                                CREDIT AGREEMENT

         THIS CREDIT AGREEMENT dated as of May 19, 2000 (as amended,
supplemented or otherwise modified, this "Agreement") by and among DELTA AIR
LINES, INC., a corporation organized under the laws of the State of Delaware
(the "Company"), each of the financial institutions initially a signatory hereto
together with those assignees pursuant to Section 10.6 hereof (collectively, the
"Banks" and each individually, a "Bank"), BAYERISCHE HYPO- UND VEREINSBANK AG,
New York Branch, as Letter of Credit Bank and BAYERISCHE HYPO- UND VEREINSBANK
AG, New York Branch, in its capacity as agent for the Banks (the "Agent").

                                    ARTICLE I

                                   DEFINITIONS

         Section 1.1. Definitions. In addition to terms defined elsewhere
herein, the following terms shall have the following meanings for the purposes
of this Agreement:

                  "Agent" shall mean Bayerische Hypo- und Vereinsbank AG, New
         York Branch in its capacity as agent for the Banks; provided, however,
         that if Bayerische Hypo- und Vereinsbank AG, New York Branch shall have
         resigned or been removed as Agent, then "Agent" shall mean the bank
         selected as Agent pursuant to the provisions of Section 9.8 hereof.

                  "Airline Subsidiary" shall mean Comair, Inc., Atlantic
         Southeast Airlines, Inc. and any other Subsidiary of the Company
         holding an airline operating certificate issued by the Federal Aviation
         Administration of the United States under FAR Part 121.

                  "Applicable Letter of Credit Fee" shall mean, as of any date
         of determination, the percentage rate set forth below corresponding to
         the long term senior unsecured debt rating of the Company, as rated by
         S&P (the "S&P Rating") and Moody's (the "Moody's Rating"; each of the
         S&P Rating and the Moody's Rating referred to herein as a "Rating"):

         rating followed by     or Baal or                                                          Ba2 or lower
         Moody's rating)        higher

         ---------------------- ----------------- --------------- ----------------- --------------- ----------------
</TABLE>

         The Agent shall determine the Applicable Letter of Credit Fee from time
to time in accordance with the above table and notify the Company and the Banks
of such determination from time to time. In the event the S&P Rating and the
Moody's Rating correspond to different

<PAGE>

levels on the above table resulting in different Applicable Letter of Credit Fee
determinations, the following provisions shall apply. In the event the S&P
Rating and the Moody's Rating differ by one level, the Applicable Letter of
Credit Fee shall be that corresponding to the higher Rating. For example, a
"BBB+" S&P Rating and a "Baa2" Moody's Rating would result in an Applicable
Letter of Credit Fee equal to 0.625%. In the event the S&P Rating and the
Moody's Rating differ by two levels, the Applicable Letter of Credit Fee shall
be that corresponding to that level which is in between the two applicable
levels. For example, a "BBB" S&P Rating and a "Ba1" Moody's Rating would result
in an Applicable Letter of Credit Fee equal to 0.875%. In the event the S&P
Rating and the Moody's Rating differ by three levels, the Applicable Letter of
Credit Fee shall be that corresponding to the level immediately below the higher
of such Ratings. For example, a "BBB+" S&P Rating and a "Ba1" Moody's Rating
would result in an Applicable Letter of Credit Fee equal to 0.750%. In the event
the S&P Rating and Moody's Rating differ by four levels (i.e. a ratings split
between level 1 and level 5), the Applicable Letter of Credit Fee shall be that
corresponding to level 4 (i.e. a "BBB+" S&P Rating and a "Ba2" Moody's Rating
would result in an Applicable Letter of Credit Fee equal to 1.25%).

         In the event only one rating agency exists or continues rating the
Company's long term senior unsecured debt, such agency's rating shall be used
for purposes of the above table. In the event: (i) neither agency exists or
continues rating the Company's long term senior unsecured debt or (ii) the
Company no longer has any outstanding long term senior unsecured debt to be
rated, the Applicable Letter of Credit Fee for the first 90 days after such
occurrence shall be the Applicable Letter of Credit Fee in effect as determined
above immediately prior to such occurrence. During such 90-day period, the Agent
and the Company shall negotiate in good faith to agree upon a new pricing grid
or other appropriate pricing terms. Any such new grid or pricing terms shall be
approved by the Banks. In the event the Agent, the Company and the Banks cannot
agree upon such new pricing grid or pricing terms by the end of such 90-day
period, the Applicable Letter of Credit Fee shall be that corresponding to level
5 of the above table for the remainder of the term of the Agreement. Any
necessary adjustment in the Applicable Letter of Credit Fee pursuant to the
terms hereof shall become effective immediately upon any change in Rating.

         The Agent shall determine the Applicable Margin from time to time in
accordance with the above table and notify the Company and the Banks of such
determination from time to time. In the event the S&P Rating and the Moody's
Rating correspond to different levels on the above table resulting in different
Applicable Margin determinations, the following provisions shall apply. In the
event the S&P Rating and the Moody's Rating differ by one level, the Applicable
Margin shall be that corresponding to the higher Rating. For example, a "BBB+"
S&P Rating and a "Baa2" Moody's Rating would result in an Applicable Margin
equal to 1.00% for a Loan that has been outstanding for 95 days and which is
then bearing interest at a Eurodollar Rate. In the event the S&P Rating and the
Moody's Rating differ by two levels, the Applicable Margin shall be that
corresponding to that level which is in between the two applicable levels. For
example, a "BBB" S&P Rating and a "Bal" Moody's Rating would result in an

                                   ARTICLE II

                           AMOUNT AND TERMS OF CREDIT

         Section 2.1. Letter of Credit. (a) Subject to the terms and conditions
of this Agreement, the Letter of Credit Bank, on behalf of the Banks, agrees to
issue and amend (including without limitation, to extend or renew) for the
account of the Company, the Letter of Credit as may be requested from time to
time by the Company, from and including the Effective Date to the Termination
Date, up to a maximum Issued Amount at any one time outstanding equal to the
Total Commitments of the Banks minus the sum of (i) the aggregate principal
amount of Loans outstanding, plus (ii) the aggregate principal amount of
Reimbursement Obligations outstanding; provided, however, that the expiration
date of the Letter of Credit shall not extend beyond the Termination Date.

         (b)      Each Bank severally agrees that it shall be absolutely,
unconditionally and irrevocably liable, without regard to the occurrence of any
Default or Event of Default or any condition precedent whatsoever, to the extent
of such Bank's pro rata share of the Total Commitments of the Banks, to
reimburse the Letter of Credit Bank for the amount of each Drawing paid by the
Letter of Credit Bank under the Letter of Credit to the extent such amount is
not reimbursed by the Company in accordance with Section 2.3 hereof. Each Bank's
obligation to reimburse the Letter of Credit Bank pursuant to this Section
2.1(b) shall not be affected by any circumstances, including, without
limitation, (i) any set-off, counterclaim, recoupment, defense or other right
which such Bank may have against the Letter of Credit Bank, the Company, any
direct or indirect beneficiary of the Letter of Credit, the Agent or any other
Person whatsoever; (ii) the occurrence or continuance of a Default or an Event
of Default; (iii) any adverse change in the condition (financial or otherwise)
of the Company; (iv) any breach of this Agreement by the Company, the Agent, the
Letter of Credit Bank or any other Bank; or (v) any other circumstance,
happening or event whatsoever, whether or not similar to any of the foregoing;
provided, however, that the Banks shall not be obligated to reimburse the Letter
of Credit Bank pursuant to this Section 2.1(b) with respect to the Letter of
Credit if (i) the Letter of Credit Bank has made payment pursuant to a Drawing
with respect to the Letter of Credit and the making of such payment constituted
gross negligence or willful misconduct on the part of the Letter of Credit Bank
or (ii) the Letter of Credit Bank increases the Issued Amount of the Letter of
Credit (other than as a result of the automatic reinstatement provisions
contained therein) after an Event of Default has been declared by any Bank or
the Majority Banks pursuant to Article VII hereof and written notice thereof has
been received by the Letter of Credit Bank or after an Event of Default
specified in Section 7.1(c) hereof has occurred. Each Bank's obligations to
reimburse the Letter of Credit Bank shall continue to be effective, or be
reinstated, as the case may be, if at any time payment, or any part thereof, of
any Reimbursement Obligation of the Company is rescinded or must otherwise be
restored or returned by the Letter of Credit Bank upon the insolvency,
bankruptcy, dissolution, liquidation or reorganization of the Company or upon or
a result of the appointment of a receiver, intervenor or conservator of, or
trustee or similar officer for, the Company or any substantial part of its
property, or otherwise, all as though such payment had not been made. Upon
receipt of a notice of its obligation to reimburse the Letter of Credit Bank
prior to 11:00 a.m. (New York time) on a Business Day, a Bank shall make such
reimbursement on such Business Day; if such notice is

                                      -11-
<PAGE>

received after 11:00 a.m. (New York time), reimbursement shall be due on the
next Business Day. The failure of any Bank to honor its obligations hereunder
shall not relieve any other Bank of its duty to honor its obligations hereunder.
Upon the written request of a Bank, the Letter of Credit Bank shall promptly
deliver to such Bank a copy of the Letter of Credit and copies of all material
documents delivered to the Letter of Credit Bank in connection with any Drawing
with respect to the Letter of Credit.

         (c)      Each payment made by a Bank to the Letter of Credit Bank
pursuant to paragraph (b) above shall be treated as the purchase by such Bank of
a participating interest in the Company's Reimbursement Obligation under Section
2.3 hereof in an amount equal to such payment. Each Bank, so long as it has made
the payment required to be made by it pursuant to Section 2.1(b) hereof, shall
share in accordance with its pro rata share of the Total Commitments of the
Banks in any interest which accrues pursuant to Section 2.3(b) hereof. All
amounts recovered by the Agent hereunder and which are applied by the Agent to
the Reimbursement Obligations of the Company under Section 2.3 hereof shall be
distributed by the Agent to the Banks who have made the payments required to be
made by them pursuant to Section 2.1(b) hereof pro rata in accordance with their
respective share of the Total Commitments of the Banks.

         (d)      If and to the extent that any Bank shall fail to make
available to the Letter of Credit Bank the amount required to be paid by such
Bank pursuant to Section 2.1(b) hereof, the Letter of Credit Bank shall be
subrogated to the rights of such Bank under this Agreement to the extent of such
failure and shall thereafter (until such Bank shall make such amount available
to the Letter of Credit Bank) be entitled to receive all amounts owing to such
Bank hereunder and to the percentage of voting rights of such Bank under this
Agreement equal to the percentage the amount such Bank failed to pay bears to
the Issued Amount of the Letter of Credit and the aggregate unpaid principal
amount of all outstanding Reimbursement Obligations and Loans at such time. If
any Bank fails to reimburse the Letter of Credit Bank as provided in Section
2.1(b) hereof or delays in making such payment, such unreimbursed amount shall
bear interest at a rate per annum equal to (i) from the date due to the date
three Business Days after such payment is due, the Federal Funds Rate and (ii)
from the date three Business Days after the date such payment is due to the date
such payment is made, the Base Rate in effect for each such day plus 2%.

         Section 2.2. Method of Issuance of Amendments to the Letter of Credit.

         (a)      Notice of Amendment. The Company shall give the Agent written
notice or telephonic notice confirmed in writing at least three Business Days
prior to the requested date of an amendment to the Letter of Credit, and the
Agent shall give immediate notice thereof to the Letter of Credit Bank and to
each Bank.

         (b)      Issuance. Provided the Company has given the notice prescribed
by Section 2.2(a) and subject to the other terms and conditions of this
Agreement including, without limitation, Section 2.1(a) hereof, the Letter of
Credit Bank shall issue the requested amendment on the date requested by the
Company on behalf of the Banks for the benefit of the stipulated beneficiary and
shall deliver the original of such amendment to the beneficiary. The Letter of
Credit Bank

                                      -12-
<PAGE>

shall deliver a copy of each amendment to the Letter of Credit to the Company
within a reasonable time after the date of issuance thereof.

         (c)      Reporting to Banks. The Agent shall provide such information
concerning the Letter of Credit as any Bank shall reasonably request. The Agent
shall promptly deliver to each Bank copies of the Letter of Credit as issued
hereunder and any amendment thereto and notice of any change in the Issued
Amount (other than a temporary decrease resulting from a Drawing thereunder to
pay accrued interest on the ESOP Notes). Other than as set forth in this
paragraph (c), the Agent shall have no duty to notify the Banks regarding the
issuance or other matters regarding the Letter of Credit issued hereunder. The
failure of the Agent to perform its requirements under this paragraph (c) shall
not relieve the Banks' reimbursement obligations under Section 2.1(b) hereof.

         Section 2.3.    Letter of Credit Reimbursement.

         (a)      Notice of Drawing. The Letter of Credit Bank shall promptly
notify the Company, the Agent and each Bank by telephone, telecopy, telex or
other telecommunication of any Drawing under the Letter of Credit and of the
anticipated payment date. On the payment date, the Letter of Credit Bank shall
confirm to the Company, the Agent and each Bank by telephone or telecopy that
payment of the Drawing is to be made by the Letter of Credit Bank on such date.

         (b)      Payments. The Company hereby agrees absolutely and
unconditionally to pay to the Agent for the account of the Letter of Credit
Bank, in the manner provided in Section 2.3(c):

                  (i)      On each date a Drawing is paid, an amount equal to
         the amount paid by the Letter of Credit Bank under the Letter of
         Credit; and

                  (ii)     If any Drawing shall be reimbursed to the Agent after
         2:00 p.m. (New York time) on the payment date, interest on any and all
         amounts required to be paid pursuant to clause (i) of this Section
         2.3(b) from and after the due date thereof to the date five days after
         such payment is due, payable on demand, at an annual rate of interest
         equal to the Base Rate and from the date five days after the due date
         thereof until payment in full, payable on demand, at an annual rate of
         interest equal to the Base Rate plus 2.00%.

         (c)      Method of Reimbursement. The Company shall reimburse the Agent
(which shall immediately forward such funds, in the form received, to the Letter
of Credit Bank) for each Drawing under the Letter of Credit in the following
manner:

                  (i)      the Company shall immediately reimburse the Agent in
         accordance with Section 2.9 hereof; or

                  (ii)     (A) if the Company has not reimbursed the Agent
         pursuant to subparagraph (i) above and (B) the conditions set forth in
         Section 3.2 hereof have been fulfilled and (C) sufficient funds are
         available within the limits of the amount of Loans that may be borrowed
         as provided in Section 2.5 hereof, with the proceeds of Loans; or

                                      -13-
<PAGE>

                  (iii)    if an Event of Default has occurred and is
         continuing, the Agent may debit any deposit account of the Company
         maintained with the Agent and appropriate and apply an amount of funds
         in such account equal to the Reimbursement Obligations outstanding at
         such time in satisfaction of the Company's obligations set forth in
         subparagraph (i) above.

         (d)      Loans to Fund Drawings. Upon any Drawing, the Agent shall
notify the Banks if the Company has elected to reimburse the Letter of Credit
Bank using the proceeds of Loans. Upon receipt of such notice and if the
conditions set forth in subparagraph (c)(ii) above have been satisfied, each
Bank agrees to deliver to the Agent its pro rata share of the amount of Loans
necessary to reimburse the Letter of Credit Bank for any payment made by the
Letter of Credit Bank pursuant to such Drawing not later than one Business Day
after receipt of such notice. Any funds delivered to the Agent under this
paragraph (d) shall be delivered in the manner set forth in the fourth sentence
of Section 2.6 hereof.

         (e)      Obligations Absolute. The obligations of the Company under
this Article II (and, if applicable in the event of the failure of the Company
to so reimburse the Letter of Credit Bank, subject to the proviso in the second
sentence of Section 2.1(b) hereof, the obligations of the Banks under this
Article II) shall be absolute, unconditional and irrevocable, and shall be
performed strictly in accordance with the terms of this Agreement, under all
circumstances whatsoever, including, without limitation, the following
circumstances:

                  (i)      any lack of validity or enforceability of all or any
         of this Agreement, the Notes, the ESOP Notes, the Indenture and other
         related documents and any other agreements relating to the Letter of
         Credit (the "Related Documents");

                  (ii)     any amendment or waiver of or any consent to or
         departure from the terms of the Related Documents;

                  (iii)    the existence of any claim, set-off, defense or other
         rights which the Company may have at any time against any direct or
         indirect beneficiary of the Letter of Credit, any Bank, the Letter of
         Credit Bank, the Agent or any other Person, whether in connection with
         the Related Documents or any unrelated transaction;

                  (iv)     any statement or any other document presented under
         the Letter of Credit proving to be forged, fraudulent, invalid or
         insufficient in any respect or any statement therein being untrue or
         inaccurate in any respect whatsoever;

                   (v) payment by the Letter of Credit Bank under the Letter of
         Credit against presentation of a sight draft or certificate which does
         not comply with the terms of the Letter of Credit, provided that such
         payment shall not have constituted gross negligence or willful
         misconduct of the Letter of Credit Bank; and

                  (vi)     any other circumstance or happening whatsoever,
         whether or not similar to any of the foregoing, provided that such
         other circumstance or happening shall not

                                      -14-
<PAGE>

         have been the result of gross negligence or willful misconduct of the
         Letter of Credit Bank.

         Section 2.4.    Letter of Credit Bank.

         (a)      Liability of Letter of Credit Bank to Other Banks. The Letter
of Credit Bank shall not be liable to any Bank or to any other participant in
the Letter of Credit for any error in judgment or for any action taken or
omitted to be taken by the Letter of Credit Bank except for actions of the
Letter of Credit Bank constituting gross negligence or willful misconduct.

         (b)      Liability of the Letter of Credit Bank to Company/Banks. The
Company assumes all risks of the acts or omissions of any beneficiary of the
Letter of Credit with respect to its use of the Letter of Credit. Neither the
Letter of Credit Bank, any Bank nor any of their respective officers or
directors shall be liable or responsible to the Company or the Banks for:

                  (i)      the use which may be made of the Letter of Credit or
         for any acts or omissions of any beneficiary in connection therewith;

                  (ii)     the validity, sufficiency or genuineness of documents
         presented under the Letter of Credit even if such documents should in
         fact prove to be in any or all respects invalid, insufficient,
         fraudulent or forged;

                  (iii)    payment by the Letter of Credit Bank against
         presentation of documents which do not comply with the terms of the
         Letter of Credit, including failure of any documents to bear any
         reference or adequate reference to the Letter of Credit; or

                  (iv)     any other circumstances whatsoever in making or
         failing to make payment under the Letter of Credit;

except only that the Company (and, if applicable, the Banks) shall have a claim
against the Letter of Credit Bank to the extent, but only to the extent, of any
direct, as opposed to consequential, damages suffered by the Company (and, if
applicable, the Banks) which were caused by (i) the Letter of Credit Bank's
willful misconduct or gross negligence in determining whether documents
presented under the Letter of Credit comply with the terms of the Letter of
Credit or (ii) the Letter of Credit Bank's willful misconduct or gross
negligence in failing to pay under the Letter of Credit after the presentation
to it by the beneficiary of the Letter of Credit of a sight draft and
certificate strictly complying with the terms and conditions of the Letter of
Credit.

         Section 2.5. Loans. (a) Subject to the terms and conditions hereof,
during the period from the Effective Date to the Termination Date, each Bank
severally and not jointly agrees to make Loans to the Company in an aggregate
principal amount at any one time outstanding up to, but not exceeding, such
Bank's Commitment; provided, however, that any given borrowing of Loans made
pursuant to this Section 2.5 shall not exceed the Available Commitment at the
time of such borrowing; provided, further that Loans shall only be available to
the Company, and the

                                      -15-
<PAGE>

Company agrees that the proceeds of the Loans shall be applied solely, to pay
concurrently with a Drawing under the Letter of Credit the related Reimbursement
Obligation.

         (b)      Each Loan shall mature and become due and payable by the
Company on the date occurring one year after the date the related Drawing under
the Letter of Credit was paid or, if earlier, on the Termination Date.

         Section 2.6. Notice and Place of Borrowing for Loans. The Company shall
give written, facsimile or telephonic (confirmed immediately in writing) notice
to the Agent, such notice to be given not later than 11:00 a.m. New York time on
a Business Day which is at least the Required Number of days prior to each
borrowing of Loans and to contain the date of such borrowing, the amount of such
borrowing, the Interest Rate option selected, and, where applicable, the length
of the Interest Period. Upon receiving notice from the Company, the Agent shall
promptly give written or facsimile notice to each Bank, such notice to contain
the date of such borrowing, the amount to be borrowed from such Bank, the
Interest Rate option selected, and, where applicable, the length of the Interest
Period. Funds are to be disbursed pursuant to this Agreement at the Main Office
of the Agent. Not later than 11:00 a.m. New York time on the date of borrowing
of Loans as specified in the notice from the Agent to the Banks, each Bank shall
have made available at the Main Office of the Agent, in immediately available
funds, the amount of Loans to be advanced by such Bank, and the Agent shall
immediately pay such funds to the Letter of Credit Bank. Unless the Agent shall
have received notice from a Bank prior to the date of any such borrowing that
such Bank will not make available to the Agent such Bank's ratable portion of
such borrowing, the Agent may assume that such Bank has made such portion
available to the Agent on the date of such borrowing in accordance with this
Section 2.6, and the Agent may, in reliance upon such assumption, make available
to the Letter of Credit Bank on such date a corresponding amount. If and to the
extent such Bank shall not have made such ratable portion available to the
Agent, such Bank and the Company severally agree to repay to the Agent
immediately upon demand such corresponding amount together with interest
thereon, for each day from the date such amount is made available to the Letter
of Credit Bank and until the date such amount is repaid to the Agent, at (i)
with respect to the Company, the interest rate applicable at the time to the
type of Loan comprising such borrowing, or (ii) with respect to the Bank, at the
applicable Federal Funds Rate. If such Bank shall repay to the Agent such
corresponding amount, such amount so repaid shall constitute such Bank's Loan as
part of such borrowing for purposes of this Agreement.

         Section 2.7. Evidence of Indebtedness. (a) Each Bank shall maintain in
accordance with its usual practice an account or accounts evidencing the
indebtedness of the Company to such Bank resulting from the Reimbursement
Obligations and each Loan made by such Bank from time to time, including the
amounts of principal and interest payable and paid to such Bank from time to
time hereunder.

         (b)      The Agent shall also maintain accounts in which it will record
(a) the amount of each Reimbursement Obligation and each Loan made hereunder,
the type thereof and the Interest Period with respect thereto, (b) the amount of
any principal or interest due and payable or to become due and payable from the
Company to the Letter of Credit Bank and each Bank

                                      -16-
<PAGE>

hereunder and (c) the amount of any sum received by the Agent hereunder from the
Company and each Bank's share thereof.

         (c)      The entries maintained in the accounts maintained pursuant to
paragraphs (i) and (ii) above shall be prima facie evidence of the existence and
amounts of the obligations therein recorded; provided, however, that the failure
of the Agent or any Bank to maintain such accounts or any error therein shall
not in any manner affect the obligation of the Company to repay the Obligations
in accordance with their terms.

         (d)      Any Bank may request that its Loans be evidenced by a
promissory note or notes in the form of Exhibit A hereto with blanks
appropriately completed (each, a "Note"). In such event, the Company shall
prepare, execute and deliver to such Bank a Note or Notes payable to the order
of such Bank. Thereafter, the Loans evidenced by such Note or Notes and interest
thereon shall at all times (including after any assignment pursuant to Section
10.6) be represented by one or more Notes payable to the order of the payee
named therein or any assignee pursuant to Section 10.6, except to the extent
that any such Bank or assignee subsequently returns any such Note for
cancellation and requests that such Loans once again be evidenced as described
in subsections (a) and (b) above.

         Section 2.8. Interest. The Company shall pay interest on the
outstanding principal amount of each Loan for the period commencing on the date
of such Loan until such Loan shall be paid in full pursuant to the terms of this
Agreement at the rates and times set forth below.

         (a) Interest on Eurodollar Rate Loans. Subject to the provisions of
subsection (c) below, interest on each Eurodollar Rate Loan shall be payable (i)
on the last day of each Interest Period with respect thereto; provided, however,
that if such Interest Period is for a period in excess of three months, then
such interest shall also be payable on the date three months after the first day
of such Interest Period, (ii) on the date of conversion of such Eurodollar Rate
Loan to a Base Rate Loan and (iii) at maturity of such Loan, at an interest rate
per annum during the Interest Period for such Loan equal to the Eurodollar Rate
for the Interest Period in effect for such Eurodollar Rate Loan. Each
determination by the Agent of an interest rate hereunder shall be conclusive and
binding on the Banks and the Company for all purposes, absent manifest error.

         (b)      Interest on Base Rate Loans. Subject to the provisions of
subsection (c) immediately below, interest on each Base Rate Loan shall be
payable monthly in arrears on the last Business Day of each calendar month and
at maturity at an interest rate per annum equal to the Base Rate plus the
Applicable Margin.

         (c)      Interest Upon Event of Default. Any payment of principal or
interest on any Loan which is not paid when due (whether by acceleration or
otherwise), as herein provided, shall bear interest (to the extent permitted by
law) at that rate which is two percent (2%) above the Base Rate in effect on
each day thereafter until paid in full and such interest shall be payable on
demand.

                                      -17-
<PAGE>

         (d)      Prepayment. Upon prepayment of any Loan hereunder, interest
accrued and unpaid on the amount so prepaid shall become due on the date of such
prepayment.

         (e)      Computations. Interest on Base Rate Loans shall be computed on
the basis of a year of 365/366 days and an actual day month. Interest on
Eurodollar Rate Loans shall be computed on the basis of a year of 360 days and
an actual day month.

         Section 2.9. Place of Payment. Each payment (whether required or
voluntary and whether of principal or interest or both) on each Reimbursement
Obligation and Loan and each payment of fees or other amounts owing by the
Company hereunder shall be payable, on or before 11:00 a.m., New York time, on
the due date of each payment, in immediately available funds, to the Agent at
its Main Office at such account as the Agent shall from time to time notify the
Company in writing. The Agent shall then immediately transmit the applicable pro
rata share of such payment so received by the Agent in immediately available
funds to the Letter of Credit Bank or each Bank entitled thereto, as the case
may be, in the manner specified by the Letter of Credit Bank or such Bank. Any
required payment which would otherwise be due on a day not a Business Day shall
be made on the immediately succeeding Business Day.

        Section 2.10. Voluntary Prepayment. The Company may voluntarily prepay,
at any time and from time to time prior to maturity on one Business Day's prior
notice to the Agent, any part or the whole of the principal of the Loans;
provided, however, that any voluntary prepayment shall be in a minimum amount of
$5,000,000. Upon any such prepayment, the Company shall simultaneously pay all
accrued and unpaid interest on the amount of principal voluntarily prepaid.
However, any such prepayment of a Eurodollar Rate Loan shall be made only on the
last day of the Interest Period therefor. All voluntary prepayments provided for
in this Section 2.10 shall be without premium or penalty.

        Section 2.11. Pro Rata Treatment. Except for Section 2.17 hereof, and
except with respect to payments to be made to a Bank pursuant to Sections 2.13,
2.18, 8.1, 8.3 or 10.3 and any other indemnity in favor of a Bank or Banks
hereunder, each borrowing from, payment to, and utilization of and reduction of
the Commitments of, the Banks hereunder shall be prorated among the Banks
according to the respective Commitments of the Banks as the same may be adjusted
from time to time under Section 2.16, 2.17 or 2.18 hereof. Each borrowing of
Loans hereunder shall (in the aggregate) be in the amount necessary to reimburse
the Agent for the account of the Letter of Credit Bank as provided in Section
2.3(c)(i). Except as otherwise provided herein, (i) payments with respect to the
outstanding principal of, or accrued interest on, the Loans shall be made pro
rata to only those Banks that funded such Loans and not to any defaulting Bank
or a Bank not otherwise participating in such Loan and (ii) all payments to be
made by the Company for the account of each of the Banks on account of
principal, interest and fees shall be made without set-off or counterclaim.

        Section 2.12. Initial Determination of Interest Rate and Conversion of
Loans Between Eurodollar Rate and Base Rate. Prior to the initial or any
subsequent borrowing, the Company will specify the Interest Rate to be
applicable to such borrowing, and on any Business Day or Eurodollar Business
Day, as applicable, the Company may convert on a pro rata basis among

                                      -18-
<PAGE>

the Banks any outstanding Base Rate Loans or Eurodollar Rate Loans into the
other type of Loans, subject to the following limitations:

                  (a)      No such conversion of any Eurodollar Rate Loan may be
         made except on the last day of an Interest Period with respect thereto;

                  (b)      The Company shall give the Agent the Required Number
         of days notice for such borrowing or conversion; and

                  (c)      The Company may not select an Interest Period for any
         Eurodollar Rate Loan that extends beyond its maturity date.

If, at the end of an Interest Period of a Eurodollar Rate Loan, the Company has
failed to specify in a timely manner the Interest Rate option applicable to such
Loan for the period after the expiration of the then current Interest Period,
the Company shall be deemed to have selected that such Loan shall be a Base Rate
Loan and, at the end of such Interest Period, such Loan shall automatically
convert to a Base Rate Loan.

        Section 2.13. Failure to Borrow. The Company shall indemnify and hold
harmless each Bank in respect of any funding costs and/or losses in the event
that any borrowing notified to the Banks pursuant to Section 2.6, relative to
Eurodollar Rate Loans, shall not be consummated because of the Company's failure
to satisfy one or more of the applicable conditions precedent in Article III or
because the Company fails to borrow such Loans at the specified time.

        Section 2.14. Fees

         (a)      Letter of Credit Fees. The Company hereby agrees to pay to the
Agent, for the account of the Banks, to be distributed to the Banks pro rata in
accordance with their respective Commitments, a letter of credit fee on the
Issued Amount of the Letter of Credit at a per annum rate equal to the
Applicable Letter of Credit Fee in effect from time to time (as calculated in
accordance with the definition thereof), such fee to be calculated on the Issued
Amount from the date of issuance to the earlier of (x) the date of expiration or
termination of the Letter of Credit or (y) the date of the final Drawing with
respect to the Letter of Credit, based on a year of 360 days and an actual day
month, and payable quarterly in arrears on the last day of each March, June,
September and December during the term of this Agreement and on the Termination
Date, commencing on June 30, 2000.

         (b)      Arrangement Fee. The Company shall pay to the Agent for its
own account an arrangement fee and, if applicable, closing fee as set forth in
the Fee Letter.

         (c)      Fronting Fee. The Company agrees to pay to the Agent, for the
account of the Letter of Credit Bank, a fronting fee as set forth in the Fee
Letter.

        Section 2.15. Termination of Credit Facility. Unless earlier terminated
pursuant to the terms hereof, the Commitments of the Banks, and the Credit
Facility, shall terminate on the Termination Date. Accordingly, the Company
shall pay the entire outstanding principal amount

                                      -19-
<PAGE>

of, and all accrued but unpaid interest on, the Reimbursement Obligations, the
Loans and Notes, together with any and all other amounts owing by the Company to
the Banks, the Letter of Credit Bank and the Agent hereunder or under the Notes,
on the Termination Date.

        Section 2.16. Reductions of Commitments. (a) Optional. The Company shall
have the right at any time or from time to time upon not less than two Business
Days' prior written notice to the Agent to reduce the Total Commitments of the
Banks, in whole or in part, provided that each partial reduction shall be in an
aggregate amount of not less than $1,000,000 and an integral multiple of
$500,000, and shall reduce the respective Commitments of all the Banks
proportionately; provided, however, that the Company shall not reduce the Total
Commitments of the Banks to an amount which is less than the aggregate of (i)
the aggregate principal amount of all Eurodollar Rate Loans having Interest
Periods ending after the effective date of the reduction plus (ii) the Issued
Amount of the Letter of Credit plus (iii) the aggregate outstanding
Reimbursement Obligations; and further, provided, that in no event shall the
Total Commitments of the Banks be reduced to an amount less than $100,000,000,
unless the Total Commitments of the Banks are terminated in full. The Agent
shall give prompt written notice to each Bank of each such reduction. Upon any
optional reduction of the Total Commitments of the Banks, the Company shall
prepay such amount of each Bank's outstanding Loans, if any, as may be necessary
so that after such prepayment the sum of the aggregate unpaid principal amount
of such Bank's Loans, such Bank's pro rata share of unpaid Reimbursement
Obligations, and such Bank's liability in respect of the Letter of Credit does
not exceed the amount of such Bank's Commitment as then reduced. The Company
shall not terminate the Total Commitments of the Banks unless concurrent with
such termination, the Company shall repay all outstanding Loans, Reimbursement
Obligations, Letter of Credit Fees, accrued interest and other amounts owing
hereunder and shall return or cause to be returned to the Letter of Credit Bank
the Letter of Credit marked "cancelled." The Agent shall give prompt written
notice to each Bank of such termination.

         (b)      Mandatory. On each date that the Company repays or prepays a
Loan or Reimbursement Obligation (other than a Reimbursement Obligation incurred
in connection with a "B Drawing" (as defined in the Letter of Credit)), the
Total Commitments of the Banks shall automatically reduce by an aggregate amount
equal to the aggregate principal amount of such Loan being repaid or prepaid,
and shall automatically reduce the respective Commitments of all the Banks
proportionately. On each date on which the Issued Amount of the Letter of Credit
is permanently reduced (other than in connection with a Reimbursement Obligation
that is converted into a Loan), the Total Commitments of the Banks shall
automatically reduce in an amount equal to the amount of such reduction in the
Issued Amount, and shall automatically reduce the respective Commitments of all
the Banks proportionately.

         Section 2.17. Substitution of Banks.

         Section 2.17.1. (a) If any Bank shall default in the performance of its
Commitment, whether in whole or in part, or shall have appointed for it a
receiver or conservator at the direction or request of any regulatory agency or
authority, then:

                  (i)      such default shall not relieve any other Bank of its
         Commitment; and

                                      -20-
<PAGE>

                  (ii)     the Company may, with the prior written approval of
         the Agent (such approval not to be unreasonably withheld) and the
         Letter of Credit Bank and shall, at the written request of the Letter
         of Credit Bank, with the prior written approval of the Agent (such
         approval not to be unreasonably withheld), terminate the Commitment of
         such defaulting Bank and arrange for the Commitment of the defaulting
         Bank to be assigned to one or more of the other Banks, and to the
         extent that such other Banks will not take over such Commitment,
         arrange for its assumption by one or more banks which are not at that
         time parties hereto, each of which banks shall, except as otherwise
         provided herein, upon execution and delivery to the Company of a
         counterpart hereof, become a Bank hereto to the extent of the
         Commitment taken over by it.

         (b)      If any Bank shall cease to have a long-term debt rating of
BBB- or higher by S&P and Baa3 or higher by Moody's (each, a "Downgraded Bank")
such Downgraded Bank shall immediately notify the Agent and Letter of Credit
Bank thereof and the Letter of Credit Bank may (i) with the prior written
approval of the Agent and the Company (such approvals not to be unreasonably
withheld), terminate the Commitment of such Downgraded Bank and arrange for the
Commitment of such Downgraded Bank to be assigned to one or more of the other
Banks, and to the extent that such other Banks will not take over such
Commitment, arrange for its assumption by one or more banks which are not at
that time parties hereto, each of which banks shall, except as otherwise
provided herein, upon execution and delivery to the Company of a counterpart
hereof, become a Bank hereto to the extent of the Commitment taken over by it or
(ii) if such Downgraded Bank's Commitment has not been assigned pursuant to
clause (i) above, immediately require such Downgraded Bank to fund (and each
Downgraded Bank hereby agrees in such event to fund) any unused portion of its
Commitment by payment of such amount to the Agent for deposit in an account in
the name of the Letter of Credit Bank, maintained at the Main Office or such
other office as the Agent may specify by notice to such Downgraded Bank and the
Letter of Credit Bank (each, a "Downgrade Collateral Account").

      Section 2.17.2. Loans previously made hereunder by a Downgraded Bank,
defaulting or withdrawing Bank, or any portion thereof, which are included in
the Commitment taken over by any other Bank or Banks or by a bank or banks not
then parties hereto, shall be prepaid by the Company without penalty or premium.

      Section 2.17.3. From time to time, the Company may with the written
consent of the Letter of Credit Bank replace a non-defaulting Bank (the
"Replaced Bank") with another financial institution (or institutions) desiring
to be a Bank hereunder (the "New Bank(s)") and/or with one or more Banks already
a party hereto ("Existing Bank(s)") so long as (a) the Replaced Bank consents in
writing to such replacement and receives all amounts owing to such Replaced Bank
hereunder on the effective date of such replacement, (b) the New Bank(s) and/or
Existing Bank(s), as the case may be, assume(s) all of the obligations of a Bank
hereunder having a Commitment equal to the Replaced Bank's by executing, in the
case of a New Bank(s), a letter agreement in substantially the form of Exhibit
B-1 attached hereto or, in the case of an Existing Bank(s), a letter agreement
in substantially the form of Exhibit B-2 hereto, (c) the Commitment(s) of the
New Bank(s), together with the additional Commitment(s) of the Existing Bank(s)
assumed by the Existing Bank(s) pursuant hereto, is equal to the Commitment of
the Replaced Bank and (d) the Company and the Letter of Credit Bank acknowledge
and consent

                                      -21-
<PAGE>

that the New Bank(s) shall become a Bank hereunder (and/or that the Existing
Bank(s) shall have an additional Commitment hereunder equal to that of the
Replaced Bank) by signing the respective acknowledgments contained in the
appropriate letter agreement referred to in subparagraph (c) above.

      Section 2.17.4. Upon the increase in any Bank's Commitment or any bank or
banks becoming a party to this Agreement as herein provided, the Company shall
immediately furnish to all Banks which are then parties hereto notice of (a) the
increased Commitment of such Bank, or (b) the names and addresses of such bank
or banks together with the amount of the Commitment of each such bank or banks.

      Section 2.17.5. The respective amounts of the Commitments hereunder shall
be adjusted from time to time to reflect any changes made pursuant to this
Section 2.17 and notice of such adjustments shall be given by the Company at the
time thereof to each Bank or bank then a party hereto. Such adjusted amounts of
Commitments shall thereupon become the basis for pro rata treatment under
Section 2.11 of this Agreement.

      Section 2.17.6. Upon the termination in whole of the Commitment of any
Bank, and the prepayment of all Loans previously made under such Commitment, all
as provided in this Section 2.17, such Bank shall cease to be a party to this
Agreement except as otherwise provided herein.

      Section 2.17.7. If any Downgraded Bank shall be required pursuant to
2.17.1(b) above to fund the unused portion of its Commitment into a Downgrade
Collateral Account, then the Agent shall apply the monies in the Downgrade
Collateral Account applicable to the Loans and Reimbursement Obligations payable
by such Downgraded Bank pursuant to Article II at the times for, in the manner
required in respect of and subject to the conditions precedent to such Loan or
Reimbursement Obligation, as applicable. The deposit of monies in such Downgrade
Collateral Account by any Downgraded Bank shall not constitute a Loan pursuant
to Section 2.5 (and such Downgraded Bank shall not be entitled to interest on
such monies except as provided below in this Section 2.17.7) unless and until
(and then only to the extent that) such monies are used to make Loans or fund
Reimbursement Obligations. Proceeds in such Downgrade Collateral Account shall
be invested in Permitted Investments, as directed by the applicable Downgraded
Bank by written notice to the Letter of Credit Bank and the Agent, the income of
which shall be for the account of such Downgraded Bank. The income that has
accrued from such investments and received by the Letter of Credit Bank shall be
released to such Downgraded Bank on the last Business Day of each month. Unless
required to be released by the following sentence, any amounts received by the
Agent in respect of the Commitment of a Downgraded Bank (whether as a repayment
of Loans or Reimbursement Obligations or otherwise) shall be deposited in the
Downgrade Collateral Account for such Downgraded Bank. All amounts remaining in
such Downgrade Collateral Account shall be released to such Downgraded Bank no
later than the Business Day immediately following the earliest of (x) the
effective date of any replacement of such Downgraded Bank or removal of such
Downgraded Bank as a party to this Agreement, (y) the date on which such
Downgraded Bank shall furnish the Agent and the Letter of Credit Bank with
confirmation that such Downgraded Bank shall have long-term debt ratings at
least equal to the Required Ratings and (z) the Business Day

                                      -22-
<PAGE>

immediately following the expiration of the Termination Date. As used in this
Section 2.17 "Permitted Investments" means investments in direct obligations of
the United States of America or of any agency or instrumentality thereof whose
obligations constitute full faith and credit obligations of the United State of
America provided that any such obligation matures within thirty days from the
date of purchase.

        Section 2.18. Capital Requirements. If, as a result of the adoption
after the date of this Agreement, of any applicable law, rule or regulation
affecting capital adequacy or capital maintenance, or any change after the date
of this Agreement in the interpretation or administration of any law, rule or
regulation affecting capital adequacy or capital maintenance in existence as of
the date hereof by any governmental authority, central bank or comparable agency
charged with the interpretation or administration thereof, or compliance by such
Bank or the Letter of Credit Bank with any request or directive affecting
capital adequacy or capital maintenance (whether or not having the force of law)
of any such authority, central bank or comparable agency, any Bank or the Letter
of Credit Bank determines that such adoption, change or compliance has or would
have the effect of reducing the rate of return on such Bank's or the Letter of
Credit Bank's capital as a consequence of its Commitment or Loans or its
commitment to issue, participate in or maintain the Letter of Credit to a level
below that which such Bank or the Letter of Credit Bank could have achieved but
for such adoption, change or compliance (taking into consideration such Bank's
or the Letter of Credit Bank's policies with respect to capital adequacy) by an
amount deemed by such Bank or the Letter of Credit Bank to be material, such
Bank or the Letter of Credit Bank shall give prompt notice to the Company and
the Agent, and then from time to time, within 15 days after submission by such
Bank or the Letter of Credit Bank to the Company (with a copy to the Agent) of a
written request therefor, the Company shall pay to such Bank or the Letter of
Credit Bank such additional amount or amounts as will compensate such Bank or
the Letter of Credit Bank for such reduction. Any request submitted by a Bank or
the Letter of Credit Bank to the Company pursuant to this Section 2.18 shall
contain such calculations of the amounts requested therein as such Bank or the
Letter of Credit Bank shall deem reasonable in view of its customary practices,
and shall be submitted as soon as practicable, but in any event the initial
request shall be submitted not more than 90 days after such Bank or the Letter
of Credit Bank becomes aware of the event by reason of which such request is
being submitted. Subsequent requests by such Bank shall be submitted quarterly.
If any Bank requests payment of any amount from the Company pursuant to this
Section 2.18, the Company may, pursuant to arrangements and documentation
satisfactory to the Company and the Agent, prepay the outstanding Loans, fees,
and any other amounts due to such Bank in full and terminate the Commitment of
such Bank and the Company shall, with the prior written consent of the Letter of
Credit Bank at its option, either arrange for all or part of the Commitment of
such Bank to be taken over by one or more of the other Banks or, to the extent
such other Banks do not take over such Commitment or part thereof, arrange for
it to be taken over in whole or in part by a bank or banks not a party hereto,
each of which banks shall, except as otherwise provided herein upon execution
and delivery to the Company of a counterpart hereof, become a full party hereto
to the extent of the Commitment taken over by it. Upon any bank or banks
becoming a party to this Agreement as herein provided, the Company shall
immediately furnish to all Banks which are then parties hereto the names and
addresses of such bank or banks together with the amount of the Commitment of
each such bank or banks. The respective amounts of the Commitments hereof shall
be adjusted from time to time to reflect

                                      -23-
<PAGE>

any changes made pursuant to this Section 2.18 and notice of such adjustments
shall be given by the Company at the time thereof to each Bank then a party
hereto. Such adjusted amounts of Commitments shall thereupon become the basis
for pro rata treatment under Section 2.11 of this Agreement. Upon the
termination in whole of the Commitment of any Bank, and the prepayment of all
Loans previously made under such Commitment, all as provided in this Section
2.18, such Bank shall cease to be a party to this Agreement except as otherwise
provided herein.

        Section 2.19. Change in Control. Upon the occurrence of a Change in
Control and at any time during the ninety (90) day period thereafter, the
Company shall, upon the written request of the Agent, deposit with the Agent, in
an interest bearing account, as collateral, Dollars in an amount equal to the
sum of the Issued Amount, outstanding Reimbursement Obligations and the
aggregate outstanding principal amount of any Loans owing under this Agreement
(the "Change in Control Collateral"). The Change in Control Collateral shall be
applied against amounts due to the Agent, the Letter of Credit Bank and the
Banks resulting from any Drawing. All Change in Control Collateral shall be held
in the account with the Agent until the expiration of the Letter of Credit and
payment of all Reimbursement Obligations and Loans in connection therewith, at
which time the remaining Change in Control Collateral and any interest accrued
thereon shall be returned to the Company.

         Section 2.20. Administration Fees. The Company agrees to pay to the
Agent an annual administrative fee to compensate the Agent for the
administration of the Credit Facility and for other services, as set forth in
the Fee Letter.

                                   ARTICLE IV

                         REPRESENTATIONS AND WARRANTIES

         The Company hereby represents, covenants and warrants to the Agent, the
Letter of Credit Bank and each of the Banks as follows:

         Section 4.1.     Organization; Standing, Etc. The Company is a
corporation duly organized and existing under the laws of the State of Delaware,
has the corporate power to own its property and carry on its business as being
conducted, and is duly qualified to do business as a foreign corporation and is
in good standing in every jurisdiction in which the nature of the business
conducted by it makes such qualification necessary.

         Section 4.2.      Authorization; No Violation. The execution, delivery
and performance by the Company of this Agreement (i) has been duly authorized by
all necessary corporate action and does not require any consent or approval,
authorization, permit or license from any federal, state or other regulatory
authority which has not been obtained, or violate any law, regulation, order,
judgment, decree or determination having applicability to the Company or its
organizational documents, or result in a breach of, or constitute a default
under any existing indenture or credit agreement or any other agreement or
instrument to which the Company is a party or by which its properties may be
bound or affected except where the failure to have such consent or approval or
such violation, breach or default could not reasonably be expected to result in
a material adverse effect on the business, financial condition or results of
operations of the Company and its Subsidiaries taken as a whole, and (ii) will
not conflict with, or result in a breach of the terms, conditions or provisions
of, or constitute a default under, the Certificate of Incorporation or Bylaws of
the Company or of any agreement or instrument to which the Company is now a
party, which breach would have a material adverse effect on the business,
financial condition or results of operations of the Company and its Subsidiaries
taken as a whole.

         Section 4.3.      Enforceability. This Agreement has been duly executed
and delivered by the Company and constitutes a legal, valid and binding
obligation of the Company enforceable against the Company in accordance with its
terms, except as enforcement may be limited by applicable bankruptcy,
insolvency, fraudulent conveyance, reorganization, moratorium or other laws
affecting the enforcement of creditors' rights generally and by general
equitable principles (whether enforcement is sought by proceedings in equity or
at law).

         Section 4.4.      Financial Statements. The Company has furnished the
Banks with the following financial statements, identified by the certificate of
a principal financial officer of the Company: (i) balance sheets of the Company
as at June 30, 1999 and March 31, 2000, and income and reinvested earnings
statements of the Company for the fiscal year or fiscal quarter, as the case may
be, ended on such dates, respectively, certified, in the case of financial
statements for the year ended June 30, 1999, by Arthur Andersen LLP. Such
financial statements are true and correct and have been prepared in accordance
with GAAP (except, in the case of the quarterly financial statements, the
absence of complete footnotes and subject to normal year-end audit adjustments).
The balance sheets and their accompanying notes present fairly the condition of
the Company as of the dates thereof, and the income and reinvested

business, financial condition or results of operations of the Company and its
Subsidiaries taken as a whole since March 31, 2000.

         Section 4.5.      Litigation. There is no action or proceeding pending
or threatened against the Company before any court or administrative agency
which, in the reasonable opinion of the Company, is likely to be determined in a
manner which would result in any material adverse change in the business,
financial condition or results of operations of the Company and its Subsidiaries
taken as a whole and the Company is not in default with respect to any order,
writ, injunction or decree of any court or administrative agency, which would
have a material adverse effect on the Company and its Subsidiaries taken as a
whole.

         Section 4.6.      Business; Status as Air Carrier. (a) The Company is a
duly certificated air carrier and there are in force any certificates or other
appropriate authority issued by appropriate governmental authorities necessary
to authorize the Company to engage in intrastate, interstate, overseas and
foreign air transportation of persons, property and mail over the routes
operated by the Company; and

                   (b)     no proceedings are pending or threatened, by or
         before any public body, agency or authority, domestic or foreign,
         including but not limited to proceedings to alter, amend, modify,
         suspend or revoke such certificates in whole or in part, which might
         seriously affect adversely the income from, title to, or possession of,
         any of the properties of the Company, to an extent which would
         constitute a material adverse change in the business or condition of
         the Company.

         Section 4.7.      Funded Debt. The Company does not have outstanding
any Funded Debt except as set forth on Schedule I to this Agreement; and there

all federal income tax returns which are required to be filed, and has paid all
taxes as shown on said returns and on all assessments received by it to the
extent that such taxes (other than those which the Company is contesting in good
faith by appropriate proceedings being diligently conducted) have become due.

         (b)      The federal income tax liability of the Company has been
finally determined by the Internal Revenue Service and satisfied for all fiscal
years prior to and including the fiscal year ended June 30, 1992.

required to be filed have been duly filed, and all taxes and government charges

diligently conducted) upon the Company, its assets, income or franchises which
are due and payable have been paid.

Letter of Credit are intended to be used solely to pay the principal of and
interest and premium on the ESOP Notes and the proceeds of any Loan will be used

list of all Subsidiaries as of the date hereof, all of which are corporations
duly incorporated, in good standing and with corporate power to transact the
business presently conducted by them. Except as disclosed in Schedule II, the
Company owns, directly or indirectly through one or more Subsidiaries, all the
shares of each of the Subsidiaries (except directors' qualifying shares, if

are free and clear of all liens and rights of others whatsoever.

        Section 4.13.      ERISA. The Company and each Subsidiary have met their
minimum funding requirements under ERISA with respect to all their employee

any entity succeeding to any or all of said Corporation's functions under ERISA)
under ERISA in connection with any such plan.

        Section 4.14.      Environmental Matters. The Company and its

and local environmental laws, regulations and ordinances governing their
respective business, properties or assets with respect to discharges into the

otherwise) of the Company and its Subsidiaries taken as a whole. All licenses,

Subsidiaries under any federal, state or local environmental laws, regulations
or ordinances have been secured, and the Company and each Subsidiary are in

against loss or damage of the kind customarily insured against by such
corporations, and carry adequate liability insurance and other insurance of a
kind generally carried by corporations engaged in the same or similar businesses
similarly situated; provided, however, that nothing herein contained shall be
construed to mean that a deductibility clause in any such insurance, which, in
effect, results in self-insurance of a level or portion of losses considered
reasonable by the Company's management, shall render such insurance inadequate;
and provided, further, that in the case of a lease to the United States
Government or an agency thereof of any aircraft or other property, indemnity
therefrom by the United States Government will be considered adequate insurance
against the risks that are the subject of any such indemnity.

each of its Airline Subsidiaries to, duly file all federal income tax returns

         determine how the conclusions on such statement were arrived at,
         certified by an authorized financial officer of the Company as accurate
         in all material respects;

                   (c)     Copies of all financial statements, reports and

times and as often as such Bank may reasonably request. This covenant shall be
subject to applicable governmental and industrial security regulations.

         Section 5.6.      Security. In the event the Company secures by

         which failure has resulted in a material liability for excise tax under
         Section 4971 of said Code; or any of its plans aforesaid shall be the
         subject of voluntary or involuntary termination proceedings which may
         result in an uninsured payment or repayment liability of the respective
         corporation to the Pension Benefit Guaranty Corporation (or any entity
         succeeding to any or all of its functions under said Act) in an amount
         which is material in relation to the net worth of the Company;

then, in the event that an Event of Default under (a) or (b) above should occur,
any Bank may, at its option, by a written notice to the Company with copies to
the Agent and to each other Bank, if such Event of Default be continuing at the
time such notice is received by the Company, either: (i) declare the obligation
of such Bank to extend credit to the Company hereunder to be immediately
terminated, whereupon such obligation shall terminate (provided that any such
termination shall not affect such Bank's obligations under Section 2.1 hereof);
or (ii) declare

                                      -35-
<PAGE>

any Loan and Reimbursement Obligations held by it to be forthwith due and
payable whereupon such Loans and Reimbursement Obligations, with accrued
interest thereon, shall become forthwith due and payable without presentment,
demand, protest or any other notice of any kind, all of which are hereby
expressly waived by the Company; or (iii) demand that the Company immediately
deposit as cash collateral with the Agent, for such Bank's account, an amount
equal to such Bank's pro rata share of the Issued Amount of the Letter of
Credit; or (iv) all of the foregoing. In the event that an Event of Default
under (a), (b), or (d) through (i) above should occur, if such Event of Default
be continuing, the Majority Banks may, at their option, by written notice to the
Company, exercise the remedies listed in (i), (ii), (iii) and/or (iv) above and
may direct the Letter of Credit Bank to deliver the Notice of Non-Reinstatement
as provided in the Letter of Credit on behalf of all the Banks. In the event
that an Event of Default under (c) above should occur, the Total Commitments of
the Banks shall automatically terminate and the principal of and accrued
interest on the Loans then outstanding, all unpaid Reimbursement Obligations and
any accrued fees, together with an amount equal to the Issued Amount of the
Letter of Credit (without regard to whether a draft has been presented under the
Letter of Credit) to be held as cash collateral by the Agent for the
Reimbursement Obligations of the Company with respect to the Letter of Credit,
shall automatically become due and payable, without protest, presentment, notice
or demand, all of which are expressly waived by the Company and the Majority
Banks may direct the Letter of Credit Bank to deliver the Notice of
Non-Reinstatement as provided in the Letter of Credit.

                                  ARTICLE VIII

                                YIELD PROTECTION

         Section 8.1.      Increased Cost of Eurodollar Rate Loans. (a) If, as a
result of any change after the date of this Agreement in (including the
introduction of any new) applicable United States, state or foreign laws or
regulations or the adoption or making of any interpretations, directives or
requests thereof or thereunder by any court or governmental authority charged
with the interpretation or administration thereof, one or more of the following
events occur (herein called "Increased Cost Changes"):

                   (i)     the basis of taxation of payments to any Bank of the
         principal of or interest on any Eurodollar Rate Loan or any other
         amounts payable under this Agreement in respect thereof (other than
         taxes imposed on the aggregate net income of such Bank or of its
         Eurodollar Lending Office by the jurisdiction in which the Bank has its
         principal office or such Eurodollar Lending Office) is changed; or

                  (ii)     any reserve, special deposit or similar requirements
         against the assets of, deposits with or for the account of, or credit
         extended by, any Bank are imposed, modified or deemed applicable; or

                 (iii)     any other condition affecting this Agreement or any
         Eurodollar Rate Loan is imposed on any Bank or (in the case of
         Eurodollar Rate Loans) the London interbank market;

                                      -36-
<PAGE>

and such Bank determines that, by reason thereof, the cost to such Bank of
making or maintaining any of the Eurodollar Rate Loans is increased by an amount
reasonably determined by such Bank, or any amount receivable by such Bank
hereunder in respect of any of the Eurodollar Rate Loans is reduced by an amount
reasonably determined by such Bank (such increases in cost and reductions in
amounts receivable being herein called "Increased Costs"), then the Company
shall pay to such Bank on the next interest payment date for the affected
Eurodollar Rate Loans such additional amount or amounts (which shall be set
forth in a notice from such Bank to the Company stating the cause and amount of
such Increased Costs) as will compensate such Bank for such Increased Costs.
Each Bank will immediately notify the Company of any event of which such Bank
has knowledge that will entitle such Bank to compensation pursuant to this
Section 8.1(a) and will exercise reasonable diligence to designate a different
Eurodollar Lending Office, and/or take other measures which will avoid the need
for such compensation for Increased Costs and will not result in material cost
to such Bank, or be otherwise disadvantageous (in such Bank's sole
determination) to such Bank.

         (b)      Without limiting the effect of the foregoing, the Company
shall pay (without duplication as to amounts paid under Section 8.1(a) hereof)
to any Bank on each interest payment date as to Eurodollar Rate Loans so long as
such Bank may be required to maintain reserves against "Eurocurrency
liabilities" under Regulation D of the Board of Governors of the Federal Reserve
System an additional amount (determined by such Bank and notified to the Company
through the Agent) equal to the sum of the products of the following for each
Eurodollar Rate Loan for each day on which such Bank is required to maintain
such reserve during the Interest Period for such Loan for which interest is
being paid:

                   (i)     the principal amount of such Eurodollar Rate Loan
         outstanding on such day; times

                  (ii)     the remainder of (x) a fraction the numerator of
         which is LIBOR (expressed as a decimal) used to determine the
         Eurodollar Rate for such Eurodollar Rate Loan for such Interest Period
         as provided in this Agreement and the denominator of which is one minus
         the effective rate (expressed as a decimal) at which such reserve
         requirements are imposed on such Bank on such day minus (y) such
         numerator; times

                 (iii)     1/360.

         (c)      Determination by any Bank for purposes of this Section 8.1 of
the effect of any Increased Cost Changes on such Bank's costs of making or
maintaining Eurodollar Rate Loans or on amounts receivable by it in respect of
Eurodollar Rate Loans, and of the additional amounts required to compensate such
Bank in respect thereof, shall be conclusive, provided that such determinations
are made reasonably and in good faith.

         (d)      If the Company is required to pay additional amounts to any
Bank under paragraph (a) or (b) of this Section 8.1, the Company may (in
addition to paying such additional amounts to such Bank) at the Company's option
at any time, subject to the provisions of Section 8.3 hereof, convert all of the
Eurodollar Rate Loans of such Bank which are affected by such Increased Costs to
Base Rate Loans in accordance with this Agreement.

                                      -37-
<PAGE>

         Section 8.2.      Change of Law. Notwithstanding any other provision
herein, in the event that any change in applicable law, rule or regulation or in
the interpretation or administration thereof (including the issuance of any new
law, rule, regulation or interpretation, or any new administration thereof), of
or in any jurisdiction whatsoever, shall make it unlawful for any Bank to make
or maintain a Eurodollar Rate Loan (or to convert Base Rate Loans into
Eurodollar Rate Loans), or shall materially restrict the authority of any Bank
to purchase or sell, or to take deposits of, Eurodollars, then the obligation of
such Bank to make Eurodollar Rate Loans (and the right of the Company to convert
Base Rate Loans of such Bank into Eurodollar Rate Loans) shall be suspended for
the duration of such illegality or restriction and the Company shall forthwith
convert all Eurodollar Rate Loans of such Bank then outstanding to Base Rate
Loans in accordance with the terms of this Agreement.

         Section 8.3.      Funding Losses. The Company shall indemnify each Bank
against, and reimburse such Bank on demand for, any loss or expense incurred or
sustained by such Bank, as reasonably determined by such Bank, as a result of
any payment or prepayment (whether by reason of a voluntary prepayment by the
Company or by reason of a mandatory prepayment of the Loans by reason of an
Event of Default or other mandatory prepayment provision relating to all
outstanding Loans set forth herein) or conversion of a Eurodollar Rate Loan made
by such Bank on a day other than the last day of an Interest Period for such
Loan.

         Section 8.4.      Increased Cost of Maintaining Letter of Credit. (a)
If, as a result of any change after the date of this Agreement in (including the
introduction of any new) applicable United States, state or foreign laws or
regulations or the adoption or making of any interpretations, directives or
requests thereof or thereunder by any court or governmental authority charged
with the interpretation or administration thereof, one or more of the following
events occur (herein called "Increased Letter of Credit Cost Changes"):

                   (i)     any reserve, special deposit or similar requirements
         against the Letter of Credit are imposed, modified or deemed
         applicable; or

                  (ii)     any other condition regarding the issuance,
         maintenance of, or participation in the Letter of Credit are imposed
         upon the Letter of Credit Bank or any other Bank, and the result of any
         such event shall be to increase the cost to the Letter of Credit Bank
         or such other Bank of issuing, maintaining, or participating in the
         Letter of Credit;

and the Letter of Credit Bank or such other Bank determines that, by reason
thereof, the cost to the Letter of Credit Bank or such Bank of issuing,
maintaining, or participating in the Letter of Credit is increased by an amount
reasonably determined by the Letter of Credit Bank or such Bank, then, within
fifteen (15) days of the Letter of Credit Bank or such Bank obtaining knowledge
of such change in law, regulation or interpretation thereof, the Letter of
Credit Bank or such Bank shall so notify the Company, and upon receipt of such
notice from the Letter of Credit Bank or such Bank, the Company shall promptly
pay to the Letter of Credit Bank or the Bank, from time to time as specified by
the Letter of Credit Bank or the Bank, additional amounts which shall be
sufficient to compensate the Letter of Credit Bank or such Bank for such
increased cost.

                                      -38-
<PAGE>

         (b)      Determinations by the Letter of Credit Bank or any Bank for
purposes of this Section 8.4 of the effect of any Increased Letter of Credit
Cost Change, and of the additional amounts required to compensate the Letter of
Credit Bank or such Bank in respect thereof, shall be conclusive, provided that
such determinations are made reasonably and in good faith.

         Section 8.5.      Mandatory Repayment or Conversion on Certain Events.
On the last day of an Interest Period during which any Orderly Replacement Event
occurs (which relates to all Banks) and no later than four Eurodollar Business
Days after any Immediate Replacement Event relating to one or more Banks, all
outstanding Eurodollar Rate Loans of such Banks shall, at the option of the
Company, be either: (a) prepaid in full by the Company, together with any
accrued and unpaid interest thereon, or (b) converted to Base Rate Loans. Each
Bank shall promptly notify the Company and Agent of any Immediate Replacement
Event and any Orderly Replacement Event known to such Bank.

         Section 8.6.    Survival.  The obligations of the Company under
Sections 8.1 through 8.4 of this Agreement shall survive the repayment of the
Loans and all Reimbursement Obligations and the cancellation of the Notes.

                                   ARTICLE IX

                                    THE AGENT

         Section 9.1.      Authorization and Action. Each Bank hereby appoints
and authorizes the Agent to take such action as agent on its behalf and to
exercise such powers under this Agreement and the Notes as are delegated to it
as Agent by the terms hereof and thereof, together with such powers as are
reasonably incidental thereto, and the Agent hereby accepts such authorization
and appointment. As to any matters not expressly provided for by this Agreement
and the Notes or provided for with specific reference to this Section 9.1
(including, without limitation, enforcement or collection of the Obligations),
the Agent shall not be required to exercise any discretion or take any action,
but shall be required to act or to refrain from acting (and shall be fully
protected in so acting or refraining from action) upon the instructions of the
Majority Banks and such instructions shall be binding upon all Banks and all
holders of the Notes; provided, however, that the Agent shall not be required to
take any action which exposes the Agent to liability or which is contrary to
this Agreement or the Notes or applicable law. As to any provisions of this
Agreement under which action may be taken or approval given by the Majority
Banks, the action taken or approval given by the Majority Banks shall be binding
upon all Banks to the same extent and with the same effect as if each Bank had
joined therein. The Agent shall be entitled to rely upon any note, notice,
consent, certificate, affidavit, letter, teletype message, facsimile
transmission, statement, order or other document believed by it to be genuine
and correct and to have been signed or sent by the proper Person or Persons and,
in respect of legal matters, upon the opinion of counsel selected by the Agent.
The Agent may deem and treat the payee of any Note as the owner thereof for all
purposes hereof unless and until a written notice of the assignment or transfer
thereof shall have been filed with the Agent. Any request, authority or consent
of any Person who at the time of making such request or giving such authority or
consent is the holder of any Note shall be conclusive and binding on any

                                      -39-
<PAGE>

subsequent holder, transferee or assignee of such Note or of any note or notes
issued in exchange therefor. The relationship between the Agent and the Banks is
and shall be that of agent and principal only, and nothing contained in this
Agreement or any other Loan Document shall be construed to constitute the Agent
as a trustee or fiduciary for any Bank or the Company.

         Section 9.2.      Agent's Reliance, Etc. Neither the Agent nor any of
its directors, officers, agents or employees shall be liable to any Bank for any
action taken or omitted to be taken by it or by such directors, officers, agents
or employees under or in connection with this Agreement or the Notes, except for
its or their own gross negligence or willful misconduct. Without limitation of
the generality of the foregoing, the Agent: (i) may consult with legal counsel,
independent public accountants and other experts selected by it and shall not be
liable to any Bank for any action taken or omitted to be taken in good faith by
it in accordance with the advice of such experts; (ii) makes no warranty or
representation to any Bank and shall not be responsible to any Bank for any
statements, warranties or representations made in or in connection with this
Agreement or the Notes; (iii) shall not have any duty to ascertain or to inquire
as to the performance or observance of any of the terms, covenants or conditions
of this Agreement or the Notes on the part of the Company or to inspect the
property (including the books and records) of the Company; (iv) shall not be
responsible to any Bank for the due execution, legality, validity,
enforceability, genuineness, sufficiency or value of this Agreement or the
Notes, or any other instrument or document furnished pursuant thereto; and (v)
shall incur no liability under or in respect to this Agreement or the Notes by
acting upon any notice, consent, certificate or other instrument or writing
(which may be by facsimile transmission, cable or telex) believed by it to be
genuine and signed or sent by the proper party or parties.

         Section 9.3.      Agent and Affiliates. With respect to its Commitment,
the Loans made by it and the Notes issued to it, if any, the Agent shall have
the same rights and powers under this Agreement as any other Bank and may
exercise the same rights and powers under this Agreement as any other Bank and
may exercise the same as though it were not the Agent; and the term "Bank" or
"Banks" shall, unless otherwise expressly indicated, include the Agent in its
individual capacity. Unrelated to its role as Agent as set forth herein, the
Agent and its affiliates may accept deposits from, lend money to, and generally
engage in any kind of business with, the Company, and any Person who may do
business with or own securities of the Company, all as if it were not the Agent
and without any duty to account therefor to the Banks.

         Section 9.4.      Representations of the Banks. Each Bank acknowledges
that it has, independently and without reliance upon the Agent, or any affiliate
or subsidiary of the Agent, the Letter of Credit Bank, or any other Bank and
based on the financial statements referred to in Section 4.4 hereof and such
other documents and information as it has deemed appropriate, made its own
credit analysis and decision to enter into this Agreement; and that such Bank
has actively engaged in the negotiation of all of the terms of this Agreement.
Each Bank also acknowledges that it will, independently and without reliance
upon the Agent, the Letter of Credit Bank or any other Bank and based on such
documents and information as it shall deem appropriate at the time, continue to
make its own credit decisions in taking or not taking action under this
Agreement or the Notes. The Agent has no duty or responsibility, either
initially or on a continuing basis, to provide any Bank with any credit or other
information with respect to the Company whether coming into its possession as of
the date of this Agreement or at any time

                                      -40-
<PAGE>

thereafter, or to notify any Bank of any Event of Default except as provided in
Section 9.5 hereof. This Agreement and all instruments or documents delivered in
connection with this Agreement have been reviewed and approved by such Bank and
such Bank has not relied on the Agent as to any legal or factual matter in
connection therewith or in connection with the transactions contemplated
thereunder.

         Section 9.5.      Events of Default. In the event of the occurrence of
any Default or Event of Default, any Bank knowing of such event may (but shall
have no duty to), or the Company pursuant to Section 5.7 hereof shall, give the
Agent and Letter of Credit Bank written notice specifying such Event of Default
or other event and expressly stating that such notice is a "notice of default".
Neither the Agent nor the Letter of Credit Bank shall be deemed to have
knowledge of such events unless the Agent or Letter of Credit Bank, as
applicable, has received such notice. In the event that the Agent receives such
a notice of the occurrence of an Event of Default, the Agent shall give written
notice thereof to the Banks. The Agent shall take such action with respect to
such Default or Event of Default as shall be reasonably directed in writing by
the Majority Banks; provided, however, that, unless and until the Agent shall
have received such directions, the Agent may take such action, or refrain from
taking such action, with respect to such Event of Default as it shall deem
advisable and in the best interest of the Banks.

         Section 9.6.      Right to Indemnity. Except for action expressly
required of the Agent hereunder, the Agent shall be fully justified in failing
or refusing to take any action hereunder unless it shall first be indemnified to
its satisfaction by the Banks against any and all liability and expense which
may be incurred by it by reason of taking or continuing to take any such action.

         Section 9.7.      Indemnification. The Banks hereby agree to indemnify
the Agent and the Letter of Credit Bank (to the extent not reimbursed by the
Company), ratably according to their respective Commitments, from and against
any and all liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, expenses or disbursements of any kind or nature
whatsoever which may be imposed on, incurred by or asserted against the Agent
and/or the Letter of Credit Bank in any way relating to or arising out of this
Agreement, the Notes and/or the Letter of Credit or any action taken or omitted
by the Agent and/or the Letter of Credit Bank under this Agreement, the Notes
and/or the Letter of Credit; provided, however, that no Bank shall be liable for
any portion of such liabilities, obligations, losses, damages, penalties,
actions, judgments, suits, costs, expenses or disbursements resulting from the
Agent's or the Letter of Credit Bank's gross negligence or willful misconduct.
Without limitation of the foregoing, each Bank agrees to reimburse the Agent
and/or the Letter of Credit Bank promptly upon demand for its ratable share of
any reasonable out-of-pocket expenses (including reasonable counsel fees)
incurred by the Agent and/or the Letter of Credit Bank in connection with the
administration, or enforcement of, or the preservation of any rights under, this
Agreement, the Notes and/or the Letter of Credit, to the extent that the Agent
or the Letter of Credit Bank is not reimbursed for such expenses by the Company.

         Section 9.8.      Successor Agent. The Agent may resign at any time by
giving written notice thereof to the Banks and the Company and may be removed at
any time with or without cause by the Majority Banks. Upon any such resignation
or removal, the Company shall have the right to appoint a successor Agent,
subject to confirmation by the Majority Banks. If no

                                      -41-
<PAGE>

successor Agent shall have accepted such appointment within 30 days after the
retiring Agent's giving of notice of resignation or the Majority Banks' removal
of the Agent, the Agent may, on behalf of the Banks, appoint a successor Agent
who shall be willing to accept such appointment. In any event, such successor
Agent shall be a commercial bank organized or licensed under the laws of the
United States of America or of any State thereof and shall have a combined
capital and surplus of at least $1,000,000,000. Upon the acceptance of any
appointment as Agent hereunder by a successor Agent, such successor Agent shall
thereupon succeed to and become vested with all the rights, powers, privileges
and duties of the retiring or removed Agent, and the retiring or removed Agent
shall be discharged from its duties and obligations as agent under this
Agreement. After any Agent's resignation or removal hereunder as Agent, the
provisions of this Article IX shall inure to its benefit as to any actions taken
or omitted to be taken by it while it was Agent under this Agreement.

                                    ARTICLE X

                                  MISCELLANEOUS

        Section 10.1.      Rights and Remedies. No delay or failure of the
Banks, the Letter of Credit Bank or the Agent or any one of them or of the
Company in exercising any rights, powers or privileges hereunder shall affect
such right, power or privilege, nor shall any single or partial exercise thereof
preclude any further exercise thereof, or the exercise of any other right, power
or privilege. The rights and remedies of the Banks, the Letter of Credit Bank
and the Agent or any one of them and of the Company under this Agreement are
cumulative and not exclusive of any rights or remedies which they would
otherwise have. Failure on the part of any Bank, the Letter of Credit Bank, the
Agent or the Company to exercise any right, power or privilege given it
hereunder shall not be the breach of any obligation of the Bank or the Company
to any other party to this Agreement or to any other Person.

        Section 10.2.      Notices. Except as otherwise expressly provided for
herein, notices, which may be given or are required to be given hereunder, shall

         writing to the Company and the Agent from time to time.

A party may specify a different address or facsimile number by furnishing such

of being given by mail or facsimile, be delivered personally to any officer of
any party to whose attention it could have been addressed.

        Section 10.3.      Expenses, Indemnification, Etc. (a) The Company shall
pay all reasonable costs, expenses, taxes and fees (i) incurred by the Agent in
connection with the preparation, execution and delivery of this Agreement, the
Notes and all other documents incident hereto or thereto (collectively, the
"Loan Documents") including, without limitation (but subject to the provisions
of the Fee Letter), the reasonable costs and professional fees of Chapman and
Cutler, Chicago, Illinois, whether or not any transaction contemplated hereby
shall be consummated, and any and all stamp, intangible or other taxes that may
be payable or determined in the future to be payable in connection therewith,
(ii) incurred by the Agent in connection with the preparation, execution and
delivery of any waiver, amendment or consent by the Banks, the Letter of Credit
Bank or the Agent relating to the Loan Documents including, without limitation,
reasonable costs and professional fees of counsel for the Agent; and (iii)
actually incurred by the Agent, the Letter of Credit Bank or any of the Banks in

attorneys' fees of counsel for the Agent, the Letter of Credit Bank or the
Banks.

         (b)      The Company shall indemnify the Agent, the Letter of Credit
Bank and each Bank and hold the Agent, the Letter of Credit Bank and each Bank
(and all directors, officers, employees and agents of any of the foregoing (the
Agent, the Letter of Credit Bank, the Banks and such directors, officers,
employees and agent each referred to as an "Indemnified Party")) harmless
against, any and all costs, losses, liabilities, claims, damages or expenses
incurred by an Indemnified Party, whether jointly or severally, and whether or
not such Indemnified Party is designated a party thereto, arising out of or by
reason of, or relating directly or indirectly to, (i) any investigation,
litigation or other proceeding, pending or threatened, regarding any actions or
failure to act by the Company involving this Agreement or any transaction
contemplated hereby, (ii) any actual or proposed use by the Company or any of
its Subsidiaries of the proceeds from any borrowing hereunder or the Letter of
Credit, or (iii) the Agent's, any Bank's, the Letter of Credit Bank's or the
Company's entering into and complying with this Agreement or in issuing or
delivering the Notes or the Letter of Credit and including, without limitation,
the reasonable fees and disbursements of such Indemnified Party's separate
counsel incurred in connection with any such investigation, litigation or other
proceeding (which shall be advanced by the Company on request notwithstanding
any claim or assertion that the Indemnified Party is not entitled to
indemnification hereunder upon receipt of an undertaking to reimburse the
Company if it is actually and finally determined by a court of competent
jurisdiction that the party is not so entitled). However, the indemnity of the
Company set forth herein shall not cover the costs, losses, liabilities, claims,
damages or expenses (x) incurred by an Indemnified Party arising out of the bad
faith or willful misconduct of such Indemnified Party (as actually and finally
determined by a court of competent jurisdiction) or (y) incurred by the Agent in
connection with a suit, claim or cause of action brought against the Agent by a
Bank pursuant to which such Bank alleges that the Agent has failed to perform
the ministerial duties of the Agent as expressly set forth herein (such as
administering the funding and collection of Loans, determining interest rates
and the like).

         (c)      The Agent, the Letter of Credit Bank and each Bank agree that
in the event that any investigation, litigation, suit, action or proceeding is
asserted or threatened in writing or instituted against it or any other
Indemnified Party for which the Agent, the Letter of Credit Bank or any Bank may
desire indemnity or defense hereunder, the Agent, the Letter of Credit Bank or
such Bank shall promptly notify the Company thereof in writing and agree, to the
extent appropriate, to consult with the Company with a view to minimizing the
cost to the Company of its obligations under this Section 10.3.

         (d)      No action taken by legal counsel chosen by an Indemnified
Party in defending against any such investigation, litigation, suit, action or
proceeding or requested remedial, removal or response action shall vitiate or in
any way impair the obligations and duties of the Company hereunder to indemnify
and hold harmless each Indemnified Party; provided, however, that if the Company
is required to indemnify any Indemnified Party pursuant hereto, such Indemnified
Party shall not settle or compromise any such investigation, litigation, suit,
action or proceeding without the prior written consent of the Company (which
consent shall not be unreasonably withheld or delayed) so long as the Company
has provided evidence reasonably satisfactory to such Indemnified Party that the
Equity of the Company and its Subsidiaries on a consolidated basis is not less
than zero.

                                      -44-

         (e)      The obligations of the Company under this Section 10.3 shall
survive transfer, payment or satisfaction of any Loan, Reimbursement Obligation
and Note and any amendment, supplementation, modification or termination of this
Agreement.

        Section 10.4.      Amendments to This Agreement and the Notes. Any
provisions of this Agreement and the Notes may be amended, terminated, waived or
otherwise modified in writing by the Company and the Majority Banks, and any
such amendment, termination, waiver or other modification shall be binding upon
all of the Banks to the same extent and with the same effect as if each Bank had
joined therein; provided, however, that, notwithstanding the foregoing: (a) any
provisions of this Agreement and the Notes with respect to any change in (i) the
expressed maturity date of the whole or any portion of principal or interest
payable hereunder or on any Loan or under any Note, (ii) the rate of interest
payable on any Loan or on the Reimbursement Obligations, (iii) the amount of any
Commitment (except as permitted in Sections 2.17 and 10.6), (iv) the amount or
due date of any fees payable hereunder, or (v) the due date of any principal of,
or interest on, any Loan, or the date on which any Reimbursement Obligation is
due and payable, or (vi) this Section 10.4, may be amended or otherwise modified
only in a writing signed by the Company and all of the Banks; (b) any Event of
Default described in Sections 7.1(a), 7.1(b) or 7.1(c) may be waived only in a
writing signed by all of the Banks; (c) no provisions of Article IX shall be
amended, modified, or waived without the consent of the Agent and Letter of
Credit Bank; and (d) no provisions of Sections 2.1, 2.2, 2.3, 2.4, 2.5, 2.6, 2.7
or 2.8 shall be amended, modified or waived without the consent of the Letter of
Credit Bank. The definition of "Majority Banks" as set forth herein shall not be
changed without the unanimous consent of the Banks.

        Section 10.5.      Agreement as to Right of Set-off, Sharing of Losses.
So long as any Loan or Reimbursement Obligation is outstanding, each Bank agrees
that, if it has received payment on any Loan or Reimbursement Obligation,
whether by set-off or otherwise, including, but not limited to, any payment
received by such Bank under any applicable bankruptcy, insolvency or similar
laws, in a greater proportion than payments made on all such Obligations then
outstanding to the Banks, the Bank so receiving such greater proportionate
payment agrees to purchase a portion of the Loans or Reimbursement Obligations
or participations therein held by the other Banks, so that after such purchase
each Bank will hold an unpaid balance on its Loans or Reimbursement Obligations
or participations therein bearing the same proportion to the then outstanding
aggregate principal amount of the Loans and Reimbursement Obligations as such
Bank's Commitment bears to the Banks' aggregate Commitments; provided that if
any amount so received by any Bank in payment of the Loans or Reimbursement
Obligations or participations therein held by it shall be, as a result of the
reversal of the exercise of any such right (whether by court order or voluntary
action on the part of such Bank), returned to the Company or other Subsidiary or
paid as directed by such court order by such Bank, then each other Bank which
shall have theretofore received its share of any such payment pursuant to this
Section 10.5 shall, upon demand, promptly repay, without interest, the amount of
such share to such Bank, or, if the Bank exercising such right shall not have
made the purchases provided for in this Section 10.5 prior to such reversal, the
other Banks shall have no further rights under this Section 10.5 in respect to
such amount. Except as provided in this Section and in Sections 9.6 and 9.7, no
Bank shall be responsible to any other Bank for losses or claims which such Bank
may incur in connection with the transactions contemplated by this Agreement.
The Company

                                      -45-
<PAGE>

agrees that any Bank so purchasing a participation from another Bank pursuant to
this Section 10.5 may exercise all its rights of payment (including the right of
set-off) with respect to such participation as fully as if such Bank were the
direct creditor of the Company in the amount of such participation.

        Section 10.6.      Successors and Assigns; Participations. (a) This
Agreement shall be binding upon the Company, the Agent, the Letter of Credit
Bank and the Banks and their respective successors and assigns, and shall inure
to the benefit of the Company and the Banks and their respective successors and
assigns. The Company may not assign its rights or obligations hereunder, except
as permitted by Section 6.3 hereof. Other than by virtue of operation of law, no
Bank shall assign any portion of its Commitment hereunder unless (a) if the
assignee is not a Bank hereunder nor an affiliate of such assigning Bank, the
portion of the Bank's Commitment to be assigned is equal to or greater than
$5,000,000 (or such lesser amount as the Company may approve in its sole
discretion), (b) the assigning Bank has received the prior written approval of
the Company, the Agent and the Letter of Credit Bank to the proposed assignment
(which consents of the Company and the Agent shall not be unreasonably
withheld); (c) the Agent has been paid an assignment fee of $3,500 by the
assigning Bank; and (d) the bank which has received the assignment of the
Commitment, the assigning Bank, the Company and the Agent shall have executed an
Assumption Agreement substantially in the form of Exhibit C hereto. Upon
compliance with the provisions set forth above, such financial institution shall
thereupon and thereafter be deemed to be a Bank for all purposes hereunder, and
the Agent shall give notice to all of the Banks of the assignment.

         (b)      Any Bank may at any time grant to one or more banks or other
institutions (each a "Participant") participating interests in its Commitment or
any or all of its Loans or Reimbursement Obligations. In the event of any such
grant by a Bank of a participating interest to a Participant, whether or not
upon notice to the Company and the Agent, such Bank shall remain responsible for
the performance of its obligations hereunder, and the Company and the Agent
shall continue to deal solely and directly with such Bank in connection with
such Bank's rights and obligations under this Agreement. Any agreement pursuant
to which any Bank may grant such a participating interest shall provide that
such Bank shall retain the sole right and responsibility to enforce the
obligations of the Company hereunder including, without limitation, the right to
approve any amendment, modification or waiver of any provision of this
Agreement; provided that such participation agreement may provide that such Bank
will not agree to any modification, amendment or waiver of this Agreement
described in clause (i), (ii), (iv) or (v) of Section 10.4 without the consent
of the Participant. The Company agrees that each Participant shall, to the
extent provided in its participation agreement, be entitled to the benefits of
Article VIII with respect to its participating interest; provided that no
Participant shall be entitled to receive any greater payment thereunder than the
Bank which granted it a participating interest would be entitled to receive. An
assignment or other transfer which is not permitted by subsection (a) above or
(c) below shall be given effect for purposes of this Agreement only to the
extent of a participating interest granted in accordance with this subsection.

         (c)      Any Bank may at any time assign all or any portion of its
rights under this Agreement and its Notes to a Federal Reserve Bank. No such
assignment shall release the transferor Bank from its obligations hereunder.

                                      -46-
<PAGE>

        Section 10.7.      Holidays. When any payment hereunder falls due on a
day that is not a Business Day, such payment shall be made as herein provided on
the next succeeding Business Day. Interest shall continue to accrue on the
principal to be paid until it is paid.

        Section 10.8.      Governing Law; Submission to Jurisdiction; Venue. (a)
THIS AGREEMENT AND THE RIGHTS AND OBLIGATIONS OF THE PARTIES HEREUNDER SHALL BE
CONSTRUED IN ACCORDANCE WITH AND BE GOVERNED BY THE LAW OF THE STATE OF NEW
YORK, WITHOUT REGARD TO PRINCIPLES OF CONFLICTS OF LAW.

         (b)      Any legal action or proceeding against the Company with
respect to this Agreement may be brought in any court of the State of New York
sitting in the Borough of Manhattan or in the United States District Court for
the Southern District of New York, and, by execution and delivery of this
Agreement, the Company hereby irrevocably accepts for itself and in respect of
its property, generally and unconditionally, the jurisdiction of the aforesaid
courts for such purposes.

         (c)      The Company hereby irrevocably waives any objection which it
may now or hereafter have to the laying of venue of any of the aforesaid actions
or proceedings arising out of or in connection with this Agreement brought in
the courts referred to in clause (b) above and hereby further irrevocably waives
and agrees not to plead or claim in any such court that any such action or
proceeding brought in any such court has been brought in an inconvenient forum.

        Section 10.9.      Right of Setoff. If an Event of Default shall have
occurred and be continuing, the Agent, on behalf of itself, the Letter of Credit
Bank and each Bank, is hereby authorized at any time and from time to time, to
the fullest extent permitted by law, to set off and apply any and all deposits
(general or special, time or demand, provisional or final) at any time held any
other indebtedness at any time owing by the Agent to or for the credit or the
account of the Company against any and all of the obligations of the Company
then existing under this Agreement held by the Agent. The right of the Agent
under this Section 10.9 is in addition to other rights and remedies which the
Agent, the Letter of Credit Bank or such Bank may have. Promptly following any
exercise of the right of setoff, the Agent shall give the Company written notice
thereof.

       Section 10.10.      Execution and Effective Date. This Agreement may be
executed in any number of counterparts, and any party hereto may execute this
Agreement by signing any such counterpart. The Company shall deliver one such
executed counterpart to the Agent and the Letter of Credit Bank and each Bank
shall deliver one such executed counterpart to the Agent for further delivery to
the Company. This Agreement shall be effective as of the Effective Date.

       Section 10.11.      Representations of Banks. Each Bank represents for
itself only that it is acquiring the Loans, Reimbursement Obligations and Notes
to be acquired by it hereunder for its own account in the ordinary course of
extending credit as a banking institution and not with a view to the
distribution or resale thereof, subject, nevertheless, to any requirement of law
that the disposition of the property of a Bank shall at all times be within its
control.

       Section 10.12.      Severability. Any provision of this Agreement or of
the Notes which is prohibited or unenforceable in any jurisdiction shall, as to
such jurisdiction, be ineffective to the extent of such prohibition or
unenforceability without invalidating the remaining provisions hereof or thereof
or affecting the validity or enforceability of such provisions in any other
jurisdiction.

       Section 10.13.      Entire Agreement. This Agreement and the Notes
express the entire understanding of the parties with respect to the transactions
contemplated hereby. Neither this Agreement, the Notes nor any term hereof or
thereof may be changed, waived, discharged or terminated orally or in writing,
except as provided in Section 10.4 hereof.

                   FORM OF ASSIGNMENT AND ASSUMPTION AGREEMENT

         AGREEMENT dated as of __________, ______, among _______________________
(the "Assignor"), _______________________ (the "Assignee"), DELTA AIR LINES,
INC., (the "Company") and BAYERISCHE HYPO- UND VEREINSBANK AG, NEW YORK BRANCH,
as Agent (the "Agent").

                                   WITNESSETH:

         WHEREAS, this Assignment and Assumption Agreement (the "Agreement")
relates to the Credit Agreement dated as of May 19, 2000 among the Company, the
Assignor and the other Banks party thereto, as Banks, Bayerische Hypo- und
Vereinsbank AG, New York Branch, as Letter of Credit Bank and the Agent (as
amended, modified or supplemented from time to time, the "Credit Agreement");

         WHEREAS, as provided under the Credit Agreement, the Assignor has a
Commitment to make Loans to the Company and participate in Drawings made under
the Letter of Credit in an aggregate principal amount at any time outstanding
not to exceed $______________.

         WHEREAS, Loans made to the Company by the Assignor and Reimbursement
Obligations owed to the Assignor under the Credit Agreement in the aggregate
principal amount of $__________ are outstanding at the date hereof and a
description of the interest rates and interest periods of such Loans and
Reimbursement Obligations is attached as Schedule 1 hereto; and

         WHEREAS, the Assignor proposes to assign to the Assignee all of the
rights of the Assignor under the Credit Agreement in respect of a portion of its
Commitment thereunder in an amount equal to $ __________ (the "Assigned
Amount"), together with a corresponding portion of the outstanding Loans and
Reimbursement Obligations owed to Assignor, and the Assignee proposes to accept
assignment of such rights and assume the corresponding obligations from the
Assignor on such terms;

         NOW, THEREFORE in consideration of the foregoing and the mutual
agreements contained herein, the parties hereto agree as follows:

           Section 1.     Definitions.  All capitalized terms not otherwise
defined herein shall have the respective meanings set forth in the Credit
Agreement.

           Section 2.     Assignment. The Assignor hereby assigns and sells to
the Assignee all of the rights of the Assignor under the Credit Agreement to the
extent of the Assigned Amount, and the Assignee hereby accepts such assignment
from the Assignor and assumes all of the obligations of the Assignor under the
Credit Agreement to the extent of the Assigned Amount, including the purchase
from the Assignor of the corresponding portion of the principal amount
<PAGE>

of the Loans made by the Assignor outstanding at the date hereof and
Reimbursement Obligations owed to Assignor outstanding at the date hereof. Upon
the execution and delivery hereof by the Assignor, the Assignee, the Company and
the Agent and the payment of the amounts specified in Section 3 required to be
paid on the date hereof (i) the Assignee shall, as of the date hereof, succeed
to the rights and be obligated to perform the obligations of a Bank under the
Credit Agreement with a Commitment in an amount equal to the Assigned Amount,
and (ii) the Commitment of the Assignor shall, as of the date hereof, be reduced
by a like amount and the Assignor released from its obligations under the Credit
Agreement to the extent such obligations have been assumed by the Assignee. The
assignment provided for herein shall be without recourse to the Assignor.

           Section 3.      Payments. As consideration for the assignment and
sale contemplated in Section 2 hereof, the Assignee shall pay to the Assignor on
the date hereof in Federal funds the amount heretofore agreed between them.* It
is understood that fees accrued to the date hereof with respect to the Assigned
Amount are for the account of the Assignor and such fees accruing from and
including the date hereof are for the account of the Assignee. Each of the
Assignor and the Assignee hereby agrees that if it receives any amount under the
Credit Agreement which is for the account of the other party hereto, it shall
receive the same for the account of such other party to the extent of such other
party's interest therein and shall promptly pay the same to such other party.

           Section 4.      Consent of the Company. This Agreement is conditioned
upon the consent of the Company, Agent and Letter of Credit Bank pursuant to
Section 10.6(a) of the Credit Agreement. The execution of this Agreement by the
Company, Agent and Letter of Credit Bank is evidence of this consent. Pursuant
to Section 10.6(a) the Company agrees to execute and deliver a Note payable to
the order of the Assignee to evidence the assignment and assumption provided for
herein.

           Section 5.      Non-Reliance on Assignor. The Assignor makes no
representation or warranty in connection with, and shall have no responsibility
with respect to, the solvency, financial condition, or statements of the
Company, or the validity and enforceability of the obligations of the Company in
respect of the Credit Agreement or any Note. The Assignee (i) acknowledges that
it has, independently and without reliance on the Assignor, and based on such
documents and information as it has deemed appropriate, made its own credit
analysis and decision to enter into this Agreement and will continue to be
responsible for making its own independent appraisal of the business, affairs
and financial condition of the Company and (ii) designates as its address for
notices the office set forth beneath its name on the signature page hereof.

           Section 6.    Governing Law. This Agreement shall be governed by and
construed in accordance with the laws of the State of New York.

--------
* Amount should combine principal together with accrued interest and breakage
  compensation, if any, to be paid by the Assignee, net of any portion of any
  upfront fee to be paid by the Assignor to the Assignee. It may be preferable
  in an appropriate case to specify these amounts generically or by formula
  rather than as a fixed sum.

                                      -2-

              FORM OF OPINION OF ASSOCIATE GENERAL COUNSEL OF DELTA
                                  May 19, 2000

To the Banks, the Letter of Credit Bank
   and Agent Referred to Below
c/o Bayerische Hypo- und Vereinsbank AG,
   New York Branch, as Agent
150 East 42nd Street, 30th Floor
New York, New York 10017

Ladies and Gentlemen:

         This opinion is delivered to you in connection with the Credit
Agreement dated as of May 19, 2000 (the "Credit Agreement") among Delta Air
Lines, Inc., a Delaware corporation (the "Company"), each of the financial
institutions initially a signatory thereto, together with those assignees
pursuant to Section 10.6 thereof (the "Banks"), and Bayerische Hypo- und
Vereinsbank AG, New York Branch, as Letter of Credit Bank and Agent. This
opinion is given pursuant to clause (b) of Section 3.1 of the Credit Agreement.
Capitalized terms used herein and not otherwise defined herein have the same
meaning as ascribed to them in the Credit Agreement.

         In connection with the opinions expressed below, I or counsel under my
general supervision have examined the Credit Agreement and originals or copies,
certified or otherwise identified to my satisfaction, of such other agreements,
documents, certificates and statements of government officials and other papers
as I deemed necessary or advisable as a basis for such opinions. In all such
examinations, I have assumed the genuineness of all signatures (other than those
on behalf of the Company), the legal capacity of natural persons, the
authenticity of all documents submitted to me as originals and the conformity to
original documents of all documents submitted to me as certified or photostatic
copies, and as to certificates and telegraphic and telephonic confirmations
given by public officials, I have assumed the same to have been properly given
and to be accurate. I have also assumed that all documents and instruments
executed by the parties to this transaction (other than the Company) have been
duly and validly executed and delivered by such parties; that the agreements
entered into as part of this transaction are the legal, valid and binding
obligations of such parties, enforceable against such parties in accordance with
their terms; and that such parties have obtained all required
<PAGE>

consents, permits and approvals required to enter into and perform such
documents and instruments.

         Based on the foregoing, and subject to any exceptions or qualifications
expressly noted herein, I am of the opinion that:

         1.       The Company is a corporation duly organized, existing, and in
good standing under the laws of the State of Delaware, and the execution,
delivery and performance of the Credit Agreement is within the Company's
corporate powers.

         2.       The Company has the necessary corporate power to carry on its
business as now being conducted.

         3.       The Company is an "air carrier" within the meaning of the
Federal Aviation Act of 1958, as amended, and has been duly qualified as a
foreign corporation for the transaction of business and is in good standing
under the laws of each jurisdiction in the United States of America (other than
that of its incorporation) in which it has intrastate routes or has a principal
office or major overhaul facility and where the failure to so qualify would have
a material adverse effect on the financial condition or operations of the
Company and its subsidiaries, taken as a whole.

         4.       The Company has title to all of the flight equipment which it
owns free and clear of all liens and encumbrances except as permitted by the
Credit Agreement.

         5.       To my knowledge without independent inquiry, all leases of
flight equipment to which the Company is a party are valid and binding upon the
lessors.

         6.       No consent of stockholders of the Company to the mortgages,
pledges, encumbrances, liens or other charges referred to in Section 5.6 of the
Credit Agreement is required by law or by the Certificate of Incorporation or
By-laws of the Company or otherwise.

         7.       All corporate steps necessary to authorize the execution and
delivery of the Credit Agreement and the Company's performance thereunder have
been taken, and no consent, approval, authorization, permit or license from any
federal, state or other regulatory authority is required in connection
therewith. The Credit Agreement has been duly executed and delivered by the
Company.

         8.       The borrowings pursuant to the Credit Agreement, the issuance
of the Letter of Credit for the account of the Company and the execution and
delivery of the Credit Agreement by the Company will not violate any provision
of the General Corporation Law of the State of Delaware or the Company's
Certificate of Incorporation or By-laws or any material agreement,

                                      -2-
<PAGE>

indenture, note or other instrument evidencing any indebtedness for money
borrowed to which the Company is a party or by which the Company or its assets
is bound.

         The foregoing opinions are subject to the qualification that I am
qualified to practice law in the State of Georgia and I do not purport to be an
expert on, or to express any opinion herein concerning, any laws other than the
laws of the State of Georgia, the General Corporation Laws of the State of
Delaware and the federal laws of the United States.

         The opinions expressed herein are furnished to you in connection with
the above matter, are for your sole benefit, and may not be relied upon by any
other person without my prior written consent.

                                    Sincerely,

                                      -3-

                    FORM OF OPINION OF DAVIS POLK & WARDWELL
                                  May 19, 2000

To the Banks, the Letter of Credit Bank
   and Agent Referred to Below
c/o Bayerische Hypo- undVereinsbank AG,
   New York Branch, as Agent
150 East 42nd Street, 30th Floor
New York, New York 10017

Ladies and Gentlemen:

         We have acted as counsel for Delta Air Lines, Inc., a Delaware
corporation (the "Company"), in connection with the Credit Agreement dated as of
May 19, 2000 (the "Credit Agreement"), among the Company, each of the financial
institutions initially a signatory thereto, together with those assignees
pursuant to Section 10.6 thereof (the "Banks"), and Bayerische Hypo- under
Vereinsbank AG, New York Branch, as Letter of Credit Bank and Agent. This
opinion is being rendered to you at the request of our client pursuant to clause
(b) of Section 3.1 of the Credit Agreement. Capitalized terms used herein and
not otherwise defined herein have the meanings given to them in the Credit
Agreement.

         We have examined originals or copies, certified or otherwise identified
to our satisfaction, of such documents, corporate records, certificates of
public officials and of the Company and other instruments, and have conducted
such other investigations of fact and law as we have deemed necessary for the
purposes of rendering this opinion. For purposes of this opinion, we have
assumed the authenticity of all documents submitted to us as originals, the
conformity to originals of all documents submitted to us as copies, the capacity
of all natural persons and the genuineness of all signatures.

         Based upon the foregoing, we are of the opinion that:

                  (i)      The execution, delivery and performance by the
         Company of the Credit Agreement are within the Company's corporate
         powers and the Credit Agreement has been duly executed and delivered by
         the Company pursuant to due authorization.

                  (ii)     The Credit Agreement constitutes a valid and binding
         obligation of the Company, enforceable against the Company in
         accordance with its terms, subject to bankruptcy, insolvency,
         fraudulent conveyance or similar laws affecting creditors' rights
         generally and general principles of equity (regardless of whether such
         enforceability is considered in a proceeding in equity or at law).
<PAGE>

         We express no opinion, however, as to the validity, priority or
perfection of any security interest contemplated to be created pursuant to
Section 2.19, Section 5.6 or clause (iii) of the first sentence of Section 7.1
of the Credit Agreement.

         We are members of the Bar of the State of New York and the foregoing
opinion is limited to the laws of the State of New York, the federal laws of the
United States of America and the General Corporation Law of the State of
Delaware. Insofar as the foregoing opinion involves matters governed by the laws
of the State of Georgia, we have, with your consent, relied, without independent
verification, on the opinion of Leslie P. Klemperer, Esq., Associate General
Counsel of the Company, dated the date hereof and delivered to you.

         This opinion is rendered solely to you in connection with the above
matter at the request of the Company. This opinion may not be relied upon by you
for any other purpose or relied upon by or furnished to any other person without
our prior written consent.

                                    Very truly yours,

                                      -2-

accordance with their respective terms, except as enforcement may be limited by
applicable bankruptcy, insolvency fraudulent conveyance, reorganization,
moratorium or other laws affecting the enforcement of creditors' rights
generally and by general equitable principles (whether enforcement is sought by
proceedings in equity or at law); and (d) no consent or approval, authorization,
permit or license from any federal, state or other regulatory authority which
has not been obtained is required for, and in the absence of which would
materially adversely effect, the legal and valid execution and delivery or
performance by the Company of this Amendment or the performance by the Company
of the Agreement, as amended by this Amendment, or any other Loan Document to
which it is a party.

         6.2.     This Amendment may be executed in any number of counterparts
and by the different parties on separate counterparts and each such counterpart
shall be deemed to be an original, but all such counterparts shall together
constitute but one and the same Amendment.

         6.3.     Except as specifically provided above, the Agreement and the
other Loan Documents shall remain in full force and effect and are hereby
ratified and confirmed in all respects. The execution, delivery, and
effectiveness of this Amendment shall not, except as expressly provided herein,
operate as a waiver of any right, power, or remedy of the Agent, Letter of
Credit Bank or any Bank under the Credit Agreement or any of the other Loan
Documents, nor constitute a waiver or modification of any provision of any of
the other Loan Documents.

         6.4.     All defined terms used herein and not defined herein shall
have the same meaning herein as in the Agreement or the Letter of Credit (as
defined in the Agreement).

financial condition or results of operations of the Company and its
Subsidiaries taken as a whole, and (B) will not conflict with, or result in a
breach of the terms, conditions or provisions of, or constitute a default

</TABLE>

The Agent shall determine the Applicable Fee from time to time in accordance
with the above table and notify the Borrower, the Fronting Bank and the Lenders
of such determination from time to time. In the event the S&P Rating and the
Moody's Rating correspond to different levels on the respective table resulting
in different Applicable Fee determinations, the following provisions shall
apply. In the event the S&P Rating and the Moody's Rating differ by one level,
the Applicable Fee shall be that corresponding to the higher Rating. For
example, a "BBB+" S&P Rating and a "Baa2" Moody's Rating would result in an
Applicable Fee equal to 0.625%. In the event the S&P Rating and the Moody's
Rating differ by two levels, the Applicable Fee shall be that corresponding to
that level which is in between the two applicable levels. For example, a "BBB"
S&P Rating and a "Ba1" Moody's Rating would result in an Applicable Fee equal

Moody's Rating would result in an Applicable Fee equal to 0.75%. In the event
the S&P Rating and the Moody's Rating differ by four levels (i.e. a ratings
split between level 1 and level 5), the Applicable Fee shall be that
corresponding to level 4. For example, a "BBB+" S&P Rating and a "Ba2" Moody's
Rating would result in an Applicable Fee equal to 1.25%. In the event only one
rating agency exists or continues rating the Borrower's long term senior
unsecured debt, such agency's rating shall be used for purposes of the
respective table. In the event: (i) neither agency exists or continues rating
the Borrower's long-term senior unsecured debt or (ii) the Borrower no longer
has any outstanding long term senior unsecured debt to be rated, the Applicable
Fee for the first 90 days after such occurrence shall be the Applicable Fee in
effect as determined using the above immediately prior to such occurrence.
During such 90-day period, the Agent and the Borrower shall negotiate in good
faith to agree upon a new pricing grid or other appropriate pricing terms. Any
such new grid or pricing terms shall be approved by the Fronting Bank and all
of the Lenders. In the event the Agent, the Borrower, the Fronting Bank and all
of the Lenders cannot agree upon such new pricing grid or pricing terms by the
end of such 90-day period, the

                                      -2-
<PAGE>

Applicable Fee shall be that corresponding to level 3 of the above table for

and for any day during which such Advance is outstanding, the percentage amount
set forth in the table below opposite the applicable period during which such
day occurs and under the rating category applicable to the Borrower's S&P
Rating and Moody's Rating for such day:

The Agent shall determine the Applicable Margin from time to time in accordance
with the above table and notify the Borrower, the Fronting Bank and the Lenders
of such determination from time to time. In the event the S&P Rating and the
Moody's Rating correspond to different levels on the respective table resulting
in different Applicable Margin determinations, the following provisions shall
apply. In the event the S&P Rating and the Moody's Rating differ by one level,
the Applicable Margin shall be that corresponding to the higher Rating. For
example, a "BBB+" S&P Rating and a "Baa2" Moody's Rating would result in an
Applicable Margin for an Advance that has been outstanding for 95 days and
which is then bearing interest at a

                                      -3-
<PAGE>

Eurodollar Rate equal to 1.00%. In the event the S&P Rating and the Moody's
Rating differ by two levels, the Applicable Margin shall be that corresponding
to that level which is in between the two applicable levels. For example, a
"BBB" S&P Rating and a "Ba1" Moody's Rating would result in an Applicable
Margin for an Advance that has been outstanding for 95 days and which is then
bearing interest at a Eurodollar Rate equal to 1.25%. In the event the S&P
Rating and the Moody's Rating differ by three levels, the Applicable Margin
shall be that corresponding to the level immediately below the higher of such
Ratings. For example, a "BBB+" S&P Rating and a "Ba1" Moody's Rating would
result in an Applicable Margin for an Advance that has been outstanding for 95
days and which is then bearing interest at a Eurodollar Rate equal to 1.125%.
In the event the S&P Rating and the Moody's Rating differ by four levels (i.e.

that corresponding to level 4. For example, a "BBB+" S&P Rating and a "Ba2"
Moody's Rating would result in an Applicable Margin for an Advance that has
been outstanding for 95 days and which is then bearing interest at a Eurodollar
Rate equal to 1.625%. In the event only one rating agency exists or continues
rating the Borrower's long term senior unsecured debt, such agency's rating
shall be used for purposes of the respective table. In the event: (i) neither
agency exists or continues rating the Borrower's long-term senior unsecured
debt or (ii) the Borrower no longer has any outstanding long term senior
unsecured debt to be rated, the Applicable Margin for the first 90 days after
such occurrence shall be the Applicable Margin in effect as determined using
the above immediately prior to such occurrence. During such 90-day period, the
Agent and the Borrower shall negotiate in good faith to agree upon a new
pricing grid or other appropriate pricing terms. Any such new grid or pricing
terms shall be approved by the Fronting Bank and all of the Lenders. In the
event the Agent, the Borrower, the Fronting Bank and all of the Lenders cannot
agree upon such new pricing grid or pricing terms by the end of such 90-day
period, the Applicable Margin shall be that corresponding to level 3 of the
above table for the remainder of the term of this Agreement. Any necessary

effective immediately upon any change in a Rating.

                  2.01     Issuance of Letters of Credit. Prior to the
Commitment Termination Date, the Fronting Bank hereby agrees, on the terms and
subject to the conditions hereinafter set forth and on account of the Borrower,
to issue from time to time in favor of each Applicable Bond Trustee a letter of
credit, which shall be in substantially the form of Exhibit C (as issued, each,

                  (a)      If the Fronting Bank shall make any payment pursuant
to a Drawing under any Letter of Credit, the Borrower shall, or shall cause the
Applicable Bond Trustee to, reimburse the aggregate amount of such Drawing to

Termination Date of the applicable Letter of Credit, (ii) the remarketing of the
Bonds purchased with the proceeds of the related Liquidity Drawing (but only to
the extent of the proceeds of the Bonds so remarketed) and (iii) the occurrence
of a Default or Event of Default herein (such date of repayment, an "Advance
Repayment Date").

<PAGE>

                  (b)      Unless the Borrower has previously delivered written
notice to the Agent to the effect that it does not want such Liquidity Drawing
to be an Advance, a Liquidity Drawing shall constitute an Advance if on the
date of such payment the following statements shall be true: (i) the
representations and warranties contained in Sections 4.01, 4.02, 4.03, 4.05,
4.06, 4.09(a), 4.09(c), 4.10, 4.12 and 4.13 are correct on and as of the date
of such Liquidity Drawing as though made on and as of such date, except to the
extent such representations and warranties relate to an earlier date in which
case such representations and warranties shall be true and correct in all
material respects as of such earlier date and (ii) no event has occurred and is
continuing, or would result from such Advance, which constitutes an Event of
Default or a Default. Unless the Borrower shall have previously advised the
Fronting Bank in writing that one or more of the above statements is no longer
true, the Borrower shall be deemed to have represented and warranted, on the
date of each Liquidity Drawing, that the above statements are true and correct.

                  2.03     Type of Advance; Conversion; Interest Periods;
Payment of Interest; Prepayment; Breakage.

                  (a)      Each Advance shall initially be made as a Alternate
Base Rate Advance. The Borrower shall have the option to convert on any
Business Day (i) a Alternate Base Rate Advance to a Eurodollar Rate Advance and
(ii) a Eurodollar Rate Advance to a Alternate Base Rate Advance, provided that
(A) except as otherwise provided in Section 2.06, a Eurodollar Rate Advance may
be converted into a Alternate Base Rate Advance only on the last day of an
Interest Period applicable to the Eurodollar Rate Advance being converted, (B)
a Alternate Base Rate Advance may not be converted to a Eurodollar Rate Advance
unless the principal amount thereof is equal to or greater than $5,000,000, (C)
a Alternate Base Rate Advance may only be converted into a Eurodollar Rate
Advance if no Default or Event of Default is in existence on the date of the
notice of conversion or on the date of conversion and (D) no more than six (6)
Eurodollar Rate Advances shall be outstanding at any one time. Each such
conversion shall be effected by the Borrower by giving the Agent prior to 12:00
noon (New York time) at least three Business Days' prior notice (each a "Notice
of Conversion") specifying the Advances to be so converted. The Agent shall
give each Lender prompt notice of any such proposed conversion.

                  (b)      At the time it gives any Notice of Conversion in
respect of the conversion of a Alternate Base Rate Advance into a Eurodollar
Rate Advance or on the third Business Day prior to the expiration of an Interest
Period applicable to a Eurodollar Rate Advance (in the case of any subsequent
Interest Period), the Borrower shall have the right to elect, by giving the
Agent notice thereof, the interest period (each an "Interest Period") applicable
to such Eurodollar Rate Advance, which Interest Period shall, at the option of
the Borrower, be a one, two or three month period, provided that: (i) the
initial Interest Period shall commence on the date of conversion thereof and
each Interest Period occurring thereafter in respect of such Advance shall
commence on the day on which the next preceding Interest Period applicable
thereto expires; (ii) if any Interest Period relating to a Eurodollar Rate
Advance begins on a day for which there is no numerically corresponding day in
the calendar month at the end of such Interest Period, such Interest Period
shall end on the last Business Day of such calendar month; (iii) if any Interest
Period would otherwise expire on a day which is not a Business Day, such
Interest Period shall expire on the next succeeding Business Day, provided that
if any Interest Period for a Eurodollar Rate Advance would otherwise expire on a
day which is not a Business Day but is a day of

                                     -12-
<PAGE>

the month after which no further Business Day occurs in such month, such
Interest Period shall expire on the next preceding Business Day; and (iv) no
Interest Period shall extend beyond the Termination Date of the Letter of Credit
under which the Liquidity Drawing which gave rise to such Advance was made. If
upon the expiration of any Interest Period applicable to a Eurodollar Rate
Advance, the Borrower has failed to elect a new Interest Period to be applicable
to such Eurodollar Rate Advance as provided above, the Borrower shall be deemed
to have elected to convert such Eurodollar Rate Advance into a Alternate Base
Rate Advance effective as of the expiration date of such current Interest
Period.

                  (c)      The Borrower agrees to pay interest in respect of
the unpaid principal amount of each Alternate Base Rate Advance from the date
the proceeds thereof are made available to the Borrower until the date prepaid
or repaid in full at a rate per annum equal to the Alternate Base Rate in
effect from time to time plus the Applicable Margin in effect from time to
time; provided, however, that if a Default or Event of Default shall occur and
be continuing on any day on which an Alternate Base Rate Advance is outstanding
the per annum interest rate on such day shall be equal to the Alternate Base
Rate plus the Applicable Margin plus 2%.

                  (d)      The Borrower agrees to pay interest in respect of
the unpaid principal amount of each Eurodollar Rate Advance from the date the
proceeds thereof are made available to the Borrower until the date prepaid or
repaid in full at a rate per annum which shall, during each Interest Period
applicable thereto, be equal to the Eurodollar Rate for such Interest Period
plus the Applicable Margin in effect from time to time; provided, however, that
if a Default or Event of Default shall occur and be continuing on any day on
which a Eurodollar Rate Advance is outstanding the per annum interest rate on
such day shall be equal to the Eurodollar Rate for such Interest Period plus
the Applicable Margin plus 2%.

                  (e)      Accrued (and theretofore unpaid) interest shall be
payable (i) in respect of each Alternate Base Rate Advance, quarterly in
arrears on the last Business Day of each March, June, September and December,
(ii) in respect of each Eurodollar Rate Advance, on the last day of each
Interest Period applicable thereto and (iii) in respect of each Advance, (A) on
the Advance Repayment Date for such Advance, (B) on any prepayment (on the
amount prepaid), (C) upon the partial remarketing of the Bonds purchased with
the proceeds of the Liquidity Drawing which gave rise to such Advance (on the
principal amount of the Bonds so remarketed), and (D) after the Advance
Repayment Date for such Advance, on demand.

                  (f)      On each Interest Determination Date, the Agent shall
determine the interest rate for the Eurodollar Rate Advance for which such
determination is being made and shall promptly notify the Borrower and the
Lenders thereof. Each such determination shall, absent manifest error, be
conclusive and binding on all parties hereto.

                  (g)      All computations of interest shall be made on the
basis of a year of 360 days for the actual number of days (including the first
day but excluding the last day) occurring in the period for which such interest
is payable.

                  (h)      Upon at least three (3) Business Days' written
notice to the Agent, the Borrower may prepay any Eurodollar Rate Advances,
without premium (but subject to payment of the amounts, if any, required to be
paid pursuant to Section 2.03(i)), in whole at any time or from time to

                                     -13-
<PAGE>

time in part in amounts aggregating $5,000,000 or any multiple of $1,000,000 in
excess thereof by paying the principal amount being prepaid together with
accrued interest thereon to the date of prepayment. Upon at least one Business
Day's written notice to the Agent, the Borrower may prepay any Alternate Base
Rate Advances, without premium (but subject to payment of the amounts, if any,
required to be paid pursuant to Section 2.03(i)), in whole at any time or from
time to time in part by paying the principal amount being prepaid together with
accrued interest thereon to the date of prepayment.

                  (i)      The Borrower shall compensate each Lender, upon its
written request (as reasonably determined by such Lender), for all reasonable
losses, expenses and liabilities (including, without limitation, any loss,
expense or liability incurred by reason of the liquidation or reemployment of
deposits or other funds required by such Lender to fund its Eurodollar Rate
Advances) which such Lender may sustain: (i) if for any reason a conversion
from or into Eurodollar Rate Advances does not occur on a date specified
therefor in a Notice of Conversion (whether or not withdrawn by the Borrower or
deemed rescinded pursuant to Section 2.06(b)); (ii) if any prepayment or
repayment or conversion of any of its Eurodollar Rate Advances occurs on a date
which is not the last day of an Interest Period with respect thereto; (iii) if
any prepayment of any of its Eurodollar Rate Advances is not made on any date
specified in a notice of prepayment given by the Borrower; or (iv) as a
consequence of (x) any other default by the Borrower to repay its Eurodollar
Rate Advances when required by the terms of this Agreement or (y) any action
taken pursuant to Section 2.06(b).

                  2.04     Fees; Expenses.

                  (a)      The Borrower agrees to pay the Agent, for the
account of the Fronting Bank and the Lenders, within five (5) Business Days of
its receipt of a written invoice therefor (which invoice shall be sent to the
Borrower by the Agent as soon as practicable following the end of each calendar
quarter during which any Letter of Credit is outstanding and as soon as
practicable following the Applicable Termination Date for such Letter of
Credit), a non-refundable letter of credit fee in respect of each Letter of
Credit that was outstanding during such (or any portion of such) calendar
quarter or period ended on the Applicable Termination Date. The fee for each
Letter of Credit and for each such period shall equal the sum for each day such
Letter of Credit was outstanding of the product of (i) the Stated Amount of
such Letter of Credit for such day (determined at 5:00 p.m. (New York time) on
such day), (ii) the Applicable Fee for such day and (iii) a fraction, the
numerator of which is one and the denominator of which is three hundred sixty
(360).

                  (b)      The Borrower agrees to pay the Agent, for the
account of the Lenders, a non-refundable commitment fee. The commitment fee
shall accrue for the period from the Effective Date to but excluding the
earliest of (i) December 5, 2000, (ii) the date on which Letters of Credit have
been issued, the aggregate initial Stated Amounts of which equal the Total
Commitment and (iii) the second Business Day following the date on which the
Agent receives written notice from the Borrower terminating in whole or in part

date, the "Commitment Termination Date"). The commitment fee shall be payable in
arrears on the Commitment Termination Date; provided, however, that if the
Commitment Termination Date has not occurred by September 1, 2000, the
commitment fee accrued from and including the Effective Date to but excluding
September 1, 2000 shall be payable on September 1, 2000. The commitment fee

                                     -14-
<PAGE>

payable for each day during such period shall equal the product of (A) the
Unutilized Commitment for such day (determined at 5:00 p.m. (New York time) on

the Fronting Bank and each Lender harmless from and against any and all
liabilities with respect to or resulting from any delay or omission (other than
to the extent attributable to the Agent, the Arranger, the Fronting Bank or
such Lender) to pay such taxes.

                  (e)      The Borrower agrees to pay within fifteen (15) days
following the Borrower's receipt of a written demand therefor and an accounting
thereof (i) the reasonable out-of-pocket costs and expenses incurred by the
Agent and the Arranger in connection with the preparation, execution and
delivery of this Agreement and the other Financing Documents and the documents
and instruments referred to herein and therein and the syndication of this
Agreement and the Letters of Credit, (ii) in accordance with the Fee Letter,
the fees and disbursements of White & Case LLP, counsel to the Agent, incurred
in connection with the preparation, execution and delivery of the Financing
Documents, the Bond Documents and the other documents and instruments referred
to therein, (iii) all out-of-pocket costs and expenses of the Agent, the
Fronting Bank and each Lender (including, without limitation, the reasonable
fees and disbursements of counsel to the Agent, the Fronting Bank and the

Financing Document or any Bond Document which requires the consent of the

occurrence and during the continuance of any Event of Default.

                  2.05     Increased Costs; Reduced Rate of Return.

                  (a)      If any change in any Applicable Law or in the
interpretation thereof by any Governmental Authority, central bank or
comparable agency charged with the administration thereof shall have occurred
after the Effective Date, which shall either (i) impose, modify or make
applicable any reserve, capital, special deposit, or similar requirement
against letters of credit issued by, participations in letters of credit issued
by, assets held by, or deposits in or for the account of, the Fronting Bank or
any Lender; (ii) subject the Fronting Bank or any Lender to any tax, duty,
assessment

                                     -15-
<PAGE>

or other charge or withholding with respect to its obligation to maintain this
Agreement and/or the Letters of Credit, to pay Reimbursement Amounts, to
maintain its Commitment herein or to acquire Fronting Bank Interests (except for
changes in the rate of tax or the imposition of any tax or other charges on the
overall net income of the Fronting Bank or any Lender imposed by the
jurisdiction in which the Fronting Bank or such Lender has its principal
office); or (iii) impose on the Fronting Bank or any Lender any other condition
regarding this Agreement, the Letters of Credit, the obligation of any Lender to
pay Reimbursement Amounts and maintain its Commitment hereunder or acquire
Fronting Bank Interests, and the result of any event referred to in clause (i),
(ii) or (iii) above shall be to increase the cost to the Fronting Bank or any
Lender of issuing, funding or maintaining this Agreement, the Letters of Credit,
of funding Reimbursement Amounts or maintaining its Commitment or acquiring
Fronting Bank Interests or to reduce the Fronting Bank's or any Lender's rate of
return hereon, then promptly following receipt by the Borrower of written notice
by the Fronting Bank or any Lender acting through the Agent, the Borrower agrees
to pay the Fronting Bank or any such Lender such additional amount or amounts as
shall be sufficient to compensate the Fronting Bank or any such Lender for such
increased costs.

                  (b)      If the Fronting Bank or any Lender shall have
determined that the adoption of or any change in any Applicable Law regarding
capital adequacy or in the interpretation or application thereof or compliance
by the Fronting Bank or such Lender or any corporation controlling the Fronting
Bank or such Lender with any request or directive regarding capital adequacy
(whether or not having the force of law) from any Governmental Authority, in
each case made subsequent to the Effective Date, has the effect of reducing the
rate of return on the Fronting Bank's or such Lender's or such corporation's
capital as a consequence of its obligations hereunder and under the Letters of
Credit to a level below that which the Fronting Bank or such Lender or such
corporation could have achieved but for such adoption, change or compliance
(taking into consideration the Fronting Bank's or such Lender's or such
corporation's policies with respect to capital adequacy) by an amount deemed by
the Fronting Bank or such Lender to be material, then from time to time, after
submission by the Fronting Bank or such Lender acting through the Agent to the
Borrower of a written request therefor and reasonable substantiating
documentation, the Borrower shall promptly pay to the Fronting Bank or such
Lender such additional amount or amounts as will compensate the Fronting Bank
or such Lender for such reduction.

                  (c)      The Fronting Bank and each Lender agrees to promptly
notify the Agent, and upon receiving the same, the Agent agrees to promptly give
notice to the Borrower of any event of which it has knowledge, occurring after
the Effective Date, which will entitle the Fronting Bank or such Lender to
impose any increased costs hereunder. In determining any additional amounts
pursuant to Section 2.05(a) or (b), the Fronting Bank and each Lender will use
averaging and attribution methods which are reasonable, provided that the
Fronting Bank's or such Lender's, as the case may be, determination of
compensation owing under Section 2.05(a) or (b) shall be conclusive and binding
on all the parties hereto, provided such determinations are made reasonably and
in good faith. The Fronting Bank and each Lender, upon determining that any
additional amounts will be payable pursuant to this Section 2.05, will give
prompt written notice thereof to the Agent, which notice shall show the basis
for calculation of such additional amounts and reasonable substantiating
documentation, and the Agent shall promptly submit the same to the Borrower. Any
increased costs payable under this Section 2.05 shall

                                     -16-
<PAGE>

be due and payable in Dollars at such reasonable times and in such reasonable
manner as set forth in the certificate or certificates of the Agent delivered to
the Borrower pursuant to this Section.

                  (d)      The Fronting Bank and each Lender shall immediately
notify the Borrower of any event of which the Fronting Bank or Lender has
knowledge that will entitle it to compensation pursuant to this Section 2.05
and will exercise reasonable diligence to designate a different Eurodollar
lending office and/or take other measures which will avoid the need for such
compensation for increased costs and will not result in material costs to such
Fronting Bank or Lender, or be otherwise disadvantageous (in its sole
discretion) to such Fronting Bank or Lender.

                  2.06     Increased Costs, Illegality, etc.

                  (a)      In the event that the Fronting Bank or any Lender
shall have reasonably determined (which determination with respect to clause
(i) below, may be made only by the Agent):

                           (i)      on any Interest Determination Date that, by
         reason of any changes arising after the date of this Agreement
         affecting the interbank Eurodollar market adequate and fair means do
         not exist for ascertaining the applicable interest rate on the basis
         provided for in the definition of Eurodollar Rate; or

                           (ii)     at any time, that the Fronting Bank or such
         Lender shall incur increased costs or reductions in the amounts
         received or receivable hereunder with respect to any Eurodollar Rate
         Advance because of (x) any change since the Effective Date in any
         Applicable Law (whether or not having the force of law) (or in the
         interpretation or administration thereof and including the
         introduction of any new law or governmental rule, regulation, order or
         request), such as, for example, but not limited to, (A) a change in
         the basis of taxation of payments to the Fronting Bank or any Lender
         of the principal of or interest on any Eurodollar Rate Advance, any
         Fronting Lender Interests, any Reimbursement Amounts or any other
         amounts payable hereunder (except for changes in the rate of tax on,
         or determined by reference to, the net income or profits of the
         Fronting Bank or such Lender imposed by the jurisdiction in which its
         principal office is located) or (B) a change in official reserve
         requirements, but, in all events, excluding reserves required under
         Regulation D to the extent covered by Section 2.06(c) and/or (y) other
         circumstances affecting the Fronting Bank or such Lender or the
         interbank Eurodollar market or the position of the Fronting Bank or
         such Lender in such market; or

                           (iii)    at any time, that the making or continuance
         of any Eurodollar Rate Advance has been made (x) unlawful by any law
         or governmental rule, regulation or order, (y) impossible by
         compliance by the Fronting Bank or such Lender with any governmental
         request (whether or not having force of law) or (z) impracticable as a
         result of a contingency occurring after the date of this Agreement
         which materially and adversely affects the interbank Eurodollar
         market;

then, and in any such event, the Fronting Bank or such Lender acting through
the Agent (or the Agent, in the case of clause (i) above) shall promptly give
notice to the Borrower and, except in the case of clause (i) above, to the
Agent of such determination (which notice the Agent shall promptly transmit to
the Fronting Bank and each of the other Lenders). Thereafter (x) in the case of
clause (i) above, Eurodollar Rate Advances shall no longer be available until
such time as the Agent notifies the Borrower, the

                                     -17-
<PAGE>

Fronting Bank and the Lenders that the circumstances giving rise to such notice
by the Agent no longer exist, and any Notice of Conversion given by the Borrower
with respect to Eurodollar Rate Advances which have not yet been incurred by way
of conversion shall be deemed rescinded by the Borrower, (y) in the case of
clause (ii) above, the Borrower shall pay to the Fronting Bank or such Lender,
upon written demand therefor (which written demand shall show the basis for all
calculations), such additional amounts as shall be required to compensate the
Fronting Bank or such Lender for such increased costs or reductions in amounts
received or receivable hereunder (a written notice as to the additional amounts
owed to the Fronting Bank or such Lender, showing the basis for the calculation
thereof, submitted to the Borrower by the Fronting Bank or such Lender shall be
conclusive and binding on all the parties hereto, provided such determinations
are made reasonably and in good faith) and (z) in the case of clause (iii)
above, take one of the actions specified in Section 2.06(b) as promptly as
possible and, in any event, within the time period required by law.

                  (b)      At any time that any Eurodollar Rate Advance is
affected by the circumstances described in Section 2.06(a)(ii) or (iii), the
Borrower may (and in the case of a Eurodollar Rate Advance affected by the
circumstances described in Section 2.06(a)(iii) shall) either (i) if the
affected Eurodollar Rate Advance is then being made pursuant to a conversion,
cancel said Borrowing by giving the Agent notice by telephone of the
cancellation on the same date that the Borrower was notified by the Fronting
Bank or the Lender or the Agent pursuant to Section 2.06(a)(ii) or (iii), or
(ii) if the affected Eurodollar Rate Advance is then outstanding, upon at least
three Business Days' written notice to the Agent, convert such Eurodollar Rate
Advance into a Alternate Base Rate Advance.

                  (c)      In the event that the Fronting Bank or any Lender
shall determine (which determination shall be conclusive and binding on all the
parties hereto, provided such determination is made reasonably and in good
faith) at any time that by reason of Regulation D the Fronting Bank or any
Lender is required to maintain reserves in respect of Eurocurrency liabilities
(as defined in Regulation D) during any period that it has a Eurodollar Rate
Advance outstanding (each such period, for the Fronting Bank or any Lender, a
"Eurocurrency Reserve Period"), then the Fronting Bank or such Lender acting
through the Agent shall promptly give notice to the Borrower of such
determination (which notice the Agent shall promptly transmit to each of the
other Lenders), and the Borrower shall directly pay to the Fronting Bank or such
Lender additional interest on the unpaid principal portion of each Eurodollar
Rate Advance of the Fronting Bank or such Lender during such Eurocurrency
Reserve Period at a rate per annum which shall, during each Interest Period
applicable to such Eurodollar Rate Advance, be the amount by which (i) the
Eurodollar Rate for such Interest Period divided (and rounded upward to the next
whole multiple of 1/16 of 1%) by a percentage equal to 100% minus the then
stated maximum rate of all reserve requirements (including, without limitation,
any marginal, emergency, supplemental, special or other reserves) applicable to
any member bank of the Federal Reserve System in respect of Eurocurrency
liabilities (as defined in Regulation D) exceeds (ii) the Eurodollar Rate for
such Interest Period. Additional interest payable pursuant to the immediately
preceding sentence shall be paid by the Borrower at the time that it is
otherwise required to pay interest in respect of such Eurodollar Rate Advance
or, if later demanded by the Fronting Bank or any Lender, promptly on demand.
The Fronting Bank and each Lender agrees that if it gives notice to the Borrower
of the existence of a Eurocurrency Reserve Period, it shall promptly notify the
Borrower of any termination thereof, at which time the Borrower shall cease to
be obligated to pay additional interest to the Fronting Bank or such

                                     -18-
<PAGE>

Lender pursuant to the first sentence of this Section 2.06(c) until such time,
if any, as a subsequent Eurocurrency Reserve Period shall occur.

                  (d)      The Fronting Bank and each Lender shall immediately
notify the Borrower of any event of which the Fronting Bank or Lender has
knowledge that will entitle it to compensation pursuant to this Section 2.06
and will exercise reasonable diligence to designate a different Eurodollar
lending office and/or take other measures which will avoid the need for such
compensation for increased costs and will not result in material costs to such
Fronting Bank or Lender, or be otherwise disadvantageous (in its sole
discretion) to such Fronting Bank or Lender.

                  2.07     Manner of Payment; Late Payments.

                  (a)      All payments under this Agreement shall be made to
the Agent not later than 2:00 p.m. New York time on the date when due and shall
be made in Dollars in immediately available funds at the Payment Account.
Except as otherwise specifically provided herein, any payment received after
2:00 p.m. New York time (or such other time as may be specifically provided
herein) on a day shall be deemed made on the next succeeding day. Whenever any
payment to be made hereunder shall be stated to be due on a day which is not a
Business Day, the due date thereof shall be extended to the next succeeding
Business Day and, with respect to payments of principal, interest shall be
payable at the applicable rate during such extension.

                  (b)      All payments made by the Borrower hereunder shall be
made without setoff, counterclaim or other defense other than prior payment.
Nothing herein shall restrict any claim the Borrower may have against any party
hereto or any third party.

                  (c)      Except as otherwise provided in Section 2.03(c) or
(d), the Borrower agrees to pay interest at the Default Rate on all overdue
amounts to the Agent, the Fronting Bank, any Lender or any Transferee
(including unpaid Drawings) from and including the due date thereof to and
excluding the date when paid in full. Such interest shall be payable upon
demand.

                  2.08     Evidence of Debt. The Agent shall maintain in
accordance with customary industry practice a detailed account or accounts
evidencing the indebtedness of the Borrower resulting from each Drawing.

                  2.09     Obligations Unconditional. The payment obligations
of the Borrower under this Agreement are primary, absolute, independent,
irrevocable and unconditional, and shall be paid strictly in accordance with
the terms of this Agreement under all circumstances, including, without
limitation, the following circumstances: (a) any lack of validity or
enforceability of any Letter of Credit, any of the other Financing Documents or
any of the Bond Documents; (b) any amendment or waiver of or any consent or
departure from the terms and conditions of all or any of the Financing
Documents or any of the Bond Documents; (c) the existence of any claim,
set-off, defense or other right which the Borrower may have at any time,
whether in connection with this Agreement, the transactions contemplated herein
or in the other Financing Documents, in the Bond Documents or any unrelated
transaction against the Agent, the Fronting Bank, any Lender or any beneficiary
or transferee of any Letter of Credit or any other Person; (d) any statement or
any document presented under any Letter of Credit proving to be forged,
fraudulent, invalid, inaccurate or false in any respect; (e) payment by the
Fronting Bank under any Letter

                                     -19-
<PAGE>

of Credit against presentation of a draft or certificate which does not strictly
comply with the terms of such Letter of Credit; (f) any non-application or
misapplication by any Applicable Bond Trustee or any tender agent for any Bonds
or otherwise of the proceeds of any Drawing; or (g) the failure by Fronting Bank
to honor any Drawing or to make any payment demanded under any Letter of Credit
on the ground that the demand for such payment does not conform to the terms and
conditions of such Letter of Credit; provided that, the Borrower shall have a
claim against the Fronting Bank and the Fronting Bank shall be liable to the
Borrower, to the extent, but only to the extent, of any direct, as opposed to
consequential, damages suffered by the Borrower which were caused by (i) the
Fronting Bank's or any Lender's willful misconduct or gross negligence in
determining whether documents presented under any Letter of Credit complied with
the terms thereof or (ii) the Fronting Bank's willful failure or gross
negligence to pay under any Letter of Credit after the presentation to it by the
beneficiary thereof of a demand and certificate strictly complying with the
terms and conditions of such Letter of Credit.

                  2.10     Reduction of Commitments. Prior to the Commitment
Termination Date, the Borrower may, at any time and from time to time, upon at
least two (2) Business Days' prior notice to the Agent (which notice the Agent
shall promptly transmit to each of the Lenders), without premium or penalty,
terminate the Unutilized Commitment in whole or in part, provided that (a) any
such termination shall apply proportionately to reduce the Commitment of each
Lender and (b) after giving effect to such termination, the Total Commitment
shall equal or exceed the Total Stated Amount. At the close of business on the
Commitment Termination Date, the Unutilized Commitment shall be reduced to zero
and the Agent shall modify the Register to reflect such reductions in the
Commitment of each Lender.

                  2.11     Extension of Scheduled Expiration Date. At least 150
days prior to the scheduled expiration date of any Letter of Credit, the
Borrower may, by written notice to the Agent, request that the scheduled
expiration date for such Letter of Credit be extended for an additional one year
period commencing from the then scheduled expiration date. The Agent shall
promptly forward each such request to the Fronting Bank and the Lenders. The
Fronting Bank and the Lenders, in their sole and absolute discretion, shall
notify the Agent, which in turn shall notify the Borrower, of their decision
with respect to such request within 45 days of the date on which the Agent
received such request notice from the Borrower. The failure of the Agent to
notify the Borrower of any decision within such 45-day period shall be deemed to
be a rejection of such request and none of the Agent, the Fronting Bank or any
Lender shall incur any liability or responsibility whatsoever by reason of its
failure to notify the Borrower. If the Fronting Bank and all of the Lenders
agree to such a request, the Fronting Bank shall promptly (and, in any event no
later than the date that is 35 days prior to the then scheduled expiration date)
prepare and deliver to the Applicable Bond Trustee an amendment to (or a
restatement of) the applicable Letter of Credit, which amendment (or
restatement) shall reflect the new scheduled expiration date.

                  2.12     Change in Control. Upon the occurrence of a Change
in Control and at any time during the ninety (90) day period thereafter, the
Borrower shall, upon the written request of the Agent (at the direction of the
Majority Lenders), deposit with the Agent, in an interest bearing account, as
collateral, Dollars in an amount equal to the aggregate Stated Amount of all
Letters of Credit then outstanding and all other amounts owing under the
Financing Documents (the "Change in Control Collateral"). Upon the occurrence
of a Change in Control, and at any time during the ninety (90) day period
thereafter, the Fronting Bank may (and at the direction of the Majority Lenders
shall), but shall

                                     -20-
<PAGE>

not be obligated to (unless directed to do so by the Majority Lenders), deliver
written notice of such Change in Control to each Applicable Bond Trustee and
request the Applicable Bond Trustee for a series of Bonds to cause such Bonds to
be purchased. The Change in Control Collateral shall be applied against amounts
due to the Agent, the Fronting Bank and the Lenders resulting from any such
purchase. All Change in Control Collateral shall be held in the account with the
Agent until the earlier of (i) the 120th day after the occurrence of a Change in
Control or (ii) the expiration of all Letters of Credit and payment of all
Reimbursement Obligations and Advances in connection therewith, at which time
the remaining Change in Control Collateral and any interest accrued thereon
shall be returned to the Borrower.

                  2.13     Application of Amounts Received from Applicable Bond
Trustee or Applicable Tender Agent. In the event the Fronting Bank receives any
amount from any Applicable Bond Trustee or any Applicable Tender Agent, such
amount, as soon as reasonably possible, shall be (i) first, applied to
reimburse the Fronting Bank in respect of any unpaid Drawing, (ii) second,
applied to prepay any outstanding Advances, with Alternate Base Rate Advances
to be prepaid before Eurodollar Rate Advances, (iii) third, if Eurodollar Rate
Advances are prepaid in accordance with clause (ii) of this Section 2.13 other
than on the last day of the Interest Period applicable thereto, applied to pay
amounts required to be paid pursuant to Section 2.03(i), and (iv) fourth, paid
to the Borrower.

                  Section 3.        Conditions Precedent.

                  3.01     Agreement. This Agreement shall become effective on
the date that all of the following conditions have been satisfied or waived by
the Fronting Bank and the Lenders (such date, the "Effective Date"):

                  (a)      Agreement. The Agent shall have received
counterparts of this Agreement duly executed and delivered by the Borrower, the
Arranger, the Fronting Bank and each Lender listed on the signature pages
hereto.

                  (b)      Opinion. The Agent shall have received from the

of the Borrower, an opinion dated the Effective Date and addressed to the
Agent, the Fronting Bank and the Lenders in form and substance satisfactory to
the Agent and its counsel.

                  (c)      Corporate Proceedings. The Fronting Bank and the
Lenders shall be satisfied that all corporate proceedings of the Borrower taken
in connection with the transactions contemplated by this Agreement shall be in
form and substance reasonably satisfactory to the Fronting Bank and the
Lenders. The Fronting Bank and the Lenders acknowledge and agree that the
failure of the Borrower to provide evidence of corporate proceedings related to
the issuance of Bonds, other than Bonds to be issued on or about the Effective
Date, shall not, by itself, be considered a failure of this condition
precedent.

                  (d)      Financial Statements. The Agent shall have received
a copy of the Borrower's (i) annual report on Form 10-K for the year ended June
30, 1999, as filed with the U.S. Securities and Exchange Commission, and (ii)
quarterly report on Form 10-Q for the quarter ended March 31, 2000, as filed
with the U.S. Securities and Exchange Commission, together with a certificate
of an authorized

                                     -21-

statements included in such quarterly report were prepared in accordance with
GAAP, subject only to normal year-end audit adjustments.

                  (e)      Payment of Fees. The Borrower shall have paid to the
Persons entitled thereto all fees that are due and payable pursuant to Section
2.04 on or before the Effective Date.

                  (f)      Consents. The Fronting Bank and the Lenders shall be
reasonably satisfied that all necessary governmental and third party approvals,
if any, required to be obtained by the Borrower in connection with the
transactions contemplated by this Agreement and the other Financing Documents
and otherwise referred to herein and therein shall have been obtained and
remain in full force and effect (other than approvals required in connection
with any such transactions that will close after the Effective Date).

                  (g)      No Adverse Change. Nothing shall have occurred since
March 31, 2000 (and the Fronting Bank and the Lenders shall have become aware
of no facts or conditions not previously known) which the Fronting Bank or the
Lenders shall determine, in their reasonable good faith judgment, could have a
material adverse effect on their rights or remedies hereunder, or on the
ability of the Borrower to perform its obligations hereunder or which could
have a material adverse effect on the business, financial condition or results
of operations of the Borrower and its Subsidiaries taken as a whole.

                  (h)      No Litigation. The Fronting Bank and the Lenders
shall be reasonably satisfied that, on the Effective Date, no judgment, order,
injunction or other restraint shall have been issued or filed which restrains,
and no hearing seeking injunctive relief or other restraint is pending or has
been noticed which seeks to restrain, the Fronting Bank from issuing any Letter
of Credit or the Borrower from consummating the transactions described in the
Financing Documents.

                  (i)      No Default; Representations and Warranties. The
Fronting Bank and the Lenders shall be reasonably satisfied that on the
Effective Date: (a) there shall exist no Default or Event of Default and (b)
all representations and warranties of the Borrower contained herein shall be
true and correct in all material respects with the same effect as though such
representations and warranties had been made on and as of the Effective Date,
except to the extent such representations and warranties relate to an earlier
date, in which case such representations and warranties shall be true and
correct in all material respects as of such earlier date.

                  All agreements, certificates, legal opinions and other
documents and papers referred to in this Section 3.01, unless otherwise
specified, shall (x) be delivered to the Agent for the account of the Fronting
Bank and each Lender and, in the case of this Agreement, in sufficient
counterparts for each Lender and (y) be reasonably satisfactory in form and
substance to the Fronting Bank and the Lenders.

                  3.02     Letters of Credit. The Fronting Bank will issue each
Letter of Credit on the Date of Issuance therefor if all of the following
conditions have been satisfied or waived by the Fronting Bank and the Lenders:

                  (a)      The Agent shall have received a Notice of Issuance
executed by the Borrower.

                                     -22-
<PAGE>

                  (b)      The representations and warranties set forth in
Sections 4.01, 4.02, 4.03, 4.05, 4.06, 4.09(a), 4.09(c), 4.10, 4.12 and 4.13
hereof shall be true in all material respects on and as of the Date of Issuance
of such Letter of Credit with the same effect as though made on and as of such
date, except to the extent such representations and warranties relate to an
earlier date in which case such representations and warranties shall be true
and correct in all material respects as of such earlier date.

                  (c)      No Default or Event of Default shall have occurred
and be continuing on the Date of Issuance or shall result from the issuance of
such Letter of Credit.

                  (d)      The Agent shall have received a complete copy of all
Bond Documents and all Financing Documents relating to the Bonds to be secured
by such Letter of Credit, together with all opinions, consents, certificates
and receipts rendered and delivered in connection therewith, and the Agent and
its counsel shall be reasonably satisfied with the form and substance thereof.

The acceptance of the benefits of each Letter of Credit shall constitute a
representation and warranty by the Borrower to the Agent, the Fronting Bank and
each of the Lenders that all the conditions specified in Section 3.02 exist as
of the applicable Date of Issuance.

                  Section 4.        Representations and Warranties.

                  The Borrower represents and warrants to the Fronting Bank,
the Agent and each Lender that:

                  4.01     Organization; Powers. The Borrower is a corporation
duly organized and existing under the laws of the State of Delaware, has the
corporate power to own its property and carry on its business as being
conducted, and is duly qualified to do business as a foreign corporation and is
in good standing in every jurisdiction in which the nature of the business
conducted by it makes such qualification necessary.

                  4.02     Authorization; No Violation. The execution, delivery
and performance by the Borrower of this Agreement (i) has been duly authorized
by all necessary corporate action and does not require any consent or approval,
authorization, permit or license from any federal, state or other regulatory
authority which has not been obtained, or violate any law, regulation, order,
judgment, decree or determination having applicability to the Borrower or its
organizational documents, or result in a breach of, or constitute a default
under any existing indenture or credit agreement or any other agreement or
instrument to which the Borrower is a party or by which its properties may be
bound or affected except where the failure to have such consent or approval or
such violation, breach or default could not reasonably be expected to result in
a material adverse effect on the business, financial condition or results of
operations of the Borrower and its Subsidiaries taken as a whole, and (ii) will
not conflict with, or result in a breach of the terms, conditions or provisions
of, or constitute a default under, the Certificate of Incorporation or Bylaws
of the Borrower or of any agreement or instrument to which the Borrower is now
a party, which breach would have a material adverse effect on the business,
financial condition or results of operations of the Borrower and its
Subsidiaries taken as a whole.

                  4.03     Enforceability. This Agreement has been duly
executed and delivered by the Borrower and constitutes a legal, valid and
binding obligation of the Borrower enforceable against the

                                     -23-
<PAGE>

Borrower in accordance with its terms, except as enforcement may be limited by
applicable bankruptcy, insolvency, fraudulent conveyance, reorganization,
moratorium or other laws affecting the enforcement of creditors' rights
generally and by general equitable principles (whether enforcement is sought by
proceedings in equity or at law).

                  4.04     Financial Statements. The Borrower has furnished the
Fronting Bank and the Lenders with the following financial statements,
identified by the certificate of a principal financial officer of the Borrower:
balance sheets of the Borrower as at June 30, 1999 and March 31, 2000, and
income and reinvested earnings statements of the Borrower for the fiscal year
or fiscal quarter, as the case may be, ended on such dates, respectively,
certified, in the case of financial statements for the fiscal year ended June
30, 1999, by Arthur Andersen LLP. Such financial statements are true and
correct and have been prepared in accordance with GAAP, except, in the case of
the quarterly financial statements, the absence of complete footnotes and
subject to normal year-end audit adjustments. The balance sheets and their
accompanying notes present fairly the condition of the Borrower as of the dates
thereof, and the income and reinvested earnings statements present fairly the
results of the operations of the Borrower for the periods indicated. Except as
disclosed in the Official Statement as in effect on the Effective Date or
incorporated by reference therein, there has been no material adverse change in
the business, financial condition or results of operations of the Borrower and
its Subsidiaries taken as a whole since March 31, 2000.

                  4.05     Litigation. Except as disclosed in the Official
Statement as in effect on the Effective Date or incorporated by reference
therein, there is no action or proceeding pending or threatened against the
Borrower before any court or administrative agency which, in the reasonable
opinion of the Borrower, is likely to be determined in a manner which would
result in any material adverse change in the business, financial condition or
results of operations of the Borrower and its Subsidiaries taken as a whole,
and the Borrower is not in default with respect to any order, writ, injunction
or decree of any court or administrative agency, which would have a material
adverse effect on the Borrower and its Subsidiaries taken as a whole.

                  4.06     Business; Status as Air Carrier.

                  (a)      The Borrower is a duly certificated air carrier and
there are in force any certificates or other appropriate authority issued by
appropriate governmental authorities necessary to authorize the Borrower to
engage in intrastate, interstate, overseas and foreign air transportation of
persons, property and mail over the routes operated by the Borrower; and

                  (b)      no proceedings are pending or threatened, by or
before any public body, agency or authority, domestic or foreign, including but
not limited to proceedings to alter, amend, modify, suspend or revoke such
certificates in whole or in part, which might seriously affect adversely the
income from, title to, or possession of, any of the properties of the Borrower,
to an extent which would constitute a material adverse change in the business
or condition of the Borrower.

                  4.07     Funded Debt. The Borrower does not have outstanding
any Funded Debt except as set forth on Schedule 4.07 to this Agreement; and
there exists no default under the provisions of any instrument evidencing such
indebtedness or agreement relating thereto.

                                     -24-
<PAGE>

                  4.08     Title to Properties, Etc. The Borrower and its
Subsidiaries have good and marketable title to their respective properties and
assets, including the properties and assets reflected in the balance sheets
described in Section 4.04 hereof, subject to no mortgage, pledge, encumbrance,
lien or charge of any kind except mortgages, pledges, encumbrances, liens or
charges permitted by Section 5.04 hereof.

                  4.09     Tax Returns and Payments.

                  (a)      The Borrower has filed all federal income tax
returns which are required to be filed, and has paid all taxes as shown on said
returns and on all assessments received by it to the extent that such taxes
(other than those which the Borrower is contesting in good faith by appropriate
proceedings being diligently conducted) have become due.

                  (b)      The federal income tax liability of the Borrower has
been finally determined by the Internal Revenue Service and satisfied for all
fiscal years prior to and including the fiscal year ended June 30, 1992.

                  (c)      All other tax returns and reports of the Borrower
which are required to be filed have been duly filed, and all taxes and
government charges (other than those for which payment may be withheld without
penalty or those which the Borrower is contesting in good faith by appropriate
proceedings being diligently conducted) upon the Borrower, its assets, income or
franchises which are due and payable have been paid.

                  4.10     Use of Proceeds. No part of the proceeds under any
of the Letters of Credit will be used other than to pay the principal of and
interest on Bonds. The Borrower is not engaged, principally or as one of the
Borrower's important activities, in the business of purchasing or carrying any
"margin stock" as such term is defined in Regulation U of the Board of
Governors of the Federal Reserve System. After giving effect to each use of the
proceeds from any of the Letters of Credit, not more than 25% of the value of
the assets of the Borrower and its Subsidiaries (determined on a consolidated
basis) shall be represented by "margin stock".

                  4.11     Subsidiaries. Schedule 4.11 is a complete and
correct list of all Subsidiaries as of the date hereof, all of which are
corporations duly incorporated, in good standing and with corporate power to
transact the business presently conducted by them. Except as disclosed in
Schedule 4.11, the Borrower owns, directly or indirectly through one or more
Subsidiaries, all the shares of each of such Subsidiaries (except directors'
qualifying shares, if any), and all such shares are validly issued, fully paid
and non-assessable and are free and clear of all liens and rights of others
whatsoever.

                  4.12     ERISA. The Borrower and each Subsidiary have met
their minimum funding requirements under the ERISA with respect to all their
employee benefit plans covered by the minimum funding requirements of ERISA,
and have not incurred any material liability to the Pension Benefit Guaranty
Corporation (or any entity succeeding to any or all of said Corporation's
functions under ERISA) under ERISA in connection with any such plan.

                  4.13     Environmental Matters. The Borrower and its
Subsidiaries are in substantial compliance with all applicable federal, state
and local environmental laws, regulations and ordinances

                                     -25-
<PAGE>

governing their respective business, properties or assets with respect to
discharges into the ground and surface water, emissions into the ambient air and
generation, storage, transportation and disposal of waste materials or process
by-products, except such noncompliances as are not likely to have a material
adverse effect on the property, assets, business, operations or condition
(financial or otherwise) of the Borrower and its Subsidiaries taken as a whole.
All licenses, permits or registrations required for the business of the Borrower
and its Subsidiaries under any federal, state or local environmental laws,
regulations or ordinances have been secured, and the Borrower and each
Subsidiary are in substantial compliance therewith, except such licenses,
permits or registrations the failure to secure or to comply therewith are not
likely to have a material adverse effect on the property, assets, business,
operations or condition (financial or otherwise) of the Borrower and its
Subsidiaries taken as a whole.

                  Section 5.        Covenants.

                  The Borrower covenants and agrees with the Agent, the
Fronting Bank and each Lender that so long as this Agreement shall remain in
effect and until all the Letters of Credit have been terminated and all fees
and all other expenses or amounts payable under this Agreement by the Borrower
shall have been paid in full:

                  5.01     No Merger or Sale of Assets. The Borrower will not,
and will not permit any of its Subsidiaries to, merge or consolidate with any
corporation or sell, lease or transfer or otherwise dispose of all or
substantially all of its assets in any transaction or series of related
transactions, except that (i) any Subsidiary may merge or consolidate with the
Borrower or any one or more other Subsidiaries; (ii) any Subsidiary may sell,
lease, transfer or otherwise dispose of any of its assets to the Borrower or
another Subsidiary; (iii) any Subsidiary may sell or otherwise dispose of all
or substantially all of its assets, provided that (a) such sale or other
disposition is for a consideration which represents fair value (as determined
in good faith by the Borrower) at the time of such sale or disposition, and (b)
the assets so disposed of do not constitute all or substantially all of the
aggregate assets of the Borrower and the Subsidiaries; (iv) the Borrower may
dispose of aircraft in the ordinary course of its business, provided that such
sale or other disposition is for a consideration which represents fair value
(as determined in good faith by the Borrower) at the time of such sale or
disposition; and (v) the Borrower may merge or consolidate with another
corporation, provided that (a) the Borrower shall be the continuing or
surviving corporation, (b) a majority of the board of directors of the Borrower
for a period of six (6) months after the effective date of such merger consists
of individuals who were directors of the Borrower twelve (12) months prior to
such effective date, and (c) immediately after such merger or consolidation
there shall exist no Event of Default as defined herein.

                  5.02     Leases. The Borrower will not, and will not permit
any of its Subsidiaries to, enter into or permit to remain in effect any flight
equipment lease agreements which, as of the close of any fiscal year, cause the
Borrower's consolidated aircraft rentals for such fiscal year, as determined in
accordance with GAAP, to exceed eight percent (8%) of the Borrower's
consolidated operating revenues for such fiscal year, provided that any such
lease agreements as may be necessary in connection with interchange agreements
between the Borrower and other airline related businesses shall not be included
in such calculation.

                  5.03     Debt. The Borrower will not, and will not permit any
of its Subsidiaries to, create, incur, assume or suffer to exist, for the
Borrower and the Subsidiaries taken together, (a)

                                     -26-
<PAGE>

Current Debt in an aggregate principal amount at any one time outstanding in
excess of 100% of all accounts receivable of the Borrower and its Subsidiaries
outstanding as of the last day of the second calendar month next preceding the
month in which such calculation of Current Debt is made, all computed in
accordance with GAAP; or (b) Convertible Subordinated Debt in excess of 33.3% of
Equity; or (c) Funded Debt, Current Debt (other than Convertible Subordinated
Debt) and all Guaranty Liabilities (as defined below) in an amount at any one
time which exceeds 150% of Equity at such time. For purposes of this Section
5.03, "Guaranty Liabilities" shall mean all liabilities of the Borrower and any
Subsidiary of the Borrower as guarantor, surety, accommodation endorser or other
accommodation party on behalf of any Person where the underlying obligation of
such Person covered by, or the subject of, such guaranty or contingent
undertaking would constitute Current Debt or Funded Debt, as defined herein, if
such Person were the Borrower; provided, however, that (x) guarantees or other
contingent undertakings by the Borrower on behalf of any Subsidiary, by any
Subsidiary on behalf of any other Subsidiary, or by any Subsidiary on behalf of
the Borrower and (y) the contingent undertakings as set forth on Schedule 5.03
hereto, shall not constitute Guaranty Liabilities.

                  5.04     Liens. The Borrower will not, and will not permit
any of its Subsidiaries to, create, assume or suffer to exist any mortgage,
pledge, encumbrance, lien or charge of any kind upon any of its property or
assets, whether now owned or hereafter acquired, except: (i) mortgages,
pledges, encumbrances, liens or charges where the aggregate indebtedness
secured by such mortgages, pledges, encumbrances, liens or charges at any time
does not exceed the sum of (a) the greater of $3,000,000,000 or fifteen percent
(15%) of Equity plus (b) the amount outstanding under the obligations described
on Schedule 4.07 hereof as "Secured"; (ii) liens for taxes not yet due or which
are being contested in good faith; (iii) other liens, charges and encumbrances
incidental to the conduct of its business or the ownership of its property and
assets which were not incurred to secure the repayment of borrowed money or
other advances or credit, and which do not in the aggregate materially detract
from the value of its property or assets or materially impair the use thereof
in the operation of its business; (iv) liens imposed by law, such as carriers',
warehousemen's, mechanics', materialmen's and vendors' liens, for sums not yet
due or already due but the validity of which is being contested in good faith;
(v) mortgages, pledges, encumbrances, liens or other charges on property or
assets of a Subsidiary to secure obligations of such Subsidiary to the Borrower
or another Subsidiary; (vi) any mortgage, pledge, encumbrance, lien or other
charge, required by Section 5.10 hereof; (vii) any mortgage, pledge,
encumbrance, lien or other charge existing at the date hereof on any property
owned or leased by the Borrower or any Subsidiary at that date securing
obligations outstanding on that date; (viii) any mortgage, pledge, encumbrance,
lien or other charge on any property, shares of stock or obligation existing at
the time of acquisition thereof (including acquisition through merger or
consolidation) or (ix) any mortgage, pledge, encumbrance, lien or other charge
on aircraft or aircraft engines (but no other assets) now owned or acquired by
Borrower or any Subsidiary after the date hereof to secure the payment of all
or any part of the purchase price thereof or to secure any obligation incurred
or for which a firm commitment is obtained prior to, at the time of, or after,
the acquisition of such property for the purpose of financing all or any part
of the purchase price thereof.

                  5.05     Insurance. The Borrower will, and will cause each of
its Airline Subsidiaries to, keep adequately insured, by financially sound and
reputable insurers, all property of the character usually insured by
corporations engaged in the same or similar businesses similarly situated,
against loss or damage of the kind customarily insured against by such
corporations, and carry adequate liability

                                     -27-
<PAGE>

insurance and other insurance of a kind generally carried by corporations
engaged in the same or similar businesses similarly situated; provided, however,
that nothing herein contained shall be construed to mean that a deductibility
clause in any such insurance, which, in effect, results in self-insurance of a
level or portion of losses considered reasonable by the Borrower's management,
shall render such insurance inadequate; and provided, further, that in the case
of a lease to the United States Government or an agency thereof of any aircraft
or other property, indemnity therefrom by the United States Government will be
considered adequate insurance against the risks that are the subject of any such
indemnity.

                  5.06     Payment of Taxes. The Borrower will, and will cause
each of its Airline Subsidiaries to, duly file all federal income tax returns
and all other tax returns and reports which, to the knowledge of the officers
of the Borrower are required to be filed and pay when due all taxes and
governmental charges assessed against it, its assets, income or franchises,
except to the extent and so long as contested in good faith.

                  5.07     Financial Statements. The Borrower will deliver to
the Agent, the Fronting Bank and the Lenders:

the period from the beginning of the current fiscal year to the end of such
quarterly period, and a balance sheet of the Borrower as at the end of such
quarterly period, setting forth in each case in comparative form figures for
the corresponding period in the preceding fiscal year, all in reasonable detail
and certified by a principal financial officer of the Borrower, subject to
changes resulting from year-end adjustments; and a statement as of the end of
such quarterly period of the calculations made by the Borrower establishing its
compliance with the provisions of Sections 5.02, 5.03 and 5.04 hereof, in
sufficient detail to permit the Agent, Fronting Bank and the Lenders to
determine how the conclusions on such statement were arrived at, certified by
an authorized financial officer of the Borrower as accurate in all material
respects;

                  (b)      As soon as practicable and in any event within three
(3) months after the end of each fiscal year, an income statement and a

comparative form corresponding figures from the preceding annual audit, all in
reasonable detail and satisfactory in scope to the Banks and certified by
independent certified public accountants of national standing selected by the
Borrower; and a statement as of the end of such fiscal year of the calculations
made by the Borrower establishing compliance with the provisions of Sections
5.02, 5.03 and 5.04 in sufficient detail to permit the Agent, Fronting Bank and
the Lenders to determine how the conclusions on such statement were arrived at,
certified by an authorized financial officer of the Borrower as accurate in all
material respects;

                  (c)      Copies of all financial statements, reports and
returns which it shall send to its stockholders;

                  (d)      Promptly after the sending or filing thereof, copies
of all periodic reports, if any, which the Borrower shall have filed with the
Securities and Exchange Commission (or any governmental

                                     -28-
<PAGE>

agency or agencies substituted therefor) under ss.13 or ss.15(d) of the
Securities Exchange Act of 1934, as amended, or with any national securities
exchange; and

                  (e)      With reasonable promptness such other financial data
as the Fronting Bank and any Lender may reasonably request through the Agent.

                  5.08     Maintenance of Equipment. The Borrower will, and
will cause each of its Airline Subsidiaries to, maintain substantially all of
its equipment (except surplus or obsolete equipment) in good operating order.

                  5.09     Inspection. The Borrower will permit any Person
designated by any the Fronting Bank or any Lender in writing, to visit and
inspect any of the properties, corporate books and financial records of the
Borrower and its Subsidiaries at the Fronting Bank's or such Lender's expense,
and to discuss the affairs, finances, and accounts of any such corporation with
the principal officers of the Borrower, all at such reasonable times and as
often as the Fronting Bank or such Lenders may reasonably request. This covenant
shall be subject to applicable governmental and industrial security regulations.

                  5.10     Security. In the event the Borrower secures by
mortgage, pledge, encumbrance, lien or other charge any debt other than as
permitted by Section 5.04 hereof, the Borrower shall secure equally and ratably
the indebtedness incurred hereunder.

                  5.11     Notice of Any Default or Event of Default. As soon
as practicable (but in any event not more than five (5) days after the Chairman
of the Board, the President, or a principal financial officer of the Borrower
obtains knowledge of a Default or an Event of Default as specified in Section 6
hereof), the Borrower will deliver to the Agent, the Fronting Bank and each
Lender an Officer's Certificate specifying the nature thereof, the period of
existence thereof and what action the Borrower has taken or proposes to take
with respect thereto.

                  5.12     ERISA Reporting Requirements. With respect to any
employee benefit plan subject to Title IV of ERISA, the Borrower shall, if
requested by the Agent, provide the Agent with copies of the most recent annual
reports or returns (IRS Form 5500), audited or unaudited financial statements
and actuarial valuations with respect to such plans. In addition, the Borrower
shall provide the Agent copies of any notice filed with the Pension Benefit

<PAGE>

                  (a)      any representation or warranty made by the Borrower

any Lender to the Borrower;

                  (e)      the Borrower shall institute a voluntary case
seeking liquidation or reorganization under Chapter 7 or Chapter 11,
respectively, of the United States Bankruptcy Code, or shall consent to the
institution of an involuntary case thereunder against it, or the Borrower shall

worth of the Borrower.

                  6.02     Remedies.

                  (a)      Upon the occurrence of an Event of Default (other
than an Event of Default with respect to the Borrower described in Section
6.01(e)), the Agent may, and upon the written request of the Fronting Bank and
the Majority Lenders shall, by written notice to the Borrower, declare an
amount equal to the then current aggregate Stated Amount of all Letters of
Credit plus all other amounts owing to the Agent, the Fronting Bank and the
Lenders hereunder to be immediately due and payable, whereupon the same shall
become due and payable to the Agent without presentment, demand, protest or
other notice of any kind, all of which are hereby waived by the Borrower. Upon
receipt of any such written notice, the Borrower agrees to deposit with the
Agent, in an interest bearing account, as collateral, Dollars in an amount
equal to the aggregate Stated Amount of all Letters of Credit then outstanding
and all other amounts owing under the Financing Documents (the "Collateral").
The Collateral shall be applied against amounts due to the Agent, the Fronting
Bank and the Lenders and any remaining Collateral shall be held in the account
with the Agent until the earlier of (i) all Events of Default having been cured
or (ii) the expiration of all Letters of Credit and payment of all
Reimbursement Obligations and Advances in connection therewith, at which time
the remaining Collateral and any interest accrued thereon shall be returned to
the Borrower.

                  (b)      Notwithstanding the notice provisions contained in
Section 6.02(a), if an Event of Default described in Section 6.01(e) shall
occur, the results which would occur upon the giving of written notice by the
Agent to the Borrower as specified in Section 6.02(a) shall occur automatically
without the giving of any such notice.

                  (c)      Upon the occurrence of an Event of Default, the
Fronting Bank may (and, upon the direction of the Majority Lenders, shall), but
shall not be obligated to (unless so directed by the

                                     -31-
<PAGE>

Majority Lenders), deliver written notice of such Event of Default to each
Applicable Bond Trustee and request the Applicable Bond Trustee for a series of
Bonds to cause such Bonds to be purchased.

                  (d)      The Agent, the Fronting Bank or any Lender may take
such other action and exercise such other rights as are provided under
Applicable Law.

                  Section 7.        Intercreditor Arrangements. The provisions
of this Section 7 are for the sole and exclusive benefit of the Agent, the
Fronting Bank and the Lenders and the Borrower shall have no rights or
obligations under this Section 7.

                  7.01     Fronting Bank Interests.

                  (a)      In the event that the Fronting Bank honors payment
of a drawing made under the Letters of Credit and is not reimbursed therefor as
provided in Section 2.02, the Fronting Bank shall be deemed to have acquired for
its own account an undivided 100% interest in the Reimbursement Obligations
created thereby (the Fronting Bank's interests therein, the "Fronting Bank
Interests"). In the event that the Fronting Bank acquires any Fronting Bank
Interests, it shall promptly advise each Lender, if any, thereof by telephone
(promptly confirmed in writing) or by written notice, and each Lender severally
agrees to unconditionally and irrevocably buy from the Fronting Bank, and the
Fronting Bank agrees to sell to each Lender, a portion of the Fronting Bank
Interests for an amount (each such amount, a "Reimbursement Amount") equal to
such Lender's Percentage of the aggregate amount of such Fronting Bank
Interests; provided, however, that no Lender shall be required to purchase any
portion of any Fronting Bank Interest if as a result thereof the amount such
Lender would be required to pay for such purchase, when added to the amounts
paid for prior purchases of portions of Fronting Bank Interests which have not
been reimbursed by the Agent under Section 7.02, would result in such Lender
paying any amount in excess of its Commitment. The purchase price of each
portion of a Fronting Bank Interest purchased pursuant to the preceding sentence
shall be paid (without set-off, counterclaim or deduction of any kind
whatsoever) to the Fronting Bank in the manner set forth below in subsection (b)
of this Section 7.01. The Fronting Bank shall determine the amount of each
Reimbursement Amount associated with any sale of its Fronting Bank Interests,
and each such determination shall be conclusive and binding on its Lenders
absent manifest error.

                  (b)      Each Lender shall pay its Reimbursement Amount
associated with any purchase of a portion of the Fronting Bank Interests by
transferring such amount to the order of the Fronting Bank in immediately
available funds, (i) at or before 2:30 p.m. New York time on the same Business
Day, if telephonic notice confirmed by written notice (by facsimile) from the
Fronting Bank is received no later than 12:30 p.m. New York time on any
Business Day or (ii) at or before 12:00 noon New York time on the Business Day
next following the date on which notice is received, if telephonic notice
confirmed by written notice (by facsimile) from the Fronting Bank is received
later than 12:30 p.m. New York time on any Business Day. Telephonic notice
shall be deemed given to a Lender when actually given to any individual who
identifies himself or herself as an officer at such Lender's office at the
address set forth in Section 9.03 hereof. Facsimile written notice required to
be given pursuant to this Section shall be sent to the facsimile number
provided to the Fronting Bank for such purpose by each Lender. If a Lender
fails to pay to the Fronting Bank any Reimbursement Amount when due, such
Lender agrees that the Fronting Bank shall be entitled to receive, and such
Lender shall pay to the order of the Fronting Bank, interest on such amount at
a rate equal to the Alternate Base Rate in effect on

                                     -32-

each date plus 1% per annum from the date when due until paid. No Lender shall
be entitled to purchase a portion of any Fronting Bank Interests until such time
as it shall have paid all of its outstanding Reimbursement Amounts and any
interest which may be due thereon to the Fronting Bank. Each Lender further
agrees that, until it shall have paid all amounts owing to the Fronting Bank
pursuant to this Section 7.01, it shall not be entitled to receive any payment
described in clauses (i) or (ii) of subsection (b) of Section 7.02 and shall not
be permitted to vote on any matter where its consent or approval is required.

                  (c)      Each Lender's payment obligations to the Fronting
Bank under this Agreement are primary, absolute, independent, irrevocable and
unconditional, and shall be paid strictly in accordance with the terms of this
Agreement under all circumstances, including, without limitation, the following
circumstances: (i) any lack of validity or enforceability of any Letter of
Credit, any of the other Financing Documents or any of the Bond Documents; (ii)
any amendment or waiver of or any consent or departure from the terms and
conditions of all or any of the Financing Documents or any of the Bond
Documents; (iii) the existence of any claim, set-off, defense or other right
which such Lender may have at any time, whether in connection with this
Agreement, the transactions contemplated herein or in the other Financing
Documents, in the Bond Documents or any unrelated transaction against the Agent,
the Fronting Bank, any other Lender or any beneficiary or transferee of any
Letter of Credit or any person; (iv) any statement or any document presented
under any Letter of Credit proving to be forged, fraudulent, invalid, inaccurate
or false in any respect; (v) payment by the Fronting Bank under any Letter of
Credit against presentation of a draft or certificate which does not strictly
comply with the terms of such Letter of Credit; (vi) any non-application or
misapplication by any Applicable Bond Trustee or any tender agent for any Bonds
or otherwise of the proceeds of any Drawing; (vii) the failure by Fronting Bank
to honor any Drawing or to make any payment demanded under any Letter of Credit
on the ground that the demand for such payment does not conform to the terms and
conditions of such Letter of Credit; (viii) any participation or assignment by
the Fronting Bank of any interests or obligations of the Fronting Bank's under
this Agreement to any other Lender or person; (ix) any extension, indulgence,
settlement or compromise granted or agreed to in relation to this Agreement or
any other Financing Document; (x) any default by or insolvency or bankruptcy of
the Borrower; (xi) any act or omission on the part of the Agent or the Fronting
Bank relating to this Agreement or any other Financing Document; or (xii) the
absence of notice of any of the foregoing, provided that a Lender shall have a
claim against the Fronting Bank and the Fronting Bank shall be liable to a
Lender, to the extent, but only to the extent, of any direct, as opposed to
consequential, damages suffered by such Lender as a direct result of (i) the
Fronting Bank's willful misconduct or gross negligence in determining whether
documents presented under any Letter of Credit complied with the terms thereof
or (ii) the Fronting Bank's willful failure or gross negligence to pay under any
Letter of Credit after the presentation to it by the beneficiary thereof of a
demand and certificate strictly complying with the terms and conditions of such
Letter of Credit. Each Lender hereby waives presentment, protest, notice of
nonpayment of any amounts owing under this Agreement, and any defenses in law or
equity which it may have to the full discharge of any of its obligations to the
Fronting Bank under this Section 7.

                  (d)      It is understood that no Lender shall be responsible
for any default by any other Lender of its obligation to purchase portions of
Fronting Bank Interests pursuant to this Section 7 and that each Lender shall
be obligated to purchase portions of Fronting Bank Interests pursuant to this

                                     -33-
<PAGE>

Section 7 regardless of the failure of any other Lender to purchase portions of
the Fronting Bank Interests pursuant to this Section 7.

                  7.02     Payments.

                  (a)      The Fronting Bank shall be entitled to receive its
pro rata share of all payments in respect of Fronting Bank Interests which pro
rata share shall be determined by multiplying the amount of any such payment in
respect of such Fronting Bank Interests by a fraction the numerator of which is
the aggregate amount of such Fronting Bank Interests minus the aggregate amount
of the Lenders' Reimbursement Amounts and the denominator of which is the
aggregate amount of such Fronting Bank Interests (the "Fronting Bank Share") and
each Lender shall be entitled to receive its pro rata share of all payments in
respect of such Fronting Bank Interests, which pro rata share shall be
determined by multiplying the amount of any such payment in respect of such
Fronting Bank Interests by a fraction the numerator of which is the amount of
such Lender's Reimbursement Amount paid for such Fronting Bank Interest and the
denominator of which is the aggregate amount of such Fronting Bank Interests. To
the extent that any Lender fails to purchase any portion of any Fronting Bank
Interests, the Fronting Bank shall be deemed the owner of such portion.

                  (b)      The Agent shall act as paying agent on behalf of the
Fronting Bank and the Lenders with respect to any moneys received pursuant to
subsection (a) of this Section 7.02 and any other provision of this Agreement,
and the Agent shall transfer to the Fronting Bank or Lenders, as the case may
be, in accordance with the payment instructions delivered in writing by the
Fronting Bank and each Lender to the Agent the following amounts when (and if)
the Agent receives them and in the same type of funds in which the Agent
receives them: (i) the Fronting Bank's and, so long as such Lender is not in
default in any part of its obligations to the Fronting Bank pursuant to this
Section 7, such Lender's proportionate share (determined as set forth in
subsection (a) of this Section 7.02) of all payments in respect of
Reimbursement Obligations; (ii) so long as such Lender is not in default in any
part of its obligations to the Fronting Bank pursuant to this Section 7, such
Lender's pro rata share (based on its Percentage) of each commission fee and
unutilized commitment fee, if any, paid by the Borrower to the Agent pursuant
to Section 2.04 of this Agreement (if any Lender is in default of its
obligations to the Fronting Bank, the Fronting Bank shall retain the defaulting
Lender's pro rata share of such fees for its own account for each day during
which such default continues); (iii) to the Fronting Bank, each commission fee
and unutilized commitment fee, if any, paid by the Borrower to the Agent
pursuant to Section 2.04 of this Agreement net of amounts paid or to be paid to
the Lenders in respect of commitment fees pursuant to clause (ii) immediately
above; (iv) the Fronting Bank's drawing fee, if any, paid by the Borrower to
the Agent pursuant to Section 2.04 of this Agreement; (v) payments, if any,
received by the Agent on behalf of the Fronting Bank or any Lender in respect
of stamp taxes, transfer taxes, documentary taxes, expense reimbursements,
increased costs and default interest duly payable to the Fronting Bank or any
Lender pursuant to Sections 2.03(i), 2.04, 2.05 and 2.06, respectively, of this
Agreement; and (vi) payments, if any, received by the Agent on behalf of the
Fronting Bank or any Lender pursuant to Section 9.01. Funds received by the
Agent on behalf of the Fronting Bank

                                     -34-
<PAGE>

or any Lender under this Section shall, if received by the Agent prior to 10:00
a.m. New York time on any Business Day, be paid to the Fronting Bank or such
Lender no later than the Agent's close of business in New York on the same
Business Day. Funds received by the Agent on behalf of the Fronting Bank or any
Lender after 10:00 a.m. New York time on any Business Day shall be paid to the
Fronting Bank or such Lender no later than 2:00 p.m. New York time on the next
Business Day.

                  (c)      If (i) the Agent shall pay any amount to the
Fronting Bank or any Lender pursuant hereto in the belief or expectation that a
related payment has been or will be received or collected in connection with the
Fronting Bank's or any Lender's, as the case may be, interests in Fronting Bank
Interests and (ii) such related payment is not received or collected by the
Agent, then the Fronting Bank or such Lender, as the case may be, will promptly
on demand by the Agent return such amount to the Agent, together with interest
thereon at such rate as the Agent shall determine to be customary between banks
for correction of errors. If the Agent determines at any time that any amount
received or collected by the Agent in respect of any Reimbursement Obligations,
or any other amounts paid pursuant to this Agreement must be returned to the
Borrower, or paid to any other Person pursuant to any insolvency law, any
sharing clause, or otherwise, then, notwithstanding any other provision of this
Agreement, the Agent shall not be required to distribute any portion thereof to
the Fronting Bank or any Lender, and the Fronting Bank each Lender, as the case
may be, agrees to promptly on demand by the Agent repay any portion thereof that
the Agent shall have distributed to the Fronting Bank or such Lender, together
with interest thereon at such rate, if any, as the Agent shall pay to the
Borrower, or such other Person with respect thereto.

                  (d)      Except as otherwise provided in this Agreement, no
Lender shall have any right to receive any other amounts received by the Agent
or the Fronting Bank or the Arranger under this Agreement (including any
drawing fee or any payments made by the Borrower in respect of any indemnities
or expense reimbursements incurred by the Agent or the Fronting Bank pursuant
to Section 9.01) or under any other Financing Document. Any amounts other than
amounts referred to in this Section 7 received by the Agent, the Arranger or
the Fronting Bank from the Borrower pursuant to this Agreement or any other
Financing Document shall be the Agent's, the Arranger's or the Fronting Bank's,
as the case may be, sole property and shall be retained by the Agent, the
Arranger or the Fronting Bank, as the case may be, for its own account and no
Lender shall have any rights with respect to such amounts; provided, however,
that if each Lender has paid its pro rata share (based on its Percentage) of
any amounts described in Section 8.06 of this Agreement, and the Agent is
thereafter reimbursed therefor by the Borrower or otherwise, then each Lender
which makes any payment to the Agent pursuant to Section 8.06 will be entitled
to receive its pro rata share (based on its proportionate share of the advances
made to the Agent under Section 8.06) of such reimbursement.

                  7.03     Adjustment of Commitments. Each Lender's Commitment
shall be reduced concurrently with any reduction of the Stated Amount of any
Letter of Credit by its Percentage of such reduction.

                  7.04     Notices to the Lenders. Upon receipt by the Agent of
any notice under this Agreement, the Agent shall promptly forward copies of any
such notice to the Fronting Bank and each Lender.

                  Section 8.        The Agent. Except for the rights of the
Borrower set forth in Section 8.08, the provisions of this Section 8 are for
the sole and exclusive benefit of the Agent, the Fronting Bank and the Lenders
and the Borrower shall have no rights or obligations under this Section 8.

                  8.01     Appointment. The Fronting Bank and the Lenders
hereby designate Commerzbank as Agent to act as specified herein and in the
other Financing Documents. Each Lender hereby irrevocably authorizes the Agent
to take such action on its behalf under the provisions of this Agreement, the
other Financing Documents and any other instruments and agreements referred to
herein or therein and to exercise such powers and to perform such duties
hereunder and thereunder as are specifically delegated to or required of the
Agent by the terms hereof and thereof and such other powers as are reasonably
incidental thereto. The Agent may perform any of its duties hereunder by or
through its officers, directors, agents or employees.

                  8.02     Nature of Duties. The Agent shall have no duties or
responsibilities to the Arranger, the Fronting Bank or the Lenders except those
expressly set forth in this Agreement and the Financing Documents. Except as
provided in Section 9.01, neither the Agent nor any of its respective officers,
directors, agents or employees shall be liable to the Arranger, the Fronting
Bank or any Lender for any action taken or omitted by it or them hereunder or
under any other Financing Document or in connection herewith or therewith,
unless caused by its or their gross negligence or willful misconduct. The duties
of the Agent shall be mechanical and administrative in nature; the Agent shall
not have by reason of this Agreement or any other Financing Document a fiduciary
relationship in respect of the Arranger, the Fronting Bank or any Lender; and
nothing in this Agreement or any other Financing Document, expressed or implied,
is intended to or shall be so construed as to impose upon the Agent any
obligations in respect of this Agreement or any other Financing Document except
as expressly set forth herein.

                  8.03     Lack of Reliance on Agent. Independently and without
reliance upon the Agent or the Arranger, the Fronting Bank and each Lender, to
the extent it deems appropriate, has made and shall continue to make (a) its
own independent investigation of the financial condition and affairs of the
Borrower in connection with its execution and delivery of this Agreement and
the taking or not taking of any action in connection herewith and (b) its own
appraisal of the creditworthiness of the Borrower and, except as expressly
provided in this Agreement, the Agent shall not have any duty or
responsibility, either initially or on a continuing basis, to provide the
Arranger, the Fronting Bank or any Lender with any credit or other information
with respect thereto, whether coming into its possession before the payment of
Reimbursement Amounts or at any time or times thereafter. The Agent shall not
be responsible to the Arranger, the Fronting Bank or any Lender for any
recitals, statements, information, representations or warranties herein or in
any document, certificate or other writing delivered in connection herewith or
for the execution, effectiveness, genuineness, validity, enforceability,
perfection, collectibility, priority or sufficiency of this Agreement or any
other Financing Document or the financial condition of the Borrower or be
required to make any inquiry concerning either the performance or observance of
any of the terms, provisions or conditions of this Agreement or any other
Financing Document, or the financial condition of the Borrower or the existence
or possible existence of any Default or Event of Default.

                  8.04     Certain Rights of the Agent. If the Agent shall
request instructions from the Fronting Bank or the Lenders with respect to any
act or action (including failure to act) in connection with this Agreement or
any other Financing Document, the Agent shall be entitled to refrain from such
act or taking such action unless and until the Agent shall have received
instructions from the Fronting Bank or the Lenders, as the case may be; and the
Agent shall not incur liability to any Person by reason

                                     -36-
<PAGE>

of so refraining. Without limiting the foregoing, neither the Fronting Bank nor
any Lender shall have any right of action whatsoever against the Agent as a
result of the Agent acting or refraining from acting hereunder or under any
other Financing Document in accordance with the instructions of the Fronting
Bank and the Majority Lenders.

                  8.05     Reliance. The Agent shall be entitled to rely, and
shall be fully protected in relying, upon any note, writing, resolution,
notice, statement, certificate, telex, teletype or telecopier message,
cablegram, radiogram, order or other document or telephone message signed, sent
or made by any Person that the Agent believed to be the proper Person, and,
with respect to all legal matters pertaining to this Agreement and any other
Financing Document and its duties hereunder and thereunder, upon advice of
counsel selected by it.

                  8.06     Indemnification. To the extent the Agent is not
reimbursed and indemnified by the Borrower, the Fronting Bank and each Lender
will reimburse and indemnify the Agent for and against any and all Losses of
whatsoever kind or nature which may be imposed on, asserted against or incurred
by the Agent in performing its duties hereunder or under any other Financing
Document, or in any way relating to or arising out of this Agreement or any
other Financing Document, (a) in the case of the Fronting Bank, in an amount
equal to the Losses less the portion, if any, of such Losses payable by the
Lenders pursuant to clause (b) below, and (b) in the case of any Lender, in an
amount equal to its Percentage of such Losses, provided that the neither the
Fronting Bank nor any Lender shall be liable for any portion of such
liabilities, obligations, losses, damages, penalties, actions, judgments,
suits, costs, expenses or disbursements resulting from the Agent's gross
negligence or willful misconduct; and provided further that upon such
reimbursement and indemnification by the Fronting Bank and the Lenders, the
Fronting Bank and the Lenders shall be subrogated to all rights which the Agent
has with respect thereto.

                  8.07     The Agent in its Individual Capacity. With respect
to its obligation, if any, to pay Reimbursement Amounts under this Agreement,
the Agent shall have the rights and powers specified herein for a "Lender" and
may exercise the same rights and powers as though it were not performing the
duties specified herein. The term "Lender" or any similar term shall, unless
the context clearly otherwise indicates, include the Agent its individual
capacity as a Lender. The Agent may accept deposits from, lend money to, and
generally engage in any kind of banking, trust or other business with the
Borrower or any Affiliate of the Borrower as if it were not performing the
duties specified herein, and may accept fees and other consideration from the
Borrower for services in connection with this Agreement and otherwise without
having to account for the same to the Arranger, the Fronting Bank or the
Lenders.

                  8.08     Resignation by the Agent.

                  (a)      The Agent may resign from the performance of all its
functions and duties hereunder and/or under the other Financing Documents at
any time by giving 30 days' prior written notice to the Borrower, the Fronting
Bank and each Lender; provided, however, that if the Agent shall determine, in
its sole discretion, that its resignation shall be immediately required by law,
no prior notice shall be required. Such resignation shall take effect upon the
appointment of a successor Agent pursuant to clauses (b) and (c) below or as
otherwise provided below.

                  (b)      Upon any such notice of resignation, the Borrower
shall appoint a successor Agent hereunder which shall be a commercial bank or
trust company reasonably acceptable to the Fronting Bank and the Majority
Lenders.

                  (c)      If a successor Agent shall not have been so
appointed within such 30 day period, the Fronting Bank and the Majority Lenders
may then appoint a successor Agent reasonably acceptable to the Borrower who
shall serve as Agent hereunder or thereunder.

                  (d)      If no successor Agent has been appointed pursuant to
clause (b) or (c) above by the 35th day after the date such notice of
resignation was given by the Agent, the Agent's resignation shall become
effective and the Fronting Bank and the Lenders shall thereafter perform all the
duties of the Agent hereunder and/or under any other Financing Document until
such time, if any, as the Borrower appoints a successor Agent as provided above.

                  8.09     Arranger. The Arranger has no duties or
responsibilities to the Agent, the Fronting Bank or the Lenders under this
Agreement or the other Financing Documents. Neither the Arranger nor any of its
officers, directors, agents or employees shall be liable to the Agent, the
Fronting Bank or any Lender for any action taken or omitted by it or them
hereunder or under any Financing Document or in connection herewith or
therewith. The Arranger shall not have by reason of this Agreement or any other
Financing Document a fiduciary relationship in respect of the Agent, the
Fronting Bank or any Lender, and nothing in this Agreement or any other
Financing Document, expressed or implied, is intended to or shall be so
construed as to impose upon the Arranger any obligations in respect of this
Agreement or any other Financing Document.

                  Section 9.        Miscellaneous.

                  9.01     Indemnification.

                  (a)      The Borrower agrees to indemnify and hold the Agent,
the Arranger, the Fronting Bank and each Lender harmless from and against any
and all Losses which the Agent, the Arranger, the Fronting Bank or any Lender
may incur or which may be claimed against the Agent, the Arranger, the Fronting
Bank or any Lender by any person or entity by reason of or in connection with
(i) the execution, delivery and performance of this Agreement, the other
Financing Documents and the Bond Documents, or (ii) the payment or failure to
make lawful payment under this Agreement; provided, however, that the Borrower
shall not be required to indemnify the Agent, the Arranger, the Fronting Bank
or any Lender for any Losses to the extent caused by (A) the failure of such
Person to satisfy its obligations under this Agreement, or (B) such Person's
gross negligence or willful misconduct.

                                     -38-
<PAGE>

For purposes of clause (B) of the preceding sentence, the gross negligence or
willful misconduct of a Person in one capacity shall be attributed to the same
Person in all other capacities. Nothing in this Section 9.01(a) is intended to
limit the Borrower's obligations contained in this Agreement. Without prejudice
to the survival of any other obligations of the Borrower herein contained, the
obligations of the Borrower set forth in this Section 9.01(a) shall survive the
payment in full of amounts payable hereunder and the termination of this
Agreement.

                  (b)      In case any claim is asserted or any action or
proceeding covered by the indemnification provisions hereof is brought against
any person entitled to indemnification hereunder (any such person, the
"Indemnitee"), the Indemnitee shall promptly notify the party hereunder required
to indemnify such person (the "Indemnitor") in writing of such claim, action or
proceeding, and the Indemnitor shall resist, settle or defend such claim, action
or proceeding. If, within 10 Business Days after the Indemnitor's receipt of
such notice, the Indemnitor does not commence and continue to prosecute the
defense of such claim, action or proceeding, or if there exists a conflict which
would or does preclude the Indemnitor from representing the Indemnitee's
interest, the Indemnitee may, upon 5 Business Days' notice, retain counsel to
represent it in such defense and the reasonable fees and expenses of the
Indemnitee's counsel shall be deemed to be an expense payable by the Indemnitor
for the purpose of this Section 9.01. Subject to the foregoing, the Indemnitee
shall cooperate and join with the Indemnitor, at the expense of the Indemnitor,
as may be required in connection with any action taken or defended by the
Indemnitor.

                  9.02     Right of Setoff. If an Event of Default shall have
occurred and be continuing, the Agent, on behalf of itself, the Fronting Bank
and each Lender, is hereby authorized at any time and from time to time, to the
fullest extent permitted by law, to set off and apply any and all deposits
(general or special, time or demand, provisional or final) at any time held and
other indebtedness at any time owing by the Agent to or for the credit or the
account of the Borrower against any and all of the obligations of the Borrower
then existing under this Agreement held by the Agent. The right of the Agent
under this Section 9.02 is in addition to other rights and remedies which the
Agent, the Fronting Bank or such Lender may have. Promptly following any
exercise of the right of setoff, the Agent shall give the Borrower written
notice thereof.

                  9.03     Notices. Except as otherwise expressly provided
herein, all notices, demands and other communications provided for hereunder

upon and inure to the benefit of the parties hereto and their respective
successors and assigns, except that (i) the Borrower may not assign or
otherwise transfer any of its rights or obligations under this Agreement except
in connection with a merger, consolidation or transfer of assets permitted
under Section 5.01 hereof, (ii) the Fronting Bank may not assign or otherwise
transfer any of its obligations under the Letters of Credit, (iii) neither the

                  (b)      The Fronting Bank and each Lender may, with the
prior written consent of the Agent, not to be unreasonably withheld or delayed

based upon the lack of creditworthiness or perceived lack of creditworthiness
of the proposed transferee shall, in all cases, be deemed "reasonable"), and,
so long as no Default or Event of Default has occurred and is continuing, the
Borrower, not to be unreasonably withheld or delayed, assign to one or more
assignees all or a portion of its Fronting Bank Interests and, in the case of a
Lender, its Commitment hereunder; provided, however, that (i) the consent of
the Borrower shall not be required in the case of an assignment to an assignee
that is already a Lender; (ii) each such assignment shall be of a constant, and
not a varying, percentage of Fronting Bank Interests and Commitment; (iii) no
partial assignment shall, as of the effective date of such assignment, result
in the sum of the assigning Lender's Commitment and Fronting Bank Interests
being less than $5,000,000, this Section 9.04(b)(iii) being inapplicable to an
assignment among and between the Fronting Bank, the Lenders and their
respective Affiliates; (iv) no partial assignment shall, as of the effective
date of such assignment, result in the assignee holding a Commitment and
Fronting Bank Interests in an aggregate amount less than $5,000,000, this
Section 9.04(b)(iv) being inapplicable to an assignment among and between the
Fronting Bank, the Lenders and their respective Affiliates; (v) no assignment
shall, as of the effective date of such assignment, increase the Borrower's
obligations, if any, to the assignee under any

                                     -40-

Financing Document, including, without limitation, Sections 2.03(i), 2.04, 2.05,
2.06 or 9.01 of this Agreement as of such date beyond those obligations, if any,
owing as of such date to the Fronting Bank or the assigning Lender, as the case
may be; and (vi) the parties to each such assignment shall execute and deliver
to the Agent an Assignment and Acceptance and the assigning Lender shall deliver
to the Agent a processing and recordation fee of $3,500 which shall not be
payable by the Borrower. The Agent shall deliver a copy of any such Assignment
and Acceptance to the Borrower and the Fronting Bank promptly after receipt
thereof. Upon acceptance and recording pursuant to paragraph (e) of this Section
9.04, from and after the effective date specified in each Assignment and
Acceptance, which effective date shall be at least five Business Days after the
execution thereof, (A) the assignee thereunder shall become a party hereto and,
to the extent provided in such Assignment and Acceptance, have the rights and
obligations of a Lender under this Agreement as well as the rights in the
Fronting Bank Interests so assigned and (B) the Fronting Bank or the assigning
Lender, as the case may be, thereunder shall, to the extent provided in such
assignment, cease to have any rights in the Fronting Bank Interests and, in the
case of an assigning Lender, the Commitment or part thereof so assigned.

                  (c)      By executing and delivering an Assignment and
Acceptance, the Fronting Bank or the assigning Lender thereunder and the
assignee thereunder shall be deemed to confirm to and agree with each other and
the other parties hereto as follows: (i) other than the representation and
warranty that it is the legal and beneficial owner of the Fronting Bank
Interests being assigned thereby free and clear of any adverse claim, the
Fronting Bank or the assigning Lender, as the case may be, makes no
representation or warranty and assumes no responsibility with respect to any
statements, warranties or representations made in or in connection with its
Agreement or the execution, legality, validity, enforceability, genuineness,
sufficiency or value of this Agreement, any other Financing Document or any
other instrument or document furnished pursuant hereto or thereto; (ii) the
Fronting Bank or the assigning Lender, as the case may be, makes no
representation or warranty and assumes no responsibility with respect to the
financial condition of the Borrower or the performance or observance by the
Borrower of any of its obligations under this Agreement, any other Financing
Document or any other instrument or document furnished pursuant hereto or
thereto; (iii) such assignee confirms that it has received a copy of this
Agreement, together with copies of such other documents and information as it
has deemed appropriate to make its own credit analysis and decision to enter
into such Assignment and Acceptance and this Agreement; (iv) such assignee will
independently and without reliance upon the Agent, the Fronting Bank or any
Lender and based on such documents and information as it shall deem appropriate
at the time, continue to make its own credit decisions in taking or not taking
action under this Agreement; (v) such assignee appoints and authorizes the
Agent to take such action as agent on its behalf and to exercise such powers
under this Agreement and any other Financing Document as are delegated to the
Agent by the terms hereof and thereof, together with such powers as are
reasonably incidental thereto; and (vi) such assignee agrees that it will
perform in accordance with their terms all the obligations which by the terms
of this Agreement and any other Financing Document are required to be performed
by it as a Lender.

                  (d)      The Agent shall maintain at its address set forth in
Section 9.03, a copy of each Assignment and Acceptance delivered to it and a
register (the "Register") for the recordation of (i) the name and address of
the Fronting Bank and the amount of its Fronting Bank Interests and (ii) the
names and addresses of the Lenders and their respective Commitments,
Percentages and participation interests in the Fronting Bank Interests. The
entries in the Register shall be conclusive, absent manifest error, and

                                     -41-
<PAGE>

the Borrower, the Agent, the Fronting Bank and the Lenders may treat each Person
whose name is recorded in the Register pursuant to the terms hereof as the owner
of any Fronting Bank Interests as the owner thereof for all purposes of this
Agreement. The Register shall be available for inspection by the Borrower, the
Fronting Bank and any Lender at any reasonable time and from time to time upon
reasonable prior notice.

                  (e)      Upon its receipt of a duly completed Assignment and
Acceptance executed by the Fronting Bank or an assigning Lender and an assignee
together with the processing and recordation fee referred to in paragraph (b)
above, the Agent shall (subject, so long as no Default or Event of Default has
occurred and is continuing, to the consent of the Borrower to such assignment
which consent shall not be unreasonably withheld or delayed), (i) accept such
Assignment and Acceptance, (ii) modify the Register to reflect the Commitment,
Percentage and amount of Fronting Bank Interests of the assignee Lender and the
reduced Fronting Bank Interests of the Fronting Bank or the assigning Lender, as
the case may be, and (iii) give prompt notice thereof to the Borrower and the
Fronting Bank.

                  (f)      The Fronting Bank and each Lender may without the
consent of the Borrower sell subparticipation interests to one or more banks or
other entities in all or a portion of its Fronting Bank Interests or
participation interests therein; provided, however, that (i) the Fronting
Bank's or such Lender's obligations, and the Borrower's obligations, under this
Agreement shall remain unchanged, (ii) the Fronting Bank or such Lender shall
remain solely responsible to the other parties hereto for the performance of
such obligations, (iii) a Participant shall be entitled to the benefit of the
cost protection provisions contained in Sections 2.03(i), 2.04, 2.05, 2.06, and
9.01 to the same extent that the Fronting Bank or the Lender from which such
Participant acquired its subparticipation would be entitled to the benefit of
such cost protection provisions if such subparticipation had not been sold,
granted or assigned, (iv) no subparticipation shall increase the Borrower's
obligations hereunder beyond those that exist in favor of the Fronting Bank or
the Lender granting such subparticipation; and (v) the Borrower, the Fronting
Bank, the Agent and the other Lenders shall continue to deal solely and
directly with the Fronting Bank or such Lender in connection with the Fronting
Bank's or such Lender's rights and obligations under this Agreement, and the
Fronting Bank or such Lender shall retain the sole right to enforce the
obligations of the Borrower hereunder and to approve any amendment,
modification or waiver of any provision of this Agreement or any other
Financing Document (other than amendments, modifications or waivers which (A)
waive or reduce fees payable hereunder, (B) waive or reduce the amount of
principal of or the rate at which default interest is payable on Reimbursement
Obligations, (C) change the dates fixed for payments of such amounts, (D)
increase the aggregate Stated Amount of the Letters of Credit or the granting
Lender's Commitment and (E) extend the Termination Date of any Letter of
Credit).

                  9.05     No Waiver; Remedies Cumulative. No failure or delay
on the part of the Agent, the Fronting Bank or any Lender in exercising any
right, power or privilege hereunder or under any other Financing Document and
no course of dealing between the Borrower, the Agent, the Fronting Bank or any
Lender shall operate as a waiver thereof; nor shall any single or partial
exercise of any right, power or privilege hereunder or under any other
Financing Document preclude any other or further exercise thereof or the
exercise of any other right, power or privilege hereunder or thereunder. The
rights, powers and remedies herein or in any other Financing Document expressly
provided are cumulative and not exclusive of any rights, powers or remedies
which the Agent, the Fronting Bank or

                                     -42-
<PAGE>

any Lender would otherwise have. No notice to or demand on the Borrower in any
case shall entitle the Borrower to any other or further notice or demand in
similar or other circumstances or constitute a waiver of the rights of the
Agent, the Fronting Bank or any Lender to any other or further action in any
circumstances without notice or demand.

                  9.06     Payments Pro Rata. The Fronting Bank and each Lender
agrees that if it should receive any amount hereunder (whether by voluntary
payment, by realization upon security, by the exercise of the right of setoff or
banker's lien, by counterclaim or cross action, by the enforcement of any right
under the Financing Documents, or otherwise) which is applicable to the payment
of the principal of, or interest on, Reimbursement Obligations or fees, which
with respect to the related amount or amounts received by the Fronting Bank
and/or other Lenders is in a greater proportion than the total amount of such
Reimbursement Obligations or fees then owed and due to the Fronting Bank or such
Lender bears to the total amount of such Reimbursement Obligations or fees then
owed and due to the Fronting Bank and/or all of the Lenders immediately prior to
such receipt, then the Fronting Bank or such Lender receiving such excess
payment shall purchase for cash without recourse or warranty from the Fronting
Bank and/or the other Lenders an interest in the Reimbursement Obligations or
fees then owed to the Fronting Bank and/or such Lenders in such amount as shall
result in a proportional participation by the Fronting Bank and/or all of the
Lenders in such amount; provided, however, that if all or any portion of such
excess amount is thereafter recovered from the Fronting Bank or such Lender,
such purchase shall be rescinded and the purchase price restored to the extent
of such recovery, but without interest.

                  9.07     Governing Law; Submission to Jurisdiction; Venue.

                  (a)      THIS AGREEMENT AND THE RIGHTS AND OBLIGATIONS OF THE
PARTIES HEREUNDER SHALL BE CONSTRUED IN ACCORDANCE WITH AND BE GOVERNED BY THE
LAW OF THE STATE OF NEW YORK, WITHOUT REGARD TO PRINCIPLES OF CONFLICTS OF LAW.

                  (b)      Any legal action or proceeding against the Borrower
with respect to this Agreement may be brought in any court of the State of New
York sitting in the Borough of Manhattan or in the United States District Court
for the Southern District of New York, and, by execution and delivery of this
Agreement, the Borrower hereby irrevocably accepts for itself and in respect of
its property, generally and unconditionally, the jurisdiction of the aforesaid
courts for such purposes.

                  (c)      The Borrower hereby irrevocably waives any objection
which it may now or hereafter have to the laying of venue of any of the
aforesaid actions or proceedings arising out of or in connection with this
Agreement brought in the courts referred to in clause (b) above and hereby
further irrevocably waives and agrees not to plead or claim in any such court
that any such action or proceeding brought in any such court has been brought
in an inconvenient forum.

                  9.08     Amendment or Waiver. Neither this Agreement nor any
terms hereof (other than the provisions of Sections 7 and 8) may be changed,
waived, discharged or terminated unless such change, waiver, discharge or
termination has been consented to in writing signed by the Agent, the Fronting
Bank, the Majority Lenders and the Borrower; provided, however, that no such
change, waiver, discharge or termination shall, without the consent of each
Lender, (a) extend the final maturity

                                     -43-
<PAGE>

of any Reimbursement Obligation, or reduce the rate or extend the time of

the Commitment of any Lender over the amount thereof then in effect, (b) reduce
the amount of any fee payable to such Lender or change the time for payment of
any such fee, (c) amend, modify or waive any provision of this Section 9.08 or
Sections 2.03(i), 2.04(a), 2.04(b), 2.04(d), 2.05, 2.06, 8.06, 9.01, 9.04 or
9.06, (d) consent to the assignment or transfer by the Borrower of any of its
rights and obligations under this Agreement or any other Financing Document, (e)
extend the scheduled expiration date of any Letter of Credit pursuant to Section
2.11, (f) amend or modify the defined terms "Majority Lenders" or "Advance
Repayment Date" or "Applicable Fee" or "Applicable Margin", or (g) release the
Collateral other than pursuant to Section 6.02(a). The provisions of Sections 7
and 8 (except for Section 8.08) may only be amended or waived by a written
instrument signed by the Agent, the Fronting Bank and the Majority Lenders.
Section 8.08 may only be amended or waived by a written instrument signed by the
Borrower, the Agent, the Fronting Bank and the Majority Lenders.

                  9.09     Termination of Letters of Credit; Survival. The
Borrower may, if the Applicable Indenture so provides, without penalty, replace
or terminate any Letter of Credit issued hereunder at any time. Except for the
Borrower's indemnification obligations under this Agreement, which
indemnification obligations shall expressly survive the termination of this
Agreement, this Agreement shall terminate as soon as all Letters of Credit
issued hereunder have terminated in accordance with their terms and all
reimbursement obligations of the Borrower set forth herein shall have been paid
in full.

                  9.10     Entire Agreement. This Agreement and the other
Financing Documents constitute the entire contract between the parties relative
to the subject matter hereof. Any previous agreement among the parties with
respect to the subject matter hereof is superseded by this Agreement and the
other Financing Documents. Nothing in this Agreement or in the other Financing
Documents, expressed or implied, is intended to confer upon any party other
than the parties hereto any rights, remedies, obligations or liabilities under
or by reason of this Agreement or the other Financing Documents.

                  9.11     Counterparts. This Agreement may be executed in any
number of counterparts and by the different parties hereto on separate
counterparts, each of which when so executed and delivered shall be an
original, but all of which shall together constitute one and the same
instrument. A set of counterparts executed by all the parties hereto shall be
lodged with the Borrower and the Agent.

                  9.12     Severability. Any provision of this Agreement that
is prohibited or unenforceable in any jurisdiction shall, as to such
jurisdiction, be ineffective to the extent of such prohibition or
unenforceability without invalidating the remaining provisions hereof or
affecting the validity or enforceability of such provision in any other
jurisdiction.

                  9.13     Nature of Duties.

                  (a)      None of the Agent, the Fronting Bank or the Lenders
shall be responsible: (i) for the form, validity, accuracy, genuineness, or
legal effect of any document submitted by any party to the Fronting Bank in
connection with the application for and issuance of or payment under any Letter
of Credit, even if it should in fact prove to be in any or all respects
invalid, inaccurate, fraudulent, or forged; (ii) for the validity of any
instrument transferring or assigning or purporting to transfer or assign

                                     -44-
<PAGE>

any Letter of Credit or the rights or benefits thereunder or proceeds thereof,
in whole or in part, which may prove to be invalid or ineffective for any
reason; (iii) for errors, omissions, interruptions, or delays in transmission or
delivery of any messages, by mail, cable, telegraph, telex, or otherwise,
whether or not they be in cipher; and (iv) for any consequences arising from
causes beyond the control of the Agent, the Fronting Bank or the Lenders,
including, without limitation, any acts by Governmental Authorities; provided
that, the Borrower shall have a claim against the Fronting Bank and the Fronting
Bank shall be liable to the Borrower, to the extent, but only to the extent, of
any direct, as opposed to consequential, damages suffered by the Borrower which
were caused by (A) the Agent's, the Fronting Bank's or any Lender's willful
misconduct or gross negligence in determining whether documents presented under
any Letter of Credit complied with the terms thereof or (B) the Fronting Bank's
willful failure or gross negligence to pay under any Letter of Credit after the
presentation to it by the beneficiary thereof of a demand and certificate
strictly complying with the terms and conditions of such Letter of Credit.

                  (b)      The Borrower assumes all risks associated with the
acceptance by the Fronting Bank of any proper draw certificate received by
telecommunication, it being agreed that the use of telecommunication devices is
for the benefit of the Borrower and that the Fronting Bank and Lenders assume
no liabilities or risks with respect to the receipt of any proper draw
certificate by telecommunication device.

                  9.14     Fronting Bank Cooperation. The Fronting Bank agrees
to cooperate with the Borrower in connection with the sale and remarketing of
Bonds by providing the Borrower with (a) current disclosure regarding the
Fronting Bank for inclusion in any Official Statement, (b) customary closing
certificates and (c) customary legal opinions.

Direct-Pay Letter of Credit No. [___________] in the amount of $[___________]
(hereinafter, as reduced and reinstated from time to time in accordance with
the provisions hereof, the "Stated Amount"), of which (a) an amount not
exceeding $[___________] (as reduced and reinstated from time to time in
accordance with the terms hereof, the "Principal Component") may be drawn upon
with respect to payment of the unpaid principal amount of Bonds at maturity,
upon acceleration or upon redemption or the portion of the purchase price
corresponding to principal of Bonds delivered for purchase under the Indenture
and either not remarketed or for which no remarketing proceeds have been
received prior to such drawing and (b) an amount not exceeding $[_________] (as
reduced and reinstated from time to time in accordance with the terms hereof,
the "Interest Component") may be drawn upon with respect to payment of accrued
interest on the Bonds or the portion of the purchase price of Bonds so
delivered for purchase corresponding to interest accrued on the Bonds on or
prior to the stated maturity thereof, effective immediately and expiring at the
close of business on [___________] unless terminated earlier in accordance with
the provisions hereof.

                  Funds under this Letter of Credit will be made available to

specifying the type of Drawing or Drawings being made as follows:

<PAGE>
                                                                      Exhibit C
                                                                         Page 2

Sections [___] and [___] of the Indenture which Bonds have either not been
remarketed or for which no remarketing proceeds have been received prior to
such drawing (an ""A" Drawing");

                  (B)      a drawing with respect to the payment of principal
of the Bonds, whether at maturity or upon acceleration or redemption pursuant
to Sections [___] and [___] of the Indenture (a ""B" Drawing");

                  (C)      a drawing with respect to the payment of the portion

interest or with respect to the payment of interest in accordance with Section

                  An "A" Drawing and a "C" Drawing made to purchase Bonds
tendered at the request of the holders thereof pursuant to Section [___] of the
Indenture is hereinafter collectively referred to as a "Liquidity Drawing."

                  Such certificate or certificates shall be appropriately
completed and executed by a purported Authorized Officer (as hereinafter
defined) and shall be presented only on a Business Day (as hereinafter defined)
to us by facsimile (to facsimile number (212) 266-7427 or such other facsimile
number as may be designated by us in writing to you from time to time). Prior
to, or contemporaneously with, the presentation of a certificate or
certificates hereunder, you shall use best efforts to give telephonic notice
(by call to telephone number (212) 266-7255 or such other number designated by
us in writing to you from time to time) of your intention to present such
certificate or certificates and stating the amount or amounts to be demanded;
provided, however, that such telephonic notice and subsequent overnight
delivery shall not be conditions precedent to our obligation to honor a drawing
otherwise made in compliance with the terms hereof.

                  Demands for payment may be made by you under this Letter of
Credit at any time during our business hours at our aforesaid address on a
Business Day (as hereinafter defined). If demand for payment (other than a
Liquidity Drawing) is made by you hereunder at or prior to 10:00 a.m. on a
Business Day and such demand for payment and the documents presented in
connection therewith conform to the terms and conditions hereof, payment shall
be made to you or to your designee by wire transfer of the amount demanded, in
same day funds, not later than 2:00 p.m. on the same Business Day or such later
Business Day as you may specify in your demand. If demand for payment (other
than a Liquidity Drawing) is made by you hereunder after 10:00 a.m. on a
Business Day and such demand for payment and the documents presented in
connection therewith conform to the terms and conditions hereof, payment shall
be made to you or to your designee by wire transfer of the amount demanded, in
same day funds, not later than 2:00 p.m. on the next succeeding Business Day or
such later Business Day as you may specify in your demand. If demand for
payment pursuant to a Liquidity Drawing is made by you hereunder at or prior to
1:00 p.m. on a Business Day and such demand for payment and the documents
presented in connection therewith conform to the terms and conditions hereof,
payment shall be made to you or to your designee by wire transfer of the amount
demanded, in

                                                                         Page 3

same day funds, not later than 3:00 p.m. on the same Business Day or such later
Business Day as you may specify in your demand. If demand for payment pursuant
to a Liquidity Drawing is made by you hereunder after 1:00 p.m. on a Business
Day and such demand for payment and the documents presented in connection
therewith conform to the terms and conditions hereof, payment shall be made to
you or to your designee by wire transfer of the amount demanded, in same day
funds, not later than 3:00 p.m. on the next succeeding Business Day or such
later Business Day as you may specify in your demand.

                  If requested by you, payment under this Letter of Credit will
be made by deposit of same day funds into a designated account that you
maintain with us. All payments hereunder will be made with our own funds.

                  Demands for payment hereunder honored by us shall not, in the
aggregate, exceed the Stated Amount, as the Stated Amount may have been
reinstated by us as provided in the second succeeding paragraph. Subject to the
preceding sentence, each "A" Drawing and each "B" Drawing honored hereunder
shall pro tanto reduce the Principal Component, and each "C" Drawing and "D"
Drawing honored hereunder shall pro tanto reduce the Interest Component. Any
such reduction in accordance with the preceding sentence shall result in a
corresponding reduction in the Stated Amount, it being understood that after
the effectiveness of any such reduction you shall no longer have any right to
make a drawing hereunder in respect of the amount of such principal of and/or
interest on the Bonds or the payment of the purchase price corresponding
thereto.

                  Upon receipt by us of a Notice of Reduction or Termination in
the form attached hereto as Exhibit B signed on your behalf by a purported
Authorized Officer (as hereinafter defined) and appropriately completed, this
Letter of Credit shall be terminated, or the Stated Amount, the Principal
Component and/or the Interest Component, as the case may be, shall thereupon be
reduced by the amount specified therein.

                  Following any "A" Drawing, and for the corresponding "C"
Drawing, if any, immediately upon our being fully reimbursed therefor the
Stated Amount and the Principal Component shall be reinstated (effective on
such reimbursement) by the amount of such "A" Drawing and, if applicable, the
Stated Amount and the Interest Component shall be reinstated (effective on such
reimbursement) by the amount of such "C" Drawing; provided, however, the Stated
Amount, the Principal Component and the Interest Component shall be permanently
reduced to zero and shall not be reinstated once the Bank has honored an "A"
Drawing and/or a "C" Drawing made to purchase Bonds at our direction following
a Change in Control or an Event of Default under, and as defined in, the
Reimbursement Agreement, dated as of May 1, 2000, among the Company, the
financial institutions described as Lenders therein, the Agent for the Lenders
and us (the "Reimbursement Agreement"). In addition, if you shall not have
received, within seven calendar days after any payment in respect of a "D"
Drawing, written notice from us to the effect that an Event of Default under
the Reimbursement Agreement has occurred and is continuing and that we are not
reinstating the Interest Component, the Stated Amount and the Interest
Component will automatically be reinstated, as of the close of business

the amount thereof.

                  Only you or your successor as trustee under the Indenture may
make a drawing under this Letter of Credit. Upon payment to you, to your
designee or to your account of the amount demanded hereunder, we shall be fully
discharged of our obligation under this Letter of Credit with respect to such
demand for payment and we shall not thereafter be obligated to make any further
payments under this Letter of Credit in respect of such demand for payment to
you or any other person who may have made to you or makes a demand for payment
of principal of, purchase price of, or interest on, any Bond. By paying to you,
to your designee or to your account an amount demanded in accordance herewith,
we make no representation as to the correctness of the amount demanded.

                  This Letter of Credit applies only to the payment of
principal or the portion of the purchase price of Bonds corresponding to
principal and the payment of up to 45 days' interest or the portion of the
purchase price corresponding to up to 45 days' interest (computed at an assumed
rate of 12% per annum calculated on the basis of a 365 day year) accruing on
the Bonds on or prior to the expiration of this Letter of Credit and does not
apply to any interest that may accrue thereon or any principal which may be
payable with respect thereto after such date.

                  Upon the earliest of (i) the making by you of the final
drawing available to be made hereunder and payment thereof, (ii) the expiration
date stated above, or (iii) the surrender by you to us of this Letter of Credit
in connection with delivery of a certificate in the form of Exhibit B attached
hereto stating that this Letter of Credit is terminated, this Letter of Credit

not in part) to a successor trustee properly appointed and qualified pursuant
to Section [___] of the Indenture (a "Transferee"), and such transferred Letter
of Credit may be successively transferred. If this Letter of Credit is
transferred to a Transferee, all references to the Trustee in this Letter of
Credit and the certificates attached hereto shall be deemed references to such
Transferee. Transfer of the balance available to be drawn under this Letter of
Credit to a Transferee shall be effected by a request which shall (i) be in the

material respects as of the date hereof except for (i) any representations and
warranties that expressly relate solely to an earlier date, which
representations and warranties were true and accurate in all material respects

the Borrower or its organizational documents, or result in a breach of, or
constitute a default under any existing indenture or credit agreement or any
other agreement or instrument to which the Borrower is a party or by which its
properties may be bound or affected, except where the failure to have such
consent or approval or such violation, breach of default could not reasonably
be expected to result in a material adverse effect on the business, financial
condition or results of operations of the Borrower and its Subsidiaries taken
as a whole, and (B) will not conflict with, or result in a breach of the terms,
conditions or provisions of, or constitute a default under, the Certificate of
Incorporation or Bylaws of the Borrower or of any agreement or instrument to
which the Borrower is now a party, which breach would have a material adverse
effect on the business, financial condition or results of operations of the
Borrower and its Subsidiaries taken as a whole.
