and payable from the Borrowers to each
Lender hereunder; (iii) the date and amount of each payment on the Loans, by
Tranche, made by or on behalf of, or collected from, the Borrowers and (iv) the
amount of each such payment applied in accordance with each clause of Section
2.9(d) and (e) or other applicable terms hereof to scheduled principal of or
interest on the Loans.

               (c) The entries made in the accounts maintained pursuant to
clauses (a) and (b) of this Section 2.4 shall, to the extent permitted by
applicable law, be prima facie evidence of the existence and amounts of the
obligations recorded therein; provided, however, that the failure of any Lender
or the Loan Agent to maintain such accounts or any error therein shall not in
any manner affect the obligations of the Borrowers to repay the Loans in
accordance with the terms hereof.

               (d) The Borrowers shall execute and deliver to the Loan Agent on
the Closing Date a single promissory note for each Tranche, each substantially
in the forms of Exhibit B, in the principal amount of the aggregate Commitments
for such Tranche dated the Closing Date and otherwise appropriately completed
(each such note, including any replacement note therefor issued in accordance
with the provisions of this Section 2.4(d) but excluding any note so replaced, a
"Note"). Promptly following each Loan on each Funding Date, each Lender shall
update the grid attached to its Note and



                                                                              26


deliver a certified copy thereof to the Borrowers. If a Note is mutilated, lost,
stolen or destroyed, the Borrowers shall, at the cost and expense of the Lender,
issue a new Note in the same principal amount and having the same interest rate,
date, maturity and Tranche as the Note so mutilated, lost, stolen or destroyed,
endorsed to indicate all payments thereon, together with an Officer's
Certificate of the Borrowers certifying and warranting as to the due
authorization, execution and delivery of the new Note. In the case of any lost,
stolen or destroyed Note, there shall first be furnished (i) to the Borrowers,
at Borrowers' option, either adequate security to hold Borrowers harmless with
respect to such lost, mutilated, stolen or destroyed Note or an instrument of
indemnity from the relevant Lender and (ii) to the Borrowers and the Loan Agent
evidence of such loss, theft or destruction reasonably satisfactory to each of
them.

               (e) The Notes are registered instruments. The original of each
Note shall be evidence of the rights of each Lender under this Agreement and
such Note. Neither this Agreement nor any Note is a bearer instrument. The Loan
Agent will establish and maintain on behalf of the Borrowers a record of
ownership (the "Register") in which the Loan Agent agrees to register by book
entry the Loan Agent's and each Lender's interest in the Loans, the Notes and
this Agreement, and in the right to receive any payments hereunder or thereunder
and any assignment of any such interest or rights. In connection with any
assignment pursuant to Section 9.2, the Loan Agent shall maintain a copy of each
Assignment and Assumption delivered to and accepted by it and shall record the
names and addresses of the Lenders and principal amount of the Loans, by
Tranche, owing to each Lender from time to time. The Borrowers, upon request and
at the expense of the relevant Lender and the return of the Note to be replaced
to the Borrowers marked "cancelled" (or, if the Note to be replaced has been
mutilated, lost, stolen or destroyed, adequate security or an instrument of
indemnity as described in the last sentence of Section 2.4(d)), agree to issue
replacement Notes upon any assignment or participation made pursuant to Section
9.2. The identities of the Note holders entered in the Register shall be
conclusive and binding for all purposes, absent manifest error, and the
Obligors, the Loan Agent and the Lenders shall treat each Person whose name is
recorded in the Register as the owner of the Obligations as indicated in the
Register for all purposes of this Agreement. The Register shall be available for
inspection by the Borrowers, the Loan Agent, or any Lender at any reasonable
time and from time to time upon reasonable prior notice.

               (f) Use of Proceeds.

                    (i) The Borrowers shall use the proceeds of the Loans as
     follows:

                         (1) The proceeds of Tranche A Loans, Tranche D Loans,
     and Tranche E Loans shall be used by the Borrowers for working capital and
     general corporate purposes of either of them, including, without
     limitation, capital expenditures and acquisitions.

                         (2) The proceeds of Tranche B Loans shall be used by
     the Borrowers solely to make debt service payments due through June,



                                                                              27


     2006 under the A321 Airbus Financings or to reimburse US Airways for any
     such payments made on or after the date of the MOU (May 18, 2005) but prior
     to the date of such Loan.

                         (3) The proceeds of Tranche C Loans shall be used by
     the Borrowers solely to pay, or to reimburse either of them for the payment
     on or after the date of the MOU (May 18, 2005) of, Permitted Invoices.

                    (ii) No portion of the proceeds of any Loans shall be used
     by the Borrowers or any of their Subsidiaries in any manner that would
     cause the borrowing or the application of such proceeds to violate
     Regulation U, Regulation T or Regulation X of the Board of Governors of the
     Federal Reserve System or any other regulation of such Board of Governors
     or to violate Section 7(c) of the Exchange Act, in each case as in effect
     on the date or dates of such borrowing and such use of proceeds.

          SECTION 2.5 OPTIONAL PREPAYMENTS.

               (a) The Borrowers may on any Business Day, upon revocable notice
to the Loan Agent not less than ten (10) Business Days prior thereto, prepay all
or any portion of the outstanding principal amount of such Loans held directly
or indirectly by Airbus or its Affiliates, in whole or in part (but, with
respect to any partial prepayment, not less than a minimum amount of $1,000,000,
plus any whole multiple of $100,000, or such lesser amount as results in a
prepayment of such Loans in full), together with accrued interest to the date of
such prepayment on the principal amount prepaid; provided, however, that if any
prepayment of all or a portion of such Loans is made by the Borrowers other than
on an Interest Payment Date, the Borrowers shall also pay any amounts owing
pursuant to Section 2.10(e). Except for any such amounts owing pursuant to
Section 2.10(e), prepayments pursuant to this Section 2.5(a) shall be without
premium or penalty.

               (b) Upon the giving of any notice of prepayment under clause (a)
of this Section 2.5, the principal amount of the Loans specified to be prepaid
together with accrued and unpaid interest thereon and other amounts, if any, due
with respect thereto as provided in Section 2.5(a), shall become due and payable
on the date specified for such prepayment; provided, however, that any failure
to make any such prepayment in full on such date shall be deemed to be an
automatic revocation of the notice of prepayment given under Section 2.5(a) and
such failure shall not constitute a Default or an Event of Default hereunder;
provided, further, however, that the Borrowers shall be obligated to pay on such
date any amounts owing under Section 2.10(e) due to such failure to prepay.

               (c) Any partial prepayment of the Loans under Section 2.5(a)
shall be applied pro rata as among the outstanding Tranches of the Loans held
directly or indirectly by Airbus or its Affiliates and pro rata among the Loans
in each such Tranche, and to the then remaining installments of the outstanding
principal amount of the Loans



                                                                              28


held, directly or indirectly, by Airbus or its Affiliates on a pro rata basis.
Any such prepayment shall be paid to the Loan Agent for application as provided
in Section 2.9. The Borrowers shall have no right to optionally prepay the
principal amount of the Loans held, directly or indirectly, by Airbus or its
Affiliates other than as provided in this Section 2.5 and Section 2.10, 2.12 or
9.1.

               (d) The Borrowers shall have the same prepayment rights with
respect to Loans not held, directly or indirectly, by Airbus or its Affiliates
as set forth above in this Section 2.5; provided, however, that if requested by
the Initial Lender in connection with a transfer or sell down transaction into
the capital markets as envisioned in Section 9.2(e), the Borrowers shall have
such prepayment rights as are determined as provided in Section 9.2(c).

          SECTION 2.6 MANDATORY PREPAYMENTS.

               (a) Collateral Sales. Upon receipt by any Borrower or any
Subsidiary of Net Cash Proceeds of an Asset Sale of any Collateral (including
without limitation, any Airbus A321 model aircraft then subject to an A321
Airbus Financing). The Borrowers shall prepay the Loans and any other
Obligations then due in an aggregate amount equal to the Net Cash Proceeds of
such sale, provided that no such prepayment shall be required for Asset Sales of
Spare Parts until the aggregate amount thereof (not applied to prior
prepayments) exceeds $100,000. In the event that any such Asset Sale results in
a note payable to any Borrower or any Subsidiary, such note shall be pledged by
such Borrower or Subsidiary, as the case may be, as collateral security for the
obligations and the Cross-Default Obligations in a manner reasonably
satisfactory to the Loan Agent. Any partial prepayments of the Loans made by the
Borrowers in accordance with this Section 2.6(a) shall be applied pro rata as
among the outstanding Tranches of the Loans and pro rata among the Loans in each
such Tranche and to the then remaining installments of the outstanding principal
balance of the Loan on a pro rata basis. If any such prepayment is made by the
Borrowers other than on an Interest Payment Date, subject to clause (c) below,
the Borrowers shall also pay any amounts owing pursuant to Section 2.10(e). Any
such prepayment of the Loan shall be paid to the Loan Agent for application as
provided in Section 2.9.

               (b) Insurance/Condemnation Proceeds. No later than three Business
Days following the date of receipt by the Borrowers or any of their Subsidiaries
of any Net Insurance Proceeds of any Collateral, except as provided in Section
3.04(a) of the Engine Mortgage and Security Agreement if an Engine (as defined
therein) is being replaced, in Section 6.01(a) of any Aircraft Mortgage, if an
Aircraft or Airframe is being replaced, and in Section 3.05(d)(1) of the Spare
Parts Mortgage and Security Agreement, if a Spare Part is being replaced, the
Borrower shall prepay the Loans and any other Obligations then due in an amount
equal to the amount of such Net Insurance Proceeds; provided that no such
prepayment shall be required until the aggregate amount thereof (not applied to
prior prepayments) exceeds $100,000; and provided, further that in the case of a
prepayment required by Section 3.04(a) of the Engine Mortgage and Security
Agreement or Section 6.01(a) of any Aircraft Mortgage on a date before the date
on which Net Insurance Proceeds has been received, such prepayment of the Loans
in the



                                                                              29


amount specified in the next sentence hereof, and on the date specified in such
Senior Mortgage, shall be made in lieu of the prepayment out of the Net
Insurance Proceeds required by this sentence. The amount to be prepaid pursuant
to the proviso to the preceding sentence shall be the Agreed Value (as defined
in the applicable Senior Mortgage) minus the applicable prepayment amount under
such applicable Senior Mortgage. Any partial prepayments of the Loans made by
the Borrowers in accordance with this Section 2.6(b) shall be applied pro rata
as among the outstanding Tranches of the Loans and pro rata among the Loans in
each such Tranche and to the then remaining installments of the outstanding
principal balance of the Loan on a pro rata basis. If any such prepayment is
made by the Borrowers other than on an Interest Payment Date, subject to clause
(c) below the Borrowers shall also pay any amounts owing pursuant to Sections
2.5(d) and 2.10(e). Any such prepayment of the Loans shall be paid to the Loan
Agent for application as provided in Section 2.9.

               (c) Notwithstanding the foregoing, if no Default or Event of
Default has occurred and is continuing, the Borrower shall be entitled to
postpone the date of prepayment under Section 2.6(a) or (b) as follows. At least
one (1) Business Day prior to the required date of such prepayment, Borrower
shall notify the Loan Agent and each Lender of its election to postpone the date
of such prepayment to the next succeeding Interest Payment Date and on the date
required for such prepayment the Borrower shall pay to the Loan Agent, for
deposit in a collateral account established with the Loan Agent and under its
name and sole dominion and control, as security for the Obligations and the
Cross-Default Obligations, an amount equal to the amounts the Borrower would
have paid under Section 2.6(a) or (b), as the case may be, as a prepayment of
the Loans and any other Obligations on such date. The Loan shall remain
outstanding and on the next succeeding Interest Payment Date the Borrower shall
pay the installment of interest and principal and any other amounts then due,
plus the amount required to prepay the Loan in whole or in part on such Interest
Payment Date (calculated as provided in Section 2.6(a) or (b), as the case may
be, less the amount available to the Loan Agent (out of the funds held by it as
aforesaid as collateral security) which shall be applied in reduction of the
Borrower's obligations on such Interest Payment Date. Notwithstanding the
foregoing, if an Event of Default shall occur and be continuing, funds on
deposit in the aforesaid collateral account shall be subject to distribution
under Section 2.9(d) and the provisions of Section 6.2 shall not be prejudiced
by the foregoing prepayment arrangement.

          SECTION 2.7 INTEREST.

               (a) Rate of Interest. Except as otherwise provided in Section
2.7(c) and Section 2.10, each Loan shall bear interest on the unpaid principal
amount thereof for each day such Loan is outstanding during any Interest Period
at the Applicable Interest Rate for such Interest Period. Notwithstanding any
other provision hereof, interest on the Loans shall not exceed the maximum
allowable under applicable law.

               (b) Interest Payments. Interest accrued on each Loan and each
Note shall be payable in arrears on the last day of each applicable Interest
Period (an "Interest Payment Date"), upon the payment or prepayment thereof in
whole or in part



                                                                              30


(solely to the extent of the portion paid or prepaid), and, if not previously
paid in full, at maturity (whether by acceleration or otherwise). Interest on
each Loan shall be calculated on the basis of a year of 360 days and actual
number of days elapsed.

               (c) Default Interest. Notwithstanding the rate of interest
specified in Section 2.7(a) or elsewhere herein, if any principal of or interest
on a Loan or any fee or other amount payable by the Borrowers hereunder is not
paid when due, whether at stated maturity, upon acceleration, by mandatory
prepayment or otherwise (but other than any voluntary prepayment), such overdue
amount shall bear interest at a rate which is two percent per annum in excess of
the Applicable Interest Rate as in effect from time to time.

          SECTION 2.8 FEES. No up-front, commitment or other fees are payable on
or with respect to the Commitments or the Loans.

          SECTION 2.9 PAYMENTS AND COMPUTATIONS.

               (a) The Borrowers shall make each payment hereunder (including
fees and expenses) not later than 12 noon (New York City time) on the day when
due, in Dollars, to the Loan Agent in immediately available funds without
set-off, counterclaim, claim of recoupment or other defense (except for any
required withholding taxes not subject to indemnification hereunder) to the
following account (unless otherwise advised):

          ACCOUNT OF : AIRBUS FINANCIAL SERVICES
          ACCOUNT AT : CALYON, NEW YORK
          SWIFT CODE : CRLYUS33
          CHIPS ID   : 807
          ABA REF    : 026 008 073
          ACCOUNT NO : 01 22456 0001 00

All payments in respect of any Obligations shall at all times be made to the
Loan Agent. The Loan Agent will promptly cause all such payments received by it
to be distributed to the Person entitled thereto in accordance with the
priorities of payment set forth below in clause (d) or (e) of this Section 2.9
or both, as applicable. Payments received by the Loan Agent after 2:00 p.m. (New
York City time) shall, solely for the calculation and accrual of interest
pursuant to the provisions hereof, be deemed to be received on the next Business
Day.

               (b) Each determination by the Loan Agent of an interest rate
hereunder shall be presumed correct, absent manifest error.

               (c) Whenever any payment hereunder shall be stated to be due on a
day other than a Business Day, such payment shall be due on the next succeeding
Business Day, unless the result of such extension would be to extend such
payment date into another calendar month, in which event such payment date shall
end on the immediately preceding Business Day and for the avoidance of doubt,
interest computation shall be adjusted accordingly.



                                                                              31


               (d) So long as no Event of Default under any of Sections 6.1(a)
(including any failure to pay all amounts hereunder upon acceleration as a
result of any other Event of Default), (f) and (g) has occurred and is
continuing or would result therefrom, the Loan Agent shall promptly apply all
payments received by it in respect of any Obligations in the following order:

                    (i) first, to pay interest then due and payable in respect
     of the Loans to the Lenders, on a pro rata basis;

                    (ii) second, to pay principal then due and payable on the
     Loans to the Lenders, on a pro rata basis;

                    (iii) third, to pay any other Obligations then due and
     payable to the Loan Agent, the Collateral Agent and the Lenders, on a pro
     rata basis; and

                    (iv) fourth, to the Borrowers or their respective designees.

               (e) After the occurrence and during the continuance of an Event
of Default under any of Sections 6.1(a) (including any failure to pay all
amounts hereunder upon acceleration as a result of any other Event of Default),
(f) or (g), the Loan Agent shall promptly apply all payments in respect of any
Obligations or Cross-Default Obligations (including amounts received by the
Collateral Agent upon the exercise of remedies with respect to the Collateral or
the Cross-Collateral) in the following order:

                    (i) first, to pay Obligations in respect of any expenses,
     indemnities or other amounts owing hereunder not referred to in clauses
     (ii) through (v) below then due and payable to the Lenders, the Loan Agent
     or the Collateral Agent, on a pro rata basis;

                    (ii) second, to pay interest then due and payable in respect
     of the Loans to the Lenders, on a pro rata basis;

                    (iii) third, to pay or prepay principal payments on the
     Loans to the Lenders or other Obligations to the respective parties
     entitled thereto, on a pro rata basis, or to be held by, the Loan Agent as
     additional collateral for any Obligations which are not at the time due and
     payable;

                    (iv) fourth, to pay any Cross-Default Obligations then due
     and payable to the respective parties entitled thereto, on a pro rata
     basis, or to be held by the Loan Agent as Collateral for any Cross-Default
     Obligations which are not at the time due and payable; and

                    (v) fifth, after payment in full of the Cross-Default
     Obligations, to the Borrowers or their respective designees.



                                                                              32


          SECTION 2.10 CERTAIN PROVISIONS GOVERNING THE LOANS.

               (a) Certain Determinations. LIBOR for each Interest Period for
each Loan shall be determined by the Loan Agent pursuant to the procedures set
forth in the definition of "LIBOR"; the Applicable Margin shall be adjusted as
provided in the definition of "Applicable Margin"; and shall promptly thereafter
be notified to the Borrowers and each Lender together, in the case of a
determination of "LIBOR", with the Applicable Margin and the Applicable Interest
Rate for such Interest Period (in writing or by email or by telephone confirmed
in writing or by email). The Tranche A, Tranche B, Tranche C, Tranche D and
Tranche E Commitment Reduction Amounts for the Lenders (and for each Lender)
shall be determined by the Loan Agent as provided in the respective definitions
of those terms and, together with the amount of the reduced Tranche A, Tranche
B, Tranche C, Tranche D and Tranche E Commitments of the Lenders (and of each
Lender), promptly notified to each Lender, the Borrower, and the Collateral
Agent and the Loan Agent (as defined in the Other Loan Agreement). The aggregate
amount of the Tranche A, Tranche B, Tranche C, Tranche D and Tranche E
Commitment Reduction Amounts for the Lenders shall not exceed $89,000,000. A
certificate of the Loan Agent setting forth the applicable LIBOR, the Applicable
Margin and the adjusted Applicable Interest Rate, or the Tranche A, Tranche B,
Tranche C, Tranche D or Tranche E Commitment Reduction Amounts, shall be
presumed correct absent manifest error. The Loan Agent shall, at the request of
either Borrower, deliver to the Borrowers a statement showing the quotations
used by the Loan Agent to determine LIBOR, the Applicable Margin and the
Applicable Interest Rate, such statement to be in sufficient detail for the
Borrowers to reasonably determine whether any such manifest error has occurred.

               (b) Interest Rate Unascertainable. In the event that the Loan
Agent determines that, at the time the Loan Agent is to determine the Applicable
Interest Rate for an Interest Period, by reason of circumstances affecting the
London interbank market for U.S. Dollar deposits, adequate and fair means do not
exist for ascertaining the applicable interest rates by reference to which the
LIBOR then being determined is to be fixed, the Loan Agent shall forthwith so
notify the Borrowers and the Lenders, whereupon during the 30 days following the
date of any such notice given to the Borrowers, the Loan Agent and the Borrowers
shall negotiate in good faith in order to arrive at a mutually acceptable
alternative basis for determining the interest rate from time to time applicable
to the Loans (the "Substitute Basis"). If within the 30 days following the date
of any such notice to the Borrowers, the Loan Agent and the Borrowers shall
agree upon a Substitute Basis, such Substitute Basis shall be retroactive to and
effective from the first day of the then current Interest Period until and
including the last day of such Interest Period. If after 30 days from the date
of such notice, the Loan Agent and the Borrowers shall have failed to agree upon
a Substitute Basis, then the Loan Agent (upon instructions from the Requisite
Lenders) shall certify in writing to the Borrowers the interest rate at which
such Lenders are prepared to maintain their portion of the Loans for such
Interest Period, it being understood that such Lenders' interest rate shall be
not more than a rate per annum equal to a rate which adequately and fairly
reflects the cost to such Lenders of obtaining the funds necessary to maintain
their portion of the Loans for such Interest Period. If no Substitute Basis is
established, upon



                                                                              33


receipt of notice of the interest rates at which the Requisite Lenders are
prepared to maintain their respective portion of the Loans, and on the last day
of each Interest Period thereafter, the Borrowers shall have the right
exercisable upon ten Business Days' prior notice to the Loan Agent (i) to
continue to borrow the Loans at the interest rate so advised by the Loan Agent
(as such rate may be modified, from time to time, at the outset of each
subsequent Interest Period) or (ii) to prepay in full the Loans together with
accrued but unpaid interest thereon at the Applicable Interest Rate most
recently in effect, whereupon the Loans shall become due and payable on the date
specified by the Borrowers in such notice.

               (c) Increased Costs. If at any time (i) the introduction after
the date hereof of or any change after the date hereof in or in the
interpretation of any law, treaty or governmental rule, regulation or order
binding on any Lender or (ii) the compliance by any Lender with any guideline,
request or directive enacted or imposed or made after the date hereof from any
central bank or other Governmental Authority (whether or not having the force of
law) shall (A) impose, modify, or deem applicable any reserve, special deposit
or similar requirement against assets of, deposits with or for the account of,
or credit extended by, any Lender, or (ii) impose on any Lender any other
condition, and the result of any of the foregoing shall be to materially
increase the cost to such Lender of agreeing to make or making, funding, or
maintaining any portion of the Loans (except with respect to Excluded Taxes),
then the Borrowers shall from time to time, within ten Business Days of written
demand (which demand shall be accompanied by a certificate setting forth the
basis for such demand and a calculation of the amount thereof in reasonable
detail) by such Lender (with a copy of such demand and certificate to the Loan
Agent), pay to the Loan Agent for the account of such Lender, additional amounts
sufficient to compensate such Lender for such increased cost. Such a certificate
submitted to the Borrowers and the Loan Agent by such Lender shall be
presumptively correct absent manifest error. Notwithstanding the provisions of
this paragraph, (x) the Borrowers shall not be obligated to pay any amounts
pursuant to this paragraph for periods occurring prior to the 60th day before
the giving of such certificate, provided that if the circumstances giving rise
to such claim have a retroactive effect then such 60 day period shall be
extended to then include such period of retroactive effect, and (y) the
Borrowers shall not be required to make any payment otherwise required hereby to
any Lender unless such Lender states in its written demand that such claim is
not being made on a basis that discriminates against the Borrower as compared to
comparable extensions of credit with similarly situated borrowers.

               (d) Illegality. Notwithstanding any other provision of this
Agreement, if the introduction of or any change in or in the interpretation of
any law, treaty or governmental rule, regulation or order, in each case after
the date of this Agreement, shall make it unlawful for any Lender to continue to
fund or maintain its portion of the Loans as contemplated hereby, then, on
notice thereof by such Lender to the Borrowers through the Loan Agent, the
obligation of such Lender to continue to fund or maintain its portion of the
Loan shall be terminated and the Borrowers shall prepay such affected portion of
the Loan to such Lender together with accrued but unpaid interest thereon and
all other sums payable hereunder with respect thereto on the last day of the
then current Interest Period or earlier if necessary to avoid such illegality.
Any



                                                                              34


such partial prepayment of the Loan shall be applied ratably to the then unpaid
installments thereof in accordance with the amount of each such unpaid
installment.

               (e) Breakage Costs. In addition to all amounts required to be
paid by the Borrowers pursuant to Section 2.7, the Borrowers shall compensate
each Lender, at the time specified herein, or if no such time is specified,
within ten Business Days of written demand (with a copy of such demand to the
Loan Agent), for all net losses, expenses and liabilities (including any loss or
expense incurred by reason of the liquidation or reemployment of deposits or
other funds acquired by such Lender or the termination of any other financial
arrangement it may have entered into to fund or maintain or support such
Lender's portion of the Loan, including any net loss of interest but excluding
any other lost profit or any Taxes based on the overall net income of such
Lender) which such Lender actually sustains as a consequence of (i) any proposed
Borrowing not occurring on a date specified therefor in any Notice of Borrowing
given by any Borrower, (ii) any portion of the Loans being prepaid (including,
subject to Section 2.6(c), mandatorily pursuant to Section 2.6 or this Section
2.10) on a date which is not the last day of the applicable Interest Period, or
(iii) any failure by any Borrower to repay any portion of the Loans when
required by the terms hereof (after giving effect to any grace periods). Any
written demand by a Lender under this Section 2.10(e) shall be accompanied by a
certificate setting forth the basis for such demand and a calculation of the
amount thereof in reasonable detail by such Lender. Such a certificate submitted
to the Borrowers and the Loan Agent by a Lender shall be presumptively correct
absent manifest error. Amounts paid under this Section 2.10(e) shall be paid to
the Loan Agent for the account of the applicable Lender. Notwithstanding the
provisions of this paragraph, the Borrowers shall not be obligated to pay any
amounts pursuant to this paragraph for periods occurring prior to the 60th day
before the giving of such certificate, provided that if the circumstances giving
rise to such claim have a retroactive effect then such 60 day period shall be
extended to then include such period of retroactive effect.

          SECTION 2.11 CAPITAL ADEQUACY. If at any time (a) the adoption of or
any change in or in the interpretation of any law, treaty or governmental rule,
regulation or order after the date of this Agreement regarding capital adequacy,
(b) compliance with any such law, treaty, rule, regulation, or order, or (c)
compliance with any guideline or request or directive made after the date hereof
from any central bank or other Governmental Authority (whether or not having the
force of law) shall have the effect of reducing the rate of return on such
Lender's (or any corporation controlling such Lender's) capital as a consequence
of its obligations hereunder (other than for changes in the rate of tax on the
overall net income of such Lender) to a level below that which such Lender or
such corporation could have achieved but for such adoption, change, compliance
or interpretation by an amount deemed by such Lender to be material, then,
within ten Business Days following written demand from time to time by such
Lender (with a copy of such demand to the Loan Agent), the Borrowers shall pay
to the Loan Agent for the account of such Lender from time to time as specified
by such Lender additional amounts sufficient to compensate such Lender for such
reduction. Any written demand by a Lender under this Section 2.11 shall be
accompanied by a certificate setting forth the basis for such demand and a
calculation of the amount thereof in reasonable detail by such Lender. Such a
certificate submitted to the Borrowers and the Loan Agent



                                                                              35


by a Lender shall be presumptively correct absent manifest error.
Notwithstanding the provisions of this paragraph, (x) the Borrowers shall not be
obligated to pay any amounts pursuant to this paragraph for periods occurring
prior to the 60th day before the giving of such certificate, provided that if
the circumstances giving rise to such claim have a retroactive effect then such
60 day period shall be extended to then include such period of retroactive
effect, and (y) the Borrowers shall not be required to make any payment
otherwise required hereby to any Lender unless such Lender is generally
demanding payment under comparable provisions of its agreements with similarly
situated borrowers.

          SECTION 2.12 SUBSTITUTION OF LENDERS.

               (a) In the event that no Event of Default has occurred and is
continuing and (i) any Lender makes a claim under Section 2.10(c) or (e) or
Section 2.11, (ii) it becomes unlawful for any Lender to continue to fund or
maintain its portion of the Loans as contemplated hereby and such Lender
notifies the Borrowers pursuant to Section 2.10(d), (iii) any Obligor is
required to make any payment pursuant to Section 2.13 that is attributable to a
particular Lender, (iv) any Lender fails to fund any Loans as required hereby or
(v) there shall exist a Non-Consenting Lender in respect of a Proposed Change to
which the Loan Agent consents (any such Lender, an "Affected Lender"), the
Borrowers may substitute any other Lender or any other financial institution
which will eliminate the continued need to make such payments and which is
reasonably acceptable to the Loan Agent (a "Substitute Institution") for such
Affected Lender hereunder, after delivery of a written notice (a "Substitution
Notice") by the Borrowers to the Loan Agent and the Affected Lender following
the occurrence of any of the events described in clauses (i) through (v) above
that the Borrowers intend to make such substitution.

               (b) If the Substitution Notice was properly issued under this
Section 2.12, the Affected Lender shall sell, and the Substitute Institution
shall purchase, in accordance with Section 9.2, all rights and obligations
(except with respect to prior periods) of such Affected Lender under the Loan
Documents. Such purchase and sale (and the corresponding assignment of all
rights and obligations (except with respect to prior periods) hereunder) shall
be effective on the later of (i) the receipt by the Affected Lender of an amount
equal to the unpaid principal amount, accrued interest on, and other amounts due
in respect of, its outstanding Loans, together with any other Obligations owing
to it, (ii) the receipt by the Loan Agent of an Assignment and Assumption
whereby the Substitute Institution shall agree to be bound by the terms hereof
and (iii) without duplication, the payment in full to the Affected Lender in
cash of all unreimbursed costs and expenses and indemnities accrued and unpaid
through such effective date.

               (c) If any Lender requests compensation under Section 2.10(c) or
(e), 2.11 or 2.13, or if any Borrower is required to pay any additional amount
to any Lender or any Governmental Authority for the account of any Lender
pursuant to Section 2.13, then such Lender shall use reasonable efforts to
designate a different lending office for funding or booking its Loans hereunder
or to assign its rights and obligations hereunder to another of its offices,
branches or Affiliates, if, in the judgment of such Lender, such designation or
assignment (i) would eliminate or reduce amounts payable pursuant to Section
2.10(c) or (e), 2.11 or 2.13, as the case may be, in the future



                                                                              36


and (ii) would not subject such Lender to any material unreimbursed cost or
expense and would not otherwise be disadvantageous to such Lender.

          SECTION 2.13 TAXES.

               (a) Except as otherwise provided in Section 9.2 or as required by
applicable law, any and all payments by the Borrowers under each Loan Document
shall be made free and clear of and without deduction for any and all Taxes,
excluding (i) in the case of each Lender, each Participant and the Loan Agent
taxes measured by its net income, and franchise taxes (imposed in lieu of net
income taxes) imposed on it, by the jurisdiction under the laws of which such
Lender, such Participant or the Loan Agent (as the case may be) is organized or
is otherwise treated as doing business (other than a jurisdiction in which such
Person is treated as doing business as a result of its execution and delivery of
any Loan Document or its exercise of its rights or performance of its
obligations or the receipt of income thereunder), (ii) in the case of each
Lender and each Participant, taxes measured by its net income, and franchise
taxes (imposed in lieu of net income taxes) imposed on it, by the jurisdiction
in which such Lender's Lending Office is located or in which such Participant
booked its participation for tax accounting purposes, (iii) in the case of each
Lender, each Participant, and the Loan Agent, Taxes imposed as a result of such
Person or the Loan Agent failing to comply with its obligations under Section
2.13(g), (iv) in the case of each Lender, each Participant, and the Loan Agent,
as the case may be, United States federal withholding taxes except to the extent
imposed as a result of a change in applicable law, including income tax
conventions, after the Closing Date or, with respect to an assignment,
acquisition, participation, designation of a different office or jurisdiction
for purposes of receiving or paying amounts hereunder, or the appointment of a
Loan Agent, the effective date thereof, except (x) to the extent that such
Person's predecessor was entitled to such amounts (or in the case of a
designation of a new jurisdiction, to the extent such Person was entitled to
such amounts with respect to its prior jurisdiction) or (y) in the case of an
assignment or change of lending office pursuant to Section 2.13(g), and (v)
Taxes to the extent imposed as a result of the gross negligence or willful
misconduct of the Loan Agent, such Lender or any of their Affiliates (all such
non-excluded Taxes being referred to as "Indemnified Taxes" and all Taxes listed
in clauses (i) through (v) of this clause (a) being referred to as "Excluded
Taxes"). If any Indemnified Taxes shall be required by law to be deducted from
or in respect of any sum payable under any Loan Document to any Lender or the
Loan Agent (i) the sum payable shall be increased as may be necessary so that
after making all required deductions (including deductions applicable to
additional sums payable under this Section 2.13) such Lender, or the Loan Agent
(as the case may be) receives an amount equal to the sum it would have received
had no such deductions been made, (ii) the Borrowers shall make such deductions,
and (iii) the Borrowers shall pay the full amount deducted to the relevant
taxing authority or other authority in accordance with applicable law.

               (b) In addition, the Borrowers agree to pay any present or future
stamp or documentary taxes or any other excise or property taxes, charges or
similar levies of the United States or any political subdivision thereof or any
applicable foreign jurisdiction, and all liabilities with respect thereto, which
arise from any payment



                                                                              37


made under any Loan Document or from the execution, delivery or registration of,
or otherwise with respect to, any Loan Document excluding, in each case, such
amounts that result from an assignment, grant of a participation, transfer or
designation of a new Lending Office or other office for receiving payments under
any Loan Document unless (x) the same takes place in connection with an Event of
Default (so long as such Event of Default is continuing) or at Borrower's
written request (collectively, "Other Taxes") to the Loan Agent for the account
of the affected party or (y) in the case of an assignment or change of lending
office pursuant to Section 2.13(g).

               (c) The Borrowers will indemnify each Lender and the Loan Agent
for the full amount of Indemnified Taxes or Other Taxes, without duplication,
(including any Taxes imposed by any jurisdiction on amounts payable under this
Section 2.13) paid by such Lender or the Loan Agent (as the case may be) and any
liability (including for penalties, interest and expenses) arising therefrom or
with respect thereto. This indemnification shall be made to the Loan Agent for
account of the relevant Lender or the Loan Agent, as the case may be, within 30
days from the date such Lender or the Loan Agent (as the case may be) makes
written demand therefor (with a copy to the Loan Agent if made by a Lender, and
accompanied by a statement setting forth the basis for such taxation and the
calculation of the amount thereof in reasonable detail).

               (d) Within 30 days after the date of any payment of Indemnified
Taxes or Other Taxes, the Borrowers will furnish to the Loan Agent the original
or a certified copy of a receipt evidencing payment thereof or other
documentation reasonably satisfactory to the Loan Agent.

               (e) Without prejudice to the survival of any other agreement of
the Borrowers hereunder, the agreements and obligations of the parties contained
in this Section 2.13 shall survive the payment in full of the Obligations.

               (f) Each Lender, each Participant and the Loan Agent shall, on or
prior to the Closing Date or on or prior to the date of the Assignment and
Assumption pursuant to which it becomes a Lender or on or prior to the date such
Person becomes a Participant or the Loan Agent, as applicable, and from time to
time thereafter if reasonably requested by the Loan Agent or the Borrowers,
provide the Loan Agent and the Borrowers, with two completed copies of IRS Form
W-8BEN, W-8ECI, W-8IMY, W-9 and/or other applicable forms, certificates and
documents prescribed by the IRS with respect to United States withholding and/or
backup withholding tax with respect to all payments to be made to such Person
under the Loan Documents. In addition, each Lender, each Participant and the
Loan Agent, as the case may be, shall deliver to the Borrowers and the Loan
Agent, notice of any event (other than a change in applicable law, including
income tax conventions) requiring a change in the most recent form certificates
and/or documents previously delivered by such Person to the Borrowers and the
Loan Agent and any additional, updated or changed forms, certificates or
documents. Unless the Loan Agent and the Borrowers have received forms,
certificates, and/or other documents reasonably satisfactory to them indicating
that payments under the Loan Documents to or for a Non-U.S. Person are not
subject to United States withholding tax or are subject to such tax at a rate
reduced by an applicable tax treaty, the Loan Agent or



                                                                              38


the Borrowers shall, notwithstanding the provisions of Section 2.13(a), (b) and
(d) and without impairing any obligation of the Borrowers under this Section
2.13 with respect to such tax, withhold such United States withholding taxes
from such payments at the appropriate rate.

               (g) Any Lender claiming any additional amounts payable pursuant
to this Section 2.13 shall use its reasonable efforts (consistent with its
internal policy and legal and regulatory restrictions) to change the
jurisdiction of its Lending Office if the making of such a change would avoid
the need for, or reduce the amount of, any such additional amounts which would
be payable or may thereafter accrue and would not, in the sole determination of
such Lender, be otherwise disadvantageous to such Lender.

               (h) If the Borrower or Guarantor pays any amount under this
Section 2.13 to a Lender, Participant or the Loan Agent (each, a "Tax
Indemnitee") and such Tax Indemnitee determines in its sole discretion that it
has actually realized in connection therewith a net cash benefit (including a
net cash benefit which the relevant taxing authority applies to satisfy any
liability of such Tax Indemnitee for Taxes) due to any refund or any reduction
of, or credit against, its liabilities for Taxes in any taxable year, provided
that no Event of Default shall have occurred and be continuing, such Tax
Indemnitee shall, to the extent it can do so without prejudice to the retention
of such benefit, pay to the Borrower or Guarantor (as the case may be) an amount
that the Tax Indemnitee shall, in its sole discretion, determine (subject to
confirmation as provided below) is equal to such net cash benefit which was
obtained by Tax Indemnitee in such year as a consequence of such refund,
reduction or credit realized in connection with the payment of such amount. A
Tax Indemnitee shall, upon written request from the Borrower, provide to the
Borrower a letter from independent accountants selected by the Tax Indemnitee
and reasonably acceptable to the Borrower confirming the accuracy of the
Lender's calculations of the amount of any net benefit determined by the Tax
Indemnitee pursuant to the preceding sentence, provided that the interpretation
of this Agreement or any other Loan Document shall not be within the scope of
the accountants' confirmation. Nothing contained in this Section 2.13(h) shall
be construed as requiring any Tax Indemnitee to conduct its business or arrange
or alter in any respect its Tax or financial affairs so that it is entitled to
receive a refund, reduction or credit or shall require any Tax Indemnitee to
provide to the Borrower or its agents copies of any Tax returns or other
information with respect to the income, assets or operations attesting to such
Tax Indemnitee's determination. The Borrower shall reimburse such Tax Indemnitee
for all costs and expenses incurred by such Tax Indemnitee in obtaining such
accountants' letter, provided that the accountants' letter confirms, in all
material respects, such Tax Indemnitee's determination.

               (i) Borrower shall have no obligation to pay, or indemnify any
Tax Indemnitee for, any amount under this Section 2.13 or for any United States
federal income tax or withholding tax which was required by law to be deducted
or withheld by the Borrower or the Loan Agent from any payment to or for the
benefit of such Tax Indemnitee but which was not deducted or withheld due to the
Borrower's or the Loan Agent's reasonable reliance the withholding forms,
certificates and/or documents



                                                                              39


theretofore delivered by such Tax Indemnitee or the Loan Agent pursuant to
Section 2.13(f) if such form, certificate and/or document was inaccurate in any
material respect when delivered by such Tax Indemnitee and/or the Loan Agent and
such Tax Indemnitee or the Loan Agent had Actual Knowledge of such inaccuracy at
the time such Tax Indemnitee or the Loan Agent delivered such form.

               (j) If a Tax Indemnitee receives a written claim from any taxing
authority for any Tax for which the Borrower is liable pursuant to Section 2.13
(a "Tax Claim"), such Tax Indemnitee shall promptly notify the Borrower in
writing. If requested by the Borrower in writing within 30 days after receipt of
such Tax Indemnitee's written notice (provided that if a response to such Tax
Claim is due less than 40 days after the Borrower's receipt of such Tax
Indemnitee's notice, the Borrower's request must be made within 15 days or, if
longer, the period ending not later than the 10th day before the day on which
the response to such Tax Claim is due), such Tax Indemnitee shall in good faith
contest or, at such Tax Indemnitee's election, permit the Borrower to contest
(unless such contest involves Taxes not indemnified or paid by the Borrower or
Guarantor or, in such Tax Indemnitee's reasonable, good faith judgment,
permitting the Borrower to contest may have a material adverse effect on such
Tax Indemnitee), in each case in accordance with and to the extent permitted by
applicable law and at the Borrower's expense, such Tax Claim, provided that no
Tax Indemnitee shall have any obligation to commence or continue the contest of
any such Tax Claim unless the following conditions are satisfied at the time the
contest is to be commenced and at all times during the contest:

                    (i) no Event of Default shall have occurred and be
     continuing,

                    (ii) contesting such Tax Claim would not result in (A) any
     risk of sale, forfeiture, confiscation, seizure or loss of, or the
     imposition of a Lien (other than a Lien for the Tax that is the subject of
     such contest provided that enforcement of such Lien is stayed until the
     final determination of such contest and the Borrower maintains adequate
     reserves with respect to such Lien) or (B) any risk of imposition of
     criminal liability,

                    (iii) the aggregate amount of the Taxes that are to be
     contested exceeds Twenty-Five Thousand Dollars ($25,000),

                    (iv) such Tax Indemnitee shall have received a written
     confirmation of the Borrower that the Taxes that are the subject of such
     Tax Claim are Tax for which the Borrower is liable pursuant to Section
     2.13, provided that the Borrower shall not be bound by such confirmation to
     the extent that the final determination of the contest articulates
     conclusions of law and fact that clearly demonstrate that the Taxes that
     are the subject of such Tax Claim are not Taxes for which the Borrower is
     liable pursuant to Section 2.13,



                                                                              40


                    (v) the Borrower, upon the written request of such Tax
     Indemnitee, shall have provided such Tax Indemnitee, at the expense of the
     Borrower, with an opinion of counsel selected by such Tax Indemnitee and
     reasonably acceptable to the Borrower to the effect that there is a
     substantial basis in law and fact to contest such Tax Claim and a realistic
     expectation that a contest of such Tax Claim would be successful,

                    (vi) if such Tax Indemnitee decides to contest such Tax
     Claim by paying the Taxes that are the subject of such Tax Claim and taking
     action to obtain a refund thereof, the Borrower shall have made an
     interest-free advance to such Tax Indemnitee in an amount equal to the
     amount of those Taxes and shall have delivered to such Tax Indemnitee a
     written undertaking to indemnify such Tax Indemnitee and its Affiliates on
     an after-tax basis for any adverse Tax consequences (taking into account
     all relevant Tax benefits and Tax detriments) to such Tax Indemnitee or any
     of its Affiliates resulting from such interest-free advance, and

                    (vii) the Borrower shall be paying, on demand and on an
     after-tax basis, all reasonable costs and expenses incurred by such Tax
     Indemnitee or the Loan Agent with the conduct of such contest (including,
     without limitation, reasonable attorneys' and accountants' fees and
     disbursements).

               (k) Subject to Section 9.2(c)(2), a Participant will be entitled
to the benefits and subject to the requirements of this Section 2.13 to the same
extent as if such Person were a Lender.

          SECTION 2.14 PRO RATA TREATMENT AND PAYMENTS. Each Borrowing by either
Borrower from the Lenders hereunder, and each payment by either Borrower on
account of any reduction of the Commitments of the Lenders shall be made pro
rata according to the respective Commitments of the relevant Lenders. Each
payment (including each prepayment) by either Borrower on account of principal
of and interest on or other amounts in respect of the Loans shall be made pro
rata according to the respective outstanding principal amounts of the Loans then
held by the Lenders (except as otherwise provided in Section 2.10, 2.11, 2.13 or
9.4).

                                   ARTICLE III

                    CONDITIONS TO CLOSING AND FUTURE FUNDINGS

to carry out the transactions contemplated hereby and thereby.



                                                                              46


               (b) Each Obligor is qualified to do business and in good standing
in every jurisdiction where its assets are located and wherever necessary to

49 and holds a certificate under Sections 41102 of Title 49.

               (e) The Borrowers possess all necessary franchises, licenses, and
permits necessary to authorize the Borrowers to lawfully engage in air

Effect.

          SECTION 4.2 AUTHORIZATION OF BORROWING, ETC.(a)Each Obligor has duly
authorized by all necessary corporate action the execution, delivery and
performance of the Loan Documents to which it is a party. The execution,
delivery and performance by each Obligor of the Loan Documents to which it is a

Articles of Incorporation or Bylaws of such Obligor, (C) conflict with, result
in a breach of or constitute (with due notice or lapse of time or both) a
default under any Contractual Obligation of such Obligor or any of its
Subsidiaries except to the extent of any such violation, conflict, breach,
default, or imposition of Lien (of which no Obligor has Actual Knowledge) which
could not reasonably be expected to have a Material Adverse Effect, or (D)
result in or require the creation or imposition of any Lien on any of the
Collateral (except as permitted in the applicable Collateral Document) or on any
other property (except as permitted under Section 5.13 hereof), or (ii) require
any approval of stockholders or any approval or consent of any Person under any
Contractual Obligation of such Obligor or any of its Subsidiaries, except for
such approvals or consents which will have been obtained on or before the

Obligation and the failure to obtain which could not reasonably be expected to

the Loan Documents to which it is a party and the consummation of the
transactions contemplated by the Loan Documents to which it is a party and the
use of the proceeds of the Loans do not and will not require any registration
with, consent or approval of, or notice to, or other action to, with or by, any
federal, state or other Governmental Authority or regulatory body or any other
Person which is required to be obtained or made on or prior to the Closing Date
and which has not previously been obtained or made.

               (c) Each Obligor has duly executed and delivered each of the Loan
Documents to which it is party and each such Loan Document is the legally valid
and binding obligation of such Obligor, enforceable against such Obligor in
accordance with its respective terms, except as may be limited by bankruptcy,
insolvency, reorganization, moratorium, fraudulent transfer or other similar
laws relating to or affecting the enforcement of creditors' rights generally,
including materiality, reasonableness, good faith and fair dealing, and by
general principles of equity (regardless of whether considered in a proceeding
in equity or at law).

               (d) No part of the proceeds of the Loans will be used, directly
or indirectly, for any purpose that entails a violation of Regulations U or X of

               (a) The unaudited pro forma consolidated balance sheet of the
Guarantor and its consolidated Subsidiaries for the Fiscal Years 2005 through
2008 (including the notes thereto) (the "Pro Forma Balance Sheet"), which has

the occurrence of the Effective Time (as defined in the Merger Agreement), (ii)
the Loans to be made on the Closing Date and the use of proceeds thereof and

Guarantor as at December 31, 2004 and the related consolidated statements of

prepared in conformity with GAAP and fairly present the consolidated financial
position of the applicable Obligor as at the respective dates thereof and the
consolidated results of operations and cash flows of such Obligor for each of

the Loan Agent prior to the date of this Agreement, neither Obligor has any
contingent liability or liability for taxes, long-term lease or unusual forward
or long-term commitment (A) that is not reflected in the foregoing consolidated
financial statements (or, in the case of the Borrowers, in the most recently
delivered consolidated financial statements delivered pursuant to Section 5.1)
or the notes thereto and (B) which in any such case would result in a Material
Adverse Effect.

               (c) After giving effect to the Consummation of the Plan, (i) the
Obligors taken as a whole are or were Solvent on the First Funding Date after
giving effect to the Borrowings on such date, and (ii) no Obligor has any

liability for taxes, long-term lease or any unusual forward or long-term
commitment of a type required to be reflected in financial statements prepared
in conformity with GAAP, that is not taken into account in the preparation of
the annual report on Form 10-K for the fiscal year ended December 31, 2004 of
such Reporting Obligor.

Subsidiaries have (i) good, sufficient and legal title to (in the case of fee
interests in real property), (ii) valid leasehold interests in (in the case of
leasehold interests in real or personal property), or (iii) good title to (in
the case of all other personal property), all of the properties and assets
reflected in the financial statements referred to in Section 4.3 or, in the most
recent financial statements delivered pursuant to Section 5.1, in each case
except for assets disposed of since the date of such financial statements in the
ordinary course of business or as otherwise permitted under Section 6.5. Except
as otherwise permitted by this Agreement, all such properties and assets are
free and clear of Liens.

          SECTION 4.6 LITIGATION; ADVERSE FACTS. Except as set forth in either
Borrowers' or Guarantors Annual Reports on Form 10-K for 2004, as amended
through the Closing Date, or in any Quarterly Report on Form 10-Q or Current
Report on Form 8-K filed by such Borrower or Guarantor with the SEC subsequent
to such Form 10-K (in each case, as amended through the Closing Date) and except
as disclosed in other publicly available filings of either of the Borrowers or
the Guarantor with the SEC or as disclosed in any publicly available filing with
the Bankruptcy Court in the Cases, there are no actions, suits, proceedings,
arbitrations or governmental investigations (whether or not purportedly on
behalf of any Obligor or any of its Subsidiaries) at law or in equity or before
or by any federal, state, municipal or other governmental department,
commission, board, bureau, agency or instrumentality, domestic or foreign,
pending or, to the knowledge of the Obligors, threatened against any Obligor or
any of its Subsidiaries or any property of any Obligor or any of its
Subsidiaries that, if adversely determined,



                                                                              49


would have a Material Adverse Effect or seeks to restrain or enjoin any Obligor
from entering into or performing under any Loan Document.

          SECTION 4.7 TAX RETURNS. Each Obligor and each of their respective
Subsidiaries have timely filed all Federal income tax returns and all other
material tax returns that are required to be filed by them (or extensions have
been obtained with respect thereto) and have paid all material Taxes shown to be
due pursuant to such returns or pursuant to any assessment received by such
Person, other than (i) any such assessment being contested in good faith through
appropriate proceedings and with respect to which an adequate reserve has been
established by the Obligors or their Subsidiaries to the extent required by GAAP
and (ii) that the Debtors' obligations to pay taxes that relate to a tax period
(or portion thereof) ending on or before the commencement of the Cases and which
first became due and payable after the time of the commencement of the Cases,
have been stayed or enjoined pursuant to the Plan of Reorganization, the
Confirmation Order or the Bankruptcy Code, it being understood that the
exception in clause (ii) above does not affect the Debtors' representation that
they have made adequate provision for such Taxes.

          SECTION 4.8 NO DEFAULT OR EVENT OF DEFAULT. No Default or Event of
Default has occurred and is continuing.

          SECTION 4.9 GOVERNMENTAL REGULATION. None of the Obligors is (i) an

          SECTION 4.10 EMPLOYEE BENEFIT PLANS. Within the last 6 years, each
Plan maintained, contributed to, or required to be contributed to by the
Borrowers or an ERISA Affiliate is in compliance with all applicable laws,
except to the extent failure to so comply could not be reasonably expected,
individually or in the aggregate, to have a Material Adverse Effect. Neither the
Borrowers nor any ERISA Affiliate have incurred any liability under Title IV of
ERISA within the last 6 years which remains unsatisfied nor, to the best of
their knowledge, do the Borrowers reasonably expect to incur any liability under
Title IV of ERISA, which in either event, could reasonably be expected,
individually or in the aggregate, to have a Material Adverse Effect.

          SECTION 4.11 COMPLIANCE WITH LAWS. Each Obligor and each of its
Subsidiaries is in compliance with all laws, statutes, rules, regulations and
orders binding on or applicable to such Obligor, its Subsidiaries and all of
their respective properties, except to the extent failure to so comply could not
reasonably be expected to have a Material Adverse Effect.

          SECTION 4.12 SECURITY DOCUMENTS. Each of the Borrowers has good title
to the Collateral free and clear of Liens other than Liens permitted Section
5.13 and not prohibited by the applicable Collateral Document. No Person holds
any right or interest in any of the Pledged Spare Parts under the Spare Parts
Security Agreement by virtue of any interest that such person may have in real
property or improvements at any of the



                                                                              50


Designated Locations (as defined therein). The Collateral Documents are
effective to create in favor of the Collateral Agent, for the benefit of the
Lenders, a legal, valid and enforceable security interest in the Collateral
described therein and proceeds thereof. When appropriate financing statements,
filings and recordings with the FAA, and other filings and recordings specified
on Schedule 4.12, in appropriate form are filed in the offices specified on
Schedule 4.12, the Collateral Documents shall constitute a fully perfected Lien
on, and security interest in, all right, title and interest of the Borrowers in
such Collateral and the proceeds thereof, as security for the Obligations and
the Cross-Default Obligations, in each case prior and superior in right to any
other Person (except Liens permitted by Section 5.13 and not prohibited by the
applicable Collateral Document, none of which are of record except for the Liens
of the Senior Mortgages).

          SECTION 4.13 CONCERNING THE COLLATERAL.

               (a) Section 1110. The Collateral Agent is entitled to the
benefits of Section 1110 of the Bankruptcy Code with respect to the Specified
Engines as provided in the Engine Mortgage and Security Agreement and to not
less than the Minimum 1110 Percentage (determined on the basis of Appraisal
Value as of the Closing Date) of the Rotables included within the Pledged Spare
Parts as provided in the Spare Parts Security Agreement in the event of a case
under Chapter 11 of the Bankruptcy Code in which a Borrower is a debtor. Defined
terms in this paragraph not otherwise defined herein shall have the respective
meanings specified in the Spare Parts Security Agreement.

               (b) Condition. All Pledged Spare Parts are in the condition and
state of repair required under the FAA-approved maintenance program of the

or A321 Aircraft subject to an A321 Airbus Financing, and no circumstance,
condition, act or event has then occurred that, with the giving of notice or
lapse of time or both gives rise to or constitutes an Event of Loss with respect
to any Pledged Engine, unless arrangements satisfactory to the Loan Agent have
been made for the Loan Agent to receive, out of Net Insurance Proceeds or
otherwise, the prepayment envisioned under Section 3.04(a) of the Engine
Mortgage and Security Agreement for Pledged Engines which have suffered an Event
of Loss. On each subsequent Funding Date, No Event of Loss has occurred with
respect to any Pledged Engine, or A321 Aircraft subject to an A321 Airbus
Financing, with respect to which any Obligor or any of its Subsidiaries has not
complied in all material respects with its applicable obligations under the
Collateral Documents and the documents related to the A321 Airbus Financings;
and no circumstance, condition, act or event has occurred that, with the giving
of notice or lapse of time or both gives rise to or constitutes an Event of Loss
with respect to any Pledged Engine, of which the Loan Agent has not been
notified by the Borrowers.

               (h) Outstanding Amount. On the first Funding Date, the

for the Senior Engine Mortgage).

          SECTION 4.14 REPRESENTATIONS AND WARRANTIES OF THE COLLATERAL AGENT.
The Collateral Agent represents and warrants to the other parties hereto, in its
individual capacity, on and as of the Closing Date and on each date as required
by Section 3.1, that:

               (a) Powers and Authorizations. It is a national banking
association duly organized and validly existing in good standing under the laws
of the United States and has full power and authority, in its individual
capacity, to execute and deliver this Agreement and the Collateral Documents to
which it is a party and (assuming the due authorization, execution and delivery
of this Agreement by the other parties



                                                                              52


hereto) perform its obligations thereunder. The execution, delivery and
performance by the Collateral Agent of the Loan Documents to which it is or will
be a party have been duly authorized by all necessary action on its part and do
not contravene the Charter or By-laws of the Collateral Agent; and the Loan
Documents to which the Collateral Agent is or will be a party have been duly
authorized, executed and delivered by the Collateral Agent and constitute the
legal, valid and binding obligations, enforceable against it in accordance with
its terms. This Agreement and the other Loan Documents to which the Collateral
Agent is or will be a party, upon the due execution and delivery hereof, will
constitute the legal, valid and binding obligations of the Collateral Agent in
its individual capacity, and the performance by the Collateral Agent (in its
individual or trust capacity, as the case may be) of any of its obligations
hereunder and thereunder does not contravene any federal law or regulation or
contractual restriction binding on or governing the banking or trust powers of
the Collateral Agent (in its individual or trust capacity, as the case may be);

               (b) Litigation. There are no pending (or, to the Collateral
Agent's knowledge, threatened) actions, suits, investigations or proceedings
against or affecting it before any court, arbitrator, or administrative or
governmental body which, individually or in the aggregate, if decided adversely
to the interests of the Collateral Agent would materially and adversely affect
the ability of the Collateral Agent, either in its individual capacity or as
Collateral Agent, as the case may be, to perform its obligations under this
Agreement or any other Loan Document or which questions or would affect the
legality or validity of this Agreement or such Loan Document;

               (c) No Legal Bar. Neither the execution and delivery by the
Collateral Agent of this Agreement or any other Loan Document nor the
consummation by the Collateral Agent of any of the transactions contemplated
hereby or thereby requires or will require the consent or approval of or the
giving of notice to, the registration with, or the taking of any other action in
respect of, any federal governmental authority or agency governing its banking
or trust powers.

and will cause its Subsidiaries to, pay or discharge or cause to be paid or
discharged, before the same shall become delinquent, all taxes, assessments and

improvements thereto, all as in the judgment of the Guarantor and the Borrowers
may be necessary so that the business carried on in connection therewith may be
properly and advantageously conducted at all times; provided, however, that
nothing in this Section shall prevent the Guarantor, either Borrower or any
Subsidiary from discontinuing the operation and maintenance of any such
properties if such discontinuance is, in the good faith judgment of the
Guarantor, the Borrowers or such Subsidiary, as the case may be, desirable in
the conduct of its respective business and shall not impair the ability of the
Guarantor or either Borrower to perform their payment or other material
obligations under the Loan Documents. The Guarantor and each Borrower will
insure and keep insured, and will cause each of its Subsidiaries to insure and
keep insured, with reputable insurance companies, such of their respective

cause its Subsidiaries to, permit any authorized representatives designated by
the Loan Agent to discuss its and their affairs, finances and accounts with its

Borrower's business, as reasonably determined by the Guarantor and the
Borrowers.

          SECTION 5.6 COMPLIANCE WITH LAWS, ETC. Each Obligor will, and will
cause each of its Subsidiaries to, comply with all applicable statutes, rules,
regulations, orders and restrictions of the United States of America, all states
and municipalities thereof, and of any governmental department, commission,
board, regulatory authority, bureau, agency and instrumentality of the
foregoing, in respect of the conduct of their respective businesses and the
ownership of their respective properties, except such as are being contested in
good faith by appropriate proceedings and except for such noncompliance as could
not reasonably be expected to result in a Material Adverse Effect.

          SECTION 5.7 FURTHER ASSURANCES. At any time or from time to time
following the request of the Loan Agent, the Obligors will, at their expense,
promptly execute, acknowledge and deliver such further documents and do such
other acts and things as the Loan Agent may reasonably request in order to
effect fully the purposes of the Loan Documents. From the date on which the Cape

Lenders, shall enter into such documentation, as reasonably requested by the
Loan Agent and is necessary (i) to establish "international interest(s)" under
the Cape Town Convention, (ii) to enhance the enforceability of the agreements
of the parties established under the Loan Documents under the Cape Town

Plans and Multiemployer Plans with respect to which the Obligors may have any
liability are operated in compliance with all applicable laws, except to the
extent that the failure to do so could not reasonably be expected to have a
Material Adverse Effect.

hereunder be an "air carrier" within the meaning of Title 49 and hold a
certificate under 49 U.S.C. Section 41102(a)(1) as currently in effect or as
amended or recodified from time to time. Each Borrower will at all times
hereunder hold an air carrier operating certificate issued pursuant to Chapter

pounds or more of cargo.

Lien permitted under any of clauses (b) through (e) above on any property of an
Obligor already constituting Collateral, other than pursuant to the Senior
Mortgages and the Aircraft Mortgages (and the Senior Mortgages referenced
therein).

with or into or merge with or into, or enter into another form of corporate
combination with or into, any Person, or, in one or a series of transactions,
convey, lease or transfer all or substantially all its properties and assets to
any Person, unless: (i) either (A) such Obligor, or, if the transaction involves
more than one Obligor, an Obligor, is the surviving entity, or (B) an Obligor is
not the surviving entity and such surviving entity or the Person that acquires
by conveyance, lease or transfer all or substantially all the properties and
assets of an Obligor, shall be a corporation organized and existing under the
laws of the United States of America or any State or the District of Columbia,
and shall expressly assume, by an agreement executed and delivered to the Loan
Agent, in form and substance reasonably satisfactory to the Loan Agent, all of
such Obligor's obligations under the Loan Documents; (ii) immediately before and
after giving effect to such transaction, no Event of Default or Default shall
have occurred and be continuing; and (iii) the Obligors have delivered to the
Loan Agent an Officer's Certificate and an opinion of counsel from counsel
satisfactory to the Loan Agent, in form and substance



                                                                              60


satisfactory to the Loan Agent, stating that such transaction and such agreement
comply with this Section and that all conditions precedent herein provided for
relating to such transaction have been complied with and addressing such other
matters as may be reasonably requested by the Loan Agent; provided, however,
that no such transaction or merger, consolidation, corporate combination,
conveyance, lease or transfer shall involve a manufacturer of aircraft or
airframes, or an Affiliate thereof, other than Airbus.

          SECTION 5.15 CERTAIN APPROVALS UNDER THE ATSB LOAN AGREEMENT. Neither
Borrower will give its approval or consent to a sale of any right, obligation or
interest under an ATSB Loan Agreement, or any note or loan document referred to

thereof, or (ii) involving Tranche B-1.

                                   ARTICLE VI

90 days after receipt by the Borrowers of such notice; or

               (e) (i) With respect to any Cross-Default Obligation identified

under any agreement (as amended or modified from time to time) under which any

appointment of a receiver, liquidator, sequestrator, trustee, custodian or other
officer having similar powers over any Obligor or any of its Subsidiaries, or
over all or a substantial part of its property, shall have been entered; or
there shall have occurred the involuntary appointment of an interim receiver,
trustee or other custodian of any Obligor or any of its Subsidiaries for all or
a substantial part of its property; or a warrant of attachment, execution or
similar process shall have been issued against any substantial part of the

assert, or any Lien created by any of the Collateral Documents shall cease, for
any reason other than discharge of the Lien thereof in accordance with its
terms, to be in full force and effect, to be enforceable and of the same effect
and priority purported to be created thereby; or

               (j) Any Borrower shall cease to carry and maintain, or cause to
be carried and maintained, insurance on and in respect of the Collateral in
accordance with the requirements of any applicable Collateral Document.

          SECTION 6.2 REMEDIES. During the continuance of any Event of Default,

interest and all such amounts and Obligations shall become and be immediately
due and payable, and/or declare the Commitments to be terminated, whereupon the
Commitment of each Lender shall be terminated, all without presentment, demand,
protest or further notice of any kind, all of which are hereby expressly waived
by the Borrowers; provided, however, that upon the occurrence of the Event of
Default specified in Section 6.1(f) or 6.1(g), the Loans, all such interest and

                                  ARTICLE VII

          THE LOAN AGENT AND THE COLLATERAL AGENT

          The parties hereto agree as follows:

          SECTION 7.1 AUTHORIZATION AND ACTION. Each Lender hereby appoints and
authorizes each of the Loan Agent and the Collateral Agent to take such action
as administrative agent and collateral agent, respectively, on its behalf and to
exercise such powers under this Agreement and the other Loan Documents as are
delegated by such Lender to it as Loan Agent or Collateral Agent by the terms
hereof and thereof, together with such powers as are reasonably incidental
thereto, and each of the Loan Agent and the Collateral Agent hereby accepts such
authorization and appointment. As to any matters not expressly provided for by
this Agreement and the other Loan Documents or



                                                                              63


provided for with specific reference to this Section 7.1 (including, without
limitation, enforcement or collection of any Note), neither the Loan Agent nor
the Collateral Agent shall be required to exercise any discretion or take any
action, but shall be required to act or to refrain from acting (and shall be
fully protected in so acting or refraining from action) upon the instructions of
the Requisite Lenders and such instructions shall be binding upon all Lenders;
provided, however, that neither the Loan Agent nor the Collateral Agent shall be
required to take any action which exposes either the Loan Agent or the
Collateral Agent to liability or which is contrary to this Agreement, any other
Loan Document or applicable law. As to any provisions of this Agreement under
which action may be taken or approval given by the Requisite Lenders, the action
taken or approval given by the Requisite Lenders, shall be binding upon all
Lenders to the same extent and with the same effect as if each Lender had joined
therein. Each of the Loan Agent and the Collateral Agent shall be entitled to
rely upon any note, notice, consent, certificate, affidavit, letter, telegram,
teletype message, facsimile transmission, statement, order or other document
believed by it to be genuine and correct and to have been signed or sent by the
proper person or persons and, in respect of legal matters, upon the opinion of
counsel selected by the Loan Agent or the Collateral Agent. Each of the Loan
Agent and the Collateral Agent may deem and treat the payee of the Notes as the
owner thereof for all purposes hereof unless and until a written notice of the
assignment or transfer thereof shall have been filed with the Loan Agent. Any
request, authority or consent of any Person who at the time of making such
request or giving such authority or consent is the holder of any Note shall be
conclusive and binding on any subsequent holder, transferee or assignee of such
Note. The Lenders agree and acknowledge that the Collateral Agent, in addition
to being appointed by and acting on behalf of the Lenders hereto, is also (as of
the date hereof) being appointed by and acting on behalf of the lenders party to
the Other Loan Agreement. Therefore, the Collateral Agent is an agent of and is
acting for and on behalf of all of the Lenders party hereto and, in addition,
all of the lenders party to the Other Loan Agreement.

          SECTION 7.2 AGENT'S RELIANCE, ETC. Neither the Loan Agent nor the
Collateral Agent nor any of their respective Affiliates, directors, officers,
agents or employees shall be liable to any Lender for any action taken or
omitted to be taken by it or by such directors, officers, agents or employees
under or in connection with this Agreement, the Notes or any other Loan
Document, except for its or their own gross negligence or willful misconduct.
Without limitation of the generality of the foregoing, each of the Loan Agent
and the Collateral Agent: (i) may consult with legal counsel, independent public
accountants and other experts selected by it and shall not be liable to any
Lender for any action taken or omitted to be taken in good faith by it in
accordance with the advice of such experts; (ii) makes no warranty or
representation to any Lender and shall not be responsible to any Lender for any
statements, warranties or representations (whether oral or written) made in or
in connection with this Agreement, the Notes or any other Loan Document; (iii)
shall not have any duty to ascertain or to inquire as to the performance or
observance of any of the terms, covenants or conditions of this Agreement, the
Notes or any other Loan Document on the part of Guarantor or the Borrowers or to
inspect the property (including the books and records) of Guarantor, the
Borrowers or any of their respective Subsidiaries; (iv) shall not be responsible
to any Lender for the due execution, legality, validity, enforceability,
genuineness, sufficiency



                                                                              64


or value of this Agreement, the Notes or any other Loan Document, or any other
instrument or document furnished pursuant thereto; (v) shall incur no liability
under or in respect to this Agreement, the Notes or any other Loan Document by
acting upon any notice, consent, certificate or other instrument or writing
(which may be by telegram, facsimile transmission, cable or telex) believed by
it to be genuine and signed or sent by the proper party or parties; and (vi) may
deem and treat each Lender which makes a loan hereunder as the holder of the
indebtedness resulting therefrom for all purposes hereof until the Loan Agent
receives and accepts an Assignment and Assumption entered into by such Lender,
as assignor, and an eligible assignee as provided in Section 9.2 hereof.

          SECTION 7.3 AGENT AND AFFILIATES. If and so long as the Loan Agent or
the Collateral Agent shall remain a Lender, the Loan Agent or the Collateral
Agent, as applicable, shall have the same rights and powers under this Agreement
as any other Lender and may exercise the same rights and powers under this
Agreement as any other Lender and may exercise the same as though it were not
the Loan Agent or the Collateral Agent; and the term "Lender" or "Lenders"
shall, unless otherwise expressly indicated, include the Loan Agent and the
Collateral Agent, each in its individual capacity. Unrelated to its role as Loan
Agent or Collateral Agent as set forth herein, the Loan Agent and the Collateral
Agent and their respective Affiliates may accept deposits from, lend money to,
act as trustee under indentures of, and generally engage in any kind of business
with, the Borrowers, Guarantor, any of their respective Subsidiaries and any
Person who may do business with or own securities of the Borrowers, Guarantor,
or any of their respective Subsidiaries, all as if it were not the Loan Agent or
the Collateral Agent, as applicable, hereunder and without any duty to account
therefor to the Lenders.

          SECTION 7.4 REPRESENTATIONS OF THE LENDERS. Each Lender has actively
engaged in the negotiation of all of the terms of this Agreement. Each of the
Loan Agent and the Collateral Agent has no duty or responsibility, either
initially or on a continuing basis, to provide any Lender with any credit or
other information with respect to the Borrowers whether coming into its
possession as of the date of this Agreement or at any time thereafter, or to
notify any Lender of any Event of Default except as provided in Section 7.5
hereof. This Agreement and all instruments or documents delivered in connection
with this Agreement have been reviewed and approved by each Lender and none of
the Lenders have relied on the Loan Agent or the Collateral Agent as to any
legal or factual matter in connection therewith or in connection with the
transactions contemplated thereunder.

          SECTION 7.5 EVENTS OF DEFAULT. In the event of the occurrence of any
Default or Event of Default, any Lender knowing of such event may (but shall
have no duty to) give the Loan Agent and the Collateral Agent written notice
specifying such Event of Default or other event and expressly stating that such
notice is a "notice of default". Neither the Loan Agent nor the Collateral Agent
shall be deemed to have knowledge of such events unless the Loan Agent or the
Collateral Agent, as applicable, has received such notice, or unless the Event
of Default consists of a failure of payment of principal or interest on the
Note. In the event that the Loan Agent or the Collateral Agent receives such a
notice of the occurrence of an Event of Default, the Loan Agent or the
Collateral Agent, as applicable, shall give written notice thereof to the
Lenders. The



                                                                              65


Loan Agent and the Collateral Agent shall take such action with respect to such
Default or Event of Default as shall be reasonably directed in writing by the
Requisite Lenders, provided, however, that, unless and until the Loan Agent or
the Collateral Agent shall have received such direction, the Loan Agent and the
Collateral Agent may (but shall not be obligated to) take such action, or
refrain from taking such action, with respect to such Event of Default as it
shall deem advisable and in the best interest of the Lenders.

          SECTION 7.6 LOAN AGENT'S AND COLLATERAL AGENT'S RIGHT TO INDEMNITY.
Except for action expressly required of the Loan Agent or the Collateral Agent
hereunder without instructions from any Person, the Loan Agent and the
Collateral Agent shall be fully justified in failing or refusing to take any
action hereunder on behalf of any Lender unless it shall first be indemnified to
its satisfaction by such Lender against any and all liability and expense which
may be incurred by it by reason of taking or continuing to take any such action.

          SECTION 7.7 INDEMNIFICATION OF LOAN AGENT AND COLLATERAL AGENT. The
Lenders hereby agree to indemnify the Loan Agent and the Collateral Agent and
all of their respective affiliates, directors, officers, employees, advisors and
representatives thereof (to the extent not reimbursed by the Borrowers), ratably
as most recently in effect prior to the date indemnification is sought, from and
against any and all costs, losses, liabilities, claims, damages or expenses
which may be incurred by or asserted or awarded against the Loan Agent or the
Collateral Agent in any way relating to or arising out of this Agreement and/or
the other Loan Documents or any action taken or omitted by the Loan Agent or the
Collateral Agent under this Agreement and/or the other Loan Documents; provided,
however, that no Lender shall be liable for any portion of such liabilities,
obligations, losses, damages, penalties, actions, judgments, suits, costs,
expenses or disbursements resulting from the Loan Agent's or the Collateral
Agent's gross negligence or willful misconduct. Without limiting the foregoing,
each Lender agrees to reimburse the Loan Agent and the Collateral Agent promptly
upon demand for its ratable share of any out-of-pocket expenses (including
counsel fees) incurred by the Loan Agent or the Collateral Agent in connection
with the administration, or enforcement of, or the preservation of any rights
under, this Agreement and/or the other Loan Documents, to the extent that the
Loan Agent or the Collateral Agent is not reimbursed for such expenses by the
Borrowers.

          SECTION 7.8 SUCCESSOR LOAN AGENT AND COLLATERAL AGENT. Each of the
Loan Agent and the Collateral Agent may with the consent (not to be unreasonably
withheld) of the Lenders and, if no Event of Default has occurred and is
continuing, the Borrowers (or, if an Event of Default has occurred and is
continuing and if legally permissible, upon notice to the Borrowers), resign at
any time by giving written notice thereof to the Lenders and may, at any time,
with or without cause, be removed by the Requisite Lenders acting through the
Loan Agent with, if no Event of Default has occurred and is continuing and if
the Collateral Agent is not in default of any Obligation under the Loan
Documents and if no representation or warranty of the Collateral Agent under the
Loan Documents has proven to be incorrect in any material respect, the consent
(not to be unreasonably withheld) of the Borrowers (or, if an Event of Default
has occurred and is continuing, upon notice to the Borrowers). Upon any such
resignation or



                                                                              66


removal, the Borrowers shall have the right to appoint a successor agent,
subject to consent of the Lenders. If no successor agent shall have accepted
such appointment within 30 days after (i) the retiring Loan Agent's or
Collateral Agent's, as applicable, giving of notice of resignation or (ii) the
Loan Agent giving notice, if legally permissible, of such removal, the Loan
Agent or the Collateral Agent, as applicable, may, with the consent (not to be
unreasonably withheld) of the Requisite Lenders and, if no Event of Default has
occurred and is continuing, the Borrowers, appoint a successor Loan Agent or
Collateral Agent, as applicable, who shall be willing to accept such
appointment. Upon the acceptance of any appointment as Loan Agent or Collateral
Agent hereunder by a successor Loan Agent or Collateral Agent, such successor
Loan Agent or Collateral Agent shall thereupon succeed to and become vested with
all the rights, powers, privileges and duties of the retiring or removed Loan
Agent or Collateral Agent, and the retiring or removed Loan Agent or Collateral
Agent shall be discharged from its duties and obligations as agent under this
Agreement. After any Loan Agent's or Collateral Agent's resignation or removal
hereunder as Loan Agent or Collateral Agent, as applicable, the provisions of
this Article 9 shall inure to its benefit as to any actions taken or omitted to
be taken by it while it was Loan Agent or Collateral Agent under this Agreement.

          SECTION 7.9 COLLATERAL AND GUARANTEE MATTERS. The Lenders irrevocably
authorize and direct the Collateral Agent to release any Lien on the Collateral
as provided for in the Collateral Documents.

                                  ARTICLE VIII

                                    GUARANTEE

          SECTION 8.1 GUARANTEE.

               (a) The Guarantor hereby unconditionally and irrevocably
guarantees to the Loan Agent, for the ratable benefit of the Lenders and their
respective successors, indorsees, transferees and assigns, the prompt and
complete payment and performance by the Borrowers when due (whether at the
stated maturity, by acceleration or otherwise) of the Obligations.

               (b) Anything herein or in any other Loan Document to the contrary
notwithstanding, the maximum liability of the Guarantor hereunder and under the
other Loan Documents shall in no event exceed the amount which can be guaranteed
by the Guarantor under applicable federal and state laws relating to the
insolvency of debtors.

               (c) The Guarantor agrees that the Obligations may at any time and
from time to time exceed the amount of the liability of the Guarantor hereunder
without impairing the guarantee contained in this Article VIII or affecting the
rights and remedies of the Loan Agent or any Lender hereunder.



                                                                              67


               (d) The guarantee contained in this Article VIII shall remain in
full force and effect until all the Obligations (including contingent
Obligations contained in any Loan Document that survive the termination thereof)
shall have been satisfied by payment in full and the Commitments shall be
terminated.

               (e) No payment made by either Borrower or the Guarantor, any
other guarantor or any other Person or received or collected by the Loan Agent
or any Lender from either Borrower, the Guarantor, any other guarantor or any
other Person by virtue of any action or proceeding or any set-off or
appropriation or application at any time or from time to time in reduction of or
in payment of the Obligations shall be deemed to modify, reduce, release or
otherwise affect the liability of the Guarantor hereunder which shall,
notwithstanding any such payment (other than any payment made by the Guarantor
in respect of the Obligations or any payment received or collected from such
Guarantor in respect of the Obligations), remain liable for the Obligations up
to the maximum liability of the Guarantor hereunder until the Obligations are
paid in full and the Commitments are terminated.

          SECTION 8.2 NO SUBROGATION. Notwithstanding any payment made by the
Guarantor hereunder or any set-off or application of funds of the Guarantor by
the Loan Agent or any Lender, the Guarantor shall not be entitled to be
subrogated to any of the rights of the Loan Agent or any Lender against either
Borrower or any other guarantor or any collateral security or guarantee or right
of offset held by the Loan Agent, the Collateral Agent or any Lender for the
payment of the Obligations, nor shall the Guarantor seek or be entitled to seek
any contribution or reimbursement from either Borrower or any other guarantor in
respect of payments made by such guarantor hereunder, until all amounts owing to
the Loan Agent and the Lenders by the Borrower on account of the Obligations
(other than contingent obligations contained in any Loan Document that survive
the termination thereof) are paid in full and the Commitments are terminated. If
any amount shall be paid to the Guarantor on account of such subrogation rights
at any time when all of the Obligations (other than contingent obligations
contained in any Loan Document that survive the termination thereof) shall not
have been paid in full, such amount shall be held by the Guarantor in trust for
the Loan Agent and the Lenders, segregated from other funds of the Guarantor,
and shall, forthwith upon receipt by the Guarantor, be turned over to the Loan
Agent in the exact form received by the Guarantor (duly indorsed by the
Guarantor to the Loan Agent, if required), to be applied against the
Obligations, whether matured or unmatured, in such order as the Loan Agent may
determine.

          SECTION 8.3 AMENDMENTS, ETC. WITH RESPECT TO THE OBLIGATIONS. The
Guarantor shall remain obligated hereunder notwithstanding that, without any
reservation of rights against the Guarantor and without notice to or further
assent by the Guarantor, any demand for payment of any of the Obligations made
by the Loan Agent or any Lender may be rescinded by the Loan Agent or such
Lender and any of the Obligations continued, and the Obligations, or the
liability of any other Person upon or for any part thereof, or any collateral
security or guarantee therefor or right of offset with respect thereto, may,
from time to time, in whole or in part, be renewed, extended, amended, modified,
accelerated, compromised, waived, surrendered or released by the Loan Agent



                                                                              68


or any Lender, and the Loan Documents and any other documents executed and
delivered in connection therewith may be amended, modified, supplemented or
terminated, in whole or in part, as the Loan Agent (or the Requisite Lenders or
all Lenders, as the case may be) may deem advisable from time to time, and any
collateral security, guarantee or right of offset at any time held by the Loan
Agent or any Lender for the payment of the Obligations may be sold, exchanged,
waived, surrendered or released. Neither the Loan Agent nor any Lender shall
have any obligation to protect, secure, perfect or insure any Lien at any time
held by it as security for the Obligations or for the guarantee contained in
this Section 8.3 or any property subject thereto.

          SECTION 8.4 GUARANTEE ABSOLUTE AND UNCONDITIONAL. The Guarantor waives
any and all notice of the creation, renewal, extension or accrual of any of the
Obligations and notice of or proof of reliance by the Loan Agent or any Lender
upon the guarantee contained in this Article VIII or acceptance of the guarantee
contained in this Article VIII; the Obligations, and any of them, shall
conclusively be deemed to have been created, contracted or incurred, or renewed,
extended, amended or waived, in reliance upon the guarantee contained in this
Article VIII; and all dealings between the Borrower and the Guarantor, on the
one hand, and the Loan Agent, the Collateral Agent and the Lenders, on the other
hand, likewise shall be conclusively presumed to have been had or consummated in
reliance upon the guarantee contained in this Article VIII. The Guarantor waives
diligence, presentment, protest, demand for payment and notice of default or
nonpayment to or upon the Borrower or the Guarantor with respect to the
Obligations. The Guarantor understands and agrees that the guarantee contained
in this Article VIII shall be construed as a continuing, absolute and
unconditional guarantee of payment without regard to (a) the validity or
enforceability of any other provisions of this Agreement or any other Loan
Document, any of the Obligations or any other collateral security therefor or
guarantee or right of offset with respect thereto at any time or from time to
time held by the Loan Agent, the Collateral Agent or any Lender, (b) any
defense, set-off or counterclaim (other than a defense of payment or
performance) which may at any time be available to or be asserted by the
Borrower or any other Person against the Loan Agent, the Collateral Agent or any
Lender, or (c) any other circumstance whatsoever (with or without notice to or
knowledge of a Borrower or the Guarantor) which constitutes, or might be
construed to constitute, an equitable or legal discharge of the Borrower for the
Obligations, or of the Guarantor under the guarantee contained in this Article
VIII, in bankruptcy or in any other instance. When making any demand hereunder
or otherwise pursuing its rights and remedies hereunder against the Guarantor,
the Loan Agent, the Collateral Agent or any Lender may, but shall be under no
obligation to, make a similar demand on or otherwise pursue such rights and
remedies as it may have against either Borrower, any other guarantor or any
other Person or against any collateral security or guarantee for the Obligations
or any right of offset with respect thereto, and any failure by the Loan Agent,
the Collateral Agent or any Lender to make any such demand, to pursue such other
rights or remedies or to collect any payments from the Borrower, any other
guarantor or any other Person or to realize upon any such collateral security or
guarantee or to exercise any such right of offset, or any release of the
Borrower, any other guarantor or any other Person or any such collateral
security, guarantee or right of offset, shall not relieve the Guarantor of any
obligation or liability hereunder, and shall not impair or affect the rights and
remedies, whether express,



                                                                              69


implied or available as a matter of law, of the Loan Agent, the Collateral Agent
or any Lender against the Guarantor. For the purposes hereof "demand" shall
include the commencement and continuance of any legal proceedings.

          SECTION 8.5 REINSTATEMENT. The guarantee contained in this Article
VIII shall continue to be effective, or be reinstated, as the case may be, if at
any time payment, or any part thereof, of any of the Obligations is rescinded or
must otherwise be restored or returned by the Loan Agent, the Collateral Agent
or any Lender upon the insolvency, bankruptcy, dissolution, liquidation or
reorganization of either Borrower or the Guarantor, or upon or as a result of
the appointment of a receiver, intervenor or conservator of, or trustee or
similar officer for, either Borrower or the Guarantor or any substantial part of
its property, or otherwise, all as though such payments had not been made.

          SECTION 8.6 PAYMENTS. The Guarantor hereby guarantees that payments
hereunder will be paid to the Loan Agent without set-off, counterclaim, claim of
recoupment or other defense in Dollars at the office specified in Section
2.9(a).

                                   ARTICLE IX

                                  MISCELLANEOUS

          SECTION 9.1 AMENDMENTS, WAIVERS, ETC.

               (a) No amendment, modification or waiver of any provision of this
Agreement or any other Loan Document nor consent to any departure by any Obligor
therefrom shall in any event be effective unless the same shall be in writing
and signed by the Requisite Lenders, and then any such waiver or consent shall
be effective only in the specific instance and for the specific purpose for
which given; provided, however, that no amendment, modification, waiver or
consent shall, unless in writing and signed by each Lender, do any of the
following:

                    (i) subject the Lenders to any additional obligations;

                    (ii) change the scheduled final maturity of the Loans, or
     change the amount or date for payment of any date fixed for the payment or
     reduction of principal;

                    (iii) change the principal amount of any Loan (other than by
     the payment or prepayment thereof);

                    (iv) change the rate of interest on any Loan or any fee,
     indemnity or other amount payable to any Lender;

                    (v) change any date fixed for payment of such interest,
     indemnity or other amount or fees;



                                                                              70


                    (vi) amend the definition of "Requisite Lenders" or this
     Section 9.1(a);

                    (vii) modify the application of payments to the Loan under
     Section 2.9; or

                    (viii) release all or substantially all of the Collateral or
     release the Guarantor from the guarantee contained in Article VIII;

and provided, further, that no amendment, modification, waiver or consent shall,
unless in writing and signed by the Loan Agent in addition to the Persons
required above to take such action, affect the rights or duties of the Loan
Agent under this Agreement or the other Loan Documents.

               (b) The Loan Agent may, but shall have no obligation to, with the
written concurrence of any Lender, execute amendments, modifications, waivers or
consents on behalf of that Lender. Any waiver or consent shall be effective only
in the specific instance and for the specific purpose for which it was given. No
notice to or demand on the Borrowers in any case shall entitle the Borrowers to
any other or further notice or demand in similar or other circumstances.

               (c) In connection with any proposed amendment, modification,
waiver or termination (a "Proposed Change") requiring the consent of all
affected Lenders, if the consent of the Loan Agent and of the Requisite Lenders
is obtained, but the consent of other Lenders whose consent is required is not
obtained (any such Lender whose consent is not obtained as described in this
Section 9.1 being referred to as a "Non-Consenting Lender"), then (i) at the
Borrowers' request, the Loan Agent shall have the right in the Loan Agent's sole
discretion (but shall have no obligation) to purchase from such Non-Consenting
Lender, and such Non-Consenting Lender agrees that it shall, upon the Loan
Agent's request, sell and assign to the Lender that is acting as the Loan Agent,
all of the portion of the Loan of such Non-Consenting Lender for an amount equal
to the principal balance of such portion of the Loan held by the Non-Consenting
Lender and all accrued interest and fees with respect thereto through the date
of sale, such purchase and sale to be consummated pursuant to an executed
Assignment and Assumption, and (ii) the Borrowers may effect a substitution of
the Non-Consenting Lender pursuant to Section 2.12.

          SECTION 9.2 SUCCESSORS AND ASSIGNS; PARTICIPATIONS AND ASSIGNMENTS.

               (a) The provisions of this Agreement shall be binding upon and
inure to the benefit of the parties hereto and their respective successors and
assigns permitted hereby, except that (i) the Borrowers may not assign or
otherwise transfer any of their rights or obligations hereunder without the
prior written consent of each Lender (and any attempted assignment or transfer
by the Borrowers without such consent shall be null and void) and (ii) no Lender
may assign or otherwise transfer its rights or obligations hereunder except in
accordance with this Section.



                                                                              71


               (b) (i) Subject to the conditions set forth in paragraph (b)(ii)
below, any Lender may assign to one or more entities (each, an "Assignee"),
including by means of a capital markets, private placement or securitization
transaction, all or a portion of its rights and obligations under this Agreement
(including all or a portion of its Commitments and the Loans at the time owing
to it) and subject to the following additional conditions:

                         (A) such Assignee shall not be an airline, a commercial
          aircraft operator, an air freight forwarder, an entity engaged in the
          business of parcel transport by air, other similar Person, or a
          holding company Affiliate of any of the foregoing; and

                         (B) prior written notice of any such assignment shall
          be provided to the Borrowers unless an Event of Default has occurred
          and is continuing;

                         (C) in the event of an assignment involving a
          widespread syndication or offering, if the Guarantor or any Borrower
          indicates that the proposed transaction would interfere with its own
          debt financing efforts, such Lender agrees to cooperate in good faith
          with the Guarantor or such Borrower in order not to hinder the
          Guarantor's or such Borrower's attempt to finalize its financing; and

                         (D) an assignee or participant that acquires its
          interest in the Obligations pursuant to or in connection with a
          capital markets, private placement, or securitization transaction
          pursuant to which ten or more persons acquire interests in the
          Obligations shall not be entitled to the benefits of Section 2.13.

                    (ii) Assignments shall be subject to the additional
     condition that the parties to each assignment shall execute and deliver to
     the Loan Agent an Assignment and Assumption.

                    (iii) Subject to acceptance and recording thereof pursuant
     to paragraph (b)(iv) below, from and after the effective date specified in
     each Assignment and Assumption the Assignee thereunder shall be a party
     hereto and, to the extent of the interest assigned by such Assignment and
     Assumption, have the rights and obligations of a Lender under this
     Agreement, and the assigning Lender thereunder shall, to the extent of the
     interest assigned by such Assignment and Assumption, be released from its
     obligations under this Agreement (and, in the case of an Assignment and
     Assumption covering all of the assigning Lender's rights and obligations
     under this Agreement, such Lender shall cease to be a party hereto but
     shall continue to be entitled to the benefits of Sections 2.10, 2.11, 2.13,
     9.3 and 9.4). Any assignment or transfer by a Lender of rights or
     obligations under this Agreement that does not comply with this Section
     10.2 shall be treated for purposes of this Agreement as a sale by



                                                                              72


     such Lender of a participation in such rights and obligations in accordance
     with paragraph (c) of this Section.

                    (iv) Upon its receipt of a duly completed Assignment and
     Assumption executed by an assigning Lender and an Assignee, the Loan Agent
     shall accept such Assignment and Assumption and record the information
     contained therein in the Register. No assignment shall be effective for
     purposes of this Agreement unless it has been recorded in the Register as
     provided in this paragraph.

                    (v) The Initial Lender agrees to notify the Borrowers
     promptly following the date on which it or its Affiliate has fully or
     partially assigned or sold all or a portion of its rights and obligations
     under this Agreement.

               (c) (i) Any Lender may, without the consent of the Borrowers or
the Loan Agent, sell participations to one or more banks or other entities (a
"Participant") in all or a portion of such Lender's rights and obligations under
this Agreement (including all or a portion of its Commitments and the Loans
owing to it); provided that (A) such Participant shall not be an airline, a
commercial aircraft operator, an air freight forwarder, an entity engaged in the
business of parcel transport by air, other similar Person, or a holding company
Affiliate of any of the foregoing, (B) such Lender's obligations under this
Agreement shall remain unchanged, (C) such Lender shall remain solely
responsible to the other parties hereto for the performance of such obligations
and (D) the Obligors, the Loan Agent, and the Lenders shall continue to deal
solely and directly with such Lender in connection with such Lender's rights and
obligations under this Agreement. Any agreement pursuant to which a Lender sells
such a participation shall provide that such Lender shall retain the sole right
to enforce this Agreement. Subject to paragraph (c)(ii) of this Section, the
Borrowers agree that, if its interest is entered in the Register, each
Participant shall be entitled to the benefits of Sections 2.10, 2.11, 2.13, 9.3
and 9.4 to the same extent as if it were a Lender and had acquired its interest
by assignment pursuant to paragraph (b) of this Section. To the extent permitted
by law, each Participant also shall be entitled to the benefits of Section 9.5
as though it were a Lender, provided such Participant shall be subject to
Section 9.7 as though it were a Lender.

                    (ii) Borrowers shall not be required to provide, and a
     Participant shall not be entitled to receive any greater payment under
     Section 2.10, 2.11 or 2.13 than the Borrowers would have been required to
     pay and the applicable Lender would have been entitled to receive with
     respect to the participation sold to such Participant, unless the sale of
     the participation to such Participant is made with the Borrowers' prior
     written consent. Any Participant shall not be entitled to the benefits of
     Section 2.13 unless such Participant complies with Section 2.13(f).

               (d) Any Lender may at any time pledge or assign a security
interest in all or any portion of its rights under this Agreement to secure
obligations of



                                                                              73


such Lender, including any pledge or assignment to secure obligations to a
Federal Reserve Bank, and this Section shall not apply to any such pledge or
assignment of a security interest; provided that no such pledge or assignment of
a security interest shall release a Lender from any of its obligations hereunder
or substitute any such pledgee or Assignee for such Lender as a party hereto.

               (e) The Obligors agree to cooperate with the efforts of the
Initial Lender to engage in a transfer or sell-down transaction as envisioned in
this Section 9.2, including by means of restructuring the Loan Documents into
tranches (not all of which need to be secured by the Collateral), restructuring
the Loan Documents into a capital markets style indenture, cooperating in
reasonable due diligence meetings and investor phone calls, providing accountant
comfort letters and legal opinion reliance letters, and assisting with the
reasonable requests of rating agencies and investors, all at the cost of the
Initial Lender for the reasonable out-of-pocket expenses of Borrower in
cooperating as provided in this subparagraph. Without limiting the generality of
the foregoing, as part of the cooperation of the Obligors, if requested by the
Initial Lender in connection with a transfer or sell down transaction as
envisioned in this Section 9.2, the Loan Documents shall be "marked-to-market"
and amended accordingly, solely to reflect any prepayment premiums or make-whole
amounts or other prepayment terms and conditions which are at the time customary
for comparable financings in the relevant markets, as determined in the opinion
of two investment banks, one selected by the Borrowers and the other by the Loan
Agent, and if such banks fail to agree on such prepayment premiums or make-whole
amounts or other prepayment terms and conditions, then a third investment bank
mutually selected by the Borrowers and the Loan Agent shall make such
determination.

          SECTION 9.3 COSTS AND EXPENSES. Whether or not the first Funding Date
occurs, the Obligors agree to pay within ten Business Days (or as provided in
Section 3.1(d)) following receipt of a reasonably detailed invoice therefor (i)
all reasonable out-of-pocket costs and expenses (including reasonable legal fees
and expenses of one primary outside counsel and one special FAA counsel)
incurred by the Initial Lender, the Loan Agent and the Collateral Agent in
connection with the negotiation, preparation, execution and delivery of the Loan
Documents, and all documents relating thereto, (ii) all reasonable out-of-pocket
costs and expenses (including reasonable legal fees and expenses of one primary
outside counsel and one special FAA counsel) incurred by the Loan Agent in
connection with any consents, amendments, waivers or other modifications hereto
or thereto, (iii) all reasonable out-of-pocket costs and expenses incurred by
the Loan Agent in connection with the syndication of the Loans (if any), and
(iv) all reasonable out-of-pocket costs and expenses (including reasonable legal
fees and expenses) incurred by the Loan Agent and the Lenders in enforcing any
Obligations of, or in collecting any payments due from, the Borrowers hereunder
or under the other Loan Documents.

          SECTION 9.4 INDEMNITIES. Whether or not the transactions contemplated
hereby shall be consummated, the Obligors agree to defend, indemnify, pay and
hold harmless the Loan Agent, the Lenders, and their respective Affiliates,
officers, directors, employees, agents and controlling Persons (collectively
called the "Indemnitees") from



                                                                              74


and against any and all liabilities, obligations, losses, damages, penalties,
actions, judgments, suits, claims, costs, expenses and disbursements of any kind
or nature whatsoever (including without limitation the reasonable fees and
disbursements of outside counsel for such Indemnitees, but excluding Taxes) that
may be imposed on, incurred by, or asserted against any such Indemnitee, in any
manner arising out of this Agreement or the other Loan Documents or the
transactions contemplated hereby or thereby (including, without limitation, the
use or intended use of the proceeds of the Loan) or any breach or default by the
Borrowers of any provision of the Loan Documents (collectively called the
"Indemnified Liabilities"); provided that the Obligors shall not have any
obligation to any Indemnitee hereunder with respect to any Indemnified
Liabilities to the extent such Indemnified Liabilities (i) arise from the gross
negligence or willful misconduct of an Indemnitee, (ii) are specifically
addressed elsewhere in this Agreement (including, without limitation, Section
2.10, (iii) arise from breaches by an Indemnitee of any Loan Document to which
it is a party, or (iv) constitute ordinary and usual operating or overhead
expenses of an Indemnitee (excluding, without limitation, costs and expenses of
any outside counsel, consultant or agent). To the extent that the undertaking to
defend, indemnify, pay and hold harmless set forth in the preceding sentence may
be unenforceable because it is violative of any law or public policy, the
Obligors shall contribute the maximum portion that it is permitted to pay and
satisfy under applicable law to the payment and satisfaction of all Indemnified
Liabilities incurred by the Indemnitees or any of them.

          SECTION 9.5 RIGHT OF SET-OFF. In addition to any rights now or
hereafter granted under applicable law and not by way of limitation of any such
rights, upon the occurrence and during the continuance of any Event of Default,
to the fullest extent permitted by law, each Lender is hereby authorized by the
Obligors at any time or from time to time, without notice to the Obligors or to
any other Person, any such notice being hereby expressly waived, to set off and
to appropriate and to apply any and all deposits (general or special, including,
but not limited to, Indebtedness evidenced by certificates of deposit, whether
matured or unmatured) and any other Indebtedness at any time held or owing by
that Lender to or for the credit or the account of any Obligor against and on
account of the Obligations then due.

          SECTION 9.6 JOINT AND SEVERAL LIABILITY; MAXIMUM LIABILITY; WAIVER OF
SUBROGATION.

               (a) Each Borrower shall be liable for all amounts due to the
Lenders under this Agreement, regardless of which Borrowers actually receives
the Loans or other extensions of credit hereunder, or the amount of such Loans
received or the manner in which any Lender accounts for such Loans or other
extensions of credit on its books and records. Each Borrower's liabilities with
respect to Loans and extensions of credit made to it, and each Borrower's
liabilities arising as a result of the joint and several liability of the
Borrowers hereunder and under the other Loan Documents with respect to Loans or
other extensions of credit made to any other Borrowers hereunder, shall be
separate and distinct obligations, but all such liabilities shall be primary
obligations of each Borrower. The joint and several liability of each Borrower
shall in all respects be continuing, absolute, unconditional and irrevocable, in
all events and



                                                                              75


circumstances, and shall continue in full force and effect until all Obligations
have been paid in full and all Commitments shall have terminated, and will be
paid strictly in accordance with the terms of this Agreement and each other Loan
Document under which they arise, regardless of any law, regulation or order now
or hereafter in effect in any jurisdiction affecting any of such terms or the
rights of Lender or any holder of any Loan or Note with respect thereto.

               (b) Notwithstanding any payment made by either Borrower or the
Guarantor hereunder or any set-off or application of funds of either Borrower or
the Guarantor by the Loan Agent or any Lender, neither Borrower shall be
entitled to be subrogated to any of the rights of the Loan Agent, the Collateral
Agent or any Lender against either Borrower or the Guarantor or any collateral
security or guarantee or right of offset held by the Loan Agent, the Collateral
Agent or any Lender for the payment of the Obligations, nor shall either
Borrower seek or be entitled to seek any contribution or reimbursement from the
other Borrower or the Guarantor in respect of payments made by the Guarantor
hereunder, until all amounts owing to the Loan Agent, the Collateral Agent and
the Lenders by the Borrowers on account of the Obligations are paid in full and
the Commitments are terminated. If any amount shall be paid to either Borrower
on account of such subrogation rights at any time when all of the Obligations
shall not have been paid in full, such amount shall be held by such Borrower in
trust for the Loan Agent, the Collateral Agent and the Lenders, segregated from
other funds of such Borrower, and shall, forthwith upon receipt by such
Borrower, be turned over to the Loan Agent in the exact form received by such
Borrower (duly indorsed by such Borrower to the Loan Agent, if required), to be
applied against the Obligations, whether matured or unmatured, in such order as
the Loan Agent may determine.

               (c) Each Borrower shall remain obligated hereunder
notwithstanding that, without any reservation of rights against the other
Borrower or the Guarantor and without notice to or further assent by the other
Borrower or the Guarantor, any demand for payment of any of the Obligations made
by the Loan Agent, the Collateral Agent or any Lender may be rescinded by the
Loan Agent, the Collateral Agent or such Lender and any of the Obligations
continued, and the Obligations, or the liability of any other Person upon or for
any part thereof, or any collateral security or guarantee therefor or right of
offset with respect thereto, may, from time to time, in whole or in part, be
renewed, extended, amended, modified, accelerated, compromised, waived,
surrendered or released by the Loan Agent, the Collateral Agent or any Lender,
and this Agreement and the other Loan Documents and any other documents executed
and delivered in connection therewith may be amended, modified, supplemented or
terminated, in whole or in part, as the Loan Agent (or the Requisite Lenders or
all Lenders, as the case may be) may deem advisable from time to time, and any
collateral security, guarantee or right of offset at any time held by the Loan
Agent, the Collateral Agent or any Lender for the payment of the Obligations may
be sold, exchanged, waived, surrendered or released. Neither the Loan Agent, the
Collateral Agent nor any Lender shall have any obligation to protect, secure,
perfect or insure any Lien at any time held by it as security for the
Obligations or for the guarantee contained in Article VIII or any property
subject thereto.



                                                                              76


               (d) Each Borrower waives any and all notice of the creation,
renewal, extension or accrual of any of the Obligations and notice of or proof
of reliance by the Loan Agent, the Collateral Agent or any Lender upon the joint
and several liability of the Borrowers and the guarantee contained in Article
VIII or acceptance thereof; the Obligations, and any of them, shall conclusively
be deemed to have been created, contracted or incurred, or renewed, extended,
amended or waived, in reliance upon the joint and several liability of the
Borrowers and the guarantee contained in Article VIII; and all dealings between
the Borrowers and the Guarantor, on the one hand, and the Loan Agent, the
Collateral Agent and the Lenders, on the other hand, likewise shall be
conclusively presumed to have been had or consummated in reliance thereupon.
Each Borrower waives diligence, presentment, protest, demand for payment and
notice of default or nonpayment to or upon the other Borrower or the Guarantor
with respect to the Obligations. Each Borrower understands and agrees that its
joint and several liability hereunder for and with respect to the Obligations of
the other Borrower is continuing, absolute and unconditional without regard to
any circumstance whatsoever which constitutes, or might be construed to
constitute, an equitable or legal discharge of such Borrower for and with
respect to the Obligations of the other Borrower (or of the Guarantor), in
bankruptcy or in any other instance. When making any demand hereunder or
otherwise pursuing its rights and remedies hereunder against either Borrower,
the Loan Agent, the Collateral Agent or any Lender may, but shall be under no
obligation to, make a similar demand on or otherwise pursue such rights and
remedies as it may have against the other Borrower, the Guarantor or any other
Person or against any collateral security or guarantee for the Obligations or
any right of offset with respect thereto, and any failure by the Loan Agent, the
Collateral Agent or any Lender to make any such demand, to pursue such other
rights or remedies or to collect any payments from the other Borrower, the
Guarantor or any other Person or to realize upon any such collateral security or
guarantee or to exercise any such right of offset, or any release of the other
Borrower, the Guarantor or any other Person or any such collateral security,
guarantee or right of offset, shall not relieve a Borrower of any obligation or
liability hereunder, and shall not impair or affect the rights and remedies,
whether express, implied or available as a matter of law, of the Loan Agent, the
Collateral Agent or any Lender against either Borrower. For the purposes hereof
"demand" shall include the commencement and continuance of any legal
proceedings.

               (e) The joint liability of the Borrowers shall continue to be
effective, or be reinstated, as the case may be, if at any time payment, or any
part thereof, of any of the Obligations is rescinded or must otherwise be
restored or returned by the Loan Agent, the Collateral Agent or any Lender upon
the insolvency, bankruptcy, dissolution, liquidation or reorganization of a
Borrower or the Guarantor, or upon or as a result of the appointment of a
receiver, intervenor or conservator of, or trustee or similar officer for, a
Borrower or the Guarantor or any substantial part of its property, or otherwise,
all as though such payments had not been made.

          SECTION 9.7 SHARING OF PAYMENTS, ETC. The Lenders hereby agree among
themselves that if any of them shall, whether by voluntary payment, by
realization upon security, through the exercise of any right of set-off or
banker's lien, by counterclaim or cross action or by the enforcement of any
right under the Loan



                                                                              77


Documents or otherwise, or as adequate protection of a deposit treated as cash
collateral under the Bankruptcy Code, receive payment or reduction of a
proportion of the aggregate amount of principal, interest, fees and other
amounts then due and owing to that Lender hereunder or under the other Loan
Documents (collectively, except as provided in the immediately following
exception clause, the "Aggregate Amounts Due" to each Lender) which is greater
than the proportion received by any other Lender in respect of the Aggregate
Amounts Due to such other Lender, except by reason of payments that are
individual to a particular Lender under Sections 2.10(c), 2.10(e), 2.11, 2.13,
9.3 and 9.4, then the Lender receiving such proportionately greater payment
shall (i) notify the Loan Agent and each other Lender of the receipt of such
payment and (ii) apply a portion of such payment to purchase participations
(which it shall be deemed to have purchased from each seller of a participation
simultaneously upon the receipt by such seller of its portion of such payment)
in the Aggregate Amounts Due to the other Lenders so that all such recoveries of
Aggregate Amounts Due shall be shared by all Lenders in proportion to the
Aggregate Amounts Due to them, provided that if all or part of such
proportionately greater payment received by such purchasing Lender is thereafter
recovered from such Lender upon the bankruptcy or reorganization of the
Borrowers or otherwise, those purchases shall be rescinded and the purchase
prices paid for such participations shall be returned to such purchasing Lender
ratably to the extent of such recovery, but without interest. The Obligors
expressly consent to the foregoing arrangement and agrees that any holder of a
participation so purchased may exercise any and all rights of banker's lien,
set-off or counterclaim with respect to any and all monies owing by the Obligors
to that holder with respect thereto as fully as if that holder were owed the
amount of the participation held by that holder.

          SECTION 9.8 NOTICES, ETC. Unless otherwise specifically provided
herein, any notice, request or other communication herein required or permitted
to be given shall be in writing and may be personally served or sent by
telefacsimile or United States mail or courier service and shall be deemed to
have been given when delivered in person or by courier service, or upon receipt

          SECTION 9.9 NO WAIVER; REMEDIES. No failure on the part of any Lender
or the Loan Agent or the Collateral Agent to exercise, and no delay in
exercising, any right hereunder shall operate as a waiver thereof; nor shall any
single or partial exercise of any such right preclude any other or further
exercise thereof or the exercise of any other right. The remedies herein
provided are cumulative and not exclusive of any remedies provided by law.



                                                                              78

1. The Assignor hereby irrevocably sells and assigns to the Assignee without
recourse to the Assignor, and the Assignee hereby irrevocably purchases and
assumes from the Assignor without recourse to the Assignor, as of the Effective
Date (as defined below), the interest described in Schedule 1 hereto (the

Loan Agreement with respect to those credit facilities contained in the Loan
Agreement as are set forth on Schedule 1 hereto (individually, an "Assigned

each Assigned Facility as set forth on Schedule 1 hereto.

2. The Assignor (a) makes no representation or warranty and assumes no
responsibility with respect to any statements, warranties or representations

created any adverse claim upon the interest being assigned by it hereunder and
that such interest is free and clear of any such adverse claim and (b) makes no
representation or warranty and assumes no responsibility with respect to the
financial condition of the Guarantor, the Borrower, any of its Affiliates or any

powers as are incidental thereto; and (e) agrees that it will be bound by the
provisions of the Loan Agreement and will perform in accordance with its terms
all the obligations which by the terms of the Loan Agreement are required to be
performed by it as a Lender including its obligations pursuant to Section

4. The effective date of this Assignment and Assumption shall be the Effective
Date of Assignment described in Schedule 1 hereto (the "Effective Date").
Following the execution of this Assignment and Assumption, it will be delivered

to the Credit Agreement, effective as of the Effective Date (which shall not,
unless otherwise agreed to by the Loan Agent, be earlier than five Business Days

5. Upon such acceptance and recording, from and after the Effective Date, the
Loan Agent shall make all payments in respect of the Assigned Interest
(including payments of principal, interest, fees and other amounts) to the
Assignor for amounts which have accrued to the Effective Date and to the
Assignee for amounts which have accrued subsequent to the Effective Date.

6. From and after the Effective Date, (a) the Assignee shall be a party to the
