Notwithstanding anything herein to the contrary, the Borrower shall repay the
entire unpaid principal amount of the Loan together with accrued and unpaid
interest thereon and all other amounts owing hereunder in respect thereof on the
Loan Maturity Date.

                  (b)      On or before April 30 of each year the Borrower shall
repay the Loan in an amount equal to the Labor Cost Payment Amount, if any, for
the immediately preceding Fiscal Year, together with accrued interest with
respect thereto to the date of payment. Promptly upon the filing of the
Borrower's Form 10-K for each Fiscal Year (but in no event later than 15 days
thereafter), the Borrower, after consultation with the Board, shall provide to
the Agent, the Lenders, the Counter-Guarantors, the Loan Administrator and the
Board a certificate signed by the Chief Financial Officer of the Borrower
certifying the amount of the Labor Cost Payment Amount and demonstrating in
reasonable detail the calculations to determine the Labor Cost Payment Amount
for such Fiscal Year. Any such payment of the Loan shall be applied to the then
remaining installments of the outstanding principal balance of the Loan in the
inverse order of maturity thereof. If any such payment is made on a date other
than an Interest Payment Date, the Borrower shall also pay any amounts owing
pursuant to Section 2.10(e). Any such payment shall be paid to the Agent for
application as provided in Section 2.9.

                  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
Loan outstanding from time to time, including the amounts of principal and
interest payable and paid to such Lender from time to time under this Agreement.

                  (b)      The Agent shall establish and maintain a register for
recording with respect to the Loan (i) the date and amount of each payment on
the Loan made by or on behalf of, or collected from, the Borrower, (ii) 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 Loan and to each of the fees identified in clauses (d) through
(h) of Section 2.8 hereof, and (iii) the date and amount of each payment made by
the Board under the Board Guarantee.

                  (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 Agent to maintain such accounts or any error therein shall not in any
manner affect the obligations of the Borrower to repay the Loan in accordance
with its terms.

                  (d)      The Borrower shall execute and deliver to the Agent
on the Closing Date a single promissory note substantially in the form of
Exhibit B in the principal amount of the Loan, dated the Closing Date and
otherwise appropriately completed (such note, including any replacement note
therefor issued in accordance with

                                       22
<PAGE>
the provisions of this Section 2.4(d), the "Note"). The Note shall be made
payable to the Agent at the office of the Agent. If the Note is mutilated, lost,
stolen or destroyed, the Borrower shall issue a new Note in the same principal
amount and having the same interest rate, date and maturity as the Note so
mutilated, lost, stolen or destroyed endorsed to indicate all payments thereon.
In the case of any lost, stolen or destroyed Note, there shall first be
furnished to the Borrower and the Board an instrument of indemnity from the
Agent and evidence of such loss, theft or destruction reasonably satisfactory to
each of them, together with an officer's certificate of the Borrower certifying
and warranting as to the due authorization, execution and delivery of the new
Note.

                  (e)      This Agreement and the Note are registered
instruments. A manually signed copy of this Agreement and the original of the
Note shall be evidence of (i) the rights of each Lender under this Agreement and
the Note and (ii) the rights of the Agent under this Agreement. Neither this
Agreement nor the Note is a bearer instrument. The Agent will establish and
maintain a record of ownership (the "Register") in which the Agent agrees to
register by book entry the Agent's and each Lender's interest in the Loan, the
Note 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 10.2, the Agent shall maintain a copy of each
Assignment and Acceptance delivered to and accepted by it and shall record the
names and addresses of the Lenders and principal amount of the Loan owing to
each Lender from time to time. The entries in the Register shall be conclusive
and binding for all purposes, absent manifest error, and the Borrower, the
Board, the Agent and the Lenders may treat each Person whose name is recorded in
the Register as a Lender for all purposes of this Agreement. The Register shall
be available for inspection by the Borrower, the Agent, the Board or any Lender
at any reasonable time and from time to time upon reasonable prior notice.

                  (f)      The Borrower shall apply the proceeds from the Loan
as necessary to cure all Disclosed Defaults (and promptly following the Closing
Date, shall confirm in writing such use to the Board), and thereafter may use
the balance of such proceeds for such general corporate purposes as are
permissible under the Act and Regulations but not for the prepayment or
refinancing of any Indebtedness of the Borrower for borrowed money nor for the
acquisition of the stock, or of all or any substantial part of the assets, of
any Person. No portion of the proceeds from the Borrowing shall be used by the
Borrower or any of its Subsidiaries in any manner that might 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.

                                       23
<PAGE>
                  (a)      The Borrower may, upon at least fifteen days' prior
revocable notice to the Board, the Counter-Guarantors, the Loan Administrator
and the Agent stating the proposed date and aggregate principal amount of the
prepayment, elect to prepay the outstanding principal amount of the Loan, in
whole or in part (but not less than a minimum amount of $2,500,000), 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 the
Loan is made by the Borrower other than on an Interest Payment Date or if the
Borrower revokes such notice at any time within such fifteen days, the Borrower
shall also pay any amounts owing pursuant to Section 2.10(e). The Borrower shall
establish to the satisfaction of the Board and the Agent three Business Days in
advance of any prepayment of the Loan its ability to pay the amount to be
prepaid.

                  (b)      Upon the giving of any notice of prepayment under
clause (a) of this Section 2.5, the principal amount of the Loan specified to be
prepaid together with accrued and unpaid interest thereon 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 Borrower 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 Loan under this Section
2.5 shall be applied to the then remaining installments of the outstanding
principal amount of the Loan in the inverse order of maturity thereof. Any such
prepayment shall be paid to the Agent for application as provided in Section
2.9. The Borrower shall have no right to optionally prepay the principal amount
of the Loan other than as provided in this Section 2.5, Section 2.10(b) or
Section 2.10(d).

                  SECTION 2.6.      MANDATORY PREPAYMENTS.

Loan Administrator and the Board not less than five Business Days' prior written
notice of any anticipated Future Issuance and upon receipt by the Borrower of
the proceeds of such Future Issuance, the Borrower shall prepay the Loan in the
manner provided below in an amount equal to the amount of such proceeds net of
any reasonable and customary brokers' and advisors' fees, any underwriting
discounts and commissions and other costs incurred in connection with such
transaction (provided that evidence of such fees, discounts, commissions and
costs is provided to the Board and the Agent); provided, that, the Borrower
shall not be obligated to so prepay the Loan if and to the extent that (i) the
Borrower is prohibited from so prepaying the Loan under the terms of the Senior
Notes and the Borrower applies such proceeds to repay the Senior Notes, (ii) the
Borrower applies such proceeds from an issue or incurrence of Indebtedness to
finance Aircraft Related Equipment in a transaction of the type excepted from
the definition of Asset Sales in this Agreement, (iii) such Future Issuance
involves only the exercise of options

                                       24
<PAGE>
or similar rights issued as compensation by existing or former officers,
directors or employees of the Borrower, Holdings or any of their Subsidiaries or
(iv) the Borrower applies such proceeds to purchase Aircraft Related Equipment.
Any partial prepayments of the Loan made by the Borrower in accordance with this
Section 2.6(a) shall be applied to the then remaining installments of the
outstanding principal balance of the Loan in the inverse order of maturity
thereof. If any such prepayment is made by the Borrower other than on an
Interest Payment Date, the Borrower shall also pay any amounts owing pursuant to
Section 2.10(e). Any such prepayment of the Loan shall be made on the date of
the Borrower's receipt of the proceeds of the applicable Future Issuance, and
shall be paid to the Agent for application as provided in Section 2.9.

                  (b)      Asset Sales. No later than three Business Days
following the date on which any Excess Proceeds are not applied as set forth in
Section 6.10, the Borrower shall prepay the Loan in an aggregate amount equal to
such non-applied Excess Proceeds. Any partial prepayments of the Loan made by
the Borrower in accordance with this Section 2.6(b) shall be applied to the then
remaining installments of the outstanding principal balance of the Loan in the
inverse order of maturity thereof. If any such prepayment is made by the
Borrower other than on an Interest Payment Date, the Borrower shall also pay any
amounts owing pursuant to Section 2.10(e). Any such prepayment of the Loan shall
be paid to the Agent for application as provided in Section 2.9.

                  (c)      Insurance/Condemnation Proceeds. No later than three
Business Days following the date of receipt by the Borrower or any of its
Subsidiaries of any Net Insurance Proceeds, or if applicable, the end of the
six-month period described in clause (ii) below, the Borrower shall prepay the
Loan in an amount equal to the amount by which the aggregate amount of such Net
Insurance Proceeds in any Fiscal Year exceeds $2,000,000; provided, (i) if and
to the extent that the application of such Net Insurance Proceeds to the Loan
are not permitted under the terms of the Senior Notes and are not used as in
clause (ii) below, the Borrower shall apply such Net Insurance Proceeds to
prepay the Senior Notes, and (ii) the Borrower shall not be obligated to so
prepay the Loan if and to the extent that the Borrower certifies to the Board
that it intends to repair, restore or replace the assets from which such Net
Insurance Proceeds derived, and does so (or enters into a definitive agreement
committing to do so) within 6 months of receipt thereof. Any partial prepayments
of the Loan made by the Borrower in accordance with this Section 2.6(c) shall be
applied to the then remaining installments of the outstanding principal balance
of the Loan in the inverse order of maturity thereof. If any such prepayment is
made by the Borrower other than on an Interest Payment Date, the Borrower shall
also pay any amounts owing pursuant to Section 2.10(e). Any such prepayment of
the Loan shall be paid to the Agent for application as provided in Section 2.9.

                  (d)      Change in Control. Upon the occurrence of a Change in
Control with respect to either Holdings or the Borrower, the Borrower shall
promptly give the Agent, the Lenders, the Loan Administrator and the Board
written notice thereof, and the

                                       25
<PAGE>
Board shall have the right, by written notice to the Borrower (with a copy to
the Agent and each Lender) delivered not more than 30 days following delivery of
the notice of the Change in Control, to require the Borrower to prepay the Loan
in full, together with accrued interest thereon to the date of such prepayment,
on the date specified in such notice (which date shall be a Business Day not
less than ten nor more than twenty Business Days' after the date of such
notice), and upon the specified payment date, the Borrower shall so prepay the
then outstanding principal amount of the Loan together with such accrued
interest thereon. If any such prepayment is made on any date other than an
Interest Payment Date, the Borrower shall also pay any amounts owing pursuant to
Section 2.10(e). Any such prepayment shall be paid to the Agent for application
as provided in Section 2.9.

                  SECTION 2.7.      INTEREST.

                  (a)      Rate of Interest. Except as otherwise provided in
Section 2.7(c) and Section 2.10, the Loan shall bear interest on the unpaid

Applicable Interest Rate.

                  (b)      Interest Payments. Interest accrued on the Loan and
the Note shall be payable in arrears on the last day of each Interest Period (an
"Interest Payment Date"), upon the payment or prepayment thereof in whole or in
part, and, if not previously paid in full, at maturity (whether by acceleration
or otherwise). Interest on the 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 the Loan or any fee or other amount payable by the Borrower
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.

                  (a)      SSB Structuring Fee. The Borrower agrees to pay to

<PAGE>
                  (c)      Facility Fee. The Borrower agrees to pay to the Agent
for the account of the Initial Lender on the Closing Date a facility fee in an
amount equal to $[...***...].

                  (d)      Agency Fee. The Borrower agrees to pay to the Agent
on the Closing Date and annually thereafter an agency fee in an amount equal to
$[...***...] per annum for so long as the Loan shall remain outstanding.

                  (e)      Loan Administrator Fee.

                  (i) Basic Fee. Subject to subsection (ii) below, the Borrower
agrees to pay to the Loan Administrator on the Closing Date and annually
thereafter on each anniversary of the Closing Date a Loan Administrator fee in
an amount equal to $[...***...] per annum for so long as the Loan shall remain
outstanding.

                  (ii) Annual Adjustment. On each anniversary of the Closing
Date, the Loan Administrator shall provide the Borrower with a statement
indicating (A) the total number of hours actually worked during the preceding
year, (B) the hourly rates charged for such services in accordance with the rate
schedule attached as Schedule 2.8 (increased annually on each anniversary of the
Closing Date by not more than [...***...]%), and (C) the total value of the
services rendered, determined by multiplying (A) times (B) (the "Actual Costs").
If the sum of (x) the Actual Costs for the preceding year and (y) the fee
charged by the sub-servicer referred to in Section 8.1(b)(iv) for the preceding
year (such sum referred to as "Total Costs") is less than $[...***...], the fee
to be paid to the Loan Administrator on the next anniversary of the Closing Date
in accordance with clause (i) of this subsection (e) shall be reduced by the
difference. If the Total Costs for the preceding year is greater than
$[...***...], the fee to be paid to the Loan Administrator on the next
anniversary of the Closing Date shall be increased by the difference.

                  (iii)    Fee for Additional Services. In the event that a
Requesting Party requests that the Loan Administrator provide any of the
services described in Sections 8.1(b)(ix) and (x), the Loan Administrator's fee
for each of such services shall be equal to the product of (A) the total number
of hours actually worked performing such service, as set forth in a statement to
be delivered by the Loan Administrator to the party at whose expense such
service was performed, and (B) the agreed upon hourly rate charged for such
services in accordance with the rate schedule attached as Schedule 2.8
(increased annually on each anniversary of the Closing Date by not more than
[...***...]%). For the avoidance of doubt, the parties acknowledge and agree
that the fees set forth in this Section 2.8(e)(iii) shall not be taken into
account for purposes of determining the Total Costs of services provided by the
Loan Administrator in any year.

                  (f)      Guarantee Fees. The Borrower agrees to pay to the
Agent for the account of the Board on the Closing Date and annually thereafter

Counter-Guarantee Fees to the Agent for the account of each Counter-Guarantor on

                  (h)      Supplemental Facility Fees. The Borrower agrees to
pay to the Agent for the account of the Initial Lender the Supplemental Facility
Fees on the Closing Date and annually thereafter for so long as the Loan shall

                  (i)      Liquidity Fee. The Borrower agrees that if (i) at any
time after the Closing Date the Regulations are amended, modified or
supplemented such that the Board's consent shall be necessary in order for a
Lender to sell a participation in the Loan to any Person the sale of a
participation to which would not require the Board's consent if the Regulations
were then as in effect on the Closing Date and (ii) the Initial Lender seeks the
Board's consent to sell such a participation and such consent is not granted,
then the Initial Lender shall so notify the Borrower and the Agent and the
Borrower shall thereafter pay to the Agent for the account of the Initial Lender
a liquidity fee equal to [...***...]% per annum of the product of the principal
amount of the Loan outstanding from time to time held by the Initial Lender and
the Guaranteed Percentage, such liquidity fee to accrue from the date of such
notice from the Initial Lender and to be payable on each Interest Payment Date.

                  (j)      Distribution of Fees. On the Closing Date, and upon
its receipt thereof, the Agent shall distribute to the Person entitled thereto
each of the fees referred to in Section 2.8 payable on such date. Thereafter,
the Agent will distribute any and all fees payable under this Section 2.8 in
accordance with Section 2.9(d) or (e) hereof, as applicable.

                  (k)      All fees payable under this Section 2.8 shall be
non-refundable.

                  SECTION 2.9.      PAYMENTS AND COMPUTATIONS.

                  (a)      The Borrower shall make each payment hereunder

the day when due, in Dollars, to the Agent at Citibank, N.A., ABA #021000089,
Account No. 3041-9849, Account Name: Project Finance, Ref: America West Airlines
in immediately available funds without set-off or counterclaim. All payments in
respect of any Obligations shall at all times be made to the Agent, whether or
not a demand shall have been made or paid under the Board Guarantee. The 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 Agent after 12:00 noon (New York City time) shall be deemed to
be received on the next Business Day.

                  (b)      Each determination by the Agent of an interest rate
hereunder shall be conclusive and binding for all purposes, 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 made on the next
succeeding Business Day, and such extension of time shall in such case be
included in the computation of payment of interest or fees, as the case may be.

                  (d)      So long as no Event of Default under any of Sections
7.1(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 Agent shall apply all payments in
respect of any Obligations in the following order:

                  (i)      first, to pay any fees then due and payable under
                           Section 2.8(d) and (e) hereof to the Agent and the

                           basis;

                  (ii)     second, to pay interest then due and payable in
                           respect of the Loan to the Lenders, on a pro rata
                           basis (it being understood that following the Board's
                           honoring of a demand for payment in accordance with
                           the Board Guarantee, the Guaranteed Percentage
                           thereof shall be distributed to the Board and the
                           Non-Guaranteed Percentage thereof shall be
                           distributed to the Lenders, on a pro rata basis);

                           distributed to the Board and the Non-Guaranteed
                           Percentage thereof shall be distributed to the
                           Lenders, on a pro rata basis);

                           Section 2.8(f), (g), (h) and (i) hereof to the Board,
                           the Counter-Guarantors and the Initial Lender, as the
                           case may be, on a pro rata basis; and

                  (v)      fifth, to pay any other Obligations then due and
                           payable to the Agent, the Loan Administrator, the
                           Board, the Counter-Guarantors and the Lenders, on a
                           pro rata basis.

Notwithstanding the foregoing, to the extent that any amounts received by the
Agent constitutes interest accrued on any overdue principal of or interest on
the Loan in excess of the interest that would have accrued thereon at the
Applicable Rate, the Guaranteed Percentage of so much of such amount, if any, as
exceeds the interest that would have so

                                       29
<PAGE>
accrued at the Applicable Rate shall be distributed to the Board under clause
(ii) above and the balance shall be distributed to the Lenders under clause (ii)
above.

                  (e)      After the occurrence and during the continuance of an
Event of Default under any of Sections 7.1(a) (including any failure to pay all
amounts hereunder upon acceleration as a result of any other Event of Default),
(f) and (g), the Agent shall apply all payments in respect of any Obligations in
the following order:

                  (i)      first, to pay Obligations in respect of any expenses,
                           fees (other than any fees payable under clause (v)
                           below), indemnities or other sums owing hereunder not
                           referred to in clauses (ii) through (iv) below then
                           due to the Agent and the Loan Administrator, on a pro
                           rata basis;

                  (ii)     second, to pay Obligations in respect of any
                           expenses, fees (other than any fees payable under
                           clause (v) below), indemnities or other sums owing
                           hereunder not referred to in clauses (iii) and (iv)
                           below then due to the Board, the Lenders and the
                           Counter-Guarantors, on a pro rata basis;

                  (iii)    third, to pay interest then due and payable in
                           respect of the Loan to the Lenders, on a pro rata
                           basis (it being understood that following the Board's
                           honoring of a demand for payment in accordance with
                           the Board Guarantee, the Guaranteed Percentage
                           thereof shall be distributed to the Board and the
                           Non-Guaranteed Percentage thereof shall be
                           distributed to the Lenders, on a pro rata basis);

                  (iv)     fourth, to pay or prepay principal payments on the
                           Loan to the Lenders, on a pro rata basis (it being
                           understood that following the Board's honoring of a
                           demand for payment in accordance with the Board
                           Guarantee, the Guaranteed Percentage thereof shall be
                           distributed to the Board and the Non-Guaranteed
                           Percentage thereof shall be distributed to the
                           Lenders, on a pro rata basis); and

                  (v)      fifth, to pay any fees payable under Section 2.8(f),
                           (g), (h) and (i) hereof to the Board, the
                           Counter-Guarantors and the Initial Lender, as the
                           case may be, on a pro rata basis.

Notwithstanding the foregoing, to the extent that any amounts received by the
Agent constitutes interest accrued on any overdue principal of or interest on
the Loan in excess of the interest that would have accrued thereon at the
Applicable Rate, the Guaranteed Percentage of so much of such amount, if any, as
exceeds the interest that would have so accrued at the Applicable Rate shall be
distributed to the Board under clause (iii) above and the balance shall be
distributed to the Lenders under clause (iii) above.

<PAGE>
                  (f)      Upon the assignment to the Board of any Lender's
right, title and interest in and to its pro rata portion of the Guaranteed
Percentage of the principal of and interest on the Loan in accordance with the
Board Guarantee, the Board shall have the rights and privileges of a Lender with
respect to such payment (to the extent of the interests in the Loan so assigned
to the Board). Any statute or judicial decision to the contrary notwithstanding,
no payment by the Board or any Counter-Guarantor to the Agent or any Lender
under the Board Guarantee or any Counter-Guarantee, as the case may be, shall
reduce, discharge, satisfy, modify or terminate the corresponding payment or any
other obligation of Borrower under this Agreement or the Note, which shall
remain in full force and effect.

                  SECTION 2.10.     CERTAIN PROVISIONS GOVERNING THE NOTE.

                  (a)      Determination of Interest Rate. LIBOR for each
Interest Period for the Loan shall be determined by the Agent pursuant to the
procedures set forth in the definition of "LIBOR", and shall promptly thereafter
be notified to the Borrower and each Lender together with the Applicable
Interest Rate for such Interest Period.

                  (b)      Interest Rate Unascertainable, Inadequate or Unfair.
In the event that: (i) the Agent determines that 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; or (ii) the Requisite Lenders notify
the Agent that the LIBOR for any Interest Period will not adequately reflect the
cost to the relevant Lenders of making or maintaining the Loan for such Interest
Period, the Agent shall forthwith so notify the Borrower, the Board and the
Lenders, whereupon during the 30 days following the date of any such notice
given to the Borrower, the Agent, the Board and the Borrower 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 Loan (the
"Substitute Basis"). If within the 20 days following the date of any such notice
to the Borrower, the Agent and the Borrower 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 20 days from the date of such notice, the Agent and
the Borrower shall have failed to agree upon a Substitute Basis, then the Agent
(upon instructions from the Requisite Lenders) shall certify in writing to the
Borrower (such certification to be conclusive and binding on all of the parties
hereto absent manifest error) the interest rate at which such Lenders are
prepared to maintain their portion of the Loan for such Interest Period, it
being understood that such Lenders' interest rate shall be at 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 Loan for such
Interest Period. If no Substitute Basis is established, upon receipt of notice
of the interest rates at which the Requisite Lenders are prepared to maintain
their respective portion of the Loan, the Borrower shall have the right
exercisable upon ten Business Days' prior notice to the Lenders and the Board
through the Agent (i) to continue to borrow the Loan at the interest rate so
advised by the 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 Loan
together with accrued but unpaid interest thereon

                                       31
<PAGE>
at the interest rate certified in writing by the Requisite Lenders as provided
above and all other amounts due under the Loan Documents, whereupon the Loan
shall become due and payable on the date specified by the Borrower in such
notice.

                  (c)      Increased Costs. If at any time any Lender or
Counter-Guarantor shall determine that the introduction of or any change after
the date hereof in or in the interpretation of any law, treaty or governmental
rule, regulation or order or the compliance by such Lender or Counter-Guarantor,
with any guideline, request or directive after the date hereof from any central
bank or other Governmental Authority (whether or not having the force of law),
there shall be any increase in the cost to such Lender or Counter-Guarantor of
agreeing to make or making, funding, guaranteeing or maintaining any portion of
the Loan or its Counter-Guarantee (except in respect of Taxes based on the
overall net income of such Lender or Counter-Guarantor), then the Borrower shall
from time to time, upon demand (which demand shall be accompanied by a statement
setting forth the basis for such demand and a calculation of the amount thereof
in reasonable detail) by such Lender or Counter-Guarantor, as the case may be
(with a copy of such demand to the Agent), pay to the Agent for the account of
such Lender or Counter-Guarantor, as the case may be, additional amounts
sufficient to compensate such Lender or Counter-Guarantor, as the case may be,
for such increased cost. A certificate as to the amount of such increased cost,
submitted to the Borrower and the Agent by such Lender or Counter-Guarantor, as
the case may be, shall be conclusive and binding for all purposes, absent
manifest error.

                  (d)      Illegality. Notwithstanding any other provision of
this Agreement, if any Lender determines that the introduction 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 shall make it unlawful, or any central
bank or other Governmental Authority shall assert that it is unlawful, for such
Lender to continue to fund or maintain its portion of the Loan, then, on notice
thereof by such Lender to the Borrower through the Agent, the obligation of such
Lender to continue to fund or maintain its portion of the Loan shall be
terminated and the Borrower 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 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 Borrower pursuant to Section 2.7, the Borrower shall
compensate each Lender or each Counter-Guarantor, upon demand, for all 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 Counter-Guarantor 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 or its Counter-Guarantee, but excluding Taxes based
on the overall net income of such Lender or Counter-Guarantor) which that Lender
or Counter-

                                       32
<PAGE>
Guarantor, as the case may be, may sustain (i) if for any reason the proposed
Borrowing does not occur on a date specified therefor in the Notice of Borrowing
given by a Borrower, (ii) if for any reason any portion of the Loan is prepaid
(including mandatorily pursuant to Section 2.6 or this Section 2.10) or payment
made with respect to a Counter-Guarantee on a date which is not the last day of
the applicable Interest Period, or (iii) as a consequence of any failure by a
Borrower to repay any portion of the Loan or make payment with respect to a
Counter-Guarantee when required by the terms hereof or by such
Counter-Guarantee. The Lender or Counter-Guarantor making demand for such
compensation shall deliver to the Borrower (with a copy to the Agent)
concurrently with such demand a written statement as to such losses, expenses
and liabilities, and this statement shall be conclusive as to the amount of
compensation due to that Lender or Counter-Guarantor, as the case may be, absent
manifest error, and such compensation shall be paid to the Agent for the account
of such Lender or Counter-Guarantor, as the case may be.

                  SECTION 2.11.     CAPITAL ADEQUACY. If at any time any Lender
or Counter-Guarantor determines that (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 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 Counter-Guarantor's (or any
corporation controlling such Lender's or Counter-Guarantor's) capital as a
consequence of its obligations hereunder (other than as a result of changes in
Taxes based on the overall net income of such Lender or Counter-Guarantor) to a
level below that which such Lender or Counter-Guarantor, as the case may be, or
such corporation could have achieved but for such adoption, change, compliance
or interpretation, then, upon demand from time to time by such Lender or
Counter-Guarantor, as the case may be (with a copy of such demand to the Agent),
the Borrower shall pay to the Agent for the account of such Lender or
Counter-Guarantor, as the case may be, from time to time as specified by such
Lender or Counter-Guarantor, as the case may be, additional amounts sufficient
to compensate such Lender for such reduction. A certificate as to such amounts
submitted to the Borrower and the Agent by such Lender or Counter-Guarantor, as
the case may be, shall be conclusive and binding for all purposes absent
manifest error.

                  SECTION 2.12.     TAXES.

                  (a)      Except as otherwise provided in Section 10.2, any and
all payments by the Borrower 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, the Loan Administrator, each Counter-Guarantor, each Participant
and the Agent taxes measured by its net income, and franchise taxes imposed on
it, by the jurisdiction under the laws of which such Lender, the Loan
Administrator, such Counter-Guarantor, such Participant or the Agent (as the
case may be) is organized, (ii) in the case of each Lender and each Participant,
taxes measured by its net income, and franchise taxes imposed on it,

                                       33
<PAGE>
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 Counter-Guarantor, net income and franchise taxes imposed by
the jurisdiction to which the Borrower is directed to make payments to the
Counter-Guarantor pursuant to the Loan Documents, (iv) in the case of each
Lender, the Loan Administrator, each Participant, each Counter-Guarantor and the
Agent, Taxes imposed as a result of such Person failing to comply with its
obligations under Section 2.12(g) or 2.12(h) and (v) in the case of each Lender,
the Loan Administrator, each Participant, each Counter-Guarantor and the Agent
that is a party hereto, Counter-Guarantor or Participant, as the case may be, on
the Closing Date, United States federal withholding taxes unless imposed as a
result of a change in applicable law, including income tax conventions, after
the Closing Date (all such non-excluded Taxes being hereinafter referred to as
"Indemnified 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, the Loan Administrator, any Counter-Guarantor or the 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 2.12) such Lender, the Loan Administrator, such Counter-Guarantor
or the 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 Borrower shall make
such deductions, and (iii) the Borrower shall pay the full amount deducted to
the relevant taxing authority or other authority in accordance with applicable
law.

                  (b)      If any Taxes (other than Taxes imposed as a result of
the failure of the Counter-Guarantor to comply with its obligations under
Section 2.12(g)) shall be required by law to be deducted from or in respect of
any sum payable under any Counter-Guarantee to any Counter-Guarantor
("Counter-Guarantee Taxes"), (i) the Agent shall make such deductions and shall
so notify the Borrower (such notice shall be accompanied by a statement setting
forth the basis for such deductions and a calculation of the amount thereof in
reasonable detail), (ii) the Agent shall pay the full amount deducted to the
relevant taxing authority or other authority in accordance with applicable law,
and (iii) the Borrower shall pay to such Counter-Guarantor such amounts as may
be necessary so that after making all required deductions (including deductions
applicable to additional sums payable under this Section 2.12) such
Counter-Guarantor receives an amount equal to the sum it would have received had
no such deductions been made. Further, if any Taxes are required by law to be
deducted from or in respect to any sum payable under any Counter-Guarantee by
any Counter-Guarantor to the Agent, any Lender or any Participant and such
Counter-Guarantor in accordance with the terms of its Counter-Guarantee pays
such amounts as may be necessary so that after making all required deductions
the Agent, such Lender or such Participant, as the case may be, receives an
amount equal to the sum it would have received had no such deduction been made,
the Borrower shall pay the amount thereof to the Agent for the account of such
Counter-Guarantor (together with any additional amounts such that the
Counter-Guarantor receives, after deduction for all Taxes required to be
withheld, the amount so paid by the Counter-Guarantor).

                                       34
<PAGE>
                  (c)      In addition, the Borrower agrees 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 made under any Loan Document or
Counter-Guarantee or from the execution, delivery or registration of, or
otherwise with respect to, any Loan Document or Counter-Guarantee (collectively,
"Other Taxes") to the Agent for the account of the affected party.

                  (d)      The Borrower will indemnify each Lender, the Agent,
the Loan Administrator and each Counter-Guarantor for the full amount of
Indemnified Taxes, Counter-Guarantee Taxes or Other Taxes (including any Taxes
imposed by any jurisdiction on amounts payable under this Section 2.12) paid by
such Lender, the Loan Administrator, the Agent or Counter Guarantor (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 Agent for account of the relevant Lender, the Loan Administrator, the
relevant Counter-Guarantor or the Agent, as the case may be, within 30 days from
the date such Lender, the Loan Administrator, such Counter-Guarantor or the
Agent (as the case may be) makes written demand therefor (with a copy to the
Agent if made by a Lender, the Loan Administrator or Counter-Guarantor and
accompanied by a statement setting forth the basis for such taxation and the
calculation of the amount thereof in reasonable detail).

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

                  (f)      Without prejudice to the survival of any other
agreement of the Borrower hereunder, the agreements and obligations of the
parties contained in this Section 2.12 shall survive the payment in full of the
Obligations.

                  (g)      Each Lender, each Counter-Guarantor, each
Participant, the Loan Administrator and the Agent that is a Non-U.S. Person and
that is entitled at such time to an exemption from United States withholding
tax, or that is subject to such tax at a reduced rate under an applicable tax
treaty, shall, on or prior to the Closing Date or on or prior to the date of the
Assignment and Acceptance pursuant to which it becomes a Lender or on or prior
to the date such Person becomes a Counter-Guarantor, a Participant, the Loan
Administrator or the Agent, as applicable, and from time to time thereafter if
requested by the Agent, a Counter-Guarantor or the Borrower, provide the Agent
and the Borrower, and, in the case of each Lender, each Participant and the
Agent, provide each Counter-Guarantor, with two completed copies of either IRS
Form W-8BEN or W-8ECI or other applicable form, certificate or document
prescribed by the IRS certifying as to such Non-U.S. Person's entitlement to
such exemption from United States withholding tax or reduced rate with respect
to all payments to be made to such Non-U.S. Person under the Loan Documents. In
addition, each Lender, each Counter-Guarantor, each

                                       35
<PAGE>
Participant, the Loan Administrator and the Agent that is a Non-U.S. Person, as
the case may be, shall deliver to the Borrower and the Agent, and, in the case
of each Lender, each Participant and the Agent, deliver to each
Counter-Guarantor, notice of any event (other than a change in applicable law,
including income tax conventions) requiring a change in the most recent form
previously delivered by such Person to the Borrower and the Agent or the
Counter-Guarantors, as the case may be. Unless the Agent and the Borrower have
received forms or other documents satisfactory to them indicating that payments
under the Loan Documents or Counter-Guarantee 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 Agent or the Borrower shall,
notwithstanding the provisions of Section 2.12(a), (b) and (d) and without
impairing any obligation of the Borrower under this Section 2.12 with respect to
such tax, withhold such United States withholding taxes from such payments at
the appropriate rate.

                  (h)      Any Lender claiming any additional amounts payable
pursuant to this Section 2.12 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.

                  (i)      Each Participant will be entitled to the benefits and
subject to the requirements of this Section 2.12 to the same extent as if such
Person were a Lender.

                                   ARTICLE IV

                         REPRESENTATIONS AND WARRANTIES

                  To induce the other parties to enter into this Agreement and
to induce the Counter-Guarantors to enter into their respective
Counter-Guarantees, the Borrower represents and warrants to each other party
hereto and to each Counter-Guarantor that, on and as of the Closing Date (the
Borrower and Holdings are each referred to as an "Obligor" and collectively
referred to as the "Obligors"):

                  SECTION 4.1.      ORGANIZATION, POWERS, QUALIFICATION, GOOD
STANDING, BUSINESS, SUBSIDIARIES, THE ACT AND THE REGULATIONS.

                  (a)      Each Obligor is a corporation duly organized, validly
existing and in good standing under the laws of the State of Delaware. Each
Obligor has all requisite corporate power and authority to own and operate its
properties, to carry on its business as now conducted and as proposed to be
conducted, to enter into the Loan Documents to which it is a party and to carry
out the transactions contemplated hereby and thereby.

                  (b)      Each Obligor is qualified to do business and in good
standing in every jurisdiction where its assets are located and wherever
necessary to carry out its business and operations, except in jurisdictions
where the failure to be so qualified or in good standing would not in the
reasonable determination of such Obligor be expected to impair the ability of
such Obligor to perform its payment or other material obligations under the Loan
Documents to which it is a party. The Borrower is an "air carrier" within the
meaning of the Act and holds a certificate under Sections 41102(a)(1) and 41103
of Title 49. The Borrower is a "citizen of the United States" as defined in
Section 40102(a)(15) of Title 49 (a "United States Citizen") and holds an air
carrier operating certificate issued pursuant to Chapter 447 of Title 49 for
aircraft capable of carrying 10 or more individuals or 6,000 pounds or more of
cargo. The Borrower possesses all necessary certificates, franchises, licenses,
permits, rights and concessions and consents which are material to the operation
of the routes flown by it and the conduct of its business and operations as
currently conducted.

                  (c)      All of the Subsidiaries of the Obligors as of the
Closing Date are identified in Schedule 4.1 annexed hereto, as said Schedule 4.1
may be supplemented from time to time pursuant to the provisions of Section
5.l(xi). Each of the Subsidiaries of the Borrower identified in Schedule 4.1
annexed hereto (as so supplemented) is a corporation duly organized, validly
existing and in good standing under the laws of its respective jurisdiction of
incorporation set forth therein, has all requisite corporate power and authority
to own and operate its properties and to carry on its business as now conducted
and as proposed to be conducted, and is qualified to do business and in good
standing in every jurisdiction where its assets are located and wherever
necessary to carry out its business and operations, in each case except where
failure to be so qualified or in good standing or a lack of such corporate power
and authority would not in the

                                       41
<PAGE>
reasonable determination of the Borrower be expected to impair the ability of
the Borrower to perform its payment or other material obligations under the Loan
Documents. Schedule 4.1 annexed hereto (as so supplemented) correctly sets forth
the ownership interest of the Obligors and each of their Subsidiaries in each of
the Subsidiaries identified therein.

                  (d)      The Borrower is an "eligible borrower" within the
meaning of the Act and the Regulations, it does not have any outstanding
delinquent Federal debt (including tax liabilities), and the Application, the
Loan and the transactions contemplated hereby (assuming each Initial Lender is
an Eligible Lender) comply with the requirements of the Act and the Regulations.

                  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.

                  (b)      The execution, delivery and performance by each
Obligor of the Loan Documents and the agreements effecting the Concessions to
which it is a party and the consummation of the transactions contemplated by the
Loan Documents and the agreements effecting the Concessions to which it is a
party do not and will not (i) violate any provision of any law or any
governmental rule or regulation applicable to such Obligor or any of its
Subsidiaries, the Certificate or Articles of Incorporation or Bylaws of such
Obligor or any of its Subsidiaries or any order, judgment or decree of any court
or other agency of government binding on such Obligor or any of its
Subsidiaries, (ii) 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, (iii) result in or require the creation
or imposition of any Lien upon any of the properties or assets of such Obligor
or any of its Subsidiaries, or (iv) 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 Closing Date and have been disclosed in
writing to the Agent, each Initial Lender, each Counter-Guarantor and the Board.

                  (c)      The execution, delivery and performance by each
Obligor of 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 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.

                  (d)      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

                                       42
<PAGE>
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).

                  SECTION 4.3.      FINANCIAL CONDITION. Each Obligor has
heretofore delivered to the Lenders and the Counter-Guarantors, at the request
of any of them, the following financial statements and information: (i) the
audited consolidated balance sheets of such Obligor as at December 31, 2000, and
the related consolidated statements of income, stockholders' equity and cash
flows of such Obligor for the Fiscal Year then ended and (ii) the unaudited
consolidated balance sheet of such Obligor as at September 30, 2001 and the
related unaudited statements of income, stockholders' equity and cash flows of
such Obligor for the nine months then ended. All such consolidated statements
were prepared in conformity with GAAP and fairly present the consolidated
financial position of such Obligor as at the respective dates thereof and the
consolidated results of operations and cash flows of such Obligor for each of
the periods then ended subject, in the case of the unaudited consolidated
statements, to year-end audit and adjustments. Except as disclosed in writing to
the Agent and the Counter-Guarantors prior to the date of this Agreement,
neither Obligor has any material contingent liability or liability for taxes,
long-term lease or unusual forward or long-term commitment that is not reflected
in the foregoing consolidated financial statements (or, in the case of the
Borrower, in the most recently delivered consolidated financial statements
delivered pursuant to Section 5.1(i)(a) or (ii)) or the notes thereto and which
in any such case is material in relation to the business, operations,
properties, assets or condition (financial or otherwise) of such Obligor or,
with respect to the initial borrowing hereunder only, the prospects of the
Borrower.

                  SECTION 4.4.      NO MATERIAL ADVERSE CHANGE; NO RESTRICTED
PAYMENTS. Since November 13, 2001, no material adverse change has occurred in
the business, condition (financial or otherwise), operations, prospects,
performance, or properties of either Obligor or in the Borrower's ability to
repay the Loan or with respect to any of the matters covered by the
representations and warranties made in the Borrower's Application. Since
November 13, 2001, neither the Borrower nor any of its Subsidiaries has directly
or indirectly declared, ordered, paid or made, or set apart any sum or property
for, any Restricted Payment or agreed to do so except as would have been
permitted by Section 6.3, as if such Section were in effect at all times after
November 13, 2001 (except that for purposes of this Section 4.4 the terms
"Default" and "Event of Default" therein shall exclude the Disclosed Defaults).

                  SECTION 4.5.      TITLE TO PROPERTIES; LIENS. Each Obligor and
its 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,

                                       43
<PAGE>
in the case of the Borrower, 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. There are no
actions, suits, proceedings, arbitrations or governmental investigations
(whether or not purportedly on behalf of either 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
Borrower, threatened against or affecting either Obligor or any of its
Subsidiaries or any property of either Obligor or any of its Subsidiaries that,
individually or in the aggregate, if adversely determined, could in the
reasonable determination of the Borrower be expected to impair the ability of
such Obligor to perform its payment or other material obligations under the Loan
Documents to which it is a party or to otherwise have a material adverse effect
on the business, condition (financial or otherwise), operations, prospects,
performance or properties of such Obligor or any of its Subsidiaries or to
challenge the legality, validity or binding effect of any Loan Document
including, without limitation, this Agreement. Neither Obligor nor any of its
Subsidiaries is (i) in violation of any applicable laws that, individually or in
the aggregate, could in the reasonable determination of the Borrower be expected
to impair the ability of such Obligor to perform its payment or other material
obligations under the Loan Documents to which it is a party or (ii) subject to
or in default with respect to any final judgments, writs, injunctions, decrees,
rules or regulations of any court or any federal, state, municipal or other
governmental department, commission, board, bureau, agency or instrumentality,
domestic or foreign, that, individually or in the aggregate, could in the
reasonable determination of the Borrower be expected to impair the ability of
such Obligor to perform its payment or other material obligations under the Loan
Documents to which it is a party.

                  SECTION 4.7.      PAYMENT OF TAXES. Except to the extent
permitted by Section 5.3, all federal income tax returns and other material tax
returns and reports of each Obligor and its Subsidiaries required to be filed by
any of them have been timely filed (or extensions have been obtained with
respect thereto), and all federal income taxes and material Taxes upon each
Obligor and its Subsidiaries and upon their respective properties, assets,
income, businesses and franchises which are due and payable have been paid
before any penalty, fine or interest accrues thereon or are being contested in
good faith through appropriate proceedings and with respect to which an adequate
reserve has been established by the Borrower to the extent required by GAAP.
Except as disclosed in Schedule 4.7, there are no closing, settlement or similar
agreements with respect to Taxes of any material amount between any Obligor and
any taxing agency or authority.

                  SECTION 4.8.      PERFORMANCE OF AGREEMENTS; MATERIALLY
ADVERSE AGREEMENTS.

                  (a)      Neither Obligor nor any of its Subsidiaries is in
default in the performance, observance or fulfillment of any of the material
obligations, covenants or conditions contained in any of its Contractual
Obligations, and no condition exists that, with the giving of notice or the
lapse of time or both, would constitute such a default, except for the Disclosed
Defaults which will be cured after giving effect to the Borrowing and the
application of the proceeds therefrom.

                  (b)      Neither Obligor nor any of its Subsidiaries is a
party to or is otherwise subject to any agreements or instruments or any charter
or other internal restrictions which, individually or in the aggregate, could in
the reasonable determination of the Borrower be expected to impair the ability
of such Obligor to perform its payment or other material obligations under the
Loan Documents to which it is a party.

                  SECTION 4.9.      GOVERNMENTAL REGULATION. Neither Obligor nor
any of its Subsidiaries is subject to regulation under the Public Utility
Holding Company Act of 1935, the Federal Power Act, the Interstate Commerce Act
or the Investment Company Act of 1940 or under any other federal or state
statute or regulation which may limit its ability to incur Indebtedness or which
may otherwise render all or any portion of the Obligations unenforceable.

                  SECTION 4.10.     SECURITIES ACTIVITIES. Neither the Borrower
nor any of its Subsidiaries owns or is engaged principally, or as one of its
important activities, in the business of extending credit for the purpose of
purchasing or carrying any Margin Stock, nor shall any proceeds of the Loan be
used to purchase or carry Margin Stock or to extend credit to any Person for the
purpose of purchasing or carrying any Margin Stock in a manner that violates or
causes a violation of Regulations T, U or X of the Board of Governors of the
Federal Reserve System or any other regulation of such Board.

                  SECTION 4.11.     EMPLOYEE BENEFIT PLANS. Each Plan maintained
by the Borrower or an ERISA Affiliate is in compliance in all material respects
with all applicable laws. Except in such instances where an omission or failure
would not in the reasonable determination of the Borrower impair the ability of
the Borrower to perform its payment or other material obligations under the Loan
Documents (a) all returns, reports and notices required to be filed with any
regulatory agency with respect to any Plan have been filed timely and (b)
neither the Borrower nor any ERISA Affiliate has failed to make any contribution
or pay any amount due or owing as required by the terms of any Plan. There are
no pending or, to the best of the Borrower's knowledge, threatened claims,
lawsuits, investigations or actions (other than routine claims for benefits in
the ordinary course) asserted or instituted against the assets of any Plan or
its related trust or against any fiduciary of a Plan with respect to the
operation of such Plan that are likely to result in liability of the Borrower
that in the reasonable determination of the Borrower would impair the ability of
the Borrower to perform its payment or other

material obligations under the Loan Documents. Except in such instances where an
omission or failure would not in the reasonable determination of the Borrower
impair the ability of the Borrower to perform its payment or other material
obligations under the Loan Documents, each Plan maintained by the Borrower or an
ERISA Affiliate that is intended to be "qualified" within the meaning of section
401(a) of the Internal Revenue Code is, and has been during the period from its
adoption to date, so qualified, both as to form and operation and all necessary
governmental approvals, including a favorable determination as to the
qualification under the Internal Revenue Code of such Plan and each amendment
thereto, have been or will be timely obtained. Neither the Borrower nor any
ERISA Affiliate has engaged in any prohibited transaction, within the meaning of
section 406 of ERISA or section 4975 of the Internal Revenue Code, in connection
with any Plan which could result in liability of the Borrower that would in the
reasonable determination of the Borrower impair the ability of the Borrower to
perform its payment or other material obligations under the Loan Documents.
Neither the Borrower nor any ERISA Affiliate has any contingent liability with
respect to any post-retirement benefits under a welfare benefit plan as defined
in ERISA other than a liability for continuation coverage described in Part 6 of
Title I of ERISA, except where such liability could not in the reasonable
determination of the Borrower be expected to impair the ability of the Borrower
to perform its payment or other material obligations under the Loan Documents.
Neither the Borrower nor any ERISA Affiliate maintains, has established or has
ever participated in a multiple employer welfare benefit arrangement within the
meaning of ERISA except to the extent that such participation would not in the
reasonable determination of the Borrower be expected to impair the ability of
the Borrower to perform its payment or other material obligations under the Loan
Documents. The Borrower has not incurred any potential liability with respect to
a multiemployer plan, as defined in section 3(37) of ERISA or a plan described
in section 4063(a) of ERISA except to the extent that such liability would not
in the reasonable determination of the Borrower be expected to impair the
ability of the Borrower to perform its payment or other material obligations
under the Loan Documents. Neither the Borrower nor any ERISA Affiliate has
incurred any liability under Title IV of ERISA that has not been satisfied, and
no condition exists that could reasonably be expected to result in the Borrower
or an ERISA Affiliate incurring any liability under Title IV of ERISA that would
in the reasonable determination of the Borrower impair the ability of the
Borrower to perform its payment or other material obligations under the Loan
Documents.

      SECTION 4.12. ENVIRONMENTAL PROTECTION.

      (a) All Facilities and operations of each Obligor and its Subsidiaries
are, and have been to the Borrower's knowledge, in compliance with all
Environmental Laws except for any noncompliance which, individually or in the
aggregate, could not in the reasonable determination of the Borrower be expected
to impair the ability of the Borrower to perform its payment or other material
obligations under the Loan Documents.

      (b) There are no, and have been no, conditions, occurrences, or Hazardous
Materials Activity (a) arising at any Facilities or, to the knowledge of the
Borrower, at any other location or (b) arising in connection with the operations
of the Borrower or its Subsidiaries (including the transportation of Hazardous
Materials in accordance with applicable regulations), which conditions,
occurrences or Hazardous Materials Activity could reasonably be expected to form
the basis of an Environmental Claim against the Borrower or any of its
Subsidiaries and which, individually or in the aggregate, could in the
reasonable determination of the Borrower be expected to impair the ability of
the Borrower to perform its payment or other material obligations under the Loan
Documents.

      (c) There are no pending or, to the Borrower's knowledge, threatened
Environmental Claims against the Borrower or its Subsidiaries, and the Borrower
and its Subsidiaries have received no notices, inquiries, or requests for
information with respect to any Environmental Claims which in either case are
reasonably likely to be adversely determined and could individually or in the
aggregate in the reasonable determination of the Borrower be expected to impair
the ability of the Borrower to perform its payment or other material obligations
under the Loan Documents.

      (d) Except as disclosed to the Agent, the Board, the Counter-Guarantor and
the Lenders in writing on or prior to the Closing Date, the Borrower is not
currently operating or required to be operating under any compliance order,
schedule, decree or agreement, any consent decree, order or agreement, and/or
any corrective action decree, order or agreement issued or entered into under
any Environmental Law the failure to comply with which could individually or in
the aggregate in the reasonable determination of the Borrower be expected to
impair the ability of the Borrower to perform its payment or other material
obligations under the Loan Documents.

      SECTION 4.13. SOLVENCY. After giving effect to the Borrowing and to the
application of the proceeds therefrom, each Obligor is and, upon the incurrence
of any Obligations by the Borrower on any date on which this representation is
deemed made, will be, Solvent.

contained in this Agreement, the Application or in any other document,
certificate or written statement furnished to the Board, the Agent, the Lenders

with the transactions contemplated by this Agreement contains any untrue
statement as and when made, or as any of such representations and warranties may
be made from time to time in accordance with this Agreement and the other Loan
Documents. Any projections and pro forma financial information contained in the
Application are based upon good faith estimates and assumptions believed by the
Borrower to be reasonable at the time made, it being recognized by the Board,
the Agent and the Lenders that such projections as to future events are not to
be viewed as facts and that actual results during the period or periods covered
by any such projections may differ from the projected results. There are no
facts known to any Responsible Officer of the Borrower (other than matters of a
general economic nature) that, individually or in the aggregate, could in the
reasonable determination of the Borrower be expected to have a material adverse
effect on either Obligor and its Subsidiaries, taken as a whole or otherwise
impair the ability of either Obligor to perform its payment or other material
obligations under the Loan Documents to which it is a party.

      SECTION 4.15. 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
(either individually or in the aggregate) reasonably be expected to have a
material adverse effect on such Obligor and its Subsidiaries, taken as a whole
or otherwise impair the ability of such Obligor to perform its payment or other
material obligations under the Loan Documents to which it is a party.

      SECTION 4.16. CONCESSION AGREEMENTS. The Borrower has heretofore delivered
to the Board and the Agent a true and correct schedule identifying the
Concessions together with true and correct copies of the agreements effecting
the Concessions which have not been amended, supplemented or otherwise modified
prior to the date hereof. After giving effect to the Loan and application of the
proceeds therefrom, the Concessions are in full force and effect.

      SECTION 4.17. INDEBTEDNESS. Schedule 4.17 correctly sets forth the
consolidated Indebtedness of the Obligors and their Subsidiaries as of December
31, 2001. The Borrower has heretofore delivered to the Board and the Agent true
and correct copies of the Lease Indenture and the Term Loan Agreement, each as
amended, supplemented or otherwise modified through the date hereof.

                                   ARTICLE V

                                    COVENANTS

      To induce the other parties to enter into this Agreement and to induce the
Counter-Guarantors to enter into their respective Counter-Guarantees, the

replacements, betterments and improvements thereto, all as in the judgment of
the Borrower 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 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 Borrower
or such Subsidiary, as the case may be, desirable in the conduct of its
respective business and shall not impair the ability of the Borrower to perform
its payment or other material obligations under the Loan Documents. The 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
properties, to such an extent and against such risks, and will maintain
liability insurance, to the extent that property of a similar character is
usually so insured by companies engaged in a similar business and owning similar
properties in accordance with good business practice.

      SECTION 5.5. INSPECTION. The Borrower will, and will cause its
Subsidiaries to, permit any authorized representatives designated by the Agent,
any Lender, any Counter-Guarantor, the Loan Administrator or the Board to visit
and inspect any of the properties of the Borrower or any of its Subsidiaries,
including its and their financial and accounting records, and to make copies and
take extracts therefrom, and to discuss its and their affairs, finances and
accounts with its and their officers and independent public accountants, all
upon reasonable notice and at such reasonable times during normal business hours
and as often as may be reasonably requested; provided that so long as no Default
or Event of Default shall have occurred and be continuing, such inspection shall
not be disruptive to the Borrower's business, as reasonably determined by the
Borrower.

      SECTION 5.6. COMPLIANCE WITH LAWS, ETC. The Borrower 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 would
not in any case or in the aggregate in the reasonable determination of the
Borrower impair the ability of the Borrower to perform its payment or other
material obligations under the Loan Documents. The Borrower shall not conduct
any Hazardous Materials Activity at any Facility or at any other location in a
manner that does not comply with Environmental Laws.

      SECTION 5.7. BORROWER'S REMEDIAL ACTION REGARDING HAZARDOUS MATERIALS. To
the extent required by Environmental Laws, the Borrower will take, and will
cause each of its Subsidiaries to take, any and all necessary remedial action
(except to the extent that such remedial action is taken by other Persons
responsible for such remedial action through contractual arrangements with the
Borrower) in connection with the presence, storage, use, disposal,
transportation or Release of any Hazardous Materials

                                       55
<PAGE>
on, under or about any Facility in order to comply timely with all applicable
Environmental Laws and Governmental Authorizations except for such
non-compliance as would not in any case or in the aggregate in the reasonable
determination of the Borrower impair the ability of the Borrower to perform its
payment and other material obligations under the Loan Documents. In the event
the Borrower or any of its Subsidiaries undertakes any remedial action with
respect to any Hazardous Materials on, under or about any Facility, the Borrower
or such Subsidiary will conduct and complete such remedial action (or will cause
such action to be taken pursuant to contractual rights of the Borrower against
third parties) in compliance with all applicable Environmental Laws, and in
accordance with the policies, orders and directives of all federal, state and
local governmental authorities except when, and only to the extent that, the
Borrower's or such Subsidiary's liability for such presence, storage, use,
disposal, transportation or discharge of any Hazardous Materials is being
contested in good faith and by appropriate proceedings diligently conducted by
the Borrower or such Subsidiary or except for such non-compliance as would not
in any case or in the aggregate in the reasonable determination of the Borrower
impair the ability of the Borrower to perform its payment and other material
obligations under the Loan Documents.

      SECTION 5.8. FURTHER ASSURANCES. At any time or from time to time upon the
request of the Board, any Counter-Guarantor, the Loan Administrator or the
Agent, the Obligors will, at their expense, promptly execute, acknowledge and
deliver such further documents and do such other acts and things as the Board,
such Counter-Guarantor, the Loan Administrator or the Agent may reasonably
request in order to effect fully the purposes of the Loan Documents and to
provide for payment of the Obligations in accordance with the terms of this
Agreement, the Note and the other Loan Documents.

      SECTION 5.9. EMPLOYEE BENEFIT PLANS. The Borrower shall take such actions
as are reasonably practicable to ensure that the Plans with respect to which it
may have any liability are operated in material compliance with all applicable
laws, except to the extent that the failure to do so could not in the reasonable
determination of the Borrower be expected to impair the ability of the Borrower
to perform its payment or other material obligations under the Loan Documents.
Neither the Borrower nor a Subsidiary shall amend, adopt or terminate any Plan
unless such action could not in the reasonable determination of the Borrower be
expected to impair the ability of the Borrower to perform its payment or other
material obligations under the Loan Documents.

      SECTION 5.10. FAA MATTERS; CITIZENSHIP. The Borrower will at all times
hereunder be an "air carrier" within the meaning of the Act and hold a
certificate under 49 U.S.C. Section 41102(a)(1) as currently in effect or as may

hereunder be a United States Citizen holding an air carrier operating
certificate issued pursuant to Chapter 447 of the Act for aircraft capable of
carrying 10 or more individuals or 6,000 pounds or more of cargo. The Borrower
will possess and maintain all necessary consents, franchises, licenses,

                                       56
<PAGE>
permits, rights and concessions and consents which are material to the operation
of the routes flown by it and the conduct of its business and operations as
currently conducted.

      SECTION 5.11. BOARD GUARANTEE. The Borrower shall comply with all of the
terms, requirements and conditions applicable to it under the Act and the
Regulations, or as may otherwise be imposed by, or agreed with, the Board in
connection with the issuance of the Board Guarantee, and shall promptly furnish
the Board, the Loan Administrator and the Agent (with a copy to the
Counter-Guarantors) all such information as may be requested by the Board, the
Loan Administrator or the Agent in connection with the Board Guarantee. The
Borrower shall execute such documents and take such actions in furtherance of
its obligations under the Act and the Regulations as the Board, the Loan
Administrator or the Agent may request.

      SECTION 5.12. LOWER-TIER COVERED TRANSACTION. The Borrower agrees that in
the event that it enters into any "lower-tier covered transaction" (as such term
is defined in 31 C.F.R. Section 19.110, as amended or modified from time to time
and not excepted therefrom by 31 C.F.R. Section 19.200(c)) in respect of the
transactions contemplated hereunder, it will include the clause entitled
"Certificate Regarding Debarment, Suspension, Ineligibility and Voluntary
Exclusion - Lower Tier Covered Transactions" as set forth in Appendix B to Part
19 of title 31 of the C.F.R. in such "lower-tier covered transaction", and that
it will obtain a certification from the other Person or Persons party to such
"lower-tier covered transaction" to the effect that each such other Person (and
each "principal" thereof, as such term is defined in 31 C.F.R. Section 19.105,
as amended or modified from time to time) is not presently debarred, suspended,
proposed for debarment, declared ineligible, or voluntarily excluded from
participation in such transaction by any Federal department or agency, or an
explanation why such Person is unable to so certify. Further, Borrower agrees
that it will not enter into a "lower-tier covered transaction" with a Person who
has been proposed for debarment under 48 C.F.R. Section 9.4, debarred or
suspended unless granted an exception for such "lower-tier covered transaction"
pursuant to 31 C.F.R. Section 19.215.

      SECTION 5.13. AUDITS AND REVIEWS. The Borrower agrees to permit, and to
cooperate in the conduct of, such audits and reviews during the period the Loan
is outstanding and for three years thereafter, as the Board may deem
appropriate, by an independent auditor acceptable to the Board or the United
States Comptroller General. To the extent requested by the Board or the Loan
Administrator, the Borrower shall provide access to the officers and employees,
books, records, accounts, documents, correspondence, and other information of
the Borrower, its Subsidiaries, Affiliates, financial advisors, consultants and
independent certified accountants that the Board or the United States
Comptroller General considers necessary.

      SECTION 5.14. ADDITIONAL COLLATERAL. The Borrower shall use commercially
reasonable efforts to add to the collateral securing the loans under the Term
Loan Agreement in any instance when the Borrower would otherwise be required
under

                                       57
<PAGE>
the Term Loan Agreement to prepay such loans as a result of a borrowing base

Subsidiary shall reasonably and in good faith determine that such Affiliate
Transaction is fair and reasonable to the Borrower or such Subsidiary, as the

the Borrower under the Senior Notes. The amount of such Net Cash Proceeds
required to be applied (or to be committed to be applied) during such Fiscal

or a Wholly-Owned Subsidiary) and (ii) shall not permit any Subsidiary to issue
shares of its Capital Stock (other than directors' qualifying shares), or
securities convertible or exchangeable into, or options, warrants, rights or any
other interest with respect to, its Capital Stock to any Person other than to
the Borrower or a Wholly-Owned Subsidiary; provided, that the limitations of
this Section shall not apply to any transaction between or among the Borrower
and one or more direct or indirect Wholly-Owned Subsidiaries of the Borrower
whereby the Borrower merges, consolidates or otherwise combines with such
Wholly-Owned Subsidiary and pursuant to which all existing holders of Capital
Stock of the Borrower receive, upon conversion or otherwise in exchange for
securities owned by such holders, Capital Stock of a corporation which
immediately prior to such exchange is a Wholly-Owned Subsidiary, and which
securities have rights and preferences identical to those of the securities
replaced, so long as (a) immediately before and after giving effect to such
transaction no Default or Event of Default shall have occurred and be
continuing, (b) such transaction is otherwise in conformity with and not
prohibited by this Agreement and (c) immediately following such transaction, the
Borrower's credit rating is no lower than immediately prior thereto.

      SECTION 6.12. LIMITATION ON CREATION OF NEW SUBSIDIARIES. Neither Obligor
may create new Subsidiaries, except Wholly-Owned Subsidiaries and if (i) the
total assets of such Subsidiaries in the aggregate (other than single purpose
Subsidiaries created solely for the purpose of financing aircraft for use by the
Borrower) do not at any time exceed five percent (5%) of the consolidated total
assets of the Borrower, in each case determined in accordance with GAAP and (ii)
the Borrower complies with the provisions of Section 5.1(xi) hereof, but can
make Investments permitted under Section 6.2.

      SECTION 6.13. LIMITATIONS ON AMENDMENTS. Neither Obligor shall amend,
waive or modify, nor shall it consent to or request any amendment, waiver or
modification, of any of the material terms, conditions, representations and
covenants contained in any Indebtedness for borrowed money that (i) shortens the
final maturity date of such Indebtedness (without giving effect to any
amendment, waiver or modification, the "Initial Indebtedness"; and after giving
effect to any such amendment, waiver or modification, the "Amended
Indebtedness"), (ii) requires the acceleration of the final scheduled maturity
date and/or any principal payments, including but not limited to scheduled
payments and mandatory prepayments, and/or increases the principal amount
payable on any date (including, without limitation, pursuant to mandatory
prepayments) prior to the dates of analogous payments of such Initial
Indebtedness, (iii) provides for an interest rate applicable to such Amended
Indebtedness, plus the interest rate equivalent of all remaining fees and costs
associated with closing and servicing such

                                       64
<PAGE>
Amended Indebtedness higher than the greater of (x) (I) if such Amended
Indebtedness bears interest at a floating rate of interest, 105% of the average
remaining interest rate applicable to such Initial Indebtedness plus the average
remaining fees and costs associated with servicing such Initial Indebtedness, or
(II) if such Amended Indebtedness bears interest at a fixed rate of interest,
the amount calculated as the sum of clause (I) above plus the appropriate
fixed-for-floating swap rate for the Initial Indebtedness, and (y) 105% of the
average remaining "all in" interest expense for such Initial Indebtedness as
contemplated in the Business Plan. Neither Obligor shall agree to any amendment,
waiver or modification of the Concessions if, after giving effect to such
amendment, waiver or modification, the aggregate value of the Concessions as a
whole that the Borrower realizes and is scheduled to realize during the term of
the Loan would be reduced as a result of such amendments, waivers or
modifications by more than $60.0 million in the aggregate, as determined in good
faith by the Borrower. In connection with any amendment, waiver or modification
to the Concessions which reduce the value of the Concessions taken as a whole,
the Borrower shall provide the Board with an Officer's Certificate certifying
that such amendment, waiver or modification complies with the conditions of the
preceding sentence and, taken as a whole, are beneficial to the Borrower and
such reduction shall not have a material adverse effect on the Borrower's
ability to repay the Loan. The Obligors shall perform each of their material
obligations under the Lease Indenture and the Concessions, in each case strictly
in accordance with the terms thereof, and shall not reduce or agree to reduce
the exercise price of the convertible debentures issued under the Lease
Indenture to less than $12.00. The Borrower agrees to promptly notify the Agent,
the Board and the Counter-Guarantors of any default under the Lease Indenture or
the Concessions. Holdings may not issue convertible debentures under the Lease
Indenture in excess of $120 million, except that Holdings may issue up to (but
not more than) $30 million of additional convertible debentures under the Lease
Indenture, provided that for each $1.00 so issued the Borrower receives and
realizes during the term of the Loan concessions valued at at least $2.50.

      SECTION 6.14. NO FURTHER NEGATIVE PLEDGES. Except with respect to (a)
specific property encumbered to secure payment of particular Indebtedness or to
be sold pursuant to an executed agreement with respect to a permitted asset
sale, and (b) restrictions by reason of customary provisions restricting
assignments, subletting or other transfers contained in leases, licenses and
similar agreements entered into in the ordinary course of business (provided
that such restrictions are limited to the property or assets secured by such
Liens or the property or assets subject to such leases, licenses or similar
agreements, as the case may be), after the date hereof neither the Borrower nor
any of its Subsidiaries shall enter into any agreement prohibiting the creation
or assumption of any Lien upon any of its properties or assets, whether now
owned or hereafter acquired.

      SECTION 6.15. INCENTIVE EQUITY PLAN. Any employee stock options granted
under the America West 1994 Incentive Equity Plan on or prior to the Closing
Date shall not have been, and shall not be, repriced from the date of the
Borrower's initial Application for so long as the Loan shall remain
outstanding). For purposes of this Section 6.15, "repricing" shall mean any
repricing transaction required to be disclosed

                                       65
<PAGE>
under Item 402(i) of Regulation S-K under the Securities Act of 1933, as
amended. Neither Obligor shall award or pay any compensation to any officer,
director or employee who holds options that are subject to the restriction in
this Section 6.15 which is intended to off-set the effect of the repricing
restriction.

operating cash flow results, quarterly investment cash flows, net changes in
Borrower's cash position, debt covenant compliance and such other financial
matters as shall be reasonably requested in writing by a Requesting Party and
(b) an indicative credit rating of the Borrower; it being acknowledged and
agreed that the Loan Administrator may retain a sub-servicer reasonably
acceptable to the Requesting Party to provide these services, in which event,
the Loan Administrator shall not be in default of its obligations hereunder (x)
if the sub-servicer fails to comply with its obligations to provide the
quarterly financial reports or indicative credit rating of the Borrower
described herein so long as the Loan Administrator had exercised reasonable

                                       69
<PAGE>
care and good faith in providing the financial statements to the sub-servicer
and attempting to procure the report or indicative credit rating on behalf of
the Requesting Party, or (y) if the Loan Administrator is unable, after
exercising reasonable care and good faith, to retain a sub-servicer to provide
an indicative credit rating of the Borrower;

            (v) review the periodic reports and other reports which the Borrower

regarding such matters as are specifically identified in writing by such
Requesting Party with respect to such reports;

            (vi) at the written direction of a Requesting Party, give notices or
provide instructions on behalf of the Requesting Party to any Person under this

relevant inquiries of each such Person so as to respond to specific questions
from the Requesting Party regarding such Person's financial condition and
ability to perform its respective obligations under the other Loan Documents;

            (ix) at the direction and expense of the Requesting Party, procure
and coordinate the advice of professional advisers necessary for such Requesting
Party to perform its obligations and enforce its rights under the Loan

Requesting Party, take such other actions as may be reasonably requested in
writing by the Requesting Party in respect of the Loan and the Loan Documents,
such actions to be upon such terms and conditions as shall be mutually agreed to
by the Requesting Party and the Loan Administrator.

      (c) With respect to the Loan Administrator's responsibilities under
Sections 8.1(b) above, the Loan Administrator shall not be required to take any
action which exposes the Loan Administrator to liability or which is contrary to
this Agreement, any other Loan Document, the Board Guarantee or applicable law.
The execution and delivery of this Agreement by the Loan Administrator shall not
give rise to any implied duties or fiduciary obligations of the Loan
Administrator to any Requesting Party or any other Person. The Board hereby
acknowledges and agrees that the failure of the Loan

                                       70
<PAGE>
Administrator to perform any of its obligations hereunder shall not invalidate
or otherwise affect the Board Guarantee.

      (d) Except as permitted in subsection (b)(iv) above, the Loan
Administrator shall not be permitted to assign any of its obligations hereunder,
enter into sub-servicing agreements or otherwise delegate any of its duties
under this Agreement without the prior written consent of the Requisite Lenders
and the Board. The Loan Administrator hereby acknowledges and agrees that the
fees and expenses payable to any sub-servicer retained by it in accordance with
this Agreement shall be paid out of the fees payable by the Borrower to the Loan
Administrator under Section 2.8(e).

      (e) The Loan Administrator may retain legal counsel (including counsel for
the Loan Administrator), independent public accountants and other experts or
advisers as desirable to provide the services set forth in Section 8.1(b), and
shall be reimbursed by the Borrower for the reasonable associated costs and such
other reasonable expenses as the Loan Administrator shall incur in providing
such services. The Borrower shall be responsible for such costs and expenses
with respect to the services set forth in Section 8.1(b)(viii) hereof
(calculated in the manner set forth in Section 2.8(e)(iv)), and a Requesting
Party shall be responsible for the costs and expenses with respect to the
services set forth in Section 8.1(b)(ix) and (x) if requested by such Requesting
Party (calculated in the manner set forth in Section 2.8(e)(iv)).

      (f) In the event that any of the Lenders or the Board shall request that
the Loan Administrator provide additional services to it under Section 8.1(b)(x)
or which are otherwise outside the scope of the services to be provided by the
Loan Administrator hereunder, the Loan Administrator shall, to the extent it
agrees to provide such additional services to such party, be entitled to charge
such party such additional fees. Unless otherwise agreed to by such Person and
the Loan Administrator, the terms and conditions of this Article VIII shall
apply to the provision by the Loan Administrator of such additional services to
such party.

      SECTION 8.2. LOAN ADMINISTRATOR'S RELIANCE. (a) The Loan Administrator
shall be entitled to rely upon any note, notice, consent, certificate,
affidavit, letter, telegram, teletype message, facsimile transmission,
statement, order or other document in good faith 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
Administrator.

      (b) Neither the Loan Administrator nor any of its directors, officers,
agents or employees shall be liable to any Lender, the Board or any
Counter-Guarantor 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 or any other Loan Document, except for its or their own gross
negligence or willful misconduct. Without limitation of the generality of the
foregoing, the Loan Administrator: (i) may consult with legal counsel,
independent public accountants and other experts selected by it and shall not be
liable to any Lender or the Board for any action taken or omitted to be taken in
good faith

                                       71
<PAGE>
by it in accordance with the advice of such experts; (ii) except as provided in
Section 8.1(b) above, 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 Note or any other Loan Document on the part of Holdings or
the Borrower or to inspect the property (including the books and records) of
Holdings, the Borrower or any of their respective Subsidiaries; (iii) except as
otherwise provided in this Article VIII, shall not be responsible to any Lender
or the Board for the due execution, legality, validity, enforceability,
genuineness, sufficiency or value of this Agreement, the Note or any other Loan
Document, or any other instrument or document furnished pursuant thereto; and
(iv) shall incur no liability under or in respect to this Agreement, the Note 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) in good faith believed by it to be genuine and signed or sent by the
proper party or parties.

      (C) IN NO EVENT SHALL THE LOAN ADMINISTRATOR, ITS EMPLOYEES, OFFICERS,
DIRECTORS OR AGENTS BE LIABLE FOR CONSEQUENTIAL, SPECIAL, INDIRECT, INCIDENTAL,
PUNITIVE OR EXEMPLARY DAMAGES, COSTS, EXPENSES, OR LOSSES (INCLUDING, WITHOUT
LIMITATION, LOST PROFITS AND OPPORTUNITY COSTS). THE LENDERS AND THE BOARD AGREE
THAT THE LOAN ADMINISTRATOR, ITS EMPLOYEES, OFFICERS, DIRECTORS AND AGENTS SHALL
NOT BE LIABLE TO THE LENDERS AND THE BOARD FOR ANY ACTIONS, DAMAGES, CLAIMS,
LIABILITIES, COSTS, EXPENSES OR LOSSES IN ANY WAY ARISING OUT OF OR RELATING TO
THE PERFORMANCE OR NONPERFORMANCE OF SERVICES HEREUNDER OR UNDER ANY OTHER LOAN
DOCUMENT FOR AN AGGREGATE AMOUNT IN EXCESS OF THE FEES PAID BY THE LENDERS AND
THE BOARD TO THE LOAN ADMINISTRATOR IN PERFORMING THE SERVICES DESCRIBED HEREIN.
NO TERMS OF THIS AGREEMENT, OR ANY OTHER LOAN DOCUMENT SHALL BENEFIT OR CREATE
ANY RIGHT OR CAUSE OF ACTION IN OR ON BEHALF OF ANY PERSON OR ENTITY OTHER THAN
THE LENDERS AND THE BOARD. THE PROVISIONS OF THIS SUBSECTION SHALL APPLY
REGARDLESS OF THE FORM OF ACTION, DAMAGE, CLAIM, LIABILITY, COST, EXPENSE, OR
LOSS, WHETHER IN CONTRACT, STATUTE, TORT (INCLUDING, WITHOUT LIMITATION,
NEGLIGENCE), OR OTHERWISE.

      SECTION 8.3. INDEMNIFICATION. The Borrower, Holdings and each Requesting
Party (other than the Board) agrees to indemnify the Loan Administrator and its
directors, officers, employees, advisors and representatives from and against
any and all costs, losses, liabilities, claims, damages or expenses (excluding
Taxes) which may be incurred by or asserted or awarded against the Loan
Administrator in any way relating to or arising out of the services provided by
the Loan Administrator on behalf of and at the request of such Requesting Party
in connection with this Agreement or any action taken or omitted by the Loan
Administrator under this Agreement or any Loan Document or both on behalf of and
at the request of such Requesting Party; provided, however, that none of the
Borrower, Holdings or any Requesting Party shall be liable for any portion of

                                       72
<PAGE>
such liabilities, obligations, losses, damages, penalties, actions, judgments,
suits, costs, expenses or disbursements resulting from the Loan Administrator's
gross negligence or willful misconduct. Without limitation of the foregoing, and
to the extent that the Loan Administrator is not reimbursed therefore by the
Borrower under any Loan Document, any Requesting Party requesting the Loan
Administrator to take any action hereunder on its behalf agrees to reimburse the
Loan Administrator promptly upon demand (but in all events within 30 days after
written request) for any and all fees of the Loan Administrator, reasonable
out-of-pocket costs and expenses (including counsel fees) incurred by the Loan
Administrator in connection with the performance of the requested services
requested by such Requesting Party hereunder and under the Loan Documents;
provided that the Loan Administrator shall provide prompt written notice to the
Requesting Party (a) at such time as the Actual Costs for the services provided
by the Loan Administrator during any twelve month period beginning with the most
recent anniversary of the Closing Date exceed eighty percent (80%) of the amount
of fees actually paid by the Borrower to the Loan Administrator under Section
2.8(e)(i) for such period (including, for purposes of calculating the fees paid
by the Borrower in any such period, the amount of fees carried over in
accordance with Section 2.8(e)(ii) from a prior period in which the Actual Costs
were less than $[...***...]), and (b) of the Borrower's failure to pay any
outstanding fees, costs or expenses of the Loan Administrator. Except as
provided in the preceding sentence regarding reimbursement, in no event shall
the Board be obligated to indemnify the Loan Administrator or any of its
directors, officers, employees, advisors, representatives or any other party
under any circumstances.

      SECTION 8.4. SUCCESSOR LOAN ADMINISTRATOR. The Loan Administrator may
resign at any time by giving 30 days prior written notice thereof to the Lenders
and the Board and may be removed at any time with or without cause by the
Requisite Lenders and the Board; provided, however, that the Loan Administrator
shall continue to perform all Loan Administrator functions hereunder until a
successor Loan Administrator shall have been appointed. Upon any such
resignation or removal, the Requisite Lenders shall have the right to appoint a
successor Loan Administrator, subject to confirmation by the Board. If no
successor Loan Administrator shall have accepted such appointment within 120
days after the retiring Loan Administrator's giving of notice of resignation or
the removal of the Loan Administrator, the Loan Administrator may appoint a
successor Loan Administrator who shall be willing to accept such appointment.
Upon the acceptance of any appointment as Loan Administrator hereunder by a
successor Loan Administrator, such successor Loan Administrator shall thereupon
succeed to and become vested with all the rights, powers, privileges and duties
of the retiring or removed Loan Administrator, and the retiring or removed Loan
Administrator shall be discharged from its duties and obligations as Loan
Administrator under this Agreement. After any Loan Administrator's resignation
or removal hereunder as Loan Administrator the provisions of this Article VIII
shall inure to its benefit as to any actions taken or omitted to be taken by it
while it was Loan Administrator under this Agreement.

      SECTION 8.5. CONFLICT OF INTEREST. (a) The Lenders and the Board
acknowledge and agree that (i) there is an existing contract between the
Department of the Treasury and KPMG Consulting, LLC (a wholly-owned subsidiary
of the Loan

Administrator), dated November 26, 2001 under which KPMG Consulting, LLC
provides support for the Board's Air Carrier Loan Guarantee Program; (ii) the
Loan Administrator may at any time and from time to time be an Affiliate of the
Agent, any Lender, any Counter-Guarantor or any participant in the Loan; (iii)
in addition to serving as Loan Administrator under this Agreement, the Loan
Administrator may at any time and from time to time service, manage or enter
into other commercial arrangements with respect to other property, loans and
assets of the Agent, any Lender, any Counter-Guarantor or any participant in the
Loan (each a "Loan Administrator Relationship"); (iv) in the course of
conducting such activities or the services to be provided by it hereunder, or
both, the Loan Administrator may from time to time have conflicts of interest by
virtue of the Agent, any Lender, any Counter-Guarantor or any participant in the
Loan being an Affiliate of the Loan Administrator or by virtue of a Loan
Administrator Relationship or both; and (v) the Lenders and Board expressly
recognize that such conflicts of interest may arise, do hereby waive such
conflicts and agree that when such conflicts of interest arise the Loan
Administrator shall perform the services to be provided by it hereunder in a
professional, diligent and workmanlike fashion. The parties hereto further
acknowledge and agree that the Loan Administrator, in its capacity as Loan
Administrator, is not acting as an Affiliate of any of the parties hereto, and
the performance of the Loan Administrator obligations hereunder shall not affect
any right or remedy which the Agent, any Lender, any Counter-Guarantor or any
participant in the Loan may have under any Loan Document, any Counter-Guarantee
or the Board Guarantee whether or not any such Person is an Affiliate of the
Loan Administrator. Each Requesting Party expressly acknowledges and agrees that
at all times it shall take such action or omit to take such action hereunder
based on its own independent analysis of the relevant transaction and attendant
facts and circumstances.

      (b) Notwithstanding any provision herein to the contrary, if in connection
with the provision of Services, a conflict of interest shall exist that, in the
good faith opinion of the Loan Administrator, requires an arm's-length
negotiation between the Loan Administrator, on the one hand, and any Affiliate
of the Loan Administrator, Loan Administrator Relationship or a Requesting
Party, on the other hand, and the Loan Administrator believes it would not be
appropriate for the Loan Administrator to act on behalf of the Requesting Party
in connection with such matter, then the Loan Administrator shall withdraw from
acting as Loan Administrator in connection with the negotiation of the issue
giving rise to such conflict of interest by giving written notice to the
Requesting Party not more than ten (10) Business Days after it has made such
determination. In such event, the Requesting Party shall be entitled to appoint
an independent representative to act on its behalf and at its expense for
purposes of the matter giving rise to such conflict of interest, and the Loan
Administrator shall have no responsibility or liability to the Requesting Party
with respect to such matter. During the period of such independent
representative's appointment, the Loan Administrator shall continue to perform
its ordinary functions as Loan Administrator to the extent that the performance
of the Loan Administrator does not, in the reasonable opinion of the Requesting
Party, directly or indirectly affect the matter giving rise to the conflict of
interest.

      (a) it is duly incorporated and validly existing under the laws of its
jurisdiction of incorporation;

      (b) it has the corporate power and authority to execute, deliver and
perform its obligations under this Agreement, and this Agreement has been duly
authorized by it by all necessary corporate action;

      (c) no authorization, consent or approval of any governmental authority,
regulatory body or other Person is required for the due authorization,
execution, delivery or performance by it of this Agreement;

      (d) this Agreement has been duly executed and delivered by it and
constitutes a legal and binding obligation of it, enforceable against it in
accordance with its terms, except as enforceability may be limited by applicable
bankruptcy, insolvency, reorganization, moratorium or other similar laws now or
hereinafter in effect, relating to the enforcement of creditors' rights in
general and except as such enforceability may be limited by general principles
of equity (whether considered in a proceeding at law or in equity);

      (e) the execution, delivery and performance by it of this Agreement does
not violate any provision of any existing law or regulation or any material
agreement to which it is subject or to which it is a party or result in the
creation of any Lien;

      (f) it has all corporate power and governmental licenses, authorizations,
and consents and approvals required to carry on its business as now conducted,
except where the failure to have such licenses, authorizations, and consents and
approvals would not have a material adverse effect on its ability to perform its
duties under this Agreement; and

      (g) it will maintain and implement administrative and operating
procedures, and keep and maintain all documents, books, computer records and
other information reasonably necessary or advisable for the performance of the
services to be provided by it hereunder

                                   ARTICLE IX

                                    THE AGENT

      The parties hereto agree as follows:

      SECTION 9.1 AUTHORIZATION AND ACTION. Each Lender hereby appoints and
authorizes the Agent to take such action as administrative agent on its behalf
and to

                                       75
<PAGE>
exercise such powers under this Agreement and the Note as are delegated by such
Lender to it as Agent by the terms hereof and thereof, together with such powers
as are reasonably incidental thereto, and the Agent hereby accepts such
authorization and appointment. As to any matters not expressly provided for by
this Agreement and the Note or provided for with specific reference to this
Section 9.1 (including, without limitation, enforcement or collection of the
Note), the Agent shall not 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 Board or, if the Board Guarantee is no longer in full force and effect, the
Requisite Lenders and such instructions shall be binding upon all Lenders;
provided, however, that the Agent shall not be required to take any action which
exposes the Agent to liability or which is contrary to this Agreement, the Board
Guarantee, any Counter-Guarantee, any Counter-Guarantor Letter of Credit or the
Note or applicable law. As to any provisions of this Agreement under which
action may be taken or approval given by the Requisite Lenders or the Board or
both, as the case may be, the action taken or approval given by the Requisite
Lenders or the Board or both, as the case may be, shall be binding upon all
Lenders to the same extent and with the same effect as if each Lender had joined
therein. The 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 Agent.
The Agent may deem and treat the payee of the Note 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 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 the Note shall be conclusive and binding on any
subsequent holder, transferee or assignee of the Note.

      SECTION 9.2. AGENT'S RELIANCE, ETC. Neither the Agent nor any of its
directors, officers, agents or employees shall be liable to any Lender, the Loan
Administrator or the Board 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 Note or any other Loan Document, except for its or their own
gross negligence or willful misconduct. Without limitation of the generality of
the foregoing, the Agent: (i) may consult with legal counsel, independent public
accountants and other experts selected by it and shall not be liable to any
Lender, the Loan Administrator or the Board 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, the Loan Administrator or,
except as expressly provided in the Board Guarantee, the Board and shall not be
responsible to any Lender, the Loan Administrator or, except as expressly
provided in the Board Guarantee, the Board for any statements, warranties or
representations (whether oral or written) made in or in connection with this
Agreement, the Note 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 Note or any other Loan Document
on the part of Holdings or the Borrower or to inspect the property (including
the books and records) of Holdings, the Borrower or any of their respective
Subsidiaries; (iv) shall not be responsible to any

                                       76
<PAGE>
Lender, the Loan Administrator or the Board for the due execution, legality,
validity, enforceability, genuineness, sufficiency or value of this Agreement,
the Note 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 Note 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 Agent receives and accepts an
Assignment and Acceptance Agreement entered into by such Lender, as assignor,
and an eligible assignee as provided in Section 10.2 hereof.

      SECTION 9.3 AGENT AND AFFILIATES. If and so long as the Agent shall remain
a Lender, the Agent 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 Agent; and the term "Lender" or "Lenders" shall, unless otherwise expressly
indicated, include the Agent in its individual capacity. Unrelated to its role
as Agent as set forth herein, the Agent and its affiliates may accept deposits
from, lend money to, act as trustee under indentures of, and generally engage in
any kind of business with, the Borrower, Holdings, any of its Subsidiaries and
any Person who may do business with or own securities of the Borrower, all as if
it were not the Agent hereunder and without any duty to account therefor to the
Lenders.

      SECTION 9.4. REPRESENTATIONS OF THE LENDERS AND OF THE BOARD. Each Lender,
the Loan Administrator and the Board has actively engaged in the negotiation of
all of the terms of this Agreement. The Board has met with the Borrower and
Holdings to discuss the business, affairs, financial condition and prospects of
the Borrower. The Agent has no duty or responsibility, either initially or on a
continuing basis, to provide any Lender, the Loan Administrator or the Board
with any credit or other information with respect to the Borrower whether coming
into its possession as of the date of this Agreement or at any time thereafter,
or to notify any Lender, the Loan Administrator or the Board of any Event of
Default except as provided in Section 9.5 hereof. This Agreement and all
instruments or documents delivered in connection with this Agreement have been
reviewed and approved by each Lender, the Loan Administrator and the Board and
none of the Lenders, the Loan Administrator nor the Board have relied on the
Agent as to any legal or factual matter in connection therewith or in connection
with the transactions contemplated thereunder.

      SECTION 9.5. EVENTS OF DEFAULT; TERMINATION OF BOARD GUARANTEE.

      (a) In the event of the occurrence of any Default or Event of Default, any
Lender, any Counter-Guarantor or the Board knowing of such event may (but shall
have no duty to), or the Borrower pursuant to Section 5.1(v) hereof shall, give
the Agent written notice specifying such Event of Default or other event and
expressly stating that such notice is a "notice of default". The Agent shall not
be deemed to have knowledge of such events unless the Agent has received such
notice, or unless the Event of Default

                                       77
<PAGE>
consists of a failure of payment of principal or interest on the Note. In the
event that the Agent receives such a notice of the occurrence of an Event of
Default, the Agent shall give written notice thereof to the Lenders, the
Counter-Guarantors, the Loan Administrator and the Board. The Agent shall take
such action with respect to such Default or Event of Default as shall be
reasonably directed in writing by the Board or, if the Board Guarantee is no
longer in full force and effect, the Requisite Lenders, provided, however, that,
unless and until the Agent shall have received such directions, the 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 and of the Board.

      (b) In the event the Agent shall receive any notice from the Board to the
effect that (i) the Board has the right to terminate the Board Guarantee under
Section 2.05 thereof, (ii) any portion of the Board Guarantee has terminated
under Section 2.04 thereof or otherwise, or (iii) the Board Guarantee shall for
any reason have ceased to be in full force and effect or the Board shall have
asserted that any of its obligations thereunder is invalid or unenforceable, the
Agent shall promptly give written notice thereof to the Lenders. The Agent shall
not be deemed to have knowledge of any such event unless the Agent has received
such notice (except if any such event results from the failure of the Agent to
perform any of its obligations under the Board Guarantee).

      SECTION 9.6. AGENT'S RIGHT TO INDEMNITY. Except for action expressly
required of the Agent hereunder without instructions from any Person, the Agent
shall be fully justified in failing or refusing to take any action hereunder on
behalf of any Lender or the Board unless it shall first be indemnified to its
satisfaction by such Lender or the Board, as the case may be, 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 9.7. INDEMNIFICATION OF AGENT. The Lenders hereby agree to
indemnify the Agent and all affiliates, directors, officers, employees, advisors
and representatives thereof (to the extent not reimbursed by the Borrower),
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 Agent in
any way relating to or arising out of this Agreement and/or the Note or any
action taken or omitted by the Agent under this Agreement and/or the Note;
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 Agent's gross negligence or
willful misconduct. Without limitation of the foregoing, each Lender agrees to
reimburse the Agent promptly upon demand for its ratable share of any
out-of-pocket expenses (including counsel fees) incurred by the Agent in
connection with the administration, or enforcement of, or the preservation of
any rights under, this Agreement and/or the Note, to the extent that the Agent
is not reimbursed for such expenses by the Borrower.

                                       78
<PAGE>
      SECTION 9.8. SUCCESSOR AGENT. The Agent may with the consent (not to be
unreasonably withheld), of the Lenders, the Board and the Counter-Guarantors,
resign at any time by giving written notice thereof to the Lenders, the Board,
the Counter-Guarantors and the Borrower and may be removed at any time with
cause (or, following the Board's honoring of a demand for payment in accordance
with the Board Guarantee, without cause) by the Board. Upon any such resignation
or removal, the Borrower shall have the right to appoint a successor Agent,
subject to confirmation by the Board, the Lenders and the Counter-Guarantors. If
no successor Agent shall have accepted such appointment within 30 days after the
retiring Agent's giving of notice of resignation or the Board's removal of the
Agent the Agent may, with the consent (not to be unreasonably withheld) of the
Board, the Lenders and the Counter-Guarantors, appoint a successor Agent who
shall be willing to accept such appointment. In any event such successor Agent
shall be a commercial bank organized under the laws of the United States of
America or of any State thereof and shall have a combined capital and surplus of
at least $1,000,000,000. Upon the acceptance of any appointment as Agent
hereunder by a successor Agent, such successor Agent shall thereupon succeed to
and become vested with all the rights, powers, privileges and duties of the
retiring or removed Agent, and the retiring or removed Agent shall be discharged
from its duties and obligations as agent under this Agreement. After any Agent's
resignation or removal hereunder as Agent 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 Agent under this Agreement.

                                  MISCELLANEOUS

      SECTION 10.1. 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 the
Borrower therefrom shall in any event be effective unless the same shall be in
writing and (i) so long as the Board Guarantee is in full force and effect,
signed by the Board or (ii) if the Board Guarantee is no longer in effect,
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 and each Counter-Guarantor,
do any of the following:

            (i) subject the Lenders or the Counter-Guarantors to any additional
      obligations;

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

                                       79
<PAGE>
            (iii) change the principal amount of the Loan (other than by the
      payment or prepayment thereof);

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

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

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

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

            (viii) amend or modify any material provision of Articles II, III,
      IV, IX, Sections 5.1 (other than 5.1(i)(b)), 5.2, 5.5, 6.1(A)(ii), 6.3,
      6.4, 7.1 (other than to add Events of Default), 10.1, 10.2, 10.3, 10.4,
      10.6, 10.7, 10.10, 10.11, 10.12, 10.13, 10.16 and 10.18 or any of the
      definitions as relevant thereto;

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

      (b) The 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 Borrower in any case shall entitle the Borrower to
any other or further notice or demand in similar or other circumstances.

      (c) Notwithstanding anything herein to the contrary, in the event that the
Borrower shall have requested each of the Lenders and the Counter-Guarantors, in
writing, to agree to an amendment, modification, waiver or consent with respect
to any particular provision or provisions hereof, and any such Lender or
Counter-Guarantor shall have failed to state, in writing, that it either agrees
or disagrees (in full or in part) with such request (in the case of its
statement of agreement, subject to satisfactory documentation and such other
conditions it may specify) within 30 days of such request, then such Lender or
Counter-Guarantor hereby irrevocably authorizes the Agent to agree or disagree,
in full or in part, and in the Agent's sole discretion, to such requests on
behalf of such Lender or Counter-Guarantor as such Lender's or
Counter-Guarantor's attorney-in-fact and to execute and deliver any writing
approved by the Agent which evidences such agreement as such Lender's or
Counter-Guarantor's duly authorized agent for such purposes.

                                       80
<PAGE>
      (d) In connection with any proposed amendment, modification, waiver or
termination (a "Proposed Change") requiring the consent of all affected Lenders,
if the consent of 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 10.1 being referred to as a
"Non-Consenting Lender"), then, so long as the Lender that is acting as the
Agent is not a Non-Consenting Lender, at the Borrower's request, the Agent or an
Eligible Lender that is acceptable to the Agent and the Board shall have the
right with the Agent's consent and in the 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 Agent's request, sell and
assign to the Lender that is acting as the Agent or such Eligible Lender, 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
Acceptance.

      SECTION 10.2. ASSIGNMENTS AND PARTICIPATIONS.

      (a) Each Lender may sell, transfer, negotiate or assign either in whole or
in part to one or more Eligible Lenders its rights and obligations hereunder and
under the Note and the other Loan Documents without the prior consent of the
Borrower but with the consent, not to be unreasonably withheld, of the Agent,
and, except as otherwise provided in Section 10.2(d), the prior written approval
of the Board (such consent, in the case of an assignment to an Affiliate of the
Initial Lender that is an Eligible Lender, not to be unreasonably withheld);
provided, that (i) the assigning Lender shall give prompt written notice to the
Agent and the Board of the terms of and the parties to any such assignment, (ii)
the proposed assignee shall provide to the Agent and the Board all documentation
and certificates as required by the Agent and the Board to confirm to the
Agent's and the Board's satisfaction that such proposed assignee is an Eligible
Lender, and (iii) the Borrower will not be obligated to pay any greater amount
under Section 2.10(c) or Section 2.12(a) (in respect of increased costs or
Indemnified Taxes imposed pursuant to applicable law in effect on the date of
such assignment) to the assignee than the Borrower is then obligated to pay to
the assigning Lender under such Sections; provided, however, that the consent of
the Board shall not be required for any assignment which occurs after payment in
full has been made under the Board Guarantee or the Board Guarantee shall have
terminated.

      (b) The parties to each assignment shall execute and deliver to the Agent,
for its acceptance and recording, an Assignment and Acceptance, and the
assignee, if a Non-U.S. Person, shall deliver to the Borrower, the Agent and
each Counter-Guarantor, on or prior to the date of the assignment, two completed
copies of either IRS Form W-8BEN or W-8ECI or other applicable form, certificate
or document required to satisfy the requirements of Section 2.12. Upon such
execution, delivery and acceptance and the receipt by the Agent of an assignment
fee in the amount of $10,000 (which shall be for the account of the Borrower),
the Agent shall record such Assignment

                                       81
<PAGE>
and Acceptance and from and after the effective date specified in such
Assignment and Acceptance (i) the assignee thereunder of all or any portion of
the Loan shall become a party hereto and, to the extent that rights and
obligations under the Loan Documents have been assigned to such assignee
pursuant to such Assignment and Acceptance, have the rights and obligations of a
Lender and (ii) the assignor thereunder shall, to the extent that rights and
obligations under this Agreement have been assigned by it pursuant to such
Assignment and Acceptance, relinquish its rights (except those which survive the
payment in full of the Obligations) and be released from its obligations under
the Loan Documents, other than those relating to events or circumstances
occurring prior to such assignment (and, in the case of an Assignment and
Acceptance covering all or the remaining portion of an assigning Lender's rights
and obligations under the Loan Documents, such Lender shall cease to be a party
hereto).

      (c) Upon its receipt of an Assignment and Acceptance executed by an
assigning Lender and an assignee, the Agent shall, if such Assignment and
Acceptance has been completed, (i) accept such Assignment and Acceptance, (ii)
record the information contained therein in the Register, (iii) give prompt
notice thereof to the Borrower and (iv) shall give prompt written notice of the
terms of and parties to any such assignment.

      (d) In addition to the other assignment rights provided in this Section
10.2, each Lender may assign, without the prior consent of the Borrower, the
Agent or the Board as collateral or otherwise, any of its rights under this
Agreement to any Federal Reserve Bank pursuant to Regulation A of the Federal
Reserve Board, provided, however, that no such assignment shall release the
assigning Lender from any of its obligations hereunder.

      (e) Each Lender may, without the prior consent of the Borrower or any
other Person, sell participations, to the extent permitted by the Regulations
and except as provided in Section 5.04(b) of the Board Guarantee, in or to all
or a portion of its rights and obligations hereunder and under the Note and the
other Loan Documents (any such purchaser of a participation being referred to as
a "Participant"); provided that (i) neither the Note nor the Board Guarantee is
assigned, conveyed, sold or transferred in whole or in part, (ii) the Board's
ability to assert any and all defenses available to it under the Board Guarantee
and the law is not adversely affected and (iii) the Borrower will not be
obligated to pay any greater amount under Section 2.10(c) or Section 2.12(a) (in
respect of increased costs or Indemnified Taxes imposed pursuant to applicable
law in effect on the date of such participation) to the Participant than the
Borrower is then obligated to pay to any selling Lender under such Sections. In
the event of the sale of any participation by any Lender, (A) such Lender's
obligations under the Loan Documents shall remain unchanged, (B) such Lender
shall remain solely responsible to the other parties for the performance of such
obligations, (C) such Lender shall remain the holder of such Obligations for all
purposes of this Agreement, (D) the Agent, the Board and the other Lenders shall
continue to deal solely and directly with such Lender in connection with such
Lender's rights and obligations under this Agreement, and (E) each Participant,
if a Non-U.S. Person, shall deliver to the Borrower, the Agent and each
Counter-Guarantor,

                                       82
<PAGE>
on or prior to the date of the sale of the participation, two completed copies
of either IRS Form W-8BEN or W-8ECI or other applicable form, certificate or
document required to satisfy the requirements of Section 2.12. Any Participant
will be entitled to the benefits of Sections 2.10(c), 2.10(e), 2.11 and 2.12 to
the same extent as if such Person were a Lender.

      SECTION 10.3. COSTS AND EXPENSES. Whether or not the transactions
contemplated hereby shall be consummated, the Borrower agrees to pay promptly
(i) all costs and expenses incurred by the Loan Administrator, the Initial
Lender, each Counter-Guarantor and the Agent in connection with the negotiation,
preparation, execution and delivery of the Loan Documents, the Servicing
Agreement, each Counter-Guarantee, the Board Guarantee and all documents
relating thereto (including reasonable legal fees and expenses), (ii) all costs
and expenses incurred by the Loan Administrator, the Lenders, the
Counter-Guarantors, any Participant and the Agent in connection with any
consents, amendments, waivers or other modifications hereto or thereto
(including reasonable legal fees and expenses), (iii) all costs and expenses
incurred by the Agent in connection with the syndication of the Loan (if any),
and (iv) all costs and expenses, including reasonable legal fees and expenses
incurred by the Agent, Lenders, the Loan Administrator, each Counter-Guarantor
and any Participant in enforcing any Obligations of, or in collecting any
payments due from, the Borrower hereunder or under the other Loan Documents.

      SECTION 10.4. INDEMNITIES. Whether or not the transactions contemplated
hereby shall be consummated, the Borrower agrees to defend, indemnify, pay and
hold harmless the Board, the Agent, the Lenders, the Loan Administrator, each
Counter-Guarantor and their respective Affiliates, officers, directors,
employees, agents and advisors (collectively called the "Indemnitees") from 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 counsel for such Indemnitees, but excluding Taxes), whether
direct, indirect or consequential and whether based on any federal, state or
foreign laws, statutes, rules or regulations (including without limitation
securities and commercial laws, statutes and rules or regulations), on common
law or equitable cause or on contract or otherwise, that may be imposed on,
incurred by, or asserted against any such Indemnitee, in any manner arising out
of this Agreement, the other Loan Documents, any Counter-Guarantee or the
transactions contemplated hereby or thereby (including, without limitation, the
use or intended use of the proceeds of the Loan) or the syndication of the Loan
or any statement contained in the Application or otherwise made by or on behalf
of the Borrower to the Board or any breach or default by the Borrower of any
provision of the Loan Documents (collectively called the "Indemnified
Liabilities"); provided that the Borrower shall not have any obligation to any
Indemnitee hereunder with respect to any Indemnified Liabilities to the extent
such Indemnified Liabilities arise (i) from the gross negligence or willful
misconduct of that Indemnitee (as actually and finally determined by a final,
non-appealable judgment of a court of competent jurisdiction) and only to the
extent such Indemnified Liabilities constitute direct (as opposed to special,
indirect, consequential or punitive) damages or (ii) constitute ordinary and
usual operating or overhead expenses of an Indemnitee (excluding, without

                                       83
<PAGE>
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 Borrower 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. No Indemnitee shall have any liability (whether direct or indirect, in
contract, tort or otherwise) to the Borrower or any of its security holders or
creditors for or in connection with the transactions contemplated hereby, except
to the extent such liability is determined in a final, non-appealable judgment
by a court of competent jurisdiction to have resulted primarily from such
Indemnitee's gross negligence or willful misconduct. In no event, however, shall
any Indemnitee be liable on any theory of liability for any special, indirect,
consequential or punitive damages (including, without limitation, any loss of
profits, business or anticipated savings).

      SECTION 10.5. 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
Borrower at any time or from time to time, without notice to the Borrower 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 the Borrower against and on
account of the obligations and liabilities of the Borrower to that Lender under
this Agreement, the Note, and the other Loan Documents, including, but not
limited to, all claims of any nature or description arising out of or connected
with this Agreement, the Note, or any other Loan Document, irrespective of
whether or not (i) that Lender shall have made any demand hereunder or (ii) the
principal of or the interest on the Loan or any other amounts due hereunder
shall have become due and payable pursuant to Section 7.2 and although said
obligations and liabilities, or any of them, may be contingent or unmatured.

      SECTION 10.6. 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 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, 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,
then the Lender receiving such proportionately greater payment shall (i) notify
the Agent and

                                       84
<PAGE>
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 Borrower 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 Borrower expressly consents 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 Borrower to that holder with respect thereto as fully as if
that holder were owed the amount of the participation held by that holder.

      SECTION 10.7. 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 of
telefacsimile, or five Business Days after depositing it in the United States
mail with postage prepaid and properly addressed; provided that notices shall
not be effective until received. For the purposes hereof, the address of each
party hereto and each Counter-Guarantor shall be as set forth under such party's
name on Annex A, or (i) as to the Borrower and the Agent, such other address as
shall be designated by such Person in a written notice delivered to the other
parties hereto and (ii) as to each other party hereto, such other address as
shall be designated by such party in a written notice delivered to the Agent.

      SECTION 10.8. NO WAIVER; REMEDIES. No failure on the part of the Board,
any Lender or the 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.

      SECTION 10.9. INDEPENDENCE OF COVENANTS. All covenants under this
Agreement shall be given independent effect so that if a particular action or
condition is not permitted by any of such covenants, the fact that it would be
permitted by an exception to, or would otherwise be within the limitations of,
another covenant shall not avoid the occurrence of an Event of Default or
Default if such action is taken or condition exists.

      SECTION 10.10. GOVERNING LAW. This Agreement and the rights and
obligations of the parties hereto shall be governed by, and construed in
accordance with,

                                       85
<PAGE>
the law of the State of New York; provided, that in the event the Board becomes
a Lender pursuant to the Board Guarantee, the rights and obligations of the
Board hereunder shall be governed by, and construed in accordance with, the
Federal law of the United States of America, if and to the extent such Federal
law is applicable, and otherwise in accordance with the law of the State of New
York.

other Loan Document may be brought in the courts of the State of New York or of
the United States of America for the Southern District of New York, and, by
execution and delivery of this Agreement, the Borrower hereby accepts for itself
and in respect of its property, generally and unconditionally, the jurisdiction
of the aforesaid courts. The parties hereto hereby irrevocably waive any
objection, including any objection to the laying of venue or based on the
grounds of forum non conveniens, which any of them may now or hereafter have to

      (f) The Borrower hereby irrevocably consents to the service of any and all

this Agreement or any of the other Loan Documents by the mailing (by registered
or certified mail, postage prepaid) or delivering of a copy of such process to
the Borrower in accordance with the provisions of Section 10.7. The Borrower
agrees that a final judgment in any such action or proceeding shall be
conclusive and may be enforced in other jurisdictions by suit on the judgment or
in any other manner provided by law.

      (c) Nothing contained in this Section 10.11 shall affect the right of the
Agent or any Lender to serve process in any other manner permitted by law or
commence legal proceedings or otherwise proceed against the Borrower in any
other jurisdiction.

      SECTION 10.12. WAIVER OF JURY TRIAL. The Borrower irrevocably waives trial
by jury in any action or proceeding with respect to this Agreement or any other
Loan Document.

      SECTION 10.13. MARSHALING; PAYMENTS SET ASIDE. Neither the Agent nor any
Lender shall be under any obligation to marshal any assets in favor of the
Borrower or any other party or against or in payment of any or all of the
Obligations. To the extent that the Borrower makes a payment or payments to the
Agent for the account of the Board, the Loan Administrator, any Lender or any
Counter-Guarantor (each, a "Payee") or any Payee receives payment from exercise
of their rights of setoff, and such payment or payments or the proceeds of such
setoff or any part thereof are subsequently invalidated, declared to be
fraudulent or preferential, set aside or required to be repaid to a trustee,
receiver or any other party, then (i) to the extent of such recovery, the
obligation or part thereof originally intended to be satisfied, and all rights
and remedies

                                       86
<PAGE>
therefor, shall be revived and continued in full force and effect as if such
payment had not been made or such enforcement or setoff had not occurred, and
(ii) each Payee shall pay and return such amount to the Agent as the Agent may
be required to disgorge or otherwise pay to a trustee, receiver or any other
party in respect of the portion of the payment from the Borrower distributed by
the Agent to such Payee hereunder.

      SECTION 10.14. SECTION TITLES. The Section titles contained in this
Agreement are and shall be without substantive meaning or content of any kind

      SECTION 10.15. EXECUTION IN COUNTERPARTS. This Agreement may be executed
in any number of counterparts and by different parties in separate counterparts,

      SECTION 10.16. THIRD PARTY BENEFICIARY. Each Counter-Guarantor shall be an
express third party beneficiary of this Agreement to the extent the provisions
of this Agreement by their terms confer upon such Counter-Guarantor any right or
remedy and shall be entitled to rely on each representation and warranty of the
Borrower hereunder as fully and with the same force and effect as if made
expressly to such Counter-Guarantor, and the execution and delivery of its
Counter-Guarantee to the Agent shall constitute such Counter-Guarantor's
agreement to the provisions of Section 10.18 and further agreement to be bound
by the terms and conditions hereof applicable to the Counter-Guarantors
(including, without limitation, Sections 2.8, 2.9, 10.13 and 10.18 hereof) in
asserting any right or remedy hereunder.

      SECTION 10.17. SEVERABILITY. In case any provision in or obligation under
this Agreement or the Note shall be invalid, illegal or unenforceable in any
jurisdiction the validity, legality and enforceability of the remaining
provisions or obligations, or of such provision or obligation in any other

                            ASSIGNMENT AND ACCEPTANCE

                  ASSIGNMENT AND ACCEPTANCE dated as of _________, ____ between
______________ (the "Assignor") and ______________ (the "Assignee").

         Reference is made to the Loan Agreement, dated as of January 18, 2002
(as the same may be amended, restated, supplemented or otherwise modified from
time to time, the "Loan Agreement"), among the Borrower, Citibank, N.A.., as
Initial Lender and as Agent, KPMG Consulting, Inc.. as the Loan Administrator,
and Air Transportation Stabilization Board. Capitalized terms used herein and
not otherwise defined herein are used herein as defined in the Loan Agreement.

         The Assignor and the Assignee hereby agree as follows:

1.       The Assignor hereby sells and assigns to the Assignee, and the Assignee
         hereby purchases and assumes from the Assignor, [all of] [a __%
         interest in] the Assignor's rights and obligations under the Loan
         Agreement and the Note. The principal amount of the portion of the Loan
         and the Note assigned to the Assignee are set forth in Section 1 of
         Schedule I [and the principal amount of the Loan and the Note retained
         by the Assignor after giving effect to such sale and assignment are set
         forth in Section 2 of Schedule I.].

2.       The Assignor (i) represents and warrants that it is the legal and
         beneficial owner of the interest being assigned by it hereunder and
         that such interest is free and clear of any adverse claim; (ii) makes
         no representation or warranty and assumes no responsibility with
         respect to any statements, warranties or representations made in or in
         connection with the Loan Agreement or any other Loan Document or any
         other instrument or document furnished pursuant thereto or the
         execution, legality, validity, enforceability, genuineness, sufficiency
         or value of the Loan Agreement or any other Loan Document or any other
         instrument or document furnished pursuant thereto; and (iii) makes no
         representation or warranty and assumes no responsibility with respect
         to the financial condition of the Borrower or the performance or
         observance by the Borrower of any of its obligations under the Loan
         Agreement or any other Loan Document or any other instrument or
         document furnished pursuant thereto.

3.       The Assignee (i) agrees that it will, independently and without
         reliance upon the Agent, the Assignor or any other Lender and based on
         such documents and information as it shall deem appropriate at the
         time, continue to make its own credit decisions in taking or not taking
         action under the Loan Agreement; (ii) appoints and authorizes the Agent
         to take such action as agent on its behalf and to exercise such powers
         under the Loan Agreement and the other Loan Documents as are delegated
         to the Agent by the terms thereof, together with such powers as are
         reasonably incidental thereto; (iii) agrees that it will perform in
         accordance with their terms all of the obligations which by the terms
         of the Loan Agreement

<PAGE>
         are required to be performed by it as a Lender; (iv) represents and
         warrants that it is an Eligible Lender; (v) confirms it has received
         such documents and information as it has deemed appropriate to make its
         own credit analysis and decision to enter into this Assignment and
         Acceptance; and (vi) specifies as its Lending Office (and address for
         notices) the office set forth beneath its name on the signature pages
         hereof.

4.       Following the execution of this Assignment and Acceptance by the
         Assignor and the Assignee, it will be delivered to the Agent (with a
         copy to the Board) for acceptance and recording by the Agent, together
         with an assignment fee of $10,000. The effective date of this
         Assignment and Acceptance shall be __________ or such later date as of
         which the Board shall have consented to the sale and assignment of [all
         of] [a __% interest in] the Assignor's rights and obligations under the
         Loan Agreement and the Note to the Assignee as provided herein and as
         evidenced by its signed confirmation thereof set forth on the signature
         pages hereof (the "Effective Date").

5.       Upon such acceptance and recording by the Agent, then, as of the
         Effective Date, (i) the Assignee shall be a party to the Loan Agreement
         and, to the extent provided in this Assignment and Acceptance, have the
         rights and obligations under the Loan Agreement of a Lender and (ii)
         the Assignor shall, to the extent provided in this Assignment and
         Acceptance, relinquish its rights (except those which survive the
         payment in full of the Obligations) other than those relating to events
         or circumstances occurring prior to the Effective Date and be released
         from its obligations under the Loan Documents.

6.       Upon such acceptance and recording by the Agent, from and after the
         Effective Date, the Agent shall make all payments under the Loan
         Documents in respect of the interest assigned hereby (i) to or for the
         account of the Assignee, in the case of amounts accrued with respect to
         any period on or after the Effective Date, and (ii) to or for the
         account of the Assignor, in the case of amounts accrued with respect to
         any period prior to the Effective Date.

7.       This Assignment and Acceptance shall be governed by, and be construed
         in accordance with, the law of the State of New York.

8.       This Assignment and Acceptance may be executed in any number of
         counterparts and by different parties on separate counterparts, each of
         which when so executed shall be deemed to be an original and all of
         which taken together shall constitute but one and the same agreement.
         Delivery of an executed counterpart of this Assignment and Acceptance
         by telecopier shall be effective as delivery of a manually executed
         counterpart of this Assignment and Acceptance.

                            SECTION 2. THE GUARANTEE

2.01 The Guarantee. Subject to the terms and conditions set forth
in this Agreement, the Board hereby guarantees, irrevocably and unconditionally
(except to the extent expressly provided in Sections 2.03, 2.04, 2.05 and 2.06),
to the Agent on behalf of the Lender (the "Guarantee") payment of the following
(the sum of all amounts under (a), (b) and (c), the "Guaranteed Amount"):

      (a) eighty-eight and four hundred seventy-three million, one hundred
ninety-three thousand, four hundred seventy-three billionths percent
(88.473193473%) (the "Guaranteed Percentage") of the outstanding and unpaid
principal amount of the Loan not in excess of Three-Hundred and Seventy-Nine
Million Five Hundred and Fifty Thousand U.S. Dollars ($379,550,000) in the
aggregate;

      (b) interest on the principal amount of the Loan specified in (a) above,
accrued at the Guaranteed Interest Rate to and including the scheduled payment
dates thereof; and

      (c) interest on any due and unpaid amounts described in Sections 2.01(a)
and 2.01(b) above, accrued at the Guaranteed Interest Rate from the scheduled
payment dates thereof to but not including the date of actual payment thereof by
the Board.

2.02 Coverage of the Guarantee. Pursuant to Section 107(2) of the Act, the
Guarantee is entitled to the full faith and credit of the United States of
America. The Guarantee constitutes a guarantee of payment and not of collection.
In no event shall the liability of the Board on the Guarantee exceed the
Guaranteed Amount. For the avoidance of doubt, the Guarantee shall not extend to
the repayment of any penalties, fees, indemnified amounts, costs, expenses or
any other amount payable under the Loan Agreement or any Note other than the
Guaranteed Amount.

2.03 Timely Demand. In the event that the Agent, on behalf of the Lender, fails
to make demand on the Board within the time period required in Section 4.02(vi),
the Guarantee of the unpaid installment of principal and/or interest as to which
such timely demand was not made

                                      -4-
<PAGE>
shall automatically terminate with respect thereto. This termination shall be
without prejudice to the right of the Agent, on behalf of the Lender, to make
demand on the Board under this Agreement in respect of any other due and unpaid
installments of principal or interest.

2.04 Prohibited Amendments or Transfers. In the event that the Agent or a
Lender, without the Board's prior written consent, agrees to any material
amendment, written modification or written waiver in violation of Section 5.03
or assigns, conveys, sell or otherwise transfers any interest in or right or
obligation under this Agreement, the Loan Agreement or the Note in violation of
Section 5.04, then the Board shall have the right to terminate the Guarantee
with respect to all or a portion of the Guaranteed Amount by providing written
notice thereof to the Agent, such termination to be effective as of the earlier
of (a) the 30th calendar day after the date on which the Board delivers such
notice to the Agent and (b) any Demand Date unless, prior to such earlier date,
the Agent or such Lender, as the case may be, rescinds or otherwise remedies the
effect of such prohibited action to the satisfaction of the Board, in which case
the Guarantee shall remain in full force and effect.

2.05 No Acceleration. In the event that, without the prior written consent of
the Board (whether given under this Agreement or under the terms of the Loan
Agreement), the Agent shall declare all or any part of the Borrower's
indebtedness under the Loan Agreement to be immediately due and payable or to be
due and payable upon the demand of the Agent (it being understood that
acceleration of the Loan upon an Event of Default under Section 7.1(f) or (g) of
the Loan Agreement is not such a declaration), then the Board shall have the
right to terminate the Guarantee with respect to all or a portion of the
Guaranteed Amount. The Board shall exercise its right to terminate the Guarantee
pursuant to this Section 2.05 by providing written notice thereof to the Agent.
Any termination of the Guarantee by the Board under this Section 2.05 will be
deemed effective as of the date of the relevant declaration by the Agent.

2.06 Guarantee Fee. The Agent, on behalf of Borrower, shall pay to the United
States Department of the Treasury, in accordance with the priorities of payment
specified in the Loan Agreement and to the extent sufficient funds are received
by the Agent from the Borrower for application thereto, the following
(collectively, the "Guarantee Fee"): (a) on the date hereof, the amount of Three
Million Eight Hundred Thousand U.S. Dollars ($3,800,000), and (b) also on the
date hereof and thereafter on each anniversary of the date hereof (or if any
such anniversary date is not a Business Day, then the immediately preceding
Business Day), the amount specified in Schedule I to this Agreement for such
date. Payment of the Guarantee Fee due on the date hereof shall constitute a
condition precedent to the effectiveness of this Agreement. The Agent shall make
each payment pursuant to this Section 2.06 to such account at such bank in New
York City as the Board shall instruct in writing from time to time. Prior to
such payment, the Agent shall hold such funds in trust for the benefit of the
Board, and the Agent hereby irrevocably waives and agrees not to exercise any
banker's lien, right of setoff, right of recoupment, right to combine accounts
or any similar lien, claim or right, it may have now or in the future against or
on such funds, express or implied, statutory or otherwise, to satisfy any
obligation which the Board or any other agency or instrumentality of the Federal
government of the United States of America may owe to the Agent in any capacity.

2.07 Revocation of Borrower's Payment. Notwithstanding the provisions of Section
2.03, the Guarantee shall continue to be binding on the Board with respect to
any payment, or any part

                                      -5-
<PAGE>
thereof, of principal of or interest on any Note that is rescinded or must
otherwise be returned by the Agent or a Lender if such rescission or return of
payment has been compelled by law as the result of the bankruptcy or insolvency
of the Borrower or if such rescission or return of payment is a result of any
law, regulation or decree applicable to the Borrower. A demand on the Board for
payment pursuant to the Guarantee of any such returned amount must be made
promptly but in no event later than thirty (30) days after the Agent or a Lender
has been compelled to return such amount.

                   SECTION 3. REPRESENTATIONS AND WARRANTIES

3.01 Representations and Warranties of the Agent. The Agent represents and
warrants to the Board as follows:

      (a) Bring-down of Representations. All of its certifications set forth in

      (b) Agent Obligations. The Agent has the ability to perform each of its

      (a) Bring-down of Representations. All of its certifications set forth in
writing in the Application were when made or given, and are as of the date

      (b) No Security. The Lender has no security for payment of any of the
Borrower's obligations under the Loan Agreement or the Note, it being expressly
acknowledged and agreed that none of (i) the fees referred to in the Loan
Agreement, (ii) the Counter-Guarantees, or the cash collateral, letters of
credit and guarantees referred to therein or at any time provided thereunder, or
(iii) any guarantee or security given by any affiliate of the Borrower for the
benefit of the Lender, in any such case, constitutes "security" within the
meaning of this Section 3.02(b) or paragraph 3(b) of any Assignment and
Certification delivered to the Board.

                          SECTION 4. CLAIM PROCEDURES

4.01 Failure to Pay. In the event that (i) the Borrower for any reason fails to
pay in full any installment of principal (other than any proposed voluntary
prepayment under Section 2.5(a) of the Loan Agreement) or interest under the
Loan Agreement or any Note for more than thirty (30) calendar days after the due
date of such installment; and (ii) a period of fifteen (15) calendar days has
elapsed since written demand for payment was made by the Agent on the Borrower
(which demand may be omitted only if and to the extent that the making thereof
would be prohibited by any applicable law), then the Agent, on behalf of the
Lender, may make demand on the Board under this Agreement for payment (subject
to Sections 2.03, 2.04 and 2.05) of the Guaranteed Amount.

                                      -6-
<PAGE>
4.02 Demand on the Board. The Agent's demand on the Board must: (i) be in
writing and delivered in accordance with Section 6.02; (ii) be made only by the
Agent; (iii) identify the installment(s) of principal and/or interest unpaid as
of the date of such demand; (iv) include a copy of the Agent's written demand
for payment on the Borrower (or in the event that such demand was omitted with
respect to the Borrower pursuant to Section 4.01, evidence of the applicable
prohibition); (v) include an Assignment and Certification in the form of Annex A
to this Agreement; and (vi) be made, subject to Section 2.07, not later than
sixty (60) calendar days from the due date of the unpaid installment(s) of
principal and/or interest on which the Agent's demand for payment is based.

4.03 Assignment to the Board. On and as of the date on which the Board pays the
Guaranteed Amount in accordance with Section 4.05, the Board shall become
subrogated to, and the Lender shall be deemed to have assigned to the Board,
without recourse and without need of any further action, the Guaranteed
Percentage of the Lender's right, title and interest in and to the principal of
and interest on the Loan and under the Loan Agreement and the Note in respect
thereof and, to such extent, the Board shall have the right to enforce or
participate in any claim (including, without limitation, any claim in
bankruptcy), right or remedy that the Lender then has or may thereafter acquire
against the Borrower under the Loan Agreement or the Note. In addition to the
Assignment and Certification required to be delivered under Section 4.02, the
Agent and the Lender shall, upon request by the Board, execute and deliver such
documents and take such other actions as the Board may reasonably request to
evidence or give effect to such subrogation and assignment, it being understood
and agreed that the execution and delivery of any such document or the taking of
any such action (i) shall not be a condition to the Board's obligation to pay
the Guaranteed Amount in accordance with this Section 4 and (ii) shall be at the
expense of the Board.

4.04 Conditions of Guarantee. The Board hereby waives diligence, presentment,
protest and any requirement that the Agent or the Lender exhaust any right or
take any action against or give notice to the Borrower or the Board, except for
the written demands for payment by the Agent on the Borrower and the Board
required under this Agreement.

4.05 Payment by the Board.

      (a) After the date on which the Agent shall have properly documented its
demand on the Board for payment pursuant to Section 4.02 (the "Demand Date"),
the Board shall, subject to Sections 2.03, 2.04 and 2.05, pay to the Agent,
within forty-five (45) Business Days after the Demand Date, for the benefit of
the Lender, the Guaranteed Amount in a single payment calculated as of the date
of actual payment thereof by the Board.

      (b) Payment of the Guaranteed Amount due under this Agreement shall be
made by the Board to the Agent, for the benefit of the Lender, and such payment
to the Agent shall discharge fully and completely the Board's liability under
this Agreement. After the Demand Date, any funds received by the Agent or the
Board from or on behalf of the Borrower in respect of any of the Borrower's
obligations under the Loan Agreement shall be applied in accordance with the
terms of the Loan Agreement.

                                      -7-
<PAGE>
      (c) If the Guarantee terminates pursuant to Section 2.03, 2.04 or 2.05
with respect to one or more installments of principal and/or interest, all
installments of principal and/or interest as to which the Guarantee has
terminated shall be deemed to have been paid in full when and as due for the
purposes of determining the amount payable by the Board under this Section 4.05.

4.06 Board Payment Does Not Discharge Borrower. Any statute or judicial decision
to the contrary notwithstanding, no payment by the Board to the Agent on behalf
of the Lender under this Agreement shall reduce, discharge, satisfy or terminate
any obligation of Borrower under the Loan Agreement or any Note.

SECTION 5. UNDERTAKINGS OF THE AGENT

      The Agent agrees that so long as the Board remains liable under this
Agreement:

5.01  Notices.

      (a) The Agent shall notify the Board promptly but in no event later than
seven (7) Business Days after the occurrence of an Event of Default arising by
reason of a failure by the Borrower to make any scheduled payment of principal
of or interest on the Loan when due in accordance with the terms of the Loan
Agreement.

      (b) The Agent shall notify the Board promptly but in no event later than
thirty (30) calendar days after (i) receipt of a notice of any other Event of
Default under and in accordance with the provisions of Section 9.5 of the Loan
Agreement, (ii) receipt of any prepayment of the Loan made by or on behalf of
the Borrower under Section 2.5 or 2.6 of the Loan Agreement, and (iii) the
return by the Agent of any payment previously made by the Borrower to the Agent
or the Agent's receipt of any notice from a Lender of such Lender's return of
any payment previously made by the Borrower, in either case, under the
circumstances described in Section 2.07.

5.02 Register. The Agent shall establish and maintain a register for recording
with respect to the Loan (i) the date and amount of each payment on the Loan
made by or on behalf of, or collected from, the Borrower, (ii) the amount of
each such payment applied in accordance with the terms of the Loan Agreement to
scheduled principal of or interest on the Loan and to each of the fees
identified in clauses (d) through (h) of Section 2.8 of the Loan Agreement, and
(iii) the date and amount of each payment made by the Board hereunder. At any
time upon request by the Board delivered in accordance with Section 6.02, the
Agent shall make such register (or a copy thereof certified by the Agent as
true, complete and correct copy) available to the Board.

5.03 Prohibited Amendments. Neither the Agent nor the Lender shall, without the
prior written consent of the Board (whether given by the Board under this
Agreement or the Loan Agreement), agree to any material amendment, written
modification or written waiver of the terms of the Loan Agreement or the Note.

5.04  Prohibited Transfers.

      (a) The Agent shall not, without the Board's prior written consent, assign
or otherwise transfer any of its rights, duties or responsibilities as Agent
under this Agreement, except that the foregoing shall not restrict an assignment
or transfer by operation of law.

                                      -8-
<PAGE>
      (b) The Lender shall not assign, convey, sell or otherwise transfer any of
its rights, interest or obligations under this Agreement, the Loan Agreement or
the Note without the prior written consent of the Board (such consent, in the
case of an assignment to an affiliate of Citibank, N.A. that is a "lender" (as
defined in the Act), not to be unreasonably withheld); provided, however, that
nothing in this Agreement shall prohibit (i) the Lender from pledging and/or
assigning its rights, interests or obligations under the Loan Agreement, the
Note and this Agreement to any Federal Reserve Bank and, in such instances, the
Federal Reserve Bank, as pledgee or assignee, shall have all such rights and
interests, including in the Guarantee, or (ii) the making and performance of the
Counter-Guarantees and the provision of the cash collateral, letters of credit
and guarantees referred to therein or at any time provided thereunder. Nothing
in this Agreement shall be construed as limiting the Lender's rights under the
provisions of Section 1300.23 of the Regulations; provided, however, that
Citibank, N.A., as the initial Lender shall maintain and shall not sell any
participation in that portion of the Loan which is not guaranteed either under
this Agreement or any Counter-Guarantee.

5.05 Indemnification. In the event that (i) the Agent fails to perform any of
its obligations under this Agreement (which failure shall not, except as
provided in Section 2.03, 2.04 or 2.05, limit or otherwise affect the
obligations of the Board under Section 2) or fails to perform any of its
material obligations or covenants to the Board under the Loan Agreement, or (ii)
any representation of the Agent or the Lender set forth in Section 3 or any
certification of the Agent or the Lender set forth in the Application proves to
have been incorrect in any material respect when made, then the Agent or Lender,
as the case may be, shall be liable to the Board for all actual damages suffered
and costs incurred by the Board as the result thereof, and shall indemnify the
Board for such damages and costs (including, without limitation, counsel fees
and expenses incurred by the Board in enforcing its rights under this Section
5.05). Neither the Agent nor the Lender shall, however, be liable for any
incidental or consequential damages. The Board may enforce its rights hereunder,
and pursue all remedies available with respect thereto, in any court of
competent jurisdiction. Anything to the contrary contained herein
notwithstanding, the obligation of the Agent and the Lender to indemnify the
Board shall survive the termination of this Agreement and the payment of all or
any portion of the Guaranteed Amount.

5.06 Multiple Lenders. In the event The Board shall at any time or from time to
time consent to an assignment of a portion of the Loan by the Lender, each
representation, warranty, certification, covenant or other obligation of the
"Lender" in this Agreement thereafter made or given shall be deemed a several
representation, warranty, certification, or covenant or other obligation of each
Lender such that no Lender shall be liable for the acts or omissions of any
other Lender, and the obligation of the Board to any Lender shall not be
affected by the acts or omissions of any other Lender.

                            SECTION 6. MISCELLANEOUS

6.01 Governing Law. THIS AGREEMENT SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE FEDERAL LAW OF THE UNITED STATES OF AMERICA IF AND TO THE

                       AMOUNTS AND TERMS OF THE TERM LOAN

2.1      THE TERM LOAN; NOTES; REGISTER.

         A. THE TERM LOAN. Subject to the terms and conditions of this Agreement
and in reliance upon the representations and warranties of the Company herein
set forth, each Lender hereby agrees to maintain the Loans all as described in
this subsection 2.1A. Each Lender's Loan shall be deemed to have been advanced
under the Existing Credit Agreement, and the principal amount owed to each
Lender on the Closing Date under the Existing Credit Agreement shall be the
principal amount of the Loan owed to such Lender, which such amount is set forth
on Schedule 2.4 hereto. Amounts repaid or prepaid under this Agreement may not
be reborrowed.

         B. NOTES. On the Closing Date, the Company shall execute and deliver to
each Lender (or to the Agent on behalf of each Lender) Notes substantially in
the form of Exhibit III and Exhibit III-A annexed hereto to evidence that
Lender's Loans in the principal amount of the Loans attributable to such Lender
outstanding under the Existing Credit Agreement and with other appropriate
insertions and the Company's Obligations under the PIK Notes.

         C. THE REGISTER.

                  (i) The Agent shall maintain, at its address referred to in
         subsection 9.8, a register for the registration of the names and
         addresses of the Lenders and Loans and PIK Notes of each Lender from
         time to time (the "REGISTER"). The Register shall be available for
         inspection by the Company or any Lender at any reasonable time and from
         time to time upon reasonable prior notice.

                  (ii) The Agent shall record in the Register the Loans from
         time to time of each Lender and each repayment or prepayment in respect
         of the principal amount of the Loans and the PIK Notes. Any such
         recordation shall be conclusive and binding on the Company and each
         Lender, absent manifest error; provided that failure to make any such
         recordation, or any error in such recordation, shall not affect the
         Company's Obligations in respect of the applicable Loans and PIK Notes.

                  (iii) Each Lender shall record on its internal records
         (including, without limitation the applicable Notes held by such
         Lender) the amount of the Loans made by it, PIK Notes held by it and
         each payment or other reduction in respect thereof. Any such
         recordation shall be conclusive and binding on the Company, absent
         manifest error; provided that failure to make any such recordation, or
         any error in such recordation, shall not affect the Company's
         Obligations in respect of the applicable Loans and PIK Notes; and
         provided, further, that in the event of any inconsistency between the
         Register and any Lender's records, the recordations in the Register
         shall govern.

                  (iv) The Company, the Agent and the Lenders shall deem and
         treat the Persons listed as Lenders and holders of the PIK Notes in the
         Register as the holders and owners of the corresponding Loans and PIK
         Notes listed therein for all purposes hereof, and no

                                      -25-
<PAGE>
         assignment or transfer of any such Loans or PIK Notes shall be
         effective, in each case unless and until an Assignment Agreement
         effecting the assignment or transfer thereof shall have been accepted
         by the Agent and recorded in the Register as provided in subsection
         9.1B(ii). Prior to such recordation, all amounts owed with respect to
         the applicable Loans and PIK Notes shall be owed to the Lender and
         holders of PIK Notes listed in the Register as the owner thereof, and
         any request, authority or consent of any Person who, at the time of
         making such request or giving such authority or consent, is listed in
         the Register as a Lender or holder of a PIK Note shall be conclusive
         and binding on any subsequent holder, assignee or transferee of the
         corresponding Loans and PIK Notes.

2.2      INTEREST ON THE LOANS.

         A. RATE OF INTEREST. Subject to the provisions of subsections 2.6 and
2.7, the Loans shall bear interest on the unpaid principal amount thereof from
the date made through maturity (whether by acceleration or otherwise) at a rate
determined by reference to the Base Rate or the Adjusted Eurodollar Rate, as the
case may be. The applicable basis for determining the rate of interest with
respect to the Loans shall be selected by the Company; provided, however, that
initially as of the Closing Date all of the Loans shall be Eurodollar Rate
Loans. The basis for determining the interest rate with respect to the Loans may
be changed from time to time pursuant to subsection 2.2D. If on any day a Loan
is outstanding with respect to which notice has not been delivered to the Agent
in accordance with the terms of this Agreement specifying the applicable basis
for determining the rate of interest, then for that day that Loan shall bear
interest determined by reference to the Base Rate.

         Subject to the provisions of subsection 2.2E and 2.7, the Loans shall
bear interest through maturity as follows:

                  (i) if a Base Rate Loan, then at a rate per annum equal to the
         sum of the Base Rate plus the Applicable Margin; or

                  (ii) if a Eurodollar Rate Loan, then at a rate per annum equal
         to the sum of the Adjusted Eurodollar Rate plus the Applicable Margin.

         B. INTEREST PERIODS. In connection with each Eurodollar Rate Loan, the
interest period (the "INTEREST PERIOD") to be applicable to such Loan, shall be
a one-month period; provided that:

                  (i) each Interest Period shall commence on the day on which
         the next preceding Interest Period expires, or on the date specified in
         the applicable Notice of Conversion/Continuation, in the case of a Loan
         converted to a Eurodollar Rate Loan, provided that the initial Interest
         Period shall commence on the Closing Date, and the Company shall pay
         any breakage amounts pursuant to Section 2.6D in connection with the
         termination of any Interest Period under the Existing Credit Agreement;

                                      -26-
<PAGE>
                  (ii) if an Interest Period would otherwise expire on a day
         that is not a Business Day, such Interest Period shall expire on the
         next succeeding Business Day; provided that, if any Interest Period
         would otherwise expire on a day that is not a Business Day but is a day
         of the month after which no further Business Day occurs in such month,
         such Interest Period shall expire on the next preceding Business Day;

                  (iii) any Interest Period that begins on the last Business Day
         of a calendar month (or on a day for which there is no numerically
         corresponding day in the calendar month at the end of such Interest
         Period) shall, subject to clause (iv) of this subsection 2.2B, end on
         the last Business Day of a calendar month; and

                  (iv) no Interest Period shall extend beyond the scheduled
         Termination Date.

         C. INTEREST PAYMENTS. Subject to the provisions of subsection 2.2E,
interest on each Loan shall be payable in arrears on and to, but not including,
each Interest Payment Date applicable to that Loan, upon any prepayment of that
Loan (to the extent accrued on the amount being prepaid) and at maturity
(including final maturity).

         D. CONVERSION OR CONTINUATION. Subject to the provisions of subsection
2.6, the Company shall have the option (i) to convert at any time all (but not
less than all) of the outstanding Loans from Loans bearing interest at a rate
determined by reference to one basis to Loans bearing interest at a rate
determined by reference to an alternative basis or (ii) upon the expiration of
any Interest Period applicable to a Eurodollar Rate Loan, to continue all (but
not less than all) of the Loans as a Eurodollar Rate Loan. A Eurodollar Rate
Loan converted into a Base Rate Loan on any day other than the last day of an
Interest Period applicable thereto shall be subject to breakage fees in
accordance with Section 2.6D.

         The Company shall deliver a Notice of Conversion/Continuation to the
Agent no later than 12:00 noon (New York time) on the proposed conversion date
(in the case of a conversion to a Base Rate Loan) and at least three Business
Days in advance of the proposed conversion/continuation date (in the case of a
conversion to, or a continuation of, a Eurodollar Rate Loan). A Notice of
Conversion/Continuation shall specify (i) the proposed conversion/continuation
date (which shall be a Business Day), (ii) the amount and type of the Loan to be
converted/continued, (iii) the nature of the proposed conversion/continuation,
and (iv) in the case of a conversion to, or a continuation of, a Eurodollar Rate
Loan, that no Potential Event of Default or Event of Default has occurred and is
continuing.

         Neither the Agent nor any Lender shall incur any liability to the
Company in acting upon any notice referred to above that the Agent believes in
good faith to have been given by a duly authorized officer or other person
authorized to act on behalf of the Company or for otherwise acting in good faith
under this subsection 2.2D, and upon conversion or continuation of the
applicable basis for determining the interest rate with respect to any Loans in
accordance with this Agreement pursuant to any such notice the Company shall
have effected a conversion or continuation, as the case may be, hereunder.

                                      -27-
<PAGE>
         Except as otherwise provided in subsections 2.6B, 2.6C and 2.6G, a
Notice of Conversion/Continuation for conversion to, or continuation of, a
Eurodollar Rate Loan shall be irrevocable on and after the related Interest Rate
Determination Date, and the Company shall be bound to effect a conversion or
continuation in accordance therewith.

         E. DEFAULT RATE. Any amounts not paid when due hereunder or under any
other Loan Document, including, but not limited to, outstanding principal of a
Loan or under a PIK Note and, to the extent permitted by applicable law, any
interest payments thereon and any fees and other amounts, shall thereafter bear
interest payable upon demand from the date when due until the date of payment at
a rate which is 2% per annum in excess of the interest rate otherwise payable
under this Agreement with respect to the applicable Loans or PIK Notes (or, in
the case of any such fees and other amounts, at a rate which is 2% per annum in
excess of the interest rate otherwise payable under this Agreement for Base Rate
Loans); provided that, in the case of Eurodollar Rate Loans, upon the expiration
of the Interest Period in effect at the time any such increase in interest rate
is effective such Eurodollar Rate Loans shall thereupon become Base Rate Loans
and shall thereafter bear interest payable upon demand at a rate which is 2% per
annum in excess of the interest rate otherwise payable under this Agreement for
Base Rate Loans. Payment or acceptance of the increased rates of interest
provided for in this subsection 2.2E is not a permitted alternative to timely
payment and shall not constitute a waiver of any Event of Default or otherwise
prejudice or limit any rights or remedies of the Agent or any Lender.

         F. COMPUTATION OF INTEREST. Interest on each Loan shall be computed on
the basis of a 360-day year, in each case for the actual number of days elapsed
in the period during which it accrues, unless such Loan is a Base Rate Loan with
a Base Rate based upon the Prime Rate, in which event interest shall be computed
on the basis of a year of 365 or 366 days, as the case may be, for the actual
number of days elapsed in the period during which it accrues. In computing
interest on any Loan, the date of the making of such Loan or the first day of an
Interest Period applicable to such Loan or, with respect to a Base Rate Loan
being converted from a Eurodollar Rate Loan, the date of conversion of such
Eurodollar Rate Loan to such Base Rate Loan, as the case may be, shall be
included, and the date of payment of such Loan or the expiration date of an
Interest Period applicable to such Loan or, with respect to a Base Rate Loan
being converted to a Eurodollar Rate Loan, the date of conversion of such Base
Rate Loan to such Eurodollar Rate Loan, as the case may be, shall be excluded
provided that if a Loan is repaid on the same day on which it is made, one day's
interest shall be paid on that Loan.

         G. PAYMENT IN KIND NOTES

         In addition to any other interest payable in respect of the Loans, the
Company shall pay interest in kind on the aggregate outstanding principal amount
of the Loans at a rate of two percent per annum (2%) from the Closing Date
through December 31, 2004. The payment of interest in kind shall be made by the
Company by executing and delivering PIK Notes to each Lender (or to the Agent on
behalf of the Lenders) on the Closing Date. The principal amount of each PIK
Note shall be set forth on the schedule thereto, which schedule shall be
conclusive absent manifest error. The Company shall pay interest in kind on the
PIK Notes on each Interest Payment Date at a rate equal to two percent per annum
(2%), which interest shall be compounded

                                      -28-
<PAGE>
monthly and incorporated into the schedule to each PIK Note and shall be
conclusive absent manifest error.

         On December 31, 2004, the Company shall pay the outstanding principal
amount of the PIK Notes in the amount set forth on the schedule to each PIK
Note; provided, that, so long as no Potential Event of Default or Event of
Default shall then have occurred and be continuing, the Company may elect to add
up to the entire principal amount of each Lender's PIK Note as of December 31,
2004 (as shown on the schedule to such PIK Note) to the principal amount of such
Lender's Loan and the Company shall issue a new Term Note to such Lender
reflecting such additional principal.

2.3      FEES.

         The Company and the Agent shall enter into one or more letter
agreements establishing administrative fees payable by the Company to the Agent
for its administrative services hereunder which fees shall be for the account of
the Agent and not the Lenders.

2.4      PREPAYMENTS; GENERAL PROVISIONS REGARDING PAYMENTS

         A. REPAYMENT OF PRINCIPAL AMOUNT OF LOANS. On each Principal Payment
Date, the Company shall pay to the Agent for the account of the Lenders the
principal amount of thirty million Dollars ($30,000,000), or, in the case of the
Termination Date, the aggregate outstanding principal amount of all Loans,
together on each such date with all accrued and unpaid interest thereon and all
fees and other amounts payable by the Company under this Agreement; provided,
that the payment on the Termination Date shall be in amount sufficient to repay
in full the PIK Notes and all other Obligations of the Company (other than those
Obligations which are contingent Obligations not then due and payable, such as
contingent indemnities).

B.       PREPAYMENTS.

         (i) Voluntary Prepayments. The Company may, with respect to Eurodollar
Rate Loans, upon not less than three Business Days' prior written notice given
to the Agent by 12:00 noon (New York time) on the date so required and, with
respect to Base Rate Loans and the PIK Notes, upon prior written notice given to
the Agent by 12:00 noon (New York time) on the date of prepayment, at any time
and from time to time prepay, without premium or penalty (other than pursuant to
subsection 2.6D, if applicable), any Loans and PIK Notes on any Business Day in
whole or in part in an aggregate minimum amount of $3,000,000 and integral
multiples of $100,000 in excess of that amount; provided, however, that a
Eurodollar Rate Loan may only be prepaid prior to the expiration date of the
Interest Period applicable thereto upon compliance with subsection 2.6D. Notice
of prepayment having been given as aforesaid, the principal amount of the Loans
and/or PIK Notes specified in such notice shall become due and payable on the
prepayment date specified therein. Any such voluntary prepayment shall be
applied as specified in subsection 2.4B(iii).

         (ii) Mandatory Prepayments and Mandatory Reductions of Loans.

                                      -29-
<PAGE>
(1)      Prepayments Due to Reductions in Borrowing Base.

(a) If at any time there exists a Borrowing Base Deficiency, the Company shall
prepay, without premium or penalty (other than pursuant to subsection 2.6D),
amounts outstanding under the Loans in a principal amount sufficient to
eliminate the Borrowing Base Deficiency, together with accrued and unpaid
interest thereon, provided, that, if no Potential Event of Default (other than a
Potential Event of Default due to such Borrowing Base Deficiency) or Event of
Default shall have then occurred and be continuing, pursuant to subsection
2.10B(ii)(2) the Company may pledge Eligible Assets having an aggregate
appraised Fair Market Value sufficient to eliminate the Borrowing Base
Deficiency. Such prepayment (and collateral arrangements, if any) shall be made
not later than three (3) Business Days following the delivery of (x) a regularly
scheduled Borrowing Base Certificate delivered pursuant to subsection 2.10D
showing a Borrowing Base Deficiency or (y) an updated Borrowing Base Certificate
delivered pursuant to subsection 2.4B(ii)(1)(b), 2.4B(ii)(1)(c) or 7.11 showing
a Borrowing Base Deficiency.

(b) In addition to any notice required by subsection 5.1(xii), if an event
occurs that could reasonably be expected to cause loss of or substantial damage
to Borrowing Base Collateral (excluding Rotables), the Company shall deliver to
the Agent a written notice within three (3) Business Days after a Responsible
Officer of the Company obtains actual knowledge of such event. Such notice shall
identify the specific item(s) of such Borrowing Base Collateral subject to such
event of loss or damage, describe the nature of the event of loss or damage and
include an estimate of whether such loss or damage can reasonably be expected to
exceed $1,000,000. As soon as it can reasonably determine whether such event is
an Event of Loss, Event of Damage or Repairable Damage with respect to the
affected Borrowing Base Collateral but in any event not later than 30 days after
the Company's notice with respect to such event, the Company shall deliver to
the Agent an updated Borrowing Base Certificate in which the Company shall
certify that such event is either an Event of Loss, Event of Damage or
Repairable Damage, with respect to the item(s) of affected Borrowing Base
Collateral. If the Company fails to deliver such updated Borrowing Base
Certificate by such date, it shall be deemed to have delivered an updated
Borrowing Base Certificate as provided in this subsection 2.4B(ii)(1)(b)
certifying that such event is an Event of Loss of the affected Borrowing Base
Collateral. Such updated Borrowing Base Certificate shall exclude from the
Borrowing Base any such Borrowing Base Collateral subject to an Event of Loss,
Event of Damage or Repairable Damage, provided, however, that (1) any such
Borrowing Base Collateral other than the Maintenance Facility that has suffered
Repairable Damage shall not be excluded if (A) such Repairable Damage is covered
by insurance which will pay proceeds in at least the amount of the repair costs
(net of any permitted self-insurance and deductibles) and the Agent is the loss
payee of such insurance pursuant to the terms of the relevant Security
Agreement, each as certified by the Company in the updated Borrowing Base
Certificate and (B) the Company elects to repair such Borrowing Base Collateral
as certified in the updated Borrowing Base Certificate and (2) Borrowing Base
Collateral comprising the Maintenance Facility that has suffered Repairable
Damage shall not be excluded and the Borrower shall repair the Maintenance
Facility unless (A) the cost of such repair is likely to exceed $1,000,000 as
reasonably estimated by the Company, as certified by the Company in such updated
Borrowing Base Certificate, or by the Agent (following consultation, in the case
of the Agent, with an Approved Appraiser) by notice delivered by the Agent to
the Company and (B) the Repairable Damage is not covered by insurance which will
pay proceeds to

                                      -30-
<PAGE>
the Agent, as loss payee, in at least the amount of the repair costs (net of any
permitted self-insurance and deductibles), as certified by the Company in such
updated Borrowing Base Certificate. If such updated Borrowing Base Certificate
shows a Borrowing Base Deficiency, the Company shall make a prepayment (and/or
provide collateral) as provided in subsection 2.4B(ii)(1)(a).

(c) If an event occurs that could reasonably be expected to cause an Adjustment
Event (as reasonably determined by the Company), the Company shall deliver to
the Agent a written notice within three (3) Business Days after a Responsible
Officer of the Company obtains actual knowledge of such event. Such notice shall
identify the location and type (to the extent reasonably possible) of the
affected Rotables, describe the event of loss or damage and include an estimate
of whether such loss or damage can reasonably be expected to exceed $1,000,000.
As soon as it can reasonably determine whether such event is an Adjustment Event
but in any event not later than 30 days after the Company's notice of such
event, the Company shall deliver to the Agent an updated Borrowing Base
Certificate in which the Company shall certify whether or not such event is an
Adjustment Event. If the Company fails to deliver such updated Borrowing Base
Certificate by such date, it shall be deemed to have delivered an updated
Borrowing Base Certificate certifying that such event is an Adjustment Event of
the affected Rotables. If such updated Borrowing Base Certificate certifies that
an Adjustment Event has occurred, it shall exclude from the Borrowing Base the
book value of the Rotables subject to the Adjustment Event and shall specify the
amount of such book value excluded for purposes of calculating the Borrowing
Base Value of the Rotables. If such updated Borrowing Base Certificate certifies
that an Adjustment Event has not occurred, it shall make an appropriate
adjustment in the book value of the affected Rotables, as certified in such
Borrowing Base Certificate, to take into account the loss or damage to the
affected Rotables and shall specify the amount of such adjustment for purposes
of calculating the Borrowing Base Value of the Rotables. (For the avoidance of
doubt, the Company shall make or not make adjustments to the book value of
Rotables subject to events of loss or damage not covered by this subsection
2.4B(ii)(1)(c) in accordance with its normal accounting procedures as applied
without regard to the procedures established in this subsection). If such
updated Borrowing Base Certificate shows a Borrowing Base Deficiency, the
Company shall make a prepayment (and/or provide collateral) as provided in
subsection 2.4B(ii)(1)(a).

(d) If the Company elects to repair any Borrowing Base Collateral (other than
the Maintenance Facility) subject to Repairable Damage and so certifies in any
Borrowing Base Certificate or, in the case of the Maintenance Facility only, is
required to repair Repairable Damage to the Maintenance Facility, the Company
shall complete such repair as soon as reasonably practicable.

(e) In any Borrowing Base Certificate delivered as provided in Subsection
2.4B(ii)(1)(b) which requires the exclusion of any Borrowing Base Collateral
pursuant to the terms of such Subsection, the Company may also request the
release of the Lien of the Security Agreement to which such Borrowing Base
Collateral is subject and, provided that no Potential Event of Default or Event
of Default then exists, as certified by the Company in such Borrowing Base
Certificate, and any Borrowing Base Deficiency certified in such Borrowing Base
Certificate is timely paid and additional Collateral (if any) is provided as
required by subsection 2.4B(ii)(1)(a), the Agent shall release such Lien on such
Borrowing Base Collateral simultaneously with the satisfaction of

                                      -31-
<PAGE>
the conditions contained in this subsection 2.4B(ii)(1)(e) and the second
sentence of subsection 2.10B(ii)(1) by executing and delivering such releases as
may be reasonably requested by the Company.

(2) Prepayments Due to Change of Control. Within five Business Days after the
occurrence of a Change of Control, the Company will notify the Agent of such
Change of Control (the giving of such notice not being a prerequisite to the
Agent's giving its notice as provided in this subsection 2.4B(ii)(2)). The Agent
shall, upon receipt of the notice from the Company required by the preceding
sentence, give the Company and the Lenders notice delivered not more than 30
(thirty) days following the occurrence of a Change of Control or, if later, not
more than 30 (thirty) days following delivery of the notice set forth in the
immediately preceding sentence, except as provided in the last sentence of this
subsection 2.4B(ii)(2), that the Company will be required to prepay all
Obligations on a date specified by the Agent in such notice (which shall be not
less than ten (10) days after the date of delivery of such notice). On the date
specified in such notice, except as provided in the last sentence of this
subsection 2.4B(ii)(2), the Company shall pay all outstanding principal and
interest on all Loans and the PIK Notes and all other fees and amounts payable
under any Loan Document. Notwithstanding the foregoing terms of this subsection
2.4B(ii)(2), by notice to the Company and the Agent within five Business Days
after receipt by a Lender of a notice by the Agent as provided in this clause,
such Lender may elect not to have its portion of the Obligations prepaid as
provided in this clause, in which case such portion shall not be prepaid and its
Pro Rata Share shall be adjusted in relationship to the other remaining
outstanding Obligations.

(3) Prepayments Due to Issuances of Indebtedness and Equity. All cash proceeds
received by Holdings or the Company or any of their respective Subsidiaries
(other than The Leisure Company) from any secured or unsecured Indebtedness for
borrowed money (other than purchase money Indebtedness permitted under Section
6.2A(ii)) incurred by Holdings or the Company or any of their respective
Subsidiaries (other than The Leisure Company) or from any Capital Stock (other
than in connection with the exercise of any options, warrants or other rights)
issued by Holdings or the Company or any of their respective Subsidiaries (other
than The Leisure Company), in either case received after the Closing Date (net
of usual and customary underwriting discounts, commissions and other transaction
costs and expenses) shall be paid directly to the Agent for the benefit of the
Lenders, to be applied pursuant to subsection 2.4B(iii), provided, however, that
the Company shall not be obligated to pay such proceeds to the Agent if and to
the extent that (i) the Company is then required pursuant to the Air Carrier
Guarantee Loan Documents to pay such amounts to repay the Government Guaranteed
Loan, or (ii) the Company is prohibited from so repaying the Obligations under
the terms of the Senior Notes and the Company applies such proceeds to repay the
Senior Notes, or (iii) such proceeds of Indebtedness are applied to refinance
assets described in subsection 6.2A(ii) that were acquired by the Company for
cash and not Indebtedness (for the avoidance of doubt, only to the extent of the
Company's cash investment in such assets), or (iv) such proceeds of Indebtedness
relate to the financing of the Company's training facility located in Phoenix,
Arizona existing on the date hereof.

         (iii) Application of Prepayments.

                                      -32-
<PAGE>
(a) Application of Voluntary Prepayments. Any voluntary prepayments pursuant to
subsection 2.4B(i) shall be applied ratably first among the Term Notes until
paid in full and second among the PIK Notes.

(b) Application of Mandatory Prepayments of Loans. Any mandatory prepayments of
the Loans pursuant to subsection 2.4B(ii) shall be applied ratably among the
Lenders according to their Pro Rata Share, in inverse order of maturity, first
to the Term Notes until paid in full and second among the PIK Notes.

         C. GENERAL PROVISIONS REGARDING PAYMENTS.

         (i) Manner and Time of Payment. All payments by the Company of
principal, interest, fees and other Obligations hereunder and under the Notes
shall be made in Dollars in same day funds, without defense, set-off or
counterclaim, free of any restriction or condition, and delivered to the Agent
not later than 2:00 p.m. (New York time) on the date due at the Funding and
Payment Office for the account of Lenders; funds received by the Agent after
that time on such due date shall be deemed to have been paid by the Company on
the next succeeding Business Day.

         (ii) Application of Payments to Principal and Interest. All payments in
respect of the principal amount of any Loan or Note shall include payment of
accrued interest on the principal amount being repaid or prepaid, and all such
payments shall be applied to the payment of interest before application to
principal.

         (iii) Apportionment of Payments. Except as otherwise provided in
subsection 2.4B(ii)(2), aggregate principal and interest payments in respect of
the Loans and Notes shall be apportioned in each case proportionately to each
Lender's respective Pro Rata Share. The Agent shall promptly distribute to each
Lender, at its primary address set forth below its name on the appropriate
signature page hereof or at such other address as such Lender may request, its
Pro Rata Share of all such payments received by the Agent. Notwithstanding the
foregoing provisions of this subsection 2.4C(iii), if, pursuant to the
provisions of subsection 2.6C, any Notice of Conversion/Continuation is
withdrawn as to any Affected Lender or if any Affected Lender makes Base Rate
Loans in lieu of its Pro Rata Share of any Eurodollar Rate Loans, the Agent
shall give effect thereto in apportioning payments received thereafter.

         (iv) Payments on Business Days. Whenever any payment to be made
hereunder shall be stated to be due on a day that is not a Business Day, such
payment shall be made on the next succeeding Business Day and such extension of
time shall be included in the computation of the payment of interest hereunder.

         (v) Notation of Payment. Each Lender agrees that before disposing of
any Note held by it, or any part thereof (other than by granting participations
therein), that Lender will make a notation thereon of the Loan evidenced by that
Note and all principal payments previously made thereon and of the date to which
interest thereon has been paid; provided that the failure to make (or any error
in the making of) a notation made under such Note shall not

                                      -33-
<PAGE>
limit or otherwise affect the Obligations of the Company hereunder or under such
Note with respect to the Loan or any payments of principal or interest on such
Note.

2.5      USE OF PROCEEDS.

         A. GENERAL CORPORATE PURPOSES. The proceeds of the Loan shall be used
by the Company for its general corporate purposes.

         B. MARGIN REGULATIONS. No portion of the proceeds of any borrowing
under this Agreement shall be used by the Company or any of its Subsidiaries in
any manner that might 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 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.

2.6      SPECIAL PROVISIONS GOVERNING EURODOLLAR RATE LOANS.

         Notwithstanding any other provision of this Agreement to the contrary,
the following provisions shall govern with respect to Eurodollar Rate Loans as
to the matters covered:

         A. DETERMINATION OF APPLICABLE INTEREST RATE. As soon as practicable
after 1:00 p.m. (New York time) on each Interest Rate Determination Date, the
Agent shall determine (which determination shall, absent manifest error, be
final, conclusive and binding upon all parties) the interest rate that shall
apply to the Eurodollar Rate Loans for which an interest rate is then being
determined for the applicable Interest Period and shall promptly give notice
thereof (in writing or by telephone confirmed in writing) to the Company and
each Lender.

         B. INABILITY TO DETERMINE APPLICABLE INTEREST RATE. In the event that
the Agent shall have determined (which determination shall be final and
conclusive and binding upon all parties hereto), on any Interest Rate
Determination Date with respect to any Eurodollar Rate Loans, that by reason of
circumstances affecting the interbank Eurodollar market adequate and fair means
do not exist for ascertaining the interest rate applicable to such Loans on the
basis provided for in the definition of Adjusted Eurodollar Rate, the Agent
shall on such date give notice by telefacsimile to the Company and each Lender
of such determination, whereupon (i) no Loans may be converted to, Eurodollar
Rate Loans until such time as the Agent notifies the Company and Lenders that
the circumstances giving rise to such notice no longer exist and (ii) any Notice
of Conversion/Continuation given by the Company with respect to the Loans in
respect of which such determination was made shall be deemed to be rescinded by
the Company.

         C. ILLEGALITY OR IMPRACTICABILITY OF EURODOLLAR RATE LOANS. In the
event that on any date any Lender shall have determined (which determination
shall be final and conclusive and binding upon all parties hereto but shall be
made only after consultation with the Company and the Agent) that the making,
maintaining or continuation of its Eurodollar Rate Loans (i) has become unlawful
as a result of compliance by such Lender in good faith with any law, treaty,
governmental rule, regulation, guideline or order (or would conflict with any
such treaty, governmental rule, regulation, guideline or order enacted, entered
into or

                                      -34-
<PAGE>
promulgated after the date of this Agreement not having the force of law even
though the failure to comply therewith would not be unlawful) or (ii) has become
impracticable, or would cause such Lender material hardship, as a result of
contingencies occurring after the date of this Agreement which materially and
adversely affect the interbank Eurodollar market or the position of such Lender
in that market, then, and in any such event, such Lender shall be an "AFFECTED
LENDER" and it shall on that day give notice (by telefacsimile) to the Company
and the Agent of such determination (which notice the Agent shall promptly
transmit to each other Lender). Thereafter (a) the obligation of the Affected
Lender to convert Loans to Eurodollar Rate Loans shall be suspended until such
notice shall be withdrawn by the Affected Lender, (b) to the extent such
determination by the Affected Lender relates to a Eurodollar Rate Loan then
being requested by the Company pursuant to a Notice of Conversion/Continuation,
the Affected Lender shall convert such Loan to a Base Rate Loan, (c) the
Affected Lender's obligation to maintain its outstanding Eurodollar Rate Loans
(the "AFFECTED LOANS") shall be terminated at the earlier to occur of the
expiration of the Interest Period then in effect with respect to the Affected
Loans or when required by law, and (d) the Affected Loans shall automatically
convert into Base Rate Loans on the date of such termination. Notwithstanding
the foregoing, to the extent a determination by an Affected Lender as described
above relates to a Eurodollar Rate Loan then being requested by the Company
pursuant to a Notice of Conversion/Continuation, the Company shall have the
option, subject to the provisions of subsection 2.6D, to rescind such Notice of
Conversion/Continuation as to all Lenders by giving notice (by telefacsimile) to
the Agent of such rescission on the date on which the Affected Lender gives
notice of its determination as described above (which notice of rescission the
Agent shall promptly transmit to each other Lender). Except as provided in the
immediately preceding sentence, nothing in this subsection 2.6C shall affect the
obligation of any Lender other than an Affected Lender to maintain Loans as, or
to convert Loans to, Eurodollar Rate Loans in accordance with the terms of this
Agreement.

         In the event any Affected Lender shall give a notice to the Company
pursuant to this subsection 2.6C, the Company may give notice to such Lender
(with copies to the Agent) that it wishes to seek one or more Eligible Assignees
to purchase its outstanding Loans, Obligations and Notes. Each Lender giving a
notice to the Company pursuant to this subsection 2.6C agrees to sell its Loans,
Obligations, Notes and interest in this Agreement and the other Loan Documents
pursuant to subsection 9.1B to any such Eligible Assignee for an amount equal to
the sum of the outstanding unpaid principal of and accrued interest on such
Loans, Obligations and Notes plus all other fees and amounts due such Lender
hereunder calculated, in each case, to the date such Loans, Obligations, Notes
and interest are purchased, whereupon such Lender shall have no further rights
or obligations hereunder.

         D. COMPENSATION FOR BREAKAGE OR NON-COMMENCEMENT OF INTEREST PERIODS.
The Company shall compensate each Lender, upon written request by that Lender
(which request shall set forth the basis for requesting such amounts), for all
reasonable losses, expenses and liabilities (including, without limitation, any
interest paid by that Lender to lenders of funds borrowed by it to carry its
Eurodollar Rate Loans and any loss, expense or liability sustained by that
Lender in connection with the liquidation or re-employment of such funds) which
that Lender may sustain: (i) if for any reason (other than a default by that
Lender) a conversion to or continuation of any Eurodollar Rate Loan does not
occur on a date

                                      -35-
<PAGE>
specified therefor in a Notice of Conversion/Continuation, (ii) if any
prepayment or other principal payment or any conversion of any of its Eurodollar
Rate Loans occurs on a date prior to the last day of an Interest Period
applicable to that Loan, (iii) if any prepayment of any of its Eurodollar Rate
Loans is not made on any date specified in a notice of prepayment given by the
Company, or (iv) as a consequence of any other default by the Company in the
repayment of its Eurodollar Rate Loans when required by the terms of this
Agreement.

         E. BOOKING OF EURODOLLAR RATE LOANS. Any Lender may carry or transfer
Eurodollar Rate Loans at, to, or for the account of any of its branch offices or
the office of an Affiliate of that Lender; provided that such action does not
increase the Company's liability under subsection 2.7.

         F. ASSUMPTIONS CONCERNING FUNDING OF EURODOLLAR RATE LOANS. Calculation
of all amounts payable to a Lender under this subsection 2.6 and under
subsection 2.7A shall be made as though that Lender had actually funded each of
its relevant Eurodollar Rate Loans through the purchase of a Eurodollar deposit
bearing interest at the rate obtained pursuant to clause (i) of the definition
of Adjusted Eurodollar Rate in an amount equal to the amount of such Eurodollar
Rate Loan and having a maturity comparable to the relevant Interest Period and
through the transfer of such Eurodollar deposit from an offshore office of that
Lender to a domestic office of that Lender in the United States of America;
provided, however, that each Lender may fund each of its Eurodollar Rate Loans
in any manner it sees fit and the foregoing assumptions shall be utilized only
for the purposes of calculating amounts payable under this subsection 2.6 and
under subsection 2.7A.

         G. EURODOLLAR RATE LOANS AFTER DEFAULT. After the occurrence of and
during the continuation of a Potential Event of Default or an Event of Default,
(i) the Company may not elect to have the Loans be maintained as, or converted
to, a Eurodollar Rate Loan after the expiration of any Interest Period then in
effect for that Loan and (ii) subject to the provisions of subsection 2.6D, any
Notice of Conversion/Continuation given by the Company with respect to a
requested conversion/continuation that has not yet occurred shall be deemed to
be rescinded by the Company.

2.7      INCREASED COSTS; TAXES; CAPITAL ADEQUACY.

         A. COMPENSATION FOR INCREASED COSTS AND TAXES. Subject to the
provisions of subsection 2.7B, in the event that any Lender shall determine
(which determination shall, absent manifest error, be final and conclusive and
binding upon all parties hereto) that any law, treaty or governmental rule,
regulation or order, or any change therein or in the interpretation,
administration or application thereof (including the introduction of any new
law, treaty or governmental rule, regulation or order), or any determination of
a court or governmental authority, in each case that becomes effective after the
date hereof, or compliance by such Lender with any guideline, request or
directive issued or made after the date hereof by any central bank or other
governmental or quasi-governmental authority (whether or not having the force of
law):

         (i) subjects such Lender (or its applicable lending office) to any
additional Tax (other than any Tax on the overall net income of such Lender)
with respect to this

                                      -36-
<PAGE>
Agreement or any of its obligations hereunder or any payments to such Lender (or
its applicable lending office) of principal, interest, fees or any other amount
payable hereunder;

         (ii) imposes, modifies or holds applicable any reserve (including
without limitation any marginal, emergency, supplemental, special or other
reserve), special deposit, compulsory loan, FDIC insurance or similar
requirement against assets held by, or deposits or other liabilities in or for
the account of, or advances or loans by, or other credit extended by, or any
other acquisition of funds by, any office of such Lender (other than any such
reserve or other requirements with respect to Eurodollar Rate Loans that are
reflected in the definition of Adjusted Eurodollar Rate); or

         (iii) imposes any other condition (other than with respect to a Tax
matter) on or affecting such Lender (or its applicable lending office) or its
obligations hereunder or the interbank Eurodollar market;

and the result of any of the foregoing is to increase the cost to such Lender of
maintaining Loans or Notes hereunder or to reduce any amount received or
receivable by such Lender (or its applicable lending office) with respect
thereto; then, in any such case, the Company shall promptly pay to such Lender,
upon receipt of the statement referred to in the next sentence, such additional
amount or amounts (in the form of an increased rate of, or a different method of
calculating, interest or otherwise as such Lender in its sole discretion shall
determine) as may be necessary to compensate such Lender for any such increased
cost or reduction in amounts received or receivable hereunder. Such Lender shall
deliver to the Company (with a copy to the Agent) a written statement, setting
forth in reasonable detail the basis for calculating the additional amounts owed
to such Lender under this subsection 2.7A, which statement shall be conclusive
and binding upon all parties hereto absent manifest error.

         B. WITHHOLDING OF TAXES.

         (i) Payments to Be Free and Clear. All sums payable by the Company
under this Agreement and the other Loan Documents shall be paid free and clear
of and (except to the extent required by law) without any deduction or
withholding on account of any Tax imposed, levied, collected, withheld or
assessed by any governmental authority, domestic or foreign.

         (ii) Grossing-up of Payments. If the Company or any other Person is
required by law to make any deduction or withholding on account of any Tax from
any sum paid or payable by the Company to the Agent or any Lender under any of
the Loan Documents:

                  (a) the Company shall notify the Agent or such Lender of any
         such requirement or any change in any such requirement as soon as the
         Company becomes aware of it;

                  (b) the Company shall remit any such Tax before the date on
         which penalties attach thereto, such remittance to be made (if the
         liability is imposed on the Company) for its own account or (if that
         liability is imposed on the Agent or such Lender, as the case may be)
         on behalf of and in the name of the Agent or such Lender;

                                      -37-
<PAGE>
                  (c) the sum payable by the Company in respect of which the
         relevant deduction, withholding or payment is required shall be
         increased to the extent necessary to ensure that, after the making of
         that deduction, withholding or payment, the Agent or such Lender, as
         the case may be, receives on the due date a net sum equal to what it
         would have received had no such deduction, withholding or payment been
         required or made; and

                  (d) within 30 days after paying any sum from which it is
         required by law to make any deduction or withholding, and within 30
         days after the due date of remittance of any Tax which it is required
         by clause (b) above to remit, the Company shall deliver to the Agent
         evidence satisfactory to the other affected parties of such deduction,
         withholding or payment and of the remittance thereof to the relevant
         taxing or other authority.

(iii)    Evidence of Exemption from U.S. Withholding Tax.

         (a) Each Lender that is organized under the laws of any jurisdiction
other than the United States or any state or other political subdivision thereof
(for purposes of this subsection 2.7B(iii), a "NON-US LENDER") shall deliver to
the Agent for transmission to the Company, on or prior to the Closing Date (in
the case of each Lender listed on the signature pages hereof) or on the date of
the Assignment Agreement pursuant to which it becomes a Lender (in the case of
each other Lender), and at such other times as may be necessary in the
determination of the Company or the Agent (each in the reasonable exercise of
its discretion), two original copies of Internal Revenue Service Form W-8BEN or
W-8ECI (or any successor forms), properly completed and duly executed by such
Lender, or any other form, certificate or statement of exemption required under
the Internal Revenue Code or the regulations issued thereunder to establish that
such Lender is not subject to deduction or withholding of United States federal
income tax with respect to any payments to such Lender of principal, interest,
fees or other amounts payable under any of the Loan Documents.

         (b) Each Lender required to deliver any forms, certificates or other
evidence with respect to United States federal income tax withholding matters
pursuant to subsection 2.7B(iii)(a) hereby agrees that, from time to time after
the initial delivery by such Lender of such forms, certificates or other
evidence, whenever a lapse in time or change in circumstances renders such
forms, certificates or other evidence obsolete or inaccurate in any material
respect, such Lender shall (l) deliver to the Agent for transmission to the
Company two new original copies of Internal Revenue Service Form W-8BEN or
W-8ECI, properly completed and duly executed by such Lender, or any other form,
certificate or statement of exemption required in order to confirm or establish
that such Lender is not subject to deduction or withholding of United States
federal income tax with respect to payments to such Lender under the Loan
Documents or (2) immediately notify the Agent and the Company of its inability
to deliver any such forms, certificates or other evidence.

                                      -38-
<PAGE>
                  (c) The Company shall not be required to pay any additional
         amount to any Non-US lender under clause (c) of subsection 2.7B(ii) if
         such Lender shall have failed to satisfy the requirements of subsection
         2.7B(iii)(a); provided that if such Lender shall have satisfied such
         requirements on the Closing Date (in the case of each Lender listed on
         the signature pages hereof) or on the date of the Assignment Agreement
         pursuant to which it became a Lender (in the case of each other
         Lender), nothing in this subsection 2.7B(iii)(c) shall relieve the
         Company of its obligation to pay any additional amounts pursuant to
         clause (c) of subsection 2.7B(ii) in the event that, as a result of any
         change in any applicable law, treaty or governmental rule, regulation
         or order, or any change in the interpretation, administration or
         application thereof, such Lender is no longer properly entitled to
         deliver forms, certificates or other evidence at a subsequent date
         establishing the fact that such Lender is not subject to withholding as
         described in subsection 2.7B(iii)(a).

         C. CAPITAL ADEQUACY ADJUSTMENT. If any Lender shall have determined
that the adoption, effectiveness, phase-in or applicability after the date
hereof of any law, rule or regulation (or any provision thereof) regarding
capital adequacy, or any change therein or in the interpretation or
administration thereof by any governmental authority, central bank or comparable
agency charged with the interpretation or administration thereof, or compliance
by any Lender (or its applicable lending office) with any guideline, request or
directive regarding capital adequacy (whether or not having the force of law) of
any such governmental authority, central bank or comparable agency, has or would
have the effect of reducing the rate of return on the capital of such Lender or
any corporation controlling such Lender as a consequence of, or with reference
to, such Lender's Loans or Notes or other obligations hereunder to a level below
that which such Lender or such controlling corporation could have achieved but
for such adoption, effectiveness, phase-in, applicability, change or compliance
(taking into consideration the policies of such Lender or such controlling
corporation with regard to capital adequacy), then from time to time, within
five Business Days after receipt by the Company from such Lender of the
statement referred to in the next sentence, the Company shall pay to such Lender
such additional amount or amounts as will compensate such Lender or such
controlling corporation on an after-tax basis for such reduction. Such Lender
shall deliver to the Company (with a copy to the Agent) a written statement,
setting forth in reasonable detail the basis of the calculation of such
additional amounts, which statement shall be conclusive and binding upon all
parties hereto absent manifest error.

         D. SUBSTITUTE LENDERS. In the event the Company is required under the
provisions of this subsection 2.7 to make payments in a material amount to any
Lender, the Company may, so long as no Event of Default or Potential Event of
Default shall have occurred and be continuing, elect to terminate such Lender as
a party to this Agreement; provided that, concurrently with such termination,
(i) the Company shall pay that Lender all principal, interest and fees and other
amounts (including without limitation, amounts, if any, owed under this
subsection 2.7) owed to such Lender through such date of termination, and (ii)
all documents and supporting materials necessary, in the judgment of the Agent
(or if the Agent is also the Lender to be terminated, the successor Agent) to
evidence the termination and/or substitution of such Lender (if applicable)
shall have been received and approved by the Agent as of such date.

                                      -39-

2.8 OBLIGATION OF LENDERS TO MITIGATE.

         Each Lender agrees that, as promptly as practicable after the officer
of such Lender responsible for administering the Loans of such Lender becomes
aware of the occurrence of an event or the existence of a condition that would
cause such Lender to become an Affected Lender or that would entitle such Lender
to receive payments under subsection 2.7, it will, to the extent not
inconsistent with the internal policies of such Lender and any applicable legal
or regulatory restrictions, use reasonable efforts (i) to maintain the Loans of
such Lender or the affected Loans of such Lender through another lending office
of such Lender, or (ii) take such other measures as such Lender may deem
reasonable, if as a result thereof the circumstances which would cause such
Lender to be an Affected Lender would cease to exist or the additional amounts
which would otherwise be required to be paid to such Lender pursuant to
subsection 2.7 would be materially reduced and if, as determined by such Lender
in its sole discretion, the maintaining of such Loans through such other lending
office or in accordance with such other measures, as the case may be, would not
otherwise materially adversely affect such Loans or the interests of such
Lender; provided that such Lender will not be obligated to utilize such other
lending office pursuant to this subsection 2.8 unless the Company agrees to pay
all incremental expenses incurred by such Lender as a result of utilizing such
other lending office as described in clause (i) above. A certificate as to the
amount of any such expenses payable by the Company pursuant to this subsection
2.8 (setting forth in reasonable detail the basis for requesting such amount)
submitted by such Lender to the Company (with a copy to the Agent) shall be
conclusive absent manifest error.

2.9 [INTENTIONALLY OMITTED].

2.10 BORROWING BASE.

         A. BORROWING BASE. The Borrowing Base shall be calculated based upon
the Eligible Assets that from time to time are subject to the Liens of the
Security Agreements and constitute Borrowing Base Collateral. The Borrowing Base
shall exclude any Borrowing Base Collateral that has suffered loss or damage and
is required to be excluded by subsection 2.4B(ii)(1). In addition, if the
portion of the Borrowing Base attributable to the Rotables exceeds thirty five
percent, rounded to the nearest whole percent (35%), of all Borrowing Base as
determined in any calculation of the Borrowing Base contained in a Borrowing
Base Certificate, such excess amount shall be excluded from the calculation of
the Borrowing Base for such period.

B. COLLATERAL.

         (i) Eligible Assets. The Eligible Assets may from time to time include
the property of the types listed on Schedule 2.10 hereto, which schedule shall
include, without limitation, (a) Cash and Permitted Cash Equivalents from time
to time in the Cash Collateral Account, (b) Eligible Stage III Aircraft, (c) the
Maintenance Facility, (d) Eligible Simulators, (e) Eligible Spare Engines and

all such Collateral to be subject to the Liens of Security Agreements on the
Closing Date. Thereafter, subject to subsection 2.10B(ii), the Borrowing Base
Collateral may include the Maintenance Facility, Simulators, Spare Engines,
Rotables and other Eligible Assets which the Company elects from time to time to
make subject to the Liens of Security Agreements, provided, however, that no
Eligible Assets shall be included in the calculation of the Borrowing Base
unless the Lien of a Security Agreement has been perfected in such Collateral
and such Collateral constitutes Borrowing Base Collateral.

         (ii) Release and Addition of Eligible Assets.

                  (1) Release. Except under the circumstances set forth in the
next sentence of this subsection 2.10B(ii)(1), the Agent shall not release the
Liens of the Security Agreements on any Borrowing Base Collateral until payment
in full of all outstanding Loans and all other amounts owed to the Lenders and
the Agent under the Notes and other Loan Documents. Notwithstanding anything in
this subsection 2.10B(ii)(1) to the contrary, the Agent acknowledges that (I)
the Lien of the Spare Parts Security Agreement will be released from the Parts
Collateral in accordance with the terms thereof (including, but not limited to,
the sale in the ordinary course of the Company's business of not more than
$5,000,000 of Parts Collateral in any six month period), and (II) (x) the
Maintenance Facility may be released from the Lien of the Maintenance Facility
Security Agreement if an Event of Loss or an Event of Damage has occurred with
respect to the Maintenance Facility and (y) any Borrowing Base Collateral that
the Company requests to be released pursuant to and in compliance with
subsection 2.4B(ii)(1)(e) may be so released, in each case provided that the
Company complies with the following requirements: (i) the Company shall make any
prepayment and furnish additional collateral (if any) required by subsection
2.4B(ii)(1) if a Borrowing Base Deficiency would result from the reduction in
the Borrowing Base that such release of such Lien would cause as calculated by
the Borrowing Base Certificate delivered pursuant to clause (iv) below, (ii) no
Event of Default or Potential Event of Default has occurred and is continuing,
(iii) the Company has requested such release in writing and certified that it is
entitled to such release under the applicable Security Agreement and this
subsection 2.10 and (iv) the Company shall have delivered an updated Borrowing
Base Certificate giving pro forma effect to such release and certifying that no
Borrowing Base Deficiency will result therefrom (after taking into account any
additional Eligible Assets added to the Borrowing Base Collateral pursuant to,
and in compliance with, subsection 2.10B(ii)(2) concurrently with or prior to
release of such Lien). Following the release of the Lien of a Security Agreement
on any Borrowing Base Collateral pursuant to the terms of this subsection
2.10B(ii)(1), unless and until such Borrowing Base Collateral is again subjected
to the Lien of a Security Agreement, such Borrowing Base Collateral shall no
longer be included in the calculation of the Borrowing Base or in a future
Borrowing Base Certificate.

                  (2) Addition. The Company may from time to time subject
Eligible Assets (other than Rotables) to the Lien of the relevant Security
Agreements upon written notice thereof to the Agent and such additional
Collateral shall be included in the calculation of the Borrowing Base delivered
in an updated Borrowing Base Certificate after (A) except in the case of Cash
and Cash Equivalents in the Cash Collateral Account, an Approved Appraisal has
been delivered to the Agent for such Eligible Assets, (B) the Lien of the
relevant Security Agreement

                                      -41-
<PAGE>
has been perfected in such Eligible Assets, (C) appropriate filings have been
made to protect the Lien and rights of the Agent in any such Eligible Assets as
are deemed necessary by the Agent, (D) the Agent shall have received such
opinions as it shall reasonably request with respect to any such Eligible
Assets, (E) the Agent shall have received insurance certificates and other
documents required by the relevant Security Agreement and all other documents
and actions required by the terms of such Security Agreement shall have been
delivered or shall have occurred to the satisfaction of the Agent, (F) the
Company shall have delivered all other documents and taken all other actions
reasonably requested by the Agent with respect to any such Eligible Assets, (G)
the Agent has satisfied itself that such Eligible Assets are "Aircraft", "Spare
Engines" or "Simulators", as the case may be, within the meaning of this
Agreement and as described in Schedule 2.10 hereof and (H) the Agent shall
notify the Company in writing that it is satisfied that the conditions of this
Section 2.10B(ii)(2) have been satisfied. Rotables shall become subject to the
Lien of the Spare Parts Security Agreement as provided therein, without also
being required to satisfy any of the requirements of this subsection applicable
to Eligible Assets of other types.

                  Expenses. The Company shall pay all expenses of the Agent in
connection with the release and addition of Eligible Assets to the Borrowing
Base and the release or granting and perfection of Liens of Security Agreements
in connection therewith, including, but not limited to, reasonable fees and
expenses of counsel for the Agent, reasonable fees and expenses of special FAA
counsel and filing fees.

         C. APPROVED APPRAISAL AND APPRAISERS.

                  (1) Approved Appraisal. An Approved Appraisal for any
         Borrowing Base Collateral shall mean (A) an appraisal and inspection
         report satisfactory to the Agent delivered to the Agent by an Approved
         Appraiser not later than the time that such Borrowing Base Collateral
         becomes subject to the perfected Lien of a Security Agreement, (B) an
         appraisal and inspection report satisfactory to the Agent delivered
         semi-annually thereafter to the Agent by an Approved Appraiser not
         later than six months after the delivery date of the last delivered
         Approved Appraisal (commencing with the appraisals delivered in
         November, 2001), and in any event by no later than May 20 and November

         Company has notified the Agent that such Borrowing Base Collateral has
         been damaged, and (D) in the case of Rotables only, an appraisal and
         inspection report satisfactory to the Agent delivered to the Agent by
         an Approved Appraiser at the written request of the Company at any

         conducted as part of an Approved Appraisal shall mean an inspection of
         a sample of the Rotables by the Approved Appraiser for the purpose of
         determining the accuracy of the inventory reports maintained by the
         Company for the Rotables. The Approved Appraiser delivering any
         Approved Appraisal shall be selected by the Agent. The Company shall
         pay the fees and expenses of the Approved Appraiser in connection with
         delivery of an Approved Appraisal. Any inspection of Borrowing Base
         Collateral by an Approved Appraiser shall be conducted in compliance

         D. BORROWING BASE CERTIFICATE. On the Closing Date and no later than
the 25th day of each May and November thereafter until payment in full of all
Loans outstanding hereunder and all other amounts payable to the Lenders and the
Agent under the Notes and other Loan Documents, the Company shall deliver a
Borrowing Base Certificate to the Agent relating to the then most recently ended
six-month period; provided, however, that in addition to such regular
certificates, the Company shall also deliver Borrowing Base Certificates when
required, pursuant to subsection 2.4B(ii)(1) or 2.10B(ii)(1). Each Borrowing
Base Certificate shall replace and supersede for all purposes of this Agreement
the Borrowing Base Certificate then most recently delivered, and shall be based

shall (1) state each component of Borrowing Base Collateral then subject to
perfected Liens of the Security Agreements, (2) state the portion of the
Borrowing Base established by each component Borrowing Base Collateral, (3)
state the Borrowing Base by aggregating each of the values stated pursuant to
the preceding clause (2), and (4) state the then outstanding principal amount of
the Loans. The Borrowing Base Certificate shall (A) certify that none of the
Borrowing Base Collateral included in the calculation of the Borrowing Base is
subject to an Event of Loss, Event of Damage, Repairable Event or Adjustment
Event or, if any of such Borrowing Base Collateral is subject to an Event of
Loss, Event of Damage, Repairable Damage or Adjustment Event, such Borrowing
Base Certificate shall contain the relevant exclusions for any such Borrowing
Base Collateral subject to such Event of Loss, Event of Damage, Repairable
Damage or Adjustment Event as required by subsections 2.4B(ii)(1) and 2.10A
hereof, (B) certify that no Borrowing Base Deficiency then exists or, if a
Borrowing Base Deficiency then exists, the amount thereof, and (C) certify that
the portion of the Borrowing Base attributable to Rotables stated in the
Borrowing Base Certificate does not exceed thirty five percent, rounded to the
nearest whole percent (35%), of the aggregate Borrowing Base stated in such
certificate or that, if the portion of the Borrowing Base attributable to the
Rotables does exceed thirty five percent, rounded to the nearest whole percent
(35%), of the aggregate Borrowing Base, the portion of the Borrowing Base
attributable to the Rotables in such certificate for purposes of calculating the
Borrowing Base excludes such excess amount. In determining the book value of
Rotables in any Borrowing Base Certificate, the Company shall use its normal
accounting procedures except to the extent that the timing of such procedures
may be shortened pursuant to subsection 2.4B(ii)(1)(c). The Borrowing Base
Certificate shall be certified to be true and accurate by a Responsible Officer
of the Company. Notwithstanding any Borrowing Base Certificate delivered by the
Company, in the event of any dispute between the Company and the Agent regarding
the then outstanding principal amount of the Loans, the records of the Agent
shall determine such outstanding principal amounts, absent manifest error.

standing in every jurisdiction where its assets are located and wherever
necessary to carry out its business and operations, in each case except where
failure to be so qualified or in good standing or a lack of such corporate power
and authority would not in the reasonable determination of the Company be
expected to impair the ability of the Company to perform its payment or other
material obligations under the Loan Documents. Schedule 4.1 annexed hereto (as
so supplemented) correctly sets forth the ownership interest of the Company and
each of its Subsidiaries in each of the Subsidiaries of the Company identified
therein.

the material impairment of the Company's ability to perform its payment and
other material obligations under the Loan Documents; this sentence is intended
to pertain to substantial economic events such as (1) any actual or imminent
regulatory or judicial order revoking or materially restricting the Company's

the most recent financial statements delivered pursuant to subsection 5.1, in
each case except for assets disposed of since the date of such financial

bureau, agency or instrumentality, domestic or foreign, pending or, to the
knowledge of the Company, threatened against or affecting the Company or any of

individually or in the aggregate, are reasonably likely to materially impair the
ability of the Company to perform its payment or other material obligations
under the Loan Documents, the Lease Indenture or the Air Carrier Guarantee Loan
Documents, or (taken as a whole) the Concessions. Neither the Company nor any of
its Subsidiaries is (i) in violation of any applicable laws that, individually

expected to impair the ability of the Company to perform its payment or other
material obligations under the Loan Documents or (ii) subject to or in default

other governmental department, commission, board, bureau, agency or
instrumentality, domestic or foreign, that, individually or in the aggregate,
could in the reasonable determination of the Company be expected to impair the
ability of the Company to perform its payment or other material obligations
under the Loan Documents.

4.7 PAYMENT OF TAXES.

         Except to the extent permitted by subsection 5.3, all federal income
tax returns and other material tax returns and reports of the Company and its

respective properties, assets, income, businesses and franchises which are due

there are no agreements with respect to Taxes between the Company and any taxing
agency or authority.

4.8 PERFORMANCE OF AGREEMENTS; MATERIALLY ADVERSE AGREEMENTS.

         A. Neither the Company nor any of its Subsidiaries is in default in the
performance, observance or fulfillment of any of the material obligations,
covenants or conditions contained in any of its Contractual Obligations (after
giving effect to the application of the proceeds of the Government Guaranteed
Loan), and no condition exists that, with the giving of notice or the lapse of
time or both, would constitute such a default.

         B. Neither the Company nor any of its Subsidiaries is a party to or is
otherwise subject to any agreements or instruments or any charter or other
internal restrictions which, individually or in the aggregate, could in the
reasonable determination of the Company be expected to impair the ability of the
Company to perform its payment or other material obligations under the Loan
Documents or in connection with the Government Guaranteed Loan or the Lease
Indenture, or (taken as a whole) the Concessions.

4.9 GOVERNMENTAL REGULATION.

         Neither the Company nor any of its Subsidiaries is subject to
regulation under the Public Utility Holding Company Act of 1935, the Federal
Power Act, the Interstate Commerce Act or the Investment Company Act of 1940 or
under any other federal or state statute or regulation which may limit its
ability to incur Indebtedness or which may otherwise render all or any portion
of the Obligations unenforceable.

4.10 SECURITIES ACTIVITIES.

         Neither the Company nor any of its Subsidiaries owns or is engaged
principally, or as one of its important activities, in the business of extending
credit for the purpose of purchasing or carrying any Margin Stock, nor shall any

credit to any Person for the purpose of purchasing or carrying any

                                      -52-
<PAGE>
Margin Stock in a manner that violates or causes a violation of Regulations T, U
or X of the Board of Governors of the Federal Reserve System or any other
regulation of such Board.

4.11 EMPLOYEE BENEFIT PLANS.

         Each Plan maintained by the Company or an ERISA Affiliate is in
compliance in all material respects with all applicable laws. Except in such
instances where an omission or failure would in the reasonable determination of
the Company impair the ability of the Company to perform its payment or other
material obligations under the Loan Documents (a) all returns, reports and
notices required to be filed with any regulatory agency with respect to any Plan
have been filed timely and (b) neither the Company nor any ERISA Affiliate has
failed to make any contribution or pay any amount due or owing as required by
the terms of any Plan. There are no pending or, to the best of the Company's
knowledge, threatened claims, lawsuits, investigations or actions (other than
routine claims for benefits in the ordinary course) asserted or instituted
against the assets of any Plan or its related trust or against any fiduciary of
a Plan with respect to the operation of such Plan that are likely to result in
liability of the Company that in the reasonable determination of the Company
would impair the ability of the Company to perform its payment or other material
obligations under the Loan Documents. Except in such instances where an omission
or failure would not in the reasonable determination of the Company impair the
ability of the Company to perform its payment or other material obligations
under the Loan Documents, each Plan maintained by the Company or an ERISA
Affiliate that is intended to be "qualified" within the meaning of section
401(a) of the Code is, and has been during the period from its adoption to date,
so qualified, both as to form and operation and all necessary governmental
approvals, including a favorable determination as to the qualification under the
Code of such Plan and each amendment thereto, have been or will be timely
obtained. Neither the Company nor any ERISA Affiliate has engaged in any
prohibited transaction, within the meaning of section 406 of ERISA or section
4975 of the Code, in connection with any Plan which could result in liability of
the Company that would in the reasonable determination of the Company impair the
ability of the Company to perform its payment or other material obligations
under the Loan Documents. Neither the Company nor any ERISA Affiliate has any
contingent liability with respect to any post-retirement benefits under a
welfare benefit plan as defined in ERISA other than a liability for continuation
coverage described in Part 6 of Title 1 of ERISA, except where such liability
could not in the reasonable determination of the Company be expected to impair
the ability of the Company to perform its payment or other material obligations
under the Loan Documents. Neither the Company nor any ERISA Affiliate maintains,
has established or has ever participated in a multiple employer welfare benefit
arrangement within the meaning of ERISA except to the extent that such
participation would not in the reasonable determination of the Company be
expected to impair the ability of the Company to perform its payment or other
material obligations under the Loan Documents. The Company has not incurred any
potential liability with respect to a multiemployer plan, as defined in section
3(37) of ERISA or a plan described in section 4063(a) of ERISA except to the
extent that such liability would not in the reasonable determination of the
Company be expected to impair the ability of the Company to perform its payment
or other material obligations under the Loan Documents. Neither the Company nor
any ERISA Affiliate has incurred any liability under Title IV of ERISA that has
not been satisfied, and no condition exists that could reasonably be expected to
result in the Company or an ERISA Affiliate incurring any liability under Title
IV of

                                      -53-
<PAGE>
ERISA that would in the reasonable determination of the Company impair the
ability of the Company to perform its payment or other material obligations
under the Loan Documents.

4.12 ENVIRONMENTAL PROTECTION.

         A. All Facilities and operations of the Company and its Subsidiaries
are, and have been to the Company's knowledge, in compliance with all
Environmental Laws except for any noncompliance which, individually or in the
aggregate, could not in the reasonable determination of the Company be expected
to impair the ability of the Company to perform its payment or other material
obligations under the Loan Documents.

         B. There are no, and have been no, conditions, occurrences, or
Hazardous Materials Activity (a) arising at any Facilities or, to the knowledge
of the Company, at any other location or (b) arising in connection with the
operations of the Company or its Subsidiaries (including the transportation of
Hazardous Materials in accordance with applicable regulations), which
conditions, occurrences or Hazardous Materials Activity could reasonably be
expected to form the basis of an Environmental Claim against the Company or any
of its Subsidiaries and which, individually or in the aggregate, could in the
reasonable determination of the Company be expected to impair the ability of the
Company to perform its payment or other material obligations under the Loan
Documents.

         C. To the Company's knowledge, there are no pending or threatened
Environmental Claims against the Company or its Subsidiaries, and the Company
and its Subsidiaries have received no notices, inquiries, or requests for
information with respect to any Environmental Claims which in either case are
reasonably likely to be adversely determined and could individually or in the
aggregate in the reasonable determination of the Company be expected to impair
the ability of the Company to perform its payment or other material obligations
under the Loan Documents.

         D. Except as disclosed to the Agent in writing, the Company is not
currently operating or required to be operating under any compliance order,
schedule, decree or agreement, any consent decree, order or agreement, and/or
any corrective action decree, order or agreement issued or entered into under
any Environmental Law the failure to comply with which could individually or in
the aggregate in the reasonable determination of the Company be expected to
impair the ability of the Company to perform its payment or other material
obligations under the Loan Documents.

         E. The Company has provided the Agent copies of all environmental
audits, assessments or other evaluations in its possession or subject to its
control prepared with respect to the Maintenance Facility, except for audits,
assessments or other evaluations that are confidential and privileged as
attorney-client communication.

proceeds of the Government Guaranteed Loan, the Company is and, upon the
incurrence of any Obligations by the Company on any date on which this
representation is made, will be, Solvent.

4.14 DISCLOSURE.

         No representation or warranty of the Company contained in any Loan
Document or in any other document, certificate or written statement furnished to
the Agent or Lenders by or on behalf of the Company or any of its Subsidiaries
for use in connection with the transactions contemplated by this Agreement
contains any untrue statement as and when made, as any of such representations
and warranties may made from time to time in accordance with this Agreement and
the other Loan Documents. Any projections and pro forma financial information
contained in such materials are based upon good faith estimates and assumptions
believed by the Company to be reasonable at the time made, it being recognized
by Lenders that such projections as to future events are not to be viewed as
facts and that actual results during the period or periods covered by any such
projections may differ from the projected results. There are no facts known to
any Responsible Officer of the Company (other than matters of a general economic
nature) that, individually or in the aggregate, could in the reasonable
determination of the Company be expected to impair the ability of the Company to
perform its payment or other material obligations under the Loan Documents.

4.15 YEAR 2000 MATTERS.

         Any reprogramming required to permit the proper functioning (but only
to the extent that such proper functioning would otherwise be impaired by the
occurrence of the year 2000) in and following the year 2000 of computer systems
and other equipment containing embedded microchips, whether owned or operated by
the Company or any of its Subsidiaries or used or relied upon in the conduct of
their business (including any such systems and other equipment supplied by
others or with which the computer systems of the Company or any of its
Subsidiaries interface), and the testing of all such systems and other equipment
as so reprogrammed, has been completed on or prior to the Closing Date, except
for such reprogramming the failure to perform any of which could not
individually or in the aggregate in the reasonable determination of the Company
be expected to impair the ability of the Company to perform its payment or other
material obligations under the Loan Documents.

         The documentation provided to the Agent relating to the receivables
pledged to the Agent for the benefit of the Lenders pursuant to the Receivables

or other material obligations under the Loan Documents. Neither the Company nor

of the Concessions as a whole to the Company would be reduced as a result of
such amendments, waivers or modifications by more than $120.0 million (on a net
present value basis) in the aggregate, as determined in good faith by the
Company. The Company shall perform each of its material obligations under the
Air Carrier Guarantee Loan Documents, the Lease Indenture and the Concessions,
in each case strictly in accordance with the terms thereof.

                                      AGENT

8.1 APPOINTMENT.

         The Industrial Bank of Japan, Limited, is hereby appointed the Agent
hereunder and under the other Loan Documents and each Lender hereby authorizes
the Agent to act as its agent in accordance with the terms of this Agreement and
the other Loan Documents. The Agent agrees to act upon the express conditions
contained in this Agreement and the other Loan Documents, as applicable. The
provisions of this Section 8 (except subsections 8.5 and 8.6) are solely for the
benefit of the Agent, and the Lenders, and the Company shall have no rights as a
third party beneficiary of any of the provisions thereof. In performing its
functions and duties under this Agreement, the Agent shall act solely as an
agent of the Lenders and does not assume and shall not be deemed to have assumed
any obligation towards or relationship of agency or trust with or for the
Company or any of its Subsidiaries.

8.2 POWERS AND DUTIES; GENERAL IMMUNITY.

         A. POWERS; DUTIES SPECIFIED. Each Lender irrevocably authorizes the
Agent to take such action on such Lender's behalf and to exercise such powers,
rights and remedies hereunder and under the other Loan Documents as are
specifically delegated or granted to the Agent by the terms hereof and thereof,
together with such powers, rights and remedies as are reasonably incidental
thereto. The Agent shall have only those duties and responsibilities that are
expressly specified in this Agreement and the other Loan Documents. The Agent
may exercise such powers, rights and remedies and perform such duties by or
through its agents or employees. The Agent shall not have, by reason of this
Agreement or any of the other Loan Documents, a fiduciary relationship in
respect of any Lender; and nothing in this Agreement or any of the other Loan
Documents, expressed or implied, is intended to or shall be so construed as to
impose upon the Agent any obligations in respect of this Agreement or any of the
other Loan Documents except as expressly set forth herein or therein.

                                      -73-
<PAGE>
         B. NO RESPONSIBILITY FOR CERTAIN MATTERS. The Agent shall not be
responsible to any Lender for the execution, effectiveness, genuineness,
validity, enforceability, collectibility or sufficiency of this Agreement or any
other Loan Document or for any representations, warranties, recitals or
statements made herein or therein or made in any written or oral statements or
in any financial or other statements, instruments, reports or certificates or
any other documents furnished or made by the Agent to the Lenders or by or on
behalf of the Company to the Agent or any Lender in connection with the Loan
Documents and the transactions contemplated thereby or for the financial
condition or business affairs of the Company or any other Person liable for the
payment of any Obligations, nor shall the Agent be required to ascertain or
inquire as to the performance or observance of any of the terms, conditions,
provisions, covenants or agreements contained in any of the Loan Documents or as
to the use of the proceeds of the Loans or as to the existence or possible
existence of any Event of Default or Potential Event of Default. Anything
contained in this Agreement to the contrary notwithstanding, the Agent shall not
have any liability arising from confirmations of the amount of outstanding Loans
or the component amounts thereof.

         C. EXCULPATORY PROVISIONS. Neither the Agent nor any of its officers,
directors, employees or agents shall be liable to the Lenders for any action
taken or omitted by the Agent under or in connection with any of the Loan
Documents except to the extent caused by their respective gross negligence or
willful misconduct. If the Agent shall request instructions from the Lenders
with respect to any act or action (including the failure to take an action) in
connection with this Agreement or any of the other Loan Documents, the Agent
shall be entitled to refrain from such act or taking such action unless and
until the Agent shall have received instructions from the Requisite Lenders.
Without prejudice to the generality of the foregoing, (i) the Agent shall be
entitled to rely, and shall be fully protected in relying, upon any
communication, instrument or document believed by it to be genuine and correct
and to have been signed or sent by the proper person or persons, and shall be
entitled to rely and shall be protected in relying on opinions and judgments of
attorneys (who may be attorneys for the Company and its Subsidiaries),
accountants, experts and other professional advisors selected by it; and (ii) no
Lender shall have any right of action whatsoever against the Agent as a result
of the Agent acting or (where so instructed) refraining from acting under this
Agreement or any of the other Loan Documents in accordance with the instructions
of Requisite Lenders. The Agent shall be entitled to refrain from exercising any
power, discretion or authority vested in it under this Agreement or any of the
other Loan Documents unless and until it has obtained the instructions of the
Requisite Lenders.

         D. AGENT ENTITLED TO ACT AS LENDER. The agency hereby created shall in
no way impair or affect any of the rights and powers of, or impose any duties or
obligations upon, the Agent in its individual capacity as a Lender hereunder.
With respect to its participations in the Loans, the Agent shall have the same
rights and powers hereunder as any other Lender and may exercise the same as
though it were not performing the duties and functions delegated to it
hereunder, and the term "Lender" or "Lenders" or any similar term shall, unless
the context clearly otherwise indicates, include the Agent in its individual
capacity. The Agent and its Affiliates may accept deposits from, lend money to
and generally engage in any kind of banking, trust, financial advisory or other
business with the Company or any of its Affiliates as if it were not performing
the duties specified herein, and may accept fees and other consideration from
the

                                      -74-
<PAGE>
Company for services in connection with this Agreement and otherwise without
having to account for the same to the Lenders.

8.3 REPRESENTATIONS AND WARRANTIES; NO RELIANCE.

         Each Lender represents and warrants that it has made its own
independent investigation of the financial condition and affairs of the Company
and its Subsidiaries in connection with the making and maintaining of the Loans
hereunder and that it has made and shall continue to make its own analysis of
the creditworthiness of the Company and its Subsidiaries. The Agent shall not
have any duty or responsibility, either initially or on a continuing basis, to
make any such investigation or any such appraisal on behalf of Lenders or to
provide any Lender with any credit or other information with respect thereto,
whether coming into its possession before the making of the Loans on the Closing
Date or at any time or times thereafter, and the Agent shall not have any
responsibility with respect to the accuracy of or the completeness of any
information provided to the Lenders.

8.4 RIGHT TO INDEMNITY.

         Each Lender, in proportion to its Pro Rata Share, severally agrees to
indemnify the Agent (and their respective affiliates and partners), to the
extent that the Agent shall not have been reimbursed by the Company, for and
against any and all liabilities, obligations, losses, damages, penalties,
actions, judgments, suits, costs, expenses (including, without limitation,
counsel fees and disbursements) or disbursements of any kind or nature
whatsoever which may be imposed on, incurred by or asserted against the Agent in
exercising their respective powers, rights and remedies or performing their
respective duties hereunder or under the other Loan Documents or otherwise in
its capacity as Agent, in any way relating to or arising out of this Agreement
or the other Loan Documents; provided 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 Agent's
gross negligence or willful misconduct.

8.5 SECURITY AGREEMENTS.

         Without limiting the generality of subsection 8.1, each Lender hereby
further authorizes the Agent to enter into the Security Agreements as secured
party on behalf of and for the benefit of such Lender and agrees to be bound by
the terms of each of the Security Agreements; provided that, except as otherwise
provided below, the Agent shall not enter into or consent to any amendment,
modification, termination or waiver of any provision contained in any Security
Agreement without prior written consent of the Requisite Lenders. Anything
contained in any of the Loan Documents to the contrary notwithstanding, each
Lender agrees that no Lender shall have any right individually to realize upon
any of the Collateral under any Security Agreement, it being understood and
agreed that all powers, rights and remedies under the Security Agreements may be
exercised solely by the Agent for the benefit of Lenders in accordance with the
terms thereof. Each Lender hereby authorizes the Agent (i) to release or
subordinate Collateral as permitted or required under this Agreement or the
Security Agreements, and agrees that a certificate executed by the Agent
evidencing such release of Collateral shall be conclusive evidence of such
release as to any third party and (ii) to enter into any amendments of the

                                      -75-
<PAGE>
Security Agreements to cure any ambiguity, defect or inconsistency or to amend
provisions relating to ministerial or administrative matters which do not
materially adversely affect the rights of the Lenders thereunder.

8.6 SUCCESSOR AGENT.

         The Agent may resign at any time by giving 30 days' prior written
notice thereof to the Lenders and the Company and may be removed at any time
with cause by the Required Lenders, such resignation or removal to be effective
only upon acceptance of its appointment of a successor Agent as provided herein.
Upon any such notice of resignation or removal, the Requisite Lenders shall have
the right to appoint a successor Agent and shall notify the Company in writing
of such appointment; provided, that, unless a Potential Event of Default or
Event of Default shall have occurred and then be continuing, the Required
Lenders shall obtain the Company's written consent to the appointment of such
successor Agent (such consent not to be unreasonably withheld or delayed). Upon
the acceptance of any appointment hereunder by a successor Agent, that successor
Agent shall thereupon succeed to and become vested with all the rights, powers,
privileges and duties of the retiring Agent and the retiring or removed Agent
shall be discharged from its duties and obligations under this Agreement. After
any retiring Agent's resignation or removal hereunder as Agent, the provisions
of this Section 8 shall inure to its benefit as to any actions taken or omitted
to be taken by it while it was the Agent under this Agreement.

                                   SECTION 9.
                                  MISCELLANEOUS

9.1 ASSIGNMENTS AND PARTICIPATIONS IN LOANS.

         A. GENERAL. Each Lender shall have the right at any time to (i) subject
to compliance with subsection 9.1B(i), sell, assign or transfer to any Eligible
Assignee, or (ii) sell participations to any Person in, all or any part of its
Loans made by it or any other interest herein or in any other Obligations owed
to it; provided that no such sale, assignment, transfer or participation shall
require the Company to file a registration statement with the Securities and
Exchange Commission or apply to qualify such sale, assignment, transfer or
participation under the securities laws of any state; provided, further that no
such sale, assignment or transfer described in clause (i) above shall be
effective unless and until an Assignment Agreement effecting such sale,
assignment or transfer shall have been accepted by the Agent and recorded in the
Register as provided in subsection 9.1B(ii). Except as otherwise provided in
this subsection 9.1, no Lender shall, as between the Company and such Lender, be
relieved of any of its obligations hereunder as a result of any sale, assignment
or transfer of, or any granting of participations in, all or any part of its
Loans or the other Obligations owed to such Lender.

         B. ASSIGNMENTS.

                  (i) Amounts and Terms of Assignments. Each Loan or other
         Obligation may (a) be assigned in any amount to another Lender, or to
         an Affiliate of the assigning Lender or another Lender, with the giving
         of notice to the Company and the Agent or (b)

                                      -76-
<PAGE>
         be assigned in an aggregate amount of not less than $5,000,000 (or such
         lesser amount as shall constitute the aggregate amount of the Loans,
         and other Obligations of the assigning Lender) to any other Eligible
         Assignee with the consent of the Agent (which consent shall not be
         unreasonably withheld or delayed). To the extent of any such assignment
         in accordance with either clause (a) or (b) above, the assigning Lender
         shall be relieved of its obligations thereafter arising with respect to
         its Loans, or other Obligations or the portion thereof so assigned. The
         parties to each such assignment shall execute and deliver to the Agent,
         for its acceptance and recording in the Register, an Assignment
         Agreement, together with a processing and recordation fee of $3,500 and
         such forms, certificates or other evidence, if any, with respect to
         United States federal income tax withholding matters as the assignee
         under such Assignment Agreement may be required to deliver to the Agent
         pursuant to subsection 2.7B(iii)(a). Upon such execution, delivery and
         acceptance, from and after the effective date specified in such
         Assignment Agreement, (y) the assignee thereunder shall be a party
         hereto and, to the extent that rights and obligations hereunder have
         been assigned to it pursuant to such Assignment Agreement, shall have
         the rights and obligations of a Lender hereunder and (z) the assigning
         Lender thereunder shall, to the extent that rights and obligations
         hereunder have been assigned by it pursuant to such Assignment
         Agreement, relinquish its rights and be released from its obligations
         thereafter arising under this Agreement (and, in the case of an
         Assignment Agreement covering all or the remaining portion of an
         assigning Lender's rights and obligations under this Agreement, such
         Lender shall cease to be a party hereto). The assigning Lender shall,
         upon the effectiveness of such assignment or as promptly thereafter as
         practicable, surrender its applicable Notes to the Agent for
         cancellation, and thereupon new Notes shall be issued to the assignee
         substantially in the form of Exhibit III and Exhibit III-A annexed
         hereto, as the case may be, with appropriate insertions, to reflect the
         outstanding Loans, as the case may be, of the assignee and/or the
         assigning Lender. If a Lender assigns all some or of its Term Note,
         such Lender must also assign a like portion of such Lender's PIK Note
         to the same Eligible Assignee. No Lender may assign any of its PIK Note
         without an assignment of some or all of its Term Note as permitted
         hereunder.

                  (ii) Acceptance by the Agent; Recordation in Register. Upon
         its receipt of an Assignment Agreement executed by an assigning Lender
         and an assignee representing that it is an Eligible Assignee, together
         with the processing and recordation fee referred to in subsection
         9.1B(i) and any forms, certificates or other evidence with respect to
         United States federal income tax withholding matters that such assignee
         may be required to deliver to the Agent pursuant to subsection
         2.7B(iii)(a), the Agent shall, if such Assignment Agreement has been
         completed and is in substantially the form of Exhibit VI hereto and if
         the Agent has consented to the assignment evidenced thereby, (a) accept
         such Assignment Agreement by executing a counterpart thereof as
         provided therein (which acceptance shall evidence any required consent
         of the Agent to such assignment), (b) record the information contained
         therein in the Register and (c) give prompt notice thereof to the
         Company. The Agent shall maintain a copy of each Assignment Agreement

         9.1B(ii).

         C. PARTICIPATIONS. No participation granted hereunder shall relieve the
granting Lender from its obligations hereunder and the Agent, the Company and
other Lenders shall continue to deal solely and directly with such Lender in
connection with such Lender's rights and obligations under this Agreement and
the other Loan Documents, provided, however, that (i) the selling Lender's
obligations under this Agreement shall remain unchanged, (ii) such Lender shall
remain solely responsible to the other parties hereto for the performance of
such obligations, (iii) the participating banks or other entities shall be
entitled to the provisions of subsections 2.6, 2.7, 9.3 and 9.5, provided,
however, that the costs to which a participant shall be entitled to obtain
pursuant thereto shall be determined by reference to such participant's selling
Lender and shall be recoverable solely from such selling Lender and (iv) the
Company, the Agent and the other Lenders shall continue to deal solely and
directly with the selling Lender in connection with such Lender's rights and
obligations under this Agreement and the other Loan Documents; provided,
however, as between the selling Lender and any such participant, the selling
Lender may grant such participant rights with respect to amendments,
modifications or waivers with respect to any fees payable hereunder to such
Lender (including the amount and the dates fixed for the payment of any such
fees) or the amount of principal or the rate of interest payable on, or the
release of any obligations of the Company hereunder and under the other Loan
Documents. No participant shall be a third party beneficiary of this Agreement
and shall not be entitled to enforce any rights provided to its selling Lender
against the Company under this Agreement.

         D. ASSIGNMENTS TO FEDERAL RESERVE BANKS. In addition to the assignments
and participations permitted under the foregoing provisions of this subsection
9.1, any Lender may assign and pledge all or any portion of its Loans, the other
Obligations owed to such Lender, and its Notes to any Federal Reserve Bank as
collateral security pursuant to Regulation A of the Board of Governors of the
Federal Reserve System and any operating circular issued by such Federal Reserve
Bank; provided that (i) no Lender shall, as between the Company and such Lender,
be relieved of any of its obligations hereunder as result of any such assignment
and pledge and (ii) in no event shall such Federal Reserve Bank be considered to
be a "Lender" or be entitled to require the assigning Lender to take or omit to
take any action hereunder.

         E. INFORMATION. Each Lender may furnish any information concerning the
Company and its Subsidiaries in the possession of that Lender from time to time
to assignees and participants (including prospective assignees and

expenses of preparation of the Loan Documents; (ii) all the costs of furnishing

payments due from the Company hereunder or under the other Loan Documents by
reason of any Event of Default or Potential Event of Default or in connection
with any refinancing or restructuring of the credit arrangements provided under
this Agreement in the nature of a "work-out" or pursuant to any insolvency or
bankruptcy proceedings.

9.3 INDEMNITY.

         Subject to the limitations in subsection 9.2 with respect to the
matters specified therein, and without duplication of the provisions of the
Environmental Indemnity Agreement, Section 2.11 of any Aircraft Security
Agreement and Section 3.06 of the Spare Engine Security Agreement, whether or
not the transactions contemplated hereby shall be consummated, the Company
agrees to defend, indemnify, pay and hold harmless the Agent, the Lenders, the
Co-Lead Book Managers, the Syndication Agent, the Arrangers and the
Documentation Agent and the officers, directors, employees, agents and
affiliates of the Agent, the Lenders, the Co-Lead Book Managers, the Syndication
Agent, the Arrangers and the Documentation Agent (collectively called the
"INDEMNITEES") from 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 counsel for such Indemnitees), whether
direct, indirect or consequential and whether based on any federal, state or
foreign laws, statutes, rules or regulations (including without limitation
securities and commercial laws, statutes and rules or regulations), on common
law or equitable cause or on contract or otherwise, 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 Lenders' agreement to
maintain the Loans hereunder or the use or intended use of the proceeds of the
Loans) or any breach or default by the Company of any provision of the Loan
Documents (collectively called the "INDEMNIFIED LIABILITIES"); provided that the
Company shall not have any obligation to any Indemnitee hereunder with respect
to any Indemnified Liabilities to the extent such Indemnified Liabilities arise
(i) from the gross negligence or willful misconduct of that Indemnitee, (ii)
constitute ordinary and usual operating or overhead expenses of an Indemnitee
(excluding , without limitation, costs and expenses of any outside counsel,
consultant or agent) and (iii) arise out of the breach of any obligation or
representation of an Indemnitee in this Agreement or any other Loan Document.
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 Company shall contribute the maximum portion
that it is permitted to pay and satisfy under applicable law

                                      -79-
<PAGE>
to the payment and satisfaction of all Indemnified Liabilities incurred by the
Indemnitees or any of them.

9.4 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 consent permitted by
law, each Lender and is hereby authorized by the Company at any time or from
time to time, without notice to the Company 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 the Company against and on account of the
obligations and liabilities of the Company to that Lender under this Agreement,
the Notes, and the other Loan Documents, including, but not limited to, all
claims of any nature or description arising out of or connected with this
Agreement, the Notes, or any other Loan Document, irrespective of whether or not
(i) that Lender shall have made any demand hereunder or (ii) the principal of or
the interest on the Loans or any other amounts due hereunder shall have become
due and payable pursuant to Section 7 and although said obligations and
liabilities, or any of them, may be contingent or unmatured.

9.5 RATABLE SHARING.

         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 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, the "AGGREGATE
AMOUNTS DUE" to such Lender) which is greater than the proportion received by
any other Lender in respect of the Aggregate Amounts Due to such other Lender,
then the Lender receiving such proportionately greater payment shall (i) notify
the 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 Company 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 Company expressly consents 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 Company to that holder with respect thereto as fully as if
that holder were owed the amount of the participation held by that holder.

9.6 AMENDMENTS AND WAIVERS.

         A. No amendment, modification, termination or waiver of any provision
of this Agreement or of the Notes, or consent to any departure by the Company
therefrom, shall in any event be effective without the written concurrence of
Requisite Lenders; provided that any such amendment, modification, termination,
waiver or consent which: increases the principal amount of any of the Loans;
changes any Lender's Pro Rata Share; changes in any manner the definition of
"Requisite Lenders"; changes in any manner any provision of this Agreement
which, by its terms, expressly requires the approval or concurrence of all
Lenders; postpones the scheduled final maturity date of any of the Loans;
postpones the date or reduces the amount of any scheduled payment (but not
prepayment) of principal of any of the Loans; postpones the date on which any
interest or any fees are payable; waives a mandatory prepayment of principal
owed as a result of a Borrowing Base Deficiency for a period in excess of 30
days from the date the Company notifies the Agent of the existence of a
Borrowing Base Deficiency; decreases the interest rate borne by any of the Loans
(other than any waiver of any increase in the interest rate applicable to any of
the Loans pursuant to subsection 2.2E) or the amount of any fees payable
hereunder; increases the maximum duration of Interest Periods permitted
hereunder; releases all or substantially all of the Collateral (except as
expressly provided in the Security Agreements); or changes in any manner the
provisions contained in subsection 7.1 or this subsection 9.6 shall be effective
only if evidenced by a writing signed by or on behalf of all Lenders to whom are
owed Obligations being directly affected by such amendment, modification,
termination, waiver or consent. In addition, (i) any amendment, modification,
termination or waiver of any of the provisions contained in Section 3 shall be
effective only if evidenced by a writing signed by or on behalf of the Agent and
Requisite Lenders, (ii) no amendment, modification, termination or waiver of any
provision of any Note shall be effective without the written concurrence of the
Lender which is the holder of that Note, and (iii) no amendment, modification,
termination or waiver of any provision of Section 8 or of any other provision of
this Agreement which, by its terms, expressly requires the approval or
concurrence of the Agent shall be effective without the written concurrence of
the Agent. The Agent may, but shall have no obligation to, with the 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 Company in any case shall entitle the Company to any other or
further notice or demand in similar or other circumstances. Any amendment,
modification, termination, waiver or consent effected in accordance with this
subsection 9.6 shall be binding upon each Lender at the time outstanding, each
future Lender and, if signed by the Company, on the Company.

         B. If, in connection with any proposed change, waiver, discharge or
termination to any of the provision of this Agreement as contemplated by the
provision in the first sentence of this subsection 9.6, the consent of Requisite
Lenders is obtained but consent of one or more of such other Lenders whose
consent is required is not obtained, then the Company may, so long as all
non-consenting Lenders are so treated, elect to terminate such Lender as a party
to this Agreement; provided that, concurrently with such termination, (i) the
Company shall pay that Lender all principal, interest and fees and other amounts
owed to such Lender through such date of termination, (ii) another financial
institution satisfactory to the Company and the Agent (or if the Agent is also
the Lender to be terminated, the successor Agent) shall agree, as of such date,
to

                                      -81-
<PAGE>
become a Lender for all purposes under this Agreement (whether by assignment or
amendment) and to assume all obligations of the Lender to be terminated as of
such date, and (iii) all documents and supporting materials necessary, in the
judgment of the Agent (or if the Agent is also the Lender to be terminated, the
successor Agent) to evidence the substitution of such Lender shall have been
received and approved by the Agent as of such date.

9.7 INDEPENDENCE OF COVENANTS.

         All covenants under this Agreement shall be given independent effect so
that if a particular action or condition is not permitted by any of such
covenants, the fact that it would be permitted by an exception to, or would
otherwise be within the limitations of, another covenant shall not avoid the
occurrence of an Event of Default or Potential Event of Default if such action
is taken or condition exists.

9.8 NOTICES.

         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 of telefacsimile, or five Business Days
after depositing it in the United States mail with postage prepaid and properly
addressed; provided that notices shall not be effective until received. For the
purposes hereof, the address of each party hereto shall be as set forth under
such party's name on the signature pages hereof or (i) as to the Company and the
Agent, such other address as shall be designated by such Person in a written
notice delivered to the other parties hereto and (ii) as to each other party,
such other address as shall be designated by such party in a written notice
delivered to the Agent.

9.9 SURVIVAL OF REPRESENTATIONS, WARRANTIES AND AGREEMENTS.

         A. All representations, warranties and agreements made herein shall
survive the execution and delivery of this Agreement and the making of the Loans
hereunder.

         B. Notwithstanding anything in this Agreement or implied by law to the
contrary, (x) the agreements of the Company set forth in subsection 9.3 and the
agreements of the Lenders set forth in subsections 8.2C, 8.4 and 9.5 shall
survive the payment of the Loans, and the termination of this Agreement and (y)
the agreements of the Company set forth in subsections 2.6D, 2.7, 9.2 and 9.4
shall survive the payment of the Loans, and the termination of this Agreement
for a period of two years.

9.10 FAILURE OR INDULGENCE NOT WAIVER; REMEDIES CUMULATIVE.

         No failure or delay on the part of the Agent or any Lender in the
exercise of any power, right or privilege hereunder or under any other Loan
Document shall impair such power, right or privilege or be construed to be a
waiver of any default or acquiescence therein, nor shall any single or partial
exercise of any such power, right or privilege preclude other or further
exercise thereof or of any other power, right or privilege. All rights and
remedies existing under this

                                      -82-
<PAGE>
Agreement and the other Loan Documents are cumulative to, and not exclusive of,
any rights or remedies otherwise available.

9.11 MARSHALING; PAYMENTS SET ASIDE.

         Neither the Agent nor any Lender shall be under any obligation to
marshal any assets in favor of the Company or any other party or against or in
payment of any or all of the Obligations. To the extent that the Company makes a
payment or payments to the Agent or the Lenders (or to the Agent for the benefit
of the Lenders), or the Agent or Lenders enforce any security interests or
exercise their rights of set-off, and such payment or payments or the proceeds
of such enforcement or set-off or any part thereof are subsequently invalidated,
declared to be fraudulent or preferential, set aside and/or required to be
repaid to a trustee, receiver or any other party under any bankruptcy law, any
other state or federal law, common law or any equitable cause, then, to the
extent of such recovery, the obligation or part thereof originally intended to
be satisfied, and all Liens, rights and remedies therefor or related thereto,
shall be revived and continued in full force and effect as if such payment or
payments had not been made or such enforcement or set-off had not occurred.

9.12 SEVERABILITY.

         In case any provision in or obligation under this Agreement or the
Notes shall be invalid, illegal or unenforceable in any jurisdiction, the
validity, legality and enforceability of the remaining provisions or
obligations, or of such provision or obligation in any other jurisdiction, shall
not in any way be affected or impaired thereby.

9.13 OBLIGATIONS SEVERAL; INDEPENDENT NATURE OF LENDERS' RIGHTS.

         The obligations of the Lenders hereunder are several and no Lender
shall be responsible for the obligations of any other Lender hereunder. None of
the Arrangers, Syndication Agent, Documentation Agent or the Co-Lead Book
Managers in their respective capacities as such shall have any duties or
responsibilities under this Agreement or the other Loan Documents. Nothing
contained herein or in any other Loan Document, and no action taken by Lenders
pursuant hereto or thereto, shall be deemed to constitute Lenders as a
partnership, an association, a joint venture or any other kind of entity. The
amounts payable at any time hereunder to each Lender shall be a separate and
independent debt.

9.14 HEADINGS.

         Section and subsection headings in this Agreement are included herein
for convenience of reference only and shall not constitute a part of this
Agreement for any other purpose or be given any substantive effect.

hereto and the successors and assigns of the Lenders. Except as provided in
subsections 6.6(v), 6.10 and 6.12, neither the Company's rights or obligations
hereunder nor any interest therein may be assigned or delegated by the Company
without the prior written consent of all Lenders.

9.17 CONSENT TO JURISDICTION AND SERVICE OF PROCESS.

         ALL JUDICIAL PROCEEDINGS BROUGHT AGAINST ANY PARTY HERETO ARISING OUT
OF OR RELATING TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT OR ANY OBLIGATION
MAY BE BROUGHT IN ANY STATE OR FEDERAL COURT OF COMPETENT JURISDICTION IN THE

PARTY ACCEPTS FOR ITSELF AND IN CONNECTION WITH ITS PROPERTIES, GENERALLY AND
UNCONDITIONALLY, THE NONEXCLUSIVE JURISDICTION OF THE AFORESAID COURTS AND

appoints CT Corporation System, 1633 Broadway, New York, New York 10019, as its
agent for service of process and agrees that service of process upon such agent
shall be deemed to be service of process upon the Company with respect to any
proceeding related to the Loan Documents. Nothing herein shall affect the right
to serve process in any other manner permitted by law or shall limit the right
of any Lender or the Agent to bring proceedings against the Company in the
courts of any other jurisdiction.

9.18 WAIVER OF JURY TRIAL.

         EACH OF THE PARTIES TO THIS AGREEMENT HEREBY AGREES TO WAIVE ITS
RESPECTIVE RIGHTS TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION BASED UPON OR
ARISING OUT OF THIS AGREEMENT OR ANY OF THE OTHER LOAN DOCUMENTS OR ANY DEALINGS
BETWEEN THEM RELATING TO THE SUBJECT MATTER OF THIS LOAN TRANSACTION OR THE
LENDER/BORROWER RELATIONSHIP THAT IS BEING ESTABLISHED. The scope of this waiver
is intended to be all-encompassing of any and all disputes that may be filed in
any court and that relate to the subject matter of this transaction, including
without limitation contract claims, tort claims, breach

                                      -84-
<PAGE>
of duty claims and all other common law and statutory claims. Each party hereto
acknowledges that this waiver is a material inducement to enter into a business
relationship, that each has already relied on this waiver in entering into this
Agreement, and that each will continue to rely on this waiver in their related
future dealings. Each party hereto further warrants and represents that it has
reviewed this waiver with its legal counsel and that it knowingly and
voluntarily waives its jury trial rights following consultation with legal
counsel. THIS WAIVER SHALL APPLY TO ANY SUBSEQUENT AMENDMENTS, RENEWALS,

this Agreement may be filed as written consent to a trial by the court.

to be unreasonably withheld or delayed, other than (a) to the Agent's or

judicial process and (c) as requested or required by any state, federal or
foreign authority or examiner regulating banks or banking.

         This Agreement and any amendments, waivers, consents or supplements
hereto or in connection herewith may be executed in any number of counterparts
and by different parties hereto in separate counterparts, each of which when so
executed and delivered shall be deemed an original, but all such counterparts
together shall constitute but one and the same instrument; signature pages may
be detached from multiple separate counterparts and attached to a single
counterpart so that all signature pages are physically attached to the same
document.

9.21 INTEGRATION.

         This Agreement, the Security Agreements, and the other agreements
executed in connection therewith constitute the entire understanding among the
parties hereto with respect to the matters covered thereby, and shall supersede
any prior agreements covering such matters.

9.22 DISCLAIMER OF DAMAGES.

         No Indemnitee shall have any liability (whether direct or indirect, in
contract, tort or otherwise) to the Company or any of its security holders or
creditors for or in connection with the transactions contemplated hereby, except

by a court of competent jurisdiction to be direct damages arising primarily

                                      -85-
<PAGE>
from such Indemnitee's gross negligence or willful misconduct. In no event shall

punitive damages (including, without limitation, any loss of profits, business

         Section 1.04 hereof are true and accurate on and as of the date of such
         Supplement with respect to such Replacement Engine and the Company as
         though made on and as of such date and (y) that the Company has
         complied with the conditions contained in Section 2.l0B(ii)(1) of the
         Credit Agreement;

         reasonably satisfactory to the Agent in form and substance reasonably
         satisfactory to the Agent that the Agent will have the benefit of
         Section 1110 under this Security Agreement with respect to such
         Replacement Engine.

                  Promptly upon the recordation of such Supplement with the FAA,
the Company will cause to be delivered to the Agent an opinion of counsel
acceptable to the Agent as to the due recording of such Supplement against such
Replacement Engine in accordance with the Act. Upon satisfaction of the
conditions of this Section 1.03B, the Replacement Engine shall become an
"Engine" for all purposes hereof and the engine being substituted for shall

         security agreement provides that engines such as the Engine shall not
         become subject to the lien of such lease, conditional
<PAGE>
         sale or other security agreement, notwithstanding the installation
         thereof on such airframe; and

                  3. lease the Aircraft to any Permitted Lessee provided that
         (A) such lease shall not have a term of more that six (6) months (or
         eighteen (18) months if at the time such lease is executed such

         insurance certificates and evidence complying with Section 2.04 (which
         insurance may be provided by the Permitted Lessee if it otherwise
         complies in all respects with Section 2.04 hereof).

                  The Agent agrees for the benefit of a lessor or secured party
under a lease, conditional sale or other security agreement containing an
agreement complying with Section 2.01(D)(2)(b) which lease, conditional sale or
security agreement also covers an engine or engines owned by the lessor under
such lease or subject to a security interest in favor of the secured party under
such conditional sale or other security agreement that the Agent will not
acquire or claim, as against such lessor or secured party, any right, title or
interest in any such engine or engines as the result of such engine or engines
being installed on the Airframe at any time while such engine or engines is
subject to such lease, conditional sale or other security agreement and owned by
such lessor or subject to a security interest in favor of such secured party.

thereof to the same extent as if such lease or transfer had not occurred. The
terms of any such lease shall not permit any lessee to take any action not
permitted to be taken by the Company under this Security Agreement with respect
to the Aircraft.

                  Any wet lease or similar arrangement under which the Company
provides the crew and maintains operational control of the Aircraft shall not
constitute a delivery, transfer or relinquishment of possession for purposes of
this Section 2.1(D).
<PAGE>
         E. Plates. On or before the date hereof, or as soon thereafter as
practicable, the Company agrees to affix and maintain in the cockpit of the

        SUBJECT TO A SECURITY INTEREST IN FAVOR OF THE INDUSTRIAL BANK OF
                   JAPAN, LIMITED, AS AGENT, SECURED CREDITOR

         F. Insignia. Nothing contained in the Credit Agreement or this Security
Agreement shall prohibit the Company from placing its customary colors and
insignia on the Airframe or any Engine or from otherwise operating the Aircraft
in its livery.

                  SECTION 2.02. Liens. The Company will not directly or
indirectly create, incur, assume or suffer to exist any Lien on or with respect
to the Aircraft, title thereto or any interest therein or part thereof other
than Permitted Liens. The Company will promptly, at its own expense, take (or
cause to be taken) such actions as may be necessary duly to discharge any Lien
not constituting a Permitted Lien if the same arise at any time.

                  SECTION 2.03. Parts.

         A. Replacement of Parts. The Company, at its own cost and expense, will
promptly replace or cause to be replaced all Parts which may from time to time
become worn out, lost, stolen, destroyed, seized, confiscated, damaged beyond
repair or permanently rendered unfit for use for any reason whatsoever, except
as otherwise provided in this Section 2.03(A) or Section 2.03(D) of this
Security Agreement. All replacement parts (other than replacement parts
temporarily installed as provided in Section 2.03(B) of this Security Agreement
shall be free and clear of all Liens (except Permitted Liens), and shall be in
as good an operating condition, and shall have a value and utility substantially
equal to or greater than, the Parts replaced assuming such replaced Parts were
in the condition and repair required to be maintained by the terms of this
Security Agreement. All Parts at any time removed from the Airframe or any
Engine shall remain the property of the Company, no matter where located, until
such time as such Parts shall be replaced by parts which meet the requirements
for replacement Parts specified above. Upon any replacement part becoming
incorporated or installed in or attached to the Airframe or any Engine, without
further act (subject only to Permitted Liens and any arrangement permitted by
Section 2.03(B) of this Security Agreement), (i) such replacement part shall
become the property of the Company and shall become subject to the Lien of this
Security Agreement and be deemed a Part for all purposes of this Security
Agreement to the same extent as the Parts originally incorporated or installed
in or attached to the Airframe or such Engine and (ii) the replaced Part shall
no longer be deemed a Part under this Security Agreement. Upon written request
and at the Company's expense, the Agent shall execute and deliver to the Company
such releases as the Company may reasonably request to effectuate the release
contemplated in clause (ii) of the previous sentence.

                  The Company may remove Parts which the Company determines in
its reasonable judgment to be obsolete or no longer suitable or appropriate for
use on the Airframe or any
<PAGE>
Engine (each, an "Obsolete Part"), provided that (i) such removal is being
applied by the Company on a fleet-wide basis and does not discriminate against
the Aircraft to the extent applicable having regard to the fleet and equipment
type and the age of the Aircraft and (ii) removal of any such Obsolete Parts
shall not diminish the value, utility or remaining useful life of the Airframe
or such Engine, or materially impair the condition or impair the airworthiness
thereof, below the value, utility, condition, airworthiness or remaining useful
life thereof immediately prior to such removal assuming the Airframe or such
Engine was then of the value and utility and in the condition and airworthiness
required to be maintained by the terms of this Security Agreement.

         B. Pooling of Parts; Temporary Replacement Parts. Any Part removed from
the Airframe or any Engine as provided in Section 2.03(A) of this Security
Agreement may be subjected by the Company to a normal pooling or similar
arrangement customary in the airline industry and entered into by the Company in
the ordinary course of its business; provided, that a Part replacing such
removed Part shall be incorporated or installed in or attached to such Airframe
or Engine in accordance with Section 2.03(A) of this Security Agreement as
promptly as practicable after the removal of such removed Part. In addition, the
Company may use temporary parts or pooled parts on the Aircraft as temporary
replacements for Parts, provided that the Company, at its expense as promptly
thereafter as practicable, either (1) causes such pooled or replacement part to
become the property of the Company free and clear of all Liens other than
Permitted Liens or (2) replaces such replacement part with a further replacement
part owned by the Company which meets the requirements of Section 2.03(A) of
this Security Agreement and which shall become the property of the Company, free
and clear of all Liens other than Permitted Liens.

         C. Modifications.

                  1. Except as provided in Section 2.01B(3) hereof, the Company
shall at its expense make such alterations and modifications in and additions to
the Airframe or any Engine as may be required to be made from time to time by
applicable law ("Required Modifications").

                  2. The Company shall not make any modifications, alterations
or additions (collectively, "Modifications") to the Aircraft, (other than
Required Modifications) which will result in adverse changes to the Aircraft
structure or performance or which will either (a) materially decrease the
utility, value or remaining useful life of the Aircraft or (b) adversely affect
the Aircraft's airworthiness or use for transporting passengers or cargo in
commercial service.

                  3. All Modifications shall be FAA-approved or in accordance
with the Approved Maintenance Program.

         D. Additional Parts. All parts incorporated or installed in or attached
or added to the Airframe or an Engine (other than passenger service items leased
to or owned by the Company including, without limitation, telephone or video
equipment, which such passenger service items
<PAGE>
shall not be considered "Parts") as the result of a Modification (the
"Additional Part" or "Additional Parts") shall, without further act, become the
property of the Company and subject to this Security Agreement. Notwithstanding
the foregoing, the Company may, at any time, so long as no Event of Default
shall have occurred and be continuing, remove or suffer to be removed any
Additional Part, provided that such Additional Part (x) (i) is in addition to,
and not in replacement of or substitution for, any Part originally incorporated
or installed in or attached to the Airframe or any Engine at the time of
delivery thereof hereunder or any Part in replacement of or substitution for any
such Part and (ii) can be removed from the Airframe or such Engine without
impairing the airworthiness of the Airframe or such Engine or diminishing the
value, utility or remaining useful life of the Airframe or such Engine which the
Airframe or such Engine would have had at such time had such alteration,
modification or addition not occurred or (y) such Part is an Obsolete Part. Upon
the removal thereof as provided above, such Additional Parts shall no longer be
deemed part of the Airframe or the Engine from which it was removed.

                  SECTION 2.04. Insurance.

         (a)      Public Liability and Property Damage Liability Insurance.

                  (i)      The Company, at its own cost and expense, will

         liability to third parties and/or passengers, passenger legal liability
         and property damage liability insurance and cargo legal liability in
         such amounts, against such risks (including, without limitation,
         contractual liability and war risk liability), with such retentions as
         the Company customarily maintains with respect to similar airframes and
         engines owned or operated by the Company (provided, however, that any
         self-insured retention and/or deductible shall not exceed [$1,000,000]
         per occurrence) (in the event that with the prior consent of the Agent
         such insurance contains the War, Hijacking, and Other Perils Exclusion
         Clause (AVN 48B), then there must be in place the Extended Coverage
         Endorsement protection offered by AVN 52 to include "Buy Back" of
         paragraphs C, D, E and G of AVN 48B (or coverage equal thereto under a
         separate policy)) and with such insurers or reinsurers (which shall be
         insurers or reinsurers of recognized responsibility), and insurance
         against such other risks as is usually carried by similar corporations
         engaged in the same or similar business and similarly situated as the
         Company and owning or operating airframes and engines similar to the
         Airframe and Engines; provided that such insurance shall not be in
         amounts less than $500,000,000 per occurrence.

                  (ii)     Notwithstanding Section 2.04(a)(i), in the event of
         the requisition for use by the United States government of any Airframe
         or Engine, the Company shall maintain throughout the period of such
         requisition such insurance as would otherwise be required under this
         Section 2.04, provided that the Agent shall accept, in lieu of such
         insurance
<PAGE>
         coverage, indemnification or insurance from the United States
         government which is substantially the same as otherwise required under
         this Section 2.04.

                  (ii)     Any policy of insurance carried and maintained in
         accordance with this Section 2.04(a), and any policy taken out in
         substitution or replacement for any such policy subject to the terms,
         conditions and limitations thereof, shall:

                                    (A)      name the initial Lenders and the
                  Agent and their respective successors and permitted assigns as
                  additional insureds (each an "Additional Insured");

                                    (B)      provide that, in respect of the
                  interest of any such Additional Insured in such policies, the
                  insurance shall not be invalidated by any action or inaction
                  of the Company or any Additional Insured as defined under the
                  policy of insurance required under this Section 2.04(a) (other
                  than such Additional Insured) and shall insure each such
                  Additional Insured regardless of any breach or violation of
                  any warranty, declaration or condition contained in such
                  policies by the Company or any other Additional Insured as
                  defined under the policy of insurance required under this
                  Section 2.04(a) (other than such Additional Insured);

                                    (C)      provide that if such insurance is
                  canceled for any reason, or any substantial change is made in
                  the policies which adversely affect the coverage required
                  herein, or if such insurance is allowed to lapse for
                  nonpayment of premium, such cancellation, change or lapse
                  shall not be effective as to any Additional Insured for 30
                  days (except in the case of war risk coverage in which event
                  the applicable period shall be seven days or such other period
                  as may be customary) after receipt by each such Additional
                  Insured of written notice from such insurers of such
                  cancellation, change or lapse;

                                    (D)      provide that no such Additional
                  Insured shall have any obligation or liability for premiums or
                  other payments, if any, in connection with such insurance;

                                    (E)      provide that the insurers shall
                  waive any rights of subrogation against each such Additional
                  Insured except to the extent that any insured event arises
                  solely from the gross negligence or willful misconduct of
                  such Additional Insured as determined by a final judgment of a
                  court of competent jurisdiction;

                                    (F)      provide that such insurer shall
                  waive the right of such insurer to any set-off or counterclaim
                  or any other deduction, whether by attachment or otherwise, in
                  respect of any liability of any such Additional Insured;
<PAGE>
                                    (G)      provide that all of the provisions
                  of such policy shall operate in the same manner as if there
                  were a separate policy covering each such Additional Insured;
                  provided that such policies shall not operate to increase any
                  insurer's limit of liability; and

                                    (H)      be primary, without right of
                  contribution from any other insurance which is carried by any
                  Additional Insured with respect to its interest in the Subject
                  Collateral.

         (b)      Insurance Against Loss or Damage to Subject Collateral. The
Company, at its own cost and expense, shall maintain or cause to be maintained
in effect, with insurers or reinsurers of recognized responsibility, all-risk
coverage, including ground and flight insurance on the Aircraft (with flight,
taxiing and ingestion coverages) with respect to any Aircraft, Engines and Parts
temporarily removed from the Airframe pending installation of the same or
similar Engines, engines, or Parts on the Airframe, including, war-risk and
allied perils insurance on the Aircraft in an amount not less than the Agreed
Value covering the perils of:

                  1. war, invasion, acts of foreign enemies, hostilities
(whether war be declared or not), civil war, rebellion, revolution,
insurrection, martial law, military or usurped power, or attempts at usurpation
of power;

                  2. strikes, riots, civil commotions or labor disturbances;

                  3. any act of one or more persons, whether or not agents of a
sovereign power, for political or terrorist purposes and whether the loss or
damage therefrom is accidental or intentional;

                  4. any malicious act or act of sabotage;

                  5. confiscation, nationalization, seizure, restraint,
detention, appropriation, requisition of title or use by or under the order of
any government (whether civil, military or de facto) or public or local
authority other than the government or any public or local authority of the
country of registration; and

                  6. hijacking or any unlawful seizure or wrongful seizure or
wrongful exercise of control of the Aircraft or crew in flight (including any
attempt at such seizure or control) made by any person or persons on board this
Aircraft acting without the consent of the Company.

                  Such insurance shall be in such form and amounts and with
such retentions as the Company customarily maintains with respect to similar
airframes and engines owned or operated by the Company, provided, however, that
(1) such retentions shall consist only of industry standard deductibles
(determined by the deductible applicable to the aircraft type) and with no
<PAGE>
self insurance, (2) each Airframe and Engine shall be insured in an amount not
less than its Agreed Value and (3) any reinsurance shall be on the same terms as
the primary insurance.

                  Any policies carried and maintained in accordance with this
Section 3.04(b) and any policies taken out in substitution or replacement for
any such policies subject to the terms, conditions and limitations thereof
shall:

                  (i)      name or be amended to name the then Lenders and the
         Agent and their respective successors and assigns as additional
         insureds and to name the Agent as loss payee (the "Loss Payee");

                  (ii)     provide with respect to coverage provided under this
         Section 3.04(b), that (A) in the event of a loss or damage involving
         proceeds in excess of $1,000,000, the proceeds in respect of such loss
         or damage shall be payable to the Agent and (B) the entire amount of
         any loss or damage involving proceeds in the aggregate of $1,000,000 or
         less shall be paid to the Company or its order unless an Event of
         Default or Potential Event of Default then exists and the insurers have
         been notified thereof by the Agent (in which case such payment shall be
         made to the Agent);

                  (iii)    provide that if such insurance is canceled for any
         reason or any substantial change is made in the policies which
         adversely affects the coverage required herein, or if such insurance is
         allowed to lapse for nonpayment of premium, such cancellation, change
         or lapse shall not be effective as to any such Additional Insured or
         the Loss Payee for 30 days (except in the case of war-risk coverage in
         which event the applicable period shall be seven days or such other
         period as may be customary) after receipt by each such Additional
         Insured or the Loss Payee of written notice from such insurer of such
         cancellation, change or lapse;

                  (iv)     provide that, in respect of the interest of any such
         Additional Insured or the Loss Payee in such policies the insurance
         shall not be invalidated by any action or inaction of the Company, the
         Loss Payee or any additional insured as defined under the policy of
         insurance required by this Section 2.04(b) (other than any action or
         inaction of the Loss Payee or such Additional Insured, as the case may
         be) and shall insure the Additional Insured and the Loss Payee
         regardless of any breach or violation of any warranty, declaration or
         condition in such policies by the Company or any other Additional
         Insured as defined under the policy of insurance required under this
         Section 2.04(b);

                  (v)      provide that the insurers shall waive any rights of
         subrogation against the Loss Payee and such Additional Insureds except
         to the extent that any insured event arises solely from the gross
         negligence or willful misconduct of such Additional Insured as
         determined by a final judgement of a court of competent jurisdiction;
<PAGE>
                  (vi)     provide that such insurer shall waive any right of
         such insurer to any set-off or counterclaim or any other deduction,
         whether by attachment or otherwise, in respect of any liability of any
         such Additional Insured or Loss Payee;

                  (vii)    be primary and without rights of contribution from
         any other insurance which is carried by any such Additional Insured or
         the Loss Payee with respect to its interest in the Subject Collateral;

                  (viii)   provide that no such Additional Insured or Loss Payee
         shall have any obligation or liability for premiums or other payments,
         if any, in connection with such insurance; and

                  (ix))    the reinsurer shall agree that in the event of any
         valid claim arising under such reinsurance policy the reinsurers shall
         in lieu of payment to the reinsured, its successors in interest and
         assigns will pay to the Persons named as Additional Insureds under the
         original insurance affected by the Company that portion of any loss for
         which the reinsurers would otherwise be liable to pay the reinsured
         (subject to proof of loss) it being understood and agreed that any such
         payment shall fully discharge and release the reinsurer from any and
         all further liability in connection with such claims.

         (c)      Application of Insurance Proceeds.

                  (i)      Except as expressly provided in Section 2.04(c)(ii)
or (iii) below, all insurance proceeds (other than proceeds from policies
carried by the Agent or the Lenders) received under policies described in
Section 2.04(b) will be paid to the Agent except as otherwise provided in
Section 2.04(b)(ii) and paid by the Agent to the Company unless an Event of
Default or Potential Event of Default exists, in which event such proceeds shall
be retained by the Agent. If the Agent retains any such insurance proceeds
pursuant to this Section 2.04(c), such proceeds shall, until applied by the
Agent as provided in this Section 2.04(c)(i), Section 2.04(c)(ii) or Section
2.04(c)(iii) hereof, be maintained by the Agent in a segregated account and
shall, at the Company's request therefor, be invested in Permitted Cash
Equivalents.

                  (ii)     Insurance proceeds in respect of any Repairable
Damage with respect to any Aircraft which is not required by subsection
2.4B(iii)(1) of the Credit Agreement to be excluded from the Borrowing Base
shall be retained by the Agent pending repair thereof, and shall be applied by
the Agent in payment (or to reimburse the Company) for repairs to the affected
Aircraft upon receipt from the Company of an Officer's Certificate annexing
copies of invoices relating to such repairs, provided, however, that the Agent
shall not so apply any such proceeds during the occurrence and continuance of
any Potential Event of Default or Event of Default. Any such insurance proceeds
in excess of the total amount required to pay for repair of the affected
Aircraft shall, upon certification by the Company to the Agent in an Officer's
Certificate that such repair has been completed, be paid by the Agent to the
Company provided, however, that the Agent shall not so pay any such insurance
proceeds during the occurrence and continuance of any Potential Event of Default
or Event of Default.
<PAGE>
                  (iii)    If an Event of Default shall have occurred and be
continuing, the Agent shall apply all insurance proceeds (including proceeds of
any earnings on any Permitted Cash Equivalents in which such insurance proceeds
have been invested) then on deposit with it pursuant to Section 2.04(c)(i) or
Section 2.04(c)(ii) hereof (all such insurance and other proceeds and earnings
being herein collectively called "Section 2.04(c) Proceeds") to payment of the
Obligations then due. At such time as no Potential Event of Default or Event of
Default shall be continuing, any Section 2.04(c) Proceeds remaining on deposit
with the Agent shall be (x) applied as provided in Section 2.04(c)(ii), if then
applicable, or (y) if Section 2.04(c)(ii) is not then applicable, shall be paid
by the Agent to the Company.

                  (iv)     If any of the Lenders or the Agent becomes subject to
any claim covered by any insurance policy maintained pursuant to this Section
2.04, the Company shall make available any information reasonably required by
such Lender or the Agent in connection with such claim.

                  (d)      Reports. On or before the date hereof and thereafter
annually on or before the scheduled expiration date for such policy, the
Company's aviation insurance broker will furnish to the Agent a certificate and
letter of undertaking, signed by the Company's independent aviation insurance
broker, stating the types of coverage and limits carried and maintained on the
Aircraft and certifying that such insurance complies with the terms and
conditions of this Section 2.04. The Company will cause its aviation insurance
broker to advise the Agent in writing promptly of any default in the payment of
any premium and of any other act or omission on the part of the Company in any
such case of which it has knowledge and which is likely to cause cancellation of
all or any part of any insurance carried by the Company with respect to the
Aircraft. The Company will cause such insurance broker to agree to advise the
Agent in writing if and when it becomes evident to such broker that any
insurance policy carried and maintained on the Aircraft pursuant to this Section
2.04 will not be renewed at the expiration date. The Company will also cause
such insurance broker to deliver to the Agent, on or prior to the date of
expiration of any insurance policy referenced in a previously delivered
certificate of insurance, a new certificate of insurance, confirming to such
parties that such insurance as certified on the date thereof continues in full
force and effect. If the Company shall fail to maintain insurance as required
hereby, the Agent may, at its option, provide such insurance, and in such event,
the Company shall, upon demand, reimburse the Agent for the cost of such
insurance; provided, however, that no exercise of said option shall affect the
provisions of this Security Agreement, including the provisions that failure by
the Company to maintain the prescribed insurance shall constitute an Event of
Default, or otherwise constitute a waiver of any other rights the Agent may have
against the Company.

                  (e)      Notice of Proceeds. The Company shall promptly notify
the Agent upon a Responsible Officer of the Company obtaining actual knowledge
thereof of the occurrence of an event of loss or damage to any Aircraft which is
reasonably expected to result in the receipt of insurance proceeds reasonably
estimated by the Company to exceed $1,000,000.

<PAGE>
                  SECTION 2.05. Infection. At reasonable times and upon
reasonable notice, the Agent or its authorized representative may, at their own
expense (unless an Event of Default then exists or a Potential Event of Default
arising under the maintenance requirements of this Security Agreement, in which
case the reasonable expenses of such inspection shall be paid by the Company or
unless subsection 2.10 of the Credit Agreement provides that such inspection
shall be at the expense of the Company), inspect the Aircraft and inspect of the
books and records and FAA-required books and records of the Company in each case
relating to the maintenance of the Aircraft. Any such inspection of the Aircraft
shall be a visual, walk-around inspection (including on-board inspection) and
may include inspection of areas exposed by any open panels, bays or the like,
but shall not include opening any panels, bays or the like without the express
written consent of the Company; provided that no exercise of such inspection
right shall interfere with the normal operation of the Aircraft by, or the
business of, the Company. The Agent shall have no duty to make any such
inspection nor shall it incur any liability or obligation by reason of not
making any such inspection.

                  SECTION 2.06. Further Assurances. (a) The Company agrees from
time to time, at its sole expense, to promptly execute and deliver all further
instruments and documents, and take all further action, that the Agent may
request, in order to perfect and protect any security interest granted or
purported to be granted hereby or to enable the Agent to exercise and enforce
its rights and remedies hereunder with respect to any of the Subject Collateral.
Without limiting the generality of the foregoing, such further actions shall
include executing and delivering such amendments or supplements to the schedules
to this Security Agreement, executing and filing such financing or continuation
statements, or amendments thereto, executing, filing and recording such
documents or instruments with the Federal Aviation Administration, and executing
and filing such other instruments or notices, in each case as the Agent on
behalf of the Lenders may reasonably request, in order to perfect and preserve
the security interest granted or purported to be granted hereby.

                           (b) The Company hereby authorizes the Agent to file
one or more financing or continuation statements or similar instruments or
documents, and amendments thereto, relative to all or any part of the Subject
Collateral without the signature of the Company where permitted by law.

                  SECTION 2.07. Recording and Filing; Opinions of Counsel. The
Company will bear the expense of and be responsible for recording and
re-recording, registering and re-registering and filing and re-filing this
Security Agreement and each and every Security Agreement Supplement and such
other instruments from time to time as may be reasonably requested by the Agent
in all such jurisdictions and offices as the Agent shall from tine to time
require in order that (a) the Lien hereof be and continues to be a first
priority Lien on all of the Subject Collateral to the fullest extent permitted
under applicable law, subject to Permitted Liens, (b) all of the Subject
Collateral is and remains security for the Obligations, and (c) the rights and
remedies of the Agent may be established, confirmed, maintained and protected;
and the Company will furnish to the Agent evidence satisfactory to the Agent of
every such recording, registering and filing which is not filed, recorded or
registered by the Agent. The
<PAGE>
foregoing includes, without limitation, the execution and delivery by the
Company of all documents, financing statements and continuation statements
deemed reasonably necessary by the Agent to perfect the Agent's rights as
secured party. The Company, at its own cost and expense, shall on the date of
this Security Agreement cause this Security Agreement to be duly filed for
recordation with the FAA and shall make such other filings to perfect the Lien
of this Security Agreement against the Subject Collateral as shall be reasonably
requested by the Agent. The Company will furnish to the Agent an opinion of
counsel reasonably satisfactory to the Agent or other evidence reasonably
satisfactory to the Agent to the effect that such filings or refilings and such
recordations or re-recordations have been duly accomplished and as to any Liens
of record against the Aircraft or any Engine in the office where such filings or
refilings or recordations or re-recordations have been accomplished.

                  [SECTION 2.08. Section 1110. TO THE EXTENT PROVIDED THEREBY
(OR TO THE FULLEST EXTENT IT MAY LAWFULLY SO AGREE, WHETHER OR NOT PROVIDED
THEREBY), THE COMPANY HEREBY AGREES THAT ANY RIGHT OF THE AGENT TO TAKE

THIS SECURITY AGREEMENT AND IN ACCORDANCE WITH SECTION 1110 OF TITLE 11 OF THE
UNITED STATES CODE OR ANY SIMILAR PROVISION OF ANY SUPERSEDING STATUTE, AS

STATUTE, AS AMENDED FROM TIME TO TIME, AND ACCORDINGLY, IT IS THE INTENTION OF
THE PARTIES HERETO THAT WITH RESPECT TO THE SECTION 1110 PROPERTY, THIS
SECURITY AGREEMENT BE AFFORDED THE BENEFITS OF SAID SECTION 1110.]**

(a) [SECTION 2.09. First Placed in Service. Schedule I hereto specifically
identifies, to the extent known to the Company with respect to Aircraft not
first placed in service by the Company, if the Aircraft was first placed in
service after October 22, 1994 or was acquired by the Company with the proceeds
of the Credit Agreement ("Section 1110 Property"). Each Security Agreement
Supplement adding a Replacement Engine to be subject to the Lien of this
Security Agreement shall also identify to the extent known to the Company
whether such Engine was first placed in service after October 22, 1994.]**

                  SECTION 2.10. Power of Attorney. The Company hereby
irrevocably appoints the Agent as the Company's attorney-in-fact and agent to
the extent permitted by law, effective on or after the acceleration of the
Loans, but prior to the Agent obtaining physical possession of

the Subject Collateral, in the Company's name and without any action on the part
of the Company to do, at the Agent's option, any act the Agent reasonably
believes necessary to protect the interests of the Agent in the Subject
Collateral. The appointment of the Agent and the rights and powers in connection
therewith, being coupled with an interest and with full power of substitution
and resubstitution for the Company, are and shall remain irrevocable until all
of the Obligations have been fully paid and performed and the Commitments of the
Lenders under the Credit Agreement have expired or been terminated.

                  SECTION 2.11. Indemnification. The Company shall assume
liability for and will indemnify, protect, save, and keep harmless the Agent and
each of the Lenders, and their respective agents, employees, successors and
permitted assigns (collectively, the "Indemnified Parties") from and against any
and all liabilities, losses, damages, taxes, claims, actions, suits, costs,
demands and/or expenses of whatsoever kind, including, without limitation, legal
expenses, imposed on, incurred by, or asserted against the Agent, the Company,
the Subject Collateral (or any part thereof or interest therein), arising out of
the [purchase]***, ownership, delivery, possession, use, operation, condition,
performance, quality, suitability, airworthiness, maintenance, modification,
registration, loss, confiscation, seizure, requisition, or lease of the Aircraft
(collectively, the "Indemnified Events"). Notwithstanding the foregoing, the
Company shall not indemnify an Indemnified Party in respect of (i) any
Indemnified Events suffered or incurred after the release of the Lien of this
Security Agreement pursuant to the terms hereof, (ii) Indemnified Events that
consist of fees, costs or expenses which such Indemnified Party has expressly
agreed to pay in any provision of this Security Agreement or constitute ordinary
and usual operating or overhead expenses of an Indemnified Party (excluding,
without limitation, costs and expenses of any outside counsel, consultant or
agent), (iii) Indemnified Events arising from the gross negligence or willful
misconduct of such Indemnified Party, (iv) any Indemnified Events arising out of
any breach by the Agent of Section 2.12 hereof, (v) any tax arising as a result
of a voluntary transfer of any Indemnified Party's interest pursuant to Section
9.1 of the Credit Agreement provided that no Event of Default exists at the time
of such transfer, (vi) taxes, withholdings, imposts or duties imposed on, based
on or measured by the gross or net income, receipts, maximum tax, profits,
gains, capital, franchise, excess profits or net worth of an Indemnified Party
other than, in each case, resulting from the activities or presence of the
Company in the taxing jurisdiction or the use, location or registration of the
Aircraft (or any part thereof) in such taxing jurisdiction, (vii) taxes on items
of tax preference or any minimum tax imposed by the federal government of the
United States, (viii) interest, penalties, fines or additions to taxes that
would not have been imposed but for any failure to file any tax return or
information return in a timely and proper manner after timely notice by the
Company of such filing requirement and provision by the Company (at the
Company's expense) of all properly completed forms necessary in connection
therewith and (ix) any tax imposed as a result of a connection between an
Indemnified Party and the jurisdiction imposing such taxes, including, without
limitation, engaging or having engaged in business in, having or having had an
office, branch or permanent establishment in, or being or having been a citizen
or resident of, or present

in, or incorporated or created in or under the laws of such jurisdiction other
than as a result of a connection arising from this transaction. Each Indemnified
Party shall file its tax returns and deal with taxing authorities in good faith,
and will honor all reasonable requests from the Company to file, or provide the
Company with, such information (but excluding information such Indemnified Party
considers confidential) as is necessary to complete forms or other documentation
(in each case, prepared by the Company at its sole expense) as shall enable such
Indemnified Party or the Company to claim a reduced rate of tax or exemption
from tax with respect to any taxes subject to payment or indemnification by the
Company hereunder to which it may be entitled. If the Company is or may be
required to make any payment under this Section 2.11, any relevant Indemnified
Party shall, at the reasonable request of the Company, consult with the Company
in good faith to consider what action may be taken to resist payment of the
amount claimed. Each indemnity pursuant to this Section 2.11 shall be in the
amount which, after taking into account all taxes required to be paid by the
Agent as a result of the receipt or accrual of such amount, shall be equal to
the amount of the indemnity then due. The Company's obligations under this
Section 2.11 shall survive the expiration or termination of this Security
Agreement and the release of the Lien hereof from any or all of the Subject
Collateral.

                  SECTION 2.12. Use and Possession. Notwithstanding the terms of
any provision contained in this Security Agreement or the Credit Agreement,
except as provided in Section 3.01(e) of this Security Agreement, the Company
shall have the exclusive right to use and possess the Aircraft, to collect,
retain, use and enjoy all rents and accounts and to exercise its right, title
and interest in contracts, leases, licenses, permits and governmental approvals
subject at all times to (a) the right of the Agent to receive insurance proceeds
pursuant to Section 2.04(c) hereof, (b) the applicable restrictions and
limitations contained in Section 5.4 of the Credit Agreement and (c) such use,
possession, retaining, enjoyment or exercise not otherwise constituting an Event
of Default.

                   ARTICLE III EVENTS OF DEFAULT AND REMEDIES

                  SECTION 3.01. Remedies, Obtaining the Aircraft Upon Default.
The Company agrees that, if the Loans have been accelerated, then, subject to
any mandatory requirements of applicable law then in effect, the Agent, in
addition to any rights now or hereafter existing under applicable law, shall
have all rights as a secured creditor under the UCC in all relevant
jurisdictions and may:

                  (a) to the extent permitted by law, personally, or by agents
         or attorneys, immediately take possession of the Aircraft or any part
         thereof, from the Company with or without notice or process of law, and
         for that purpose may enter upon the Company's premises where all or any
         part of the Aircraft is located and remove the same; and

                  (b) instruct the obligor or obligors on any agreement,
         instrument or other obligation relating to the Aircraft to make any
         payment included in the Subject Collateral required by the terms of
         such instrument or agreement directly to the Agent; and
<PAGE>
                  (c) sell or assign, or direct the Company to sell or assign,
         the Aircraft or any part thereof, and take possession of the proceeds
         of any such sale or assignment; and

                  (d) take possession of the Aircraft or any part thereof, by
         directing the Company in writing to deliver the same to the Agent at
         any place or places designated by the Agent, in which event the Company
         shall at its own expense forthwith fly or cause to be flown all or any
         part of the Aircraft to such airport or airports in the United States
         so designated by the Agent and there delivered to the Agent, and the
         Company shall pay all reasonable and necessary expenses to (i) store
         and keep all or any part of the Aircraft so delivered to the Agent at
         such place or places pending further action by the Agent as provided in
         Section 4.02, and (ii) while all or any part of the Aircraft shall be
         so stored and kept, provide guards and maintenance services as shall be
         necessary to protect the same and to preserve and maintain them in good
         condition; and

                  (e) revoke all or any of the rights of the Company provided
         for pursuant to Section 2.12 of this Security Agreement by written
         notice to the Company indicating which rights are revoked;

it being understood that the Company's obligation so to deliver the Aircraft or
any part thereof is of the essence of this Security Agreement and that,
accordingly, upon application to a court of equity having jurisdiction, the
Agent shall be entitled to a decree requiring specific performance by the
Company of said obligation.

                  SECTION 3.02. Remedies; Disposition of the Aircraft. (a) The
Aircraft, or any part thereof repossessed by the Agent under or pursuant to
Section 4.01, whether or not so repossessed by the Agent, may be sold, assigned,
leased or otherwise disposed of under one or more contracts or as an entirety,
and without the necessity of gathering at the place of sale the property to be
sold, and in general in such manner, at such time or times, at such place or
places and on such terms as the Agent may, in compliance with any mandatory
requirements of applicable law, determine to be commercially reasonable. The
Aircraft or any part thereof may be sold, leased or otherwise disposed of, in
the condition in which the same existed when taken by the Agent or after any
overhaul or repair which the Agent shall determine to be commercially
reasonable. Any such disposition which shall be a private sale or other private
proceedings permitted by such requirements shall be made upon not less than 10
days' written notice to the Company specifying the time at which such
disposition is to be made and the intended sale price or other consideration
therefor. Any such disposition which shall be a public sale permitted by such
requirements shall be made upon not less than 10 days' written notice to the
Company specifying the time and place of such sale. To the extent permitted by
any such requirement of law, the Agent and the Lenders may bid for and become
the purchaser of the Aircraft or any part thereof, offered for sale in
accordance with this Section without accountability to the Company (except to
the extent of surplus money received as provided in Section 3.03) and may bid
the amount of the Obligations to be applied as credits against such purchase.
If, under mandatory requirements of applicable law, the Agent shall be required
to make disposition of the Aircraft or any part thereof within a period of time
which does not permit the giving of notice to the
<PAGE>
Company as hereinabove specified, the Agent need give the Company only such
notice of disposition as shall be required by such mandatory requirements of
applicable law. Any sale of, or the grant of options to purchase, or any other
realization upon, the Aircraft or any part thereof shall operate to divest all
right, title, interest, claim and demand, either at law or in equity, of the
Company therein and thereto, and shall be a perpetual bar both at law and in
equity against the Company and against any and all Persons claiming or
attempting to claim the Aircraft so sold, optioned or realized upon, or any part
thereof, from, through and under the Company but without limitation of the
Company's rights under Section 3.03 third hereof. At the request of the Agent,
the Company shall deliver such instruments of title or other instruments to
ratify or document such sale but such instruments shall not be necessary to make
such sale final or binding.

                  (b) The Company covenants (to the extent that it may lawfully
         do so) that it will not at any time insist upon, or plead, or in any
         manner whatsoever claim or take the benefit or advantage of, any
         appraisement, valuation, stay, extension or redemption law wherever
         enacted, nor at any time hereafter in force in any locality where any
         property subject to the Lien hereof may be situated, in order to
         prevent, hinder or delay the enforcement or foreclosure of this
         Security Agreement or the execution of any power granted herein to the
         Agent, or the absolute sale of the Aircraft, or any part thereof, or
         the final and absolute putting into possession thereof, immediately
         after such sale, by any purchaser at any sale under this Section 3.02
         but without limitation of the Company's rights under Section 3.03 third
         hereof; and the Company, so far as it now or thereafter lawfully may,
         hereby waives the benefit of all such laws. The Company waives, to the
         extent that it lawfully may, all right to have the property in the
         Subject Collateral marshalled upon any foreclosure hereof, and agrees
         that any court having jurisdiction to foreclose this Security Agreement
         may order the sale of the Subject Collateral as an entirety. If the
         Agent seeks to take possession of any or all of the Subject Collateral
         or avail itself of any provisional remedy by court process, the Company
         hereby irrevocably waives (to the extent it may lawfully do so) any
         bonds and any surety or security required by any statute, court rule or
         otherwise as an incident to such possession, or remedy, and waives any
         demand for possession prior to the commencement of any suit or action
         to recover.

                  (c) if the Loans are accelerated, at the request of the Agent,
         the Company shall promptly execute and deliver to the Agent such
         instruments of title and other documents as the Agent may deem
         necessary or advisable to enable the Agent or an agent or
         representative designated by the Agent, at such time or times and place
         or places as the Agent may specify, to obtain possession or control of
         all or any part of the Subject Collateral. To the extent permitted by
         law, if the Company shall for any reason fail to execute and deliver
         such instruments and documents after such request by the Agent, the
         Agent may (x) obtain a judgment conferring on the Agent the right to
         immediate possession and/or control and requiring the Company to
         deliver such instruments of title and other documents as the Agent may
         deem necessary or advisable to enable the Agent or an agent or
         representative designated by the Agent, at such time or times and place
         or places as the Agent may specify, to obtain possession and/or control
         of all or any part of the Subject Collateral, to the entry of which
         judgment the Company hereby specifically consents.
<PAGE>
                  SECTION 3.03. Application of Proceeds. Except as may otherwise
be required by law, any moneys or property actually received by the Agent
pursuant to the exercise of any rights or remedies referred to in Article III
shall (subject to the determination of the Agent as to the incurrence of costs
and expenses appropriate and the use of such moneys and property in connection
with the exercise of such rights or remedies and as to the manner of such
exercise) be applied in the following order:

                  first, to the payment of costs and expenses incurred in the
         enforcement of rights and remedies under this Security Agreement;

                  second, to the payment of all of the Obligations (except for
         such Obligations that shall have been paid pursuant to first item of
         this Section 3.03), ratably according to the then unpaid amounts
         thereof, without preference or priority of any kind among such various
         Obligations; and

                  third, the remainder, if any, to the Company, its successors
         or assigns, to such Person as the Agent may be legally required to be
         paid to or as a court of competent jurisdiction may direct.

                  SECTION 3.04. Remedies Cumulative. Each and every right, power
and remedy hereby specifically given to the Agent shall be in addition to every
other right, power and remedy specifically given under this Security Agreement
or the Credit Agreement and other Loan Documents or now or hereafter existing at
law or in equity, or by statute and each and every right, power and remedy
whether specifically herein given or otherwise existing may be exercised from
time to time or simultaneously and as often and in such order as may be deemed
expedient by the Agent. All such rights, powers and remedies shall be cumulative
and the exercise or the beginning of exercise of one shall not be deemed a
waiver of the right to exercise of any other or others. No delay or omission of
the Agent in the exercise of any such right, power or remedy shall impair any
such right, power or remedy or shall be construed to be a waiver of any Event of
Default or an acquiescence therein.

                  (d) All rights to payment or performance under letters of
         credit including rights to proceeds of letters of credit
         ("Letter-of-Credit Rights"), and all guaranties, endorsements, Liens,
         other contingent obligations or supporting obligations of any Person
         securing or supporting the payment, performance, value or liquidation
         of any of the foregoing (collectively, with Letter-of-Credit Rights,
         referred to hereinafter as "Supporting Obligations"), in each case only
         to the extent that such Supporting Obligations arise from, or are
         related to, the specified accounts receivable set forth on Schedule
         9(a);

                  (e) All books and records relating to any of the foregoing
         (including customer data, credit files, ledgers, computer programs,

         and substitutions for, any of the foregoing, including without
         limitation proceeds of insurance policies insuring any of the
         foregoing.

         All of the property and interests in property described in subsections
(a) through (f) are herein collectively referred to as the "Receivables
Collateral." Notwithstanding the foregoing, "Receivables Collateral" shall not
include any general intangibles or other rights arising under any contracts,
instruments, licenses or other documents as to which the grant of a security
interest would (i) constitute a violation of a valid and enforceable restriction
in favor of a third party on such grant, unless and until any required consents
shall have been obtained or (ii) give any other party to such contract,
instrument, license or other document the right to terminate its obligations
thereunder.

         3.    PERFECTION; CONDITIONS TO GRANT OF SECURITY INTEREST.

                  (a) At the time of execution of this Receivables Security
         Agreement, the Debtor shall have furnished the Secured Party with
         financing statements in form, number and substance suitable for filing,
         and duly authorized by the Debtor, sufficient under applicable law, and
         satisfactory to the Secured Party in order that upon the filing of the
         same and occurrence of the conditions set forth in Section 3(d) hereof
         the Secured Party shall have a duly perfected security interest in all
         Receivables Collateral in which a security interest can be perfected by
         the filing of financing statements;

                  (b) Upon the occurrence of the conditions set forth in Section
         3(d) hereof, to the extent expressly required by the terms hereof, or
         otherwise as the Secured Party may reasonably request, the Debtor shall
         furnish the Secured Party with properly executed issuer acknowledgments
         of the Secured Party's interest in Letter-of-Credit Rights, and
         evidence of the placement of a restrictive legend on tangible chattel
         paper (and the tangible components, if any, of electronic Chattel
         Paper), and take appropriate action reasonably acceptable to the
         Secured Party sufficient to establish the Secured Party's control of
         electronic Chattel Paper (and the electronic components of hybrid
         Chattel Paper), as appropriate, with respect to Receivables Collateral
         in which either (i) a security interest can be perfected only by
         control or such restrictive legending, or (ii) a security interest
         perfected by control or accompanied by such restrictive legending shall
         have priority as against a lien creditor, a purchaser of such
         Receivables Collateral from the Debtor, or a security interest
         perfected by Persons not having control or not accompanied by such
         restrictive legending, in each case in form and substance reasonably
         acceptable to the Secured Party and sufficient under applicable law so
         that the Secured Party shall have a security interest in all such
         Receivables Collateral perfected by control;

                  (c) Upon the occurrence of the conditions set forth in Section
         3(d) hereof, to the extent expressly required by the terms hereof, or
         otherwise as the Secured Party may reasonably request, the Debtor shall
         deliver to the Secured Party or, if the Secured Party shall
         specifically consent in each instance, an agent or bailee of the
         Secured Party, possession of all Receivables Collateral with respect to
         which either a security interest can be perfected only by possession or
         a security interest perfected by possession shall have priority as
         against Persons not having possession, and including in the case of

                                       3
<PAGE>
         Instruments, duly executed endorsements affixed thereto in form and
         substance reasonably acceptable to the Secured Party and sufficient
         under applicable law so that the Secured Party shall have a security
         interest in all such Receivables Collateral perfected by possession;
         subject in each case only to Permitted Liens (as defined in the next
         sentence). Permitted Liens, as used in this Receivables Security
         Agreement, shall mean (i) the Lien of this Receivables Security
         Agreement, (ii) Liens for taxes, assessments or governmental charges
         payable by the Debtor either not delinquent for a period of more than
         thirty (30) days or being contested in good faith by appropriate
         proceedings so long as during such thirty (30) day period there is not
         any material risk of the forfeiture or loss of any Receivables
         Collateral or any interest therein or during such proceeding there is
         not any material risk of the forfeiture or loss of the Receivables
         Collateral or any interest therein due to an effective stay or
         otherwise, (iii) any Lien for the fees or charges of any airport or air
         navigation authority or any materialmen's, repairmen's, landlord's,
         workmen's, supplier's and other like Liens arising in the ordinary
         course of business, for amounts the payment of which is not overdue for
         a period of more than thirty (30) days or is being contested in good
         faith by appropriate proceedings so long as during such thirty (30) day
         period there is not any material risk of the forfeiture or loss of any
         Receivables Collateral or any interest therein or during such
         proceeding there is not any material risk of the forfeiture or loss of
         the Receivables Collateral or any interest therein due to an effective
         stay or otherwise, (iv) Liens which the Secured Party has specifically
         permitted in writing, (v) Liens (other than Liens for taxes) arising
         out of judgments or awards against the Debtor which are being appealed
         so long as during such thirty (30) day period there is not any material
         risk of the forfeiture or loss of any Receivables Collateral or any
         interest therein or during such proceeding there is not any material
         risk of the forfeiture or loss of the Receivables Collateral or any
         interest therein due to an effective stay or otherwise, and (vi) other
         rights of the Debtor and the Secured Party provided in this Receivables
         Security Agreement. All financing statements (including all amendments
         thereto and continuations thereof), control agreements, acknowledgments
         and other documents, electronic identification, restrictive legends,
         and instruments furnished in connection with the creation, enforcement,
         protection, perfection or priority of the Secured Party's security
         interest in Receivables Collateral, including such items as are
         described above in this Section 3, are sometimes referred to herein as
         "Perfection Documents." The delivery of possession of items of or
         evidencing Receivables Collateral, causing other Persons to execute and
         deliver Perfection Documents as appropriate, the filing or recordation
         of Perfection Documents, the establishment of control over items of
         Receivables Collateral, and the taking of such other actions as may be
         necessary or advisable in the determination of the Secured Party to
         create, enforce, protect, perfect, or establish or maintain the
         priority of, the security interest of the Secured Party in the
         Receivables Collateral is sometimes referred to herein as "Perfection
         Action"; and

                  (d) The security interest provided for in this Receivables
         Security Agreement shall be granted effective on the earlier of (i) the
         occurrence of an Event of Default and (ii) a Triggering Event (as
         defined in the next sentence). A Triggering Event shall occur at any
         time when the aggregate amount of Receivables Collateral, as set forth
         on Schedule 9(a) hereto (as such Schedule 9(a) is amended, restated,
         updated and revised from time to time) is $6,000,000 or less.

         4. MAINTENANCE OF SECURITY INTEREST; FURTHER ASSURANCES.

                  (a) The Debtor will from time to time at its own expense,
         deliver specific assignments of Receivables Collateral or such other
         Perfection Documents, and take such other or additional Perfection
         Action, as may be required by the terms of the Loan Documents or as the
         Secured Party may reasonably request in connection with the
         administration or enforcement of this Receivables Security Agreement or
         related to the Receivables Collateral or any part thereof in order to
         carry out the terms of this Receivables Security Agreement, to perfect,
         protect, maintain the priority of or enforce the Secured Party's
         security interest in the Receivables Collateral, subject only to
         Permitted Liens, or otherwise to better assure and confirm to the
         Secured Party its rights, powers and remedies. Without limiting the
         foregoing, upon the occurrence and during the continuance of an Event
         of Default, the Debtor hereby irrevocably authorizes the Secured Party
         to file (with, or to the extent permitted by applicable law, without
         the signature of the Debtor appearing thereon) financing statements
         (including amendments thereto and initial financing statements in lieu
         of continuation statements) or other Perfection Documents (including
         copies thereof) showing the Debtor as "debtor" at such time or times
         and in all filing offices as the Secured Party may from time to time
         reasonably determine to be necessary or advisable to perfect or protect
         the rights of the Secured Party, or otherwise to give effect to the
         transactions herein contemplated.

                  (b) With respect to any and all Receivables Collateral, the
         Debtor agrees to do and cause to be done all things reasonably
         necessary to perfect, maintain the priority of and keep in full force
         the security interest granted in favor of the Secured Party, including,
         but not limited to, the prompt payment upon demand therefor by the
         Secured Party of all fees and expenses (including documentary stamp,
         excise or intangibles taxes) incurred in connection with the
         preparation, delivery, or filing of any Perfection Document or the
         taking of any Perfection Action to perfect, protect or enforce a
         security interest in Receivables Collateral in favor of the Secured
         Party, subject only to Permitted Liens. All amounts not so paid when
         due shall constitute additional Secured Obligations and (in addition to
         other rights and remedies resulting from such nonpayment) shall bear
         interest from the date of demand until paid in full at the default rate
         set forth in Section 2.2E of the Term Loan Agreement (the "Default
         Rate").

                  (c) Effective upon the occurrence of the conditions set forth
         in Section 3(d) hereof, the Debtor agrees to maintain among its books
         and records appropriate notations or evidence of, and to make or cause
         to be made appropriate disclosure upon its financial statements of, the
         security interest granted hereunder to the Secured Party.

                  (d) Effective upon the occurrence of the conditions set forth
         in Section 3(d) hereof, the Debtor agrees that, in the event any
         proceeds (other than goods) of Receivables Collateral shall be or
         become commingled with other property not constituting Receivables
         Collateral, then such proceeds may, to the extent permitted by law, be
         identified by application of the lowest intermediate balance rule to
         such commingled property.

                                       5
<PAGE>
                  (e) The Debtor agrees that at all times it will not
         intentionally discriminate to the Secured Party's material detriment
         against the Receivables Collateral in its collection of the Debtor's
         accounts receivable generally.

         5. RECEIPT OF PAYMENT. In the event an Event of Default shall occur and
be continuing and the Debtor (or any of its affiliates, Subsidiaries,
stockholders, directors, officers, employees or agents) shall receive any
proceeds of Receivables Collateral, including without limitation monies, checks,
notes, drafts or any other items of payment, the Debtor shall hold all such
items of payment in trust for the Secured Party, and as the property of the
Secured Party, separate from the funds and other property of the Debtor, and no
later than the fifth Business Day following the receipt thereof, at the election
of the Secured Party, the Debtor shall cause such Receivables Collateral to be
forwarded to the Secured Party for its custody, possession and disposition in
accordance with the terms hereof and of the other Loan Documents.

         6.    PRESERVATION AND PROTECTION OF RECEIVABLES COLLATERAL.

                  (a) The Secured Party shall be under no duty or liability with
         respect to the collection, protection or preservation of the
         Receivables Collateral, or otherwise. The Debtor shall be responsible
         for the safekeeping of its Receivables Collateral, and in no event
         shall the Secured Party have any responsibility for (i) any loss or
         damage thereto or destruction thereof occurring or arising in any
         manner or fashion from any cause, (ii) any diminution in the value
         thereof, or (iii) any act or default of any carrier, warehouseman,
         bailee or forwarding agency thereof or other Person in any way dealing
         with or handling such Receivables Collateral.

                  (b) The Debtor agrees (i) effective upon the occurrence of the
         conditions set forth in Section 3(d) hereof, to pay when due all taxes,
         charges and assessments against the Receivables Collateral in which it
         has any interest, unless being contested in good faith by appropriate
         proceedings diligently conducted and against which adequate reserves
         have been established in accordance with GAAP and evidenced to the
         satisfaction of the Secured Party and provided that all enforcement
         proceedings in the nature of levy or foreclosure are effectively
         stayed, and (ii) to cause to be terminated and released all Liens
         (other than Permitted Liens) on the Receivables Collateral. Upon the
         failure of the Debtor to so pay or contest such taxes, charges, or
         assessments, or cause such Liens to be terminated, the Secured Party at
         its option may pay or contest any of them or amounts relating thereto
         (the Secured Party having the sole right to determine the legality or
         validity and the amount necessary to discharge such taxes, charges,
         Liens or assessments) but shall not have any obligation to make any
         such payment or contest. All sums so disbursed by the Secured Party,
         including reasonable attorneys' fees, court costs, expenses and other
         charges related thereto, shall be payable promptly after demand by the
         Debtor to the Secured Party and shall be additional Secured Obligations
         secured by the Receivables Collateral and the other Loan Documents, and
         any amounts not so paid (in addition to other rights and remedies
         resulting from such nonpayment) shall bear interest from the date of
         demand until paid in full at the Default Rate.

                                       6
<PAGE>
         7. STATUS OF DEBTOR AND RECEIVABLES COLLATERAL GENERALLY. The Debtor
         represents and warrants to, and covenants with, the Secured Party, with
         respect to itself and the Receivables Collateral as to which it has or
         acquires any interest as provided herein, that:

                  (a) It is (or as to Receivables Collateral acquired after the
         date hereof will be upon the acquisition of the same) and, except as
         permitted by the Term Loan Agreement and subsection (b) of this Section
         7, will continue to be, the owner of the Receivables Collateral, free
         and clear of all Liens, other than the security interest hereunder in
         favor of the Secured Party and Permitted Liens, and that it will at its
         own cost and expense defend such Receivables Collateral and any
         products and proceeds thereof against all claims and demands of all
         Persons (other than holders of Permitted Liens) at any time claiming
         the same or any interest therein adverse to the Secured Party. Upon the
         failure of the Debtor to so defend, the Secured Party may do so at its
         option but shall not have any obligation to do so. All sums so
         disbursed by the Secured Party, including reasonable attorneys' fees,
         court costs, expenses and other charges related thereto, shall be
         payable promptly after demand by the Debtor to the Secured Party and
         shall be additional Secured Obligations secured by the Receivables
         Collateral and the other Loan Documents, and any amounts not so paid on
         demand (in addition to other rights and remedies resulting from such
         nonpayment) shall bear interest from the date of demand until paid in
         full at the Default Rate.

                  (b) It shall not (i) sell, assign, transfer, lease, license or
         otherwise dispose of any of, or grant any option with respect to, the
         Receivables Collateral, except that prior to the occurrence and
         continuance of an Event of Default, the Debtor may collect Receivables
         Collateral and use the proceeds thereof in the ordinary course of its
         business, (ii) create or suffer to exist any Lien upon or with respect
         to any of the Receivables Collateral except for the security interests
         created by this Receivables Security Agreement and Permitted Liens, or
         (iii) take any other action in connection with any of the Receivables
         Collateral that would materially impair the value of the interest or
         rights of the Debtor in the Receivables Collateral taken as a whole or
         that would materially impair the interest or rights of the Secured
         Party.

                  (c) It has full power, legal right and lawful authority to
         enter into this Receivables Security Agreement and to perform its
         terms, including the grant of the security interests in the Receivables
         Collateral herein provided for.

                  (d) No authorization, consent, approval or other action by,
         and no notice to or filing with, any Governmental Authority or any
         other Person is required either (i) for the grant by the Debtor of the
         security interests granted hereby or for the execution, delivery or
         performance of this Receivables Security Agreement by the Debtor, or
         (ii) for the perfection of or the exercise by the Secured Party, of its
         rights and remedies hereunder, except for any action required by the
         UCC to perfect the security interest conferred hereunder.

                  (e) No effective financing statement or other Perfection
         Document similar in effect, nor any other Perfection Action, covering
         all or any part of the Receivables Collateral purported to be granted
         or taken by or on behalf of the Debtor (or by or on

                                       7
<PAGE>
         behalf of any other Person and which remains effective as against all
         or any part of the Receivables Collateral) has been filed in any
         recording office, delivered to another Person for filing (whether upon
         the occurrence of a contingency or otherwise), or otherwise taken, as
         the case may be.

                  (f) (i) The exact legal name of the Debtor as it appears in
         its organizational documents as of the date hereof and at any time
         during the five (5) year period ending as of the date hereof (the
         "Covered Period") is America West Airlines, Inc., (ii) the Debtor is a
         corporation organized and existing under the laws of the State of
         Delaware, (iii) the address of the chief executive office of the Debtor
         as of the date hereof and at any time during the Covered Period is 111
         West Rio Salado Parkway, Tempe, Arizona, 85281, (iv) there are no trade
         names or trade styles used by the Debtor as of the date hereof and at
         any time during the Covered Period other than "America West". The
         Debtor shall not change its name, change its jurisdiction of formation
         (whether by reincorporation, merger or otherwise), change the location
         of its chief executive office, utilize any additional location where
         tangible personal property constituting Receivables Collateral
         (including Account Records and Account Documents) may be located,
         change or use any additional or different trade name or style, except
         in each case upon giving not less than thirty (30) days' prior written
         notice to the Secured Party and taking or causing to be taken at the
         Debtor's expense all such Perfection Action, including the delivery of
         such Perfection Documents, as may be reasonably requested by the
         Secured Party to perfect or protect, or maintain the perfection and
         priority of, the Lien of the Secured Party in Receivables Collateral
         contemplated hereunder.

         8. INSPECTION. At reasonable times and upon reasonable notice, the
Secured Party or its authorized representative may, at their own expense (unless
an Event of Default then exists, in which case the reasonable expenses of such
inspection shall be paid by the Debtor), inspect the books and records of the
Debtor (and to make extracts or copies from such records), and the premises upon
which any of the Receivables Collateral is located, to discuss the Debtor's
affairs and finances with any Person (other than Persons obligated on any
Accounts ("Account Debtors") and to verify with any Person other than Account
Debtors the amount, quality, quantity, value and condition of, or any other
matter relating to, the Receivables Collateral and, if an Event of Default has
occurred and is continuing, to discuss the Debtor's affairs and finances with
the Debtor's Account Debtors and to verify the amount, quality, value and
condition of, or any other matter relating to, the Receivables Collateral with
such Account Debtors. Any such inspection shall not interfere with the normal
business of the Debtor. The Secured Party shall have no duty to make any such
inspection nor shall it incur any liability or obligation by reason of not
making any such inspection.

         9. SPECIFIC COLLATERAL.

                  (a) ACCOUNTS. With respect to its Accounts whether now
         existing or hereafter created or acquired and wheresoever located, the
         Debtor represents, warrants and covenants to the Secured Party, that:

                           (i) The Debtor shall keep accurate and complete
                  records of its Accounts constituting Receivables Collateral
                  ("Account Records") and quarterly,

<PAGE>

                  together with the Compliance Certificate, the Debtor shall
                  provide the Secured Party with an updated Schedule 9(a) in
                  form and substance reasonably acceptable to the Secured Party
                  describing all such Accounts created or acquired by the Debtor
                  ("Schedule of Accounts"); provided, however, that the Debtor's
                  failure to execute and deliver any such Schedule of Accounts
                  shall not affect or limit the Secured Party's security
                  interest or other rights in and to any Accounts. If
                  requested by the Secured Party, the Debtor shall furnish the

                  has complied with Section 7(f) hereof:

                           (iii) The Accounts constituting Receivables
                  Collateral are genuine, are in all respects what they purport
                  to be, are not evidenced by instrument or document or, if
                  evidenced by an instrument or document, are only evidenced by

                           (iv) The Accounts constituting Receivables Collateral
                  cover bona fide sales, leases, licenses or other dispositions
                  of property usually dealt in by the Debtor, or the rendition
                  by the Debtor of services, to an Account Debtor in the
                  ordinary course of business.

                           (v) The amounts of the face value of any Account
                  shown or reflected on any Schedule of Accounts, invoice
                  statement, or certificate delivered to the Secured Party, are
                  actually owing to the Debtor and are not contingent for any
                  reason; and there are no setoffs, discounts, allowances,
                  claims, counterclaims or disputes of any kind or description
                  in an amount greater than $1,000,000 in the aggregate, or
                  greater than $1,000,000 individually, existing or asserted
                  with respect thereto and the Debtor has not made any agreement
                  with any Account Debtor thereunder for any deduction
                  therefrom, except as may be stated in the Schedule of Accounts
                  and reflected in the calculation of the face value of each

                  any Accounts constituting Receivables Collateral which are
                  reasonably expected to materially impair in any way the
                  validity, collectibility or enforcement of such Accounts that
                  would reasonably be likely, in the aggregate, to be of
                  material economic value, or in the aggregate materially reduce
                  the amount payable thereunder from the amount of the invoice
                  face value shown on any Schedule of Accounts, or on any
                  certificate, contract, invoice or statement delivered to the
                  Secured Party with respect thereto.

                           (ii) Other than in the ordinary course of business
                  and in keeping with reasonable and customary practice, the

         benefit. In addition, the Debtor agrees that in the event notice is
         necessary under applicable law, written notice mailed to the Debtor in
         the manner specified herein ten (10) days prior to the date of public
         sale of any of the Receivables Collateral or prior to the date after
         which any private sale or other disposition of the Receivables
         Collateral will be made shall constitute commercially reasonable notice
         to the Debtor. All notice is hereby waived with respect to any of the
         Receivables Collateral which threatens to decline speedily in value or
         is of a type customarily sold on a recognized market. The Secured Party
         may purchase all or any part of the Receivables Collateral at public
         or, if permitted by law, private sale, free from any right of
         redemption which is hereby expressly waived by the Debtor and, in lieu
         of actual payment of such purchase price, may set off the amount of
         such price against the Secured Obligations.

         The net cash proceeds resulting from the collection, liquidation, sale,
or other disposition of the Receivables Collateral shall be applied first to the
expenses (including all reasonable attorneys' fees) of retaking, holding,
storing, processing and preparing for sale, selling, collecting, liquidating and
the like, and then to the satisfaction of all Secured Obligations in accordance
with the terms of the Term Loan Agreement. The Debtor shall be liable to the
Secured Party and shall pay to the Secured Party on demand any deficiency which
may remain after such sale, disposition, collection or liquidation of the
Receivables Collateral.

         11. ATTORNEY-IN-FACT. The Debtor hereby appoints the Secured Party as
the Debtor's attorney-in-fact for the purposes of carrying out the provisions of
this Receivables Security Agreement and taking any action and executing any
instrument which the Secured Party may deem necessary or advisable to accomplish
the purposes hereof, which appointment is irrevocable and coupled with an
interest; provided, that the Secured Party shall have and may exercise rights
under this power of attorney only upon the occurrence and during the continuance
of an Event of Default. Without limiting the generality of the foregoing, upon
the occurrence

                                       14
<PAGE>
and during the continuance of an Event of Default, the Secured Party shall have
the right and power

                  (a) to ask, demand, collect, sue for, recover, compromise,
         receive and give acquittance and receipts for moneys due and to become
         due under or in respect of any of the Receivables Collateral;

                  (b) to receive, endorse and collect any drafts or other
         instruments, documents and chattel paper in connection with clause (a)
         above;

                  (c) to endorse the Debtor's name on any checks, notes, drafts
         or any other payment relating to or constituting proceeds of the
         Receivables Collateral which comes into the Secured Party's possession
         or the Secured Party's control, and deposit the same to the account of
         the Secured Party on account and for payment of the Secured
         Obligations.

                  (d) to file any claims or take any action or institute any
         proceedings that the Secured Party may deem necessary or desirable for
         the collection of any of the Receivables Collateral or otherwise to
         enforce the rights of the Secured Party with respect to any of the
         Receivables Collateral; and

                  (e) to execute, in connection with any sale or other
         disposition of Receivables Collateral provided for herein, any
         endorsement, assignments, or other instruments of conveyance or
         transfer with respect thereto.

         12. REINSTATEMENT. The granting of a security interest in the
Receivables Collateral and the other provisions hereof shall continue to be
effective or be reinstated, as the case may be, if at any time any payment of
any of the Secured Obligations is rescinded or must be remitted to or must
otherwise be returned by the Secured Party or is repaid by the Secured Party in
whole or in part in good faith settlement of a pending or threatened avoidance
claim, whether upon the insolvency, bankruptcy or reorganization of the Debtor
or otherwise, all as though such payment had not been made. The provisions of
this Section 12 shall survive repayment of all of the Secured Obligations and
the termination or expiration of this Receivables Security Agreement in any
manner.

         13. CERTAIN WAIVERS BY THE DEBTOR. The Debtor waives to the extent
permitted by applicable law (a) any right to require the Secured Party or any
other obligee of the Secured Obligations to (x) proceed against any Person or
entity, (y) proceed against or exhaust any Receivables Collateral or other
collateral for the Secured Obligations, or (z) pursue any other remedy in its
power; (b) any defense arising by reason of any disability or other defense of
any other Person, or by reason of the cessation from any cause whatsoever of the
liability of any other Person or entity, (c) any right of subrogation, (d) any
right to enforce any remedy which the Secured Party or any other obligee of the
Secured Obligations now has or may hereafter have against any other Person and
any benefit of and any right to participate in any collateral or security
whatsoever now or hereafter held by the Secured Party. The Debtor authorizes the
Secured Party and each other obligee of the Secured Obligations without notice
(except notice required by applicable law) or demand and without affecting its
liability hereunder or under the Loan Documents from time to time to: (i) take
and hold security, other than the Receivables

                                       15
<PAGE>
Collateral herein described, for the payment of such Secured Obligations or any
part thereof, and exchange, enforce, waive and release the Receivables
Collateral herein described or any part thereof or any such other security; and
(ii) apply such Receivables Collateral or other security and direct the order or
manner of sale thereof as the Secured Party or such obligee in its discretion
may determine.

         The Secured Party may at any time deliver (without representation,
recourse or warranty) the Receivables Collateral or any part thereof to the
Debtor and the receipt thereof by the Debtor shall be a complete and full
acquittance for the Receivables Collateral so delivered, and the Secured Party
shall thereafter be discharged from any liability or responsibility therefor.

         14. CONTINUED POWERS. Until the Secured Obligations shall have been
irrevocably paid in full, the power of sale and other rights, powers and
remedies granted to the Secured Party hereunder shall continue to exist and may
be exercised by the Secured Party at any time and from time to time irrespective
of the fact that any of the Secured Obligations or any part thereof may have
become barred by any statute of limitations or that any part of the liability of
the Guarantor may have ceased.

         15. OTHER RIGHTS. The rights, powers and remedies given to the Secured
Party by this Receivables Security Agreement shall be in addition to all rights,
powers and remedies given to the Secured Party under any Loan Document or by
virtue of any statute or rule of law. Any forbearance or failure or delay by the
Secured Party in exercising any right, power or remedy hereunder shall not be
deemed to be a waiver of such right, power or remedy, and any single or partial
exercise of any right, power or remedy hereunder shall not preclude the further
exercise thereof; and every right, power and remedy of the Secured Party shall
continue in full force and effect until such right, power or remedy is
specifically waived in accordance with the terms of the Loan Documents.

         16. ANTI-MARSHALING PROVISIONS. The right is hereby given by the Debtor
to the Secured Party to make releases (whether in whole or in part) of all or
any part of the Receivables Collateral agreeable to the Secured Party without
notice to, or the consent, approval or agreement of other parties and interests,
including junior lienors, which releases shall not impair in any manner the
validity of or priority of the Liens and security interests in the remaining
Receivables Collateral conferred hereunder, nor release the Debtor from personal
liability for the Secured Obligations. Notwithstanding the existence of any
other security interest in the Receivables Collateral held by the Secured Party,
the Secured Party shall have the right to determine the order in which any or
all of the Receivables Collateral shall be subjected to the remedies provided in
this Receivables Security Agreement. The Debtor hereby waives any and all right
to require the marshaling of assets in connection with the exercise of any of
the remedies permitted by applicable law or provided herein or in any Loan
Document.

         17. ENTIRE AGREEMENT. This Receivables Security Agreement, together
with the other Loan Documents, constitutes and expresses the entire
understanding between the parties hereto with respect to the subject matter
hereof, and supersedes all prior negotiations, agreements and understandings,
inducements, commitments or conditions, express or implied, oral or written,
except as contained in the Loan Documents. The express terms hereof control and
supersede any course of performance or usage of the trade inconsistent with any
of the terms hereof. Neither

                                       16
<PAGE>
 this Receivables Security Agreement nor any portion or provision hereof may be
 changed, altered, modified, supplemented, discharged, canceled, terminated, or
 amended orally or in any manner other than as provided in the Loan Documents.

         18. THIRD PARTY RELIANCE. The Debtor hereby consents and agrees that
all issuers of or obligors in respect of any Receivables Collateral, and all
securities intermediaries, warehousemen, bailees, public officials and other
Persons having any interest in, possession of, control over or right, privilege,
duty or discretion in respect of, any Receivables Collateral shall be entitled
to accept the provisions hereof as conclusive evidence of the right of the
Secured Party to exercise its rights hereunder with respect to the Receivables
Collateral, notwithstanding any other notice or direction to the contrary
heretofore or hereafter given by the Debtor or any other Person to any of such
Persons.

         19. BINDING AGREEMENT; ASSIGNMENT. This Receivables Security Agreement,
and the terms, covenants and conditions hereof, shall be binding upon and inure
to the benefit of the parties hereto, and to their respective successors and
assigns, except that the Debtor shall not be permitted to assign this
Receivables Security Agreement or any interest herein or, except as expressly
permitted herein, in the Receivables Collateral or any part thereof, or
otherwise, except as expressly permitted herein, pledge, encumber or grant any
option with respect to the Receivables Collateral or any part thereof. All
references herein to the Secured Party shall include any successor thereof or
permitted assignee, and any other obligees from time to time of the Secured
Obligations.

         20. AGENT. As provided in Section 8 of the Term Loan Agreement, each
Lender has appointed The Industrial Bank of Japan, Limited, as its Agent for
purposes of this Receivables Security Agreement. In such capacity, The
Industrial Bank of Japan, Limited, shall be entitled to all of the rights and
benefits accorded the Agent by Section 8 of the Term Loan Agreement. Following
the payment in full of all Secured Obligations and the termination or expiration
of the Loan Documents, the provisions of Section 8 of the Term Loan Agreement
shall be deemed to continue in full force and effect for the benefit of the
Agent under this Receivables Security Agreement. For the avoidance of doubt,
nothing in this Section 20 is intended to create any liability or obligation on
the Debtor.

         21. SEVERABILITY. The provisions of this Receivables Security Agreement
are independent of and separable from each other. If any provision hereof shall
for any reason be held invalid or unenforceable, such invalidity or
unenforceability shall not affect the validity or enforceability of any other
provision hereof, but this Receivables Security Agreement shall be construed as
if such invalid or unenforceable provision had never been contained herein.

         22. COUNTERPARTS. This Receivables Security Agreement may be executed
in any number of counterparts each of which when so executed and delivered shall
be deemed an original, and it shall not be necessary in making proof of this
Receivables Security Agreement to produce or account for more than one such
counterpart executed by the Debtor against whom enforcement is sought.

         23. TERMINATION. Subject to the provisions of Section 12, this
Receivables Security Agreement and all obligations of the Debtor hereunder
(excluding those obligations and

                                       17
<PAGE>
liabilities that expressly survive such termination) shall terminate without
delivery of any instrument or performance of any act by any party upon
irrevocable payment and performance, in full, of the obligations of the Debtor
provided for in the Loan Documents. Upon such termination of this Receivables
Security Agreement, the Secured Party shall, at the request and sole expense of
the Debtor, promptly deliver to the Debtor such termination statements and take
such further actions as the Debtor may reasonably request to terminate of
record, or otherwise to give appropriate notice of the termination of, any Lien
conferred hereunder.

         24. INDEMNIFICATION. Without limitation of any other indemnification
provision in any Loan Document, the Debtor agrees to indemnify and hold harmless
the Secured Party and each of his attorneys, agents and advisors (each, an
"Indemnified Party"), from and against any and all claims, damages, losses,
liabilities, costs, and expenses (including, without limitation, reasonable
attorneys' fees) that may be incurred by or asserted or awarded against any
Indemnified Party, in each case arising out of or in connection with or by
reason of (including, without limitation, in connection with any investigation,
litigation or proceeding or preparation of defense in connection therewith) the
Loan Documents, any of the transactions contemplated herein or the actual or
proposed use of the proceeds of the advances or other extension of credit under
the Loan Documents, except to the extent such claim, damage, loss, liability,
cost, or expense is found in a final, non-appealable judgment by a court of
competent jurisdiction to have resulted from such Indemnified Party's gross
negligence or willful misconduct. In the case of an investigation, litigation or
other proceeding to which the indemnity in this Section 24 applies, such
indemnity shall be effective whether or not such investigation, litigation or
proceeding is brought by the Debtor, any of its directors, shareholders or
creditors, or an Indemnified Party or any other Person, or any Indemnified Party
is otherwise a party thereto and whether or not the transactions contemplated
hereby are consummated. The Debtor agrees that no Indemnified Party shall have
any liability (whether direct or indirect, in contract or tort or otherwise) to
it, any of its subsidiaries or affiliates, or any security holders or creditors
thereof arising out of, related to or in connection with the transactions
contemplated herein or in the other Loan Documents, except to the extent that
such liability is found in a final non-appealable judgment by a court of
competent jurisdiction to have directly resulted from such Indemnified Party's
gross negligence or willful misconduct. The Debtor agrees not to assert any
claim against the Secured Party, any of his attorneys, agents or advisers, on
any theory of liability, for special, indirect, consequential, or punitive
damages arising out of or otherwise relating to the Loan Documents, any of the
transactions contemplated therein or the actual or proposed use of the proceeds
of the Loans or other extensions of credit under the Loan Documents. The
agreements in this Section 24 shall survive repayment of all of the Secured
Obligations and the termination or expiration of this Receivables Security
Agreement in any manner.

         25. NOTICES. Any notice required or permitted hereunder shall be given
in accordance with Section 9.8 of the Term Loan Agreement.

         26. RULES OF INTERPRETATION. The rules of interpretation
contained in Section 1 of the Term Loan Agreement shall be applicable to this
Receivables Security Agreement and are hereby incorporated by reference. All
representations and warranties contained herein shall survive the delivery of
documents and any extension of credit referred to herein or secured hereby.

                                       18
<PAGE>
         27. WAIVER. To the extent permitted by applicable law, no failure on
the part of the Agent or any Lender to exercise and no delay in exercising, and
no course of dealing with respect to, any right, remedy, power or privilege
under this Receivables Security Agreement shall operate as a waiver of such
right, remedy, power or privilege, nor shall any single or partial exercise of
any right, remedy, power or privilege under this Receivables Security Agreement
preclude any other or further exercise of any such right, remedy, power or
privilege or the exercise of any other right, remedy, power or privilege. The
rights, remedies, powers and privileges provided in this Receivables Security
Agreement are cumulative and not exclusive of any rights, remedies, powers and
privileges provided by law.

         28. GOVERNING LAW. THIS RECEIVABLES SECURITY AGREEMENT SHALL BE
DELIVERED IN THE STATE OF NEW YORK AND GOVERNED BY, AND CONSTRUED AND ENFORCED
IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK.

                                FORM OF TERM NOTE

$[              ]                                               January  , 2002

         in the Term Loan Agreement (as hereinafter defined) and prior to or on
         the Termination Date (as defined in the Term Loan Agreement) the
         principal amount of [$          ] maintained by the Lender pursuant to
         the Amended and Restated Term Loan Agreement dated as of January  ,
         2002 (as amended and in effect from time to time, the "Term Loan
         Agreement"), among the Company, the Lender, the Agent and the other

                  (b) interest on the principal balance hereof from time to time
         outstanding from the Closing Date (as defined in the Term Loan

herein shall have the same meanings herein as in the Term Loan Agreement. This
Note evidences the Loan maintained under, and has been issued by the Company in
accordance with, the terms of the Term Loan Agreement, and is issued in
substitution for and replacement of the Revolving Note dated December 10, 1999

         No delay or omission on the part of the Lender or any holder hereof in
exercising any right hereunder shall operate as a waiver of such right or of any
other rights of the Lender or such holder, nor shall any delay, omission or
waiver on any one occasion be deemed a bar or waiver of the same or any other
right on any further occasion.

         The Company and every endorser and guarantor of this Note or the
obligation represented hereby waives to the full extent permitted by law,
presentment, demand, notice, protest and all other demands and notices in
connection with the delivery, acceptance, performance, default or enforcement of

release of any other party or person primarily or secondarily liable.

         that such interest shall be capitalized as the principal of this PIK
         Note from month to month as further set out in the Schedule hereto and
         paid in kind until this PIK Note is due and payable; and

                  (b) on December 31, 2004, the aggregate principal amount owed
         under this PIK Note is due and payable, and

                  (c) interest on the principal balance hereof from time to time

herein shall have the same meanings herein as in the Term Loan Agreement. This
PIK Note evidences the Company's payment in kind of interest on the Loan

principal amount of this PIK Note and all of the unpaid interest accrued thereon
may become or be declared due and payable in the manner and with the effect
provided in the Term Loan Agreement; provided, that, after such acceleration
interest shall no longer be paid in kind under this PIK Note but shall be
payable when accrued and shall continue to accrue on the outstanding principal
amount of the Lender's Loan and this PIK Note and on all such unpaid and accrued
interest at a rate per annum equal to the default rate set forth in Section 2.2E
of the Term Loan Agreement (4% per annum).

         No delay or omission on the part of the Lender or any holder hereof in
exercising any right hereunder shall operate as a waiver of such right or of any
other rights of the Lender or such holder, nor shall any delay, omission or
waiver on any one occasion be deemed a bar or waiver of the same or any other
right on any further occasion.

         The Company and every endorser and guarantor of this PIK Note or the
obligation represented hereby waives to the full extent permitted by law,
presentment, demand, notice, protest and all other demands and notices in
connection with the delivery, acceptance, performance, default or enforcement of

                         Financial Condition Certificate

         I, _________________________________, hereby certify that I am the
__________________________________ of America West Airlines, Inc., a Delaware
corporation (the "Company"), that I am familiar with its properties, businesses,
assets, finances and operations and that I am duly authorized to execute this
certificate on behalf of the Company, which is being delivered pursuant to

January   , 2002 (the "Credit Agreement") among the Lenders named therein (the
"Lenders") and The Industrial Bank of Japan, as Agent for the Lenders (the
"Agent"). Terms defined in the Credit Agreement are used herein as therein
defined unless otherwise defined herein.

         For purposes of this certificate, the terms below shall have the
following definitions:

                  (a)      "present fair saleable value"
                           The amount that could be obtained by an independent
                           willing seller from an independent willing buyer if
                           the assets of the Company and its Subsidiaries taken
                           as a whole are sold with reasonable promptness in an
                           arm's-length transaction under present conditions for
                           the sale of comparable business enterprises.

                  (b)      "contingent liabilities"
                           The maximum estimated amount of liabilities
                           reasonably likely to result from pending litigation,
                           asserted claims and assessments, guaranties,
                           uninsured risks and other contingent liabilities of
                           the Company and its Subsidiaries taken as a whole
                           after giving effect to the borrowing under the Credit
                           Agreement.

                  (c)      "would constitute an unreasonably small capital"
                           As of the date hereof, the Company and its
                           Subsidiaries taken as a whole is a going concern and
                           has sufficient capital to ensure that it will
                           continue to be a going concern in the business in
                           which it is engaged and proposes to be engaged.

                  I further certify that I have reviewed the Loan Documents and
the contents of this certificate and, in connection therewith, have made such
investigation and inquiries as I deem necessary and appropriate therefor.

                  I hereby further certify that:

                  1. On the date hereof, after giving effect to the transactions
contemplated by the Credit Agreement, the Government Guaranteed Loan and the
other Loan Documents, the

<PAGE>
present fair saleable value of any and all property of the Company and its
Subsidiaries taken as a whole is greater than the total amount of liabilities,
including contingent liabilities, of the Company and its Subsidiaries taken as a
whole.

                  2. On the date hereof, after giving effect to the transactions
contemplated by the Credit Agreement, the Government Guaranteed Loan and the
other Loan Documents, the present fair saleable value of the assets of the
Company and its Subsidiaries taken as a whole exceeds the amount that will be
required to pay the probable liability of the Company and its Subsidiaries taken
as a whole on its existing debts as they become absolute and matured considering
all financing alternatives and potential asset sales reasonably available to the
Company.

                  3. The Company and its Subsidiaries do not intend to or
believe that they will incur debts and liabilities that will be beyond their
ability to pay as such debts and liabilities mature.

                  4. On the date hereof, after giving effect to the transactions
contemplated by the Credit Agreement, the Government Guaranteed Loan and the
other Loan Documents, the Company and its Subsidiaries are not engaged in a
transaction, and are not about to engage in business or a transaction, for which
their property would constitute an unreasonably small capital.

                  5. The Company and its Subsidiaries taken as a whole is
solvent within the meaning given that term and similar terms under applicable
laws relating to fraudulent transfers and conveyances.

                  This certificate is being delivered solely to satisfy the
Company's obligations pursuant to Section 3.C of the Credit Agreement and in my
capacity as          of the Company (and not in my personal capacity). All
statements made herein are to the best of my knowledge after making such
inquiries and analyses as I have deemed necessary or appropriate for the
opinions herein stated.

                  IN WITNESS WHEREOF, the undersigned has executed this
certificate on behalf of the Company this      day of January, 2002.
