up or down to the nearest number (with a rounding-up if there is no nearest
number).

      1.05 TIMES OF DAY. Unless otherwise specified, all references herein to
times of day shall be references to Pacific time (daylight or standard, as
applicable).

                                   ARTICLE II.
                      THE COMMITMENTS AND CREDIT EXTENSIONS

      2.01 LOANS. Subject to the terms and conditions and relying upon the
representations and warranties set forth herein, each Lender, severally and not
jointly, agrees to make loans (each such loan, a "Loan") to Borrower from time
to time, on any Business Day during the Availability Period, in an aggregate
amount not to exceed at any time outstanding the amount of such Lender's
Commitment; provided, however, that after giving effect to any Borrowing, (i)
the Outstanding Amount shall not exceed the Aggregate Commitments, (ii) the
Outstanding Amount of the Loans of any Lender shall not exceed such Lender's
Commitment, and (iii) the Outstanding Amount shall not exceed the Borrowing
Base. Within the limits of each Lender's Commitment, and subject to the other
terms and conditions hereof, Borrower may borrow under this Section 2.01, prepay
under Section 2.03, and reborrow under this Section 2.01. Loans may be Base Rate
Loans or Eurodollar Rate Loans, as further provided herein.

      2.02 BORROWINGS, CONVERSIONS AND CONTINUATIONS OF LOANS.

      (a) Each Borrowing, each conversion of Loans from one Type to the other,
and each continuation of Eurodollar Rate Loans shall be made upon Borrower's
irrevocable notice to Agent, which may be given by telephone. Each such notice
must be received by Agent not later than 11:00 a.m. (i) three Business Days
prior to the requested date of any Borrowing of, conversion to or continuation
of Eurodollar Rate Loans or of any conversion of Eurodollar Rate Loans to Base
Rate Loans, and (ii) on the requested date of any Borrowing of Base Rate Loans.
Each telephonic notice by Borrower pursuant to this Section 2.02(a) must be
confirmed promptly by delivery to Agent of a written Loan Notice, appropriately
completed and signed by a Responsible Officer of Borrower. Each Borrowing of,
conversion to or continuation of Eurodollar Rate Loans shall be in a principal
amount of $5,000,000 or a whole multiple of $1,000,000 in excess thereof. Each
Borrowing of or conversion to Base Rate Loans shall be in a principal amount of
$1,000,000 or a whole multiple of $500,000 in excess thereof. Each Loan Notice
(whether telephonic or written) shall specify (i) whether Borrower is requesting
a Borrowing, a conversion of Loans from one Type to the other, or a continuation
of Eurodollar Rate Loans, (ii) the requested date of the Borrowing, conversion
or continuation, as the case may be (which shall be a Business Day), (iii) the
principal amount of Loans to be borrowed, converted or continued, (iv) the Type
of Loans to be borrowed or to which existing Loans are to be converted, and (v)
if applicable, the duration of the Interest Period with respect thereto. If
Borrower fails to specify a Type of Loan in a Loan Notice or if Borrower fails
to give a timely notice requesting a conversion or continuation, then the
applicable Loans shall be made as, or converted to, Base Rate Loans. Any such
automatic conversion to Base Rate Loans shall be effective as of the last day of
the Interest Period then in effect with respect to the applicable Eurodollar
Rate Loans. If Borrower requests a Borrowing of, conversion to, or continuation
of Eurodollar Rate Loans in any such Loan Notice, but fails to specify an
Interest Period, it will be deemed to have specified an Interest Period of one
month.

                                       23
<PAGE>

      (b) Each Loan Notice submitted by Borrower shall be deemed to be a
representation and warranty that (i) since the Closing Date no event or
circumstance has had or could be reasonably expected to have, either
individually or in the aggregate, a Material Adverse Effect; (ii) no Default or
Collateral Shortfall exists or will exist upon giving effect to the requested
Borrowing, conversion or continuation, and (iii) the conditions specified in
Section 4.02(a) have been satisfied, on and as of the date of the applicable
Borrowing, conversion of Loans from one Type to the other, or continuation of
Eurodollar Rate Loans.

      (c) Following receipt of a Loan Notice, Agent shall promptly notify each
Lender of the amount of its Applicable Percentage of the applicable Loans, and
if no timely notice of a conversion or continuation is provided by Borrower,
Agent shall notify each Lender of the details of any automatic conversion to
Base Rate Loans described in the preceding subsection. In the case of a
Borrowing, each Lender shall make the amount of its Loan available to Agent in
immediately available funds at Administrative Agent's Office not later than 1:00
p.m. on the Business Day specified in the applicable Loan Notice. Upon
satisfaction of the applicable conditions set forth in Section 4.02 (and, if
such Borrowing is the initial Borrowing, Section 4.01), Agent shall make all
funds so received available to Borrower in like funds as received by Agent
either by (i) crediting the account of Borrower on the books of Bank of America
with the amount of such funds or (ii) wire transfer of such funds, in each case
in accordance with instructions provided to (and reasonably acceptable to) Agent
by Borrower.

      (d) Except as otherwise provided herein, a Eurodollar Rate Loan may be
continued or converted only on the last day of an Interest Period for such
Eurodollar Rate Loan. During the existence of a Default, no Loans may be
requested as, converted to or continued as Eurodollar Rate Loans without the
consent of the Required Lenders. During the existence of an Event of Default, if
Agent declares all amounts owing under this Agreement to be immediately due and
payable pursuant to Section 8.02, then the Required Lenders may also demand that
any or all of the then outstanding Eurodollar Rate Loans be converted
immediately to Base Rate Loans and Borrower agrees to pay all amounts due under
Section 3.05 in accordance with the terms thereof due to any such conversion.

      (e) Agent shall promptly notify Borrower and Lenders of the interest rate
applicable to any Interest Period for Eurodollar Rate Loans upon determination
of such interest rate. At any time that Base Rate Loans are outstanding, the
Administrative Agent shall notify the Borrower and the Lenders of any change in
Bank of America's prime rate used in determining the Base Rate promptly
following the public announcement of such change.

      (f) After giving effect to all Borrowings, all conversions of Loans from
one Type to the other, and all continuations of Loans as the same Type, there
shall not be more than 5 Interest Periods in effect at any one time with respect
to Loans.

      2.03 PREPAYMENTS.

      (a) Borrower may, upon notice to Agent, at any time or from time to time
voluntarily prepay Loans in whole or in part without premium or penalty;
provided that (i) such notice must be received by Agent not later than 11:00
a.m. (A) three Business Days prior to any date of prepayment of Eurodollar Rate
Loans and (B) on the date of prepayment of Base Rate Loans;

                                       24
<PAGE>

(ii) any prepayment of Eurodollar Rate Loans shall be in a principal amount of
$5,000,000 or a whole multiple of $1,000,000 in excess thereof; and (iii) any
prepayment of Base Rate Loans shall be in a principal amount of $1,000,000 or a
whole multiple of $500,000 in excess thereof or, in each case, if less, the
entire principal amount thereof then outstanding. Each such notice shall specify
the date and amount of such prepayment and the Type(s) of Loans to be prepaid.
Agent will promptly notify each Lender of its receipt of each such notice, and
of the amount of such Lender's Applicable Percentage of such prepayment. If such
notice is given by Borrower, Borrower shall make such prepayment and the payment
amount specified in such notice shall be due and payable on the date specified
therein. Any prepayment of a Eurodollar Rate Loan shall be accompanied by all
accrued interest on the amount prepaid, together with any additional amounts
required pursuant to Section 3.05. Each such prepayment shall be applied to the
Loans of Lenders in accordance with their respective Applicable Percentages.

      (b) If for any reason the Outstanding Amount at any time exceeds the
Aggregate Commitments then in effect, Borrower shall immediately prepay Loans in
an aggregate amount equal to such excess. If for any reason the Outstanding
Amount at any time exceeds the Borrowing Base (an "Over Advance") then in
effect, Borrower shall either: (i) immediately prepay Loans in an aggregate
amount equal to such Over Advance or (ii) cure such Over Advance by pledging
additional Collateral in accordance with Section 6.15(b) within five Business
Days.

      2.04 TERMINATION OR REDUCTION OF COMMITMENTS. Borrower may, upon notice to
Agent, terminate the Aggregate Commitments, or from time to time permanently
reduce the Aggregate Commitments; provided that (i) any such notice shall be
received by Agent not later than 11:00 a.m. five Business Days prior to the date
of termination or reduction, (ii) any such partial reduction shall be in an
aggregate amount of $5,000,000 or any whole multiple of $1,000,000 in excess
thereof, and (iii) Borrower shall not terminate or reduce the Aggregate
Commitments if, after giving effect thereto and to any concurrent prepayments
hereunder, the Outstanding Amount would exceed the Aggregate Commitments. Agent
will promptly notify the Lenders of any such notice of termination or reduction
of the Aggregate Commitments. Any reduction of the Aggregate Commitments shall
be applied to the Commitment of each Lender according to its Applicable
Percentage. All fees accrued until the effective date of any termination of the
Aggregate Commitments shall be paid on the effective date of such termination.

      2.05 REPAYMENT OF LOANS. Borrower shall repay to Lenders on the Maturity
Date the aggregate principal amount of Loans outstanding on such date.

      2.06 INTEREST.

      (a) Subject to the provisions of subsection (b) below, (i) each Eurodollar
Rate Loan shall bear interest on the outstanding principal amount thereof for
each Interest Period at a rate per annum equal to the Eurodollar Rate for such
Interest Period plus the Applicable Rate; and (ii) each Base Rate Loan shall
bear interest on the outstanding principal amount thereof from the applicable
borrowing date at a rate per annum equal to the Base Rate plus the Applicable
Rate.

                                       25
<PAGE>

      (b)   (i) If any amount of principal of any Loan is not paid when due
(without regard to any applicable grace periods), whether at stated maturity, by
acceleration or otherwise, such amount shall thereafter bear interest at a
fluctuating interest rate per annum at all times equal to the Default Rate to
the fullest extent permitted by applicable Laws.

            (ii) If any amount (other than principal of any Loan) payable by
      Borrower under any Loan Document is not paid when due (without regard to
      any applicable grace periods), whether at stated maturity, by acceleration
      or otherwise, then upon the request of the Required Lenders, such amount
      shall thereafter bear interest at a fluctuating interest rate per annum at
      all times equal to the Default Rate to the fullest extent permitted by
      applicable Laws.

            (iii) Upon the request of the Required Lenders, while any Event of
      Default exists, Borrower shall pay interest on the principal amount of all
      outstanding Obligations hereunder at a fluctuating interest rate per annum
      at all times equal to the Default Rate to the fullest extent permitted by
      applicable Laws.

            (iv) Accrued and unpaid interest on past due amounts (including
      interest on past due interest) shall be due and payable upon demand.

      (c) Interest on each Loan shall be due and payable in arrears on each
Interest Payment Date applicable thereto and at such other times as may be
specified herein. Interest hereunder shall be due and payable in accordance with
the terms hereof before and after judgment, and before and after the
commencement of any proceeding under any Debtor Relief Law.

      2.07 FEES.

      (a) Commitment Fee. Borrower shall pay to Agent for the account of each
Lender in accordance with its Applicable Percentage, a commitment fee equal to
the Applicable Rate times the actual daily amount by which the Aggregate
Commitments exceed the Outstanding Amount. The commitment fee shall accrue at
all times during the Availability Period, including at any time during which one
or more of the conditions in Article IV is not met, and shall be due and payable
quarterly in arrears on the last Business Day of each March, June, September and
December, commencing with the first such date to occur after the Closing Date,
and on the Maturity Date. The commitment fee shall be calculated quarterly in
arrears, and if there is any change in the Applicable Rate during any quarter,
the actual daily amount shall be computed and multiplied by the Applicable Rate
separately for each period during such quarter that such Applicable Rate was in
effect.

      (b) Agent's Fees. Borrower shall pay to Agent for Agent's own account,
fees in the amounts and at the times specified in the letter agreement, dated
November 30, 2004 (the "Agent Fee Letter"), between Borrower and Agent. Such
fees shall be fully earned when paid and shall be nonrefundable for any reason
whatsoever.

      (c) Arrangement and Upfront Fee. Immediately upon the execution and
delivery of this Agreement, Borrower shall pay the arrangement fees and the
upfront fees set forth in, and in

                                       26
<PAGE>

accordance with, the letter agreement, dated November 30, 2004 (the
"Arrangement/Upfront Fee Letter"), among Borrower, the Joint Lead Arrangers and
certain Lenders. Such fees shall be fully earned when paid and shall be
nonrefundable for any reason whatsoever. The upfront fee shall be in an amount
equal to: (i) for each Lender having a Commitment of [***] or less, [***] basis
points times such Lender's Commitment, and (ii) for each Lender having a
Commitment of more than [***], [***] basis points times such Lender's
Commitment.

      2.08 COMPUTATION OF INTEREST AND FEES. All computations of interest for
Base Rate Loans when the Base Rate is determined by Bank of America's "prime
rate" shall be made on the basis of a year of 365 or 366 days, as the case may
be, and actual days elapsed. All other computations of fees and interest shall
be made on the basis of a 360-day year and actual days elapsed (which results in
more fees or interest, as applicable, being paid than if computed on the basis
of a 365-day year). Interest shall accrue on each Loan for the day on which the
Loan is made, and shall not accrue on a Loan, or any portion thereof, for the
day on which the Loan or such portion is paid, provided that any Loan that is
repaid on the same day on which it is made shall, subject to Section 2.10(a),
bear interest for one day. Each determination by Agent of an interest rate or
fee hereunder shall be conclusive and binding for all purposes, absent manifest
error.

      2.09 EVIDENCE OF DEBT. The Borrowings made by each Lender shall be
evidenced by one or more accounts or records maintained by such Lender and by
Agent in the ordinary course of business. The accounts or records maintained by
Agent and each Lender shall be conclusive absent manifest error of the amount of
the Borrowings made by Lenders to Borrower and the interest and payments
thereon. Any failure to so record or any error in doing so shall not, however,
limit or otherwise affect the obligation of Borrower hereunder to pay any amount
owing with respect to the Obligations. In the event of any conflict between the
accounts and records maintained by any Lender and the accounts and records of
Agent in respect of such matters, the accounts and records of Agent shall
control in the absence of manifest error. Upon the request of any Lender made
through Agent, Borrower shall execute and deliver to such Lender (through Agent)
a Note, which shall evidence such Lender's Loans in addition to such accounts or
records. Each Lender may attach schedules to its Note and endorse thereon the
date, Type (if applicable), amount and maturity of its Loans and payments with
respect thereto.

      2.10 PAYMENTS GENERALLY; AGENT'S CLAWBACK.

      (a)   (i) General. All payments to be made by Borrower shall be made
without condition or deduction for any counterclaim, defense, recoupment or
setoff. Except as otherwise expressly provided herein, all payments by Borrower
hereunder shall be made to Agent, for the account of the respective Lenders to
which such payment is owed, at the Administrative Agent's Office in Dollars and
in immediately available funds not later than 12:00 noon on the date specified
herein. Agent will promptly distribute to each Lender its Applicable Percentage
(or other applicable share as provided herein) of such payment in like funds as
received by wire transfer to such Lender's Lending Office. All payments received
by Agent after 12:00 noon shall be deemed received on the next succeeding
Business Day and any applicable interest or fee shall continue to accrue. If any
payment to be made by Borrower shall come due on a day other than a Business
Day, payment shall be made on the next following Business Day, and such
extension of time shall be reflected in computing interest or fees, as the case
may be.

* Indicates that certain information contained herein has been omitted and
  filed separately with the Securities and Exchange Commission. Confidential
  treatment has been requested with respect to the omitted portions.

                                       27
<PAGE>

            (ii) On each date when the payment of any principal, interest or
fees are due hereunder or under any Note, if Agent gives Borrower one Business
Day's prior notice of the amount of such payment, Borrower agrees to maintain on
deposit in an ordinary checking account maintained by Borrower with Agent (as
such account shall be designated by Borrower in a written notice to Agent from
time to time, the "Borrower Account") an amount sufficient to pay such
principal, interest or fees in full on such date. Borrower hereby authorizes
Agent (A) to deduct automatically all principal, interest or fees when due
hereunder or under any Note from the Borrower Account, and (B) if and to the
extent any payment of principal, interest or fees under this Agreement or any
Note is not made when due to deduct any such amount from any or all of the
accounts of Borrower maintained at Agent. Agent agrees to provide written notice
to Borrower of any automatic deduction made pursuant to this Section 2.10(a)(ii)
showing in reasonable detail the amounts of such deduction. Lenders agree to
reimburse Borrower based on their Applicable Percentage for any amounts deducted
from such accounts in excess of amount due hereunder and under any other Loan
Documents.

      (b)   (i) Funding by Lenders; Presumption by Agent. Unless Agent shall
have received notice from a Lender prior to the proposed date of any Borrowing
that such Lender will not make available to Agent such Lender's share of such
Borrowing, Agent may assume that such Lender has made such share available on
such date in accordance with Section 2.02 and may, in reliance upon such
assumption, make available to Borrower a corresponding amount. In such event, if
a Lender has not in fact made its share of the applicable Borrowing available to
Agent, then the applicable Lender and Borrower severally agree to pay to Agent
forthwith on demand such corresponding amount in immediately available funds
with interest thereon, for each day from and including the date such amount is
made available to Borrower to but excluding the date of payment to Agent, at (A)
in the case of a payment to be made by such Lender, the greater of the Federal
Funds Rate and a rate determined by Agent in accordance with banking industry
rules on interbank compensation, plus any administrative, processing or similar
fees customarily charged by Agent in connection with the foregoing and (B) in
the case of a payment to be made by Borrower, the interest rate applicable to
Base Rate Loans. If Borrower and such Lender shall pay such interest to Agent
for the same or an overlapping period, Agent shall promptly remit to Borrower
the amount of such interest paid by Borrower for such period. If such Lender
pays its share of the applicable Borrowing to Agent, then the amount so paid
shall constitute such Lender's Loan included in such Borrowing. Any payment by
Borrower shall be without prejudice to any claim Borrower may have against a
Lender that shall have failed to make such payment to Agent.

            (ii) Payments by Borrower; Presumptions by Agent. Unless Agent shall
have received notice from Borrower prior to the date on which any payment is due
to Agent for the account of the Lenders that Borrower will not make such
payment, Agent may assume that Borrower has made such payment on such date in
accordance herewith and may, in reliance upon such assumption, distribute to
Lenders the amount due. In such event, if Borrower has not in fact made such
payment, then each of Lenders severally agrees to repay to Agent forthwith on
demand the amount so distributed to such Lender, in immediately available funds
with interest thereon, for each day from and including the date such amount is
distributed to it but excluding the date of payment to Agent, at the greater of
the Federal Funds Rate and a rate determined by Agent in accordance with banking
industry rules on interbank compensation. A notice of Agent

                                       28
<PAGE>

to any Lender or Borrower with respect to any amount owing under this subsection
(b) shall be conclusive, absent manifest error.

      (c) Failure to Satisfy Conditions Precedent. If any Lender makes available
to Agent funds for any Loan to be made by such Lender as provided in the
foregoing provisions of this Article II, and such funds are not made available
to Borrower by Agent because the conditions to the applicable Borrowing set
forth in Article IV are not satisfied or waived in accordance with the terms
hereof, Agent shall return such funds (in like funds as received from such
Lender) to such Lender, without interest.

      (d) Obligations of Lenders Several. The obligations of Lenders hereunder
to make Loans and to make payments under Section 10.04(c) are several and not
joint. The failure of any Lender to make any Loan, to fund any such
participation or to make any payment under Section 10.04(c) on any date required
hereunder shall not relieve any other Lender of its corresponding obligation to
do so on such date, and no Lender shall be responsible for the failure of any
other Lender to so make its Loan, purchase its participation or to make its
payment under Section 10.04(c):

      (e) Funding Source. Nothing herein shall be deemed to obligate any Lender
to obtain the funds for any Loan in any particular place or manner or to
constitute a representation by any Lender that it has obtained or will obtain
the funds for any Loan in any particular place or manner.

      2.11 SHARING OF PAYMENTS. If any Lender shall, by exercising any right of
setoff or counterclaim or otherwise, obtain payment in respect of any principal
of or interest on any of the Loans made by it resulting in such Lender's
receiving payment of a proportion of the aggregate amount of such Loans or
participations and accrued interest thereon greater than its pro rata share
thereof as provided herein, then the Lender receiving such greater proportion
shall (a) notify Agent of such fact, and (b) purchase (for cash at face value)
participations in the Loans of the other Lenders, or make such other adjustments
as shall be equitable, so that the benefit of all such payments shall be shared
by the Lenders ratably in accordance with the aggregate amount of principal of
and accrued interest on their respective Loans and other amounts owing them,
provided that:

            (i) if any such participations or subparticipations are purchased
      and all or any portion of the payment giving rise thereto is recovered,
      such participations or subparticipations shall be rescinded and the
      purchase price restored to the extent of such recovery, without interest;
      and

            (ii) the provisions of this Section shall not be construed to apply
      to (x) any payment made by Borrower pursuant to and in accordance with the
      express terms of this Agreement or (y) any payment obtained by a Lender as
      consideration for the assignment of or sale of a participation in any of
      its Loans to any assignee or participant, other than to Borrower or any
      Subsidiary thereof (as to which the provisions of this Section shall
      apply).

                                       29
<PAGE>

      Borrower consents to the foregoing and agrees, to the extent it may
effectively do so under applicable law, that any Lender acquiring a
participation pursuant to the foregoing arrangements may exercise against
Borrower rights of setoff and counterclaim with respect to such participation as
fully as if such Lender were a direct creditor of Borrower in the amount of such
participation.

      2.12 SECURITY. All obligations of Borrower under this Agreement, the Notes
and the other Loan Documents shall be secured in accordance with the Collateral
Documents.

                                  ARTICLE III.
                     TAXES, YIELD PROTECTION AND ILLEGALITY

      3.01 TAXES.

      (a) Payments Free of Taxes. Any and all payments by Borrower to or on
account of any obligation of Borrower hereunder or under any other Loan Document
shall be made free and clear of and without reduction or withholding for any
Indemnified Taxes, provided that if Borrower shall be required by any applicable
law to deduct any Indemnified Taxes from such payments, then, (i) the sum
payable shall be increased as necessary so that after making all required
deductions (including deductions applicable to additional sums payable under
this Section), Agent or Lender, as the case may be, receives an amount equal to
the sum it would have received had no such deductions been made, (ii) Borrower
shall make such deductions, and (iii) Borrower shall timely pay the full amount
deducted to the relevant Governmental Authority in accordance with applicable
law.

      (b) Payment of Other Taxes by Borrower. Without limiting the provisions of
subsection (a) above, Borrower shall timely pay any Other Taxes to the relevant
Governmental Authority in accordance with applicable law.

      (c) Indemnification by Borrower. Borrower shall indemnify Agent and each
Lender, within 30 days after demand therefor, for the full amount of any
Indemnified Taxes (including Indemnified Taxes imposed or asserted on or
attributable to amounts payable under this Section) paid or incurred by Agent or
such Lender, as the case may be, and any penalties, interest and reasonable
expenses arising therefrom or with respect thereto, whether or not such
Indemnified Taxes were correctly or legally imposed or asserted by the relevant
Governmental Authority. A certificate as to the amount of such payment or
liability delivered to Borrower by a Lender (with a copy to Agent), or by Agent
on its own behalf or on behalf of a Lender, shall be conclusive absent manifest
error.

      (d) Evidence of Payments. As soon as practicable after any payment of
Indemnified Taxes by Borrower to a Governmental Authority, Borrower shall
deliver to Agent the original or a certified copy of a receipt issued by such
Governmental Authority evidencing such payment, a copy of the return reporting
such payment or other evidence of such payment reasonably satisfactory to Agent.

      (e) Status of Lenders. Any Foreign Lender that is entitled to an exemption
from or reduction of withholding tax under the law of the jurisdiction in which
the Borrower is resident

                                       30
<PAGE>

for tax purposes, or any treaty to which such jurisdiction is a party, with
respect to payments hereunder or under any other Loan Document shall deliver to
the Borrower (with a copy to the Administrative Agent), at the time or times
prescribed by applicable law or reasonably requested by the Borrower or the
Administrative Agent, such properly completed and executed documentation
prescribed by applicable law as will permit such payments to be made without
withholding or at a reduced rate of withholding. In addition, any Lender, if
requested by the Borrower or the Administrative Agent, shall deliver such other
documentation prescribed by applicable law or reasonably requested by the
Borrower or the Administrative Agent as will enable the Borrower or the
Administrative Agent to determine whether or not such Lender is subject to
backup withholding or information reporting requirements.

Without limiting the generality of the foregoing, in the event that the Borrower
is resident for tax purposes in the United States, any Foreign Lender shall
deliver to the Borrower and the Administrative Agent (in such number of copies
as shall be requested by the recipient) on or prior to the date on which such
Foreign Lender becomes a Lender under this Agreement (and from time to time
thereafter upon the request of the Borrower or the Administrative Agent, but
only if such Foreign Lender is legally entitled to do so), whichever of the
following is applicable:

      (i) duly completed copies of Internal Revenue Service Form W-8BEN claiming
      eligibility for benefits of an income tax treaty to which the United
      States is a party,

      (ii) duly completed copies of Internal Revenue Service Form W-8ECI,

      (iii) in the case of a Foreign Lender claiming the benefits of the
      exemption for portfolio interest under section 881(c) of the Code, (x) a
      certificate to the effect that such Foreign Lender is not (A) a "bank"
      within the meaning of section 881(c)(3)(A) of the Code, (B) a "10 percent
      shareholder" of the Borrower within the meaning of section 881(c)(3)(B) of
      the Code, or (C) a "controlled foreign corporation" described in section
      881(c)(3)(C) of the Code or (D) is otherwise entitled to an exemption from
      U.S. tax under Section 88(c) on the date it acquires its interest herein,
      and (y) duly completed copies of Internal Revenue Service Form W-8BEN, or

      (iv) any other form prescribed by applicable law as a basis for claiming
      exemption from or a reduction in United States Federal withholding tax
      duly completed together with such supplementary documentation as may be
      prescribed by applicable law to permit the Borrower to determine the
      withholding or deduction required to be made.

      (f) Treatment of Certain Refunds. If Agent or any Lender determines, in
its sole discretion, that it has received a refund of any Taxes as to which it
has been indemnified by Borrower or with respect to which Borrower has paid
additional amounts pursuant to this Section, it shall pay to Borrower an amount
equal to such refund (but only to the extent of indemnity payments made, or
additional amounts paid, by Borrower under this Section with respect to the
Taxes giving rise to such refund), net of all out-of-pocket expenses of Agent or
such Lender, as the case may be, and without interest (other than any interest
paid by the relevant Governmental Authority with respect to such refund),
provided that Borrower, upon the request of Agent, such Lender agrees to repay
the amount paid over to Borrower (plus any penalties,

                                       31
<PAGE>

interest or other charges imposed by the relevant Governmental Authority) to
Agent or such Lender in the event Agent or such Lender is required to repay such
refund to such Governmental Authority. This subsection shall not be construed to
require Agent or any Lender to make available its tax returns (or any other
information relating to its taxes that it deems confidential) to the Borrower or
any other Person.

      3.02 ILLEGALITY. If any Lender determines that any Law has made it
unlawful, or that any Governmental Authority has asserted that it is unlawful,
for any Lender or its applicable Lending Office to make, maintain or fund
Eurodollar Rate Loans, or to determine or charge interest rates based upon the
Eurodollar Rate, or any Governmental Authority has imposed material restrictions
on the authority of such Lender to purchase or sell, or to take deposits of,
Dollars in the London interbank market, then, on notice thereof by such Lender
to Borrower through Agent, any obligation of such Lender to make or continue
Eurodollar Rate Loans or to convert Base Rate Loans to Eurodollar Rate Loans
shall be suspended until such Lender notifies Agent and Borrower that the
circumstances giving rise to such determination no longer exist. Upon receipt of
such notice, Borrower shall, upon demand from such Lender (with a copy to
Agent), prepay or, if applicable, convert all Eurodollar Rate Loans of such
Lender to Base Rate Loans, either on the last day of the Interest Period
therefor, if such Lender may lawfully continue to maintain such Eurodollar Rate
Loans to such day, or immediately, if such Lender may not lawfully continue to
maintain such Eurodollar Rate Loans. Upon any such prepayment or conversion,
Borrower shall also pay accrued interest on the amount so prepaid or converted
and all amounts due under Section 3.05 in accordance with the terms thereof due
to such prepayment or conversion.

      3.03 INABILITY TO DETERMINE RATES. If the Required Lenders determine, in
connection with any request for a Eurodollar Rate Loan or a conversion to or
continuation thereof, that (a) Dollar deposits are not being offered to banks in
the London interbank eurodollar market for the applicable amount and Interest
Period of such Eurodollar Rate Loan, (b) adequate and reasonable means do not
exist for determining the Eurodollar Base Rate for any requested Interest Period
with respect to a proposed Eurodollar Rate Loan, or (c) an unusual or
extraordinary event or circumstance occurs or exists affecting the applicable
offshore Dollar market such that the Eurodollar Base Rate for any requested
Interest Period with respect to a proposed Eurodollar Rate Loan does not
adequately and fairly reflect the cost to such Lenders of funding such Loan,
Agent will promptly so notify Borrower and each Lender. Thereafter, the
obligation of Lenders to make or maintain Eurodollar Rate Loans shall be
suspended until Agent (upon the instruction of the Required Lenders) revokes
such notice. Upon receipt of such notice, Borrower may revoke any pending
request for a Borrowing of, conversion to or continuation of Eurodollar Rate
Loans or, failing that, will be deemed to have converted such request into a
request for a Borrowing of Base Rate Loans in the amount specified therein.

      3.04 INCREASED COSTS.

      (a)   Increased Costs Generally. If any Change in Law shall:

            (i) impose, modify or deem applicable any reserve, special deposit,
      compulsory loan, insurance charge or similar requirement against assets
      of, deposits with

                                       32
<PAGE>

      or for the account of, or credit extended or participated in by, any
      Lender (except any reserve requirement reflected in the Eurodollar Rate);
      or

            (ii) impose on any Lender or the London interbank market any other
      condition, cost or expense affecting this Agreement or Eurodollar Loans
      made by such Lender or participation therein;

and the result of any of the foregoing shall be to increase the cost to such
Lender of making or maintaining any Eurodollar Loan (or of maintaining its
obligation to make any such Loan), or to reduce the amount of any sum received
or receivable by such Lender (whether of principal, interest or any other
amount) then, upon request of such Lender, Borrower will pay to such Lender such
additional amount or amounts as will compensate such Lender for such additional
costs incurred or reduction suffered.

      (b) Capital Requirements. If any Lender reasonably determines that any
Change in Law affecting such Lender or any Lending Office of such Lender or such
Lender's holding company, if any, regarding capital requirements has or would
have the effect of reducing the rate of return on such Lender's capital or on
the capital of such Lender's holding company, if any, as a consequence of this
Agreement, the Commitment of such Lender or the Loans made by such Lender to a
level below that which such Lender or such Lender's holding company could have
achieved but for such Change in Law (taking into consideration such Lender's
policies and the policies of such Lender's holding company with respect to
capital adequacy), then from time to time Borrower will pay to such Lender such
additional amount or amounts as will compensate such Lender or such Lender's
holding company for any such reduction suffered.

      (c) Certificates for Reimbursement. A certificate of a Lender setting
forth the amount or amounts necessary to compensate such Lender or its holding
company, as the case may be, as specified in subsection (a) or (b) of this
Section and, in reasonable detail, the basis for such calculation and delivered
to Borrower shall be conclusive absent manifest error. Borrower shall pay such
Lender the amount shown as due on any such certificate within 10 days after
receipt thereof. Such certificate shall also include a statement to the effect
that such compensation for additional costs incurred or reduction suffered
reflects a good faith and non-discriminatory allocation to this Agreement.

      (d) Delay in Requests. Failure or delay on the part of any Lender to
demand compensation pursuant to the foregoing provisions of this Section shall
not constitute a waiver of such Lender's right to demand such compensation,
provided that Borrower shall not be required to compensate a Lender pursuant to
the foregoing provisions of this Section for any increased costs incurred or
reductions suffered more than 30 days prior to the date that such Lender
notifies Borrower of the Change in Law giving rise to such increased costs or
reductions and of such Lender's intention to claim compensation therefor (except
that, if the Change in Law giving rise to such increased costs or reductions is
retroactive, then the 30-day period referred to above shall be extended to
include the period of retroactive effect thereof).

      3.05 COMPENSATION FOR LOSSES. Upon demand of any Lender (with a copy to
Agent) from time to time, Borrower shall promptly compensate such Lender for and
hold such Lender harmless from any loss, cost or expense incurred by it as a
result of:

                                       33
<PAGE>

      (a) any continuation, conversion, payment or prepayment of any Loan other
than a Base Rate Loan on a day other than the last day of the Interest Period
for such Loan (whether voluntary, mandatory, automatic, by reason of
acceleration, or otherwise);

      (b) any failure by Borrower (for a reason other than the failure of such
Lender to make a Loan) to prepay, borrow, continue or convert any Loan other
than a Base Rate Loan on the date or in the amount notified by Borrower; or

      (c) any assignment of a Eurodollar Rate Loan on a day other than the last
day of the Interest Period thereof as a result of a request by the Borrower
pursuant to Section 10.13.

Borrower's compensation to any Lender under this Section 3.05 is intended to put
such Lender in the same financial position it would have been in had the event
referred to in clauses (a), (b) or (c) not occurred, including any loss of
anticipated profits. Borrower's compensation to any such Lender will include any
loss or expense arising from the liquidation or reemployment of funds obtained
by it to maintain such Loan or from fees payable to terminate the deposits from
which such funds were obtained. Borrower shall also pay any customary
administrative fees charged by such Lender in connection with the foregoing. For
purposes of calculating amounts payable by Borrower to Lenders under this
Section 3.05, each Lender shall be deemed to have funded each Eurodollar Rate
Loan made by it at the Eurodollar Base Rate used in determining the Eurodollar
Rate for such Loan by a matching deposit or other borrowing in the London
interbank eurodollar market for a comparable amount and for a comparable period,
whether or not such Eurodollar Rate Loan was in fact so funded.

      3.06 MITIGATION OF OBLIGATIONS; REPLACEMENT OF LENDERS.

      (a) Designation of Different Lending Office. If any Lender requests
compensation under Section 3.04, or Borrower is required to pay any additional
amount to any Lender or any Governmental Authority for the account of any Lender
pursuant to Section 3.01, or if any Lender gives a notice pursuant to Section
3.02, then such Lender shall use reasonable efforts to designate a different
Lending Office for funding or booking its Loans hereunder or to assign its
rights and obligations hereunder to another of its offices, branches or
affiliates, if, in the judgment of such Lender, such designation or assignment
(i) would eliminate or reduce amounts payable pursuant to Section 3.01 or 3.04,
as the case may be, in the future, or eliminate the need for the notice pursuant
to Section 3.02, as applicable, and (ii) in each case, would not subject such
Lender to any unreimbursed cost or expense and would not otherwise be
disadvantageous to such Lender. Borrower hereby agrees to pay all reasonable
costs and expenses incurred by any Lender in connection with any such
designation or assignment.

      (b) Replacement of Lenders. If any Lender requests compensation under
Section 3.04, or if the Borrower is required to pay any additional amount to any
Lender or any Governmental Authority for the account of any Lender pursuant to
Section 3.01, the Borrower may replace such Lender in accordance with Section
10.13.

      3.07 SURVIVAL. All of Borrower's obligations under this Article III shall
survive termination of the Aggregate Commitments and repayment of all other
Obligations hereunder.

                                   ARTICLE V.
                         REPRESENTATIONS AND WARRANTIES

      Borrower represents and warrants to Agent and the Lenders that:

      5.01 EXISTENCE, QUALIFICATION AND POWER; COMPLIANCE WITH LAWS. Borrower
and each Subsidiary thereof (a) is duly organized or formed, validly existing
and in good standing under the Laws of the jurisdiction of its incorporation or
organization, (b) has all requisite power and authority and all requisite

except in each case referred to in clause (b)(i), (c) or (d), to the extent that
failure to do so would not reasonably be expected to have a Material Adverse
Effect.

      5.02 AUTHORIZATION; NO CONTRAVENTION. The execution, delivery and
performance by Borrower of each Loan Document, have been duly authorized by all
necessary corporate or other organizational action, and do not and will not (a)
contravene the terms of Borrower's Organization Documents; (b) conflict with or
result in any breach or contravention of, or the creation of any Lien under, or
require any payment to be made under (i) any Contractual Obligation (other than

writ or decree of any Governmental Authority or any arbitral award to which
Borrower or its property is subject; or (c) violate any Law. Borrower and each
Subsidiary thereof is in compliance with all Contractual Obligations referred to
in clause (b)(i), except to the extent that failure to do so would not
reasonably be expected to have a Material Adverse Effect.

      5.03 GOVERNMENTAL AUTHORIZATION; OTHER CONSENTS. No approval, consent,
exemption, authorization, or other action by, or notice to, or filing with, any
Governmental Authority or any other Person is necessary or required in
connection with the execution, delivery or performance by, or enforcement
against, Borrower of this Agreement or any other Loan Document, except for
recordings or filings in connection with the Liens granted to the Agent under
the Collateral Documents or filing of a redacted copy of the Loan Documents with
the SEC.

      5.04 BINDING EFFECT. This Agreement has been, and each other Loan
Document, when delivered hereunder, will have been, duly executed and delivered
by Borrower. This Agreement constitutes, and each other Loan Document when so
delivered will constitute, a legal, valid and binding obligation of Borrower,
enforceable against Borrower in accordance with its terms.

      5.05 FINANCIAL STATEMENTS; NO MATERIAL ADVERSE EFFECT.

      (a) The Audited Financial Statements (i) were prepared in accordance with
GAAP consistently applied throughout the period covered thereby, except as
otherwise expressly noted therein; (ii) fairly present the financial condition
of Borrower and its Subsidiaries as of the date thereof and their results of
operations for the period covered thereby in accordance with GAAP consistently
applied throughout the period covered thereby, except as otherwise expressly
noted therein; and (iii) show all material indebtedness and other liabilities,
direct or contingent, of Borrower and its Subsidiaries as of the date thereof,
including liabilities for taxes and material commitments.

      (b) The unaudited consolidated balance sheet of Borrower and its
Subsidiaries dated September 30, 2004, and the related consolidated statements
of income or operations, shareholders' equity and cash flows for the fiscal
quarter ended on that date (i) were prepared in accordance with GAAP
consistently applied throughout the period covered thereby, except as

                                       38
<PAGE>

otherwise expressly noted therein, and (ii) fairly present the financial
condition of Borrower and its Subsidiaries as of the date thereof and their
results of operations for the period covered thereby, subject, in the case of
clauses (i) and (ii), to the absence of footnotes and to normal year-end audit
adjustments.

      (c) Since the Closing Date and since the date of the Audited Financial
Statements, there has been no event or circumstance, either individually or in
the aggregate, that has had or could reasonably be expected to have a Material
Adverse Effect.

      (d) Since the date of the Audited Financial Statements, no material
Internal Control Event has occurred to the knowledge of Borrower's Chief
Executive Officer, Chief Financial Officer, Vice President-Finance, Treasurer or
Controller.

      5.06 LITIGATION AND JUDGMENTS. There are no actions, suits, proceedings,
claims or disputes pending or, to the knowledge of Borrower after due and
diligent investigation, threatened or contemplated, at law, in equity, in
arbitration or before any Governmental Authority, by or against Borrower or any
of its Subsidiaries or against any of their properties or revenues that (a)
purport to affect or pertain to this Agreement or any other Loan Document, or
any of the transactions contemplated hereby, or (b) are reasonably likely to
have a Material Adverse Effect. To the knowledge of Borrower after due and
diligent investigation, there is no outstanding unsatisfied money judgment
against Borrower or any of its Subsidiaries in an amount in excess of the
Threshold Amount, and there are no outstanding unsatisfied money judgments
against Borrower or any of its Subsidiaries which individually or in the
aggregate have or would have a Material Adverse Effect.

      5.07 NO DEFAULT. Neither Borrower nor any Subsidiary is in default under
or with respect to any Contractual Obligation that would, either individually or
in the aggregate, reasonably be expected to have a Material Adverse Effect. No
Default has occurred and is continuing or would result from the consummation of
the transactions contemplated by this Agreement or any other Loan Document.

      5.08 OWNERSHIP OF PROPERTY; LIENS. Each of Borrower and each Subsidiary
has good record and marketable title in fee simple to, or valid leasehold
interests in, all real property necessary or used in the ordinary conduct of its
business, except for such defects in title as would not, individually or in the
aggregate, reasonably be expected to have a Material Adverse Effect. The
property of Borrower and its Subsidiaries is subject to no Liens, other than
Liens permitted by Section 7.01.

      5.09 ENVIRONMENTAL COMPLIANCE. Borrower and its Subsidiaries conduct in
the ordinary course of business a review of the effect of existing Environmental
Laws and claims alleging potential liability or responsibility for violation of
any Environmental Law on their respective businesses, operations and properties,
and as a result thereof Borrower has reasonably concluded that, except as
specifically disclosed in Schedule 5.09, such Environmental Laws and claims
would not, individually or in the aggregate, reasonably be expected to have a
Material Adverse Effect.

                                       39
<PAGE>

      5.10 INSURANCE. The properties and businesses of Borrower and its
Subsidiaries are insured with financially sound and reputable insurance
companies (including Lloyds of London syndicates) not Affiliates of Borrower, in
such amounts (after giving effect to any self-insurance compatible with the
following standards), with such deductibles and covering such risks as are
customarily carried by companies engaged in similar businesses and owning
similar properties in localities where Borrower or the applicable Subsidiary
operates.

      5.11 TAXES. Borrower and its Subsidiaries have filed all Federal, state
and other material tax returns and reports required to be filed, and have paid
all Federal, state and other material taxes, assessments, fees and other
governmental charges levied or imposed upon them or their properties, income or
assets otherwise due and payable, except those which are being contested in good
faith by appropriate proceedings diligently conducted and for which adequate
reserves have been provided in accordance with GAAP. To Borrower's knowledge,
there is no proposed tax assessment against Borrower or any Subsidiary that
would, if made, have a Material Adverse Effect.

      5.12 ERISA COMPLIANCE.

      (a) Each Plan is in compliance in all material respects with the
applicable provisions of ERISA, the Code and other Federal or state Laws. Each
Plan that is intended to qualify under Section 401(a) of the Code has received a
favorable determination letter from the IRS or an application for such a letter
is currently being processed by the IRS with respect thereto and, to the best
knowledge of Borrower, nothing has occurred which would prevent, or cause the
loss of, such qualification. Borrower and each ERISA Affiliate have made all
required contributions to each Plan subject to Section 412 of the Code, and no
application for a funding waiver or an extension of any amortization period
pursuant to Section 412 of the Code has been made with respect to any Plan.

      (b) There are no pending or, to the best knowledge of Borrower, threatened
claims, actions or lawsuits, or action by any Governmental Authority, with
respect to any Plan that would be reasonably be expected to have a Material
Adverse Effect. There has been no prohibited transaction or violation of the
fiduciary responsibility rules with respect to any Plan that has resulted or
would reasonably be expected to result in a Material Adverse Effect.

      (c) No ERISA Event has occurred or is reasonably expected to occur; (ii)
no Pension Plan has any Unfunded Pension Liability in excess [***] of such
Pension Plan's benefit liabilities under Section 4001(a)(16); (iii) neither
Borrower nor any ERISA Affiliate has incurred, or reasonably expects to incur,
any liability under Title IV of ERISA with respect to any Pension Plan (other
than premiums due and not delinquent under Section 4007 of ERISA), which would
reasonably be expected to have a Material Adverse Effect; (iv) neither Borrower
nor any ERISA Affiliate has incurred, or reasonably expects to incur, any
liability (and no event has occurred which, with the giving of notice under
Section 4219 of ERISA, would result in such liability) under Sections 4201 or
4243 of ERISA with respect to a Multiemployer Plan; and (v) neither Borrower nor
any ERISA Affiliate has engaged in a transaction that could be subject to

      5.13 SUBSIDIARIES. As of the Closing Date, Borrower has no Subsidiaries.
As of the Closing Date, Parent has no operating Subsidiaries other than Borrower

validly issued and are fully paid and nonassessable and are owned by Parent free
and clear of all Liens.

      5.14 MARGIN REGULATIONS; INVESTMENT COMPANY ACT; PUBLIC UTILITY HOLDING
COMPANY ACT.

      (a) Borrower is not engaged and will not engage, principally or as one of
its important activities, in the business of purchasing or carrying margin stock
(within the meaning of Regulation U issued by the FRB), or extending credit for
the purpose of purchasing or carrying margin stock.

      (b) None of Borrower, any Person Controlling Borrower, or any Subsidiary
(i) is a "holding company," or a "subsidiary company" of a "holding company," or
an "affiliate" of a "holding company" or of a "subsidiary company" of a "holding
company," within the meaning of the Public Utility Holding Company Act of 1935,
or (ii) is or is required to be registered as an "investment company" under the
Investment Company Act of 1940.

      5.15 DISCLOSURE. Borrower has disclosed to Agent and Lenders all
agreements, instruments and corporate or other restrictions to which it or any
of its Subsidiaries is subject, and all other matters known to it, that,
individually or in the aggregate, would reasonably be expected to result in a
Material Adverse Effect. No report, financial statement, certificate or other
information furnished (whether in writing or orally) by or on behalf of Borrower
to Agent or any Lender in connection with the transactions contemplated hereby
and the negotiation of this Agreement or delivered hereunder or under any other
Loan Document (in each case, as modified or supplemented by other information so
furnished) contains any material misstatement of fact or omits to state any
material fact necessary to make the statements therein, in the light of the
circumstances under which they were made, not misleading; provided that, with
respect to projected financial information, Borrower represents only that such
information was prepared in good faith based upon assumptions believed to be
reasonable at the time.

      5.16 COMPLIANCE WITH LAWS. Each of Borrower and each Subsidiary is in
compliance in all material respects with the requirements of all Laws and all
orders, writs, injunctions and decrees applicable to it or to its properties,
except in such instances in which (a) such requirement of Law or order, writ,
injunction or decree is being contested in good faith by appropriate proceedings
diligently conducted or (b) the failure to comply therewith, either individually
or in the aggregate, would not reasonably be expected to have a Material Adverse
Effect.

      5.17 INTELLECTUAL PROPERTY; LICENSES, ETC. Borrower and its Subsidiaries
own, or possess the right to use, all of the trademarks, service marks, trade
names, copyrights, patents, patent rights, franchises, licenses and other
intellectual property rights ("IP Rights") that are reasonably necessary for the
operation of their respective businesses, without conflict with the rights of
any other Person. To the best knowledge of Borrower, no slogan or other
advertising device, product, process, method, substance, part or other material
now employed, or now contemplated to be employed, by Borrower or any Subsidiary
infringes upon any rights held by

                                       41
<PAGE>

any other Person. No claim or litigation regarding any of the foregoing is
pending or, to the best knowledge of Borrower, threatened, which, either
individually or in the aggregate, would reasonably be expected to have a
Material Adverse Effect.

      5.18 SOLVENCY. The Borrower is Solvent and shall be Solvent immediately
after the consummation of the transactions contemplated by this Agreement. As
used herein, a Person is "Solvent" on a particular date, if, on such date both
(a) (i) the then fair saleable value of the property of such Person on a going
concern basis is (A) greater than the total amount of liabilities (including
contingent liabilities) of such Person as they mature in the ordinary course and
(B) not less than the amount that will be required to pay the probable
liabilities on such Person's then-existing debts as they become absolute and
matured considering all financing alternatives and potential asset sales
reasonably available to such Person; (ii) such Person's capital is not
unreasonably small in relation to its business or any contemplated or undertaken
transaction; and (iii) such Person does not intend to incur, or believe (nor
should it reasonably believe) that it will incur, debts beyond its ability to
pay such debts as they become due; and (b) such Person is "solvent" within the
meaning given that term and similar terms under applicable laws relating to
fraudulent transfers and conveyances. For purposes of this definition, the debts
and liabilities of a Person, contingent or otherwise, shall include the amount
of all debts and liabilities that are relevant under Section 548 of Title 11 of
the United States Code or any applicable provisions of comparable state law
(collectively, the "Fraudulent Transfer Laws"), and the assets of a Person shall
give effect to the value (as determined under the applicable provisions of the
Fraudulent Transfer Laws) of any rights to subrogation, reimbursement,
indemnification or contribution of such Person pursuant to applicable Law or
pursuant to the terms of any agreement.

      5.19 COLLATERAL AND SECURITY DOCUMENTS.

      (a) Borrower owns all right, title and interest in and to the Aircraft
Collateral (and any other Collateral) free and clear of all Liens other than (i)
the security interests in favor of the Administrative Agent securing the
Obligations, or (ii) Liens permitted by Section 7.01 that are junior and
subordinate to the security interests created by the Collateral Documents, or
(iii) Liens on the Aircraft Collateral permitted under subsections (e) and (f)
of Section 7.01.

      (b) The Security Agreement (and any of other Collateral Documents) create,
in favor of the Administrative Agent for the benefit of itself and the Lenders,
a legal, valid and enforceable security interest in all of Borrower's right,
title and interest in all of the Aircraft Collateral (and any other Collateral),
which security interest has been duly perfected and has priority over any other
Liens on the Collateral (other than Liens on the Aircraft Collateral described
in subsections (e) and (f) of Section 7.01).

      (c) Each of the Pledged Aircraft is a U.S. registered Stage 3 Aircraft,
and Borrower is a citizen of the United States for purposes of the U.S. Federal
Aviation Act.

      (d) Borrower is, and continuously during the five years immediately
preceding the date of this Agreement has been, an Alaska corporation. Borrower's
chief executive office is, and continuously during the five years immediately
preceding the date of this Agreement has been, located in Seattle, Washington.

                                       42
<PAGE>

      (e) No Aircraft, at the time Agent's security interest in such Aircraft
attaches, will be subject to any interest, other than an interest held by
Borrower, that is recorded in the FAA Registry.

      (f) The Engines pledged pursuant to the Security Agreement are of the same
series, model and make and the Engines, taken as a group, have approximately the
same aggregate value as the engines upon which the determination of Current
Market Value in each Qualified Appraisal was based.

      (g) The representations and warranties in this Section 5.19 (other than
Section 5.19(e)) are made on and as of the date of this Agreement and, with
respect to the representations and warranties in subsections (a), (b) and (c)
hereof, on and as of each date thereafter.

      5.20 BURDENSOME AGREEMENTS. Neither Borrower nor any Subsidiary has any
Contractual Obligation (other than this Agreement or any other Loan Document)
that (a) limits the ability (i) of any Subsidiary to make Restricted Payments to
Borrower or to otherwise transfer property to Borrower, (ii) of any Subsidiary
to Guarantee any obligations of Borrower under any of the Loan Documents or
(iii) of Borrower or any Subsidiary to create, incur, assume or suffer to exist
Liens on property of such Person; provided, however, that this clause (iii)
shall not prohibit any negative pledge incurred or provided in favor of any
holder of Indebtedness permitted under this Agreement solely to the extent any
such negative pledge relates to the property financed by or the subject of such
Indebtedness; or (b) requires the grant of a Lien to secure an obligation of
such Person if a Lien is granted to secure another obligation of such Person.

         5.21 COMPLIANCE WITH OFAC RULES AND REGULATIONS. None of Borrower, any
Subsidiary of Borrower or any Affiliate of Borrower (a) is a Sanctioned Person,
(b) has more than 15% of its assets in Sanctioned Countries, or (c) derives more

operations in, finance any investments or activities in or make any payments to,
a Sanctioned Person or a Sanctioned Country. "OFAC" means the U.S. Department of

reasonably request.

Documents required to be delivered pursuant to Section 6.01(a) or (b) or Section
6.02(c) (to the extent any such documents are included in materials otherwise
filed with the SEC) may be delivered electronically and if so delivered, shall
be deemed to have been delivered on the date (i) on which the Borrower posts
such documents, or provides a link thereto on the Borrower's website on the
Internet at the website address listed on Schedule 10.02; or (ii) on which such

Borrower hereby acknowledges that (a) Agent will make available to Lenders
materials and/or information provided by or on behalf of Borrower hereunder
(collectively, "Borrower Materials") by posting Borrower Materials on IntraLinks
or another similar electronic system (the "Platform") and (b) certain of the
Lenders may be "public-side" Lenders (i.e., Lenders that do not wish to receive
material non-public information with respect to Borrower or its securities)
(each, a "Public Lender"). Borrower hereby agrees that (w) all Borrower
Materials that are to be made available to Public Lenders shall be clearly and
conspicuously marked "PUBLIC" which, at a minimum, shall mean that the word
"PUBLIC" shall appear prominently on the first page thereof, provided, however,
that no document available on the website of the SEC need contain any legend;
(x) by marking Borrower Materials "PUBLIC," Borrower shall be

                                       45
<PAGE>

deemed to have authorized Agent and the Lenders to treat such Borrower Materials
as either publicly available information or not material information (although
it may be sensitive and proprietary) with respect to Borrower or its securities
for purposes of United States Federal and state securities laws; (y) all
Borrower Materials marked "PUBLIC" are permitted to be made available through a
portion of the Platform designated "Public Investor;" and (z) Agent shall be
entitled to treat any Borrower Materials that are not marked "PUBLIC" (other
than documents available on the SEC website) as being suitable only for posting
on a portion of the Platform not designated "Public Investor."

      6.03 NOTICES. Not later than five Business Days after Borrower obtains
knowledge thereof, notify Agent and each Lender:

      (a) of the occurrence of any Default to the knowledge of Borrower's chief
financial officer or any other officer, employee or agent of Borrower who is
responsible for administering the applicable provisions hereof or who is
responsible for communicating with Administrative Agent or Lenders regarding
this Agreement or any of the matters contemplated by this Agreement;

      (b) of any matter that has resulted or would reasonably be expected to
result in a Material Adverse Effect, including (i) breach or non-performance of,
or any default under, a Contractual Obligation of Borrower or any Subsidiary;
(ii) any dispute, litigation, investigation, proceeding or suspension between
Borrower or any Subsidiary and any Governmental Authority; or (iii) the
commencement of, or any material development in, any litigation or proceeding
affecting Borrower or any Subsidiary, including pursuant to any applicable
Environmental Laws;

      (c) of the occurrence of any ERISA Event; and

      (d) of any material change in accounting policies or financial reporting
practices by Borrower or any Subsidiary.

Each notice pursuant to this Section shall be accompanied by a statement of a
Responsible Officer of Borrower setting forth details of the occurrence referred
to therein and stating what action Borrower has taken and proposes to take with
respect thereto. Each notice pursuant to Section 6.03(a) shall describe with
particularity any and all provisions of this Agreement and any other Loan
Document that have been breached.

      6.04 PAYMENT OF OBLIGATIONS. Pay and discharge as the same shall become
due and payable, all its obligations and liabilities, including (a) all tax
liabilities, assessments and governmental charges or levies upon it or its
properties or assets, unless the same are being contested in good faith by
appropriate proceedings diligently conducted and adequate reserves in accordance
with GAAP are being maintained by Borrower or such Subsidiary; (b) all lawful
claims which, if unpaid, would by law become a Lien upon its property; and (c)
all Indebtedness, as and when due and payable, but subject to any subordination
provisions contained in any instrument or agreement evidencing such
Indebtedness.

      6.05 PRESERVATION OF EXISTENCE, ETC. (a) Preserve, renew and maintain in
full force and effect its legal existence and good standing under the Laws of
the jurisdiction of its

                                       46
<PAGE>

organization except in a transaction permitted by Section 7.02; (b) take all
reasonable action to maintain all rights, privileges, permits, licenses and
franchises necessary or desirable in the normal conduct of its business, except
to the extent that failure to do so would not reasonably be expected to have a
Material Adverse Effect; and (c) preserve or renew all of its registered
patents, trademarks, trade names and service marks, the non-preservation of
which would reasonably be expected to have a Material Adverse Effect.

      6.06 MAINTENANCE OF PROPERTIES. (a) Maintain, preserve and protect or
replace all of its material properties and equipment necessary in the operation
of its business in good working order and condition, ordinary wear and tear
excepted; (b) make all necessary repairs thereto and renewals and replacements
thereof except where the failure to do so would not reasonably be expected to
have a Material Adverse Effect; and (c) use not less than the standard of care
typical in the industry in the operation and maintenance of its facilities.

      6.07 MAINTENANCE OF INSURANCE.

      (a) In addition to insurance requirements set forth in the Collateral
Documents, maintain with financially sound and reputable insurance companies
(including Lloyds of London syndicates) not Affiliates of Borrower, insurance
with respect to its properties and business against loss or damage of the kinds
customarily insured against by Persons engaged in the same or similar business
(operating similar aircraft in similar markets), of such types and in such
amounts (after giving effect to any self-insurance and/or deductible compatible
with the following standards) as are customarily carried under similar
circumstances by such other Persons and providing for not less than 30 days'
prior notice to Agent of termination or cancellation of such insurance. Without
limiting the generality of the foregoing, except as provided in paragraph (b) of
this Section 6.07, Borrower will at all times carry or cause to be carried at
its expense (or at the expense of the lessee of such Aircraft), aircraft
liability insurance including passenger legal liability, property damage
liability and contractual liability (exclusive of manufacturer's product
liability insurance) with respect to each Aircraft owned by Borrower, (A) in an
amount not less than the greater of (x) the amounts of public liability and
property damage insurance from time to time determined by Borrower to be prudent
and (y) $300,000,000 per occurrence, (B) of the type and covering the risks as
from time to time determined by Borrower to be prudent and (C) which is
maintained in effect with insurers of recognized responsibility and reputation.

      (b) During any period that an Aircraft is on the ground and not in
operation, Borrower may carry or cause to be carried, in lieu of the insurance
required by Section 6.07(a) above, insurance with respect to such Aircraft
otherwise conforming with the provisions of such Section 6.07(a) except that (A)
the amounts of coverage shall not be required to exceed the amounts of public
liability and property damage insurance from time to time applicable to Aircraft
owned or leased by Borrower of the same type as the Aircraft which comprise
Borrower's fleet and which are on the same ground and not in operation; and (B)
the scope of the risks covered and the type of insurance shall be the same as
from time to time shall be applicable to Aircraft owned or leased by Borrower of
the same type which comprise Borrower's fleet and which are on the ground and
not in operation; provided that if Borrower then has no other similarly situated
Aircraft, the terms of such insurance during such period shall conform to
prudent industry standards.

                                       47
<PAGE>

      6.08 COMPLIANCE WITH LAWS. Comply in all material respects with the
requirements of all Laws and all orders, writs, injunctions and decrees
applicable to it or to its business or property, except in such instances in
which (a) such requirement of Law or order, write, injunction or decree is being
contested in good faith by appropriate proceedings diligently conducted; or (b)
the failure to comply therewith would not reasonably be expected to have a
Material Adverse Effect.

      6.09 BOOKS AND RECORDS. (a) Maintain proper books of record and account,
in which full, true and correct entries in conformity with GAAP consistently
applied shall be made of all financial transactions and matters involving the
assets and business of Borrower or such Subsidiary, as the case may be; and (b)
maintain such books of record and account in material conformity with all
applicable requirements of any Governmental Authority having regulatory
jurisdiction over Borrower or such Subsidiary, as the case may be.

      6.10 INSPECTION RIGHTS. Permit representatives and independent contractors
of Agent and each Lender to visit and inspect any of its properties, to examine
its corporate, financial and operating records, and to discuss its affairs,
finances and accounts with its directors, officers, and independent public
accountants, at such reasonable times during normal business hours and as often
as may be reasonably desired, upon reasonable advance notice to Borrower;
provided, however, that when an Event of Default exists Agent or any Lender (or
any of their respective representatives or independent contractors) may do any
of the foregoing at the expense of Borrower at any time during normal business
hours.

      6.11 USE OF PROCEEDS. Use the proceeds of the Borrowings for capital
expenditures, working capital and other general corporate purposes not in
contravention of any Law or of any Loan Document.

      6.12 FINANCIAL COVENANTS.

      (a) Consolidated Tangible Net Worth. Maintain Consolidated Tangible Net
Worth equal to or greater than the sum of (i) [***], plus (ii) the sum of the
following for Borrower and its Subsidiaries on a consolidated basis: (A) as of
the end of the fiscal quarter ended June 30, 2005, [***] of net income after
income taxes (without subtracting losses) earned in the such fiscal quarter plus
(B) as of the end of the fiscal year ended December 31, 2005, [***] of net
income after income taxes (without subtracting losses) earned in such full

income after income taxes (without subtracting losses) earned in such full
fiscal year, in each case with net income determined by excluding (x) unusual,
non-cash special charges and credits, (y) Permitted Asset Adjustments and (z)
the marked-to-market Swap Termination value for Swap Contracts that have not
been closed out. This amount will be calculated at the end of each reporting

reporting period.

      (b) Leverage Ratio. Maintain a ratio of Consolidated Funded Debt and

      (c) Fixed Charge Coverage Ratio. Maintain on a consolidated basis a Fixed

statements, using the results of the twelve-month period ending with that
reporting period. The scheduled current portion of long-term liabilities will be
measured as of the last day of the calculation period.

      6.13 COLLATERAL RECORDS. To execute and deliver promptly to Agent, from
time to time, solely for Agent's convenience in maintaining a record of the
Collateral, such written statements and schedules as Agent may reasonably
require designating, identifying or describing the Collateral. The failure by
Borrower, however, to promptly give Agent such statements or schedules shall not
affect, diminish, modify or otherwise limit the Liens on the Collateral granted
pursuant to the Collateral Documents.

      6.14 SECURITY INTERESTS. To (a) defend the Collateral against all claims
and demands of all Persons at any time claiming the same or any interest
therein, (b) comply with the requirements of all state and federal laws in order
to grant to Agent and Lenders valid and perfected first priority security
interests in the Collateral, with perfection, in the case of any investment
property, deposit account or letter of credit, being effected by giving Agent
control of such investment property or deposit account or letter of credit,
rather than by the filing of a Uniform Commercial Code ("UCC") financing
statement with respect to such investment property, and (c) do whatever Agent
may reasonably request, from time to time, to effect the purposes of this
Agreement and the other Loan Documents, including filing notices of liens, UCC
financing statements, and amendments, renewals and continuations thereof;
cooperating with Agent's representatives; keeping stock records; obtaining
waivers from landlords and mortgagees and from warehousemen and their landlords
and mortgages; and, paying claims which might, if unpaid, become a Lien on the
Collateral. Agent is hereby authorized by Borrower to file any UCC financing
statements covering the Collateral whether or not Borrower's signatures appear
thereon.

      6.15 COLLATERAL.

      (a) Collateral Review Date. On or before the last Business Day of each
June and December (each a "Collateral Review Date") beginning on June 30, 2005,

Aircraft as of a Valuation Date that is no earlier than 30 days prior to the
applicable Collateral Review Date.

      (b) Cure of Collateral Shortfall or Over Advance. If a Collateral
Shortfall exists or Borrower elects to cure an Over Advance pursuant to Section

            (i) within 15 Business Days after the date of such Collateral
      Shortfall or five Business Days after the date of an Over Advance,
      executing and delivering to the Administrative Agent a supplement to the
      Security Agreement in substantially the form of Schedule I to the Security
      Agreement (a "Security Agreement Supplement") and providing the
      Administrative Agent with evidence satisfactory to it that:

                  (A) the Security Agreement, as supplemented by such Security
            Agreement Supplement, has granted a security interest to the
            Administrative Agent in one or more Stage 3 Aircraft owned by
            Borrower (the "Added Pledged Aircraft") that was not or were not
            already Pledged Aircraft as security for the Obligations;

                  (B) such security interest is a perfected first-priority
            security interest and each Added Pledged Aircraft is free and clear
            of: (i) any Liens other than Liens permitted by Section 7.01; and
            (ii) any other interest that has been recorded in the records the
            Aircraft Registry of United States Department of Transportation,
            Federal Aviation Administration (the "FAA Registry");

                  (C) the Current Market Value of the Added Pledged Aircraft is
            sufficient, in combination with any Cash Collateral pledged in
            accordance with Section 6.15(b)(ii), to cure the Collateral
            Shortfall or the Over Advance, as applicable;

                  (D) all insurance policies required by this Agreement or the
            Security Agreement with respect to the Added Pledged Aircraft have
            been duly issued and remain in force in accordance therewith and
            that Administrative Agent and Lenders have been named as loss payees
            to the extent of their interest (the lower of (x) the Current Market
            Value as reflected on the last Qualified Appraisal or (y) the
            Obligations outstanding at the time of payment of insurance
            proceeds) and additional insured under all policies of casualty
            insurance and as additional insured under all policies of liability
            insurance; and

                  (E) the execution, delivery and performance of the Security
            Agreement Supplement have been duly authorized by all necessary
            corporate action of Borrower and the Security Agreement, as amended
            by such supplement, constitutes the legal, valid and binding
            obligation of Borrower; or

            (ii) within 15 Business Days after such Collateral Shortfall or or
      five Business Days after the date of Over Advance, executing and
      delivering to the Administrative Agent, a Cash Pledge Agreement or an
      amendment thereto pledging Cash Collateral that qualifies in all respects
      for inclusion in the Borrowing Base. Such additional Cash Collateral shall
      be in an amount sufficient, in combination with any Aircraft Collateral
      pledged in accordance with Section 6.15(b)(i), to cure the Collateral
      Shortfall or the Over Advance, as applicable.

If Borrower elects to cure an Collateral Shortfall or an Over Advance pursuant
to clause (i) above, the Administrative Agent may also require that Borrower
provide a legal opinion

                                       50
<PAGE>

issued by FAA counsel for Borrower acceptable to the Administrative Agent
covering some or all of the matters covered by the legal opinion attached hereto
as Exhibit E-2.

      (c) Substitution of Engines. Provided that no Event of Default has
occurred and is continuing, Borrower may, from time to time, send the
Administrative Agent a written request to substitute an Engine that is not
covered by the Security Agreement (an "Added Engine") for an Engine that is
covered by the Security Agreement which may include an Engine that has been
subject to an Event of Loss (a "Removed Engine"). The Administrative Agent shall
release its security interest in the Removed Engine within five Business Days
after the date when Borrower has executed and delivered to the Administrative
Agent a Security Agreement Supplement covering the Added Engine and provided the
Administrative Agent with evidence satisfactory to it that:

            (i) the Security Agreement, as supplemented by such Security
      Agreement Supplement, has granted a security interest to the
      Administrative Agent in the Added Engine as security for the Obligations;

            (ii) such security interest is a perfected first-priority security
      interest and the Added Engine is free and clear of: (A) any Liens other
      than Liens permitted by Section 7.01; and (B) any other interest that has
      been recorded in the FAA Registry;

            (iii) the Added Engine is a Stage 3 Engine of the same or improved
      make and model as the Removed Engine;

            (iv) all insurance policies and/or endorsements required by this
      Agreement or the Security Agreement with respect to the Added Engine have
      been duly issued and remain in force in accordance therewith and that
      Administrative Agent and Lenders have been named as additional insured and
      under all policies of casualty insurance and as additional insured under
      all policies of liability insurance;

            (v) if requested by the Administrative Agent, the execution,
      delivery and performance of the Security Agreement Supplement has been
      duly authorized by all necessary corporate action of Borrower and the
      Security Agreement, as amended by such supplement, constitutes the legal,
      valid and binding obligation of Borrower; and

            (vi) if requested by the Administrative Agent, a legal opinion
      issued by counsel for Borrower acceptable to the Administrative Agent
      covering some or all of the matters covered by the legal opinion attached
      hereto as Exhibit E as they apply to the Added Engine.

      (d) Substitution of Aircraft. Provided that no Event of Default has
occurred and is continuing, Borrower may, from time to time, send the
Administrative Agent a written request to substitute an Aircraft that is not
covered by the Security Agreement (an "Added Aircraft") for an Aircraft that is
covered by the Security Agreement which may include an Aircraft that has been
subject to an Event of Loss (a "Removed Aircraft"). The Administrative Agent
shall release its security interest in the Removed Aircraft within five Business
Days after the Aircraft Substitution Request Date. "Aircraft Substitution
Request Date" means the date when Borrower

                                       51
<PAGE>

has executed and delivered to the Administrative Agent a Security Agreement
Supplement covering the Added Aircraft and provided the Administrative Agent
with evidence satisfactory to it of each of the following:

            (i) the Security Agreement, as supplemented by such Security
      Agreement Supplement, has granted a security interest to the
      Administrative Agent in the Added Aircraft as security for the
      Obligations;

            (ii) such security interest is a perfected first-priority security
      interest and the Added Aircraft is free and clear of any Liens or option
      other than Liens permitted by Section 7.01;

            (iii) the Current Market Value of the Added Aircraft is equal to or
      greater than the Current Market Value of the Removed Aircraft, each as set
      forth in a Qualified Appraisal with a Valuation Date no earlier than 30
      days prior to the Aircraft Substitution Request Date;

            (iv) all insurance policies and/or endorsements required by this
      Agreement or the Security Agreement with respect to the Added Engine have
      been duly issued and remain in force in accordance therewith and that
      Administrative Agent and Lenders have been named as loss payees to the
      extent of their interest (the lower of (x) the Current Market Value as
      reflected on the last Qualified Appraisal or (y) the Obligations
      outstanding at the time of payment of insurance proceeds) and additional
      insured under all policies of casualty insurance and as additional insured
      under all policies of liability insurance;

            (v) if requested by the Administrative Agent, the execution,
      delivery and performance of the Security Agreement Supplement has been
      duly authorized by all necessary corporate action of Borrower and the
      Security Agreement, as amended by such supplement, constitutes the legal,
      valid and binding obligation of Borrower; and

            (vi) if requested by the Administrative Agent, a legal opinion
      issued by counsel for Borrower acceptable to the Administrative Agent
      covering some or all of the matters covered by the legal opinion attached
      hereto as Exhibit E as they apply to the Added Aircraft.

      (e) Release of Collateral. If (i) Borrower reduces the Aggregate
Commitments in accordance with Section 2.04 or has, through Qualified
Appraisals, demonstrated that an Aircraft can be removed from the Aircraft
Collateral and still leave the Aircraft Collateral equal to or greater than
[***] of the Aggregate Commitments, (ii) Borrower provides to the Administrative
Agent a Qualified Appraisal with a Valuation Date no earlier than 30 days prior
to Borrower's Release Request, and (iii) no Default under Sections 8.01(a) or
8.01(f) and no Event of Default has occurred and is continuing, then Borrower
may send the Administrative Agent a written request (a "Release Request") to
release one or more Aircraft from the security interest created by the Security
Agreement. Each such Release Request shall identify the specific Aircraft to be
released and shall state the Current Market Value of each Aircraft to be
released and of the Aircraft Collateral after giving effect to such release. If
the Qualified Appraisal confirms that,

*     Indicates that certain information contained herein has been omitted and
      filed separately with the Securities and Exchange Commission. Confidential
      treatment has been requested with respect to the omitted portions.

                                       52
<PAGE>

after giving effect to such release, the Current Market Value of the Aircraft
Collateral would be greater than or equal to [***] of the Aggregate Commitments
as so reduced, then the Administrative Agent will, within five Business Days
after its receipt of the Release Request, release the security interest in such
Aircraft and/or Engines.

      (f) Substitution of Cash Collateral. Borrower may request the release of
the Administrative Agent's security interest in the Aircraft Collateral in
exchange for a security interest in Cash Collateral acceptable to the
Administrative Agent and Requisite Lenders or a release of Cash Collateral in
exchange for a security interest in Aircraft Collateral. Borrower's right to
obtain such release, in the case of Aircraft Collateral, shall be subject to
Borrower executing and delivering to Administrative Agent a Cash Pledge
Agreement covering the Cash Collateral and Borrower, the Administrative Agent
and Requisite Lenders reaching agreement regarding (i) the perfection, priority
and valuation of the Cash Collateral; and (iii) the amendments to this Agreement
necessary or appropriate in light of such substitution of collateral. Borrower's
right to obtain such release of Cash Collateral shall be subject to Borrower
executing and delivering to Administrative Agent a Security Agreement Supplement
covering additional Aircraft Collateral that meets all the requirements of (b)
above for curing any Collateral Shortfall (assuming that the Agent has released
the Cash Collateral that Borrower has requested be released).

      (g) Duration of Valuation. Except as otherwise provided in Section
6.15(h), the Current Market Value of a Pledged Aircraft as set forth in the
Qualified Appraisal associated with a Collateral Review Date or a substitution
of Pledged Aircraft shall remain in effect until the Qualified Appraisal
associated with the earlier of the next Collateral Review Date or the next
request for a substitution of Pledged Aircraft.

      (h) Event of Loss. Within ten (10) days after the occurrence of an Event
of Loss with respect to a Pledged Aircraft, Borrower shall notify the
Administrative Agent and Lenders in writing of such Event of Loss, which notice
shall state the Current Market Value of the affected Pledged Aircraft and
certify that Borrower has filed a casualty insurance claim with respect to such
Event of Loss. Immediately upon the occurrence of an Event of Loss with respect
to any Pledged Aircraft, the Current Market Value of the Aircraft Collateral
shall immediately be reduced by the Current Market Value of the Pledged Aircraft
that was subject to such Event of Loss. During the Claim Collateral Period, the
Current Market Value of the Aircraft Collateral shall be increased by the Agreed
Value Amount less the amount, if any, attributable to any underwriter of such
insurance that has become insolvent or that has commenced, had commenced against
it, or has otherwise become subject to, a bankruptcy, receivership or other
insolvency proceeding. Immediately at the end of such Claim Collateral Period,
the Current Market Value of the Aircraft Collateral shall no longer include such
Agreed Value Amount and any proceeds that exceed the Current Market Value of the
Aircraft received by the Agent shall either be used to reduce the Outstanding
Amount or remitted to Borrower (a) at the option of Borrower if, at such time,
no Default or Event of Default has occurred and is continuing or would occur if
such proceeds were remitted to Borrower and Borrower would otherwise be entitled
to re-borrow the amount of such proceeds in accordance with the terms of this
Agreement; and (b) otherwise, at the option of the Agent.

*     Indicates that certain information contained herein has been omitted and
      filed separately with the Securities and Exchange Commission. Confidential
      treatment has been requested with respect to the omitted portions.

      6.16 STATE OF INCORPORATION. Borrower shall give the Administrative Agent
at least 30 days' prior written notice thereof before changing its state of
corporation or otherwise ceasing to be an Alaska corporation.

      6.17 FURTHER ASSURANCES. Promptly upon request by the Administrative Agent
or the Required Lenders, do, execute, acknowledge, authorize, deliver, record,
re-record, file, re-file, register and re-register, any and all such further
acts, deeds, conveyances, security agreements, aircraft mortgages, assignments,
estoppel certificates, financing statements and continuations thereof,
termination statements, notices of assignment, transfers, certificates,
assurances and other instruments the Administrative Agent or such Lenders, as
the case may be, may reasonably require from time to time in order (i) to carry
out more effectively the purposes of any Collateral Document, (ii) to subject to
the Liens created by any of the Collateral Documents any of the properties,
rights or interests covered by any of the Collateral Documents, (iii) to perfect
and maintain the validity, effectiveness and priority of any of the Collateral
Documents and the Liens intended to be created thereby, and (iv) to better
assure, convey, grant, assign, transfer, preserve, protect and confirm to the
Agent and the Lenders the rights granted or now or hereafter intended to be
granted to the Agent and/or the Lenders under the Collateral Documents or under
any other document, instrument or agreement from time to time executed by
Borrower in connection therewith.

                                  ARTICLE IX.
                              ADMINISTRATIVE AGENT

      9.01 APPOINTMENT AND AUTHORIZATION OF ADMINISTRATIVE AGENT. Each of the
Lenders hereby irrevocably appoints Bank of America to act on its behalf as
Administrative Agent hereunder and under the other Loan Documents and authorizes
Agent to take such actions on its behalf and to exercise such powers as are
delegated to Agent by the terms hereof and thereof, together with such actions
and powers as are reasonably incidental thereto. The provisions of this Article
are solely for the benefit of Agent and the Lenders, and Borrower shall not have
rights as a third party beneficiary of any of such provisions.

      9.02 RIGHTS AS A LENDER. The Person serving as Agent hereunder shall have
the same rights and powers in its capacity as a Lender as any other Lender and
may exercise the same as though it were not Agent and the term "Lender" or
"Lenders" shall, unless otherwise expressly indicated or unless the context
otherwise requires, include the Person serving as Agent hereunder in its
individual capacity. Such Person and its Affiliates may accept deposits from,
lend money to, act as the financial advisor or in any other advisory capacity
for and generally engage in any kind of business with the Borrower or any
Subsidiary or other Affiliate thereof as if such Person were not Agent hereunder
and without any duty to account therefor to Lenders.

      9.03 EXCULPATORY PROVISIONS. Agent shall not have any duties or
obligations except those expressly set forth herein and in the other Loan
Documents. Without limiting the generality of the foregoing, Agent:

      (a) shall not be subject to any fiduciary or other implied duties,
regardless of whether a Default has occurred and is continuing;

      (b) shall not have any duty to take any discretionary action or exercise
any discretionary powers, except discretionary rights and powers expressly
contemplated hereby or by the other Loan Documents that Agent is required to
exercise as directed in writing by the

                                       61
<PAGE>

Required Lenders (or such other number or percentage of the Lenders as shall be
expressly provided for herein or in the other Loan Documents), provided that
Agent shall not be required to take any action that, in its opinion or the
opinion of its counsel, may expose Agent to liability or that is contrary to any
Loan Document or applicable Law; and

      (c) shall not, except as expressly set forth herein and in the other Loan
Documents, have any duty to disclose, and shall not be liable for the failure to
disclose, any information relating to Borrower or any of its Affiliates that is
communicated to or obtained by the Person serving as Agent or any of its
Affiliates in any capacity.

      (d) Agent shall not be liable for any action taken or not taken by it (i)
with the consent or at the request of the Required Lenders (or such other number
or percentage of the Lenders as shall be necessary, or as Agent shall believe in
good faith shall be necessary, under the circumstances as provided in Sections
8.02 and 10.01 or (ii) in the absence of its own gross negligence or willful
misconduct. Agent shall be deemed not to have knowledge of any Default unless
and until written notice describing such Default is given to Agent by Borrower
or a Lender. Agent shall not be responsible for or have any duty to ascertain or
inquire into (i) any statement, warranty or representation made in or in
connection with this Agreement or any other Loan Document, (ii) the contents of
any certificate, report or other document delivered hereunder or thereunder or
in connection herewith or therewith, (iii) the performance or observance of any
of the covenants, agreements or other terms or conditions set forth herein or
therein or the occurrence of any Default, (iv) the validity, enforceability,
effectiveness or genuineness of this Agreement, any other Loan Document or any
other agreement, instrument or document or (v) the satisfaction of any condition
set forth in Article IV or elsewhere herein, other than to confirm receipt of
items expressly required to be delivered to Agent. Notwithstanding the
foregoing, in making appropriate distributions of all funds that it receives and
is required to distribute hereunder, Agent's standard of care shall be ordinary
negligence.

      9.04 RELIANCE BY ADMINISTRATIVE AGENT. Agent shall be entitled to rely
upon, and shall not incur any liability for relying upon, any notice, request,
certificate, consent, statement, instrument, document or other writing
(including any electronic message, Internet or intranet website posting or other
distribution) believed by it to be genuine and to have been signed, sent or
otherwise authenticated by the proper Person. Agent also may rely upon any
statement made to it orally or by telephone and believed by it to have been made
by the proper Person, and shall not incur any liability for relying thereon. In
determining compliance with any condition hereunder to the making of a Loan that
by its terms must be fulfilled to the satisfaction of a Lender, Agent may
presume that such condition is satisfactory to such Lender unless Agent shall
have received notice to the contrary from such Lender prior to the making of
such Loan. Agent may consult with legal counsel (who may be counsel for
Borrower), independent accountants and other experts selected by it, and shall
not be liable for any action taken or not taken by it in accordance with the
advice of any such counsel, accountants or experts.

      9.05 DELEGATION OF DUTIES. Agent may perform any and all of its duties and
exercise its rights and powers hereunder or under any other Loan Document by or
through any one or more sub agents appointed by Agent. Agent and any such sub
agent may perform any and all of its duties and exercise its rights and powers
by or through their respective Related Parties. The exculpatory provisions of
this Article shall apply to any such sub agent and to the Related Parties

                                       62
<PAGE>

of Agent and any such sub agent, and shall apply to their respective activities
in connection with the syndication of the credit facilities provided for herein
as well as activities as Agent.

      9.06 RESIGNATION OF AGENT. Agent may at any time give notice of its
resignation to Lenders and Borrower. Upon receipt of any such notice of
resignation, the Required Lenders shall have the right, in consultation with
Borrower, to appoint a successor, which shall be a bank with an office in the
United States, or an Affiliate of any such bank with an office in the United
States. If no such successor shall have been so appointed by the Required
Lenders and shall have accepted such appointment within 30 days after the
retiring Agent gives notice of its resignation, then the retiring Agent may on
behalf of Lenders, appoint a successor Agent meeting the qualifications set
forth above; provided that if Agent shall notify the Borrower and the Lenders
that no qualifying Person has accepted such appointment, then such resignation
shall nonetheless become effective in accordance with such notice and (1) the
retiring Agent shall be discharged from its duties and obligations hereunder and
under the other Loan Documents (except that in the case of any collateral
security held by Agent on behalf of the Lenders under any of the Loan Documents,
the retiring Agent shall continue to hold such collateral security until such
time as a successor Agent is appointed) and (2) all payments, communications and
determinations provided to be made by, to or through Agent shall instead be made
by or to each Lender directly, until such time as the Required Lenders appoint a
successor Agent as provided for above in this Section. Upon the acceptance of a
successor's appointment as Agent hereunder, such successor shall succeed to and
become vested with all of the rights, powers, privileges and duties of the
retiring (or retired) Agent, and the retiring Agent shall be discharged from all
of its duties and obligations hereunder or under the other Loan Documents (if
not already discharged therefrom as provided above in this Section). The fees
payable by Borrower to a successor Agent shall be the same as those payable to
its predecessor unless otherwise agreed between Borrower and such successor.
After the retiring Agent's resignation hereunder and under the other Loan
Documents, the provisions of this Article and Section 10.04 shall continue in
effect for the benefit of such retiring Agent, its sub agents and their
respective Related Parties in respect of any actions taken or omitted to be
taken by any of them while the retiring Administrative Agent was acting as
Administrative Agent.

      9.07 NON-RELIANCE ON AGENT AND OTHER LENDERS. Each Lender acknowledges
that it has, independently and without reliance upon Agent or any other Lender
or any of their Related Parties and based on such documents and information as
it has deemed appropriate, made its own credit analysis and decision to enter
into this Agreement. Each Lender also acknowledges that it will, independently
and without reliance upon Agent or any other Lender or any of their Related
Parties and based on such documents and information as it shall from time to
time deem appropriate, continue to make its own decisions in taking or not
taking action under or based upon this Agreement, any other Loan Document or any
related agreement or any document furnished hereunder or thereunder.

      9.08 NO OTHER DUTIES, ETC. Anything herein to the contrary
notwithstanding, no Lender holding a title listed on the cover page hereof shall
have any powers, duties or responsibilities under this Agreement or any of the
other Loan Documents, except in its capacity, as applicable, as Agent or a
Lender hereunder.

      9.09 ADMINISTRATIVE AGENT MAY FILE PROOFS OF CLAIM. In case of the
pendency of any receivership, insolvency, liquidation, bankruptcy,
reorganization, arrangement, adjustment, composition or other judicial
proceeding relative to Borrower, Agent (irrespective of whether the principal of
any Loan shall then be due and payable as herein expressed or by declaration or
otherwise and irrespective of whether Agent shall have made any demand on
Borrower) shall be entitled and empowered, by intervention in such proceeding or
otherwise:

      (a) to file and prove a claim for the whole amount of the principal and
interest owing and unpaid in respect of the Loans and all other Obligations that
are owing and unpaid and to file such other documents as may be necessary or
advisable in order to have the claims of Lenders and Agent (including any claim
for the reasonable compensation, expenses, disbursements and advances of Lenders
and Agent and their respective agents and counsel and all other amounts due
Lenders and Agent under Sections 2.03(i) and 2.07 and 10.04 allowed in such
judicial proceeding; and

      (b) to collect and receive any monies or other property payable or
deliverable on any such claims and to distribute the same;

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or
other similar official in any such judicial proceeding is hereby authorized by
each Lender to make such payments to Agent and, in the event that Agent shall
consent to the making of such payments directly to Lenders, to pay to Agent any
amount due for the reasonable compensation, expenses, disbursements and advances
of Agent and its agents and counsel, and any other amounts due Agent under
Sections 2.07 and 10.04. Nothing contained herein shall be deemed to authorize
Agent to authorize or consent to or accept or adopt on behalf of any Lender any
plan of reorganization, arrangement, adjustment or composition affecting the
Obligations or the rights of any Lender or to authorize Agent to vote in respect
of the claim of any Lender in any such proceeding.

      9.10 COLLATERAL MATTERS.

      (a) Each Lender hereby irrevocably authorizes and directs Agent to enter
into the Collateral Documents for the benefit of such Lender. Each Lender hereby
agrees, and each holder of any Note by the acceptance thereof will be deemed to
agree, that, except as otherwise set forth in Section 10.01, any action taken by
the Required Lenders, in accordance with the provisions of this Agreement or the
Collateral Documents, and the exercise by the Required Lenders of the powers set
forth herein or therein, together with such other powers as are reasonably
incidental thereto, shall be authorized and binding upon all of Lenders. Agent
is hereby authorized (but not obligated) on behalf of all of Lenders, without
the necessity of any notice to or further consent from any Lender from time to
time prior to, an Event of Default, to take any action with respect to any
Collateral or Collateral Documents which may be necessary to perfect and
maintain perfected the Liens upon the Collateral granted pursuant to the
Collateral Documents.

      (b) Each Lender hereby irrevocably authorize Agent, at its option and in
its discretion,

                                       64
<PAGE>

            (i) to release any Lien on any property granted to or held by Agent
      under any Loan Document (A) upon termination of the Aggregate Commitments
      and payment in full of all Obligations (other than contingent
      indemnification obligations), (B) that is sold or to be sold as part of or
      in connection with any sale permitted hereunder or under any other Loan
      Document, (C) subject to Section 10.01, if approved, authorized or
      ratified in writing by the Required Lenders, or (D) in connection with any
      foreclosure sale or other disposition of Collateral after the occurrence
      of an Event of Default; and

            (ii) to subordinate any Lien on any property granted to or held by
      Agent under any Loan Document to the holder of any Lien on such property
      that is permitted by this Agreement or any other Loan Document.

Upon request by Agent at any time, each Lender will confirm in writing Agent's
authority to release or subordinate its interest in particular types or items of
Collateral pursuant to this Section 9.10.

      (c) Subject to (b) above, Agent shall (and is hereby irrevocably
authorized by each Lender, to execute such documents as may be necessary to
evidence the release or subordination of the Liens granted to Agent for the
benefit of Agent and Lenders herein or pursuant hereto upon the applicable
Collateral; provided that (i) Agent shall not be required to execute any such
document on terms which, in Agent's opinion, would expose Agent to or create any
liability or entail any consequence other than the release or subordination of
such Liens without recourse or warranty and (ii) such release or subordination
shall not in any manner discharge, affect or impair the Obligations or any Liens
upon (or obligations of Borrower in respect of) all interests retained by
Borrower, including the proceeds of the sale, all of which shall continue to
constitute part of the Collateral. In the event of any sale or transfer of
Collateral, or any foreclosure with respect to any of the Collateral, Agent
shall be authorized to deduct all expenses reasonably incurred by Agent from the
proceeds of any such sale, transfer or foreclosure.

      (d) Agent shall have no obligation whatsoever to any Lender or any other
Person to assure that the Collateral exists or is owned by Borrower or is cared
for, protected or insured or that the Liens granted to Agent herein or in any of
the Collateral Documents or pursuant hereto or thereto have been properly or
sufficiently or lawfully created, perfected, protected or enforced or are
entitled to any particular priority, or to exercise or to continue exercising at
all or in any manner or under any duty of care, disclosure or fidelity any of
the rights, authorities and powers granted or available to Agent in this Section
9.10 or in any of the Collateral Documents, it being understood and agreed that
in respect of the Collateral, or any act, omission or event related thereto,
Agent may act in any manner it may deem appropriate, in its sole discretion,
given Agent's own interest in the Collateral as one of the Lenders and that
Agent shall have no duty or liability whatsoever to Lenders.

      (e) Each Lender hereby appoints each other Lender as agent for the purpose
of perfecting Lenders' security interest in assets which, in accordance with
Article 9 of the UCC can be perfected only by possession. Should any Lender
(other than Agent) obtain possession of any such Collateral, such Lender shall
notify Agent thereof, and, promptly upon Agent's request therefor shall deliver
such Collateral to Agent or in accordance with Agent's instructions.

by telecopier shall be deemed to have been given when sent (except that, if not
given during normal business hours for the recipient, shall be deemed to have
been given at the opening of business on the next business day for the
recipient). Notices delivered through electronic communications to the extent
provided in subsection (b) below, shall be effective as provided in such
subsection (b).

                                       67

      (b) Electronic Communications. Notices and other communications to Lenders
hereunder may be delivered or furnished by electronic communication (including
e-mail and Internet or intranet websites) pursuant to procedures approved by
Agent, provided that the foregoing shall not apply to notices to any Lender
pursuant to Article II if such Lender has notified the Agent that it is
incapable of receiving notices under such Article by electronic communication.
Agent or Borrower may, in its discretion, agree to accept notices and other
communications to it hereunder by electronic communications pursuant to
procedures approved by it, provided that approval of such procedures may be
limited to particular notices or communications. Unless Agent otherwise
prescribes, (i) notices and other communications sent to an e-mail address shall
be deemed received upon the sender's receipt of an acknowledgement from the
intended recipient (such as by the "return receipt requested" function, as
available, return e-mail or other written acknowledgement), provided that if
such notice or other communication is not sent during the normal business hours
of the recipient, such notice or communication shall be deemed to have been sent
at the opening of business on the next business day for the recipient, and (ii)
notices or communications posted to an Internet or intranet website shall be
deemed received upon the deemed receipt by the intended recipient at its e-mail
address as described in the foregoing clause (i) of notification that such
notice or communication is available and identifying the website address
therefor.

      (c) The Platform. THE PLATFORM IS PROVIDED "AS IS" AND "AS AVAILABLE." THE
AGENT PARTIES (AS DEFINED BELOW) DO NOT WARRANT THE ACCURACY OR COMPLETENESS OF
THE BORROWER MATERIALS OR THE ADEQUACY OF THE PLATFORM, AND EXPRESSLY DISCLAIM
LIABILITY FOR ERRORS IN OR OMISSIONS FROM THE BORROWER MATERIALS. NO WARRANTY OF
ANY KIND, EXPRESS, IMPLIED OR STATUTORY, INCLUDING ANY WARRANTY OF
MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT OF THIRD
PARTY RIGHTS OR FREEDOM FROM VIRUSES OR OTHER CODE DEFECTS, IS MADE BY ANY AGENT
PARTY IN CONNECTION WITH THE BORROWER MATERIALS OR THE PLATFORM. In no event
shall the Administrative Agent or any of its Related Parties (collectively, the
"Agent Parties") have any liability to the Borrower, any Lender or any other
Person for losses, claims, damages, liabilities or expenses of any kind (whether
in tort, contract or otherwise) arising out of the Borrower's or the
Administrative Agent's transmission of Borrower Materials through the Internet,
except to the extent that such losses, claims, damages, liabilities or expenses
are determined by a court of competent jurisdiction by a final and nonappealable
judgment to have resulted from the gross negligence or willful misconduct of
such Agent Party; provided, however, that in no event shall any Agent Party have
any liability to the Borrower, any Lender or any other Person for indirect,
special, incidental, consequential or punitive damages (as opposed to direct or
actual damages).

      (d) Change of Address, Etc. Each of the Borrower and Agent may change its
address, telecopier or telephone number for notices and other communications
hereunder by notice to the other parties hereto. Each other Lender may change
its address, telecopier or telephone number for notices and other communications
hereunder by notice to Borrower and Agent. In addition, each Lender agrees to
notify the Administrative Agent from time to time to ensure that the
Administrative Agent has on record (i) an effective address, contact name,

                                       68
<PAGE>

telephone number, telecopier number and electronic mail address to which notices
and other communications may be sent and (ii) accurate wire instructions for
such Lender.

      (e) Reliance by Agent and Lenders. Agent and Lenders shall be entitled to
rely and act upon any notices (including telephonic Loan Notices) purportedly
given by or on behalf of Borrower even if (i) such notices were not made in a
manner specified herein, were incomplete or were not preceded or followed by any
other form of notice specified herein, or (ii) the terms thereof, as understood
by the recipient, varied from any confirmation thereof. Borrower shall indemnify
Agent, each Lender and the Related Parties of each of them from all losses,
costs, expenses and liabilities resulting from the reliance by such Person on
each notice purportedly given by or on behalf of Borrower. All telephonic
notices to and other telephonic communications with Agent may be recorded by
Agent, and each of the parties hereto hereby consents to such recording.

      10.03 NO WAIVER; CUMULATIVE REMEDIES. No failure by any Lender or Agent to
exercise, and no delay by any such Person in exercising, any right, remedy,
power or privilege under any Loan Documents shall operate as a waiver thereof;
nor shall any single or partial exercise of any right, remedy, power or
privilege hereunder preclude any other or further exercise thereof or the
exercise of any other right, remedy, power or privilege. The rights, remedies,
powers and privileges provided in any Loan Documents are cumulative and not
exclusive of any rights, remedies, powers and privileges provided by law.

      10.04 EXPENSES; INDEMNITY; DAMAGE WAIVER.

      (a) Costs and Expenses. Borrower shall pay (i) all reasonable out of
pocket expenses incurred by Agent and its Affiliates (including the reasonable
fees, charges and disbursements of counsel for Agent), in connection with the
syndication of the credit facilities provided for herein, the preparation,
negotiation, execution, delivery and administration of this Agreement and the
other Loan Documents or any amendments, modifications or waivers of the
provisions hereof or thereof (whether or not the transactions contemplated
hereby or thereby shall be consummated) and (ii) all out of pocket expenses
incurred by Agent or any Lender (including the fees, charges and disbursements
of any counsel for Agent or any Lender) in connection with the enforcement or
protection of its rights (A) in connection with this Agreement and the other
Loan Documents, including its rights under this Section, or (B) in connection
with the Loans made hereunder, including all such out of pocket expenses
incurred during any workout, restructuring or negotiations in respect of such
Loans.

      (b) Indemnification by the Borrower. Borrower shall indemnify Agent (and
any sub-agent thereof), each Lender, and each Related Party of any of the
foregoing Persons (each such Person being called an "Indemnitee") against, and
hold each Indemnitee harmless from, any and all losses, claims, damages,
liabilities and related expenses (including the fees, charges and disbursements
of any counsel for any Indemnitee), incurred by any Indemnitee or asserted
against any Indemnitee by any third party or by Borrower arising out of, in
connection with, or as a result of (i) the execution or delivery of this
Agreement, any other Loan Document or any agreement or instrument contemplated
hereby or thereby, the performance by the parties hereto of their respective
obligations hereunder or thereunder or the consummation of the transactions
contemplated hereby or thereby, or, in the case of the Administrative Agent (and
any sub-agent

                                       69
<PAGE>

thereof) and its Related Parties only, the administration of this Agreement and
the other Loan Documents, (ii) any Loan or the use or proposed use of the
proceeds therefrom, (iii) any actual or alleged presence or release of Hazardous
Materials on or from any property owned or operated by the Borrower or any of
its Subsidiaries, or any Environmental Liability related in any way to the
Borrower or any of its Subsidiaries, or (iv) any actual or prospective claim,
litigation, investigation or proceeding relating to any of the foregoing,
whether based on contract, tort or any other theory, whether brought by a third
party or by the Borrower, and regardless of whether any Indemnitee is a party
thereto, in all cases, whether or not caused by or arising, in whole or in part,
out of the comparative or contributory (but not sole) negligence of the
Indemnitee; provided that such indemnity shall not, as to any Indemnitee, be
available to the extent that such losses, claims, damages, liabilities or
related expenses (x) are determined by a court of competent jurisdiction by
final and nonappealable judgment to have resulted from the gross negligence or
willful misconduct of such Indemnitee or (y) result from a claim brought by
Borrower against an Indemnitee for breach in bad faith of such Indemnitee's
obligations hereunder or under any other Loan Document, if Borrower has obtained
a final and nonappealable judgment in its favor on such claim as determined by a
court of competent jurisdiction or (z) result from Agent's negligence in making
appropriate distributions of funds that Agent receives and is required to
distribute hereunder.

      (c) Reimbursement by Lenders. To the extent that Borrower for any reason
fails to indefeasibly pay any amount required under subsection (a) or (b) of
this Section to be paid by it to Agent (or any sub-agent thereof) or any Related
Party of any of the foregoing, each Lender severally agrees to pay to Agent (or
any such sub-agent) or such Related Party, as the case may be, such Lender's
Applicable Percentage (determined as of the time that the applicable
unreimbursed expense or indemnity payment is sought) of such unpaid amount,
provided that the unreimbursed expense or indemnified loss, claim, damage,
liability or related expense, as the case may be, was incurred by or asserted
against Agent (or any such sub-agent) or against any Related Party of any of the
foregoing acting for Agent (or any such sub-agent). The obligations of the
Lenders under this subsection (c) are subject to the provisions of Section
2.10(d).

      (d) Waiver of Consequential Damages, Etc. To the fullest extent permitted
by applicable law, Borrower shall not assert, and hereby waives, any claim
against any Indemnitee, on any theory of liability, for special, indirect,
consequential or punitive damages (as opposed to direct or actual damages)
arising out of, in connection with, or as a result of, this Agreement, any other
Loan Document or any agreement or instrument contemplated hereby, the
transactions contemplated hereby or thereby, any Loan or the use of the proceeds
thereof. No Indemnitee referred to in subsection (b) above shall be liable for
any damages arising from the use by unintended recipients of any information or
other materials distributed by it through telecommunications, electronic or
other information transmission systems in connection with this Agreement or the
other Loan Documents or the transactions contemplated hereby or thereby.

      (e) Payments. All amounts due under this Section shall be payable not
later than 30 Business Days after demand therefor, provided that such demand is
supported by a statement showing. in reasonable detail, the basis for the amount
demanded including the method of calculating such amount, if applicable.

                                       70
<PAGE>

      (f) Survival. The agreements in this Section shall survive the resignation
of Agent, the replacement of any Lender, the termination of the Aggregate
Commitments and the repayment, satisfaction or discharge of all the other
Obligations.

      10.05 PAYMENTS SET ASIDE. To the extent that any payment by or on behalf
of Borrower is made to Agent or any Lender, or Agent or any Lender exercises its
right of setoff, and such payment or the proceeds of such setoff or any part
thereof is subsequently invalidated, declared to be fraudulent or preferential,
set aside or required (including pursuant to any settlement entered into by
Agent or such Lender in its discretion) to be repaid to a trustee, receiver or
any other party, in connection with any proceeding under any Debtor Relief Law
or otherwise, then (a) to the extent of such recovery, the obligation or part
thereof originally intended to be satisfied shall be revived and continued in
full force and effect as if such payment had not been made or such setoff had
not occurred, and (b) each Lender severally agrees to pay to Agent upon demand
its applicable share (without duplication) of any amount so recovered from or
repaid by Agent, plus interest thereon from the date of such demand to the date
such payment is made at a rate per annum equal to the Federal Funds Rate from
time to time in effect. The obligations of the Lenders under clause (b) of the
preceding sentence shall survive the payment in full of the Obligations and the
termination of this Agreement.

      10.06 SUCCESSORS AND ASSIGNS.

      (a) Successors and Assigns Generally. The provisions of this Agreement and
each other Loan Document shall be binding upon and inure to the benefit of the
parties hereto and their respective successors and assigns permitted hereby,
except that Borrower may not assign or otherwise transfer any of its rights or
obligations hereunder without the prior written consent of Agent and each Lender
and no Lender may assign or otherwise transfer any of its rights or obligations
hereunder except (i) to an Eligible Assignee in accordance with the provisions
of subsection (b) of this Section, (ii) by way of participation in accordance
with the provisions of subsection (d) of this Section, or (iii) by way of pledge
or assignment of a security interest subject to the restrictions of subsection
(f) of this Section (and any other attempted assignment or transfer by any party
hereto shall be null and void); or (iv) to an SPC in accordance with the
provisions of subsection (h) of this Section. Nothing in this Agreement,
expressed or implied, shall be construed to confer upon any Person (other than
the parties hereto, their respective successors and assigns permitted hereby,
Participants to the extent provided in subsection (d) of this Section and, to
the extent expressly contemplated hereby, the Related Parties of each of Agent
and the Lenders) any legal or equitable right, remedy or claim under or by
reason of this Agreement.

      (b) Assignments by Lenders. Any Lender may at any time assign to one or
more Eligible Assignees all or a portion of its rights and obligations under
this Agreement (including all or a portion of its Commitment and the Loans at
the time owing to it); provided that (i) except in the case of an assignment of
the entire remaining amount of the assigning Lender's Commitment and the Loans
at the time owing to it or in the case of an assignment to a Lender or an
Affiliate of a Lender or an Approved Fund with respect to a Lender, the
aggregate amount of the Commitment (which for this purpose includes Loans
outstanding thereunder) or, if the Commitment is not then in effect, the
principal outstanding balance of the Loans of the assigning Lender subject to
each such assignment, determined as of the date the Assignment and

                                       71
<PAGE>

Assumption with respect to such assignment is delivered to Agent or, if "Trade
Date" is specified in the Assignment and Assumption, as of the Trade Date, shall
not be less than $1,000,000 unless each of Agent and, so long as no Event of
Default has occurred and is continuing, Borrower otherwise consents (each such
consent not to be unreasonably withheld or delayed); provided, however, that
concurrent assignments to members of an Assignee Group and concurrent
assignments from members of an Assignee Group to a single Eligible Assignee (or
to an Eligible Assignee and members of its Assignee Group) will be treated as a
single assignment for purposes of determining whether such minimum amount has
been met; (ii) each partial assignment shall be made as an assignment of a
proportionate part of all the assigning Lender's rights and obligations under
this Agreement with respect to the Loans or the Commitment assigned; (iii) any
assignment of a Commitment must be approved by Agent unless the Person that is
the proposed assignee is itself a Lender (whether or not the proposed assignee
would otherwise qualify as an Eligible Assignee); and (iv) the parties to each
assignment shall execute and deliver to Agent an Assignment and Assumption,
together with a processing and recordation fee in the amount, if any, required
as set forth in Schedule 10.06, payable by the assigning Lender and the Eligible
Assignee, if it shall not be a Lender, shall deliver to Agent an Administrative
Questionnaire. Subject to acceptance and recording thereof by Agent pursuant to
subsection (c) of this Section, from and after the effective date specified in
each Assignment and Assumption, the Eligible Assignee thereunder shall be a
party to this Agreement and, to the extent of the interest assigned by such
Assignment and Assumption, have the rights and obligations of a Lender under
this Agreement, and the assigning Lender thereunder shall, to the extent of the
interest assigned by such Assignment and Assumption, be released from its
obligations under this Agreement (and, in the case of an Assignment and
Assumption covering all of the assigning Lender's rights and obligations under
this Agreement, such Lender shall cease to be a party hereto) but shall continue
to be entitled to the benefits of Sections 3.01, 3.04, 3.05, and 10.04 with
respect to facts and circumstances occurring prior to the effective date of such
assignment. Upon request, Borrower (at its expense) shall execute and deliver a
Note to the assignee Lender. Any assignment or transfer by a Lender of rights or
obligations under this Agreement that does not comply with this subsection shall
be treated for purposes of this Agreement as a sale by such Lender of a
participation in such rights and obligations in accordance with subsection (d)
of this Section.

      (c) Register. Agent, acting solely for this purpose as an agent of
Borrower, shall maintain at Administrative Agent's Office a copy of each
Assignment and Assumption delivered to it and a register for the recordation of
the names and addresses of the Lenders, and the Commitments of, and principal
amounts of the Loans owing to, each Lender pursuant to the terms hereof from
time to time (the "Register"). The entries in the Register shall be conclusive,
and Borrower, Agent and the Lenders may treat each Person whose name is recorded
in the Register pursuant to the terms hereof as a Lender hereunder for all
purposes of this Agreement, notwithstanding notice to the contrary. The Register
shall be available for inspection by each of Borrower at any reasonable time and
from time to time upon reasonable prior notice. In addition, at any time that a
request for a consent for a material or substantive change to the Loan Documents
is pending, any Lender wishing to consult with other Lenders in connection
therewith may request and receive from Agent a copy of the Register.

                                       72
<PAGE>

      (d) Participations. Any Lender may at any time, without the consent of, or
notice to, Borrower or Agent, sell participations to any Person (other than a
natural person or Borrower or any of Borrower's Affiliates or Subsidiaries)
(each, a "Participant") in all or a portion of such Lender's rights and/or
obligations under this Agreement (including all or a portion of its Commitment
and/or the Loans owing to it); provided that (i) such 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
and (iii) Borrower, Agent and the Lenders shall continue to deal solely and
directly with such Lender in connection with such Lender's rights and
obligations under this Agreement. Any agreement or instrument pursuant to which
a Lender sells such a participation shall provide that such Lender shall retain
the sole right to enforce this Agreement and to approve any amendment,
modification or waiver of any provision of this Agreement; provided that such
agreement or instrument may provide that such Lender will not, without the
consent of the Participant, agree to any amendment, waiver or other modification
described in the first proviso to Section 10.01 that affects such Participant.
Subject to subsection (e) of this Section, Borrower agrees that each Participant
shall be entitled to the benefits of Sections 3.01, 3.04 and 3.05 to the same
extent as if it were a Lender and had acquired its interest by assignment
pursuant to subsection (b) of this Section. To the extent permitted by law, each
Participant also shall be entitled to the benefits of Section 10.08 as though it
were a Lender, provided such Participant agrees to be subject to Section 2.11 as
though it were a Lender.

      (e) Limitations upon Participant Rights. A Participant shall not be
entitled to receive any greater payment under Section 3.01 or 3.04 than the
applicable Lender would have been entitled to receive with respect to the
participation sold to such Participant, unless the sale of the participation to
such Participant is made with Borrower's prior written consent. A Participant
that would be a Foreign Lender if it were a Lender shall not be entitled to the
benefits of Section 3.01 unless the Borrower is notified of the participation
sold to such Participant and such Participant agrees, for the benefit of the
Borrower, to comply with Section 3.01(e) as though it were a Lender.

      (f) Certain Pledges. Any Lender may at any time pledge or assign a
security interest in all or any portion of its rights under this Agreement
(including under its Note, if any) to secure obligations of such Lender,
including any pledge or assignment to secure obligations to a Federal Reserve
Bank; provided that no such pledge or assignment shall release such Lender from
any of its obligations hereunder or substitute any such pledgee or assignee for
such Lender as a party hereto.

      (g) Electronic Execution of Assignments. The words "execution," "signed,"
"signature," and words of like import in any Assignment and Assumption shall be
deemed to include electronic signatures or the keeping of records in electronic
form, each of which shall be of the same legal effect, validity or
enforceability as a manually executed signature or the use of a paper-based
recordkeeping system, as the case may be, to the extent and as provided for in
any applicable law, including the Federal Electronic Signatures in Global and
National Commerce Act, the New York State Electronic Signatures and Records Act,
or any other similar state laws based on the Uniform Electronic Transactions
Act.

                                       73
<PAGE>

      (h) Deemed Consent of Borrower. If the consent of Borrower to an
assignment to an Eligible Assignee is required hereunder (including a consent to
an assignment which does not meet the minimum assignment threshold specified in
clause (i) of the proviso to the first sentence of Section 10.06(b)), Borrower
shall be deemed to have given its consent ten Business Days after the date
notice thereof has been delivered to Borrower by the assigning Lender (through
Agent) unless such consent is expressly refused by Borrower prior to such tenth
Business Day.

      (i) Special Purpose Funding Vehicles. Notwithstanding anything to the
contrary contained herein, any Lender (a "Granting Lender") may grant to a
special purpose funding vehicle identified as such in writing from time to time
by the Granting Lender to the Administrative Agent and the Borrower (an "SPC")
the option to provide all or any part of any Committed Loan that such Granting
Lender would otherwise be obligated to make pursuant to this Agreement; provided
that (i) nothing herein shall constitute a commitment by any SPC to fund any
Committed Loan, and (ii) if an SPC elects not to exercise such option or
otherwise fails to make all or any part of such Committed Loan, the Granting
Lender shall be obligated to make such Committed Loan pursuant to the terms
hereof or, if it fails to do so, to make such payment to the Administrative
Agent as is required under Section 2.12(b)(ii). Each party hereto hereby agrees
that (i) neither the grant to any SPC nor the exercise by any SPC of such option
shall increase the costs or expenses or otherwise increase or change the
obligations of the Borrower under this Agreement (including its obligations
under Section 3.04), (ii) no SPC shall be liable for any indemnity or similar
payment obligation under this Agreement for which a Lender would be liable, and
(iii) the Granting Lender shall for all purposes, including the approval of any
amendment, waiver or other modification of any provision of any Loan Document,
remain the lender of record hereunder. The making of a Committed Loan by an SPC
hereunder shall utilize the Commitment of the Granting Lender to the same
extent, and as if, such Committed Loan were made by such Granting Lender. In
furtherance of the foregoing, each party hereto hereby agrees (which agreement
shall survive the termination of this Agreement) that, prior to the date that is
one year and one day after the payment in full of all outstanding commercial
paper or other senior debt of any SPC, it will not institute against, or join
any other Person in instituting against, such SPC any bankruptcy,
reorganization, arrangement, insolvency, or liquidation proceeding under the
laws of the United States or any State thereof. Notwithstanding anything to the
contrary contained herein, any SPC may (i) with notice to, but without prior
consent of the Borrower and the Administrative Agent and with the payment of a
processing fee in the amount of $2,500, assign all or any portion of its right
to receive payment with respect to any Committed Loan to the Granting Lender and
(ii) disclose on a confidential basis any non-public information relating to its
funding of Committed Loans to any rating agency, commercial paper dealer or
provider of any surety or guarantee or credit or liquidity enhancement to such
SPC.

      10.07 TREATMENT OF CERTAIN INFORMATION; CONFIDENTIALITY. Each of Agent and
Lenders agrees to maintain the confidentiality of the Information (as defined
below), except that Information may be disclosed (a) to its Affiliates and to
its and its Affiliates' respective partners, directors, officers, employees,
agents, advisors and representatives (it being understood that the Persons to
whom such disclosure is made will be informed of the confidential nature of such
Information and instructed to keep such Information confidential), (b) to the
extent requested by any regulatory authority, purporting to have jurisdiction
over it (including any self-regulatory authority, such as the National
Association of Insurance Commissioners), (c) to the extent

                                       74
<PAGE>

required by applicable laws or regulations or by any subpoena or similar legal
process (but in the case of a subpoena or similar legal process, only to the
extent responsive thereto), (d) to any other party hereto, (e) in connection
with the exercise of any remedies hereunder or under any other Loan Document or
any action or proceeding relating to this Agreement or any other Loan Document
or the enforcement of rights hereunder or thereunder, (f) subject to an
agreement containing provisions substantially the same as those of this Section,
to (i) any assignee of or Participant in, or any prospective assignee of or
Participant in, any of its rights or obligations under this Agreement or (ii)
any actual or prospective counterparty (or its advisors) to any swap or
derivative transaction relating to Borrower and its obligations, (g) with the
consent of Borrower or (h) to the extent such Information (x) becomes publicly
available other than as a result of a breach of this Section or (y) becomes
available to Agent or any Lender or any of their respective Affiliates on a
nonconfidential basis from a source other than Borrower. For purposes of this
Section, "Information" means all information received from Borrower or any
Subsidiary relating to Borrower or any Subsidiary or any of their respective
businesses, other than any such information that is available to Agent or any
Lender on a nonconfidential basis prior to disclosure by Borrower or any
Subsidiary, provided that, in the case of information received from Borrower or
any Subsidiary after the date hereof, such information is clearly identified at
the time of delivery as confidential. Any Person required to maintain the
confidentiality of Information as provided in this Section shall be considered
to have complied with its obligation to do so if such Person has exercised the
same degree of care to maintain the confidentiality of such Information as such
Person would accord to its own confidential information.

      10.08 RIGHT OF SETOFF. If an Event of Default shall have occurred and be
continuing, each Lender and each of their respective Affiliates is hereby
authorized at any time and from time to time, to the fullest extent permitted by
applicable law, to set off and apply any and all deposits (general or special,
time or demand, provisional or final, in whatever currency) at any time held and
other obligations (in whatever currency) at any time owing by such Lender or any
such Affiliate to or for the credit or the account of Borrower against any and
all of the obligations of Borrower now or hereafter existing under this
Agreement or any other Loan Document to such Lender or any such Affiliate,
irrespective of whether or not such Lender shall have made any demand under this
Agreement or any other Loan Document and although such obligations of Borrower
may be contingent or unmatured or are owed to a branch or office of such Lender
different from the branch or office holding such deposit or obligated on such
indebtedness. The rights of each Lender and their respective Affiliates under
this Section are in addition to other rights and remedies (including other
rights of setoff) that such Lender or their respective Affiliates may have. Each
Lender agrees to notify Borrower and Agent promptly after any such setoff and
application, provided that the failure to give such notice shall not affect the
validity of such setoff and application.

      10.09 INTEREST RATE LIMITATION. Notwithstanding anything to the contrary
contained in any Loan Document, the interest paid or agreed to be paid under the
Loan Documents shall not exceed the maximum rate of non-usurious interest
permitted by applicable Law (the "Maximum Rate"). If Agent or any Lender shall
receive interest in an amount that exceeds the Maximum Rate, the excess interest
shall be applied to the principal of the Loans or, if it exceeds such unpaid
principal, refunded to Borrower. In determining whether the interest contracted
for, charged, or received by Agent or a Lender exceeds the Maximum Rate, such
Person may, to the

                                       75
<PAGE>

extent permitted by applicable Law, (a) characterize any payment that is not
principal as an expense, fee, or premium rather than interest, (b) exclude
voluntary prepayments and the effects thereof, and (c) amortize, prorate,
allocate, and spread in equal or unequal parts the total amount of interest
throughout the contemplated term of the Obligations hereunder.

      10.10 COUNTERPARTS; INTEGRATION; EFFECTIVENESS. This Agreement may be
executed in counterparts (and by different parties hereto in different
counterparts), each of which shall constitute an original, but all of which when
taken together shall constitute a single contract. This Agreement and the other
Loan Documents constitute the entire contract among the parties relating to the
subject matter hereof and supersede any and all previous agreements and
understandings, oral or written, relating to the subject matter hereof. Except
as provided in Section 4.01, this Agreement shall become effective when it shall
have been executed by Agent and when Agent shall have received counterparts
hereof that, when taken together, bear the signatures of each of the other
parties hereto. Delivery of an executed counterpart of a signature page of this
Agreement by telecopy shall be effective as delivery of a manually executed
counterpart of this Agreement.

      10.11 SURVIVAL OF REPRESENTATIONS AND WARRANTIES. All representations and
warranties made hereunder and in any other Loan Document or other document
delivered pursuant hereto or thereto or in connection herewith or therewith
shall survive the execution and delivery hereof and thereof. Such
representations and warranties have been or will be relied upon by Agent and
each Lender, regardless of any investigation made by Agent or any Lender or on
their behalf and notwithstanding that Agent or any Lender may have had notice or
knowledge of any Default at the time of any Borrowing, and shall continue in
full force and effect as long as any Loan or any other Obligation hereunder
shall remain unpaid or unsatisfied.

      10.12 SEVERABILITY. If any provision of this Agreement or the other Loan
Documents is held to be illegal, invalid or unenforceable, (a) the legality,
validity and enforceability of the remaining provisions of this Agreement and
the other Loan Documents shall not be affected or impaired thereby and (b) the
parties shall endeavor in good faith negotiations to replace the illegal,
invalid or unenforceable provisions with valid provisions the economic effect of
which comes as close as possible to that of the illegal, invalid or
unenforceable provisions. The invalidity of a provision in a particular
jurisdiction shall not invalidate or render unenforceable such provision in any
other jurisdiction.

      10.13 REPLACEMENT OF LENDERS. If any Lender requests compensation under
Section 3.04, or if the Borrower is required to pay any additional amount to any
Lender or any Governmental Authority for the account of any Lender pursuant to
Section 3.01, or if any Lender is a Defaulting Lender, then the Borrower may, at
its sole expense and effort, upon notice to such Lender and the Administrative
Agent, require such Lender to assign and delegate, without recourse (in
accordance with and subject to the restrictions contained in, and consents
required by, Section 10.06), all of its interests, rights and obligations under
this Agreement and the related Loan Documents to an assignee that shall assume
such obligations (which assignee may be another Lender, if a Lender accepts such
assignment), provided that:

      (a) the Borrower shall have paid to the Administrative Agent the
assignment fee specified in Section 10.06(b);

                                       76
<PAGE>

      (b) such Lender shall have received payment of an amount equal to the
outstanding principal of its Loans, accrued interest thereon, accrued fees and
all other amounts payable to it hereunder and under the other Loan Documents
(including any amounts under Section 3.05) from the assignee (to the extent of
such outstanding principal and accrued interest and fees) or the Borrower (in
the case of all other amounts);

      (c) in the case of any such assignment resulting from a claim for
compensation under Section 3.04 or payments required to be made pursuant to
Section 3.01, such assignment will result in a reduction in such compensation or
payments thereafter; and

      (d) such assignment does not conflict with applicable Laws.

A Lender shall not be required to make any such assignment or delegation if,
prior thereto, as a result of a waiver by such Lender or otherwise, the
circumstances entitling the Borrower to require such assignment and delegation
cease to apply.

      10.14 GOVERNING LAW; JURISDICTION; ETC.

      (a) GOVERNING LAW. THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN
ACCORDANCE WITH, THE LAW OF THE STATE OF WASHINGTON.

ANY OTHER LOAN DOCUMENT SHALL AFFECT ANY RIGHT THAT AGENT OR ANY LENDER MAY
OTHERWISE HAVE TO BRING ANY ACTION OR PROCEEDING RELATING TO THIS AGREEMENT OR
ANY OTHER LOAN DOCUMENT AGAINST THE BORROWER OR ITS PROPERTIES IN THE COURTS OF
ANY JURISDICTION.

      (c) WAIVER OF VENUE. THE BORROWER IRREVOCABLY AND UNCONDITIONALLY WAIVES,
TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY OBJECTION THAT IT MAY NOW
OR HEREAFTER HAVE TO THE LAYING OF VENUE OF ANY ACTION OR PROCEEDING ARISING OUT
OF OR

                                       77

INCONVENIENT FORUM TO THE MAINTENANCE OF SUCH ACTION OR PROCEEDING IN ANY SUCH

AGREEMENT WILL AFFECT THE RIGHT OF ANY PARTY HERETO TO SERVE PROCESS IN ANY

ARISING OUT OF OR RELATING TO THIS AGREEMENT OR ANY OTHER LOAN DOCUMENT OR THE
TRANSACTIONS CONTEMPLATED HEREBY OR THEREBY (WHETHER BASED ON CONTRACT, TORT OR
ANY OTHER THEORY). EACH PARTY HERETO (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT
OR ATTORNEY OF ANY OTHER PERSON HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT
SUCH OTHER PERSON WOULD NOT, IN THE EVENT OF LITIGATION, SEEK TO ENFORCE THE
FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE
BEEN INDUCED TO ENTER INTO THIS AGREEMENT AND THE OTHER LOAN DOCUMENTS BY, AMONG
OTHER THINGS, THE MUTUAL WAIVERS AND CERTIFICATIONS IN THIS SECTION.

      10.16 USA PATRIOT ACT NOTICE. Each Lender that is subject to the Act (as
hereinafter defined) and Agent (for itself and not on behalf of any Lender)
hereby notifies Borrower that pursuant to the requirements of the USA Patriot
Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)) (the
"Act"), it is required to obtain, verify and record information that identifies
Borrower, which information includes the name and address of Borrower and other

Mortgage Property without release or interruption notwithstanding the

herein provided to be held and applied under this Section 2, so long as no Event
of Default shall have occurred and is continuing, and all monies, if any,

provided, however, that any proceeds of insurance on the Mortgaged Property not
constituting an Event of Loss of the Aircraft shall be applied as provided in
Section 2.2. All such sums shall be invested for the benefit of the Mortgagor in
investments selected by the Mortgagor.

      2.2 Insurance Proceeds Used for Repair. (a) Provided that an Event of
Default shall not have occurred and be continuing, to the extent that any Cash
Collateral is the proceeds of insurance upon any part of the Mortgaged Property,
the same may be withdrawn by the Mortgagor and shall be paid by the Mortgagee,
upon Mortgagor Order, to reimburse the Mortgagor for, and up to an amount not
exceeding, expenditures made to repair or restore the property damaged as
required hereunder, and with respect to an Event of Loss of any Engine
expenditures made to replace such Engine, but only upon receipt by the Mortgagee
of (1) a Mortgagor Request for the withdrawal and payment of specified proceeds
of insurance then included in the Cash Collateral, and (2) a Mortgagor's
Certificate, dated not more than five (5) days prior to the application for such
withdrawal, stating that expenditures have been made by the Mortgagor in a
specified amount for one or more of the purposes aforesaid, which shall be
briefly described, and also stating that no part of such expenditures has been
or is then being used in any other previous or then pending application, as the
basis for the withdrawal of any Cash Collateral from the Mortgagee hereunder.
Each such Mortgagor's Certificate shall have attached thereto photocopies of any
work-sheets, invoices, vouchers and/or receipts with respect to the repair,
restoration or replacement in question. Notwithstanding the foregoing and
provided that an Event of Default shall not have occurred and be continuing, if
Mortgagor provides Mortgagee with a written estimate (together with a
Mortgagor's Certificate certifying such estimate is genuine and complete) of any
repairs or restoration to be made with respect to such property damaged,
Mortgagor may direct that the Cash Collateral be withdrawn and paid directly to
the entity performing the repairs and be applied towards payment for such
repairs or restoration.

the Mortgagor any insurance proceeds previously paid to Mortgagee which shall
exceed the amount actually spent by the Mortgagor to effect repairs or to

of Loss of an Aircraft, such insurance proceeds which shall exceed the Current
Market Value of the Aircraft that suffered an Event of Loss, provided that in

of the Flight Equipment, free and clear of all Liens except for Permitted Liens.

            (c) The Mortgagor hereby does and will forever warrant and defend

demands of all persons whomsoever except claims and demands under the Permitted
Liens, and at all times keep the Lien granted herein with respect to the
Mortgaged Property, at the Mortgagor's expense, a first priority Lien upon the

every Security Agreement Supplement and such other instruments from time to time
as may be reasonably requested by the Mortgagee in all such jurisdictions and
offices as the Mortgagee shall from time to time reasonably require, in order
that (i) the Lien hereof as a first priority Lien on the Flight Equipment and on
all of the Mortgaged Property, (ii) the security for all of the Obligations, and
(iii) the rights and remedies of the Mortgagee, may be established, confirmed,
maintained and protected. The Mortgagor will furnish to the Mortgagee evidence
reasonably satisfactory to the Mortgagee of every such recording, registering
and filing which is not recorded, registered and filed by Mortgagee.

payable, all taxes, assessments and governmental charges lawfully levied or
assessed or imposed upon the Lien of the Mortgagee so that the Lien created by
this Security Agreement shall at all times be wholly preserved at the cost of
the Mortgagor and without expense to the Mortgagee, and the Mortgagor will not
suffer any other matter or thing whatsoever whereby the Lien created by this
Security Agreement will be impaired.

      3.4 Maintain Flight Equipment.

            (a) The Mortgagor shall, at all such times, maintain, preserve and
keep, at its own cost and expense, the Flight Equipment in good order and repair
in accordance with the Maintenance Program or cause the Flight Equipment to be
so maintained, preserved and kept without cost or expense under this Security
Agreement to the Mortgagee, except when (i) the Flight Equipment is being
temporarily stored in accordance with the Maintenance Program, (ii) the Flight
Equipment is being serviced, repaired, maintained, overhauled, tested or
modified as permitted or required by the terms of this Security Agreement or the
Credit Agreement, (iii) all similar aircraft of comparable vintage and/or
configuration have been grounded by the FAA or under the applicable laws of any
other jurisdiction in which an Aircraft is registered, or (iv) laws or
regulations affecting airworthiness are being contested in good faith and by
appropriate proceedings so long as such proceedings could not adversely affect
the Mortgagee or its interest in the affected Aircraft. Subject to the forgoing
exceptions, Mortgagor shall:

                  (i) service, repair, maintain, overhaul, test, or cause the
same to be done to the Aircraft so as to keep the Aircraft in as good operating
condition as when this Security Agreement was executed, ordinary wear and tear
excepted, in accordance with the Maintenance Program and as may be necessary to
enable the United States airworthiness certification of the Aircraft to be
maintained in good standing at all times under FAA regulations and the
applicable laws of the United States Government;

                  (ii) perform all routine and non-routine services, checks,
inspections, including any structural inspection required by the Maintenance
Program or the FAA;

                  (iii) maintain all records, logs, and other materials required
by applicable law of any governmental entity to be maintained in respect to the
Aircraft, including, but not limited to, serviceable component tags required by
the FAA;

                  (iv) upon request, for so long as any part of the Flight
Equipment is subject to the Lien of this Security Agreement, provide Mortgagee
with such information as it

                                       10
<PAGE>

shall reasonably request with respect to the scheduled commencement date of each
annual check (or the equivalent) to be performed on the Aircraft and the
location where such checks will be performed;

                  (v) incorporate in the Aircraft prior to the terminating or
compliance date all applicable airworthiness directives issued by the FAA;

                  (vii) incorporate in the Aircraft corrosion prevention and
control and correct any discrepancies in accordance with the Maintenance
Program;

                  (vi) properly document all repairs, modifications and
alterations and the addition, removal or replacement of equipment, systems or
components in accordance with the rules and regulations of the FAA and reflect
such items in the Aircraft Documentation.

      All maintenance of the Aircraft and Engines shall be performed by an
Authorized Maintenance Performer.

            (b) For so long as any part of the Flight Equipment is subject to
the Lien of this Security Agreement, the Mortgager shall maintain or cause the
Flight Equipment to be maintained in accordance with the Maintenance Program.

            (c) The Mortgagor shall promptly notify the Mortgagee or cause the
Mortgagee to be notified of any Engine becoming expropriated, worn out, lost,
destroyed or rendered unfit for use or of any other maintenance or repair of the
Flight Equipment having a projected replacement or repair cost of more than Five
Million Dollars ($5,000,000), and the Mortgagor shall furnish or cause to be
furnished to the Mortgagee a report describing in reasonable detail such items
and the items replaced by such work. In the case of an Event of Loss to an
Engine not involving an Event of Loss to the Aircraft, the Mortgagor shall,
within ninety (90) days following the occurrence of the Event of Loss to such
Engine, cause the Engine to be replaced and subjected to the Lien of this
Security Agreement. Any such replacement Engine shall be owned by the Mortgagor
free and clear of any liens and shall be of the same make and model and have the
same value and utility as the replaced Engine, assuming that such replaced
Engine was maintained in the condition required by this Security Agreement.

            (d) All Parts at any time removed from the Aircraft, Airframe or any
Engine shall remain subject to the Lien hereof, no matter where located, until
such time as such Parts shall be replaced by Parts which have been incorporated
in the Aircraft, Airframe or Engine which are owned by Mortgagor. All
replacement Parts shall be free and clear of all Liens (except for Permitted
Liens) and shall have a value and utility at least equal to the Parts replaced,
assuming such replaced Parts were in the condition and repair required to be
maintained by the terms hereof. Notwithstanding the foregoing, the Mortgagor or
any Lessee may use temporary parts or pooled parts on the Aircraft as temporary
replacements for Parts, provided that the Mortgagor or Lessee, at its expense,
as promptly thereafter as practicable, either (1) causes such pooled or
replacement part to become the property of the Mortgagor free and clear of all
Liens other than Permitted Liens, or (2) replaces such replacement part with a
further replacement part owned by the Mortgagor or Lessee which meets the
requirements of this Section 3.4, free and

                                       11
<PAGE>

clear of all Liens other than Permitted Liens. Immediately upon any replacement
Part becoming incorporated in the Aircraft, Airframe or such Engine as above
provided, without further act, (i) such replacement Part shall become subject to
the Lien hereof, and the replaced Part shall no longer be subject to the Lien
hereof, and (ii) such replacement Part shall be deemed part of the Aircraft,
Airframe or such Engine for all purposes hereof to the same extent as the Parts
originally incorporated in such Aircraft, Airframe or Engine. The Mortgagor (or
any Lessee), at its own expense, may from time to time make such alterations'
and modifications in and additions to the Airframe or any Engine as the
Mortgagor (or any Lessee) may deem desirable in the proper conduct of its
business, including removal of Parts which the Mortgagor (or any Lessee) deems
to be obsolete or no longer suitable or appropriate for use on the Airframe or
Engine (such removed Parts are hereinafter referred to as "Obsolete Parts");
provided that no such alteration, modification, removal or addition impairs the
condition or airworthiness of the Airframe or Engine, or diminishes the value
and utility of the Airframe or Engine below the value or utility thereof
immediately prior to such alteration, modification, removal or addition,
assuming the Airframe or Engine was then in the condition required to be
maintained by the terms of this Security Agreement absent such alteration,
modification, removal or addition, except that the value (but not the utility)
of the Airframe or any Engine may be reduced by the value of Obsolete Parts
which shall have been removed so long as the aggregate original value of all
Obsolete Parts which shall have been removed and not replaced shall not exceed
$400,000; provided further that no such removal shall be permitted if an Event
of Default shall have occurred and be continuing.

      (e) Notwithstanding any other provision of this Security Agreement, the
Mortgagor may install or permit to be installed in any Aircraft audio-visual,
entertainment, telephonic or other equipment owned by third parties (or owned
jointly by the Mortgagor and others) and leased or otherwise furnished to the
Mortgagor in the ordinary course of business, and the Lien of this Security
Agreement shall not attach thereto and the rights of the owners therein shall
not constitute a default hereunder or under the Credit Agreement.

      (f) In the case of an Event of Loss of an Airframe, the rights and
obligations of the parties hereto shall be governed by Section 6.15 of the
Credit Agreement. Following Mortgagee's release of a Removed Aircraft pursuant
to Section 6.15(d) of the Credit Agreement, and provided that no Default or
Event of Default has occurred and is continuing, Mortgagee shall promptly
transfer to Mortgagor all proceeds which the Mortgagee had received from the
Mortgagor's insurers pursuant to Section 3.5 herein and any investment earnings
thereon.

      (g) The Mortgagor shall not, when in possession of any portion of the
Flight Equipment, use or permit such portion of the Flight Equipment to be
operated except by pilots currently certified by the FAA to use and operate the
Flight Equipment.

      (h) Any part or item of property may be removed from the Flight Equipment
in order that the same may be inspected, repaired, reconditioned or otherwise
serviced without affecting or impairing the lien hereof with respect to such
part or item of property, provided that, whenever any such part or item is in
the possession of the Mortgagor, any such part or item shall be at all such
times covered by insurance against such risks and in such amounts as is
reasonably satisfactory to Mortgagor and provided that, other than in the case
of Obsolete parts, any such

                                       12
<PAGE>

part or item shall be replaced promptly after its removal by that same or an
equivalent part in as good working order as the part or item removed, assuming
such part or item was maintained and used as required by the provisions hereof
and shall be subject to the lien and security interest created pursuant to this
Security Agreement.

      3.5 Insurance.

            (a) The Mortgagor shall carry and maintain in effect, at its own
expense, with financially sound and reputable insurers, the following insurance
which will name as an additional insured party the Mortgagee:

                  (i) Comprehensive Airline Liability Insurance. Comprehensive
airline liability insurance (including, without limitation, contractual
liability, passenger legal liability and liability for property damage), in
amounts per occurrence of not less than Three Hundred Fifty Million Dollars
($350,000,000.00), or such greater amounts as the Mortgagor may carry. Each and
any policy of insurance carried in accordance with this subclause (i), and each
and any policy obtained in substitution or replacement for any of such policies,
(1) shall designate the Mortgagee (or any other holder from time to time of a
Note) as an additional insured (but without any obligation imposed upon the
additional insured, including, without limitation, the liability to pay any
premiums for any such policies, but the Mortgagee (or any other holder from time
to time of a Note) shall have the right to pay such premiums if it shall so
elect), (2) shall expressly provide that, in respect of the interest of the
Mortgagee (or any holder from time to time of a Note) in such policies, the
insurance shall not be invalidated by any action or inaction of any Person
(other than the Mortgagee (or any other holder from time to time of a Note) for
their respective interests), and shall insure, regardless of any breach or
violation by Mortgagor or any other Person (other than the Mortgagee (or any
other holder from time to time of a Note)) of any warranty, declaration or
condition contained in such policies, (3) shall provide that if such insurance
is canceled for any reason whatsoever, or is adversely changed in any way with
respect to the interest of the Mortgagee (or any holder from time to time of a
Note) or if such insurance is allowed to lapse for nonpayment of premium, such
cancellation, change or lapse shall not be effective as to the Mortgagee (or any
holder from time to time of a Note) for thirty (30) days (or such lesser time
which may be standard in the insurance industry and ten (10) days in the event
of nonpayment of premium), in each instance after receipt by the Mortgagee (or
any holder from time to time of a Note) of written notice by such insurer or
insurers sent to the Mortgagee (or any holder from time to time of a Note) of
such prospective cancellation, change or lapse, (4) shall include coverage for
any country in which the Flight Equipment is located, and (5) shall provide
that, as against the Mortgagee (or any holder from time to time of a Note), the
insurer shall waive any rights of set-off, counterclaim or any other deduction,
whether by attachment or otherwise, and waives any rights it may have to be
subrogated to any right of any insured against the Mortgagee (or any holder from
time to time of a Note) with respect to the Flight Equipment. Each liability
policy shall be primary without right of contribution from any other insurance
which may be carried by the Mortgagee (or any holder from time to time of a
Note) and shall expressly provide that all of the provisions thereof (except the
limits of liability) shall operate in the same manner as if there were a
separate policy covering each insured. No liability policy shall permit any
deductible or self-insurance provision in excess of Five Million

                                       13
<PAGE>

Dollars ($5,000,000). Such policy may be subject to the standard terms and
conditions contained in comprehensive airline liability policies.

                  (ii) Aircraft Hull War Risks and Allied Perils Insurance. Hull
war risk and allied perils insurance on the Flight Equipment (which shall
include, but not be limited to, coverage for hijacking, declared or undeclared
war, insurrections, strikes, riots, civil commotions or labor disturbances,
malicious acts or acts of sabotage, unlawful seizure or wrongful exercise of
control of the Flight Equipment in flight by a person on board such Flight
Equipment acting without the consent of the Mortgagor) in an amount not less
than the Current Market Value of the Aircraft in question, or such greater
amounts as the Mortgagor may carry.

                  (iii) All Risks Hull Insurance. "All risks" ground and flight
aircraft hull insurance covering the Flight Equipment, and fire, transit,
extended coverage, spares and all risks insurance with respect to the Engines
and Parts while not installed on the Aircraft. At all times while any part of
the Flight Equipment is subject to the Lien of Security Agreement, such
insurance shall be for an amount not less than the Current Market Value of the
Aircraft in question.

      Notwithstanding anything above, each and any policy of insurance obtained
and maintained pursuant to subclause (ii) and this subclause (iii), and each and
any policy obtained in substitution or replacement for any such policies, (1)
shall designate the Mortgagee as additional insured and as sole loss payee up to
the Current Market Value of the Aircraft in question (but without imposing upon
the Mortgagee any obligation imposed upon the insured, including, without
limitation, the liability to pay any premiums for any such policies, but the
Mortgagee shall have the right to pay such premiums if it shall so elect), (2)
shall expressly provide that, in respect of the interests of the Mortgagee in
such policies, the insurance shall not be invalidated by any action or inaction
of the Mortgagor or any other Person (other than the Mortgagee for its
interest), shall insure the Mortgagee, regardless of any breach or violation of
any warranty, declaration of condition contained in such policies by the
Mortgagor or any other Person (other than the Mortgagee for its interest), (3)
shall provide that if such insurance is canceled for any reason whatsoever, or
is adversely changed in any way with respect to the interest of the Mortgagee,
or if such insurance is allowed to lapse for nonpayment of premium, such
cancellation change or lapse shall not be effective as to the Mortgagee, for
thirty (30) days (or such lesser time which may be standard in the insurance
industry and ten (10) days in the event of nonpayment of premium) after receipt
by the Mortgagee of written notice (or in the case of War Risk insurance, seven
(7) days or such lesser time which may be standard in the war risk insurance
market after delivery of written notice) by such insurer or insurers to the
Mortgagee, as the case may be, of such prospective cancellation, change or
lapse, (4) shall include coverage for the territorial limits or any country in
which the Flight Equipment may at any time be located, but may include
geographic exclusions, (5) shall provide that, as against the Mortgagee, the
insurer shall waive any rights of set-off, counterclaim or any other deduction,
whether by attachment or otherwise, and waive any rights it may have to be
subrogated to any right of any insured against the Mortgagee, with respect to
the Flight Equipment, (6) shall provide that in the event of any damage or loss
which is an Event of Loss hereunder and which results in a payment, such payment
of up to the Current Market Value of the Flight Equipment suffering the Event of
Loss shall be payable solely and directly to the Mortgagee for the account of
all interests, (7)

                                       14
<PAGE>

shall provide that in the event of any damage or loss which is not an Event of
Loss hereunder and which results in a payment for any one occurrence in excess
of Five Million Dollars ($5,000,000), such payment shall be payable solely and
directly to the Mortgagee for the account of all interests, and (8) shall
provide that payments for any one occurrence not in excess of Five Million
Dollars ($5,000,000) shall be payable directly to the Mortgagor provided there
exists no Event of Default. Except during a period when an Event of Default has
occurred and is continuing, all losses will be adjusted with the insurers by the
Mortgagor (giving due regard to the interests of the Mortgagee and the Lenders).

      The Mortgagor shall have the right to carry insurance in excess of the
amounts required hereunder and the proceeds of such excess insurance shall be
payable to the Mortgagor. Similarly, the Mortgagee shall have the right to carry
additional and separate insurance for its own benefit at its own expense,
without, however, thereby limiting the Mortgagor's obligations under this
Section 3.5.

      The Mortgagor shall at all times maintain a deductible amount in its "all
risks" hull insurance policies which is no more than Five Million Dollars
($5,000,000).

            (b) The Mortgagor shall promptly notify the Mortgagee of, to the
knowledge of the Mortgagor, any material adverse change in the insurance
coverage required by this Section 3.5; and

            (c) Prior to the date of this Security Agreement, the Mortgagor
shall furnish, or cause to be furnished, to the Mortgagee from nationally
recognized independent aviation insurance brokers, certificates of insurance
certifying to such insurance coverage.

      All proceeds of insurance paid to the Mortgagee in accordance with this
Section 3.5 shall be held and paid over or applied by the Mortgagee as provided
in Section 2.1 or 2.2.

      3.6 Inspection by Mortgagee; Information.

The Mortgagor shall, at all such times, maintain and store, or cause to be
maintained and stored, records in accordance with the FAA regulations and
adequate to identify such Flight Equipment and to disclose its location, use and
maintenance, and upon reasonable notice and request of the Mortgagee, permit the
Mortgagee, its representatives and agents (or cause the Mortgagee, its
representatives and agents to be permitted if the following items are not in the
possession or control of Mortgagor) to inspect such Flight Equipment (including
all logs, maintenance cards, manuals and records with respect thereto) and, at
the expense of Mortgagee, to take copies and extracts therefrom, and shall
afford and procure a reasonable opportunity to make any such inspection, and the
Mortgagor shall furnish or cause to be furnished to the Mortgagee any and all
such other information and, at the expense of Mortgagee, copies of documents and
print-outs of data stored on any electronic or data processing medium, as are
reasonably available to the Mortgagor and the Mortgagee may reasonably request,
with respect to any Mortgaged Property, provided that any such inspection shall
be upon reasonable notice, shall be limited, in the absence of the continuation
of an Event of Default, to once a year at a mutually agreed time, and by a group
consisting of no more than two individuals.

                                       15
<PAGE>

      3.7 Registration. For so long as any part of the Flight Equipment is
subject to the Lien of this Security Agreement, the Mortgagor shall cause the
Aircraft to be registered at all times with the FAA in its name as owner
thereof.

      3.8 Insignia. The Mortgagor will plainly, distinctly and conspicuously
place or cause to be placed and leave in the cockpit of the Aircraft and upon
such other places as may reasonably be designated by the Mortgagee from time to
time, an insignia or other identification bearing words which indicate
Mortgagee's interest in the Aircraft, in letters of a size reasonable under the
circumstances and acceptable to the Mortgagee.

      3.9 Operation and Location. Mortgagor agrees that (a) it will not fly the
Aircraft or suffer the Aircraft to be flown in violation of any provision of any
insurance policy in effect with respect to the Aircraft or in violation of any
law, rule, regulation or order of the United States or any agency,
instrumentality or state or political subdivision thereof (including agencies
and instrumentalities of such state or political subdivision) or of any other
nation having jurisdiction over the use and operation of the Aircraft, except
(1) unanticipated minor violations not involving any material risk of the sale,
forfeiture or loss of an Aircraft, an Airframe, any Engine, or the Mortgagee's
interest therein, if such violation ceases promptly after discovery thereof by
the Mortgagor, or only requires the Mortgagor's payment of a fine levied only
against the Mortgagor, and (2) the Mortgagor or any Lessee may contest in good
faith the validity or application of any such law, rule, regulation, treaty,
order, certificate, license or registration, so long as there is no material
risk of the sale, forfeiture or loss of an Aircraft, an Airframe or any Engine,
or the Mortgagee's interest therein, (b) it shall not knowingly use or allow the
Aircraft to be used for the carriage of drugs or other illegal goods or any
other goods for which the Mortgagor or operator of the Aircraft is not licensed
to transport; and (c) it will not operate the Aircraft, or permit any Lessee to
operate the Aircraft: (i) in or to any area excluded from coverage by any
insurance required to be maintained by the terms of Section 3.5 hereof; (ii) in
countries with which the United States does not maintain full diplomatic
relations other than the Republic of China (Taiwan); and (iii) in or to any
areas of actual or threatened armed hostilities, provided, that the failure of
Mortgagor to comply with the provisions of this sentence shall not give rise to
an Event of Default where such failure is an isolated extraordinary occurrence
attributable to a hijacking, medical emergency, equipment malfunction, weather
condition, or navigational error. The Mortgagor shall also have the right to
operate any Aircraft without having on board the original registration
certificate or airworthiness certificate in the event that either or both such
certificates disappear from the Aircraft, but only to the extent permitted by
Exemption No. 5318 of the Federal Aviation Act or other similar exemption.

      3.10 Possession and Leases. The Mortgagor will not, without the prior
written consent of the Mortgagee, lease or otherwise in any manner deliver,
transfer or relinquish possession of the Airframe or any Engine or install or
permit any Engine to be installed on any airframe other than the Airframe;
provided that so long as no Event of Default shall have occurred and be
continuing at the time of such Lease, delivery, transfer or relinquishment of
possession or installation and the Mortgagor and/or any Lessee shall continue to
comply with the provisions of Section 3.3 and Section 3.4, the Mortgagor may,
without the prior written consent of the Mortgagee:

                                       16
<PAGE>

            (a) subject the Engine(s) or engines to normal interchange
agreements or any Engine to normal pooling or similar arrangements, in each case
customary in the airline industry and entered into by the Mortgagor (or any
Lessee) in the ordinary course of its business with a U.S. Air Carrier or any
other air carrier approved in writing by the Mortgagee (which approval will not
be unreasonably withheld or delayed); provided that (i) no such agreement or
arrangement contemplates or requires the transfer of title to any Engine and
(ii) if the Mortgagor's title to any Engine shall be divested under any such
agreement or arrangement, such divestiture shall be deemed to be an Event of
Loss with respect to such Engine and the Mortgagor shall (or shall cause any
Lessee to) comply with Section 3.4 (c) hereof in respect thereof;

            (b) deliver possession of the Airframe or any Engine to the Airframe
manufacturer or the Engine manufacturer, or to any Person for testing, service,
repair, maintenance or overhaul work on the Airframe or any Engine or for
alterations or modifications in or additions to the Airframe or Engine(s) to the
extent required or otherwise not prohibited by the terms hereof or of the Credit
Agreement;

            (c) install an Engine on an airframe owned by the Mortgagor (or any
Lessee), leased to the Mortgagor (or any Lessee), or owned or purchased by the
Mortgagor (or any Lessee) subject to a conditional sale or other security
agreement, provided that (a) such airframe is free and clear of all Liens,
except (i) in the case of airframes leased to the Mortgagor (or any Lessee) or
owned or purchased by the Mortgagor (or any Lessee) subject to a conditional
sale or other security agreement, the rights of the parties to the Lease or
conditional sale agreement or other security agreement covering such airframe,
or their assignee, (ii) Permitted Liens, and (iii) the rights of other air
carriers under normal interchange agreements which are customary in the airline
industry and do not contemplate, permit or require the transfer of title to the
airframe or engines installed thereon, and (b) any such lease, conditional sale
or other security agreement provides that such Engine shall not become subject
to the lien of such lease, conditional sale or other security agreement,
notwithstanding the installation thereof on such airframe, and the inclusion in
such agreement of a provision similar to the last paragraph of this Section 3.4
(c) shall satisfy such requirement;

            (d) install an Engine on an airframe owned by the Mortgagor (or any
Lessee), leased to the Mortgagor (or any Lessee) or purchased by the Mortgagor
(or any Lessee) subject to a conditional sale or other security agreement under
circumstances where paragraph 3.10 (c) above is inapplicable, provided that such
installation shall be deemed an Event of Loss with respect to such Engine and
the Mortgagor shall (or shall cause any Lessee to) comply with Section 3.4 (c)
hereof in respect thereof, the Mortgagee not intending hereby to waive any right
or interest it may have to or in such Engine under applicable law until
compliance by the Mortgagor with such Section 3.4 (c);

            (e) transfer (or permit any Lessee to transfer) possession of the
Airframe or any Engine to the United States of America or any instrumentality or
agency thereof pursuant to CRAF so long as the Mortgagor (or such Lessee) shall
promptly notify the Mortgagee upon transferring possession of the Airframe or
any Engine to the United States of America or any

                                       17
<PAGE>

agency or instrumentality thereof pursuant to such program and provide the
Mortgagee with the name and address of the Contracting Office Representative for
the Military Aircraft Command of the United States Air Force to whom notice must
be given in the event the Mortgagee desires to give notice as provided in
Section 4.2 hereof;

            (f) provided that no Event of Default has occurred and is
continuing, enter into a lease with: (a) any certificated U.S. Air Carrier not
then subject to bankruptcy, reorganization or insolvency proceedings; (b) any
other non-U.S. air carrier if at the time of such lease the United States of
America maintains normal diplomatic relations with the country in which such air
carrier is based and the Mortgagee shall have received (A) evidence that: (1)
all necessary governmental approvals required for the leased equipment, the
Airframe or any Engine, as the case may be, to be imported and, if requested by
the Mortgagee (and such request is reasonable in light of the circumstances) and
if and to the extent obtainable with reasonable effort and if it is otherwise
customary to obtain the same in such jurisdiction, exported from the applicable
country of domicile upon repossession of such leased equipment by the Mortgagee
(and the Mortgagor as lessor) shall have been obtained prior to commencement of
any such lease; and (2) the insurance requirements of Section 3.5 are satisfied
and that War Risk Insurance shall be carried and maintained of such scope and
coverage, and subject to such exclusions and exceptions, as is standard for air
carriers flying similar equipment on routes comparable to those flown by the
Aircraft and (B) an opinion of counsel (which counsel and opinion are reasonably
satisfactory to the Mortgagee) that: (1) it is not necessary for the Mortgagee
to register or qualify to do business in such jurisdiction solely as a result of
the proposed lease, unless the only result of such registration or qualification
is a Tax or cost that the Mortgagor is indemnifying such party against; (2) that
the Mortgagee's Lien on the leased equipment will be recognized; (3) the laws of
such jurisdiction of domicile require fair compensation by the government of
such jurisdiction payable in a currency freely convertible into Dollars for the
loss of the title to the leased equipment in the event of the requisition by
such government of title (unless the Mortgagor shall provide insurance covering
the risk of requisition of title to the leased equipment by the government of
such jurisdiction so long as the leased equipment is subject to such lease); (4)
the required agreement of such non-U.S. air carrier that its rights under the
Lease are subject and subordinate to all of the terms of this Security Agreement
is enforceable against such non-U.S. air carrier under applicable law (subject
only to customary exceptions to enforceability); (5) there exist no possessory
rights in favor of such Lessee under the laws of such jurisdiction which would,
upon bankruptcy of the Mortgagor or other default by the Mortgagor or Lessee and
assuming that at such time such Lessee is not insolvent or bankrupt, prevent the
return of the Aircraft to the Mortgagor or the Mortgagee in accordance with and
when permitted by the terms of Section 4.2 hereof upon the exercise by the
Mortgagee of remedies under Section 4.2 hereof; and (6) the terms (including,
without limitation, the governing-law and jurisdictional-submission provisions
hereof) of this Security Agreement are legal, valid, binding and enforceable in
such jurisdiction against third parties to substantially the same extent as in
the United States; or (c) any Person approved in writing by the Mortgagee, which
approval shall not be unreasonably withheld. The currency of payments under such
Lease must be freely convertible into Dollars.

      The rights of any Lessee or other transferee who receives possession by
reason of a transfer permitted by this Section 3.10 (other than the transfer of
an Engine deemed an Event of

                                       18
<PAGE>

Loss) shall be subject and subordinate to, and any Lease permitted by this
Section 3.10, shall expressly provide that it is subject and subordinate to, all
the terms of this Security Agreement; provided that in the case of the use of
the Aircraft in CRAF the subject and subordinate requirements herein shall be
subject to the notice specified in Section 4.2 and other requirements of the
CRAF program. In the case of any Lease, the Mortgagor shall remain primarily
liable hereunder for the performance of all of the terms of this Security
Agreement, and the terms of any such Lease shall not permit any Lessee to take
any action not permitted to be taken by the Mortgagor hereunder with respect to
the Aircraft and may permit the Mortgagor to cure any default by Lessee and to
terminate the Lease upon such default; provided, however, that the Mortgagor may
procure such performance from any Lessee pursuant to the relevant Lease, and the
Mortgagee hereby agrees to accept such performance by such Lessee in
satisfaction of the Mortgagor's obligations hereunder; and provided further that
all rights accruing hereunder to the Mortgagor shall likewise accrue to such
Lessee to the extent Mortgagor so permits. Subject to the Mortgagor's
obligations in paragraph (g) above, the Mortgagor shall promptly notify the
Mortgagee after entering into any Lease.

      Any Wet Lease or similar arrangement under which the Mortgagor maintains
operational control of the Aircraft shall not constitute a delivery, transfer or
relinquishment of possession for purposes of this Section 3.10. Any
consolidation or merger of the Mortgagor or conveyance, transfer or lease of all
or substantially all of the Mortgagor's assets permitted by the Credit Agreement
shall not be prohibited by this Section 3.10. As used herein, "Wet Lease" shall
mean any arrangement whereby the Mortgagor or a Lessee agrees to furnish the
Airframe and Engines or engines installed thereon to a third party pursuant to
which the Airframe and Engines or engines (i) shall be operated solely by
regular employees of the Mortgagor, or Lessee possessing all current
certificates and licenses required under the Federal Aviation Act, and (ii)
shall be maintained by the Mortgagor or Lessee in accordance with the
Maintenance Program or an FAA approved maintenance program.

      The Mortgagee agrees, for the benefit of the Mortgagor (and any Lessee)
and for the benefit of any mortgagee or other holder of a security interest in
any engine owned by the Mortgagor (or any Lessee), any lessor of any engine
leased to the Mortgagor (or any Lessee) and any conditional vendor of any engine
purchased by the Mortgagor (or any Lessee) subject to a conditional sale
agreement or any other security agreement, that no interest shall be created
hereunder in any engine so owned, leased or purchased and that neither the
Mortgagee nor its successors or assigns will acquire or claim, as against the
Mortgagor (or any Lessee) or any such mortgagee, lessor or conditional vendor or
other holder of a security interest or interest in such engine as the result of
such engine being installed on the Airframe; provided, however, that such
agreement of the Mortgagee shall not be for the benefit of any lessor or secured
party of any airframe leased to the Mortgagor (or any Lessee) or purchased by
the Mortgagor (or any Lessee) subject to a conditional sale or other security
agreement or for the benefit of any mortgagee of or any other holder of a
security interest in an airframe owned by the Mortgagor (or any Lessee), unless
such lessor, conditional vendor, other secured party or mortgagee has agreed
(which agreement may be contained in such lease, conditional sale or other
security agreement or mortgage and may consist of a paragraph similar to this
paragraph) that neither it nor its

                                       19
<PAGE>

successors or assigns will acquire, as against the Mortgagee, any right, title
or interest in an Engine as a result of such Engine being installed on such
airframe.

      3.11. Substitution of Engines. So long as no Event of Default shall have
occurred and be continuing, Mortgagor shall have the right at its option at any
time in accordance with Section 6.15(c) of the Credit Agreement, to terminate
the Lien of this Security Agreement with respect to any Engine. Subject to
Section 6.15(c) of the Credit Agreement, at the time of any such termination,
Mortgagor shall replace such engine hereunder by complying with the terms of
Section 3.4 (c) hereof to the same extent as if an Event of Loss had occurred
with respect to such Engine (other than the time periods allowed for such
replacement), and the Mortgagee shall release the replaced Engine from the Lien
of this Security Agreement as by entering into a Security Agreement Supplement
in the form of Schedule II.

SECTION 4. EVENTS OF DEFAULT and REMEDIES

      4.1. Events of Default.

      (a) Each Event of Default set forth in Section 8.01 of the Credit
Agreement is incorporated herein as if fully set forth as a separate Event of
Default in this Section 4.1.

      (b) The Mortgagor shall fail to procure and maintain (or cause to be
procured and maintained), with respect to the Aircraft, insurance required to be
maintained in accordance with the provisions of Section 3.5 hereof or such
insurance shall lapse or be canceled, provided that no such lapse or
cancellation shall constitute an Event of Default until the earlier of thirty
(30) days (or if 30 days is unavailable pursuant to Section 3.5 hereof, such
shorter period as is available pursuant to such Section) after receipt by the
Mortgagor of written notice of such lapse or cancellation (or seven (7) days or
such shorter time as may be standard in the industry with respect to War Risk
Insurance provided that if the Aircraft is grounded or if War Risk Insurance or
indemnification is provided by the FAA, no such failure to carry War Risk
Insurance shall be an Event of Default) or the date that such lapse or
cancellation is effective as to Mortgagee; or

      (c) The Mortgagor shall have failed to perform or observe, or caused to be
performed and observed, any other covenant or agreement contained in this
Security Agreement, and such failure shall continue unremedied for a period of
thirty (30) days after the Mortgagor's receipt of written notice thereof from
the Mortgagee; provided, however, that if such failure is curable, and if the
Mortgagor shall have undertaken to cure any such failure and, notwithstanding
the reasonable diligence of the Mortgagor in attempting to cure such failure,
such failure is not cured within said thirty (30) day period but is curable with
future due diligence, there shall exist no Event of Default under this Section
4.01 for such further time not to exceed 180 days as may reasonably be required
to effect such cure, so long as the Mortgagor is proceeding with due diligence
to cure such failure.

      4.2. Remedies. Upon the occurrence of an Event of Default, the Mortgagee
may accelerate the entire balance then due and owing under the Credit Agreement
and this Security Agreement, whereupon all such sums shall become immediately
due and payable, and thereafter

                                       20
<PAGE>

the Mortgagee may, at its option, do one, several or all of the following as the
Mortgagee in its sole discretion shall then elect:

            (a) exercise all the rights and remedies granted to secured parties
by the provisions of the UCC or under the provisions of any applicable law;

            (b) personally, or by agents or attorneys, take possession of all or
any part of the Mortgaged Property, and demand, sue for, collect or receive any
money or property at any time payable or receivable on account of or in exchange
for, or make any compromise or settlement deemed desirable with respect to, any
of the Mortgaged Property or any sum payable in connection therewith;

            (c) personally, or by agents or attorneys, take possession of any
part or all of the Mortgaged Property without being responsible for loss or
damage caused thereby, and sell or dispose of all or any part of the same, free
from any and all claims of the Mortgagor or of any other party claiming by,
through or under the Mortgagor, at law or in equity, at one or more public or
private sales on such commercially reasonable terms as the Mortgagee may in good
faith fix, with or without any previous demand or notice to the Mortgagor or
advertisement of any such sale or other disposal except as is commercially
reasonable under the circumstances, and any notice or demand and right of equity
or redemption otherwise required by or available to the Mortgagor under
applicable law is hereby waived by the Mortgagor to the fullest extent permitted
by applicable law;

            (d) institute legal proceedings for the sale or otherwise for the
enforcement of any right, under the judgment of any court of competent
jurisdiction, of or concerning any of the Mortgaged Property;

            (e) institute legal proceedings to foreclose upon and against the
security interest granted in and by this Security Agreement or to recover
judgment for the amounts then due from Mortgagee under this Security Agreement
or under the Credit Agreement.

            (f) institute legal proceedings for the specific performance of any
covenant or agreement contained in this Security Agreement or in aid of the
execution of any power granted in this Security Agreement, and the Mortgagee
shall be entitled as of right to the appointment of a receiver of all or any
part of the Mortgaged Property; and

            (g) exercise all of the rights and remedies of the Mortgagee against
the Mortgagor under the Credit Agreement.

      provided that during any period the Aircraft is activated under CRAF in
accordance with the provisions of Section 3.10 hereof and in the possession of
the government of the United States of America or an instrumentality or agency
thereof, the Mortgagee shall not, on account of any Event of Default, be
entitled to do any of the foregoing or require Mortgagor to do anything as
permitted in Section 4 in such manner as to limit the Mortgagor's control under
this Security Agreement of any Airframe or any Engines installed thereon, unless
at least sixty (60) days' (or such lesser period as may then be applicable under
the Military Airlift Command program of the

                                       21
<PAGE>

government of the United States of America) prior written notice of default
hereunder shall have been given by the Mortgagee by registered or certified mail
to the Mortgagor with a copy addressed to the Contracting Office Representative
for the Military Airlift Command of the United States Air Force under the
contract with the Mortgagor relating to any Airframe.

            4.2.1. Multiple Sales. The power of sale under this Security
Agreement shall not be exhausted by one or more sales, and the Mortgagee may
from time to time adjourn any sale to be made pursuant to this Security
Agreement. The Mortgaged Property need not be present at the time and place of
sale.

            4.2.2. Delivery of Mortgaged Property. If the Mortgagee shall demand
possession of the Mortgaged Property or any part thereof pursuant to this
Security Agreement, the Mortgagor shall, at its own expense, forthwith cause
such Mortgaged Property or any part thereof designated by the Mortgagee to be
assembled and made available and delivered to the Mortgagee at any place
reasonably designated by the Mortgagee.

            4.2.3. Mandatory Notices. In addition to any other notices required
by applicable law, the Mortgagee shall give to the Mortgagor at least 15 days
prior written notice of each public sale or any date after which a private sale
or other intended disposition hereunder shall occur, and the Mortgagor hereby
covenants and agrees that a notice which shall be given, in accordance with the
provisions of Section 6.1 below, at least 15 calendar days before the date of
any such act shall be deemed to be reasonable notice for such act and
specifically, reasonable notification of the time and place of any public sale
hereunder and of reasonable notification of the time after which any private
sale or other intended disposition of the Mortgaged Property (or any part
thereof) to be made hereunder is to be made.

            4.2.4. Mortgagee Repairing Mortgaged Property. Upon every such
taking of possession until the Mortgaged Property is foreclosed upon, the
Mortgagee may, but shall have no obligation to, from time to time at the expense
of the Mortgagor, make all such repairs, replacements, alterations,
modifications, additions and improvements to and of the Mortgaged Property as
the Mortgagee may reasonably determine to be commercially reasonable. In each
such case, the Mortgagee shall have the right to manage and control the
Mortgaged Property and to exercise all rights and powers of the Mortgagor in
respect thereof as the Mortgagee shall deem best, including the right to enter
into any and all such agreements with respect to the leasing or operation of the
Mortgaged Property or any part thereof as the Mortgagee may see fit. The
Mortgagee shall be entitled to collect and receive all rents, issues, profits,
revenues and other income of the same and every part of the Mortgaged Property.
Such rents, issues, profits, revenues and other income shall be applied to pay
the expenses of holding and operating the Mortgaged Property, and of all
maintenance, repairs, replacements, alterations, additions and improvements, and
to make all payments which the Mortgagee may be required or may elect to make,
if any, for taxes, assessments, insurance and other charges upon the Mortgaged
Property or any part thereof, and all other payments which the Mortgagee may be
required or authorized to make under any provision of this Security Agreement.
The remainder of such rents, issues, profits, revenues and other income shall be
applied only in accordance with Section 4.2.6.

                                       22
<PAGE>

            4.2.5. Delivery to Purchaser. Upon the completion of any sale under
this Section 4, the Mortgagor shall deliver or; cause to be delivered all of the
property, sold to the purchaser or purchasers at such sale on the date of sale,
or within a reasonable time thereafter if it shall be impractical to make
immediate delivery, but in any event full title and right of possession to such
property shall pass to such purchaser or purchasers forthwith upon the
completion of such sale. Nevertheless, if so requested by the Mortgagee or by
any purchaser, the Mortgagor shall confirm any such sale or transfer by
executing and delivering to such purchaser all proper instruments of conveyance
and transfer and releases as may be designated in any such request. Every such
sale shall operate to divest all right, title, interest, claim and demand
whatsoever of the Mortgagor in and to the property so sold, and shall be a
perpetual bar, both at law and in equity, against the Mortgagor and all persons
claiming the property sold, or any part thereof, through the Mortgagor and its
successors or assigns.

            4.2.6. Application of Proceeds. The proceeds of any sale of the
Mortgaged Property, or any part thereof, under this Section 4, together with any
other sums then held by the Mortgagee as part of the Mortgaged Property, shall
be applied as follows:

            (a) first, to the payment of the cost and expenses of such sale,
including brokers' fees or sales commissions, a reasonable compensation to the
Mortgagee's agents, attorneys and counsel, all charges, expenses, liabilities
and advances incurred or made by the Mortgagee, and the payment of all taxes,
assessments or liens, if any, prior to the lien of this Security Agreement,
except any taxes, assessments or liens subject to which such sale shall have
been made;

            (b) second, to the payment of all amounts owing in respect of the
      Obligations; and

            (c) third, the surplus, if any, shall be paid to the Mortgagor or to
      anyone entitled to payment thereof by operation of law or pursuant to an
      order of a court of competent jurisdiction.

            4.2.7. Mortgagee May Purchase. At any sale under this Section 4, to
the extent permitted by applicable law, the Mortgagee may bid for and purchase
the property offered for sale and, upon compliance with the terms of sale, may
bid, retain and dispose of such property without further accountability
therefor. The Mortgagee may apply against the purchase price for the Mortgaged
Property or any part thereof the amount then due under the Credit Agreement
secured hereby. The Mortgagee need not be present at such sale.

            4.2.8. Right to Possession. In the event Mortgagor becomes subject
to the jurisdiction of any United States Bankruptcy Court in a proceeding for
the reorganization of Mortgagor, the Mortgagor hereby waives, to the fullest
extent permitted by applicable law, any right to contest any motion, petition or
application filed by the Mortgagee with such bankruptcy court having
jurisdiction over the Mortgagor, whereby Mortgagee seeks to enforce any of its
remedies under this Security Agreement or the Credit Agreement (including, in
connection with the enforcement of such remedies, any motion or application made
by Mortgagee for relief from any stay to which Mortgagee is subject).

                                       23
<PAGE>

            4.2.9. Remedies Cumulative. Each right, power and remedy
specifically given to the Mortgagee in this Security Agreement or otherwise
existing shall be cumulative and shall be in addition to every other right,
power and remedy specifically given in this Security Agreement, in any other
Loan Documents, or now or hereafter existing at law, in equity or otherwise.
Each such right, power and remedy, whether specifically given in the Credit
Agreement or otherwise existing, may be exercised from time to time and as often
and in such order as may be deemed expedient by the Mortgagee. The exercise of
any such right, power or remedy shall not be construed to be a waiver of the
right to exercise at the same time or thereafter any other right, power or
remedy. No delay or omission by the Mortgagee in the exercise of any right or
power, or in the pursuance of any remedy, shall impair any such right, power or
remedy or be construed to be a waiver of any default on the part of the
Mortgagor or to be an a quiescence therein. No waiver by the Mortgagee of any
breach, Default or Event of Default by the Mortgagor shall be deemed a waiver of
any other previous breach, Default or Event of Default or any thereafter
occurring. The invalidity of any remedy in any jurisdiction shall not invalidate
such remedy in any other jurisdiction. The invalidity or unenforceability of any
of the remedies herein provided in any jurisdiction shall not in any way affect
the right to the enforcement in such jurisdiction or elsewhere of any of the
other remedies herein provided.

            4.2.10. Except as otherwise provided in this Security Agreement, the
Mortgagor hereby waives, to the extent permitted by Applicable Law, notice and
judicial hearing in connection with the Mortgagee's taking possession or the
Mortgagee's disposition of the aircraft, including, without limitation any and
all prior notice and hearing for any prejudgment remedy or remedies and any such
right which the Mortgagor would otherwise have under the constitution or any
statute of the United States or of any state, and the Mortgagor hereby further
waives, to the extent permitted by Applicable Law:

            (a) all damages occasioned by such taking of possession except any
damages which are the direct result of the Mortgagee's gross negligence or
willful misconduct;

            (b) all other requirements as to the time, place and terms of sale
or other requirements with respect to the enforcement of the Mortgagee' s rights
hereunder; and

            (c) all rights of redemption, appraisement, valuation, stay,
extension or moratorium now or hereafter in force under any Applicable Law in
order to prevent or delay the enforcement of this Security Agreement or the
absolute sale of the Aircraft or any part thereof, and the Mortgagor for itself
and all who may claim under it, insofar as it or they now or hereafter lawfully
may, hereby waives the benefit of all such laws.

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 Mortgagor therein
and thereto, and shall be a perpetual bar both at law and in equity against the
Mortgagor 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 Mortgagor.

                                       24
<PAGE>

            4.2.11. Right to Perform and Incur Expenses.

            (a) At any time and from time to time after an Event of Default, if
the Mortgagor fails to perform or fulfill any of its undertakings or obligations
contained herein, Mortgagee shall have the right, but shall not be obligated,
(i) to effect such performance or compliance, and (ii) to incur such reasonable
expenses relative to such performance or compliance, to the enforcement of
Mortgagee's rights or to the preservation, protection, reconditioning, storage
or sale of the Mortgaged Property, including such sums as are specified in
Section 4.2.4. and 4.2.6 (b). The amount of any such expenses and other
reasonable costs shall become payable by the Mortgagor to the Mortgagee as of
the date on which Mortgagee shall pay the same, together with interest thereon
from said date of payment up to and including the date of actual payment by the
Mortgagor at an interest rate equal, to the default rate of interest set forth
in the Credit Agreement (but in no event higher than the highest rate permitted
by applicable law).

            (b) All such costs and expenses incurred shall become part of the
Mortgagor's Obligations and shall become part of the indebtedness secured by
this Security Agreement. The Mortgagee shall have the right (but shall not be
obligated) to use and apply any Cash Collateral at any time held by it for the
repayment of all such advances, costs or expenses. However, no such use of any
Cash Collateral, nor the making by Mortgagee of any advance in payment of any
such expense, shall relieve the Mortgagor from any Event of Default.

            4.2.12. Power of Attorney.

            THE MORTGAGOR HEREBY CONSTITUTES AND APPOINTS THE MORTGAGEE ITS TRUE
AND LAWFUL ATTORNEY, IRREVOCABLY, WITH FULL POWER AFTER THE OCCURRENCE OF AND
DURING THE CONTINUANCE OF AN EVENT OF DEFAULT (IN THE NAME OF THE MORTGAGOR OR
OTHERWISE) TO ACT, REQUIRE, DEMAND, RECEIVE, COMPOUND AND GIVE ACQUITTANCE FOR
ANY AND ALL MONIES AND CLAIMS FOR MONIES DUE OR TO BECOME DUE TO THE MORTGAGOR
UNDER OR ARISING OUT OF THE COLLATERAL, TO ENDORSE ANY CHECKS OR OTHER
INSTRUMENTS OR ORDERS IN CONNECTION THEREWITH AND TO FILE ANY CLAIMS OR TAKE ANY
ACTION OR INSTITUTE ANY PROCEEDINGS WITH THE MORTGAGEE MAY DEEM TO BE NECESSARY
OR ADVISABLE IN THE PREMISES, WHICH APPOINTMENT AS ATTORNEY IS COUPLED WITH AN
INTEREST.

SECTION 5. DEFEASANCE

            If the Mortgagor shall pay and discharge all of its respective
Obligations, then upon Mortgagor Request this Security Agreement and the lien,
rights and interests granted by this Security Agreement shall cease, terminate
and become null and void and, at the expense of the Mortgagor, the Mortgagee
shall execute and deliver to the Mortgagor satisfaction and discharge of this
Security Agreement by such instruments of satisfaction as may be necessary, and
pay and deliver upon Mortgagor Order all monies and other personal property then
held by the Mortgagee under this Security Agreement.

SECTION 7 THE MORTGAGEE

      The Mortgagee may execute any of its duties or powers hereunder by or
through agents or employees, and shall be entitled to retain counsel and the
advice of such counsel concerning all matters pertaining to the performance of
its functions hereunder. The Mortgagor agrees to reimburse the Mortgagee for all
reasonable out-of-pocket expenses incurred by the Mortgagee and the counsel,
attorneys, agents and the employees of the Mortgagee in acting hereunder,
including any reasonable counsel fees and compensation paid for services
rendered to the Mortgagee in connection with the performance of its functions
hereunder if and to the extent reasonably engaged by Mortgagee. The Mortgagor
agrees to indemnify and save harmless the Mortgagee against and from any
liability or damages which the Mortgagee may incur or sustain in the exercise
and performance of any of the Mortgagee's powers and duties hereunder, not
including, however, the Mortgagee's gross negligence or willful misconduct. For
such

                                       27
<PAGE>

reimbursement and indemnity, the Mortgagee shall be secured under this Security
Agreement and, to effect such reimbursement and indemnity, the Mortgagee shall
have the right to use and apply any cash constituting Mortgaged Property at any
time held by it. The Mortgagee shall give notice to the Mortgagor of any actions
or claims to be brought against the Mortgagor under this Section 7; provided,

the UCC concerning security interests, and the parties to this Agreement agree
that the provisions of the UCC giving rights to a secured party shall
nonetheless be a part of this Agreement. Without limited the generality of the
foregoing, Debtor agrees that Agent may, subject to the requirements of Laws
including, without limitation, those affecting the offering and sale of
securities, sell, resell, assign, transfer or otherwise dispose of any or all of
the Other Cash Collateral set forth on Schedule 2(b). Debtor expressly
authorizes Agent at any time and from time to time, without prior notice to
Debtor, any such notice being waived by Debtor to the fullest extent permitted
by law, to set-off and apply any and all deposits (including, without
limitation, the Account) at any time held by Agent against the Obligations,
irrespective of whether or not Agent shall have made demand therefor.

      9. RELEASE OF NEW COLLATERAL. Upon the payment in full in cash of all the
Obligations and termination of this Agreement, the Credit Agreement, and each
other Loan Document, Agent shall upon request of Debtor promptly release the
Account from the lien, pledge and security interest created under this
Agreement. Release of such lien, pledge and security interest shall also be
subject to the Collateral release and substitution provisions in Section 6.15 of
the Credit Agreement.

      EXECUTED AND DELIVERED by the duly authorized officers of the parties as
of the date first above written.

Exhibit 10.53

John E. Trewin

414 Sonora Drive

San Mateo, CA 94402

Dear John:

We are pleased to offer you the position of Senior Vice President and Chief Financial Officer,
reporting to me.

Your salary will be $250,000 annually and will be paid bi-weekly. In addition, you will be
eligible to participate in Covad’s Bonus Program. Based on the 2005 bonus plan, you are eligible
for a total annual bonus target of 60% of base pay (payable at 12% of actual salary paid in each
quarter, and a year end individual bonus target of 12% of actual salary paid during the year).

The quarterly bonus target is based on recurring revenue, company performance (attainment of
profitability) and customer satisfaction measures. The year-end bonus target is solely based on
individual performance.

We will also recommend to the Board of Directors that you be granted an option for 125,000 shares
of Covad’s Common stock. The exercise price of the option will generally be the closing price for
Covad common stock on the last trading day of the month in which you start, provided it is approved
by the Board of Directors.

The options will vest on Covad’s standard vesting schedule (twelve forty-eight’s of the shares vest
on your one-year anniversary with the Company and one forty-eight per month for the next thirty six
months). In addition, you will be eligible for the standard Covad benefits program.

For the purposes of Federal Immigration (Immigration Reform and Control Act of 1987), you will be
required to provide documentary evidence of your identity and eligibility for employment in the
United States. We ask that you provide this information on your first work day. In addition, we
require that you complete on your first date of employment Covad’s Confidentiality and Inventions
Agreement.

This agreement, among other things, obligates you not to reveal any Covad confidential information;
not to bring with you to Covad any non-public, proprietary information of your previous employer or
any other party; not to discuss such information with Covad; and to continue to honor any existing
confidentiality obligations you have to your previous employer or any other company. It also
assigns Covad any rights you may have in work-related inventions you may develop while at Covad.

Covad hires and retains talented, qualified and committed professionals. To uphold the highest
standards so that we continue to provide top quality service, and to ensure a safe and secure work
environment, Covad initiates background checks on all newly hired Covad employees.

This offer of employment is contingent upon your successful completion of reference checks and a
background check, which may include verification of your past employment and education, as well as
a review of DMV and criminal record.

 

 

John, I am confident you can have a major impact on the success of Covad and will be a key member
of our team. Please review your offer and call me if you have any questions.

To accept, sign the enclosed copy and fax it to Jessica Rossman at 408 952-7404 at your earliest
convenience.

I look forward to your favorable reply and welcoming you to Covad.

Sincerely,

Charles Hoffman

Chief Executive Officer

I accept this offer of employment with the understanding that it is not an employment contract and
the provisions stated in this offer of employment constitute the entire and exclusive agreement
with respect to this subject matter, and no further commitments have been made to me. Neither this
nor any writing by Covad is intended to modify the presumptions of at-will employment status.
